2 Changes with Apache 2.3.0
3 [Remove entries to the current 2.0 and 2.2 section below, when backported]
5 *) apxs: Enhance -q flag to print all known variables and their values
6 when invoked without variable name(s).
7 [William Rowe, Sander Temme]
9 *) mod_dbd: Create memory sub-pools for each DB connection and close
10 DB connections in a pool cleanup function. Ensure prepared statements
11 are destroyed before DB connection is closed. When using reslists,
12 prevent segfaults when child processes exit, and stop memory leakage
13 of ap_dbd_t structures. Avoid use of global s->process->pool, which
14 isn't destroyed by exiting child processes in most multi-process MPMs.
15 PR 39985. [Chris Darroch, Nick Kew]
17 *) apxs: Eliminate run-time check for mod_so. PR 40653.
18 [David M. Lee <dmlee crossroads.com>]
20 *) beos MPM: Create pmain pool and run modules' child_init hooks when
21 entering ap_mpm_run(), then destroy pmain when exiting ap_mpm_run().
24 *) netware MPM: Destroy pmain pool when exiting ap_mpm_run() so that
25 cleanups registered in modules' child_init hooks are performed.
28 *) mod_dbd: Handle error conditions in dbd_construct() properly.
29 Simplify ap_dbd_open() and use correct arguments to apr_dbd_error()
30 when non-threaded. Register correct cleanup data in non-threaded
31 ap_dbd_acquire() and ap_dbd_cacquire(). Clean up configuration data
32 and merge function. Use ap_log_error() wherever possible.
33 [Chris Darroch, Nick Kew]
35 *) mod_proxy_http: Handle request bodies larger than 2 GB by converting
36 the Content-Length header of the request correctly. PR 40883.
37 [Ruediger Pluem, toadie <toadie643 gmail.com>]
39 *) core: Do not replace a Date header set by a proxied backend server.
40 PR 40232. [Ruediger Pluem]
42 *) mod_proxy: Ensure that at least scheme://hostname[:port] matches between
43 worker and URL when searching for the best fitting worker for a given URL.
44 PR 40910. [Ruediger Pluem]
46 *) mod_cache: Remove expired content from cache that cannot be revalidated.
47 PR 30370. [Ruediger Pluem]
49 *) mod_dbd: Stash DBD connections in request_config of initial request
50 only, or else sub-requests and internal redirections may cause
51 entire DBD pool to be stashed in a single HTTP request. [Chris Darroch]
53 *) mod_cache: Correctly cache objects whose URL query string has been
54 modified by mod_rewrite. PR 40805. [Ruediger Pluem]
56 *) mod_proxy: Add a missing assignment in an error checking code path.
57 PR 40865. [Andrew Rucker Jones <arjones simultan.dyndns.org>]
59 *) mod_mem_cache: Increase the minimum and default value for
60 MCacheMinObjectSize from 0 to 1, as a MCacheMinObjectSize of 0 does not
61 make sense and leads to a division by zero. PR 40576.
62 [Xuekun Hu <xuekun.hu gmail.com>]
64 *) Fix issue which could cause error messages to be written to access logs
65 on Win32. PR 40476. [Tom Donovan <Tom.Donovan acm.org>]
67 *) The LockFile directive, which specifies the location of
68 the accept() mutex lockfile, is depreciated. Instead, the
69 AcceptMutex directive now takes an optional lockfile
70 location parameter, ala SSLMutex. [Jim Jagielski]
72 *) mod_authn_dbd: Export any additional columns queried in the SQL select
73 into the environment with the name AUTHENTICATE_<COLUMN>. This brings
74 mod_authn_dbd behaviour in line with mod_authnz_ldap. [Graham Leggett]
76 *) mod_dbd: Key the storage of prepared statements on the hex string
77 value of server_rec, rather than the server name, as the server name
78 may change (eg when the server name is set) at any time, causing
79 weird behaviour in modules dependent on mod_dbd. [Graham Leggett]
81 *) mod_proxy_fcgi: Added win32 build. [Mladen Turk]
83 *) sendfile_nonblocking() takes the _brigade_ as an argument, gets
84 the first bucket from the brigade, finds it not to be a FILE
85 bucket and barfs. The fix is to pass a bucket rather than a brigade.
86 [Niklas Edmundsson <nikke acc.umu.se>]
88 *) mod_rewrite: support rewritemap by SQL query [Nick Kew]
90 *) mod_proxy: Print the correct error message for erroneous configured
91 ProxyPass directives. PR 40439. [serai lans-tv.com]
93 *) ap_get_server_version() has been removed. Third-party modules must
94 now use ap_get_server_banner() or ap_get_server_description().
97 *) All MPMs: Introduce a check_config phase between pre_config and
98 open_logs, to allow modules to review interdependent configuration
99 directive values and adjust them while messages can still be logged
100 to the console. Handle relevant MPM directives during this phase
101 and format messages for both the console and the error log, as
102 appropriate. [Chris Darroch]
104 *) mod_proxy: don't URLencode tilde in path component
105 [Stijn Hoop <stijn sandcat.nl>]
107 *) mpm_winnt: Fix return values from wait_for_many_objects.
108 The return value is index to the signaled thread in the
109 creted_threads array. We can not use WAIT_TIMEOUT because
110 his value is defined as 258, thus limiting the MaxThreads
111 to that value. [Mladen Turk]
113 *) mod_cache: While serving a cached entity ensure that filters that have
114 been applied to this cached entity before saving it to the cache are not
115 applied again. PR 40090. [Ruediger Pluem]
117 *) core: Do not allow internal redirects like the DirectoryIndex of mod_dir
118 to circumvent the symbolic link checks imposed by FollowSymLinks and
119 SymLinksIfOwnerMatch. [Nick Kew, Ruediger Pluem, William Rowe]
121 *) mod_proxy: Support environment variable interpolation in reverse
122 proxying directives. [Nick Kew]
124 *) core: Add the filename of the configuration file to the warning message
125 about the useless use of AllowOverride. PR 39992.
126 [Darryl Miles <darryl darrylmiles.org>]
128 *) New SSLLogLevelDebugDump [ None (default) | IO (not bytes) | Bytes ]
129 configures the I/O Dump of SSL traffic, when LogLevel is set to Debug.
130 The default is none as this is far greater debugging resolution than
131 the typical administrator is prepared to untangle. [William Rowe]
133 *) mod_disk_cache: If possible, check if the size of an object to cache is
134 within the configured boundaries before actually saving data.
135 [Niklas Edmundsson <nikke acc.umu.se>]
137 *) mod_cache: Convert all values to seconds before comparing them when
138 checking whether to send a Warning header for a stale response.
139 PR 39713. [Owen Taylor <otaylor redhat.com>]
141 *) mod_disk_cache: Delete temporary files if they cannot be renamed to their
142 final name. [Davi Arnaut <davi haxent.com.br>]
144 *) Worker and event MPMs: Remove improper scoreboard updates which were
145 performed in the event of a fork() failure. [Chris Darroch]
147 *) Add support for fcgi:// proxies to mod_rewrite.
148 [Markus Schiegl <ms schiegl.com>]
150 *) Remove incorrect comments from scoreboard.h regarding conditional
151 loading of worker_score structure with mod_status, and remove unused
152 definitions relating to old life_status field.
153 [Chris Darroch <chrisd pearsoncmg.com>]
155 *) Remove allocation of memory for unused array of lb_score pointers
156 in ap_init_scoreboard(). [Chris Darroch <chrisd pearsoncmg.com>]
158 *) Add mod_proxy_fcgi, a FastCGI back end for mod_proxy.
159 [Garrett Rooney, Jim Jagielski, Paul Querna]
161 *) Event MPM: Fill in the scoreboard's tid field. PR 38736.
162 [Chris Darroch <chrisd pearsoncmg.com>]
164 *) mod_charset_lite: Remove Content-Length when output filter can
165 invalidate it. Warn when input filter can invalidate it.
168 *) mod_ssl: Fix spurious hostname mismatch warning for valid
169 wildcard certificates. PR 37911. [Nick Burch <nick torchbox.com>]
171 *) Authz: Add the new module mod_authn_core that will provide common
172 authn directives such as 'AuthType', 'AuthName'. Move the directives
173 'AuthType' and 'AuthName' out of the core module and merge mod_authz_alias
174 into mod_authn_core. [Brad Nicholes]
176 *) Authz: Mark the directives 'Order', 'Allow', 'Deny' and 'Satisfy' as
177 deprecated and move them into the new module mod_access_compat which
178 can be loaded to provide backwards compatibility for these directives.
181 *) Authz: Move the 'Require' directive from the core module as well as
182 add the directives '<SatisfyAll>', '<SatisfyOne>', '<RequireAlias>'
183 and 'Reject' to mod_authz_core. The new directives introduce 'AND/OR'
184 logic into the authorization processing. [Brad Nicholes]
186 *) Authz: Add the new module mod_authz_core which acts as the
187 authorization provider vector and contains common authz
188 directives. [Brad Nicholes]
190 *) Authz: Renamed mod_authz_dbm authz providers from 'group' and
191 'file-group' to 'dbm-group' and 'dbm-file-group'. [Brad Nicholes]
193 *) Authz: Added the new authz providers 'env', 'ip', 'host', 'all' to handle
194 host-based access control provided by mod_authz_host and invoked
195 through the 'Require' directive. [Brad Nicholes]
197 *) Authz: Convert all of the authz modules from hook based to
198 provider based. [Brad Nicholes]
200 *) mod_cache: Add CacheMinExpire directive to set the minimum time in
201 seconds to cache a document.
202 [Brian Akins <brian.akins turner.com>, Ruediger Pluem]
204 *) mod_authz_dbd: SQL authz with Login/Session support [Nick Kew]
206 *) Fix typo in ProxyStatus syntax error message.
207 [Christophe Jaillet <christophe.jaillet wanadoo.fr>]
209 *) Asynchronous write completion for the Event MPM. [Brian Pane]
211 *) Added an End-Of-Request bucket type. The logging of a request and
212 the freeing of its pool are now done when the EOR bucket is destroyed.
213 This has the effect of delaying the logging until right after the last
214 of the response is sent; ap_core_output_filter() calls the access logger
215 indirectly when it destroys the EOR bucket. [Brian Pane]
217 *) Rewrite of logresolve support utility: IPv6 addresses are now supported
218 and the format of statistical output has changed. [Colm MacCarthaigh]
220 *) Rewrite of ap_coreoutput_filter to do nonblocking writes [Brian Pane]
222 *) Added new connection states for handler and write completion
225 *) mod_cgid: Refuse to work on Solaris 10 due to OS bugs. PR 34264.
228 *) Teach mod_ssl to use arbitrary OIDs in an SSLRequire directive,
229 allowing string-valued client certificate attributes to be used for
230 access control, as in: SSLRequire "value" in OID("1.3.6.1.4.1.18060.1")
231 [Martin Kraemer, David Reid]
233 Changes with Apache 2.2.5
235 *) Unix MPMs: Catch SIGFPE so that exception hooks and CoreDumpDirectory
236 can work after that terminating signal.
237 [Eric Covener <covener gmail.com>]
239 *) Win32: Makefile.win will now build with MS VC 8 (Visual Studio 2005)
240 including embedding the .manifest information into each binary.
243 Changes with Apache 2.2.4
245 *) mod_isapi: Correctly present SERVER_PORT_SECURE.
246 PR: 40573. [Matt Eaton <asf divinehawk.com>]
248 *) Allow htcacheclean, httxt2dbm, and fcgistarter to link apr/apr-util
249 statically like the older support programs.
250 [Eric Covener <covener gmail.com>]
252 *) core: Fix NONBLOCK status of listening sockets on restart/graceful
253 PR 37680. [Darius Davis <darius-abz free-range.com.au>]
255 *) mod_deflate: Rework inflate output and deflate output filter to fix several
256 issues: Incorrect handling of flush buckets, potential memory leaks,
257 excessive memory usage in inflate output filter for large compressed
258 content. PR 39854. [Ruediger Pluem, Nick Kew, Justin Erenkrantz]
260 *) mod_mem_cache: Memory leak fix: Unconditionally free the buffer.
261 [Davi Arnaut <davi haxent.com.br>]
263 *) Allow mod_dumpio to log at other than DEBUG levels via
264 the new DumpIOLogLevel directive. [Jim Jagielski]
266 *) rotatelogs: Improve error message for open failures. PR 39487.
269 *) Better detection and clean up of ldap connection that has been
270 terminated by the ldap server. PR 40878.
271 [Rob Baily <rbaily servicebench com>]
273 *) mod_mem_cache: Convert mod_mem_cache to use APR memory pool functions
274 by creating a root pool for object persistence across requests. This
275 also eliminates the need for custom serialization code.
276 [Davi Arnaut <davi haxent.com.br>]
278 *) mod_authnz_ldap: Add an AuthLDAPRemoteUserAttribute directive. If
279 set, REMOTE_USER will be set to this attribute, rather than the
280 username supplied by the user. Useful for example when you want users
281 to log in using an email address, but need to supply a userid instead
282 to the backend. [Graham Leggett]
284 *) mod_cgi and mod_cgid: Don't use apr_status_t error return
285 from input filters as HTTP return value from the handler.
288 *) mod_cache: Eliminate a bogus error in the log when a filter returns
289 AP_FILTER_ERROR. [Niklas Edmundsson <nikke acc.umu.se>]
291 *) core: Fix issue which could cause piped loggers to be orphaned and never
292 terminate after a graceful restart. PR 40651. [Joe Orton, Ruediger Pluem]
294 *) core: Fix address-in-use startup failure caused by corruption of the list
295 of listen sockets in some configurations with multiple generic Listen
296 directives. [Jeff Trawick]
298 *) mod_headers: Support regexp-based editing of HTTP headers. [Nick Kew]
300 *) mod_proxy: Add explicit flushing feature. When Servlet container sends AJP
301 body message with size 0, this means that Servlet container has asked for
302 an explicit flush. Create flush bucket in that case. This feature has been
303 added to the recent Tomcat versions without breaking the AJP protocol.
306 *) mod_proxy_balancer: Set the new environment variable BALANCER_ROUTE_CHANGED
307 if a worker with a route different from the one supplied by the client
308 had been chosen or if the client supplied no routing information for
309 a balancer with sticky sessions. [Ruediger Pluem]
311 *) mod_proxy_balancer: Add information about the route, the sticky session
312 and the worker used during a request as environment variables. PR 39806.
313 [Brian <brectanu gmail.com>]
315 *) mod_proxy: Don't try to use dead backend connection. PR 37770.
316 [Olivier BOEL <ob dorrboel.com>]
318 *) mod_proxy_balancer: Extract stickysession routing information contained as
319 parameter in the URL correctly. PR 40400.
320 [Ruediger Pluem, Tomokazu Harada <harada sysrdc.ns-sol.co.jp>]
322 *) mod_proxy_ajp: Added cping/cpong support for the AJP protocol.
323 A new worker directive ping=timeout will cause CPING packet
324 to be send expecting CPONG packet within defined timeout.
325 In case the backend is too busy this will fail instead
326 sending the full header. [Mladen Turk]
328 *) mod_cache: From RFC3986 (section 6.2.3.) if a URI contains an
329 authority component and an empty path, the empty path is to be equivalent
330 to "/". It explicitly cites the following four URIs as equivalents:
334 http://example.com:80/
335 [Davi Arnaut <davi haxent.com.br>]
337 *) mod_cache: Don't cache requests with a expires date in the past;
338 otherwise mod_cache will always try to cache the URL. This bug
339 might lead to numerous rename() errors on win32 if the URL was
340 previously cached. [Davi Arnaut <davi haxent.com.br>]
342 *) mod_disk_cache: Make sure that only positive integers are accepted
343 for the CacheMaxFileSize and CacheMinFileSize parameters in the
344 config file. PR39380. [Niklas Edmundsson <nikke acc.umu.se>]
346 *) core: Deal with the widespread use of apr_status_t return values
347 as HTTP status codes, as documented in PR#31759 (a bug shared by
348 the default handler, mod_cgi, mod_cgid, mod_proxy, and probably
349 others). PR31759. [Jeff Trawick, Ruediger Pluem, Joe Orton]
351 *) mod_ext_filter: Handle filter names which include capital letters.
352 PR 40323. [Jeff Trawick]
354 *) mod_isapi: Avoid double trailing slashes in HSE_REQ_MAP_URL_TO_PATH
355 support. Also corrects the slashes for Windows.
356 PR 15993. [William Rowe]
358 *) mod_isapi: Handle "HTTP/1.1 200 OK" style status lines correctly, the
359 token parser worked while the resulting length was misinterpreted.
360 PR 29098. [Brock Bland <bbland serena.com>]
362 *) mod_isapi: Return 0 (failure) for more of the various ap_pass_brigade
363 attempts to stream the response at the client. Log these as well.
364 PR 30022, 40470. [William Rowe, Matt Eaton <asf divinehawk.com>]
366 *) mod_isapi: Ensure we walk through all the methods the developer may have
367 employed to report their HTTP status result code.
368 PR 16637 30033 28089. [Matt Lewandowsky <matt iamcode.net>, William Rowe]
370 *) mod_echo: Fix precedence problem in if statement. PR 40658.
371 [Larry Cipriani <lvc lucent.com>]
373 *) mod_mime_magic: Fix precedence problem in if statement. PR 40656.
374 [Larry Cipriani <lvc lucent.com>]
376 *) The full server version information is now included in the error log at
377 startup as well as server status reports, irrespective of the setting
378 of the ServerTokens directive. ap_get_server_version() is now
379 deprecated, and is replaced by ap_get_server_banner() and
380 ap_get_server_description(). [Jeff Trawick]
382 *) mod_proxy_balancer: Workers can now be defined as part of
383 a balancer cluster "set" in which members of a lower-numbered set
384 are preferred over higher numbered ones. [Jim Jagielski]
386 *) mod_proxy_balancer: Workers can now be defined as "hot standby" which
387 will only be used if all other workers are unusable (eg: in
388 error or disabled). Also, the balancer-manager displays the election
389 count and I/O counts of all workers. [Jim Jagielski]
391 *) mod_proxy_ajp: Close connection to backend if reading of request body
392 fails. PR 40310. [Ian Abel <ianabel mxtelecom.com>]
394 *) mod_proxy_balancer: Retry worker chosen by route / redirect worker if
395 it is in error state before sending "Service Temporarily Unavailable".

402 handling. For some RewriteRules this could lead to a pointer being
403 written out of bounds. Reported by Mark Dowd of McAfee.
406 *) mod_authn_alias: Add a check to make sure that the base provider and the

3354 *) SECURITY: CVE-2002-0840 (cve.mitre.org)
3355 HTML-escape the address produced by ap_server_signature() against
3356 this cross-site scripting vulnerability exposed by the directive
3357 'UseCanonicalName Off'. Also HTML-escape the SERVER_NAME
3358 environment variable for CGI and SSI requests. It's safe to
3359 escape as only the '<', '>', and '&' characters are affected,
3360 which won't appear in a valid hostname. Reported by Matthew
3361 Murphy <mattmurphy kc.rr.com>. [Brian Pane]
3363 *) Fix a core dump in mod_cache when it attemtped to store uncopyable
3364 buckets. This happened, for instance, when a file to be cached
3365 contained SSI tags to execute a CGI script (passed as a pipe
3366 bucket). [Paul J. Reder]
3368 *) Ensure that output already available is flushed to the network
3369 when the content-length filter realizes that no new output will
3370 be available for a while. This helps some streaming CGIs as
3371 well as some other dynamically-generated content. [Jeff Trawick]

3482 *) The content-length filter no longer tries to buffer up
3483 the entire output of a long-running request before sending
3484 anything to the client. [Brian Pane]
3486 *) Win32: Lower the default stack size from 1MB to 256K. This will
3487 allow around 8000 threads to be started per child process.
3488 'EDITBIN /STACK:size apache.exe' can be used to change this
3489 value directly in the apache.exe executable.
3492 *) Win32: Implement ThreadLimit directive in the Windows MPM.

3545 than copying the file into the heap. [Brian Pane]
3547 *) Modified version check on openssl so that it finds the executable
3548 first and then performs a check of the version, only warning the
3549 user if they chose, or we selected, an old version of OpenSSL.
3550 This change also allows the code to work for non-openssl libraries
3551 selected via the --with-ssl=dir option, which can override the
3552 automated library check in any case. [Roy Fielding]
3554 Changes with Apache 2.0.40
3556 *) SECURITY: CVE-2002-0661 (cve.mitre.org)
3557 Close a very significant security hole that
3558 applies only to the Win32, OS2 and Netware platforms. Unix was not
3559 affected, Cygwin may be affected. Certain URIs will bypass security
3560 and allow users to invoke or access any file depending on the system
3561 configuration. Without upgrading, a single .conf change will close
3562 the vulnerability. Add the following directive in the global server
3563 httpd.conf context before any other Alias or Redirect directives;
3564 RedirectMatch 400 "\\\.\."
3565 Reported by Auriemma Luigi <bugtest sitoverde.com>.
3568 *) SECURITY: CVE-2002-0654 (cve.mitre.org)
3569 Close a path-revealing exposure in multiview type
3570 map negotiation (such as the default error documents) where the
3571 module would report the full path of the typemapped .var file when
3572 multiple documents or no documents could be served based on the mime
3573 negotiation. Reported by Auriemma Luigi <bugtest sitoverde.com>.
3576 *) SECURITY: CVE-2002-0654 (cve.mitre.org)
3577 Close a path-revealing exposure in cgi/cgid when we

3586 will be available for those that wish to work with apr-iconv.
3589 *) Fix proxy so that it is possible to access ftp: URLs via a proxy
3590 chain. [Peter Van Biesen <peter.vanbiesen vlafo.be>]
3592 *) mod-deflate now checks to make sure that 'gzip-only-text/html' is
3593 set to 1, so we can exclude things from the general case with
3594 browsermatch. [Ian Holsman, Andre Schild <A.Schild aarboard.ch>]
3596 *) Accept multiple leading /'s for requests within the DocumentRoot.
3597 PR 10946 [William Rowe, David Shane Holden <dpejesh yahoo.com>]
3599 *) Solved the reports of .pdf byterange failures on Win32 alone.
3600 APR's sendfile for the win32 platform collapses header and trailer
3601 buffers into a single buffer. However, we destroyed the pointers
3602 to the header buffer if a trailer buffer was present. PR 10781
3605 *) mod_ext_filter: Add the ability to enable or disable a filter via
3606 an environment variable. Add the ability to register a filter of
3607 type other than AP_FTYPE_RESOURCE. [Jeff Trawick]
3609 *) Restore the ability to specify host names on Listen directives.
3610 PR 11030. [Jeff Trawick, David Shane Holden <dpejesh yahoo.com>]
3612 *) When deciding on the default address family for listening sockets,
3613 make sure we can actually bind to an AF_INET6 socket before
3614 deciding that we should default to AF_INET6. This fixes a startup
3615 problem on certain levels of OpenUNIX. PR 10235. [Jeff Trawick]
3617 *) Replace usage of atol() to parse strings when we might want a
3618 larger-than-long value with apr_atoll(), which returns long long.
3619 This allows HTTPD to deal with larger files correctly.
3620 [Shantonu Sen <ssen apple.com>]
3622 *) mod_ext_filter: Ignore any content-type parameters when checking if
3623 the response should be filtered. Previously, "intype=text/html"
3624 wouldn't match something like "text/html;charset=8859_1".
3627 *) mod_ext_filter: Set up environment variables for external programs.
3628 [Craig Sebenik <craig netapp.com>]
3630 *) Modified the HTTP_IN filter to immediately append the EOS (end of
3631 stream) bucket for C-L POST bodies, saving a roundtrip and allowing
3632 the caller to determine that no content remains without prefetching
3633 additional POST body. [William Rowe]

3637 *) Look for OpenSSL libraries in /usr/lib64. [Peter Poeml <poeml suse.de>]
3639 *) Update SuSE layout. [Peter Poeml <poeml suse.de>]
3641 *) Changes to the internationalized error documents:

3643 install as simple as possible; Correct the english 500 error to
3644 be more understandable; Add a Swedish translation.
3645 [Thomas Sjogren <thomas northernsecurity.net>,
3646 Erik Abele <erik codefaktor.de>, Rich Bowen, Joshua Slive]
3648 *) Increase the limit on file descriptors per process in apachectl.

3652 and MSVC now trust that the project is current (when it is).
3653 [James Cox <imajes php.net>]
3655 *) mod_ext_filter: don't segfault if content-type is not set. PR 10617.
3656 [Arthur P. Smith <apsmith aps.org>, Jeff Trawick]
3658 *) APR-Util Renames pending have been completed [Thom May]
3660 *) Performance improvements for the code that reads request
3661 headers (ap_rgetline_core() and related functions) [Brian Pane]
3663 *) Add a new directive: MaxMemFree. MaxMemFree makes it possible
3664 to configure the maximum amount of memory the allocators will
3665 hold on to for reuse. Anything over the MaxMemFree threshold
3666 will be free()d. This directive is useful when uncommon large
3667 peaks occur in memory usage. It should _not_ be used to mask
3668 defective modules' memory use. [Sander Striker]
3670 *) Fixed the Content-Length filter so that HTTP/1.0 requests to CGI
3671 scripts would not result in a truncated response.
3672 [Ryan Bloom, Justin Erenkrantz, Cliff Woolley]
3674 *) Add a filter_init parameter to the filter registration functions
3675 so that a filter can execute arbitrary code before the handlers
3676 are invoked. This resolves a problem where mod_include requests
3677 would incorrectly return a 304. [Justin Erenkrantz]
3679 *) Fix a long-standing bug in 2.0, CGI scripts were being called
3680 with relative paths instead of absolute paths. Apache 1.3 used
3681 absolute paths for everything except for SuExec, this brings back
3682 that standard. [Ryan Bloom]
3684 *) Fix infinite loop due to two HTTP_IN filters being present for
3685 internally redirected requests. PR 10146. [Justin Erenkrantz]
3687 *) Switch conn_rec->keepalive to an enumeration rather than a bitfield.
3690 *) Fix mod_ext_filter to look in the main server for filter definitions
3691 when running in a vhost if the filter definition is not found in
3692 the vhost. PR 10147 [Jeff Trawick]
3694 *) Support WinNT CGI invocation through ScriptInterpreterSource
3695 'registry' for script interpreter paths and names with non-ascii
3696 characters in the executable filepath. [William Rowe]
3698 *) Support the -w flag on to keep the Win32 console open on error.
3701 *) Normalize the hostname value in the request_rec to all-lowercase
3702 [Perry Harrington <pedward webcom.com>]
3704 *) Fix WinNT cgi 500 errors when QUERY_ARGS or other strings include
3705 extended characters (non US-ASCII) in non-utf8 format. This brings
3706 Win32 back into CGI/1.1 compliance, and leaves charset decoding up
3707 to the cgi application itself. [William Rowe]
3709 *) Major overhaul of mod_dav, mod_dav_fs and the experimental/cache
3710 modules to bring them up to the current apr/apr-util APIs.
3713 *) Fix segfault in mod_mem_cache most frequently observed when
3714 serving the same file to multiple clients on an MP machine.
3717 *) mod_rewrite can now set cookies (RewriteRule (.*) - [CO=name:$1:.domain])
3718 [Brian Degenhardt <bmd mp3.com>, Ian Holsman]
3720 *) Fix perchild to work with apachectl by adding -k support to perchild.
3721 PR 10074 [Jeff Trawick]
3723 *) Fix a silly htpasswd.c logic error that incorrectly reported that
3724 both -c and -n had been used. PR 9989 [Cliff Woolley]
3726 *) Fixed a mod_include error case in which no HTTP response was sent
3727 to the client if an shtml document contained an unterminated SSI
3728 directive [Brian Pane]
3730 *) Improve ap_get_client_block implementation by using APR-util brigade
3731 helper functions and relying on current filter assumptions.
3734 Changes with Apache 2.0.39
3736 *) Fixed a build problem in htpasswd.c on Win32.
3737 [Guenter Knauf <eflash gmx.net>, Cliff Woolley]
3739 Changes with Apache 2.0.38
3741 *) Rewrite htpasswd to use APR. The removes the annoying warning about
3742 tmpnam being unsafe. [Ryan Bloom]
3744 *) We must set the MIME-type for .shtml files to text/html if we want them
3745 to be parsed for SSI tags. Add the config for that to the default
3746 config file so that it is easier to enable .shtml parsing.
3747 [Dave Dyer <ddyer real-me.net>]
3749 *) Fixed a problem with 'make install' on ReliantUnix.
3750 [Jean-frederic Clere <jfrederic.clere fujitsu-siemens.com>]
3752 *) Make the default_handler catch all requests that aren't served by
3753 another handler. This also gets us to return a 404 if a directory
3754 is requested, there is no DirectoryIndex, and mod_autoindex isn't
3755 loaded. [Justin Erenkrantz]
3757 *) Fixed the handling of nested if-statements in shtml files.
3758 PR 9866 [Brian Pane]
3760 *) Allow 'make install DESTDIR=/path'. This allows packagers to install
3761 into a directory different from the one that was configured. This
3762 also mirrors the root= feature from 1.3. We cannot use prefix=,
3763 because both APR and APR-util resolve their installation paths at
3764 configuration time. This means that there is no variable prefix
3765 to replace. [Andreas Hasenack <andreas netbank.com.br>]
3767 *) AIX 4.3.2 and above: Define SINGLE_LISTEN_UNSERIALIZED_ACCEPT.
3768 These levels of AIX don't have a thundering herd problem with
3769 accept(). [Jeff Trawick]
3771 *) prefork MPM: Ignore mutex errors during graceful restart. For
3772 certain types of mutexes (particularly SysV semaphores), we
3773 should expect to occasionally fail to obtain or release the
3774 mutex during restart processing. [Jeff Trawick]
3776 *) Fix install-bindist.sh so that it finds any perl instead of just
3777 early perl 5.x versions. This is consistent with a build/install
3778 from source, and it allows the perl scripts installed by a bindist
3779 to work on systems with perl 5.6. [Jeff Trawick]
3781 *) Fix apxs so that the makefile created by "apxs -g" works on AIX and
3782 Tru64 (and probably some other platforms). [Jeff Trawick]
3784 *) Allow CGI scripts to return their Content-Length. This also fixes a
3785 hang on HEAD requests seen on certain platforms (such as FreeBSD).
3788 *) Added log rotation based on file size to the RotateLog support
3789 utility. [Brad Nicholes]
3791 *) Fix some casting in mod_rewrite which broke random maps.

3800 *) 'SSLOptions +OptRengotiate' will use client cert in from the ssl
3801 session cache when there is no cert chain in the cache. prior to
3802 the fix this situation would result in a FORBIDDEN response and

3824 *) Fix apxs to allow "apxs -q installbuilddir" and to allow
3825 querying certain other variables from config_vars.mk. PR 9316
3828 *) Added the "detached" attribute to the cgi_exec_info_t internals
3829 so that Win32 and Netware won't create a new window or console
3830 for each CGI invoked. PR 8387
3831 [Brad Nicholes, William Rowe]

3847 it has sent an EOS bucket up the stack, if so, it will only ever
3848 send an EOS bucket for this request.
3849 [Ryan Bloom, Justin Erenkrantz, Greg Stein]
3851 *) Remove all special mod_ssl URIs. This also fixes the bug where
3852 redirecting (.*) will allow an SSL protected page to be viewed
3853 without SSL. [Ryan Bloom]
3855 *) Fix the binary build install script so that the build logic
3856 created by "apxs -g" will work when the user has a binary
3857 build. [Jeff Trawick]
3859 *) Allow instdso.sh to work with full paths to the shared module.
3862 *) NetWare: Enabled CGI functionality and added mod_cgi as a built
3863 in module for NetWare [Brad Nicholes]
3865 *) Changed cgi and piped log behavior to accept 65536 characters
3866 on Win32 (matching Linux) before deadlocking between outputing
3867 client stdin, slurping the output from stdout and then the stderr
3868 stream. PR 8179 [William Rowe]

4142 explicitly tell the server that warning messages should be sent
4143 to the client in addition to being recorded in the error log.
4144 Prior to this change, ap_log_rerror() always sent warning
4145 messages to the client. In one case, a faulty CGI script caused
4146 the server to send a warning message to the client that contained
4147 the full path to the CGI script. This could be considered a
4148 minor security exposure. [Bill Stoddard]

4277 -DNO_DETACH except that it doesn't switch session ids).
4280 *) Added support for Posix semaphore mutex locking (AcceptMutex posixsem)

4372 all Apache and Autoconf path variables (like --sysconfdir,
4373 --sbindir, etc). exp_foo is the "expanded" version, which means
4374 that all internal variable references have been interpolated.

4469 transmitting the last buffer (set by ProxyIOBufferSize) to the
4470 client. This prevents the backend server from being forced to hang
4471 around while the last few bytes are transmitted to a slow client.
4472 Fix the case where no error checking was performed on the final
4473 brigade in the loop. [Graham Leggett]
4475 *) Scrap CacheMaxExpireMin and CacheDefaultExpireMin. Change
4476 CacheMaxExpire and CacheDefaultExpire to use seconds rather than
4477 hours. [Graham Leggett, Bill Stoddard]
4479 *) New Directive SSIUndefinedEcho. to change the '(none)' echoed
4480 for a undefined variable. [Ian Holsman]
4482 *) Proxy HTTP and CONNECT: Keep trying other addresses from the DNS
4483 when we can't get a socket in the specified address family. We may
4484 have gotten back an IPv6 address first and yet our system is not
4485 configured to allow IPv6 sockets. [Jeff Trawick]
4487 *) Be more careful about recursively removing CVS directories. Make
4488 sure that we aren't cd'ing to their home directory first. PR: 9993
4489 [Aaron Bannert, James LewisMoss <dres lewismoss.net>]
4491 *) Add a missing errordir entry in the Debian config.layout. PR: 10067
4492 [Dirk-Jan Faber <dirk-jan selwerd.nl>, Aaron Bannert,
4493 Thom May <thom planetarytramp.net>]
4495 *) Rename the filter ordering priorities. The recent filtering fixes
4496 have showcased problems with their usage. Therefore, we need to
4497 rename them to increase the clarity. (CONTENT->RESOURCE,
4498 HTTP_HEADER->CONTENT_SET/PROTOCOL) [Justin Erenkrantz]
4500 Changes with Apache 2.0.33
4502 *) Fix a problem in the new --enable-layout functionality where
4503 it wouldn't allow overrides from variables like --prefix,
4504 --bindir, etc. [Thom May <thom planetarytramp.net>]
4506 *) Fix a bug in the core input filter for AP_MODE_EXHAUSTIVE. It
4507 no longer hangs around waiting for the socket to close before
4508 returning exhaustive data. [Aaron Bannert]
4510 *) rename apr_exploded_time_t to apr_time_exp_t (as per renames pending)
4511 [Thom May <thom planetarytramp.net>]
4513 *) Change mod_ssl to always do a full startup/teardown on restarts.
4514 this allows mod_ssl to be added to a server that is already
4515 running and makes it possible to add/change certs/keys after the
4516 server has been started. [Doug MacEachern]
4518 *) Introduce PassPhraseDialog "|/path/to/pipe" mechanism to mod_ssl.
4519 This pipe must be a bidirectional 'console' style relay, which
4520 mod_ssl prints all prompts to the pipe's stdin, and reads the
4521 passphrases from the pipe's stdout. [William Rowe]
4523 *) Fix bug where --sysconfdir and --localstatedir were being
4524 ignored. [Thom May <thom planetarytramp.net>, Aaron Bannert]
4527 *) Fix --enable-layout to work again. Caution: When specifying
4528 --enable-layout, common arguments like --prefix, --exec-prefix,
4529 etc. will be ignored and the settings from the layout will be
4530 used instead. [Thom May <thom planetarytramp.net>, Aaron Bannert]
4533 *) New Directive for mod_proxy: ProxyRemoteMatch. This provides
4534 regex pattern matching for the determination of which requests
4535 to use the remote proxy for. [Jim Jagielski]
4537 *) Fix CustomLog bytes-sent with HTTP 0.9. [Justin Erenkrantz]
4539 *) Prevent Apache from ignoring SIGHUP due to some lingering 1.3
4540 cruft in piped logs and rewritemap child processes.
4543 *) All instances of apr_lock_t have been removed and converted
4544 to one of the following new lock APIs: apr_thread_mutex.h,
4545 apr_proc_mutex.h, or apr_global_mutex.h. No new code should
4546 use the apr_lock.h API, as the old API will soon be deprecated.
4549 *) Merged in changes to mod_ssl up through 2.8.7-1.3.23.
4550 [Ralf S. Engelschall, Cliff Woolley]
4552 *) mod-include: make it handle flush'es and fix the 'false-alarm'
4553 [Justin Erenkrantz, Brian Pane, Ian Holsman]
4555 *) ap_get_*_filter_handle() functions to allow 3rd party modules
4556 to lookup filter handles so they can bypass the filter name
4557 lookup when adding filters to a request (via ap_add_*_filter_handle())
4558 [Ryan Morgan <rmorgan covalent.net>]
4560 *) Fix for multiple file buckets on Win32, where the first file
4561 bucket would cause the immediate closure of the socket on any
4562 non-keepalive requests. [Ryan Morgan <rmorgan covalent.net>]
4564 *) Correct Win32 failure of mmap of a segment beyond start of the
4565 file; fixes large SSL and similar transfers. [William Rowe]
4568 *) Implement apr_proc_detach changes and allow -DNO_DETACH in the
4569 multi-process mode to not "daemonize" while detaching from the
4570 controlling terminal. This is necessary for Apache to work with
4571 process-management tools like AIX's "System Resource Controller"
4572 as well as Dan Bernstein's "daemontools".
4573 [Jos Backus <josb cncdsl.com>, Aaron Bannert]
4575 *) Convert mod_auth_digest to use the new apr_global_mutex_t
4576 type. [Aaron Bannert]
4578 *) fix bug in mod-include where it wouldn't send a unmatched
4579 part if it was at the end of a bucket [Ian Holsman]
4581 *) worker MPM: Improve logging of errors with the interface between
4582 the listener thread and worker threads. [Jeff Trawick]
4584 *) Some browsers ignore cookies that have been merged into a
4585 single Set-Cookie header. Set-Cookie and Set-Cookie2 headers
4586 are now unmerged in the http proxy before being sent to the
4587 client. [Graham Leggett]
4589 *) Fix a problem with proxy where each entry of a duplicated
4590 header such as Set-Cookie would overwrite and obliterate the
4591 previous value of the header, resulting in multiple header
4592 values (like cookies) going missing.
4593 [Graham Leggett, Joshua Slive]
4595 *) Add the server-limit and thread-limit values to the scoreboard
4596 for the sake of third-party applications.
4597 [Adam Sussman <myddryn vishnu.vidya.com>]
4599 *) Fix segfault when proxy recieves an invalid HTTP response [Ian Holsman]
4601 *) OS/390: Get make install to properly copy DSO modules.
4604 *) Win32: Fix bug in mod_status with displaying "Restart Time"
4605 and "Server uptime".
4608 *) Fix IPv6 name-based virtual hosts. [Jeff Trawick]
4610 *) Introduce AddOutputFilterByType directive. [Justin Erenkrantz]
4612 *) Fix DEBUG_CGI support in mod_cgi. PR 9670, 9671.
4613 [David MacKenzie <djm pix.net>]
4615 *) Fix incorrect check for script_in in mod_cgi. PR 9669.
4616 [David MacKenzie <djm pix.net>]
4618 *) Fix segfault and display error when SSLMutex file can not be
4619 created. [Adam Sussman <myddryn vishnu.vidya.com>]
4621 *) Add reference counting to mod_mem_cache cache objects to
4622 better manage removing objects from the cache.
4625 *) Change the verbage on the ScoreBoardFile in our default configs.
4626 Also change the default to be commented out (unspecified) so we
4627 get anonymous shared memory by default. [Aaron Bannert]
4629 *) Implement new ScoreBoardFile directive logic. This affects how
4630 we create the scoreboard's shared memory segment. If the directive
4631 is present, a name-based segment is created. If the directive is
4632 not present, first an anonymous segment is created, and if that
4633 fails, a name-based segment is created from a file of the name
4634 DEFAULT_SCOREBOARD. This gives third-party applications the
4635 ability to access our scoreboard. [Aaron Bannert]
4637 *) Allow mod_deflate to work with non-GET requests and properly send
4638 Content-Lengths. [Sander Striker <striker apache.org>]
4640 *) Fix ap_directory_merge() to correctly merge configs when there is
4641 no <Directory /> block. [Justin Erenkrantz, William Rowe]
4643 *) Remove spurious debug messsages that are normal under HTTP
4644 keep-alive logic. [Jeff Trawick, Justin Erenkrantz]
4646 *) Fix a bug in mod_cgid that would prevent proper shutdown death
4647 of the cgid process. [Aaron Bannert]
4649 *) Add signal handling back in to the worker MPM for the one_process
4650 (-X, -DDEBUG, -DONE_PROCESS) case. [Aaron Bannert]
4652 *) Performance: Reuse per-connection transaction pools in the
4653 worker MPM, rather than destroying and recreating them. [Brian Pane]
4655 *) Remove all signals from the worker MPM's child process. Instead,
4656 the parent uses the Pipe of Death for all communication with the
4657 child processes. [Ryan Bloom]
4659 Changes with Apache 2.0.32
4661 *) mod_negotiation: ForceLanguagePriority now uses 'Prefer' as the
4662 default if the directive is not specified. This mirrors older
4663 behavior without changes to the httpd.conf. [William Rowe]
4665 *) Win32: solve the win32 service problems in 2.0.31-alpha, by fixing
4666 the service, mpm and logging code, and bugs in apr_file_open_stderr
4667 and apr_file_dup2 functions. Win2K/XP services have no handles
4668 associated for stdin/out/err, which caused unpredictable behavior
4669 in the prior release. [William Rowe, Bill Stoddard]
4671 *) Win32: simplify the Application Event Log messages, since there isn't
4672 likely to be 'more information in the error log' before an error log
4673 has been opened. [William Rowe]
4675 *) Win32: substantial cleanup to the mpm_winnt code for legibility and
4676 to follow the program flow of other MPMs. [Ryan Bloom, William Rowe]
4678 *) Win32: apache -k shutdown now behaves like apache -k stop.
4681 *) Fix prefork to not kill the parent if a child hits a resource shortage
4682 on accept(). [Greg Ames]
4684 *) Fix seg faults that occur when what should be the httpd request line
4685 starts with \r\n followed by garbage. [Greg Ames]
4687 *) Allow statically linked support binaries with the new
4688 --enable-static-support flag, and enable this behavior in
4689 the binbuild script. Also add a new --enable-static-htdbm
4690 flag. [Aaron Bannert]
4692 *) Allow mod_autoindex to serve symlinks if permitted and attempt to
4693 do only one stat() call when generating the directory listings.
4696 *) Fix resolve_symlink to save the original symlink name if known.
4699 *) Be a bit more sane with regard to CanonicalNames. If the user has
4700 specified they want to use the CanonicalName, but they have not
4701 configured a port with the ServerName, then use the same port that
4702 the original request used. [Ryan Bloom and Ken Coar]
4704 *) In core_input_filter, check for an empty brigade after
4705 APR_BRIGADE_NORMALIZE(). Otherwise, we can get segfaults if a
4706 client says it will post some data but we get FIN before any
4707 data arrives. [Jeff Trawick]
4709 *) Not being able to bind to the socket is a fatal error. We should
4710 print an error to the console, and return a non-zero status code.
4711 With these changes, all of the Unix MPMs do that correctly.
4714 *) suexec: Allow HTTPS and SSL_* environment variables to be passed
4715 through to CGI scripts. PR 9163
4716 [Brian Reid <breid customlogic.com>,
4717 Zvi Har'El <rl math.technion.ac.il>]
4719 *) binbuild.sh: Make sure that we use the expat from our source
4720 tree so that there aren't any surprises on the target machine.
4723 *) mod_cgid: Add retry logic for when the daemon can't fork fast
4724 enough to keep up with new requests. Start using
4725 HTTP_SERVER_UNAVAILABLE instead of HTTP_INTERNAL_SERVER_ERROR
4726 when we can't talk to the daemon. [Jeff Trawick]
4728 *) apxs: LTFLAGS envvar can override default libtool options. Try
4729 "LTFLAGS=' ' apxs -c mod_foo.c" to see what libtool does under
4730 the covers. [Jeff Trawick]
4732 *) The Location: response header field, used for external
4733 redirect, *must* be an absoluteURI. The Redirect directive
4734 tested for that, but RedirectMatch didn't -- it would allow
4735 almost anything through. Now it will try to turn an abs_path
4736 into an absoluteURI, but it will correctly varf like Redirect
4737 if the final redirection target isn't an absoluteURI. [Ken Coar]
4739 Changes with Apache 2.0.31
4741 *) Create the scoreboard (in the parent) in a global pool context,
4742 so it survives graceful restarts. This fixes a SEGV during
4743 graceful restarts. [Aaron Bannert]
4745 *) Add a timeout option to the proxy code 'ProxyTimeout'
4748 *) FTP directory listings are now always retrieved in ASCII mode.
4749 The FTP proxy properly escapes URI's and HTML in the generated
4750 listing, and escapes the path components when talking to the FTP
4751 server. It is now possible to browse the root directory by using
4752 a url like: ftp://user@host/%2f/ (ported from apache_1.3.24)
4753 Also, the last path component may contain wildcard characters
4754 '*' and '?', and if they do, a directory listing is created instead
4755 of a file retrieval. Example: ftp://user@host/httpd/server/*.c
4758 *) Added single-listener unserialized accept support to the
4759 worker MPM [Brian Pane]
4761 *) New Directive for mod_proxy: 'ProxyPreserveHost'. This passes
4762 the incoming host header through to the proxied server
4763 [Geoff <g.russell ieee.org>]
4765 *) New Directive Option for ProxyPass. It now can block a location
4766 from being proxied [Jukka Pihl <jukka.pihl entirem.com>]
4768 *) Don't let the default handler try to serve a raw directory. At
4769 best you get gibberish. Much worse things can happen depending
4770 on the OS. [Jeff Trawick]
4772 *) Change the pre_config hook to return a value. Modules can now emit
4773 an error message and then cause the server to quit gracefully during
4774 startup. This required a bump to the MMN. [Aaron Bannert]
4776 *) Fix some unix socket descriptor leaks in the handler side of
4777 mod_cgid (the part that runs in the server process). Whack a
4778 silly "close(-1)" in the handler too. [Jeff Trawick]
4780 *) Change the pre_mpm hook to return a value, so that scoreboard
4781 init errors percolate up to code that knows how to exit
4782 cleanly. This required a bump to the MMN. [Jeff Trawick]
4784 *) Add the socket back to the conn_rec and remove the create_connection
4785 hook. The create_connection hook had a design flaw that did not
4786 allow creating connections based on vhost info. [Bill Stoddard]
4788 *) Fixed PATH_INFO and QUERY_STRING from mod_negotiation results.
4789 Resolves the common case of using negotation to resolve the request
4790 /script/foo for /script.cgi/foo. [William Rowe]
4792 *) Added new functions ap_add_(input|output)_filter_handle to
4793 allow modules to bypass the usual filter name lookup when
4794 adding hard-coded filters to a request [Brian Pane]
4796 *) caching should now work on subrequests (still very experimental)
4799 *) The Win32 mpm_winnt now has a shared scoreboard. [William Rowe]
4801 *) Change ap_get_brigade prototype to use apr_off_t instead of apr_off_t*.
4804 *) Refactor ap_rgetline so that it does not use an internal brigade.
4805 Change ap_rgetline's prototype to return errors. [Justin Erenkrantz]
4807 *) Remove mod_auth_db. [Justin Erenkrantz]
4809 *) Do not install unnecessary pcre headers like config.h and internal.h.
4810 [Joe Orton <joe manyfish.co.uk>]
4812 *) Change in quick_hanlder behavior for subrequests. it now passes DONE
4813 (as it does for a normal request). quick_handled sub-requests now work
4814 in mod-include [Ian Holsman]
4816 *) Change SUBREQ_CORE so that it is a 'HTTP_HEADER' filter instead of
4817 'CONTENT' one, as it needs to run AFTER all content headers
4819 *) Rename BeOS MPM directive RequestsPerThread to MaxRequestsPerThread.
4822 *) Split out blocking from the mode in the input filters.
4825 *) Fix a segfault in mod_include. [Justin Erenkrantz, Jeff Trawick]
4827 *) Cause Win32 to capture all child-worker process errors in
4828 Apache to the main server error log, until the child can
4829 open its own error logs. [William Rowe]
4831 *) HPUX 11.*: Do not kill the child process when accept()
4832 returns ENOBUFS on HPUX 11.*. (ported from th 1.3 patch)
4833 [Madhusudan Mathihalli <madhusudan_mathihalli hp.com>, Bill Stoddard]
4835 *) Fix a problem in the parsing of the <Proxy foo> directive.
4838 *) rewrite of mod_ssl input filter for better performance and less
4839 memory usage [Doug MacEachern]
4841 *) allow quick_handler to be run on subrequests. [Ian Holsman]
4843 *) mod_dav now asks its provider to place content directly into the
4844 filter stack when handling a GET request. The mod_dav/provider
4845 API has changed, so providers need to be updated. [Greg Stein]
4847 *) Clear the output socket descriptor in unixd_accept() to make sure
4848 we don't supply a bogus socket to the caller if the accept fails.
4849 This caused problems with the worker MPM, which tried to process
4850 the returned socket if it was non-NULL. [Brian Pane]
4852 *) Move a check for an empty brigade to the start of core input filter
4853 to avoid segfaults. [Justin Erenkrantz, Jeff Trawick]
4855 *) Add FileETag directive to allow configurable control of what
4856 data are used to form ETag values for file-based URIs. MMN
4857 bumped to 20020111 because of fields added to the end of
4858 the core_dir_config structure. [Ken Coar]
4860 *) Fix a segfault in mod_rewrite's logging code caused by passing the
4861 wrong config to ap_get_remote_host(). [Jeff Trawick]
4863 *) Allow mod_cgid to work from a binary distribution install by
4864 using 755 for the permissions on the log directory instead of
4867 *) Fixed a segfault that happened during graceful shutdown (or when
4868 the httpd ran out of file descriptors) with the worker MPM [Brian Pane]
4870 *) Split all Win32 modules [excluding the core components mod_core,
4871 mod_so, mod_win32 and the winnt mpm] into individual loadable
4872 modules, so the administrator may individually disable the former
4873 compiled-in modules by simply commenting out their LoadModule
4874 directives. [William Rowe]
4876 *) Saved Win32 module authors and porters many future headaches, by
4877 duplicating the appropriate .h files such as os.h into the include
4878 directory, including in the build tree. [William Rowe]
4880 *) mod_ssl adjustments to help with using toolkits other than OpenSSL:
4881 Use SSL functions/macros instead of directly dereferencing SSL
4882 structures wherever possible.
4883 Add type-casts for the cases where functions return a generic pointer.
4884 Add $SSL/include to configure search path.
4885 [Madhusudan Mathihalli <madhusudan_mathihalli hp.com>]
4887 *) Moved several pointers out of the shared Scoreboard so it is
4888 more portable, and will present the vhost name across server
4889 generation restarts. [William Rowe]
4891 *) Fix SSLPassPhraseDialog exec: and SSLRandomSeed exec:
4894 Changes with Apache 2.0.30
4896 *) Fix the main bug for FreeBSD and threaded MPM's. There are
4897 still issues (see STATUS) but at least the server will now
4898 run without crashing the machine.
4899 [David Reid, Aaron Bannert, Justin Erenkrantz]
4901 *) Fix a typo in mod_deflate's m4 config section.
4902 [albert chin <china thewrittenword.com>]
4904 *) Fix a couple of mod_proxy problems forwarding HTTP connections
4905 and handling CONNECT:
4906 (1) PR #9190 Proxy failed to connect to IPv6 hosts.
4907 (2) Proxy failed to connect when the first IP address returned by
4908 the resolver was unreachable but a secondary IP address was.
4911 *) Fix the module identifer as shown in the docs for various core
4912 modules (e.g., the identifer for mod_log_config was previously
4913 listed as config_log_module). PR #9338
4914 [James Watson <ap2bug sowega.org>]
4916 *) Fix LimitRequestBody directive by placing it in the HTTP
4917 filter. [Justin Erenkrantz]
4919 *) Fix mod_proxy seg fault when the proxied server returns
4920 an HTTP/0.9 response or a bogus status line.
4923 *) Prevent mod_proxy from truncating one character off the
4924 end of the status line returned from the proxied server.
4925 [Adam Sussman, Bill Stoddard]
4927 *) Eliminate loop in ap_proxy_string_read().
4928 [Adam Sussman, Bill Stoddard]
4930 *) Provide $0..$9 results from mod_include regex parsing.
4933 *) Allow mod-include to look for alternate start & end tags [Ian Holsman]
4935 *) Introduced the ForceLanguagePriority directive, to prevent
4936 returning MULTIPLE_CHOICES or NONE_ACCEPTABLE in some cases,
4937 when using Multiviews. [William Rowe]
4939 *) Fix a problem which prevented mod_cgid and suexec from working
4940 together reliably [Greg Ames]
4942 *) Remove the call to exit() from within mod_auth_digest's post_config
4943 phase. [Aaron Bannert]
4945 *) Fix a problem in mod_auth_digest that could potentially cause
4946 problems with initialized static data on a system that uses DSOs.
4949 *) Fix a segfault in the worker MPM that could happen during
4950 child process exits. [Brian Pane, Aaron Bannert]
4952 *) Allow mod_auth_dbm to handle multiple DBM types [Ian Holsman]
4954 *) Fix matching of vhosts by ip address so we find IPv4
4955 vhost address when target address is v4-mapped form of
4956 that address. [Jeff Trawick]
4958 *) More performance tweaks to the BNDM string-search algorithm
4959 used to find "<!--#" tokens in mod_include [Brian Pane]
4961 *) Miscellaneous small performance fixes: optimized away various
4962 string copy operations and removed large temp buffers from
4963 the stack [Brian Pane]
4965 *) Fixed startup segfault that occurred when a VirtualHost
4966 directive had a port but no address [Brian Pane]
4968 *) Allow htdbm to work with multiple DBM types [Ian Holsman]
4970 *) Win32: Made change to apr_sendfile() to return APR_ENOTIMPL
4971 if oslevel < WINNT. This should fix several problems reported
4972 Against 2.0.28 on Windows 98 [Bill Stoddard]
4974 *) Win32: Fix bug that could cause CGI scripts with QUERY_STRINGS
4975 to fail. [Bill Stoddard]
4977 *) Change core code to allow an MPM to set hard thread/server
4978 limits at startup. prefork, worker, and perchild MPMs now have
4979 directives to set these limits. [Jeff Trawick]
4981 *) Win32: The async AcceptEx() event should be autoreset upon
4982 successful completion of a wait (WaitForSingleObject). This
4983 eliminates a number of spurious
4984 setsockopt(SO_UPDATE_ACCEPT_CONTEXT) failed." messages.
4987 *) Move any load library path environment variables out of
4988 apachectl and into a separate environment variable file which
4989 can be more easily tailored by the admin. The environment
4990 variable file as built by Apache may have additional system-
4991 specific settings. For example, on OS/390 we tailor the heap
4992 settings to allow lots of threads. [Jeff Trawick]
4994 *) Use the new APR pool code to reduce pool-related lock
4995 contention in the worker MPM. [Sander Striker]
4997 *) The POD no longer assumes the child is listening on 127.0.0.1
4998 and now pulls the first hostname in the list of listeners to
4999 perform the dummy connect on. This fixes a bug when the user
5000 had configured the Listen directive for an IP other than
5001 127.0.0.1. This would result in undead children and error
5002 messages such as "Connection refused: connect to listener".
5005 *) The worker MPM now respects the LockFile setting, needed to
5006 avoid locking problems with NFS. [Jeff Trawick]
5008 *) Fix segfault when worker MPM receives SIGHUP.
5009 [Ian Holsman, Aaron Bannert, Justin Erenkrantz]
5011 *) Fix bug that could potentially prevent the perchild MPM from
5012 working with more than one vhost/uid. [Aaron Bannert]
5014 *) Change make install and apxs -i processing of DSO modules to
5015 perform special handling on platforms where libtool doesn't install
5016 mod_foo.so. This fixes some wonkiness on HP-UX, Tru64, and AIX
5017 which prevented standard LoadModule statements from working.
5020 *) Whenever mod_so is enabled (not just when there are DSOs for
5021 our modules), do whatever special magic is required for compiling/
5022 loading third-party modules. This allows third-party DSOs to
5023 be used on an AIX build when there were no built-in modules
5024 built as DSOs. (This should help on OS/390 and BeOS as well.)
5027 *) Allow apxs to be used to build DSOs on AIX without requiring the
5028 user to hard-code the list of import files. (This should help
5029 on OS/390 and BeOS as well.) [Jeff Trawick]

