1 Changes with Apache 2.1.3
3 [Remove entries to the current 2.0 section below, when backported]
5 *) Start keeping track of time-taken-to-process-request again for
6 mod_status if ExtendedStatus is enabled. [Jim Jagielski]
8 *) mod_cache: Add CacheStorePrivate and CacheStoreNoStore directive.
11 *) Remove compiled-in upper limit on LimitRequestFieldSize.
14 *) mod_ldap: Added the directive LDAPConnectionTimeout to configure
15 the ldap socket connection timeout value.
18 *) Add --enable-pie flag to configure, to build httpd as a Position
19 Independent Executable where supported (GCC/binutils).
22 *) proxy_balancer: Add in load-balancing via weighted traffic
23 byte count. [Jim Jagielski]
25 *) mod_disk_cache: Cache r->err_headers_out headers. This allows CGI
26 scripts to be properly cached. [Justin Erenkrantz, Sander Striker]
28 *) mod_ldap: Updated to use the new apr-util v1.1 apr_ldap_*_option()
29 API for the setting of server and client SSL certificates. Replaced
30 LDAPTrustedCA directive with LDAPTrustedGlobalCert and
31 LDAPTrustedClientCert directives to correctly support global certs
32 (CA certs / Netware client certs) and per connection client certs
33 as supported by Netware, OpenLDAP and Netscape/Mozilla.
36 *) mod_proxy: Handle client-aborted connections correctly. PR 32443.
37 [Janne Hietamäki, Joe Orton]
39 *) mod_cache: Remove unimplemented CacheForceCompletion directive.
42 *) support/check_forensic: Fix temp file usage
43 [Javier Fernandez-Sanguino Pen~a <jfs computer.org>]

46 which can be used to configure a specific list of CA names to send
47 in a client certificate request. PR 32848.
48 [Tim Taylor <tim.taylor dfas.mil>]
50 *) --with-module can now take more than one module to be statically
51 linked: --with-module=<modtype>:<modfile>,<modtype>:<modfile>,...
52 If the <modtype>-subdirectory doesn't exist it will be created and
53 populated with a standard Makefile.in. [Erik Abele]
55 *) Remove some compiler warnings within the LDAP modules [Graham Leggett]
57 *) Add a build script to create a solaris package. [Graham Leggett]
59 *) ap_http_scheme() replaced with ap_http_method() - this function
60 returns the scheme (http v.s. https).
63 *) mod_proxy: Fix a request corruption problem and a buffering problem
64 which sometimes prevented proxy-sendchunks from working.
67 *) Fix the RPM spec file so that an RPM build now works. An RPM
68 build now requires system installations of APR and APR-util.
71 *) Significantly simplify the load balancer scheduling algorithm
72 for the proxy BalancerMember weighting. loadfactors (lbfactors)
73 are now normalized with respect to each other. [Jim Jagielski]
75 *) mod_dumpio: Added to the available module suite; it is an
76 I/O logging/dumping module. Placed in the (new) debug module
77 subdirectory. mod_bucketeer moved to that directory as well.
80 *) core: Add support for APR_TCP_DEFER_ACCEPT to defer accepting
81 of a connection until data is available.
84 *) conf: Remove AddDefaultCharset from the default configuration because
85 setting a site-wide default does more harm than good. PR 23421.
88 Changes with Apache 2.1.2
90 *) mod_proxy: Respect errors reported by pre_connection hooks.
93 *) worker MPM: Fix a problem which could cause httpd processes to
94 remain active after shutdown. [Jeff Trawick]
96 *) core: Error out on sections that are missing an argument instead of
97 silently consuming the section. PR 25460.
98 [Geoffrey Young, Paul Querna]
100 *) mod_cache/mod_mem_cache/mod_disk_cache: Move out of experimental.
102 *) Upgraded PCRE to version 5.0. [Brian Pane]
104 *) mod_cgid: Catch configuration problem where two web server instances
105 share same ServerRoot but admin forgot to use ScriptSock.
108 *) mod_cgi: Ensure that all stderr is logged for a script which returns
109 a Location header to generate a non-local redirect. PR 20111.
112 *) Added the Event MPM to more efficiently handle clients during a
114 [Paul Querna, Greg Ames]
116 Changes with Apache 2.1.1
118 *) mod_proxy_http: Stream content better - always flush buffered data to
119 the client before blocking waiting for new data. PR 19954.
122 *) mod_ssl: Add support for command-line option "-t -DDUMP_CERTS" which
123 will dump the filenames of all configured SSL certificates to stdout.
126 *) mod_disk_cache: Remove a bunch of non-implemented garbage collection
127 and cache size directives that are now available through htcacheclean.
130 *) Add htcacheclean to support/ for assistance with mod_disk_cache.
133 *) mod_authnz_ldap: Added the directive "Requires ldap-filter" that
134 allows the module to authorize a user based on a complex LDAP
135 search filter. [Brad Nicholes]
137 *) mod_usertrack: Run the fixups hook before other modules.
138 PR 29755. [Paul Querna]
140 *) Allow mod_authnz_ldap authorization functionality to be used
141 without requiring the user to also be authenticated through
142 mod_authnz_ldap. This allows other authentication modules to
143 take advantage of LDAP authorization only [PR 28253]
144 [Jari Ahonen jah progress.com, Brad Nicholes]
146 *) Log the client IP address when an error occurs disabling nagle on a
147 connection, but log at a severity of debug since this error
148 generally means that the connection was dropped before data was
149 sent. Log the client IP address when reporting errors in the core
150 output filter. [Jeff Trawick]
152 *) Add ap_log_cerror() for logging messages associated with particular
153 client connections. [Jeff Trawick]
155 *) core: Add a warning message if the request line read fails.
158 *) mod_cache: Add CacheIgnoreHeaders directive. PR 30399.
159 [Rüiger Plü <r.pluem t-online.de>]

162 core LimitInternalRecursion directive. [André Malo]
164 *) mod_auth_ldap: Handle the inconsistent way in which the MS LDAP
165 library handles special characters. PR 24437 [Jess Holle]
167 *) Unix MPMs: Shut down the server more quickly when child processes are
168 slow to exit. [Joe Orton, Jeff Trawick]
170 *) mod_info: Added listing of the Request Hooks and added more build
171 information like 'httpd -V' contains. Changed output to XHTML.
174 *) mod_info: Rewrote config tree walk using a recursive function.
175 Added ?config option. Added printout of config filename and line numbers.
176 [Rici Lake <rici ricilake.net>, Paul Querna]
178 *) mod_proxy: Fix type error that prevents proxy-sendchunks from working.
181 *) mod_proxy: Fix data corruption by properly setting aside buckets.
184 *) mod_proxy: If a request has a blank body and has a 0 Content-Length
185 headers, pass that to the proxy. [Justin Erenkrantz]
187 *) Recognize QSA flag in mod_rewrite again.
188 [Jan Kratochvil <rcpt-dev.AT.httpd.apache.org jankratochvil.net>]
190 *) Restructured mod_auth_ldap to fit the new authentication model.
191 The module is now called authnz_ldap and has been moved out of
192 the modules/experimental area and into modules/aaa with the other
193 auth modules. Both the authn_ldap provider and the authz_ldap
194 handler are contained within the authnz_ldap module. The
195 authz_ldap handler introduces 3 new "requires" values for handling
196 authorization. These handlers are ldap-user, ldap-group and
197 ldap-dn. [Brad Nicholes]
199 *) Fix some compiler warnings in proxy
200 [Geoffrey Young <geoff@modperlcookbook.org>]
202 *) mod_ssl: Add SSL_CLIENT_V_REMAIN variable, representing the
203 number of days until the client cert expires. [Joe Orton]
205 *) Add test_config hook, run only if httpd is invoked using -t.
208 *) Improve error handling for corrupted pid files. [Jeff Trawick]
210 *) mod_proxy.c and proxy_util.c: Enable compiling on 2.0-HEAD
211 (for backwards compatibility):
212 Avoids mod_ssl.h (not included in 2.0-HEAD) and
213 use apr_socket_create_ex for 0.9.x
216 *) Added proxy_ajp.c module for proxy support to ajp:// backends.
217 [Jean Frederic Clere]
219 *) Fixes the build of proxy on Windows. Since the proxy_module is declared
220 as extern using AP_MODULE_DECLARE_DATA that expands to dllexport, there
221 is a LNK2001 error when building proxy_http. [Mladen Turk]
223 *) Remove LDAP toolkit specific code from util_ldap and mod_auth_ldap.
226 *) Remove deprecated/removed APR_STATUS_IS_SUCCESS(). [Justin Erenkrantz]
228 *) perchild MPM: Fix thread safety problem in the use of longjmp().
229 [Tsuyoshi SASAMOTO <nazonazo super.win.ne.jp>]
231 *) Add load balancer support to the scoreboard in preparation for
232 load balancing support in mod_proxy. [Mladen Turk]

235 allow a non-secure connection to be upgraded to secure connections
238 *) core: Add Options= syntax to AllowOverride to specify which options
239 may be overridden in .htaccess files. PR 29310.
240 [Tom Alsberg <alsbergt cs.huji.ac.il>, Paul Querna]
242 *) ab: Handle long URLs with an error instead of an buffer overflow.
243 PR 28204. [Erik Weide <erik.weidel mplus-technologies.de>, Paul Querna]
245 *) mod_so, core: Add new command line options to print all loaded
246 modules. '-t -D DUMP_MODULES' and '-M' will show all static
247 and shared modules as loaded from the configuration file.
250 *) mod_autoindex: Add ShowForbidden to IndexOptions to list files
251 that are not shown because the subrequest returned 401 or 403.
252 PR 10575. [Paul Querna]
254 *) mod_headers: implement "Early" processing option in post_read_request
255 to enable Header and RequestHeader directives to be used to set up
256 testcases for pre-fixups request phases [Nick Kew]
258 *) mod_proxy: multiple bugfixes, principally support cookies in
259 ProxyPassReverse, and don't canonicalise URL passed to backend.
260 Documentation correspondingly updated. [Nick Kew <nick webthing.com>]
262 *) mod_deflate: support gzip flags in inflate_out_filter
263 [Nick Kew <nick webthing.com>]
265 *) Drop the ErrorHeader directive which turned out to be a misnomer.
266 Instead there's a new optional flag for the Header directive
267 ('always'), which keeps the former ErrorHeader functionality.
270 *) mod_deflate: Don't deflate responses with zero length
271 e.g. proxied 304's [Allan Edwards]
273 *) <IfModule> now recognizes the module identifier in addition to the
274 file name. PR 29003. [Edward Rudd <eddie omegaware.com>, André Malo]
276 *) mod_ssl: Add "SSLHonorCipherOrder" directive to enable the
277 OpenSSL 0.9.7 flag which uses the server's cipher order rather
278 than the client's. PR 28665.
279 [Jim Schneider <jschneid netilla.com>]
281 *) mod_ssl: Drop support for the CompatEnvVars argument to
282 SSLOptions, which was never actually implemented in 2.0.
285 *) Fix bug in mod_deflate that unconditionally sent deflate'd output
286 even when Accept-Encoding is not present. [Justin Erenkrantz]
288 *) Pass environment variables through to piped loggers and start
289 them via the shell, resolving regressions since 1.3. PR 28815
290 [Ken Coar, Jeff Trawick]
292 *) External rewrite map responses are no longer limited to 2048
295 *) Proxy server was deleting cookies that Apache had already
296 assigned if the origin server had set any cookies. PR 27023.
299 *) Removed old and unmaintained ap_add_named_module API and changed
300 the following APIs to return an error instead of hard exiting:
301 ap_add_module, ap_add_loaded_module, ap_setup_prelinked_modules,
302 and ap_process_resource_config. [André Malo]

335 directive (previously NetWare-only) to override default thread
336 stack size for threads which handle client connections. Required
337 for some third-party modules on platforms with small default
338 thread stack size. [Jeff Trawick]
340 *) minor mod_auth_basic and mod_auth_digest sync. mod_auth_basic
341 now populates r->user with the (possibly unauthenticated) user,
342 and mod_auth_digest returns 500 when a provider returns
346 *) The whole codebase was relicensed and is now available under
347 the Apache License, Version 2.0 (http://www.apache.org/licenses).

418 *) Switch to APR 1.0 API.
420 *) Major overhaul of mod_include's filter parser. The new parser code
421 is expected to be more robust and should catch all of the edge cases
422 that were not handled by the previous one. This includes a binary
423 incompatible change of mod_include's external API. [André Malo]
425 *) mod_rewrite: Allow forced mimetypes [T=...] to get expanded.
426 PR 14223. [André Malo]
428 *) mod_rewrite: Fix LA-U and LA-F lookups in directory context. Previously

476 the INCLUDE path to be defined properly.
477 PR 11310. [Geoff Thorpe <geoff geoffthorpe.net>]

481 *) Replace the APACHE_CHECK_SSL_TOOLKIT method with a cleaner one, using
482 autoconf tools (AC_CHECK_HEADER, AC_CHECK_LIB etc).
483 [Geoff Thorpe <geoff geoffthorpe.net>]
485 *) change directive name from 'compressionlevel' to 'deflatecompressionlevel'
486 [Ian Holsman, André Malo]
488 *) mod_negotiation: quality values are now parsed independent from

490 PR 17564. [André Malo]
492 *) Extend mod_negotiation to evaluate the environment variables
493 no-gzip and gzip-only-text/html the same way as mod_deflate does.
496 *) mod_rewrite: Fix some problems reporting errors with mapping
497 programs (RewriteMap prg:/something). [Jeff Trawick]
499 *) Return 413 if chunk-ext-header is too long rather than reading from
500 the truncated line. PR 15857. [Justin Erenkrantz]
502 *) Allow restart of httpd to occur even with syntax errors in the config
503 file. PR 16813. [Justin Erenkrantz]

517 *) Forward port of mod_actions' ability to handle arbitrary methods
518 with the Script directive. [André Malo]
520 *) Let suexec send a message to stderr, if it failed or its policy
521 was violated. This message appears in the error log and allows
522 for easier debugging. PR 5381, 7638, 8255, 10773. [André Malo]

540 *) Replace some of the mutex locking in the worker MPM with
541 atomic operations for higher concurrency. [Brian Pane]
543 *) Allow 'make depend' to work with non-GCC compilers.
546 *) If an httpd.conf has commented out AddModule directives,
547 apxs -i -a will add an un-commented AddModule directive for
548 the new module, which breaks the config.

577 directory is local only. Assumes, of course, that the required
578 files are in ./modules/foo, but makes it easier to statically
579 build/log "external" modules. [Jim Jagielski]
581 *) Util_ldap: Implemented the util_ldap_cache_getuserdn() API so that
582 ldap authorization only modules have access to the util_ldap

2254 *) mod_rewrite can now sets cookies in err_headers, uses the correct
2255 expiry date, and can now set the path as well
2256 PR 12132,12181,12172.
2257 [Ian Holsman / Rob Cromwell <apachechangelog robcromwell.com>]
2259 *) The content-length filter no longer tries to buffer up
2260 the entire output of a long-running request before sending
2261 anything to the client. [Brian Pane]
2263 *) Win32: Lower the default stack size from 1MB to 256K. This will
2264 allow around 8000 threads to be started per child process.
2265 'EDITBIN /STACK:size apache.exe' can be used to change this
2266 value directly in the apache.exe executable.
2269 *) Win32: Implement ThreadLimit directive in the Windows MPM.
2272 *) Remove CacheOn config directive since it is set but never checked.
2273 No sense wasting cycles on unused code. Besides, the only truly
2274 bug free code is deleted code. :) [Paul J. Reder]
2276 *) BufferLogs are now run-time enabled, and the log_config now has 2 new
2277 callbacks to allow a 3rd party module to actually do the writing of the

2316 *) mod_disk_cache works much better. This module should still
2317 be considered experimental. [Eric Prud'hommeaux]
2319 *) Performance improvement for keepalive requests: when setting
2320 aside a small file for potential concatenation with the next
2321 response on the connection, set aside the file descriptor rather
2322 than copying the file into the heap. [Brian Pane]
2324 *) Modified version check on openssl so that it finds the executable
2325 first and then performs a check of the version, only warning the
2326 user if they chose, or we selected, an old version of OpenSSL.
2327 This change also allows the code to work for non-openssl libraries
2328 selected via the --with-ssl=dir option, which can override the
2329 automated library check in any case. [Roy Fielding]
2331 Changes with Apache 2.0.40
2333 *) SECURITY: CAN-2002-0661 (cve.mitre.org)
2334 Close a very significant security hole that
2335 applies only to the Win32, OS2 and Netware platforms. Unix was not
2336 affected, Cygwin may be affected. Certain URIs will bypass security
2337 and allow users to invoke or access any file depending on the system
2338 configuration. Without upgrading, a single .conf change will close
2339 the vulnerability. Add the following directive in the global server
2340 httpd.conf context before any other Alias or Redirect directives;
2341 RedirectMatch 400 "\\\.\."
2342 Reported by Auriemma Luigi <bugtest sitoverde.com>.
2345 *) SECURITY: CAN-2002-0654 (cve.mitre.org)
2346 Close a path-revealing exposure in multiview type
2347 map negotiation (such as the default error documents) where the
2348 module would report the full path of the typemapped .var file when
2349 multiple documents or no documents could be served based on the mime
2350 negotiation. Reported by Auriemma Luigi <bugtest sitoverde.com>.
2353 *) SECURITY: CAN-2002-0654 (cve.mitre.org)
2354 Close a path-revealing exposure in cgi/cgid when we
2355 fail to invoke a script. The modules would report "couldn't create
2356 child process /path-to-script/script.pl" revealing the full path
2357 of the script. Reported by Jim Race <jrace qualys.com>.
2360 *) Set aside the apr-iconv and apr_xlate() features for the Win32
2361 build of 2.0.40 so development can be completed. A patch, from
2362 <http://www.apache.org/dist/httpd/patches/apply_to_2.0.40/>
2363 will be available for those that wish to work with apr-iconv.
2366 *) Fix proxy so that it is possible to access ftp: URLs via a proxy
2367 chain. [Peter Van Biesen <peter.vanbiesen vlafo.be>]
2369 *) mod-deflate now checks to make sure that 'gzip-only-text/html' is
2370 set to 1, so we can exclude things from the general case with
2371 browsermatch. [Ian Holsman, Andre Schild <A.Schild aarboard.ch>]
2373 *) Accept multiple leading /'s for requests within the DocumentRoot.
2374 PR 10946 [William Rowe, David Shane Holden <dpejesh yahoo.com>]
2376 *) Solved the reports of .pdf byterange failures on Win32 alone.
2377 APR's sendfile for the win32 platform collapses header and trailer
2378 buffers into a single buffer. However, we destroyed the pointers
2379 to the header buffer if a trailer buffer was present. PR 10781
2382 *) mod_ext_filter: Add the ability to enable or disable a filter via
2383 an environment variable. Add the ability to register a filter of
2384 type other than AP_FTYPE_RESOURCE. [Jeff Trawick]
2386 *) Restore the ability to specify host names on Listen directives.
2387 PR 11030. [Jeff Trawick, David Shane Holden <dpejesh yahoo.com>]
2389 *) When deciding on the default address family for listening sockets,
2390 make sure we can actually bind to an AF_INET6 socket before
2391 deciding that we should default to AF_INET6. This fixes a startup
2392 problem on certain levels of OpenUNIX. PR 10235. [Jeff Trawick]
2394 *) Replace usage of atol() to parse strings when we might want a
2395 larger-than-long value with apr_atoll(), which returns long long.
2396 This allows HTTPD to deal with larger files correctly.
2397 [Shantonu Sen <ssen apple.com>]
2399 *) mod_ext_filter: Ignore any content-type parameters when checking if
2400 the response should be filtered. Previously, "intype=text/html"
2401 wouldn't match something like "text/html;charset=8859_1".
2404 *) mod_ext_filter: Set up environment variables for external programs.
2405 [Craig Sebenik <craig netapp.com>]
2407 *) Modified the HTTP_IN filter to immediately append the EOS (end of
2408 stream) bucket for C-L POST bodies, saving a roundtrip and allowing
2409 the caller to determine that no content remains without prefetching
2410 additional POST body. [William Rowe]

2429 and MSVC now trust that the project is current (when it is).
2430 [James Cox <imajes php.net>]
2432 *) mod_ext_filter: don't segfault if content-type is not set. PR 10617.
2433 [Arthur P. Smith <apsmith aps.org>, Jeff Trawick]
2435 *) APR-Util Renames pending have been completed [Thom May]
2437 *) Performance improvements for the code that reads request
2438 headers (ap_rgetline_core() and related functions) [Brian Pane]
2440 *) Add a new directive: MaxMemFree. MaxMemFree makes it possible
2441 to configure the maximum amount of memory the allocators will
2442 hold on to for reuse. Anything over the MaxMemFree threshold
2443 will be free()d. This directive is useful when uncommon large
2444 peaks occur in memory usage. It should _not_ be used to mask
2445 defective modules' memory use. [Sander Striker]
2447 *) Fixed the Content-Length filter so that HTTP/1.0 requests to CGI
2448 scripts would not result in a truncated response.
2449 [Ryan Bloom, Justin Erenkrantz, Cliff Woolley]
2451 *) Add a filter_init parameter to the filter registration functions
2452 so that a filter can execute arbitrary code before the handlers
2453 are invoked. This resolves a problem where mod_include requests
2454 would incorrectly return a 304. [Justin Erenkrantz]
2456 *) Fix a long-standing bug in 2.0, CGI scripts were being called
2457 with relative paths instead of absolute paths. Apache 1.3 used
2458 absolute paths for everything except for SuExec, this brings back
2459 that standard. [Ryan Bloom]
2461 *) Fix infinite loop due to two HTTP_IN filters being present for
2462 internally redirected requests. PR 10146. [Justin Erenkrantz]
2464 *) Switch conn_rec->keepalive to an enumeration rather than a bitfield.
2467 *) Fix mod_ext_filter to look in the main server for filter definitions
2468 when running in a vhost if the filter definition is not found in
2469 the vhost. PR 10147 [Jeff Trawick]
2471 *) Support WinNT CGI invocation through ScriptInterpreterSource
2472 'registry' for script interpreter paths and names with non-ascii
2473 characters in the executable filepath. [William Rowe]
2475 *) Support the -w flag on to keep the Win32 console open on error.
2478 *) Normalize the hostname value in the request_rec to all-lowercase
2479 [Perry Harrington <pedward webcom.com>]
2481 *) Fix WinNT cgi 500 errors when QUERY_ARGS or other strings include
2482 extended characters (non US-ASCII) in non-utf8 format. This brings
2483 Win32 back into CGI/1.1 compliance, and leaves charset decoding up
2484 to the cgi application itself. [William Rowe]
2486 *) Major overhaul of mod_dav, mod_dav_fs and the experimental/cache
2487 modules to bring them up to the current apr/apr-util APIs.
2490 *) Fix segfault in mod_mem_cache most frequently observed when
2491 serving the same file to multiple clients on an MP machine.
2494 *) mod_rewrite can now set cookies (RewriteRule (.*) - [CO=name:$1:.domain])
2495 [Brian Degenhardt <bmd mp3.com>, Ian Holsman]
2497 *) Fix perchild to work with apachectl by adding -k support to perchild.
2498 PR 10074 [Jeff Trawick]
2500 *) Fix a silly htpasswd.c logic error that incorrectly reported that
2501 both -c and -n had been used. PR 9989 [Cliff Woolley]
2503 *) Fixed a mod_include error case in which no HTTP response was sent
2504 to the client if an shtml document contained an unterminated SSI
2505 directive [Brian Pane]
2507 *) Improve ap_get_client_block implementation by using APR-util brigade
2508 helper functions and relying on current filter assumptions.
2511 Changes with Apache 2.0.39
2513 *) Fixed a build problem in htpasswd.c on Win32.
2514 [Guenter Knauf <eflash gmx.net>, Cliff Woolley]
2516 Changes with Apache 2.0.38
2518 *) Rewrite htpasswd to use APR. The removes the annoying warning about
2519 tmpnam being unsafe. [Ryan Bloom]
2521 *) We must set the MIME-type for .shtml files to text/html if we want them
2522 to be parsed for SSI tags. Add the config for that to the default
2523 config file so that it is easier to enable .shtml parsing.
2524 [Dave Dyer <ddyer real-me.net>]
2526 *) Fixed a problem with 'make install' on ReliantUnix.
2527 [Jean-frederic Clere <jfrederic.clere fujitsu-siemens.com>]
2529 *) Make the default_handler catch all requests that aren't served by
2530 another handler. This also gets us to return a 404 if a directory
2531 is requested, there is no DirectoryIndex, and mod_autoindex isn't
2532 loaded. [Justin Erenkrantz]
2534 *) Fixed the handling of nested if-statements in shtml files.
2535 PR 9866 [Brian Pane]
2537 *) Allow 'make install DESTDIR=/path'. This allows packagers to install
2538 into a directory different from the one that was configured. This
2539 also mirrors the root= feature from 1.3. We cannot use prefix=,
2540 because both APR and APR-util resolve their installation paths at
2541 configuration time. This means that there is no variable prefix
2542 to replace. [Andreas Hasenack <andreas netbank.com.br>]
2544 *) AIX 4.3.2 and above: Define SINGLE_LISTEN_UNSERIALIZED_ACCEPT.
2545 These levels of AIX don't have a thundering herd problem with
2546 accept(). [Jeff Trawick]
2548 *) prefork MPM: Ignore mutex errors during graceful restart. For
2549 certain types of mutexes (particularly SysV semaphores), we
2550 should expect to occasionally fail to obtain or release the
2551 mutex during restart processing. [Jeff Trawick]
2553 *) Fix install-bindist.sh so that it finds any perl instead of just
2554 early perl 5.x versions. This is consistent with a build/install
2555 from source, and it allows the perl scripts installed by a bindist
2556 to work on systems with perl 5.6. [Jeff Trawick]
2558 *) Fix apxs so that the makefile created by "apxs -g" works on AIX and
2559 Tru64 (and probably some other platforms). [Jeff Trawick]
2561 *) Allow CGI scripts to return their Content-Length. This also fixes a
2562 hang on HEAD requests seen on certain platforms (such as FreeBSD).
2565 *) Added log rotation based on file size to the RotateLog support
2566 utility. [Brad Nicholes]
2568 *) Fix some casting in mod_rewrite which broke random maps.
2569 PR 9770 [Allan Edwards, Greg Ames, Jeff Trawick]
2571 Changes with Apache 2.0.37
2573 *) allow POST method over SSL when per-directory client cert
2574 authentication is used with 'SSLOptions +OptRenegotiate' enabled
2575 and a client cert was found in the ssl session cache.
2577 *) 'SSLOptions +OptRengotiate' will use client cert in from the ssl
2578 session cache when there is no cert chain in the cache. prior to
2579 the fix this situation would result in a FORBIDDEN response and
2580 error message "Cannot find peer certificate chain"
2583 *) ap_finalize_sub_req_protocol() shouldn't send an EOS bucket if
2584 one was already sent. PR 9644 [Jeff Trawick]
2586 *) Fix the display of the default name for the mime types config
2587 file. PR 9729 [Matthew Brecknell <mbrecknell orchestream.com>]

2591 of Apache.exe, in the case that Apache.exe resides in bin/.)
2592 Solves the case of ServerRoot /foo paths where /foo was not
2593 on the same drive as /winnt/system32. [William Rowe]
2595 *) Make 2.0's "AcceptMutex" startup message now "completely"
2596 match how 1.3 does it. [Jim Jagielski]
2598 *) Implement a fixed size memory cache using a priority queue
2601 *) Fix apxs to allow "apxs -q installbuilddir" and to allow
2602 querying certain other variables from config_vars.mk. PR 9316
2605 *) Added the "detached" attribute to the cgi_exec_info_t internals
2606 so that Win32 and Netware won't create a new window or console
2607 for each CGI invoked. PR 8387
2608 [Brad Nicholes, William Rowe]
2610 *) Consolidated the command line parameters and attributes that are
2611 manipulated by the optional function ap_cgi_build_command() in
2612 mod_cgi into a single structure.
2615 *) Get rid of uninitialized value errors with "apxs -q" on certain
2616 variables. [Stas Bekman <stas stason.org>]
2618 *) Fix apxs to allow it to work when the build directory is somewhere
2619 besides server-root/build. PR 8453
2620 [Jeff Trawick and a host of others]
2622 *) Allow ap_discard_request_body to be called multiple times in the
2623 same request. Essentially, ap_http_filter keeps track of whether
2624 it has sent an EOS bucket up the stack, if so, it will only ever
2625 send an EOS bucket for this request.
2626 [Ryan Bloom, Justin Erenkrantz, Greg Stein]
2628 *) Remove all special mod_ssl URIs. This also fixes the bug where
2629 redirecting (.*) will allow an SSL protected page to be viewed
2630 without SSL. [Ryan Bloom]
2632 *) Fix the binary build install script so that the build logic
2633 created by "apxs -g" will work when the user has a binary
2634 build. [Jeff Trawick]
2636 *) Allow instdso.sh to work with full paths to the shared module.
2639 *) NetWare: Enabled CGI functionality and added mod_cgi as a built
2640 in module for NetWare [Brad Nicholes]
2642 *) Changed cgi and piped log behavior to accept 65536 characters
2643 on Win32 (matching Linux) before deadlocking between outputing
2644 client stdin, slurping the output from stdout and then the stderr
2645 stream. PR 8179 [William Rowe]
2647 *) Fixed Win32 wintty.exe support to assure the window title is valid.
2648 Elimiates possible gpfault or garbage title without the -t option.
2651 *) Rewrite mod_cgi, mod_cgid, and mod_proxy input handling to use
2652 brigades and input filters. [Justin Erenkrantz]
2654 *) Allow ap_http_filter (HTTP_IN) to return EOS when there is no request
2655 body. [Justin Erenkrantz]
2657 *) NetWare: Piping log entries through RotateLogs using the
2658 CustomLogs directive is finally supported now that we have
2659 the pipes and spawning functionality working.

2674 *) Fix the TIME_* SSL var lookups to be threadsafe. PR 9469.
2677 *) Ensure that apr_brigade_write() flushes in all of the cases that
2678 it should to avoid conditions in some modules that could cause
2679 large amounts of data to be buffered. [Cliff Woolley]
2681 *) Fix problem where mod_cache/mod_disk_cache was incorrectly
2682 stripping the content_type from cached responses.
2685 *) apachectl passes through any httpd options. Note: apachectl
2686 should be used in preference to httpd since it ensures that any
2687 appropriate environment variables have been set up.

2734 of Apache. [Jeff Trawick]
2736 *) Removed documentation references to the no-longer-supported

2738 certificates, if truly desired, can be generated using openssl
2739 commands. PR 8724. [Cliff Woolley]
2741 *) Remove SSLLog and SSLLogLevel directives in favor of having
2742 mod_ssl use the standard ErrorLog directives. [Justin Erenkrantz]
2744 *) OS/390: LIBPATH no longer has to be manually uncommented in
2745 envvars to get apachectl to set up httpd properly. [Jeff Trawick]
2747 *) mod_isapi: All mod_isapi directives, excluding ISAPICacheFile,
2748 may now be specified to the <File/Directory > container, rather

2804 *) Allow mod_rewrite's set of "int:" internal RewriteMap functions
2805 to be extended by third-party modules via an optional function.

2817 *) Win32: During a graceful restart, threads in the new process
2818 were accessing scoreboard slots still in use by active threads in
2819 the old process. [Bill Stoddard]
2821 Changes with Apache 2.0.36
2823 *) Fix some minor formatting issues with ab. Part of this is
2824 in reference to PR 8544, the rest I noticed while testing
2825 the PR fix. [Paul J. Reder]
2827 *) Fix a case where an invalid pass phrase is entered and an
2828 error message is given, but the prompt is not shown again.
2829 This left the user in an ambiguous state. PR 8320 [Paul J. Reder]
2831 *) Close sockets on worker MPM when doing a graceless restart.
2834 *) Reverted a minor optimization in mod_ssl.c that used the vhost ID
2835 as the session id context rather that a MD5 hash of that vhost ID,
2836 because it caused very long vhost id's to be unusable with mod_ssl.
2837 PR 8572. [Cliff Woolley]
2839 *) Fix the link to the description of the CoredumpDirectory
2840 directive in the server-wide document. PR 8643. [Jeff Trawick]
2842 *) Fixed SHMCB session caching. [Aaron Bannert, Cliff Woolley]
2844 *) Synced with remaining changes from mod_ssl 2.8.8-1.3.24:
2845 - Avoid SIGBUS on sparc machines with SHMCB session caches
2846 - Allow whitespace between the pipe and the name of the
2847 program in SSLLog "| /path/to/program". [Cliff Woolley]
2849 *) Introduce mod_ext_filter and mod_deflate experimental modules
2850 to the Win32 build (zlib sources must be in srclib\zlib.)
2853 *) Changes to the worker MPM's queue management and thread
2854 synchronization code to reduce mutex contention [Brian Pane]
2856 *) Don't install *.in configuration files since we already install
2857 *-std.conf files. [Aaron Bannert]
2859 *) Many improvements to the threadpool MPM. [Aaron Bannert]
2861 *) Fix subreqs that are promoted via fast_redirect from having invalid
2862 frec->r structures. This would cause subtle errors later on in
2863 request processing such as seen in PR 7966. [Justin Erenkrantz]
2865 *) More efficient pool recycling logic for the worker MPM [Brian Pane]
2867 *) Modify the worker MPM to not accept() new connections until
2868 there is an available worker thread. This prevents queued
2869 connections from starving for processing time while long-running
2870 connections were hogging all the available threads. [Aaron Bannert]
2872 *) Convert the worker MPM's fdqueue from a LIFO back into a FIFO.
2875 *) Get basic HTTP proxy working on EBCDIC machines. [Jeff Trawick]
2877 *) Allow mod_unique_id to work on systems with no IPv4 address

2905 *) Swap downgrade-1.0 and force-response-1.0 conditional checks so
2906 that downgraded responses can have force-response. PR 8357.

2913 ap_uname2id. [Scott Lamb <slamb slamb.org>]
2915 *) Fix AcceptPathInfo. PR 8234 [Cliff Woolley]
2917 *) SECURITY: Added the APLOG_TOCLIENT flag to ap_log_rerror() to
2918 explicitly tell the server that warning messages should be sent
2919 to the client in addition to being recorded in the error log.
2920 Prior to this change, ap_log_rerror() always sent warning
2921 messages to the client. In one case, a faulty CGI script caused
2922 the server to send a warning message to the client that contained
2923 the full path to the CGI script. This could be considered a
2924 minor security exposure. [Bill Stoddard]
2926 *) mod_autoindex output when SuppressRules was specified would
2927 omit the first carriage return so the first item in the list
2928 would appear to the right of the column headings instead of
2929 underneath them. PR 8016 [David Shane Holden <dpejesh yahoo.com>]
2931 *) Moved the call to apr_mmap_dup outside the error branch so
2932 that it would actually get called. This fixes a core dump
2933 at init everytime you use the MMapFile directive. PR 8314
2936 *) Trigger an error when a LoadModule directive attempts to
2937 load a module which is built-in. This is a common error when
2938 switching from a DSO build to a static build. [Jeff Trawick]
2940 *) Change instdso.sh to use libtool --install everywhere and then
2941 clean up some stray files and symlinks that libtool leaves around
2942 on some platforms. This gets subversion building properly since
2943 it needed a re-link to be performed by libtool at install time,
2944 and the old instdso.sh logic to simply cp the DSO didn't handle
2945 that requirement. [Sander Striker]
2947 *) Allow VPATH builds to succeed when configured from an empty
2948 directory. [Thom May <thom planetarytramp.net>]
2950 *) Fix 'control reaches end of non-void function' warning in

2953 *) Perchild MPM is now correctly deemed as experimental and is now
2954 located in server/mpm/experimental. [Justin Erenkrantz]
2956 *) Fix segfault in mod_mem_cache when garabge collecting an expired
2957 cache entry. [Bill Stoddard]
2959 *) Introduced -E startup_logfile_name option to httpd to allow admins
2960 to begin logging errors immediately. This provides Win32 users
2961 an alternative to sending startup errors to the event viewer, and
2962 allows other daemon tool authors an alternative to logging to stderr.
2965 *) Fix subreqs with non-defined Content-Types being served improperly.
2968 *) Merge in latest GNU config.guess and config.sub files. PR 7818.

3000 *) Win32: Fix problem that caused rapid performance degradation
3001 when number of connecting clients exceeded ThreadsPerChild.
3004 *) Fixed a segfault parsing large SSIs on non-mmap systems.
3007 *) Proxy was bombing out every second keepalive request, caused by a
3008 stray CRLF before the second response's status line. Proxy now
3009 tries to read one more line if it encounters a CRLF where it
3010 expected a status. PR 10010 [Graham Leggett]
3012 *) Deprecated the apr_lock.h API. Please see the following files
3013 for the improved thread and process locking and signaling:
3014 apr_proc_mutex.h, apr_thread_mutex.h, apr_thread_rwlock.h,
3015 apr_thread_cond.h, and apr_global_mutex.h. [Aaron Bannert]
3017 *) Change mod_status to use scoreboard accessor functions so it can
3018 be used in any MPM without having to be recompiled.
3019 [Ryan Morgan <rmorgan covalent.net>]
3021 *) Fix parsing of some AP_DECLARE_DATA declarations so that the filter

3042 Changes with Apache 2.0.35
3044 *) mod_rewrite: updated to use the new APR global mutex type.
3047 *) Fixes for mod_include errors on boundary conditions in which
3048 "<!--#" occurs at the very end of a bucket
3049 [Paul Reder, Brian Pane]
3051 *) worker, prefork, perchild, beos MPMs: Add -DFOREGROUND switch to
3052 cause the Apache parent process to run in the foreground (similar to
3053 -DNO_DETACH except that it doesn't switch session ids).
3056 *) Added support for Posix semaphore mutex locking (AcceptMutex posixsem)
3057 for those platforms that support it. If using the default
3058 implementation, this is between pthread and sysvsem in priority.
3059 This implies it's the new default for Darwin. [Jim Jagielski]
3061 *) AIX: Fix the syntax for setting the LDR_CNTRL and AIXTHREAD_SCOPE
3062 environment variables in the envvars file. [Jeff Trawick]
3064 *) worker MPM: Don't create a listener thread until we have a worker
3065 thread. Otherwise, in situations where we'll have to wait a while
3066 to take over scoreboard slots from a previous generation, we'll be
3067 accepting connections we can't process yet. [Jeff Trawick]
3069 *) Allow worker MPM to build on systems without pthread_kill().
3070 [Pier Fumagalli, Jeff Trawick]
3072 *) Prevent ap_add_output_filters_by_type from being called in
3073 ap_set_content_type if the content-type hasn't changed.
3076 *) Performance: implemented the bucket allocator made possible by the
3077 API change in 2.0.34. [Cliff Woolley]
3079 *) Don't allow initialization to succeed if we can't get a socket
3080 corresponding to one of the Listen statements. [Jeff Trawick]
3082 Changes with Apache 2.0.34
3084 *) Allow all Perchild directives to accept either numerical UID/GID
3085 or logical user/group names. [Scott Lamb <slamb slamb.org>]

3089 *) implement ssl proxy to support ProxyPass / https:// and the
3090 SSLProxy* directives [Doug MacEachern]

3095 *) Made AB's use of the Host: header rfc2616 compliant
3096 by Taisuke Yamada <tai iij.ad.jp> [Dirk-Willem van Gulik].
3098 *) The old, legacy (and unused) code in which the scoreboard was totally
3099 and completely contained in a file (SCOREBOARD_FILE) has been
3100 removed. This does not affect scoreboards which are *mapped* to
3101 files using named-shared-memory. [Jim Jagielski]
3103 *) Change bucket brigades API to allow a "bucket allocator" to be
3104 passed in at certain points. This allows us to implement freelists
3105 so that we can stop using malloc/free so frequently.
3106 [Cliff Woolley, Brian Pane]
3108 *) Add support for macro expansion within the variable names in
3109 <!--#echo--> and <!--#set--> directives [Brian Pane]
3111 *) Fix some mod_include segfaults [Cliff Woolley, Brian Pane, Brad Nicholes]
3113 *) Update the "RedHat" Layout to match Red Hat Linux version 7. PR BZ-7422
3116 *) add compat layer to support RSA SSLC 1.x and 2.x in mod_ssl

3119 *) Add a new parameter to the quick_handler hook to instruct
3120 quick handlers to optionally do a lookup rather than actually
3121 serve content. This is the first of several changes required fix
3122 several problems with how quick handlers work with subrequests.
3125 *) worker MPM: Get MaxRequestsPerChild to work again. [Jeff Trawick]
3127 *) [APR-related] The ordering of the default accept mutex method has
3128 been changed to better match what's done in Apache 1.3. The ordering
3129 is now (highest to lowest): pthread -> sysvsem -> fcntl -> flock.
3132 *) Ensure that the build/ directory is created when using VPATH.
3135 *) Add some popular types to the mime magic file. PR 7730.
3136 [Linus Walleij <triad df.lth.se>, Justin Erenkrantz]
3138 *) Remove the single-byte socket reads for CGI headers [Brian Pane]
3140 *) When a proxied site was being served, Apache was replacing
3141 the original site Server header with it's own, which is not
3142 allowed by RFC2616. Fixed. [Graham Leggett]
3144 *) Fix a mod_cgid problem that left daemon processes stranded
3145 in some server restart scenarios. [Jeff Trawick]
3147 *) Added exp_foo and rel_foo variables to config_vars.mk for
3148 all Apache and Autoconf path variables (like --sysconfdir,
3149 --sbindir, etc). exp_foo is the "expanded" version, which means
3150 that all internal variable references have been interpolated.
3151 rel_foo is the same as $exp_foo, only relative to $prefix if they
3152 share a common path. [Aaron Bannert]
3154 *) Fix some restart/terminate problems in the worker MPM. Don't
3155 drop connections during graceful restart. [Jeff Trawick]
3157 *) Change the header merging behaviour in proxy, as some headers
3158 (like Set-Cookie) cannot be unmerged due to stray commas in
3159 dates. [Graham Leggett]
3161 *) Be more vocal about what AcceptMutex values we allow, to make
3162 us closer to how 1.3 does it. [Jim Jagielski]

3167 *) Upgraded PCRE library to latest version 3.9 [Brian Pane]
3169 *) Add accessor function to set r->content_type. From now on,
3170 ap_rset_content_type() should be used to set r->content_type.
3171 This change is required to properly implement the
3172 AddOutputFilterByType configuration directive.
3173 [Bill Stoddard, Sander Striker, Ryan Bloom]

3181 *) Fix for virtual host processing where the requested hostname
3182 has a '.' at the end (PR 9187) [Ryan Cruse <ryan estara.com>]
3184 *) mod_dav's APIs for REPORT response handling was changed so that
3185 providers can generate the content directly into the output filter
3186 stack, rather than buffering the response into memory. [Greg Stein]
3188 *) Fix a hang condition with graceful restart and prefork MPM
3189 in the situation where MaxClients is very high but
3190 much fewer servers are actually started at the time of the
3191 restart. [Jeff Trawick]
3193 *) Small performance fixes for mod_include [Brian Pane]
3195 *) Performance improvement for the error logger [Brian Pane]
3197 *) Change configure so that Solaris 8 and above have
3198 SINGLE_LISTEN_UNSERIALIZED_ACCEPT defined by default.
3199 according to sun people solaris 8+ doesn't have a thundering
3200 herd problem [Ian Holsman]
3202 *) Allow URIs specifying CGI scripts to include '/' at the end

3221 *) Use apr_atomic operations in managing the mod_mem_cache
3222 cache_objects for SMP scalability. (see USE_ATOMICS
3223 preprocessor directive in mod_file_cache)
3226 *) Add filehandle caching to mod_mem_cache. (see CACHE_FD
3227 preprocessor directive in mod_file_cache)
3230 *) Implement prototype mod_disk_cache for use with mod_cache.
3233 *) Add a missing manualdir entry in the Debian config.layout.
3234 [Thom May <thom planetarytramp.net>]
3236 *) Stop installing libtool for APR and tell APR where it should place
3237 its copy of libtool (via our installbuildpath layout variable).
3240 *) New directive ProxyIOBufferSize. Sets the size of the buffer used
3241 when reading from a remote HTTP server in proxy. [Graham Leggett]
3243 *) Modify receive/send loop in proxy_http and proxy_ftp so that
3244 should it be necessary, the remote server socket is closed before
3245 transmitting the last buffer (set by ProxyIOBufferSize) to the
3246 client. This prevents the backend server from being forced to hang
3247 around while the last few bytes are transmitted to a slow client.
3248 Fix the case where no error checking was performed on the final
3249 brigade in the loop. [Graham Leggett]
3251 *) Scrap CacheMaxExpireMin and CacheDefaultExpireMin. Change
3252 CacheMaxExpire and CacheDefaultExpire to use seconds rather than
3253 hours. [Graham Leggett, Bill Stoddard]
3255 *) New Directive SSIUndefinedEcho. to change the '(none)' echoed
3256 for a undefined variable. [Ian Holsman]
3258 *) Proxy HTTP and CONNECT: Keep trying other addresses from the DNS
3259 when we can't get a socket in the specified address family. We may
3260 have gotten back an IPv6 address first and yet our system is not
3261 configured to allow IPv6 sockets. [Jeff Trawick]
3263 *) Be more careful about recursively removing CVS directories. Make
3264 sure that we aren't cd'ing to their home directory first. PR: 9993

3268 [Dirk-Jan Faber <dirk-jan selwerd.nl>, Aaron Bannert,
3269 Thom May <thom planetarytramp.net>]
3271 *) Rename the filter ordering priorities. The recent filtering fixes
3272 have showcased problems with their usage. Therefore, we need to
3273 rename them to increase the clarity. (CONTENT->RESOURCE,
3274 HTTP_HEADER->CONTENT_SET/PROTOCOL) [Justin Erenkrantz]
3276 Changes with Apache 2.0.33
3278 *) Fix a problem in the new --enable-layout functionality where
3279 it wouldn't allow overrides from variables like --prefix,
3280 --bindir, etc. [Thom May <thom planetarytramp.net>]
3282 *) Fix a bug in the core input filter for AP_MODE_EXHAUSTIVE. It
3283 no longer hangs around waiting for the socket to close before
3284 returning exhaustive data. [Aaron Bannert]
3286 *) rename apr_exploded_time_t to apr_time_exp_t (as per renames pending)
3287 [Thom May <thom planetarytramp.net>]
3289 *) Change mod_ssl to always do a full startup/teardown on restarts.
3290 this allows mod_ssl to be added to a server that is already
3291 running and makes it possible to add/change certs/keys after the
3292 server has been started. [Doug MacEachern]
3294 *) Introduce PassPhraseDialog "|/path/to/pipe" mechanism to mod_ssl.
3295 This pipe must be a bidirectional 'console' style relay, which
3296 mod_ssl prints all prompts to the pipe's stdin, and reads the
3297 passphrases from the pipe's stdout. [William Rowe]
3299 *) Fix bug where --sysconfdir and --localstatedir were being
3300 ignored. [Thom May <thom planetarytramp.net>, Aaron Bannert]
3303 *) Fix --enable-layout to work again. Caution: When specifying
3304 --enable-layout, common arguments like --prefix, --exec-prefix,
3305 etc. will be ignored and the settings from the layout will be
3306 used instead. [Thom May <thom planetarytramp.net>, Aaron Bannert]
3309 *) New Directive for mod_proxy: ProxyRemoteMatch. This provides
3310 regex pattern matching for the determination of which requests
3311 to use the remote proxy for. [Jim Jagielski]
3313 *) Fix CustomLog bytes-sent with HTTP 0.9. [Justin Erenkrantz]
3315 *) Prevent Apache from ignoring SIGHUP due to some lingering 1.3
3316 cruft in piped logs and rewritemap child processes.
3319 *) All instances of apr_lock_t have been removed and converted
3320 to one of the following new lock APIs: apr_thread_mutex.h,
3321 apr_proc_mutex.h, or apr_global_mutex.h. No new code should
3322 use the apr_lock.h API, as the old API will soon be deprecated.
3325 *) Merged in changes to mod_ssl up through 2.8.7-1.3.23.
3326 [Ralf S. Engelschall, Cliff Woolley]
3328 *) mod-include: make it handle flush'es and fix the 'false-alarm'
3329 [Justin Erenkrantz, Brian Pane, Ian Holsman]
3331 *) ap_get_*_filter_handle() functions to allow 3rd party modules
3332 to lookup filter handles so they can bypass the filter name
3333 lookup when adding filters to a request (via ap_add_*_filter_handle())
3334 [Ryan Morgan <rmorgan covalent.net>]
3336 *) Fix for multiple file buckets on Win32, where the first file
3337 bucket would cause the immediate closure of the socket on any
3338 non-keepalive requests. [Ryan Morgan <rmorgan covalent.net>]
3340 *) Correct Win32 failure of mmap of a segment beyond start of the
3341 file; fixes large SSL and similar transfers. [William Rowe]
3344 *) Implement apr_proc_detach changes and allow -DNO_DETACH in the
3345 multi-process mode to not "daemonize" while detaching from the
3346 controlling terminal. This is necessary for Apache to work with
3347 process-management tools like AIX's "System Resource Controller"
3348 as well as Dan Bernstein's "daemontools".
3349 [Jos Backus <josb cncdsl.com>, Aaron Bannert]
3351 *) Convert mod_auth_digest to use the new apr_global_mutex_t
3352 type. [Aaron Bannert]
3354 *) fix bug in mod-include where it wouldn't send a unmatched
3355 part if it was at the end of a bucket [Ian Holsman]
3357 *) worker MPM: Improve logging of errors with the interface between
3358 the listener thread and worker threads. [Jeff Trawick]
3360 *) Some browsers ignore cookies that have been merged into a
3361 single Set-Cookie header. Set-Cookie and Set-Cookie2 headers
3362 are now unmerged in the http proxy before being sent to the
3363 client. [Graham Leggett]
3365 *) Fix a problem with proxy where each entry of a duplicated
3366 header such as Set-Cookie would overwrite and obliterate the
3367 previous value of the header, resulting in multiple header
3368 values (like cookies) going missing.
3369 [Graham Leggett, Joshua Slive]
3371 *) Add the server-limit and thread-limit values to the scoreboard

