1 Changes with Apache 2.0.26-dev
3 *) Fix a segfault with mod_include when r->path_info is not set
4 (which is the case with mod_proxy). [Ian Holsman <ianh@cnet.com>]
6 *) Add -X functionality back. This indicates to all MPMs and any other
7 part of Apache that it should run in "debug" mode. [Justin Erenkrantz]
9 *) Some initial support for the cygwin platform [prefork only].
10 This is not to be confused with support for the WinNT/Win32
11 platform, which is the recommended configuration for native
12 Win32 users. The cygwin platform support is recommended for
13 cygwin platform users. [Stipe Tolj <tolj@wapme-systems.de>]
15 *) Changed syntax of Set{Input|Output}Filter. The list of filters
16 must be semicolon delimited (if more than one filter is given.)
17 The Set{Input|Output}Filter directive now overrides a parent
18 container's directive (e.g. SetInputFilter in <Directory /web/foo>
19 will override any SetInputFilter directive in <Directory /web>.)
20 This new syntax is more consistent with Add{Input|Output}Filter
21 directives defined in mod_mime. Also cures a bug in prior releases
22 where the Set{Input|Output}Filter directive would corrupt the
23 global configuration if the multiple directives were nested.
26 *) Cured what's ailed mime for quite some time. If an AddSomething
27 was given in the configuration (Language, Charset, Handler or
28 Encoding) Apache would set the content type as given by AddType,
29 but refused to check the mime.types file if AddType wasn't given
30 for that specific extension. Setting the AddHandler for .html
31 without setting the AddType text/html html would cause Apache to
32 use the default content type. [William Rowe]
34 *) Added some bulletproofing to memory allocation in the LDAP cache
35 code. [Graham Leggett]
37 Changes with Apache 2.0.25
39 *) Move the installed /manual directory out of the /htdocs/ tree, so
40 that it can be kept more independently from the remaining document
41 root. The "Alias /manual ..." already allowed for easy projection
42 into existing private document trees. [Martin Kraemer]
44 *) Add specified user attributes to the environment when using
45 mod_auth_ldap. This allows you to use mod_include to embed specified
46 user attributes in a page like so:
47 Hello <!--#echo var="AUTHENTICATE_CN"-->, how are you?
50 *) Fix a performance problem with the worker MPM. We now create
51 transaction pools once, and re-use them for each connection.
52 [Aaron Bannert <aaron@clove.org>]
54 *) Modfied mod_mime to prevent mod_negotation from serving a multiview
55 of a 'handler' or 'filter', so that any filename extension that does
56 not contribute to the negotiated metadata can't be served without
57 an explicit request. E.g., if the .Z extension is associated with
58 an unzip filter, the user request somefile.Z.html, mod_negotiation
59 won't serve it. It can serve somefile.Z.html when somefile.Z is
60 requested, since the .Z extension is explictly requested, if the
61 .html extension is associated with ContentType text/html.
64 *) Introduce the AddInputFilter filter[;filter...] ext [ext...]
65 and corresponding AddOutputFilter syntax, to insert one or more
66 filters by mod_mime filename extension processing.
69 *) Fix a growing connection pool in core_output_filter() for
70 keepalive requests. [Jeff Trawick]
72 *) Moved split_and_pass_pretag_buckets back to being a
73 macro at Ryans's request. Removed the return from it
74 by setting and returning a return code instead. Updated
75 the code to check the return code from the macro and
76 do the right thing. [Paul J. Reder]
78 *) Fix a segfault when a numeric value was received for Host:.
81 *) Add a function ap_remove_input_filter. This is to match
82 up with ap_remove_output_filter. [Ryan Bloom]
84 *) Clean up location_walk, so that this step performs a minimum
85 amount of redundant effort (it must be run twice, but it will no
86 longer reparse all <Location > blocks when the request uri
87 hadn't changed.) [William Rowe]
89 *) Eliminate proxy: (and all other 'special') processing from the
90 ap_directory_walk() phase. Modules that want to use special
91 walk logic should refer to the mod_proxy map_to_location example,
92 with it's proxy_walk and proxysection implementation. This makes
93 either directory_walk flavor much more legible, since that phase
94 only runs against real <Directory > blocks.