5067 *) Fix the cmd command for mod_include. When we are processing
5068 a cmd command, we do not want to use the r->filename to set
5069 the command name. The command comes from the SSI tag. To do this,
5070 I added a variable to the function that builds the command line
5071 in mod_cgi. This allows the include_cmd function to specify
5072 the command line itself. [Ryan Bloom]

5117 *) Get mod_cgid killed when a MPM exits due to a fatal error.
5120 *) Fix a file descriptor leak in mod_include. When we include a
5121 file, we use a sub-request, but we didn't destroy the sub-request
5122 immediately, instead we waited until the original request was
5123 done. This patch closes the sub-request as soon as the data is
5124 done being generated. [Brian Pane <bpane pacbell.net>]
5126 *) Allow modules that add sockets to the ap_listeners list to
5127 define the function that should be used to accept on that
5128 socket. Each MPM can define their own function to use for
5129 the accept function with the MPM_ACCEPT_FUNC macro. This
5130 also abstracts out all of the Unix accept error handling
5131 logic, which has become out of synch across Unix MPMs.
5134 *) Fix a bug which would cause the response headers to be omitted
5135 when sending a negotiated ErrorDocument because the required
5136 filters were attached to the wrong request_rec.
5137 [John Sterling <sterling covalent.net>]
5139 *) Remove commas from the end of the macros that define
5140 directives that are used by MPMs. Prior to this patch,
5141 you would use these macros without commas, which was unlike
5142 the macros for any other directives. Now, the caller provides
5143 the comma rather than the macro providing it. This makes
5144 the macros look more like the rest of the directives.
5145 [Ryan Bloom and Cliff Woolley]
5147 *) Add 'redirect-carefully' environment option to disable sending
5148 redirects under special circumstances. This is helpful for
5149 Microsoft's WebFolders when accessing a directory resource via
5150 DAV methods. [Justin Erenkrantz]
5152 *) Begin to abstract out the underlying transport layer.
5153 The first step is to remove the socket from the conn_rec,
5154 the server now lives in a context that is passed to the
5155 core's input and output filters. This forces us to be very
5156 careful when adding calls that use the socket directly,
5157 because the socket isn't available in most locations.
5160 *) Really reset the MaxClients value in worker and threaded

5178 *) Fix infinite loop in mod_cgid.c.
5179 [Dale Ghent <daleg elemental.org>, Brian Pane <bpane pacbell.net>]
5181 *) When no port is given in a "ServerName host" directive, the
5182 server_rec->port is now set to zero, not 80. That allows for
5183 run-time deduction of the correct server port (depending on
5184 SSL/plain, and depending also on the current setting of
5185 UseCanonicalName). This change makes redirections
5186 work, even with https:// connections. As in Apache-1.3, the
5187 connection's actual port number is never used, only the ServerName
5188 setting or the client's Host: setting. Documentation updated
5189 to reflect the change. [Martin Kraemer]
5191 *) Add a '%{note-name}e' argument to mod-headers, which works in
5192 the same way as mod_log_confg. [Ian Holsman]
5194 *) Fix the spelling of the AP_MPMQ_MIN_SPARE_DAEMONS and
5195 AP_MPMQ_MAX_REQUESTS_DAEMON macros in ap_mpm.h and all standard

5206 *) Introduce an Apache mod_ssl initial configuration template
5207 (ssl.conf, generated from ssl-std.conf). [Ralf S. Engelschall]
5209 *) Fixed a memory leak in the getline parsing code that could
5210 be triggered by arbitrarily large header lines. Requests
5211 from the core input filter for single lines are now limited
5212 to HUGE_STRING_LEN (8192 bytes). [Aaron Bannert]
5214 *) Fix a truncation bug in how we print the port on the Via: header.
5215 The routine that prints the Via: header now takes a length for
5216 the port string. [Zvi Har'El <rl math.technion.ac.il>]
5218 *) Some syntax errors in mod_mime_magic's magic file can result
5219 in a 500 error, which previously was unlogged. Now we log the
5220 error. [Jeff Trawick]
5222 *) Add the support/checkgid helper app, which checks the run-time
5223 validity of group identifiers usable in the Group directive.
5226 *) Various --enable-so options have been fixed: --enable-so is
5227 treated as "static"; explicit --enable-so=shared issues an error;
5228 and explicit --enable-so fails with error on systems without
5229 APR_HAS_DSO. [Aaron Bannert]
5231 *) Fix a segfault in the core input filter when the client socket
5232 gets disconnected unexpectedly. [Cliff Woolley]
5234 *) Fix the reporting for child processes that die. This removes
5235 all of the non-portable W* macros from Apache.
5236 [Jeff Trawick and Ryan Bloom]
5238 *) Win32: Track and display "Parent Server Generation:" in
5239 mod_status output. The generation will be bumped at
5240 server graceful restart, when the child process exits
5241 by hitting MaxRequestsPerChild or if the child
5242 process exits abnormally. [Bill Stoddard]
5244 *) Win32: Fix problem where MaxRequestsPerChild directive was
5245 not being picked up in favor of the default. Enable
5246 the parent to start up a new child process immediately upon
5247 the old child starting shutdown.
5250 *) Fix some bungling of the remote port in rfc1413.c so that
5251 IdentityCheck retrieves the proper user id instead of failing
5252 and thus always returning "nobody."
5253 [Dick Streefland <Dick.Streefland xs4all.nl>]
5255 *) Introduced thread saftey for mod_rewrite's internal cache.
5256 [Brian Pane <bpane pacbell.net>]
5258 *) Simplified mod_env's directives to behave as most directives are
5259 expected, in that UnsetEnv will not unset a SetEnv and PassEnv
5260 directive following that UnsetEnv within the same container.
5261 Also provides a runtime startup warning if a PassEnv configured
5262 environment value is undefined. [William Rowe]
5264 *) The worker MPM is now completely ported to APR's new lock API. It
5265 uses native APR types for thread mutexes, cross-process mutexes,
5266 and condition variables. [Aaron Bannert]
5268 *) Sync up documentation to remove all references to the now deprecated
5269 Port directive. [Justin Erenkrantz]
5271 *) Moved all ldap modules from the core to httpd-ldap sub-project
5274 *) Exit when we can't listen on any of the configured ports. This
5275 is the same behavior as 1.3, and it avoids having the MPMs to
5276 deal with bogus ap_listen_rec structures. [Jeff Trawick]
5278 *) Cleanup the proxy code that creates a request to the origin
5279 server. This change adds an optional hook, which allows modules
5280 to gain control while the request is created if the proxy module
5281 is loaded. The purpose of this hook is to allow modules to add
5282 input and/or output filters to the request to the origin. While
5283 I was at it, I made the core use this hook, so that proxy request
5284 creation uses some of the code from the core. This can still be
5285 greatly improved, but this is a good start. [Ryan Bloom]
5287 Changes with Apache 2.0.26
5289 *) Port the MaxClients changes from the worker MPM to the threaded
5292 *) Fix mod_proxy so that it handles chunked transfer-encoding and works
5293 with the new input filtering system. [Justin Erenkrantz]
5295 *) Introduce the MultiviewsMatch directive, to allow the operator
5296 to be flexible in recognizing Handlers and Filters filename
5297 extensions as part of the Multiviews matching logic, strict with
5298 MultiviewsMatch NegotiatedOnly to accept only filename extentions
5299 that designate negotiated parameters, (content type, charset, etc.)
5300 or MultiviewsAll for the 1.3 behavior of matching any files, even
5301 if they have unregistered extensions. [William Rowe]
5303 *) Fixed the configure script to add a LoadModule directive to
5304 the default httpd.conf for any module that was compiled
5305 as a DSO. [Aaron Bannert <aaron clove.org>]
5307 *) rewrite mod_ssl input filtering to work with the new input filtering
5308 system. [Justin Erenkrantz]
5310 *) prefork: Don't segfault when we are able to listen on some but
5311 not all of the configured ports. [Jeff Trawick]
5313 *) Build mod_so even if no core modules are built shared.
5314 [Aaron Bannert <aaron clove.org>]
5316 *) Introduce ap_directory_walk rewrite (with further optimizations
5317 required) to adapt to the ap_process_request_internal() changes.
5318 Optimized so subrequests and redirects now reuse previous section
5319 merges, until we mismatch with the original directory_walk, and
5320 precomputed r->finfo results will cause directory_walk to skip
5321 the most expensive phases of the function. [William Rowe]
5323 *) Allow ApacheMonitor to connect to and control Apache on other
5324 WinNT/2K machines. [Mladen Turk <mturk mappingsoft.com>]
5326 *) Remove the Port directive. In it's place, the Listen directive
5327 is now a required directive, which tells Apache what port to
5328 listen on. The ServerName directive has also been extended
5329 to accept an optional port. If the port is specified to the
5330 ServerName, the server will report that port whenever it
5331 reports the port that it is listening on. This change was
5332 made to ease configuration errors that stem from having a Port
5333 directive, and a Listen directive. In that situation, the server
5334 would only listen to the port specified by the Listen command,
5335 which caused a lot of confusion to users. [Ryan Bloom]
5337 *) Added mod_mime_magic, mod_unique_id and mod_vhost_alias to the Win32
5338 build, as loadable modules. [William Rowe]
5340 *) Fix --enable-mods-shared processing. If most is specified,
5341 then all modules that can be compiled as shared modules are.
5342 [Aaron Bannert <aaron clove.org>]
5344 *) Update the mime.types file to map video/vnd.mpegurl to mxu
5345 and add commonly used audio/x-mpegurl for m3u extensions.
5346 [Heiko Recktenwald <uzs106 uni-bonn.de>, Lars Eilebrecht]
5348 *) Eliminate the depreciated r->content_language, in favor of the array
5349 r->content_languages introduced many years ago. Module authors must
5350 substantially overhaul their modules, so this needs to be upgraded
5351 if the module still relied on backwards-brokeness. [William Rowe]
5353 *) Allow configure help strings to work with autoconf 2.50+ and 2.13.
5356 *) Rewrite the input filtering mechanisms to consolidate and reorganize
5357 code. In short, core_input_filter does something now and
5358 ap_http_filter is now only concerned with HTTP. [Justin Erenkrantz]
5360 *) Update the Win32 build to re-absorb mod_proxy and family.
5363 *) Resolved the build failure on Win32 using MSVC 5.0 (without the
5364 current SDK.) [William Rowe]
5366 *) Some style changes to the code that does ProxyErrorOverride. Fixed
5367 config merge behaviour. [Graham Leggett]
5369 *) Allow support programs to be compiled against a static version
5370 of libapr. This allows the smaller support programs to be
5371 relocated. [Aaron Bannert <aaron clove.org>]
5373 *) Update the mime.types file to the registered media types as
5374 of 2001-09-25, and add mapping for xsl extension [Mark Cox]
5376 *) Fix MaxClients in the Worker MPM, so that it specifies the maximum
5377 number of clients that can connect at the same time, instead of
5378 specifying the maximum number of child processes.
5379 [Aaron Bannert <aaron clove.org>]
5381 *) Switch proc_pthread AcceptMutex configuration directive to pthread to
5382 be consistent with 1.3. [Justin Erenkrantz]
5384 *) Cache apr_explode_localtime() value for 15 seconds.
5385 [Brian Pane <bpane pacbell.net>]
5387 *) Fix mod_include to not return ETag or Last-Modified headers.
5388 [Ian Holsman <ianh cnet.com>]
5390 *) Fix worker MPM's scoreboard logic. [Aaron Bannert <aaron clove.org>]
5392 *) Eliminate the wasteful run-time conversion of method names from strings
5393 to numbers in places where the methods are known at compile time.
5394 [Brian Pane <bpane pacbell.net>]
5396 *) Turn the worker MPM's queue into a LIFO. This may
5397 improve cache-hit performance under some conditions.
5398 [Aaron Bannert <aaron clove.org>]
5400 *) Switch back to SIGUSR1 for graceful restarts on all platforms that
5401 support it. [Justin Erenkrantz]
5403 *) Cleanup the worker MPM. We no longer re-use transaction
5404 pools. This incurs less overhead than shuffling the pools
5405 around so that they can be re-used. Remove one of the
5406 queue's condition variables. We just redefined the API to
5407 state that you can't try to add more stuff than you allocated
5408 segments for. [Aaron Bannert <aaron clove.org>]
5410 *) Fix SSL VPATH builds [Cody Sherr <csherr covalent.net>]
5412 *) Fixed persistent connections when a request contains a body.
5415 *) mod_dav uses a new API to speak to the backend provider for dead
5416 property management. [Greg Stein]
5418 *) Remove the Win32 script-processing exception from mod_cgi, and
5419 roll build_command_line/build_argv_list into a unified, overrideable
5420 ap_cgi_build_command optional function. [William Rowe]
5422 *) Rewrite find_start_sequence to use a better search algorithm
5423 to find the start tag. [Justin Erenkrantz]
5425 *) Fix a seg fault in mod_include. When we are generating an
5426 internal redirect, we must set r->uri to "", not a bogus
5427 string, and not NULL. [Ryan Bloom]
5429 *) Optimized location_walk, so subrequests, redirects and second passes
5430 now reuse previous section merges on a <Location > by <Location >
5431 basis, until we mismatch with the original location_walk.
5434 *) Back out the 1.45 change to util_script.c. This change made
5435 us set the environment variable REQUEST_URI to the redirected
5436 URI, instead of the originally requested URI.
5437 [Taketo Kabe <kabe sra-tohoku.co.jp>]
5439 *) Make mod_include do lazy evaluation of potentially expensive to
5440 compute variables. [Brian Pane <bpane pacbell.net>]
5442 *) Fix logging of bytes sent for HEAD requests. %b and %B should
5443 log either - or 0, before this patch, they were both logging
5444 the file size. [Taketo Kabe <kabe sra-tohoku.co.jp>]
5446 *) Make mod_include check for BYTE_CHECK_THRESHOLD per bucket rather
5447 than per character. [Brian Pane <bpane pacbell.net>]
5449 *) Normalize the primary request, redirects and sub-requests to
5450 run the same ap_process_request_internal for consistency in
5451 robustness, behavior and security. [William Rowe]
5453 *) Fix a segfault with mod_include when r->path_info is not set
5454 (which is the case with mod_proxy). [Ian Holsman <ianh cnet.com>]
5456 *) Add -X functionality back. This indicates to all MPMs and any other
5457 part of Apache that it should run in "debug" mode. [Justin Erenkrantz]
5459 *) Some initial support for the cygwin platform [prefork only].
5460 This is not to be confused with support for the WinNT/Win32
5461 platform, which is the recommended configuration for native
5462 Win32 users. The cygwin platform support is recommended for
5463 cygwin platform users. [Stipe Tolj <tolj wapme-systems.de>]
5465 *) Changed syntax of Set{Input|Output}Filter. The list of filters
5466 must be semicolon delimited (if more than one filter is given.)
5467 The Set{Input|Output}Filter directive now overrides a parent
5468 container's directive (e.g. SetInputFilter in <Directory /web/foo>
5469 will override any SetInputFilter directive in <Directory /web>.)
5470 This new syntax is more consistent with Add{Input|Output}Filter
5471 directives defined in mod_mime. Also cures a bug in prior releases
5472 where the Set{Input|Output}Filter directive would corrupt the
5473 global configuration if the multiple directives were nested.
5476 *) Cured what's ailed mime for quite some time. If an AddSomething
5477 was given in the configuration (Language, Charset, Handler or
5478 Encoding) Apache would set the content type as given by AddType,
5479 but refused to check the mime.types file if AddType wasn't given
5480 for that specific extension. Setting the AddHandler for .html
5481 without setting the AddType text/html html would cause Apache to
5482 use the default content type. [William Rowe]
5484 *) Added some bulletproofing to memory allocation in the LDAP cache
5485 code. [Graham Leggett]
5487 Changes with Apache 2.0.25
5489 *) Move the installed /manual directory out of the /htdocs/ tree, so
5490 that it can be kept more independently from the remaining document
5491 root. The "Alias /manual ..." already allowed for easy projection
5492 into existing private document trees. [Martin Kraemer]
5494 *) Add specified user attributes to the environment when using
5495 mod_auth_ldap. This allows you to use mod_include to embed specified
5496 user attributes in a page like so:
5497 Hello <!--#echo var="AUTHENTICATE_CN"-->, how are you?
5500 *) Fix a performance problem with the worker MPM. We now create
5501 transaction pools once, and re-use them for each connection.
5502 [Aaron Bannert <aaron clove.org>]
5504 *) Modfied mod_mime to prevent mod_negotation from serving a multiview
5505 of a 'handler' or 'filter', so that any filename extension that does
5506 not contribute to the negotiated metadata can't be served without
5507 an explicit request. E.g., if the .Z extension is associated with
5508 an unzip filter, the user request somefile.Z.html, mod_negotiation
5509 won't serve it. It can serve somefile.Z.html when somefile.Z is
5510 requested, since the .Z extension is explictly requested, if the
5511 .html extension is associated with ContentType text/html.
5514 *) Introduce the AddInputFilter filter[;filter...] ext [ext...]
5515 and corresponding AddOutputFilter syntax, to insert one or more
5516 filters by mod_mime filename extension processing.
5519 *) Fix a growing connection pool in core_output_filter() for
5520 keepalive requests. [Jeff Trawick]
5522 *) Moved split_and_pass_pretag_buckets back to being a
5523 macro at Ryans's request. Removed the return from it
5524 by setting and returning a return code instead. Updated
5525 the code to check the return code from the macro and
5526 do the right thing. [Paul J. Reder]
5528 *) Fix a segfault when a numeric value was received for Host:.
5531 *) Add a function ap_remove_input_filter. This is to match
5532 up with ap_remove_output_filter. [Ryan Bloom]
5534 *) Clean up location_walk, so that this step performs a minimum
5535 amount of redundant effort (it must be run twice, but it will no
5536 longer reparse all <Location > blocks when the request uri
5537 hadn't changed.) [William Rowe]
5539 *) Eliminate proxy: (and all other 'special') processing from the
5540 ap_directory_walk() phase. Modules that want to use special
5541 walk logic should refer to the mod_proxy map_to_location example,
5542 with it's proxy_walk and proxysection implementation. This makes
5543 either directory_walk flavor much more legible, since that phase
5544 only runs against real <Directory > blocks.
5547 *) SECURITY: Fix a security problem in mod_include which would allow
5548 an SSI document to be passed to the client unparsed.
5549 [Cliff Woolley, Brian Pane]
5551 *) Introduce the map_to_storage hook, which allows modules to bypass
5552 the directory_walk and file_walk for non-file requests. TRACE
5553 shortcut moved to http_protocol.c as APR_HOOK_MIDDLE, and the
5554 directory_walk/file_walk happen as APR_HOOK_VERY_LAST in core.c.
5557 *) Add the ability for mod_include to add the INCLUDES filter
5558 if the file is configured for the server-parsed handler.
5559 This makes the configuration for .shtml files much easier
5560 to understand, and allows mod_include to honor Apache 1.3
5561 config files. Based on Doug MacEachern's patch to PHP
5562 to do the same thing. [Ryan Bloom]
5564 *) force OpenSSL to ignore process local-caching and to always
5565 get/set/delete sessions using mod_ssl's callbacks
5566 [Madhusudan Mathihalli <madhusudan_mathihalli hp.com>,
5567 Geoff Thorpe <geoff geoffthorpe.net>]
5569 *) Make the worker MPM shutdown and restart cleanly. This also
5570 cleans up some race conditions, and gets the worker using
5571 pools more cleanly. [Aaron Bannert <aaron clove.org>]
5573 *) Implement CRYPTO_set_locking_callback() in terms of apr_lock
5575 [Madhusudan Mathihalli <madhusudan_mathihalli hp.com>]
5577 *) Fix for mod_include. Ryan's patch to check error
5578 codes put a return in the wrong place. Also, the
5579 include handler return code wasn't being checked.
5580 I don't like macros with returns, so I converted
5581 SPLIT_AND_PASS_PRETAG_BUCKETS into a function.
5582 [Paul J. Reder <rederpj raleigh.ibm.com>]
5584 *) fix segv in mod_mime if no AddTypes are configured
5585 [John Sterling <sterling covalent.net>]
5587 *) Enable ssl client authentication at SSL_accept time
5588 [Madhusudan Mathihalli <madhusudan_mathihalli hp.com>]
5590 *) Fix a segfault in mod_include when the original request has no
5591 associated filename (e.g., we're filtering the error document for
5592 a bad URI). [Jeff Trawick]
5594 *) Fix a storage leak (a strdup() call) in mod_mime_magic. [Jeff Trawick]
5596 *) The prefork and OS/2 MPMs are overwriting the pid file when a second copy
5597 of httpd is started and shuts down due to socket conflict. Moving the
5598 call to ap_log_pid solves the problem.
5600 *) Changed the late-1.3 log_config substitution %c to %X, to log the
5601 status of the closed connection, as it conflicts with the far more
5602 common, historical ssl logging directive %...{var}c. [William Rowe]
5604 *) Added the common error/ tree to the build/install targets
5605 (similar to the common icons/ tree) for the multi-language error
5606 messages that Lars committed earlier. [William Rowe]
5608 *) Added a multi process, multi threaded OS/2 MPM mpmt_os2. [Brian Havard]
5610 *) Added a default commented-out mod_ldap and mod_auth_ldap
5611 configuration to httpd-std.conf and httpd-win.conf
5614 *) Added documentation for mod_ldap and mod_auth_ldap.
5617 *) Enabled negative caching on attribute comparisons in the LDAP cache.
5618 Fixed a problem where the default cache TTL was set in milliseconds
5619 not microseconds causing the cache to time out almost immediately.
5622 *) Fixed all the #if APR_HAS_SHARED_MEMORY checks within the LDAP
5623 module code to follow APR. [Graham Leggett]
5625 *) Fixed LDAP cleanup on graceful restarts. LDAP connections are now
5626 cleaned up when the connection pool pool is cleaned up.
5629 *) Fix a minor issue with Jeff Trawick's mod_include
5630 patch. Without this patch, the code will just allocate
5631 more bytes in get_combined_directive than are needed.
5634 *) Added the LDAP authentication module mod_auth_ldap.
5635 [Dave Carrigan <dave rudedog.org>, Graham Leggett]
5637 *) Added the LDAP cache and connection pooling module mod_ldap.
5638 [Dave Carrigan <dave rudedog.org>, Graham Leggett]
5640 *) Fix --enable-modules=all breakage with mod_auth_db and mod_auth_digest
5641 by allowing a module to disable itself if its prerequisites are not
5642 met. [Justin Erenkrantz]
5644 Changes with Apache 2.0.24
5646 *) Fix a couple of issues in mod_include when the tag appeared at
5647 offsets near 8192 in the file being parsed. [Jeff Trawick]
5649 *) Fix an assertion failure in mod_ssl when the keepalive timeout is
5650 reached. [Jeff Trawick]
5652 *) Numerous improvements to the Win32 build system. Introduced command line
5653 builds without requiring .mak files for MSVC 6.0 and later versions.
5654 Improved .dsp file compatibility for both Visual Studio 5.0 and 6.0 users.
5657 *) Assorted corrections and improvements to the winnt_mpm startup code. Better
5658 reporting of uninstalled services and other error conditions, and changed the
5659 default service name to Apache2. [William Rowe]
5661 *) Numerous improvements to the Win32 ApacheMonitor utility, including winnt_mpm
5662 compatibility with existing Apache 1.3 Win32 Apache management utilites.
5663 [Mladen Turk <mturk mappingsoft.com>, William Rowe]
5665 *) Fixed the segfaults in mod_mime introduced by hash tables in 2.0.20.
5666 [William Rowe, Greg Ames]
5668 *) Rounded out the mod_mime Add/Remove pairs by adding RemoveLanguage
5669 and RemoveCharset directives. [William Rowe]
5671 *) The Unix MPMs other than perchild now allow child server
5672 processes to use the accept mutex when starting as root and
5673 using SysV sems for the accept mutex. Previously, this
5674 combination would lead to fatal errors in the child server
5675 processes. perchild can't use SysV sems because of security
5676 issues. [Jeff Trawick, Greg Ames]
5678 *) Added Win32 revision stamp resources to all http binaries
5679 (including modules/ and support/ tools.) PR7322 [William Rowe]
5681 *) Fix ap_rvprintf to support more than 4K of data at one time.
5682 [Cody Sherr <csherr covalent.net>]
5684 *) We have always used the obsolete/deprecated Netscape syntax
5685 for our tracking cookies; now the CookieStyle directive
5686 allows the Webmaster to choose the Netscape, RFC2109, or
5687 RFC2965 format. The new CookieDomain directive allows the
5688 setting of the cookie's Domain= attribute, too. PR #s 5006,
5689 5023, 5920, 6140 [Ken Coar]
5691 *) Tweak server/Makefile so that the rules for generating exports.c
5692 are compatible with make utilities which don't expand wildcards
5693 in a dependency list (e.g., OS/390 make, certain levels of GNU
5694 make). [Jeff Trawick]
5696 *) Install the SSL headers. [John Sterling <sterling covalent.net>]
5698 *) Begin to sanitize the MPM configuration directives. Now, all
5699 MPMs use the same functions for all common MPM directives. This
5700 should make it easier to catch all bugs in these directives once.
5701 [Cody Sherr <csherr covalent.net>]
5703 *) Close a major resource leak. Every time we had issued a
5704 graceful restart, we leaked a socket descriptor.
5707 *) Fix a problem with the new method code. We need to cast
5708 the 1 to an apr_int64_t or it will be treated as a 32-bit
5709 integer, and it will wrap after being shifted 32 times.
5710 [Cody Sherr <csherr covalent.net> and Ryan Morgan <rmorgan covalent.net>]
5712 *) Fix a bug in mod_expires. Previous to this patch, if you
5713 told mod_expires to add 604800 seconds to the last-modified
5714 time, it actually added 604800 usec's to the last-modified time,
5715 so that when looking at the response it looked like nothing
5716 had been done. The root of the problem was that we always compute
5717 time in usec's, but we ask users to input sec's. This means we
5718 need to convert to usec's before using those values.
5721 *) The worker MPM now handles shutdown and restart requests. It
5722 definitely isn't perfect, but we do stop the servers correctly.
5723 The biggest problem right now is that SIGHUP causes the server to
5724 just die. [Ryan Bloom]
5726 Changes with Apache 2.0.23
5728 *) Use the prefork MPM by default on Unix. [various]
5730 *) Added a systray icon monitor application for Win32.
5731 [Mladen Turk <mturk mappingsoft.com>]
5733 *) mod_rewrite: Fix the line ending on some non-Unix systems for
5734 messages written to the rewrite log.
5735 [Richard Labennett <rlabenn us.ibm.com>]
5737 *) All mod_autoindex query parsing is now quietly quashed with the
5738 IndexOption IgnoreClient. The IndexOption SuppressColumnSorting
5739 still drops the column sort <a href>'s for the column headers, but
5740 IgnoreClient is required to ignore these Query options entirely.
5743 *) Introduced new mod_autoindex query argument parsing for F=[0|1|2]
5744 to allow the client to select plain, FancyIndexing or HTMLTable
5745 formatting, V=[0|1] to inhibit or enable version sorting, and
5746 P=pattern to return only specific files. The old Query Arguments
5747 were reorganized as C=f for sorting column 'f' (same N, D, S, or M
5748 as before), and O=A|D for ordering ascending or descending.
5751 *) Fixed an error in mod_include's directive parsing routines which
5752 caused #if, #elif, and #else expressions containing backslashes
5753 to be improperly evaluated. [Cliff Woolley]
5755 *) Introduced new mod_autoindex IndexOptions flags: SuppressIcon to
5756 drop the icon column, SuppressRules to drop the <hr> elements,
5757 and HTMLTable to create rudimentary HTML table listings (implies
5758 FancyIndexing). [William Rowe]
5760 *) Re-introduced the mod_autoindex IndexOptions flag TrackModified
5761 from Apache 1.3.15. This is needed for two reasons, first, given
5762 multiple machines within a server farm, ETags and Last-Modified
5763 stamps won't correspond from machine to machine, and second, many
5764 Unixes don't capture changes to the date or time stamp of existing
5765 files, since these don't modify the dirent itself. [William Rowe]
5767 *) Re-introduced the mod_autoindex IndexOptions flag FoldersFirst
5768 and DirectoryWidth options from Apache 1.3.10.
5769 [William Rowe, Ken Coar]
5771 *) Eliminated FancyIndexing directive, deprecated early in Apache
5772 1.3 by the IndexOptions FancyIndexing syntax. [William Rowe]
5774 *) mod_autoindex now excludes any file names that would result in
5775 an error, other than a success or redirect. Also optimized
5776 the parent directory, always included except in the URI '/'.
5779 *) Refactored mod_negotiation and mod_mime to help mod_dir accept
5780 negotiated index pages, and prevent the server from defaulting
5781 to an autoindex of the directory. mod_negotiation will now die
5782 with a 500 Internal Error if it could match some filenames
5783 (e.g. for mod_dir) but none can be served. mod_negotation now
5784 refuses to serve any file with an extention that mod_mime doesn't
5785 recognize, and wasn't part of the request. [William Rowe]
5787 *) Eliminate mod_cgi's handling of .exe files without the .exe file
5788 extension. This is already handled by multiviews, if the admin
5789 wishes to AddHandler .exe or define a content type handler and
5790 associate .exe files with that content type. Multiviews must be
5791 enabled to allow these to be served. [William Rowe]
5793 *) Speed up the server's response to a spike in incoming workload
5794 or restarts by assigning empty scoreboard slots to new processes
5795 when they are available. [Greg Ames]
5797 *) Add a handler to mod_includes.c. This handler is designed to
5798 implement the XbitHack directive. This can't be done with a
5799 fixup, because we need to check the content-type, which is
5800 only available in the handler phase. [Ryan Bloom]
5802 *) Make the includes filter check return codes from filters lower in
5803 the filter chain. If a lower level filter returns an error, then
5804 the request needs to stop immediately. This allows mod_include to
5805 stop parsing data once a lower filter recognizes an error.
5808 *) Add the ability to extend the methods that Apache understands
5809 and have those methods <limit>able in the httpd.conf. It uses
5810 the same bit mask/shifted offset as the original HTTP methods
5811 such as M_GET or M_POST, but expands the total bits from an int to
5812 an ap_int64_t to handle more bits for new request methods than
5813 an int provides. [Cody Sherr <csherr covalent.net>]
5815 *) Fix broken mod_mime behavior in merging its arguments. Possible
5816 cause of unexplicable crashes introduced in 2.0.20. [William Rowe]
5818 *) Solve many mod_ssl porting issues (too many to detail) with
5819 help from the whole team, but most notably [Ralf S. Engelschall,
5820 Madhusudan Mathihalli <madhusudan_mathihalli hp.com>,
5821 Doug MacEachern, William Rowe, Cliff Woolley]
5823 *) More stall fixes for the threaded & worker mpm's.
5824 Make mod_status output more accurate. Don't
5825 count workers in processes which aren't actively
5826 serving requests. [Greg Ames]
5828 *) Win32: Get SSI exec cgi tag working. [Bill Stoddard]
5830 *) Add a single listener/multiple worker MPM. This MPM is
5831 definately not fully correct, but it allows us to solve many
5832 of the problems that exist in the threaded MPM. This is a
5833 modified version of the threaded MPM. [Ryan Bloom]
5835 *) Improve content generation throughout Apache, providing closer
5836 compliance with HTML 3.2, HTML 4.01 Transitional and XHTML 1.0
5837 Transitional specifications. [William Rowe]
5839 Changes with Apache 2.0.22
5841 *) Fix a problem where the threaded MPM stalls after restarts or
5842 segfaults. Also prevent multiple active processes from using
5843 the same scoreboard slot. [Greg Ames]
5845 *) Apache/Win32 now fills in the service description with Apache's
5846 server version string, including loaded and advertised modules.
5849 *) Improved support for the Win32 build, to recover gracefully from
5850 missing apr or apr-util directories or the awk interpreter,
5851 create the proper cgi-bin examples, including a test-cgi.bat, and
5852 fix the perl shebang line for printenv.pl, when installing from
5853 the build environment. [William Rowe]
5855 *) Fix a segfault in threaded.c caused by passing uninitialized
5856 apr_thread_t * to apr_thread_join(). [Jeff Trawick]
5858 *) Use new APR number conversion functions to reduce CPU consumption
5859 when setting the content length, and in mod_log_config.
5862 *) Fix problem reported by Taketo Kabe <kabe sra-tohoku.co.jp>
5863 where HEAD response headers were being repeated twice for
5864 files greater than 32K bytes (4*AP_MIN_BYTES_TO_WRITE). This
5865 problem in the http_header filter was exposed by the recent rewrite
5866 of the content_length filter. [Taketo Kabe, Bill Stoddard]
5868 *) Fix seg faults in mod_status with ExtendedStatus enabled, after
5869 restarts. A garbage pointer to a vhost's server_rec from the
5870 previous generation was being left around under certain
5871 conditions. [Greg Ames]
5873 *) Fix a cosmetic problem with mod_include. Non-existant SSI vars
5874 used to appear as '(none', without the closing paren.
5875 [Günter Knauf <eflash gmx.net>]
5877 *) Improve the exports generating awk script. In the past, we had
5878 work around problems in the awk script by avoiding some #if and
5879 #ifdefs. This has bitten us many times in generating the exports.c
5880 file. This improvement allows corrects the header file parsing.
5881 [Sander Striker <striker apache.org>]
5883 Changes with Apache 2.0.21
5885 *) Resolve the Win32 htpasswd bug, where a file that existed would be
5886 overwritten, regardless of the -c flag.
5887 [William Rowe, Mladen Turk <mladen.turk mail.inet.hr>]
5889 *) Introduce connection sub-pools into ab. Truncating the lifetime
5890 of these allocations means that ab no longer perpetually grows
5891 its working set, running out of memory on large request attempts.
5894 *) Make scoreboard creation a hook. This allows management
5895 modules to have access to the scoreboard at the time that it is
5896 created, and at every restart request.
5897 [Cody Sherr <csherr covalent.net>]
5899 *) Changed AP_MPMQ_MAX_DAEMONS to refer to MaxClients and
5900 added an AP_MPMQ_MAX_DAEMON_USED to refer to the highest
5901 daemon index actually used in the scoreboard. I also
5902 updated the pertinent calls. [Paul J. Reder]
5904 *) Win32: Prevent listening sockets from being inherited by
5905 the Apache child process, CGI scripts, rotatelog process
5906 etc. If the Apache child process segfaults, any processes
5907 that the child started are not reaped. Prior to this fix,
5908 these processes inherited the listening sockets which sometimes
5909 prevented the restarted Apache child process from accepting
5910 connections (ie, the server would hang).
5913 *) Provide vhost and request strings when ExtendedStatus is on.
5916 *) Fix some issues with the pod and prefork: check the pod *after*
5917 processing a connection so that a server processing a time-
5918 consuming request bails out as soon as practical; when the
5919 parent process wakes up a server process via connect(), use an
5920 APR timeout on the connect() so that we don't hang for a long
5921 time if there aren't server processes around to do accept().
5922 [Jeff Trawick, Greg Ames]
5924 *) Performance improvement to mod_mime.c. find_ct() in mod_mime,
5925 spends a lot of time in apr_table_get calls. Using the default
5926 httpd.conf, the tables for languages and charsets are somewhat
5927 large, so the time spent scanning them on each request is
5928 significant. Replacing the tables with hash tables provides
5929 a nice speedup. [Brian Pane <bpane pacbell.net>]
5931 *) Add two functions to allow modules to access random parts of the
5932 scoreboard. This allows modules compiled for one MPM to access the
5933 scoreboard, even if it the server was compiled for another MPM.
5934 [Harrie Hazewinkel <harrie covalent.net>]
5936 Changes with Apache 2.0.20
5938 *) Fix problem in content-length filter where the filter would
5939 buffer all the output from a CGI before sending any bytes
5940 down the filter stack to the network. This problem would cause
5941 significant memory consumption if the CGIs generated
5942 lots of bytes. [Bill Stoddard]
5944 *) Get non-blocking CGI pipe reads working with the bucket brigades.
5947 *) Fix seg fault on Windows when serving files cached with mod_file_cache.
5950 *) Fix a bug in the threaded MPM that would cause it to kill off all
5951 workers immediately after starting if the number of workers started
5952 was above a certain threshold. [Ryan Bloom, Bill Stoddard]
5954 Changes with Apache 2.0.19
5956 *) Fix problem with threaded MPM. The problem was that if each child
5957 process was busy serving a single long-lived request and the server
5958 was sent a graceful restart signal, the server would stop serving
5959 requests. This would happen because each child process would wait to
5960 die until the last thread was done, and the parent wouldn't spawn any
5961 new children until a process died. Now, the parent looks at the fact
5962 that the children are dying gracefully, and starts new children.
5963 Those new children only start enough threads to compliment the number
5964 of threads in the other child process that shares the same spot in
5965 the scoreboard. In this way, we make sure to never go over
5966 MaxClients. [Ryan Bloom]
5968 *) modified mod_negotiation and mod_autoindex to speed up by almost a
5969 factor of two on apr_dir_read()-enhanced platforms, such as Win32
5970 and OS2, by calling ap_sub_request_lookup_dirent() with the results
5971 already provided by apr_dir_read(). [William Rowe]
5973 *) mod_file_cache is now more robust to filtering and serves requests
5974 slightly more efficiently. [Cliff Woolley]
5976 *) Fix problem handling FLUSH bucket in the chunked encoding filter.
5977 Module was calling ap_rwrite() followed by ap_rflush() but the
5978 served content was not being displayed in the browser. Inspection
5979 of the output stream revealed that the first data chunk was
5980 missing the trailing CRLF required by the RFC. [Bill Stoddard]
5982 *) apxs no longer generates ap_send_http_header() in the example handler
5984 *) Fix an ab problem which could cause a divide-by-zero exception
5985 with certain invocations (e.g., ab -k -c 6 -n 100 localhost/).
5986 [Ian Holsman <ianh cnet.com>]
5988 *) Solve case-insensitive platforms' confusion about negotiated
5989 filenames, allowing files of differnt case to match in choosing
5990 the document to serve. [William Rowe]
5992 *) Fix brokenness when ThreadsPerChild is higher than the built-in
5993 limit. We left ap_threads_per_child at the higher value which
5994 led to segfaults when doing certain scoreboard operations.
5997 *) Fix seg faults and/or missing output from mod_include. The
5998 default_handler was using the subrequest pool for files and
5999 MMAPs, even though the associated APR structures typically
6000 live longer than the subrequest. [Greg Ames]
6002 *) Extend mod_setenvif to support specifying regular expressions
6003 on the SetEnvIf (and SetEnvIfNoCase) directive attribute field.
6004 Example: SetEnvIf ^TS* [a-z].* HAVE_TS
6005 will cause HAVE_TS to be set if any of the request headers begins
6006 with "TS" and has a value that begins with any character in the
6007 set [a-z]. [Bill Stoddard]
6009 *) httpd children now re-bind themselves to a random CPU on
6010 multiprocessor systems on AIX via bindprocessor() in 2.0.
6011 [Victor J. Orlikowski]
6013 *) Fix htdigest. It would go into a loop in getline when adding
6014 a second user. [Bill Stoddard]
6016 *) Win32 platforms now fully support mod_userdir options. [Will Rowe]
6018 *) Automatically generate httpd.exp for AIX.
6019 DSOs now work again on AIX in 2.0
6020 [Victor J. Orlikowski]
6022 *) Add a new request hook, error_log. This phase allows modules
6023 to act on the error log string _after_ it has been written
6024 to the error log. The goal for this hook is to allow monitoring
6025 modules to send the error string to the monitoring agent.
6028 *) Modify mod_echo to make it use filters for input and output.
6029 [Ryan Morgan <rmorgan covalent.net>]
6031 *) Extend mod_headers to support conditional driven Header
6032 add, append and set. Use SetEnvIf to set an envar and conditionally
6033 add/append/set headers based on this envar thusly:
6035 SetEnvIf TSMyHeader value HAVE_TSMyHeader
6036 Header add MyHeader "%t %D" env=HAVE_TSMyHeader
6038 If the request contains header "TSMyHeader: value" then header
6039 MyHeader: "t=xxxxxxxxxx D=yyyy" will be sent on the response.
6042 *) Extend mod_headers to support using format specifiers on Header
6043 add, append and set header values. Two format specifiers are supported:
6045 %t - reports, in UTC microseconds since the epoch, when the
6046 request was received.
6048 %D - reports the time, in microseconds, between when the request was
6049 received and the response sent.
6052 Header add MyHeader "This request served in %D microseconds. %t"
6054 results in a header being added to the response that looks like this:
6056 MyHeader: This request served in D=5438 microseconds. t=991424704447256
6060 *) Fix reset_filter(). We need to be careful how we remove filters.
6061 If we set r->output_filters to NULL, we also have to reset the
6062 connection's filters. [John Sterling]
6064 *) Optimise reset_filter() in http_protocol.c. [Greg Stein]
6066 *) Add a check to ap_die() to make sure the filter stack is sane and
6067 contains the correct basic filters when an error occurs. This fixes
6068 a problem where headers are not being sent on error. [John Sterling]
6070 *) New Header directive 'echo' option. "Header echo regex" will
6071 cause any headers received on the request that match regex to be
6072 echoed to (included in) the response headers.
6075 *) include/ap_compat.h tested and set APR_COMPAT_H instead of AP_COMPAT_H.
6076 This prevented the inclusion of apr_compat.h. PR #7773
6077 [Oleg Broytmann <phd phd.pp.ru>]
6079 *) Moved util_uri to the apr-util library. This required a bunch of
6080 apr_name changes for the uri utility functions. [Justin Erenkrantz]
6082 *) Move the addition of default AP_HTTP_HTTP_HEADER filters to the
6083 insert_filter phase so that other filters are not bypassed by default.
6086 *) Reimplement mod_headers as an output filter. mod_headers can now
6087 add custom headers to inbound requests using the RequestHeader directive
6088 and to responses using the same old Header directive. [Graham Leggett]
6090 Changes with Apache 2.0.18
6092 *) Fix command-line processing so that if a bad argument is specified
6093 Apache will exit. [Jeff Trawick]
6095 *) Change the make targets and rules to be consistent in all of the
6096 Apache-owned source trees. [Roy Fielding]
6098 *) Fix processing of the TRACE method. Previously we passed bogus
6099 parms to form_header_field() and it overlaid some vhost structures,
6100 resulting in a segfault in check_hostalias().
6101 [Greg Ames, Jeff Trawick]
6103 *) Win32: Add support for reliable piped logs. If the logging process
6104 goes down, Apache will automatically restart it. This function has
6105 been part of Apache on Unix/Linux/BSD since the early v1.3 releases.
6108 *) Do not start piped log processes during the config file
6109 preflight. This change also circumvents a problem on
6110 Windows where the rotatelog processes created during preflight
6111 was not getting cleaned up properly.
6114 *) add "Request Phase Participation" info to mod_info
6117 *) Make first phase changes to the scoreboard data structures in
6118 preparation for the rewriting of the scoreboard per my posted
6119 design notes. [Paul J. Reder]
6121 *) Fix httpd's definition of LTFLAGS to be consistent with that of apr
6122 and apr-util, allow it to be overridden by the configure command-line
6123 (default="--silent") and introduce LT_LDFLAGS to replace what we were
6124 formerly abusing as LTFLAGS. [Roy Fielding]
6126 *) Clean up the reporting of incorrect closing container tags.
6127 [Barrie Slaymaker <barries slaysys.com>]
6129 *) Simplify the configure process by moving all libtool stuff to APR
6130 and moving hints.m4 inline. [Roy Fielding]
6132 *) Add the AP_DECLARE()/AP_CORE_DECLARE macros on the return types
6133 of functions used by mod_proxy for export in the DLL

6136 *) Prevent a hang when a cgi handled by mod_cgid tries to read a
6137 request body from its stdin but no reqest body is being written to
6138 the cgi. [Jeff Trawick]
6140 *) mod_log_config: %c connection status incorrectly logged
6141 as "-" (non-keepalive) when MaxKeepAliveRequests is set to 0.
6144 *) Get mod_cern_meta working under Windows
6147 *) Create Files, and thus MMAPs, out of the request pool, not the
6148 connection pool. This solves a small resource leak that had us
6149 not closing files until a connection was closed. In order to do
6150 this, at the end of the core_output_filter, we loop through the
6151 brigade and convert any data we have into a single HEAP bucket
6152 that we know will survive clearing the request_rec.
6153 [Ryan Bloom, Justin Erenkrantz <jerenkrantz ebuilt.com>,
6156 *) Completely revamp configure so that it preserves the standard make
6157 variables CPPFLAGS, CFLAGS, CXXFLAGS, LDFLAGS and LIBS by moving
6158 the configure additions to EXTRA_* variables. Also, allow the user
6159 to specify NOTEST_* values for all of the above, which eliminates the
6160 need for THREAD_CPPFLAGS, THREAD_CFLAGS, and OPTIM. Fix the setting
6161 of INCLUDES and EXTRA_INCLUDES. Check flags as they are added to
6162 avoid pointless duplications. Fix the order in which flags are given
6163 on the compile and link lines. Remove obsolete macros APR_DOEXTRA,
6164 AC_ADD_LIBRARY, AC_CHECK_DEFINE, APACHE_PASSTHRU, and APACHE_ONCE.
6165 Added APR_SAVE_THE_ENVIRONMENT and APR_RESTORE_THE_ENVIRONMENT macros.
6166 Renamed AC_TYPE_RLIM_T macro to APACHE_TYPE_RLIM_T. [Roy Fielding]
6168 *) Get mod_tls to compile/work better on Windows. PR #7612
6169 [Bernhard Schrenk <b.schrenk improx.com>]
6171 *) Fix shutdown/restart hangs in the threaded MPM.
6172 [Jeff Trawick, Greg Ames, Ryan Bloom]
6174 *) Removed the keptalive boolean from conn_rec because it is now only
6175 used by a single routine and can be replaced by a local variable.
6176 [Greg Stein, Ryan Bloom, Roy Fielding]
6178 *) Patch prefork to put enough of the signal processing back in so that
6179 signals are all handled properly now. The previous patch fixed the
6180 deadlock race condition, but broke the user directed signal handling.
6181 This fixes it to work the way it did before my previous prefork patch
6182 (primarily, SIGTERM is now working).
6184 *) Change how input filters decide how much data is returned to the
6185 higher filter. We used to use a field in the conn_rec, with this
6186 change, we use an argument to ap_get_brigade to determine how much
6187 data is retrieved. [Ryan Bloom]
6189 *) Fix seg fault at start-up introduced by Ryan's change to enable
6190 modules to specify their own logging tags. mod_log_config
6191 registers an optional function, ap_register_log_handler().
6192 ap_register_log_handler() was being called by http_core before
6193 the directive hash table was created. This patch creates the
6194 directive hash table before ap_register_log_handler() is
6195 registered as an optional function.
6196 [jean-frederic clere <jfrederic.clere fujitsu-siemens.com>]
6198 *) Add ap_set_int_slot() function
6199 [John K. Sterling <sterling covalent.net>]
6201 *) Under certain circumstances, Apache did not supply the
6202 right response headers when requiring authentication.
6203 [Gertjan van Wingerde <Gertjan.van.Wingerde cmg.nl>] PR#7114
6204 (This is a port of the change that went into Apache 1.3.19.)
6206 *) Allow modules to specify their own logging tags. This basically
6207 allows a module to tell mod_log_config that when %x is encountered
6208 a specific function should be called. Currently, x can be any single
6209 character. It may be more useful to make this a string at some point.
6212 Changes with Apache 2.0.17
6214 *) If a higher-level filter handles the byterange aspects of a
6215 request, then the byterange filter should not try to redo the
6216 work. The most common case of this happening, is a byterange
6217 request going through the proxy, and the origin server handles
6218 the byterange request. The proxy should ignore it.
6219 [Graham Leggett <minfrin sharp.fm>]
6221 *) Changed the threaded mpm to have child_main join to each of the
6222 worker threads to make sure the kids are all gone before child_main
6223 exits after a signal (cleanup from perform_idle_server_maintenance).
6224 This is an extension of Ryans recent commit to make the child_main
6227 *) Add more options to the ap_mpm_query function. This also allows MPMs to
6228 report if their threads are dynamic or static. Finally, this also
6229 implements a new API, ap_show_mpm, which returns the MPM that was
6230 required into the core. [Harrie Hazewinkel <harrie covalent.net>]
6232 *) Do not install the binaries from the support directory twice.
6233 [jun-ichiro hagino <itojun iijlab.net>]
6235 *) The ap_f* functions should flush data to the filter that is passed
6236 in, not the filter after the one passed in.
6237 [Ryan Morgan <rmorgan covalent.net>]
6239 *) Make ab work again by changing its native types to apr types and formats.
6240 [Justin Erenkrantz <jerenkrantz ebuilt.com>]
6242 *) Move the byterange filter and all of the supporting functions back
6243 to the HTTP module. The byterange filter turned out to be very
6244 HTTP specific, and it belongs in the HTTP module. [Greg Stein]
6246 *) Make clean, distclean, and extraclean consistently according to the
6247 Gnu makefile guidelines. [Justin Erenkrantz <jerenkrantz ebuilt.com>]
6249 *) Fix errors in the renaming of the apr_threadattr_detach_xxx functions.
6250 This may have been causing problems stopping processes in the threaded
6253 *) Fix content-length in mod_negotiation to a long int representation.
6256 *) Remove BindAddress from the default config file.
6257 [<giles nemeton.com.au>]
6259 *) Allow module authors to add a module to their Apache build using
6260 --with-module, without re-running buildconf. The syntax is:
6261 --with-module=module_type:/path/to/module.c
6262 The configure script will copy the module.c file to
6263 modules/module_type, and it will be added to the relevant Makefiles.
6264 currently, this only works for static modules. [Ryan Bloom]
6266 *) Changes required to make prefork clean up idle children properly.
6267 There was a window during which a starting worker deadlocks when
6268 an idle cleanup arrives before it completes init. Apache then keeps
6269 trying to cleanup the same deadlocked worker forever (until higher
6270 pids come along, but it still will never reduce below the deadlocked
6271 pid). Thus the number of children would not reduce to the correct
6272 idle level. [Paul J. Reder]
6274 Changes with Apache 2.0.16
6276 *) Change the default installation directory to /usr/local/apache2,
6277 as now defined by the "Apache" layout in config.layout. [Marc Slemko]
6279 *) OS/2: Added support for building loadable modules as OS/2 DLLs.
6282 *) Get MaxRequestsPerChild working with the Windows MPM.
6285 *) Make generic hooks to work, with mod_generic_hook_import/export
6286 experimental modules. [Ben Laurie, Will Rowe]
6288 *) Fix segfaults for configuration file syntax errors such as
6289 "<Directory>" followed by "</Directory" and
6290 "<Directory>" followed by "</Directoryz>". [Jeff Trawick]
6292 *) Cleanup the --enable-layout option of configure. This makes
6293 us use a consistent location for the config.layout file, and it
6294 makes configure more portable.
6295 [jun-ichiro hagino <itojun iijlab.net>]
6297 *) Changes to 'ab'; fixed int overrun's, added statistics, output in
6298 csv/gnuplot format, rudimentary ssl support and various other tweaks
6299 to make results more true to what is measured. The upshot of this it
6300 turns out that 'ab' has often underreported the true performance of
6301 apache. Often by a order of magnitude :-) See talk/paper of Sander
6302 Temme at April ApacheCon 2001 for details.
6303 [Dirk-Willem van Gulik]
6305 *) Clean up mod_cgid's temporary request pool. Besides fixing a
6306 storage leak this ensures that some unnecessary pipes are closed.
6309 *) Performance: Add quick_handler hook. This hook is called at the
6310 very beginning of the request processing before location_walk,
6311 translate_name, etc. This hook is useful for URI keyed content
6312 caches like Mike Abbott's Quick Shortcut Cache.
6315 *) top_module global variable renamed to ap_top_module [Perl]
6317 *) Move ap_set_last_modified to the core. This is a potentially
6318 controversial change, because this is kind of HTTP specific. However
6319 many protocols should be able to take advantage of this kind of
6320 information. I expect that headers will need one more layer of
6321 indirection for multi-protocol work, but this is a small step in
6322 the right direction. [Ryan Bloom]
6324 *) Enable mod_status by default. This matches what Apache 1.3 does.
6327 *) Add a ScriptSock directive to the default config file. This is
6328 only enabled when mod_cgid is used.
6329 [Taketo Kabe <kabe sra-tohoku.co.jp>]
6331 Changes with Apache 2.0.15
6333 *) Untangled the buildconf script and eliminated the need for build's
6334 aclocal.m4, generated_lists, build.mk, build2.mk, and a host of other
6335 libtool muck that is now under srclib/apr/build. [Roy Fielding]
6337 *) Win32: Don't accept more connections than we have worker threads
6341 *) Fix bug in the Unix threaded.c MPM that allowed child processes
6342 to fork() new child processes.
6345 *) SECURITY: Fix a major security problem with double-reverse lookup
6346 checking. Previously, a client connecting over IPv4 would not be
6347 matched properly when the server had an IPv6 listening socket.
6348 PR #7407 [Taketo Kabe <kiabe sra-tohoku.co.jp>]
6350 *) Change the way the beos MPM handles polling to allow it to stop and
6351 restart. Problem was the sockets being polled were being reset by
6352 the select call, so once it had accepted a connection it was no
6353 longer listening on the UDP socket we use for shutdown instructions.
6354 APR needs to be altered, patch on it's way. [David Reid]
6356 *) Empty out the brigade shared by ap_getline()/ap_get_client_block()
6357 on error exit from ap_getline(). Some other code got upset because
6358 the wrong data was in the brigade. [Greg Ames, Jeff Trawick]
6360 *) Handle ap_discard_request_body() being called more than once.
6361 [Greg Ames, Jeff Trawick]
6363 *) Get rid of an inadvertent close of file descriptor 2 in
6364 mod_mime_magic. [Greg Ames, Jeff Trawick]
6366 *) Add a hook, create_request. This hook allows modules to modify
6367 a request while it is being created. This hook is called for all
6368 request_rec's, main request, sub request, and internal redirect.
6369 When this hook is called, the r->main, r->prev, r->next
6370 pointers have been set, so modules can determine what kind of
6371 request this is. [Ryan Bloom]
6373 *) Cleanup the build process a bit more. The Apache configure
6374 script no longer creates its own helper scripts, it just
6376 [jean-frederic clere <jfrederic.clere fujitsu-siemens.com>]
6378 *) Stop the forced downgrade of the connection to HTTP/1.0 for
6379 proxy requests. [Graham Leggett]
6381 *) Avoid using sscanf to determine the HTTP protocol number in
6382 the common case because sscanf is a performance hog. From
6383 Mike Abbot's Accelerating Apache patch number 6.
6384 [Mike Abbot <mja trudge.engr.sgi.com>, Bill Stoddard]
6386 *) SECURITY: Fix a security exposure in mod_access. Previously when
6387 IPv6 listening sockets were used, allow/deny-from-IPv4-address rules
6388 were not evaluated properly (PR #7407). Also, add the ability to
6389 specify IPv6 address strings with optional prefix length on Allow
6390 and Deny. [Jeff Trawick]
6392 *) Enhance rotatelogs so that a UTC offset can be specified, and
6393 the logfile name can be formatted using strftime(3). (Brought
6394 forward from 1.3.) [Ken Coar]
6396 *) Reimplement the Windows MPM (mpm_winnt.c) to eliminate calling
6397 DuplicateHandle on an IOCompletionPort (a practice which
6398 MS "discourages"). The new model does not rely on associating
6399 the completion port with the listening sockets, thus the
6400 completion port can be completely managed within the child
6401 process. A dedicated thread accepts connections off the network,
6402 then calls PostQueuedCompletionStatus() to wake up worker
6403 threads blocked on the completion port.
6406 *) Bring forward the --suexec-umask option which allows the
6407 builder to preset the umask for suexec processes. [Ken Coar]
6409 *) Add a -V flag to suexec, which causes it to display the
6410 compile-time settings with which it was built. (Only
6411 usable by root or the AP_HTTPD_USER username.) [Ken Coar]
6413 *) Mod_include should always unset the content-length if the file is
6414 going to be passed through send_parsed_content. There is no to
6415 determine if the content will change before actually scanning the
6416 entire content. It is far safer to just remove the C-L as long
6417 as we are scanning it. [Ryan Bloom]
6419 *) Make sure Apache sends WWW-Authenticate during a reverse proxy
6420 request and not Proxy-Authenticate.
6421 [Graham Leggett <minfrin sharp.fm>]
6423 Changes with Apache 2.0.14
6425 *) Fix content-length computation. We ONLY compute a content-length if
6426 We are not in a 1.1 request and we cannot chunk, and this is a keepalive
6427 or we already have all the data. [Ryan Bloom]
6429 *) Report unbounded containers in the config file. Previously, a typo
6430 in the </container> directive could result in the rest of the config
6431 file being silently ignored, with undesired defaults used.
6434 *) Make the old_write filter use the ap_f* functions for the buffering.
6437 *) Move more code from the http module into the core server. This
6438 is core code, basically the default handler, the default input
6439 and output filters, and all of the core configuration directives.
6440 All of this code is required in order for the server to work, with or
6441 without HTTP. The server is closer to working without the HTTP
6442 module, although there is still more to do. [Ryan Bloom]
6444 *) Fix a number of SGI compile warnings throughout the server. Fix some
6445 bad parameters to apr_bucket_read(). Fix a bad statement in
6446 ap_method_in_list(). For the mod_rewrite cache use apr_time_t
6447 consistently; we were mixing apr_time_t and time_t in invalid ways
6448 before. In load_file(), call apr_dso_error() instead of
6449 apr_strerror() so that we get a more specific string on some platforms.
6450 PR #6980 [Jeff Trawick]
6452 *) Allow modules to query the MPM about it's execution profile. This
6453 query API can and should be extended in the future, but for now,
6454 max_daemons, and threading or forking is a very good start.
6455 [Jon Travis <jtravis covalent.net>]
6457 *) Modify mod_include to send blocks of data no larger than 9k.
6458 Without this, mod_include will wait until the whole file is parsed,
6459 or the first tag is found to send any data to the client.
6460 [Paul J. Reder <rederpj raleigh.ibm.com>]
6462 *) Fix mod_info, so that <Directory> and <Location> directives are
6463 not displayed twice when displaying the current configuration.
6464 [Ryan Morgan <rmorgan covalent.net>]
6466 *) Add config directives to override DEFAULT_ERROR_MSG and
6467 DEFAULT_TIME_FORMAT. This was sent in as PR 6193.
6468 [Dan Rench <drench xnet.com>]
6470 *) Get mod_info building and loading on Win32. [William Rowe]
6472 *) Begin to move protocol independant functions out of mod_http. The goal
6473 is to have only functions that are HTTP specific in the http directory.
6476 Changes with Apache 2.0.13
6478 *) Don't assume that there will always be multiple calls to the byterange
6479 filter. It is possible that we will need to do byteranges with only
6480 one call to the filter. [Ryan Morgan <rmorgan covalent.net>]
6482 *) Move the error_bucket definition from the http module to the
6483 core server. Every protocol will need this ability, not just
6486 Changes with Apache 2.0.12
6488 *) Modify mod_file_cache to save pre-formatted strings for
6489 content-length and last-modified headers for performance.