3375 *) Fix segfault when proxy recieves an invalid HTTP response [Ian Holsman]
3377 *) OS/390: Get make install to properly copy DSO modules.
3380 *) Win32: Fix bug in mod_status with displaying "Restart Time"
3381 and "Server uptime".
3384 *) Fix IPv6 name-based virtual hosts. [Jeff Trawick]
3386 *) Introduce AddOutputFilterByType directive. [Justin Erenkrantz]
3388 *) Fix DEBUG_CGI support in mod_cgi. PR 9670, 9671.
3389 [David MacKenzie <djm pix.net>]
3391 *) Fix incorrect check for script_in in mod_cgi. PR 9669.
3392 [David MacKenzie <djm pix.net>]
3394 *) Fix segfault and display error when SSLMutex file can not be
3395 created. [Adam Sussman <myddryn vishnu.vidya.com>]
3397 *) Add reference counting to mod_mem_cache cache objects to
3398 better manage removing objects from the cache.
3401 *) Change the verbage on the ScoreBoardFile in our default configs.
3402 Also change the default to be commented out (unspecified) so we
3403 get anonymous shared memory by default. [Aaron Bannert]
3405 *) Implement new ScoreBoardFile directive logic. This affects how
3406 we create the scoreboard's shared memory segment. If the directive
3407 is present, a name-based segment is created. If the directive is
3408 not present, first an anonymous segment is created, and if that
3409 fails, a name-based segment is created from a file of the name
3410 DEFAULT_SCOREBOARD. This gives third-party applications the
3411 ability to access our scoreboard. [Aaron Bannert]
3413 *) Allow mod_deflate to work with non-GET requests and properly send
3414 Content-Lengths. [Sander Striker <striker apache.org>]
3416 *) Fix ap_directory_merge() to correctly merge configs when there is
3417 no <Directory /> block. [Justin Erenkrantz, William Rowe]
3419 *) Remove spurious debug messsages that are normal under HTTP
3420 keep-alive logic. [Jeff Trawick, Justin Erenkrantz]
3422 *) Fix a bug in mod_cgid that would prevent proper shutdown death
3423 of the cgid process. [Aaron Bannert]
3425 *) Add signal handling back in to the worker MPM for the one_process
3426 (-X, -DDEBUG, -DONE_PROCESS) case. [Aaron Bannert]
3428 *) Performance: Reuse per-connection transaction pools in the
3429 worker MPM, rather than destroying and recreating them. [Brian Pane]
3431 *) Remove all signals from the worker MPM's child process. Instead,
3432 the parent uses the Pipe of Death for all communication with the
3433 child processes. [Ryan Bloom]
3435 Changes with Apache 2.0.32
3437 *) mod_negotiation: ForceLanguagePriority now uses 'Prefer' as the
3438 default if the directive is not specified. This mirrors older
3439 behavior without changes to the httpd.conf. [William Rowe]
3441 *) Win32: solve the win32 service problems in 2.0.31-alpha, by fixing
3442 the service, mpm and logging code, and bugs in apr_file_open_stderr
3443 and apr_file_dup2 functions. Win2K/XP services have no handles
3444 associated for stdin/out/err, which caused unpredictable behavior
3445 in the prior release. [William Rowe, Bill Stoddard]
3447 *) Win32: simplify the Application Event Log messages, since there isn't
3448 likely to be 'more information in the error log' before an error log
3449 has been opened. [William Rowe]
3451 *) Win32: substantial cleanup to the mpm_winnt code for legibility and
3452 to follow the program flow of other MPMs. [Ryan Bloom, William Rowe]
3454 *) Win32: apache -k shutdown now behaves like apache -k stop.
3457 *) Fix prefork to not kill the parent if a child hits a resource shortage
3458 on accept(). [Greg Ames]
3460 *) Fix seg faults that occur when what should be the httpd request line
3461 starts with \r\n followed by garbage. [Greg Ames]
3463 *) Allow statically linked support binaries with the new
3464 --enable-static-support flag, and enable this behavior in
3465 the binbuild script. Also add a new --enable-static-htdbm
3466 flag. [Aaron Bannert]
3468 *) Allow mod_autoindex to serve symlinks if permitted and attempt to
3469 do only one stat() call when generating the directory listings.
3472 *) Fix resolve_symlink to save the original symlink name if known.
3475 *) Be a bit more sane with regard to CanonicalNames. If the user has
3476 specified they want to use the CanonicalName, but they have not
3477 configured a port with the ServerName, then use the same port that
3478 the original request used. [Ryan Bloom and Ken Coar]
3480 *) In core_input_filter, check for an empty brigade after
3481 APR_BRIGADE_NORMALIZE(). Otherwise, we can get segfaults if a
3482 client says it will post some data but we get FIN before any
3483 data arrives. [Jeff Trawick]
3485 *) Not being able to bind to the socket is a fatal error. We should
3486 print an error to the console, and return a non-zero status code.
3487 With these changes, all of the Unix MPMs do that correctly.
3490 *) suexec: Allow HTTPS and SSL_* environment variables to be passed
3491 through to CGI scripts. PR 9163
3492 [Brian Reid <breid customlogic.com>,
3493 Zvi Har'El <rl math.technion.ac.il>]
3495 *) binbuild.sh: Make sure that we use the expat from our source
3496 tree so that there aren't any surprises on the target machine.
3499 *) mod_cgid: Add retry logic for when the daemon can't fork fast
3500 enough to keep up with new requests. Start using
3501 HTTP_SERVER_UNAVAILABLE instead of HTTP_INTERNAL_SERVER_ERROR
3502 when we can't talk to the daemon. [Jeff Trawick]
3504 *) apxs: LTFLAGS envvar can override default libtool options. Try
3505 "LTFLAGS=' ' apxs -c mod_foo.c" to see what libtool does under
3506 the covers. [Jeff Trawick]
3508 *) The Location: response header field, used for external
3509 redirect, *must* be an absoluteURI. The Redirect directive
3510 tested for that, but RedirectMatch didn't -- it would allow
3511 almost anything through. Now it will try to turn an abs_path
3512 into an absoluteURI, but it will correctly varf like Redirect
3513 if the final redirection target isn't an absoluteURI. [Ken Coar]
3515 Changes with Apache 2.0.31
3517 *) Create the scoreboard (in the parent) in a global pool context,
3518 so it survives graceful restarts. This fixes a SEGV during
3519 graceful restarts. [Aaron Bannert]
3521 *) Add a timeout option to the proxy code 'ProxyTimeout'
3524 *) FTP directory listings are now always retrieved in ASCII mode.
3525 The FTP proxy properly escapes URI's and HTML in the generated
3526 listing, and escapes the path components when talking to the FTP
3527 server. It is now possible to browse the root directory by using
3528 a url like: ftp://user@host/%2f/ (ported from apache_1.3.24)
3529 Also, the last path component may contain wildcard characters
3530 '*' and '?', and if they do, a directory listing is created instead
3531 of a file retrieval. Example: ftp://user@host/httpd/server/*.c
3534 *) Added single-listener unserialized accept support to the
3535 worker MPM [Brian Pane]
3537 *) New Directive for mod_proxy: 'ProxyPreserveHost'. This passes
3538 the incoming host header through to the proxied server
3539 [Geoff <g.russell ieee.org>]
3541 *) New Directive Option for ProxyPass. It now can block a location
3542 from being proxied [Jukka Pihl <jukka.pihl entirem.com>]
3544 *) Don't let the default handler try to serve a raw directory. At
3545 best you get gibberish. Much worse things can happen depending
3546 on the OS. [Jeff Trawick]
3548 *) Change the pre_config hook to return a value. Modules can now emit
3549 an error message and then cause the server to quit gracefully during
3550 startup. This required a bump to the MMN. [Aaron Bannert]
3552 *) Fix some unix socket descriptor leaks in the handler side of
3553 mod_cgid (the part that runs in the server process). Whack a
3554 silly "close(-1)" in the handler too. [Jeff Trawick]
3556 *) Change the pre_mpm hook to return a value, so that scoreboard
3557 init errors percolate up to code that knows how to exit
3558 cleanly. This required a bump to the MMN. [Jeff Trawick]
3560 *) Add the socket back to the conn_rec and remove the create_connection
3561 hook. The create_connection hook had a design flaw that did not
3562 allow creating connections based on vhost info. [Bill Stoddard]
3564 *) Fixed PATH_INFO and QUERY_STRING from mod_negotiation results.
3565 Resolves the common case of using negotation to resolve the request
3566 /script/foo for /script.cgi/foo. [William Rowe]
3568 *) Added new functions ap_add_(input|output)_filter_handle to
3569 allow modules to bypass the usual filter name lookup when
3570 adding hard-coded filters to a request [Brian Pane]
3572 *) caching should now work on subrequests (still very experimental)
3575 *) The Win32 mpm_winnt now has a shared scoreboard. [William Rowe]
3577 *) Change ap_get_brigade prototype to use apr_off_t instead of apr_off_t*.
3580 *) Refactor ap_rgetline so that it does not use an internal brigade.
3581 Change ap_rgetline's prototype to return errors. [Justin Erenkrantz]
3583 *) Remove mod_auth_db. [Justin Erenkrantz]
3585 *) Do not install unnecessary pcre headers like config.h and internal.h.
3586 [Joe Orton <joe manyfish.co.uk>]
3588 *) Change in quick_hanlder behavior for subrequests. it now passes DONE
3589 (as it does for a normal request). quick_handled sub-requests now work
3590 in mod-include [Ian Holsman]
3592 *) Change SUBREQ_CORE so that it is a 'HTTP_HEADER' filter instead of
3593 'CONTENT' one, as it needs to run AFTER all content headers
3595 *) Rename BeOS MPM directive RequestsPerThread to MaxRequestsPerThread.
3598 *) Split out blocking from the mode in the input filters.
3601 *) Fix a segfault in mod_include. [Justin Erenkrantz, Jeff Trawick]
3603 *) Cause Win32 to capture all child-worker process errors in
3604 Apache to the main server error log, until the child can
3605 open its own error logs. [William Rowe]
3607 *) HPUX 11.*: Do not kill the child process when accept()
3608 returns ENOBUFS on HPUX 11.*. (ported from th 1.3 patch)
3609 [Madhusudan Mathihalli <madhusudan_mathihalli hp.com>, Bill Stoddard]
3611 *) Fix a problem in the parsing of the <Proxy foo> directive.
3614 *) rewrite of mod_ssl input filter for better performance and less
3615 memory usage [Doug MacEachern]
3617 *) allow quick_handler to be run on subrequests. [Ian Holsman]
3619 *) mod_dav now asks its provider to place content directly into the
3620 filter stack when handling a GET request. The mod_dav/provider
3621 API has changed, so providers need to be updated. [Greg Stein]
3623 *) Clear the output socket descriptor in unixd_accept() to make sure
3624 we don't supply a bogus socket to the caller if the accept fails.
3625 This caused problems with the worker MPM, which tried to process
3626 the returned socket if it was non-NULL. [Brian Pane]
3628 *) Move a check for an empty brigade to the start of core input filter
3629 to avoid segfaults. [Justin Erenkrantz, Jeff Trawick]
3631 *) Add FileETag directive to allow configurable control of what
3632 data are used to form ETag values for file-based URIs. MMN
3633 bumped to 20020111 because of fields added to the end of
3634 the core_dir_config structure. [Ken Coar]
3636 *) Fix a segfault in mod_rewrite's logging code caused by passing the
3637 wrong config to ap_get_remote_host(). [Jeff Trawick]
3639 *) Allow mod_cgid to work from a binary distribution install by
3640 using 755 for the permissions on the log directory instead of
3643 *) Fixed a segfault that happened during graceful shutdown (or when
3644 the httpd ran out of file descriptors) with the worker MPM [Brian Pane]
3646 *) Split all Win32 modules [excluding the core components mod_core,
3647 mod_so, mod_win32 and the winnt mpm] into individual loadable
3648 modules, so the administrator may individually disable the former
3649 compiled-in modules by simply commenting out their LoadModule
3650 directives. [William Rowe]
3652 *) Saved Win32 module authors and porters many future headaches, by
3653 duplicating the appropriate .h files such as os.h into the include
3654 directory, including in the build tree. [William Rowe]
3656 *) mod_ssl adjustments to help with using toolkits other than OpenSSL:
3657 Use SSL functions/macros instead of directly dereferencing SSL
3658 structures wherever possible.
3659 Add type-casts for the cases where functions return a generic pointer.
3660 Add $SSL/include to configure search path.
3661 [Madhusudan Mathihalli <madhusudan_mathihalli hp.com>]
3663 *) Moved several pointers out of the shared Scoreboard so it is
3664 more portable, and will present the vhost name across server
3665 generation restarts. [William Rowe]
3667 *) Fix SSLPassPhraseDialog exec: and SSLRandomSeed exec:
3670 Changes with Apache 2.0.30
3672 *) Fix the main bug for FreeBSD and threaded MPM's. There are
3673 still issues (see STATUS) but at least the server will now
3674 run without crashing the machine.
3675 [David Reid, Aaron Bannert, Justin Erenkrantz]
3677 *) Fix a typo in mod_deflate's m4 config section.
3678 [albert chin <china thewrittenword.com>]
3680 *) Fix a couple of mod_proxy problems forwarding HTTP connections
3681 and handling CONNECT:
3682 (1) PR #9190 Proxy failed to connect to IPv6 hosts.
3683 (2) Proxy failed to connect when the first IP address returned by
3684 the resolver was unreachable but a secondary IP address was.
3687 *) Fix the module identifer as shown in the docs for various core
3688 modules (e.g., the identifer for mod_log_config was previously
3689 listed as config_log_module). PR #9338
3690 [James Watson <ap2bug sowega.org>]
3692 *) Fix LimitRequestBody directive by placing it in the HTTP
3693 filter. [Justin Erenkrantz]
3695 *) Fix mod_proxy seg fault when the proxied server returns
3696 an HTTP/0.9 response or a bogus status line.
3699 *) Prevent mod_proxy from truncating one character off the
3700 end of the status line returned from the proxied server.
3701 [Adam Sussman, Bill Stoddard]
3703 *) Eliminate loop in ap_proxy_string_read().
3704 [Adam Sussman, Bill Stoddard]
3706 *) Provide $0..$9 results from mod_include regex parsing.
3709 *) Allow mod-include to look for alternate start & end tags [Ian Holsman]
3711 *) Introduced the ForceLanguagePriority directive, to prevent
3712 returning MULTIPLE_CHOICES or NONE_ACCEPTABLE in some cases,
3713 when using Multiviews. [William Rowe]
3715 *) Fix a problem which prevented mod_cgid and suexec from working
3716 together reliably [Greg Ames]
3718 *) Remove the call to exit() from within mod_auth_digest's post_config
3719 phase. [Aaron Bannert]
3721 *) Fix a problem in mod_auth_digest that could potentially cause
3722 problems with initialized static data on a system that uses DSOs.
3725 *) Fix a segfault in the worker MPM that could happen during
3726 child process exits. [Brian Pane, Aaron Bannert]
3728 *) Allow mod_auth_dbm to handle multiple DBM types [Ian Holsman]
3730 *) Fix matching of vhosts by ip address so we find IPv4
3731 vhost address when target address is v4-mapped form of
3732 that address. [Jeff Trawick]
3734 *) More performance tweaks to the BNDM string-search algorithm
3735 used to find "<!--#" tokens in mod_include [Brian Pane]
3737 *) Miscellaneous small performance fixes: optimized away various
3738 string copy operations and removed large temp buffers from
3739 the stack [Brian Pane]
3741 *) Fixed startup segfault that occurred when a VirtualHost
3742 directive had a port but no address [Brian Pane]
3744 *) Allow htdbm to work with multiple DBM types [Ian Holsman]
3746 *) Win32: Made change to apr_sendfile() to return APR_ENOTIMPL
3747 if oslevel < WINNT. This should fix several problems reported
3748 Against 2.0.28 on Windows 98 [Bill Stoddard]
3750 *) Win32: Fix bug that could cause CGI scripts with QUERY_STRINGS
3751 to fail. [Bill Stoddard]
3753 *) Change core code to allow an MPM to set hard thread/server
3754 limits at startup. prefork, worker, and perchild MPMs now have
3755 directives to set these limits. [Jeff Trawick]
3757 *) Win32: The async AcceptEx() event should be autoreset upon
3758 successful completion of a wait (WaitForSingleObject). This
3759 eliminates a number of spurious
3760 setsockopt(SO_UPDATE_ACCEPT_CONTEXT) failed." messages.
3763 *) Move any load library path environment variables out of
3764 apachectl and into a separate environment variable file which
3765 can be more easily tailored by the admin. The environment
3766 variable file as built by Apache may have additional system-
3767 specific settings. For example, on OS/390 we tailor the heap
3768 settings to allow lots of threads. [Jeff Trawick]
3770 *) Use the new APR pool code to reduce pool-related lock
3771 contention in the worker MPM. [Sander Striker]
3773 *) The POD no longer assumes the child is listening on 127.0.0.1
3774 and now pulls the first hostname in the list of listeners to
3775 perform the dummy connect on. This fixes a bug when the user
3776 had configured the Listen directive for an IP other than
3777 127.0.0.1. This would result in undead children and error
3778 messages such as "Connection refused: connect to listener".
3781 *) The worker MPM now respects the LockFile setting, needed to
3782 avoid locking problems with NFS. [Jeff Trawick]
3784 *) Fix segfault when worker MPM receives SIGHUP.
3785 [Ian Holsman, Aaron Bannert, Justin Erenkrantz]
3787 *) Fix bug that could potentially prevent the perchild MPM from
3788 working with more than one vhost/uid. [Aaron Bannert]
3790 *) Change make install and apxs -i processing of DSO modules to
3791 perform special handling on platforms where libtool doesn't install
3792 mod_foo.so. This fixes some wonkiness on HP-UX, Tru64, and AIX
3793 which prevented standard LoadModule statements from working.
3796 *) Whenever mod_so is enabled (not just when there are DSOs for
3797 our modules), do whatever special magic is required for compiling/
3798 loading third-party modules. This allows third-party DSOs to
3799 be used on an AIX build when there were no built-in modules
3800 built as DSOs. (This should help on OS/390 and BeOS as well.)
3803 *) Allow apxs to be used to build DSOs on AIX without requiring the
3804 user to hard-code the list of import files. (This should help
3805 on OS/390 and BeOS as well.) [Jeff Trawick]
3807 *) Resolved segfault in mod_isapi when configuring with ISAPICacheFile.
3808 PR 8563, 8919 [William Rowe]
3810 *) Get binary builds working when libapr and libaprutil are built
3813 *) Get shared builds of libapr and libaprutil, as well as Apache DSOs,
3814 working on AIX. [Aaron Bannert, Dick Dunbar <RLDunbar pacbell.net>,
3815 Gary Hook <ghook us.ibm.com>, Victor Orlikowski, Jeff Trawick]
3817 *) Fix the handling of SSI directives in which the ">" of the
3818 terminating "-->" is the last byte in a file [Brian Pane]
3820 *) Add back in the "suEXEC mechanism enabled (wrapper: /path/to/suexec)"
3821 message that we had back in apache-1.3 and still have scattered
3822 throughout our docs. [Aaron Bannert]
3824 *) Prevent the Win32 port from continuing after encountering an
3825 error in the command line args to apache. [William Rowe]
3827 *) On a error in the proxy, make it write a line to the error log
3830 *) Various mod_ssl performance improvements [Doug MacEachern]
3832 Changes with Apache 2.0.29
3834 *) Add buffering in core_output_filter to ensure that long
3835 lists of small buckets don't cause small packet writes.
3836 [Brian Pane, Ryan Bloom]
3838 *) Fix the installation target to make sure that the manual is
3839 installed in the correct location.
3840 [Yoshifumi Hiramatsu <hiramatu boreas.dti.ne.jp> and
3841 Gomez Henri <hgomez slib.fr>]
3843 *) Fix the cmd command for mod_include. When we are processing
3844 a cmd command, we do not want to use the r->filename to set
3845 the command name. The command comes from the SSI tag. To do this,
3846 I added a variable to the function that builds the command line
3847 in mod_cgi. This allows the include_cmd function to specify
3848 the command line itself. [Ryan Bloom]
3850 *) Change open_logs hook to return a value, allowing you
3851 to flag a error while opening logs
3852 [Ian Holsman, Doug MacEachern]
3854 *) Change post_config hook to return a value, allowing you
3855 to flag a error post config
3856 [Ian Holsman, Jeff Trawick]
3858 *) Allow SUEXEC_BIN (the path to the suexec binary that is
3859 hard-coded into the server) to be specified to the configure
3860 script by the --with-suexec-bin parameter. [Aaron Bannert]
3862 *) Fix segv in worker MPM following accept on pipe-of-death
3865 *) Add mod_deflate to experimental.
3866 [Ian Holsman, Justin Erenkrantz]
3868 *) Bail out at configure time if an invalid MPM was specified.
3869 [jean-frederic clere <jfrederic.clere fujitsu-siemens.com>]
3871 *) Prevent segv in ap_note_basic_auth_failure() when no AuthName is
3872 configured [John Sterling <sterling covalent.net>]
3874 *) Fix apxs to use sbindir. [Henri Gomez <hgomez slib.fr>]
3876 *) Fix a problem with IPv6 vhosts. PR #8118 [Jeff Trawick]
3878 *) Optimization for the BNDM string-search function in
3879 mod_include. [Brian Pane]
3881 *) Fixed the behavior of the XBitHack directive.
3882 [Taketo Kabe <kabe sra-tohoku.co.jp>, Cliff Woolley] PR#8804
3884 *) The threaded MPM for Unix has been removed. Use the worker
3885 MPM instead. [various]
3887 *) APR-ize the resolver logic in mod_unique_id. This fixes a bug
3888 in logging the error from a failed DNS lookup. [Jeff Trawick]
3890 *) Added the missing macros AP_INIT_TAKE13 and AP_INIT_TAKE123.
3893 *) Get mod_cgid killed when a MPM exits due to a fatal error.
3896 *) Fix a file descriptor leak in mod_include. When we include a
3897 file, we use a sub-request, but we didn't destroy the sub-request
3898 immediately, instead we waited until the original request was
3899 done. This patch closes the sub-request as soon as the data is
3900 done being generated. [Brian Pane <bpane pacbell.net>]
3902 *) Allow modules that add sockets to the ap_listeners list to
3903 define the function that should be used to accept on that
3904 socket. Each MPM can define their own function to use for
3905 the accept function with the MPM_ACCEPT_FUNC macro. This
3906 also abstracts out all of the Unix accept error handling
3907 logic, which has become out of synch across Unix MPMs.
3910 *) Fix a bug which would cause the response headers to be omitted
3911 when sending a negotiated ErrorDocument because the required
3912 filters were attached to the wrong request_rec.
3913 [John Sterling <sterling covalent.net>]
3915 *) Remove commas from the end of the macros that define
3916 directives that are used by MPMs. Prior to this patch,
3917 you would use these macros without commas, which was unlike
3918 the macros for any other directives. Now, the caller provides
3919 the comma rather than the macro providing it. This makes
3920 the macros look more like the rest of the directives.
3921 [Ryan Bloom and Cliff Woolley]
3923 *) Add 'redirect-carefully' environment option to disable sending
3924 redirects under special circumstances. This is helpful for
3925 Microsoft's WebFolders when accessing a directory resource via
3926 DAV methods. [Justin Erenkrantz]
3928 *) Begin to abstract out the underlying transport layer.
3929 The first step is to remove the socket from the conn_rec,
3930 the server now lives in a context that is passed to the
3931 core's input and output filters. This forces us to be very
3932 careful when adding calls that use the socket directly,
3933 because the socket isn't available in most locations.
3936 *) Really reset the MaxClients value in worker and threaded
3937 when the configured value is not a multiple of the number
3938 of threads per child. We said we did previously but we
3939 forgot to. [Jeff Trawick]
3941 *) Add Debian layout. [Daniel Stone <daniel sfarc.net>]
3943 *) If shared modules are requested and mod_so is not available,
3944 produce a fatal config-time error. [Justin Erenkrantz]
3946 *) Improve http2env's performance by cutting the work it has to
3947 do. [Brian Pane <bpane pacbell.net>]
3949 *) use new 'apr_hash_merge' function in mod_mime (performance fix)
3950 [Brian Pane <bpane pacbell.net>]
3952 Changes with Apache 2.0.28
3954 *) Fix infinite loop in mod_cgid.c.
3955 [Dale Ghent <daleg elemental.org>, Brian Pane <bpane pacbell.net>]
3957 *) When no port is given in a "ServerName host" directive, the
3958 server_rec->port is now set to zero, not 80. That allows for
3959 run-time deduction of the correct server port (depending on
3960 SSL/plain, and depending also on the current setting of
3961 UseCanonicalName). This change makes redirections
3962 work, even with https:// connections. As in Apache-1.3, the
3963 connection's actual port number is never used, only the ServerName
3964 setting or the client's Host: setting. Documentation updated
3965 to reflect the change. [Martin Kraemer]
3967 *) Add a '%{note-name}e' argument to mod-headers, which works in
3968 the same way as mod_log_confg. [Ian Holsman]
3970 *) Fix the spelling of the AP_MPMQ_MIN_SPARE_DAEMONS and
3971 AP_MPMQ_MAX_REQUESTS_DAEMON macros in ap_mpm.h and all standard
3972 MPMs. [Cliff Woolley]
3974 *) Introduce htdbm, a user management utility for db/dbm authorization
3975 databases. [Mladen Turk <mturk mappingsoft.com>]
3977 *) Optimize usage of strlen and strcat in ap_directory_walk.
3978 [Brian Pane <bpane pacbell.net>]
3980 Changes with Apache 2.0.27
3982 *) Introduce an Apache mod_ssl initial configuration template
3983 (ssl.conf, generated from ssl-std.conf). [Ralf S. Engelschall]
3985 *) Fixed a memory leak in the getline parsing code that could
3986 be triggered by arbitrarily large header lines. Requests
3987 from the core input filter for single lines are now limited
3988 to HUGE_STRING_LEN (8192 bytes). [Aaron Bannert]
3990 *) Fix a truncation bug in how we print the port on the Via: header.
3991 The routine that prints the Via: header now takes a length for
3992 the port string. [Zvi Har'El <rl math.technion.ac.il>]
3994 *) Some syntax errors in mod_mime_magic's magic file can result
3995 in a 500 error, which previously was unlogged. Now we log the
3996 error. [Jeff Trawick]
3998 *) Add the support/checkgid helper app, which checks the run-time
3999 validity of group identifiers usable in the Group directive.
4002 *) Various --enable-so options have been fixed: --enable-so is
4003 treated as "static"; explicit --enable-so=shared issues an error;
4004 and explicit --enable-so fails with error on systems without
4005 APR_HAS_DSO. [Aaron Bannert]
4007 *) Fix a segfault in the core input filter when the client socket
4008 gets disconnected unexpectedly. [Cliff Woolley]
4010 *) Fix the reporting for child processes that die. This removes
4011 all of the non-portable W* macros from Apache.
4012 [Jeff Trawick and Ryan Bloom]
4014 *) Win32: Track and display "Parent Server Generation:" in
4015 mod_status output. The generation will be bumped at
4016 server graceful restart, when the child process exits
4017 by hitting MaxRequestsPerChild or if the child
4018 process exits abnormally. [Bill Stoddard]
4020 *) Win32: Fix problem where MaxRequestsPerChild directive was
4021 not being picked up in favor of the default. Enable
4022 the parent to start up a new child process immediately upon
4023 the old child starting shutdown.
4026 *) Fix some bungling of the remote port in rfc1413.c so that
4027 IdentityCheck retrieves the proper user id instead of failing
4028 and thus always returning "nobody."
4029 [Dick Streefland <Dick.Streefland xs4all.nl>]
4031 *) Introduced thread saftey for mod_rewrite's internal cache.
4032 [Brian Pane <bpane pacbell.net>]
4034 *) Simplified mod_env's directives to behave as most directives are
4035 expected, in that UnsetEnv will not unset a SetEnv and PassEnv
4036 directive following that UnsetEnv within the same container.
4037 Also provides a runtime startup warning if a PassEnv configured
4038 environment value is undefined. [William Rowe]
4040 *) The worker MPM is now completely ported to APR's new lock API. It
4041 uses native APR types for thread mutexes, cross-process mutexes,
4042 and condition variables. [Aaron Bannert]
4044 *) Sync up documentation to remove all references to the now deprecated
4045 Port directive. [Justin Erenkrantz]
4047 *) Moved all ldap modules from the core to httpd-ldap sub-project
4050 *) Exit when we can't listen on any of the configured ports. This
4051 is the same behavior as 1.3, and it avoids having the MPMs to
4052 deal with bogus ap_listen_rec structures. [Jeff Trawick]
4054 *) Cleanup the proxy code that creates a request to the origin
4055 server. This change adds an optional hook, which allows modules
4056 to gain control while the request is created if the proxy module
4057 is loaded. The purpose of this hook is to allow modules to add
4058 input and/or output filters to the request to the origin. While
4059 I was at it, I made the core use this hook, so that proxy request
4060 creation uses some of the code from the core. This can still be
4061 greatly improved, but this is a good start. [Ryan Bloom]
4063 Changes with Apache 2.0.26
4065 *) Port the MaxClients changes from the worker MPM to the threaded
4068 *) Fix mod_proxy so that it handles chunked transfer-encoding and works
4069 with the new input filtering system. [Justin Erenkrantz]
4071 *) Introduce the MultiviewsMatch directive, to allow the operator
4072 to be flexible in recognizing Handlers and Filters filename
4073 extensions as part of the Multiviews matching logic, strict with
4074 MultiviewsMatch NegotiatedOnly to accept only filename extentions
4075 that designate negotiated parameters, (content type, charset, etc.)
4076 or MultiviewsAll for the 1.3 behavior of matching any files, even
4077 if they have unregistered extensions. [William Rowe]
4079 *) Fixed the configure script to add a LoadModule directive to
4080 the default httpd.conf for any module that was compiled
4081 as a DSO. [Aaron Bannert <aaron clove.org>]
4083 *) rewrite mod_ssl input filtering to work with the new input filtering
4084 system. [Justin Erenkrantz]
4086 *) prefork: Don't segfault when we are able to listen on some but
4087 not all of the configured ports. [Jeff Trawick]
4089 *) Build mod_so even if no core modules are built shared.
4090 [Aaron Bannert <aaron clove.org>]
4092 *) Introduce ap_directory_walk rewrite (with further optimizations
4093 required) to adapt to the ap_process_request_internal() changes.
4094 Optimized so subrequests and redirects now reuse previous section
4095 merges, until we mismatch with the original directory_walk, and
4096 precomputed r->finfo results will cause directory_walk to skip
4097 the most expensive phases of the function. [William Rowe]
4099 *) Allow ApacheMonitor to connect to and control Apache on other
4100 WinNT/2K machines. [Mladen Turk <mturk mappingsoft.com>]
4102 *) Remove the Port directive. In it's place, the Listen directive
4103 is now a required directive, which tells Apache what port to
4104 listen on. The ServerName directive has also been extended
4105 to accept an optional port. If the port is specified to the
4106 ServerName, the server will report that port whenever it
4107 reports the port that it is listening on. This change was
4108 made to ease configuration errors that stem from having a Port
4109 directive, and a Listen directive. In that situation, the server
4110 would only listen to the port specified by the Listen command,
4111 which caused a lot of confusion to users. [Ryan Bloom]
4113 *) Added mod_mime_magic, mod_unique_id and mod_vhost_alias to the Win32
4114 build, as loadable modules. [William Rowe]
4116 *) Fix --enable-mods-shared processing. If most is specified,
4117 then all modules that can be compiled as shared modules are.
4118 [Aaron Bannert <aaron clove.org>]
4120 *) Update the mime.types file to map video/vnd.mpegurl to mxu
4121 and add commonly used audio/x-mpegurl for m3u extensions.
4122 [Heiko Recktenwald <uzs106 uni-bonn.de>, Lars Eilebrecht]
4124 *) Eliminate the depreciated r->content_language, in favor of the array
4125 r->content_languages introduced many years ago. Module authors must
4126 substantially overhaul their modules, so this needs to be upgraded
4127 if the module still relied on backwards-brokeness. [William Rowe]
4129 *) Allow configure help strings to work with autoconf 2.50+ and 2.13.
4132 *) Rewrite the input filtering mechanisms to consolidate and reorganize
4133 code. In short, core_input_filter does something now and
4134 ap_http_filter is now only concerned with HTTP. [Justin Erenkrantz]
4136 *) Update the Win32 build to re-absorb mod_proxy and family.
4139 *) Resolved the build failure on Win32 using MSVC 5.0 (without the
4140 current SDK.) [William Rowe]
4142 *) Some style changes to the code that does ProxyErrorOverride. Fixed
4143 config merge behaviour. [Graham Leggett]
4145 *) Allow support programs to be compiled against a static version
4146 of libapr. This allows the smaller support programs to be
4147 relocated. [Aaron Bannert <aaron clove.org>]
4149 *) Update the mime.types file to the registered media types as
4150 of 2001-09-25, and add mapping for xsl extension [Mark Cox]
4152 *) Fix MaxClients in the Worker MPM, so that it specifies the maximum
4153 number of clients that can connect at the same time, instead of
4154 specifying the maximum number of child processes.
4155 [Aaron Bannert <aaron clove.org>]
4157 *) Switch proc_pthread AcceptMutex configuration directive to pthread to
4158 be consistent with 1.3. [Justin Erenkrantz]
4160 *) Cache apr_explode_localtime() value for 15 seconds.
4161 [Brian Pane <bpane pacbell.net>]
4163 *) Fix mod_include to not return ETag or Last-Modified headers.
4164 [Ian Holsman <ianh cnet.com>]
4166 *) Fix worker MPM's scoreboard logic. [Aaron Bannert <aaron clove.org>]
4168 *) Eliminate the wasteful run-time conversion of method names from strings
4169 to numbers in places where the methods are known at compile time.
4170 [Brian Pane <bpane pacbell.net>]
4172 *) Turn the worker MPM's queue into a LIFO. This may
4173 improve cache-hit performance under some conditions.
4174 [Aaron Bannert <aaron clove.org>]
4176 *) Switch back to SIGUSR1 for graceful restarts on all platforms that
4177 support it. [Justin Erenkrantz]
4179 *) Cleanup the worker MPM. We no longer re-use transaction
4180 pools. This incurs less overhead than shuffling the pools
4181 around so that they can be re-used. Remove one of the
4182 queue's condition variables. We just redefined the API to
4183 state that you can't try to add more stuff than you allocated
4184 segments for. [Aaron Bannert <aaron clove.org>]
4186 *) Fix SSL VPATH builds [Cody Sherr <csherr covalent.net>]
4188 *) Fixed persistent connections when a request contains a body.
4191 *) mod_dav uses a new API to speak to the backend provider for dead
4192 property management. [Greg Stein]
4194 *) Remove the Win32 script-processing exception from mod_cgi, and
4195 roll build_command_line/build_argv_list into a unified, overrideable
4196 ap_cgi_build_command optional function. [William Rowe]
4198 *) Rewrite find_start_sequence to use a better search algorithm
4199 to find the start tag. [Justin Erenkrantz]
4201 *) Fix a seg fault in mod_include. When we are generating an
4202 internal redirect, we must set r->uri to "", not a bogus
4203 string, and not NULL. [Ryan Bloom]
4205 *) Optimized location_walk, so subrequests, redirects and second passes
4206 now reuse previous section merges on a <Location > by <Location >
4207 basis, until we mismatch with the original location_walk.
4210 *) Back out the 1.45 change to util_script.c. This change made
4211 us set the environment variable REQUEST_URI to the redirected
4212 URI, instead of the originally requested URI.
4213 [Taketo Kabe <kabe sra-tohoku.co.jp>]
4215 *) Make mod_include do lazy evaluation of potentially expensive to
4216 compute variables. [Brian Pane <bpane pacbell.net>]
4218 *) Fix logging of bytes sent for HEAD requests. %b and %B should
4219 log either - or 0, before this patch, they were both logging
4220 the file size. [Taketo Kabe <kabe sra-tohoku.co.jp>]
4222 *) Make mod_include check for BYTE_CHECK_THRESHOLD per bucket rather
4223 than per character. [Brian Pane <bpane pacbell.net>]
4225 *) Normalize the primary request, redirects and sub-requests to
4226 run the same ap_process_request_internal for consistency in
4227 robustness, behavior and security. [William Rowe]
4229 *) Fix a segfault with mod_include when r->path_info is not set
4230 (which is the case with mod_proxy). [Ian Holsman <ianh cnet.com>]
4232 *) Add -X functionality back. This indicates to all MPMs and any other
4233 part of Apache that it should run in "debug" mode. [Justin Erenkrantz]
4235 *) Some initial support for the cygwin platform [prefork only].
4236 This is not to be confused with support for the WinNT/Win32
4237 platform, which is the recommended configuration for native
4238 Win32 users. The cygwin platform support is recommended for
4239 cygwin platform users. [Stipe Tolj <tolj wapme-systems.de>]
4241 *) Changed syntax of Set{Input|Output}Filter. The list of filters
4242 must be semicolon delimited (if more than one filter is given.)
4243 The Set{Input|Output}Filter directive now overrides a parent
4244 container's directive (e.g. SetInputFilter in <Directory /web/foo>
4245 will override any SetInputFilter directive in <Directory /web>.)
4246 This new syntax is more consistent with Add{Input|Output}Filter
4247 directives defined in mod_mime. Also cures a bug in prior releases
4248 where the Set{Input|Output}Filter directive would corrupt the
4249 global configuration if the multiple directives were nested.
4252 *) Cured what's ailed mime for quite some time. If an AddSomething
4253 was given in the configuration (Language, Charset, Handler or
4254 Encoding) Apache would set the content type as given by AddType,
4255 but refused to check the mime.types file if AddType wasn't given
4256 for that specific extension. Setting the AddHandler for .html
4257 without setting the AddType text/html html would cause Apache to
4258 use the default content type. [William Rowe]
4260 *) Added some bulletproofing to memory allocation in the LDAP cache
4261 code. [Graham Leggett]
4263 Changes with Apache 2.0.25
4265 *) Move the installed /manual directory out of the /htdocs/ tree, so
4266 that it can be kept more independently from the remaining document
4267 root. The "Alias /manual ..." already allowed for easy projection
4268 into existing private document trees. [Martin Kraemer]
4270 *) Add specified user attributes to the environment when using
4271 mod_auth_ldap. This allows you to use mod_include to embed specified
4272 user attributes in a page like so:
4273 Hello <!--#echo var="AUTHENTICATE_CN"-->, how are you?
4276 *) Fix a performance problem with the worker MPM. We now create
4277 transaction pools once, and re-use them for each connection.
4278 [Aaron Bannert <aaron clove.org>]
4280 *) Modfied mod_mime to prevent mod_negotation from serving a multiview
4281 of a 'handler' or 'filter', so that any filename extension that does
4282 not contribute to the negotiated metadata can't be served without
4283 an explicit request. E.g., if the .Z extension is associated with
4284 an unzip filter, the user request somefile.Z.html, mod_negotiation
4285 won't serve it. It can serve somefile.Z.html when somefile.Z is
4286 requested, since the .Z extension is explictly requested, if the
4287 .html extension is associated with ContentType text/html.
4290 *) Introduce the AddInputFilter filter[;filter...] ext [ext...]
4291 and corresponding AddOutputFilter syntax, to insert one or more
4292 filters by mod_mime filename extension processing.
4295 *) Fix a growing connection pool in core_output_filter() for
4296 keepalive requests. [Jeff Trawick]
4298 *) Moved split_and_pass_pretag_buckets back to being a
4299 macro at Ryans's request. Removed the return from it
4300 by setting and returning a return code instead. Updated
4301 the code to check the return code from the macro and
4302 do the right thing. [Paul J. Reder]
4304 *) Fix a segfault when a numeric value was received for Host:.
4307 *) Add a function ap_remove_input_filter. This is to match
4308 up with ap_remove_output_filter. [Ryan Bloom]
4310 *) Clean up location_walk, so that this step performs a minimum
4311 amount of redundant effort (it must be run twice, but it will no
4312 longer reparse all <Location > blocks when the request uri
4313 hadn't changed.) [William Rowe]
4315 *) Eliminate proxy: (and all other 'special') processing from the
4316 ap_directory_walk() phase. Modules that want to use special
4317 walk logic should refer to the mod_proxy map_to_location example,
4318 with it's proxy_walk and proxysection implementation. This makes
4319 either directory_walk flavor much more legible, since that phase
4320 only runs against real <Directory > blocks.
4323 *) SECURITY: Fix a security problem in mod_include which would allow
4324 an SSI document to be passed to the client unparsed.
4325 [Cliff Woolley, Brian Pane]
4327 *) Introduce the map_to_storage hook, which allows modules to bypass
4328 the directory_walk and file_walk for non-file requests. TRACE
4329 shortcut moved to http_protocol.c as APR_HOOK_MIDDLE, and the
4330 directory_walk/file_walk happen as APR_HOOK_VERY_LAST in core.c.
4333 *) Add the ability for mod_include to add the INCLUDES filter
4334 if the file is configured for the server-parsed handler.
4335 This makes the configuration for .shtml files much easier
4336 to understand, and allows mod_include to honor Apache 1.3
4337 config files. Based on Doug MacEachern's patch to PHP
4338 to do the same thing. [Ryan Bloom]
4340 *) force OpenSSL to ignore process local-caching and to always
4341 get/set/delete sessions using mod_ssl's callbacks
4342 [Madhusudan Mathihalli <madhusudan_mathihalli hp.com>,
4343 Geoff Thorpe <geoff geoffthorpe.net>]
4345 *) Make the worker MPM shutdown and restart cleanly. This also
4346 cleans up some race conditions, and gets the worker using
4347 pools more cleanly. [Aaron Bannert <aaron clove.org>]
4349 *) Implement CRYPTO_set_locking_callback() in terms of apr_lock
4351 [Madhusudan Mathihalli <madhusudan_mathihalli hp.com>]
4353 *) Fix for mod_include. Ryan's patch to check error
4354 codes put a return in the wrong place. Also, the
4355 include handler return code wasn't being checked.
4356 I don't like macros with returns, so I converted
4357 SPLIT_AND_PASS_PRETAG_BUCKETS into a function.
4358 [Paul J. Reder <rederpj raleigh.ibm.com>]
4360 *) fix segv in mod_mime if no AddTypes are configured
4361 [John Sterling <sterling covalent.net>]
4363 *) Enable ssl client authentication at SSL_accept time
4364 [Madhusudan Mathihalli <madhusudan_mathihalli hp.com>]
4366 *) Fix a segfault in mod_include when the original request has no
4367 associated filename (e.g., we're filtering the error document for
4368 a bad URI). [Jeff Trawick]
4370 *) Fix a storage leak (a strdup() call) in mod_mime_magic. [Jeff Trawick]
4372 *) The prefork and OS/2 MPMs are overwriting the pid file when a second copy
4373 of httpd is started and shuts down due to socket conflict. Moving the
4374 call to ap_log_pid solves the problem.
4376 *) Changed the late-1.3 log_config substitution %c to %X, to log the
4377 status of the closed connection, as it conflicts with the far more
4378 common, historical ssl logging directive %...{var}c. [William Rowe]
4380 *) Added the common error/ tree to the build/install targets
4381 (similar to the common icons/ tree) for the multi-language error
4382 messages that Lars committed earlier. [William Rowe]
4384 *) Added a multi process, multi threaded OS/2 MPM mpmt_os2. [Brian Havard]
4386 *) Added a default commented-out mod_ldap and mod_auth_ldap
4387 configuration to httpd-std.conf and httpd-win.conf
4390 *) Added documentation for mod_ldap and mod_auth_ldap.
4393 *) Enabled negative caching on attribute comparisons in the LDAP cache.
4394 Fixed a problem where the default cache TTL was set in milliseconds
4395 not microseconds causing the cache to time out almost immediately.
4398 *) Fixed all the #if APR_HAS_SHARED_MEMORY checks within the LDAP
4399 module code to follow APR. [Graham Leggett]
4401 *) Fixed LDAP cleanup on graceful restarts. LDAP connections are now
4402 cleaned up when the connection pool pool is cleaned up.
4405 *) Fix a minor issue with Jeff Trawick's mod_include
4406 patch. Without this patch, the code will just allocate
4407 more bytes in get_combined_directive than are needed.
4410 *) Added the LDAP authentication module mod_auth_ldap.
4411 [Dave Carrigan <dave rudedog.org>, Graham Leggett]
4413 *) Added the LDAP cache and connection pooling module mod_ldap.
4414 [Dave Carrigan <dave rudedog.org>, Graham Leggett]
4416 *) Fix --enable-modules=all breakage with mod_auth_db and mod_auth_digest
4417 by allowing a module to disable itself if its prerequisites are not
4418 met. [Justin Erenkrantz]
4420 Changes with Apache 2.0.24
4422 *) Fix a couple of issues in mod_include when the tag appeared at
4423 offsets near 8192 in the file being parsed. [Jeff Trawick]
4425 *) Fix an assertion failure in mod_ssl when the keepalive timeout is
4426 reached. [Jeff Trawick]
4428 *) Numerous improvements to the Win32 build system. Introduced command line
4429 builds without requiring .mak files for MSVC 6.0 and later versions.
4430 Improved .dsp file compatibility for both Visual Studio 5.0 and 6.0 users.
4433 *) Assorted corrections and improvements to the winnt_mpm startup code. Better
4434 reporting of uninstalled services and other error conditions, and changed the
4435 default service name to Apache2. [William Rowe]
4437 *) Numerous improvements to the Win32 ApacheMonitor utility, including winnt_mpm
4438 compatibility with existing Apache 1.3 Win32 Apache management utilites.
4439 [Mladen Turk <mturk mappingsoft.com>, William Rowe]
4441 *) Fixed the segfaults in mod_mime introduced by hash tables in 2.0.20.
4442 [William Rowe, Greg Ames]
4444 *) Rounded out the mod_mime Add/Remove pairs by adding RemoveLanguage
4445 and RemoveCharset directives. [William Rowe]
4447 *) The Unix MPMs other than perchild now allow child server
4448 processes to use the accept mutex when starting as root and
4449 using SysV sems for the accept mutex. Previously, this
4450 combination would lead to fatal errors in the child server
4451 processes. perchild can't use SysV sems because of security
4452 issues. [Jeff Trawick, Greg Ames]
4454 *) Added Win32 revision stamp resources to all http binaries
4455 (including modules/ and support/ tools.) PR7322 [William Rowe]
4457 *) Fix ap_rvprintf to support more than 4K of data at one time.
4458 [Cody Sherr <csherr covalent.net>]
4460 *) We have always used the obsolete/deprecated Netscape syntax
4461 for our tracking cookies; now the CookieStyle directive
4462 allows the Webmaster to choose the Netscape, RFC2109, or
4463 RFC2965 format. The new CookieDomain directive allows the
4464 setting of the cookie's Domain= attribute, too. PR #s 5006,
4465 5023, 5920, 6140 [Ken Coar]
4467 *) Tweak server/Makefile so that the rules for generating exports.c
4468 are compatible with make utilities which don't expand wildcards
4469 in a dependency list (e.g., OS/390 make, certain levels of GNU
4470 make). [Jeff Trawick]
4472 *) Install the SSL headers. [John Sterling <sterling covalent.net>]
4474 *) Begin to sanitize the MPM configuration directives. Now, all
4475 MPMs use the same functions for all common MPM directives. This
4476 should make it easier to catch all bugs in these directives once.
4477 [Cody Sherr <csherr covalent.net>]
4479 *) Close a major resource leak. Every time we had issued a
4480 graceful restart, we leaked a socket descriptor.
4483 *) Fix a problem with the new method code. We need to cast
4484 the 1 to an apr_int64_t or it will be treated as a 32-bit
4485 integer, and it will wrap after being shifted 32 times.
4486 [Cody Sherr <csherr covalent.net> and Ryan Morgan <rmorgan covalent.net>]
4488 *) Fix a bug in mod_expires. Previous to this patch, if you
4489 told mod_expires to add 604800 seconds to the last-modified
4490 time, it actually added 604800 usec's to the last-modified time,
4491 so that when looking at the response it looked like nothing
4492 had been done. The root of the problem was that we always compute
4493 time in usec's, but we ask users to input sec's. This means we
4494 need to convert to usec's before using those values.
4497 *) The worker MPM now handles shutdown and restart requests. It
4498 definitely isn't perfect, but we do stop the servers correctly.
4499 The biggest problem right now is that SIGHUP causes the server to
4500 just die. [Ryan Bloom]
4502 Changes with Apache 2.0.23
4504 *) Use the prefork MPM by default on Unix. [various]
4506 *) Added a systray icon monitor application for Win32.
4507 [Mladen Turk <mturk mappingsoft.com>]
4509 *) mod_rewrite: Fix the line ending on some non-Unix systems for
4510 messages written to the rewrite log.
4511 [Richard Labennett <rlabenn us.ibm.com>]
4513 *) All mod_autoindex query parsing is now quietly quashed with the
4514 IndexOption IgnoreClient. The IndexOption SuppressColumnSorting
4515 still drops the column sort <a href>'s for the column headers, but
4516 IgnoreClient is required to ignore these Query options entirely.
4519 *) Introduced new mod_autoindex query argument parsing for F=[0|1|2]
4520 to allow the client to select plain, FancyIndexing or HTMLTable
4521 formatting, V=[0|1] to inhibit or enable version sorting, and
4522 P=pattern to return only specific files. The old Query Arguments
4523 were reorganized as C=f for sorting column 'f' (same N, D, S, or M
4524 as before), and O=A|D for ordering ascending or descending.
4527 *) Fixed an error in mod_include's directive parsing routines which
4528 caused #if, #elif, and #else expressions containing backslashes
4529 to be improperly evaluated. [Cliff Woolley]
4531 *) Introduced new mod_autoindex IndexOptions flags: SuppressIcon to
4532 drop the icon column, SuppressRules to drop the <hr> elements,
4533 and HTMLTable to create rudimentary HTML table listings (implies
4534 FancyIndexing). [William Rowe]
4536 *) Re-introduced the mod_autoindex IndexOptions flag TrackModified
4537 from Apache 1.3.15. This is needed for two reasons, first, given
4538 multiple machines within a server farm, ETags and Last-Modified
4539 stamps won't correspond from machine to machine, and second, many
4540 Unixes don't capture changes to the date or time stamp of existing
4541 files, since these don't modify the dirent itself. [William Rowe]
4543 *) Re-introduced the mod_autoindex IndexOptions flag FoldersFirst
4544 and DirectoryWidth options from Apache 1.3.10.
4545 [William Rowe, Ken Coar]
4547 *) Eliminated FancyIndexing directive, deprecated early in Apache
4548 1.3 by the IndexOptions FancyIndexing syntax. [William Rowe]
4550 *) mod_autoindex now excludes any file names that would result in
4551 an error, other than a success or redirect. Also optimized
4552 the parent directory, always included except in the URI '/'.
4555 *) Refactored mod_negotiation and mod_mime to help mod_dir accept
4556 negotiated index pages, and prevent the server from defaulting
4557 to an autoindex of the directory. mod_negotiation will now die
4558 with a 500 Internal Error if it could match some filenames
4559 (e.g. for mod_dir) but none can be served. mod_negotation now
4560 refuses to serve any file with an extention that mod_mime doesn't
4561 recognize, and wasn't part of the request. [William Rowe]
4563 *) Eliminate mod_cgi's handling of .exe files without the .exe file
4564 extension. This is already handled by multiviews, if the admin
4565 wishes to AddHandler .exe or define a content type handler and
4566 associate .exe files with that content type. Multiviews must be
4567 enabled to allow these to be served. [William Rowe]
4569 *) Speed up the server's response to a spike in incoming workload
4570 or restarts by assigning empty scoreboard slots to new processes
4571 when they are available. [Greg Ames]
4573 *) Add a handler to mod_includes.c. This handler is designed to
4574 implement the XbitHack directive. This can't be done with a
4575 fixup, because we need to check the content-type, which is
4576 only available in the handler phase. [Ryan Bloom]
4578 *) Make the includes filter check return codes from filters lower in
4579 the filter chain. If a lower level filter returns an error, then
4580 the request needs to stop immediately. This allows mod_include to
4581 stop parsing data once a lower filter recognizes an error.
4584 *) Add the ability to extend the methods that Apache understands
4585 and have those methods <limit>able in the httpd.conf. It uses
4586 the same bit mask/shifted offset as the original HTTP methods
4587 such as M_GET or M_POST, but expands the total bits from an int to
4588 an ap_int64_t to handle more bits for new request methods than
4589 an int provides. [Cody Sherr <csherr covalent.net>]
4591 *) Fix broken mod_mime behavior in merging its arguments. Possible
4592 cause of unexplicable crashes introduced in 2.0.20. [William Rowe]
4594 *) Solve many mod_ssl porting issues (too many to detail) with
4595 help from the whole team, but most notably [Ralf S. Engelschall,
4596 Madhusudan Mathihalli <madhusudan_mathihalli hp.com>,
4597 Doug MacEachern, William Rowe, Cliff Woolley]
4599 *) More stall fixes for the threaded & worker mpm's.
4600 Make mod_status output more accurate. Don't
4601 count workers in processes which aren't actively
4602 serving requests. [Greg Ames]
4604 *) Win32: Get SSI exec cgi tag working. [Bill Stoddard]
4606 *) Add a single listener/multiple worker MPM. This MPM is
4607 definately not fully correct, but it allows us to solve many
4608 of the problems that exist in the threaded MPM. This is a
4609 modified version of the threaded MPM. [Ryan Bloom]
4611 *) Improve content generation throughout Apache, providing closer
4612 compliance with HTML 3.2, HTML 4.01 Transitional and XHTML 1.0
4613 Transitional specifications. [William Rowe]
4615 Changes with Apache 2.0.22
4617 *) Fix a problem where the threaded MPM stalls after restarts or
4618 segfaults. Also prevent multiple active processes from using
4619 the same scoreboard slot. [Greg Ames]
4621 *) Apache/Win32 now fills in the service description with Apache's
4622 server version string, including loaded and advertised modules.
4625 *) Improved support for the Win32 build, to recover gracefully from
4626 missing apr or apr-util directories or the awk interpreter,
4627 create the proper cgi-bin examples, including a test-cgi.bat, and
4628 fix the perl shebang line for printenv.pl, when installing from
4629 the build environment. [William Rowe]
4631 *) Fix a segfault in threaded.c caused by passing uninitialized
4632 apr_thread_t * to apr_thread_join(). [Jeff Trawick]
4634 *) Use new APR number conversion functions to reduce CPU consumption
4635 when setting the content length, and in mod_log_config.
4638 *) Fix problem reported by Taketo Kabe <kabe sra-tohoku.co.jp>
4639 where HEAD response headers were being repeated twice for
4640 files greater than 32K bytes (4*AP_MIN_BYTES_TO_WRITE). This
4641 problem in the http_header filter was exposed by the recent rewrite
4642 of the content_length filter. [Taketo Kabe, Bill Stoddard]
4644 *) Fix seg faults in mod_status with ExtendedStatus enabled, after
4645 restarts. A garbage pointer to a vhost's server_rec from the
4646 previous generation was being left around under certain
4647 conditions. [Greg Ames]
4649 *) Fix a cosmetic problem with mod_include. Non-existant SSI vars
4650 used to appear as '(none', without the closing paren.
4651 [Günter Knauf <eflash gmx.net>]
4653 *) Improve the exports generating awk script. In the past, we had
4654 work around problems in the awk script by avoiding some #if and
4655 #ifdefs. This has bitten us many times in generating the exports.c
4656 file. This improvement allows corrects the header file parsing.
4657 [Sander Striker <striker apache.org>]
4659 Changes with Apache 2.0.21
4661 *) Resolve the Win32 htpasswd bug, where a file that existed would be
4662 overwritten, regardless of the -c flag.
4663 [William Rowe, Mladen Turk <mladen.turk mail.inet.hr>]
4665 *) Introduce connection sub-pools into ab. Truncating the lifetime
4666 of these allocations means that ab no longer perpetually grows
4667 its working set, running out of memory on large request attempts.
4670 *) Make scoreboard creation a hook. This allows management
4671 modules to have access to the scoreboard at the time that it is
4672 created, and at every restart request.
4673 [Cody Sherr <csherr covalent.net>]
4675 *) Changed AP_MPMQ_MAX_DAEMONS to refer to MaxClients and
4676 added an AP_MPMQ_MAX_DAEMON_USED to refer to the highest
4677 daemon index actually used in the scoreboard. I also
4678 updated the pertinent calls. [Paul J. Reder]
4680 *) Win32: Prevent listening sockets from being inherited by
4681 the Apache child process, CGI scripts, rotatelog process
4682 etc. If the Apache child process segfaults, any processes
4683 that the child started are not reaped. Prior to this fix,
4684 these processes inherited the listening sockets which sometimes
4685 prevented the restarted Apache child process from accepting
4686 connections (ie, the server would hang).
4689 *) Provide vhost and request strings when ExtendedStatus is on.
4692 *) Fix some issues with the pod and prefork: check the pod *after*
4693 processing a connection so that a server processing a time-
4694 consuming request bails out as soon as practical; when the
4695 parent process wakes up a server process via connect(), use an
4696 APR timeout on the connect() so that we don't hang for a long
4697 time if there aren't server processes around to do accept().
4698 [Jeff Trawick, Greg Ames]
4700 *) Performance improvement to mod_mime.c. find_ct() in mod_mime,
4701 spends a lot of time in apr_table_get calls. Using the default
4702 httpd.conf, the tables for languages and charsets are somewhat
4703 large, so the time spent scanning them on each request is
4704 significant. Replacing the tables with hash tables provides
4705 a nice speedup. [Brian Pane <bpane pacbell.net>]
4707 *) Add two functions to allow modules to access random parts of the
4708 scoreboard. This allows modules compiled for one MPM to access the
4709 scoreboard, even if it the server was compiled for another MPM.
4710 [Harrie Hazewinkel <harrie covalent.net>]
4712 Changes with Apache 2.0.20
4714 *) Fix problem in content-length filter where the filter would
4715 buffer all the output from a CGI before sending any bytes
4716 down the filter stack to the network. This problem would cause
4717 significant memory consumption if the CGIs generated
4718 lots of bytes. [Bill Stoddard]
4720 *) Get non-blocking CGI pipe reads working with the bucket brigades.
4723 *) Fix seg fault on Windows when serving files cached with mod_file_cache.
4726 *) Fix a bug in the threaded MPM that would cause it to kill off all
4727 workers immediately after starting if the number of workers started
4728 was above a certain threshold. [Ryan Bloom, Bill Stoddard]
4730 Changes with Apache 2.0.19
4732 *) Fix problem with threaded MPM. The problem was that if each child
4733 process was busy serving a single long-lived request and the server
4734 was sent a graceful restart signal, the server would stop serving
4735 requests. This would happen because each child process would wait to
4736 die until the last thread was done, and the parent wouldn't spawn any
4737 new children until a process died. Now, the parent looks at the fact
4738 that the children are dying gracefully, and starts new children.
4739 Those new children only start enough threads to compliment the number
4740 of threads in the other child process that shares the same spot in
4741 the scoreboard. In this way, we make sure to never go over
4742 MaxClients. [Ryan Bloom]
4744 *) modified mod_negotiation and mod_autoindex to speed up by almost a
4745 factor of two on apr_dir_read()-enhanced platforms, such as Win32
4746 and OS2, by calling ap_sub_request_lookup_dirent() with the results
4747 already provided by apr_dir_read(). [William Rowe]
4749 *) mod_file_cache is now more robust to filtering and serves requests
4750 slightly more efficiently. [Cliff Woolley]
4752 *) Fix problem handling FLUSH bucket in the chunked encoding filter.
4753 Module was calling ap_rwrite() followed by ap_rflush() but the
4754 served content was not being displayed in the browser. Inspection
4755 of the output stream revealed that the first data chunk was
4756 missing the trailing CRLF required by the RFC. [Bill Stoddard]
4758 *) apxs no longer generates ap_send_http_header() in the example handler
4760 *) Fix an ab problem which could cause a divide-by-zero exception
4761 with certain invocations (e.g., ab -k -c 6 -n 100 localhost/).
4762 [Ian Holsman <ianh cnet.com>]
4764 *) Solve case-insensitive platforms' confusion about negotiated
4765 filenames, allowing files of differnt case to match in choosing
4766 the document to serve. [William Rowe]
4768 *) Fix brokenness when ThreadsPerChild is higher than the built-in
4769 limit. We left ap_threads_per_child at the higher value which
4770 led to segfaults when doing certain scoreboard operations.
4773 *) Fix seg faults and/or missing output from mod_include. The
4774 default_handler was using the subrequest pool for files and
4775 MMAPs, even though the associated APR structures typically
4776 live longer than the subrequest. [Greg Ames]
4778 *) Extend mod_setenvif to support specifying regular expressions
4779 on the SetEnvIf (and SetEnvIfNoCase) directive attribute field.
4780 Example: SetEnvIf ^TS* [a-z].* HAVE_TS
4781 will cause HAVE_TS to be set if any of the request headers begins
4782 with "TS" and has a value that begins with any character in the
4783 set [a-z]. [Bill Stoddard]
4785 *) httpd children now re-bind themselves to a random CPU on
4786 multiprocessor systems on AIX via bindprocessor() in 2.0.
4787 [Victor J. Orlikowski]
4789 *) Fix htdigest. It would go into a loop in getline when adding
4790 a second user. [Bill Stoddard]
4792 *) Win32 platforms now fully support mod_userdir options. [Will Rowe]
4794 *) Automatically generate httpd.exp for AIX.
4795 DSOs now work again on AIX in 2.0
4796 [Victor J. Orlikowski]
4798 *) Add a new request hook, error_log. This phase allows modules
4799 to act on the error log string _after_ it has been written
4800 to the error log. The goal for this hook is to allow monitoring
4801 modules to send the error string to the monitoring agent.
4804 *) Modify mod_echo to make it use filters for input and output.
4805 [Ryan Morgan <rmorgan covalent.net>]
4807 *) Extend mod_headers to support conditional driven Header
4808 add, append and set. Use SetEnvIf to set an envar and conditionally
4809 add/append/set headers based on this envar thusly:
4811 SetEnvIf TSMyHeader value HAVE_TSMyHeader
4812 Header add MyHeader "%t %D" env=HAVE_TSMyHeader
4814 If the request contains header "TSMyHeader: value" then header
4815 MyHeader: "t=xxxxxxxxxx D=yyyy" will be sent on the response.
4818 *) Extend mod_headers to support using format specifiers on Header
4819 add, append and set header values. Two format specifiers are supported:
4821 %t - reports, in UTC microseconds since the epoch, when the
4822 request was received.
4824 %D - reports the time, in microseconds, between when the request was
4825 received and the response sent.
4828 Header add MyHeader "This request served in %D microseconds. %t"
4830 results in a header being added to the response that looks like this:
4832 MyHeader: This request served in D=5438 microseconds. t=991424704447256
4836 *) Fix reset_filter(). We need to be careful how we remove filters.
4837 If we set r->output_filters to NULL, we also have to reset the
4838 connection's filters. [John Sterling]
4840 *) Optimise reset_filter() in http_protocol.c. [Greg Stein]
4842 *) Add a check to ap_die() to make sure the filter stack is sane and
4843 contains the correct basic filters when an error occurs. This fixes
4844 a problem where headers are not being sent on error. [John Sterling]
4846 *) New Header directive 'echo' option. "Header echo regex" will
4847 cause any headers received on the request that match regex to be
4848 echoed to (included in) the response headers.
4851 *) include/ap_compat.h tested and set APR_COMPAT_H instead of AP_COMPAT_H.
4852 This prevented the inclusion of apr_compat.h. PR #7773
4853 [Oleg Broytmann <phd phd.pp.ru>]
4855 *) Moved util_uri to the apr-util library. This required a bunch of
4856 apr_name changes for the uri utility functions. [Justin Erenkrantz]
4858 *) Move the addition of default AP_HTTP_HTTP_HEADER filters to the
4859 insert_filter phase so that other filters are not bypassed by default.
4862 *) Reimplement mod_headers as an output filter. mod_headers can now
4863 add custom headers to inbound requests using the RequestHeader directive
4864 and to responses using the same old Header directive. [Graham Leggett]
4866 Changes with Apache 2.0.18
4868 *) Fix command-line processing so that if a bad argument is specified
4869 Apache will exit. [Jeff Trawick]
4871 *) Change the make targets and rules to be consistent in all of the
4872 Apache-owned source trees. [Roy Fielding]
4874 *) Fix processing of the TRACE method. Previously we passed bogus
4875 parms to form_header_field() and it overlaid some vhost structures,
4876 resulting in a segfault in check_hostalias().
4877 [Greg Ames, Jeff Trawick]
4879 *) Win32: Add support for reliable piped logs. If the logging process
4880 goes down, Apache will automatically restart it. This function has
4881 been part of Apache on Unix/Linux/BSD since the early v1.3 releases.
4884 *) Do not start piped log processes during the config file
4885 preflight. This change also circumvents a problem on
4886 Windows where the rotatelog processes created during preflight
4887 was not getting cleaned up properly.
4890 *) add "Request Phase Participation" info to mod_info
4893 *) Make first phase changes to the scoreboard data structures in
4894 preparation for the rewriting of the scoreboard per my posted
4895 design notes. [Paul J. Reder]
4897 *) Fix httpd's definition of LTFLAGS to be consistent with that of apr
4898 and apr-util, allow it to be overridden by the configure command-line
4899 (default="--silent") and introduce LT_LDFLAGS to replace what we were
4900 formerly abusing as LTFLAGS. [Roy Fielding]
4902 *) Clean up the reporting of incorrect closing container tags.
4903 [Barrie Slaymaker <barries slaysys.com>]
4905 *) Simplify the configure process by moving all libtool stuff to APR
4906 and moving hints.m4 inline. [Roy Fielding]
4908 *) Add the AP_DECLARE()/AP_CORE_DECLARE macros on the return types
4909 of functions used by mod_proxy for export in the DLL
4910 [Ian Holsman <IanH cnet.com>]
4912 *) Prevent a hang when a cgi handled by mod_cgid tries to read a
4913 request body from its stdin but no reqest body is being written to
4914 the cgi. [Jeff Trawick]
4916 *) mod_log_config: %c connection status incorrectly logged
4917 as "-" (non-keepalive) when MaxKeepAliveRequests is set to 0.
4920 *) Get mod_cern_meta working under Windows
4923 *) Create Files, and thus MMAPs, out of the request pool, not the
4924 connection pool. This solves a small resource leak that had us
4925 not closing files until a connection was closed. In order to do
4926 this, at the end of the core_output_filter, we loop through the
4927 brigade and convert any data we have into a single HEAP bucket
4928 that we know will survive clearing the request_rec.
4929 [Ryan Bloom, Justin Erenkrantz <jerenkrantz ebuilt.com>,
4932 *) Completely revamp configure so that it preserves the standard make
4933 variables CPPFLAGS, CFLAGS, CXXFLAGS, LDFLAGS and LIBS by moving
4934 the configure additions to EXTRA_* variables. Also, allow the user
4935 to specify NOTEST_* values for all of the above, which eliminates the
4936 need for THREAD_CPPFLAGS, THREAD_CFLAGS, and OPTIM. Fix the setting
4937 of INCLUDES and EXTRA_INCLUDES. Check flags as they are added to
4938 avoid pointless duplications. Fix the order in which flags are given
4939 on the compile and link lines. Remove obsolete macros APR_DOEXTRA,
4940 AC_ADD_LIBRARY, AC_CHECK_DEFINE, APACHE_PASSTHRU, and APACHE_ONCE.
4941 Added APR_SAVE_THE_ENVIRONMENT and APR_RESTORE_THE_ENVIRONMENT macros.
4942 Renamed AC_TYPE_RLIM_T macro to APACHE_TYPE_RLIM_T. [Roy Fielding]
4944 *) Get mod_tls to compile/work better on Windows. PR #7612
4945 [Bernhard Schrenk <b.schrenk improx.com>]
4947 *) Fix shutdown/restart hangs in the threaded MPM.
4948 [Jeff Trawick, Greg Ames, Ryan Bloom]
4950 *) Removed the keptalive boolean from conn_rec because it is now only
4951 used by a single routine and can be replaced by a local variable.
4952 [Greg Stein, Ryan Bloom, Roy Fielding]
4954 *) Patch prefork to put enough of the signal processing back in so that
4955 signals are all handled properly now. The previous patch fixed the
4956 deadlock race condition, but broke the user directed signal handling.
4957 This fixes it to work the way it did before my previous prefork patch
4958 (primarily, SIGTERM is now working).
4960 *) Change how input filters decide how much data is returned to the
4961 higher filter. We used to use a field in the conn_rec, with this
4962 change, we use an argument to ap_get_brigade to determine how much
4963 data is retrieved. [Ryan Bloom]
4965 *) Fix seg fault at start-up introduced by Ryan's change to enable
4966 modules to specify their own logging tags. mod_log_config
4967 registers an optional function, ap_register_log_handler().
4968 ap_register_log_handler() was being called by http_core before
4969 the directive hash table was created. This patch creates the
4970 directive hash table before ap_register_log_handler() is
4971 registered as an optional function.
4972 [jean-frederic clere <jfrederic.clere fujitsu-siemens.com>]
4974 *) Add ap_set_int_slot() function
4975 [John K. Sterling <sterling covalent.net>]
4977 *) Under certain circumstances, Apache did not supply the
4978 right response headers when requiring authentication.
4979 [Gertjan van Wingerde <Gertjan.van.Wingerde cmg.nl>] PR#7114
4980 (This is a port of the change that went into Apache 1.3.19.)
4982 *) Allow modules to specify their own logging tags. This basically
4983 allows a module to tell mod_log_config that when %x is encountered
4984 a specific function should be called. Currently, x can be any single
4985 character. It may be more useful to make this a string at some point.
4988 Changes with Apache 2.0.17
4990 *) If a higher-level filter handles the byterange aspects of a
4991 request, then the byterange filter should not try to redo the
4992 work. The most common case of this happening, is a byterange
4993 request going through the proxy, and the origin server handles
4994 the byterange request. The proxy should ignore it.
4995 [Graham Leggett <minfrin sharp.fm>]
4997 *) Changed the threaded mpm to have child_main join to each of the
4998 worker threads to make sure the kids are all gone before child_main
4999 exits after a signal (cleanup from perform_idle_server_maintenance).
5000 This is an extension of Ryans recent commit to make the child_main
5003 *) Add more options to the ap_mpm_query function. This also allows MPMs to
5004 report if their threads are dynamic or static. Finally, this also
5005 implements a new API, ap_show_mpm, which returns the MPM that was
5006 required into the core. [Harrie Hazewinkel <harrie covalent.net>]
5008 *) Do not install the binaries from the support directory twice.
5009 [jun-ichiro hagino <itojun iijlab.net>]
5011 *) The ap_f* functions should flush data to the filter that is passed
5012 in, not the filter after the one passed in.
5013 [Ryan Morgan <rmorgan covalent.net>]
5015 *) Make ab work again by changing its native types to apr types and formats.
5016 [Justin Erenkrantz <jerenkrantz ebuilt.com>]
5018 *) Move the byterange filter and all of the supporting functions back
5019 to the HTTP module. The byterange filter turned out to be very
5020 HTTP specific, and it belongs in the HTTP module. [Greg Stein]
5022 *) Make clean, distclean, and extraclean consistently according to the
5023 Gnu makefile guidelines. [Justin Erenkrantz <jerenkrantz ebuilt.com>]
5025 *) Fix errors in the renaming of the apr_threadattr_detach_xxx functions.
5026 This may have been causing problems stopping processes in the threaded
5029 *) Fix content-length in mod_negotiation to a long int representation.
5032 *) Remove BindAddress from the default config file.
5033 [<giles nemeton.com.au>]
5035 *) Allow module authors to add a module to their Apache build using
5036 --with-module, without re-running buildconf. The syntax is:
5037 --with-module=module_type:/path/to/module.c
5038 The configure script will copy the module.c file to
5039 modules/module_type, and it will be added to the relevant Makefiles.
5040 currently, this only works for static modules. [Ryan Bloom]
5042 *) Changes required to make prefork clean up idle children properly.
5043 There was a window during which a starting worker deadlocks when
5044 an idle cleanup arrives before it completes init. Apache then keeps
5045 trying to cleanup the same deadlocked worker forever (until higher
5046 pids come along, but it still will never reduce below the deadlocked
5047 pid). Thus the number of children would not reduce to the correct
5048 idle level. [Paul J. Reder]
5050 Changes with Apache 2.0.16
5052 *) Change the default installation directory to /usr/local/apache2,
5053 as now defined by the "Apache" layout in config.layout. [Marc Slemko]
5055 *) OS/2: Added support for building loadable modules as OS/2 DLLs.
5058 *) Get MaxRequestsPerChild working with the Windows MPM.
5061 *) Make generic hooks to work, with mod_generic_hook_import/export
5062 experimental modules. [Ben Laurie, Will Rowe]
5064 *) Fix segfaults for configuration file syntax errors such as
5065 "<Directory>" followed by "</Directory" and
5066 "<Directory>" followed by "</Directoryz>". [Jeff Trawick]
5068 *) Cleanup the --enable-layout option of configure. This makes
5069 us use a consistent location for the config.layout file, and it
5070 makes configure more portable.
5071 [jun-ichiro hagino <itojun iijlab.net>]
5073 *) Changes to 'ab'; fixed int overrun's, added statistics, output in
5074 csv/gnuplot format, rudimentary ssl support and various other tweaks
5075 to make results more true to what is measured. The upshot of this it
5076 turns out that 'ab' has often underreported the true performance of
5077 apache. Often by a order of magnitude :-) See talk/paper of Sander
5078 Temme at April ApacheCon 2001 for details.
5079 [Dirk-Willem van Gulik]
5081 *) Clean up mod_cgid's temporary request pool. Besides fixing a
5082 storage leak this ensures that some unnecessary pipes are closed.
5085 *) Performance: Add quick_handler hook. This hook is called at the
5086 very beginning of the request processing before location_walk,
5087 translate_name, etc. This hook is useful for URI keyed content
5088 caches like Mike Abbott's Quick Shortcut Cache.
5091 *) top_module global variable renamed to ap_top_module [Perl]
5093 *) Move ap_set_last_modified to the core. This is a potentially
5094 controversial change, because this is kind of HTTP specific. However
5095 many protocols should be able to take advantage of this kind of
5096 information. I expect that headers will need one more layer of
5097 indirection for multi-protocol work, but this is a small step in
5098 the right direction. [Ryan Bloom]
5100 *) Enable mod_status by default. This matches what Apache 1.3 does.
5103 *) Add a ScriptSock directive to the default config file. This is
5104 only enabled when mod_cgid is used.
5105 [Taketo Kabe <kabe sra-tohoku.co.jp>]
5107 Changes with Apache 2.0.15
5109 *) Untangled the buildconf script and eliminated the need for build's
5110 aclocal.m4, generated_lists, build.mk, build2.mk, and a host of other
5111 libtool muck that is now under srclib/apr/build. [Roy Fielding]
5113 *) Win32: Don't accept more connections than we have worker threads
5117 *) Fix bug in the Unix threaded.c MPM that allowed child processes
5118 to fork() new child processes.
5121 *) SECURITY: Fix a major security problem with double-reverse lookup
5122 checking. Previously, a client connecting over IPv4 would not be
5123 matched properly when the server had an IPv6 listening socket.
5124 PR #7407 [Taketo Kabe <kiabe sra-tohoku.co.jp>]
5126 *) Change the way the beos MPM handles polling to allow it to stop and
5127 restart. Problem was the sockets being polled were being reset by
5128 the select call, so once it had accepted a connection it was no
5129 longer listening on the UDP socket we use for shutdown instructions.
5130 APR needs to be altered, patch on it's way. [David Reid]
5132 *) Empty out the brigade shared by ap_getline()/ap_get_client_block()
5133 on error exit from ap_getline(). Some other code got upset because
5134 the wrong data was in the brigade. [Greg Ames, Jeff Trawick]
5136 *) Handle ap_discard_request_body() being called more than once.
5137 [Greg Ames, Jeff Trawick]
5139 *) Get rid of an inadvertent close of file descriptor 2 in
5140 mod_mime_magic. [Greg Ames, Jeff Trawick]
5142 *) Add a hook, create_request. This hook allows modules to modify
5143 a request while it is being created. This hook is called for all
5144 request_rec's, main request, sub request, and internal redirect.
5145 When this hook is called, the r->main, r->prev, r->next
5146 pointers have been set, so modules can determine what kind of
5147 request this is. [Ryan Bloom]
5149 *) Cleanup the build process a bit more. The Apache configure
5150 script no longer creates its own helper scripts, it just
5152 [jean-frederic clere <jfrederic.clere fujitsu-siemens.com>]
5154 *) Stop the forced downgrade of the connection to HTTP/1.0 for
5155 proxy requests. [Graham Leggett]
5157 *) Avoid using sscanf to determine the HTTP protocol number in
5158 the common case because sscanf is a performance hog. From
5159 Mike Abbot's Accelerating Apache patch number 6.
5160 [Mike Abbot <mja trudge.engr.sgi.com>, Bill Stoddard]
5162 *) SECURITY: Fix a security exposure in mod_access. Previously when
5163 IPv6 listening sockets were used, allow/deny-from-IPv4-address rules
5164 were not evaluated properly (PR #7407). Also, add the ability to
5165 specify IPv6 address strings with optional prefix length on Allow
5166 and Deny. [Jeff Trawick]
5168 *) Enhance rotatelogs so that a UTC offset can be specified, and
5169 the logfile name can be formatted using strftime(3). (Brought
5170 forward from 1.3.) [Ken Coar]
5172 *) Reimplement the Windows MPM (mpm_winnt.c) to eliminate calling
5173 DuplicateHandle on an IOCompletionPort (a practice which
5174 MS "discourages"). The new model does not rely on associating
5175 the completion port with the listening sockets, thus the
5176 completion port can be completely managed within the child
5177 process. A dedicated thread accepts connections off the network,
5178 then calls PostQueuedCompletionStatus() to wake up worker
5179 threads blocked on the completion port.
5182 *) Bring forward the --suexec-umask option which allows the
5183 builder to preset the umask for suexec processes. [Ken Coar]
5185 *) Add a -V flag to suexec, which causes it to display the
5186 compile-time settings with which it was built. (Only
5187 usable by root or the AP_HTTPD_USER username.) [Ken Coar]
5189 *) Mod_include should always unset the content-length if the file is
5190 going to be passed through send_parsed_content. There is no to
5191 determine if the content will change before actually scanning the
5192 entire content. It is far safer to just remove the C-L as long
5193 as we are scanning it. [Ryan Bloom]
5195 *) Make sure Apache sends WWW-Authenticate during a reverse proxy
5196 request and not Proxy-Authenticate.
5197 [Graham Leggett <minfrin sharp.fm>]
5199 Changes with Apache 2.0.14
5201 *) Fix content-length computation. We ONLY compute a content-length if
5202 We are not in a 1.1 request and we cannot chunk, and this is a keepalive
5203 or we already have all the data. [Ryan Bloom]
5205 *) Report unbounded containers in the config file. Previously, a typo
5206 in the </container> directive could result in the rest of the config
5207 file being silently ignored, with undesired defaults used.
5210 *) Make the old_write filter use the ap_f* functions for the buffering.
5213 *) Move more code from the http module into the core server. This
5214 is core code, basically the default handler, the default input
5215 and output filters, and all of the core configuration directives.
5216 All of this code is required in order for the server to work, with or
5217 without HTTP. The server is closer to working without the HTTP
5218 module, although there is still more to do. [Ryan Bloom]
5220 *) Fix a number of SGI compile warnings throughout the server. Fix some
5221 bad parameters to apr_bucket_read(). Fix a bad statement in
5222 ap_method_in_list(). For the mod_rewrite cache use apr_time_t
5223 consistently; we were mixing apr_time_t and time_t in invalid ways
5224 before. In load_file(), call apr_dso_error() instead of
5225 apr_strerror() so that we get a more specific string on some platforms.
5226 PR #6980 [Jeff Trawick]
5228 *) Allow modules to query the MPM about it's execution profile. This
5229 query API can and should be extended in the future, but for now,
5230 max_daemons, and threading or forking is a very good start.
5231 [Jon Travis <jtravis covalent.net>]
5233 *) Modify mod_include to send blocks of data no larger than 9k.
5234 Without this, mod_include will wait until the whole file is parsed,
5235 or the first tag is found to send any data to the client.
5236 [Paul J. Reder <rederpj raleigh.ibm.com>]
5238 *) Fix mod_info, so that <Directory> and <Location> directives are
5239 not displayed twice when displaying the current configuration.
5240 [Ryan Morgan <rmorgan covalent.net>]
5242 *) Add config directives to override DEFAULT_ERROR_MSG and
5243 DEFAULT_TIME_FORMAT. This was sent in as PR 6193.
5244 [Dan Rench <drench xnet.com>]
5246 *) Get mod_info building and loading on Win32. [William Rowe]
5248 *) Begin to move protocol independant functions out of mod_http. The goal
5249 is to have only functions that are HTTP specific in the http directory.
5252 Changes with Apache 2.0.13
5254 *) Don't assume that there will always be multiple calls to the byterange
5255 filter. It is possible that we will need to do byteranges with only
5256 one call to the filter. [Ryan Morgan <rmorgan covalent.net>]
5258 *) Move the error_bucket definition from the http module to the
5259 core server. Every protocol will need this ability, not just
5262 Changes with Apache 2.0.12
5264 *) Modify mod_file_cache to save pre-formatted strings for
5265 content-length and last-modified headers for performance.
5266 [Mike Abbot <mja trudge.engr.sgi.com>]
5268 *) Namespace protect IOBUFSIZ since it is exposed in the API.
5269 [Jon Travis <jtravis covalent.net>]
5271 *) Use "Basic" authentication instead of "basic" in ab, as the spec
5272 says we should. [Andre Breiler <andre.breiler rd.bbc.co.uk>]
5274 *) Fix a seg fault in mod_userdir.c. We used to use the pw structure
5275 without ever filling it out. This fixes PR 7271.
5276 [Taketo Kabe <kabe sra-tohoku.co.jp> and
5277 Cliff Woolley <cliffwoolley yahoo.com>]
5279 *) Add a couple of GCC attribute tags to printf style functions.
5280 [Jon Travis <jtravis covalent.net>]
5282 *) Add the correct language tag for interoperation with the Taiwanese
5283 versions of MSIE and Netscape. [Clive Lin <clive CirX.ORG>] PR#7142
5285 *) Migrate the perchild MPM to use the new apr signal child, and
5286 APR thread functions. [Ryan Bloom]
5288 *) Close one copy of the CGI's stdout before creating the new process.
5289 The CGI will still have stdout, because we have already dup'ed it.
5290 This keeps Apache from waiting forever to send the results of a CGI
5291 process that has forked a long-lived child process.
5292 [Taketo Kabe <kabe sra-tohoku.co.jp>]
5294 *) Remove the rest of the pthreads functions from the threaded MPM.
5295 This requires the APR support for a signal thread that was just
5298 *) Make mod_dir use a fixup for sending a redirect to the browser.
5299 Before this, we were using a handler, which doesn't make much
5300 sense, because the handler wasn't generating any data, it would
5301 either return a redirect error code, or DECLINED. This fits the
5302 current hooks better. [Ryan Morgan <rmorgan covalent.net>]
5304 *) Make the threaded MPM use APR threads instead of pthreads.
5307 *) Get mod_tls to the point where it actually appears to work in all cases.
5310 *) implement --enable-modules and --enable-mods-shared for "all" and
5311 "most". [Greg Stein]
5313 *) Move the threaded MPM to use APR locks instead of pthread locks.
5316 *) Rename mpmt_pthread to threaded. This is more in line with the
5317 fact that mpmt_pthread shouldn't be using pthreads directly, and
5318 it is a smaller name that doesn't tie into anything.
5321 *) Rename the module structures so that the exported symbol matches
5322 the file name, and it is easier to automate the installation
5323 process (generating LoadModule directives from the module filenames).
5326 *) Remove the coalesce filter. With the ap_f* functions, this filter
5327 is no longer needed. [Ryan Bloom]
5329 Changes with Apache 2.0.11
5331 *) Remove the dexter MPM. Perchild is the same basic idea, but it has the
5332 added feature of allowing a uid/gid per child process. If no
5333 uid/gid is specified, then Perchild behaves exactly like dexter.
5336 *) Get perchild building again. [Ryan Bloom]
5338 *) Don't disable threads just because we are using the prefork MPM.
5339 If somebody wants to compile without threads, they must now add
5340 --disable-threads to the configure command line. [Ryan Bloom]
5342 *) Begin to move the calls to update_child_status into common code, so
5343 that each individual MPM does not need to update the scoreboard itself.
5346 *) Allow mod_tls to compile under Unix boxes where openssl has been
5347 installed to the system include files.
5348 [Gomez Henri <new-httpd slib.fr>]
5350 *) Cleanup the mod_tls configure process. This should remove any need
5351 to hand-edit any files. We require OpenSSL 0.9.6 or later, but
5352 configure doesn't check that yet. [Ryan Bloom]
5354 *) Add a very early prototype of SSL support (in mod_tls.c). It is
5355 vital that you read modules/tls/README before attempting to build
5358 *) Fix a potential seg fault on all platforms. David Reid fixed this
5359 on BEOS, but the problem could happen anywhere, so we don't want
5360 to #ifdef it. [Cliff Woolley <cliffwoolley yahoo.com>]
5362 *) Add new LogFormat directive, %D, to log time it takes to serve a
5363 request in microseconds. [Bill Stoddard]
5365 *) Change AddInputFilter and AddOutputFilter to SetInputFilter and
5366 SetOutputFilter. This corresponds nicely with the other Set
5367 directives, which operate on containers while the Add* directives
5368 tend to work directly on extensions. [Ryan Bloom]
5370 *) Cleanup the header handling a bit. This uses the apr_brigade_*
5371 functions for the buffering so that we don't need to compute
5372 the length of the headers before we actually create the header
5373 buffer. [Ryan Bloom]
5375 *) Allow filters to buffer data using the ap_f* functions. These have
5376 become macros that resolve directly to apr_brigade_*.
5379 *) Get the Unix MPM's to do a graceful restart again. If we are going
5380 to register a cleanup with ap_cleanup_scoreboard, then we have to
5381 kill the cleanup with the same function, and that function can't be
5382 static. [Ryan Bloom]
5384 *) Install all required header files. Without these, it was not
5385 possible to compile some modules outside of the server.
5388 *) Fix the AliasMatch directive in Apache 2.0. When we brought a patch
5389 forward from 1.3 to 2.0, we missed a single line, which broke regex
5390 aliases. [Ryan Bloom]
5392 *) We have a poor abstraction in the protocol. This is a temporary
5393 hack to fix the bug, but it will need to be fixed for real. If
5394 we find an error while sending out a custom error response, we back
5395 up to the first non-OK request and send the data. Then, when we send
5396 the EOS from finalize_request_protocol, we go to the last request,
5397 to ensure that we aren't sending an EOS to a request that has already
5398 received one. Because the data is sent on a different request than
5399 the EOS, the error text never gets sent down the filter stack. This
5400 fixes the problem by finding the last request, and sending the data
5401 with that request. [Ryan Bloom]
5403 *) Make the server status page show the correct restart time, and
5404 thus the proper uptime. [Ryan Bloom]
5406 *) Move the CGI creation logic from mod_include to mod_cgi(d). This
5407 should reduce the amount of duplicate code that is required to
5408 create CGI processes.
5409 [Paul J. Reder <rederpj raleigh.ibm.com>]
5411 *) ap_new_connection() closes the socket and returns NULL if a socket
5412 call fails. Usually this is due to a connection which has been
5413 reset. [Jeff Trawick]
5415 *) Move the Apache version information out of httpd.h and into release.h.
5416 This is in preparation for the first tag with the new tag and release
5417 system. [Ryan Bloom]
5419 *) Begin restructuring scoreboard code to enable adding back in
5420 the ability to use IPC other than shared memory.
5421 Get mod_status working on Windows again. [Bill Stoddard]
5423 *) Make mod_status work with 2.0. This will work for prefork,
5424 mpmt_pthread, and dexter. [Ryan Bloom]
5426 *) Correct a typo in httpd.conf.
5427 [Kunihiro Tanaka <tanaka apache.or.jp>] PR#7154
5429 *) Really fix mod_rewrite map lookups this time. [Tony Finch]
5431 *) Get the correct IP address if ServerName isn't set and we can't
5432 find a fully-qualified domain name at startup.
5433 PR#7170 [Danek Duvall <dduvall eng.sun.com>]
5435 *) Make mod_cgid work with SuExec. [Ryan Bloom]
5437 *) Adopt apr user/group name features for mod_rewrite. Eliminates some
5438 'extra' stat's for user/group since they should never occur, and now
5439 resolves the SCRIPT_USER and SCRIPT_GROUP, including on WinNT NTFS
5440 volumes. [William Rowe]
5442 *) Adopt apr features to simplify mod_includes. This changes the
5443 behavior of the USER_NAME variable, unknown uid's are now reported
5444 as USER_NAME="<unknown>" rather than the old user#000 result.
5445 WinNT now resolves USER_NAME on NTFS volumes. [William Rowe]
5447 *) Adopt apr features for simplifing mod_userdir, and accept the new
5448 Win32/OS2 exceptions without hiccuping. [William Rowe]
5450 *) Replace configure --with-optim option by using and saving the
5451 environment variable OPTIM instead. This is needed because configure
5452 options do not support multiple flags separated by spaces.
5455 *) Fix some byterange handling. If we get a byte range that looks like
5456 "-999999" where that is past the end of the file, we should return
5457 a PARTIAL CONTENT status code, and return the whole file as one big
5458 byterange. This matches the 1.3 handling now. [Ryan Bloom]
5460 *) Make the error bucket a real meta-data bucket. This means that the
5461 bucket length is 0, and a read returns NULL data. If one of these
5462 buckets is passed down after the headers are sent, this data will
5463 just be ignored. [Greg Stein]
5465 *) The prefork MPM wasn't killing child processes correctly if a restart
5466 signal was received while the process was serving a request. The child
5467 process would become the equivalent of a second parent process. If
5468 we break out of the accept loop, then we need to do die after cleaning
5469 up after ourselves. [Ryan Bloom]
5471 *) Change the Prefork MPM to use SIGWINCH instead of SIGUSR1 for graceful
5472 restarts. [Ryan Bloom]
5474 *) Modify the apr_stat/lstat/getfileinfo calls within apache to use
5475 the most optimal APR_FINFO_wanted bits. This spares Win32 from
5476 performing very expensive owner, group and permission lookups
5477 and allows the server to function until these apr_finfo_t fields
5478 are implemented under Win32. [William Rowe]
5480 *) Support for typedsafe optional functions - that is functions exported by
5481 optional modules, which, therefore, may or may not be present, depending
5482 on configuration. See the experimental modules mod_optional_fn_{ex,im}port
5483 for sample code. [Ben Laurie]
5485 *) filters can now report an HTTP error to the server. This is done
5486 by sending a brigade where the first bucket is an error_bucket.
5487 This bucket is a simple bucket that stores an HTTP error and
5488 a string. Currently the string is not used, but it may be needed
5489 to output an error log. The http_header_filter will find this
5490 bucket, and output the error text, and then return
5491 AP_FILTER_ERROR, which informs the server that the error web page
5492 has already been sent. [Ryan Bloom]
5494 *) If we get an error, then we should remove all filters except for
5495 those critical to serving a web page. This fixes a bug, where
5496 error pages were going through the byterange filter, even though
5497 that made no sense. [Ryan Bloom]
5499 *) Relax the syntax checking of Host: headers in order to support
5500 iDNS. PR#6635 [Tony Finch]
5502 *) Cleanup the byterange filter to use the apr_brigade_partition