6492 *) Namespace protect IOBUFSIZ since it is exposed in the API.
6493 [Jon Travis <jtravis covalent.net>]

6496 says we should. [Andre Breiler <andre.breiler rd.bbc.co.uk>]
6498 *) Fix a seg fault in mod_userdir.c. We used to use the pw structure
6499 without ever filling it out. This fixes PR 7271.
6500 [Taketo Kabe <kabe sra-tohoku.co.jp> and
6501 Cliff Woolley <cliffwoolley yahoo.com>]
6503 *) Add a couple of GCC attribute tags to printf style functions.
6504 [Jon Travis <jtravis covalent.net>]
6506 *) Add the correct language tag for interoperation with the Taiwanese
6507 versions of MSIE and Netscape. [Clive Lin <clive CirX.ORG>] PR#7142
6509 *) Migrate the perchild MPM to use the new apr signal child, and
6510 APR thread functions. [Ryan Bloom]
6512 *) Close one copy of the CGI's stdout before creating the new process.
6513 The CGI will still have stdout, because we have already dup'ed it.
6514 This keeps Apache from waiting forever to send the results of a CGI
6515 process that has forked a long-lived child process.
6516 [Taketo Kabe <kabe sra-tohoku.co.jp>]
6518 *) Remove the rest of the pthreads functions from the threaded MPM.
6519 This requires the APR support for a signal thread that was just
6522 *) Make mod_dir use a fixup for sending a redirect to the browser.
6523 Before this, we were using a handler, which doesn't make much
6524 sense, because the handler wasn't generating any data, it would
6525 either return a redirect error code, or DECLINED. This fits the
6526 current hooks better. [Ryan Morgan <rmorgan covalent.net>]
6528 *) Make the threaded MPM use APR threads instead of pthreads.
6531 *) Get mod_tls to the point where it actually appears to work in all cases.
6534 *) implement --enable-modules and --enable-mods-shared for "all" and
6535 "most". [Greg Stein]
6537 *) Move the threaded MPM to use APR locks instead of pthread locks.
6540 *) Rename mpmt_pthread to threaded. This is more in line with the
6541 fact that mpmt_pthread shouldn't be using pthreads directly, and
6542 it is a smaller name that doesn't tie into anything.
6545 *) Rename the module structures so that the exported symbol matches
6546 the file name, and it is easier to automate the installation
6547 process (generating LoadModule directives from the module filenames).
6550 *) Remove the coalesce filter. With the ap_f* functions, this filter
6551 is no longer needed. [Ryan Bloom]
6553 Changes with Apache 2.0.11
6555 *) Remove the dexter MPM. Perchild is the same basic idea, but it has the
6556 added feature of allowing a uid/gid per child process. If no
6557 uid/gid is specified, then Perchild behaves exactly like dexter.
6560 *) Get perchild building again. [Ryan Bloom]
6562 *) Don't disable threads just because we are using the prefork MPM.
6563 If somebody wants to compile without threads, they must now add
6564 --disable-threads to the configure command line. [Ryan Bloom]
6566 *) Begin to move the calls to update_child_status into common code, so
6567 that each individual MPM does not need to update the scoreboard itself.
6570 *) Allow mod_tls to compile under Unix boxes where openssl has been
6571 installed to the system include files.
6572 [Gomez Henri <new-httpd slib.fr>]
6574 *) Cleanup the mod_tls configure process. This should remove any need
6575 to hand-edit any files. We require OpenSSL 0.9.6 or later, but
6576 configure doesn't check that yet. [Ryan Bloom]
6578 *) Add a very early prototype of SSL support (in mod_tls.c). It is
6579 vital that you read modules/tls/README before attempting to build
6582 *) Fix a potential seg fault on all platforms. David Reid fixed this
6583 on BEOS, but the problem could happen anywhere, so we don't want
6584 to #ifdef it. [Cliff Woolley <cliffwoolley yahoo.com>]
6586 *) Add new LogFormat directive, %D, to log time it takes to serve a
6587 request in microseconds. [Bill Stoddard]
6589 *) Change AddInputFilter and AddOutputFilter to SetInputFilter and
6590 SetOutputFilter. This corresponds nicely with the other Set
6591 directives, which operate on containers while the Add* directives
6592 tend to work directly on extensions. [Ryan Bloom]
6594 *) Cleanup the header handling a bit. This uses the apr_brigade_*
6595 functions for the buffering so that we don't need to compute
6596 the length of the headers before we actually create the header
6597 buffer. [Ryan Bloom]
6599 *) Allow filters to buffer data using the ap_f* functions. These have
6600 become macros that resolve directly to apr_brigade_*.
6603 *) Get the Unix MPM's to do a graceful restart again. If we are going
6604 to register a cleanup with ap_cleanup_scoreboard, then we have to
6605 kill the cleanup with the same function, and that function can't be
6606 static. [Ryan Bloom]
6608 *) Install all required header files. Without these, it was not
6609 possible to compile some modules outside of the server.
6612 *) Fix the AliasMatch directive in Apache 2.0. When we brought a patch
6613 forward from 1.3 to 2.0, we missed a single line, which broke regex
6614 aliases. [Ryan Bloom]
6616 *) We have a poor abstraction in the protocol. This is a temporary
6617 hack to fix the bug, but it will need to be fixed for real. If
6618 we find an error while sending out a custom error response, we back
6619 up to the first non-OK request and send the data. Then, when we send
6620 the EOS from finalize_request_protocol, we go to the last request,
6621 to ensure that we aren't sending an EOS to a request that has already
6622 received one. Because the data is sent on a different request than
6623 the EOS, the error text never gets sent down the filter stack. This
6624 fixes the problem by finding the last request, and sending the data
6625 with that request. [Ryan Bloom]
6627 *) Make the server status page show the correct restart time, and
6628 thus the proper uptime. [Ryan Bloom]
6630 *) Move the CGI creation logic from mod_include to mod_cgi(d). This
6631 should reduce the amount of duplicate code that is required to
6632 create CGI processes.
6633 [Paul J. Reder <rederpj raleigh.ibm.com>]
6635 *) ap_new_connection() closes the socket and returns NULL if a socket
6636 call fails. Usually this is due to a connection which has been
6637 reset. [Jeff Trawick]
6639 *) Move the Apache version information out of httpd.h and into release.h.
6640 This is in preparation for the first tag with the new tag and release
6641 system. [Ryan Bloom]
6643 *) Begin restructuring scoreboard code to enable adding back in
6644 the ability to use IPC other than shared memory.
6645 Get mod_status working on Windows again. [Bill Stoddard]
6647 *) Make mod_status work with 2.0. This will work for prefork,
6648 mpmt_pthread, and dexter. [Ryan Bloom]
6650 *) Correct a typo in httpd.conf.