5503 and apr_bucket_copy functions. This removes a lot of very messy
5504 code, and hopefully makes this filter more stable.
5507 *) Remove AddModule and ClearModuleList directives. Both of these
5508 directives were used to ensure that modules could be enabled
5509 in the correct order. That requirement is now gone, because
5510 we use hooks to ensure that modules are in the correct order.
5513 *) When SuExec is specified, we need to add it to the list of
5514 targets to be built. If we don't, then any changes to the
5515 configuration won't affect SuExec, unless 'make suexec' is
5516 specifically run. [Ryan Bloom]
5518 *) Cleaned out open_file from mod_file_cache, as apr now accepts
5519 the APR_XTHREAD argument to open a file for consumption by
5520 parallel threads on win32. [William Rowe]
5522 *) Correct a bug in determining when we follow symlinks. The code
5523 expected a stat -1 result, not an apr_status_t positive error.
5524 Also check if the APR_FINFO_USER fields are valid before we
5525 follow the link. [William Rowe]
5527 *) Move initgroupgs, ap_uname2id and ap_gname2id from util.c to
5528 mpm_common.c. These functions are only valid on some platforms,
5529 so they should not be in the main-line code. [Ryan Bloom]
5531 *) Remove ap_chdir_file(). This function is not thread-safe,
5532 and nobody is currently using it. [Ryan Bloom]
5534 *) Do not try to run make depend if there are no .c files in the
5535 current directory, doing so makes `make depend` fail.
5538 *) Update highperformance.conf to work with either prefork or
5539 pthreads mpms. [Greg Ames]
5541 *) Stop checking to see if this is a pipelined request if we know
5542 for a fact that it isn't. Basically, if r->connection->keepalive == 0.
5543 This keeps us from making an extra read call when serving a 1.0
5544 request. [Ryan Bloom and Greg Stein]
5546 *) Fix the handling of variable expansion look-ahead in mod_rewrite,
5547 i.e. syntax like %{LA-U:REMOTE_USER}, and also fix the parsing of
5548 more complicated nested RewriteMap lookups. PR#7087 [Tony Finch]
5550 *) Fix the RFC number mentioned when complaining about a missing
5551 Host: header. PR#7079 [Alexey Toptygin <alexeyt wam.umd.edu>]
5553 *) Fix an endless loop in ab which occurred when ab was posting
5554 and the server dropped the connection unexpectedly.
5557 *) Fix a segfault while handling request bodies in ap_http_filter().
5558 This problem has been seen with mod_dav usage as well as with
5559 requests where the body was just being discarded. [Jeff Trawick]
5561 *) Some adjustment on the handling and automatic setting (via
5562 hints.m4) of various compilation flags (eg: CFLAGS). Also,
5563 add the capability to specify flags (NOTEST_CFLAGS and
5564 NOTEST_LDFLAGS) which are used to compile Apache, but
5565 not used during the configuration process. Useful for
5566 flags like "-Werror". [Jim Jagielski]
5568 *) Stop using environment variables to force debug mode or
5569 no detach. We now use the -D command line argument to
5570 specify the correct mode. -DONE_PROCESS and -DNO_DETACH.
5571 [Greg Stein, Ryan Bloom]
5573 *) Change handlers to use hooks. [Ben Laurie]
5575 *) Stop returning copies of filenames from both apr_file_t and
5576 apr_dir_t. We pstrdup the filenames that we store in the
5577 actual structures, so we don't need to pstrdup the strings again.
5580 *) mod_cgi: Fix some problems where the wrong error value was being
5581 traced. [Jeff Trawick]
5583 *) EBCDIC: Fix some missing ASCII conversion on some protocol data.
5586 *) Add generic hooks. [Ben Laurie]
5588 *) Use a real pool to dup the error log descriptor. [Ryan Bloom]
5590 *) Fix a segfault caused by mod_ext_filter when the external filter
5591 program does not exist. [Jeff Trawick]
5593 *) Fix an output truncation error when on an HTTP >= 1.0 request an
5594 object of size between DEFAULT_BUCKET_SIZE and AP_MIN_BYTES_TO_WRITE
5595 was served through mod_charset_lite (or anything else that would
5596 create a transient bucket in this size range). ap_bucket_make_heap()
5597 silently failed (fixed), transient_setaside() discovered it, but
5598 ap_save_brigade() ignored it (fixed). [Jeff Trawick]
5600 *) Ignore \r\n or \n when using PEEK mode for input filters. The problem
5601 is that some browsers send extra lines at the end of POST requests, and
5602 we don't want to delay sending data back to the user just because the
5603 browser isn't well behaved. [Ryan Bloom]
5605 *) Get SuEXEC working again. We can't send absolute paths to suExec
5606 because it refuses to execute those programs. SuEXEC also wasn't
5607 always recognizing configuration changes made using the autoconf
5610 *) Allow the buildconf process to find the config.m4 files in the correct
5611 order. Basically, we can now name config.m4 files as config\d\d.m4,
5612 and we will sort them correctly when inserting them into the build
5613 process. [Ryan Bloom]
5615 *) Get mod_cgid to use apr calls for creating the actual CGI process.
5616 This also allows mod_cgid to use ap_os_create_priviledged_process,
5617 thus allowing for SuExec execution from mod_cgid. Currently, we do
5618 not support everything that standard SuExec supports, but at least
5619 it works minimally now. [Ryan Bloom]
5621 *) Allow SuExec to be configured from the ./configure command line.
5624 *) Update some of the docs in README and INSTALL to reflect some of
5625 the changes in Apache 2.0 [Cliff Woolley <cliffwoolley yahoo.com>]
5627 *) If we get EAGAIN returned from the call to apr_sendfile, then we
5628 need to call sendfile again. This gets us serving large files
5629 such as apache_2.0a9.tar.gz on FreeBSD again. [Ryan Bloom]
5631 *) Get the support programs building cleanly again.
5632 [Cliff Woolley <cliffwoolley yahoo.com>]
5634 *) The Apache/Win32 Apache.exe and dll's now live in bin. The
5635 current directory logic now backs up over bin/ to determine the
5636 server root from the Apache.exe path.
5638 *) Apache/Win32 now follows the standard conventions of mod_foo.so
5639 loadable modules, dynamic libs are all named libfoo.dll, and the
5640 makefile.win populates the include, lib and libexec directories.
5642 *) Apache is now IPv6-capable. On systems where APR supports IPv6,
5643 Apache gets IPv6 listening sockets by default. Additionally, the
5644 Listen, NameVirtualHost, and <VirtualHost> directives support IPv6
5645 numeric address strings (e.g., "Listen [fe80::1]:8080").
5648 *) Modify the install directory layout. Modules are now installed in
5649 modules/. Shared libraries should be installed in libraries/, but
5650 we don't have any of those on Unix yet. All install directories
5651 are modifyable at configure time. [Ryan Bloom]
5653 *) Install all header files in the same directory on Unix. [Ryan Bloom]
5655 *) Get the functions in server/linked into the server, regardless of
5656 which modules linked into the server. This uses the same hack
5657 for Apache that we use for APR and apr-util to ensure all of the
5658 necessary functions are linked. As a part of thise, the CHARSET_EBCDIC
5659 was renamed to AP_CHARSET_EBCDIC for namespace protection, and to make
5660 the scripts a bit easier.
5663 *) Rework the RFC1413 handling to make it thread-safe, use a timeout
5664 on the query, and remove IPv4 dependencies. [Jeff Trawick]
5666 *) Get all of the auth modules to the point that they will install and
5667 be loadable into the server. Our new build/install mechanism expects
5668 that all modules will have a common name format. The auth modules
5669 didn't use that format, so we didn't install them properly.
5672 *) API routines ap_pgethostbyname() and ap_pduphostent() are no longer
5673 available. Use apr_getaddrinfo() instead. [Jeff Trawick]
5675 *) Get "NameVirtualHost *" working in 2.0. [Ryan Bloom]
5677 *) Return HTTP_RANGE_NOT_SATISFIABLE if the every range requested starts
5678 after the end of the response. [Ryan Bloom]
5680 *) Get byterange requests working with responses that do not have a
5681 content-length. Because of the way byterange requests work, we have to
5682 have all of the data before we can actually do the byterange, so we
5683 can compute the content-length in the byterange filter.
5686 *) Get exe CGI's working again on Windows.
5689 *) Get mod_cgid and mod_rewrite to work as DSOs by changing the way
5690 they keep track of whether or not their post config hook has been
5691 called before. Instead of a static variable (which is replaced when
5692 the DSO is loaded a second time), use userdata in the process pool.
5695 Changes with Apache 2.0a9
5697 *) Win32 now requires perl to complete the final install step for users
5698 to build + install on Win32. Makefile.win now rewrites @@ServerRoot@
5699 and installs the conf, htdocs and htdocs/manual directories.
5702 *) Make mod_include use a hash table to associate directive tags with
5703 functions. This allows modules to implement their own SSI tags easily.
5704 The idea is simple enough, a module can insert it's own tag and function
5705 combination into a hash table provided by mod_include. While mod_include
5706 parses an SSI file, when it encounters a tag in the file, it does a
5707 hash lookup to find the function that implements that tag, and passes
5708 all of the relevant data to the function. That function is then
5709 responsible for processing the tag and handing the remaining data back
5710 to mod_include for further processing.
5711 [Paul J. Reder <rederpj raleigh.ibm.com>]
5713 *) Get rid of ap_new_apr_connection(). ap_new_connection() now has
5714 fewer parameters: the local and remote socket addresses were removed
5715 from the parameter list because all required information is available
5716 via the APR socket. [Jeff Trawick]
5718 *) Distribution directory structure reorganized to reflect a
5719 normal source distribution with external install targets.
5722 *) The MPMs that need multiple segments of shared memory now create
5723 two apr_shmem_t variables, one for each shared memory allocation.
5724 the problem is that we can't determine how much memory will be required
5725 for shared memory allocations once we try to allocate more than one
5726 variable. The MM code automatically aligns the shared memory allocations,
5727 so we end up needing to pad the amount of shared memory we want based
5728 on how many variables will be allocated out of the shared memory segment.
5729 It is just easier to create a second apr_shmem_t variable, and two
5730 shmem memory blocks.
5733 *) Cleanup the export list a bit. This creates a single unified list of
5734 functions exported by APR. The export list is generated at configure
5735 time, and that list is then used to generate the exports.c file.
5736 Because of the way the export list is generated, we only export those
5737 functions that are valid on the platform we are building on.
5740 *) Enable logging the cookie with mod_log_config
5741 [Sander van Zoest <sander covalent.net>]
5743 *) Fix a segfault in mod_info when it reaches the end of the configuration.
5746 *) Added lib/aputil/ as a placeholder for utility functions which are not
5747 specific to the Apache HTTP Server (but do not make sense with APR).
5748 The first utility is "apu_dbm": a set of functions to work with DBM
5749 files. This first version can be compiled for SDBM or GDBM databases.
5752 *) Complete re-write of mod_include. This makes mod_include a filter that
5753 uses buckets directly. This has now served the FAQ correctly.
5754 [Paul Reder <rederpj raleigh.ibm.com>]
5756 *) Allow modules to specify the first filter in a sub_request when
5757 making the sub_request. This keeps modules from having to change the
5758 output_filter immediately after creating the sub-request, and therefore
5759 skip the sub_req_output_filter. [Ryan Bloom]
5761 *) Update ab to accept URLs with IPv6 literal address strings (in the
5762 format described in RFC 2732), and to build Host header fields in
5763 the same format. This allows IPv6 literal address strings to be
5764 used with ab. This support has been tested against Apache 1.3 with
5765 the KAME patch, but Apache 2.0 does not yet work with this format
5766 of the Host header field. [Jeff Trawick]
5768 *) Accomodate an out-of-space condition in the piped logs and the
5769 rotatelogs.c code, and no longer churn log processes for this
5770 condition. [Victor J. Orlikowski]
5772 *) Add support for partial writes with apr_sendfile() to core_output_filter.
5775 Changes with Apache 2.0a8
5777 *) Add a directive to mod_mime so that filters can be associated with
5781 *) Get multi-views working again. We were setting the path_info
5782 field incorrectly if we couldn't find the specified file.
5785 *) Fix 304 processing. The core should never try to send the headers
5786 down the filter stack. Always, just setup the table in the request
5787 record, and let the header filter convert it to data that is ready
5791 *) More fixes for the proxy. There are still bugs in the proxy code,
5792 but this has now proxied www.yahoo.com and www.ntrnet.net (my ISP)
5796 *) Fix params for apr_getaddrinfo() call in connect proxy handler.
5799 *) APR: Add new apr_getopt_long function to handle long options.
5800 [B. W. Fitzpatrick <fitz red-bean.com>]
5802 *) APR: Change apr_connect() to take apr_sockaddr_t instead of hostname.
5803 Add generic apr_create_socket(). Add apr_getaddrinfo() for doing
5804 hostname resolution/address string parsing and building
5805 apr_sockaddr_t. Add apr_get_sockaddr() for getting the address
5806 of one of the apr_sockaddr_t structures for a socket. Change
5807 apr_bind() to take apr_sockaddr_t. [David Reid and Jeff Trawick]
5809 *) Remove the BUFF from the HTTP proxy. This is still a bit ugly, but
5810 I have proxied pages with it, cleanup will commence soon.
5813 *) Make the proxy work with filters. This isn't perfect, because we
5814 aren't dealing with the headers properly. [Ryan Bloom]
5816 *) Do not send a content-length iff the C-L is 0 and this is a head
5817 request. [Ryan Bloom]
5819 *) Make cgi-bin work as a regular directory when using mod_vhost_alias
5820 with no VirtualScriptAlias directives. PR#6829 [Tony Finch]
5822 *) Remove BUFF from the PROXY connect handling. [Ryan Bloom]
5824 *) Get the default_handler to stop trying to deal with HEAD requests.
5825 The idea is to let the content-length filter compute the C-L before
5826 we try to send the data. If we can get the C-L correctly, then we
5827 should send it in the HEAD response.
5830 *) The Header filter can now determine if a body should be sent based
5831 on r->header_only. The general idea of this is that if we delay
5832 deciding to send the body, then we might be able to compute the
5833 content-length correctly, which will help caching proxies to cache
5834 our data better. Any handler that doesn't want to try to compute
5835 the content-length can just send an EOS bucket without data and
5836 everything will just work.
5839 *) Add the referer to the error log if one is available.
5840 [Markus Gyger <mgyger itr.ch>]
5842 *) Mod_info.c has now been ported to Apache 2.0. As a part of this
5843 change, the root of the configuration tree has been exposed to modules
5845 [Ryan Morgan <rmorgan covalent.net>]
5847 *) Get the core_output_filter to use the bucket interface directly.
5848 This keeps us from calling the content-length filter multiple times
5849 for a simple static request.
5852 *) We are sending the content-type correctly now.
5853 [Ryan Bloom and Will Rowe]
5855 *) APR on FreeBSD: Fix a bug in apr_sendfile() which caused us to report
5856 a bogus bytes-sent value when the only thing being sent was trailers
5857 and writev() returned an error (or EAGAIN). [Jeff Trawick]
5859 *) Get SINGLE_LISTEN_UNSERIALIZED_ACCEPT working again. This uses the
5860 hints file to determine which platforms define
5861 SINGLE_LISTEN_UNSERIALIZED_ACCEPT.
5864 *) APR: add apr_get_home_directory() [Jeff Trawick]
5866 *) Initial import of 1.3-current mod_proxy. [Chuck Murcko]
5868 *) Not all platforms have INADDR_NONE defined by default. Apache
5869 used to make this check and define INADDR_NONE if appropriate,
5870 but APR needs the check too, and I suspect other applications will
5871 as well. APR now defines APR_INADDR_NONE, which is always a valid
5872 value on all platforms.
5873 [Branko Èibej <brane xbc.nu>]
5875 *) Destroy the pthread mutex in lock_intra_cleanup() for PR#6824.
5876 [Shuichi Kitaguchi <ki hh.iij4u.or.jp>]
5878 *) Relax the syntax checking of Host: headers in order to support
5879 iDNS. PR#6635 [Tony Finch]
5881 *) When reading from file buckets we convert to an MMAP if it makes
5882 sense. This also simplifies the default handler because the
5883 default handler no longer needs to try to create MMAPs.
5886 *) BUFF has been removed from the main server. The BUFF code will remain
5887 in the code until it has been purged from the proxy module as well.
5890 *) Byteranges have been completely re-written to be a filter. This
5891 has been tested, and I believe it is working correctly, but it could
5892 doesn't work for the Adobe Acrobat plug-in. The output almost matches
5893 the output from 1.3, the only difference being that 1.3 includes
5894 a content-length in the response, and this does not.
5897 *) APR read/write functions and bucket read functions now operate
5898 on unsigned integers, instead of signed ones. It doesn't make
5899 any sense to use signed ints, because we return the error codes,
5900 so if we have an error we should report 0 bytes read or written.
5903 *) Always compute the content length, whether it is sent or not.
5904 The reason for this, is that it allows us to correctly report
5905 the bytes_sent when logging the request. This also simplifies
5906 content-length filter a bit, and fixes the actual byte-reporing
5907 code in mod_log_config.c
5910 *) Remove AP_END_OF_BRIGADE definition. This does not signify what
5911 it says, because it was only used by EOS and FLUSH buckets. Since
5912 neither of those are required at the end of a brigade, this was
5913 really signifying FLUSH_THE_DATA, but that can be determined better
5914 by checking AP_BUCKET_IS_EOS() or AP_BUCKET_IS_FLUSH. EOS and FLUSH
5915 buckets now return a length of 0, which is actually the amount of data
5916 read, so they make more sense.
5919 *) Allow the core_output_filter to save some data past the end of a
5920 request. If we get an EOS bucket, we only send the data if it
5921 makes sense to send it. This allows us to pipeline request
5922 responses. As a part of this, we also need to allocate mmap
5923 buckets out of the connection pool, not the request pool. This
5924 allows the mmap to outlive the request.
5927 *) Make blocking and non-blocking bucket reads work correctly for
5928 sockets and pipes. These are the only bucket types that should
5929 have non-blocking reads, because the other bucket types should
5930 ALWAYS be able to return something immediately.
5933 *) In the Apache/Win32 console window, accept Ctrl+C to stop the
5934 server, but use Ctrl+Break to initiate a graceful restart
5935 instead of duplicating behavior. [John Sterling]
5937 *) Patch mod_autoindex to set the Last-Modified header based on
5938 the directory's mtime, and add the ETag header. [William Rowe]
5940 *) Merge the 1.3 patch to add support for logging query string in
5941 such a way that "%m %U%q %H" is the same as "%r".
5944 *) Port three log methods from mod_log_config 1.3 to 2.0:
5945 CLF compliant '-' byte count, method and protocol.
5948 *) Add a new LogFormat directive, %c, that will log connection
5949 status at the end of the response as follows:
5950 'X' - connection aborted before the response completed.
5951 '+' - connection may be kept-alive by the server.
5952 '-' - connection will be closed by the server.
5955 *) Expand APR for WinNT to fully accept and return utf-8 encoded
5956 Unicode file names and paths for Win32, and tag the Content-Type
5957 from mod_autoindex to reflect that charset if the feature
5958 macro APR_HAS_UNICODE_FS is true. [William Rowe]
5960 *) Compute the content length (and add appropriate header field) for
5961 the response when no content length is available and we can't use
5962 chunked encoding. [Jeff Trawick]
5964 *) Changed ap_discard_request_body() to use REQUEST_CHUNKED_DECHUNK,
5965 so that content input filters get dechunked data when using
5966 the default handler. Also removed REQUEST_CHUNKED_PASS.
5969 *) Add mod_ext_filter as an experimental module. This module allows
5970 the administrator to use external programs as filters. Currently,
5971 only filtering of output is supported. [Jeff Trawick]
5973 *) Most Apache functions work on EBCDIC machines again, as protocol
5974 data is now translated (again). [Jeff Trawick]
5976 *) Introduce ap_xlate_proto_{to|from}_ascii() to clean up some of
5977 the EBCDIC support. They are noops on ASCII machines, so this
5978 type of translation doesn't have to be surrounded by #ifdef
5979 CHARSET_EBCDIC. [Jeff Trawick]
5981 *) Fix mod_include. tag commands work again, and the server will
5982 send the FAQ again. This also allows mod_include to set aside
5983 buckets that include partial buckets.
5984 [Ryan Bloom and David Reid]
5986 *) Add suexec support back. [Manoj Kasichainula]
5988 *) Lingering close now uses the socket directly instead of using
5989 BUFF. This has been tested, but since all we can tell is that it
5990 doesn't fail, this needs to be really hacked on.
5993 *) Allow filters to modify headers and have those headers be sent to
5994 the client. The idea is that we have an http_header filter that
5995 actually sends the headers to the network. This removes the need
5996 for the BUFF to send headers.
5999 *) Charset translation: mod_charset_lite handles translation of
6000 request bodies. Get rid of the xlate version of ap_md5_digest()
6001 since we don't compute digests of filtered (e.g., translated)
6002 response bodies this way anymore. (Note that we don't do it at
6003 all at the present; somebody needs to write a filter to do so.)
6006 *) Input filters and ap_get_brigade() now have a input mode parameter
6007 (blocking, non-blocking, peek) instead of a length parameter.
6010 *) Update the mime.types file to the registered media types as
6011 of 2000-10-19. PR#6613 [Carsten Klapp <carsten.klapp home.net>,
6014 *) Namespace protect some macros declared in ap_config.h
6017 *) Support HTTP header line folding with input filtering.
6020 *) Mod_include works again. This should still be re-written, but at
6021 least now we can serve an SHTML page again.
6024 *) Begin to remove BUFF from the core. Currently, we keep a pointer
6025 to both the BUFF and the socket in the conn_rec. Functions that
6026 want to use the BUFF can, functions that want to use the socket,
6027 can. They point to the same place.
6030 *) apr_psprintf doesn't understand %lld as a format. Make it %ld.
6031 [Tomas "Ögren" <stric ing.umu.se>]
6033 *) APR pipes on Unix and Win32 are now cleaned up automatically when the
6034 associated pool goes away. (APR pipes on OS/2 were already had this
6035 logic.) This resolvs a fatal file descriptor leak with CGIs.
6038 *) The final line of the config file was not being read if there was
6039 no \n at the end of it. This was caused by apr_fgets returning
6040 APR_EOF even though we had read valid data. This is solved by
6041 making cfg_getline check the buff that was returned from apr_fgets.
6042 If apr_fgets return APR_EOF, but there was data in the buf, then we
6043 return the buf, otherwise we return NULL.
6046 *) Piped logs work again in the 2.0 series.
6049 *) Restore functionality broken by the mod_rewrite security fix:
6050 rewrite map lookup keys and default values are now expanded
6051 so that the lookup can depend on the requested URI etc.
6052 PR #6671 [Tony Finch]
6054 *) SECURITY: Tighten up the syntax checking of Host: headers to fix a
6055 security bug in some mass virtual hosting configurations
6056 that can allow a remote attacker to retrieve some files
6057 on the system that should be inaccessible. [Tony Finch]
6059 *) Add a pool bucket type. This bucket is used for data allocated out
6060 of a pool. If the pool is cleaned before the bucket is destroyed, then
6061 the data is converted to a heap bucket, allowing it to survive the
6065 *) Add a flush bucket. This allows modules to signal that the filters
6066 should all flush whatever data they currently have. There is no way
6067 to actually force them to do this, so if a filter ignores this bucket,
6068 that's life, but at least we can try with this.
6071 *) Add an output filter for sub-requests. This filter just strips the
6072 EOS bucket so that we don't confuse the main request's core output
6073 filter by sending multiple EOS buckets. This change also makes sub
6074 requests start to send EOS buckets when they are finished.
6077 *) Make ap_bucket_(read|destroy|split|setaside) into macros. Also
6078 makes ap_bucket_destroy a return void, which is okay because it
6079 used to always return APR_SUCCESS, and nobody ever checked its
6080 return value anyway.
6081 [Cliff Woolley <cliffwoolley yahoo.com>]
6083 *) Remove the index into the bucket-type table from the buckets
6084 structure. This has now been replaced with a pointer to the
6085 bucket_type. Also add some macros to test the bucket-type.
6088 *) Renamed all MODULE_EXPORT symbols to AP_MODULE_DECLARE and all symbols
6089 for CORE_EXPORT to AP_CORE_DECLARE (namespace protecting the wrapper)
6090 and retitled API_EXPORT as AP_DECLARE and APR_EXPORT as APR_DECLARE.
6091 All _VAR_ flavors changes to _DATA to be absolutely clear.
6094 *) Add support for /, //, //servername and //server/sharename
6095 parsing of <Directory> blocks under Win32 and OS2.
6096 [Tim Costello, William Rowe, Brian Harvard]
6098 *) Remove the function pointers from the ap_bucket type. They have been
6099 replaced with a global table. Modules are allowed to register bucket
6100 types and use then use those buckets.
6103 *) mod_cgid: In the handler, shut down the Unix socket (only for write)
6104 once we finish writing the request body to the cgi child process;
6105 otherwise, the client doesn't hit EOF on stdin. Small request bodies
6106 worked without this change (for reasons I don't understand), but large
6107 ones didn't. [Jeff Trawick]
6109 *) Remove file bucket specific information from the ap_bucket type.
6110 This has been moved to a file_bucket specific type that hangs off
6111 the data pointer in the ap_bucket type.
6114 *) Input filtering now has a third argument. This is the amount of data
6115 to read from lower filters. This argument can be -1, 0, or a positive
6116 number. -1 means give me all the data you have, I'll deal with it and
6117 let you know if I need more. 0 means give me one line and one line
6118 only. A positive number means I want no more than this much data.
6120 Currently, only 0 and a positive number are implemented. This allows
6121 us to remove the remaining field from the conn_rec structure, which
6125 *) Big cleanup of the input filtering. The goal is that http_filter
6126 understands two conditions, headers and body. It knows where it is
6127 based on c->remaining. If c->remaining is 0, then we are in headers,
6128 and http_filter returns a line at a time. If it is not 0, then we are
6129 in body, and http_filter returns raw data, but only up to c->remaining
6130 bytes. It can return less, but never more.
6131 [Greg Ames, Ryan Bloom, Jeff Trawick]
6133 *) mod_cgi: Write all of the request body to the child, not just what
6134 the kernel would accept on the first write. [Jeff Trawick]
6136 *) Back out the change that moved the brigade from the core_output_filters
6137 ctx to the conn_rec. Since all requests over a given connection
6138 go through the same core_output_filter, the ctx pointer has the
6142 *) Fix another bug in the send_the_file() read/write loop. A partial
6143 send by apr_send would cause unsent data in the read buffer to
6144 get clobbered. Complete making send_the_file handle partial
6145 writes to the network.
6148 *) Fix a couple of type fixes to allow compilation on AIX again
6149 [Victor J. Orlikowski <v.j.orlikowski gte.net>]
6151 *) Fix bug in send_the_file() which causes offset to be ignored
6152 if there are no headers to send.
6155 *) Handle APR_ENOTIMPL returned from apr_sendfile in the core
6156 filter. Useful for supporting Windows 9* with a binary
6157 compiled on Windows NT.
6160 Changes with Apache 2.0a7
6162 *) Reimplement core_output_filter to buffer/save bucket brigades
6163 across multiple calls to the core_filter. The brigade will be
6164 sent when either MIN_BYTES_TO_SEND or MAX_IOVEC_TO_WRITE
6165 thresholds are hit or the EOS bucket is received.
6168 *) Create experimental filter (buffer_filter) that coalesces bytes
6169 into one large buffer before invoking the next filter in the
6170 chain. This filter is particularly useful with the current
6171 implementation of mod_autoindex when it inserted above the
6172 chunk_filter. mod_autoindex generates a lot of brigades that
6173 containing buckets holding just a few bytes each. The
6174 buffer_filter coalesces these buckets into a single large bucket.
6177 *) Add apr_sendfile() support into the core_output_filter.
6180 *) Add apr_sendv() support into the core_output_filter.
6183 *) Fix mod_log_config so that it compiles cleanly with BUFFERED_LOGS
6184 [Mike Abbott <mja sgi.com>]
6186 *) Remove ap_send_fb. This is no longer used in Apache, and it doesn't
6187 make much sense, because Apache uses buckets instead of BUFFs now.
6190 *) send_the_file now falls back to a read/write loop on platforms that
6191 do not have sendfile.
6192 [Ryan Bloom and Brian Havard]
6194 *) Install apachectl correctly, and substitute the proper values so
6195 that it works again. [Ryan Bloom]
6197 *) Better(??) handle platforms that lack sendfile().
6200 *) APR now has UUID generation/formatting/parsing support.
6203 *) Begin the http_filter. This is an input filter that understands
6204 the absolute basic amount required to parse an HTTP Request. The
6205 goal is to be able to split headers from request body before passing
6206 the data back to the other filters.
6209 *) Bring forward from 1.3.13 the config directory implementation
6212 *) install apxs if it is created
6215 *) Added APR_IS_STATUS_condition test macros to eliminate canonical error
6216 conversions. [William Rowe]
6218 *) Now that we have ap_add_input_filter(), rename ap_add_filter() to
6219 ap_add_output_filter(). [Jeff Trawick]
6221 *) Multiple build and configuration fixes
6224 -add datadir and localstatedir substitutions
6226 -fix logfilename misspelling
6227 -fix evaluation of installation dir variables and
6228 -replace $foobar by $(foobar) to be usefull in the makefile
6232 -add rules for cross-compiling in rules.mk. Okay, rule to check for
6233 $CC_FOR_BUILD is still missing
6234 -use CHECK_TOOL instead of CHECK_PROG for ranlib
6235 -add missing "AR=@AR@" to severaly Makefile.in's
6236 -cache result for "struct rlimit"
6237 -compile all helper programs with native and cross compiler
6238 and use the native version to generate header file
6239 ["Rüdiger" Kuhlmann <Tadu gmx.de>]
6241 *) Prepare our autoconf setup for autoconf 2.14a and for cross-
6243 ["Rüdiger" Kuhlmann <Tadu gmx.de>]
6245 *) Fix a bug where a client which only sends \n to delimit header
6246 lines (netcat) gets a strange looking HTTP_NOT_IMPLEMENTED
6247 message. Start working on ebcdic co-existance with input
6249 [William Rowe, Greg Ames]
6251 *) If mod_so is enabled in the server always create libexec, even
6252 if there are no modules installed in this directory. This is a
6253 requirement for APXS to work correctly.
6256 *) Connection oriented output filters are now stored in the
6257 conn_rec instead of the request_rec. This allows us to add the
6258 output filter in the pre-connection phase instead of the
6259 post_read_request phase, which keeps us from trying to write an
6260 error page before we have a filter to write to the network.
6261 [Ryan Bloom, Jeff Trawick, and Greg Ames]
6263 *) Cleaning up an mmap bucket no longer deletes the mmap. An
6264 mmap can be used across multiple buckets (default_handler with
6265 byte ranges, mod_file_cache, mod_mmap_static), so cleanup of
6266 the mmap itself can't be associated with the bucket.
6269 *) Add .dll caching directive ISAPICacheFile to mod_isapi.
6272 *) Radical surgery to improve mod_isapi support under Win32.
6273 Includes a number of newer ServerSupportFunction calls, support
6274 for ReadClient (in order to retrieve POSTs greater than 48KB),
6275 and general bug fixes to more reliably load ISAPI .dll's and
6276 prevent leaking handle resources. Note: There are still
6277 discrepancies between IIS's and Apache's ServerVariables, and
6278 async calls are still not supported. Additional warnings are
6279 logged to facilitate debugging of unsupported ISAPI calls.
6282 *) Add input filtering to Apache. The basic idea for the input
6283 filters is the same as the ideas for output filters. The biggest
6284 difference is that instead of calling ap_pass_brigade, ap_get_brigade
6285 should be called, and the order of execution for the filter itself is
6286 different. When writing an output filter, a brigade is passed in,
6287 and filters operate directly on that brigade, when done, they call
6288 ap_pass_brigade. Input filters are the exact opposite. Because input
6289 is not a push operation, filters first call ap_get_brigade. When this
6290 function returns, the input filter will be left with a valid brigade.
6291 The input filter should then operate on the brigade, and return.
6294 *) Fix building on BSD/OS using its native make. The build system
6295 falls back to the BSD .include directive on that host platform.
6298 *) Expand dbmmanage to allow -d -m -s -p options for Crypt, MD5,
6299 SHA1 and plaintext password encodings. Make feature tests a
6300 bit more flexible. [William Rowe]
6302 *) Charset translation: mod_charset_lite handles output content
6303 translation in a filter. mod_charset_lite no longer ignores
6304 subrequests. A bunch of cruft related to BUFF's support for
6305 translating request and response bodies was removed.
6308 *) Move the addition of the CORE filter to the post_read_request
6309 hook in http_core.c. This removes the need to add the filter in
6310 multiple places and allows for an SSL module to be added much
6311 simpler. [Ryan Bloom]
6313 *) SECURITY: CVE-2000-0913 (cve.mitre.org)
6314 Fix a security problem that affects certain configurations of
6315 mod_rewrite. If the result of a RewriteRule is a filename that
6316 contains expansion specifiers, especially regexp backreferences
6317 $0..$9 and %0..%9, then it may be possible for an attacker to
6318 access any file on the web server. [Tony Finch]
6320 *) Fix a bug where errors that are detected during early request parsing
6321 don't produce visible HTTP error messages at the browser, because
6322 the core_filter wasn't present. [Greg Ames]
6324 *) Provide apr_socklen_t as a portability aid.
6325 [Victor J. Orlikowski]
6327 *) Overhaul of dbmmanage to allow a groups arg (as in Apache 1.2)
6328 as well as a comment arg to the add, adduser and update cmds.
6329 update allows the user to clear or preserve pw/groups/comment.
6330 Fixed a bug in dbmmanage that prevented the check option from
6331 parsing a password followed by :group... text. Corrected the
6332 seed calcualation for Win32 systems, and added -lsdbm support.
6335 *) Configured mod_auth_dbm to compile with sdbmlib under Win32.
6338 *) Avoid a segfault when parsing .htaccess files. An
6339 uninitialized tree pointer was passed to ap_build_config().
6342 *) Change the way that inet_addr & inet_network are checked for
6343 in APR's configure process to allow BeOS BONE to correctly
6344 find them. With this change BeOS BONE now builds from source
6345 with no problems. [David Reid]
6347 *) Fix a bug in apr_create_process() for Unix. The NULL signifying
6348 the end of the parameters to execve() was stored in the wrong
6349 location, overlaying the storage beyond the newargs[] array and
6350 also passing uninitialized storage to execve(), which would
6351 sometimes fail with EFAULT. [Jeff Trawick]
6353 *) Fix a bug parsing configuration file containers. With a sequence
6354 like this in the config file
6356 <IfModule mod_kilroy.c>
6359 <IfModule mod_lovejoy.c>
6364 the second container would be terminated at the blank line due to
6365 sediment in the buffer from reading the prior </IfModule> and an
6366 error message would be generated for the real </IfModule> for the
6367 second container. Also due to this problem, any two characters
6368 could be used for "</" in the close of a container.
6371 *) ap_add_filter prototype changed to remove the ctx pointer. The
6372 pointer still remains in the filter structure, but it can not be
6373 a part of the ap_add_filter prototype. The reason is that when
6374 the core uses AddFilter to add a filter to the stack it doesn't
6375 know how to allocate the ctx pointer, or even how much memory should
6376 be allocated. The filters will have to be responsible for allocating
6377 the ctx memory when they need it.
6380 *) Add an AddFilter directive. This directive takes a list of filters
6381 that should be activated for the requested resource.
6384 *) apr_snprintf(): Get quad format strings working on OS/390 (and perhaps
6385 some other platforms). [Jeff Trawick]
6387 *) Modify mod_include to be a filter. Currently, it has only been tested
6388 on actual files, but it should work for CGI scripts too.
6391 *) apr_putc(), apr_puts() for Unix: handle buffered files and interrupted
6392 writes. apr_flush() for Unix: handle interrupted writes.
6395 *) NameVirtualHost can now take "*" as an argument instead of
6396 an IP address. This allows you to create a purely name-based
6397 virtual hosting server that does not have any IP addresses in
6398 the configuration file and which ignores the local address
6399 of any connections. PR #5595, PR #4455 [Tony Finch]
6401 *) Fix some compile warnings in mod_mmap_static.c
6402 [Mike Abbott <mja sgi.com>]
6404 *) Fix chunking problem with CGI scripts. The general problem was that
6405 the CGI modules were adding an EOS bucket and then the core added an
6406 EOS bucket. The chunking filter finalizes the chunked response when it
6407 encounters an EOS bucket. Because two EOS buckets were sent, we
6408 finalized the response twice. The fix is to make sure we only send one
6409 EOS, by utilizing a flag in the request_rec.
6412 *) apr_put_os_file() now sets up the unget byte appropriately on Unix
6413 and Win32. Previously, the first read from an apr_file_t set up via
6414 apr_put_os_file() would return a '\0'. [Jeff Trawick]
6416 *) Mod_cgid now creates a single element bucket brigade, with a pipe
6417 bucket, instead of using BUFF's and ap_r*.
6420 *) APRVARS.in no longer overwrites the EXTRA_LIBS variable.
6421 [Mike Abbott <mja sgi.com>]
6423 *) Remove ap_bopenf from buff code. This required modifying the file_cache
6424 code to use APR file's directly instead of going through BUFFs.
6427 *) Fix compile break on some platforms for mod_mime_magic.c
6428 [John K. Sterling <sterling covalent.net>]
6430 *) Fix merging of AddDefaultCharset directive.
6431 PR #5872 (1.3) [Jun Kuriyama <kuriyama imgsrc.co.jp>]
6433 *) Minor revamp of the rlimit sections of code. We now test
6434 explicitly for setrlimit and getrlimit. Also, unixd_set_rlimit()
6435 is now "available" even if the platform doesn't support
6436 the rlimit family (it's just a noop though). [Jim Jagielski]
6438 *) Migrate the pre-selection of which MPM to use for specific
6439 platforms to hints.m4, which contains (or should contain)
6440 all platform specific "hints". [Jim Jagielski]
6442 *) Remove IOLs from Apache. With filtering, IOLs are no longer necessary
6445 *) Add tables with non-string/binary values to APR.
6448 *) Fix some bad calls to ap_log_rerror() in mod_rewrite.
6451 *) Update PCRE to version 3.2. [Ryan Bloom]
6453 *) Change the way buckets' destroy functions are called so that
6454 they can be more directly used when changing the type of a
6455 bucket in place. [Tony Finch]
6457 *) Add generic support for reference-counting the resources used by
6458 buckets, and alter the HEAP and MMAP buckets to use it. Change
6459 the way buckets are initialised to support changing the type of
6460 buckets in place, and use it when setting aside TRANSIENT buckets.
6461 Change the implementation of TRANSIENT buckets so that it can be
6462 mostly shared with IMMORTAL buckets, which are now implemented.
6465 Changes with Apache 2.0a6
6467 *) Add support to Apache and APR for dsos on OS/390. [Greg Ames]
6469 *) Add a chunking filter to Apache. This brings us one step closer
6470 to removing BUFF. [Ryan Bloom]
6472 *) ap_add_filter now adds filters in a LIFO fashion. The first filter
6473 added to the stack is the last filter to be called. [Ryan Bloom]
6475 *) Apache 2.0 has been completely documented using Scandoc. The
6476 docs can be generated by running 'make docs'. [Ryan Bloom]
6478 *) Add filtered I/O to Apache. This is based on bucket brigades,
6479 Currently the buckets still use BUFF under the covers, but that
6480 should change quickly. The only currently written filter is the
6481 core filter which just calls ap_bwrite. [The Apache Group]
6483 *) APR locks on Unix: Let APR_LOCKALL locks work when APR isn't
6484 built with thread support. [Jeff Trawick]
6486 *) Abort configuration if --with-layout was specified and there's
6487 no layout definition file. [Ken Coar]
6489 *) Add support for '--with-port=n' option to configure. [Ken Coar]
6491 *) Add support for extension methods for the Allow response header
6492 field, and an API routine for accessing r->allowed and the
6493 list of extension methods in a unified manner. [Ken Coar]
6495 *) mod_cern_meta: fix broken file reading loop in scan_meta_file().
6496 [Rob Simonson <simo us.ibm.com>]
6498 *) Get xlate builds working again. The apr renaming in 2.0a5 broke
6499 APACHE_XLATE builds. [Jeff Trawick]
6501 *) A configuration file parsing problem was fixed. When the
6502 configuration file started with an IfModule/IfDefine container,
6503 only the last statement in the container would be retained.
6506 Changes with Apache 2.0a5
6508 *) Perchild is serving pages after passing them to different child
6509 processes. There are still a lot of bugs, but this does work. I
6510 have made requests against the same installation of Apache, and had
6511 different servers use different user IDs to serve the responses.
6512 This change moves to using socketpair instead of an AF_UNIX socket.
6515 *) Perchild MPM still doesn't work perfectly, but it is serving pages.
6516 It can't seem to pass between child processes yet, but I think we
6517 are closer now than before. This moves us back to using Unix
6518 Domain Sockets. [Ryan Bloom]
6520 *) libapr functions and types renamed with apr_ prefix.
6521 #include "apr_compat.h" for 1.3.x backwards compat
6524 *) Fix problems with APR sockaddr handling on Win32. It didn't always
6525 return the right information on the local socket address.
6526 [Gregory Nicholls <gnicholls level8.com>]
6528 *) ap_recv() on Win32: Set bytes-read to 0 on error.
6529 [Gregory Nicholls <gnicholls level8.com>]
6531 *) Add an option to not detach from the controlling terminal without
6532 going into single process mode. This allows for much easier
6533 debugging of the process startup code. [Ryan Bloom]
6535 *) ab: don't use perror() to report the failure of an APR function.
6538 *) Make dexter, mpmt_pthread, and perchild MPMs not destroy the
6539 scoreboard on graceful restarts.
6542 *) Fix segfault/SIGSEGV when running gzip from mod_mime_magic.c.
6543 An invalid ap_proc_t was passed to ap_create_process().
6546 *) Allow modules to register filters. Those filters are still
6547 never called, but this is a step in the right direction.
6548 [Ryan Bloom and Greg Stein]
6550 *) Register the mod_cgid daemon process for cleanup so that it is
6551 killed at termination if it does not die when the parent gets
6552 SIGTERM. This change is to fix occasional problems where the
6553 process stays around. Bugs in similar logic in mod_rewrite and
6554 mod_include were also fixed. [Jeff Trawick]
6556 *) Fix a bug in the time handling. Basically, we were imploding a time
6557 in ap_parseHTTPdate, but it had bogus data in the exploded time format.
6558 Namely, tm_usec and tm_gmtoff were not filled out. ap_implode_time
6559 uses those two fields to adjust the time value. Because of the HTTP
6560 spec, both of those values can be zero'ed out safely. This fixes
6561 the bug correctly. [Ryan Bloom]
6563 *) Fix a couple of place in the Windows code where the wrong error
6564 code was being returned. [Gregory Nicholls <gnicholls level8.com>]
6566 *) Fix POOL_DEBUG (at least for prefork mpm). [Dean Gaudet]
6568 *) Added the APR_EOL_STR macro for platform dependent differences in
6569 logfiles and other raw text (such as all APR files). Fixes logfiles
6570 not terminated with cr/lf sequences in Win32. [William Rowe]
6572 *) Move all strings functions in APR to src/lib/apr/strings and create
6573 apr_strings.h for the prototypes. [Ryan Bloom]
6575 *) APR lock fixes: when using SysV sems, flock(), or fcntl(), be sure
6576 to repeat the syscall until we stop getting EINTR. I noticed a
6577 related problem at termination (SIGTERM) on FreeBSD when using
6578 fcntl(). Apache 1.3 had these new loops too. Also, make the flock()
6579 implementation work properly with child init. Previously, ap_lock()
6580 was essentially a no-op because all children were using different
6581 locks and thus nobody ever blocked. [Jeff Trawick]
6583 *) The htdocs/ tree has been moved out of the CVS source tree into
6584 a separate area for easier development. This has NO EFFECT on
6585 end-users or Apache installations. [Ken Coar]
6587 *) Integrate the mod_dav module for WebDAV protocol handling. This
6588 adds the dav and dav_fs modules, the SDBM library, and additional
6589 XML handling utilities. [Greg Stein]
6591 *) Clean out obsolete names (from httpd.h) for the HTTP Status Codes
6594 *) Update the lib/expat-lite/ library (bring forward changes from
6595 the Apache 1.3 repository). [Greg Stein]
6597 *) If sizeof(long long) == sizeof(long), then prefer long in APR
6598 configure.in. [Dave Hill <ddhill zk3.dec.com>]
6600 *) Add ap_sendfile for Tru64 Unix. Also, add an error message for
6601 machines where sendfile is detected, but nobody has written ap_sendfile.
6602 [Dave Hill <ddhill zk3.dec.com>]
6604 *) Compile fixes in mod_mmap_static. [Victor J. Orlikowski]
6606 *) ab would start up more connections than needed, then quit when the
6607 desired number were finished. Also fixed a logic error involving
6608 ab keepalives. [Victor J. Orlikowski]
6610 *) WinNT: Implement non-blocking pipes with timeouts to communicate
6611 with CGIs. Apache 2.0a4 had non-blocking pipes but without
6612 timeouts (i.e, if a timeout was specified, the pipe reverted to
6613 a full blocking pipe). Now the behaviour is more in line with
6614 Unix non-blocking pipes.
6617 *) WinNT: Implement accept socket reuse. Using mod_file_cache to
6618 cache open file handles along with accept socket reuse enables
6619 Apache 2.0 to serve non-keepalive requests for static files at
6620 3x the rate of Apache 1.3.(e.g, Apache 1.3 will serve 400 rps
6621 and Apache 2.0 will serve almost 1200 rps on my system).
6624 *) Merge mod_mmap_static function into mod_file_cache. mod_file_cache
6625 supports two config directives, mmapfile (same behavious as
6626 mod_mmap_static) and cachefile. Use the cachefile directive
6627 to cache open file handles. This directive only works on systems
6628 that have implemented the ap_sendfile API. cachefile works today
6629 on Windows NT, but has not been tested on any flavors of Unix.
6632 *) Cleanup the configuration. With the last few changes the
6633 configuration process automatically:
6634 inherits information about how to build from APR. Allowing
6635 APR to inform Apache that it should or should not use -ldl
6637 Detects which mod_cgi should be used mod_cgi or mod_cgid,
6638 based on the threading model
6640 Apache calls APR's configure process before finishing it's
6641 configuration processing, allowing for more information flow
6646 *) Change Unix and Win32 ap_setsockopt() so that APR_SO_NONBLOCK
6647 with non-zero argument makes the socket non-blocking. BeOS and
6648 OS/2 already worked this way. [Jeff Trawick]
6650 *) ap_close() now calls ap_flush() for buffered files, so write
6651 operations work a whole lot better on buffered files.
6654 *) Fix error messages issued from MPMs which explain where to change
6655 compiled-in limits (e.g., ThreadsPerChild, MaxClients, StartTreads).
6658 *) ap_create_pipe() now leaves pipes in blocking state. (This helps
6659 reduce the number of syscalls on Unix.) ap_set_pipe_timeout() is
6660 now the way that the blocking state of a pipe is manipulated.
6661 ap_block_pipe() is gone. [Jeff Trawick]
6663 *) Correct the problem where the only local host name that the IP stack
6664 can discover are 'undotted' private names. If no fully qualified
6665 domain name can be identified, the default ServerName will be set to
6666 the machine's IP address string. A warning is always provided if the
6667 ServerName not specified, but assumed. Solves PR6215 [William Rowe]
6669 *) Repair problems with config file processing which caused segfault
6670 at init when virtual hosts were defined and which caused ServerName to
6671 be ignored when there was no valid DNS setup. [Jeff Trawick]
6673 *) Removed pointless ap_is_aborted macro function. [Roy Fielding]
6675 *) Add ap_sendfile implementation for AIX
6676 [Victor J. Orlikowski]
6678 *) Repair C++ compatibility in ap_config.h, apr_file_io.h,
6679 apr_network_io.h, and apr_thread_proc.h.
6680 [Tyler J. Brooks <tylerjbrooks home.com>, Jeff Trawick]
6682 *) Bring the allocation and pool debugging code back into a working
6683 state. This will need to be tested as so far it's only been used on
6686 *) Change configuration command setup to be properly typesafe when in
6687 maintainer mode. Note that this requires a compiler that can initialise
6688 unions. [Ben Laurie]
6690 *) Turn on buffering for config file reads. Part of this was to
6691 repair buffered I/O support in Unix and implement buffered
6692 ap_fgets() for all platforms. [Brian Havard, Jeff Trawick]
6694 *) Win32: Fix problem where UTC offset was not being set correctly
6695 in the access log. Problem reported on news group by Jerry Baker.
6698 *) Fix segfault when reporting this type of syntax error:
6699 "</container> without matching <container> section", where
6700 container is VirtualHost or Directory or whatever.
6703 *) SECURITY: CAN-2000-1204 (cve.mitre.org)
6704 Prevent the source code for CGIs from being revealed when
6705 using mod_vhost_alias and the CGI directory is under the document root
6706 and a user makes a request like http://www.example.com//cgi-bin/cgi
6707 as reported in <news:960999105.344321 ernani.logica.co.uk>
6710 *) Add support for the new Beos NetwOrking Environment (BONE)
6713 *) xlate: ap_xlate_conv_buffer() now tells the caller when the
6714 final input char is incomplete; ap_bwrite_xlate() now handles
6715 incomplete final input chars. [Jeff Trawick]
6717 *) Yet another update to saferead/halfduplex stuff -- need to ensure
6718 that a bhalfduplex call occurs before logging or else DNS and
6719 such can delay the last packet of the response. [Dean Gaudet]
6721 *) Some syscall reduction in APR on unix -- don't seek when setting
6722 up an mmap; and don't fcntl() more than once per socket.
6725 *) When mod_cgid is started as root, the cgi daemon now switches
6726 to the configured User/Group (like other httpd processes)
6727 instead of continuing as root. [Jeff Trawick]
6729 *) The prefork MPM now uses an APR lock for the accept() mutex.
6730 It has not been getting a lock at all recently. httpd -V now
6731 displays APR's selection of the lock mechanism instead of the
6732 symbols previously respected by prefork. [Jeff Trawick]
6734 *) Change the mmap() feature test to check only for existence.
6735 The previous check required features not used by Apache.
6738 *) Fix a couple of bugs in mod_cgid: The cgi arguments were
6739 sometimes mangled. The len parm to accept() was not
6740 initialized, leading sometimes to an endless loop of failed
6741 accept() calls on OS/390 and anywhere else that failed the call
6742 if the len was negative. Use <sys/un.h> for struct sockaddr_un
6743 instead of declaring it ourselves to fix a compilation problem
6744 on Solaris. [Jeff Trawick]
6746 *) Add Resource limiting code back into Apache 2.0. [Ryan Bloom]
6748 *) Fix zombie process problem with mod_cgi. [Jeff Trawick]
6750 *) Port mod_mmap_static to 2.0. Make it go faster. [Greg Ames]
6752 *) Fix storage overlay when loading dsos. Symptom: Apache dies at
6753 initialization if ALLOC_DEBUG is defined; no known symptom
6754 otherwise. [Jeff Trawick]
6756 *) Fix typo in configure script when checking for mod_so. bash
6757 doesn't seem to have a problem but /bin/sh on Solaris does.
6758 Symptom: "./configure: test: unknown operator =="
6761 *) Rebind the Win32 NT and 9x services control into the MPM.
6762 All console, WinNT SCM and Win9x pseudo-service control code is
6763 now wrapped within the WinNT MPM.
6766 *) Make a copy of getenv("PATH") before storing for later use. Some
6767 getenv() implementations use the same storage for successive calls.
6768 CGIs on OS/390 had a bad PATH due to this. [Jeff Trawick]
6770 *) Server Tokens work in 2.0 again. This also propogates the change
6771 to allow just the product name in the server string using
6775 Changes with Apache 2.0a4
6777 *) EBCDIC: Rearrange calls to ap_checkconv() so that most handlers
6778 won't need to call it. [Greg Ames, Jeff Trawick]
6780 *) Move pre_config hook call to between configuration read and config
6781 tree walk. This allows all modules to implement pre_config hooks
6782 and know that they will be called at an appropriate time.
6785 *) mod_cgi, mod_cgid: Make ScriptLog directive work again.
6788 *) Add pre-config hooks back to all modules.
6791 *) Fix a SIGSEGV in ap_md5digest(), which is used when you have
6792 ContentDigest enabled and we can't/don't mmap the file.
6795 *) We now report the correct line number for syntax errors in config
6796 files. [Ryan Bloom, Greg Stein, Jeff Trawick]
6798 *) Brought mod_auth_digest up to synch with 1.3, fixed ap_time_t-
6799 related bugs, and changed shmem/locking to use apr API. Shared-mem
6800 is currently disabled, however, because of problems with graceful
6801 restarts. [Ronald Tschalär]
6803 *) Fix corruption of IFS variable in --with-module= handling.
6804 Depending on the user's shell or customization thereof, there
6805 would be errors generating ap_config_auto.h later in the configure
6806 procedure. [Jeff Trawick]
6808 *) mod_cgi: Restore logging of stderr from child process when ScriptLog
6809 isn't used (as in 1.3), except that on Unix it is now logged via
6810 ap_log_rerror() instead of by the child having STDERR_FILENO refer
6811 to the error log. [Greg Ames, Jeff Trawick]
6813 *) Add '-D' argument processing for run time configuration defines.
6816 *) Organize http_main.c as independent code, such that no code or
6817 global data is exported from it. WIN32 will dynamically link it
6818 to the server core, so this will prevent mutual dependency.
6821 *) Add separate dynamic linkage tags APR_EXPORT(), APR_EXPORT_NONSTD()
6822 and APR_VAR_EXPORT to correctly resolve apr functions and globals.
6825 *) Add Win9x service execution and Ctrl+C/Ctrl+Break/Shutdown handlers.
6826 [William Rowe, Jan Just Keijser <KEIJSERJJ logica.com>]
6828 *) Add mod_charset_lite for configuring character set translation.
6831 *) Add '-n' option to htpasswd to make it print its user:pw record
6832 on stdout rather than having to frob a text file. [Ken Coar]
6834 *) Fix saferead. Basically, we flush the output buffer if a read on the
6838 *) APR: Add ap_xlate_get_sb() so that an app can find out whether or not
6839 a conversion is single-byte only. [Jeff Trawick]
6841 *) BEOS: ap_shutdown should return APR_SUCCESS or errno. Note that
6842 the BeOS 5.0 documentation says that shutdown doesn't work yet.
6845 *) Fix some minor errors where pid was being manipulated as an int
6846 instead of the portable pid_t. [Roy Fielding]
6848 *) Fix some error log prints that were printing the pointer to a
6849 structure rather than the pid within the structure.
6850 [Jeff Trawick, Roy Fielding]
6852 *) ab: Fix a command-line processing bug; track bad headers in
6853 err_response; support reading headers up to 2K.
6854 [Ask Bjoern Hansen <ask valueclick.com>]
6856 *) Fix ap_resolve_env() so that it handles new function added in a prior
6857 alpha (see "Added the capability to do ${ENVVAR} constructs in the
6858 config file.") as well as the constructs used by mod_rewrite.
6859 [Paul Reder <rederpj raleigh.ibm.com>]
6861 *) Apache 2.0 builds and runs on OS/390. [Jeff Trawick, Greg Ames]
6863 *) Change the EBCDIC support in functions for MD5, SHA1, and base 64 to use
6864 APR to perform translation, instead of accessing the hard-coded tables
6865 in 1.3's ebcdic.c. [Jeff Trawick]
6867 *) Fix some bugs (mostly lost 1.3 code) in ab's command-line processing.
6870 *) Add the ability to hook into the config file reading phase. Basically
6871 if a directive is specified EXEC_ON_READ, then when that directive is
6872 read from the config file, the assocaited function is executed. This
6873 should only be used for those directives that must muck with HOW the
6874 server INTERPRETS the config. This should not be used for directives
6875 that re-order or replace items in the config tree. Those changes should
6876 be made in the pre-config step.
6879 *) Add mod_example to the build system.
6882 *) APR: Add ap_xlate_conv_byte() to convert one char between single-
6883 byte character sets. [Jeff Trawick]
6885 *) Pick up various EBCDIC fixes from 1.3 (from Martin
6886 Kraemer and Oliver Reh originally according to the change log).
6889 *) Fix a couple of problems in RFC1413 support (controlled by the
6890 IdentityCheck directive). Apache did not build the request string
6891 properly and more importantly Apache would loop forever if the
6892 would-be ident server dropped the connection before sending a
6893 properly terminated response. [Jeff Trawick]
6895 *) apxs works in 2.0.
6898 *) Reliable piped logs work in 2.0.
6901 *) Introduce a hash table implementation into APR to be used for
6902 replacing tables and other random data structures in Apache.
6905 *) Add some more error reporting to htpasswd in the case of problems
6906 generating or accessing the temporary file. Also, pass in a
6907 buffer if the implementation knows how to use it (i.e., if L_tmpnam
6908 is defined). [Ken Coar]
6910 *) Configure creates config.nice now containing your configure
6911 options. Syntax: ./config.nice [--more-options]
6914 *) Fix various return code problems in APR on Win32. For most of
6915 these, APR was returning APR_EEXIST instead of GetLastError()/
6916 WSAGetLastError(). [Jeff Trawick]
6918 *) Make piped logs work again in version 2.0
6921 *) Add VPATH support to UNIX build system of Apache and APR.
6924 *) Fix ap_tokenize_to_argv to respect the const arguments that are
6928 *) Fix mm's memcpy/memset macros, pointer arithmetic was broken.
6929 Patch submitted to author.
6932 *) Fix mm configuration on Solaris 8 x86 and OS/390. Don't require
6933 /sbin in PATH on FreeBSD (all submitted to rse previously)
6936 *) Fix building Pthread-based MPMs on OpenBSD
6937 [Sascha Schumann] PR#26
6939 *) Fix ap_readdir() problem on systems where d_name[] field in
6940 struct dirent is declared with only one byte. (This problem only
6941 affected multithreaded builds.) This caused a segfault during
6942 pool cleanup with mod_autoindex on Solaris (Solaris 8 x86, at
6943 least). [Jeff Trawick]
6945 *) Fix some make-portability problems on at least Tru64, Irix
6947 [Sascha Schumann] PR#18, PR#39
6949 *) Add ap_sigwait() to support old-style sigwait() on systems
6950 like OS/390 and UnixWare.
6953 *) Add POSIX-thread flags for more platforms.
6956 *) Fix some minor bugs in ap_strerror(). Teach ap_strerror()
6957 (on Unix, at least) to handle resolver errors. Fix a bug in
6958 the definition of APR_ENOMEM so that ap_strerror() can spit
6959 out the correct error message for it.
6962 Changes with Apache 2.0a3
6964 *) mod_so reports ap_os_dso_error() if ap_dso_load() fails
6967 *) API: *HOOK* macros now have an AP_ prefix
6970 *) Win32: Eliminate redundant calls to initialize winsock.
6971 [Tim Costello <timcostello ozemail.com.au>]
6973 *) Fix bugs initializing ungetchar for pipes.
6974 [Chia-liang Kao <clkao CirX.ORG>]
6976 *) The ab program in the src/support directory is now portable using
6980 *) Support directory is being compiled when the server is built
6983 *) The configure option --with-program-name has been added to allow
6984 developers to rename the executable at configure time. This also
6985 changes the name of the config files to match the executable's name.
6988 *) mod_autoindex: Add `IndexOptions +VersionSort', to nicely sort filenames
6989 containing version numbers. [Martin Pool]
6991 *) ap_open(..,APR_OS_DEFAULT,..) uses perms 0666 instead of 0777 on
6992 Unix; access_log and error_log now created with these perms; non-
6993 Unix is unaffected [Jeff Trawick]
6995 *) Finished move of ap_md5 routines to apr_md5. Removed ap_md5.h.
6996 Replaced more magic numbers with MD5_DIGESTSIZE.
6997 [William Rowe, Roy Fielding]
6999 *) Win32: Get mod_auth_digest compiling and added to the Windows
7000 build environment. Not tested and I'd be suprised if it
7001 actually works. [Bill Stoddard]
7003 *) Revamp the Win32 make environment. Makefiles have been removed and
7004 Apache.dsw created to bring together all the pieces. Create new file
7005 os/win32/BaseAddr.ref to define module base addresses (to prevent
7006 dll relocation at start-up).
7007 [William Rowe, Greg Marr, Tim Costello, Bill Stoddard]
7009 *) [EBCDIC] Port Paul Gilmartin's CRLF patch from 1.3. This replaces most
7010 of the \015, \012, and \015\012 constants with macros.
7013 *) Add ap_xlate_open() et al for translation of text between different
7014 character sets. The initial implementation requires iconv().
7017 *) More FAQs and answers from comp.infosystems.www.servers.unix.
7018 [Joshua Slive <slive finance.commerce.ubc.ca>]
7020 *) CGI output is being timed out now.
7023 *) Fix the problem with dieing quietly. dupfile now takes a pool which
7024 is used by the new apr file. There is no reason to create a new file
7025 with the same lifetime as the original file.
7028 *) Win32: Attempt to eliminate dll relocation at start-up by specifying
7029 module base addresses. This will help shooting seg faults
7030 in the field. [William Rowe <wrowe lnd.com>]
7032 *) Update Apache on Windows documentation. Add new document
7033 describing how to compile Apache on Windows.
7034 [William Rowe <wrowe lnd.com>]
7036 *) ap_set_pipe_timeout(), ap_poll(), and APR_SO_TIMEOUT now take
7037 microseconds instead of seconds. Some storage leaks and other
7038 minor bugs in related code were fixed. [Jeff Trawick]
7040 *) Win32: First cut at getting mod_isapi working under 2.0
7041 [William Rowe <wrowe lnd.com>]
7043 *) First stab at getting mod_auth_digest working under 2.0
7044 quick change summary:
7045 - moved the random byte generation (ap_generate_random_bytes) into APR
7046 - now uses ap_time_t
7047 - compiles and runs on linux
7049 [Brian Martin <bmartin penguincomputing.com>]
7051 *) Win32: Move the space stripping of physical service names
7052 fix up from Apache 1.3. #include'ing "ap_mpm.h" fixes up an
7053 unresolved symbol. Add dependency checking to the
7054 CreateService call to ensure TCPIP and AFP (winsock) is started
7056 [William Rowe <wrowe lnd.com>]
7058 *) Win32: Add code to perform latebinding on functions that may
7059 not exist on all levels of Windows where Apache runs. This
7060 is needed to allow Apache to start-up on Win95/98. All calls
7061 to non portable functions should be protected with
7062 ap_oslevel checks to prevent runtime segfaults.
7063 [William Rowe <wrowe lnd.com>]
7065 *) Fix fallback default values for SHM_R and SHM_W [Martin Kraemer]
7067 *) Get lingering_close() working again. [Dean Gaudet, Jeff Trawick]
7069 *) Win32: Get non-blocking CGI pipe reads working under Windows NT.
7070 This addresses PR 1623. Still need to address timing out runaway
7071 CGI scripts. [Bill Stoddard]
7073 *) Win32: Make ap_stat Windows 95/98 friendly
7074 [William Rowe <wrowe lnd.com>]
7076 *) Win32: Fix a bug in ap_get_oslevel which causes GetVersionEx() to
7077 always fail. Need to initialise the dwOSVersionInfoSize member of the
7078 OSVERSIONINFO struct before calling GetVersionEx, so GetVersionEx
7081 The patch also enhances ap_get_oslevel (and the associated enum) to
7082 handle selected service packs for NT4, and adds recognition for
7083 Windows 2000. This is useful, eg. if we can recognise NT4 SP2 then
7084 we can use ReadFileScatter and WriteFileGather in readwrite.c.
7085 [Tim Costello <Tim.Costello BTFinancialgroup.com>]
7087 *) Get mod_rewrite building and running, and mod_status building for Win NT
7088 [Allan Edwards <ake raleigh.ibm.com>]
7090 *) Patch to port mod_auth_db to the 2.0 api and also to support
7091 Berlekey DB 3.0. It works for me with both Berkeley DB 3.0.55 and
7092 2.7.7. It should work with version 1 as well but I haven't tested it.
7093 [Brian Martin <bmartin penguincomputing.com>]
7095 *) Get APR DSO code working under Windows. Includes cross platform
7097 [<Tim.Costello BTFinancialgroup.com>]
7099 *) Fix some of the Windows APR time functions.
7102 *) FAQ changes related to tidying up historical documents on the web site.
7103 [Joshua Slive <slive finance.commerce.ubc.ca>]
7105 *) Move Windows DSO code into APR.
7108 *) Eliminate apr_win.h and apr_winconfig.h (and the ugly #ifdefs they cause).
7109 Now, apr.h and apr_config.h are generated from apr.hw and apr_config.hw
7110 at build time. At this point, the server will not compile on Windows because
7111 of the recent DSO commits. Fixing those next.
7112 [Bill Rowe & Bill Stoddard]
7114 *) Added error checking for file I/O APR routines.
7115 [Jon Travis <jtravis covalent.net>]
7117 *) APR: Don't use the values of resolver error codes for the
7118 corresponding APR error codes. On Unix and Win32, return the
7119 proper APR error code after a resolver error. [Jeff Trawick]
7121 Changes with Apache 2.0a2
7123 *) Renamed the executable back to httpd on all platforms other
7127 *) Allow BeOS to survive restarts, log properly and a few
7128 small things it had problems with due to the way it setup
7129 users and groups. [David Reid]
7131 *) Get mod_rewrite working with APR locks
7132 [Paul Reder <rederpj raleigh.ibm.com>]
7134 *) Actually remove the sempahore when the lock cleanup routine
7135 is called on BeOS. [David Reid]
7137 *) Clear hook registrations between reads of the config file.
7138 When DSOs are unloaded and re-loaded the old hook pointers may
7139 no longer be valid. This fix eliminates potential segfaults.
7140 [Allan Edwards <ake raleigh.ibm.com>]
7142 *) Fix a problem with Sigfunc not being defined or bypassed
7143 if sigaction() wasn't found. [Jim Jagielski]
7145 *) Fix the locking mechanism on BSD variants. They now use fcntl
7146 locks. This allows the server to start and serve pages.
7149 *) First cut at getting the Win32 installer to work
7150 [William Rowe <wrowe lnd.com>]
7152 *) Get htpasswd compiling under Windows
7153 [William Rowe <wrowe lnd.com>]
7155 *) Change the log message for a bind() failure to show the
7156 interface and port number. [Jeff Trawick]
7158 *) Import the documentation from 1.3.12 and bring parts of it
7159 up-to-date with respect to the changes that have occurred
7163 *) BeOS MPM updated. CGI bug on BeOS fixed. IP addresses
7164 now logged correctly on BeOS.
7167 *) Create one makefile for all Win32 distributions (NT/2000/95/98).
7168 Makefile.win includes the same user interface as the old
7170 [William Rowe <wrowe lnd.com>, Jeff Trawick <trawick us.ibm.com>]
7172 *) Win32 exec now uses COMSPEC environment string for command
7173 shell path resolution.
7174 [William Rowe <wrowe lnd.com>] PR#3715
7176 *) Win32: ap_connect() was not returning correct error condition
7178 [Allen Prescott <allen clanprescott.com>]
7180 *) Win32: ap_open() was broken on Win9x because an NT-specific
7181 flag was passed to CreateFile. ap_puts() added an unnecessary
7183 [Jeff Trawick <trawick us.ibm.com>]
7185 *) Put in Korean and Norwegian index.html pages (2.0 and 1.3)
7186 which where donated by Lee Kuk Hyun and Lorant Czaran. 'Fixed'
7187 confusing ee/et name and made all extensions language/dialect
7188 rather than country reflecting. Changed example files to
7189 explicit reflect the ISO charset and added a few common
7190 ones to the example config [dirkx]
7192 *) Extend external module capability. To use this, you call
7193 configure with --with-module=path/to/mod1,path/to/mod2,etc.
7196 *) Backported the various "default charset" fixes from 1.3.12,
7197 including the AddDefaultCharset directive. [Jim Jagielski]
7199 *) Added the capability to do ${ENVVAR} constructs in the
7200 config file. E.g. 'ServerAdmin ${POSTMASTER}'. As commited
7201 it does this on a line by line basis; i.e. if the envvar
7202 expands to something with spaces you have to protect it
7203 by adding quotes around it (Unless of course you expect it
7204 to contains more than one argument. Alternatively you
7205 can compile it on a per token basis; which is what people
7206 usually expect by setting RESOLVE_ENV_PER_TOKEN. But this
7207 hampers fancier hacks.
7208 [Dirk-Willem van Gulik]
7210 *) Changed the 'ErrorDocument' syntax in that it NO longer
7211 supports the asymetric
7213 ErrorDocument 301 "Some message
7215 Note the opening " quote, without a closing quote. It now
7216 has either the following syntaxes
7218 ErrorDocument XXX /local/uri
7219 ErrorDocument XXX http://valid/url
7220 ErrorDocument XXX "Some Message"
7222 The recognition heuristic is: if it has a space it
7223 is a message. If it has no spaces and starts with a /
7224 or is a valid URL then treat it that way. Otherwise it
7225 is assumed to be a message.
7227 This breaks backward compatibility but makes live a hell
7228 of a lot easier for GUI's and config file parsers.
7229 [Dirk-Willem van Gulik]
7231 *) Changed 'CacheNegotiatedDocs' from its present/not-present
7232 syntax into a 'on' or 'off' syntax. As it currently is the
7233 only non nesting token which uses NO_ARGS and thus is an
7234 absolute pain for any config interface automation. This
7235 breaks backward compatibility. [Dirk-Willem van Gulik]
7237 *) Add ability to add external modules to the build process. This is
7238 done with --with-module=/path/to/module. Modules can only be added
7239 as static modules at this point.
7242 Changes with Apache 2.0a1
7244 *) Fix FreeBSD 3.3 core dump.
7245 Basically, ap_initialize() needs to get called before
7246 create_process(), since create_process() passes op_on structure
7247 to semop() to get a lock, but op_on isn't initialized until
7248 ap_initialize() calls setup_lock(). Here is a slight
7249 rearrangement to main() which calls ap_initialize() earlier...
7250 [Jeff Trawick <trawick us.ibm.com>]
7252 *) Enable Apache to use sendfile/TransmitFile API
7253 [Bill Stoddard, David Reid, Paul Reder]
7255 *) Re-Implement Win32 APR network I/O APIs and most of the file I/O
7259 *) Make file I/O and network I/O writev/sendv APIs consistent.
7260 Eliminate use of ap_iovec_t and use Posix struct iovec.
7261 Use seperate variable on ap_writev to set the number of iovecs
7262 passed in and number of bytes written.
7265 *) Adapt file iol to use APR functions. Replaced ap_open_file()
7266 with ap_create_file_iol(). ap_create_file_iol() requires that
7267 the file be opened prior to the call using ap_open().
7270 *) Port mod_include and mod_cgi to 2.0
7271 [Paul Reder, Bill Stoddard]
7273 *) ap_send{,v}, ap_recv, ap_sendfile API clarification --
7274 bytes_read/bytes_written is always valid (never -1). Plus
7275 some fixes to buff.c to correct problems introduced by the
7276 errno => ap_status_t changes a while back. Plus a fix to
7277 chunked encoding introduced right at the beginning of 2.0.
7280 *) Revamped UNIX build system to use autoconf and libtool.
7281 [Manoj Kasichainula, Sascha Schumann]
7283 *) port mod_rewrite to 2.0. [Paul J. Reder <rederpj raleigh.ibm.com>]
7285 *) SECURITY: More rigorous checking of Host: headers to fix security
7286 problems with mass name-based virtual hosting (whether using mod_rewrite
7287 or mod_vhost_alias).
7288 [Ben Hyde, Tony Finch]
7290 *) Add back support for UseCanonicalName in <Directory> containers.
7291 [Manoj Kasichainula]
7293 *) Added APLOG_STARTUP log type. This allows us to write an error
7294 message without any of the date and time information. As a part
7295 of this change, I also removed all of the calls to fprintf(stderr
7296 and replaced them with calls to ap_log_error using APLOG_STARTUP
7297 writing to stderr is no longer portable, because we don't direct
7298 stderr to the error log on all platforms.
7301 *) Convert error logging functions to take errno as an argument.
7302 This makes our error logs more portable, because some Windows API's
7303 don't set errno. This change allows us to still output a valid
7304 message on all of our platforms.
7307 *) mod_mime_magic runs in 2.0-dev now.
7308 [Paul Reder <rederpj raleigh.ibm.com>]
7310 *) sendfile has been added to APR.
7311 [John Zedlewski <zedlwski Princeton.EDU>]
7313 *) buff.c has been converted to no longer use errno.
7314 [Manoj Kasichainula]
7316 *) mod_speling runs in 2.0-dev now: a bug in readdir_r handling and
7317 interface adaption to APR functions did it. [Martin Kraemer]
7319 *) Support DSOs properly on 32-bit HP-UX 11.0
7320 [Dilip Khandekar <dilip cup.hp.com>]
7322 *) Updated MM in APR source tree from version 1.0.8 to 1.0.11
7323 [Ralf S. Engelschall]
7325 *) Cleaned APR build environment integration and bootstrap APR
7326 automatically for developers from src/Configure.
7327 [Ralf S. Engelschall]
7329 *) Fixed building of src/support/htpasswd.c
7330 [Ralf S. Engelschall]
7332 *) When generating the Location: header, mod_speling forgot
7333 to escape the spelling-fixed uri. (Forw-Port from 1.3)
7336 *) Moved mod_auth_digest.c from experimental to standard. [Roy Fielding]
7338 *) Change all pools to APR contexts. This is the first step to
7339 incorporating APR into Apache. [Ryan Bloom]
7341 *) Move "handler not found" warning message to below the check
7342 for a wildcard handler. [Dirk <dirkm teleport.com>, Roy Fielding]
7343 PR#2584, PR#2751, PR#3349, PR#3436, PR#3548, PR#4384, PR#4795, PR#4807
7345 *) Support line-continuation feature in config.option file and
7346 allow the loading of multiple option sections at once via
7347 ``--with-option=<section1>,<section2>,...''
7348 [Ralf S. Engelschall]
7350 *) Rebuilt CVS repository with Apache 1.3.9 as basis. [Roy Fielding]
7352 Changes with Apache MPM
7354 *) Use asynchronous AcceptEx() and a completion port to accept and
7355 dispatch connections to threads in Windows NT/2000.
7358 *) Implement WINNT Win32 MPM from original Win32 code in http_main.c
7361 *) Implement the APACI --with-option facility
7362 (per default used the config.option file).
7363 [Ralf S. Engelschall]
7365 *) MPM BEOS port. [David Reid <abb37 dial.pipex.com>]
7367 *) Start to implement module-defined hooks that are a) fast and b) typesafe.
7368 Replace pre_connection module call with a register_hook call and
7369 implement pre_connection as a hook. The intent is that these hooks will
7370 be extended to allow Apache to be multi-protocol, and also to allow the
7371 calling order to be specified on a per-hook/per-module basis.
7374 *) Implement mpm_* methods as "modules". Each method gets its own
7375 subdir in src/modules (eg: src/modules/prefork). Selection
7376 of method uses Rule MPM_METHOD. [Jim Jagielski]
7378 *) Port the hybrid server from the apache-apr repository as
7379 mpm_mpmt_pthread. [Manoj Kasichainula]
7381 *) os/unix/unixd.[ch]: detach, setuid, setgid, stuff which will be common
7382 amongst the unix MPMs.
7384 *) mpm_prefork: throw away all the alarm/timeout crud; and clean up the
7385 signal handling for the new world order. [Dean Gaudet]
7387 *) Crude ap_thread_mutex abstraction so that we get the pthread stuff out
7388 of alloc.c for now. [Dean Gaudet]
7390 *) Handle partial large writes correctly. [Ben Laurie]
7392 *) Eliminate conn_rec's pointer to server. All it knows is the base server
7393 based on IP/port. [Ben Laurie]
7395 *) Port a bunch of modules to the new module structure.
7396 ["Michael H. Voase" <mvoase midcoast.com.au>]
7398 *) I/O layering and BUFF revamp. See docs/buff.txt. [Dean Gaudet]
7400 *) Basic restructuring to introduce the MPM concept; includes various
7401 changes to the module API... better described by
7402 docs/initial_blurb.txt. [Dean Gaudet]
7404 Changes with Apache pthreads
7406 *) New buff option added: BO_TIMEOUT. It describes the timeout for
7407 buff operations (generally over a network).
7408 [Dean Gaudet, Ryan Bloom, Manoj Kasichainula]
7410 *) Created http_accept abstraction. Added 4 new functions (not exported):
7411 init_accept(), begin_accepting_requests(), get_request(),
7412 stop_accepting_requests() [Bill Stoddard]
7414 *) Fix to ap_rprintf call that allows mod_info to work properly.
7415 [James Morris <jmorris intercode.com.au>]
7417 *) user and ap_auth_type fields were moved from connection_rec to
7418 request_rec. [Ryan Bloom]
7420 *) Removed the ap_block_alarms and ap_unblock_alarm calls. These aren't
7421 needed in a threaded server.
7423 *) Initial pthread implementation from from Dean's apache-nspr code.
7424 [Bill Stoddard, Ryan Bloom]
7427 Changes with Apache 1.3.9
7429 *) Remove bogus error message when a redirect doesn't set Location.
7430 Instead, use an empty string to avoid coredump if the error message
7431 was supposed to include a location. [Roy Fielding]
7433 *) Don't allow configure to include mod_auth_digest unless it is
7434 explicitly requested, even if the user asked for all modules.
7437 *) Translate module names to dll names for OS/2 so that they are no more
7438 than 8 characters long and have an extension of "dll" instead of "so".
7441 *) Print out pointer to Rule DEV_RANDOM when truerand lib not found.
7442 Fix test-compile check to check for randbyte instead of trand32.
7443 Use ap_base64encode_binary/decode instead of copy in mod_auth_digest.c
7444 and tweak to make Amaya happier. [Ronald Tschalär]
7446 *) Ensure that the installed expat include files are world readable,
7447 just like the other header files. [Martin Kraemer]
7449 *) Fixed generated AddModule adjustments in APACI's `configure' script
7450 in order to allow (new) modules like mod_vhost_alias to be handled
7451 correctly (which was touched by the adjustments for mod_alias).
7452 [Ralf S. Engelschall]
7454 *) For binary builds, add -R flag to apachectl to work around the lack of
7455 an absolute path to the ./libexec directory where the libhttp.ep file
7456 is needed for SHARED_CORE architectures. [Randy Terbush]
7458 *) WIN32: Create the CGI script process as DETACHED. This may solve the
7459 problem observed by some Win95/98 users where they get CGI script
7460 output sent to the console. [Bill Stoddard]
7462 *) Fix (re)naming in the uuencode/decode section. The ap/ap_
7463 routines are now called ap_base64* and are 'plain' (i.e., no
7464 pool access or anything clever). Inside util.c the routines acting
7465 like pstrdup are called ap_pbase64encode() and ap_pbase64decode().
7466 The oddly named ap_uuencode(), ap_uudecode() are kept around for
7467 now but deprecated. [dirkx]
7469 *) Clean up the base64 and SHA1 additions and make sure they are
7470 represented in the ApacheCore.def, ApacheCoreOS2.def, and httpd.exp
7471 files. [Roy Fielding]
7473 *) WIN32: Migrate to InstallShield 5.5 and provide a bit more error
7474 checking. Allow compiling on VS 6.0. [Randy Terbush]
7476 *) Fixed assumption of absolute paths in binbuild.sh. [Tony Finch]
7478 *) Use TestCompile to search for the truerand library (rather than blindly
7479 assuming its existence). If it is not found, complain (but do not
7480 exit - yet). [Martin Kraemer]
7482 *) We forgot to add the new exported function names to
7483 src/support/httpd.exp. [Bill Stoddard, Randy Terbush]
7485 *) Add description of -T command-line option to usage().
7486 [Ralf S. Engelschall]
7488 *) For "some" platforms (notably, EBCDIC based ones), libos needs to be
7489 searched only AFTER libap has been searched, because libap needs
7490 some symbols from libos. [Martin Kraemer]
7492 *) Fix conflict with original mod_digest related to the symbol of the
7493 module dispatch list (which has to be unique for DSO and follow the
7494 usual conventions for the installation procedure).
7495 [Ralf S. Engelschall]
7497 *) Add a dbm-library check for the "usual places" (-ldbm, -lndbm, -ldb)
7498 for other platforms as well. [Martin Kraemer]
7500 *) Make ap_sha1.c compile for EBCDIC platforms: replace remaining LONG
7501 types by AP_LONG and replace reference to renamed variable 'ubuf'
7502 by 'buffer'. [Martin Kraemer]
7504 Changes with Apache 1.3.8 [not released]
7506 *) Flush the output buffer immediately after sending an error or redirect
7507 response, since the result may be needed by the client to abort a
7508 long data transfer or restart a series of pipelined requests.
7509 [Tom Vaughan <tvaughan aventail.com>, Roy Fielding]
7511 *) PORT: Improved compilation and DSO support on Sequent DYNIX/ptx.
7512 [Ian Turner <iant sequent.com>] PR#4735
7514 *) Local struct mmap in http_core.c conflicted with system structure
7515 name on DYNIX -- changed to mmap_rec. [Roy Fielding] PR#4735
7517 *) Added updated mod_digest as modules/experimental/mod_auth_digest.
7518 [Ronald Tschalär <ronald innovation.ch>]
7520 *) Fix a memory leak where the module counts were getting messed
7521 up across restarts. [David Harris <dharris drh.net>]
7523 *) CIDR addresses such as a.b.c.d/24 where d != 0 weren't handled
7524 properly in mod_access.
7525 ["Paul J. Reder" <rederpj raleigh.ibm.com>] PR#4770
7527 *) RewriteLock/RewriteMap didn't work properly with virtual hosts.
7528 [Dmitry Khrustalev <dima bog.msu.su>] PR#3874
7530 *) PORT: Support for compaq/tandem/com.
7531 [Michael Ottati <michael.ottati compaq.com>, dirkx]
7533 *) Added SHA1 password encryption support to easy migration from
7534 Netscape servers. See support/SHA1 for more information.
7535 Caused the separation of ap_md5.c into md5, sha1 and a general
7536 ap_checkpass.c with just a validate_passwd routine. Added a
7537 couple of flags to support/htpasswd. Some reuse of the to64()
7538 function; hence renamed to ap_to64().
7539 [Dirk-Willem van Gulik, Clinton Wong <clintdw netcom.com>]
7541 *) Change for EBCDIC platforms (TPF and BS2000) to correctly deal
7542 with ASCII/EBCDIC conversions in "ident" query.
7543 [David McCreedy <McCreedy us.ibm.com>]
7545 *) Get rid of redefinition warning on MAC_OS_X_SERVER platform.
7546 Change "Power Macintosh" to Power* so if uname prints "Power Book"
7547 we're still happy on Rhapsody platforms. [Wilfredo Sanchez]
7549 *) Fix SIGSEGV on some systems because the Vary fix below included
7550 a call to table_do with a variable argument list that was not
7551 NULL terminated. Replaced with better implementation. [Roy Fielding]
7553 Changes with Apache 1.3.7 [not released]
7555 *) The "Vary" response header field is now sanitised right before
7556 the header is sent back to the client. Multiple "Vary" fields
7557 are combined, and duplicate tokens (e.g., "Vary: host, host" or
7558 "Vary: host, negotiate, host, accept-language") are reduced to
7559 single instances. This is a better solution than the force-no-vary
7560 one (which is still valid for clients that can't cope with Vary
7561 at all). PR#3118 [Dean Gaudet, Roy Fielding, Ken Coar]
7563 *) Portability changes for BeOS. [David Reid <abb37 dial.pipex.com>]
7565 *) Link DSO's with "gcc -shared" instead of "ld -Bshareable" at
7566 least on Linux and FreeBSD for now.
7569 *) Win32: More apache -k restart work. Restarts are now honored
7570 immediately and connections in the listen queue are -not- lost.
7571 This is made possible by the use of the WSADuplicateSocket()
7572 call. The listeners are opened in the parent, duplicated, then
7573 the duplicates are passed to the child. The original listen sockets
7574 are not closed by the parent across a restart, thus the listen queue
7576 [Bill Stoddard <stoddard raleigh.ibm.com>]
7578 *) Fix handling of case when a client has sent "Expect: 100-continue"
7579 and we are going to respond with an error, but get stuck waiting to
7580 discard the body in the pointless hope of preserving the connection.
7581 [Roy Fielding, Joe Orton <jeo101 york.ac.uk>] PR#4499, PR#3806
7583 *) Fix 'configure' to work correctly with SysV-based versions of
7584 'tr' (consistent with Configure's use as well). [Jim Jagielski]
7586 *) apxs: Add "-S var=val" option which allows for override of CFG_*
7587 built-in values. Add "-e" option which works like -i but doesn't
7588 install the DSO; useful for editing httpd.conf with apxs. Fix
7589 editing code so that multiple invocations of apxs -a will not
7590 create duplicate LoadModule/AddModule entries; apxs can now be
7591 used to re- enable/disable a module. [Wilfredo Sanchez]
7593 *) Win32: Update the server to use Winsock 2. Specifically, link with
7594 ws2_32.lib rather than wsock32.lib. This gives us access to
7595 WSADuplcateSocket() in addition to some other enhanced comm APIs.
7596 Win 95 users may need to update their TCP/IP stack to pick up
7597 Winsock 2. (See http://www.microsoft.com/windows95/downloads/)
7598 [Bill Stoddard <stoddard raleigh.ibm.com>]
7600 *) Win32: Redirect CGI script stderr (script debug info) into the
7601 error.log when CGI scripts fail. This makes Apache on Win32
7602 behave more like Unix.
7603 [Bill Stoddard <stoddard raleigh.ibm.com>]
7605 *) Fixed `httpd' usage display: -D was missing.
7606 [Ralf S. Engelschall] PR#4614
7608 *) Fix `make r' test procedure in src/regex/: ap_isprint was not found.
7609 [Ralf S. Engelschall] PR#4561, PR#4562
7611 *) OS/2: Fix problem with accept lock semaphores where server would die with
7612 "OS2SEM: Error 105 getting accept lock. Exiting!"
7613 [Brian Havard] PR#4505
7615 *) Add DSO support for DGUX 4.x using gcc. Tested on x86 platforms.
7616 [Randy Terbush <randy covalent.net>]
7618 *) Add the new mass-vhost module (mod_vhost_alias.c) developed and
7619 used by Demon Internet, Ltd. [Tony Finch <fanf demon.net>]
7621 *) Better GCC detection for DSO flags under Solaris 2 where the `cc'
7622 command potentially _is_ GCC. [Ralf S. Engelschall]
7624 *) Fix apxs build issues on AIX
7625 [Rasmus Lerdorf <rasmus raleigh.ibm.com>]
7627 *) DocumentRoot Checking: Under previous versions, when Apache
7628 first started up, it used to do a stat of each DocumentRoot to
7629 see if it existed and was a directory. If not, then an error
7630 message was printed. THIS HAS BEEN DISABLED. If DocumentRoot
7631 does not exist, you will get error messages in error_log. If
7632 the '-t' command line option is used (to check the configuration)
7633 the check of DocumentRoot IS performed. An additional command
7634 line option, '-T', has been added if you want to avoid the
7635 DocumentRoot check even when checking the configuration.
7638 *) Win32: The query switch "apache -S" didn't exit after showing the
7639 vhost settings. That was inconsistent with the other query functions.
7640 [Bill Stoddard - Fixed by Martin on Unix in 1.3.4]
7642 *) Win32: Changed behaviour of apache -k restart.
7643 Previously, the server would drain all connections in the stack's
7644 listen queue before honoring the restart. On a busy server, this
7645 could take hours. Now, a restart is honored almost immediately.
7646 All connections in Apache's queues are handled but connections in
7647 the stack's listen queue are discarded. Restart triggered by
7648 MaxRequestPerChild is unchanged.
7649 [Bill Stoddard <stoddard raleigh.ibm.com>]
7651 *) Win32: Eliminated unnecessary call to wait_for_multiple_objects in
7652 the accept loop. Good for a 5% performance boost. Cleaned up
7653 parent/child process management code.
7654 [Bill Stoddard <stoddard raleigh.ibm.com>]
7656 *) Added ceiling on file size for memory mapped files.
7657 [John Giannandrea <jg meer.net>] PR#4122
7659 *) Fix ndbm.h include problems with brain-dead glibc >= 2.1 which
7660 has ndbm.h in a non-standard db1/ subdir. PR#4431, PR#4528
7661 [Henri Gomez <gomez slib.fr>, Ralf S. Engelschall]
7663 *) Determine AP_BYTE_ORDER for ap_config_auto.h and already
7664 use this at least for Expat. [Ralf S. Engelschall]
7666 *) Allow .module files to specify libraries with Lib:.
7669 *) Allow SetEnvIf[NoCase] to test environment variables as well
7670 as header fields and request attributes. [Ken Coar]
7672 *) Fix mod_autoindex's handling of ScanHTMLTitles when file
7673 content-types are "text/html;parameters". PR#4524 [Ken Coar]
7675 *) Remove "mxb" support from mod_negotiation -- it was a draft feature
7676 never accepted into any standard, and it opens up certain DoS
7677 attacks. [Koen Holtman <Koen.Holtman cern.ch>]
7679 *) TestCompile updated. We can now run programs and output the
7680 results during the Configure process. [ Jim Jagielski]
7682 *) The source is now quad (long long) aware as needed. Specifically,
7683 the Configure process determines the correct size of off_t and
7684 *void. When the OS/platform/compiler supports quads, ap_snprintf()
7685 provides for the 'q' format qualifier (if quads are not available,
7686 'q' is silently "demoted" to long). [Jim Jagielski]
7688 *) When the username or password fed to htpasswd is too long, include the
7689 size limit in the error message. Also report illegal characters
7690 (currently only ':') in the username. Add the size restrictions
7691 to the man page. [Ken Coar]
7693 *) Fixed the configure --without-support option so it doesn't result in
7694 an infinite loop. [Marc Slemko]
7696 *) Piped error logs could cause a segfault if an error occured
7697 during configuration after a restart.
7698 [Aidan Cully <aidan panix.com>] PR#4456
7700 *) If a "Location" field was stored in r->err_headers_out rather
7701 than r->headers_out, redirect processing wouldn't find it and
7702 the server would core dump on ap_escape_html(NULL). Check both
7703 tables and raise HTTP_INTERNAL_SERVER_ERROR with a log message
7704 if Location isn't set. [Doug MacEachern, Ken Coar]
7706 *) Add RULE_EXPAT, the src/lib/ directory structure, and a modified copy
7707 of the Expat 1.0.2 distribution. [Greg Stein]
7709 *) Replace regexec() calls with calls to a new API stub function
7710 ap_regexec(). This solves problems with DSO modules which use the regex
7711 library. [Jens-Uwe Mager <jum helios.de>, Ralf S. Engelschall]
7713 *) Add 'Request_Protocol' special keyword to mod_setenvif so that
7714 environment variables can be set according to the protocol version
7715 (e.g., HTTP/0.9 or HTTP/1.1) of the request. [Ken Coar]
7717 *) Add DSO support for OpenStep (Mach 4.2) platform.
7718 [Ralf S. Engelschall, Rex Dieter <rdieter math.unl.edu>] PR#3997
7720 *) Fix sed regex for generating ap_config_auto.h in src/Configure.
7721 [Jan Gallo <gallo pvt.sk>] PR#3690, PR#4373
7723 *) Switch to /bin/sh5 in APACI on Ultrix and friends to avoid problems with
7724 their brain-dead /bin/sh. [Ralf S. Engelschall] PR#4372
7726 *) Better DSO flags recognition on NetBSD platforms using ELF.
7727 [Todd Vierling <tv pobox.com>] PR#4310
7729 *) Always log months in english format for %t in mod_log_config.
7730 [Petr Lampa <lampa fee.vutbr.cz>] PR#4366, 679
7732 *) Support for server-parsed and multiview-determined ReadmeName and
7733 HeaderName files in mod_autoindex. Removed the restriction on
7734 "/"s in ReadmeName and HeaderName directives since the *sub_req*
7735 routines will deal with the access issues. (It's now possible to
7736 have {site|group|project|customer|...} wide readmes and headers.)
7737 [Raymond S Brand <rsbx rsbx.net>, Ken Coar] PR#1574, 3026, 3529,
7740 *) When stat() fails, don't assume anything about the contents of
7741 the struct stat. [Ed Korthof <ed bitmechanic.com>]
7743 *) It's OK for a semop to return EINTR, just loop around and try
7744 again. [Dean Gaudet]
7746 *) Fix configuration engine re-entrant hangups, which solve a
7747 handful of problems seen with mod_perl <Perl> configuration sections
7748 [Salvador Ortiz Garcia <sog msg.com.mx>]
7750 *) Mac OS and Mac OS X Server now use the appropriate custom layout
7751 by default when building with APACI; allow for platform-specific
7752 variable defaults in configure. [Wilfredo Sanchez]
7754 *) Do setgid() before initgroups() in http_main; some platforms
7755 zap the grouplist when setgid() is called. This was fixed in
7756 suexec earlier, but the main httpd code missed the change.
7757 [Rob Saccoccio <robs InfiniteTechnology.com>] PR#2579
7759 *) Add recognition of .tgz as a gzipped tarchive.