6656 find a fully-qualified domain name at startup.
6657 PR#7170 [Danek Duvall <dduvall eng.sun.com>]
6659 *) Make mod_cgid work with SuExec. [Ryan Bloom]
6661 *) Adopt apr user/group name features for mod_rewrite. Eliminates some
6662 'extra' stat's for user/group since they should never occur, and now
6663 resolves the SCRIPT_USER and SCRIPT_GROUP, including on WinNT NTFS
6664 volumes. [William Rowe]
6666 *) Adopt apr features to simplify mod_includes. This changes the
6667 behavior of the USER_NAME variable, unknown uid's are now reported
6668 as USER_NAME="<unknown>" rather than the old user#000 result.
6669 WinNT now resolves USER_NAME on NTFS volumes. [William Rowe]
6671 *) Adopt apr features for simplifing mod_userdir, and accept the new
6672 Win32/OS2 exceptions without hiccuping. [William Rowe]
6674 *) Replace configure --with-optim option by using and saving the
6675 environment variable OPTIM instead. This is needed because configure
6676 options do not support multiple flags separated by spaces.
6679 *) Fix some byterange handling. If we get a byte range that looks like
6680 "-999999" where that is past the end of the file, we should return
6681 a PARTIAL CONTENT status code, and return the whole file as one big
6682 byterange. This matches the 1.3 handling now. [Ryan Bloom]
6684 *) Make the error bucket a real meta-data bucket. This means that the
6685 bucket length is 0, and a read returns NULL data. If one of these
6686 buckets is passed down after the headers are sent, this data will
6687 just be ignored. [Greg Stein]
6689 *) The prefork MPM wasn't killing child processes correctly if a restart
6690 signal was received while the process was serving a request. The child
6691 process would become the equivalent of a second parent process. If
6692 we break out of the accept loop, then we need to do die after cleaning
6693 up after ourselves. [Ryan Bloom]
6695 *) Change the Prefork MPM to use SIGWINCH instead of SIGUSR1 for graceful
6696 restarts. [Ryan Bloom]
6698 *) Modify the apr_stat/lstat/getfileinfo calls within apache to use
6699 the most optimal APR_FINFO_wanted bits. This spares Win32 from
6700 performing very expensive owner, group and permission lookups
6701 and allows the server to function until these apr_finfo_t fields
6702 are implemented under Win32. [William Rowe]
6704 *) Support for typedsafe optional functions - that is functions exported by
6705 optional modules, which, therefore, may or may not be present, depending
6706 on configuration. See the experimental modules mod_optional_fn_{ex,im}port
6707 for sample code. [Ben Laurie]
6709 *) filters can now report an HTTP error to the server. This is done
6710 by sending a brigade where the first bucket is an error_bucket.
6711 This bucket is a simple bucket that stores an HTTP error and
6712 a string. Currently the string is not used, but it may be needed
6713 to output an error log. The http_header_filter will find this
6714 bucket, and output the error text, and then return
6715 AP_FILTER_ERROR, which informs the server that the error web page
6716 has already been sent. [Ryan Bloom]
6718 *) If we get an error, then we should remove all filters except for
6719 those critical to serving a web page. This fixes a bug, where
6720 error pages were going through the byterange filter, even though
6721 that made no sense. [Ryan Bloom]
6723 *) Relax the syntax checking of Host: headers in order to support
6724 iDNS. PR#6635 [Tony Finch]
6726 *) Cleanup the byterange filter to use the apr_brigade_partition
6727 and apr_bucket_copy functions. This removes a lot of very messy
6728 code, and hopefully makes this filter more stable.
6731 *) Remove AddModule and ClearModuleList directives. Both of these
6732 directives were used to ensure that modules could be enabled
6733 in the correct order. That requirement is now gone, because
6734 we use hooks to ensure that modules are in the correct order.
6737 *) When SuExec is specified, we need to add it to the list of
6738 targets to be built. If we don't, then any changes to the
6739 configuration won't affect SuExec, unless 'make suexec' is
6740 specifically run. [Ryan Bloom]
6742 *) Cleaned out open_file from mod_file_cache, as apr now accepts
6743 the APR_XTHREAD argument to open a file for consumption by
6744 parallel threads on win32. [William Rowe]
6746 *) Correct a bug in determining when we follow symlinks. The code
6747 expected a stat -1 result, not an apr_status_t positive error.
6748 Also check if the APR_FINFO_USER fields are valid before we
6749 follow the link. [William Rowe]
6751 *) Move initgroupgs, ap_uname2id and ap_gname2id from util.c to
6752 mpm_common.c. These functions are only valid on some platforms,
6753 so they should not be in the main-line code. [Ryan Bloom]
6755 *) Remove ap_chdir_file(). This function is not thread-safe,
6756 and nobody is currently using it. [Ryan Bloom]
6758 *) Do not try to run make depend if there are no .c files in the
6759 current directory, doing so makes `make depend` fail.
6762 *) Update highperformance.conf to work with either prefork or
6763 pthreads mpms. [Greg Ames]
6765 *) Stop checking to see if this is a pipelined request if we know
6766 for a fact that it isn't. Basically, if r->connection->keepalive == 0.
6767 This keeps us from making an extra read call when serving a 1.0
6768 request. [Ryan Bloom and Greg Stein]
6770 *) Fix the handling of variable expansion look-ahead in mod_rewrite,
6771 i.e. syntax like %{LA-U:REMOTE_USER}, and also fix the parsing of
6772 more complicated nested RewriteMap lookups. PR#7087 [Tony Finch]
6774 *) Fix the RFC number mentioned when complaining about a missing
6775 Host: header. PR#7079 [Alexey Toptygin <alexeyt wam.umd.edu>]
6777 *) Fix an endless loop in ab which occurred when ab was posting
6778 and the server dropped the connection unexpectedly.
6781 *) Fix a segfault while handling request bodies in ap_http_filter().
6782 This problem has been seen with mod_dav usage as well as with
6783 requests where the body was just being discarded. [Jeff Trawick]
6785 *) Some adjustment on the handling and automatic setting (via
6786 hints.m4) of various compilation flags (eg: CFLAGS). Also,
6787 add the capability to specify flags (NOTEST_CFLAGS and
6788 NOTEST_LDFLAGS) which are used to compile Apache, but
6789 not used during the configuration process. Useful for
6790 flags like "-Werror". [Jim Jagielski]
6792 *) Stop using environment variables to force debug mode or
6793 no detach. We now use the -D command line argument to
6794 specify the correct mode. -DONE_PROCESS and -DNO_DETACH.
6795 [Greg Stein, Ryan Bloom]
6797 *) Change handlers to use hooks. [Ben Laurie]
6799 *) Stop returning copies of filenames from both apr_file_t and
6800 apr_dir_t. We pstrdup the filenames that we store in the
6801 actual structures, so we don't need to pstrdup the strings again.
6804 *) mod_cgi: Fix some problems where the wrong error value was being
6805 traced. [Jeff Trawick]
6807 *) EBCDIC: Fix some missing ASCII conversion on some protocol data.
6810 *) Add generic hooks. [Ben Laurie]
6812 *) Use a real pool to dup the error log descriptor. [Ryan Bloom]
6814 *) Fix a segfault caused by mod_ext_filter when the external filter
6815 program does not exist. [Jeff Trawick]
6817 *) Fix an output truncation error when on an HTTP >= 1.0 request an
6818 object of size between DEFAULT_BUCKET_SIZE and AP_MIN_BYTES_TO_WRITE
6819 was served through mod_charset_lite (or anything else that would
6820 create a transient bucket in this size range). ap_bucket_make_heap()
6821 silently failed (fixed), transient_setaside() discovered it, but
6822 ap_save_brigade() ignored it (fixed). [Jeff Trawick]
6824 *) Ignore \r\n or \n when using PEEK mode for input filters. The problem
6825 is that some browsers send extra lines at the end of POST requests, and
6826 we don't want to delay sending data back to the user just because the
6827 browser isn't well behaved. [Ryan Bloom]
6829 *) Get SuEXEC working again. We can't send absolute paths to suExec
6830 because it refuses to execute those programs. SuEXEC also wasn't
6831 always recognizing configuration changes made using the autoconf
6834 *) Allow the buildconf process to find the config.m4 files in the correct
6835 order. Basically, we can now name config.m4 files as config\d\d.m4,
6836 and we will sort them correctly when inserting them into the build
6837 process. [Ryan Bloom]
6839 *) Get mod_cgid to use apr calls for creating the actual CGI process.
6840 This also allows mod_cgid to use ap_os_create_priviledged_process,
6841 thus allowing for SuExec execution from mod_cgid. Currently, we do
6842 not support everything that standard SuExec supports, but at least
6843 it works minimally now. [Ryan Bloom]
6845 *) Allow SuExec to be configured from the ./configure command line.
6848 *) Update some of the docs in README and INSTALL to reflect some of
6849 the changes in Apache 2.0 [Cliff Woolley <cliffwoolley yahoo.com>]
6851 *) If we get EAGAIN returned from the call to apr_sendfile, then we
6852 need to call sendfile again. This gets us serving large files
6853 such as apache_2.0a9.tar.gz on FreeBSD again. [Ryan Bloom]
6855 *) Get the support programs building cleanly again.
6856 [Cliff Woolley <cliffwoolley yahoo.com>]
6858 *) The Apache/Win32 Apache.exe and dll's now live in bin. The
6859 current directory logic now backs up over bin/ to determine the
6860 server root from the Apache.exe path.
6862 *) Apache/Win32 now follows the standard conventions of mod_foo.so
6863 loadable modules, dynamic libs are all named libfoo.dll, and the
6864 makefile.win populates the include, lib and libexec directories.
6866 *) Apache is now IPv6-capable. On systems where APR supports IPv6,
6867 Apache gets IPv6 listening sockets by default. Additionally, the
6868 Listen, NameVirtualHost, and <VirtualHost> directives support IPv6
6869 numeric address strings (e.g., "Listen [fe80::1]:8080").
6872 *) Modify the install directory layout. Modules are now installed in
6873 modules/. Shared libraries should be installed in libraries/, but
6874 we don't have any of those on Unix yet. All install directories
6875 are modifyable at configure time. [Ryan Bloom]
6877 *) Install all header files in the same directory on Unix. [Ryan Bloom]
6879 *) Get the functions in server/linked into the server, regardless of
6880 which modules linked into the server. This uses the same hack
6881 for Apache that we use for APR and apr-util to ensure all of the
6882 necessary functions are linked. As a part of thise, the CHARSET_EBCDIC
6883 was renamed to AP_CHARSET_EBCDIC for namespace protection, and to make
6884 the scripts a bit easier.
6887 *) Rework the RFC1413 handling to make it thread-safe, use a timeout
6888 on the query, and remove IPv4 dependencies. [Jeff Trawick]
6890 *) Get all of the auth modules to the point that they will install and
6891 be loadable into the server. Our new build/install mechanism expects
6892 that all modules will have a common name format. The auth modules
6893 didn't use that format, so we didn't install them properly.
6896 *) API routines ap_pgethostbyname() and ap_pduphostent() are no longer
6897 available. Use apr_getaddrinfo() instead. [Jeff Trawick]
6899 *) Get "NameVirtualHost *" working in 2.0. [Ryan Bloom]
6901 *) Return HTTP_RANGE_NOT_SATISFIABLE if the every range requested starts
6902 after the end of the response. [Ryan Bloom]
6904 *) Get byterange requests working with responses that do not have a
6905 content-length. Because of the way byterange requests work, we have to
6906 have all of the data before we can actually do the byterange, so we
6907 can compute the content-length in the byterange filter.
6910 *) Get exe CGI's working again on Windows.
6913 *) Get mod_cgid and mod_rewrite to work as DSOs by changing the way
6914 they keep track of whether or not their post config hook has been
6915 called before. Instead of a static variable (which is replaced when
6916 the DSO is loaded a second time), use userdata in the process pool.
6919 Changes with Apache 2.0a9
6921 *) Win32 now requires perl to complete the final install step for users
6922 to build + install on Win32. Makefile.win now rewrites @@ServerRoot@
6923 and installs the conf, htdocs and htdocs/manual directories.
6926 *) Make mod_include use a hash table to associate directive tags with
6927 functions. This allows modules to implement their own SSI tags easily.
6928 The idea is simple enough, a module can insert it's own tag and function
6929 combination into a hash table provided by mod_include. While mod_include
6930 parses an SSI file, when it encounters a tag in the file, it does a
6931 hash lookup to find the function that implements that tag, and passes
6932 all of the relevant data to the function. That function is then
6933 responsible for processing the tag and handing the remaining data back
6934 to mod_include for further processing.
6935 [Paul J. Reder <rederpj raleigh.ibm.com>]
6937 *) Get rid of ap_new_apr_connection(). ap_new_connection() now has
6938 fewer parameters: the local and remote socket addresses were removed
6939 from the parameter list because all required information is available
6940 via the APR socket. [Jeff Trawick]
6942 *) Distribution directory structure reorganized to reflect a
6943 normal source distribution with external install targets.
6946 *) The MPMs that need multiple segments of shared memory now create
6947 two apr_shmem_t variables, one for each shared memory allocation.
6948 the problem is that we can't determine how much memory will be required
6949 for shared memory allocations once we try to allocate more than one
6950 variable. The MM code automatically aligns the shared memory allocations,
6951 so we end up needing to pad the amount of shared memory we want based
6952 on how many variables will be allocated out of the shared memory segment.
6953 It is just easier to create a second apr_shmem_t variable, and two
6954 shmem memory blocks.
6957 *) Cleanup the export list a bit. This creates a single unified list of
6958 functions exported by APR. The export list is generated at configure
6959 time, and that list is then used to generate the exports.c file.
6960 Because of the way the export list is generated, we only export those
6961 functions that are valid on the platform we are building on.
6964 *) Enable logging the cookie with mod_log_config
6965 [Sander van Zoest <sander covalent.net>]
6967 *) Fix a segfault in mod_info when it reaches the end of the configuration.
6970 *) Added lib/aputil/ as a placeholder for utility functions which are not
6971 specific to the Apache HTTP Server (but do not make sense with APR).
6972 The first utility is "apu_dbm": a set of functions to work with DBM
6973 files. This first version can be compiled for SDBM or GDBM databases.
6976 *) Complete re-write of mod_include. This makes mod_include a filter that
6977 uses buckets directly. This has now served the FAQ correctly.
6978 [Paul Reder <rederpj raleigh.ibm.com>]
6980 *) Allow modules to specify the first filter in a sub_request when
6981 making the sub_request. This keeps modules from having to change the
6982 output_filter immediately after creating the sub-request, and therefore
6983 skip the sub_req_output_filter. [Ryan Bloom]
6985 *) Update ab to accept URLs with IPv6 literal address strings (in the
6986 format described in RFC 2732), and to build Host header fields in
6987 the same format. This allows IPv6 literal address strings to be
6988 used with ab. This support has been tested against Apache 1.3 with
6989 the KAME patch, but Apache 2.0 does not yet work with this format
6990 of the Host header field. [Jeff Trawick]
6992 *) Accomodate an out-of-space condition in the piped logs and the
6993 rotatelogs.c code, and no longer churn log processes for this
6994 condition. [Victor J. Orlikowski]
6996 *) Add support for partial writes with apr_sendfile() to core_output_filter.
6999 Changes with Apache 2.0a8
7001 *) Add a directive to mod_mime so that filters can be associated with
7005 *) Get multi-views working again. We were setting the path_info
7006 field incorrectly if we couldn't find the specified file.
7009 *) Fix 304 processing. The core should never try to send the headers
7010 down the filter stack. Always, just setup the table in the request
7011 record, and let the header filter convert it to data that is ready
7015 *) More fixes for the proxy. There are still bugs in the proxy code,
7016 but this has now proxied www.yahoo.com and www.ntrnet.net (my ISP)
7020 *) Fix params for apr_getaddrinfo() call in connect proxy handler.
7023 *) APR: Add new apr_getopt_long function to handle long options.
7024 [B. W. Fitzpatrick <fitz red-bean.com>]
7026 *) APR: Change apr_connect() to take apr_sockaddr_t instead of hostname.
7027 Add generic apr_create_socket(). Add apr_getaddrinfo() for doing
7028 hostname resolution/address string parsing and building
7029 apr_sockaddr_t. Add apr_get_sockaddr() for getting the address
7030 of one of the apr_sockaddr_t structures for a socket. Change
7031 apr_bind() to take apr_sockaddr_t. [David Reid and Jeff Trawick]
7033 *) Remove the BUFF from the HTTP proxy. This is still a bit ugly, but
7034 I have proxied pages with it, cleanup will commence soon.
7037 *) Make the proxy work with filters. This isn't perfect, because we
7038 aren't dealing with the headers properly. [Ryan Bloom]
7040 *) Do not send a content-length iff the C-L is 0 and this is a head
7041 request. [Ryan Bloom]
7043 *) Make cgi-bin work as a regular directory when using mod_vhost_alias
7044 with no VirtualScriptAlias directives. PR#6829 [Tony Finch]
7046 *) Remove BUFF from the PROXY connect handling. [Ryan Bloom]
7048 *) Get the default_handler to stop trying to deal with HEAD requests.
7049 The idea is to let the content-length filter compute the C-L before
7050 we try to send the data. If we can get the C-L correctly, then we
7051 should send it in the HEAD response.
7054 *) The Header filter can now determine if a body should be sent based
7055 on r->header_only. The general idea of this is that if we delay
7056 deciding to send the body, then we might be able to compute the
7057 content-length correctly, which will help caching proxies to cache
7058 our data better. Any handler that doesn't want to try to compute
7059 the content-length can just send an EOS bucket without data and
7060 everything will just work.
7063 *) Add the referer to the error log if one is available.
7064 [Markus Gyger <mgyger itr.ch>]
7066 *) Mod_info.c has now been ported to Apache 2.0. As a part of this
7067 change, the root of the configuration tree has been exposed to modules
7069 [Ryan Morgan <rmorgan covalent.net>]
7071 *) Get the core_output_filter to use the bucket interface directly.
7072 This keeps us from calling the content-length filter multiple times
7073 for a simple static request.
7076 *) We are sending the content-type correctly now.
7077 [Ryan Bloom and Will Rowe]
7079 *) APR on FreeBSD: Fix a bug in apr_sendfile() which caused us to report
7080 a bogus bytes-sent value when the only thing being sent was trailers
7081 and writev() returned an error (or EAGAIN). [Jeff Trawick]
7083 *) Get SINGLE_LISTEN_UNSERIALIZED_ACCEPT working again. This uses the
7084 hints file to determine which platforms define
7085 SINGLE_LISTEN_UNSERIALIZED_ACCEPT.
7088 *) APR: add apr_get_home_directory() [Jeff Trawick]
7090 *) Initial import of 1.3-current mod_proxy. [Chuck Murcko]
7092 *) Not all platforms have INADDR_NONE defined by default. Apache
7093 used to make this check and define INADDR_NONE if appropriate,
7094 but APR needs the check too, and I suspect other applications will
7095 as well. APR now defines APR_INADDR_NONE, which is always a valid
7096 value on all platforms.
7097 [Branko Čibej <brane xbc.nu>]
7099 *) Destroy the pthread mutex in lock_intra_cleanup() for PR#6824.
7100 [Shuichi Kitaguchi <ki hh.iij4u.or.jp>]
7102 *) Relax the syntax checking of Host: headers in order to support
7103 iDNS. PR#6635 [Tony Finch]
7105 *) When reading from file buckets we convert to an MMAP if it makes
7106 sense. This also simplifies the default handler because the
7107 default handler no longer needs to try to create MMAPs.
7110 *) BUFF has been removed from the main server. The BUFF code will remain
7111 in the code until it has been purged from the proxy module as well.
7114 *) Byteranges have been completely re-written to be a filter. This
7115 has been tested, and I believe it is working correctly, but it could
7116 doesn't work for the Adobe Acrobat plug-in. The output almost matches
7117 the output from 1.3, the only difference being that 1.3 includes
7118 a content-length in the response, and this does not.
7121 *) APR read/write functions and bucket read functions now operate
7122 on unsigned integers, instead of signed ones. It doesn't make
7123 any sense to use signed ints, because we return the error codes,
7124 so if we have an error we should report 0 bytes read or written.
7127 *) Always compute the content length, whether it is sent or not.
7128 The reason for this, is that it allows us to correctly report
7129 the bytes_sent when logging the request. This also simplifies
7130 content-length filter a bit, and fixes the actual byte-reporing
7131 code in mod_log_config.c
7134 *) Remove AP_END_OF_BRIGADE definition. This does not signify what
7135 it says, because it was only used by EOS and FLUSH buckets. Since
7136 neither of those are required at the end of a brigade, this was
7137 really signifying FLUSH_THE_DATA, but that can be determined better
7138 by checking AP_BUCKET_IS_EOS() or AP_BUCKET_IS_FLUSH. EOS and FLUSH
7139 buckets now return a length of 0, which is actually the amount of data
7140 read, so they make more sense.
7143 *) Allow the core_output_filter to save some data past the end of a
7144 request. If we get an EOS bucket, we only send the data if it
7145 makes sense to send it. This allows us to pipeline request
7146 responses. As a part of this, we also need to allocate mmap
7147 buckets out of the connection pool, not the request pool. This
7148 allows the mmap to outlive the request.
7151 *) Make blocking and non-blocking bucket reads work correctly for
7152 sockets and pipes. These are the only bucket types that should
7153 have non-blocking reads, because the other bucket types should
7154 ALWAYS be able to return something immediately.
7157 *) In the Apache/Win32 console window, accept Ctrl+C to stop the
7158 server, but use Ctrl+Break to initiate a graceful restart
7159 instead of duplicating behavior. [John Sterling]
7161 *) Patch mod_autoindex to set the Last-Modified header based on
7162 the directory's mtime, and add the ETag header. [William Rowe]
7164 *) Merge the 1.3 patch to add support for logging query string in
7165 such a way that "%m %U%q %H" is the same as "%r".
7168 *) Port three log methods from mod_log_config 1.3 to 2.0:
7169 CLF compliant '-' byte count, method and protocol.
7172 *) Add a new LogFormat directive, %c, that will log connection
7173 status at the end of the response as follows:
7174 'X' - connection aborted before the response completed.
7175 '+' - connection may be kept-alive by the server.
7176 '-' - connection will be closed by the server.
7179 *) Expand APR for WinNT to fully accept and return utf-8 encoded
7180 Unicode file names and paths for Win32, and tag the Content-Type
7181 from mod_autoindex to reflect that charset if the feature
7182 macro APR_HAS_UNICODE_FS is true. [William Rowe]
7184 *) Compute the content length (and add appropriate header field) for
7185 the response when no content length is available and we can't use
7186 chunked encoding. [Jeff Trawick]
7188 *) Changed ap_discard_request_body() to use REQUEST_CHUNKED_DECHUNK,
7189 so that content input filters get dechunked data when using
7190 the default handler. Also removed REQUEST_CHUNKED_PASS.
7193 *) Add mod_ext_filter as an experimental module. This module allows
7194 the administrator to use external programs as filters. Currently,
7195 only filtering of output is supported. [Jeff Trawick]
7197 *) Most Apache functions work on EBCDIC machines again, as protocol
7198 data is now translated (again). [Jeff Trawick]
7200 *) Introduce ap_xlate_proto_{to|from}_ascii() to clean up some of
7201 the EBCDIC support. They are noops on ASCII machines, so this
7202 type of translation doesn't have to be surrounded by #ifdef
7203 CHARSET_EBCDIC. [Jeff Trawick]
7205 *) Fix mod_include. tag commands work again, and the server will
7206 send the FAQ again. This also allows mod_include to set aside
7207 buckets that include partial buckets.
7208 [Ryan Bloom and David Reid]
7210 *) Add suexec support back. [Manoj Kasichainula]
7212 *) Lingering close now uses the socket directly instead of using
7213 BUFF. This has been tested, but since all we can tell is that it
7214 doesn't fail, this needs to be really hacked on.
7217 *) Allow filters to modify headers and have those headers be sent to
7218 the client. The idea is that we have an http_header filter that
7219 actually sends the headers to the network. This removes the need
7220 for the BUFF to send headers.
7223 *) Charset translation: mod_charset_lite handles translation of
7224 request bodies. Get rid of the xlate version of ap_md5_digest()
7225 since we don't compute digests of filtered (e.g., translated)
7226 response bodies this way anymore. (Note that we don't do it at
7227 all at the present; somebody needs to write a filter to do so.)
7230 *) Input filters and ap_get_brigade() now have a input mode parameter
7231 (blocking, non-blocking, peek) instead of a length parameter.
7234 *) Update the mime.types file to the registered media types as
7235 of 2000-10-19. PR#6613 [Carsten Klapp <carsten.klapp home.net>,
7238 *) Namespace protect some macros declared in ap_config.h
7241 *) Support HTTP header line folding with input filtering.
7244 *) Mod_include works again. This should still be re-written, but at
7245 least now we can serve an SHTML page again.
7248 *) Begin to remove BUFF from the core. Currently, we keep a pointer
7249 to both the BUFF and the socket in the conn_rec. Functions that
7250 want to use the BUFF can, functions that want to use the socket,
7251 can. They point to the same place.
7254 *) apr_psprintf doesn't understand %lld as a format. Make it %ld.
7255 [Tomas Ögren <stric ing.umu.se>]
7257 *) APR pipes on Unix and Win32 are now cleaned up automatically when the
7258 associated pool goes away. (APR pipes on OS/2 were already had this
7259 logic.) This resolvs a fatal file descriptor leak with CGIs.
7262 *) The final line of the config file was not being read if there was
7263 no \n at the end of it. This was caused by apr_fgets returning
7264 APR_EOF even though we had read valid data. This is solved by
7265 making cfg_getline check the buff that was returned from apr_fgets.
7266 If apr_fgets return APR_EOF, but there was data in the buf, then we
7267 return the buf, otherwise we return NULL.
7270 *) Piped logs work again in the 2.0 series.
7273 *) Restore functionality broken by the mod_rewrite security fix:
7274 rewrite map lookup keys and default values are now expanded
7275 so that the lookup can depend on the requested URI etc.
7276 PR #6671 [Tony Finch]
7278 *) SECURITY: Tighten up the syntax checking of Host: headers to fix a
7279 security bug in some mass virtual hosting configurations
7280 that can allow a remote attacker to retrieve some files
7281 on the system that should be inaccessible. [Tony Finch]
7283 *) Add a pool bucket type. This bucket is used for data allocated out
7284 of a pool. If the pool is cleaned before the bucket is destroyed, then
7285 the data is converted to a heap bucket, allowing it to survive the
7289 *) Add a flush bucket. This allows modules to signal that the filters
7290 should all flush whatever data they currently have. There is no way
7291 to actually force them to do this, so if a filter ignores this bucket,
7292 that's life, but at least we can try with this.
7295 *) Add an output filter for sub-requests. This filter just strips the
7296 EOS bucket so that we don't confuse the main request's core output
7297 filter by sending multiple EOS buckets. This change also makes sub
7298 requests start to send EOS buckets when they are finished.
7301 *) Make ap_bucket_(read|destroy|split|setaside) into macros. Also
7302 makes ap_bucket_destroy a return void, which is okay because it
7303 used to always return APR_SUCCESS, and nobody ever checked its
7304 return value anyway.
7305 [Cliff Woolley <cliffwoolley yahoo.com>]
7307 *) Remove the index into the bucket-type table from the buckets
7308 structure. This has now been replaced with a pointer to the
7309 bucket_type. Also add some macros to test the bucket-type.
7312 *) Renamed all MODULE_EXPORT symbols to AP_MODULE_DECLARE and all symbols
7313 for CORE_EXPORT to AP_CORE_DECLARE (namespace protecting the wrapper)
7314 and retitled API_EXPORT as AP_DECLARE and APR_EXPORT as APR_DECLARE.
7315 All _VAR_ flavors changes to _DATA to be absolutely clear.
7318 *) Add support for /, //, //servername and //server/sharename
7319 parsing of <Directory> blocks under Win32 and OS2.
7320 [Tim Costello, William Rowe, Brian Harvard]
7322 *) Remove the function pointers from the ap_bucket type. They have been
7323 replaced with a global table. Modules are allowed to register bucket
7324 types and use then use those buckets.
7327 *) mod_cgid: In the handler, shut down the Unix socket (only for write)
7328 once we finish writing the request body to the cgi child process;
7329 otherwise, the client doesn't hit EOF on stdin. Small request bodies
7330 worked without this change (for reasons I don't understand), but large
7331 ones didn't. [Jeff Trawick]
7333 *) Remove file bucket specific information from the ap_bucket type.
7334 This has been moved to a file_bucket specific type that hangs off
7335 the data pointer in the ap_bucket type.
7338 *) Input filtering now has a third argument. This is the amount of data
7339 to read from lower filters. This argument can be -1, 0, or a positive
7340 number. -1 means give me all the data you have, I'll deal with it and
7341 let you know if I need more. 0 means give me one line and one line
7342 only. A positive number means I want no more than this much data.
7344 Currently, only 0 and a positive number are implemented. This allows
7345 us to remove the remaining field from the conn_rec structure, which
7349 *) Big cleanup of the input filtering. The goal is that http_filter
7350 understands two conditions, headers and body. It knows where it is
7351 based on c->remaining. If c->remaining is 0, then we are in headers,
7352 and http_filter returns a line at a time. If it is not 0, then we are
7353 in body, and http_filter returns raw data, but only up to c->remaining
7354 bytes. It can return less, but never more.
7355 [Greg Ames, Ryan Bloom, Jeff Trawick]
7357 *) mod_cgi: Write all of the request body to the child, not just what
7358 the kernel would accept on the first write. [Jeff Trawick]
7360 *) Back out the change that moved the brigade from the core_output_filters
7361 ctx to the conn_rec. Since all requests over a given connection
7362 go through the same core_output_filter, the ctx pointer has the
7366 *) Fix another bug in the send_the_file() read/write loop. A partial
7367 send by apr_send would cause unsent data in the read buffer to
7368 get clobbered. Complete making send_the_file handle partial
7369 writes to the network.
7372 *) Fix a couple of type fixes to allow compilation on AIX again
7373 [Victor J. Orlikowski <v.j.orlikowski gte.net>]
7375 *) Fix bug in send_the_file() which causes offset to be ignored
7376 if there are no headers to send.
7379 *) Handle APR_ENOTIMPL returned from apr_sendfile in the core
7380 filter. Useful for supporting Windows 9* with a binary
7381 compiled on Windows NT.
7384 Changes with Apache 2.0a7
7386 *) Reimplement core_output_filter to buffer/save bucket brigades
7387 across multiple calls to the core_filter. The brigade will be
7388 sent when either MIN_BYTES_TO_SEND or MAX_IOVEC_TO_WRITE
7389 thresholds are hit or the EOS bucket is received.
7392 *) Create experimental filter (buffer_filter) that coalesces bytes
7393 into one large buffer before invoking the next filter in the
7394 chain. This filter is particularly useful with the current
7395 implementation of mod_autoindex when it inserted above the
7396 chunk_filter. mod_autoindex generates a lot of brigades that
7397 containing buckets holding just a few bytes each. The
7398 buffer_filter coalesces these buckets into a single large bucket.
7401 *) Add apr_sendfile() support into the core_output_filter.
7404 *) Add apr_sendv() support into the core_output_filter.
7407 *) Fix mod_log_config so that it compiles cleanly with BUFFERED_LOGS
7408 [Mike Abbott <mja sgi.com>]
7410 *) Remove ap_send_fb. This is no longer used in Apache, and it doesn't
7411 make much sense, because Apache uses buckets instead of BUFFs now.
7414 *) send_the_file now falls back to a read/write loop on platforms that
7415 do not have sendfile.
7416 [Ryan Bloom and Brian Havard]
7418 *) Install apachectl correctly, and substitute the proper values so
7419 that it works again. [Ryan Bloom]
7421 *) Better(??) handle platforms that lack sendfile().
7424 *) APR now has UUID generation/formatting/parsing support.
7427 *) Begin the http_filter. This is an input filter that understands
7428 the absolute basic amount required to parse an HTTP Request. The
7429 goal is to be able to split headers from request body before passing
7430 the data back to the other filters.
7433 *) Bring forward from 1.3.13 the config directory implementation
7436 *) install apxs if it is created
7439 *) Added APR_IS_STATUS_condition test macros to eliminate canonical error
7440 conversions. [William Rowe]
7442 *) Now that we have ap_add_input_filter(), rename ap_add_filter() to
7443 ap_add_output_filter(). [Jeff Trawick]
7445 *) Multiple build and configuration fixes
7448 -add datadir and localstatedir substitutions
7450 -fix logfilename misspelling
7451 -fix evaluation of installation dir variables and
7452 -replace $foobar by $(foobar) to be usefull in the makefile
7456 -add rules for cross-compiling in rules.mk. Okay, rule to check for
7457 $CC_FOR_BUILD is still missing
7458 -use CHECK_TOOL instead of CHECK_PROG for ranlib
7459 -add missing "AR=@AR@" to severaly Makefile.in's
7460 -cache result for "struct rlimit"
7461 -compile all helper programs with native and cross compiler
7462 and use the native version to generate header file
7463 [Rüdiger Kuhlmann <Tadu gmx.de>]
7465 *) Prepare our autoconf setup for autoconf 2.14a and for cross-
7467 [Rüdiger Kuhlmann <Tadu gmx.de>]
7469 *) Fix a bug where a client which only sends \n to delimit header
7470 lines (netcat) gets a strange looking HTTP_NOT_IMPLEMENTED
7471 message. Start working on ebcdic co-existance with input
7473 [William Rowe, Greg Ames]
7475 *) If mod_so is enabled in the server always create libexec, even
7476 if there are no modules installed in this directory. This is a
7477 requirement for APXS to work correctly.
7480 *) Connection oriented output filters are now stored in the
7481 conn_rec instead of the request_rec. This allows us to add the
7482 output filter in the pre-connection phase instead of the
7483 post_read_request phase, which keeps us from trying to write an
7484 error page before we have a filter to write to the network.
7485 [Ryan Bloom, Jeff Trawick, and Greg Ames]
7487 *) Cleaning up an mmap bucket no longer deletes the mmap. An
7488 mmap can be used across multiple buckets (default_handler with
7489 byte ranges, mod_file_cache, mod_mmap_static), so cleanup of
7490 the mmap itself can't be associated with the bucket.
7493 *) Add .dll caching directive ISAPICacheFile to mod_isapi.
7496 *) Radical surgery to improve mod_isapi support under Win32.
7497 Includes a number of newer ServerSupportFunction calls, support
7498 for ReadClient (in order to retrieve POSTs greater than 48KB),
7499 and general bug fixes to more reliably load ISAPI .dll's and
7500 prevent leaking handle resources. Note: There are still
7501 discrepancies between IIS's and Apache's ServerVariables, and
7502 async calls are still not supported. Additional warnings are
7503 logged to facilitate debugging of unsupported ISAPI calls.
7506 *) Add input filtering to Apache. The basic idea for the input
7507 filters is the same as the ideas for output filters. The biggest
7508 difference is that instead of calling ap_pass_brigade, ap_get_brigade
7509 should be called, and the order of execution for the filter itself is
7510 different. When writing an output filter, a brigade is passed in,
7511 and filters operate directly on that brigade, when done, they call
7512 ap_pass_brigade. Input filters are the exact opposite. Because input
7513 is not a push operation, filters first call ap_get_brigade. When this
7514 function returns, the input filter will be left with a valid brigade.
7515 The input filter should then operate on the brigade, and return.
7518 *) Fix building on BSD/OS using its native make. The build system
7519 falls back to the BSD .include directive on that host platform.
7522 *) Expand dbmmanage to allow -d -m -s -p options for Crypt, MD5,
7523 SHA1 and plaintext password encodings. Make feature tests a
7524 bit more flexible. [William Rowe]
7526 *) Charset translation: mod_charset_lite handles output content
7527 translation in a filter. mod_charset_lite no longer ignores
7528 subrequests. A bunch of cruft related to BUFF's support for
7529 translating request and response bodies was removed.
7532 *) Move the addition of the CORE filter to the post_read_request
7533 hook in http_core.c. This removes the need to add the filter in
7534 multiple places and allows for an SSL module to be added much
7535 simpler. [Ryan Bloom]
7537 *) SECURITY: CVE-2000-0913 (cve.mitre.org)
7538 Fix a security problem that affects certain configurations of
7539 mod_rewrite. If the result of a RewriteRule is a filename that
7540 contains expansion specifiers, especially regexp backreferences
7541 $0..$9 and %0..%9, then it may be possible for an attacker to
7542 access any file on the web server. [Tony Finch]
7544 *) Fix a bug where errors that are detected during early request parsing
7545 don't produce visible HTTP error messages at the browser, because
7546 the core_filter wasn't present. [Greg Ames]
7548 *) Provide apr_socklen_t as a portability aid.
7549 [Victor J. Orlikowski]
7551 *) Overhaul of dbmmanage to allow a groups arg (as in Apache 1.2)
7552 as well as a comment arg to the add, adduser and update cmds.
7553 update allows the user to clear or preserve pw/groups/comment.
7554 Fixed a bug in dbmmanage that prevented the check option from
7555 parsing a password followed by :group... text. Corrected the
7556 seed calcualation for Win32 systems, and added -lsdbm support.
7559 *) Configured mod_auth_dbm to compile with sdbmlib under Win32.
7562 *) Avoid a segfault when parsing .htaccess files. An
7563 uninitialized tree pointer was passed to ap_build_config().
7566 *) Change the way that inet_addr & inet_network are checked for
7567 in APR's configure process to allow BeOS BONE to correctly
7568 find them. With this change BeOS BONE now builds from source
7569 with no problems. [David Reid]
7571 *) Fix a bug in apr_create_process() for Unix. The NULL signifying
7572 the end of the parameters to execve() was stored in the wrong
7573 location, overlaying the storage beyond the newargs[] array and
7574 also passing uninitialized storage to execve(), which would
7575 sometimes fail with EFAULT. [Jeff Trawick]
7577 *) Fix a bug parsing configuration file containers. With a sequence
7578 like this in the config file
7580 <IfModule mod_kilroy.c>
7583 <IfModule mod_lovejoy.c>
7588 the second container would be terminated at the blank line due to
7589 sediment in the buffer from reading the prior </IfModule> and an
7590 error message would be generated for the real </IfModule> for the
7591 second container. Also due to this problem, any two characters
7592 could be used for "</" in the close of a container.
7595 *) ap_add_filter prototype changed to remove the ctx pointer. The
7596 pointer still remains in the filter structure, but it can not be
7597 a part of the ap_add_filter prototype. The reason is that when
7598 the core uses AddFilter to add a filter to the stack it doesn't
7599 know how to allocate the ctx pointer, or even how much memory should
7600 be allocated. The filters will have to be responsible for allocating
7601 the ctx memory when they need it.
7604 *) Add an AddFilter directive. This directive takes a list of filters
7605 that should be activated for the requested resource.
7608 *) apr_snprintf(): Get quad format strings working on OS/390 (and perhaps
7609 some other platforms). [Jeff Trawick]
7611 *) Modify mod_include to be a filter. Currently, it has only been tested
7612 on actual files, but it should work for CGI scripts too.
7615 *) apr_putc(), apr_puts() for Unix: handle buffered files and interrupted
7616 writes. apr_flush() for Unix: handle interrupted writes.
7619 *) NameVirtualHost can now take "*" as an argument instead of
7620 an IP address. This allows you to create a purely name-based
7621 virtual hosting server that does not have any IP addresses in
7622 the configuration file and which ignores the local address
7623 of any connections. PR #5595, PR #4455 [Tony Finch]
7625 *) Fix some compile warnings in mod_mmap_static.c
7626 [Mike Abbott <mja sgi.com>]
7628 *) Fix chunking problem with CGI scripts. The general problem was that
7629 the CGI modules were adding an EOS bucket and then the core added an
7630 EOS bucket. The chunking filter finalizes the chunked response when it
7631 encounters an EOS bucket. Because two EOS buckets were sent, we
7632 finalized the response twice. The fix is to make sure we only send one
7633 EOS, by utilizing a flag in the request_rec.
7636 *) apr_put_os_file() now sets up the unget byte appropriately on Unix
7637 and Win32. Previously, the first read from an apr_file_t set up via
7638 apr_put_os_file() would return a '\0'. [Jeff Trawick]
7640 *) Mod_cgid now creates a single element bucket brigade, with a pipe
7641 bucket, instead of using BUFF's and ap_r*.
7644 *) APRVARS.in no longer overwrites the EXTRA_LIBS variable.
7645 [Mike Abbott <mja sgi.com>]
7647 *) Remove ap_bopenf from buff code. This required modifying the file_cache
7648 code to use APR file's directly instead of going through BUFFs.
7651 *) Fix compile break on some platforms for mod_mime_magic.c
7652 [John K. Sterling <sterling covalent.net>]
7654 *) Fix merging of AddDefaultCharset directive.
7655 PR #5872 (1.3) [Jun Kuriyama <kuriyama imgsrc.co.jp>]
7657 *) Minor revamp of the rlimit sections of code. We now test
7658 explicitly for setrlimit and getrlimit. Also, unixd_set_rlimit()
7659 is now "available" even if the platform doesn't support
7660 the rlimit family (it's just a noop though). [Jim Jagielski]
7662 *) Migrate the pre-selection of which MPM to use for specific
7663 platforms to hints.m4, which contains (or should contain)
7664 all platform specific "hints". [Jim Jagielski]
7666 *) Remove IOLs from Apache. With filtering, IOLs are no longer necessary
7669 *) Add tables with non-string/binary values to APR.
7672 *) Fix some bad calls to ap_log_rerror() in mod_rewrite.
7675 *) Update PCRE to version 3.2. [Ryan Bloom]
7677 *) Change the way buckets' destroy functions are called so that
7678 they can be more directly used when changing the type of a
7679 bucket in place. [Tony Finch]
7681 *) Add generic support for reference-counting the resources used by
7682 buckets, and alter the HEAP and MMAP buckets to use it. Change
7683 the way buckets are initialised to support changing the type of
7684 buckets in place, and use it when setting aside TRANSIENT buckets.
7685 Change the implementation of TRANSIENT buckets so that it can be
7686 mostly shared with IMMORTAL buckets, which are now implemented.
7689 Changes with Apache 2.0a6
7691 *) Add support to Apache and APR for dsos on OS/390. [Greg Ames]
7693 *) Add a chunking filter to Apache. This brings us one step closer
7694 to removing BUFF. [Ryan Bloom]
7696 *) ap_add_filter now adds filters in a LIFO fashion. The first filter
7697 added to the stack is the last filter to be called. [Ryan Bloom]
7699 *) Apache 2.0 has been completely documented using Scandoc. The
7700 docs can be generated by running 'make docs'. [Ryan Bloom]
7702 *) Add filtered I/O to Apache. This is based on bucket brigades,
7703 Currently the buckets still use BUFF under the covers, but that
7704 should change quickly. The only currently written filter is the
7705 core filter which just calls ap_bwrite. [The Apache Group]
7707 *) APR locks on Unix: Let APR_LOCKALL locks work when APR isn't
7708 built with thread support. [Jeff Trawick]
7710 *) Abort configuration if --with-layout was specified and there's
7711 no layout definition file. [Ken Coar]
7713 *) Add support for '--with-port=n' option to configure. [Ken Coar]
7715 *) Add support for extension methods for the Allow response header
7716 field, and an API routine for accessing r->allowed and the
7717 list of extension methods in a unified manner. [Ken Coar]
7719 *) mod_cern_meta: fix broken file reading loop in scan_meta_file().
7720 [Rob Simonson <simo us.ibm.com>]
7722 *) Get xlate builds working again. The apr renaming in 2.0a5 broke
7723 APACHE_XLATE builds. [Jeff Trawick]
7725 *) A configuration file parsing problem was fixed. When the
7726 configuration file started with an IfModule/IfDefine container,
7727 only the last statement in the container would be retained.
7730 Changes with Apache 2.0a5
7732 *) Perchild is serving pages after passing them to different child
7733 processes. There are still a lot of bugs, but this does work. I
7734 have made requests against the same installation of Apache, and had
7735 different servers use different user IDs to serve the responses.
7736 This change moves to using socketpair instead of an AF_UNIX socket.
7739 *) Perchild MPM still doesn't work perfectly, but it is serving pages.
7740 It can't seem to pass between child processes yet, but I think we
7741 are closer now than before. This moves us back to using Unix
7742 Domain Sockets. [Ryan Bloom]
7744 *) libapr functions and types renamed with apr_ prefix.
7745 #include "apr_compat.h" for 1.3.x backwards compat
7748 *) Fix problems with APR sockaddr handling on Win32. It didn't always
7749 return the right information on the local socket address.
7750 [Gregory Nicholls <gnicholls level8.com>]
7752 *) ap_recv() on Win32: Set bytes-read to 0 on error.
7753 [Gregory Nicholls <gnicholls level8.com>]
7755 *) Add an option to not detach from the controlling terminal without
7756 going into single process mode. This allows for much easier
7757 debugging of the process startup code. [Ryan Bloom]
7759 *) ab: don't use perror() to report the failure of an APR function.
7762 *) Make dexter, mpmt_pthread, and perchild MPMs not destroy the
7763 scoreboard on graceful restarts.
7766 *) Fix segfault/SIGSEGV when running gzip from mod_mime_magic.c.
7767 An invalid ap_proc_t was passed to ap_create_process().
7770 *) Allow modules to register filters. Those filters are still
7771 never called, but this is a step in the right direction.
7772 [Ryan Bloom and Greg Stein]
7774 *) Register the mod_cgid daemon process for cleanup so that it is
7775 killed at termination if it does not die when the parent gets
7776 SIGTERM. This change is to fix occasional problems where the
7777 process stays around. Bugs in similar logic in mod_rewrite and
7778 mod_include were also fixed. [Jeff Trawick]
7780 *) Fix a bug in the time handling. Basically, we were imploding a time
7781 in ap_parseHTTPdate, but it had bogus data in the exploded time format.
7782 Namely, tm_usec and tm_gmtoff were not filled out. ap_implode_time
7783 uses those two fields to adjust the time value. Because of the HTTP
7784 spec, both of those values can be zero'ed out safely. This fixes
7785 the bug correctly. [Ryan Bloom]
7787 *) Fix a couple of place in the Windows code where the wrong error
7788 code was being returned. [Gregory Nicholls <gnicholls level8.com>]
7790 *) Fix POOL_DEBUG (at least for prefork mpm). [Dean Gaudet]
7792 *) Added the APR_EOL_STR macro for platform dependent differences in
7793 logfiles and other raw text (such as all APR files). Fixes logfiles
7794 not terminated with cr/lf sequences in Win32. [William Rowe]
7796 *) Move all strings functions in APR to src/lib/apr/strings and create
7797 apr_strings.h for the prototypes. [Ryan Bloom]
7799 *) APR lock fixes: when using SysV sems, flock(), or fcntl(), be sure
7800 to repeat the syscall until we stop getting EINTR. I noticed a
7801 related problem at termination (SIGTERM) on FreeBSD when using
7802 fcntl(). Apache 1.3 had these new loops too. Also, make the flock()
7803 implementation work properly with child init. Previously, ap_lock()
7804 was essentially a no-op because all children were using different
7805 locks and thus nobody ever blocked. [Jeff Trawick]
7807 *) The htdocs/ tree has been moved out of the CVS source tree into
7808 a separate area for easier development. This has NO EFFECT on
7809 end-users or Apache installations. [Ken Coar]
7811 *) Integrate the mod_dav module for WebDAV protocol handling. This
7812 adds the dav and dav_fs modules, the SDBM library, and additional
7813 XML handling utilities. [Greg Stein]
7815 *) Clean out obsolete names (from httpd.h) for the HTTP Status Codes
7818 *) Update the lib/expat-lite/ library (bring forward changes from
7819 the Apache 1.3 repository). [Greg Stein]
7821 *) If sizeof(long long) == sizeof(long), then prefer long in APR
7822 configure.in. [Dave Hill <ddhill zk3.dec.com>]
7824 *) Add ap_sendfile for Tru64 Unix. Also, add an error message for
7825 machines where sendfile is detected, but nobody has written ap_sendfile.
7826 [Dave Hill <ddhill zk3.dec.com>]
7828 *) Compile fixes in mod_mmap_static. [Victor J. Orlikowski]
7830 *) ab would start up more connections than needed, then quit when the
7831 desired number were finished. Also fixed a logic error involving
7832 ab keepalives. [Victor J. Orlikowski]
7834 *) WinNT: Implement non-blocking pipes with timeouts to communicate
7835 with CGIs. Apache 2.0a4 had non-blocking pipes but without
7836 timeouts (i.e, if a timeout was specified, the pipe reverted to
7837 a full blocking pipe). Now the behaviour is more in line with
7838 Unix non-blocking pipes.
7841 *) WinNT: Implement accept socket reuse. Using mod_file_cache to
7842 cache open file handles along with accept socket reuse enables
7843 Apache 2.0 to serve non-keepalive requests for static files at
7844 3x the rate of Apache 1.3.(e.g, Apache 1.3 will serve 400 rps
7845 and Apache 2.0 will serve almost 1200 rps on my system).
7848 *) Merge mod_mmap_static function into mod_file_cache. mod_file_cache
7849 supports two config directives, mmapfile (same behavious as
7850 mod_mmap_static) and cachefile. Use the cachefile directive
7851 to cache open file handles. This directive only works on systems
7852 that have implemented the ap_sendfile API. cachefile works today
7853 on Windows NT, but has not been tested on any flavors of Unix.
7856 *) Cleanup the configuration. With the last few changes the
7857 configuration process automatically:
7858 inherits information about how to build from APR. Allowing
7859 APR to inform Apache that it should or should not use -ldl
7861 Detects which mod_cgi should be used mod_cgi or mod_cgid,
7862 based on the threading model
7864 Apache calls APR's configure process before finishing it's
7865 configuration processing, allowing for more information flow
7870 *) Change Unix and Win32 ap_setsockopt() so that APR_SO_NONBLOCK
7871 with non-zero argument makes the socket non-blocking. BeOS and
7872 OS/2 already worked this way. [Jeff Trawick]
7874 *) ap_close() now calls ap_flush() for buffered files, so write
7875 operations work a whole lot better on buffered files.
7878 *) Fix error messages issued from MPMs which explain where to change
7879 compiled-in limits (e.g., ThreadsPerChild, MaxClients, StartTreads).
7882 *) ap_create_pipe() now leaves pipes in blocking state. (This helps
7883 reduce the number of syscalls on Unix.) ap_set_pipe_timeout() is
7884 now the way that the blocking state of a pipe is manipulated.
7885 ap_block_pipe() is gone. [Jeff Trawick]
7887 *) Correct the problem where the only local host name that the IP stack
7888 can discover are 'undotted' private names. If no fully qualified
7889 domain name can be identified, the default ServerName will be set to
7890 the machine's IP address string. A warning is always provided if the
7891 ServerName not specified, but assumed. Solves PR6215 [William Rowe]
7893 *) Repair problems with config file processing which caused segfault
7894 at init when virtual hosts were defined and which caused ServerName to
7895 be ignored when there was no valid DNS setup. [Jeff Trawick]
7897 *) Removed pointless ap_is_aborted macro function. [Roy Fielding]
7899 *) Add ap_sendfile implementation for AIX
7900 [Victor J. Orlikowski]
7902 *) Repair C++ compatibility in ap_config.h, apr_file_io.h,
7903 apr_network_io.h, and apr_thread_proc.h.
7904 [Tyler J. Brooks <tylerjbrooks home.com>, Jeff Trawick]
7906 *) Bring the allocation and pool debugging code back into a working
7907 state. This will need to be tested as so far it's only been used on
7910 *) Change configuration command setup to be properly typesafe when in
7911 maintainer mode. Note that this requires a compiler that can initialise
7912 unions. [Ben Laurie]
7914 *) Turn on buffering for config file reads. Part of this was to
7915 repair buffered I/O support in Unix and implement buffered
7916 ap_fgets() for all platforms. [Brian Havard, Jeff Trawick]
7918 *) Win32: Fix problem where UTC offset was not being set correctly
7919 in the access log. Problem reported on news group by Jerry Baker.
7922 *) Fix segfault when reporting this type of syntax error:
7923 "</container> without matching <container> section", where
7924 container is VirtualHost or Directory or whatever.
7927 *) SECURITY: CVE-2000-1204 (cve.mitre.org)
7928 Prevent the source code for CGIs from being revealed when
7929 using mod_vhost_alias and the CGI directory is under the document root
7930 and a user makes a request like http://www.example.com//cgi-bin/cgi
7931 as reported in <news:960999105.344321 ernani.logica.co.uk>
7934 *) Add support for the new Beos NetwOrking Environment (BONE)
7937 *) xlate: ap_xlate_conv_buffer() now tells the caller when the
7938 final input char is incomplete; ap_bwrite_xlate() now handles
7939 incomplete final input chars. [Jeff Trawick]
7941 *) Yet another update to saferead/halfduplex stuff -- need to ensure
7942 that a bhalfduplex call occurs before logging or else DNS and
7943 such can delay the last packet of the response. [Dean Gaudet]
7945 *) Some syscall reduction in APR on unix -- don't seek when setting
7946 up an mmap; and don't fcntl() more than once per socket.
7949 *) When mod_cgid is started as root, the cgi daemon now switches
7950 to the configured User/Group (like other httpd processes)
7951 instead of continuing as root. [Jeff Trawick]
7953 *) The prefork MPM now uses an APR lock for the accept() mutex.
7954 It has not been getting a lock at all recently. httpd -V now
7955 displays APR's selection of the lock mechanism instead of the
7956 symbols previously respected by prefork. [Jeff Trawick]
7958 *) Change the mmap() feature test to check only for existence.
7959 The previous check required features not used by Apache.
7962 *) Fix a couple of bugs in mod_cgid: The cgi arguments were
7963 sometimes mangled. The len parm to accept() was not
7964 initialized, leading sometimes to an endless loop of failed
7965 accept() calls on OS/390 and anywhere else that failed the call
7966 if the len was negative. Use <sys/un.h> for struct sockaddr_un
7967 instead of declaring it ourselves to fix a compilation problem
7968 on Solaris. [Jeff Trawick]
7970 *) Add Resource limiting code back into Apache 2.0. [Ryan Bloom]
7972 *) Fix zombie process problem with mod_cgi. [Jeff Trawick]
7974 *) Port mod_mmap_static to 2.0. Make it go faster. [Greg Ames]
7976 *) Fix storage overlay when loading dsos. Symptom: Apache dies at
7977 initialization if ALLOC_DEBUG is defined; no known symptom
7978 otherwise. [Jeff Trawick]
7980 *) Fix typo in configure script when checking for mod_so. bash
7981 doesn't seem to have a problem but /bin/sh on Solaris does.
7982 Symptom: "./configure: test: unknown operator =="
7985 *) Rebind the Win32 NT and 9x services control into the MPM.
7986 All console, WinNT SCM and Win9x pseudo-service control code is
7987 now wrapped within the WinNT MPM.
7990 *) Make a copy of getenv("PATH") before storing for later use. Some
7991 getenv() implementations use the same storage for successive calls.
7992 CGIs on OS/390 had a bad PATH due to this. [Jeff Trawick]
7994 *) Server Tokens work in 2.0 again. This also propogates the change
7995 to allow just the product name in the server string using
7999 Changes with Apache 2.0a4
8001 *) EBCDIC: Rearrange calls to ap_checkconv() so that most handlers
8002 won't need to call it. [Greg Ames, Jeff Trawick]
8004 *) Move pre_config hook call to between configuration read and config
8005 tree walk. This allows all modules to implement pre_config hooks
8006 and know that they will be called at an appropriate time.
8009 *) mod_cgi, mod_cgid: Make ScriptLog directive work again.
8012 *) Add pre-config hooks back to all modules.
8015 *) Fix a SIGSEGV in ap_md5digest(), which is used when you have
8016 ContentDigest enabled and we can't/don't mmap the file.
8019 *) We now report the correct line number for syntax errors in config
8020 files. [Ryan Bloom, Greg Stein, Jeff Trawick]
8022 *) Brought mod_auth_digest up to synch with 1.3, fixed ap_time_t-
8023 related bugs, and changed shmem/locking to use apr API. Shared-mem
8024 is currently disabled, however, because of problems with graceful
8025 restarts. [Ronald Tschalär]
8027 *) Fix corruption of IFS variable in --with-module= handling.
8028 Depending on the user's shell or customization thereof, there
8029 would be errors generating ap_config_auto.h later in the configure
8030 procedure. [Jeff Trawick]
8032 *) mod_cgi: Restore logging of stderr from child process when ScriptLog
8033 isn't used (as in 1.3), except that on Unix it is now logged via
8034 ap_log_rerror() instead of by the child having STDERR_FILENO refer
8035 to the error log. [Greg Ames, Jeff Trawick]
8037 *) Add '-D' argument processing for run time configuration defines.
8040 *) Organize http_main.c as independent code, such that no code or
8041 global data is exported from it. WIN32 will dynamically link it
8042 to the server core, so this will prevent mutual dependency.
8045 *) Add separate dynamic linkage tags APR_EXPORT(), APR_EXPORT_NONSTD()
8046 and APR_VAR_EXPORT to correctly resolve apr functions and globals.
8049 *) Add Win9x service execution and Ctrl+C/Ctrl+Break/Shutdown handlers.
8050 [William Rowe, Jan Just Keijser <KEIJSERJJ logica.com>]
8052 *) Add mod_charset_lite for configuring character set translation.
8055 *) Add '-n' option to htpasswd to make it print its user:pw record
8056 on stdout rather than having to frob a text file. [Ken Coar]
8058 *) Fix saferead. Basically, we flush the output buffer if a read on the
8062 *) APR: Add ap_xlate_get_sb() so that an app can find out whether or not
8063 a conversion is single-byte only. [Jeff Trawick]
8065 *) BEOS: ap_shutdown should return APR_SUCCESS or errno. Note that
8066 the BeOS 5.0 documentation says that shutdown doesn't work yet.
8069 *) Fix some minor errors where pid was being manipulated as an int
8070 instead of the portable pid_t. [Roy Fielding]
8072 *) Fix some error log prints that were printing the pointer to a
8073 structure rather than the pid within the structure.
8074 [Jeff Trawick, Roy Fielding]
8076 *) ab: Fix a command-line processing bug; track bad headers in
8077 err_response; support reading headers up to 2K.
8078 [Ask Bjoern Hansen <ask valueclick.com>]
8080 *) Fix ap_resolve_env() so that it handles new function added in a prior
8081 alpha (see "Added the capability to do ${ENVVAR} constructs in the
8082 config file.") as well as the constructs used by mod_rewrite.
8083 [Paul Reder <rederpj raleigh.ibm.com>]
8085 *) Apache 2.0 builds and runs on OS/390. [Jeff Trawick, Greg Ames]
8087 *) Change the EBCDIC support in functions for MD5, SHA1, and base 64 to use
8088 APR to perform translation, instead of accessing the hard-coded tables
8089 in 1.3's ebcdic.c. [Jeff Trawick]
8091 *) Fix some bugs (mostly lost 1.3 code) in ab's command-line processing.
8094 *) Add the ability to hook into the config file reading phase. Basically
8095 if a directive is specified EXEC_ON_READ, then when that directive is
8096 read from the config file, the assocaited function is executed. This
8097 should only be used for those directives that must muck with HOW the
8098 server INTERPRETS the config. This should not be used for directives
8099 that re-order or replace items in the config tree. Those changes should
8100 be made in the pre-config step.
8103 *) Add mod_example to the build system.
8106 *) APR: Add ap_xlate_conv_byte() to convert one char between single-
8107 byte character sets. [Jeff Trawick]
8109 *) Pick up various EBCDIC fixes from 1.3 (from Martin
8110 Kraemer and Oliver Reh originally according to the change log).
8113 *) Fix a couple of problems in RFC1413 support (controlled by the
8114 IdentityCheck directive). Apache did not build the request string
8115 properly and more importantly Apache would loop forever if the
8116 would-be ident server dropped the connection before sending a
8117 properly terminated response. [Jeff Trawick]
8119 *) apxs works in 2.0.
8122 *) Reliable piped logs work in 2.0.
8125 *) Introduce a hash table implementation into APR to be used for
8126 replacing tables and other random data structures in Apache.
8129 *) Add some more error reporting to htpasswd in the case of problems
8130 generating or accessing the temporary file. Also, pass in a
8131 buffer if the implementation knows how to use it (i.e., if L_tmpnam
8132 is defined). [Ken Coar]
8134 *) Configure creates config.nice now containing your configure
8135 options. Syntax: ./config.nice [--more-options]
8138 *) Fix various return code problems in APR on Win32. For most of
8139 these, APR was returning APR_EEXIST instead of GetLastError()/
8140 WSAGetLastError(). [Jeff Trawick]
8142 *) Make piped logs work again in version 2.0
8145 *) Add VPATH support to UNIX build system of Apache and APR.
8148 *) Fix ap_tokenize_to_argv to respect the const arguments that are
8152 *) Fix mm's memcpy/memset macros, pointer arithmetic was broken.
8153 Patch submitted to author.
8156 *) Fix mm configuration on Solaris 8 x86 and OS/390. Don't require
8157 /sbin in PATH on FreeBSD (all submitted to rse previously)
8160 *) Fix building Pthread-based MPMs on OpenBSD
8161 [Sascha Schumann] PR#26
8163 *) Fix ap_readdir() problem on systems where d_name[] field in
8164 struct dirent is declared with only one byte. (This problem only
8165 affected multithreaded builds.) This caused a segfault during
8166 pool cleanup with mod_autoindex on Solaris (Solaris 8 x86, at
8167 least). [Jeff Trawick]
8169 *) Fix some make-portability problems on at least Tru64, Irix
8171 [Sascha Schumann] PR#18, PR#39
8173 *) Add ap_sigwait() to support old-style sigwait() on systems
8174 like OS/390 and UnixWare.
8177 *) Add POSIX-thread flags for more platforms.
8180 *) Fix some minor bugs in ap_strerror(). Teach ap_strerror()
8181 (on Unix, at least) to handle resolver errors. Fix a bug in
8182 the definition of APR_ENOMEM so that ap_strerror() can spit
8183 out the correct error message for it.
8186 Changes with Apache 2.0a3
8188 *) mod_so reports ap_os_dso_error() if ap_dso_load() fails
8191 *) API: *HOOK* macros now have an AP_ prefix
8194 *) Win32: Eliminate redundant calls to initialize winsock.
8195 [Tim Costello <timcostello ozemail.com.au>]
8197 *) Fix bugs initializing ungetchar for pipes.
8198 [Chia-liang Kao <clkao CirX.ORG>]
8200 *) The ab program in the src/support directory is now portable using
8204 *) Support directory is being compiled when the server is built
8207 *) The configure option --with-program-name has been added to allow
8208 developers to rename the executable at configure time. This also
8209 changes the name of the config files to match the executable's name.
8212 *) mod_autoindex: Add `IndexOptions +VersionSort', to nicely sort filenames
8213 containing version numbers. [Martin Pool]
8215 *) ap_open(..,APR_OS_DEFAULT,..) uses perms 0666 instead of 0777 on
8216 Unix; access_log and error_log now created with these perms; non-
8217 Unix is unaffected [Jeff Trawick]
8219 *) Finished move of ap_md5 routines to apr_md5. Removed ap_md5.h.
8220 Replaced more magic numbers with MD5_DIGESTSIZE.
8221 [William Rowe, Roy Fielding]
8223 *) Win32: Get mod_auth_digest compiling and added to the Windows
8224 build environment. Not tested and I'd be suprised if it
8225 actually works. [Bill Stoddard]
8227 *) Revamp the Win32 make environment. Makefiles have been removed and
8228 Apache.dsw created to bring together all the pieces. Create new file
8229 os/win32/BaseAddr.ref to define module base addresses (to prevent
8230 dll relocation at start-up).
8231 [William Rowe, Greg Marr, Tim Costello, Bill Stoddard]
8233 *) [EBCDIC] Port Paul Gilmartin's CRLF patch from 1.3. This replaces most
8234 of the \015, \012, and \015\012 constants with macros.
8237 *) Add ap_xlate_open() et al for translation of text between different
8238 character sets. The initial implementation requires iconv().
8241 *) More FAQs and answers from comp.infosystems.www.servers.unix.
8242 [Joshua Slive <slive finance.commerce.ubc.ca>]
8244 *) CGI output is being timed out now.
8247 *) Fix the problem with dieing quietly. dupfile now takes a pool which
8248 is used by the new apr file. There is no reason to create a new file
8249 with the same lifetime as the original file.
8252 *) Win32: Attempt to eliminate dll relocation at start-up by specifying
8253 module base addresses. This will help shooting seg faults
8254 in the field. [William Rowe <wrowe lnd.com>]
8256 *) Update Apache on Windows documentation. Add new document
8257 describing how to compile Apache on Windows.
8258 [William Rowe <wrowe lnd.com>]
8260 *) ap_set_pipe_timeout(), ap_poll(), and APR_SO_TIMEOUT now take
8261 microseconds instead of seconds. Some storage leaks and other
8262 minor bugs in related code were fixed. [Jeff Trawick]
8264 *) Win32: First cut at getting mod_isapi working under 2.0
8265 [William Rowe <wrowe lnd.com>]
8267 *) First stab at getting mod_auth_digest working under 2.0
8268 quick change summary:
8269 - moved the random byte generation (ap_generate_random_bytes) into APR
8270 - now uses ap_time_t
8271 - compiles and runs on linux
8273 [Brian Martin <bmartin penguincomputing.com>]
8275 *) Win32: Move the space stripping of physical service names
8276 fix up from Apache 1.3. #include'ing "ap_mpm.h" fixes up an
8277 unresolved symbol. Add dependency checking to the
8278 CreateService call to ensure TCPIP and AFP (winsock) is started
8280 [William Rowe <wrowe lnd.com>]
8282 *) Win32: Add code to perform latebinding on functions that may
8283 not exist on all levels of Windows where Apache runs. This
8284 is needed to allow Apache to start-up on Win95/98. All calls
8285 to non portable functions should be protected with
8286 ap_oslevel checks to prevent runtime segfaults.
8287 [William Rowe <wrowe lnd.com>]
8289 *) Fix fallback default values for SHM_R and SHM_W [Martin Kraemer]
8291 *) Get lingering_close() working again. [Dean Gaudet, Jeff Trawick]
8293 *) Win32: Get non-blocking CGI pipe reads working under Windows NT.
8294 This addresses PR 1623. Still need to address timing out runaway
8295 CGI scripts. [Bill Stoddard]
8297 *) Win32: Make ap_stat Windows 95/98 friendly
8298 [William Rowe <wrowe lnd.com>]
8300 *) Win32: Fix a bug in ap_get_oslevel which causes GetVersionEx() to
8301 always fail. Need to initialise the dwOSVersionInfoSize member of the
8302 OSVERSIONINFO struct before calling GetVersionEx, so GetVersionEx
8305 The patch also enhances ap_get_oslevel (and the associated enum) to
8306 handle selected service packs for NT4, and adds recognition for
8307 Windows 2000. This is useful, eg. if we can recognise NT4 SP2 then
8308 we can use ReadFileScatter and WriteFileGather in readwrite.c.
8309 [Tim Costello <Tim.Costello BTFinancialgroup.com>]
8311 *) Get mod_rewrite building and running, and mod_status building for Win NT
8312 [Allan Edwards <ake raleigh.ibm.com>]
8314 *) Patch to port mod_auth_db to the 2.0 api and also to support
8315 Berlekey DB 3.0. It works for me with both Berkeley DB 3.0.55 and
8316 2.7.7. It should work with version 1 as well but I haven't tested it.
8317 [Brian Martin <bmartin penguincomputing.com>]
8319 *) Get APR DSO code working under Windows. Includes cross platform
8321 [<Tim.Costello BTFinancialgroup.com>]
8323 *) Fix some of the Windows APR time functions.
8326 *) FAQ changes related to tidying up historical documents on the web site.
8327 [Joshua Slive <slive finance.commerce.ubc.ca>]
8329 *) Move Windows DSO code into APR.
8332 *) Eliminate apr_win.h and apr_winconfig.h (and the ugly #ifdefs they cause).
8333 Now, apr.h and apr_config.h are generated from apr.hw and apr_config.hw
8334 at build time. At this point, the server will not compile on Windows because
8335 of the recent DSO commits. Fixing those next.
8336 [Bill Rowe & Bill Stoddard]
8338 *) Added error checking for file I/O APR routines.
8339 [Jon Travis <jtravis covalent.net>]
8341 *) APR: Don't use the values of resolver error codes for the
8342 corresponding APR error codes. On Unix and Win32, return the
8343 proper APR error code after a resolver error. [Jeff Trawick]
8345 Changes with Apache 2.0a2
8347 *) Renamed the executable back to httpd on all platforms other
8351 *) Allow BeOS to survive restarts, log properly and a few
8352 small things it had problems with due to the way it setup
8353 users and groups. [David Reid]
8355 *) Get mod_rewrite working with APR locks
8356 [Paul Reder <rederpj raleigh.ibm.com>]
8358 *) Actually remove the sempahore when the lock cleanup routine
8359 is called on BeOS. [David Reid]
8361 *) Clear hook registrations between reads of the config file.
8362 When DSOs are unloaded and re-loaded the old hook pointers may
8363 no longer be valid. This fix eliminates potential segfaults.
8364 [Allan Edwards <ake raleigh.ibm.com>]
8366 *) Fix a problem with Sigfunc not being defined or bypassed
8367 if sigaction() wasn't found. [Jim Jagielski]
8369 *) Fix the locking mechanism on BSD variants. They now use fcntl
8370 locks. This allows the server to start and serve pages.
8373 *) First cut at getting the Win32 installer to work
8374 [William Rowe <wrowe lnd.com>]
8376 *) Get htpasswd compiling under Windows
8377 [William Rowe <wrowe lnd.com>]
8379 *) Change the log message for a bind() failure to show the
8380 interface and port number. [Jeff Trawick]
8382 *) Import the documentation from 1.3.12 and bring parts of it
8383 up-to-date with respect to the changes that have occurred
8387 *) BeOS MPM updated. CGI bug on BeOS fixed. IP addresses
8388 now logged correctly on BeOS.
8391 *) Create one makefile for all Win32 distributions (NT/2000/95/98).
8392 Makefile.win includes the same user interface as the old
8394 [William Rowe <wrowe lnd.com>, Jeff Trawick <trawick us.ibm.com>]
8396 *) Win32 exec now uses COMSPEC environment string for command
8397 shell path resolution.
8398 [William Rowe <wrowe lnd.com>] PR#3715
8400 *) Win32: ap_connect() was not returning correct error condition
8402 [Allen Prescott <allen clanprescott.com>]
8404 *) Win32: ap_open() was broken on Win9x because an NT-specific
8405 flag was passed to CreateFile. ap_puts() added an unnecessary
8407 [Jeff Trawick <trawick us.ibm.com>]
8409 *) Put in Korean and Norwegian index.html pages (2.0 and 1.3)
8410 which where donated by Lee Kuk Hyun and Lorant Czaran. 'Fixed'
8411 confusing ee/et name and made all extensions language/dialect
8412 rather than country reflecting. Changed example files to
8413 explicit reflect the ISO charset and added a few common
8414 ones to the example config [dirkx]
8416 *) Extend external module capability. To use this, you call
8417 configure with --with-module=path/to/mod1,path/to/mod2,etc.
8420 *) Backported the various "default charset" fixes from 1.3.12,
8421 including the AddDefaultCharset directive. [Jim Jagielski]
8423 *) Added the capability to do ${ENVVAR} constructs in the
8424 config file. E.g. 'ServerAdmin ${POSTMASTER}'. As commited
8425 it does this on a line by line basis; i.e. if the envvar
8426 expands to something with spaces you have to protect it
8427 by adding quotes around it (Unless of course you expect it
8428 to contains more than one argument. Alternatively you
8429 can compile it on a per token basis; which is what people
8430 usually expect by setting RESOLVE_ENV_PER_TOKEN. But this
8431 hampers fancier hacks.
8432 [Dirk-Willem van Gulik]
8434 *) Changed the 'ErrorDocument' syntax in that it NO longer
8435 supports the asymetric
8437 ErrorDocument 301 "Some message
8439 Note the opening " quote, without a closing quote. It now
8440 has either the following syntaxes
8442 ErrorDocument XXX /local/uri
8443 ErrorDocument XXX http://valid/url
8444 ErrorDocument XXX "Some Message"
8446 The recognition heuristic is: if it has a space it
8447 is a message. If it has no spaces and starts with a /
8448 or is a valid URL then treat it that way. Otherwise it
8449 is assumed to be a message.
8451 This breaks backward compatibility but makes live a hell
8452 of a lot easier for GUI's and config file parsers.
8453 [Dirk-Willem van Gulik]
8455 *) Changed 'CacheNegotiatedDocs' from its present/not-present
8456 syntax into a 'on' or 'off' syntax. As it currently is the
8457 only non nesting token which uses NO_ARGS and thus is an
8458 absolute pain for any config interface automation. This
8459 breaks backward compatibility. [Dirk-Willem van Gulik]
8461 *) Add ability to add external modules to the build process. This is
8462 done with --with-module=/path/to/module. Modules can only be added
8463 as static modules at this point.
8466 Changes with Apache 2.0a1
8468 *) Fix FreeBSD 3.3 core dump.
8469 Basically, ap_initialize() needs to get called before
8470 create_process(), since create_process() passes op_on structure
8471 to semop() to get a lock, but op_on isn't initialized until
8472 ap_initialize() calls setup_lock(). Here is a slight
8473 rearrangement to main() which calls ap_initialize() earlier...
8474 [Jeff Trawick <trawick us.ibm.com>]
8476 *) Enable Apache to use sendfile/TransmitFile API
8477 [Bill Stoddard, David Reid, Paul Reder]
8479 *) Re-Implement Win32 APR network I/O APIs and most of the file I/O
8483 *) Make file I/O and network I/O writev/sendv APIs consistent.
8484 Eliminate use of ap_iovec_t and use Posix struct iovec.
8485 Use seperate variable on ap_writev to set the number of iovecs
8486 passed in and number of bytes written.
8489 *) Adapt file iol to use APR functions. Replaced ap_open_file()
8490 with ap_create_file_iol(). ap_create_file_iol() requires that
8491 the file be opened prior to the call using ap_open().
8494 *) Port mod_include and mod_cgi to 2.0
8495 [Paul Reder, Bill Stoddard]
8497 *) ap_send{,v}, ap_recv, ap_sendfile API clarification --
8498 bytes_read/bytes_written is always valid (never -1). Plus
8499 some fixes to buff.c to correct problems introduced by the
8500 errno => ap_status_t changes a while back. Plus a fix to
8501 chunked encoding introduced right at the beginning of 2.0.
8504 *) Revamped UNIX build system to use autoconf and libtool.
8505 [Manoj Kasichainula, Sascha Schumann]
8507 *) port mod_rewrite to 2.0. [Paul J. Reder <rederpj raleigh.ibm.com>]
8509 *) SECURITY: More rigorous checking of Host: headers to fix security
8510 problems with mass name-based virtual hosting (whether using mod_rewrite
8511 or mod_vhost_alias).
8512 [Ben Hyde, Tony Finch]
8514 *) Add back support for UseCanonicalName in <Directory> containers.
8515 [Manoj Kasichainula]
8517 *) Added APLOG_STARTUP log type. This allows us to write an error
8518 message without any of the date and time information. As a part
8519 of this change, I also removed all of the calls to fprintf(stderr
8520 and replaced them with calls to ap_log_error using APLOG_STARTUP
8521 writing to stderr is no longer portable, because we don't direct
8522 stderr to the error log on all platforms.
8525 *) Convert error logging functions to take errno as an argument.
8526 This makes our error logs more portable, because some Windows API's
8527 don't set errno. This change allows us to still output a valid
8528 message on all of our platforms.
8531 *) mod_mime_magic runs in 2.0-dev now.
8532 [Paul Reder <rederpj raleigh.ibm.com>]
8534 *) sendfile has been added to APR.
8535 [John Zedlewski <zedlwski Princeton.EDU>]
8537 *) buff.c has been converted to no longer use errno.
8538 [Manoj Kasichainula]
8540 *) mod_speling runs in 2.0-dev now: a bug in readdir_r handling and
8541 interface adaption to APR functions did it. [Martin Kraemer]
8543 *) Support DSOs properly on 32-bit HP-UX 11.0
8544 [Dilip Khandekar <dilip cup.hp.com>]
8546 *) Updated MM in APR source tree from version 1.0.8 to 1.0.11
8547 [Ralf S. Engelschall]
8549 *) Cleaned APR build environment integration and bootstrap APR
8550 automatically for developers from src/Configure.
8551 [Ralf S. Engelschall]
8553 *) Fixed building of src/support/htpasswd.c
8554 [Ralf S. Engelschall]
8556 *) When generating the Location: header, mod_speling forgot
8557 to escape the spelling-fixed uri. (Forw-Port from 1.3)
8560 *) Moved mod_auth_digest.c from experimental to standard. [Roy Fielding]
8562 *) Change all pools to APR contexts. This is the first step to
8563 incorporating APR into Apache. [Ryan Bloom]
8565 *) Move "handler not found" warning message to below the check
8566 for a wildcard handler. [Dirk <dirkm teleport.com>, Roy Fielding]
8567 PR#2584, PR#2751, PR#3349, PR#3436, PR#3548, PR#4384, PR#4795, PR#4807
8569 *) Support line-continuation feature in config.option file and
8570 allow the loading of multiple option sections at once via
8571 ``--with-option=<section1>,<section2>,...''
8572 [Ralf S. Engelschall]
8574 *) Rebuilt CVS repository with Apache 1.3.9 as basis. [Roy Fielding]
8576 Changes with Apache MPM
8578 *) Use asynchronous AcceptEx() and a completion port to accept and
8579 dispatch connections to threads in Windows NT/2000.
8582 *) Implement WINNT Win32 MPM from original Win32 code in http_main.c
8585 *) Implement the APACI --with-option facility
8586 (per default used the config.option file).
8587 [Ralf S. Engelschall]
8589 *) MPM BEOS port. [David Reid <abb37 dial.pipex.com>]
8591 *) Start to implement module-defined hooks that are a) fast and b) typesafe.
8592 Replace pre_connection module call with a register_hook call and
8593 implement pre_connection as a hook. The intent is that these hooks will
8594 be extended to allow Apache to be multi-protocol, and also to allow the
8595 calling order to be specified on a per-hook/per-module basis.
8598 *) Implement mpm_* methods as "modules". Each method gets its own
8599 subdir in src/modules (eg: src/modules/prefork). Selection
8600 of method uses Rule MPM_METHOD. [Jim Jagielski]
8602 *) Port the hybrid server from the apache-apr repository as
8603 mpm_mpmt_pthread. [Manoj Kasichainula]
8605 *) os/unix/unixd.[ch]: detach, setuid, setgid, stuff which will be common
8606 amongst the unix MPMs.
8608 *) mpm_prefork: throw away all the alarm/timeout crud; and clean up the
8609 signal handling for the new world order. [Dean Gaudet]
8611 *) Crude ap_thread_mutex abstraction so that we get the pthread stuff out
8612 of alloc.c for now. [Dean Gaudet]
8614 *) Handle partial large writes correctly. [Ben Laurie]
8616 *) Eliminate conn_rec's pointer to server. All it knows is the base server
8617 based on IP/port. [Ben Laurie]
8619 *) Port a bunch of modules to the new module structure.
8620 ["Michael H. Voase" <mvoase midcoast.com.au>]
8622 *) I/O layering and BUFF revamp. See docs/buff.txt. [Dean Gaudet]
8624 *) Basic restructuring to introduce the MPM concept; includes various
8625 changes to the module API... better described by
8626 docs/initial_blurb.txt. [Dean Gaudet]
8628 Changes with Apache pthreads
8630 *) New buff option added: BO_TIMEOUT. It describes the timeout for
8631 buff operations (generally over a network).
8632 [Dean Gaudet, Ryan Bloom, Manoj Kasichainula]
8634 *) Created http_accept abstraction. Added 4 new functions (not exported):
8635 init_accept(), begin_accepting_requests(), get_request(),
8636 stop_accepting_requests() [Bill Stoddard]
8638 *) Fix to ap_rprintf call that allows mod_info to work properly.
8639 [James Morris <jmorris intercode.com.au>]
8641 *) user and ap_auth_type fields were moved from connection_rec to
8642 request_rec. [Ryan Bloom]
8644 *) Removed the ap_block_alarms and ap_unblock_alarm calls. These aren't
8645 needed in a threaded server.
8647 *) Initial pthread implementation from from Dean's apache-nspr code.
8648 [Bill Stoddard, Ryan Bloom]
8651 Changes with Apache 1.3.9
8653 *) Remove bogus error message when a redirect doesn't set Location.
8654 Instead, use an empty string to avoid coredump if the error message
8655 was supposed to include a location. [Roy Fielding]
8657 *) Don't allow configure to include mod_auth_digest unless it is
8658 explicitly requested, even if the user asked for all modules.
8661 *) Translate module names to dll names for OS/2 so that they are no more
8662 than 8 characters long and have an extension of "dll" instead of "so".
8665 *) Print out pointer to Rule DEV_RANDOM when truerand lib not found.
8666 Fix test-compile check to check for randbyte instead of trand32.
8667 Use ap_base64encode_binary/decode instead of copy in mod_auth_digest.c
8668 and tweak to make Amaya happier. [Ronald Tschalär]
8670 *) Ensure that the installed expat include files are world readable,
8671 just like the other header files. [Martin Kraemer]
8673 *) Fixed generated AddModule adjustments in APACI's `configure' script
8674 in order to allow (new) modules like mod_vhost_alias to be handled
8675 correctly (which was touched by the adjustments for mod_alias).
8676 [Ralf S. Engelschall]
8678 *) For binary builds, add -R flag to apachectl to work around the lack of
8679 an absolute path to the ./libexec directory where the libhttp.ep file
8680 is needed for SHARED_CORE architectures. [Randy Terbush]
8682 *) WIN32: Create the CGI script process as DETACHED. This may solve the
8683 problem observed by some Win95/98 users where they get CGI script
8684 output sent to the console. [Bill Stoddard]
8686 *) Fix (re)naming in the uuencode/decode section. The ap/ap_
8687 routines are now called ap_base64* and are 'plain' (i.e., no
8688 pool access or anything clever). Inside util.c the routines acting
8689 like pstrdup are called ap_pbase64encode() and ap_pbase64decode().
8690 The oddly named ap_uuencode(), ap_uudecode() are kept around for
8691 now but deprecated. [dirkx]
8693 *) Clean up the base64 and SHA1 additions and make sure they are
8694 represented in the ApacheCore.def, ApacheCoreOS2.def, and httpd.exp
8695 files. [Roy Fielding]
8697 *) WIN32: Migrate to InstallShield 5.5 and provide a bit more error
8698 checking. Allow compiling on VS 6.0. [Randy Terbush]
8700 *) Fixed assumption of absolute paths in binbuild.sh. [Tony Finch]
8702 *) Use TestCompile to search for the truerand library (rather than blindly
8703 assuming its existence). If it is not found, complain (but do not
8704 exit - yet). [Martin Kraemer]
8706 *) We forgot to add the new exported function names to
8707 src/support/httpd.exp. [Bill Stoddard, Randy Terbush]
8709 *) Add description of -T command-line option to usage().
8710 [Ralf S. Engelschall]
8712 *) For "some" platforms (notably, EBCDIC based ones), libos needs to be
8713 searched only AFTER libap has been searched, because libap needs
8714 some symbols from libos. [Martin Kraemer]
8716 *) Fix conflict with original mod_digest related to the symbol of the
8717 module dispatch list (which has to be unique for DSO and follow the
8718 usual conventions for the installation procedure).
8719 [Ralf S. Engelschall]
8721 *) Add a dbm-library check for the "usual places" (-ldbm, -lndbm, -ldb)
8722 for other platforms as well. [Martin Kraemer]
8724 *) Make ap_sha1.c compile for EBCDIC platforms: replace remaining LONG
8725 types by AP_LONG and replace reference to renamed variable 'ubuf'
8726 by 'buffer'. [Martin Kraemer]
8728 Changes with Apache 1.3.8 [not released]
8730 *) Flush the output buffer immediately after sending an error or redirect
8731 response, since the result may be needed by the client to abort a
8732 long data transfer or restart a series of pipelined requests.
8733 [Tom Vaughan <tvaughan aventail.com>, Roy Fielding]
8735 *) PORT: Improved compilation and DSO support on Sequent DYNIX/ptx.
8736 [Ian Turner <iant sequent.com>] PR#4735
8738 *) Local struct mmap in http_core.c conflicted with system structure
8739 name on DYNIX -- changed to mmap_rec. [Roy Fielding] PR#4735
8741 *) Added updated mod_digest as modules/experimental/mod_auth_digest.
8742 [Ronald Tschalär <ronald innovation.ch>]
8744 *) Fix a memory leak where the module counts were getting messed
8745 up across restarts. [David Harris <dharris drh.net>]
8747 *) CIDR addresses such as a.b.c.d/24 where d != 0 weren't handled
8748 properly in mod_access.
8749 ["Paul J. Reder" <rederpj raleigh.ibm.com>] PR#4770
8751 *) RewriteLock/RewriteMap didn't work properly with virtual hosts.
8752 [Dmitry Khrustalev <dima bog.msu.su>] PR#3874
8754 *) PORT: Support for compaq/tandem/com.
8755 [Michael Ottati <michael.ottati compaq.com>, dirkx]
8757 *) Added SHA1 password encryption support to easy migration from
8758 Netscape servers. See support/SHA1 for more information.
8759 Caused the separation of ap_md5.c into md5, sha1 and a general
8760 ap_checkpass.c with just a validate_passwd routine. Added a
8761 couple of flags to support/htpasswd. Some reuse of the to64()
8762 function; hence renamed to ap_to64().
8763 [Dirk-Willem van Gulik, Clinton Wong <clintdw netcom.com>]
8765 *) Change for EBCDIC platforms (TPF and BS2000) to correctly deal
8766 with ASCII/EBCDIC conversions in "ident" query.
8767 [David McCreedy <McCreedy us.ibm.com>]
8769 *) Get rid of redefinition warning on MAC_OS_X_SERVER platform.
8770 Change "Power Macintosh" to Power* so if uname prints "Power Book"
8771 we're still happy on Rhapsody platforms. [Wilfredo Sanchez]
8773 *) Fix SIGSEGV on some systems because the Vary fix below included
8774 a call to table_do with a variable argument list that was not
8775 NULL terminated. Replaced with better implementation. [Roy Fielding]
8777 Changes with Apache 1.3.7 [not released]
8779 *) The "Vary" response header field is now sanitised right before
8780 the header is sent back to the client. Multiple "Vary" fields
8781 are combined, and duplicate tokens (e.g., "Vary: host, host" or
8782 "Vary: host, negotiate, host, accept-language") are reduced to
8783 single instances. This is a better solution than the force-no-vary
8784 one (which is still valid for clients that can't cope with Vary
8785 at all). PR#3118 [Dean Gaudet, Roy Fielding, Ken Coar]
8787 *) Portability changes for BeOS. [David Reid <abb37 dial.pipex.com>]
8789 *) Link DSO's with "gcc -shared" instead of "ld -Bshareable" at
8790 least on Linux and FreeBSD for now.
8793 *) Win32: More apache -k restart work. Restarts are now honored
8794 immediately and connections in the listen queue are -not- lost.
8795 This is made possible by the use of the WSADuplicateSocket()
8796 call. The listeners are opened in the parent, duplicated, then
8797 the duplicates are passed to the child. The original listen sockets
8798 are not closed by the parent across a restart, thus the listen queue
8800 [Bill Stoddard <stoddard raleigh.ibm.com>]
8802 *) Fix handling of case when a client has sent "Expect: 100-continue"
8803 and we are going to respond with an error, but get stuck waiting to
8804 discard the body in the pointless hope of preserving the connection.
8805 [Roy Fielding, Joe Orton <jeo101 york.ac.uk>] PR#4499, PR#3806
8807 *) Fix 'configure' to work correctly with SysV-based versions of
8808 'tr' (consistent with Configure's use as well). [Jim Jagielski]
8810 *) apxs: Add "-S var=val" option which allows for override of CFG_*
8811 built-in values. Add "-e" option which works like -i but doesn't
8812 install the DSO; useful for editing httpd.conf with apxs. Fix
8813 editing code so that multiple invocations of apxs -a will not
8814 create duplicate LoadModule/AddModule entries; apxs can now be
8815 used to re- enable/disable a module. [Wilfredo Sanchez]
8817 *) Win32: Update the server to use Winsock 2. Specifically, link with
8818 ws2_32.lib rather than wsock32.lib. This gives us access to
8819 WSADuplcateSocket() in addition to some other enhanced comm APIs.
8820 Win 95 users may need to update their TCP/IP stack to pick up
8821 Winsock 2. (See http://www.microsoft.com/windows95/downloads/)
8822 [Bill Stoddard <stoddard raleigh.ibm.com>]
8824 *) Win32: Redirect CGI script stderr (script debug info) into the
8825 error.log when CGI scripts fail. This makes Apache on Win32
8826 behave more like Unix.
8827 [Bill Stoddard <stoddard raleigh.ibm.com>]
8829 *) Fixed `httpd' usage display: -D was missing.
8830 [Ralf S. Engelschall] PR#4614
8832 *) Fix `make r' test procedure in src/regex/: ap_isprint was not found.
8833 [Ralf S. Engelschall] PR#4561, PR#4562
8835 *) OS/2: Fix problem with accept lock semaphores where server would die with
8836 "OS2SEM: Error 105 getting accept lock. Exiting!"
8837 [Brian Havard] PR#4505
8839 *) Add DSO support for DGUX 4.x using gcc. Tested on x86 platforms.
8840 [Randy Terbush <randy covalent.net>]
8842 *) Add the new mass-vhost module (mod_vhost_alias.c) developed and
8843 used by Demon Internet, Ltd. [Tony Finch <fanf demon.net>]
8845 *) Better GCC detection for DSO flags under Solaris 2 where the `cc'
8846 command potentially _is_ GCC. [Ralf S. Engelschall]
8848 *) Fix apxs build issues on AIX
8849 [Rasmus Lerdorf <rasmus raleigh.ibm.com>]
8851 *) DocumentRoot Checking: Under previous versions, when Apache
8852 first started up, it used to do a stat of each DocumentRoot to
8853 see if it existed and was a directory. If not, then an error
8854 message was printed. THIS HAS BEEN DISABLED. If DocumentRoot
8855 does not exist, you will get error messages in error_log. If
8856 the '-t' command line option is used (to check the configuration)
8857 the check of DocumentRoot IS performed. An additional command
8858 line option, '-T', has been added if you want to avoid the
8859 DocumentRoot check even when checking the configuration.
8862 *) Win32: The query switch "apache -S" didn't exit after showing the
8863 vhost settings. That was inconsistent with the other query functions.
8864 [Bill Stoddard - Fixed by Martin on Unix in 1.3.4]
8866 *) Win32: Changed behaviour of apache -k restart.
8867 Previously, the server would drain all connections in the stack's
8868 listen queue before honoring the restart. On a busy server, this
8869 could take hours. Now, a restart is honored almost immediately.
8870 All connections in Apache's queues are handled but connections in
8871 the stack's listen queue are discarded. Restart triggered by
8872 MaxRequestPerChild is unchanged.
8873 [Bill Stoddard <stoddard raleigh.ibm.com>]
8875 *) Win32: Eliminated unnecessary call to wait_for_multiple_objects in
8876 the accept loop. Good for a 5% performance boost. Cleaned up
8877 parent/child process management code.
8878 [Bill Stoddard <stoddard raleigh.ibm.com>]
8880 *) Added ceiling on file size for memory mapped files.
8881 [John Giannandrea <jg meer.net>] PR#4122
8883 *) Fix ndbm.h include problems with brain-dead glibc >= 2.1 which
8884 has ndbm.h in a non-standard db1/ subdir. PR#4431, PR#4528
8885 [Henri Gomez <gomez slib.fr>, Ralf S. Engelschall]
8887 *) Determine AP_BYTE_ORDER for ap_config_auto.h and already
8888 use this at least for Expat. [Ralf S. Engelschall]
8890 *) Allow .module files to specify libraries with Lib:.
8893 *) Allow SetEnvIf[NoCase] to test environment variables as well
8894 as header fields and request attributes. [Ken Coar]
8896 *) Fix mod_autoindex's handling of ScanHTMLTitles when file
8897 content-types are "text/html;parameters". PR#4524 [Ken Coar]
8899 *) Remove "mxb" support from mod_negotiation -- it was a draft feature
8900 never accepted into any standard, and it opens up certain DoS
8901 attacks. [Koen Holtman <Koen.Holtman cern.ch>]
8903 *) TestCompile updated. We can now run programs and output the
8904 results during the Configure process. [ Jim Jagielski]
8906 *) The source is now quad (long long) aware as needed. Specifically,
8907 the Configure process determines the correct size of off_t and
8908 *void. When the OS/platform/compiler supports quads, ap_snprintf()
8909 provides for the 'q' format qualifier (if quads are not available,
8910 'q' is silently "demoted" to long). [Jim Jagielski]
8912 *) When the username or password fed to htpasswd is too long, include the
8913 size limit in the error message. Also report illegal characters
8914 (currently only ':') in the username. Add the size restrictions
8915 to the man page. [Ken Coar]
8917 *) Fixed the configure --without-support option so it doesn't result in
8918 an infinite loop. [Marc Slemko]
8920 *) Piped error logs could cause a segfault if an error occured
8921 during configuration after a restart.
8922 [Aidan Cully <aidan panix.com>] PR#4456
8924 *) If a "Location" field was stored in r->err_headers_out rather
8925 than r->headers_out, redirect processing wouldn't find it and
8926 the server would core dump on ap_escape_html(NULL). Check both
8927 tables and raise HTTP_INTERNAL_SERVER_ERROR with a log message
8928 if Location isn't set. [Doug MacEachern, Ken Coar]
8930 *) Add RULE_EXPAT, the src/lib/ directory structure, and a modified copy
8931 of the Expat 1.0.2 distribution. [Greg Stein]
8933 *) Replace regexec() calls with calls to a new API stub function
8934 ap_regexec(). This solves problems with DSO modules which use the regex
8935 library. [Jens-Uwe Mager <jum helios.de>, Ralf S. Engelschall]
8937 *) Add 'Request_Protocol' special keyword to mod_setenvif so that
8938 environment variables can be set according to the protocol version
8939 (e.g., HTTP/0.9 or HTTP/1.1) of the request. [Ken Coar]
8941 *) Add DSO support for OpenStep (Mach 4.2) platform.
8942 [Ralf S. Engelschall, Rex Dieter <rdieter math.unl.edu>] PR#3997
8944 *) Fix sed regex for generating ap_config_auto.h in src/Configure.
8945 [Jan Gallo <gallo pvt.sk>] PR#3690, PR#4373
8947 *) Switch to /bin/sh5 in APACI on Ultrix and friends to avoid problems with
8948 their brain-dead /bin/sh. [Ralf S. Engelschall] PR#4372
8950 *) Better DSO flags recognition on NetBSD platforms using ELF.
8951 [Todd Vierling <tv pobox.com>] PR#4310
8953 *) Always log months in english format for %t in mod_log_config.
8954 [Petr Lampa <lampa fee.vutbr.cz>] PR#4366, 679
8956 *) Support for server-parsed and multiview-determined ReadmeName and
8957 HeaderName files in mod_autoindex. Removed the restriction on
8958 "/"s in ReadmeName and HeaderName directives since the *sub_req*
8959 routines will deal with the access issues. (It's now possible to
8960 have {site|group|project|customer|...} wide readmes and headers.)
8961 [Raymond S Brand <rsbx rsbx.net>, Ken Coar] PR#1574, 3026, 3529,
8964 *) When stat() fails, don't assume anything about the contents of
8965 the struct stat. [Ed Korthof <ed bitmechanic.com>]
8967 *) It's OK for a semop to return EINTR, just loop around and try
8968 again. [Dean Gaudet]
8970 *) Fix configuration engine re-entrant hangups, which solve a
8971 handful of problems seen with mod_perl <Perl> configuration sections
8972 [Salvador Ortiz Garcia <sog msg.com.mx>]
8974 *) Mac OS and Mac OS X Server now use the appropriate custom layout
8975 by default when building with APACI; allow for platform-specific
8976 variable defaults in configure. [Wilfredo Sanchez]
8978 *) Do setgid() before initgroups() in http_main; some platforms
8979 zap the grouplist when setgid() is called. This was fixed in
8980 suexec earlier, but the main httpd code missed the change.