7762 *) mod_include's fsize/flastmod should allow only relative paths, just
7763 like "include file". [Jaroslav Benkovsky <benkovsk pha.pvt.cz>]
7765 *) OS/2: Add support for building loadable modules using DLLs.
7768 *) Add iconsdir, htdocsdir, and cgidir to config.layout.
7771 *) Fix minor but annoying bug with the test for Configuration.tmpl
7772 being newer than Configuration so that it is less likely to fail
7773 when using APACI and shadow sources. [Wilfredo Sanchez]
7775 *) PORT: Add initial support for Mac OS (versions 10.0 and
7776 greater). Use Mac OS X Server layout for now. Clean up dyld code
7777 in unix/os.c, and don't install the dyld error handlers, which
7778 are no longer needed in Mac OS. [Wilfredo Sanchez]
7780 *) Rename Rhapsody layout to "Mac OS X Server". Change install
7781 locations to appropriate ones for user-built (as opposed to
7782 system) installs. [Wilfredo Sanchez]
7784 *) Modify mod_autoindex's handling of AddDescription so that the
7785 behaviour matches the documentation. [Ken Coar] PR#1898, 3072.
7787 *) Add functionality to the install-bindist.sh script created by
7788 binbuild.sh to use tar when copying distribution files to the
7789 serverroot. This allows upgrading an existing installation
7790 without nesting the new distribution in the old.
7792 install-bindist.sh now detects the local perl5 path to install
7793 apxs and dbmmanage with proper path to perl interpreter.
7795 Add an install-binsupport target which copies the source files
7796 for apxs and dbmmanage to bindist to allow these scripts to
7797 be properly installed relative to the destination serverroot.

7877 *) "IndexOptions None" generated extra spaces at the end of each
7878 line. [<inkling firstnethou.com>] PR#3770
7880 *) The "100 Continue" response wasn't being sent after internal
7881 redirects. [Jose KAHAN <kahan w3.org>] PR#3910, 3806, 3575
7883 *) When padding the name with spaces for display, mod_autoindex would
7884 count &, <, and > in their escaped width, messing up the display.

7901 *) Fix a memory leak which is exacerbated by certain configurations.
7902 [Dean Gaudet] PR#4225
7904 *) Prevent clobbering saved IFS values in APACI. [Jim Jagielski]
7906 *) Fix buffer overflows in ap_uuencode and ap_uudecode pointed out
7907 by "Peter 'Luna' Altberg <peter altberg.nu>" and PR#3422
7908 [Peter 'Luna' Altberg <peter altberg.nu>, Ronald Tschalär]
7910 *) Make {Set,Unset,Pass}Env per-directory instead of per-server.
7913 *) Correct an apparent typo: on the Windows and MPE platforms, the
7914 htpasswd utility was limiting passwords to only 8 characters.
7917 *) EBCDIC platforms: David submitted patches for two bugs in the
7918 MD5 digest port for EBCDIC machines:
7919 a) the htdigest utility overwrote the old contents of the digest file
7920 b) the Content-MD5 header value (ContentDigest directive) was wrong
7921 when the returned file was not converted from EBCDIC, but was a
7922 binary (e.g., image file) in the first place.
7923 [David McCreedy <mccreedy us.ibm.com>]
7925 *) support/htpasswd now permits the password to be specified on the
7926 command line with the '-b' switch. This is useful when passwords
7927 need to be maintained by scripts -- particularly in the Win32
7928 environment. [Ken Coar]
7930 *) Win32: Win32 multiple services patch. Added capability to install and
7931 run multiple copies of apache as individual services.
7934 apache -n apache1 -i -f c:/httpd.conf
7935 Installs apache as service 'apache1' and associates c:/httpd.conf
7938 Starts apache1 service.
7940 Stops apache1 service
7943 apache -n apache2 -i
7944 Installs apache as service 'apache2'. httpd.conf is located under
7945 the default server root (/apache/conf/httpd.conf).
7947 Starts apache2 service.
7950 apache -n apache3 -i -d c:/program files/apache
7951 Install apache as service 'apache3' and sets server root to
7952 c:/program files/apache.
7955 apache -n apache2 -k restart
7956 Restart apache2 service
7958 [Keith Wannamaker, Ken Parzygnat, Bill Stoddard]
7960 *) Correct the signed/unsigned character handling for the MD5 routines;
7961 mismatches were causing compilation problems with gcc -pedantic and
7962 in the TPF cross-compilation. [Ken Coar]
7964 *) OS/2: Rework CGI handling to use spawn*() instead of fork/exec, achieving
7965 a roughly 5 fold speed up. [Brian Havard]
7967 *) proxy ftp: instead of using the hardwired string "text/plain" as
7968 a fallback type for files served by the ftp proxy, use the
7969 ap_default_type() function to determine the configured type.
7970 This allows for special configurations like
7971 <Directory proxy:ftp://some.host>
7972 DefaultType gargle/blurb
7974 Additionally, add the Content-Encoding: header to FTP proxy replies
7975 when the encoding is defined (by the AddEncoding directive).
7976 Because it was missing, it was almost impossible to browse compressed
7977 files using the FTP proxy (works now perfectly in Communicator).
7978 The ftp proxy now also returns the Date: and Server: header lines (if not
7979 much else... This code is "somewhat" broken) like normal requests do.
7982 *) Be more smart in APACI's configure script when determining the UID/GID
7983 for User/Group directives and use the determined UID/GID to initialize
7984 the permissions on the proxycachedir.
7985 [Dirk-Willem van Gulik, Ralf S. Engelschall]
7987 *) Changed the forking-prior-to-cleanup in the proxy module to first
7988 check wether it actually needs to collect garbage. This reduces
7989 the number of fork()s from one/request to just the odd one an hour.
7990 [Dirk-Willem van Gulik]
7992 *) Added proxy, auth and header support to src/support/ab.c. Added a
7993 README file to src/support/
7994 [Dirk-Willem van Gulik]
7996 *) Don't hard-code the path to AWK in --shadow bootstrapping Makefile.
7997 [Ralf S. Engelschall] PR#4050
7999 *) Add support for DSO module compilation on BSD/OS 3.x.
8000 [Randy Terbush, Covalent Technologies]
8002 *) Fix sed-substitutions in `make install': path elements like `httpd/conf'
8003 (for instance from an APACI configure --sysconfdir=/etc/httpd/conf
8004 option) were substituted with $(TARGET).conf, etc. Same for other strings
8005 with dots where the dot wasn't matched as plain text.
8006 [Ralf S. Engelschall]
8008 *) PORT: Add support for FreeBSD 4.x [Ralf S. Engelschall]
8010 *) Fix verbose output of APACI configure (option -v)
8011 [Martin Kraemer, Ralf S. Engelschall]
8013 Changes with Apache 1.3.6
8015 *) Removed new PassAllEnv code due to DSO problems. [Lars Eilebrecht]
8017 Changes with Apache 1.3.5 [not released]
8019 *) M_INVALID needed a value within the scope of METHODS so that unknown
8020 methods can be access controlled. [Roy Fielding] PR#3821
8022 *) Added PassAllEnv; makes server's entire environment available
8023 to CGIs and SSIs executed within directive's scope. [Ken Coar]
8025 *) ap_uuencode() always added two trailing '='s and encoding of
8026 8 bit characters on a machine with signed char may produced
8027 incorrect results. Additionally ap_uuencode() should now
8028 work correctly on EBCDIC platforms.
8029 [Ronald Tschalär <ronald innovation.ch>] PR#3411
8031 *) WIN32: Binary installer now runs the configuration DLL before
8032 the reboot prompt (which is only given if MSVCRT.DLL system
8033 DLL is new or updated). This should avoid the configuration
8034 directory being empty after installation. [Paul Sutton]
8035 PR#3767, 3800, 3827, 3850, 3900, 3953, 3988
8037 *) WIN32: Binary installer now creates Start menu options to start
8038 and stop Apache as a console application and to uninstall
8039 the Apache service on NT. [Paul Sutton] PR#3741
8041 *) WIN32: Apache.exe now contains an icon. [Paul Sutton]
8043 *) PORT: Switch back to using fcntl() locking on Linux -- instabilities
8044 have been reported with flock() locking (probably related to kernel
8045 version). [Dean Gaudet] PR#2723, 3531
8047 *) Using APACI, the main config file (usually httpd.conf) was
8048 not being adjusted as $(TARGET).conf. [Wilfredo Sanchez
8049 <wsanchez apple.com>]
8051 *) PORT: AIX does not require the SHARED_CODE "hack"
8052 [Ryan Bloom <rbb raleigh.ibm.com>]
8054 *) Set-Cookie headers were being doubled up for some CGIs by the O(n^2)
8055 avoidance code added in 1.3.3.
8056 [Dean Gaudet, Jeff Lewis <lewis stanford.edu>] PR#3872
8058 *) ap_isxdigit was somehow neglected when adding the ap_isfoo() macros
8059 for 8-bit safeness. [Dean Gaudet]
8061 *) PORT: Use -fPIC instead of -fpic on Solaris and SunOS for compiling DSOs
8062 because SPARCs have a small machine-specific maximum size for the Global
8063 Offset Table which is often exceeded when compiling one of the larger
8064 third-party modules with Apache. [Peter Urban <Peter.Urban epfl.ch>] PR#3977
8066 *) Move the directive `ExtendedStatus' in httpd.conf-dist-win _after_ the
8067 DSO/DLL section because it's a directive from mod_status and isn't
8068 available before the DLL of mod_status is loaded.
8069 [Martin POESCHL <mpoeschl gmx.net>] PR#3936
8071 *) SECURITY: Fix a bug in the calculation of the buffer size for the line
8072 continuation facility in Apache's configuration files which could
8073 lead to a buffer overflow situation.
8074 [Thomas Devanneaux <Thomas.Devanneaux enst.fr>] PR#3617
8076 *) Make documentation and error messages of APACI's --activate-module=FILE
8077 option more clear. [Jan Wolter <janc wwnet.net>] PR#3995
8079 *) Fix the gcc version check (for enabling the `inline' facility) to
8080 really support all future gcc versions >= 2.7 until we know more.
8081 [John Tobey <jtobey banta-im.com>] PR#3983
8083 *) Let APACI's configure script correctly complain for unknown --enable-XXX
8084 and --disable-XXX options. [Ralf S. Engelschall] PR#3958
8086 *) Link the shared core bootstrap program (``Rule SHARED_CORE=yes'') also
8087 against libap.a and use its ap_snprintf() instead of sprintf() to avoid
8088 possible buffer overflows. [Ralf S. Engelschall]
8090 *) Remove no longer used non-API function ap_single_module_init().
8091 [Ralf S. Engelschall]
8093 *) Add Apple's Mac OS X Server Layout "Rhapsody" to config.layout.
8096 *) Add cgidir, htdocsdir, iconsdir variables to Makefile.tmpl in order
8097 to make platform installations easier. [Wilfredo Sanchez]
8099 *) In configure, do not append the target name to the directory path if
8100 the path already contains "apache". [Ralf S. Engelschall]
8102 *) SIGPIPE is now ignored by the server core. The request write routines
8103 (ap_rputc, ap_rputs, ap_rvputs, ap_rwrite, ap_rprintf, ap_rflush) now
8104 correctly check for output errors and mark the connection as aborted.
8105 Replaced many direct (unchecked) calls to ap_b* routines with the
8106 analogous ap_r* calls. [Roy Fielding]
8108 *) Enhanced mod_rewrite's mapfile handling: The in-core cache for text and
8109 DBM format mapfiles now uses a 4-way hash table with LRU functionality.
8110 Furthermore map lookups for non-existent keys are now cached as well.
8111 Additionally "txt" maps are now parsed with simple string functions
8112 instead of using ap_pregcomp(). As a side effect a bug that prevented
8113 the usage of keys containing the "," character was fixed.
8114 The changes drastically improve the performance when large rewrite maps
8116 [Michael van Elst <mlelstv serpens.swb.de>, Lars Eilebrecht] PR#3160
8118 *) Added ap_sub_req_method_uri() for doing a subrequest with a method
8119 other than GET, and const'd the definition of method in request_rec.
8122 *) Use proper pid_t type for saving PIDs in alloc.c. [John Bley]
8124 *) Replaced use of WIN32 define with HAVE_DRIVE_LETTERS to indicate
8125 when the OS allows a DOS drive letter within pathnames. [Brian Havard]
8127 *) Add %V to mod_log_config, this logs the hostname according to the
8128 UseCanonicalName setting (this is the pre-1.3.4 behaviour of
8129 %v). Useful for mass vhosting. [Tony Finch <dot dotat.at>]
8131 *) Add support for \n and \t to mod_log_config, can be used to produce
8132 more reliable logs with multiline entries. [Tony Finch <dot dotat.at>]
8134 *) Fixed a few compiler nits. [John Bley <jbb6 acpub.duke.edu>]
8136 *) Added informative error messages for failed munmap() and fseek() calls
8137 in http_core.c. [John Bley, Roy Fielding]
8139 *) Added some informative error messages for some failed malloc()
8140 calls. [John Bley <jbb6 acpub.duke.edu>, Jim Jagielski]
8142 *) OS/2 ap_os_canonical_filename()'s behaviour is improved: ap_assert()
8143 is removed. This allows <Directory proxy:*> directives to work and
8144 prevents invalid requests from killing the process.
8145 [Brian Havard <brianh kheldar.apana.org.au>]
8147 *) Reorganised FAQ document.
8148 [Joshua Slive <slive finance.commerce.ubc.ca>] PR#2497
8150 *) src/support/: The ApacheBench benchmark program was overhauled by
8151 David N. Welton: you can now have it generate an HTML TABLE, presumably
8152 for integration into other HTML sources. David updated the ab man page
8153 as well and added some missing descriptions. Thanks!
8154 [David N. Welton <davidw prosa.it>]
8156 *) Win32: The filename validity checker now allows filenames containing
8157 characters in the range 0x80 to 0xff (for example accented characters).
8158 [Paul Sutton] PR#3890
8160 *) Added conditional logging based upon environment variables to
8161 mod_log_config. mod_log_referer and mod_log_agent
8162 are now deprecated. [Ken Coar]
8164 *) Allow apache acting as a proxy server to relay the real
8165 reason of a failure to a client rather than the "internal
8166 server error" it does currently. The general exposure mechanism
8167 can be triggered by any module by setting the "verbose-error-to"
8168 note to "*"; this allows more than just proxy errors to be exposed.
8169 [Cliff Skolnick, Roy Fielding, Martin Kraemer] Related to PR#3455, 4086
8171 *) Moved man pages for ab and apachectrl to section 8.
8172 [Wilfredo Sanchez, Roy Fielding]
8174 *) Added -S option to install.sh so that options can be passed to
8175 strip on some platforms. [Ralf S. Engelschall, Wilfredo Sanchez]
8177 *) Tweak modules Makefile generated by Configure so that it handles
8178 the test case of no modules being selected. [<chaz reliant.com>]
8180 *) Added a <LimitExcept method ...> sectioning directive that allows
8181 the user to assign authentication control to any HTTP method that
8182 is *not* given in the argument list; i.e., the logical negation
8183 of the <Limit> directive. This is particularly useful for controlling
8184 access on methods unknown to the Apache core, but perhaps known by
8185 some module or CGI script. [Roy Fielding, Tony Finch]
8187 *) Prevent apachectl from complaining if the PIDFILE exists but
8188 does not contain a process id, as might occur if the server is
8189 being rapidly restarted. [Wilfredo Sanchez]
8191 *) Win32: Add global symbols missing from ApacheCore.def. [Carl Olsen]
8193 *) Entity tag comparisons for If-Match and If-None-Match were not being
8194 performed correctly -- weak tags might cause false positives. Also,
8195 strong comparison wasn't properly enforced in all cases.
8196 [Roy Fielding, Ken Coar, Dean Gaudet] PR#2065, 3657
8198 *) OS/2: Supply OS/2 error code instead of errno on semaphore errors.
8201 *) Work around a bug in Lynx regarding its sending "Negotiate: trans"
8202 even though it doesn't understand TCN. [Koen Holtman, Roy Fielding]
8204 *) Added ap_size_list_item(), ap_get_list_item(), and ap_find_list_item()
8205 to util.c for parsing an HTTP header field value to extract the next
8206 list item, taking into account the possible presence of nested comments,
8207 quoted-pairs, and quoted-strings. ap_get_list_item() also removes
8208 insignificant whitespace and lowercases non-quoted tokens.
8209 [Roy Fielding] PR#2065
8211 *) proxy: The various calls to ap_proxyerror() can return HTTP/1.1 status
8212 code different from 500. This allows the proxy to, e.g., return
8213 "403 Forbidden" for ProxyBlock'ed URL's. [Martin Kraemer] Related to PR#3455
8215 *) Fix ordering of language variants for the case where the traditional
8216 negotiation algorithm is being used with multiple language variants
8217 and no Accept-Language. [James Treacy <treacy debian.org>] PR#3299, 3688
8219 *) Do not round the TCN quality calculation to 5 decimal places,
8220 unlike RFC 2296, because the calculation might need 12 decimal places
8221 to get the right result. [Roy Fielding]
8223 *) Remove unused code to disable transparent negotiation when
8224 negotiating on encoding only, as we now handle encoding too
8225 (though this is nonstandard for TCN), remove charset=ISO-8859-1
8226 fiddle from the fiddle-averse RVSA comparison, and fix bugs in
8227 some debugging statements within mod_negotiation. [Koen Holtman]
8229 *) Fixed a rare memory corruption possibility in mod_dir if the index
8230 file is negotiable and no acceptable variant can be found.
8231 [Dean Gaudet, Roy Fielding, Martin Kraemer]
8233 *) Win32: Add new config directive, ScriptInterpreterSource, to enable
8234 searching the Win32 registry for script interpreters.
8237 *) Win32: The compiled-in default filename for the error log is now
8238 error.log, which matches the default in the distributed httpd.conf.
8241 *) Win32: Any error messages from -i or -u command line options are now
8242 displayed on the console output rather than sent to the error log.
8243 Also the "Running Apache..." message is not output unless Apache is
8244 going to serve requests. [Paul Sutton]
8246 *) Rework the MD5 authentication scheme to use FreeBSD's algorithm,
8247 and use a private significator ('$apr1$') to mark passwords as
8248 being smashed with our own algorithm. Also abstract the password
8249 checking into a new ap_validate_password() routine. [Ken Coar]
8251 *) Win32: The filename validity checker now allows "COM" but refuses
8252 access to "COM1" through "COM4". This allows filenames such
8253 as "com.name" to be served. [Paul Sutton] PR#3769.
8255 *) BS2000: Adapt to the new ufork() system call interface which will
8256 make subtasking easier on the OSD/POSIX mainframe environment.
8259 *) Add a compatibility define for escape_uri() -> ap_escape_uri() to
8260 ap_compat.h. [David White <david persimmon.com>] PR#3725
8262 *) Make NDBM file suffix determination for mod_rewrite more accurate, i.e.
8263 use `.db' instead of `.pag' not only for FreeBSD, but also when
8264 the NDBM library looks like Berkeley-DB based.
8265 [Ralf S. Engelschall] PR#3773
8267 *) Add ability to handle DES or MD5 authentication passwords.
8268 [Ryan Bloom <rbb Raleigh.IBM.Com>]
8270 *) Fix O(n^2) memory consumption in mod_speling. [Dean Gaudet]
8272 *) SECURITY: Avoid some buffer overflow problems when escaping
8273 quoted strings. (This overflow was on the heap and we believe
8274 impossible to exploit.) [Rick Perry <perry ece.vill.edu>]
8276 *) Let src/Configure be aware of CFLAGS options starting with plus
8277 signs as it's the case for the HP/UX compiler.
8278 [Doug Yatcilla <yatcilda umdnj.edu>] PR#3681
8280 *) Remove the hard-wire of TAR=tar (we now check for gtar and gnutar first)
8281 and check to see if the tar we wind up with supports '-h'.
8282 [Jim Jagielski] PR#3671
8284 *) A consistent and conservative style for all shell scripts has been
8285 implemented. Basically, all shell string tests use the traditional
8286 hack of 'if [ "x$var" != "x" ]' or 'if [ "x$var" = "xstring" ]'
8287 to protect against bare null variable strings (ie: wrapping both
8288 sides with double quotes and prepending 'x'). 'x' was chosen
8289 because it's more universal and hopefully easier for old shell
8290 prgrammers, as well as being easier to search for in 'vi' (/x\$) :)
8293 *) The status module now prints out both the main server generation as
8294 well as the generation of each process. Also, the vhost info is
8295 printed with '?notable'. [Jim Jagielski]
8297 *) Move src/main/md5c.c to src/ap/ap_md5c.c; it's httpd-neutral
8298 and this makes its functions available to things in src/support.
8301 Changes with Apache 1.3.4
8303 *) Renamed macros status_drops_connection to ap_status_drops_connection
8304 and vestigial scan_script_header to ap_scan_script_header_err,
8305 mostly for aesthetic reasons. [Roy Fielding]
8307 *) The query switch "httpd -S" didn't exit after showing the
8308 vhost settings. That was inconsistent with the other query functions.
8311 *) Moved the MODULE_MAGIC_COOKIE from before the versions and
8312 filename to the end of the STANDARD_MODULE_STUFF. Its
8313 presence at the beginning prevented reporting of the filename
8314 for modules compiled before 1 January 1999. [Ken Coar]
8316 *) SECURITY: ap_os_is_filename_valid() has been added to Win32
8317 to detect and prevent access to special DOS device file names.
8318 [Paul Sutton, Ken Parzygnat]
8320 *) WIN32: Created new makefiles Makefile_win32.txt (normal build)
8321 and Makefile_win32_debug.txt (debug build) that work on Win95.
8322 Run each of the following from the src directory:
8323 nmake /f Makefile_win32.txt # compiles normal build
8324 nmake /f Makefile_win32.txt install # compiles and installs
8325 nmake /f Makefile_win32.txt clean # removes compiled junk
8326 nmake /f Makefile_win32_debug.txt # compiles debug build
8327 nmake /f Makefile_win32_debug.txt install
8328 nmake /f Makefile_win32_debug.txt clean
8331 *) Added binbuild.sh and findprg.sh helpers to make it easier for us
8332 to build binary distributions. [Lars Eilebrecht]
8334 *) IndexOptions SuppressColumnSorting only turned off making
8335 the column headers anchors; you could still change the display
8336 order by manually adding a '?N=A' or similar query string to the
8337 URL. Now SuppressColumnSorting locks in the sort order so
8338 it can't be overridden this way. [Ken Coar]
8340 *) Added IndexOrderDefault directive to supply a default sort order
8341 for FancyIndexed directory listings. [Ken Coar] PR#1699
8343 *) Change the ap_assert macro to a variant that works on all platforms.
8344 [Richard Prinz <richard.prinz cso.net>] PR#2575
8346 *) Make sure under ELF-based NetBSD (now) and OpenBSD (future) we don't
8347 search for an underscore on dlsym() (as it's already the case
8348 for FreeBSD 3.0). [Todd Vierling <tv pobox.com>] PR#2462
8350 *) Small fix for mod_env.html: The module was documented as to be _not_
8351 compiled into Apache per default, although it _IS_ compiled into
8352 Apache per default. [Sim Harbert <sim mindspring.com>] PR#3572
8354 *) Instead of fixing a bug in the generation procedure for config.status (a
8355 backslash was missing) we remove the bug together with it's complete
8356 context because the special cases of the past can now no longer occur
8357 because of the recent magic for the --with-layout default.
8358 [Ralf S. Engelschall] PR#3590
8360 *) Make top-level Makefile aware of a parallel build procedures (make -j) by
8361 making sure the src/support/ tools are _forced_ to be build last (they
8362 depend on other libraries).
8363 [Markus Theissinger <markus.theissinger gmx.de>]
8365 *) Fix installation procedure: Now that os-inline.c is actually used (a
8366 recently fixed bug prevented this) we need to also install os-include.c
8367 in addition to os.h into the PREFIX/include/ location or building of
8368 module DSOs with APXS fails. [Ralf S. Engelschall] PR#3527
8370 *) Added MODULE_MAGIC_COOKIE as the first field in a module structure to
8371 allow us to distinguish between a garbled DSO (or even a file which isn't
8372 an Apache module DSO at all) and a DSO which doesn't match the current
8373 Apache API. [Ralf S. Engelschall] PR#3152
8375 *) Two minor enhancements to mod_rewrite: First RewriteRule now also
8376 supports the ``nocase|NC'' flag (as RewriteCond already does for ages) to
8377 match case insensitive (this especially avoids nasty patterns like
8378 `[tT][eE][sS][tT]'). Second two additional internal map functions
8379 `escape' and `unescape' were added which can be used to escape/unescape
8380 to/from hex-encodings in URLs parts (this is especially useful in
8381 combination with map lookups).
8382 [Magnus Bodin, Ian Kallen, Ralf S. Engelschall]
8384 *) Renamed the macro escape_uri() to ap_escape_uri() which was
8385 forgotten (because it was a macro) in the symbol renaming process.
8386 [Ralf S. Engelschall]
8388 *) Fix some inconsistencies related to the scopes of directives. The only
8389 user visible change is that the directives `UseCanonicalName' and
8390 `ContentDigest' now use the (more correct) `Options' scope instead of
8391 (less correct) `AuthConfig' scope. [Ralf S. Engelschall]
8393 *) Using DSO, the Server token was being mangled. Specifically, the
8394 module's token was being added first before the Apache token. This
8395 has been fixed. [Jim Jagielski]
8397 *) Major overhaul of mod_negotiation.c, part 2.
8398 - properly handle "identity" within Accept-Encoding.
8399 - allow encoded variants in RVSA negotiation and let them appear in
8400 the Alternates field using the non-standard "encoding" tag-list.
8401 - fixed both negotiation algorithms so that an explicitly accepted
8402 encoding is preferred over no encoding if "identity" is not
8403 included within Accept-Encoding.
8404 - added ap_array_pstrcat() to alloc.c for efficient concatenation
8405 of large substring sequences.
8406 - replaced O(n^2) memory hogs in mod_negotiation with ap_array_pstrcat.
8409 *) Major overhaul of mod_negotiation.c, part 1.
8410 - cleanups to mod_negotiation comments and code structure
8411 - made compliant with HTTP/1.1 proposed standard (rfc2068) and added
8412 support for everything in the upcoming HTTP/1.1
8413 revision (draft-ietf-http-v11-spec-rev-06.txt).
8414 - language tag matching also handles tags with more than 2
8416 - empty Accept, Accept-Language, Accept-Charset headers are
8417 processed correctly; previously an empty header would make all
8418 values acceptable instead of unacceptable.
8419 - allowed for q values in Accept-Encoding
8420 - added support for transparent content negotiation (rfc2295 and
8421 rfc2296) (though we do not implement all features in these drafts,
8422 e.g. no feature negotiation). Removed old experimental version.
8423 - implemented 'structured entity tags' for better cache correctness
8424 (structured entity tags ensure that caches which can deal with Vary
8425 will (eventually) be updated if the set of variants on the server
8427 - this involved adding a vlist_validator element to request_rec
8428 - this involved adding the ap_make_etag() function to the global API
8429 - modified guessing of charsets used by Apache negotiation algorithm
8430 to guess 'no charset' if the variant is not a text/* type
8431 - added code to sort multiviews variants into a canonical order so that
8432 negotiation results are consistent across backup/restores and mirrors
8433 - removed possibility of a type map file resolving to another type map
8434 file as its best variant

8464 *) Update APXS manual page: some -q option arguments were missing
8465 and another was incorrect. [Mark Anderson <mda discerning.com>] PR#3553
8467 *) Cleanup the command line options: `-?' was documented to show
8468 the usage list but does it with an error because `?' is not a valid
8469 command. OTOH a lot of users expect `-h' to print such a usage list and
8470 instead are annoyed for ages by our huge unreadable list of directives.
8471 So we now changed the command line options this way:
8473 Intent: we need `-L' to be free, and `-R' for the DSO run-time path is
8474 very similar to the popular linker option.
8476 Intent: while -l gives the small list of modules, -L now gives the
8477 large list of directives implemented by these modules. This is also
8478 consistent with -v (short version info) and -V (large version info).
8480 Intent: it's now the expected option ;-)
8481 The manual page was adjusted accordingly.

8484 *) Fixed problem of fclose() on an unopened file in suexec if LOG_EXEC
8485 wasn't defined. [Rick Franchuk <rickf transpect.net>]
8487 *) Removed recently introduced bugs and disfigurements in APACI:
8488 o fixed argument line processing: using $args was broken: It was not
8489 initialized and using args="$args $apc_option" and even args="$args
8490 \"$apc_option\"" fails in the second processing round for any arguments
8491 containing whitespaces. The only correct way is to use the construct
8492 "$@" (but not possible here) or iterate _both_ times over the implicit
8493 argument line (no argument to for-loop) which is what we now use.
8494 o make --with-layout=Apache the default without creating
8495 redundancy (copying the --with-layout block in the argument parsing
8496 loop). We achieve this by using the "$@" construct together with the
8497 `set' command to prepend --with-layout=Apache to the command line in
8498 case --with-layout is not used.
8499 o fixed auto-suffix handling now that config.layout exists.
8500 Paths which are auto-suffixed are marked with a trailing plus sign in
8501 config.layout and every path now can be marked this way (not only the
8502 four paths for which we do it currently). Additionally the suffix is
8503 no longer a static one. Instead it's now `/<target>' where <target> is
8504 the argument of the --target option or per default `httpd'.
8505 o allow also tabs (and only spaces) where we match whitespaces
8506 o various fixes and cleanups related to used shell coding style
8507 o made Jim happy by replacing `Written by' with `Initially written by' ;-)
8508 o trimmed output of --help to fit into 80 columns

8575 identifier, currently "Apache" and "GNU" are pre-defined in the file
8576 config.layout. Custom layouts are possible by using FILE:ID as the
8577 argument where the layout ID is taken from FILE.
8579 The config.layout file consists of <Layout ID>..</Layout> sections
8580 where inside those sections "path_variable: path_value" pairs can be
8581 specified. These lines are converted to path_variable='path_value'.
8583 *) Add a DefaultLanguage directive so that files missing a language
8584 extension (e.g., .fr, .de) can be labelled as being some other

8869 that missing files are not confused with unreadable files.
8872 *) The ap_pfopen and ap_pfdopen routines were failing to protect the
8873 errno on an error, which leads to one error being mistaken for
8874 another when reading non-existent .htaccess files.
8877 *) OS/2: The new header tests get things right, need to update
8878 ap_config.h. [Brian Havard]

8897 *) Fix bug in ap_remove_module(), which caused problems for dso's
8898 who were the top_module. [Doug MacEachern]
8900 *) Add support for Berkeley-DB/2.x (in addition to Berkeley-DB/1.x) to
8901 mod_auth_db to both be friendly to users who wants to use this version
8902 and to avoid problems under platforms where only version 2.x is present.
8903 [Dan Jacobowitz <drow false.org>, Ralf S. Engelschall]
8905 *) When using ap_log_rerror(), make the error message available to the
8906 *ERROR_NOTES envariables by default. [Ken Coar]
8908 *) BS2000 platform only: get rid of the nasty BS2000AuthFile.
8909 You now must define a BS2000Account name for the server User.
8910 This has fewer security implications than the old approach.
8913 *) Fix SHARED_CORE feature for HPUX platform: We now use extension `.sl'
8914 instead of `.so' and `SHLIB_PATH' instead of `LD_LIBRARY_PATH' on this
8915 platform to make the braindead HPUX linker happy. Notice, for the module
8916 DSOs we don't have to use this, because these are loaded manually (and
8917 not via HPUX' dld). [Ralf S. Engelschall] PR#2905, PR#2968

8926 platforms where `nogroup' exists in /etc/group. [Ralf S. Engelschall]
8928 *) Make PrintPath work generically instead of having one version
8929 strictly for OS/2. [Jim Jagielski, Brian Havard]
8931 *) Fix the recently introduced C header file checking: We now use the C
8932 pre-processor pass only (and no longer the complete compiler pass) to
8933 determine whether a C header file exists or not. Because only this way
8934 we're safe against inter-header dependencies (which caused horrible
8935 portability problems). The only drawback is that we now have a CPP
8936 configuration variable which has to be determined first (we do a similar
8937 approach as GNU Autoconf does here). When all fails the user still has
8938 the possibility to override it manually via APACI or src/Configuration.
8939 As a fallback for the header check itself we can directly check the
8940 existance of the file under /usr/include, too.

8972 platform, because it's only supported under version 4.0 and higher. But
8973 because our GuessOS is still unaware of Digital UNIX versions and the
8974 -msym is just to optimize the DSO statup time a little bit it's safe and
8975 best when we leave it out now. [Ralf S. Engelschall] PR#2969
8977 *) Fix the ap_log_error_old(), ap_log_unixerr() and ap_log_printf()
8978 functions: First all three functions no longer fail on strings containing
8979 "%" chars and second ap_log_printf() no longer does a double-formatting
8980 (instead it directly passes through the message to be formatted to the
8981 real internal formatting function). [Ralf S. Engelschall] PR#2941
8983 *) Allow "Include" directives anywhere in the server config
8984 files (but not .htaccess files). [Ken Coar] PR#2727
8986 *) The proxy was refusing to serve CONNECT requests except to
8987 port 443 (https://) and 563 (snews://). The new AllowCONNECT
8988 directive allows the configuration of the ports to which a
8989 CONNECT is allowed. [Sameer Parekh, Martin Kraemer]
8991 *) mod_expires will now act on content that is not sent from a file
8992 on disk. Previously it would never add an Expires: header to
8993 any response that did not come from a file on disk; the only
8994 case where it still doesn't (and can't) add one for that type of
8995 content is if you are using a modification date based setting.
8996 [Marc Slemko, Paul Phillips <paulp go2net.com>]
8998 *) Problems encountered during .htaccess parsing or CGI execution
8999 that lead to a "500 Server Error" condition now provide explanatory
9000 text (in the *ERROR_NOTES envariable) to ErrorDocument 500 scripts.
9003 *) Add NameWidth keyword to IndexOptions directive so that the
9004 width of the filename column is customisable. [Ken Coar, Dean Gaudet]
9007 *) Recognize lowercase _and_ uppercase `uname' results under
9008 SCO OpenServer. [David Coelho <drc ppt.com>]
9010 *) As duplicate "HTTP/1.0 200 OK" lines within the header seem to be
9011 a common problem of (mis-administrated?) IIS servers, make the apache
9012 proxy immune to these errors (and ignore the duplicates, but log
9013 the fact to error_log). [Martin Kraemer], after the proposal in PR#2914
9015 *) The <IfModule and <IfDefine block starting directives now only
9016 allow exactly one argument. Previously, the optional negation
9017 character '!' could be separated by whitespace without a syntax
9018 error being reported, albeit defeating the IfModule functionality
9019 (enclosed directives would ALWAYS be executed). By using the
9020 stricter syntax, these hard-to-track errors can be avoided.
9023 *) Simplify handling of IndexOptions in mod_autoindex -- and BTW
9024 cause the standalone FancyIndexing directive to logically OR
9025 into any existing IndexOptions settings rather than wiping
9026 them out. [Ken Coar]
9028 *) Changes in ftp proxy: make URL parsing simpler by using the
9030 + Add display of the "current directory" in cases where it's
9031 different from the supplied path (e.g., ftp://user@host/ lives
9032 in /home/user, not in /, therefore clicking on "../" in the
9033 starting directory might send us to /home/).
9034 + When ftp login fails, (esp. when a user name was part of the
9035 URL already), we now return [401 Unauthorized ] to allow the
9036 browser to pop up an authorization dialog. This makes passwords
9037 slightly less visible (they don't appear in the regular log files)
9038 and implements a functionality that other www proxy servers
9042 *) Triggered by the recent "Via:" header changes, the proxy module would
9043 dump core for replies with invalid headers (e.g., duplicate
9044 "HTTP/1.0 200 OK" lines). These errors are now logged and the
9045 core dump is avoided. Also, broken replies are not cached.
9046 [Martin Kraemer] PR#2914
9048 *) new `GprofDir' directive when compiled with -DGPROF, where gprof can
9049 plop gmon.out profile data for each child [Doug MacEachern]
9051 *) Use the construct ``"$@"'' instead of ``$*'' in the generated
9052 config.status script to be immune against arguments with whitespaces.
9053 [Yves Arrouye <yves apple.com>] PR#2866
9055 *) Replace the inlined information grabbing stuff for the configuration
9056 adjustment feature (no --without-confadjust) with calls to a new helper
9057 script `buildinfo.sh' which is both more flexible and already proofed to
9058 be more robust against platform differences. This mainly fixes the
9059 recently occured ``sed: command garbled: ...'' problems.
9060 [Ralf S. Engelschall] PR#2776, PR#2848
9062 *) Make ab.c again pass ``gcc -Wall -Wshadow -Wpointer-arith -Wcast-align
9063 -Wmissing-prototypes -Wmissing-declarations -Wnested-externs -Winline''
9064 without complains after we recently added the POST feature.
9065 [Ralf S. Engelschall]
9067 *) Renamed is_HTTP_xxx() macros to ap_is_HTTP_xxx() name. They are used inside
9068 modules as API functions and we forgot them at the big symbol renaming.
9069 [Ralf S. Engelschall]
9071 *) Remove bad reference to non-existing SERVER_VERSION in mod_rewrite.html

9077 *) Add the ability to do POST requests to the ab benchmarking tool.
9078 [Kurt Sussman <kls best.com>] PR#2871
9080 *) Bump up MAX_ENV_FLAGS in mod_rewrite.h from the too conservatice limit of
9081 5 to 10 because there are some users out there who always have 5 to 8
9082 variables in one RewriteRule and had to patch mod_rewrite.h for every
9083 release. So 15 should be now more than enough, even for them. (I never
9084 needed more than 4 in my RewriteRules ;-)
9085 [Ralf S. Engelschall]
9087 *) Make the proxy generate and understand Via: headers
9090 *) Change the proxy to use tables instead of array_headers for
9091 the header lines. [Martin Kraemer]
9093 *) Make sure the config.status file is not overridden when just
9094 ``configure --help'' is used. [Ralf S. Engelschall] PR#2844
9096 *) Split MODULE_MAGIC_NUMBER into _MAJOR/_MINOR numbers. This should
9097 provide a way to trace API changes that add functionality but do
9098 not create a compatibility issue for precompiled modules, etc.
9099 See include/ap_mmn.h for more details. [Randy Terbush]
9101 *) Fix suexec installation under `make install root=xxx' situation.
9102 [Ralf S. Engelschall]
9104 *) Extend the output of the -V switch to include the paths of all
9105 compiled-in configuration files, if they were overridden at
9106 compile time, for least astonishment of the user.
9109 *) When READing a request in ExtendedStatus mode, the "old"
9110 vhost, request and client information is not displayed.
9113 *) STATUS is no longer available. Full status information now
9114 run-time configurable using the ExtendedStatus directive.
9117 *) SECURITY: CVE-1999-1199 (cve.mitre.org)
9118 Eliminate O(n^2) space DoS attacks (and other O(n^2)
9119 cpu time attacks) in header parsing. Add ap_overlap_tables(),
9120 a function which can be used to perform bulk update operations
9121 on tables in a more efficient manner. [Dean Gaudet]
9123 *) SECURITY: Added compile-time and configurable limits for
9124 various aspects of reading a client request to avoid some simple
9125 denial of service attacks, including limits on maximum request-line
9126 size (LimitRequestLine), number of header fields (LimitRequestFields),
9127 and size of any one header field (LimitRequestFieldsize). Also added
9128 a configurable directive LimitRequestBody for limiting the size of the
9129 request message body. [Roy Fielding]
9131 *) Make status module aware of DNS and logging states, even if
9132 STATUS not defined. [Jim Jagielski]
9134 *) Fix a problem with the new OS/2 mutexes. [Brian Havard]
9136 *) Enhance mod_speling so that CheckSpelling can be used in
9137 <Directory> containers and .htaccess files. [Ken Coar]
9139 *) API: new ap_custom_response() function for hooking into the
9140 ErrorDocument mechanism at runtime [Doug MacEachern]
9142 *) API: new ap_uuencode() function [Doug MacEachern]
9144 *) API: scan_script_header_err_core() now "public" and renamed
9145 ap_scan_script_header_err_core() [Doug MacEachern]
9147 *) The 'status' module will now show the process pid's and their
9148 state even without full STATUS accounting. [Jim Jagielski]
9150 *) Restore the client IP address to the error log messages, this
9151 was lost during the transition from 1.2 to 1.3. Add a new
9152 function ap_log_rerror() which takes a request_rec * and
9153 formats it appropriately. [Dean Gaudet] PR#2661
9155 *) Cure ap_cfg_getline() of its nasty habit of compressing internal
9156 whitespace in input lines -- including within quoted strings.
9158 but leading and trailing whitespace should continue to be
9159 stripped [Martin Kraemer]
9161 *) Cleanup of the PrintPath/PrintPathOS2 helper functions. Avoid
9162 the ugly use of an env. variable and use command-line args for
9163 alternate $PATH. Make more like advanced 'type's as well.
9166 *) The IRIXN32 Rule was being ignored. Configure now correctly adds
9167 -n32 only if IRIXN32 says to. [Jim Jagielski, Alain St-Denis
9168 <alain.st-denis ec.gc.ca>] PR#2736
9170 *) Clean up a warning in mod_proxy. [Ralf S. Engelschall]
9172 *) Renamed __EMX__ (internal define of the gcc port under OS/2) to OS2
9173 following the same idea as "MSVC vs WIN32". Additionally the src/os/emx/
9174 directory was renamed to src/os/os2/ for consistency.
9175 [Brian Havard, Ralf S. Engelschall]
9177 *) Add new Rule SHARED_CHAIN which can be used to enable linking of DSO
9178 files (here modules) against other DSO files (here shared libraries).
9179 This is done by determining a subset of LIBS which can be safely used for
9180 linking the DSOs, i.e. PIC libs and shared libs. Currently the rule is
9181 disabled for all platforms to avoid problems with this (experimental)
9182 rule. But we provide it now for those people how ran into problems and
9183 want to came out by forcing linking against DSOs.
9184 [Ralf S. Engelschall] PR#2587
9186 *) Fix suEXEC start message: Has to be of `notice' level to really get
9187 printed together with the standard startup message because the `notice'
9188 level is handled special inside ap_log_error() for startup messages.

9198 handling loop so that the connection can be properly closed with
9199 lingering_close, thus avoiding a potential TCP reset that would
9200 cause the client to miss the HTTP error response. [Roy Fielding]
9202 *) One more portability fix for APACI shadow tree support: Swap order of awk
9203 and sed in top-level configure script to avoid sed fails on some
9204 platforms (for instance SunOS 4.1.3 and NCR SysV) because of the
9205 non-newline-termined output of Awk. [Ralf S. Engelschall] PR#2729

9265 *) Add support for the Max-Forwards: header line required by RFC2068 for
9266 the TRACE method. This allows apache to TRACE along a chain of proxies
9267 up to a predetermined depth. [Martin Kraemer]
9269 *) Fix SHARED_CORE rule: The CFLAGS_SHLIB variable is no longer doubled

9310 party packages and to again reach consistency:

9318 *) mod_mmap_static will no longer take action on requests unless at
9319 least one "mmapfile" directive is present in the configuration.

9374 [John Van Essen <jve gamers.org>] PR#2529
9376 *) Add Dynamic Shared Object (DSO) support for SCO5 (OpenServer 5.0.x).
9377 [Ronald Record <rr sco.com>] PR#2533
9379 *) The APACI libexecdir was not extended with an "apache/" subdir
9380 if the installation prefix didn't already contain "apache", but
9381 it should be because the DSO files are Apache-specific. Now
9382 libexecdir is treated the same way sysconfdir, datadir, localstatedir
9383 and includedir are already treated.
9384 [Charles Levert <charles comm.polymtl.ca>] PR#2551
9386 *) The <Limit> parsing routine was incorrectly treating methods as
9387 case-insensitive. [Ken Coar]
9389 *) The ap_bprintf() code neglected to test if there was an error on
9390 the connection. ap_bflush() misdiagnosed a failure as a success.
9393 *) add support for #perl arg interpolation in mod_include
9396 *) API: Name changes of table_elts to ap_table_elts, is_table_empty
9397 to ap_is_table_empty and bgetflag to ap_bgetflag. [Ben Laurie]

9400 [Vadim Kostoglodoff <vadim olly.ru>] PR#2463
9402 *) Fix the Guess-DSO-flags-from-Perl stuff in src/Configure: "perl" was
9403 used instead of "$PERL" which contains the correctly determined Perl
9404 interpreter (important for instance on systems where "perl" and "perl5"
9405 exists, like BSDI or FreeBSD, etc).
9406 [Ralf S. Engelschall] PR#2505
9408 *) Move the initial suEXEC-related startup message from plain
9409 fprintf()/stderr to a delayed ap_log_error()-based one to avoid problems
9410 when Apache is started from inetd (instead of standalone). Under this
9411 situation startup messages on stderr lead to problems (the line is sent
9412 to the client in front of the requested document).

9419 [Ben Laurie, Bill Stoddard <wgstodda us.ibm.com>] PR#2274
9421 *) WIN32 SECURITY: Eliminate trailing "."s in path components. These are
9422 ignored by the Windows filesystem, and so can be used to bypass security.
9423 [Ben Laurie, Alexei Kosut].
9425 *) We now attempt to dump core when we get SIGILL. [Jim Jagielski]
9427 *) PORT: remove broken test for MAP_FILE in http_main.c.
9428 [Wilfredo Sanchez <wsanchez apple.com>]
9430 *) PORT: Change support/apachectl to use "kill -0 $pid" to test if the
9431 httpd is running. This should be more portable than figuring out
9432 which of three dozen different versions of "ps" are installed.
9435 *) WIN32: If we can't figure out how to execute a file in a script
9436 directory, bail out of the request with an error message. [W G Stoddard]
9438 *) WIN32 SECURITY: Eliminate directories consisting of three or more dots;
9439 these are treated by Win32 as if they are ".." but are not detected by
9440 other machinery within Apache. This is something of a kludge but
9441 eliminates a security hole. [Manoj Kasichainula, Ben Laurie]
9443 *) Move ap_escape_quotes() from src/ap to src/main/util.c; it uses
9444 pools and thus pollutes libap (until the pool stuff is moved there).
9447 *) IndexIgnore should be case-blind on Win32 (and any other case-aware
9448 but case-insensitive platforms). New #define for this added to conf.h
9449 (CASE_BLIND_FILESYSTEM). [Ken Coar] PR#2455
9451 *) Enable DSO support for OpenBSD in general, not only for 2.x, because it
9452 also works for OpenBSD 1.x. [Ralf S. Engelschall]
9454 *) PORT: Fix compilation problem on ARM Linux.
9455 [Sam Kington <sam illuminated.co.uk>] PR#2443
9457 *) Let APACI's configure script determine some configuration parameters
9458 (Group, Port, ServerAdmin, ServerName) via some intelligent tests to
9459 remove some of the classical hurdles for new users when setting up
9460 Apache. This is done per default because it is useful for the average
9461 user. Package authors can use the --without-confadjust option to disable
9462 these configuration adjustments.
9463 [Ralf S. Engelschall]
9465 *) Added an EXTRA_DEPS configuration parameter which can be used
9466 to add an extra Makefile dependency for the httpd target, for instance
9467 to external third-party libraries, etc.
9468 [Ralf S. Engelschall]
9470 *) Add <IfDefine>..</IfDefine> sections to the core module (with same spirit
9471 as <IfModule>..</IfModule> sections) which can be used to skip or process
9472 contained commands dependend of ``-D PARAMETER'' options on the command
9473 line. This can be used to achieve logical conditions like <IfDefine
9474 ReverseProxy> instead of physically ones (e.g. <IfModule mod_proxy.c>)
9475 and thus especially can be used for conditionally loading DSO-based
9476 modules via LoadModule, etc. [Ralf S. Engelschall]
9478 *) PORT: clean up a warning in mod_status for OS/2. [Brian Havard]
9480 *) Make table elements const. This may prevent obscure errors. [Ben Laurie]
9482 *) Fix parsing of FTP `SIZE' responses in proxy module: The newline was not
9483 truncated which forced following HTTP headers to be data in the HTTP
9484 reponse. [Ralf S. Engelschall, Charles Fu <ccwf bacchus.com>]
9487 *) Portability fix for APACI shadow tree support: Swap order of awk and sed
9488 in top-level configure script to avoid sed fails on some platforms (for
9489 instance SunOS 4.1.3 and NCR SysV) because of the non-newline-termined
9490 output of Awk. [Bill Houle <bhoule sandiegoca.ncr.com>] PR#2435
9492 *) Improve performance of directory listings (mod_autoindex) by comparing
9493 integer keys (last-modified and size) as integers rather than converting
9494 them to strings first. Also use a set of explicit byte tests rather
9495 than strcmp() to check for parent directory-ness of an entry. Oh, and
9496 make sure the parent directory (if displayed) is *always* listed first
9497 regardless of the sort key. Overall performance winnage should be good
9498 in CPU time, instruction cache, and memory usage, particularly for large
9499 directories. [Ken Coar]
9501 *) Add a tiny but useful goody to APACI's configure script: The generation
9502 of a config.status script (as GNU Autoconf does) which remembers the used
9503 configure command and hence can be used to restore the configuration by
9504 just re-running this script or for remembering the configuration between
9506 [Ralf S. Engelschall]
9508 *) Add httpd -t (test) option for running configuration syntax tests only.
9509 If something is broken it complains and exits with a return code
9510 non-equal to 0. This can be used manually by the user to check the Apache
9511 configuration after editing and is also automatically used by apachectl
9512 on (graceful) restart command to make sure Apache doesn't die on restarts
9513 because of a configuration which is now broken since the last (re)start.
9514 This way `apachectl restart' can be used inside cronjobs without having
9515 to expect Apache to be falling down. Additionally the httpd -t can be run
9516 via `apachectl configtest'.