8989 *) OS/2: Add support for building loadable modules using DLLs.
8992 *) Add iconsdir, htdocsdir, and cgidir to config.layout.

8996 being newer than Configuration so that it is less likely to fail
8997 when using APACI and shadow sources. [Wilfredo Sanchez]
8999 *) PORT: Add initial support for Mac OS (versions 10.0 and
9000 greater). Use Mac OS X Server layout for now. Clean up dyld code
9001 in unix/os.c, and don't install the dyld error handlers, which
9002 are no longer needed in Mac OS. [Wilfredo Sanchez]
9004 *) Rename Rhapsody layout to "Mac OS X Server". Change install
9005 locations to appropriate ones for user-built (as opposed to
9006 system) installs. [Wilfredo Sanchez]
9008 *) Modify mod_autoindex's handling of AddDescription so that the
9009 behaviour matches the documentation. [Ken Coar] PR#1898, 3072.
9011 *) Add functionality to the install-bindist.sh script created by
9012 binbuild.sh to use tar when copying distribution files to the
9013 serverroot. This allows upgrading an existing installation
9014 without nesting the new distribution in the old.
9016 install-bindist.sh now detects the local perl5 path to install
9017 apxs and dbmmanage with proper path to perl interpreter.
9019 Add an install-binsupport target which copies the source files
9020 for apxs and dbmmanage to bindist to allow these scripts to
9021 be properly installed relative to the destination serverroot.

9049 value of the DirectoryIndex directive is a single dot. Also likely
9050 to happen for anyother values of DirectoryIndex that will map back

9134 *) Make {Set,Unset,Pass}Env per-directory instead of per-server.
9137 *) Correct an apparent typo: on the Windows and MPE platforms, the
9138 htpasswd utility was limiting passwords to only 8 characters.
9141 *) EBCDIC platforms: David submitted patches for two bugs in the
9142 MD5 digest port for EBCDIC machines:
9143 a) the htdigest utility overwrote the old contents of the digest file
9144 b) the Content-MD5 header value (ContentDigest directive) was wrong
9145 when the returned file was not converted from EBCDIC, but was a
9146 binary (e.g., image file) in the first place.
9147 [David McCreedy <mccreedy us.ibm.com>]
9149 *) support/htpasswd now permits the password to be specified on the
9150 command line with the '-b' switch. This is useful when passwords
9151 need to be maintained by scripts -- particularly in the Win32
9152 environment. [Ken Coar]
9154 *) Win32: Win32 multiple services patch. Added capability to install and
9155 run multiple copies of apache as individual services.
9158 apache -n apache1 -i -f c:/httpd.conf
9159 Installs apache as service 'apache1' and associates c:/httpd.conf
9162 Starts apache1 service.
9164 Stops apache1 service
9167 apache -n apache2 -i
9168 Installs apache as service 'apache2'. httpd.conf is located under
9169 the default server root (/apache/conf/httpd.conf).
9171 Starts apache2 service.
9174 apache -n apache3 -i -d c:/program files/apache

9184 *) Correct the signed/unsigned character handling for the MD5 routines;
9185 mismatches were causing compilation problems with gcc -pedantic and
9186 in the TPF cross-compilation. [Ken Coar]
9188 *) OS/2: Rework CGI handling to use spawn*() instead of fork/exec, achieving
9189 a roughly 5 fold speed up. [Brian Havard]
9191 *) proxy ftp: instead of using the hardwired string "text/plain" as
9192 a fallback type for files served by the ftp proxy, use the
9193 ap_default_type() function to determine the configured type.
9194 This allows for special configurations like
9195 <Directory proxy:ftp://some.host>
9196 DefaultType gargle/blurb
9198 Additionally, add the Content-Encoding: header to FTP proxy replies
9199 when the encoding is defined (by the AddEncoding directive).
9200 Because it was missing, it was almost impossible to browse compressed
9201 files using the FTP proxy (works now perfectly in Communicator).
9202 The ftp proxy now also returns the Date: and Server: header lines (if not
9203 much else... This code is "somewhat" broken) like normal requests do.
9206 *) Be more smart in APACI's configure script when determining the UID/GID
9207 for User/Group directives and use the determined UID/GID to initialize
9208 the permissions on the proxycachedir.
9209 [Dirk-Willem van Gulik, Ralf S. Engelschall]
9211 *) Changed the forking-prior-to-cleanup in the proxy module to first
9212 check wether it actually needs to collect garbage. This reduces
9213 the number of fork()s from one/request to just the odd one an hour.
9214 [Dirk-Willem van Gulik]

9243 *) M_INVALID needed a value within the scope of METHODS so that unknown
9244 methods can be access controlled. [Roy Fielding] PR#3821
9246 *) Added PassAllEnv; makes server's entire environment available
9247 to CGIs and SSIs executed within directive's scope. [Ken Coar]
9249 *) ap_uuencode() always added two trailing '='s and encoding of
9250 8 bit characters on a machine with signed char may produced
9251 incorrect results. Additionally ap_uuencode() should now
9252 work correctly on EBCDIC platforms.
9253 [Ronald Tschalär <ronald innovation.ch>] PR#3411
9255 *) WIN32: Binary installer now runs the configuration DLL before
9256 the reboot prompt (which is only given if MSVCRT.DLL system
9257 DLL is new or updated). This should avoid the configuration
9258 directory being empty after installation. [Paul Sutton]
9259 PR#3767, 3800, 3827, 3850, 3900, 3953, 3988

9263 the Apache service on NT. [Paul Sutton] PR#3741
9265 *) WIN32: Apache.exe now contains an icon. [Paul Sutton]
9267 *) PORT: Switch back to using fcntl() locking on Linux -- instabilities
9268 have been reported with flock() locking (probably related to kernel
9269 version). [Dean Gaudet] PR#2723, 3531
9271 *) Using APACI, the main config file (usually httpd.conf) was

9282 *) ap_isxdigit was somehow neglected when adding the ap_isfoo() macros
9283 for 8-bit safeness. [Dean Gaudet]
9285 *) PORT: Use -fPIC instead of -fpic on Solaris and SunOS for compiling DSOs
9286 because SPARCs have a small machine-specific maximum size for the Global
9287 Offset Table which is often exceeded when compiling one of the larger
9288 third-party modules with Apache. [Peter Urban <Peter.Urban epfl.ch>] PR#3977
9290 *) Move the directive `ExtendedStatus' in httpd.conf-dist-win _after_ the
9291 DSO/DLL section because it's a directive from mod_status and isn't
9292 available before the DLL of mod_status is loaded.

9307 *) Let APACI's configure script correctly complain for unknown --enable-XXX
9308 and --disable-XXX options. [Ralf S. Engelschall] PR#3958
9310 *) Link the shared core bootstrap program (``Rule SHARED_CORE=yes'') also
9311 against libap.a and use its ap_snprintf() instead of sprintf() to avoid
9312 possible buffer overflows. [Ralf S. Engelschall]
9314 *) Remove no longer used non-API function ap_single_module_init().
9315 [Ralf S. Engelschall]
9317 *) Add Apple's Mac OS X Server Layout "Rhapsody" to config.layout.
9320 *) Add cgidir, htdocsdir, iconsdir variables to Makefile.tmpl in order
9321 to make platform installations easier. [Wilfredo Sanchez]
9323 *) In configure, do not append the target name to the directory path if
9324 the path already contains "apache". [Ralf S. Engelschall]
9326 *) SIGPIPE is now ignored by the server core. The request write routines
9327 (ap_rputc, ap_rputs, ap_rvputs, ap_rwrite, ap_rprintf, ap_rflush) now
9328 correctly check for output errors and mark the connection as aborted.
9329 Replaced many direct (unchecked) calls to ap_b* routines with the
9330 analogous ap_r* calls. [Roy Fielding]
9332 *) Enhanced mod_rewrite's mapfile handling: The in-core cache for text and
9333 DBM format mapfiles now uses a 4-way hash table with LRU functionality.
9334 Furthermore map lookups for non-existent keys are now cached as well.
9335 Additionally "txt" maps are now parsed with simple string functions
9336 instead of using ap_pregcomp(). As a side effect a bug that prevented
9337 the usage of keys containing the "," character was fixed.
9338 The changes drastically improve the performance when large rewrite maps
9340 [Michael van Elst <mlelstv serpens.swb.de>, Lars Eilebrecht] PR#3160
9342 *) Added ap_sub_req_method_uri() for doing a subrequest with a method
9343 other than GET, and const'd the definition of method in request_rec.
9346 *) Use proper pid_t type for saving PIDs in alloc.c. [John Bley]
9348 *) Replaced use of WIN32 define with HAVE_DRIVE_LETTERS to indicate
9349 when the OS allows a DOS drive letter within pathnames. [Brian Havard]
9351 *) Add %V to mod_log_config, this logs the hostname according to the
9352 UseCanonicalName setting (this is the pre-1.3.4 behaviour of
9353 %v). Useful for mass vhosting. [Tony Finch <dot dotat.at>]
9355 *) Add support for \n and \t to mod_log_config, can be used to produce
9356 more reliable logs with multiline entries. [Tony Finch <dot dotat.at>]
9358 *) Fixed a few compiler nits. [John Bley <jbb6 acpub.duke.edu>]
9360 *) Added informative error messages for failed munmap() and fseek() calls
9361 in http_core.c. [John Bley, Roy Fielding]
9363 *) Added some informative error messages for some failed malloc()
9364 calls. [John Bley <jbb6 acpub.duke.edu>, Jim Jagielski]
9366 *) OS/2 ap_os_canonical_filename()'s behaviour is improved: ap_assert()
9367 is removed. This allows <Directory proxy:*> directives to work and
9368 prevents invalid requests from killing the process.
9369 [Brian Havard <brianh kheldar.apana.org.au>]
9371 *) Reorganised FAQ document.
9372 [Joshua Slive <slive finance.commerce.ubc.ca>] PR#2497
9374 *) src/support/: The ApacheBench benchmark program was overhauled by
9375 David N. Welton: you can now have it generate an HTML TABLE, presumably
9376 for integration into other HTML sources. David updated the ab man page
9377 as well and added some missing descriptions. Thanks!
9378 [David N. Welton <davidw prosa.it>]
9380 *) Win32: The filename validity checker now allows filenames containing
9381 characters in the range 0x80 to 0xff (for example accented characters).
9382 [Paul Sutton] PR#3890
9384 *) Added conditional logging based upon environment variables to
9385 mod_log_config. mod_log_referer and mod_log_agent
9386 are now deprecated. [Ken Coar]
9388 *) Allow apache acting as a proxy server to relay the real
9389 reason of a failure to a client rather than the "internal
9390 server error" it does currently. The general exposure mechanism
9391 can be triggered by any module by setting the "verbose-error-to"
9392 note to "*"; this allows more than just proxy errors to be exposed.
9393 [Cliff Skolnick, Roy Fielding, Martin Kraemer] Related to PR#3455, 4086
9395 *) Moved man pages for ab and apachectrl to section 8.
9396 [Wilfredo Sanchez, Roy Fielding]
9398 *) Added -S option to install.sh so that options can be passed to
9399 strip on some platforms. [Ralf S. Engelschall, Wilfredo Sanchez]
9401 *) Tweak modules Makefile generated by Configure so that it handles
9402 the test case of no modules being selected. [<chaz reliant.com>]
9404 *) Added a <LimitExcept method ...> sectioning directive that allows
9405 the user to assign authentication control to any HTTP method that
9406 is *not* given in the argument list; i.e., the logical negation
9407 of the <Limit> directive. This is particularly useful for controlling
9408 access on methods unknown to the Apache core, but perhaps known by
9409 some module or CGI script. [Roy Fielding, Tony Finch]
9411 *) Prevent apachectl from complaining if the PIDFILE exists but
9412 does not contain a process id, as might occur if the server is
9413 being rapidly restarted. [Wilfredo Sanchez]
9415 *) Win32: Add global symbols missing from ApacheCore.def. [Carl Olsen]
9417 *) Entity tag comparisons for If-Match and If-None-Match were not being
9418 performed correctly -- weak tags might cause false positives. Also,
9419 strong comparison wasn't properly enforced in all cases.
9420 [Roy Fielding, Ken Coar, Dean Gaudet] PR#2065, 3657
9422 *) OS/2: Supply OS/2 error code instead of errno on semaphore errors.
9425 *) Work around a bug in Lynx regarding its sending "Negotiate: trans"
9426 even though it doesn't understand TCN. [Koen Holtman, Roy Fielding]
9428 *) Added ap_size_list_item(), ap_get_list_item(), and ap_find_list_item()
9429 to util.c for parsing an HTTP header field value to extract the next
9430 list item, taking into account the possible presence of nested comments,
9431 quoted-pairs, and quoted-strings. ap_get_list_item() also removes
9432 insignificant whitespace and lowercases non-quoted tokens.
9433 [Roy Fielding] PR#2065
9435 *) proxy: The various calls to ap_proxyerror() can return HTTP/1.1 status
9436 code different from 500. This allows the proxy to, e.g., return
9437 "403 Forbidden" for ProxyBlock'ed URL's. [Martin Kraemer] Related to PR#3455
9439 *) Fix ordering of language variants for the case where the traditional
9440 negotiation algorithm is being used with multiple language variants
9441 and no Accept-Language. [James Treacy <treacy debian.org>] PR#3299, 3688
9443 *) Do not round the TCN quality calculation to 5 decimal places,
9444 unlike RFC 2296, because the calculation might need 12 decimal places
9445 to get the right result. [Roy Fielding]
9447 *) Remove unused code to disable transparent negotiation when
9448 negotiating on encoding only, as we now handle encoding too
9449 (though this is nonstandard for TCN), remove charset=ISO-8859-1
9450 fiddle from the fiddle-averse RVSA comparison, and fix bugs in
9451 some debugging statements within mod_negotiation. [Koen Holtman]
9453 *) Fixed a rare memory corruption possibility in mod_dir if the index
9454 file is negotiable and no acceptable variant can be found.
9455 [Dean Gaudet, Roy Fielding, Martin Kraemer]
9457 *) Win32: Add new config directive, ScriptInterpreterSource, to enable
9458 searching the Win32 registry for script interpreters.
9461 *) Win32: The compiled-in default filename for the error log is now
9462 error.log, which matches the default in the distributed httpd.conf.
9465 *) Win32: Any error messages from -i or -u command line options are now
9466 displayed on the console output rather than sent to the error log.
9467 Also the "Running Apache..." message is not output unless Apache is
9468 going to serve requests. [Paul Sutton]
9470 *) Rework the MD5 authentication scheme to use FreeBSD's algorithm,
9471 and use a private significator ('$apr1$') to mark passwords as
9472 being smashed with our own algorithm. Also abstract the password
9473 checking into a new ap_validate_password() routine. [Ken Coar]
9475 *) Win32: The filename validity checker now allows "COM" but refuses
9476 access to "COM1" through "COM4". This allows filenames such
9477 as "com.name" to be served. [Paul Sutton] PR#3769.
9479 *) BS2000: Adapt to the new ufork() system call interface which will
9480 make subtasking easier on the OSD/POSIX mainframe environment.
9483 *) Add a compatibility define for escape_uri() -> ap_escape_uri() to
9484 ap_compat.h. [David White <david persimmon.com>] PR#3725
9486 *) Make NDBM file suffix determination for mod_rewrite more accurate, i.e.
9487 use `.db' instead of `.pag' not only for FreeBSD, but also when
9488 the NDBM library looks like Berkeley-DB based.
9489 [Ralf S. Engelschall] PR#3773

9498 impossible to exploit.) [Rick Perry <perry ece.vill.edu>]
9500 *) Let src/Configure be aware of CFLAGS options starting with plus
9501 signs as it's the case for the HP/UX compiler.
9502 [Doug Yatcilla <yatcilda umdnj.edu>] PR#3681
9504 *) Remove the hard-wire of TAR=tar (we now check for gtar and gnutar first)
9505 and check to see if the tar we wind up with supports '-h'.
9506 [Jim Jagielski] PR#3671
9508 *) A consistent and conservative style for all shell scripts has been
9509 implemented. Basically, all shell string tests use the traditional
9510 hack of 'if [ "x$var" != "x" ]' or 'if [ "x$var" = "xstring" ]'
9511 to protect against bare null variable strings (ie: wrapping both
9512 sides with double quotes and prepending 'x'). 'x' was chosen
9513 because it's more universal and hopefully easier for old shell
9514 prgrammers, as well as being easier to search for in 'vi' (/x\$) :)
9517 *) The status module now prints out both the main server generation as
9518 well as the generation of each process. Also, the vhost info is
9519 printed with '?notable'. [Jim Jagielski]
9521 *) Move src/main/md5c.c to src/ap/ap_md5c.c; it's httpd-neutral
9522 and this makes its functions available to things in src/support.
9525 Changes with Apache 1.3.4
9527 *) Renamed macros status_drops_connection to ap_status_drops_connection
9528 and vestigial scan_script_header to ap_scan_script_header_err,
9529 mostly for aesthetic reasons. [Roy Fielding]
9531 *) The query switch "httpd -S" didn't exit after showing the
9532 vhost settings. That was inconsistent with the other query functions.
9535 *) Moved the MODULE_MAGIC_COOKIE from before the versions and
9536 filename to the end of the STANDARD_MODULE_STUFF. Its
9537 presence at the beginning prevented reporting of the filename
9538 for modules compiled before 1 January 1999. [Ken Coar]
9540 *) SECURITY: ap_os_is_filename_valid() has been added to Win32
9541 to detect and prevent access to special DOS device file names.
9542 [Paul Sutton, Ken Parzygnat]
9544 *) WIN32: Created new makefiles Makefile_win32.txt (normal build)
9545 and Makefile_win32_debug.txt (debug build) that work on Win95.
9546 Run each of the following from the src directory:
9547 nmake /f Makefile_win32.txt # compiles normal build
9548 nmake /f Makefile_win32.txt install # compiles and installs
9549 nmake /f Makefile_win32.txt clean # removes compiled junk
9550 nmake /f Makefile_win32_debug.txt # compiles debug build
9551 nmake /f Makefile_win32_debug.txt install
9552 nmake /f Makefile_win32_debug.txt clean
9555 *) Added binbuild.sh and findprg.sh helpers to make it easier for us
9556 to build binary distributions. [Lars Eilebrecht]
9558 *) IndexOptions SuppressColumnSorting only turned off making
9559 the column headers anchors; you could still change the display
9560 order by manually adding a '?N=A' or similar query string to the
9561 URL. Now SuppressColumnSorting locks in the sort order so
9562 it can't be overridden this way. [Ken Coar]
9564 *) Added IndexOrderDefault directive to supply a default sort order
9565 for FancyIndexed directory listings. [Ken Coar] PR#1699
9567 *) Change the ap_assert macro to a variant that works on all platforms.
9568 [Richard Prinz <richard.prinz cso.net>] PR#2575
9570 *) Make sure under ELF-based NetBSD (now) and OpenBSD (future) we don't
9571 search for an underscore on dlsym() (as it's already the case
9572 for FreeBSD 3.0). [Todd Vierling <tv pobox.com>] PR#2462
9574 *) Small fix for mod_env.html: The module was documented as to be _not_
9575 compiled into Apache per default, although it _IS_ compiled into
9576 Apache per default. [Sim Harbert <sim mindspring.com>] PR#3572
9578 *) Instead of fixing a bug in the generation procedure for config.status (a
9579 backslash was missing) we remove the bug together with it's complete
9580 context because the special cases of the past can now no longer occur
9581 because of the recent magic for the --with-layout default.
9582 [Ralf S. Engelschall] PR#3590
9584 *) Make top-level Makefile aware of a parallel build procedures (make -j) by
9585 making sure the src/support/ tools are _forced_ to be build last (they
9586 depend on other libraries).
9587 [Markus Theissinger <markus.theissinger gmx.de>]
9589 *) Fix installation procedure: Now that os-inline.c is actually used (a
9590 recently fixed bug prevented this) we need to also install os-include.c
9591 in addition to os.h into the PREFIX/include/ location or building of
9592 module DSOs with APXS fails. [Ralf S. Engelschall] PR#3527
9594 *) Added MODULE_MAGIC_COOKIE as the first field in a module structure to
9595 allow us to distinguish between a garbled DSO (or even a file which isn't
9596 an Apache module DSO at all) and a DSO which doesn't match the current
9597 Apache API. [Ralf S. Engelschall] PR#3152
9599 *) Two minor enhancements to mod_rewrite: First RewriteRule now also
9600 supports the ``nocase|NC'' flag (as RewriteCond already does for ages) to
9601 match case insensitive (this especially avoids nasty patterns like
9602 `[tT][eE][sS][tT]'). Second two additional internal map functions
9603 `escape' and `unescape' were added which can be used to escape/unescape
9604 to/from hex-encodings in URLs parts (this is especially useful in
9605 combination with map lookups).
9606 [Magnus Bodin, Ian Kallen, Ralf S. Engelschall]
9608 *) Renamed the macro escape_uri() to ap_escape_uri() which was
9609 forgotten (because it was a macro) in the symbol renaming process.
9610 [Ralf S. Engelschall]
9612 *) Fix some inconsistencies related to the scopes of directives. The only
9613 user visible change is that the directives `UseCanonicalName' and
9614 `ContentDigest' now use the (more correct) `Options' scope instead of
9615 (less correct) `AuthConfig' scope. [Ralf S. Engelschall]
9617 *) Using DSO, the Server token was being mangled. Specifically, the
9618 module's token was being added first before the Apache token. This
9619 has been fixed. [Jim Jagielski]
9621 *) Major overhaul of mod_negotiation.c, part 2.
9622 - properly handle "identity" within Accept-Encoding.
9623 - allow encoded variants in RVSA negotiation and let them appear in
9624 the Alternates field using the non-standard "encoding" tag-list.
9625 - fixed both negotiation algorithms so that an explicitly accepted
9626 encoding is preferred over no encoding if "identity" is not
9627 included within Accept-Encoding.
9628 - added ap_array_pstrcat() to alloc.c for efficient concatenation
9629 of large substring sequences.
9630 - replaced O(n^2) memory hogs in mod_negotiation with ap_array_pstrcat.
9633 *) Major overhaul of mod_negotiation.c, part 1.
9634 - cleanups to mod_negotiation comments and code structure
9635 - made compliant with HTTP/1.1 proposed standard (rfc2068) and added
9636 support for everything in the upcoming HTTP/1.1
9637 revision (draft-ietf-http-v11-spec-rev-06.txt).
9638 - language tag matching also handles tags with more than 2
9640 - empty Accept, Accept-Language, Accept-Charset headers are
9641 processed correctly; previously an empty header would make all
9642 values acceptable instead of unacceptable.
9643 - allowed for q values in Accept-Encoding
9644 - added support for transparent content negotiation (rfc2295 and
9645 rfc2296) (though we do not implement all features in these drafts,
9646 e.g. no feature negotiation). Removed old experimental version.
9647 - implemented 'structured entity tags' for better cache correctness
9648 (structured entity tags ensure that caches which can deal with Vary
9649 will (eventually) be updated if the set of variants on the server
9651 - this involved adding a vlist_validator element to request_rec
9652 - this involved adding the ap_make_etag() function to the global API
9653 - modified guessing of charsets used by Apache negotiation algorithm
9654 to guess 'no charset' if the variant is not a text/* type
9655 - added code to sort multiviews variants into a canonical order so that
9656 negotiation results are consistent across backup/restores and mirrors
9657 - removed possibility of a type map file resolving to another type map
9658 file as its best variant
9659 [Koen Holtman, Roy Fielding, Lars Eilebrecht] PR#3451, 3299, 1987
9661 *) RFC2396 allows the syntax http://host:/path (with no port number)
9662 but the proxy disallowed it (ap_proxy_canon_netloc()).
9663 [David Kristol <dmk bell-labs.com>] PR#3530
9665 *) When modules update/modify the file name in the configfile_t structure,
9666 syntax errors will report the updated name, not the original one.
9667 [Fabien Coelho <coelho cri.ensmp.fr>] PR#3573
9669 *) Correct some filename case assumptions from WIN32 to
9670 CASE_BLIND_FILESYSTEM. [Brian Havard <brianh kheldar.apana.org.au>]
9672 *) For %v log ServerName regardless of the UseCanonicalName
9673 setting (similarly for %p). [Dean Gaudet]
9675 *) Configure was initializing the variables $OSDIR, $INCDIR and $SHELL
9676 rather late (too late for some invocations of TestCompile).
9677 This improves the make environment available to TestCompile and
9678 the *.module scripts. [Martin Kraemer]
9680 *) The hashbang emulation code in ap_execve.c would interpret
9681 #!/hashbang/scripts correctly, but failed to fall back to a
9682 standard shell for scripts which did NOT start with #!
9683 Now SHELL_PATH is started in these cases. [Martin Kraemer]
9685 *) PORT: Added the Cyberguard V2 port [Richard Stagg <stagg lentil.org>]
9688 *) Update APXS manual page: some -q option arguments were missing
9689 and another was incorrect. [Mark Anderson <mda discerning.com>] PR#3553
9691 *) Cleanup the command line options: `-?' was documented to show
9692 the usage list but does it with an error because `?' is not a valid
9693 command. OTOH a lot of users expect `-h' to print such a usage list and
9694 instead are annoyed for ages by our huge unreadable list of directives.
9695 So we now changed the command line options this way:
9697 Intent: we need `-L' to be free, and `-R' for the DSO run-time path is
9698 very similar to the popular linker option.
9700 Intent: while -l gives the small list of modules, -L now gives the
9701 large list of directives implemented by these modules. This is also
9702 consistent with -v (short version info) and -V (large version info).
9704 Intent: it's now the expected option ;-)
9705 The manual page was adjusted accordingly.
9706 [Ralf S. Engelschall] PR#2714
9708 *) Fixed problem of fclose() on an unopened file in suexec if LOG_EXEC
9709 wasn't defined. [Rick Franchuk <rickf transpect.net>]
9711 *) Removed recently introduced bugs and disfigurements in APACI:
9712 o fixed argument line processing: using $args was broken: It was not
9713 initialized and using args="$args $apc_option" and even args="$args
9714 \"$apc_option\"" fails in the second processing round for any arguments
9715 containing whitespaces. The only correct way is to use the construct
9716 "$@" (but not possible here) or iterate _both_ times over the implicit
9717 argument line (no argument to for-loop) which is what we now use.
9718 o make --with-layout=Apache the default without creating
9719 redundancy (copying the --with-layout block in the argument parsing
9720 loop). We achieve this by using the "$@" construct together with the
9721 `set' command to prepend --with-layout=Apache to the command line in
9722 case --with-layout is not used.
9723 o fixed auto-suffix handling now that config.layout exists.
9724 Paths which are auto-suffixed are marked with a trailing plus sign in
9725 config.layout and every path now can be marked this way (not only the
9726 four paths for which we do it currently). Additionally the suffix is
9727 no longer a static one. Instead it's now `/<target>' where <target> is
9728 the argument of the --target option or per default `httpd'.
9729 o allow also tabs (and only spaces) where we match whitespaces
9730 o various fixes and cleanups related to used shell coding style
9731 o made Jim happy by replacing `Written by' with `Initially written by' ;-)
9732 o trimmed output of --help to fit into 80 columns
9733 [Ralf S. Engelschall]
9735 *) Added two new core API functions, ap_single_module_configure() and
9736 ap_single_module_init(), which are now used by mod_so to configure a module
9737 after loading. [Ralf S. Engelschall]
9739 *) PORT: Add defines for USE_FLOCK_SERIALIZED_ACCEPT and
9740 SINGLE_LISTEN_UNSERIALIZED_ACCEPT to NetBSD/OpenBSD section
9741 of ap_config.h to allow serialized accept for multiport listens.
9742 [Roy Fielding, Curt Sampson] PR#3120
9744 *) PORT: Fixed a misplaced #endif for NetBSD/OpenBSD section
9745 of ap_config.h that would skip several defines if DEFAULT_GROUP
9746 was overridden. [Roy Fielding]
9748 *) PORT: The I86 version of DGUX has support for strncasecmp and
9749 strcasecmp, so allow it in ap_config.h. [Amiel Lee Yee] PR#3247
9751 *) Fix ordering of definitions in ap_config.h so that ap_inline is
9752 defined before it might be used. [Victor Khimenko]
9754 *) PORT: Add Dynamic Shared Object (DSO) support for BSDI (v4.0).
9755 [Tom Serkowski <tks bsdi.com>] PR#3453
9757 *) Make generation of src/Configuration.apaci more robust: It failed to
9758 differenciate between modules when one module name was a postfix of
9759 another (e.g. cgi vs. fastcgi). We now check for mod_XXX, libXXX and even
9760 just XXX (think about totally non-standard names like "apache_ssl", too).
9761 [Ralf S. Engelschall] PR#3380
9763 *) In src/Configure remove the SERVER_SUBVERSION support (already deprecated
9764 since 1.3b7) and make whitespace handling more robust (it failed horrible
9765 when whitespaces were present in the arguments of -D options).
9766 [Ralf S. Engelschall] PR#3240
9768 *) Add APACI --shadow=DIR variant (in addition to --shadow). This now first
9769 creates an external package shadow tree in DIR before the local build
9770 shadow tree is generated under DIR. This way one can have the extracted
9771 Apache distribution tree read-only on NFS or CDROM and still build Apache
9772 from these sources. An automatically triggered VPATH-like mechanism is
9773 provided through the TOP variable, too.
9774 [Ralf S. Engelschall, Wilfredo Sanchez <wsanchez apple.com>]
9776 *) Fix negotiation so that a Vary response header is correctly
9777 generated when, for a particular dimension, variants only vary
9778 in having or not having a value for that dimension. [Paul Sutton]
9780 *) Fix negotiation so that we prefer an encoded variant over an
9781 unencoded variant if the user-agent explicitly says it can
9782 accept that encoding. Previously we always preferred the unencoded
9784 [Paul Ausbeck <paula alumni.cse.ucsc.edu>, Paul Sutton] PR#3447
9786 *) Fix APXS tool: query variables LIBS_SHLIB and TARGET were not recognized
9787 and the usage page was inconsistent with the functionality and manpage.
9788 [Ralf S. Engelschall]
9790 *) Allow special options -Wc,xxx and -Wl,xxx on APXS compile/link command.
9791 They can occur multiple times and their arguments (`xxx') are passed AS
9792 IS to the compiler/linker command. [Ralf S. Engelschall]
9794 *) Fixed possible (but harmless in practice) bug in the DBM lookup
9795 procedure of mod_rewrite: very long keys were truncated.
9796 [Ralf S. Engelschall]
9798 *) Added a generic --with-layout=[FILE:]ID option. ID here is a layout
9799 identifier, currently "Apache" and "GNU" are pre-defined in the file
9800 config.layout. Custom layouts are possible by using FILE:ID as the
9801 argument where the layout ID is taken from FILE.
9803 The config.layout file consists of <Layout ID>..</Layout> sections
9804 where inside those sections "path_variable: path_value" pairs can be
9805 specified. These lines are converted to path_variable='path_value'.
9807 *) Add a DefaultLanguage directive so that files missing a language
9808 extension (e.g., .fr, .de) can be labelled as being some other
9809 default language. DefaultLanguage can appear in <Directory> and
9810 <Files> containers as well as .htaccess files. [Paul Sutton]
9813 *) Fix TARGET configuration when configuring and installing using
9814 APACI configure. TARGET now defines the basename of the configuration
9815 file, startup script, manual page, etc. log_error_core() now reports
9816 the server binary name given by argv[0]. TARGET can now also be defined
9817 with --target=TARGET parameter passed to APACI configure.
9818 [Ralf Engelschall, Randy Terbush]
9820 *) mod_include.c:handle_perl() now properly tests for OPT_INCNOEXEC
9821 rather than OPT_INCLUDES [Rainer Schoepf <schoepf uni-mainz.de>]

9843 *) Fallback to native compilers for IRIX-32 platform. It seems that
9844 a gcc 2.8.1 compiled apache is logging client addresses with all
9845 bits set (255.255.255.255). This is the second such problem caused
9846 by gcc 2.8.1 compiler. The first being broken semaphore locking.

9925 in the Configuration[.apaci] file. Two special and important variants are
9926 supported for the option argument: first BEGIN:foo which permutes module
9927 mod_foo with the begin of the module list, i.e. it `moves' the module to
9928 the begin of the list (gives it lowest priority). And second foo:END
9929 which permutes mod_foo with the end of the module list, i.e. it `moves'

9973 function which is normally called for static content. This allows
9974 you to override a specific handler. [Marc Slemko]
9976 *) Further simplify checking for absolute paths by replacing an
9977 hard-coded syntax check with a call to a routine we already created to
9978 do this. [Ken Parzygnat <kparz raleigh.ibm.com>] PR#2976, 3074
9980 *) Log an error if we encounter a malformed "require" directive
9981 in mod_auth if we know that we know that no other module can
9982 deal with it. [Marc Slemko]
9984 *) Remove ap_private_extern method of hiding conflicting symbols
9985 on the NEXT platform because it is not correct for all versions,
9986 and the versions for which it is correct are unknown.
9987 [Wilfredo Sanchez <wsanchez apple.com>]
9989 *) Fix inheritance of IndexOptions NameWidth and remove unintended
9990 restriction on +NameWidth, +IconHeight, and +IconWidth. [Ken Coar]
9992 *) Fix per-directory config merging for cases in which a 500 error
9993 is encountered in an .htaccess file somewhere down the tree.
9996 *) Minor performance improvement to ap_escape_html(). [Roy Fielding]
9998 *) Fixed a segmentation violation in mod_proxy when a response is
9999 non-cachable. [Roy Fielding, traced by Doug Bloebaum]. PR#2950, 3056
10001 Changes with Apache 1.3.3
10003 *) Added a complete implementation of the Expect header field as
10004 specified in rev-05 of HTTP/1.1. Disabled the 100 Continue
10005 response when we already know the final status, which is mighty
10006 useful for PUT responses that result in 302 or 401. [Roy Fielding]
10008 *) Remove extra trailing whitespace from the getline results as part
10009 of the protocol processing, which is extra nice because it works
10010 between continuation lines, is almost no cost in the normal case
10011 of no extra whitespace, and saves memory. [Roy Fielding]
10013 *) Added new HTTP status codes and default response bodies from the
10014 revised HTTP/1.1 (307, 416, 417), WebDAV (102, 207, 422, 423), and
10015 HTTP Extension Framework (510) specifications. Did not add the
10016 WebDAV 424 and 425 codes because they are bogus. We don't use any
10017 of these codes yet, but they are now available to 3rd-party modules.
10020 *) Fix a possible race condition between timed-out requests and the
10021 ap_bhalfduplex select that might result in an infinite loop on
10022 platforms that do not validate the descriptor. [Roy Fielding]
10024 *) WIN32: Add "-k shutdown" and "-k restart" options to signal a
10025 running Apache server [Paul Sutton]
10027 *) Fix mod_autoindex bug where directories got a size of "0k" instead
10028 of "-". [Martin Plechsmid <plechsmi karlin.mff.cuni.cz>, Marc Slemko]
10031 *) PORT: DRS 6000 machine. [Paul Debleecker <pdebleecker jetair.be>]
10033 *) Add the server signature text (from the core ServerSignature directive)
10034 to the list of envariables available to scripts, SSI, and the like.
10037 *) PORT: Fix sys/resource.h handling for SCO 3.x platform.
10038 [M. Laak <maert proinv.ee>] PR#3108
10040 *) Fallback from sysconf-based to plain HZ-based `ticks per second'
10041 calculation in mod_status for all systems which don't have POSIX
10042 sysconf() (like UTS 2.1) and not only for the NEXT platform.
10043 [Dave Dykstra <dwd bell-labs.com>] PR#3055
10045 *) Fix `require ...' directive parsing in mod_auth, mod_auth_dbm and
10046 mod_auth_db by using ap_getword_white() (which uses ap_isspace())
10047 instead of ap_getword(..., ' ') (which parses only according to spaces
10048 but not tabs). [James Morris <jmorris intercode.com.au>,
10049 Ralf S. Engelschall] PR#3105
10051 *) Fix the SERVER_NAME variable under sub-request situations (where
10052 `UseCanonicalName off' is used) like CGI's called from SSI pages or
10053 RewriteCond variables by adopting r->hostname to sub-requests.
10054 [James Grinter <jrg blodwen.demon.co.uk>] PR#3111

10065 *) Quote paths in default configuration files. [Wilfredo Sanchez]
10067 *) PORT: Remove extra HAVE_SYS_RESOURCE_H define for RHAPSODY since
10068 it is now taken care of properly by the header file tests.
10069 [Wilfredo Sanchez <wsanchez apple.com>]
10071 *) Fix problem with scripts and filehandle inheritance on Win32.
10072 [Ken Parzygnat <kparz raleigh.ibm.com>] PR#2884, 2910
10074 *) Win32 name canonicalisation could end up using the server's
10075 working directory to fill in some blanks. [Ken Parzygnat
10076 <kparz raleigh.ibm.com>] PR#3001
10078 *) Correct invalid assumption by ap_sub_req_lookup_file() that all
10079 absolute paths begin with "/" -- because they don't on Win32.
10080 [Ken Parzygnat <kparz raleigh.ibm.com>] PR#2976, 3074
10082 *) Add [REDIRECT_]VARIANTS environment variable to mod_speling
10083 so that ErrorDocument 300 processors can reformat the list
10084 if desired. [Ken Coar] PR#2859
10086 *) Add +/- incremental prefixes to IndexOptions keywords, and
10087 enable merging of multiple IndexOptions directives. [Ken Coar]
10089 *) PORT: Allow GuessOS to recognize Unixware 7.0.1 [Steve Cameron
10090 <steve.cameron compaq.com>]
10092 *) Reconstructed the loop through multiple htaccess file names so
10093 that missing files are not confused with unreadable files.
10096 *) The ap_pfopen and ap_pfdopen routines were failing to protect the
10097 errno on an error, which leads to one error being mistaken for
10098 another when reading non-existent .htaccess files.
10101 *) OS/2: The new header tests get things right, need to update
10102 ap_config.h. [Brian Havard]
10104 *) The Perl %ENV hash will now be setup by default when using the
10105 mod_include `perl' command [Doug MacEachern]

10113 *) Correct comment in mod_log_config.c about its internals.
10114 [Elf Sternberg <elf halcyon.com>]
10116 *) Avoid possible line overflow in Configure: Use an awkfile to
10117 handle the creation of modules.c [Jim Jagielski]
10119 Changes with Apache 1.3.2
10121 *) Fix bug in ap_remove_module(), which caused problems for dso's
10122 who were the top_module. [Doug MacEachern]
10124 *) Add support for Berkeley-DB/2.x (in addition to Berkeley-DB/1.x) to
10125 mod_auth_db to both be friendly to users who wants to use this version
10126 and to avoid problems under platforms where only version 2.x is present.
10127 [Dan Jacobowitz <drow false.org>, Ralf S. Engelschall]
10129 *) When using ap_log_rerror(), make the error message available to the
10130 *ERROR_NOTES envariables by default. [Ken Coar]
10132 *) BS2000 platform only: get rid of the nasty BS2000AuthFile.
10133 You now must define a BS2000Account name for the server User.
10134 This has fewer security implications than the old approach.
10137 *) Fix SHARED_CORE feature for HPUX platform: We now use extension `.sl'
10138 instead of `.so' and `SHLIB_PATH' instead of `LD_LIBRARY_PATH' on this
10139 platform to make the braindead HPUX linker happy. Notice, for the module
10140 DSOs we don't have to use this, because these are loaded manually (and
10141 not via HPUX' dld). [Ralf S. Engelschall] PR#2905, PR#2968
10143 *) Remove 64 thread limit on Win32.
10144 [Bill Stoddard <stoddard raleigh.ibm.com>]
10146 *) Remove redundant substitutions in top-level Makefile.tmpl.
10147 [Ralf S. Engelschall]
10149 *) Fix APACI's `Group' configuration adjustment - especially for Linux
10150 platforms where `nogroup' exists in /etc/group. [Ralf S. Engelschall]
10152 *) Make PrintPath work generically instead of having one version
10153 strictly for OS/2. [Jim Jagielski, Brian Havard]
10155 *) Fix the recently introduced C header file checking: We now use the C
10156 pre-processor pass only (and no longer the complete compiler pass) to
10157 determine whether a C header file exists or not. Because only this way
10158 we're safe against inter-header dependencies (which caused horrible
10159 portability problems). The only drawback is that we now have a CPP
10160 configuration variable which has to be determined first (we do a similar
10161 approach as GNU Autoconf does here). When all fails the user still has
10162 the possibility to override it manually via APACI or src/Configuration.
10163 As a fallback for the header check itself we can directly check the
10164 existance of the file under /usr/include, too.
10165 [Ralf S. Engelschall] PR#2777
10167 *) PORT: Added RHAPSODY (Mac OS X Server) support. MAP_TMPFILE defined
10168 as an alternate mechanism for mmap'd shared memory for RHAPSODY.
10169 ap_private_extern defined to hide symbols that conflict with loaded
10170 dynamic libraries on the NEXT and RHAPSODY platforms.

10186 [Jeff Stewart <jws purdue.edu>] PR#2790
10188 *) Add some more LIBS for the SCO5 platform which are needed for the already
10189 used -lprot. It's actually a bug in SCO5, of course.
10190 [Ronald Record <rr sco.com>] PR#2533
10192 *) Fix documentation of ProxyPass/ProxyPassReverse according to the
10193 trailing slash problem. [Jon Drukman <jsd gamespot.com>] PR#2933
10195 *) Remove `-msym' option from LDFLAGS_SHLIB for the Digital UNIX (OSF/1)
10196 platform, because it's only supported under version 4.0 and higher. But
10197 because our GuessOS is still unaware of Digital UNIX versions and the
10198 -msym is just to optimize the DSO statup time a little bit it's safe and
10199 best when we leave it out now. [Ralf S. Engelschall] PR#2969
10201 *) Fix the ap_log_error_old(), ap_log_unixerr() and ap_log_printf()
10202 functions: First all three functions no longer fail on strings containing
10203 "%" chars and second ap_log_printf() no longer does a double-formatting
10204 (instead it directly passes through the message to be formatted to the
10205 real internal formatting function). [Ralf S. Engelschall] PR#2941
10207 *) Allow "Include" directives anywhere in the server config
10208 files (but not .htaccess files). [Ken Coar] PR#2727
10210 *) The proxy was refusing to serve CONNECT requests except to
10211 port 443 (https://) and 563 (snews://). The new AllowCONNECT
10212 directive allows the configuration of the ports to which a
10213 CONNECT is allowed. [Sameer Parekh, Martin Kraemer]
10215 *) mod_expires will now act on content that is not sent from a file
10216 on disk. Previously it would never add an Expires: header to
10217 any response that did not come from a file on disk; the only
10218 case where it still doesn't (and can't) add one for that type of
10219 content is if you are using a modification date based setting.
10220 [Marc Slemko, Paul Phillips <paulp go2net.com>]
10222 *) Problems encountered during .htaccess parsing or CGI execution
10223 that lead to a "500 Server Error" condition now provide explanatory
10224 text (in the *ERROR_NOTES envariable) to ErrorDocument 500 scripts.
10227 *) Add NameWidth keyword to IndexOptions directive so that the
10228 width of the filename column is customisable. [Ken Coar, Dean Gaudet]
10231 *) Recognize lowercase _and_ uppercase `uname' results under
10232 SCO OpenServer. [David Coelho <drc ppt.com>]
10234 *) As duplicate "HTTP/1.0 200 OK" lines within the header seem to be
10235 a common problem of (mis-administrated?) IIS servers, make the apache
10236 proxy immune to these errors (and ignore the duplicates, but log
10237 the fact to error_log). [Martin Kraemer], after the proposal in PR#2914
10239 *) The <IfModule and <IfDefine block starting directives now only
10240 allow exactly one argument. Previously, the optional negation
10241 character '!' could be separated by whitespace without a syntax
10242 error being reported, albeit defeating the IfModule functionality
10243 (enclosed directives would ALWAYS be executed). By using the
10244 stricter syntax, these hard-to-track errors can be avoided.
10247 *) Simplify handling of IndexOptions in mod_autoindex -- and BTW
10248 cause the standalone FancyIndexing directive to logically OR
10249 into any existing IndexOptions settings rather than wiping
10250 them out. [Ken Coar]
10252 *) Changes in ftp proxy: make URL parsing simpler by using the
10254 + Add display of the "current directory" in cases where it's
10255 different from the supplied path (e.g., ftp://user@host/ lives
10256 in /home/user, not in /, therefore clicking on "../" in the
10257 starting directory might send us to /home/).
10258 + When ftp login fails, (esp. when a user name was part of the
10259 URL already), we now return [401 Unauthorized ] to allow the
10260 browser to pop up an authorization dialog. This makes passwords
10261 slightly less visible (they don't appear in the regular log files)
10262 and implements a functionality that other www proxy servers
10266 *) Triggered by the recent "Via:" header changes, the proxy module would
10267 dump core for replies with invalid headers (e.g., duplicate
10268 "HTTP/1.0 200 OK" lines). These errors are now logged and the
10269 core dump is avoided. Also, broken replies are not cached.
10270 [Martin Kraemer] PR#2914
10272 *) new `GprofDir' directive when compiled with -DGPROF, where gprof can
10273 plop gmon.out profile data for each child [Doug MacEachern]
10275 *) Use the construct ``"$@"'' instead of ``$*'' in the generated
10276 config.status script to be immune against arguments with whitespaces.
10277 [Yves Arrouye <yves apple.com>] PR#2866
10279 *) Replace the inlined information grabbing stuff for the configuration
10280 adjustment feature (no --without-confadjust) with calls to a new helper
10281 script `buildinfo.sh' which is both more flexible and already proofed to
10282 be more robust against platform differences. This mainly fixes the
10283 recently occured ``sed: command garbled: ...'' problems.
10284 [Ralf S. Engelschall] PR#2776, PR#2848
10286 *) Make ab.c again pass ``gcc -Wall -Wshadow -Wpointer-arith -Wcast-align
10287 -Wmissing-prototypes -Wmissing-declarations -Wnested-externs -Winline''
10288 without complains after we recently added the POST feature.
10289 [Ralf S. Engelschall]
10291 *) Renamed is_HTTP_xxx() macros to ap_is_HTTP_xxx() name. They are used inside
10292 modules as API functions and we forgot them at the big symbol renaming.
10293 [Ralf S. Engelschall]
10295 *) Remove bad reference to non-existing SERVER_VERSION in mod_rewrite.html
10296 [Youichirou Koga <y-koga jp.FreeBSD.ORG>] PR#2895
10298 *) Dynamically size the filename column of mod_autoindex output.
10301 *) Add the ability to do POST requests to the ab benchmarking tool.
10302 [Kurt Sussman <kls best.com>] PR#2871
10304 *) Bump up MAX_ENV_FLAGS in mod_rewrite.h from the too conservatice limit of
10305 5 to 10 because there are some users out there who always have 5 to 8
10306 variables in one RewriteRule and had to patch mod_rewrite.h for every
10307 release. So 15 should be now more than enough, even for them. (I never
10308 needed more than 4 in my RewriteRules ;-)
10309 [Ralf S. Engelschall]
10311 *) Make the proxy generate and understand Via: headers
10314 *) Change the proxy to use tables instead of array_headers for
10315 the header lines. [Martin Kraemer]
10317 *) Make sure the config.status file is not overridden when just
10318 ``configure --help'' is used. [Ralf S. Engelschall] PR#2844
10320 *) Split MODULE_MAGIC_NUMBER into _MAJOR/_MINOR numbers. This should
10321 provide a way to trace API changes that add functionality but do
10322 not create a compatibility issue for precompiled modules, etc.
10323 See include/ap_mmn.h for more details. [Randy Terbush]
10325 *) Fix suexec installation under `make install root=xxx' situation.
10326 [Ralf S. Engelschall]
10328 *) Extend the output of the -V switch to include the paths of all
10329 compiled-in configuration files, if they were overridden at
10330 compile time, for least astonishment of the user.
10333 *) When READing a request in ExtendedStatus mode, the "old"
10334 vhost, request and client information is not displayed.
10337 *) STATUS is no longer available. Full status information now
10338 run-time configurable using the ExtendedStatus directive.
10341 *) SECURITY: CVE-1999-1199 (cve.mitre.org)
10342 Eliminate O(n^2) space DoS attacks (and other O(n^2)
10343 cpu time attacks) in header parsing. Add ap_overlap_tables(),
10344 a function which can be used to perform bulk update operations
10345 on tables in a more efficient manner. [Dean Gaudet]
10347 *) SECURITY: Added compile-time and configurable limits for
10348 various aspects of reading a client request to avoid some simple
10349 denial of service attacks, including limits on maximum request-line
10350 size (LimitRequestLine), number of header fields (LimitRequestFields),
10351 and size of any one header field (LimitRequestFieldsize). Also added
10352 a configurable directive LimitRequestBody for limiting the size of the
10353 request message body. [Roy Fielding]
10355 *) Make status module aware of DNS and logging states, even if
10356 STATUS not defined. [Jim Jagielski]
10358 *) Fix a problem with the new OS/2 mutexes. [Brian Havard]
10360 *) Enhance mod_speling so that CheckSpelling can be used in
10361 <Directory> containers and .htaccess files. [Ken Coar]
10363 *) API: new ap_custom_response() function for hooking into the
10364 ErrorDocument mechanism at runtime [Doug MacEachern]
10366 *) API: new ap_uuencode() function [Doug MacEachern]
10368 *) API: scan_script_header_err_core() now "public" and renamed
10369 ap_scan_script_header_err_core() [Doug MacEachern]
10371 *) The 'status' module will now show the process pid's and their
10372 state even without full STATUS accounting. [Jim Jagielski]
10374 *) Restore the client IP address to the error log messages, this
10375 was lost during the transition from 1.2 to 1.3. Add a new
10376 function ap_log_rerror() which takes a request_rec * and
10377 formats it appropriately. [Dean Gaudet] PR#2661
10379 *) Cure ap_cfg_getline() of its nasty habit of compressing internal
10380 whitespace in input lines -- including within quoted strings.
10382 but leading and trailing whitespace should continue to be
10383 stripped [Martin Kraemer]
10385 *) Cleanup of the PrintPath/PrintPathOS2 helper functions. Avoid
10386 the ugly use of an env. variable and use command-line args for
10387 alternate $PATH. Make more like advanced 'type's as well.
10390 *) The IRIXN32 Rule was being ignored. Configure now correctly adds
10391 -n32 only if IRIXN32 says to. [Jim Jagielski, Alain St-Denis
10392 <alain.st-denis ec.gc.ca>] PR#2736
10394 *) Clean up a warning in mod_proxy. [Ralf S. Engelschall]
10396 *) Renamed __EMX__ (internal define of the gcc port under OS/2) to OS2
10397 following the same idea as "MSVC vs WIN32". Additionally the src/os/emx/
10398 directory was renamed to src/os/os2/ for consistency.
10399 [Brian Havard, Ralf S. Engelschall]
10401 *) Add new Rule SHARED_CHAIN which can be used to enable linking of DSO
10402 files (here modules) against other DSO files (here shared libraries).
10403 This is done by determining a subset of LIBS which can be safely used for
10404 linking the DSOs, i.e. PIC libs and shared libs. Currently the rule is
10405 disabled for all platforms to avoid problems with this (experimental)
10406 rule. But we provide it now for those people how ran into problems and
10407 want to came out by forcing linking against DSOs.

10410 *) Fix suEXEC start message: Has to be of `notice' level to really get

10424 cause the client to miss the HTTP error response. [Roy Fielding]
10426 *) One more portability fix for APACI shadow tree support: Swap order of awk
10427 and sed in top-level configure script to avoid sed fails on some
10428 platforms (for instance SunOS 4.1.3 and NCR SysV) because of the

10452 Makefile.tmpl: The umask+cp approach didn't work as expected (especially

10716 *) Improve performance of directory listings (mod_autoindex) by comparing
10717 integer keys (last-modified and size) as integers rather than converting
10718 them to strings first. Also use a set of explicit byte tests rather
10719 than strcmp() to check for parent directory-ness of an entry. Oh, and
10720 make sure the parent directory (if displayed) is *always* listed first
10721 regardless of the sort key. Overall performance winnage should be good
10722 in CPU time, instruction cache, and memory usage, particularly for large

10732 *) Add httpd -t (test) option for running configuration syntax tests only.
10733 If something is broken it complains and exits with a return code
10734 non-equal to 0. This can be used manually by the user to check the Apache
10735 configuration after editing and is also automatically used by apachectl
10736 on (graceful) restart command to make sure Apache doesn't die on restarts
10737 because of a configuration which is now broken since the last (re)start.
10738 This way `apachectl restart' can be used inside cronjobs without having
10739 to expect Apache to be falling down. Additionally the httpd -t can be run

10933 substitution takes place, for instance via the following rule:
10934 ``RewriteRule ^myscript$ - [T=application/x-httpd-cgi]'' This was often
10935 requested by users in the past to force a single script without a .cgi
10936 extension and outside any cgi-bin dirs to be executed as a CGI program.
10937 [Ralf S. Engelschall] PR#2254
10939 *) A fix for protocol issues surrounding 400, 408, and
10940 414 responses. [Ed Korthof]
10942 *) Ignore MaxRequestsPerChild on WIN32. [Brian Behlendorf]
10944 *) Fix discrepancy in proxy_ftp.c which was causing failures when
10945 trying to connect to certain ftpd's, such as anonftpd.
10946 [Rick Ohnemus <rick ecompcon.com>]
10948 *) Make mod_rewrite use ap_open_piped_log() for RewriteLog directive's
10949 logfile instead of fiddling around itself with child spawning stuff.
10950 [Ralf S. Engelschall]
10952 *) Made RefererIgnore case-insensitive.
10954 *) Mod_log_agent, mod_log_referer now use ap_open_piped_log for piped logs.
10957 *) Replace use of spawn_child with ap_spawn_child_err_buff, to make everything
10958 "safe" under Win32. In: mod_include.c, mod_mime_magic.c
10961 *) Improve RFC1413 support. [Bob Beck <beck bofh.ucs.ualberta.ca>]
10963 *) Fix support script `dbmmanage': It was unable to handle some sort
10964 of passwords, especially passwords with "0" chars.
10965 [Ralf S. Engelschall] PR#2242
10967 *) WIN32: Clicking on "Last Modified" in a fancy index caused a crash. Fixed.
10968 [Ben Laurie] PR#2238
10970 *) WIN32: CGIs could cause a hang (because of a deadlock in the standard C
10971 library), so CGI handling has been changed to use Win32 native handles
10972 instead of C file descriptors.
10973 [Ben Laurie and Bill Stoddard <wgstodda us.ibm.com>] PR#1129, 1607
10975 *) The proxy cache would store an incorrect content-length in the cached
10976 file copy after a cache update. That resulted in repeated fetching
10977 of the original copy instead of using the cached copy.
10978 [Ernst Kloppenburg <kloppen isr.uni-stuttgart.de>] PR#2094
10980 *) The Makefiles assumed that DSO files are build via $(LD). This
10981 is broken for two reasons: First we never defined at least LD=ld
10982 somewhere to make sure this works (it was silently assumed that most Make
10983 provide a built-in LD definition - ARGL!) and second using the generic LD
10984 variable is not the truth. Instead a special variable named LD_SHLIB is
10985 reasonable because although "ld" is usually the default, the command for
10986 building DSO files can be "libtool" or even "cc" on some systems.
10987 [Ralf S. Engelschall]
10989 *) Replace the AddVersionPlatform directive with ServerTokens which
10990 provides for more control over the format of the Server:
10991 header line. SERVER_SUBVERSION is no longer supported;
10992 all module should use the ap_add_version_component()
10993 API function instead. [Jim Jagielski]
10995 *) Support for the NCR MP/RAS 3.0
10996 [John Withers <withers semi.kcsc.mwr.irs.gov>]
10998 *) The LDFLAGS_SHLIB_EXPORT variable of src/Configuration[.tmpl] was
10999 not retrieved in src/Configure and thus was not useable.
11000 [Ralf S. Engelschall]
11002 *) Various Makefile consistency cleanups:
11003 - make OSDIR also automatically be relative to src/ like INCDIR
11004 - SUBDIRS is now generated in src/Makefile only and not in
11005 Makefile.config because it is a local define for this location.
11006 - remove BROKEN_BPRINTF_FLAGS because is it no longer used inside
11007 any Makefile but make sure that at least the "-K inline" is kept in
11009 - update the "depend" targets in Makefile.tmpl files to use $(OSDIR), too.
11010 - updated the dependencies theirself
11011 - removed not existing SHLIB variable from "clean" targets
11012 - replaced SHLIB_OBJS/SHLIBS_OBJ consistently with OBJS_PIC because OBJS
11013 already exists and OBJS_PIC are also just plain objects and have not
11014 directly to do with "shared" things. The only difference is that they
11015 contain PIC. So OBJS_PIC is the more canonical name.
11016 - Updated the Makefile-dependency lines for OBJS_PIC
11017 - Removed the Makefile-dependency line in Configure to avoid double
11019 - replaced ugly xx-so.o/xx.so-o hack with a clean and consistent usage
11020 of xxx.lo as GNU libtool does with its PIC objects
11021 - reduce local complexity in modules Makefile.tmpl by moving the last
11022 existing target "depend" to the generation section in Configure, too.
11023 - removed the historical $(SPACER) which was used in the past together
11024 with BROKEN_BPRINTF_FLAGS to avoid zig-zags in the build process. This
11025 is no longer needed.
11026 - force the build and run of the gen_xxx programs under main/ as the
11027 first step before building the objects because it looks cleaner
11028 [Ralf S. Engelschall]
11030 *) WIN32: Make Win32 work again after the /dev/null DoS fix.
11033 *) WIN32: Check for buffer overflows in ap_os_canonical_filename.
11036 *) WIN32: Don't force ISAPI headers to finish with \n.
11037 [Jim Patterson <Jim.Patterson Cognos.COM>, Ben Laurie] PR#2060
11039 *) When opening "configuration" files (like httpd.conf, htaccess
11040 and htpasswd), Apache will not allow them to be non-/dev/null
11041 device files. This closes a DoS hole. At the same time,
11042 we use ap_pfopen to open these files to handle timeouts.
11043 [Jim Jagielski, Martin Kraemer]
11045 *) Apache will now log the reason its httpd children exit if they exit
11046 due to an unexpected signal. (It requires a new porting define,
11047 SYS_SIGLIST, which if defined should point to a list of text
11048 descriptions of the signals available. See PORTING.) [Dean Gaudet]
11050 *) WIN32: chdir() doesn't make sense in a multithreaded environment
11051 like WIN32. Before, Win32 CGI's could have had sporadic failures
11052 if a chdir call from one thread was made between another chdir call
11053 and a spawn in another thread. So, for now don't chdir for CGI scripts
11054 in WIN32. The current CGI "spec" is unclear as to whether it's
11055 necessary. Long-term fix is to either serialize the chdir/spawn combo
11056 or use WIN32 native calls to spawn a process. This temp fix was
11057 necessary to remove this as a showstopper for 1.3's release.
11060 *) Cleanup the suEXEC support in APACI and make it more safe:
11061 1. Add big fat hint in INSTALL about risks and to read the
11062 htdocs/manual/suexec.html document before using the suexec-related
11064 2. Make sure the user has at least provided one --suexec-xxxx option
11065 (specifies suEXEC parameters) in addition to --enable-suexec option.
11066 If only --enable-suexec is given APACI stops with a hint to INSTALL
11067 and htdocs/manual/suexec.html documents.
11068 3. Provide two additional --suexec-xxxx options to make the suEXEC
11069 configuration complete (especially for package maintainers who else
11070 had to patch the source tree) by providing ways to configure minimal
11071 UID/GID and safe PATH, too.
11072 [Ralf S. Engelschall]
11074 *) Cleanup of the `configure --shadow' process:
11075 - make sure the configure script creates its temporary files in the
11076 shadow tree to avoid conflicts with parallel configure runs
11077 - removed unnecessary option "-r" from "rm" call for Makefiles
11078 - make sure the configure scripts creates the shadow-wrapper Makefile
11079 only when no shadow trees already exists
11080 - make sure "make distclean" removes the shadow-wrapper Makefile but only
11081 when no more shadow trees exists
11082 - overhauled mkshadow.sh script: now its more IFS-safe and approx. twice
11083 as fast (in the past it needed 70sec, now it runs just 38sec)
11084 - make sure CVS does not complain about the created files
11085 Makefille.<gnutriple> and directories src.<gnutriple>
11086 [Ralf S. Engelschall]
11088 *) Added the ap_add_version_component() API routine and the
11089 AddVersionPlatform core directive. The first allows modules to
11090 declare themselves in the Server response header field value,
11091 augmenting the SERVER_SUBVERSION define in the Configuration file
11092 with run-time settings (more useful in a loadable-module environment).
11093 AddVersionPlatform inserts a comment such as "(UNIX)" or "(Win32)"
11094 into the server version string. [Ken Coar] PR#2056
11096 *) Minor stability tweaks to avoid core dumps in ap_snprintf.
11099 *) Emit the "Accept-Range" header for the default handler.
11100 [Brian Behlendorf] PR#1464
11102 *) Add a note to httpd.conf-dist that apache will on some systems fail
11103 to start when the Group # is set to a negative or large positive value.
11106 *) Make sure the module execution order is correct even when some modules
11107 are loaded under runtime (`LoadModule') via the DSO mechanism:
11108 1. The list of loaded modules is now a dynamically allocated one
11109 and not the original statically list from modules.c
11110 2. The loaded modules are now correctly setup by LoadModule for
11111 later use by the AddModule command.
11112 3. When the DSO mechanism for modules is used APACI's `install'
11113 target now enables all created `LoadModule' lines per default because
11114 this is both already expected by the user _and_ needed to avoid
11115 confusion with the next point and reduces the Makefile.tmpl complexity
11116 4. When the DSO mechanism for modules is used, APACI's `install'
11117 target now additionally makes sure the module list is reconstructed
11118 via a complete `ClearModuleList+AddModule...' entry.
11119 5. The support tool `apxs' now also makes sure an AddModule command
11120 is added in addition to the LoadModule command.
11121 6. The modules.c generation was extended to now contain two
11122 comments to make sure no one is confused by the confusing terminology
11123 of loading/linking (we use load=link+load & link=activate instead of
11124 the obvious load=activate & link=link :-( )
11125 This way now there is no longer a difference under execution time between
11126 statically and dynamically linked modules.
11127 [Ralf S. Engelschall]
11129 *) Fix the generated mod_xxx.c from "apxs -g -f xxx" after the
11130 Big Symbol Renaming. [Ralf S. Engelschall]
11132 *) Add a comment to mod_example.c showing the format of a FLAG command
11133 handler. [Ken Coar]
11135 *) Standardized the time format in mod_status to match that of other
11136 places in the code (e.g. DATE_GMT). PR#1551
11138 *) Fix handling of %Z in timefmt strings for those platforms with no time
11139 zone information in their tm struct. [Paul Eggert <eggert twinsun.com>]
11142 *) Makes mod_rewrite, mod_log_config, mod_status and the ServerSignature
11143 feature compatible with 'UseCanonicalName off' by changing
11144 r->server->server_hostname to ap_get_server_name(). And I changed some
11145 functions which use r->server->port to use ap_get_server_port() instead,
11146 because if there's no Port directive in the config r->server->port is 0.
11149 *) get/set_module_config are trivial enough to be better off inline. Worth
11150 1.5% performance boost. [Dean Gaudet]
11152 *) Fix off-by-one error in ap_proxy_date_canon() in proxy_util.c
11153 when ensuring 'x' is at least 30-chars big. [Jim Jagielski,
11156 *) [BS2000 security] BS2000 needs an extra authentication to initialize
11157 the task environment to the unprivileged User id. Otherwise CGI scripts
11158 would have a way to gain super user access. [Martin Kraemer]
11160 *) Fix debug log messages for BS2000/OSD: instead of logging the whole
11161 absolute path, only log base name of logging source as is done
11162 in unix. [Martin Kraemer]
11164 *) Ronald Tschalaer's Accept-Encoding patch - preserve the "x-" in
11165 the encoding type from the Accept-Encoding header (if it's there)
11166 and use it in the response, as that's probably what it'll be expecting.
11167 [<Ronald.Tschalaer psi.ch>]
11169 *) Fix to mod_alias: translate_alias_redir is dealing with
11170 a URI, not a filename, so the check for drive letters for win32
11171 and emx is not necessary. [Dean Gaudet]
11173 *) WIN32: Allow .cmd as an executable extension.
11174 [Kari Likovuori <Kari.Likovuori mol.fi>] PR#2146
11176 *) Make Apache header files, and some variables, C++ friendly.
11177 [Michael Anderson's <mka redes.int.com.mx>]
11179 *) Child processes can now "signal" (by exiting with a status
11180 of APEXIT_CHILDFATAL) the parent process to abort and
11181 shutdown the server if the error in the child process was
11182 fatal enough. [Jim Jagielski]
11184 *) mod_autoindex's find_itme() was sensitive to MIME type case.
11185 [Jim Jagielski] PR#2112
11187 *) Make sure the referer_log and agent_log entries in the default httpd.conf
11188 file are also adjusted for the actual relative installation paths.
11189 [Ralf S. Engelschall] PR#2175
11191 *) WIN32: Extensive overhaul of the way UNCs are handled. [Ben Laurie]
11193 *) WIN32: Make roots of filesystems (e.g. c:/) work. [Ben Laurie]
11196 *) PORT: Various porting changes to support AIX 3.2, 4.1.5, 4.2 and 4.3.
11197 Additionally the checks for finding the vendor DSO library were moved
11198 from mod_so.c to Configure because first it needs $PLAT etc. and second
11199 mod_so already uses an abstraction layer and does not fiddle with the
11200 vendor functions itself.
11201 [Jens-Uwe Mager, Ralf S. Engelschall]
11203 *) PORT: Some optimization defines for NetBSD
11204 [Jaromir Dolecek <dolecek ics.muni.cz>] PR#2165
11206 *) PORT: Dynamic Shared Object (DSO) support for NetBSD.
11207 [Jaromir Dolecek <dolecek ics.muni.cz>, Ralf S. Engelschall] PR#2158
11209 *) Add Dynamic Shared Object (DSO) support for AIX (at least 4.2 but older
11210 AIX variants should work fine, too. Even AIX 3.x should work). This is
11211 accomplished by using the free DSO emulation code from Jens-Uwe Mager
11212 which we put into a os/unix/os-dso-aix.c file.
11213 [Ralf S. Engelschall]
11215 *) PORT: Fix compiler warnings under AIX >= 4.2 where the manual pages imply
11216 that we should use NET_SIZE_T == int but the include files force size_t.
11217 [Ralf S. Engelschall]
11219 *) Fix two bugs in select() handling in http_main.c.
11222 *) Suppress "error(0)" messages for ap_log_error() when the APLOG_NOERRNO
11223 is unset (as it is in situations like timeouts) where it is unclear
11224 whether errno is set or not. [Martin Kraemer]
11226 *) Just having APACI's localstatedir is too general and not enough for most
11227 of the systems. 1.3b6 again required manual APACI patches by package
11228 maintainers from Red Hat and FreeBSD because for their filesystem layout a
11229 little bit more flexibility in configuring the paths is needed. Hence we
11230 provide three additional configure options (--runtimedir, --logfiledir,
11231 --proxycachedir) which now can be used for more granular adjustments if
11232 --localstatedir is not enough to fit the particular needs. As a nice
11233 side-effect this reduces some subdir fiddling in configure+Makefile.tmpl.
11234 [Ralf S. Engelschall]
11236 *) Make the install root for "make install" in APACI's Makefile overrideable
11237 by package authors. This way we are even more friendly to package
11238 maintainers (especially Debian and Red Hat) who build for the real prefix
11239 via "configure --prefix=/<real>" but use a different local prefix via
11240 "make root=/tmp/apache install" for rolling the package without bristling
11241 the target location on their system.
11242 [Ralf S. Engelschall]
11244 *) Workaround sed limitations in APACI's configure script by now
11245 substituting in chunks of 50 commands (because for instance HPUX's vendor
11246 sed has a limit of max. 98 commands)
11247 [Ralf S. Engelschall] PR#2136
11249 *) Adding SOCKS5 support and fixing existing SOCKS4 support.
11250 [Ralf S. Engelschall] PR#2140
11252 *) Manually fix some symbols which were not renamed to prefix ap_ in the BIG
11253 RENAMING process because they are defined as pre-processor macros instead
11254 of real functions: bputc, bgetc, piped_log_write_fd, piped_log_read_fd
11255 [Ralf S. Engelschall]
11257 *) Workaround braindead AWK's when generating ap_config.h: The split() and
11258 substr() functions cannot be nested under vendor AWK from Solaris 2.6.
11259 [Ralf S. Engelschall] PR#2139
11261 *) Various bugfixes and cleanups for the APACI configure script:
11262 o fix IFS handling for _nested_ situation
11263 o fix Perl interpreter search: take first one found instead of last one
11264 o fix DSO consistency check
11265 o print error messages to stderr instead of stdout
11266 o add install-quiet for --shadow situation to Makefile stub
11267 o reduce complexity by avoiding sed-hacks for rule and module list loops
11268 [Ralf S. Engelschall]
11270 *) Fix DEBUG_CGI situation in mod_cgi.c [David MacKenzie] PR#2114
11272 *) Make sure the input field separator (IFS) shell variable is explicitly
11273 initialized correctly before _every_ `for' loop and also restored after
11274 the loops. [Ralf S. Engelschall]
11276 *) Make sure that "make install" doesn't overwrite the `mime.types' and
11277 `magic' files from an existing Apache installation. Because people often
11278 customize these for own MIME and content types.
11279 [Ralf S. Engelschall]
11281 *) PORT: Dynamic Shared Object (DSO) support for OpenBSD 2.x
11282 [Peter Galbavy, Ralf S. Engelschall] PR#2109
11284 *) Fix the path to the ScoreBoardFile in the install-config target, too.
11285 [Ralf S. Engelschall] PR#2105
11287 *) Let "configure" clear out the users parameters (provided as shell
11288 variables) to avoid side-effects in "src/Configure" when the user
11289 exported them (which is not needed, but some users do it).
11290 [Ralf S. Engelschall] PR#2101
11292 *) Provide backward compatibility from some old src/Configuration.tmpl
11293 parameter names to the canonical Autoconf-style shell variable names. For
11294 instance CFLAGS vs. EXTRA_CFLAGS. The EXTRA_xxx variants are accepted now
11295 but a hint message is displayed. [Ralf S. Engelschall]
11297 *) Make sure that "make install" doesn't overwrite the DocumentRoot and
11298 CGI scripts from an existing Apache installation.
11299 [Ralf S. Engelschall, Jim Jagielski] PR#2084
11301 *) Make `configure --compat' more "compatible" by first
11302 let the libexecdir default to EPREFIX/libexec instead of EPREFIX/bin and
11303 second by making sure the "avoid-bristling-suffix" /apache is not
11304 appended to sysconfdir, datadir, localstatedir and includedir when
11305 --compat is used. [Ralf S. Engelschall, Lars Eilebrecht]
11307 *) NeXT required strdup() in support/logresolve.c
11308 [Francisco Tomei <fatomei sandburg.unm.edu>] PR#2082
11310 *) AIX required sys/select.h in support/ab.c
11311 [Jens Schleusener <Jens.Schleusener dlr.de>] PR#2081
11313 *) Fix the path to the MimeMagicFile in the install-config target, too.
11314 [Ralf S. Engelschall] PR#2089
11316 *) PORT: Added HP-UX 11 patches [Jeff Earickson <jaearick colby.edu>]
11318 *) If you start apache with the -S command line option it will dump
11319 out the parsed vhost settings. This is useful for folks trying
11320 to figure out what is wrong with their vhost configuration.
11321 (Other dumps may be added in the future.) [Dean Gaudet]
11323 *) Add %pA, %pI, and %pp codes to ap_vformatter (and hence ap_bprintf,
11324 ap_snprintf, and ap_psprintf). See include/ap.h for docs.
11327 *) Because /usr/local/apache is the default prefix the ``configure
11328 --compat'' option no longer has to set prefix, again. This way the
11329 --compat option honors a leading --prefix option. [Lars Eilebrecht]
11331 *) PORT: Cast the first argument of dlopen() in ap_os_dso_load()
11332 to `char *' under OSF1 and FreeBSD 2.x where it is defined this way
11333 to avoid "discard const" warnings. [Ralf S. Engelschall]
11335 *) If a specific handler is set for a file yet the request still
11336 ends up being handled by the default handler, log an error
11337 message before handling it. This catches things such as trying
11338 to use SSIs without mod_include enabled. [Marc Slemko]
11340 *) Fix error logging for the startup case where ap_log_error() still uses
11341 stderr as the target. Now the default log level is honored here, too.
11342 [Ralf S. Engelschall]
11344 *) PORT: Make sure some AWK's don't fail in src/Configure with "string too
11345 long" errors when generating the MODULES entry for src/Makefile
11346 [Ben Hyde, Ralf S. Engelschall]
11348 *) Make sure src/Configure doesn't complain about the old directory
11349 /usr/local/etc/httpd/ when APACI is used. [Lars Eilebrecht]
11351 Changes with Apache 1.3b6
11353 *) PORT: Clean up warnings on Ultrix and HPUX. [Ben Hyde]
11355 *) Adding DSO support for the HP/UX platform by emulating the dlopen-style
11356 interface via the similar but proprietary HP/UX shl_xxx-style system
11357 calls. [Ralf S. Engelschall]
11359 *) PORT: Updated UnixWare 2.0.x and 2.1.x entries for DSO support and made
11360 APACI Makefile.tmpl "install" target more robust for sensible UnixWare
11361 Make. [Ralf S. Engelschall]
11363 *) ++++ THE BIG SYMBOL RENAMING ++++
11364 To avoid symbol clashes with third-party code compiled into the server,
11365 we globally applied the prefix "ap_" to the following classes of
11367 - Apache provided general functions (e.g., ap_cpystrn)
11368 - Public API functions (e.g., palloc, bgets)
11369 - Private functions which we can't make static (because of
11370 cross-object usage) but should be (e.g., new_connection)
11371 For backward source compatibility a new header file named compat.h was
11372 created which provides defines for the old symbol names and can be used
11373 by third-party module authors.
11376 *) Added dynamic shared object (DSO) support for SVR4-derivates: The
11377 problem under SVR4 is that there is no command flag to force the linker
11378 to export the global symbols of the httpd executable therewith they are
11379 available to the DSO's. Instead of problematic hacks like creating a
11380 dummy.so file (containing dummy references to all global symbols) the
11381 httpd binary is linked against, we use a clean trick stolen from Perl 5:
11382 Placing the Apache core code itself into a DSO library named libhttpd.so.
11383 This way the global symbols _HAVE_ to be exported and thus are available
11384 to any manually loaded DSO's under runtime. To reduce the impact to the
11385 user to null we go even further and create a stub httpd executable which
11386 automatically keeps track of the DSO library loading itself and thus
11387 hides the complete mechanism from the user. Although the generation of
11388 this DSO library is automatically triggered for platforms which
11389 essentially need it (mostly all SVR4-derivates) it can be also enabled
11390 manually via the Rule SHARED_CORE. This can be interesting in the future
11391 where we perhaps exploit this libhttpd.so mechanism for providing nifty
11392 features like graceful upgrades, or whatever.
11393 [Ralf S. Engelschall, Martin Kraemer]
11395 *) Build the libraries before building the rest of the tools. [Ben Hyde]
11397 *) Add "distclean" target to src/-Makefiles to provide "make distclean" also
11398 inside the src subtree (i.e. for non-APACI users). Following GNU Makefile
11399 conventions while "clean" removes only stuff created by "all" targets,
11400 "distclean" additionally removes the stuff from the configuration
11401 process. This way "make distclean" (hence the name) provides a fresh
11402 source tree as it was for distribution.
11403 [Ralf S. Engelschall]
11405 *) Allow top-level (APACI) Makefile to break on build errors
11406 the same way the src/ subtree Makefiles breaks on them by replacing the
11407 initial APACI sed-subdir-display-kludge with a more clean
11408 variable-passing-solution: variable SDP can optionally hold the subdir
11409 prefix which is consistently used for displaying the subdir movement.
11410 This way even the top-level Makefile can stop correctly on errors as the
11411 user expects. [Ralf S. Engelschall]
11413 *) Fixed ordering of argument checks for RewriteBase directive.
11414 [Todd Eigenschink <eigenstr mixi.net>] PR#2045
11416 *) Change Win32 IS_MODULE to SHARED_MODULE to match Unix' method of
11417 indicating that a module is being compiled for dynamic loading. Also
11418 remove #define IS_MODULE from modules and add SHARED_MODULE define
11419 to the mak/dsp files. [Alexei Kosut]
11421 *) Reduce logging level of "normal" warning messages to APLOG_INFO,
11422 since we are now logging APLOG_WARNING by default. [Roy Fielding]
11424 *) PORT: OS/2 tweak to deal with multiple .exe targets. [Brian Havard]
11426 *) Add documentation file and src/Configuration.tmpl entry for the
11427 experimental mod_mmap_static module. Because although it is and marked as
11428 an experimental one it is distributed and thus should be documented and
11429 prepared for configuration the same way as all others modules.
11430 [Ralf S. Engelschall]
11432 *) Add query (-q) option to apxs support tool to be able to manually query
11433 specific settings from apxs. This is needed for instance when you
11434 manually want to access Apache's header files and you need to assemble
11435 the -I option. Now you can do -I`apxs -q INCLUDEDIR`.
11436 [Ralf S. Engelschall]
11438 *) Now src/Configure uses a fallback strategy for the shared object support
11439 on platforms where no explicit information is available: If a Perl
11440 installation exists we ask it about its shared object support and if it's
11441 the dlopen-style one we shamelessly guess the compiler and linker flags
11442 for creating shared objects from Perls knowledge. Of course, the user is
11443 warning about what we are doing and informed that he should send us
11444 the guessed flags when they work. [Ralf S. Engelschall]
11446 *) Provide APACI --without-support option to be able to disable the build
11447 and installation of the support tools from the src/support/ area.
11448 Although its useful to have these installed per default we should provide
11449 a way to compile and install without them for backward-compatibility.
11450 [Ralf S. Engelschall]
11452 *) Add of the new APache eXtenSion (apxs) support tool for building and
11453 installing modules into an _already installed_ Apache package through the
11454 dynamic shared object (DSO) mechanism [mod_so.c]. The trick here is that
11455 this approach actually doesn't need the Apache source tree. The
11456 (APACI-installed) server package is enough, because this now includes the
11457 Apache C header files (PREFIX/include) and the new APXS tool
11458 (SBINDIR/apxs). The intend is to provide a handy tool for third-party
11459 module authors to build their Apache modules _OUTSIDE_ the Apache source
11460 tree while avoiding them to fiddle around with the totally platform
11461 dependend way of compiling DSO files. The tool supports all ranges of
11462 modules, from trivial ones (single mod_foo.c) to complex ones (like PHP3
11463 which has a mod_php3.c plus a pre-built libmodphp3-so.a) and even can
11464 on-the-fly generate a minimalistic Makefile and sample module for the
11465 first step to provide both a quick success event and to demonstrate the
11466 APXS mechanism to module authors. [Ralf S. Engelschall]
11468 *) Fix core dumps in use of CONNECT in proxy.
11469 [<Rainer.Scherg rexroth.de>] PR#1326, #1573, #1942
11471 *) Modify the log directives in httpd.conf-dist files to use CustomLog
11472 so that users have examples of how CustomLog can be used.
11475 *) Add the new Apache Autoconf-style Interface (APACI) for the top-level of
11476 the Apache distribution tree. Until Apache 1.3 there was no real
11477 out-of-the-box batch-capable build and installation procedure for the
11478 complete Apache package. This is now provided by a top-level "configure"
11479 script and a corresponding top-level "Makefile.tmpl" file. The goal is
11480 to provide a GNU Autoconf-style frontend which is capable to both drive
11481 the old src/Configure stuff in batch and additionally installs the
11482 package with a GNU-conforming directory layout. Any options from the old
11483 configuration scheme are available plus a lot of new options for flexibly
11484 customizing Apache. [Ralf S. Engelschall]
11486 *) The floating point ap_snprintf code wasn't threadsafe.

11498 *) "Options +Includes" wasn't correctly merged if "+IncludesNoExec"
11499 was defined in a parent directory. [Lars Eilebrecht]
11501 *) API: ap_snprintf() code mutated into ap_vformatter(), which is
11502 a generic printf-style routine that can call arbitrary output
11503 routines. Use this to replace http_bprintf.c. Add new routines
11504 psprintf(), pvsprintf() which allocate the exact amount of memory
11505 required for a string from a pool. Use psprintf() to clean up
11506 various bits of code which used ap_snprintf()/pstrdup().
11509 *) PORT: HAVE_SNPRINTF doesn't do anything any longer. This is because
11510 ap_snprintf() has different semantics and formatting codes than
11511 snprintf(). [Dean Gaudet]
11513 *) SIGXCPU and SIGXFSZ are now reset to SIG_DFL at boot-time. This
11514 is necessary on at least Solaris where the /etc/rc?.d scripts
11515 are run with these signals ignored, and "SIG_IGN" settings are
11516 maintained across exec().

11544 *) Allow %2F in two situations: 1) it is in the query part of the URI,
11545 therefore not exposed to %2F -> '/' translations and 2) the request
11546 is a proxy request, so we're not dealing with a local resource anyway.
11547 Without this, the proxy would fail to work for any URL's with
11548 %2f in them (occurs quite often in

11566 *) Reanimated the (still undocumented) proxy receive buffer size directive:
11567 Renamed from ReceiveBufferSize to ProxyReceiveBufferSize because the old

11579 suexec.8, htdigest.1, rotatelogs.8 and logresolve.8. Now all up-to-date
11580 and per default compiled support programs have manual pages - just to
11581 document our stuff a little bit more and to be able to do really
11582 Unix-like installations ;-) [Ralf S. Engelschall]
11584 *) Major cleanups to the Configure script to make it and its generated
11585 Makefiles again readable and maintainable: add SRCDIR option, removed
11586 INCLUDES_DEPTH[0-2] kludge, cleanup of TARGET option, cleanup of
11587 generated sections, consequently added Makefile headers with inheritance
11588 information, added subdir movement messages for easier following where
11589 the build process currently stays (more verbose then standard Make, less
11590 verbose than GNU make), same style to comments in the Configure script,
11591 added Apache license header, fixed a few bugs, etc. [Ralf S. Engelschall]
11593 *) Add the new ApacheBench program "ab" to src/support/: This is derived
11594 from the ZeusBench benchmarking program and can be used to determine the
11595 response performance of an Apache installation. This version is

11601 have been made static, and a few have been marked API_EXPORT. Still
11602 more have been marked CORE_EXPORT and are not intended for general
11603 use by modules. [Doug MacEachern, Dean Gaudet]
11605 *) mod_proxy was not clearing the Proxy-Connection header from
11606 requests; now it does. This did not violate any spec, however
11607 causes poor interactions when you are talking to remote proxies.

11616 *) Performance tweak to mod_log_config. [Dmitry Khrustalev]
11618 *) Clean up some undocumented behavior of mod_setenvif related to
11619 "merging" two SetEnvIf directives when they match the same header
11620 and regex. Document that mod_setenvif will perform comparisons in
11621 the order they appear in the config file. Optimize mod_setenvif by
11622 doing more work at config time rather than at runtime.
11625 *) src/include/ap_config.h now wraps it's #define's with #ifndef/#endif's
11626 to allow for modules to overrule them and to reduce redefinition
11627 warnings [Jim Jagielski]
11629 *) [PORT] For A/UX change the OS-#define for -DAUX to -DAUX3.
11632 *) Making the hard-coded cross-module function call mime_find_ct() (from
11633 mod_proxy to mod_mime) obsolete by making sure the API hook for MIME type
11634 checking is really called even for proxy requests except for URLs with
11635 HTTP schemes (because there we can optimize by not running the type
11636 checking hooks due to the fact that the proxy gets the MIME Content-type
11637 from the remote host later). This change cleans up mod_mime by removing
11638 the ugly export kludge, makes the one-liner file mod_mime.h obsolete, and
11639 especially unbundles mod_proxy and mod_mime. This way they both now can
11640 be compiled as shared objects and are no longer tied together.
11641 [Ralf S. Engelschall]
11643 *) util.c cleanup and speedup. [Dean Gaudet]
11645 *) API: Clarification, pstrndup() will always copy n bytes of the source

11655 *) Performance improvements to invoke_handler().
11656 [Dmitry Khrustalev <dima bog.msu.su>]
11658 *) Added support for building shared objects even for library-style modules
11659 (which are built from more than one object file). This now provides the
11660 ability to build mod_proxy as a shared object module. Additionally
11661 modules like mod_example are now also supported for shared object
11662 building because the generated Makefiles now no longer assume there is at
11663 least one statically linked module. [Ralf S. Engelschall]
11665 *) API: Clarify usage of content_type, handler, content_encoding,
11666 content_language and content_languages fields in request_rec. They
11667 must always be lowercased; and the strings pointed to shouldn't
11668 be modified (you must copy them to modify them). Fix a few bugs
11669 related to this. [Dean Gaudet]
11671 *) API: Clarification: except for RAW_ARGS, all command handlers can
11672 treat the char * parameters as permanent, and modifiable. There
11673 is no need to pstrdup() them. Clean up some needless pstrdup().
11676 *) Now mod_so keeps track of which module shared objects with which names
11677 are loaded and thus avoids multiple loading and unloading and irritating
11678 error_log messages. [Ralf S. Engelschall]
11680 *) Prior to the existence of mod_setenv it was necessary to tweak the TZ
11681 environment variable in the apache core. But that tweaking interferes
11682 with mod_setenv. So don't tweak if the user has specified an explicit
11683 TZ variable. [Jay Soffian <jay cimedia.com>] PR#1888

11694 modules as shared objects. Especially Solaris 2.x, SunOS 4.1, IRIX and
11695 OSF1 support with GCC and vendor compilers was added. This way shared
11696 object support is now provided out-of-the-box for FreeBSD, Linux,
11697 Solaris, SunOS, IRIX and OSF1. In short: On all major platforms!

11700 *) Minor cleanup in http_main -- split QNX and OS2 specific "mmap"
11701 scoreboard code into separate #defines -- USE_POSIX_SCOREBOARD
11702 and USE_OS2_SCOREBOARD. [Dean Gaudet]
11704 *) Fix one more special locking problem for RewriteMap programs in
11705 mod_rewrite: According to the documentation of flock(), "Locks are on
11706 files, not file descriptors. That is, file descriptors duplicated
11707 through dup(2) or fork(2) do not result in multiple instances of a lock,
11708 but rather multiple references to a single lock. If a process holding a
11709 lock on a file forks and the child explicitly unlocks the file, the
11710 parent will lose its lock.". To overcome this we have to make sure the
11711 RewriteLock file is opened _AFTER_ the childs were spawned which is now
11712 the case by opening it in the child_init instead of the module_init API
11713 hook. [Ralf S. Engelschall] PR#1029
11715 *) Change to Location and LocationMatch semantics. LocationMatch no
11716 longer lets a single slash match multiple adjacent slashes in the
11717 URL. This change is for consistency with RewriteRule and
11718 AliasMatch. Multiple slashes have meaning in URLs that they do
11719 not have in (some) filesystems. Location on the other hand can
11720 be considered a shorthand for a more complicated regex, and it
11721 does match multiple slashes with a single slash -- which is
11722 also consistent with the Alias directive.

11725 *) Fix bug with mod_mime_magic causing certain files, including files
11726 of length 0, to result in no response from the server.
11729 *) The Configure script now generates src/include/ap_config.h which
11730 contains the set of defines used when Apache is compiled on a platform.
11731 This file can then be included by external modules before including
11732 any Apache header files in case they are being built separately from
11733 Apache. Along with this change, a couple of minor changes were
11734 made to make Apache's #defines coexist peacefully with any autoconf
11735 defines an external module might have. [Rasmus Lerdorf]
11737 *) Fix mod_rewrite for the ugly API case where <VirtualHost> sections exist
11738 but without any RewriteXXXXX directives. Here mod_rewrite is given no
11739 chance by the API to initialize its per-server configuration and thus
11740 receives the wrong one from the main server. This is now avoided by
11741 remembering the server together with the config structure while
11742 configuring and later assuming there is no config when we see a
11743 difference between the remembered server and the one calling us.
11744 [Ralf S. Engelschall] PR#1790
11746 *) Fixed the DBM RewriteMap support for mod_rewrite: First the support now
11747 is automatically disabled under configure time when the dbm_xxx functions
11748 are not available. Second, two heavy source code errors in the DBM
11749 support code were fixed. This makes DBM RewriteMap's usable again after
11750 a long time of brokenness. [Ralf S. Engelschall] PR#1696
11752 *) Now all configuration files support Unix-style line-continuation via
11753 the trailing backslash ("\") character. This enables us to write down
11754 complex or just very long directives in a more readable way. The

11774 using USE_FCNTL_SERIALIZED_ACCEPT. Users may experiment with
11775 USE_PTHREAD_SERIALIZED_ACCEPT at their own risk, it may speed
11776 up static content only servers. Or it may fail unpredictably.

11779 *) mod_test_util_uri.c created which tests the logic in util_uri.c.
11782 *) API: Rewrite of absoluteURI handling, and in particular how
11783 absoluteURIs match vhosts. Unless a request is a proxy request, a
11784 "http://host" url is treated as if a similar "Host:" header had been
11785 supplied. This change was made to support future HTTP/1.x protocols
11786 which may require clients to send absoluteURIs for all requests.
11788 In order to achieve this change subtle changes were made to the API. In a
11789 request_rec, r->hostlen has been removed. r->unparsed_uri now exists so
11790 that the unmodified uri can be retrieved easily. r->proxyreq is not set
11791 by the core, modules must set it during the post_read_request or
11792 translate_names phase.

11818 *) API: A new source module main/util_uri.c; It contains a routine
11819 parse_uri_components() and friends which breaks a URI into its component
11820 parts. These parts are stored in a uri_components structure called
11821 parsed_uri within each request_rec, and are available to all modules.
11822 Additionally, an unparse routine is supplied which re-assembles the URI
11823 components back to an URI, optionally hiding the username:password@ part
11824 from ftp proxy requests, and other useful routines. Within the structure,
11825 you find on a ready-for-use basis:
11826 scheme; /* scheme ("http"/"ftp"/...) */
11827 hostinfo; /* combined [user[:password]@]host[:port] */
11828 user; /* user name, as in http://user:passwd@host:port/ */

11833 query; /* Everything after a '?' in the path, if present */
11834 fragment; /* Trailing "#fragment" string, if present */
11835 This is meant to serve as the platform for *BIG* savings in

11859 *) Fix long-standing problem with RewriteMap _programs_ under Unix derivates
11860 (like SunOS and FreeBSD) which don't accept the locking of pipes
11861 directly. A new directive RewriteLock is introduced which can be used to
11862 setup a separate locking file which then is used for synchronization.

11880 *) Add new RewriteMap types: First, `rnd' which is equivalent to the `txt'
11881 type but with a special post-processing for the looked-up value: It
11882 parses it into alternatives according to `|' chars and then only one
11883 particular alternative is chosen randomly (this is an essential
11884 functionality needed for balancing between backend-servers when using
11885 Apache as a Reverse Proxy. The looked up value here is a list of
11886 servers). Second, `int' with the built-in maps named `tolower' and
11887 `toupper' which can be used to map URL parts to a fixed case (this is an
11888 essential feature to fix the case of server names when doing mass
11889 virtual-hosting with the help of mod_rewrite instead of using

11893 *) Add a new directive to mod_proxy similar to ProxyPass: `ProxyPassReverse'.
11894 This directive lets Apache adjust the URL in Location-headers on HTTP

11896 mapped area is no longer left on redirects and thus by-passed which is
11897 especially essential when running Apache as a reverse proxy.

12012 now ignores a leading x- when comparing encodings. It also
12013 preserves the encoding the client requests (for example if
12014 it requests x-gzip, then Apache will respond with x-gzip
12015 in the Content-Encoding header).

12043 PR#315, 459, 485, 1433
12045 *) Yet another rearrangement of the source tree.. now all the common
12046 header files are in the src/include directory. The -Imain -Iap
12047 references in Makefiles have been changed to the simpler -Iinclude
12048 instead. In addition to simplifying the build a little bit, this
12049 also makes it clear when a module is referencing something in a
12050 other than kosher manner (e.g., the proxy including mod_mime.h).
12051 Module-private header files (the proxy, mod_mime, the regex library,
12052 and mod_rewrite) have not been moved to src/include; nor have
12053 the OS-abstraction files. [Ken Coar]
12055 *) Fix a bug where r->hostname didn't have the :port stripped
12056 from it. [Dean Gaudet]
12058 *) Tweaked the headers_out table size, and the subprocess_env
12059 table size guess in rename_original_environment(). Added
12060 MAKE_TABLE_PROFILE which can help discover make_table()
12061 calls that use too small an initial guess, see alloc.c.
12064 *) Options and AllowOverride weren't properly merging in the main
12065 server setting inside vhosts (only an issue when you have no
12066 <Directory> or other section containing an Options that affects
12067 a request). Options +foo or -foo in the main_server wouldn't
12068 affect the main_server's lookup defaults. [Dean Gaudet]
12070 *) Variable 'cwd' was being used pointlessly before being set.
12073 *) r->allowed handling cleaned up in the standard modules.
12076 *) Some case-sensitivity issues cleaned up to be consistent with

12079 *) SIGURG doesn't exist everywhere.
12080 [Mark Andrew Heinrich <heinrich tinderbox.Stanford.EDU>]
12082 *) mod_unique_id was erroneously generating a second unique id when
12083 an internal redirect occured. Such redirects occur, for example,
12084 when processing a DirectoryIndex match. [Dean Gaudet]
12086 *) API: table_add, table_merge, and table_set include implicit pstrdup()
12087 of the key and value. But in many cases this is not required
12088 because the key/value is a constant, or the value has been built
12089 by pstrcat() or other similar means. New routines table_addn,
12090 table_mergen, and table_setn have been added to the API, these
12091 routines do not pstrdup() their arguments. The core code and
12092 standard modules were changed to take advantage of these routines.
12093 The resulting server is up to 20% faster in some situations.
12095 Note that it is easy to get code subtly wrong if you pass a key/value
12096 which is in a pool other than the pool of the table. The only
12097 safe thing to do is to pass key/values which are in the pool of
12098 the table, or in one of the ancestors of the pool of the table.
12099 i.e. if the table is part of a subrequest, a value from the main
12100 request's pool is OK since the subrequest pool is a sub_pool of the
12101 main request's pool (and therefore has a lifespan at most as long as
12102 the main pool). There is debugging code which can detect improper
12103 usage, enabled by defining POOL_DEBUG. See alloc.c for more details.
12104 [Dmitry Khrustalev <dima bog.msu.su>, Dean Gaudet]
12106 *) More mod_mime_magic cleanup: fewer syscalls; should handle "files"
12107 which don't exist on disk more gracefully; handles vhosts properly.
12108 Update documentation to reflect the code -- if there's no
12109 MimeMagicFile directive then the module is not enabled.
12112 *) PORT: Some older *nix dialects cannot automatically start scripts
12113 which begin with a #! interpreter line (the shell starts the scripts
12114 appropriately on these platforms). Apache now supports starting of
12115 "hashbang-scripts" when the NEED_HASHBANG_EMUL define is set.
12116 [Martin Kraemer, with code from Peter Wemm <peter zeus.dialix.oz.au>
12119 *) API: "typedef array_header table" removed from alloc.h, folks should
12120 have been writing to use table as if it were an opaque type, but even
12121 some standard modules got this wrong. By changing the definition
12122 to "typedef struct table table" module authors will receive compile
12123 time warnings that they're doing the wrong thing. This change
12124 facilitates future changes with more sophisticated table
12125 structures. Specifically, module authors should be using table_elts()
12126 to get access to an array_header * for the table. [Dean Gaudet]
12128 *) API: Renamed new_connection() to avoid namespace collision with LDAP
12129 library routines. [Ken Coar, Rasmus Lerdorf]
12131 *) WIN32: mod_speling is now available on the Win32 platform.
12134 *) For clarity the following compile time definition was changed:
12136 SAFE_UNSERIALIZED_ACCEPT -> SINGLE_LISTEN_UNSERIALIZED_ACCEPT
12138 Also, for example, HAVE_MMAP would mean to use mmap() scoreboards
12139 and not be a general notice that the OS has mmap(). Now the
12140 HAVE_MMAP/SHMGET #defines strictly are informational that the
12141 OS has that method of shared memory; the type to use for
12142 the scoreboard is a seperate #define (USE_MMAP_SCOREBOARD
12143 and USE_SHMGET_SCOREBOARD). This allows outside modules to
12144 determine if shared memory is available and allows Apache
12145 to determine the best method to use for the scoreboard.
12148 *) PORT: UnixWare 2.1.2 SMP appears to require USE_FCNTL_SERIALIZED_ACCEPT,
12149 as do various earlier versions. It should be safe on all versions.

12174 The choice of flock vs. fcntl was made based on timings which showed that
12175 even on non-NFS, non-exported filesystems fcntl() was an order of

12356 *) ap_snprintf() moved from main/util_snprintf.c to ap/ap_snprintf.c
12357 so the functionality is available to applications other than the
12358 server itself (like the src/support tools). [Ken Coar]
12360 *) ap_slack() moved out of main/util.c into ap/ap_slack.c as part of
12361 the libap consolidation work. [Ken Coar]
12363 *) ap_snprintf() with a len of 0 behaved like sprintf(). This is not
12364 useful, and isn't what the standards require. Now it returns 0

12455 This turns out to be a bug in Winsock - select() doesn't always

12463 for fgetc() and fgets() on SunOS 4.x. [Martin Kraemer, Ben Hyde]
12465 *) It was necessary to distinguish between resources which are
12466 allocated in the parent, for cleanup in the parent, and resources
12467 which are allocated in each child, for cleanup in each child.
12468 A new pool was created which is passed to the module child_init
12469 and child_exit functions; modules are free to register per-child
12470 cleanups there. This fixes a bug with reliable piped logs.
12473 *) mod_autoindex wasn't displaying the ReadmeName file at the bottom
12474 unless it was also doing FancyIndexes, but it displayed the
12475 HeaderName file at the top under all circumstances. It now shows
12476 the ReadmeName file for simple indices, too, as it should.
12479 *) http_core was mmap()ing even in cases where it wasn't going to
12480 read the file. [Ben Hyde <bhyde gensym.com>]
12482 *) Complete rewrite ;-) of mod_rewrite's URL rewriting engine:
12483 Now the rewriting engine (the heart of mod_rewrite) is organized more
12484 straight-forward, first time well documented and reduced to the really
12485 essential parts. All redundant cases were stripped off and processing now
12486 is the same for both per-server and per-directory context with only a
12487 minimum difference (the prefix stripping in per-dir context). As a
12488 side-effect some subtle restrictions and two recently discovered problems
12489 are gone: Wrong escaping of QUERY_STRING on redirects in per-directory
12490 context and restrictions on the substitution URL on redirects.
12491 Additionally some minor source cleanups were done.

12648 *) TestCompile was not passing $LIBS [Dean Gaudet]

12653 *) Add debugging code to alloc.c. Defining ALLOC_DEBUG provides a
12654 rudimentary memory debugger which can be used on live servers with
12655 low impact -- it sets all allocated and freed memory bytes to 0xa5.
12656 Defining ALLOC_USE_MALLOC will cause the alloc code to use malloc()
12657 and free() for each object. This is far more expensive and should
12658 only be used for testing with tools such as Electric Fence and
12659 Purify. See main/alloc.c for more details. [Dean Gaudet]
12661 *) Configure uses a sh trap and didn't set its exitcode properly.
12662 [Dean Gaudet] PR#1159
12664 *) Yet another vhost revamp. Add the NameVirtualHost directive which
12665 explicitly lists the ip:port pairs that are to be used for name-vhosts.
12666 From a given ip:port, regardless what the Host: header is, you can
12667 only reach the vhosts defined on that ip:port. The precedence of
12668 vhosts was reversed to match other precedences in the config --
12669 the earlier vhosts override the later vhosts. All vhost matching was
12670 moved into http_vhost.[ch]. [Dean Gaudet]
12672 *) ap_inline can be used to force inlining. GNUC __attribute__() can
12673 be used for whatever reason is appropriate (i.e. format() warnings
12674 for printf style functions). Both are enabled only with
12675 gcc >= 2.7.x (so that we have fewer support issues with older

12688 *) When booting, apache will now detach itself from stdin, stdout,
12689 and stderr. stderr will not be detached until after the config
12690 files have been read so you will be able to see initial error
12691 messages. After that all errors are logged in the error_log.
12692 This makes it more convenient to start apache via rsh, ssh,
12693 or crontabs. [Dean Gaudet] PR#523
12695 *) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
12696 Also removed the auto-generated link to www.apache.org that was the

12709 *) mod_autoindex improperly counted &escapes; as more than one
12710 character in the description. It also improperly truncated
12711 descriptions that were exactly the maximum length.
12714 *) RedirectMatch was not properly escaping the result (PR#1155). Also
12715 "RedirectMatch /advertiser/(.*) $1" is now permitted.
12718 *) mod_include now uses symbolic names to check for request success
12719 and return HTTP errors, and correctly handles all types of
12720 redirections (previously it only did temporary redirect correctly).
12721 [Ken Coar, Roy Fielding]
12723 *) mod_userdir was modifying r->finfo in cases where it wasn't setting

12737 *) Fixed error in proxy_util.c when looping through multiple host IP
12738 addresses. [Lars Eilebrecht] PR#974
12740 *) If BUFFERED_LOGS is defined then mod_log_config will do atomic
12741 buffered writes -- that is, it will buffer up to PIPE_BUF (i.e. 4k)
12742 bytes before writing, but it will never split a log entry across a
12743 buffer boundary. [Dean Gaudet]
12745 *) API: the short_score record has been split into two pieces, one which
12746 the parent writes on, and one which the child writes on. As part of
12747 this change the get_scoreboard_info() function was removed, and
12748 scoreboard_image was exported. This change fixes a race condition
12749 in file based scoreboard systems, and speeds up changes involving the
12750 scoreboard in earlier 1.3 development. [Dean Gaudet]
12752 *) API: New register_other_child() API (see http_main.h) which allows
12753 modules to register children with the parent for maintenance. It
12754 is disabled by defining NO_OTHER_CHILD. [Dean Gaudet]
12756 *) API: New piped_log API (see http_log.h) which implements piped logs,
12757 and will use register_other_child to implement reliable piped logs
12758 when it is available. The reliable piped logs part can be disabled
12759 by defining NO_RELIABLE_PIPED_LOGS. At the moment reliable piped
12760 logs is only available on Unix. [Dean Gaudet]
12762 *) API: set_last_modified() broken into set_last_modified(), set_etag(), and
12763 meets_conditions(). This allows conditional HTTP selection to be
12764 handled separately from the storing of the header fields, and provides
12765 the ability for CGIs to set their own ETags for conditional checking.
12766 [Ken Coar, Roy Fielding] PR#895

12774 the URL is slightly misspelled. [Martin Kraemer, Alexei Kosut]

12785 Some things (like RewriteMaps) were checked/performed even if they
12786 weren't supposed to be. [Ken Coar] PR #991
12788 *) Implement a new timer scheme which eliminates the need to call alarm() all
12789 the time. Instead a counter in the scoreboard for each child is used to
12790 show when the child has made forward progress. The parent samples this
12791 counter every scoreboard maintenance cycle, and issues SIGALRM if no
12792 progress has been made in the timeout period. This reduces the static
12793 request best-case syscall count to 22 from 29. This scheme is only
12794 used by systems with memory-based scoreboards. [Dean Gaudet]
12796 *) The proxy now properly handles CONNECT requests which are sent
12797 to proxy servers when using ProxyRemote. [Marc Slemko] PR#1024
12799 *) A script called apachectl has been added to the support
12800 directory. This script allows you to do things such as
12801 "apachectl start" and "apachectl restart" from the command
12802 line. [Marc Slemko]
12804 *) Modules and core routines are now put into libraries, which
12805 simplifies the link line tremendously (among other advantages).
12808 *) Some of the MD5 names defined in Apache have been renamed to have
12809 an `ap_' prefix to avoid conflicts with routines supplied by
12810 external libraries. [Ken Coar]
12812 *) Removal of mod_auth_msql.c from the distribution. There are many
12813 other options for databases today. Rather than offer one option,
12814 offer none at this time. mod_auth_msql and other SQL database
12815 authentication modules can be found at the Apache Module Registry.
12816 http://modules.apache.org/ It would be nice to offer a generic
12817 mod_auth_sql option in the near future.
12819 *) PORT: BeOS support added [Alexei Kosut]
12821 *) Configure no longer accepts the -make option, since it creates
12822 Makefile on the fly based on Makefile.tmpl and Configuration.
12824 *) Apache now gracefully shuts down when it receives a SIGTERM, instead
12825 of forcibly killing off all its processes and exiting without
12826 cleaning up. [Alexei Kosut]
12828 *) API: A new field in the request_rec, r->mtime, has been added to
12829 avoid gratuitous parsing of date strings. It is intended to hold
12830 the last-modified date of the resource (if applicable). An
12831 update_mtime() routine has also been added to advance it if
12832 appropriate. [Roy Fielding, Ken Coar]
12834 *) SECURITY: If a htaccess file can not be read due to bad permissions,
12835 deny access to the directory with a HTTP_FORBIDDEN. The previous
12836 behavior was to ignore the htaccess file if it could not be read.
12837 This change may make some setups with unreadable htaccess files
12838 stop working. [Marc Slemko] PR#817
12840 *) Add aplog_error() providing a mechanism to define levels of