9654 ap_spawn_child_err became ap_spawn_child
9655 ap_spawn_child_err_buff became ap_bspawn_child
9656 spawn_child was obsoleted and moved to compat.h
9659 *) Upgrade the child spawning code in mod_rewrite for the RewriteMap
9660 programs: ap_spawn_child_err() is used and the Win32 case now uses
9661 CreateProcess() instead of a low-level execl() (which caused problems in
9662 the past under Win32).
9663 [Ralf S. Engelschall]
9665 *) A few cosmetics and trivial enhancements to APXS to make the
9666 generated Makefile more user friendly. [Ralf S. Engelschall]
9668 *) Proxy Fix: The proxy special failure routine ap_proxyerror()
9669 was updated to use the normal apache error processing, thereby allowing
9670 proxy errors to be treated by ErrorDocument's as well. For this
9671 purpose, a new module-to-core communication variable "error-notes"
9672 was introduced; the proxy (and possibly other modules) communicates
9673 its error text using this variable. Its content is copied to a new
9674 cgi-env-var REDIRECT_ERROR_NOTES for use by ErrorDocuments.
9675 The old proxy special error routine ap_proxy_log_uerror()
9676 was replaced by regular ap_log_error() calls, many messages were made
9678 [Martin Kraemer] PR#494, 1259
9680 *) SECURITY: A possible buffer overflow in the ftp proxy was fixed.
9683 *) Transform the configure message "You need root privileges for suEXEC"
9684 from a fatal error into a (more friendly) warning because the building
9685 ("make") of Apache we can allow, of course. Root privileges are needed
9686 only for the installation step ("make install"). So make sure the
9687 user is aware of this fact but let him proceed as long as he can.
9688 [Ralf S. Engelschall] PR#2288
9690 *) Renamed three more functions to common ap_ prefix which we missed at the
9691 Big Symbol Renaming because they're #defines and not real C functions:
9692 is_default_port(), default_port(), http_method().
9693 [Ralf S. Engelschall]
9695 *) A zero-length name after a $ in an SSI document should cause
9696 just the $ to be in the expansion. This was broken during the

9709 substitution takes place, for instance via the following rule:
9710 ``RewriteRule ^myscript$ - [T=application/x-httpd-cgi]'' This was often

9712 extension and outside any cgi-bin dirs to be executed as a CGI program.

9715 *) A fix for protocol issues surrounding 400, 408, and

9722 [Rick Ohnemus <rick ecompcon.com>]
9724 *) Make mod_rewrite use ap_open_piped_log() for RewriteLog directive's
9725 logfile instead of fiddling around itself with child spawning stuff.

9728 *) Made RefererIgnore case-insensitive.
9730 *) Mod_log_agent, mod_log_referer now use ap_open_piped_log for piped logs.

9734 "safe" under Win32. In: mod_include.c, mod_mime_magic.c

9744 [Ben Laurie] PR#2238
9746 *) WIN32: CGIs could cause a hang (because of a deadlock in the standard C
9747 library), so CGI handling has been changed to use Win32 native handles
9748 instead of C file descriptors.
9749 [Ben Laurie and Bill Stoddard <wgstodda us.ibm.com>] PR#1129, 1607
9751 *) The proxy cache would store an incorrect content-length in the cached
9752 file copy after a cache update. That resulted in repeated fetching
9753 of the original copy instead of using the cached copy.
9754 [Ernst Kloppenburg <kloppen isr.uni-stuttgart.de>] PR#2094
9756 *) The Makefiles assumed that DSO files are build via $(LD). This
9757 is broken for two reasons: First we never defined at least LD=ld
9758 somewhere to make sure this works (it was silently assumed that most Make
9759 provide a built-in LD definition - ARGL!) and second using the generic LD
9760 variable is not the truth. Instead a special variable named LD_SHLIB is
9761 reasonable because although "ld" is usually the default, the command for
9762 building DSO files can be "libtool" or even "cc" on some systems.
9763 [Ralf S. Engelschall]
9765 *) Replace the AddVersionPlatform directive with ServerTokens which
9766 provides for more control over the format of the Server:
9767 header line. SERVER_SUBVERSION is no longer supported;
9768 all module should use the ap_add_version_component()
9769 API function instead. [Jim Jagielski]
9771 *) Support for the NCR MP/RAS 3.0
9772 [John Withers <withers semi.kcsc.mwr.irs.gov>]
9774 *) The LDFLAGS_SHLIB_EXPORT variable of src/Configuration[.tmpl] was
9775 not retrieved in src/Configure and thus was not useable.
9776 [Ralf S. Engelschall]
9778 *) Various Makefile consistency cleanups:
9779 - make OSDIR also automatically be relative to src/ like INCDIR
9780 - SUBDIRS is now generated in src/Makefile only and not in
9781 Makefile.config because it is a local define for this location.
9782 - remove BROKEN_BPRINTF_FLAGS because is it no longer used inside
9783 any Makefile but make sure that at least the "-K inline" is kept in
9785 - update the "depend" targets in Makefile.tmpl files to use $(OSDIR), too.
9786 - updated the dependencies theirself
9787 - removed not existing SHLIB variable from "clean" targets
9788 - replaced SHLIB_OBJS/SHLIBS_OBJ consistently with OBJS_PIC because OBJS
9789 already exists and OBJS_PIC are also just plain objects and have not
9790 directly to do with "shared" things. The only difference is that they
9791 contain PIC. So OBJS_PIC is the more canonical name.
9792 - Updated the Makefile-dependency lines for OBJS_PIC
9793 - Removed the Makefile-dependency line in Configure to avoid double
9795 - replaced ugly xx-so.o/xx.so-o hack with a clean and consistent usage
9796 of xxx.lo as GNU libtool does with its PIC objects
9797 - reduce local complexity in modules Makefile.tmpl by moving the last
9798 existing target "depend" to the generation section in Configure, too.
9799 - removed the historical $(SPACER) which was used in the past together
9800 with BROKEN_BPRINTF_FLAGS to avoid zig-zags in the build process. This
9801 is no longer needed.
9802 - force the build and run of the gen_xxx programs under main/ as the
9803 first step before building the objects because it looks cleaner
9804 [Ralf S. Engelschall]
9806 *) WIN32: Make Win32 work again after the /dev/null DoS fix.
9809 *) WIN32: Check for buffer overflows in ap_os_canonical_filename.
9812 *) WIN32: Don't force ISAPI headers to finish with \n.
9813 [Jim Patterson <Jim.Patterson Cognos.COM>, Ben Laurie] PR#2060
9815 *) When opening "configuration" files (like httpd.conf, htaccess
9816 and htpasswd), Apache will not allow them to be non-/dev/null
9817 device files. This closes a DoS hole. At the same time,
9818 we use ap_pfopen to open these files to handle timeouts.
9819 [Jim Jagielski, Martin Kraemer]
9821 *) Apache will now log the reason its httpd children exit if they exit
9822 due to an unexpected signal. (It requires a new porting define,
9823 SYS_SIGLIST, which if defined should point to a list of text
9824 descriptions of the signals available. See PORTING.) [Dean Gaudet]
9826 *) WIN32: chdir() doesn't make sense in a multithreaded environment
9827 like WIN32. Before, Win32 CGI's could have had sporadic failures
9828 if a chdir call from one thread was made between another chdir call
9829 and a spawn in another thread. So, for now don't chdir for CGI scripts
9830 in WIN32. The current CGI "spec" is unclear as to whether it's
9831 necessary. Long-term fix is to either serialize the chdir/spawn combo
9832 or use WIN32 native calls to spawn a process. This temp fix was
9833 necessary to remove this as a showstopper for 1.3's release.
9836 *) Cleanup the suEXEC support in APACI and make it more safe:
9837 1. Add big fat hint in INSTALL about risks and to read the
9838 htdocs/manual/suexec.html document before using the suexec-related
9840 2. Make sure the user has at least provided one --suexec-xxxx option
9841 (specifies suEXEC parameters) in addition to --enable-suexec option.
9842 If only --enable-suexec is given APACI stops with a hint to INSTALL
9843 and htdocs/manual/suexec.html documents.
9844 3. Provide two additional --suexec-xxxx options to make the suEXEC
9845 configuration complete (especially for package maintainers who else
9846 had to patch the source tree) by providing ways to configure minimal
9847 UID/GID and safe PATH, too.
9848 [Ralf S. Engelschall]
9850 *) Cleanup of the `configure --shadow' process:
9851 - make sure the configure script creates its temporary files in the
9852 shadow tree to avoid conflicts with parallel configure runs
9853 - removed unnecessary option "-r" from "rm" call for Makefiles
9854 - make sure the configure scripts creates the shadow-wrapper Makefile
9855 only when no shadow trees already exists
9856 - make sure "make distclean" removes the shadow-wrapper Makefile but only
9857 when no more shadow trees exists
9858 - overhauled mkshadow.sh script: now its more IFS-safe and approx. twice
9859 as fast (in the past it needed 70sec, now it runs just 38sec)
9860 - make sure CVS does not complain about the created files
9861 Makefille.<gnutriple> and directories src.<gnutriple>
9862 [Ralf S. Engelschall]
9864 *) Added the ap_add_version_component() API routine and the
9865 AddVersionPlatform core directive. The first allows modules to
9866 declare themselves in the Server response header field value,
9867 augmenting the SERVER_SUBVERSION define in the Configuration file
9868 with run-time settings (more useful in a loadable-module environment).
9869 AddVersionPlatform inserts a comment such as "(UNIX)" or "(Win32)"
9870 into the server version string. [Ken Coar] PR#2056
9872 *) Minor stability tweaks to avoid core dumps in ap_snprintf.
9875 *) Emit the "Accept-Range" header for the default handler.
9876 [Brian Behlendorf] PR#1464
9878 *) Add a note to httpd.conf-dist that apache will on some systems fail
9879 to start when the Group # is set to a negative or large positive value.
9882 *) Make sure the module execution order is correct even when some modules
9883 are loaded under runtime (`LoadModule') via the DSO mechanism:
9884 1. The list of loaded modules is now a dynamically allocated one
9885 and not the original statically list from modules.c
9886 2. The loaded modules are now correctly setup by LoadModule for
9887 later use by the AddModule command.
9888 3. When the DSO mechanism for modules is used APACI's `install'
9889 target now enables all created `LoadModule' lines per default because
9890 this is both already expected by the user _and_ needed to avoid
9891 confusion with the next point and reduces the Makefile.tmpl complexity
9892 4. When the DSO mechanism for modules is used, APACI's `install'
9893 target now additionally makes sure the module list is reconstructed
9894 via a complete `ClearModuleList+AddModule...' entry.
9895 5. The support tool `apxs' now also makes sure an AddModule command
9896 is added in addition to the LoadModule command.
9897 6. The modules.c generation was extended to now contain two
9898 comments to make sure no one is confused by the confusing terminology
9899 of loading/linking (we use load=link+load & link=activate instead of
9900 the obvious load=activate & link=link :-( )
9901 This way now there is no longer a difference under execution time between
9902 statically and dynamically linked modules.

9918 *) Makes mod_rewrite, mod_log_config, mod_status and the ServerSignature
9919 feature compatible with 'UseCanonicalName off' by changing
9920 r->server->server_hostname to ap_get_server_name(). And I changed some
9921 functions which use r->server->port to use ap_get_server_port() instead,
9922 because if there's no Port directive in the config r->server->port is 0.
9925 *) get/set_module_config are trivial enough to be better off inline. Worth

9938 in unix. [Martin Kraemer]
9940 *) Ronald Tschalaer's Accept-Encoding patch - preserve the "x-" in
9941 the encoding type from the Accept-Encoding header (if it's there)

9973 Additionally the checks for finding the vendor DSO library were moved
9974 from mod_so.c to Configure because first it needs $PLAT etc. and second
9975 mod_so already uses an abstraction layer and does not fiddle with the
9976 vendor functions itself.

9979 *) PORT: Some optimization defines for NetBSD
9980 [Jaromir Dolecek <dolecek ics.muni.cz>] PR#2165
9982 *) PORT: Dynamic Shared Object (DSO) support for NetBSD.
9983 [Jaromir Dolecek <dolecek ics.muni.cz>, Ralf S. Engelschall] PR#2158
9985 *) Add Dynamic Shared Object (DSO) support for AIX (at least 4.2 but older
9986 AIX variants should work fine, too. Even AIX 3.x should work). This is
9987 accomplished by using the free DSO emulation code from Jens-Uwe Mager
9988 which we put into a os/unix/os-dso-aix.c file.
9989 [Ralf S. Engelschall]
9991 *) PORT: Fix compiler warnings under AIX >= 4.2 where the manual pages imply
9992 that we should use NET_SIZE_T == int but the include files force size_t.
9993 [Ralf S. Engelschall]
9995 *) Fix two bugs in select() handling in http_main.c.
9998 *) Suppress "error(0)" messages for ap_log_error() when the APLOG_NOERRNO
9999 is unset (as it is in situations like timeouts) where it is unclear
10000 whether errno is set or not. [Martin Kraemer]
10002 *) Just having APACI's localstatedir is too general and not enough for most
10003 of the systems. 1.3b6 again required manual APACI patches by package
10004 maintainers from Red Hat and FreeBSD because for their filesystem layout a
10005 little bit more flexibility in configuring the paths is needed. Hence we
10006 provide three additional configure options (--runtimedir, --logfiledir,
10007 --proxycachedir) which now can be used for more granular adjustments if
10008 --localstatedir is not enough to fit the particular needs. As a nice
10009 side-effect this reduces some subdir fiddling in configure+Makefile.tmpl.
10010 [Ralf S. Engelschall]
10012 *) Make the install root for "make install" in APACI's Makefile overrideable
10013 by package authors. This way we are even more friendly to package
10014 maintainers (especially Debian and Red Hat) who build for the real prefix
10015 via "configure --prefix=/<real>" but use a different local prefix via
10016 "make root=/tmp/apache install" for rolling the package without bristling
10017 the target location on their system.
10018 [Ralf S. Engelschall]
10020 *) Workaround sed limitations in APACI's configure script by now

10050 the loops. [Ralf S. Engelschall]
10052 *) Make sure that "make install" doesn't overwrite the `mime.types' and
10053 `magic' files from an existing Apache installation. Because people often
10054 customize these for own MIME and content types.

10100 ap_snprintf, and ap_psprintf). See include/ap.h for docs.
10103 *) Because /usr/local/apache is the default prefix the ``configure

10133 calls. [Ralf S. Engelschall]
10135 *) PORT: Updated UnixWare 2.0.x and 2.1.x entries for DSO support and made
10136 APACI Makefile.tmpl "install" target more robust for sensible UnixWare
10137 Make. [Ralf S. Engelschall]
10139 *) ++++ THE BIG SYMBOL RENAMING ++++
10140 To avoid symbol clashes with third-party code compiled into the server,
10141 we globally applied the prefix "ap_" to the following classes of
10143 - Apache provided general functions (e.g., ap_cpystrn)
10144 - Public API functions (e.g., palloc, bgets)
10145 - Private functions which we can't make static (because of
10146 cross-object usage) but should be (e.g., new_connection)
10147 For backward source compatibility a new header file named compat.h was
10148 created which provides defines for the old symbol names and can be used
10149 by third-party module authors.
10152 *) Added dynamic shared object (DSO) support for SVR4-derivates: The
10153 problem under SVR4 is that there is no command flag to force the linker
10154 to export the global symbols of the httpd executable therewith they are
10155 available to the DSO's. Instead of problematic hacks like creating a
10156 dummy.so file (containing dummy references to all global symbols) the
10157 httpd binary is linked against, we use a clean trick stolen from Perl 5:
10158 Placing the Apache core code itself into a DSO library named libhttpd.so.
10159 This way the global symbols _HAVE_ to be exported and thus are available
10160 to any manually loaded DSO's under runtime. To reduce the impact to the
10161 user to null we go even further and create a stub httpd executable which
10162 automatically keeps track of the DSO library loading itself and thus
10163 hides the complete mechanism from the user. Although the generation of
10164 this DSO library is automatically triggered for platforms which
10165 essentially need it (mostly all SVR4-derivates) it can be also enabled
10166 manually via the Rule SHARED_CORE. This can be interesting in the future
10167 where we perhaps exploit this libhttpd.so mechanism for providing nifty
10168 features like graceful upgrades, or whatever.
10169 [Ralf S. Engelschall, Martin Kraemer]
10171 *) Build the libraries before building the rest of the tools. [Ben Hyde]
10173 *) Add "distclean" target to src/-Makefiles to provide "make distclean" also
10174 inside the src subtree (i.e. for non-APACI users). Following GNU Makefile
10175 conventions while "clean" removes only stuff created by "all" targets,
10176 "distclean" additionally removes the stuff from the configuration
10177 process. This way "make distclean" (hence the name) provides a fresh
10178 source tree as it was for distribution.
10179 [Ralf S. Engelschall]
10181 *) Allow top-level (APACI) Makefile to break on build errors
10182 the same way the src/ subtree Makefiles breaks on them by replacing the
10183 initial APACI sed-subdir-display-kludge with a more clean
10184 variable-passing-solution: variable SDP can optionally hold the subdir
10185 prefix which is consistently used for displaying the subdir movement.
10186 This way even the top-level Makefile can stop correctly on errors as the
10187 user expects. [Ralf S. Engelschall]
10189 *) Fixed ordering of argument checks for RewriteBase directive.
10190 [Todd Eigenschink <eigenstr mixi.net>] PR#2045
10192 *) Change Win32 IS_MODULE to SHARED_MODULE to match Unix' method of

10194 remove #define IS_MODULE from modules and add SHARED_MODULE define
10195 to the mak/dsp files. [Alexei Kosut]
10197 *) Reduce logging level of "normal" warning messages to APLOG_INFO,
10198 since we are now logging APLOG_WARNING by default. [Roy Fielding]
10200 *) PORT: OS/2 tweak to deal with multiple .exe targets. [Brian Havard]
10202 *) Add documentation file and src/Configuration.tmpl entry for the
10203 experimental mod_mmap_static module. Because although it is and marked as
10204 an experimental one it is distributed and thus should be documented and
10205 prepared for configuration the same way as all others modules.
10206 [Ralf S. Engelschall]
10208 *) Add query (-q) option to apxs support tool to be able to manually query
10209 specific settings from apxs. This is needed for instance when you
10210 manually want to access Apache's header files and you need to assemble
10211 the -I option. Now you can do -I`apxs -q INCLUDEDIR`.
10212 [Ralf S. Engelschall]
10214 *) Now src/Configure uses a fallback strategy for the shared object support
10215 on platforms where no explicit information is available: If a Perl
10216 installation exists we ask it about its shared object support and if it's
10217 the dlopen-style one we shamelessly guess the compiler and linker flags
10218 for creating shared objects from Perls knowledge. Of course, the user is
10219 warning about what we are doing and informed that he should send us
10220 the guessed flags when they work. [Ralf S. Engelschall]
10222 *) Provide APACI --without-support option to be able to disable the build
10223 and installation of the support tools from the src/support/ area.
10224 Although its useful to have these installed per default we should provide
10225 a way to compile and install without them for backward-compatibility.
10226 [Ralf S. Engelschall]
10228 *) Add of the new APache eXtenSion (apxs) support tool for building and
10229 installing modules into an _already installed_ Apache package through the
10230 dynamic shared object (DSO) mechanism [mod_so.c]. The trick here is that
10231 this approach actually doesn't need the Apache source tree. The
10232 (APACI-installed) server package is enough, because this now includes the
10233 Apache C header files (PREFIX/include) and the new APXS tool
10234 (SBINDIR/apxs). The intend is to provide a handy tool for third-party
10235 module authors to build their Apache modules _OUTSIDE_ the Apache source
10236 tree while avoiding them to fiddle around with the totally platform
10237 dependend way of compiling DSO files. The tool supports all ranges of
10238 modules, from trivial ones (single mod_foo.c) to complex ones (like PHP3
10239 which has a mod_php3.c plus a pre-built libmodphp3-so.a) and even can
10240 on-the-fly generate a minimalistic Makefile and sample module for the
10241 first step to provide both a quick success event and to demonstrate the
10242 APXS mechanism to module authors. [Ralf S. Engelschall]
10244 *) Fix core dumps in use of CONNECT in proxy.

10247 *) Modify the log directives in httpd.conf-dist files to use CustomLog
10248 so that users have examples of how CustomLog can be used.
10251 *) Add the new Apache Autoconf-style Interface (APACI) for the top-level of
10252 the Apache distribution tree. Until Apache 1.3 there was no real
10253 out-of-the-box batch-capable build and installation procedure for the
10254 complete Apache package. This is now provided by a top-level "configure"
10255 script and a corresponding top-level "Makefile.tmpl" file. The goal is
10256 to provide a GNU Autoconf-style frontend which is capable to both drive
10257 the old src/Configure stuff in batch and additionally installs the
10258 package with a GNU-conforming directory layout. Any options from the old
10259 configuration scheme are available plus a lot of new options for flexibly
10260 customizing Apache. [Ralf S. Engelschall]
10262 *) The floating point ap_snprintf code wasn't threadsafe.

10274 *) "Options +Includes" wasn't correctly merged if "+IncludesNoExec"
10275 was defined in a parent directory. [Lars Eilebrecht]
10277 *) API: ap_snprintf() code mutated into ap_vformatter(), which is
10278 a generic printf-style routine that can call arbitrary output
10279 routines. Use this to replace http_bprintf.c. Add new routines
10280 psprintf(), pvsprintf() which allocate the exact amount of memory
10281 required for a string from a pool. Use psprintf() to clean up
10282 various bits of code which used ap_snprintf()/pstrdup().
10285 *) PORT: HAVE_SNPRINTF doesn't do anything any longer. This is because
10286 ap_snprintf() has different semantics and formatting codes than
10287 snprintf(). [Dean Gaudet]
10289 *) SIGXCPU and SIGXFSZ are now reset to SIG_DFL at boot-time. This
10290 is necessary on at least Solaris where the /etc/rc?.d scripts

10323 Without this, the proxy would fail to work for any URL's with

10338 *) Now mod_proxy uses the response string (in addition to the response status
10339 code) from the already used FTP SIZE command to setup the Content-Length
10340 header if available. [Ralf S. Engelschall] PR#1183
10342 *) Reanimated the (still undocumented) proxy receive buffer size directive:
10343 Renamed from ReceiveBufferSize to ProxyReceiveBufferSize because the old
10344 name was really too generic, added documentation for this directive to
10345 the mod_proxy.html and corrected the hyperlink to it in the
10346 new_features_1.3.html document. [Ralf S. Engelschall] PR#1348
10348 *) Fix a bug in the src/helpers/fp2rp script and make it a little bit
10349 faster [Martin Kraemer]
10351 *) Make Configure die when you give it an unknown command switch.
10354 *) Add five new and fresh manpages for the support programs: dbmmanage.1,
10355 suexec.8, htdigest.1, rotatelogs.8 and logresolve.8. Now all up-to-date
10356 and per default compiled support programs have manual pages - just to
10357 document our stuff a little bit more and to be able to do really
10358 Unix-like installations ;-) [Ralf S. Engelschall]
10360 *) Major cleanups to the Configure script to make it and its generated
10361 Makefiles again readable and maintainable: add SRCDIR option, removed
10362 INCLUDES_DEPTH[0-2] kludge, cleanup of TARGET option, cleanup of
10363 generated sections, consequently added Makefile headers with inheritance
10364 information, added subdir movement messages for easier following where
10365 the build process currently stays (more verbose then standard Make, less
10366 verbose than GNU make), same style to comments in the Configure script,
10367 added Apache license header, fixed a few bugs, etc. [Ralf S. Engelschall]
10369 *) Add the new ApacheBench program "ab" to src/support/: This is derived
10370 from the ZeusBench benchmarking program and can be used to determine the
10371 response performance of an Apache installation. This version is
10372 officially licensed with Zeus Technology, Ltd. See the license agreement

10374 [Ralf S. Engelschall]
10376 *) API: Various core functions that are definately not part of the API
10377 have been made static, and a few have been marked API_EXPORT. Still
10378 more have been marked CORE_EXPORT and are not intended for general
10379 use by modules. [Doug MacEachern, Dean Gaudet]
10381 *) mod_proxy was not clearing the Proxy-Connection header from
10382 requests; now it does. This did not violate any spec, however
10383 causes poor interactions when you are talking to remote proxies.

10392 *) Performance tweak to mod_log_config. [Dmitry Khrustalev]
10394 *) Clean up some undocumented behavior of mod_setenvif related to
10395 "merging" two SetEnvIf directives when they match the same header
10396 and regex. Document that mod_setenvif will perform comparisons in
10397 the order they appear in the config file. Optimize mod_setenvif by
10398 doing more work at config time rather than at runtime.
10401 *) src/include/ap_config.h now wraps it's #define's with #ifndef/#endif's
10402 to allow for modules to overrule them and to reduce redefinition
10403 warnings [Jim Jagielski]
10405 *) [PORT] For A/UX change the OS-#define for -DAUX to -DAUX3.
10408 *) Making the hard-coded cross-module function call mime_find_ct() (from
10409 mod_proxy to mod_mime) obsolete by making sure the API hook for MIME type
10410 checking is really called even for proxy requests except for URLs with
10411 HTTP schemes (because there we can optimize by not running the type
10412 checking hooks due to the fact that the proxy gets the MIME Content-type
10413 from the remote host later). This change cleans up mod_mime by removing
10414 the ugly export kludge, makes the one-liner file mod_mime.h obsolete, and
10415 especially unbundles mod_proxy and mod_mime. This way they both now can
10416 be compiled as shared objects and are no longer tied together.
10417 [Ralf S. Engelschall]
10419 *) util.c cleanup and speedup. [Dean Gaudet]
10421 *) API: Clarification, pstrndup() will always copy n bytes of the source
10422 and NUL terminate at the (n+1)st byte. [Dean Gaudet]
10424 *) Mark module command_rec and handler_rec structures const so that they
10425 end up in the read-only data section (and are friendlier to systems
10426 that don't do optimistic memory allocation on fork()). [Dean Gaudet]
10428 *) Add check to the "Port" directive to make sure the specified
10429 port is in the appropriate range. [Ben Hyde]
10431 *) Performance improvements to invoke_handler().
10432 [Dmitry Khrustalev <dima bog.msu.su>]
10434 *) Added support for building shared objects even for library-style modules
10435 (which are built from more than one object file). This now provides the
10436 ability to build mod_proxy as a shared object module. Additionally
10437 modules like mod_example are now also supported for shared object
10438 building because the generated Makefiles now no longer assume there is at
10439 least one statically linked module. [Ralf S. Engelschall]
10441 *) API: Clarify usage of content_type, handler, content_encoding,
10442 content_language and content_languages fields in request_rec. They
10443 must always be lowercased; and the strings pointed to shouldn't
10444 be modified (you must copy them to modify them). Fix a few bugs
10445 related to this. [Dean Gaudet]
10447 *) API: Clarification: except for RAW_ARGS, all command handlers can
10448 treat the char * parameters as permanent, and modifiable. There
10449 is no need to pstrdup() them. Clean up some needless pstrdup().
10452 *) Now mod_so keeps track of which module shared objects with which names
10453 are loaded and thus avoids multiple loading and unloading and irritating
10454 error_log messages. [Ralf S. Engelschall]
10456 *) Prior to the existence of mod_setenv it was necessary to tweak the TZ
10457 environment variable in the apache core. But that tweaking interferes
10458 with mod_setenv. So don't tweak if the user has specified an explicit
10459 TZ variable. [Jay Soffian <jay cimedia.com>] PR#1888
10461 *) rputs() did not calculate r->sent_bodyct properly.
10462 [Siegmund Stirnweiss <siegst kat.ina.de>] PR#1900
10464 *) The CGI spec says that REMOTE_HOST should be set to the remote hosts's
10465 name, or left unset if this value is unavailable. Apache was setting
10466 it to the IP address when unavailable.
10467 [Tony Finch <fanf demon.net>] PR#1925
10469 *) Various improvements to the configuration and build support for compiling
10470 modules as shared objects. Especially Solaris 2.x, SunOS 4.1, IRIX and
10471 OSF1 support with GCC and vendor compilers was added. This way shared
10472 object support is now provided out-of-the-box for FreeBSD, Linux,
10473 Solaris, SunOS, IRIX and OSF1. In short: On all major platforms!
10474 [Ralf S. Engelschall]
10476 *) Minor cleanup in http_main -- split QNX and OS2 specific "mmap"
10477 scoreboard code into separate #defines -- USE_POSIX_SCOREBOARD
10478 and USE_OS2_SCOREBOARD. [Dean Gaudet]
10480 *) Fix one more special locking problem for RewriteMap programs in
10481 mod_rewrite: According to the documentation of flock(), "Locks are on
10482 files, not file descriptors. That is, file descriptors duplicated
10483 through dup(2) or fork(2) do not result in multiple instances of a lock,
10484 but rather multiple references to a single lock. If a process holding a
10485 lock on a file forks and the child explicitly unlocks the file, the
10486 parent will lose its lock.". To overcome this we have to make sure the
10487 RewriteLock file is opened _AFTER_ the childs were spawned which is now
10488 the case by opening it in the child_init instead of the module_init API
10489 hook. [Ralf S. Engelschall] PR#1029
10491 *) Change to Location and LocationMatch semantics. LocationMatch no
10492 longer lets a single slash match multiple adjacent slashes in the
10493 URL. This change is for consistency with RewriteRule and
10494 AliasMatch. Multiple slashes have meaning in URLs that they do
10495 not have in (some) filesystems. Location on the other hand can
10496 be considered a shorthand for a more complicated regex, and it
10497 does match multiple slashes with a single slash -- which is
10498 also consistent with the Alias directive.
10499 [Dean Gaudet] related PR#1440
10501 *) Fix bug with mod_mime_magic causing certain files, including files
10502 of length 0, to result in no response from the server.
10505 *) The Configure script now generates src/include/ap_config.h which
10506 contains the set of defines used when Apache is compiled on a platform.
10507 This file can then be included by external modules before including
10508 any Apache header files in case they are being built separately from
10509 Apache. Along with this change, a couple of minor changes were
10510 made to make Apache's #defines coexist peacefully with any autoconf
10511 defines an external module might have. [Rasmus Lerdorf]
10513 *) Fix mod_rewrite for the ugly API case where <VirtualHost> sections exist
10514 but without any RewriteXXXXX directives. Here mod_rewrite is given no
10515 chance by the API to initialize its per-server configuration and thus
10516 receives the wrong one from the main server. This is now avoided by
10517 remembering the server together with the config structure while
10518 configuring and later assuming there is no config when we see a
10519 difference between the remembered server and the one calling us.
10520 [Ralf S. Engelschall] PR#1790
10522 *) Fixed the DBM RewriteMap support for mod_rewrite: First the support now
10523 is automatically disabled under configure time when the dbm_xxx functions
10524 are not available. Second, two heavy source code errors in the DBM
10525 support code were fixed. This makes DBM RewriteMap's usable again after
10526 a long time of brokenness. [Ralf S. Engelschall] PR#1696
10528 *) Now all configuration files support Unix-style line-continuation via
10529 the trailing backslash ("\") character. This enables us to write down
10530 complex or just very long directives in a more readable way. The
10531 backslash character has to be really the last character before the
10532 newline and it has not been prefixed by another (escaping) backslash.

10538 *) To deal with modules being compiled and [dynamically] linked
10539 at a different time from the core, the SERVER_VERSION and
10540 SERVER_BUILT symbols have been abstracted through the new
10541 API routines apapi_get_server_version() and apapi_get_server_built().
10544 *) WIN32: Preserve trailing slash in canonical path (and hence
10545 in PATH_INFO). [Paul Sutton, Ben Laurie]
10547 *) PORT: USE_PTHREAD_SERIALIZED_ACCEPT has proven unreliable
10548 depending on the rev of Solaris and what mixture of modules
10549 are in use. So it has been disabled, and Solaris is back to
10550 using USE_FCNTL_SERIALIZED_ACCEPT. Users may experiment with
10551 USE_PTHREAD_SERIALIZED_ACCEPT at their own risk, it may speed
10552 up static content only servers. Or it may fail unpredictably.

10555 *) mod_test_util_uri.c created which tests the logic in util_uri.c.
10558 *) API: Rewrite of absoluteURI handling, and in particular how
10559 absoluteURIs match vhosts. Unless a request is a proxy request, a
10560 "http://host" url is treated as if a similar "Host:" header had been
10561 supplied. This change was made to support future HTTP/1.x protocols
10562 which may require clients to send absoluteURIs for all requests.
10564 In order to achieve this change subtle changes were made to the API. In a
10565 request_rec, r->hostlen has been removed. r->unparsed_uri now exists so
10566 that the unmodified uri can be retrieved easily. r->proxyreq is not set
10567 by the core, modules must set it during the post_read_request or
10568 translate_names phase.
10570 Plus changes to the virtualhost test suite for absoluteURI testing.
10572 This fixes several bugs with the proxy proxying requests to vhosts
10573 managed by the same httpd.
10576 *) API: Cleanup of code in http_vhost.c, and remove vhost matching
10577 code from mod_rewrite. The vhost matching is now performed by a
10578 globally available function matches_request_vhost(). [Dean Gaudet]

10594 *) API: A new source module main/util_uri.c; It contains a routine
10595 parse_uri_components() and friends which breaks a URI into its component
10596 parts. These parts are stored in a uri_components structure called
10597 parsed_uri within each request_rec, and are available to all modules.
10598 Additionally, an unparse routine is supplied which re-assembles the URI
10599 components back to an URI, optionally hiding the username:password@ part
10600 from ftp proxy requests, and other useful routines. Within the structure,
10601 you find on a ready-for-use basis:
10602 scheme; /* scheme ("http"/"ftp"/...) */
10603 hostinfo; /* combined [user[:password]@]host[:port] */
10604 user; /* user name, as in http://user:passwd@host:port/ */
10605 password; /* password, as in http://user:passwd@host:port/ */
10606 hostname; /* hostname from URI (or from Host: header) */
10607 port_str; /* port string (integer representation is in "port") */
10608 path; /* the request path (or "/" if only scheme://host was given) */
10609 query; /* Everything after a '?' in the path, if present */
10610 fragment; /* Trailing "#fragment" string, if present */
10611 This is meant to serve as the platform for *BIG* savings in
10612 code complexity for the proxy module (and maybe the vhost logic).
10615 *) Make all possible meta-construct expansions ($N, %N, %{NAME} and
10616 ${map:key}) available for all location where a string is created in
10617 mod_rewrite rewriting rulesets: 1st arg of RewriteCond, 2nd arg of
10618 RewriteRule and for the [E=NAME:STRING] flag of RewriteRule. This way the
10619 possible expansions are consequently usable at all string creation
10620 locations. [Ralf S. Engelschall]
10622 *) Fix initialization of RewriteLogLevel (default now is 0 as documented
10623 and not 1) and the per-virtual-server merging of directives. Now all
10624 directives except `RewriteEngine' and `RewriteOption' are either
10625 completely overridden (default) or completely inherited (when
10626 `RewriteOptions inherit') is used. [Ralf S. Engelschall] PR#1325

10635 *) Fix long-standing problem with RewriteMap _programs_ under Unix derivates
10636 (like SunOS and FreeBSD) which don't accept the locking of pipes
10637 directly. A new directive RewriteLock is introduced which can be used to
10638 setup a separate locking file which then is used for synchronization.

10656 *) Add new RewriteMap types: First, `rnd' which is equivalent to the `txt'
10657 type but with a special post-processing for the looked-up value: It
10658 parses it into alternatives according to `|' chars and then only one
10659 particular alternative is chosen randomly (this is an essential
10660 functionality needed for balancing between backend-servers when using
10661 Apache as a Reverse Proxy. The looked up value here is a list of
10662 servers). Second, `int' with the built-in maps named `tolower' and
10663 `toupper' which can be used to map URL parts to a fixed case (this is an
10664 essential feature to fix the case of server names when doing mass
10665 virtual-hosting with the help of mod_rewrite instead of using
10666 <VirtualHost> sections). [Ralf S. Engelschall, parts based on code from

10669 *) Add a new directive to mod_proxy similar to ProxyPass: `ProxyPassReverse'.
10670 This directive lets Apache adjust the URL in Location-headers on HTTP
10671 redirect responses sent by the remote server. This way the virtually
10672 mapped area is no longer left on redirects and thus by-passed which is

10811 *) There are many cases where users do not want Apache to form
10812 self-referential urls using the "canonical" ServerName and Port.
10813 The new UseCanonicalName directive (default on), if set to off
10814 will cause Apache to use the client-supplied hostname and port.
10815 API: Part of this change required a change to the construct_url()

10821 *) Yet another rearrangement of the source tree.. now all the common
10822 header files are in the src/include directory. The -Imain -Iap
10823 references in Makefiles have been changed to the simpler -Iinclude
10824 instead. In addition to simplifying the build a little bit, this
10825 also makes it clear when a module is referencing something in a
10826 other than kosher manner (e.g., the proxy including mod_mime.h).
10827 Module-private header files (the proxy, mod_mime, the regex library,
10828 and mod_rewrite) have not been moved to src/include; nor have
10829 the OS-abstraction files. [Ken Coar]
10831 *) Fix a bug where r->hostname didn't have the :port stripped
10832 from it. [Dean Gaudet]
10834 *) Tweaked the headers_out table size, and the subprocess_env
10835 table size guess in rename_original_environment(). Added
10836 MAKE_TABLE_PROFILE which can help discover make_table()
10837 calls that use too small an initial guess, see alloc.c.
10840 *) Options and AllowOverride weren't properly merging in the main
10841 server setting inside vhosts (only an issue when you have no
10842 <Directory> or other section containing an Options that affects
10843 a request). Options +foo or -foo in the main_server wouldn't
10844 affect the main_server's lookup defaults. [Dean Gaudet]
10846 *) Variable 'cwd' was being used pointlessly before being set.
10849 *) r->allowed handling cleaned up in the standard modules.

10856 [Mark Andrew Heinrich <heinrich tinderbox.Stanford.EDU>]
10858 *) mod_unique_id was erroneously generating a second unique id when
10859 an internal redirect occured. Such redirects occur, for example,
10860 when processing a DirectoryIndex match. [Dean Gaudet]
10862 *) API: table_add, table_merge, and table_set include implicit pstrdup()
10863 of the key and value. But in many cases this is not required
10864 because the key/value is a constant, or the value has been built
10865 by pstrcat() or other similar means. New routines table_addn,
10866 table_mergen, and table_setn have been added to the API, these
10867 routines do not pstrdup() their arguments. The core code and
10868 standard modules were changed to take advantage of these routines.
10869 The resulting server is up to 20% faster in some situations.
10871 Note that it is easy to get code subtly wrong if you pass a key/value
10872 which is in a pool other than the pool of the table. The only
10873 safe thing to do is to pass key/values which are in the pool of
10874 the table, or in one of the ancestors of the pool of the table.
10875 i.e. if the table is part of a subrequest, a value from the main
10876 request's pool is OK since the subrequest pool is a sub_pool of the
10877 main request's pool (and therefore has a lifespan at most as long as
10878 the main pool). There is debugging code which can detect improper
10879 usage, enabled by defining POOL_DEBUG. See alloc.c for more details.

10895 *) API: "typedef array_header table" removed from alloc.h, folks should
10896 have been writing to use table as if it were an opaque type, but even
10897 some standard modules got this wrong. By changing the definition
10898 to "typedef struct table table" module authors will receive compile
10899 time warnings that they're doing the wrong thing. This change
10900 facilitates future changes with more sophisticated table
10901 structures. Specifically, module authors should be using table_elts()
10902 to get access to an array_header * for the table. [Dean Gaudet]

10905 library routines. [Ken Coar, Rasmus Lerdorf]
10907 *) WIN32: mod_speling is now available on the Win32 platform.
10910 *) For clarity the following compile time definition was changed:
10912 SAFE_UNSERIALIZED_ACCEPT -> SINGLE_LISTEN_UNSERIALIZED_ACCEPT
10914 Also, for example, HAVE_MMAP would mean to use mmap() scoreboards
10915 and not be a general notice that the OS has mmap(). Now the
10916 HAVE_MMAP/SHMGET #defines strictly are informational that the
10917 OS has that method of shared memory; the type to use for
10918 the scoreboard is a seperate #define (USE_MMAP_SCOREBOARD
10919 and USE_SHMGET_SCOREBOARD). This allows outside modules to
10920 determine if shared memory is available and allows Apache
10921 to determine the best method to use for the scoreboard.

11422 Changes with Apache 1.3b2 (there is no 1.3b1)
11424 *) TestCompile was not passing $LIBS [Dean Gaudet]
11426 *) Makefile.tmpl was not using $CFLAGS in the link phase.
11429 *) Add debugging code to alloc.c. Defining ALLOC_DEBUG provides a
11430 rudimentary memory debugger which can be used on live servers with
11431 low impact -- it sets all allocated and freed memory bytes to 0xa5.
11432 Defining ALLOC_USE_MALLOC will cause the alloc code to use malloc()
11433 and free() for each object. This is far more expensive and should
11434 only be used for testing with tools such as Electric Fence and
11435 Purify. See main/alloc.c for more details. [Dean Gaudet]
11437 *) Configure uses a sh trap and didn't set its exitcode properly.
11438 [Dean Gaudet] PR#1159
11440 *) Yet another vhost revamp. Add the NameVirtualHost directive which
11441 explicitly lists the ip:port pairs that are to be used for name-vhosts.
11442 From a given ip:port, regardless what the Host: header is, you can
11443 only reach the vhosts defined on that ip:port. The precedence of
11444 vhosts was reversed to match other precedences in the config --
11445 the earlier vhosts override the later vhosts. All vhost matching was
11446 moved into http_vhost.[ch]. [Dean Gaudet]
11448 *) ap_inline can be used to force inlining. GNUC __attribute__() can
11449 be used for whatever reason is appropriate (i.e. format() warnings
11450 for printf style functions). Both are enabled only with
11451 gcc >= 2.7.x (so that we have fewer support issues with older
11452 versions). [Dean Gaudet]
11454 *) Fix support for Proxy Authentication (we were testing the response
11455 status too early). [Marc Slemko]
11457 *) CoreDumpDirectory directive directs where the core file is
11458 written when a SIGSEGV, SIGBUS, SIGABORT or SIGABRT are
11459 received. [Marc Slemko, Dean Gaudet]
11461 *) PORT: Support for Atari MINT.
11462 [Jan Paul Schmidt <Jan.P.Schmidt mni.fh-giessen.de>]
11464 *) When booting, apache will now detach itself from stdin, stdout,
11465 and stderr. stderr will not be detached until after the config
11466 files have been read so you will be able to see initial error
11467 messages. After that all errors are logged in the error_log.
11468 This makes it more convenient to start apache via rsh, ssh,
11469 or crontabs. [Dean Gaudet] PR#523
11471 *) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
11472 Also removed the auto-generated link to www.apache.org that was the
11473 source of so many misdirected bug reports. [Roy Fielding, Marc Slemko]
11475 *) send_fb would not detect aborted connections in some situations.
11478 *) mod_include would use uninitialized data when parsing certain
11479 expressions involving && and ||. [Brian Slesinsky] PR#1139
11481 *) mod_imap should only handle GET methods. [Jay Bloodworth]
11483 *) suexec.c wouldn't build without -DLOG_EXEC. [Jason A. Dour]
11485 *) mod_autoindex improperly counted &escapes; as more than one
11486 character in the description. It also improperly truncated
11487 descriptions that were exactly the maximum length.
11490 *) RedirectMatch was not properly escaping the result (PR#1155). Also
11491 "RedirectMatch /advertiser/(.*) $1" is now permitted.
11494 *) mod_include now uses symbolic names to check for request success
11495 and return HTTP errors, and correctly handles all types of
11496 redirections (previously it only did temporary redirect correctly).
11497 [Ken Coar, Roy Fielding]
11499 *) mod_userdir was modifying r->finfo in cases where it wasn't setting
11500 r->filename. Since those two are meant to be in sync with each other
11501 this is a bug. ["Paul B. Henson" <henson intranet.csupomona.edu>]
11503 *) PORT: Support Unisys SVR4, whose uname returns mostly useless data.
11504 ["Kaufman, Steven E" <Steven.Kaufman unisys.com>]
11506 *) Inetd mode (which is buggy) uses timeouts without having setup the
11507 jmpbuffer. [Dean Gaudet] PR#1064
11509 *) Work around problem under Linux where a child will start looping
11510 reporting a select error over and over.
11511 [Rick Franchuk <rickf transpect.net>] PR#1107, 987, 588
11513 *) Fixed error in proxy_util.c when looping through multiple host IP
11514 addresses. [Lars Eilebrecht] PR#974
11516 *) If BUFFERED_LOGS is defined then mod_log_config will do atomic
11517 buffered writes -- that is, it will buffer up to PIPE_BUF (i.e. 4k)
11518 bytes before writing, but it will never split a log entry across a
11519 buffer boundary. [Dean Gaudet]
11521 *) API: the short_score record has been split into two pieces, one which
11522 the parent writes on, and one which the child writes on. As part of
11523 this change the get_scoreboard_info() function was removed, and
11524 scoreboard_image was exported. This change fixes a race condition
11525 in file based scoreboard systems, and speeds up changes involving the
11526 scoreboard in earlier 1.3 development. [Dean Gaudet]
11528 *) API: New register_other_child() API (see http_main.h) which allows
11529 modules to register children with the parent for maintenance. It
11530 is disabled by defining NO_OTHER_CHILD. [Dean Gaudet]
11532 *) API: New piped_log API (see http_log.h) which implements piped logs,
11533 and will use register_other_child to implement reliable piped logs
11534 when it is available. The reliable piped logs part can be disabled
11535 by defining NO_RELIABLE_PIPED_LOGS. At the moment reliable piped
11536 logs is only available on Unix. [Dean Gaudet]
11538 *) API: set_last_modified() broken into set_last_modified(), set_etag(), and
11539 meets_conditions(). This allows conditional HTTP selection to be
11540 handled separately from the storing of the header fields, and provides
11541 the ability for CGIs to set their own ETags for conditional checking.
11542 [Ken Coar, Roy Fielding] PR#895
11544 *) Changes to mod_log_config to allow naming of format strings.
11545 Format nicknames are defined with "LogFormat fmt nickname", and can
11546 be used with "LogFormat nickname" and "CustomLog logtarget nickname".
11549 *) New module, "mod_speling", which can help find files even when
11550 the URL is slightly misspelled. [Martin Kraemer, Alexei Kosut]
11552 *) API: New function child_terminate() triggers the child process to
11553 exit, while allowing the child finish what it needs to for the
11554 current request first.
11555 [Doug MacEachern, Alexei Kosut]
11557 *) Windows now defaults to using full status reports with mod_status.
11558 [Alexei Kosut] PR #1094
11560 *) *Really* disable all mod_rewrite operations if the engine is off.
11561 Some things (like RewriteMaps) were checked/performed even if they
11562 weren't supposed to be. [Ken Coar] PR #991
11564 *) Implement a new timer scheme which eliminates the need to call alarm() all
11565 the time. Instead a counter in the scoreboard for each child is used to
11566 show when the child has made forward progress. The parent samples this
11567 counter every scoreboard maintenance cycle, and issues SIGALRM if no
11568 progress has been made in the timeout period. This reduces the static
11569 request best-case syscall count to 22 from 29. This scheme is only
11570 used by systems with memory-based scoreboards. [Dean Gaudet]
11572 *) The proxy now properly handles CONNECT requests which are sent
11573 to proxy servers when using ProxyRemote. [Marc Slemko] PR#1024
11575 *) A script called apachectl has been added to the support
11576 directory. This script allows you to do things such as
11577 "apachectl start" and "apachectl restart" from the command
11578 line. [Marc Slemko]
11580 *) Modules and core routines are now put into libraries, which
11581 simplifies the link line tremendously (among other advantages).
11584 *) Some of the MD5 names defined in Apache have been renamed to have
11585 an `ap_' prefix to avoid conflicts with routines supplied by
11586 external libraries. [Ken Coar]
11588 *) Removal of mod_auth_msql.c from the distribution. There are many
11589 other options for databases today. Rather than offer one option,
11590 offer none at this time. mod_auth_msql and other SQL database
11591 authentication modules can be found at the Apache Module Registry.
11592 http://modules.apache.org/ It would be nice to offer a generic
11593 mod_auth_sql option in the near future.
11595 *) PORT: BeOS support added [Alexei Kosut]
11597 *) Configure no longer accepts the -make option, since it creates
11598 Makefile on the fly based on Makefile.tmpl and Configuration.
11600 *) Apache now gracefully shuts down when it receives a SIGTERM, instead
11601 of forcibly killing off all its processes and exiting without
11602 cleaning up. [Alexei Kosut]
11604 *) API: A new field in the request_rec, r->mtime, has been added to
11605 avoid gratuitous parsing of date strings. It is intended to hold
11606 the last-modified date of the resource (if applicable). An
11607 update_mtime() routine has also been added to advance it if
11608 appropriate. [Roy Fielding, Ken Coar]
11610 *) SECURITY: If a htaccess file can not be read due to bad permissions,
11611 deny access to the directory with a HTTP_FORBIDDEN. The previous
11612 behavior was to ignore the htaccess file if it could not be read.
11613 This change may make some setups with unreadable htaccess files
11614 stop working. [Marc Slemko] PR#817
11616 *) Add aplog_error() providing a mechanism to define levels of
11617 verbosity to the server error logging. This addition also provides
11618 the ability to log errors using syslogd. Error logging is configurable
11619 on a per-server basis using the LogLevel directive. Conversion
11620 of log_*() in progress. [Randy Terbush]
11622 *) Further enhance aplog_error() to not log filename, line number, and
11623 errno information when it isn't applicable. [Ken Coar, Dean Gaudet]
11625 *) WIN32: Canonicalise filenames under Win32. Short filenames are
11626 converted to long ones. Backslashes are converted to forward
11627 slashes. Case is converted to lower. Parts of URLs that do not
11628 correspond to files are left completely alone. [Ben Laurie]
11630 *) PORT: 2 new OSs added to the list of ports:
11631 Encore's UMAX V: Arieh Markel <amarkel encore.com>
11632 Acorn RISCiX: Stephen Borrill <sborrill xemplar.co.uk>
11634 *) Add the server version (SERVER_VERSION macro) to the "server
11635 configured and running" entry in the error_log. Also build an
11636 object file at link-time that contains the current time
11637 (SERVER_BUILT global const char[]), and include that in the
11638 message. [Ken Coar]
11640 *) Set r->headers_out when sending responses from the proxy.
11641 This fixes things such as the logging of headers sent from
11642 the proxy. [Marc Slemko] PR#659
11644 *) support/httpd_monitor is no longer distributed because the
11645 scoreboard should not be file based if at all possible. Use
11646 mod_status to see current server snapshot.
11648 *) (set_file_slot): New function, allowing auth directives to be
11649 independent of the server root, so the server documents can be
11650 moved to a different directory or machine more easily.
11651 [David J. MacKenzie]
11653 *) If no TransferLog is given explicitly, decline
11654 to log. This supports coexistence with other logging modules,
11655 such as the custom one that UUNET uses. [David J. MacKenzie]
11657 *) Check for titles in server-parsed HTML files.
11658 Ignore leading newlines and returns in titles. The old behavior
11659 of replacing a newline after <title> with a space causes the
11660 title to be misaligned in the listing. [David J. MacKenzie]
11662 *) Change mod_cern_meta to be configurable on a per-directory basis.
11663 [David J. MacKenzie]
11665 *) Add 'Include' directive to allow inclusion of configuration
11666 files within configuration files. [Randy Terbush]
11668 *) Proxy errors on connect() are logged to the error_log (nothing
11669 new); now they include the IP address and port that failed
11670 (*that's* new). [Ken Coar, Marc Slemko] PR#352
11672 *) Various architectures now define USE_MMAP_FILES which causes
11673 the server to use mmap() for static files. There are two
11674 compile-time tunables MMAP_THRESHOLD (minimum number of bytes
11675 required to use mmap(), default is 0), and MMAP_SEGMENT_SIZE (maximum
11676 number of bytes written in one cycle from a single mmap()d object,
11677 default 32768). [Dean Gaudet]
11679 *) API: Added post_read_request API phase which is run right after reading
11680 the request from a client, or right after an internal redirect. It is
11681 useful for modules setting environment variables that depend only on
11682 the headers/contents of the request. It does not run during subrequests
11683 because subrequests inherit pretty much everything from the main
11684 request. [Dean Gaudet]
11686 *) Added mod_unique_id which is used to generate a unique identifier for
11687 each hit, available in the environment variable UNIQUE_ID.
11690 *) init_modules is now called after the error logs have been opened. This
11691 allows modules to emit information messages into the error logs.
11694 *) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
11695 information for case where proxy module is not available. [Marc Slemko]
11697 *) PORT: Apache has need for mutexes to serialize its children around
11698 accept. In prior versions either fcntl file locking or flock file
11699 locking were used. The method is chosen by the definition of
11700 USE_xxx_SERIALIZED_ACCEPT in conf.h. xxx is FCNTL for fcntl(),
11701 and FLOCK for flock(). New options have been added:
11702 - SYSVSEM to use System V style semaphores
11703 - PTHREAD to use POSIX threads (appears to work on Solaris only)
11704 - USLOCK to use IRIX uslock
11705 Based on timing various techniques, the following changes were made
11707 - Linux 2.x uses flock instead of fcntl
11708 - Solaris 2.x uses pthreads
11709 - IRIX uses SysV semaphores -- however multiprocessor IRIX boxes
11710 work far faster if you -DUSE_USLOCK_SERIALIZED_ACCEPT
11711 [Dean Gaudet, Pierre-Yves Kerembellec <Pierre-Yves.Kerembellec vtcom.fr>,
11712 Martijn Koster <m.koster pobox.com>]
11714 *) PORT: The semantics of accept/select make it very desirable to use
11715 mutexes to serialize accept when multiple Listens are in use. But
11716 in the case where only a single socket is open it is sometimes
11717 redundant to serialize accept(). Not all unixes do a good job with
11718 potentially dozens of children blocked on accept() on the same
11719 socket. It's now possible to define SINGLE_LISTEN_UNSERIALIZED_ACCEPT and
11720 the server will avoid serialization when listening on only one socket,
11721 and use serialization when listening on multiple sockets.
11722 [Dean Gaudet] PR#467
11724 *) Configure changes: TestLib replaced by TestCompile, which has
11725 some additional capability (such as doing a sanity check of
11726 the compiler and flags selected); the version of Solaris is now
11727 available via the #define value of SOLARIS2; IRIX n32bit libs
11728 now supported and selectable by new Configuration Rule: IRIXN32;
11729 We no longer default to -O2 optimization. [Jim Jagielski]
11731 *) Updated Configure: Configuration now uses AddModule to specify
11732 module source or binary file location, relative to src directory.
11733 Modules can be dropped into modules/extra, or in their own
11734 directory, and modules can come with a Makefile or Configure can
11735 create one. Modules can add compiler or library information to
11736 generated Makefiles. [Paul Sutton]
11738 *) Source core re-organisation: distributed modules are now in
11739 modules/standard. All other source code is in main. OS-specific
11740 code is in os/{unix,emx,win32} directories. [Paul Sutton]
11742 *) mod_browser has been removed, since it's replaced by mod_setenvif.
11745 *) Fix another long-standing bug in sub_req_lookup_file where it would
11746 happily skip past access checks on subdirectories looked up with
11747 relative paths. (It's used by mod_dir, mod_negotiation,
11748 and mod_include.) [Dean Gaudet]
11750 *) directory_walk optimization to reduce an O(N*M) loop to O(N+M) where
11751 N is the number of <Directory> sections, and M is the number of
11752 components in the filename of an object.
11754 To achieve this optimization the following config changes were made:
11755 - Wildcards (* and ?, not the regex forms) in <Directory>s,
11756 <Files>s, and <Location>s now treat a slash as a special
11757 character. For example "/home/*/public_html" previously would
11758 match "/home/a/andrew/public_html", now it only matches things
11759 like "/home/bob/public_html". This mimics /bin/sh behaviour.
11760 - It's possible now to use [] wildcarding in <Directory>, <Files>
11762 - Regex <Directory>s are applied after all non-regex <Directory>s.
11766 *) Fix a bug introduced in 1.3a1 directory_walk regarding .htaccess files
11767 and corrupted paths. [Dean Gaudet]
11769 *) Enhanced and cleaned up the URL rewriting engine of mod_rewrite:
11770 First the grouped parts of RewriteRule pattern matches (parenthesis!) can
11771 be accessed now via backreferences $1..$9 in RewriteConds test-against
11772 strings in addition to RewriteRules subst string. Second the grouped
11773 parts of RewriteCond pattern matches (parenthesis!) can be accessed now
11774 via backreferences %1..%9 both in following RewriteCond test-against
11775 strings and RewriteRules subst string. This provides maximum flexibility
11776 through the use of backreferences.
11777 Additionally the rewriting engine was cleaned up by putting common
11778 code to the new expand_backrefs_inbuffer() function.
11779 [Ralf S. Engelschall]
11781 *) When merging the main server's <Directory> and <Location> sections into
11782 a vhost, put the main server's first and the vhost's second. Otherwise
11783 the vhost can't override the main server. [Dean Gaudet] PR#717
11785 *) The <Directory> code would merge and re-merge the same section after
11786 a match was found, possibly causing problems with some modules.
11789 *) ip-based vhosts are stored and queried using a hashing function, which
11790 has been shown to improve performance on servers with many ip-vhosts.
11791 Some other changes had to be made to accommodate this:
11792 - the * address for vhosts now behaves like _default_
11793 - the matching process now is:
11794 - match an ip-vhost directly via hash (possibly matches main
11796 - if that fails, just pretend it matched the main server
11797 - if so far only the main server has been matched, perform
11798 name-based lookups (ServerName, ServerAlias, ServerPath)
11799 *only on name-based vhosts*
11800 - if they fail, look for _default_ vhosts
11801 [Dean Gaudet, Dave Hankins <dhankins sugarat.net>]
11803 *) dbmmanage overhaul:
11804 - merge dbmmanage and dbmmanage.new functionality, remove dbmmanage.new
11805 - tie() to AnyDBM_File which will use one of DB_File, NDBM_File or
11806 GDBM_File (-ldb, -lndbm, -lgdbm) (trying each in that order)
11807 - provide better seed for rand
11808 - prompt for password as per getpass(3) (turn off echo, read from
11810 - use "newstyle" crypt based on $Config{osname} ($^O)
11811 - will not add a user if already in database, use new `update' command
11813 - added `check' command to check a users' password
11814 - added `import' command to convert existing password text-files or
11815 dbm files exported with `view'
11816 - more descriptive usage, general cleanup, 'use strict' clean, etc.
11819 *) Added psocket() which is a pool form of socket(), various places within
11820 the proxy weren't properly blocking alarms while registering the cleanup
11821 for its sockets. bclose() now uses pclose() and pclosesocket(). There
11822 was a bug where the client socket was being close()d twice due a still
11823 registered cleanup. [Dean Gaudet]
11825 *) A few cleanups were made to reduce time(), getpid(), and signal() calls.
11828 *) PORT: AIX >= 4.2 requires -lm due to libc changes.
11829 [Jason Venner <jason idiom.com>] PR#667
11831 *) Enable ``=""'' for RewriteCond directives to match against
11832 the empty string. This is the preferred way instead of ``^$''.
11833 [Ralf S. Engelschall]
11835 *) Fixed an infinite loop in mod_imap for references above the server root
11836 [Dean Gaudet] PR#748
11838 *) mod_proxy now has a ReceiveBufferSize directive, similar to
11839 SendBufferSize, so that the TCP window can be set appropriately
11840 for LFNs. [Phillip A. Prindeville]
11842 *) mod_browser has been replaced by the more general mod_setenvif
11843 (courtesy of Paul Sutton). BrowserMatch* directives are still
11844 available, but are now joined by SetEnvIf*, UnSetEnvIf*, and
11845 UnSetEnvIfZero directives. [Ken Coar]
11847 *) "HostnameLookups double" forces double-reverse DNS to succeed in
11848 order for remote_host to be set (for logging, or for the env var
11849 REMOTE_HOST). The old define MAXIMUM_DNS has been deprecated.
11852 *) mod_access overhaul:
11853 - Now understands network/netmask syntax (i.e. 10.1.0.0/255.255.0.0)
11854 and cidr syntax (i.e. 10.1.0.0/16). PR#762
11855 - Critical path was sped up by pre-computing a few things at config time.
11856 - The undocumented syntax "allow user-agents" was removed,
11857 the replacement is "allow from env=foobar" combined with mod_browser.
11858 - When used with hostnames it now forces a double-reverse lookup
11859 no matter what the directory settings are. This double-reverse
11860 doesn't affect any of the other routines that use the remote
11861 hostname. In particular it's still passed to CGIs and the log
11862 without the double-reverse check. Related PR#860.
11865 *) When a large bwrite() occurs (larger than the internal buffer size),
11866 while there is already something in the buffer, apache will combine
11867 the large write and the buffer into a single writev(). (This is
11868 in anticipation of using mmap() for reading files.)
11871 *) In obscure cases where a partial socket write occurred while chunking,
11872 Apache would omit the chunk header/footer on the next block. Cleaned
11873 up other bugs/inconsistencies in error conditions in buff.c. Fixed
11874 a bug where a long pause in DNS lookups could cause the last packet
11875 of a response to be unduly delayed. [Roy Fielding, Dean Gaudet]
11877 *) API: Added child_exit function to module structure. This is called
11878 once per "heavy-weight process" just before a server child exit()'s
11879 e.g. when max_requests_per_child is reached, etc.
11880 [Doug MacEachern, Dean Gaudet]
11882 *) mod_include cleanup showed that handle_else was being used to handle
11883 endif. It didn't cause problems, but it was cleaned up too.
11886 *) mod_cern_meta would attempt to find meta files for the directory itself
11887 in some cases, but not in others. It now avoids it in all cases.
11890 *) mod_mime_magic would core dump if there was a decompression error.
11891 [Martin Kraemer <Martin.Kraemer mch.sni.de>] PR#904
11893 *) PORT: some variants of DGUX require -lsocket -lnsl
11894 [Alexander L Jones <alex systems-options.co.uk>] PR#732
11896 *) mod_autoindex now allows sorting of FancyIndexed directory listings
11897 by the various fields (name, size, et cetera), either in ascending
11898 or descending order. Just click on the column header. [Ken Coar]
11900 *) PORT: Various tweaks to eliminate pointer-int casting warnings on 64-bit
11901 CPUs like the Alpha. Apache still stores ints in pointers, but that's
11902 the relatively safe direction. [Dean Gaudet] PR#344
11904 *) PORT: QNX mmap() support for faster/more reliable scoreboard handling.
11905 [Igor N Kovalenko <infoh mail.wplus.net>] PR#683
11907 *) child_main avoids an unneeded call to select() when there is only one
11908 listening socket. [Dean Gaudet]
11910 *) In the event that the server is starved for idle servers it will
11911 spawn 1, then 2, then 4, ..., then 32 servers each second,
11912 doubling each second. It'll also give a warning in the errorlog
11913 since the most common reason for this is a poor StartServers
11914 setting. The define MAX_SPAWN_RATE can be used to raise/lower
11915 the maximum. [Dean Gaudet]
11917 *) Apache now provides an effectively unbuffered connection for
11918 CGI scripts. This means that data will be sent to the client
11919 as soon as the CGI pauses or stops output; previously, Apache would
11920 buffer the output up to a fixed buffer size before sending, which
11921 could result in the user viewing an empty page until the CGI finished
11922 or output a complete buffer. It is no longer necessary to use an
11923 "nph-" CGI to get unbuffered output. Given that most CGIs are written
11924 in a language that by default does buffering (e.g. perl) this
11925 shouldn't have a detrimental effect on performance.
11927 "nph-" CGIs, which formerly provided a direct socket to the client
11928 without any server post-processing, were not fully compatible with
11929 HTTP/1.1 or SSL support. As such they would have had to implement
11930 the transport details, such as encryption or chunking, in order
11931 to work properly in certain situations. Now, the only difference
11932 between nph and non-nph scripts is "non-parsed headers".
11933 [Dean Gaudet, Sameer Parekh, Roy Fielding]
11935 *) If a BUFF is switched from buffered to unbuffered reading the first
11936 bread() will return whatever remained in the buffer prior to the
11937 switch. [Dean Gaudet]
11939 Changes with Apache 1.3a1
11941 *) Added another Configure helper script: TestLib. It determines
11942 if a specified library exists. [Jim Jagielski]
11944 *) PORT: Allow for use of n32bit libraries under IRIX 6.x
11945 [derived from patch from Jeff Hayes <jhayes aw.sgi.com>]
11948 *) PORT: Some architectures use size_t for various lengths in network
11949 functions such as accept(), and getsockname(). The definition
11950 NET_SIZE_T is used to control this. [Dean Gaudet]
11952 *) PORT: Linux: Attempt to detect glibc based systems and include crypt.h
11953 and -lcrypt. Test for various db libraries (dbm, ndbm, db) when
11954 mod_auth_dbm or mod_auth_db are included. [Dean Gaudet]
11956 *) PORT: QNX doesn't have initgroups() which support/suexec.c uses.
11957 [Igor N Kovalenko <infoh mail.wplus.net>]
11959 *) "force-response-1.0" now only applies to requests which are HTTP/1.0 to
11960 begin with. "nokeepalive" now works for HTTP/1.1 clients. Added
11961 "downgrade-1.0" which causes Apache to pretend it received a 1.0.
11962 [Dean Gaudet] related PR#875
11964 *) API: Correct child_init() slot declaration from int to void, to
11965 match the init() declaration. Update mod_example to use the new
11968 *) added transport handle slot (t_handle) to the BUFF structure
11971 *) get_client_block() returns wrong length if policy is
11972 REQUEST_CHUNKED_DECHUNK.
11973 [Kenichi Hori <ken d2.bs1.fc.nec.co.jp>] PR#815
11975 *) Support the image map format of FrontPage. For example:

11977 ["Chris O'Byrne" <obyrne iol.ie>] PR#807
11979 *) PORT: -lresolv and -lsocks were in the wrong order for Solaris.
11980 ["Darren O'Shaughnessy" <darren aaii.oz.au>] PR#846
11982 *) AddModuleInfo directive for mod_info which allows you to annotate
11983 the output of mod_info. ["Lou D. Langholtz" <ldl usi.utah.edu>]
11985 *) Added NoProxy directive to avoid using ProxyRemote for selected
11986 addresses. Added ProxyDomain directive to cause unqualified
11987 names to be qualified by redirection.
11988 [Martin Kraemer <Martin.Kraemer mch.sni.de>]
11990 *) Support Proxy Authentication, and don't pass the Proxy-Authorize
11991 header to the remote host in the proxy. [Sameer Parekh and
11994 *) Upgraded mod_rewrite from 3.0.6+ to latest officially available version
11995 3.0.9. This upgrade includes: fixed deadlooping on rewriting to same
11996 URLs, fixed rewritelog(), fixed forced response code handling on
11997 redirects from within .htaccess files, disabled pipe locking under
11998 braindead SunOS 4.1.x, allow env variables to be set even on rules with
11999 no substitution, bugfixed situations where HostnameLookups is off, made
12000 mod_rewrite more thread-safe for NT port and fixed problem when creating
12001 an empty query string via "xxx?".
12002 This update also removes the copyright of Ralf S. Engelschall,
12003 i.e. now mod_rewrite no longer has a shared copyright. Instead is is
12004 exclusively copyrighted by the Apache Group now. This happened because
12005 the author now has gifted mod_rewrite exclusively to the Apache Group and
12006 no longer maintains an external version.
12007 [Ralf S. Engelschall]
12009 *) API: Added child_init function to module structure. This is called
12010 once per "heavy-weight process" before any requests are handled.
12011 See http_config.h for more details. [Dean Gaudet]
12013 *) Anonymous_LogEmail was logging on each subrequest.
12014 [Dean Gaudet] PR#421, 868
12016 *) API: Added is_initial_req() which tests if the request being
12017 processed is the initial request, or a subrequest.
12020 *) Extended SSI (mod_include) now handles additional relops for
12021 string comparisons (<, >, <=, and >=). [Bruno Wolff III] PR#41
12023 *) Configure fixed to correctly propagate user-selected options and
12024 settings (such as CC and OPTIM) to Makefiles other than
12025 src/Makefile (notably support/Makefile). [Ken Coar] PR#666, #834
12027 *) IndexOptions SuppressHTMLPreamble now causes the actual HTML of
12028 directory indices to start with the contents of the HeaderName file
12029 if there is one. If there isn't one, the behaviour is unchanged.
12030 [Ken Coar, Roy Fielding, Andrey A. Chernov]
12032 *) WIN32: Modules can now be dynamically loaded DLLs using the
12033 LoadModule/LoadFile directives. Note that module DLLs must be
12034 compiled with the multithreaded DLL version of the runtime library.
12035 [Alexei Kosut and Ben Laurie]
12037 *) Automatic indexing removed from mod_dir and placed into mod_autoindex.
12038 This allows the admin to completely remove automatic indexing
12039 from the server, while still supporting the basic functions of
12040 trailing-slash redirects and DirectoryIndex files. Note that if
12041 you're carrying over an old Configuration file and you use directory
12042 indexing then you'll want to add:
12044 Module autoindex_module mod_autoindex.o
12046 before mod_dir in your Configuration. [Dean Gaudet]
12048 *) popendir/pclosedir created to properly protect directory scanning.
12049 [Dean Gaudet] PR#525
12051 *) AliasMatch, ScriptAliasMatch and RedirectMatch directives added,
12052 giving regex support to mod_alias. <DirectoryMatch>, <LocationMatch>
12053 and <FilesMatch> sections added to succeed <DirectoryMatch ~>, etc...
12056 *) The AccessFileName directive can now take more than one filename.
12057 ["Lou D. Langholtz" <ldl usi.utah.edu>]
12059 *) The new mod_mime_magic can be used to "magically" determine the type
12060 of a file if the extension is unknown. Based on the unix file(1)
12061 command. [Ian Kluft <ikluft cisco.com>]
12063 *) We now determine and display the time spent processing a
12064 request if desired. [Jim Jagielski]
12066 *) mod_status: PID field of "dead" child slots no longer displays
12067 main httpd process's PID. [Jim Jagielski]
12069 *) Makefile.nt added - to build all the bits from the command line:
12070 nmake -f Makefile.nt
12071 Doesn't yet work properly. [Ben Laurie]
12073 *) Default text of 404 error is now "Not Found" rather than the
12074 potentially misleading "File Not Found". [Ken Coar]
12076 *) CONFIG: "HostnameLookups" now defaults to off because it is far better
12077 for the net if we require people that actually need this data to
12078 enable it. [Linus Torvalds]
12080 *) directory_walk() is an expensive function, keep a little more state to
12081 avoid needless string counting. Add two new functions make_dirstr_parent
12082 and make_dirstr_prefix which replace all existing uses of make_dirstr.
12083 The new functions are a little less general than make_dirstr, but
12084 work more efficiently (less memory, less string counting).
12087 *) EXTRA_LFLAGS was changed to EXTRA_LDFLAGS (and LFLAGS was changed
12088 to LDFLAGS) to avoid complications with lex rules in make files.
12089 [Dean Gaudet] PR#372
12091 *) run_method optimized to avoid needless scanning over NULLs in the
12092 module list. [Dean Gaudet]
12094 *) Revamp of (unix) scoreboard management code such that it avoids
12095 unnecessary traversals of the scoreboard on each hit. This is
12096 particularly important for high volume sites with a large
12097 HARD_SERVER_LIMIT. Some of the previous operations were O(n^2),
12098 and are now O(n). See also SCOREBOARD_MAINTENANCE_INTERVAL in
12099 httpd.h. [Dean Gaudet]
12101 *) In configurations using multiple Listen statements it was possible for
12102 busy sockets to starve other sockets of service. [Dean Gaudet]
12104 *) Added hook so standalone_main can be replaced at compile time
12105 (define STANDALONE_MAIN)
12108 *) Lowest-level read/write functions in buff.c will be replaced with
12109 the SFIO library calls sfread/sfwrite if B_SFIO is defined at
12110 compile time. The default sfio discipline will behave as apache
12111 would without sfio compiled in.
12114 *) Enhance UserDir directive (mod_userdir) to accept a list of
12115 usernames for the 'disable' keyword, and add 'enable user...' to
12116 selectively *en*able userdirs if they're globally disabled.
12119 *) If NETSCAPE_DBM_COMPAT is defined in EXTRA_CFLAGS then Apache
12120 will work with Netscape dbm files. (dbmmanage will probably not
12121 work however.) [Alexander Spohr <aspohr netmatic.com>] PR#444
12123 *) Add a ListenBacklog directive to control the backlog parameter
12124 passed to listen(). Also change the default to 511 from 512.
12127 *) API: A new handler response DONE which informs apache that the
12128 request has been handled and it can finish off quickly, similar to
12129 how it handles errors. [Rob Hartill]
12131 *) Turn off chunked encoding after sending terminating chunk/footer
12132 so that we can't do it twice by accident. [Roy Fielding]
12134 *) mod_expire also issues Cache-Control: max-age headers.
12137 *) API: Added kill_only_once option for free_proc_chain so that it won't
12138 aggressively try to kill off specific children. For fastcgi.
12139 [Stanley Gambarin <gambarin OpenMarket.com>]
12141 *) mod_auth deals with extra ':' delimited fields. [Marc Slemko]
12143 *) Added IconHeight and IconWidth to mod_dir's IndexOptions directive.
12144 When used together, these cause mod_dir to emit HEIGHT and WIDTH
12145 attributes in the FancyIndexing IMG tags. [Ken Coar]
12147 *) PORT: Sequent and SONY NEWS-OS support added. [Jim Jagielski]
12149 *) PORT: Added Windows NT support
12150 [Ben Laurie and Ambarish Malpani <ambarish valicert.com>]
12152 Changes with Apache 1.2.6
12154 *) mod_include when using XBitHack Full would send ETags in addition to
12155 sending Last-Modifieds. This is incorrect HTTP/1.1 behaviour.
12156 [Dean Gaudet] PR#1133
12158 *) SECURITY: When a client connects to a particular port/addr, and
12159 gives a Host: header ensure that the virtual host requested can
12160 actually be reached via that port/addr. [Ed Korthof <ed organic.com>]
12162 *) Support virtual hosts with wildcard port and/or multiple ports
12163 properly. [Ed Korthof <ed organic.com>]
12165 *) Fixed some case-sensitivity issues according to RFC2068.
12168 *) Set r->allowed properly in mod_asis.c, mod_dir.c, mod_info.c,
12169 and mod_include.c. [Dean Gaudet]
12171 *) Variable 'cwd' was being used pointlessly before being set.
12174 *) SIGURG doesn't exist on all platforms.
12175 [Mark Andrew Heinrich <heinrich tinderbox.Stanford.EDU>]
12177 *) When an error occurs during a POST, or other operation with a
12178 request body, the body has to be read from the net before allowing
12179 a keepalive session to continue. [Roy Fielding] PR#1399
12181 *) When an error occurs in fcntl() locking suggest the user look up
12182 the docs for LockFile. [Dean Gaudet]
12184 *) table_set() and table_unset() did not deal correctly with
12185 multiple occurrences of the same key. [Stephen Scheck
12186 <sscheck infonex.net>, Ben Laurie] PR#1604
12188 *) send_fd_length() did not calculate total_bytes_sent properly in error
12189 cases. [Ben Reser <breser regnow.com>] PR#1366
12191 *) r->connection->user was allocated in the wrong pool causing corruption
12192 in some cases when used with mod_cern_meta. [Dean Gaudet] PR#1500
12194 *) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
12195 Also removed the auto-generated link to www.apache.org that was the
12196 source of so many misdirected bug reports. [Roy Fielding, Marc Slemko]
12198 *) Multiple "close" tokens may have been set in the "Connection"
12199 header, not an error, but a waste.
12200 [<Ronald.Tschalaer psi.ch>] PR#1683
12202 *) "basic" and "digest" auth tokens should be tested case-insensitive.
12203 [<Ronald.Tschalaer psi.ch>] PR#1599, PR#1666
12205 *) It appears the "257th byte" bug (see
12206 htdocs/manual/misc/known_client_problems.html#257th-byte) can happen
12207 at the 256th byte as well. Fixed. [Dean Gaudet]
12209 *) mod_rewrite would not handle %3f properly in some situations.
12212 *) Apache could generate improperly chunked HTTP/1.1 responses when
12213 the bputc() or rputc() functions were used by modules (such as
12214 mod_include). [Dean Gaudet]
12216 *) #ifdef wrap a few #defines in httpd.h to make life easier on
12217 some ports. [Ralf Engelschall]
12219 *) Fix MPE compilation error in mod_usertrack.c. [Mark Bixby]
12221 *) Quote CC='$(CC)' to improve recurse make calls. [Martin Kraemer]
12223 *) Avoid B_ERROR redeclaration on sysvr4 systems. [Martin Kraemer]
12225 Changes with Apache 1.2.5
12227 *) SECURITY: Fix a possible buffer overflow in logresolve. This is
12228 only an issue on systems without a MAXDNAME define or where
12229 the resolver returns domain names longer than MAXDNAME. [Marc Slemko]
12231 *) Fix an improper length in an ap_snprintf call in proxy_date_canon().
12234 *) Fix core dump in the ftp proxy when reading incorrectly formatted
12235 directory listings. [Marc Slemko]
12237 *) SECURITY: Fix possible minor buffer overflow in the proxy cache.
12240 *) SECURITY: Eliminate possible buffer overflow in cfg_getline, which
12241 is used to read various types of files such as htaccess and
12242 htpasswd files. [Marc Slemko]
12244 *) SECURITY: Ensure that the buffer returned by ht_time is always
12245 properly null terminated. [Marc Slemko]
12247 *) SECURITY: General mod_include cleanup, including fixing several
12248 possible buffer overflows and a possible infinite loop. This cleanup
12249 was done against 1.3 code and then backported to 1.2, the result
12250 is a large difference (due to indentation cleanup in 1.3 code).
12251 Users interested in seeing a smaller set of relevant differences
12252 should consider comparing against src/modules/standard/mod_include.c
12253 from the 1.3b3 release. Non-indentation changes to mod_include
12254 between 1.2 and 1.3 were minimal. [Dean Gaudet, Marc Slemko]
12256 *) SECURITY: Numerous changes to mod_imap in a general cleanup
12257 including fixing a possible buffer overflow. This cleanup also
12258 was done with 1.3 code as a basis, see the previous note
12259 about mod_include. [Dean Gaudet]
12261 *) SECURITY: If a htaccess file can not be read due to bad
12262 permissions, deny access to the directory with a HTTP_FORBIDDEN.
12263 The previous behavior was to ignore the htaccess file if it could not
12264 be read. This change may make some setups with unreadable
12265 htaccess files stop working. PR#817 [Marc Slemko]
12267 *) SECURITY: no2slash() was O(n^2) in the length of the input.
12268 Make it O(n). This inefficiency could be used to mount a denial
12269 of service attack against the Apache server. Thanks to
12270 Michal Zalewski <lcamtuf boss.staszic.waw.pl> for reporting
12271 this. [Dean Gaudet]
12273 *) mod_include used uninitialized data for some uses of && and ||.
12274 [Brian Slesinsky <bslesins wired.com>] PR#1139
12276 *) mod_imap should decline all non-GET methods.
12277 [Jay Bloodworth <jay pathways.sde.state.sc.us>]
12279 *) suexec.c wouldn't build without -DLOG_EXEC. [Jason A. Dour]
12281 *) mod_userdir was modifying r->finfo in cases where it wasn't setting
12282 r->filename. Since those two are meant to be in sync with each other
12283 this is a bug. ["Paul B. Henson" <henson intranet.csupomona.edu>]
12285 *) mod_include did not properly handle all possible redirects from sub-

12295 Changes with Apache 1.2.4
12297 *) The ProxyRemote change in 1.2.3 introduced a bug resulting in the proxy
12298 always making requests with the full-URI instead of just the URI path.
12299 [Marc Slemko, Roy Fielding]
12301 *) Add -lm for AIX versions >= 4.2 to allow Apache to link properly
12302 on this platform. [Marc Slemko]
12304 Changes with Apache 1.2.3
12306 *) The request to a remote proxy was mangled if it was generated as the
12307 result of a ProxyPass directive. URL schemes other than http:// were not
12308 supported when ProxyRemote was used. PR#260, PR#656, PR#699, PR#713,

12312 information for case where proxy module is not available. [Marc Slemko]
12314 *) Force proxy to always respond as HTTP/1.0, which it was failing to
12315 do for errors and cached responses. [Roy Fielding]
12317 *) PORT: Improved support for ConvexOS 11. [Jeff Venters]
12319 Changes with Apache 1.2.2 [not released]
12321 *) Fixed another long-standing bug in sub_req_lookup_file where it would
12322 happily skip past access checks on subdirectories looked up with relative
12323 paths. (It's used by mod_dir, mod_negotiation, and mod_include.)
12326 *) Add lockfile name to error message printed out when
12327 USE_FLOCK_SERIALIZED_ACCEPT is defined.
12330 *) Enhanced the chunking and error handling inside the buffer functions.
12331 [Dean Gaudet, Roy Fielding]
12333 *) When merging the main server's <Directory> and <Location> sections into
12334 a vhost, put the main server's first and the vhost's second. Otherwise
12335 the vhost can't override the main server. [Dean Gaudet] PR#717
12337 *) The <Directory> code would merge and re-merge the same section after
12338 a match was found, possibly causing problems with some modules.
12341 *) Fixed an infinite loop in mod_imap for references above the server root.
12342 [Dean Gaudet] PR#748
12344 *) mod_include cleanup showed that handle_else was being used to handle
12345 endif. It didn't cause problems, but it was cleaned up too.
12348 *) Last official synchronization of mod_rewrite with author version (because
12349 mod_rewrite is now directly developed by the author at the Apache Group):
12350 o added diff between mod_rewrite 3.0.6+ and 3.0.9
12351 minus WIN32/NT stuff, but plus copyright removement.
12353 - workaround for detecting infinite rewriting loops
12354 - fixed setting of env vars when "-" is used as subst string
12355 - fixed forced response code on redirects (PR#777)
12356 - fixed cases where r->args is ""
12357 - kludge to disable locking on pipes under braindead SunOS
12358 - fix for rewritelog in cases where remote hostname is unknown
12359 - fixed totally damaged request_rec walk-back loop
12360 o remove static from local data and add static to global ones.
12361 o replaced ugly proxy finding stuff by simple
12362 find_linked_module("mod_proxy") call.
12363 o added missing negation char on rewritelog()
12364 o fixed a few comment typos
12365 [Ralf S. Engelschall]
12367 *) Anonymous_LogEmail was logging on each subrequest.
12368 [Dean Gaudet] PR#421, PR#868
12370 *) "force-response-1.0" now only applies to requests which are HTTP/1.0 to
12371 begin with. "nokeepalive" now works for HTTP/1.1 clients. Added
12372 "downgrade-1.0" which causes Apache to pretend it received a 1.0.
12373 Additionally mod_browser now triggers during translate_name to workaround
12374 a deficiency in the header_parse phase.
12375 [Dean Gaudet] PR#875
12377 *) get_client_block() returns wrong length if policy is
12378 REQUEST_CHUNKED_DECHUNK.
12379 [Kenichi Hori <ken d2.bs1.fc.nec.co.jp>] PR#815
12381 *) Properly treat <files> container like other containers in mod_info.
12382 [Marc Slemko] PR#848
12384 *) The proxy didn't treat the "Host:" keyword of the host header as case-
12385 insensitive. The proxy would corrupt the first line of a response from
12386 an HTTP/0.9 server. [Kenichi Hori <ken d2.bs1.fc.nec.co.jp>] PR#813,814
12388 *) mod_include would log some bogus values occasionally.
12389 [Skip Montanaro <skip calendar.com>, Marc Slemko] PR#797
12391 *) PORT: The slack fd changes in 1.2.1 introduced a problem with SIGHUP
12392 under Solaris 2.x (up through 2.5.1). It has been fixed.
12393 [Dean Gaudet] PR#832
12395 *) API: In HTTP/1.1, whether or not a request message contains a body
12396 is independent of the request method and based solely on the presence
12397 of a Content-Length or Transfer-Encoding. Therefore, our default
12398 handlers need to be prepared to read a body even if they don't know
12399 what to do with it; otherwise, the body would be mistaken for the
12400 next request on a persistent connection. discard_request_body()
12401 has been added to take care of that. [Roy Fielding] PR#378
12403 *) API: Symbol APACHE_RELEASE provides a numeric form of the Apache
12404 release version number, such that it always increases along the
12405 same lines as our source code branching. [Roy Fielding]
12407 *) Minor oversight on multiple variants fixed. [Paul Sutton] PR#94
12409 Changes with Apache 1.2.1
12411 *) SECURITY: Don't serve file system objects unless they are plain files,
12412 symlinks, or directories. This prevents local users from using pipes
12413 or named sockets to invoke programs for an extremely crude form of
12416 *) SECURITY: HeaderName and ReadmeName were settable in .htaccess and
12417 could contain "../" allowing a local user to "publish" any file on
12418 the system. No slashes are allowed now. [Dean Gaudet]
12420 *) SECURITY: It was possible to violate the symlink Options using mod_dir
12421 (headers, readmes, titles), mod_negotiation (type maps), or
12422 mod_cern_meta (meta files). [Dean Gaudet]
12424 *) SECURITY: Apache will refuse to run as "User root" unless
12425 BIG_SECURITY_HOLE is defined at compile time. [Dean Gaudet]
12427 *) CONFIG: If a symlink pointed to a directory then it would be disallowed
12428 if it contained a .htaccess disallowing symlinks. This is contrary
12429 to the rule that symlink permissions are tested with the symlink
12430 options of the parent directory. [Dean Gaudet] PR#353
12432 *) CONFIG: The LockFile directive can be used to place the serializing
12433 lockfile in any location. It previously defaulted to /usr/tmp/htlock.
12434 [Somehow it took four of us: Randy Terbush, Jim Jagielski, Dean Gaudet,
12437 *) Request processing now retains state of whether or not the request
12438 body has been read, so that internal redirects and subrequests will
12439 not try to read it twice (and block). [Roy Fielding]
12441 *) Add a placeholder in modules/Makefile to avoid errors with certain
12442 makes. [Marc Slemko]
12444 *) QUERY_STRING was unescaped in mod_include, it shouldn't be.
12445 [Dean Gaudet] PR#644
12447 *) mod_include was not properly changing the current directory.
12448 [Marc Slemko] PR#742
12450 *) Attempt to work around problems with third party libraries that do not
12451 handle high numbered descriptors (examples include bind, and
12452 solaris libc). On all systems apache attempts to keep all permanent
12453 descriptors above 15 (called the low slack line). Solaris users
12454 can also benefit from adding -DHIGH_SLACK_LINE=256 to EXTRA_CFLAGS
12455 which keeps all non-FILE * descriptors above 255. On all systems
12456 this should make supporting large numbers of vhosts with many open
12457 log files more feasible. If this causes trouble please report it,
12458 you can disable this workaround by adding -DNO_SLACK to EXTRA_CFLAGS.
12459 [Dean Gaudet] various PRs
12461 *) Related to the last entry, network sockets are now opened before
12462 log files are opened. The only known case where this can cause
12463 problems is under Solaris with many virtualhosts and many Listen
12464 directives. But using -DHIGH_SLACK_LINE=256 described above will
12465 work around this problem. [Dean Gaudet]
12467 *) USE_FLOCK_SERIALIZED_ACCEPT is now default for FreeBSD, A/UX, and
12470 *) Improved unix error response logging. [Marc Slemko]
12472 *) Update mod_rewrite from 3.0.5 to 3.0.6. New ruleflag
12473 QSA=query_string_append. Also fixed a nasty bug in per-dir context:
12474 when a URL http://... was used in conjunction with a special
12475 redirect flag, e.g. R=permanent, the permanent status was lost.
12476 [Ronald Tschalaer <Ronald.Tschalaer psi.ch>, Ralf S. Engelschall]
12478 *) If an object has multiple variants that are otherwise equal Apache
12479 would prefer the last listed variant rather than the first.
12480 [Paul Sutton] PR#94
12482 *) "make clean" at the top level now removes *.o. [Dean Gaudet] PR#752
12484 *) mod_status dumps core in inetd mode. [Marc Slemko and Roy Fielding]
12487 *) pregsub had an off-by-1 in its error checking code. [Alexei Kosut]