12860 object file at link-time that contains the current time
12861 (SERVER_BUILT global const char[]), and include that in the
12862 message. [Ken Coar]
12864 *) Set r->headers_out when sending responses from the proxy.
12865 This fixes things such as the logging of headers sent from
12866 the proxy. [Marc Slemko] PR#659
12868 *) support/httpd_monitor is no longer distributed because the
12869 scoreboard should not be file based if at all possible. Use
12870 mod_status to see current server snapshot.
12872 *) (set_file_slot): New function, allowing auth directives to be
12873 independent of the server root, so the server documents can be
12874 moved to a different directory or machine more easily.
12875 [David J. MacKenzie]
12877 *) If no TransferLog is given explicitly, decline
12878 to log. This supports coexistence with other logging modules,
12879 such as the custom one that UUNET uses. [David J. MacKenzie]
12881 *) Check for titles in server-parsed HTML files.
12882 Ignore leading newlines and returns in titles. The old behavior
12883 of replacing a newline after <title> with a space causes the
12884 title to be misaligned in the listing. [David J. MacKenzie]
12886 *) Change mod_cern_meta to be configurable on a per-directory basis.
12887 [David J. MacKenzie]
12889 *) Add 'Include' directive to allow inclusion of configuration
12890 files within configuration files. [Randy Terbush]
12892 *) Proxy errors on connect() are logged to the error_log (nothing
12893 new); now they include the IP address and port that failed
12894 (*that's* new). [Ken Coar, Marc Slemko] PR#352
12896 *) Various architectures now define USE_MMAP_FILES which causes
12897 the server to use mmap() for static files. There are two
12898 compile-time tunables MMAP_THRESHOLD (minimum number of bytes
12899 required to use mmap(), default is 0), and MMAP_SEGMENT_SIZE (maximum
12900 number of bytes written in one cycle from a single mmap()d object,
12901 default 32768). [Dean Gaudet]
12903 *) API: Added post_read_request API phase which is run right after reading
12904 the request from a client, or right after an internal redirect. It is
12905 useful for modules setting environment variables that depend only on
12906 the headers/contents of the request. It does not run during subrequests
12907 because subrequests inherit pretty much everything from the main
12908 request. [Dean Gaudet]
12910 *) Added mod_unique_id which is used to generate a unique identifier for
12911 each hit, available in the environment variable UNIQUE_ID.
12914 *) init_modules is now called after the error logs have been opened. This
12915 allows modules to emit information messages into the error logs.
12918 *) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
12919 information for case where proxy module is not available. [Marc Slemko]
12921 *) PORT: Apache has need for mutexes to serialize its children around
12922 accept. In prior versions either fcntl file locking or flock file
12923 locking were used. The method is chosen by the definition of
12924 USE_xxx_SERIALIZED_ACCEPT in conf.h. xxx is FCNTL for fcntl(),
12925 and FLOCK for flock(). New options have been added:
12926 - SYSVSEM to use System V style semaphores
12927 - PTHREAD to use POSIX threads (appears to work on Solaris only)
12928 - USLOCK to use IRIX uslock
12929 Based on timing various techniques, the following changes were made
12931 - Linux 2.x uses flock instead of fcntl
12932 - Solaris 2.x uses pthreads
12933 - IRIX uses SysV semaphores -- however multiprocessor IRIX boxes
12934 work far faster if you -DUSE_USLOCK_SERIALIZED_ACCEPT
12935 [Dean Gaudet, Pierre-Yves Kerembellec <Pierre-Yves.Kerembellec vtcom.fr>,
12936 Martijn Koster <m.koster pobox.com>]
12938 *) PORT: The semantics of accept/select make it very desirable to use
12939 mutexes to serialize accept when multiple Listens are in use. But
12940 in the case where only a single socket is open it is sometimes
12941 redundant to serialize accept(). Not all unixes do a good job with
12942 potentially dozens of children blocked on accept() on the same
12943 socket. It's now possible to define SINGLE_LISTEN_UNSERIALIZED_ACCEPT and
12944 the server will avoid serialization when listening on only one socket,
12945 and use serialization when listening on multiple sockets.
12946 [Dean Gaudet] PR#467
12948 *) Configure changes: TestLib replaced by TestCompile, which has
12949 some additional capability (such as doing a sanity check of
12950 the compiler and flags selected); the version of Solaris is now
12951 available via the #define value of SOLARIS2; IRIX n32bit libs
12952 now supported and selectable by new Configuration Rule: IRIXN32;
12953 We no longer default to -O2 optimization. [Jim Jagielski]
12955 *) Updated Configure: Configuration now uses AddModule to specify
12956 module source or binary file location, relative to src directory.
12957 Modules can be dropped into modules/extra, or in their own
12958 directory, and modules can come with a Makefile or Configure can
12959 create one. Modules can add compiler or library information to
12960 generated Makefiles. [Paul Sutton]
12962 *) Source core re-organisation: distributed modules are now in
12963 modules/standard. All other source code is in main. OS-specific
12964 code is in os/{unix,emx,win32} directories. [Paul Sutton]
12966 *) mod_browser has been removed, since it's replaced by mod_setenvif.
12969 *) Fix another long-standing bug in sub_req_lookup_file where it would
12970 happily skip past access checks on subdirectories looked up with
12971 relative paths. (It's used by mod_dir, mod_negotiation,
12972 and mod_include.) [Dean Gaudet]
12974 *) directory_walk optimization to reduce an O(N*M) loop to O(N+M) where
12975 N is the number of <Directory> sections, and M is the number of
12976 components in the filename of an object.
12978 To achieve this optimization the following config changes were made:
12979 - Wildcards (* and ?, not the regex forms) in <Directory>s,
12980 <Files>s, and <Location>s now treat a slash as a special
12981 character. For example "/home/*/public_html" previously would
12982 match "/home/a/andrew/public_html", now it only matches things
12983 like "/home/bob/public_html". This mimics /bin/sh behaviour.
12984 - It's possible now to use [] wildcarding in <Directory>, <Files>
12986 - Regex <Directory>s are applied after all non-regex <Directory>s.
12990 *) Fix a bug introduced in 1.3a1 directory_walk regarding .htaccess files
12991 and corrupted paths. [Dean Gaudet]
12993 *) Enhanced and cleaned up the URL rewriting engine of mod_rewrite:
12994 First the grouped parts of RewriteRule pattern matches (parenthesis!) can
12995 be accessed now via backreferences $1..$9 in RewriteConds test-against
12996 strings in addition to RewriteRules subst string. Second the grouped
12997 parts of RewriteCond pattern matches (parenthesis!) can be accessed now
12998 via backreferences %1..%9 both in following RewriteCond test-against
12999 strings and RewriteRules subst string. This provides maximum flexibility
13000 through the use of backreferences.
13001 Additionally the rewriting engine was cleaned up by putting common
13002 code to the new expand_backrefs_inbuffer() function.
13003 [Ralf S. Engelschall]
13005 *) When merging the main server's <Directory> and <Location> sections into
13006 a vhost, put the main server's first and the vhost's second. Otherwise
13007 the vhost can't override the main server. [Dean Gaudet] PR#717
13009 *) The <Directory> code would merge and re-merge the same section after
13010 a match was found, possibly causing problems with some modules.
13013 *) ip-based vhosts are stored and queried using a hashing function, which
13014 has been shown to improve performance on servers with many ip-vhosts.
13015 Some other changes had to be made to accommodate this:
13016 - the * address for vhosts now behaves like _default_
13017 - the matching process now is:
13018 - match an ip-vhost directly via hash (possibly matches main
13020 - if that fails, just pretend it matched the main server
13021 - if so far only the main server has been matched, perform
13022 name-based lookups (ServerName, ServerAlias, ServerPath)
13023 *only on name-based vhosts*
13024 - if they fail, look for _default_ vhosts
13025 [Dean Gaudet, Dave Hankins <dhankins sugarat.net>]
13027 *) dbmmanage overhaul:
13028 - merge dbmmanage and dbmmanage.new functionality, remove dbmmanage.new
13029 - tie() to AnyDBM_File which will use one of DB_File, NDBM_File or
13030 GDBM_File (-ldb, -lndbm, -lgdbm) (trying each in that order)
13031 - provide better seed for rand
13032 - prompt for password as per getpass(3) (turn off echo, read from
13034 - use "newstyle" crypt based on $Config{osname} ($^O)
13035 - will not add a user if already in database, use new `update' command
13037 - added `check' command to check a users' password
13038 - added `import' command to convert existing password text-files or
13039 dbm files exported with `view'
13040 - more descriptive usage, general cleanup, 'use strict' clean, etc.
13043 *) Added psocket() which is a pool form of socket(), various places within
13044 the proxy weren't properly blocking alarms while registering the cleanup
13045 for its sockets. bclose() now uses pclose() and pclosesocket(). There
13046 was a bug where the client socket was being close()d twice due a still
13047 registered cleanup. [Dean Gaudet]
13049 *) A few cleanups were made to reduce time(), getpid(), and signal() calls.
13052 *) PORT: AIX >= 4.2 requires -lm due to libc changes.
13053 [Jason Venner <jason idiom.com>] PR#667
13055 *) Enable ``=""'' for RewriteCond directives to match against
13056 the empty string. This is the preferred way instead of ``^$''.
13057 [Ralf S. Engelschall]
13059 *) Fixed an infinite loop in mod_imap for references above the server root
13060 [Dean Gaudet] PR#748
13062 *) mod_proxy now has a ReceiveBufferSize directive, similar to
13063 SendBufferSize, so that the TCP window can be set appropriately
13064 for LFNs. [Phillip A. Prindeville]
13066 *) mod_browser has been replaced by the more general mod_setenvif
13067 (courtesy of Paul Sutton). BrowserMatch* directives are still
13068 available, but are now joined by SetEnvIf*, UnSetEnvIf*, and
13069 UnSetEnvIfZero directives. [Ken Coar]
13071 *) "HostnameLookups double" forces double-reverse DNS to succeed in
13072 order for remote_host to be set (for logging, or for the env var
13073 REMOTE_HOST). The old define MAXIMUM_DNS has been deprecated.
13076 *) mod_access overhaul:
13077 - Now understands network/netmask syntax (i.e. 10.1.0.0/255.255.0.0)
13078 and cidr syntax (i.e. 10.1.0.0/16). PR#762
13079 - Critical path was sped up by pre-computing a few things at config time.
13080 - The undocumented syntax "allow user-agents" was removed,
13081 the replacement is "allow from env=foobar" combined with mod_browser.
13082 - When used with hostnames it now forces a double-reverse lookup
13083 no matter what the directory settings are. This double-reverse
13084 doesn't affect any of the other routines that use the remote
13085 hostname. In particular it's still passed to CGIs and the log
13086 without the double-reverse check. Related PR#860.
13089 *) When a large bwrite() occurs (larger than the internal buffer size),
13090 while there is already something in the buffer, apache will combine
13091 the large write and the buffer into a single writev(). (This is
13092 in anticipation of using mmap() for reading files.)
13095 *) In obscure cases where a partial socket write occurred while chunking,
13096 Apache would omit the chunk header/footer on the next block. Cleaned
13097 up other bugs/inconsistencies in error conditions in buff.c. Fixed
13098 a bug where a long pause in DNS lookups could cause the last packet
13099 of a response to be unduly delayed. [Roy Fielding, Dean Gaudet]
13101 *) API: Added child_exit function to module structure. This is called
13102 once per "heavy-weight process" just before a server child exit()'s
13103 e.g. when max_requests_per_child is reached, etc.
13104 [Doug MacEachern, Dean Gaudet]
13106 *) mod_include cleanup showed that handle_else was being used to handle
13107 endif. It didn't cause problems, but it was cleaned up too.
13110 *) mod_cern_meta would attempt to find meta files for the directory itself
13111 in some cases, but not in others. It now avoids it in all cases.
13114 *) mod_mime_magic would core dump if there was a decompression error.
13115 [Martin Kraemer <Martin.Kraemer mch.sni.de>] PR#904
13117 *) PORT: some variants of DGUX require -lsocket -lnsl
13118 [Alexander L Jones <alex systems-options.co.uk>] PR#732
13120 *) mod_autoindex now allows sorting of FancyIndexed directory listings
13121 by the various fields (name, size, et cetera), either in ascending
13122 or descending order. Just click on the column header. [Ken Coar]
13124 *) PORT: Various tweaks to eliminate pointer-int casting warnings on 64-bit
13125 CPUs like the Alpha. Apache still stores ints in pointers, but that's
13126 the relatively safe direction. [Dean Gaudet] PR#344
13128 *) PORT: QNX mmap() support for faster/more reliable scoreboard handling.
13129 [Igor N Kovalenko <infoh mail.wplus.net>] PR#683
13131 *) child_main avoids an unneeded call to select() when there is only one
13132 listening socket. [Dean Gaudet]
13134 *) In the event that the server is starved for idle servers it will
13135 spawn 1, then 2, then 4, ..., then 32 servers each second,
13136 doubling each second. It'll also give a warning in the errorlog
13137 since the most common reason for this is a poor StartServers
13138 setting. The define MAX_SPAWN_RATE can be used to raise/lower
13139 the maximum. [Dean Gaudet]
13141 *) Apache now provides an effectively unbuffered connection for
13142 CGI scripts. This means that data will be sent to the client
13143 as soon as the CGI pauses or stops output; previously, Apache would
13144 buffer the output up to a fixed buffer size before sending, which
13145 could result in the user viewing an empty page until the CGI finished
13146 or output a complete buffer. It is no longer necessary to use an
13147 "nph-" CGI to get unbuffered output. Given that most CGIs are written
13148 in a language that by default does buffering (e.g. perl) this
13149 shouldn't have a detrimental effect on performance.
13151 "nph-" CGIs, which formerly provided a direct socket to the client
13152 without any server post-processing, were not fully compatible with
13153 HTTP/1.1 or SSL support. As such they would have had to implement
13154 the transport details, such as encryption or chunking, in order
13155 to work properly in certain situations. Now, the only difference
13156 between nph and non-nph scripts is "non-parsed headers".
13157 [Dean Gaudet, Sameer Parekh, Roy Fielding]
13159 *) If a BUFF is switched from buffered to unbuffered reading the first
13160 bread() will return whatever remained in the buffer prior to the
13161 switch. [Dean Gaudet]
13163 Changes with Apache 1.3a1
13165 *) Added another Configure helper script: TestLib. It determines
13166 if a specified library exists. [Jim Jagielski]
13168 *) PORT: Allow for use of n32bit libraries under IRIX 6.x
13169 [derived from patch from Jeff Hayes <jhayes aw.sgi.com>]
13172 *) PORT: Some architectures use size_t for various lengths in network
13173 functions such as accept(), and getsockname(). The definition
13174 NET_SIZE_T is used to control this. [Dean Gaudet]
13176 *) PORT: Linux: Attempt to detect glibc based systems and include crypt.h
13177 and -lcrypt. Test for various db libraries (dbm, ndbm, db) when
13178 mod_auth_dbm or mod_auth_db are included. [Dean Gaudet]
13180 *) PORT: QNX doesn't have initgroups() which support/suexec.c uses.
13181 [Igor N Kovalenko <infoh mail.wplus.net>]
13183 *) "force-response-1.0" now only applies to requests which are HTTP/1.0 to
13184 begin with. "nokeepalive" now works for HTTP/1.1 clients. Added
13185 "downgrade-1.0" which causes Apache to pretend it received a 1.0.
13186 [Dean Gaudet] related PR#875
13188 *) API: Correct child_init() slot declaration from int to void, to
13189 match the init() declaration. Update mod_example to use the new
13192 *) added transport handle slot (t_handle) to the BUFF structure
13195 *) get_client_block() returns wrong length if policy is
13196 REQUEST_CHUNKED_DECHUNK.
13197 [Kenichi Hori <ken d2.bs1.fc.nec.co.jp>] PR#815
13199 *) Support the image map format of FrontPage. For example:

13204 ["Darren O'Shaughnessy" <darren aaii.oz.au>] PR#846
13206 *) AddModuleInfo directive for mod_info which allows you to annotate
13207 the output of mod_info. ["Lou D. Langholtz" <ldl usi.utah.edu>]
13209 *) Added NoProxy directive to avoid using ProxyRemote for selected
13210 addresses. Added ProxyDomain directive to cause unqualified
13211 names to be qualified by redirection.
13212 [Martin Kraemer <Martin.Kraemer mch.sni.de>]
13214 *) Support Proxy Authentication, and don't pass the Proxy-Authorize
13215 header to the remote host in the proxy. [Sameer Parekh and
13218 *) Upgraded mod_rewrite from 3.0.6+ to latest officially available version
13219 3.0.9. This upgrade includes: fixed deadlooping on rewriting to same
13220 URLs, fixed rewritelog(), fixed forced response code handling on
13221 redirects from within .htaccess files, disabled pipe locking under
13222 braindead SunOS 4.1.x, allow env variables to be set even on rules with
13223 no substitution, bugfixed situations where HostnameLookups is off, made
13224 mod_rewrite more thread-safe for NT port and fixed problem when creating
13225 an empty query string via "xxx?".
13226 This update also removes the copyright of Ralf S. Engelschall,
13227 i.e. now mod_rewrite no longer has a shared copyright. Instead is is
13228 exclusively copyrighted by the Apache Group now. This happened because
13229 the author now has gifted mod_rewrite exclusively to the Apache Group and
13230 no longer maintains an external version.
13231 [Ralf S. Engelschall]
13233 *) API: Added child_init function to module structure. This is called
13234 once per "heavy-weight process" before any requests are handled.
13235 See http_config.h for more details. [Dean Gaudet]
13237 *) Anonymous_LogEmail was logging on each subrequest.
13238 [Dean Gaudet] PR#421, 868
13240 *) API: Added is_initial_req() which tests if the request being
13241 processed is the initial request, or a subrequest.
13244 *) Extended SSI (mod_include) now handles additional relops for
13245 string comparisons (<, >, <=, and >=). [Bruno Wolff III] PR#41
13247 *) Configure fixed to correctly propagate user-selected options and
13248 settings (such as CC and OPTIM) to Makefiles other than
13249 src/Makefile (notably support/Makefile). [Ken Coar] PR#666, #834
13251 *) IndexOptions SuppressHTMLPreamble now causes the actual HTML of
13252 directory indices to start with the contents of the HeaderName file
13253 if there is one. If there isn't one, the behaviour is unchanged.
13254 [Ken Coar, Roy Fielding, Andrey A. Chernov]
13256 *) WIN32: Modules can now be dynamically loaded DLLs using the
13257 LoadModule/LoadFile directives. Note that module DLLs must be
13258 compiled with the multithreaded DLL version of the runtime library.
13259 [Alexei Kosut and Ben Laurie]
13261 *) Automatic indexing removed from mod_dir and placed into mod_autoindex.
13262 This allows the admin to completely remove automatic indexing
13263 from the server, while still supporting the basic functions of
13264 trailing-slash redirects and DirectoryIndex files. Note that if
13265 you're carrying over an old Configuration file and you use directory
13266 indexing then you'll want to add:
13268 Module autoindex_module mod_autoindex.o
13270 before mod_dir in your Configuration. [Dean Gaudet]
13272 *) popendir/pclosedir created to properly protect directory scanning.
13273 [Dean Gaudet] PR#525
13275 *) AliasMatch, ScriptAliasMatch and RedirectMatch directives added,
13276 giving regex support to mod_alias. <DirectoryMatch>, <LocationMatch>
13277 and <FilesMatch> sections added to succeed <DirectoryMatch ~>, etc...
13280 *) The AccessFileName directive can now take more than one filename.
13281 ["Lou D. Langholtz" <ldl usi.utah.edu>]
13283 *) The new mod_mime_magic can be used to "magically" determine the type
13284 of a file if the extension is unknown. Based on the unix file(1)
13285 command. [Ian Kluft <ikluft cisco.com>]
13287 *) We now determine and display the time spent processing a
13288 request if desired. [Jim Jagielski]
13290 *) mod_status: PID field of "dead" child slots no longer displays
13291 main httpd process's PID. [Jim Jagielski]
13293 *) Makefile.nt added - to build all the bits from the command line:
13294 nmake -f Makefile.nt
13295 Doesn't yet work properly. [Ben Laurie]
13297 *) Default text of 404 error is now "Not Found" rather than the
13298 potentially misleading "File Not Found". [Ken Coar]
13300 *) CONFIG: "HostnameLookups" now defaults to off because it is far better
13301 for the net if we require people that actually need this data to
13302 enable it. [Linus Torvalds]
13304 *) directory_walk() is an expensive function, keep a little more state to
13305 avoid needless string counting. Add two new functions make_dirstr_parent
13306 and make_dirstr_prefix which replace all existing uses of make_dirstr.
13307 The new functions are a little less general than make_dirstr, but
13308 work more efficiently (less memory, less string counting).
13311 *) EXTRA_LFLAGS was changed to EXTRA_LDFLAGS (and LFLAGS was changed
13312 to LDFLAGS) to avoid complications with lex rules in make files.
13313 [Dean Gaudet] PR#372
13315 *) run_method optimized to avoid needless scanning over NULLs in the
13316 module list. [Dean Gaudet]
13318 *) Revamp of (unix) scoreboard management code such that it avoids
13319 unnecessary traversals of the scoreboard on each hit. This is
13320 particularly important for high volume sites with a large
13321 HARD_SERVER_LIMIT. Some of the previous operations were O(n^2),
13322 and are now O(n). See also SCOREBOARD_MAINTENANCE_INTERVAL in
13323 httpd.h. [Dean Gaudet]
13325 *) In configurations using multiple Listen statements it was possible for
13326 busy sockets to starve other sockets of service. [Dean Gaudet]
13328 *) Added hook so standalone_main can be replaced at compile time
13329 (define STANDALONE_MAIN)
13332 *) Lowest-level read/write functions in buff.c will be replaced with
13333 the SFIO library calls sfread/sfwrite if B_SFIO is defined at
13334 compile time. The default sfio discipline will behave as apache
13335 would without sfio compiled in.
13338 *) Enhance UserDir directive (mod_userdir) to accept a list of
13339 usernames for the 'disable' keyword, and add 'enable user...' to
13340 selectively *en*able userdirs if they're globally disabled.
13343 *) If NETSCAPE_DBM_COMPAT is defined in EXTRA_CFLAGS then Apache
13344 will work with Netscape dbm files. (dbmmanage will probably not
13345 work however.) [Alexander Spohr <aspohr netmatic.com>] PR#444
13347 *) Add a ListenBacklog directive to control the backlog parameter
13348 passed to listen(). Also change the default to 511 from 512.
13351 *) API: A new handler response DONE which informs apache that the
13352 request has been handled and it can finish off quickly, similar to
13353 how it handles errors. [Rob Hartill]
13355 *) Turn off chunked encoding after sending terminating chunk/footer
13356 so that we can't do it twice by accident. [Roy Fielding]
13358 *) mod_expire also issues Cache-Control: max-age headers.
13361 *) API: Added kill_only_once option for free_proc_chain so that it won't

13365 *) mod_auth deals with extra ':' delimited fields. [Marc Slemko]
13367 *) Added IconHeight and IconWidth to mod_dir's IndexOptions directive.
13368 When used together, these cause mod_dir to emit HEIGHT and WIDTH
13369 attributes in the FancyIndexing IMG tags. [Ken Coar]
13371 *) PORT: Sequent and SONY NEWS-OS support added. [Jim Jagielski]
13373 *) PORT: Added Windows NT support

13376 Changes with Apache 1.2.6
13378 *) mod_include when using XBitHack Full would send ETags in addition to
13379 sending Last-Modifieds. This is incorrect HTTP/1.1 behaviour.
13380 [Dean Gaudet] PR#1133
13382 *) SECURITY: When a client connects to a particular port/addr, and
13383 gives a Host: header ensure that the virtual host requested can
13384 actually be reached via that port/addr. [Ed Korthof <ed organic.com>]
13386 *) Support virtual hosts with wildcard port and/or multiple ports
13387 properly. [Ed Korthof <ed organic.com>]
13389 *) Fixed some case-sensitivity issues according to RFC2068.
13392 *) Set r->allowed properly in mod_asis.c, mod_dir.c, mod_info.c,
13393 and mod_include.c. [Dean Gaudet]
13395 *) Variable 'cwd' was being used pointlessly before being set.
13398 *) SIGURG doesn't exist on all platforms.
13399 [Mark Andrew Heinrich <heinrich tinderbox.Stanford.EDU>]
13401 *) When an error occurs during a POST, or other operation with a
13402 request body, the body has to be read from the net before allowing
13403 a keepalive session to continue. [Roy Fielding] PR#1399
13405 *) When an error occurs in fcntl() locking suggest the user look up
13406 the docs for LockFile. [Dean Gaudet]
13408 *) table_set() and table_unset() did not deal correctly with
13409 multiple occurrences of the same key. [Stephen Scheck
13410 <sscheck infonex.net>, Ben Laurie] PR#1604
13412 *) send_fd_length() did not calculate total_bytes_sent properly in error
13413 cases. [Ben Reser <breser regnow.com>] PR#1366
13415 *) r->connection->user was allocated in the wrong pool causing corruption
13416 in some cases when used with mod_cern_meta. [Dean Gaudet] PR#1500
13418 *) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
13419 Also removed the auto-generated link to www.apache.org that was the
13420 source of so many misdirected bug reports. [Roy Fielding, Marc Slemko]
13422 *) Multiple "close" tokens may have been set in the "Connection"
13423 header, not an error, but a waste.
13424 [<Ronald.Tschalaer psi.ch>] PR#1683
13426 *) "basic" and "digest" auth tokens should be tested case-insensitive.
13427 [<Ronald.Tschalaer psi.ch>] PR#1599, PR#1666
13429 *) It appears the "257th byte" bug (see
13430 htdocs/manual/misc/known_client_problems.html#257th-byte) can happen
13431 at the 256th byte as well. Fixed. [Dean Gaudet]
13433 *) mod_rewrite would not handle %3f properly in some situations.
13436 *) Apache could generate improperly chunked HTTP/1.1 responses when
13437 the bputc() or rputc() functions were used by modules (such as
13438 mod_include). [Dean Gaudet]
13440 *) #ifdef wrap a few #defines in httpd.h to make life easier on
13441 some ports. [Ralf Engelschall]
13443 *) Fix MPE compilation error in mod_usertrack.c. [Mark Bixby]
13445 *) Quote CC='$(CC)' to improve recurse make calls. [Martin Kraemer]
13447 *) Avoid B_ERROR redeclaration on sysvr4 systems. [Martin Kraemer]
13449 Changes with Apache 1.2.5
13451 *) SECURITY: Fix a possible buffer overflow in logresolve. This is
13452 only an issue on systems without a MAXDNAME define or where
13453 the resolver returns domain names longer than MAXDNAME. [Marc Slemko]
13455 *) Fix an improper length in an ap_snprintf call in proxy_date_canon().
13458 *) Fix core dump in the ftp proxy when reading incorrectly formatted
13459 directory listings. [Marc Slemko]
13461 *) SECURITY: Fix possible minor buffer overflow in the proxy cache.
13464 *) SECURITY: Eliminate possible buffer overflow in cfg_getline, which
13465 is used to read various types of files such as htaccess and
13466 htpasswd files. [Marc Slemko]
13468 *) SECURITY: Ensure that the buffer returned by ht_time is always
13469 properly null terminated. [Marc Slemko]
13471 *) SECURITY: General mod_include cleanup, including fixing several
13472 possible buffer overflows and a possible infinite loop. This cleanup
13473 was done against 1.3 code and then backported to 1.2, the result
13474 is a large difference (due to indentation cleanup in 1.3 code).
13475 Users interested in seeing a smaller set of relevant differences
13476 should consider comparing against src/modules/standard/mod_include.c
13477 from the 1.3b3 release. Non-indentation changes to mod_include
13478 between 1.2 and 1.3 were minimal. [Dean Gaudet, Marc Slemko]
13480 *) SECURITY: Numerous changes to mod_imap in a general cleanup
13481 including fixing a possible buffer overflow. This cleanup also
13482 was done with 1.3 code as a basis, see the previous note
13483 about mod_include. [Dean Gaudet]
13485 *) SECURITY: If a htaccess file can not be read due to bad
13486 permissions, deny access to the directory with a HTTP_FORBIDDEN.
13487 The previous behavior was to ignore the htaccess file if it could not
13488 be read. This change may make some setups with unreadable
13489 htaccess files stop working. PR#817 [Marc Slemko]
13491 *) SECURITY: no2slash() was O(n^2) in the length of the input.
13492 Make it O(n). This inefficiency could be used to mount a denial
13493 of service attack against the Apache server. Thanks to
13494 Michal Zalewski <lcamtuf boss.staszic.waw.pl> for reporting
13495 this. [Dean Gaudet]
13497 *) mod_include used uninitialized data for some uses of && and ||.
13498 [Brian Slesinsky <bslesins wired.com>] PR#1139
13500 *) mod_imap should decline all non-GET methods.
13501 [Jay Bloodworth <jay pathways.sde.state.sc.us>]
13503 *) suexec.c wouldn't build without -DLOG_EXEC. [Jason A. Dour]
13505 *) mod_userdir was modifying r->finfo in cases where it wasn't setting
13506 r->filename. Since those two are meant to be in sync with each other
13507 this is a bug. ["Paul B. Henson" <henson intranet.csupomona.edu>]
13509 *) mod_include did not properly handle all possible redirects from sub-
13510 requests. [Ken Coar]
13512 *) Inetd mode (which is buggy) uses timeouts without having setup the
13513 jmpbuffer. [Dean Gaudet] PR#1064
13515 *) Work around problem under Linux where a child will start looping
13516 reporting a select error over and over.
13517 [Rick Franchuk <rickf transpect.net>] PR#1107
13519 Changes with Apache 1.2.4
13521 *) The ProxyRemote change in 1.2.3 introduced a bug resulting in the proxy
13522 always making requests with the full-URI instead of just the URI path.
13523 [Marc Slemko, Roy Fielding]
13525 *) Add -lm for AIX versions >= 4.2 to allow Apache to link properly
13526 on this platform. [Marc Slemko]
13528 Changes with Apache 1.2.3
13530 *) The request to a remote proxy was mangled if it was generated as the
13531 result of a ProxyPass directive. URL schemes other than http:// were not
13532 supported when ProxyRemote was used. PR#260, PR#656, PR#699, PR#713,
13533 PR#812 [Lars Eilebrecht]
13535 *) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
13536 information for case where proxy module is not available. [Marc Slemko]
13538 *) Force proxy to always respond as HTTP/1.0, which it was failing to
13539 do for errors and cached responses. [Roy Fielding]
13541 *) PORT: Improved support for ConvexOS 11. [Jeff Venters]
13543 Changes with Apache 1.2.2 [not released]
13545 *) Fixed another long-standing bug in sub_req_lookup_file where it would
13546 happily skip past access checks on subdirectories looked up with relative
13547 paths. (It's used by mod_dir, mod_negotiation, and mod_include.)
13550 *) Add lockfile name to error message printed out when
13551 USE_FLOCK_SERIALIZED_ACCEPT is defined.
13554 *) Enhanced the chunking and error handling inside the buffer functions.
13555 [Dean Gaudet, Roy Fielding]
13557 *) When merging the main server's <Directory> and <Location> sections into
13558 a vhost, put the main server's first and the vhost's second. Otherwise
13559 the vhost can't override the main server. [Dean Gaudet] PR#717
13561 *) The <Directory> code would merge and re-merge the same section after
13562 a match was found, possibly causing problems with some modules.
13565 *) Fixed an infinite loop in mod_imap for references above the server root.
13566 [Dean Gaudet] PR#748
13568 *) mod_include cleanup showed that handle_else was being used to handle
13569 endif. It didn't cause problems, but it was cleaned up too.
13572 *) Last official synchronization of mod_rewrite with author version (because
13573 mod_rewrite is now directly developed by the author at the Apache Group):
13574 o added diff between mod_rewrite 3.0.6+ and 3.0.9
13575 minus WIN32/NT stuff, but plus copyright removement.
13577 - workaround for detecting infinite rewriting loops
13578 - fixed setting of env vars when "-" is used as subst string
13579 - fixed forced response code on redirects (PR#777)
13580 - fixed cases where r->args is ""
13581 - kludge to disable locking on pipes under braindead SunOS
13582 - fix for rewritelog in cases where remote hostname is unknown
13583 - fixed totally damaged request_rec walk-back loop
13584 o remove static from local data and add static to global ones.
13585 o replaced ugly proxy finding stuff by simple
13586 find_linked_module("mod_proxy") call.
13587 o added missing negation char on rewritelog()
13588 o fixed a few comment typos

13591 *) Anonymous_LogEmail was logging on each subrequest.
13592 [Dean Gaudet] PR#421, PR#868
13594 *) "force-response-1.0" now only applies to requests which are HTTP/1.0 to
13595 begin with. "nokeepalive" now works for HTTP/1.1 clients. Added
13596 "downgrade-1.0" which causes Apache to pretend it received a 1.0.
13597 Additionally mod_browser now triggers during translate_name to workaround
13598 a deficiency in the header_parse phase.

13616 under Solaris 2.x (up through 2.5.1). It has been fixed.
13617 [Dean Gaudet] PR#832
13619 *) API: In HTTP/1.1, whether or not a request message contains a body
13620 is independent of the request method and based solely on the presence
13621 of a Content-Length or Transfer-Encoding. Therefore, our default
13622 handlers need to be prepared to read a body even if they don't know
13623 what to do with it; otherwise, the body would be mistaken for the
13624 next request on a persistent connection. discard_request_body()
13625 has been added to take care of that. [Roy Fielding] PR#378
13627 *) API: Symbol APACHE_RELEASE provides a numeric form of the Apache
13628 release version number, such that it always increases along the
13629 same lines as our source code branching. [Roy Fielding]
13631 *) Minor oversight on multiple variants fixed. [Paul Sutton] PR#94
13633 Changes with Apache 1.2.1
13635 *) SECURITY: Don't serve file system objects unless they are plain files,
13636 symlinks, or directories. This prevents local users from using pipes
13637 or named sockets to invoke programs for an extremely crude form of

13641 could contain "../" allowing a local user to "publish" any file on
13642 the system. No slashes are allowed now. [Dean Gaudet]
13644 *) SECURITY: It was possible to violate the symlink Options using mod_dir
13645 (headers, readmes, titles), mod_negotiation (type maps), or
13646 mod_cern_meta (meta files). [Dean Gaudet]
13648 *) SECURITY: Apache will refuse to run as "User root" unless
13649 BIG_SECURITY_HOLE is defined at compile time. [Dean Gaudet]
13651 *) CONFIG: If a symlink pointed to a directory then it would be disallowed
13652 if it contained a .htaccess disallowing symlinks. This is contrary
13653 to the rule that symlink permissions are tested with the symlink
13654 options of the parent directory. [Dean Gaudet] PR#353
13656 *) CONFIG: The LockFile directive can be used to place the serializing
13657 lockfile in any location. It previously defaulted to /usr/tmp/htlock.
13658 [Somehow it took four of us: Randy Terbush, Jim Jagielski, Dean Gaudet,
13661 *) Request processing now retains state of whether or not the request
13662 body has been read, so that internal redirects and subrequests will
13663 not try to read it twice (and block). [Roy Fielding]
13665 *) Add a placeholder in modules/Makefile to avoid errors with certain
13666 makes. [Marc Slemko]
13668 *) QUERY_STRING was unescaped in mod_include, it shouldn't be.

13674 *) Attempt to work around problems with third party libraries that do not
13675 handle high numbered descriptors (examples include bind, and
13676 solaris libc). On all systems apache attempts to keep all permanent
13677 descriptors above 15 (called the low slack line). Solaris users
13678 can also benefit from adding -DHIGH_SLACK_LINE=256 to EXTRA_CFLAGS
13679 which keeps all non-FILE * descriptors above 255. On all systems
13680 this should make supporting large numbers of vhosts with many open
13681 log files more feasible. If this causes trouble please report it,
13682 you can disable this workaround by adding -DNO_SLACK to EXTRA_CFLAGS.
13683 [Dean Gaudet] various PRs
13685 *) Related to the last entry, network sockets are now opened before
13686 log files are opened. The only known case where this can cause
13687 problems is under Solaris with many virtualhosts and many Listen
13688 directives. But using -DHIGH_SLACK_LINE=256 described above will
13689 work around this problem. [Dean Gaudet]
13691 *) USE_FLOCK_SERIALIZED_ACCEPT is now default for FreeBSD, A/UX, and

13696 *) Update mod_rewrite from 3.0.5 to 3.0.6. New ruleflag
13697 QSA=query_string_append. Also fixed a nasty bug in per-dir context:
13698 when a URL http://... was used in conjunction with a special

13744 reading from one buffer and writing to another, at least until it has
13745 a custom timeout handler. [Roy Fielding and Petr Lampa]

13790 original request-line. [Roy Fielding]
13792 *) Test for error conditions before creating output header fields, since
13793 we don't want the error message to include those fields. Likewise,
13794 reset the content_language(s) and content_encoding of the response
13795 before generating or redirecting to an error message, since the new
13796 message will have its own Content-* definitions. [Dean Gaudet]

13799 and 304 responses) and err_headers_out (headers sent with all responses).
13800 Avoid the overhead of copying tables if err_headers_out is empty
13801 (the usual case). [Roy Fielding]
13803 *) Fixed a couple places where a check for the default Content-Type was
13804 not properly checking both the value configured by the DefaultType

13816 *) The method for determining PATH_INFO has been restored to the pre-1.2b
13817 (and NCSA httpd) definition wherein it was the extra path info beyond
13818 the CGI script filename. The environment variable FILEPATH_INFO has
13819 been removed, and instead we supply the original REQUEST_URI to any
13820 script that wants to be Apache-specific and needs the real URI path.
13821 This solves a problem with existing scripts that use extra path info
13822 in the ScriptAlias directive to pass options to the CGI script.
13825 *) The _default_ change in 1.2b10 will change the behaviour on configs
13826 that use multiple Listen statements for listening on multiple ports.
13827 But that change is necessary to make _default_ consistent with other
13828 forms of <VirtualHost>. It requires such configs to be modified