12510 Changes with Apache 1.2
12512 Changes with Apache 1.2b11
12514 *) Fixed open timestamp fd in proxy_cache.c [Chuck Murcko]
12516 *) Added undocumented perl SSI mechanism for -DUSE_PERL_SSI and mod_perl.
12517 [Doug MacEachern, Rob Hartill]
12519 *) Proxy needs to use hard_timeout instead of soft_timeout when it is
12520 reading from one buffer and writing to another, at least until it has
12521 a custom timeout handler. [Roy Fielding and Petr Lampa]
12523 *) Fixed problem on IRIX with servers hanging in IdentityCheck,
12524 apparently due to a mismatch between sigaction and setjmp.
12525 [Roy Fielding] PR#502
12527 *) Log correct status code if we timeout before receiving a request (408)
12528 or if we received a request-line that was too long to process (414).
12529 [Ed Korthof and Roy Fielding] PR#601
12531 *) Virtual hosts with the same ServerName, but on different ports, were
12532 not being selected properly. [Ed Korthof]
12534 *) Added code to return the requested IP address from proxy_host2addr()
12535 if gethostbyaddr() fails due to reverse DNS lookup problems. Original
12536 change submitted by Jozsef Hollosi <hollosi sbcm.com>.
12537 [Chuck Murcko] PR#614
12539 *) If multiple requests on a single connection are used to retrieve
12540 data from different virtual hosts, the virtual host list would be
12541 scanned starting with the most recently used VH instead of the first,
12542 causing most virtual hosts to be ignored.
12543 [Paul Sutton and Martin Mares] PR#610
12545 *) The OS/2 handling of process group was broken by a porting patch for
12546 MPE, so restored prior code for OS/2. [Roy Fielding and Garey Smiley]
12548 *) Inherit virtual server port from main server if none (or "*") is
12549 given for VirtualHost. [Dean Gaudet] PR#576
12551 *) If the lookup for a DirectoryIndex name with content negotiation
12552 has found matching variants, but none are acceptable, return the
12553 negotiation result if there are no more DirectoryIndex names to lookup.
12554 [Petr Lampa and Roy Fielding]
12556 *) If a soft_timeout occurs after keepalive is set, then the main child
12557 loop would try to read another request even though the connection
12558 has been aborted. [Roy Fielding]
12560 *) Configure changes: Allow for whitespace at the start of a
12561 Module declaration. Also, be more understanding about the
12562 CC=/OPTIM= format in Configuration. Finally, fix compiler
12563 flags if using HP-UX's cc compiler. [Jim Jagielski]
12565 *) Subrequests and internal redirects now inherit the_request from the
12566 original request-line. [Roy Fielding]
12568 *) Test for error conditions before creating output header fields, since
12569 we don't want the error message to include those fields. Likewise,
12570 reset the content_language(s) and content_encoding of the response
12571 before generating or redirecting to an error message, since the new
12572 message will have its own Content-* definitions. [Dean Gaudet]
12574 *) Restored the semantics of headers_out (headers sent only with 200..299
12575 and 304 responses) and err_headers_out (headers sent with all responses).
12576 Avoid the overhead of copying tables if err_headers_out is empty
12577 (the usual case). [Roy Fielding]
12579 *) Fixed a couple places where a check for the default Content-Type was
12580 not properly checking both the value configured by the DefaultType
12581 directive and the DEFAULT_TYPE symbol in httpd.h. Changed the value
12582 of DEFAULT_TYPE to match the documented default (text/plain).
12583 [Dean Gaudet] PR#506
12585 *) Escape the HTML-sensitive characters in the Request-URI that is
12586 output for each child by mod_status. [Dean Gaudet and Ken Coar] PR#501
12588 *) Properly initialize the flock structures used by the mutex locking
12589 around accept() when USE_FCNTL_SERIALIZED_ACCEPT is defined.
12592 *) The method for determining PATH_INFO has been restored to the pre-1.2b
12593 (and NCSA httpd) definition wherein it was the extra path info beyond
12594 the CGI script filename. The environment variable FILEPATH_INFO has
12595 been removed, and instead we supply the original REQUEST_URI to any
12596 script that wants to be Apache-specific and needs the real URI path.
12597 This solves a problem with existing scripts that use extra path info
12598 in the ScriptAlias directive to pass options to the CGI script.
12601 *) The _default_ change in 1.2b10 will change the behaviour on configs
12602 that use multiple Listen statements for listening on multiple ports.
12603 But that change is necessary to make _default_ consistent with other
12604 forms of <VirtualHost>. It requires such configs to be modified
12605 to use <VirtualHost _default_:*>. The documentation has been
12606 updated. [Dean Gaudet] PR#530
12608 *) If an ErrorDocument CGI script is used to respond to an error
12609 generated by another CGI script which has already read the message
12610 body of the request, the server would block trying to read the
12611 message body again. [Rob Hartill]
12613 *) signal() replacement conflicted with a define on QNX (and potentially
12614 other platforms). Fixed. [Ben Laurie] PR#512
12616 Changes with Apache 1.2b10
12618 *) Allow HTTPD_ROOT, SERVER_CONFIG_FILE, DEFAULT_PATH, and SHELL_PATH
12619 to be configured via -D in Configuration. [Dean Gaudet] PR#449
12621 *) <VirtualHost _default_:portnum> didn't work properly. [Dean Gaudet]
12623 *) Added prototype for mktemp() for SUNOS4 [Marc Slemko]
12625 *) In mod_proxy.c, check return values for proxy_host2addr() when reading
12626 config, in case the hostent struct returned is trash.
12627 [Chuck Murcko] PR #491
12629 *) Fixed the fix in 1.2b9 for parsing URL query info into args for CGI
12630 scripts. [Dean Gaudet, Roy Fielding, Marc Slemko]
12632 Changes with Apache 1.2b9 [never announced]
12634 *) Reset the MODULE_MAGIC_NUMBER to account for the unsigned port
12635 changes and in anticipation of 1.2 final release. [Roy Fielding]
12637 *) Fix problem with scripts not receiving a SIGPIPE when client drops
12638 the connection (e.g., when user presses Stop). Apache will now stop
12639 trying to send a message body immediately after an error from write.
12640 [Roy Fielding and Nathan Kurz] PR#335
12642 *) Rearrange Configuration.tmpl so that mod_rewrite has higher priority
12643 than mod_alias, and mod_alias has higher priority than mod_proxy;
12644 rearranged other modules to enhance understanding of their purpose
12645 and relative order (and maybe even reduce some overhead).
12646 [Roy Fielding and Sameer Parekh]
12648 *) Fix graceful restart. Eliminate many signal-related race
12649 conditions in both forms of restart, and in SIGTERM. See
12650 htdocs/manual/stopping.html for details on stopping and
12651 restarting the parent. [Dean Gaudet]
12653 *) Fix memory leaks in mod_rewrite, mod_browser, mod_include. Tune
12654 memory allocator to avoid a behaviour that required extra blocks to
12655 be allocated. [Dean Gaudet]
12657 *) Allow suexec to access files relative to current directory but not
12658 above. (Excluding leading / or any .. directory.) [Ken Coar]
12661 *) Fix suexec segfault when group doesn't exist. [Gregory Neil Shapiro]
12662 PR#367, 368, 354, 453
12664 *) Fix the above fix: if suexec is enabled, avoid destroying r->url
12665 while obtaining the /~user and save the username in a separate data
12666 area so that it won't be overwritten by the call to getgrgid(), and
12667 fix some misuse of the pool string allocation functions. Also fixes
12668 a general problem with parsing URL query info into args for CGI scripts.
12669 [Roy Fielding] PR#339, 367, 354, 453
12671 *) Fix IRIX warning about bzero undefined. [Marc Slemko]
12673 *) Fix problem with <Directory proxy:...>. [Martin Kraemer] PR#271
12675 *) Corrected spelling of "authoritative". AuthDBAuthoratative became
12676 AuthDBAuthoritative. [Marc Slemko] PR#420
12678 *) MaxClients should be at least 1. [Lars Eilebrecht] PR#375
12680 *) The default handler now logs invalid methods or URIs (i.e. PUT on an
12681 object that can't be PUT, or FOOBAR for some method FOOBAR that
12682 apache doesn't know about at all). Log 404s that occur in mod_include.
12683 [Paul Sutton, John Van Essen]
12685 *) If a soft timeout (or lingerout) occurs while trying to flush a
12686 buffer or write inside buff.c or fread'ing from a CGI's output,
12687 then the timeout would be ignored. [Roy Fielding] PR#373
12689 *) Work around a bug in Netscape Navigator versions 2.x, 3.x and 4.0b2's
12690 parsing of headers. If the terminating empty-line CRLF occurs starting
12691 at the 256th or 257th byte of output, then Navigator will think a normal
12692 image is invalid. We are guessing that this is because their initial
12693 read of a new request uses a 256 byte buffer. We check the bytes written
12694 so far and, if we are about to tickle the bug, we instead insert a
12695 padding header of eminent bogosity. [Roy Fielding and Dean Gaudet] PR#232
12697 *) Fixed SIGSEGV problem when a DirectoryIndex file is also the source
12698 of an external redirection. [Roy Fielding and Paul Sutton]
12700 *) Configure would create a broken Makefile if the configuration file
12701 contained a commented-out Rule. [Roy Fielding]
12703 *) Promote per_dir_config and subprocess_env from the subrequest to the
12704 main request in mod_negotiation. In particular this fixes a bug
12705 where <Files> sections wouldn't properly apply to negotiated content.
12708 *) Fix a potential deadlock in mod_cgi script_err handling.
12709 [Ralf S. Engelschall]
12711 *) rotatelogs zero-pads the logfile names to improve alphabetic sorting.
12712 [Mitchell Blank Jr]
12714 *) Updated mod_rewrite to 3.0.4: Fixes HTTP redirects from within
12715 .htaccess files because the RewriteBase was not replaced correctly.
12716 Updated mod_rewrite to 3.0.5: Fixes problem with rewriting inside
12717 <Directory> sections missing a trailing /. [Ralf S. Engelschall]
12719 *) Clean up Linux settings in conf.h by detecting 2.x versus 1.x. For
12720 1.x the settings are those of pre-1.2b8. For 2.x we include
12721 USE_SHMGET_SCOREBOARD (scoreboard in shared memory rather than file) and
12722 HAVE_SYS_RESOURCE_H (enable the RLimit commands).
12723 [Dean Gaudet] PR#336, PR#340
12725 *) Redirect did not preserve ?query_strings when present in the client's
12726 request. [Dean Gaudet]
12728 *) Configure was finding non-modules on EXTRA_LIBS. [Frank Cringle] PR#380
12730 *) Use /bin/sh5 on ULTRIX. [P. Alejandro Lopez-Valencia] PR#369
12732 *) Add UnixWare compile/install instructions. [Chuck Murcko]
12734 *) Add mod_example (illustration of API techniques). [Ken Coar]
12736 *) Add macro for memmove to conf.h for SUNOS4. [Marc Slemko]
12738 *) Improve handling of directories when filenames have spaces in them.
12741 *) For hosts with multiple IP addresses, try all additional addresses if
12742 necessary to get a connect. Fail only if hostent address list is
12743 exhausted. [Chuck Murcko]
12745 *) More signed/unsigned port fixes. [Dean Gaudet]
12747 *) HARD_SERVER_LIMIT can be defined in the Configuration file now.
12750 Changes with Apache 1.2b8
12752 *) suexec.c doesn't close the log file, allowing CGIs to continue writing
12753 to it. [Marc Slemko]
12755 *) The addition of <Location> and <File> directives made the
12756 sub_req_lookup_simple() function bogus, so we now handle
12757 the special cases directly. [Dean Gaudet]
12759 *) We now try to log where the server is dumping core when a fatal
12760 signal is received. [Ken Coar]
12762 *) Improved lingering_close by adding a special timeout, removing the
12763 spurious log messages, removing the nonblocking settings (they
12764 are not needed with the better timeout), and adding commentary
12765 about the NO_LINGCLOSE and USE_SO_LINGER issues. NO_LINGCLOSE is
12766 now the default for SunOS4, UnixWare, NeXT, and IRIX. [Roy Fielding]
12768 *) Send error messages about setsockopt failures to the server error
12769 log instead of stderr. [Roy Fielding]
12771 *) Fix loopholes in proxy cache expiry vis a vis alarms. [Brian Moore]
12773 *) Stopgap solution for CGI 3-second delay with server-side includes: if
12774 processing a subrequest, allocate memory from r->main->pool instead
12775 of r->pool so that we can avoid waiting for free_proc_chain to cleanup
12776 in the middle of an SSI request. [Dean Gaudet] PR #122
12778 *) Fixed status of response when POST is received for a nonexistent URL
12779 (was sending 405, now 404) and when any method is sent with a
12780 full-URI that doesn't match the server and the server is not acting
12781 as a proxy (was sending 501, now 403). [Roy Fielding]
12783 *) Host port changed to unsigned short. [Ken Coar] PR #276
12785 *) Fix typo in command definition of AuthAuthoritative. [Ken Coar] PR #246
12787 *) Defined USE_SHMGET_SCOREBOARD for shared memory on Linux. [Dean Gaudet]
12789 *) Report extra info from errno with many errors that cause httpd to exit.
12790 spawn_child, popenf, and pclosef now have valid errno returns in the
12791 event of an error. Correct problems where errno was stomped on
12792 before being reported. [Dean Gaudet]
12794 *) In the proxy, if the cache filesystem was full, garbage_coll() was
12795 never called, and thus the filesystem would remain full indefinitely.
12796 We now also remove incomplete cache files left if the origin server
12797 didn't send a Content-Length header and either the client has aborted
12798 transfer or bwrite() to client has failed. [Petr Lampa]
12800 *) Fixed the handling of module and script-added header fields.
12801 Improved the interface for sending header fields and reduced
12802 the duplication of code between sending okay responses and errors.
12803 We now always send both headers_out and err_headers_out, and
12804 ensure that the server-reserved fields are not being overridden,
12805 while not overriding those that are not reserved. [Roy Fielding]
12807 *) Moved transparent content negotiation fields to err_headers_out
12808 to reflect above changes. [Petr Lampa]
12810 *) Fixed the determination of whether or not we should make the
12811 connection persistent for all of the cases where some other part
12812 of the server has already indicated that we should not. Also
12813 improved the ordering of the test so that chunked encoding will
12814 be set whenever it is desired instead of only when KeepAlive
12815 is enabled. Added persistent connection capability for most error
12816 responses (those that do not indicate a bad input stream) when
12817 accessed by an HTTP/1.1 client. [Roy Fielding]
12819 *) Added missing timeouts for sending header fields, error responses,
12820 and the last chunk of chunked encoding, each of which could have
12821 resulted in a process being stuck in write forever. Using soft_timeout
12822 requires that the sender check for an aborted connection rather than
12823 continuing after an EINTR. Timeouts that used to be initiated before
12824 send_http_header (and never killed) are now initiated only within or
12825 around the routines that actually do the sending, and not allowed to
12826 propagate above the caller. [Roy Fielding]
12828 *) mod_auth_anon required an @ or a . in the email address, not both.
12831 *) per_dir_defaults weren't set correctly until directory_walk for
12832 name-based vhosts. This fixes an obscure bug with the wrong config
12833 info being used for vhosts that share the same ip as the server.
12836 *) Improved generation of modules/Makefile to be more generic for
12837 new module directories. [Ken Coar, Chuck Murcko, Roy Fielding]
12839 *) Generate makefile dependency for Configuration based on the actual
12840 name given when running the Configure process. [Dean Gaudet]
12842 *) Fixed problem with vhost error log not being set prior to
12843 initializing virtual hosts. [Dean Gaudet]
12845 *) Fixed infinite loop when a trailing slash is included after a type map
12846 file URL (extra path info). [Petr Lampa]
12848 *) Fixed server status updating of per-connection counters. [Roy Fielding]
12850 *) Add documentation for DNS issues (reliability and security), and try
12851 to explain the virtual host matching process. [Dean Gaudet]
12853 *) Try to continue gracefully by disabling the vhost if a DNS lookup
12854 fails while parsing the configuration file. [Dean Gaudet]
12856 *) Improved calls to setsockopt. [Roy Fielding]
12858 *) Negotiation changes: Don't output empty content-type in variant list;
12859 Output charset in variant list; Return sooner from handle_multi() if
12860 no variants found; Add handling of '*' wildcard in Accept-Charset.
12861 [Petr Lampa and Paul Sutton]
12863 *) Fixed overlaying of request/sub-request notes and headers in
12864 mod_negotiation. [Dean Gaudet]
12866 *) If two variants' charset quality are equal and one is the default
12867 charset (iso-8859-1), then prefer the variant that was specifically
12868 listed in Accept-Charset instead of the default. [Petr Lampa]
12870 *) Memory allocation problem in push_array() -- it would corrupt memory
12871 when nalloc==0. [Kai Risku <krisku tf.hut.fi> and Roy Fielding]
12873 *) invoke_handler() doesn't handle mime arguments in content-type
12874 [Petr Lampa] PR#160
12876 *) Reduced IdentityCheck timeout to 30 seconds, as per RFC 1413 minimum.
12879 *) Fixed problem with ErrorDocument not working for virtual hosts
12880 due to one of the performance changes in 1.2b7. [Dean Gaudet]
12882 *) Log an error message if we get a request header that is too long,
12883 since it may indicate a buffer overflow attack. [Marc Slemko]
12885 *) Made is_url() allow "[-.+a-zA-Z0-9]+:" as a valid scheme and
12886 not reject URLs without a double-slash, as per RFC2068 section 3.2.
12887 [Ken Coar] PR #146, #187
12889 *) Added table entry placeholder for new header_parser callback
12890 in all of the distributed modules. [Ken Coar] PR #191
12892 *) Allow for cgi files without the .EXE extension on them under OS/2.
12893 [Garey Smiley] PR #59
12895 *) Fixed error message when resource is not found and URL contains
12896 path info. [Petr Lampa and Dean Gaudet] PR #40
12898 *) Fixed user and server confusion over what should be a virtual host
12899 and what is the main server, resulting in access to something
12900 other than the name defined in the virtualhost directive (but
12901 with the same IP address) failing. [Dean Gaudet]
12903 *) Updated mod_rewrite to version 3.0.2, which: fixes compile error on
12904 AIX; improves the redirection stuff to enable the users to generally
12905 redirect to http, https, gopher and ftp; added TIME variable for
12906 RewriteCond which expands to YYYYMMDDHHMMSS strings and added the
12907 special patterns >STRING, <STRING and =STRING to RewriteCond, which
12908 can be used in conjunction with %{TIME} or other variables to create
12909 time-dependent rewriting rules. [Ralf S. Engelschall]
12911 *) bpushfd() no longer notes cleanups for the file descriptors it is handed.
12912 Module authors may need to adjust their code for proper cleanup to take
12913 place (that is, call note_cleanups_for_fd()). This change fixes problems
12914 with file descriptors being erroneously closed when the proxy module was
12915 in use. [Ben Laurie]
12917 *) Fix bug in suexec reintroduced by changes in 1.2b7 which allows
12918 initgroups() to hose the group information needed for later
12919 comparisons. [Randy Terbush]
12921 *) Remove unnecessary call to va_end() in create_argv() which
12922 caused a SEGV on some systems.
12924 *) Use proper MAXHOSTNAMELEN symbol for limiting length of server name.
12927 *) Clear memory allocated for listeners. [Randy Terbush]
12929 *) Improved handling of IP address as a virtualhost address and
12930 introduced "_default_" as a synonym for the default vhost config.
12931 [Dean Gaudet] PR #212
12933 Changes with Apache 1.2b7
12935 *) Port to UXP/DS(V20) [Toshiaki Nomura <nom yk.fujitsu.co.jp>]
12937 *) unset Content-Length if chunked (RFC-2068) [Petr Lampa]
12939 *) mod_negotiation fixes [Petr Lampa] PR#157, PR#158, PR#159
12940 - replace protocol response numbers with symbols
12941 - save variant-list into main request notes
12942 - free allocated memory from subrequests
12943 - merge notes, headers_out and err_headers_out
12945 *) changed status check mask in proxy_http.c from "HTTP/#.# ### *" to
12946 "HTTP/#.# ###*" to be more lenient about what we accept.
12949 *) more proxy FTP bug fixes:
12950 - Changed send_dir() to remove user/passwd from displayed URL.
12951 - Changed login error messages to be more descriptive.
12952 - remove setting of SO_DEBUG socket option
12953 - Make ftp_getrc() more lenient about multiline responses,
12954 specifically, 230 responses which don't have continuation 230-
12955 on each line). These seem to be all NT FTP servers, and while
12956 perhaps questionable, they appear to be legal by RFC 959.
12957 - Add missing kill_timeout() after transfer to user completes.
12960 *) Fixed problem where a busy server could hang when restarting
12961 after being sent a SIGHUP due to child processes not exiting.
12964 *) Modify mod_include escaping so a '\' only signifies an escaped
12965 character if the next character is one that needs
12966 escaping. [Ben Laurie]
12968 *) Eliminated possible infinite loop in mod_imap when relative URLs are
12969 used with a 'base' directive that does not have a '/' in it.
12970 [Marc Slemko, reported by Onno Witvliet <onno tc.hsa.nl>]
12972 *) Reduced the default timeout from 1200 seconds to 300, and the
12973 one in the sample configfile from 400 to 300. [Marc Slemko]
12975 *) Stop vbprintf from crashing if given a NULL string pointer;
12976 print (null) instead. [Ken Coar]
12978 *) Don't disable Nagle algorithm if system doesn't have TCP_NODELAY.
12979 [Marc Slemko and Roy Fielding]
12981 *) Fixed problem with mod_cgi-generated internal redirects trying to
12982 read the request message-body twice. [Archie Cobbs and Roy Fielding]
12984 *) Reduced timeout on lingering close, removed possibility of a blocked
12985 read causing the child to hang, and stopped logging of errors if
12986 the socket is not connected (reset by client). [Roy Fielding]
12988 *) Rearranged main child loop to remove duplication of code in
12989 select/accept and keep-alive requests, fixed several bugs regarding
12990 checking scoreboard_image for exit indication and failure to
12991 account for all success conditions and trap all error conditions,
12992 prevented multiple flushes before closing the socket; close the entire
12993 socket buffer instead of just one descriptor, prevent logging of
12994 EPROTO and ECONNABORTED on platforms where supported, and generally
12995 improved readability. [Roy Fielding]
12997 *) Extensive performance improvements. Cleaned up inefficient use of
12998 auto initializers, multiple is_matchexp calls on a static string,
12999 and excessive merging of response_code_strings. [Dean Gaudet]
13001 *) Added double-buffering to mod_include to improve performance on
13002 server-side includes. [Marc Slemko]
13004 *) Several fixes for suexec wrapper. [Randy Terbush]
13005 - Make wrapper work for files on NFS filesystem.
13006 - Fix portability problem of MAXPATHLEN.
13007 - Fix array overrun problem in clean_env().
13008 - Fix allocation of PATH environment variable
13010 *) Removed extraneous blank line is description of mod_status chars.
13013 *) Logging of errors from the call_exec routine simply went nowhere,
13014 since the logfile fd has been closed, so now we send them to stderr.
13015 [Harald T. Alvestrand]
13017 *) Fixed core dump when DocumentRoot is a CGI.
13018 [Ben Laurie, reported by <geddis tesserae.com>]
13020 *) Fixed potential file descriptor leak in mod_asis; updated it and
13021 http_core to use pfopen/pfclose instead of fopen/fclose.
13022 [Randy Terbush and Roy Fielding]
13024 *) Fixed handling of unsigned ints in ap_snprintf() on some chips such
13025 as the DEC Alpha which is 64-bit but uses 32-bit ints.
13026 [Dean Gaudet and Ken Coar]
13028 *) Return a 302 response code to the client when sending a redirect
13029 due to a missing trailing '/' on a directory instead of a 301; now
13030 it is cacheable. [Markus Gyger]
13032 *) Fix condition where, if a bad directive occurs in .htaccess, and
13033 sub_request() goes first to this directory, then log_reason() will
13034 SIGSEGV because it doesn't have initialized r->per_dir_config.
13035 [PR#162 from Petr Lampa, fix by Marc Slemko and Dean Gaudet]
13037 *) Fix handling of lang_index in is_variant_better(). This was
13038 causing problems which resulted in the server sending the
13039 wrong language document in some cases. [Petr Lampa]
13041 *) Remove free() from clean_env() in suexec wrapper. This was nuking
13042 the clean environment on some systems.
13044 *) Tweak byteserving code (e.g. serving PDF files) to work around
13045 bugs in Netscape Navigator and Microsoft Internet Explorer.
13046 Emit Content-Length header when sending multipart/byteranges.
13049 *) Port to HI-UX/WE2. [Nick Maclaren]
13051 *) Port to HP MPE operating system for HP 3000 machines
13052 [Mark Bixby <markb cccd.edu>]
13054 *) Fixed bug which caused a segmentation fault if only one argument
13055 given to RLimit* directives. [Ed Korthof]
13057 *) Continue persistent connection after 204 or 304 response. [Dean Gaudet]
13059 *) Improved buffered output to the client by delaying the flush decision
13060 until the BUFF code is actually about to read the next request.
13061 This fixes a problem introduced in 1.2b5 with clients that send
13062 an extra CRLF after a POST request. Also improved chunked output
13063 performance by combining writes using writev() and removing as
13064 many bflush() calls as possible. NOTE: Platforms without writev()
13065 must add -DNO_WRITEV to the compiler CFLAGS, either in Configuration
13066 or Configure, unless we have already done so. [Dean Gaudet]
13068 *) Fixed mod_rewrite bug which truncated the rewritten URL [Marc Slemko]
13070 *) Fixed mod_info output corruption bug introduced by buffer overflow
13071 fixes. [Dean Gaudet]
13073 *) Fixed http_protocol to correctly output all HTTP/1.1 headers, including
13074 for the special case of a 304 response. [Paul Sutton]
13076 *) Improved handling of TRACE method by bypassing normal method handling
13077 and header parsing routines; fixed Allow response to always allow TRACE.
13080 *) Fixed compiler warnings in the regex library. [Dean Gaudet]
13082 *) Cleaned-up some of the generated HTML. [Ken Coar]
13084 Changes with Apache 1.2b6
13086 *) Allow whitespace in imagemap mapfile coordinates. [Marc Slemko]
13088 *) Fix typo introduced in fix for potential infinite loop around
13089 accept() in child_main(). This change caused the rev to 1.2b6.
13090 1.2b5 was never a public beta.
13092 Changes with Apache 1.2b5
13094 *) Change KeepAlive semantics (On|Off instead of a number), add
13095 MaxKeepAliveRequests directive. [Alexei Kosut]
13097 *) Various NeXT compilation patches, as well as a change in
13098 regex/regcomp.c since that file also used a NEXT define.
13101 *) Allow * to terminate the end of a directory match in mod_dir.
13102 Allows /~* to match for both /~joe and /~joe/. [David Bronder]
13104 *) Don't call can_exec() if suexec_enabled. Calling this requires
13105 scripts executed by the suexec wrapper to be world executable, which
13106 defeats one of the advantages of running the wrapper. [Randy Terbush]
13108 *) Portability Fix: IRIX complained with 'make clean' about *pure* (removed)
13111 *) Migration from sprintf() to snprintf() to avoid buffer
13112 overflows. [Marc Slemko]
13114 *) Provide portable snprintf() implementation (ap_snprintf)
13115 as well as *cvt family. [Jim Jagielski]
13117 *) Portability Fix: NeXT lacks unistd.h so we wrap it's inclusion
13120 *) Remove mod_fastcgi.c from the distribution. This module appears
13121 to be maintained more through the Open Market channels and should
13122 continue to be easily available at http://www.fastcgi.com/
13124 *) Fixed bug in modules/Makefile that wouldn't allow building in more
13125 than one subdirectory (or cleaning, either). [Jeremy Laidman]
13127 *) mod_info assumed that the config files were relative to ServerRoot.
13130 *) CGI scripts called as an error document resulting from failed
13131 CGI execution would hang waiting for POST'ed data. [Rob Hartill]
13133 *) Log reason when mod_dir returns access HTTP_FORBIDDEN
13136 *) Properly check errno to prevent display of a directory index
13137 when server receives a long enough URL to confuse stat().
13140 *) Several security enhancements to suexec wrapper. It is _highly_
13141 recommended that previously installed versions of the wrapper
13142 be replaced with this version. [Randy Terbush, Jason Dour]
13144 - ~user execution now properly restricted to ~user's home
13145 directory and below.
13146 - execution restricted to UID/GID > 100
13147 - restrict passed environment to known variables
13148 - call setgid() before initgroups() (portability fix)
13149 - remove use of setenv() (portability fix)
13151 *) Add HTTP/1.0 response forcing. [Ben Laurie]
13153 *) Add access control via environment variables. [Ben Laurie]
13155 *) Add rflush() function. [Alexei Kosut]
13157 *) remove duplicate pcalloc() call in new_connection().
13159 *) Fix incorrect comparison which could allow number of children =
13160 MaxClients + 1 if less than HARD_SERVER_LIMIT. Also fix potential
13161 problem if StartServers > HARD_SERVER_LIMIT. [Ed Korthof]
13163 *) Updated support for OSes (MachTen, ULTRIX, Paragon, ISC, OpenBSD
13164 AIX PS/2, CONVEXOS. [Jim Jagielski]
13166 *) Replace instances of inet_ntoa() with inet_addr() for ProxyBlock.
13167 It's more portable. [Martin Kraemer]
13169 *) Replace references to make in Makefile.tmpl with $(MAKE).
13172 *) Add ProxyBlock directive w/IP address caching. Add IP address
13173 caching to NoCache directive as well. ProxyBlock works with all
13174 handlers; NoCache now also works with FTP for anonymous logins.
13175 Still more code cleanup. [Chuck Murcko]
13177 *) Add "header parse" API hook [Ben Laurie]
13179 *) Fix byte ordering problems for REMOTE_PORT [Chuck Murcko]
13181 *) suEXEC wrapper was freeing memory that had not been malloc'ed.
13183 *) Correctly allow access and auth directives in <Files> sections in
13184 server config files. [Alexei Kosut]
13186 *) Fix bug with ServerPath that could cause certain files to be not
13187 found by the server. [Alexei Kosut]
13189 *) Fix handling of ErrorDocument so that it doesn't remove a trailing
13190 double-quote from text and so that it properly checks for unsupported
13191 status codes using the new index_of_response interface. [Roy Fielding]
13193 *) Multiple fixes to the lingering_close code in order to avoid being
13194 interrupted by a stray timeout, to avoid lingering on a connection
13195 that has already been aborted or never really existed, to ensure that
13196 we stop lingering as soon as any error condition is received, and to
13197 prevent being stuck indefinitely if the read blocks. Also improves
13198 reporting of error conditions. [Marc Slemko and Roy Fielding]
13200 *) Fixed initialization of parameter structure for sigaction.
13201 [<mgyger itr.ch>, Adrian Filipi-Martin]
13203 *) Fixed reinitializing the parameters before each call to accept and
13204 select, and removed potential for infinite loop in accept.
13205 [Roy Fielding, after useful PR from <adrian virginia.edu>]
13207 *) Fixed condition where, if a child fails to fork, the scoreboard would
13208 continue to say SERVER_STARTING forever. Eventually, the main process
13209 would refuse to start new children because count_idle_servers() will
13210 count those SERVER_STARTING entries and will always report that there
13211 are enough idle servers. [Phillip Vandry]
13213 *) Fixed bug in bcwrite regarding failure to account for partial writes.
13214 Avoided calling bflush() when the client is pipelining requests.
13215 Removed unnecessary flushes from http_protocol. [Dean Gaudet]
13217 *) Added description of "." mode in server-status [Jim Jagielski]
13219 Changes with Apache 1.2b4
13221 *) Fix possible race condition in accept_mutex_init() that
13222 could leave a small security hole open allowing files to be
13223 overwritten in cases where the server UID has write permissions.
13226 *) Fix awk compatibilty problem in Configure. [Jim Jagielski]
13228 *) Fix portablity problem in util_script where ARG_MAX may not be
13229 defined for some systems.
13231 *) Add changes to allow compilation on Machten 4.0.3 for PowerPC.
13234 *) OS/2 changes to support an MMAP style scoreboard file and UNIX
13235 style magic #! token for better script portability. [Garey Smiley]
13237 *) Fix bug in suexec wrapper introduced in b3 that would cause failed
13238 execution for ~userdir CGI. [Jason Dour]
13240 *) Fix initgroups() business in suexec wrapper. [Jason Dour]
13242 *) Fix month off by one in suexec wrapper logging.
13244 Changes with Apache 1.2b3:
13246 *) Fix error in mod_cgi which could cause resources not to be properly
13247 freed, or worse. [Dean Gaudet]
13249 *) Fix find_string() NULL pointer dereference. [Howard Fear]
13251 *) Add set_flag_slot() at the request of Dirk and others.
13254 *) Sync mod_rewrite with patch level 10. [Ralf Engelschall]
13256 *) Add changes to improve the error message given for invalid
13257 ServerName parameters. [Dirk vanGulik]
13259 *) Add "Authoritative" directive for Auth modules that don't
13260 currently have it. This gives admin control to assign authoritative
13261 control to an authentication scheme and allow "fall through" for
13262 those authentication modules that aren't "Authoritative" thereby
13263 allowing multiple authentication mechanisms to be chained.
13266 *) Remove requirement for ResourceConfig/AccessConfig if not using
13267 the three config file layout. [Randy Terbush]
13269 *) Add PASV mode to mod_proxy FTP handler. [Chuck Murcko]
13271 *) Changes to suexec wrapper to fix the following problems:
13272 1. symlinked homedirs will kill ~userdirs.
13273 2. initgroups() on Linux 2.0.x clobbers gr->grid.
13274 3. CGI command lines paramters problems
13275 4. pw-pwdir for "docroot check" still the httpd user's pw record.
13276 [Randy Terbush, Jason Dour]
13278 *) Change create_argv() to accept variable arguments. This fixes
13279 a problem where arguments were not getting passed to the CGI via
13280 argv[] when the suexec wrapper was active. [Randy Terbush, Jake Buchholz]
13282 *) Collapse multiple slashes in path URLs to properly apply
13283 handlers defined by <Location>. [Alexei Kosut]
13285 *) Define a sane set of DEFAULT_USER and DEFAULT_GROUP values for AIX.
13287 *) Improve the accuracy of request duration timings by setting
13288 r->request_time in read_request_line() instead of read_request().
13291 *) Reset timeout while reading via get_client_block() in mod_cgi.c
13292 Fixes problem with timed out transfers of large files. [Rasmus Lerdorf]
13294 *) Add the ability to pass different Makefile.tmpl files to Configure
13295 using the -make flag. [Rob Hartill]
13297 *) Fix coredump triggered when sending a SIGHUP to the server caused
13298 by an assertion failure, in turn caused by an uninitialised field in a
13302 *) Add FILEPATH_INFO variable to CGI environment, which is equal to
13303 PATH_INFO from previous versions of Apache (in certain situations,
13304 Apache 1.2's PATH_INFO will be different than 1.1's). [Alexei Kosut]
13305 [later removed in 1.2b11]
13307 *) Add rwrite() function to API to allow for sending strings of
13308 arbitrary length. [Doug MacEachern]
13310 *) Remove rlim_t typedef for NetBSD. Do older versions need this?
13312 *) Defined rlim_t and WANTHSREGEX=yes and fixed waitpid() substitute for
13313 NeXT. [Jim Jagielski]
13315 *) Removed recent modification to promote the status code on internal
13316 redirects, since the correct fix was to change the default log format
13317 in mod_log_config so that it outputs the original status. [Rob Hartill]
13319 Changes with Apache 1.2b2:
13321 *) Update set_signals() to use sigaction() for setting handlers.
13322 This appears to fix a re-entrant problem in the seg_fault()
13323 bus_error() handlers. [Randy Terbush]
13325 *) Changes to allow mod_status compile for OS/2 [Garey Smiley]
13327 *) changes for DEC AXP running OSF/1 v3.0. [Marc Evans]
13329 *) proxy_http.c bugfixes: [Chuck Murcko]
13330 1) fixes possible NULL pointer reference w/NoCache
13331 2) fixes NoCache behavior when using ProxyRemote (ProxyRemote
13332 host would cache nothing if it was in the local domain,
13333 and the local domain was in the NoCache list)
13334 3) Adds Host: header when not available
13335 4) Some code cleanup and clarification
13337 *) mod_include.c bugfixes:
13338 1) Fixed an ommission that caused include variables to not
13339 be parsed in config errmsg directives [Howard Fear]
13340 2) Remove HAVE_POSIX_REGEX cruft [Alexei Kosut]
13341 3) Patch to fix compiler warnings [<perrot lal.in2p3.fr>]
13342 4) Allow backslash-escaping to all quoted text
13343 [Ben Yoshino <ben wiliki.eng.hawaii.edu>]
13344 5) Pass variable to command line if not set in XSSI's env
13347 *) Fix infinite loop when processing Content-language lines in
13348 type-map files. [Alexei Kosut]
13350 *) Closed file-globbing hole in test-cgi script. [Brian Behlendorf]
13352 *) Fixed problem in set_[user|group] that prevented CGI execution
13353 for non-virtualhosts when suEXEC was enabled. [Randy Terbush]
13355 *) Added PORTING information file. [Jim Jagielski]
13357 *) Added definitions for S_IWGRP and S_IWOTH to conf.h [Ben Laurie]
13359 *) Changed default group to "nogroup" instead of "nobody" [Randy Terbush]
13361 *) Fixed define typo of FCNTL_SERIALIZED_ACCEPT where
13362 USE_FCNTL_SERIALIZED_ACCEPT was intended.
13364 *) Fixed additional uses of 0xffffffff where INADDR_NONE was intended,
13365 which caused problems of systems where socket s_addr is >32bits.
13367 *) Added comment to explain (r->chunked = 1) side-effect in
13368 http_protocol.c [Roy Fielding]
13370 *) Replaced use of index() in mod_expires.c with more appropriate
13371 and portable isdigit() test. [Ben Laurie]
13373 *) Updated Configure for ...
13374 OS/2 (DEF_WANTHSREGEX=yes, other code changes)
13375 *-dg-dgux* (bad pattern match)
13376 QNX (DEF_WANTHSREGEX=yes)
13377 *-sunos4* (DEF_WANTHSREGEX=yes, -DUSEBCOPY)
13379 *-unixware211 (new)
13380 and added some user diagnostic info. [Ben Laurie]
13382 *) In helpers/CutRule, replaced "cut" invocation with "awk" invocation
13383 for better portability. [Jim Jagielski]
13385 *) Updated helpers/GuessOS for ...
13386 SCO 5 (recognize minor releases)
13387 SCO UnixWare (braindamaged uname, whatever-whatever-unixware2)
13388 SCO UnixWare 2.1.1 (requires a separate set of #defines in conf.h)
13389 IRIX64 (-sgi-irix64)
13390 ULTRIX (-unknown-ultrix)
13391 SINIX (-whatever-sysv4)
13392 NCR Unix (-ncr-sysv4)
13393 and fixed something in helpers/PrintPath [Ben Laurie]
13395 Changes with Apache 1.2b1
13397 *) Not listed. See <http://www.apache.org/docs/new_features_1_2.html>
13399 Changes with Apache 1.1.1
13401 *) Fixed bug where Cookie module would make two entries in the
13402 logfile for each access [Mark Cox]
13404 *) Fixed bug where Redirect in .htaccess files would cause memory
13405 leak. [Nathan Neulinger]
13407 *) MultiViews now works correctly with AddHandler [Alexei Kosut]
13409 *) Problems with mod_auth_msql fixed [Dirk vanGulik]
13411 *) Fix misspelling of "Anonymous_Authorative" directive in mod_auth_anon.
13413 Changes with Apache 1.1.0
13415 *) Bring NeXT support up to date. [Takaaki Matsumoto]
13417 *) Bring QNX support up to date. [Ben Laurie]
13419 *) Make virtual hosts default to main server keepalive parameters.
13420 [Alexei Kosut, Ben Laurie]
13422 *) Allow ScanHTMLTitles to work with lowercase <title> tags. [Alexei Kosut]
13424 *) Fix missing address family for connect, also remove unreachable statement
13425 in mod_proxy. [Ben Laurie]
13427 *) mod_env now turned on by default in Configuration.tmpl.
13429 *) Bugs which were fixed:
13430 a) yet more mod_proxy bugs [Ben Laurie]
13431 b) CGI works again with inetd [Alexei Kosut]
13432 c) Leading colons were stripped from passwords [<osm interguide.com>]
13433 d) Another fix to multi-method Limit problem [<jk tools.de>]
13435 Changes with Apache 1.1b4
13437 *) r->bytes_sent variable restored. [Robert Thau]
13439 *) Previously broken multi-method <Limit> parsing fixed. [Robert Thau]
13441 *) More possibly unsecure programs removed from the support directory.
13443 *) More mod_auth_msql authentication improvements.
13445 *) VirtualHosts based on Host: headers no longer conflict with the
13448 *) OS/2 compatibility enhancements. [Gary Smiley]
13450 *) POST now allowed to directory index CGI scripts.
13452 *) Actions now work with files of the default type.
13454 *) Bugs which were fixed:
13455 a) more mod_proxy bugs
13456 b) early termination of inetd requests
13457 c) compile warnings on several systems
13458 d) problems when scripts stop reading output early
13460 Changes with Apache 1.1b3
13462 *) Much of cgi-bin and all of cgi-src has been removed, due to
13463 various security holes found and that we could no longer support
13466 *) The "Set-Cookie" header is now special-cased to not merge multiple
13467 instances, since certain popular browsers can not handle multiple
13468 Set-Cookie instructions in a single header. [Paul Sutton]
13470 *) rprintf() added to buffer code, occurrences of sprintf removed.
13473 *) CONNECT method for proxy module, which means tunneling SSL should work.
13474 (No crypto needed) Also a NoCache config directive.
13476 *) Several API additions: pstrndup(), table_unset() and get_token()
13477 functions now available to modules.
13479 *) mod_imap fixups, in particular Location: headers are now complete
13482 *) New "info" module which reports on installed module set through a
13483 special URL, a la mod_status.
13485 *) "ServerPath" directive added - allows for graceful transition
13486 for Host:-header-based virtual hosts.
13488 *) Anonymous authentication module improvements.
13490 *) MSQL authentication module improvements.
13492 *) Status module design improved - output now table-based. [Ben Laurie]
13494 *) htdigest utility included for use with digest authentication
13497 *) mod_negotiation: Accept values with wildcards to be treated with
13498 less priority than those without wildcards at the same quality
13499 value. [Alexei Kosut]
13501 *) Bugs which were fixed:
13502 a) numerous mod_proxy bugs
13503 b) CGI early-termination bug [Ben Laurie]
13504 c) Keepalives not working with virtual hosts
13505 d) RefererIgnore problems
13506 e) closing fd's twice in mod_include (causing core dumps on
13507 Linux and elsewhere).
13509 Changes with Apache 1.1b2
13512 a) core dumps in mod_digest
13513 b) truncated hostnames/ip address in the logs
13514 c) relative URL's in mod_imap map files
13516 Changes with Apache 1.1b1
13518 *) Not listed. See <http://www.apache.org/docs/new_features_1_1.html>
13520 Changes with Apache 1.0.3
13522 *) Internal redirects which occur in mod_dir.c now preserve the
13523 query portion of a request (the bit after the question mark).
13526 *) Escape active characters '<', '>' and '&' in html output in
13527 directory listings, error messages and redirection links.
13530 *) Apache will now work with LynxOS 2.3 and later [Steven Watt]
13532 *) Fix for POSIX compliance in waiting for processes in alloc.c.
13535 *) setsockopt no longer takes a const declared argument [Martijn Koster]
13537 *) Reset timeout timer after each successful fwrite() to the network.
13538 This patch adds a reset_timeout() procedure that is called by
13539 send_fd() to reset the timeout ever time data is written to the net.
13542 *) timeout() signal handler now checks for SIGPIPE and reports
13543 lost connections in a more user friendly way. [Rob Hartill]
13545 *) Location of the "scoreboard" file which used to live in /tmp is
13546 now configurable (for OSes that can't use mmap) via ScoreBoardFile
13547 which works similar to PidFile (in httpd.conf) [Rob Hartill]
13549 *) Include sys/resource.h in the correct place for SunOS4 [Sameer Parekh]
13551 *) the pstrcat call in mod_cookies.c didn't have an ending NULL,
13552 which caused a SEGV with cookies enabled
13554 *) Output warning when MinSpareServers is set to <= 0 and change it to 1
13557 *) Log the UNIX textual error returned by some system calls, in
13558 particular errors from accept() [David Robinson]
13560 *) Add strerror function to util.c for SunOS4 [Randy Terbush]
13562 Changes with Apache 1.0.2
13564 *) patch to get Apache compiled on UnixWare 2.x, recommended as
13565 a temporary measure, pending rewrite of rfc931.c. [Chuck Murcko]
13567 *) Fix get_basic_auth_pw() to set the auth_type of the request.
13570 *) past changes to http_config.c to only use the
13571 setrlimit function on systems defining RLIMIT_NOFILE
13572 broke the feature on SUNOS4. Now defines HAVE_RESOURCE
13573 for SUNOS and prototypes the needed functions.
13575 *) Remove uses of MAX_STRING_LEN/HUGE_STRING_LEN from several routines.
13578 *) Fix use of pointer to scratch memory. [Cliff Skolnick]
13580 *) Merge multiple headers from CGI scripts instead of taking last
13581 one. [David Robinson]
13583 *) Add support for SCO 5. [Ben Laurie]
13585 Changes with Apache 1.0.1
13587 *) Silence mod_log_referer and mod_log_agent if not configured
13590 *) Recursive includes can occur if the client supplies PATH_INFO data
13591 and the server provider uses relative links; as file.html
13592 relative to /doc.shtml/pathinfo is /doc.shtml/file.html. [David Robinson]
13594 *) The replacement for initgroups() did not call {set,end}grent(). This
13595 had two implications: if anything else used getgrent(), then
13596 initgroups() would fail, and it was consuming a file descriptor.
13599 *) On heavily loaded servers it was possible for the scoreboard to get
13600 out of sync with reality, as a result of a race condition.
13601 The observed symptoms are far more Apaches running than should
13602 be, and heavy system loads, generally followed by catastrophic
13603 system failure. [Ben Laurie]
13605 *) Fix typo in license. [David Robinson]
13607 Changes with Apache 1.0.0 23 Nov 1995
13609 *) Not listed. See <http://www.apache.org/docs/new_features_1_0.html>
13611 Changes with Apache 0.8.16 05 Nov 1995
13613 *) New man page for 'httpd' added to support directory [David Robinson]
13615 *) .htgroup files can have more than one line giving members for a
13616 given group (each must have the group name in front), for NCSA
13617 back-compatibility [Robert Thau]
13619 *) Mutual exclusion around accept() is on by default for SVR4 systems
13620 generally, since they generally can't handle multiple processes in
13621 accept() on the same socket. This should cure flaky behavior on
13622 a lot of those systems. [David Robinson]
13624 *) AddType, AddEncoding, and AddLanguage directives take multiple
13625 extensions on a single command line [David Robinson]
13627 *) UserDir can be disabled for a given virtual host by saying
13628 "UserDir disabled" in the <VirtualHost> section --- it was a bug
13629 that this didn't work. [David Robinson]
13631 *) Compiles on QNX [Ben Laurie]
13633 *) Corrected parsing of ctime time format [David Robinson]
13635 *) httpd does a perror() before exiting if it can't log its pid
13636 to the PidFile, to make diagnosing the error a bit easier.
13639 *) <!--#include file="..."--> can no longer include files in the
13640 parent directory, for NCSA back-compatibility. [David Robinson]
13642 *) '~' is *not* escaped in URIs generated for directory listings
13645 *) Eliminated compiler warning in the imagemap module [Randy Terbush]
13647 *) Fixed bug involving handling URIs with escaped %-characters
13648 in redirects [David Robinson]
13650 Changes with Apache 0.8.15 14 Oct 1995
13652 *) Switched to new, simpler license
13654 *) Eliminated core dumps with improperly formatted DBM group files [Mark Cox]
13656 *) Don't allow requests for ordinary files to have PATH_INFO [Ben Laurie]
13658 *) Reject paths containing %-escaped '%' or null characters [David Robinson]
13660 *) Correctly handles internal redirects to files with names containing '%'
13663 *) Repunctuated some error messages [Aram Mirzadeh, Andrew Wilson]
13665 *) Use geteuid() rather than getuid() to see if we have root privilege,
13666 so that server correctly resets privilege if run setuid root. [Andrew
13669 *) Handle ftp: and telnet: URLs correctly in imagemaps (built-in module)
13672 *) Fix relative URLs in imagemap files [Randy Terbush]
13674 *) Somewhat better fix for the old "Alias /foo/ /bar/" business
13677 *) Don't repeatedly open the ErrorLog if a bunch of <VirtualHost>
13678 entries all name the same one. [David Robinson]
13680 *) Fix directory listings with filenames containing unusual characters
13683 *) Better URI-escaping for generated URIs in directories with filenames
13684 containing unusual characters [Ben Laurie]
13686 *) Fixed potential FILE* leak in http_main.c [Ben Laurie]
13688 *) Unblock alarms on error return from spawn_child() [David Robinson]
13690 *) Sample Config files have extra note for SCO users [Ben Laurie]
13692 *) Configuration has note for HP-UX users [Rob Hartill]
13694 *) Eliminated some bogus Linux-only #defines in conf.h [Aram Mirzadeh]
13696 *) Nuked bogus #define in httpd.h [David Robinson]
13698 *) Better test for whether a system has setrlimit() [David Robinson]
13700 *) Calls update_child_status() after reopen_scoreboard() [David Robinson]
13702 *) Doesn't send itself SIGHUP on startup when run in the -X debug-only mode
13705 Changes with Apache 0.8.14 19 Sep 1995
13707 *) Compiles on SCO ODT 3.0 [Ben Laurie]
13709 *) AddDescription works (better) [Ben Laurie]
13711 *) Leaves an intelligible error diagnostic when it can't set group
13712 privileges on standalone startup [Andrew Wilson]
13714 *) Compiles on NeXT again --- the 0.8.13 RLIMIT patch was failing on
13715 that machine, which claims to be BSD but does not support RLIMIT.
13718 *) gcc -Wall no longer complains about an unused variable when util.c
13719 is compiled with -DMINIMAL_DNS [Andrew Wilson]
13721 *) Nuked another compiler warning for -Wall on Linux [Aram Mirzadeh]
13723 Changes with Apache 0.8.13 07 Sep 1995
13725 *) Make IndexIgnore *work* (ooops) [Jarkko Torppa]
13727 *) Have built-in imagemap code recognize & honor Point directive [James
13730 *) Generate cleaner directory listings in directories with a mix of
13731 long and short filenames [Rob Hartill]
13733 *) Properly initialize dynamically loaded modules [Royston Shufflebotham]
13735 *) Properly default ServerName for virtual servers [Robert Thau]
13737 *) Rationalize handling of BSD in conf.h and elsewhere [Randy Terbush,
13738 Paul Richards and a cast of thousands...]
13740 *) On self-identified BSD systems (we don't try to guess any more),
13741 allocate a few extra file descriptors per virtual host with setrlimit,
13742 if we can, to avoid running out. [Randy Terbush]
13744 *) Write 22-character lock file name into buffer with enough space
13745 on startup [Konstantin Olchanski]
13747 *) Use archaic setpgrp() interface on NeXT, which requires it [Brian
13750 *) Suppress -Wall warning by casting const away in util.c [Aram Mirzadeh]
13752 *) Suppress -Wall warning by initializing variable in negotiation code
13753 [Tobias Weingartner]
13755 Changes with Apache 0.8.12 31 Aug 1995
13757 *) Doesn't pause three seconds after including a CGI script which is
13758 too slow to die off (this is done by not even trying to kill off
13759 subprocesses, including the SIGTERM/pause/SIGKILL routine, until
13760 after the entire document has been processed). [Robert Thau]
13762 *) Doesn't do SSI if Options Includes is off. (Ooops). [David Robinson]
13764 *) Options IncludesNoExec allows inclusion of at least text/* [Roy Fielding]
13766 *) Allows .htaccess files to override <Directory> sections naming the
13767 same directory [David Robinson]
13769 *) Removed an efficiency hack in sub_req_lookup_uri which was
13770 causing certain extremely marginal cases (e.g., ScriptAlias of a
13771 *particular* index.html file) to fail. [David Robinson]
13773 *) Doesn't log an error when the requested URI requires
13774 authentication, but no auth header line was supplied by the
13775 client; this is a normal condition (the client doesn't no auth is
13776 needed here yet). [Robert Thau]
13778 *) Behaves more sanely when the name server loses its mind [Sean Welch]
13780 *) RFC931 code compiles cleanly on old BSDI releases [Randy Terbush]
13782 *) RFC931 code no longer passes out name of prior clients on current
13783 requests if the current request came from a server that doesn't
13784 do RFC931. [David Robinson]
13786 *) Configuration script accepts "Module" lines with trailing whitespace.
13789 *) Cleaned up compiler warning from mod_access.c [Robert Thau]
13791 *) Cleaned up comments in mod_cgi.c [Robert Thau]
13793 Changes with Apache 0.8.11 24 Aug 1995
13795 *) Wildcard <Directory> specifications work. [Robert Thau]
13797 *) Doesn't loop for buggy CGI on Solaris [Cliff Skolnick]
13799 *) Symlink checks (FollowSymLinks off, or SymLinkIfOwnerMatch) always check
13800 the file being requested itself, in addition to the directories leading
13801 up to it. [Robert Thau]
13803 *) Logs access failures due to symlink checks or invalid client address
13804 in the error log [Roy Fielding, Robert Thau]
13806 *) Symlink checks deal correctly with systems where lstat of
13807 "/path/to/some/link/" follows the link. [Thau, Fielding]
13809 *) Doesn't reset DirectoryIndex to 'index.html' when
13810 other directory options are set in a .htaccess file. [Robert Thau]
13812 *) Clarified init code and nuked bogus warning in mod_access.c
13813 [Florent Guillaume]
13815 *) Corrected several directives in sample srm.conf
13816 --- includes corrections to directory indexing icon-related directives
13817 (using unknown.gif rather than unknown.xbm as the DefaultIcon, doing
13818 icons for encodings right, and turning on AddEncoding by default).
13821 *) Corrected descriptions of args to AddIcon and AddAlt in command table
13824 *) INSTALL & README mention "contributed modules" directory [Brian
13827 *) Fixed English in the license language... "for for" --> "for".
13830 *) Fixed ScriptAlias/Alias interaction by moving ScriptAlias handling to
13831 mod_alias.c, merging it almost completely with handling of Alias, and
13832 adding a 'notes' field to the request_rec which allows the CGI module
13833 to discover whether the Alias module has put this request through
13834 ScriptAlias (which it needs to know for back-compatibility, as the old
13835 NCSA code did not check Options ExecCGI in ScriptAlias directories).
13838 Changes with Apache 0.8.10 18 Aug 1995
13840 *) AllowOverride applies to the named directory, and not just
13841 subdirectories. [David Robinson]
13843 *) Do locking for accept() exclusion (on systems that need it)
13844 using a special file created for the purpose in /usr/tmp, and
13845 not the error log; using the error log causes real problems
13846 if it's NFS-mounted; this is known to be the cause of a whole
13847 lot of "server hang" problems with Solaris. [David Robinson;
13848 thanks to Merten Schumann for help diagnosing the problem].
13850 Changes with Apache 0.8.9 12 Aug 1995
13852 *) Compiles with -DMAXIMUM_DNS ---- ooops! [Henrik Mortensen]
13854 *) Nested includes see environment variables of the including document,
13855 for NCSA bug-compatibility (some sites have standard footer includes
13856 which try to print out the last-modified date). [Eric Hagberg/Robert
13859 *) <!--exec cgi="/some/uri/here"--> always treats the item named by the
13860 URI as a CGI script, even if it would have been treated as something
13861 else if requested directly, for NCSA back-compatibility. (Note that
13862 this means that people who know the name of the script can see the
13863 code just by asking for it). [Robert Thau]
13865 *) New version of dbmmanage script included in support directory as
13868 *) Check if scoreboard file couldn't be opened, and say so, rather
13869 then going insane [David Robinson]
13871 *) POST to CGI works on A/UX [Jim Jagielski]
13873 *) AddIcon and AddAlt commands work properly [Rob Hartill]
13875 *) NCSA server push works properly --- the Arena bug compatibility
13876 workaround, which broke it, is gone (use -DARENA_BUG_WORKAROUND
13877 if you still want the workaround). [Rob Hartill]
13879 *) If client didn't submit any Accept-encodings, ignore encodings in
13880 content negotiation. (NB this will all have to be reworked anyway
13881 for the new HTTP draft). [Florent Guillaume]
13883 *) Don't dump core when trying to log timed-out requests [Jim Jagielski]
13885 *) Really honor CacheNegotiatedDocs [Florent Guillaume]
13887 *) Give Redirect priority over Alias, for NCSA bug compatibility
13890 *) Correctly set PATH_TRANSLATED in all cases from <!--#exec cmd=""-->,
13891 paralleling earlier bug fix for CGI [David Robinson]
13893 *) If DBM auth is improperly configured, report a server error and don't
13896 *) Deleted FCNTL_SERIALIZED_ACCEPTS from conf.h entry for A/UX;
13897 it seems to work well enough without it (even in a 10 hits/sec
13898 workout), and the overhead for the locking under A/UX is
13899 alarmingly high (though it is very low on other systems).
13900 [Eric Hagberg, Jim Jagielski]
13902 *) Fixed portability problems with mod_cookies.c [Cliff Skolnick]
13904 *) Further de-Berklize mod_cookies.c; change the bogus #include. [Brian
13905 Behlendorf/Eric Hagberg]
13907 *) More improvements to default Configuration for A/UX [Jim Jagielski]
13909 *) Compiles clean on NEXT [Rob Hartill]
13911 *) Compiles clean on SGI [Robert Thau]
13913 Changes with Apache 0.8.8 08 Aug 1995
13915 *) SunOS library prototypes now never included unless explicitly
13916 requested in the configuration (via -DSUNOS_LIB_PROTOTYPES);
13917 people using GNU libc on SunOS are screwed by prototypes for the
13920 (Those who wish to compile clean with gcc -Wall on a standard
13921 SunOS setup need the prototypes, and may obtain them using
13922 -DSUNOS_LIB_PROTOTYPES. Those wishing to use -Wall on a system
13923 with nonstandard libraries are presumably competent to make their
13926 *) Strips trailing '/' characters off both args to the Alias command,
13927 to make 'Alias /foo/ /bar/' work.
13929 Changes with Apache 0.8.7 03 Aug 1995
13931 *) Don't hang when restarting with a child from 'TransferLog "|..."' running
13932 [reported by David Robinson]
13934 *) Compiles clean on OSF/1 [David Robinson]
13936 *) Added some of the more recent significant changes (AddLanguage stuff,
13937 experimental LogFormat support) to CHANGES file in distribution root
13940 Changes with Apache 0.8.6 02 Aug 1995
13942 *) Deleted Netscape reload workaround --- it's in violation of HTTP specs.
13943 (If you actually wanted a conditional GET which bypassed the cache, you
13944 couldn't get it). [Reported by Roy Fielding]
13946 *) Properly terminate headers on '304 Not Modified' replies to conditional
13947 GETs --- no browser we can find cares much, but the CERN proxy chokes.
13948 [Reported by Cliff Skolnick; fix discovered independently by Rob Hartill]
13950 *) httpd -v doesn't call itself "Shambhala". [Reported by Chuck Murcko]
13952 *) SunOS lib-function prototypes in conf.h conditionalized on __GNUC__,
13953 not __SUNPRO_C (they're needed to quiet gcc -Wall, but acc chokes on 'em,
13954 and older versions don't set the __SUNPRO_C preprocessor variable). On
13955 all other systems, these are never used anyway. [Reported by Mark Cox].
13957 *) Scoreboard file (/tmp/htstatus.*) no longer publically writable.
13959 Changes with Apache 0.8.5 01 Aug 1995
13961 *) Added last-minute configurable log experiment, as optional module
13963 *) Correctly set r->bytes_sent for HTTP/0.9 requests, so they get logged
13964 properly. (One-line fix to http_protocol.c).
13966 *) Work around bogus behavior when reloading from Netscape.
13967 It's Netscape's bug --- for some reason they expect a request with
13968 If-modified-since: to not function as a conditional GET if it also
13969 comes with Pragma: no-cache, which is way out of line with the HTTP
13970 spec (according to Roy Fielding, the redactor).
13972 *) Added parameter to set maximum number of server processes.
13974 *) Added patches to make it work on A/UX. A/UX is *weird*. [Eric Hagberg,
13977 *) IdentityCheck bugfix [Chuck Murcko].
13979 *) Corrected cgi-src/Makefile entry for new imagemap script. [Alexei Kosut]
13981 *) More sample config file corrections; add extension to AddType for
13982 *.asis, move AddType generic description to its proper place, and
13983 fix miscellaneous typos. [ Alexei Kosut ]
13985 *) Deleted the *other* reference to the regents from the Berkeley
13986 legal disclaimer (everyplace).
13988 *) Nuked Shambhala name from src/README; had already cleaned it out
13989 of everywhere else.
13991 Changes with Apache 0.8.4
13993 *) Changes to server-pool management parms --- renamed current
13994 StartServers to MinSpareServers, created separate StartServers
13995 parameter which means what it says, and renamed MaxServers to
13996 MaxSpareServers (though the old name still works, for NCSA 1.4
13997 back-compatibility). The old names were generally regarded as
13998 too confusing. Also altered "docs" in sample config files.
14000 *) More improvements to default config files ---
14001 sample directives (commented out) for XBitHack, BindAddress,
14002 CacheNegotiatedDocs, VirtualHost; decent set of AddLanguage
14003 defaults, AddTypes for send-as-is and imagemap magic types, and
14004 improvements to samples for DirectoryIndex [Alexei Kosut]
14006 *) Yet more improvements to default config files --- changes to
14007 Alexei's sample AddLanguage directives, and sample LanguagePriority
14008 [ Florent Guillaume ]
14010 *) Set config file locations properly if not set in httpd.conf
14013 *) Don't escape URIs in internal redirects multiple times; don't
14014 do that when translating PATH_INFO to PATH_TRANSLATED either.
14017 *) Corrected spelling of "Required" in 401 error reports [Andrew Wilson]
14019 Changes with Apache 0.8.3
14021 *) Edited distribution README to *briefly* summarize installation
14022 procedures, and give a pointer to the INSTALL file in the src/
14025 *) Upgraded imagemap script in cgi-bin to 1.8 version from more
14026 recent NCSA distributions.
14028 *) Bug fix to previous bug fix --- if .htaccess file and <Directory>
14029 exist for the same directory, use both and don't segfault. [Reported
14032 *) Proper makefile dependencies [David Robinson]
14034 *) Note (re)starts in error log --- reported by Rob Hartill.
14036 *) Only call no2slash() after get_path_info() has been done, to
14037 preserve multiple slashes in the PATH_INFO [NCSA compatibility,
14038 reported by Andrew Wilson, though this one is probably a real bug]
14040 *) Fixed mod_imap.c --- relative paths with base_uri referer don't
14041 dump core when Referer is not supplied. [Randy Terbush]
14043 *) Lightly edited sample config files to refer people to our documentation
14044 instead of NCSA's, and to list Rob McCool as *original* author (also
14045 deleted his old, and no doubt non-functional email address). Would be
14046 nice to have examples of new features...
14048 Changes with Apache 0.8.2 19 Jul 1995
14050 *) Added AddLanuage code [Florent Guillaume]
14052 *) Don't say "access forbidden" when a CGI script is not found. [Mark Cox]
14054 *) All sorts of problems when MultiViews finds a directory. It would
14055 be nice if mod_dir.c was robust enough to handle that, but for now,
14056 just punt. [reported by Brian Behlendorf]
14058 *) Wait for all children on restart, to make sure that the old socket
14059 is gone and we can reopen it. [reported by Randy Terbush]
14061 *) Imagemap module is enabled in default Configuration
14063 *) RefererLog and UserAgentLog modules properly default the logfile
14066 *) Mark Cox's mod_cookies added to the distribution as an optional
14067 module (commented out in the default Configuration, and noted as
14068 an experiment, along with mod_dld). [Mark Cox]
14070 *) Compiles on ULTRIX (a continuing battle...). [Robert Thau]
14072 *) Fixed nasty bug in SIGTERM handling [reported by Randy Terbush]
14074 *) Changed "Shambhala" to "Apache" in API docs. [Robert Thau]
14076 *) Added new, toothier legal disclaimer. [Robert Thau; copied from BSD
14079 Changes with Apache 0.8.1
14081 *) New imagemap module [Randy Terbush]
14083 *) Replacement referer log module with NCSA-compatible RefererIgnore
14084 [Matthew Gray again]
14086 *) Don't mung directory listings with very long filenames.
14087 [Florent Guillaume]
14089 Changes with Apache 0.8.0 (nee Shambhala 0.6.2) 16 Jul 1995
14091 *) New config script. See INSTALL for info. [Robert Thau]
14093 *) Scoreboard mechanism for regulating the number of extant server
14094 processes. MaxServers and StartServers defaults are the same as
14095 for NCSA, but the meanings are slightly different. (Actually,
14096 I should probably lower the MaxServers default to 10).
14098 Before asking for a new connection, each server process checks
14099 the number of other servers which are also waiting for a
14100 connection. If there are more than MaxServers, it quietly dies
14101 off. Conversely, every second, the root, or caretaker, process
14102 looks to see how many servers are waiting for a new connection;
14103 if there are fewer than StartServers, it starts a new one. This
14104 does not depend on the number of server processes already extant.
14105 The accounting is arranged through a "scoreboard" file, named
14106 /tmp/htstatus.*, on which each process has an independent file
14107 descriptor (they need to seek without interference).
14109 The end effect is that MaxServers is the maximum number of
14110 servers on an *inactive* server machine, but more will be forked
14111 off to handle unusually heavy loads (or unusually slow clients);
14112 these will die off when they are no longer needed --- without
14113 reverting to the overhead of full forking operation. There is a
14114 hard maximum of 150 server processes compiled in, largely to
14115 avoid forking out of control and dragging the machine down.
14116 (This is arguably too high).
14118 In my server endurance tests, this mechanism did not appear to
14119 impose any significant overhead, even after I forced it to put the
14120 scoreboard file on a normal filesystem (which might have more
14121 overhead than tmpfs). [Robert Thau]
14123 *) Set HTTP_FOO variables for SSI <!--#exec cmd-->s, not just CGI scripts.
14126 *) Read .htaccess files even in directory with <Directory> section.
14127 (Former incompatibility noted on mailing list, now fixed). [Robert
14130 *) "HEAD /" gives the client a "Bad Request" error message, rather
14131 than trying to send no body *and* no headers. [Cliff Skolnick].
14133 *) Don't produce double error reports for some very obscure cases
14134 mainly involving auth configuration (the "all modules decline to
14135 handle" case which is a sure sign of a server bug in most cases,
14136 but also happens when authentication is badly misconfigured).
14139 *) Moved FCNTL_SERIALIZED_ACCEPT defines into conf.h (that's what
14140 it's *for*, and this sort of thing really shouldn't be cluttering
14141 up the Makefile). [Robert Thau]
14143 *) Incidental code cleanups in http_main.c --- stop dragging
14144 sa_client around; just declare it where used. [Robert Thau]
14146 *) Another acc-related fix. (It doesn't like const char
14147 in some places...). [Mark Cox]
14149 Changes with Shambhala 0.6.1 13 Jul 1995
14151 *) Fixed auth_name-related typos in http_core.c [Brian Behlendorf]
14152 Also, fixed auth typo in http_protocol.c unmasked by this fix.
14154 *) Compiles clean with acc on SunOS [Paul Sutton]
14156 *) Reordered modules in modules.c so that Redirect takes priority
14157 over ScriptAlias, for NCSA bug-compatibility [Rob Hartill] ---
14158 believe it or not, he has an actual site with a ScriptAlias and
14159 a Redirect declared for the *exact same directory*. Even *my*
14160 compatibility fetish wouldn't motivate me to fix this if the fix
14161 required any effort, but it doesn't, so what the hey.
14163 *) Fixed to properly default several server_rec fields for virtual
14164 servers from the corresponding fields in the main server_rec.
14165 [Cliff Skolnick --- 'port' was a particular irritant].
14167 *) No longer kills off nph- child processes before they are
14168 finished sending output. [Matthew Gray]
14170 Changes with Shambhala 0.6.0 10 Jul 1995
14172 *) Two styles of timeout --- hard and soft. soft_timeout()s just put
14173 the connection to the client in an "aborted" state, but otherwise
14174 allow whatever handlers are running to clean up. hard_timeout()s
14175 abort the request in progress completely; anything not tied to some
14176 resource pool cleanup will leak. They're still around because I
14177 haven't yet come up with a more elegant way of handling
14178 timeouts when talking to something that isn't the client. The
14179 default_handler and the dir_handler now use soft timeouts, largely
14180 so I can test the feature. [Robert Thau]
14182 *) TransferLog "| my_postprocessor ..." seems to be there. Note that
14183 the case of log handlers dying prematurely is probably handled VERY
14184 gracelessly at this point, and if the logger stops reading input,
14185 the server will hang. (It is known to correctly restart the
14186 logging process on server restart; this is (should be!) going through
14187 the same SIGTERM/pause/SIGKILL routine used to ding an errant CGI
14188 script). [Robert Thau]
14190 *) asis files supported (new module). [Robert Thau]
14192 *) IdentityCheck code is compiled in, but has not been tested. (I
14193 don't know anyone who runs identd). [Robert Thau]
14195 *) PATH_INFO and PATH_TRANSLATED are not set unless some real PATH_INFO
14196 came in with the request, for NCSA bug-compatibility. [Robert Thau]
14198 *) Don't leak the DIR * on HEAD request for a directory. [Robert Thau]
14200 *) Deleted the block_alarms() stuff from dbm_auth; no longer necessary,
14201 as timeouts are not in scope. [Robert Thau]
14203 *) quoted-string args in config files now handled correctly (doesn't drop
14204 the last character). [Robert Thau; reported by Randy Terbush]
14206 *) Fixed silly typo in http_main.c which was suddenly fatal in HP-UX.
14207 How the hell did it ever work? [Robert Thau; reported by Rob Hartill]
14209 *) mod_core.c --- default_type returns DEFAULT_TYPE (the compile-time
14210 default default type); the former default default behavior when all
14211 type-checkers defaulted had been a core dump. [Paul Sutton]
14213 *) Copy filenames out of the struct dirent when indexing
14214 directories. (On Linux, readdir() returns a pointer to the same
14215 memory area every time). Fix is in mod_dir.c. [Paul Sutton]
14217 Changes with Shambhala 0.5.3 [not released]
14219 *) Default response handler notes "file not found" in the error log,
14220 if the file was not found. [Cliff Skolnick].
14222 *) Another Cliff bug --- "GET /~user" now properly redirects (the userdir
14223 code no longer sets up bogus PATH_INFO which fakes out the directory
14224 handler). [Cliff Skolnick]
14226 Changes with Shambhala 0.5.2 06 Jul 1995
14228 *) Changes to http_main.c --- root server no longer plays silly
14229 games with SIGCHLD, and so now detects and replaces dying
14230 children. Child processes just die on SIGTERM, without taking
14231 the whole process group with them. Potential problem --- if any
14232 child process refuses to die, we hang in restart.
14233 MaxRequestsPerChild may still not work, but it certainly works
14234 better than it did before this! [Robert Thau]
14236 *) mod_dir.c bug fixes: ReadmeName and HeaderName
14237 work (or work better, at least); over-long description lines
14238 properly terminated. [Mark Cox]
14240 *) http_request.c now calls unescape_url() more places where it
14241 should [Paul Sutton].
14243 *) More directory handling bugs (reported by Cox)
14244 Parent Directory link is now set correctly. [Robert Thau]
14246 Changes with Shambhala 0.5.1 04 Jul 1995
14248 *) Generalized cleanup interface in alloc.c --- any function can be
14249 registered with alloc.c as a cleanup for a resource pool;
14250 tracking of files and file descriptors has been reimplemented in
14251 terms of this interface, so I can give it some sort of a test.
14254 *) More changes in alloc.c --- new cleanup_for_exec() function,
14255 which tracks down and closes all file descriptors which have been
14256 registered with the alloc.c machinery before the server exec()s a
14257 child process for CGI or <!--#exec-->. CGI children now get
14258 started with exactly three file descriptors open. Hopefully,
14259 this cures the problem Rob H. was having with overly persistent
14260 CGI connections. [Robert Thau]
14262 *) Mutual exclusion around the accept() in child_main() --- this is
14263 required on at least SGI, Solaris and Linux, and is #ifdef'ed in
14264 by default on those systems only (-DFCNTL_SERIALIZED_ACCEPT).
14265 This uses fcntl(F_SETLK,...) on the error log descriptor because
14266 flock() on that descriptor won't work on systems which have BSD
14267 flock() semantics, including (I think) Linux 1.3 and Solaris.
14269 This does work on SunOS (when the server is idle, only one
14270 process in the pool is waiting on accept()); it *ought* to work
14271 on the other systems. [Robert Thau]
14273 *) FreeBSD and BSDI portability tweaks [Chuck Murcko]
14275 *) sizeof(*sa_client) bugfix from [Rob Hartill]
14277 *) pstrdup(..., NULL) returns NULL, [Randy Terbush]
14279 *) block_alarms() to avoid leaking the DBM* in dbm auth (this should
14280 be unnecessary if I go to the revised timeout-handling scheme).
14283 *) For NCSA bug-compatibility, set QUERY_STRING env var (to a null
14284 string) even if none came in with the request. [Robert Thau]
14286 *) CHANGES file added to distribution ;-).
14288 Changes with Shambhala 0.4.5
14290 *) mod_dld --- early dynamic loading support [rst]
14291 *) Add wildcard content handlers for XBITHACK; default_hander now
14292 invoked with that mechanism (as a handler hanging off mod_core) [rst]
14293 *) XBITHACK supported as a wildcard content-handler, and
14294 configurable at run-time (not just at compile time, as in the
14295 "patchy server" releases) [rst]
14297 Changes with Shambhala 0.4.4 30 Jun 1995
14299 *) Fixed basic thinkos in mod_dbm_auth.c [rst, reported by Mark Cox]
14300 *) Handle Addtype x/y .z [rst, reported by Cox]
14302 Changes with Shambhala 0.4.3
14304 *) Fixed very dumb bug in mod_alias; "Alias" and "Redirect" are not
14305 synonymous [rst, terbush]
14307 Changes with Shambhala 0.4.1 28 Jun 1995
14309 *) First-cut virtual host implementation; some refit in the config
14310 reading code, and log management, was necessary to support this [rst]
14311 *) Sub-pool machinery, originally added to avoid excessive storage
14312 allocation on listings of large directories (which turned out to
14313 be the problem that the 0.3 storage accounting was added to
14314 find). Subrequests and mod_dir changed to use subpools. [rst]
14315 *) More memory debugging --- free list consistency checks. [rst]
14316 *) Added err_headers to request_rec, with support elsewhere [rst]
14317 *) Other fixes to minor bugs in mod_dir and mod_includes [rst, terbush]
14319 Changes with Shambhala 0.3 19 Jun 1995
14321 *) Switch ONE_PROCESS to a runtime command-line option (-X)
14322 *) Don't compile in mod_ai_backcompat by default
14323 *) Switch name of server from Apache to Shambhala in Makefile
14324 *) Add some accounting routines to track memory usage in the pools,
14327 Changes with Shambhala 0.2
14329 *) Set DOCUMENT_ROOT CGI variable
14330 *) Add single-process debugging, as a compile-time option (ONE_PROCESS)
14331 *) Add critical section protection to handling of cleanup structures
14333 *) Significant code reorg within the server core to group related
14334 functions together [rst]
14335 *) Correctly handle clients that hang up before sending any request
14337 *) Replace dying child processes. [rst]
14339 Changes with Shambhala 0.1 12 Jun 1995
14341 Major rewrite of the pre-existing "patchy server" codebase, by
14342 Robert Thau (rst). Significant portions of the server code, such
14343 as configuration-file handling and HTTP authentication support,
14344 were ripped out and rewritten from scratch. Code that was not
14345 completely rewritten was significantly altered.
14347 Major changes with this release include:
14349 *) Introduction of the module API; in request handling, the central
14350 machinery just dispatches to various modules, which actually do
14351 most of the work. Configuration handling is similar --- modules
14352 declare their own commands, and the central machinery just
14353 dispatches to them.
14355 API features from shambhala/0.1 were substantially unchanged in
14356 Apache 1.0 and 1.1. (1.0 API features not yet present in this
14357 release, such as wildcard handlers and subpools, were added in
14358 subsequent Shambhala releases, and were also generally rst's
14361 *) This release included the following modules:
14363 mod_access (access control --- allow and deny directives),
14364 mod_alias (Alias and Redirect commands),
14365 mod_auth (straight HTTP authentication, based on flat-files)
14366 mod_auth_dbm (same, with dbm files)
14367 mod_cgi (CGI scripts and, in this release, ScriptAlias)
14368 mod_common_log (CLF access logs; later renamed mod_log_common)
14369 mod_dir (directory indexing)
14370 mod_include (server-side includes)
14371 mod_mime (AddType directives)
14372 mod_negotiation (content negotiation)
14373 mod_userdir (support for users' public_html directories)
14375 It also included a mod_ai_backcompat, which was a private hack
14376 for back-compatibility with rst's own AI-lab servers.
14378 All of these modules were substantially complete, and functional
14379 or nearly so (a few, which implemented features not in use at
14380 Thau's site, required patches of a few lines).
14382 *) sub-request machinery, to allow modules to determine how other
14383 modules would assign MIME types to a given file, or optionally
14384 serve its content (this is heavily used by mod_dir, mod_include
14385 and mod_negotiation).
14387 *) Resource pool system for keeping track of memory allocated and
14388 files opened in service of a particular request. Much of the
14389 code in the modules (when they weren't rewrites) was adjusted to
14390 replace a pervasive convention of using fixed-size buffers on
14391 the stack with an equally pervasive convention of using memory
14392 allocated with palloc().
14394 *) Reorganization of data structures associated with a given
14395 request to eliminate use of global variables and the troublesome
14396 unmunge_name function (used in NCSA and early Apache releases to
14397 attempt to determine the URI which mapped to a given filename
14398 --- a difficult proposition, given that it is easy to produce
14399 setups in which multiple URIs map to the same file).
14401 *) Source files renamed and rearranged
14403 *) Very simple pre-forking behavior --- parent process forked off a
14404 fixed number of children, and then just waited for SIGHUP.
14406 *) Other more minor changes too numerous to list.
14408 This release included modified versions of a lot of code from the
14409 Apache 0.6.4 public release, plus an early pre-forking patch
14410 codeveloped by Robert Thau and Rob Hartill.
14412 Changes with Apache 0.7.3 20 Jun 1995
14414 *) There were a bunch of changes between Apache 0.6.4 and 0.7.3 that
14415 were incorporated by Rob Hartill on the main branch while Robert Thau
14416 worked on the Shambhala rewrite above. Most were merged into the
14417 Shambala architecture after Apache 0.8.0.
14419 Changes with Apache 0.6.4 13 May 1995
14421 *) Patches by Rob Hartill, Cliff Skolnick, Randy Terbush, Robert Thau,
14424 Changes with Apache 0.5.1 10 Apr 1995
14426 Changes with Apache 0.4 02 Apr 1995
14428 *) Patches by Brian Behlendorf, Andrew Wilson, Robert Thau,
14431 Changes with Apache 0.3 24 Mar 1995
14433 *) Patches by Robert Thau, David Robinson, Rob Hartill, and
14436 Changes with Apache 0.2 18 Mar 1995
14438 *) Based on NCSA httpd 1.3 by Rob McCool and patches by CERT,
14439 Roy Fielding, Robert Thau, Nicolas Pioch, David Robinson,
14440 Brian Behlendorf, Rob Hartill, and Cliff Skolnick.