13866 *) Rearrange Configuration.tmpl so that mod_rewrite has higher priority
13867 than mod_alias, and mod_alias has higher priority than mod_proxy;
13868 rearranged other modules to enhance understanding of their purpose
13869 and relative order (and maybe even reduce some overhead).
13870 [Roy Fielding and Sameer Parekh]
13872 *) Fix graceful restart. Eliminate many signal-related race
13873 conditions in both forms of restart, and in SIGTERM. See
13874 htdocs/manual/stopping.html for details on stopping and
13875 restarting the parent. [Dean Gaudet]
13877 *) Fix memory leaks in mod_rewrite, mod_browser, mod_include. Tune
13878 memory allocator to avoid a behaviour that required extra blocks to
13879 be allocated. [Dean Gaudet]
13881 *) Allow suexec to access files relative to current directory but not
13882 above. (Excluding leading / or any .. directory.) [Ken Coar]
13885 *) Fix suexec segfault when group doesn't exist. [Gregory Neil Shapiro]
13886 PR#367, 368, 354, 453
13888 *) Fix the above fix: if suexec is enabled, avoid destroying r->url
13889 while obtaining the /~user and save the username in a separate data
13890 area so that it won't be overwritten by the call to getgrgid(), and
13891 fix some misuse of the pool string allocation functions. Also fixes
13892 a general problem with parsing URL query info into args for CGI scripts.
13893 [Roy Fielding] PR#339, 367, 354, 453
13895 *) Fix IRIX warning about bzero undefined. [Marc Slemko]
13897 *) Fix problem with <Directory proxy:...>. [Martin Kraemer] PR#271
13899 *) Corrected spelling of "authoritative". AuthDBAuthoratative became
13900 AuthDBAuthoritative. [Marc Slemko] PR#420
13902 *) MaxClients should be at least 1. [Lars Eilebrecht] PR#375
13904 *) The default handler now logs invalid methods or URIs (i.e. PUT on an
13905 object that can't be PUT, or FOOBAR for some method FOOBAR that
13906 apache doesn't know about at all). Log 404s that occur in mod_include.
13907 [Paul Sutton, John Van Essen]
13909 *) If a soft timeout (or lingerout) occurs while trying to flush a
13910 buffer or write inside buff.c or fread'ing from a CGI's output,
13911 then the timeout would be ignored. [Roy Fielding] PR#373
13913 *) Work around a bug in Netscape Navigator versions 2.x, 3.x and 4.0b2's
13914 parsing of headers. If the terminating empty-line CRLF occurs starting
13915 at the 256th or 257th byte of output, then Navigator will think a normal
13916 image is invalid. We are guessing that this is because their initial
13917 read of a new request uses a 256 byte buffer. We check the bytes written
13918 so far and, if we are about to tickle the bug, we instead insert a
13919 padding header of eminent bogosity. [Roy Fielding and Dean Gaudet] PR#232
13921 *) Fixed SIGSEGV problem when a DirectoryIndex file is also the source
13922 of an external redirection. [Roy Fielding and Paul Sutton]
13924 *) Configure would create a broken Makefile if the configuration file
13925 contained a commented-out Rule. [Roy Fielding]
13927 *) Promote per_dir_config and subprocess_env from the subrequest to the
13928 main request in mod_negotiation. In particular this fixes a bug
13929 where <Files> sections wouldn't properly apply to negotiated content.
13932 *) Fix a potential deadlock in mod_cgi script_err handling.
13933 [Ralf S. Engelschall]
13935 *) rotatelogs zero-pads the logfile names to improve alphabetic sorting.
13936 [Mitchell Blank Jr]
13938 *) Updated mod_rewrite to 3.0.4: Fixes HTTP redirects from within
13939 .htaccess files because the RewriteBase was not replaced correctly.
13940 Updated mod_rewrite to 3.0.5: Fixes problem with rewriting inside
13941 <Directory> sections missing a trailing /. [Ralf S. Engelschall]
13943 *) Clean up Linux settings in conf.h by detecting 2.x versus 1.x. For
13944 1.x the settings are those of pre-1.2b8. For 2.x we include
13945 USE_SHMGET_SCOREBOARD (scoreboard in shared memory rather than file) and
13946 HAVE_SYS_RESOURCE_H (enable the RLimit commands).
13947 [Dean Gaudet] PR#336, PR#340
13949 *) Redirect did not preserve ?query_strings when present in the client's
13950 request. [Dean Gaudet]
13952 *) Configure was finding non-modules on EXTRA_LIBS. [Frank Cringle] PR#380
13954 *) Use /bin/sh5 on ULTRIX. [P. Alejandro Lopez-Valencia] PR#369
13956 *) Add UnixWare compile/install instructions. [Chuck Murcko]
13958 *) Add mod_example (illustration of API techniques). [Ken Coar]
13960 *) Add macro for memmove to conf.h for SUNOS4. [Marc Slemko]
13962 *) Improve handling of directories when filenames have spaces in them.
13965 *) For hosts with multiple IP addresses, try all additional addresses if
13966 necessary to get a connect. Fail only if hostent address list is
13967 exhausted. [Chuck Murcko]
13969 *) More signed/unsigned port fixes. [Dean Gaudet]
13971 *) HARD_SERVER_LIMIT can be defined in the Configuration file now.
13974 Changes with Apache 1.2b8
13976 *) suexec.c doesn't close the log file, allowing CGIs to continue writing
13977 to it. [Marc Slemko]
13979 *) The addition of <Location> and <File> directives made the
13980 sub_req_lookup_simple() function bogus, so we now handle
13981 the special cases directly. [Dean Gaudet]
13983 *) We now try to log where the server is dumping core when a fatal
13984 signal is received. [Ken Coar]
13986 *) Improved lingering_close by adding a special timeout, removing the
13987 spurious log messages, removing the nonblocking settings (they
13988 are not needed with the better timeout), and adding commentary
13989 about the NO_LINGCLOSE and USE_SO_LINGER issues. NO_LINGCLOSE is
13990 now the default for SunOS4, UnixWare, NeXT, and IRIX. [Roy Fielding]
13992 *) Send error messages about setsockopt failures to the server error
13993 log instead of stderr. [Roy Fielding]
13995 *) Fix loopholes in proxy cache expiry vis a vis alarms. [Brian Moore]
13997 *) Stopgap solution for CGI 3-second delay with server-side includes: if
13998 processing a subrequest, allocate memory from r->main->pool instead
13999 of r->pool so that we can avoid waiting for free_proc_chain to cleanup
14000 in the middle of an SSI request. [Dean Gaudet] PR #122
14002 *) Fixed status of response when POST is received for a nonexistent URL
14003 (was sending 405, now 404) and when any method is sent with a
14004 full-URI that doesn't match the server and the server is not acting
14005 as a proxy (was sending 501, now 403). [Roy Fielding]
14007 *) Host port changed to unsigned short. [Ken Coar] PR #276
14009 *) Fix typo in command definition of AuthAuthoritative. [Ken Coar] PR #246
14011 *) Defined USE_SHMGET_SCOREBOARD for shared memory on Linux. [Dean Gaudet]
14013 *) Report extra info from errno with many errors that cause httpd to exit.
14014 spawn_child, popenf, and pclosef now have valid errno returns in the
14015 event of an error. Correct problems where errno was stomped on
14016 before being reported. [Dean Gaudet]
14018 *) In the proxy, if the cache filesystem was full, garbage_coll() was
14019 never called, and thus the filesystem would remain full indefinitely.
14020 We now also remove incomplete cache files left if the origin server
14021 didn't send a Content-Length header and either the client has aborted
14022 transfer or bwrite() to client has failed. [Petr Lampa]
14024 *) Fixed the handling of module and script-added header fields.
14025 Improved the interface for sending header fields and reduced
14026 the duplication of code between sending okay responses and errors.
14027 We now always send both headers_out and err_headers_out, and
14028 ensure that the server-reserved fields are not being overridden,
14029 while not overriding those that are not reserved. [Roy Fielding]
14031 *) Moved transparent content negotiation fields to err_headers_out
14032 to reflect above changes. [Petr Lampa]
14034 *) Fixed the determination of whether or not we should make the
14035 connection persistent for all of the cases where some other part
14036 of the server has already indicated that we should not. Also
14037 improved the ordering of the test so that chunked encoding will
14038 be set whenever it is desired instead of only when KeepAlive
14039 is enabled. Added persistent connection capability for most error
14040 responses (those that do not indicate a bad input stream) when
14041 accessed by an HTTP/1.1 client. [Roy Fielding]
14043 *) Added missing timeouts for sending header fields, error responses,
14044 and the last chunk of chunked encoding, each of which could have
14045 resulted in a process being stuck in write forever. Using soft_timeout
14046 requires that the sender check for an aborted connection rather than
14047 continuing after an EINTR. Timeouts that used to be initiated before
14048 send_http_header (and never killed) are now initiated only within or
14049 around the routines that actually do the sending, and not allowed to
14050 propagate above the caller. [Roy Fielding]
14052 *) mod_auth_anon required an @ or a . in the email address, not both.
14055 *) per_dir_defaults weren't set correctly until directory_walk for
14056 name-based vhosts. This fixes an obscure bug with the wrong config
14057 info being used for vhosts that share the same ip as the server.
14060 *) Improved generation of modules/Makefile to be more generic for
14061 new module directories. [Ken Coar, Chuck Murcko, Roy Fielding]
14063 *) Generate makefile dependency for Configuration based on the actual
14064 name given when running the Configure process. [Dean Gaudet]
14066 *) Fixed problem with vhost error log not being set prior to
14067 initializing virtual hosts. [Dean Gaudet]
14069 *) Fixed infinite loop when a trailing slash is included after a type map
14070 file URL (extra path info). [Petr Lampa]
14072 *) Fixed server status updating of per-connection counters. [Roy Fielding]
14074 *) Add documentation for DNS issues (reliability and security), and try
14075 to explain the virtual host matching process. [Dean Gaudet]
14077 *) Try to continue gracefully by disabling the vhost if a DNS lookup
14078 fails while parsing the configuration file. [Dean Gaudet]
14080 *) Improved calls to setsockopt. [Roy Fielding]
14082 *) Negotiation changes: Don't output empty content-type in variant list;
14083 Output charset in variant list; Return sooner from handle_multi() if
14084 no variants found; Add handling of '*' wildcard in Accept-Charset.
14085 [Petr Lampa and Paul Sutton]
14087 *) Fixed overlaying of request/sub-request notes and headers in
14088 mod_negotiation. [Dean Gaudet]
14090 *) If two variants' charset quality are equal and one is the default
14091 charset (iso-8859-1), then prefer the variant that was specifically
14092 listed in Accept-Charset instead of the default. [Petr Lampa]
14094 *) Memory allocation problem in push_array() -- it would corrupt memory
14095 when nalloc==0. [Kai Risku <krisku tf.hut.fi> and Roy Fielding]
14097 *) invoke_handler() doesn't handle mime arguments in content-type
14098 [Petr Lampa] PR#160
14100 *) Reduced IdentityCheck timeout to 30 seconds, as per RFC 1413 minimum.
14103 *) Fixed problem with ErrorDocument not working for virtual hosts
14104 due to one of the performance changes in 1.2b7. [Dean Gaudet]
14106 *) Log an error message if we get a request header that is too long,
14107 since it may indicate a buffer overflow attack. [Marc Slemko]
14109 *) Made is_url() allow "[-.+a-zA-Z0-9]+:" as a valid scheme and
14110 not reject URLs without a double-slash, as per RFC2068 section 3.2.
14111 [Ken Coar] PR #146, #187
14113 *) Added table entry placeholder for new header_parser callback
14114 in all of the distributed modules. [Ken Coar] PR #191
14116 *) Allow for cgi files without the .EXE extension on them under OS/2.
14117 [Garey Smiley] PR #59
14119 *) Fixed error message when resource is not found and URL contains
14120 path info. [Petr Lampa and Dean Gaudet] PR #40
14122 *) Fixed user and server confusion over what should be a virtual host
14123 and what is the main server, resulting in access to something
14124 other than the name defined in the virtualhost directive (but
14125 with the same IP address) failing. [Dean Gaudet]
14127 *) Updated mod_rewrite to version 3.0.2, which: fixes compile error on
14128 AIX; improves the redirection stuff to enable the users to generally
14129 redirect to http, https, gopher and ftp; added TIME variable for
14130 RewriteCond which expands to YYYYMMDDHHMMSS strings and added the
14131 special patterns >STRING, <STRING and =STRING to RewriteCond, which
14132 can be used in conjunction with %{TIME} or other variables to create
14133 time-dependent rewriting rules. [Ralf S. Engelschall]
14135 *) bpushfd() no longer notes cleanups for the file descriptors it is handed.
14136 Module authors may need to adjust their code for proper cleanup to take
14137 place (that is, call note_cleanups_for_fd()). This change fixes problems
14138 with file descriptors being erroneously closed when the proxy module was
14139 in use. [Ben Laurie]
14141 *) Fix bug in suexec reintroduced by changes in 1.2b7 which allows
14142 initgroups() to hose the group information needed for later
14143 comparisons. [Randy Terbush]
14145 *) Remove unnecessary call to va_end() in create_argv() which
14146 caused a SEGV on some systems.
14148 *) Use proper MAXHOSTNAMELEN symbol for limiting length of server name.
14151 *) Clear memory allocated for listeners. [Randy Terbush]
14153 *) Improved handling of IP address as a virtualhost address and
14154 introduced "_default_" as a synonym for the default vhost config.
14155 [Dean Gaudet] PR #212
14157 Changes with Apache 1.2b7
14159 *) Port to UXP/DS(V20) [Toshiaki Nomura <nom yk.fujitsu.co.jp>]
14161 *) unset Content-Length if chunked (RFC-2068) [Petr Lampa]
14163 *) mod_negotiation fixes [Petr Lampa] PR#157, PR#158, PR#159
14164 - replace protocol response numbers with symbols
14165 - save variant-list into main request notes
14166 - free allocated memory from subrequests
14167 - merge notes, headers_out and err_headers_out
14169 *) changed status check mask in proxy_http.c from "HTTP/#.# ### *" to
14170 "HTTP/#.# ###*" to be more lenient about what we accept.
14173 *) more proxy FTP bug fixes:
14174 - Changed send_dir() to remove user/passwd from displayed URL.
14175 - Changed login error messages to be more descriptive.
14176 - remove setting of SO_DEBUG socket option
14177 - Make ftp_getrc() more lenient about multiline responses,
14178 specifically, 230 responses which don't have continuation 230-
14179 on each line). These seem to be all NT FTP servers, and while
14180 perhaps questionable, they appear to be legal by RFC 959.
14181 - Add missing kill_timeout() after transfer to user completes.
14184 *) Fixed problem where a busy server could hang when restarting
14185 after being sent a SIGHUP due to child processes not exiting.
14188 *) Modify mod_include escaping so a '\' only signifies an escaped
14189 character if the next character is one that needs
14190 escaping. [Ben Laurie]
14192 *) Eliminated possible infinite loop in mod_imap when relative URLs are
14193 used with a 'base' directive that does not have a '/' in it.
14194 [Marc Slemko, reported by Onno Witvliet <onno tc.hsa.nl>]
14196 *) Reduced the default timeout from 1200 seconds to 300, and the
14197 one in the sample configfile from 400 to 300. [Marc Slemko]
14199 *) Stop vbprintf from crashing if given a NULL string pointer;
14200 print (null) instead. [Ken Coar]
14202 *) Don't disable Nagle algorithm if system doesn't have TCP_NODELAY.
14203 [Marc Slemko and Roy Fielding]
14205 *) Fixed problem with mod_cgi-generated internal redirects trying to
14206 read the request message-body twice. [Archie Cobbs and Roy Fielding]
14208 *) Reduced timeout on lingering close, removed possibility of a blocked
14209 read causing the child to hang, and stopped logging of errors if
14210 the socket is not connected (reset by client). [Roy Fielding]
14212 *) Rearranged main child loop to remove duplication of code in
14213 select/accept and keep-alive requests, fixed several bugs regarding
14214 checking scoreboard_image for exit indication and failure to
14215 account for all success conditions and trap all error conditions,
14216 prevented multiple flushes before closing the socket; close the entire
14217 socket buffer instead of just one descriptor, prevent logging of
14218 EPROTO and ECONNABORTED on platforms where supported, and generally
14219 improved readability. [Roy Fielding]
14221 *) Extensive performance improvements. Cleaned up inefficient use of
14222 auto initializers, multiple is_matchexp calls on a static string,
14223 and excessive merging of response_code_strings. [Dean Gaudet]
14225 *) Added double-buffering to mod_include to improve performance on
14226 server-side includes. [Marc Slemko]
14228 *) Several fixes for suexec wrapper. [Randy Terbush]
14229 - Make wrapper work for files on NFS filesystem.
14230 - Fix portability problem of MAXPATHLEN.
14231 - Fix array overrun problem in clean_env().
14232 - Fix allocation of PATH environment variable
14234 *) Removed extraneous blank line is description of mod_status chars.
14237 *) Logging of errors from the call_exec routine simply went nowhere,
14238 since the logfile fd has been closed, so now we send them to stderr.
14239 [Harald T. Alvestrand]
14241 *) Fixed core dump when DocumentRoot is a CGI.
14242 [Ben Laurie, reported by <geddis tesserae.com>]
14244 *) Fixed potential file descriptor leak in mod_asis; updated it and
14245 http_core to use pfopen/pfclose instead of fopen/fclose.
14246 [Randy Terbush and Roy Fielding]
14248 *) Fixed handling of unsigned ints in ap_snprintf() on some chips such
14249 as the DEC Alpha which is 64-bit but uses 32-bit ints.
14250 [Dean Gaudet and Ken Coar]
14252 *) Return a 302 response code to the client when sending a redirect
14253 due to a missing trailing '/' on a directory instead of a 301; now
14254 it is cacheable. [Markus Gyger]
14256 *) Fix condition where, if a bad directive occurs in .htaccess, and
14257 sub_request() goes first to this directory, then log_reason() will
14258 SIGSEGV because it doesn't have initialized r->per_dir_config.
14259 [PR#162 from Petr Lampa, fix by Marc Slemko and Dean Gaudet]
14261 *) Fix handling of lang_index in is_variant_better(). This was
14262 causing problems which resulted in the server sending the
14263 wrong language document in some cases. [Petr Lampa]
14265 *) Remove free() from clean_env() in suexec wrapper. This was nuking
14266 the clean environment on some systems.
14268 *) Tweak byteserving code (e.g. serving PDF files) to work around
14269 bugs in Netscape Navigator and Microsoft Internet Explorer.
14270 Emit Content-Length header when sending multipart/byteranges.
14273 *) Port to HI-UX/WE2. [Nick Maclaren]
14275 *) Port to HP MPE operating system for HP 3000 machines
14276 [Mark Bixby <markb cccd.edu>]
14278 *) Fixed bug which caused a segmentation fault if only one argument
14279 given to RLimit* directives. [Ed Korthof]
14281 *) Continue persistent connection after 204 or 304 response. [Dean Gaudet]
14283 *) Improved buffered output to the client by delaying the flush decision
14284 until the BUFF code is actually about to read the next request.
14285 This fixes a problem introduced in 1.2b5 with clients that send
14286 an extra CRLF after a POST request. Also improved chunked output
14287 performance by combining writes using writev() and removing as
14288 many bflush() calls as possible. NOTE: Platforms without writev()
14289 must add -DNO_WRITEV to the compiler CFLAGS, either in Configuration
14290 or Configure, unless we have already done so. [Dean Gaudet]
14292 *) Fixed mod_rewrite bug which truncated the rewritten URL [Marc Slemko]
14294 *) Fixed mod_info output corruption bug introduced by buffer overflow
14295 fixes. [Dean Gaudet]
14297 *) Fixed http_protocol to correctly output all HTTP/1.1 headers, including
14298 for the special case of a 304 response. [Paul Sutton]
14300 *) Improved handling of TRACE method by bypassing normal method handling
14301 and header parsing routines; fixed Allow response to always allow TRACE.
14304 *) Fixed compiler warnings in the regex library. [Dean Gaudet]
14306 *) Cleaned-up some of the generated HTML. [Ken Coar]
14308 Changes with Apache 1.2b6
14310 *) Allow whitespace in imagemap mapfile coordinates. [Marc Slemko]
14312 *) Fix typo introduced in fix for potential infinite loop around
14313 accept() in child_main(). This change caused the rev to 1.2b6.
14314 1.2b5 was never a public beta.
14316 Changes with Apache 1.2b5
14318 *) Change KeepAlive semantics (On|Off instead of a number), add
14319 MaxKeepAliveRequests directive. [Alexei Kosut]
14321 *) Various NeXT compilation patches, as well as a change in
14322 regex/regcomp.c since that file also used a NEXT define.
14325 *) Allow * to terminate the end of a directory match in mod_dir.
14326 Allows /~* to match for both /~joe and /~joe/. [David Bronder]
14328 *) Don't call can_exec() if suexec_enabled. Calling this requires
14329 scripts executed by the suexec wrapper to be world executable, which
14330 defeats one of the advantages of running the wrapper. [Randy Terbush]
14332 *) Portability Fix: IRIX complained with 'make clean' about *pure* (removed)
14335 *) Migration from sprintf() to snprintf() to avoid buffer
14336 overflows. [Marc Slemko]
14338 *) Provide portable snprintf() implementation (ap_snprintf)
14339 as well as *cvt family. [Jim Jagielski]
14341 *) Portability Fix: NeXT lacks unistd.h so we wrap it's inclusion
14344 *) Remove mod_fastcgi.c from the distribution. This module appears
14345 to be maintained more through the Open Market channels and should
14346 continue to be easily available at http://www.fastcgi.com/
14348 *) Fixed bug in modules/Makefile that wouldn't allow building in more
14349 than one subdirectory (or cleaning, either). [Jeremy Laidman]
14351 *) mod_info assumed that the config files were relative to ServerRoot.
14354 *) CGI scripts called as an error document resulting from failed
14355 CGI execution would hang waiting for POST'ed data. [Rob Hartill]
14357 *) Log reason when mod_dir returns access HTTP_FORBIDDEN
14360 *) Properly check errno to prevent display of a directory index
14361 when server receives a long enough URL to confuse stat().
14364 *) Several security enhancements to suexec wrapper. It is _highly_
14365 recommended that previously installed versions of the wrapper
14366 be replaced with this version. [Randy Terbush, Jason Dour]
14368 - ~user execution now properly restricted to ~user's home
14369 directory and below.
14370 - execution restricted to UID/GID > 100
14371 - restrict passed environment to known variables
14372 - call setgid() before initgroups() (portability fix)
14373 - remove use of setenv() (portability fix)
14375 *) Add HTTP/1.0 response forcing. [Ben Laurie]
14377 *) Add access control via environment variables. [Ben Laurie]
14379 *) Add rflush() function. [Alexei Kosut]
14381 *) remove duplicate pcalloc() call in new_connection().
14383 *) Fix incorrect comparison which could allow number of children =
14384 MaxClients + 1 if less than HARD_SERVER_LIMIT. Also fix potential
14385 problem if StartServers > HARD_SERVER_LIMIT. [Ed Korthof]
14387 *) Updated support for OSes (MachTen, ULTRIX, Paragon, ISC, OpenBSD
14388 AIX PS/2, CONVEXOS. [Jim Jagielski]
14390 *) Replace instances of inet_ntoa() with inet_addr() for ProxyBlock.
14391 It's more portable. [Martin Kraemer]
14393 *) Replace references to make in Makefile.tmpl with $(MAKE).
14396 *) Add ProxyBlock directive w/IP address caching. Add IP address
14397 caching to NoCache directive as well. ProxyBlock works with all
14398 handlers; NoCache now also works with FTP for anonymous logins.
14399 Still more code cleanup. [Chuck Murcko]
14401 *) Add "header parse" API hook [Ben Laurie]
14403 *) Fix byte ordering problems for REMOTE_PORT [Chuck Murcko]
14405 *) suEXEC wrapper was freeing memory that had not been malloc'ed.
14407 *) Correctly allow access and auth directives in <Files> sections in
14408 server config files. [Alexei Kosut]
14410 *) Fix bug with ServerPath that could cause certain files to be not
14411 found by the server. [Alexei Kosut]
14413 *) Fix handling of ErrorDocument so that it doesn't remove a trailing
14414 double-quote from text and so that it properly checks for unsupported
14415 status codes using the new index_of_response interface. [Roy Fielding]
14417 *) Multiple fixes to the lingering_close code in order to avoid being
14418 interrupted by a stray timeout, to avoid lingering on a connection
14419 that has already been aborted or never really existed, to ensure that
14420 we stop lingering as soon as any error condition is received, and to
14421 prevent being stuck indefinitely if the read blocks. Also improves
14422 reporting of error conditions. [Marc Slemko and Roy Fielding]
14424 *) Fixed initialization of parameter structure for sigaction.
14425 [<mgyger itr.ch>, Adrian Filipi-Martin]
14427 *) Fixed reinitializing the parameters before each call to accept and
14428 select, and removed potential for infinite loop in accept.
14429 [Roy Fielding, after useful PR from <adrian virginia.edu>]
14431 *) Fixed condition where, if a child fails to fork, the scoreboard would
14432 continue to say SERVER_STARTING forever. Eventually, the main process
14433 would refuse to start new children because count_idle_servers() will
14434 count those SERVER_STARTING entries and will always report that there
14435 are enough idle servers. [Phillip Vandry]
14437 *) Fixed bug in bcwrite regarding failure to account for partial writes.
14438 Avoided calling bflush() when the client is pipelining requests.
14439 Removed unnecessary flushes from http_protocol. [Dean Gaudet]
14441 *) Added description of "." mode in server-status [Jim Jagielski]
14443 Changes with Apache 1.2b4
14445 *) Fix possible race condition in accept_mutex_init() that
14446 could leave a small security hole open allowing files to be
14447 overwritten in cases where the server UID has write permissions.
14450 *) Fix awk compatibilty problem in Configure. [Jim Jagielski]
14452 *) Fix portablity problem in util_script where ARG_MAX may not be
14453 defined for some systems.
14455 *) Add changes to allow compilation on Machten 4.0.3 for PowerPC.
14458 *) OS/2 changes to support an MMAP style scoreboard file and UNIX
14459 style magic #! token for better script portability. [Garey Smiley]
14461 *) Fix bug in suexec wrapper introduced in b3 that would cause failed
14462 execution for ~userdir CGI. [Jason Dour]
14464 *) Fix initgroups() business in suexec wrapper. [Jason Dour]
14466 *) Fix month off by one in suexec wrapper logging.
14468 Changes with Apache 1.2b3:
14470 *) Fix error in mod_cgi which could cause resources not to be properly
14471 freed, or worse. [Dean Gaudet]
14473 *) Fix find_string() NULL pointer dereference. [Howard Fear]
14475 *) Add set_flag_slot() at the request of Dirk and others.
14478 *) Sync mod_rewrite with patch level 10. [Ralf Engelschall]
14480 *) Add changes to improve the error message given for invalid
14481 ServerName parameters. [Dirk vanGulik]
14483 *) Add "Authoritative" directive for Auth modules that don't
14484 currently have it. This gives admin control to assign authoritative
14485 control to an authentication scheme and allow "fall through" for
14486 those authentication modules that aren't "Authoritative" thereby
14487 allowing multiple authentication mechanisms to be chained.
14490 *) Remove requirement for ResourceConfig/AccessConfig if not using
14491 the three config file layout. [Randy Terbush]
14493 *) Add PASV mode to mod_proxy FTP handler. [Chuck Murcko]
14495 *) Changes to suexec wrapper to fix the following problems:
14496 1. symlinked homedirs will kill ~userdirs.
14497 2. initgroups() on Linux 2.0.x clobbers gr->grid.
14498 3. CGI command lines paramters problems
14499 4. pw-pwdir for "docroot check" still the httpd user's pw record.
14500 [Randy Terbush, Jason Dour]
14502 *) Change create_argv() to accept variable arguments. This fixes
14503 a problem where arguments were not getting passed to the CGI via
14504 argv[] when the suexec wrapper was active. [Randy Terbush, Jake Buchholz]
14506 *) Collapse multiple slashes in path URLs to properly apply
14507 handlers defined by <Location>. [Alexei Kosut]
14509 *) Define a sane set of DEFAULT_USER and DEFAULT_GROUP values for AIX.
14511 *) Improve the accuracy of request duration timings by setting
14512 r->request_time in read_request_line() instead of read_request().
14515 *) Reset timeout while reading via get_client_block() in mod_cgi.c
14516 Fixes problem with timed out transfers of large files. [Rasmus Lerdorf]
14518 *) Add the ability to pass different Makefile.tmpl files to Configure
14519 using the -make flag. [Rob Hartill]
14521 *) Fix coredump triggered when sending a SIGHUP to the server caused
14522 by an assertion failure, in turn caused by an uninitialised field in a
14526 *) Add FILEPATH_INFO variable to CGI environment, which is equal to
14527 PATH_INFO from previous versions of Apache (in certain situations,
14528 Apache 1.2's PATH_INFO will be different than 1.1's). [Alexei Kosut]
14529 [later removed in 1.2b11]
14531 *) Add rwrite() function to API to allow for sending strings of
14532 arbitrary length. [Doug MacEachern]
14534 *) Remove rlim_t typedef for NetBSD. Do older versions need this?
14536 *) Defined rlim_t and WANTHSREGEX=yes and fixed waitpid() substitute for
14537 NeXT. [Jim Jagielski]
14539 *) Removed recent modification to promote the status code on internal
14540 redirects, since the correct fix was to change the default log format
14541 in mod_log_config so that it outputs the original status. [Rob Hartill]
14543 Changes with Apache 1.2b2:
14545 *) Update set_signals() to use sigaction() for setting handlers.
14546 This appears to fix a re-entrant problem in the seg_fault()
14547 bus_error() handlers. [Randy Terbush]
14549 *) Changes to allow mod_status compile for OS/2 [Garey Smiley]
14551 *) changes for DEC AXP running OSF/1 v3.0. [Marc Evans]
14553 *) proxy_http.c bugfixes: [Chuck Murcko]
14554 1) fixes possible NULL pointer reference w/NoCache
14555 2) fixes NoCache behavior when using ProxyRemote (ProxyRemote
14556 host would cache nothing if it was in the local domain,
14557 and the local domain was in the NoCache list)
14558 3) Adds Host: header when not available
14559 4) Some code cleanup and clarification
14561 *) mod_include.c bugfixes:
14562 1) Fixed an ommission that caused include variables to not
14563 be parsed in config errmsg directives [Howard Fear]
14564 2) Remove HAVE_POSIX_REGEX cruft [Alexei Kosut]
14565 3) Patch to fix compiler warnings [<perrot lal.in2p3.fr>]
14566 4) Allow backslash-escaping to all quoted text
14567 [Ben Yoshino <ben wiliki.eng.hawaii.edu>]
14568 5) Pass variable to command line if not set in XSSI's env
14571 *) Fix infinite loop when processing Content-language lines in
14572 type-map files. [Alexei Kosut]
14574 *) Closed file-globbing hole in test-cgi script. [Brian Behlendorf]
14576 *) Fixed problem in set_[user|group] that prevented CGI execution
14577 for non-virtualhosts when suEXEC was enabled. [Randy Terbush]
14579 *) Added PORTING information file. [Jim Jagielski]
14581 *) Added definitions for S_IWGRP and S_IWOTH to conf.h [Ben Laurie]
14583 *) Changed default group to "nogroup" instead of "nobody" [Randy Terbush]
14585 *) Fixed define typo of FCNTL_SERIALIZED_ACCEPT where
14586 USE_FCNTL_SERIALIZED_ACCEPT was intended.
14588 *) Fixed additional uses of 0xffffffff where INADDR_NONE was intended,
14589 which caused problems of systems where socket s_addr is >32bits.
14591 *) Added comment to explain (r->chunked = 1) side-effect in
14592 http_protocol.c [Roy Fielding]
14594 *) Replaced use of index() in mod_expires.c with more appropriate
14595 and portable isdigit() test. [Ben Laurie]
14597 *) Updated Configure for ...
14598 OS/2 (DEF_WANTHSREGEX=yes, other code changes)
14599 *-dg-dgux* (bad pattern match)
14600 QNX (DEF_WANTHSREGEX=yes)
14601 *-sunos4* (DEF_WANTHSREGEX=yes, -DUSEBCOPY)
14603 *-unixware211 (new)
14604 and added some user diagnostic info. [Ben Laurie]
14606 *) In helpers/CutRule, replaced "cut" invocation with "awk" invocation
14607 for better portability. [Jim Jagielski]
14609 *) Updated helpers/GuessOS for ...
14610 SCO 5 (recognize minor releases)
14611 SCO UnixWare (braindamaged uname, whatever-whatever-unixware2)
14612 SCO UnixWare 2.1.1 (requires a separate set of #defines in conf.h)
14613 IRIX64 (-sgi-irix64)
14614 ULTRIX (-unknown-ultrix)
14615 SINIX (-whatever-sysv4)
14616 NCR Unix (-ncr-sysv4)
14617 and fixed something in helpers/PrintPath [Ben Laurie]
14619 Changes with Apache 1.2b1
14621 *) Not listed. See <http://www.apache.org/docs/new_features_1_2.html>
14623 Changes with Apache 1.1.1
14625 *) Fixed bug where Cookie module would make two entries in the
14626 logfile for each access [Mark Cox]
14628 *) Fixed bug where Redirect in .htaccess files would cause memory
14629 leak. [Nathan Neulinger]
14631 *) MultiViews now works correctly with AddHandler [Alexei Kosut]
14633 *) Problems with mod_auth_msql fixed [Dirk vanGulik]
14635 *) Fix misspelling of "Anonymous_Authorative" directive in mod_auth_anon.
14637 Changes with Apache 1.1.0
14639 *) Bring NeXT support up to date. [Takaaki Matsumoto]
14641 *) Bring QNX support up to date. [Ben Laurie]
14643 *) Make virtual hosts default to main server keepalive parameters.
14644 [Alexei Kosut, Ben Laurie]
14646 *) Allow ScanHTMLTitles to work with lowercase <title> tags. [Alexei Kosut]
14648 *) Fix missing address family for connect, also remove unreachable statement
14649 in mod_proxy. [Ben Laurie]
14651 *) mod_env now turned on by default in Configuration.tmpl.
14653 *) Bugs which were fixed:
14654 a) yet more mod_proxy bugs [Ben Laurie]
14655 b) CGI works again with inetd [Alexei Kosut]
14656 c) Leading colons were stripped from passwords [<osm interguide.com>]
14657 d) Another fix to multi-method Limit problem [<jk tools.de>]
14659 Changes with Apache 1.1b4
14661 *) r->bytes_sent variable restored. [Robert Thau]
14663 *) Previously broken multi-method <Limit> parsing fixed. [Robert Thau]
14665 *) More possibly unsecure programs removed from the support directory.
14667 *) More mod_auth_msql authentication improvements.
14669 *) VirtualHosts based on Host: headers no longer conflict with the
14672 *) OS/2 compatibility enhancements. [Gary Smiley]
14674 *) POST now allowed to directory index CGI scripts.
14676 *) Actions now work with files of the default type.
14678 *) Bugs which were fixed:
14679 a) more mod_proxy bugs
14680 b) early termination of inetd requests
14681 c) compile warnings on several systems
14682 d) problems when scripts stop reading output early
14684 Changes with Apache 1.1b3
14686 *) Much of cgi-bin and all of cgi-src has been removed, due to
14687 various security holes found and that we could no longer support
14690 *) The "Set-Cookie" header is now special-cased to not merge multiple
14691 instances, since certain popular browsers can not handle multiple
14692 Set-Cookie instructions in a single header. [Paul Sutton]
14694 *) rprintf() added to buffer code, occurrences of sprintf removed.
14697 *) CONNECT method for proxy module, which means tunneling SSL should work.
14698 (No crypto needed) Also a NoCache config directive.
14700 *) Several API additions: pstrndup(), table_unset() and get_token()
14701 functions now available to modules.
14703 *) mod_imap fixups, in particular Location: headers are now complete
14706 *) New "info" module which reports on installed module set through a
14707 special URL, a la mod_status.
14709 *) "ServerPath" directive added - allows for graceful transition
14710 for Host:-header-based virtual hosts.
14712 *) Anonymous authentication module improvements.
14714 *) MSQL authentication module improvements.
14716 *) Status module design improved - output now table-based. [Ben Laurie]
14718 *) htdigest utility included for use with digest authentication
14721 *) mod_negotiation: Accept values with wildcards to be treated with
14722 less priority than those without wildcards at the same quality
14723 value. [Alexei Kosut]
14725 *) Bugs which were fixed:
14726 a) numerous mod_proxy bugs
14727 b) CGI early-termination bug [Ben Laurie]
14728 c) Keepalives not working with virtual hosts
14729 d) RefererIgnore problems
14730 e) closing fd's twice in mod_include (causing core dumps on
14731 Linux and elsewhere).
14733 Changes with Apache 1.1b2
14736 a) core dumps in mod_digest
14737 b) truncated hostnames/ip address in the logs
14738 c) relative URL's in mod_imap map files
14740 Changes with Apache 1.1b1
14742 *) Not listed. See <http://www.apache.org/docs/new_features_1_1.html>
14744 Changes with Apache 1.0.3
14746 *) Internal redirects which occur in mod_dir.c now preserve the
14747 query portion of a request (the bit after the question mark).
14750 *) Escape active characters '<', '>' and '&' in html output in
14751 directory listings, error messages and redirection links.
14754 *) Apache will now work with LynxOS 2.3 and later [Steven Watt]
14756 *) Fix for POSIX compliance in waiting for processes in alloc.c.
14759 *) setsockopt no longer takes a const declared argument [Martijn Koster]
14761 *) Reset timeout timer after each successful fwrite() to the network.
14762 This patch adds a reset_timeout() procedure that is called by
14763 send_fd() to reset the timeout ever time data is written to the net.
14766 *) timeout() signal handler now checks for SIGPIPE and reports
14767 lost connections in a more user friendly way. [Rob Hartill]
14769 *) Location of the "scoreboard" file which used to live in /tmp is
14770 now configurable (for OSes that can't use mmap) via ScoreBoardFile
14771 which works similar to PidFile (in httpd.conf) [Rob Hartill]
14773 *) Include sys/resource.h in the correct place for SunOS4 [Sameer Parekh]
14775 *) the pstrcat call in mod_cookies.c didn't have an ending NULL,
14776 which caused a SEGV with cookies enabled
14778 *) Output warning when MinSpareServers is set to <= 0 and change it to 1
14781 *) Log the UNIX textual error returned by some system calls, in
14782 particular errors from accept() [David Robinson]
14784 *) Add strerror function to util.c for SunOS4 [Randy Terbush]
14786 Changes with Apache 1.0.2
14788 *) patch to get Apache compiled on UnixWare 2.x, recommended as
14789 a temporary measure, pending rewrite of rfc931.c. [Chuck Murcko]
14791 *) Fix get_basic_auth_pw() to set the auth_type of the request.
14794 *) past changes to http_config.c to only use the
14795 setrlimit function on systems defining RLIMIT_NOFILE
14796 broke the feature on SUNOS4. Now defines HAVE_RESOURCE
14797 for SUNOS and prototypes the needed functions.
14799 *) Remove uses of MAX_STRING_LEN/HUGE_STRING_LEN from several routines.
14802 *) Fix use of pointer to scratch memory. [Cliff Skolnick]
14804 *) Merge multiple headers from CGI scripts instead of taking last
14805 one. [David Robinson]
14807 *) Add support for SCO 5. [Ben Laurie]
14809 Changes with Apache 1.0.1
14811 *) Silence mod_log_referer and mod_log_agent if not configured
14814 *) Recursive includes can occur if the client supplies PATH_INFO data
14815 and the server provider uses relative links; as file.html
14816 relative to /doc.shtml/pathinfo is /doc.shtml/file.html. [David Robinson]
14818 *) The replacement for initgroups() did not call {set,end}grent(). This
14819 had two implications: if anything else used getgrent(), then
14820 initgroups() would fail, and it was consuming a file descriptor.
14823 *) On heavily loaded servers it was possible for the scoreboard to get
14824 out of sync with reality, as a result of a race condition.
14825 The observed symptoms are far more Apaches running than should
14826 be, and heavy system loads, generally followed by catastrophic
14827 system failure. [Ben Laurie]
14829 *) Fix typo in license. [David Robinson]
14831 Changes with Apache 1.0.0 23 Nov 1995
14833 *) Not listed. See <http://www.apache.org/docs/new_features_1_0.html>
14835 Changes with Apache 0.8.16 05 Nov 1995
14837 *) New man page for 'httpd' added to support directory [David Robinson]
14839 *) .htgroup files can have more than one line giving members for a
14840 given group (each must have the group name in front), for NCSA
14841 back-compatibility [Robert Thau]
14843 *) Mutual exclusion around accept() is on by default for SVR4 systems
14844 generally, since they generally can't handle multiple processes in
14845 accept() on the same socket. This should cure flaky behavior on
14846 a lot of those systems. [David Robinson]
14848 *) AddType, AddEncoding, and AddLanguage directives take multiple
14849 extensions on a single command line [David Robinson]
14851 *) UserDir can be disabled for a given virtual host by saying
14852 "UserDir disabled" in the <VirtualHost> section --- it was a bug
14853 that this didn't work. [David Robinson]
14855 *) Compiles on QNX [Ben Laurie]
14857 *) Corrected parsing of ctime time format [David Robinson]
14859 *) httpd does a perror() before exiting if it can't log its pid
14860 to the PidFile, to make diagnosing the error a bit easier.
14863 *) <!--#include file="..."--> can no longer include files in the
14864 parent directory, for NCSA back-compatibility. [David Robinson]
14866 *) '~' is *not* escaped in URIs generated for directory listings
14869 *) Eliminated compiler warning in the imagemap module [Randy Terbush]
14871 *) Fixed bug involving handling URIs with escaped %-characters
14872 in redirects [David Robinson]
14874 Changes with Apache 0.8.15 14 Oct 1995
14876 *) Switched to new, simpler license
14878 *) Eliminated core dumps with improperly formatted DBM group files [Mark Cox]
14880 *) Don't allow requests for ordinary files to have PATH_INFO [Ben Laurie]
14882 *) Reject paths containing %-escaped '%' or null characters [David Robinson]
14884 *) Correctly handles internal redirects to files with names containing '%'
14887 *) Repunctuated some error messages [Aram Mirzadeh, Andrew Wilson]
14889 *) Use geteuid() rather than getuid() to see if we have root privilege,
14890 so that server correctly resets privilege if run setuid root. [Andrew
14893 *) Handle ftp: and telnet: URLs correctly in imagemaps (built-in module)
14896 *) Fix relative URLs in imagemap files [Randy Terbush]
14898 *) Somewhat better fix for the old "Alias /foo/ /bar/" business
14901 *) Don't repeatedly open the ErrorLog if a bunch of <VirtualHost>
14902 entries all name the same one. [David Robinson]
14904 *) Fix directory listings with filenames containing unusual characters
14907 *) Better URI-escaping for generated URIs in directories with filenames
14908 containing unusual characters [Ben Laurie]
14910 *) Fixed potential FILE* leak in http_main.c [Ben Laurie]
14912 *) Unblock alarms on error return from spawn_child() [David Robinson]
14914 *) Sample Config files have extra note for SCO users [Ben Laurie]
14916 *) Configuration has note for HP-UX users [Rob Hartill]
14918 *) Eliminated some bogus Linux-only #defines in conf.h [Aram Mirzadeh]
14920 *) Nuked bogus #define in httpd.h [David Robinson]
14922 *) Better test for whether a system has setrlimit() [David Robinson]
14924 *) Calls update_child_status() after reopen_scoreboard() [David Robinson]
14926 *) Doesn't send itself SIGHUP on startup when run in the -X debug-only mode
14929 Changes with Apache 0.8.14 19 Sep 1995
14931 *) Compiles on SCO ODT 3.0 [Ben Laurie]
14933 *) AddDescription works (better) [Ben Laurie]
14935 *) Leaves an intelligible error diagnostic when it can't set group
14936 privileges on standalone startup [Andrew Wilson]
14938 *) Compiles on NeXT again --- the 0.8.13 RLIMIT patch was failing on
14939 that machine, which claims to be BSD but does not support RLIMIT.
14942 *) gcc -Wall no longer complains about an unused variable when util.c
14943 is compiled with -DMINIMAL_DNS [Andrew Wilson]
14945 *) Nuked another compiler warning for -Wall on Linux [Aram Mirzadeh]
14947 Changes with Apache 0.8.13 07 Sep 1995
14949 *) Make IndexIgnore *work* (ooops) [Jarkko Torppa]
14951 *) Have built-in imagemap code recognize & honor Point directive [James
14954 *) Generate cleaner directory listings in directories with a mix of
14955 long and short filenames [Rob Hartill]
14957 *) Properly initialize dynamically loaded modules [Royston Shufflebotham]
14959 *) Properly default ServerName for virtual servers [Robert Thau]
14961 *) Rationalize handling of BSD in conf.h and elsewhere [Randy Terbush,
14962 Paul Richards and a cast of thousands...]
14964 *) On self-identified BSD systems (we don't try to guess any more),
14965 allocate a few extra file descriptors per virtual host with setrlimit,
14966 if we can, to avoid running out. [Randy Terbush]
14968 *) Write 22-character lock file name into buffer with enough space
14969 on startup [Konstantin Olchanski]
14971 *) Use archaic setpgrp() interface on NeXT, which requires it [Brian
14974 *) Suppress -Wall warning by casting const away in util.c [Aram Mirzadeh]
14976 *) Suppress -Wall warning by initializing variable in negotiation code
14977 [Tobias Weingartner]
14979 Changes with Apache 0.8.12 31 Aug 1995
14981 *) Doesn't pause three seconds after including a CGI script which is
14982 too slow to die off (this is done by not even trying to kill off
14983 subprocesses, including the SIGTERM/pause/SIGKILL routine, until
14984 after the entire document has been processed). [Robert Thau]
14986 *) Doesn't do SSI if Options Includes is off. (Ooops). [David Robinson]
14988 *) Options IncludesNoExec allows inclusion of at least text/* [Roy Fielding]
14990 *) Allows .htaccess files to override <Directory> sections naming the
14991 same directory [David Robinson]
14993 *) Removed an efficiency hack in sub_req_lookup_uri which was
14994 causing certain extremely marginal cases (e.g., ScriptAlias of a
14995 *particular* index.html file) to fail. [David Robinson]
14997 *) Doesn't log an error when the requested URI requires
14998 authentication, but no auth header line was supplied by the
14999 client; this is a normal condition (the client doesn't no auth is
15000 needed here yet). [Robert Thau]
15002 *) Behaves more sanely when the name server loses its mind [Sean Welch]
15004 *) RFC931 code compiles cleanly on old BSDI releases [Randy Terbush]
15006 *) RFC931 code no longer passes out name of prior clients on current
15007 requests if the current request came from a server that doesn't
15008 do RFC931. [David Robinson]
15010 *) Configuration script accepts "Module" lines with trailing whitespace.
15013 *) Cleaned up compiler warning from mod_access.c [Robert Thau]
15015 *) Cleaned up comments in mod_cgi.c [Robert Thau]
15017 Changes with Apache 0.8.11 24 Aug 1995
15019 *) Wildcard <Directory> specifications work. [Robert Thau]
15021 *) Doesn't loop for buggy CGI on Solaris [Cliff Skolnick]
15023 *) Symlink checks (FollowSymLinks off, or SymLinkIfOwnerMatch) always check
15024 the file being requested itself, in addition to the directories leading
15025 up to it. [Robert Thau]
15027 *) Logs access failures due to symlink checks or invalid client address
15028 in the error log [Roy Fielding, Robert Thau]
15030 *) Symlink checks deal correctly with systems where lstat of
15031 "/path/to/some/link/" follows the link. [Thau, Fielding]
15033 *) Doesn't reset DirectoryIndex to 'index.html' when
15034 other directory options are set in a .htaccess file. [Robert Thau]
15036 *) Clarified init code and nuked bogus warning in mod_access.c
15037 [Florent Guillaume]
15039 *) Corrected several directives in sample srm.conf
15040 --- includes corrections to directory indexing icon-related directives
15041 (using unknown.gif rather than unknown.xbm as the DefaultIcon, doing
15042 icons for encodings right, and turning on AddEncoding by default).
15045 *) Corrected descriptions of args to AddIcon and AddAlt in command table
15048 *) INSTALL & README mention "contributed modules" directory [Brian
15051 *) Fixed English in the license language... "for for" --> "for".
15054 *) Fixed ScriptAlias/Alias interaction by moving ScriptAlias handling to
15055 mod_alias.c, merging it almost completely with handling of Alias, and
15056 adding a 'notes' field to the request_rec which allows the CGI module
15057 to discover whether the Alias module has put this request through
15058 ScriptAlias (which it needs to know for back-compatibility, as the old
15059 NCSA code did not check Options ExecCGI in ScriptAlias directories).
15062 Changes with Apache 0.8.10 18 Aug 1995
15064 *) AllowOverride applies to the named directory, and not just
15065 subdirectories. [David Robinson]
15067 *) Do locking for accept() exclusion (on systems that need it)
15068 using a special file created for the purpose in /usr/tmp, and
15069 not the error log; using the error log causes real problems
15070 if it's NFS-mounted; this is known to be the cause of a whole
15071 lot of "server hang" problems with Solaris. [David Robinson;
15072 thanks to Merten Schumann for help diagnosing the problem].
15074 Changes with Apache 0.8.9 12 Aug 1995
15076 *) Compiles with -DMAXIMUM_DNS ---- ooops! [Henrik Mortensen]
15078 *) Nested includes see environment variables of the including document,
15079 for NCSA bug-compatibility (some sites have standard footer includes
15080 which try to print out the last-modified date). [Eric Hagberg/Robert
15083 *) <!--exec cgi="/some/uri/here"--> always treats the item named by the
15084 URI as a CGI script, even if it would have been treated as something
15085 else if requested directly, for NCSA back-compatibility. (Note that
15086 this means that people who know the name of the script can see the
15087 code just by asking for it). [Robert Thau]
15089 *) New version of dbmmanage script included in support directory as
15092 *) Check if scoreboard file couldn't be opened, and say so, rather
15093 then going insane [David Robinson]
15095 *) POST to CGI works on A/UX [Jim Jagielski]
15097 *) AddIcon and AddAlt commands work properly [Rob Hartill]
15099 *) NCSA server push works properly --- the Arena bug compatibility
15100 workaround, which broke it, is gone (use -DARENA_BUG_WORKAROUND
15101 if you still want the workaround). [Rob Hartill]
15103 *) If client didn't submit any Accept-encodings, ignore encodings in
15104 content negotiation. (NB this will all have to be reworked anyway
15105 for the new HTTP draft). [Florent Guillaume]
15107 *) Don't dump core when trying to log timed-out requests [Jim Jagielski]
15109 *) Really honor CacheNegotiatedDocs [Florent Guillaume]
15111 *) Give Redirect priority over Alias, for NCSA bug compatibility
15114 *) Correctly set PATH_TRANSLATED in all cases from <!--#exec cmd=""-->,
15115 paralleling earlier bug fix for CGI [David Robinson]
15117 *) If DBM auth is improperly configured, report a server error and don't
15120 *) Deleted FCNTL_SERIALIZED_ACCEPTS from conf.h entry for A/UX;
15121 it seems to work well enough without it (even in a 10 hits/sec
15122 workout), and the overhead for the locking under A/UX is
15123 alarmingly high (though it is very low on other systems).
15124 [Eric Hagberg, Jim Jagielski]
15126 *) Fixed portability problems with mod_cookies.c [Cliff Skolnick]
15128 *) Further de-Berklize mod_cookies.c; change the bogus #include. [Brian
15129 Behlendorf/Eric Hagberg]
15131 *) More improvements to default Configuration for A/UX [Jim Jagielski]
15133 *) Compiles clean on NEXT [Rob Hartill]
15135 *) Compiles clean on SGI [Robert Thau]
15137 Changes with Apache 0.8.8 08 Aug 1995
15139 *) SunOS library prototypes now never included unless explicitly
15140 requested in the configuration (via -DSUNOS_LIB_PROTOTYPES);
15141 people using GNU libc on SunOS are screwed by prototypes for the
15144 (Those who wish to compile clean with gcc -Wall on a standard
15145 SunOS setup need the prototypes, and may obtain them using
15146 -DSUNOS_LIB_PROTOTYPES. Those wishing to use -Wall on a system
15147 with nonstandard libraries are presumably competent to make their
15150 *) Strips trailing '/' characters off both args to the Alias command,
15151 to make 'Alias /foo/ /bar/' work.
15153 Changes with Apache 0.8.7 03 Aug 1995
15155 *) Don't hang when restarting with a child from 'TransferLog "|..."' running
15156 [reported by David Robinson]
15158 *) Compiles clean on OSF/1 [David Robinson]
15160 *) Added some of the more recent significant changes (AddLanguage stuff,
15161 experimental LogFormat support) to CHANGES file in distribution root
15164 Changes with Apache 0.8.6 02 Aug 1995
15166 *) Deleted Netscape reload workaround --- it's in violation of HTTP specs.
15167 (If you actually wanted a conditional GET which bypassed the cache, you
15168 couldn't get it). [Reported by Roy Fielding]
15170 *) Properly terminate headers on '304 Not Modified' replies to conditional
15171 GETs --- no browser we can find cares much, but the CERN proxy chokes.
15172 [Reported by Cliff Skolnick; fix discovered independently by Rob Hartill]
15174 *) httpd -v doesn't call itself "Shambhala". [Reported by Chuck Murcko]
15176 *) SunOS lib-function prototypes in conf.h conditionalized on __GNUC__,
15177 not __SUNPRO_C (they're needed to quiet gcc -Wall, but acc chokes on 'em,
15178 and older versions don't set the __SUNPRO_C preprocessor variable). On
15179 all other systems, these are never used anyway. [Reported by Mark Cox].
15181 *) Scoreboard file (/tmp/htstatus.*) no longer publically writable.
15183 Changes with Apache 0.8.5 01 Aug 1995
15185 *) Added last-minute configurable log experiment, as optional module
15187 *) Correctly set r->bytes_sent for HTTP/0.9 requests, so they get logged
15188 properly. (One-line fix to http_protocol.c).
15190 *) Work around bogus behavior when reloading from Netscape.
15191 It's Netscape's bug --- for some reason they expect a request with
15192 If-modified-since: to not function as a conditional GET if it also
15193 comes with Pragma: no-cache, which is way out of line with the HTTP
15194 spec (according to Roy Fielding, the redactor).
15196 *) Added parameter to set maximum number of server processes.
15198 *) Added patches to make it work on A/UX. A/UX is *weird*. [Eric Hagberg,
15201 *) IdentityCheck bugfix [Chuck Murcko].
15203 *) Corrected cgi-src/Makefile entry for new imagemap script. [Alexei Kosut]
15205 *) More sample config file corrections; add extension to AddType for
15206 *.asis, move AddType generic description to its proper place, and
15207 fix miscellaneous typos. [ Alexei Kosut ]
15209 *) Deleted the *other* reference to the regents from the Berkeley
15210 legal disclaimer (everyplace).
15212 *) Nuked Shambhala name from src/README; had already cleaned it out
15213 of everywhere else.
15215 Changes with Apache 0.8.4
15217 *) Changes to server-pool management parms --- renamed current
15218 StartServers to MinSpareServers, created separate StartServers
15219 parameter which means what it says, and renamed MaxServers to
15220 MaxSpareServers (though the old name still works, for NCSA 1.4
15221 back-compatibility). The old names were generally regarded as
15222 too confusing. Also altered "docs" in sample config files.
15224 *) More improvements to default config files ---
15225 sample directives (commented out) for XBitHack, BindAddress,
15226 CacheNegotiatedDocs, VirtualHost; decent set of AddLanguage
15227 defaults, AddTypes for send-as-is and imagemap magic types, and
15228 improvements to samples for DirectoryIndex [Alexei Kosut]
15230 *) Yet more improvements to default config files --- changes to
15231 Alexei's sample AddLanguage directives, and sample LanguagePriority
15232 [ Florent Guillaume ]
15234 *) Set config file locations properly if not set in httpd.conf
15237 *) Don't escape URIs in internal redirects multiple times; don't
15238 do that when translating PATH_INFO to PATH_TRANSLATED either.
15241 *) Corrected spelling of "Required" in 401 error reports [Andrew Wilson]
15243 Changes with Apache 0.8.3
15245 *) Edited distribution README to *briefly* summarize installation
15246 procedures, and give a pointer to the INSTALL file in the src/
15249 *) Upgraded imagemap script in cgi-bin to 1.8 version from more
15250 recent NCSA distributions.
15252 *) Bug fix to previous bug fix --- if .htaccess file and <Directory>
15253 exist for the same directory, use both and don't segfault. [Reported
15256 *) Proper makefile dependencies [David Robinson]
15258 *) Note (re)starts in error log --- reported by Rob Hartill.
15260 *) Only call no2slash() after get_path_info() has been done, to
15261 preserve multiple slashes in the PATH_INFO [NCSA compatibility,
15262 reported by Andrew Wilson, though this one is probably a real bug]
15264 *) Fixed mod_imap.c --- relative paths with base_uri referer don't
15265 dump core when Referer is not supplied. [Randy Terbush]
15267 *) Lightly edited sample config files to refer people to our documentation
15268 instead of NCSA's, and to list Rob McCool as *original* author (also
15269 deleted his old, and no doubt non-functional email address). Would be
15270 nice to have examples of new features...
15272 Changes with Apache 0.8.2 19 Jul 1995
15274 *) Added AddLanuage code [Florent Guillaume]
15276 *) Don't say "access forbidden" when a CGI script is not found. [Mark Cox]
15278 *) All sorts of problems when MultiViews finds a directory. It would
15279 be nice if mod_dir.c was robust enough to handle that, but for now,
15280 just punt. [reported by Brian Behlendorf]
15282 *) Wait for all children on restart, to make sure that the old socket
15283 is gone and we can reopen it. [reported by Randy Terbush]
15285 *) Imagemap module is enabled in default Configuration
15287 *) RefererLog and UserAgentLog modules properly default the logfile
15290 *) Mark Cox's mod_cookies added to the distribution as an optional
15291 module (commented out in the default Configuration, and noted as
15292 an experiment, along with mod_dld). [Mark Cox]
15294 *) Compiles on ULTRIX (a continuing battle...). [Robert Thau]
15296 *) Fixed nasty bug in SIGTERM handling [reported by Randy Terbush]
15298 *) Changed "Shambhala" to "Apache" in API docs. [Robert Thau]
15300 *) Added new, toothier legal disclaimer. [Robert Thau; copied from BSD
15303 Changes with Apache 0.8.1
15305 *) New imagemap module [Randy Terbush]
15307 *) Replacement referer log module with NCSA-compatible RefererIgnore
15308 [Matthew Gray again]
15310 *) Don't mung directory listings with very long filenames.
15311 [Florent Guillaume]
15313 Changes with Apache 0.8.0 (nee Shambhala 0.6.2) 16 Jul 1995
15315 *) New config script. See INSTALL for info. [Robert Thau]
15317 *) Scoreboard mechanism for regulating the number of extant server
15318 processes. MaxServers and StartServers defaults are the same as
15319 for NCSA, but the meanings are slightly different. (Actually,
15320 I should probably lower the MaxServers default to 10).
15322 Before asking for a new connection, each server process checks
15323 the number of other servers which are also waiting for a
15324 connection. If there are more than MaxServers, it quietly dies
15325 off. Conversely, every second, the root, or caretaker, process
15326 looks to see how many servers are waiting for a new connection;
15327 if there are fewer than StartServers, it starts a new one. This
15328 does not depend on the number of server processes already extant.
15329 The accounting is arranged through a "scoreboard" file, named
15330 /tmp/htstatus.*, on which each process has an independent file
15331 descriptor (they need to seek without interference).
15333 The end effect is that MaxServers is the maximum number of
15334 servers on an *inactive* server machine, but more will be forked
15335 off to handle unusually heavy loads (or unusually slow clients);
15336 these will die off when they are no longer needed --- without
15337 reverting to the overhead of full forking operation. There is a
15338 hard maximum of 150 server processes compiled in, largely to
15339 avoid forking out of control and dragging the machine down.
15340 (This is arguably too high).
15342 In my server endurance tests, this mechanism did not appear to
15343 impose any significant overhead, even after I forced it to put the
15344 scoreboard file on a normal filesystem (which might have more
15345 overhead than tmpfs). [Robert Thau]
15347 *) Set HTTP_FOO variables for SSI <!--#exec cmd-->s, not just CGI scripts.
15350 *) Read .htaccess files even in directory with <Directory> section.
15351 (Former incompatibility noted on mailing list, now fixed). [Robert
15354 *) "HEAD /" gives the client a "Bad Request" error message, rather
15355 than trying to send no body *and* no headers. [Cliff Skolnick].
15357 *) Don't produce double error reports for some very obscure cases
15358 mainly involving auth configuration (the "all modules decline to
15359 handle" case which is a sure sign of a server bug in most cases,
15360 but also happens when authentication is badly misconfigured).
15363 *) Moved FCNTL_SERIALIZED_ACCEPT defines into conf.h (that's what
15364 it's *for*, and this sort of thing really shouldn't be cluttering
15365 up the Makefile). [Robert Thau]
15367 *) Incidental code cleanups in http_main.c --- stop dragging
15368 sa_client around; just declare it where used. [Robert Thau]
15370 *) Another acc-related fix. (It doesn't like const char
15371 in some places...). [Mark Cox]
15373 Changes with Shambhala 0.6.1 13 Jul 1995
15375 *) Fixed auth_name-related typos in http_core.c [Brian Behlendorf]
15376 Also, fixed auth typo in http_protocol.c unmasked by this fix.
15378 *) Compiles clean with acc on SunOS [Paul Sutton]
15380 *) Reordered modules in modules.c so that Redirect takes priority
15381 over ScriptAlias, for NCSA bug-compatibility [Rob Hartill] ---
15382 believe it or not, he has an actual site with a ScriptAlias and
15383 a Redirect declared for the *exact same directory*. Even *my*
15384 compatibility fetish wouldn't motivate me to fix this if the fix
15385 required any effort, but it doesn't, so what the hey.
15387 *) Fixed to properly default several server_rec fields for virtual
15388 servers from the corresponding fields in the main server_rec.
15389 [Cliff Skolnick --- 'port' was a particular irritant].
15391 *) No longer kills off nph- child processes before they are
15392 finished sending output. [Matthew Gray]
15394 Changes with Shambhala 0.6.0 10 Jul 1995
15396 *) Two styles of timeout --- hard and soft. soft_timeout()s just put
15397 the connection to the client in an "aborted" state, but otherwise
15398 allow whatever handlers are running to clean up. hard_timeout()s
15399 abort the request in progress completely; anything not tied to some
15400 resource pool cleanup will leak. They're still around because I
15401 haven't yet come up with a more elegant way of handling
15402 timeouts when talking to something that isn't the client. The
15403 default_handler and the dir_handler now use soft timeouts, largely
15404 so I can test the feature. [Robert Thau]
15406 *) TransferLog "| my_postprocessor ..." seems to be there. Note that
15407 the case of log handlers dying prematurely is probably handled VERY
15408 gracelessly at this point, and if the logger stops reading input,
15409 the server will hang. (It is known to correctly restart the
15410 logging process on server restart; this is (should be!) going through
15411 the same SIGTERM/pause/SIGKILL routine used to ding an errant CGI
15412 script). [Robert Thau]
15414 *) asis files supported (new module). [Robert Thau]
15416 *) IdentityCheck code is compiled in, but has not been tested. (I
15417 don't know anyone who runs identd). [Robert Thau]
15419 *) PATH_INFO and PATH_TRANSLATED are not set unless some real PATH_INFO
15420 came in with the request, for NCSA bug-compatibility. [Robert Thau]
15422 *) Don't leak the DIR * on HEAD request for a directory. [Robert Thau]
15424 *) Deleted the block_alarms() stuff from dbm_auth; no longer necessary,
15425 as timeouts are not in scope. [Robert Thau]
15427 *) quoted-string args in config files now handled correctly (doesn't drop
15428 the last character). [Robert Thau; reported by Randy Terbush]
15430 *) Fixed silly typo in http_main.c which was suddenly fatal in HP-UX.
15431 How the hell did it ever work? [Robert Thau; reported by Rob Hartill]
15433 *) mod_core.c --- default_type returns DEFAULT_TYPE (the compile-time
15434 default default type); the former default default behavior when all
15435 type-checkers defaulted had been a core dump. [Paul Sutton]
15437 *) Copy filenames out of the struct dirent when indexing
15438 directories. (On Linux, readdir() returns a pointer to the same
15439 memory area every time). Fix is in mod_dir.c. [Paul Sutton]
15441 Changes with Shambhala 0.5.3 [not released]
15443 *) Default response handler notes "file not found" in the error log,
15444 if the file was not found. [Cliff Skolnick].
15446 *) Another Cliff bug --- "GET /~user" now properly redirects (the userdir
15447 code no longer sets up bogus PATH_INFO which fakes out the directory
15448 handler). [Cliff Skolnick]
15450 Changes with Shambhala 0.5.2 06 Jul 1995
15452 *) Changes to http_main.c --- root server no longer plays silly
15453 games with SIGCHLD, and so now detects and replaces dying
15454 children. Child processes just die on SIGTERM, without taking
15455 the whole process group with them. Potential problem --- if any
15456 child process refuses to die, we hang in restart.
15457 MaxRequestsPerChild may still not work, but it certainly works
15458 better than it did before this! [Robert Thau]
15460 *) mod_dir.c bug fixes: ReadmeName and HeaderName
15461 work (or work better, at least); over-long description lines
15462 properly terminated. [Mark Cox]
15464 *) http_request.c now calls unescape_url() more places where it
15465 should [Paul Sutton].
15467 *) More directory handling bugs (reported by Cox)
15468 Parent Directory link is now set correctly. [Robert Thau]
15470 Changes with Shambhala 0.5.1 04 Jul 1995
15472 *) Generalized cleanup interface in alloc.c --- any function can be
15473 registered with alloc.c as a cleanup for a resource pool;
15474 tracking of files and file descriptors has been reimplemented in
15475 terms of this interface, so I can give it some sort of a test.
15478 *) More changes in alloc.c --- new cleanup_for_exec() function,
15479 which tracks down and closes all file descriptors which have been
15480 registered with the alloc.c machinery before the server exec()s a
15481 child process for CGI or <!--#exec-->. CGI children now get
15482 started with exactly three file descriptors open. Hopefully,
15483 this cures the problem Rob H. was having with overly persistent
15484 CGI connections. [Robert Thau]
15486 *) Mutual exclusion around the accept() in child_main() --- this is
15487 required on at least SGI, Solaris and Linux, and is #ifdef'ed in
15488 by default on those systems only (-DFCNTL_SERIALIZED_ACCEPT).
15489 This uses fcntl(F_SETLK,...) on the error log descriptor because
15490 flock() on that descriptor won't work on systems which have BSD
15491 flock() semantics, including (I think) Linux 1.3 and Solaris.
15493 This does work on SunOS (when the server is idle, only one
15494 process in the pool is waiting on accept()); it *ought* to work
15495 on the other systems. [Robert Thau]
15497 *) FreeBSD and BSDI portability tweaks [Chuck Murcko]
15499 *) sizeof(*sa_client) bugfix from [Rob Hartill]
15501 *) pstrdup(..., NULL) returns NULL, [Randy Terbush]
15503 *) block_alarms() to avoid leaking the DBM* in dbm auth (this should
15504 be unnecessary if I go to the revised timeout-handling scheme).
15507 *) For NCSA bug-compatibility, set QUERY_STRING env var (to a null
15508 string) even if none came in with the request. [Robert Thau]
15510 *) CHANGES file added to distribution ;-).
15512 Changes with Shambhala 0.4.5
15514 *) mod_dld --- early dynamic loading support [rst]
15515 *) Add wildcard content handlers for XBITHACK; default_hander now
15516 invoked with that mechanism (as a handler hanging off mod_core) [rst]
15517 *) XBITHACK supported as a wildcard content-handler, and
15518 configurable at run-time (not just at compile time, as in the
15519 "patchy server" releases) [rst]
15521 Changes with Shambhala 0.4.4 30 Jun 1995
15523 *) Fixed basic thinkos in mod_dbm_auth.c [rst, reported by Mark Cox]
15524 *) Handle Addtype x/y .z [rst, reported by Cox]
15526 Changes with Shambhala 0.4.3
15528 *) Fixed very dumb bug in mod_alias; "Alias" and "Redirect" are not
15529 synonymous [rst, terbush]
15531 Changes with Shambhala 0.4.1 28 Jun 1995
15533 *) First-cut virtual host implementation; some refit in the config
15534 reading code, and log management, was necessary to support this [rst]
15535 *) Sub-pool machinery, originally added to avoid excessive storage
15536 allocation on listings of large directories (which turned out to
15537 be the problem that the 0.3 storage accounting was added to
15538 find). Subrequests and mod_dir changed to use subpools. [rst]
15539 *) More memory debugging --- free list consistency checks. [rst]
15540 *) Added err_headers to request_rec, with support elsewhere [rst]
15541 *) Other fixes to minor bugs in mod_dir and mod_includes [rst, terbush]
15543 Changes with Shambhala 0.3 19 Jun 1995
15545 *) Switch ONE_PROCESS to a runtime command-line option (-X)
15546 *) Don't compile in mod_ai_backcompat by default
15547 *) Switch name of server from Apache to Shambhala in Makefile
15548 *) Add some accounting routines to track memory usage in the pools,
15551 Changes with Shambhala 0.2
15553 *) Set DOCUMENT_ROOT CGI variable
15554 *) Add single-process debugging, as a compile-time option (ONE_PROCESS)
15555 *) Add critical section protection to handling of cleanup structures
15557 *) Significant code reorg within the server core to group related
15558 functions together [rst]
15559 *) Correctly handle clients that hang up before sending any request
15561 *) Replace dying child processes. [rst]
15563 Changes with Shambhala 0.1 12 Jun 1995
15565 Major rewrite of the pre-existing "patchy server" codebase, by
15566 Robert Thau (rst). Significant portions of the server code, such
15567 as configuration-file handling and HTTP authentication support,
15568 were ripped out and rewritten from scratch. Code that was not
15569 completely rewritten was significantly altered.
15571 Major changes with this release include:
15573 *) Introduction of the module API; in request handling, the central
15574 machinery just dispatches to various modules, which actually do
15575 most of the work. Configuration handling is similar --- modules
15576 declare their own commands, and the central machinery just
15577 dispatches to them.
15579 API features from shambhala/0.1 were substantially unchanged in
15580 Apache 1.0 and 1.1. (1.0 API features not yet present in this
15581 release, such as wildcard handlers and subpools, were added in
15582 subsequent Shambhala releases, and were also generally rst's
15585 *) This release included the following modules:
15587 mod_access (access control --- allow and deny directives),
15588 mod_alias (Alias and Redirect commands),
15589 mod_auth (straight HTTP authentication, based on flat-files)
15590 mod_auth_dbm (same, with dbm files)
15591 mod_cgi (CGI scripts and, in this release, ScriptAlias)
15592 mod_common_log (CLF access logs; later renamed mod_log_common)
15593 mod_dir (directory indexing)
15594 mod_include (server-side includes)
15595 mod_mime (AddType directives)
15596 mod_negotiation (content negotiation)
15597 mod_userdir (support for users' public_html directories)
15599 It also included a mod_ai_backcompat, which was a private hack
15600 for back-compatibility with rst's own AI-lab servers.
15602 All of these modules were substantially complete, and functional
15603 or nearly so (a few, which implemented features not in use at
15604 Thau's site, required patches of a few lines).
15606 *) sub-request machinery, to allow modules to determine how other
15607 modules would assign MIME types to a given file, or optionally
15608 serve its content (this is heavily used by mod_dir, mod_include
15609 and mod_negotiation).
15611 *) Resource pool system for keeping track of memory allocated and
15612 files opened in service of a particular request. Much of the
15613 code in the modules (when they weren't rewrites) was adjusted to
15614 replace a pervasive convention of using fixed-size buffers on
15615 the stack with an equally pervasive convention of using memory
15616 allocated with palloc().
15618 *) Reorganization of data structures associated with a given
15619 request to eliminate use of global variables and the troublesome
15620 unmunge_name function (used in NCSA and early Apache releases to
15621 attempt to determine the URI which mapped to a given filename
15622 --- a difficult proposition, given that it is easy to produce
15623 setups in which multiple URIs map to the same file).
15625 *) Source files renamed and rearranged
15627 *) Very simple pre-forking behavior --- parent process forked off a
15628 fixed number of children, and then just waited for SIGHUP.
15630 *) Other more minor changes too numerous to list.
15632 This release included modified versions of a lot of code from the
15633 Apache 0.6.4 public release, plus an early pre-forking patch
15634 codeveloped by Robert Thau and Rob Hartill.
15636 Changes with Apache 0.7.3 20 Jun 1995
15638 *) There were a bunch of changes between Apache 0.6.4 and 0.7.3 that
15639 were incorporated by Rob Hartill on the main branch while Robert Thau
15640 worked on the Shambhala rewrite above. Most were merged into the
15641 Shambala architecture after Apache 0.8.0.
15643 Changes with Apache 0.6.4 13 May 1995
15645 *) Patches by Rob Hartill, Cliff Skolnick, Randy Terbush, Robert Thau,
15648 Changes with Apache 0.5.1 10 Apr 1995
15650 Changes with Apache 0.4 02 Apr 1995
15652 *) Patches by Brian Behlendorf, Andrew Wilson, Robert Thau,
15655 Changes with Apache 0.3 24 Mar 1995
15657 *) Patches by Robert Thau, David Robinson, Rob Hartill, and
15660 Changes with Apache 0.2 18 Mar 1995
15662 *) Based on NCSA httpd 1.3 by Rob McCool and patches by CERT,
15663 Roy Fielding, Robert Thau, Nicolas Pioch, David Robinson,
15664 Brian Behlendorf, Rob Hartill, and Cliff Skolnick.