97 *) Fix a security problem in mod_include which would allow
98 an SSI document to be passed to the client unparsed.
99 [Cliff Woolley, Brian Pane]
101 *) Introduce the map_to_storage hook, which allows modules to bypass
102 the directory_walk and file_walk for non-file requests. TRACE
103 shortcut moved to http_protocol.c as APR_HOOK_MIDDLE, and the
104 directory_walk/file_walk happen as APR_HOOK_VERY_LAST in core.c.
107 *) Add the ability for mod_include to add the INCLUDES filter
108 if the file is configured for the server-parsed handler.
109 This makes the configuration for .shtml files much easier
110 to understand, and allows mod_include to honor Apache 1.3
111 config files. Based on Doug MacEachern's patch to PHP
112 to do the same thing. [Ryan Bloom]
114 *) force OpenSSL to ignore process local-caching and to always
115 get/set/delete sessions using mod_ssl's callbacks
116 [Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>,
117 Geoff Thorpe <geoff@geoffthorpe.net>]
119 *) Make the worker MPM shutdown and restart cleanly. This also
120 cleans up some race conditions, and gets the worker using
121 pools more cleanly. [Aaron Bannert <aaron@clove.org>]
123 *) Implement CRYPTO_set_locking_callback() in terms of apr_lock
125 [Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>]
127 *) Fix for mod_include. Ryan's patch to check error
128 codes put a return in the wrong place. Also, the
129 include handler return code wasn't being checked.
130 I don't like macros with returns, so I converted
131 SPLIT_AND_PASS_PRETAG_BUCKETS into a function.
132 [Paul J. Reder <rederpj@raleigh.ibm.com>]
134 *) fix segv in mod_mime if no AddTypes are configured
135 [John Sterling <sterling@covalent.net>]
137 *) Enable ssl client authentication at SSL_accept time
138 [Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>]
140 *) Fix a segfault in mod_include when the original request has no
141 associated filename (e.g., we're filtering the error document for
142 a bad URI). [Jeff Trawick]
144 *) Fix a storage leak (a strdup() call) in mod_mime_magic. [Jeff Trawick]
146 *) The prefork and OS/2 MPMs are overwriting the pid file when a second copy
147 of httpd is started and shuts down due to socket conflict. Moving the
148 call to ap_log_pid solves the problem.
150 *) Changed the late-1.3 log_config substitution %c to %X, to log the
151 status of the closed connection, as it conflicts with the far more
152 common, historical ssl logging directive %...{var}c. [William Rowe]
154 *) Added the common error/ tree to the build/install targets
155 (similar to the common icons/ tree) for the multi-language error
156 messages that Lars committed earlier. [William Rowe]
158 *) Added a multi process, multi threaded OS/2 MPM mpmt_os2. [Brian Havard]
160 *) Added a default commented-out mod_ldap and mod_auth_ldap
161 configuration to httpd-std.conf and httpd-win.conf
164 *) Added documentation for mod_ldap and mod_auth_ldap.
167 *) Enabled negative caching on attribute comparisons in the LDAP cache.
168 Fixed a problem where the default cache TTL was set in milliseconds
169 not microseconds causing the cache to time out almost immediately.
172 *) Fixed all the #if APR_HAS_SHARED_MEMORY checks within the LDAP
173 module code to follow APR. [Graham Leggett]
175 *) Fixed LDAP cleanup on graceful restarts. LDAP connections are now
176 cleaned up when the connection pool pool is cleaned up.
179 *) Fix a minor issue with Jeff Trawick's mod_include
180 patch. Without this patch, the code will just allocate
181 more bytes in get_combined_directive than are needed.
184 *) Added the LDAP authentication module mod_auth_ldap.
185 [Dave Carrigan <dave@rudedog.org>, Graham Leggett]
187 *) Added the LDAP cache and connection pooling module mod_ldap.
188 [Dave Carrigan <dave@rudedog.org>, Graham Leggett]
190 *) Fix --enable-modules=all breakage with mod_auth_db and mod_auth_digest
191 by allowing a module to disable itself if its prerequisites are not
192 met. [Justin Erenkrantz]
194 Changes with Apache 2.0.24
196 *) Fix a couple of issues in mod_include when the tag appeared at
197 offsets near 8192 in the file being parsed. [Jeff Trawick]
199 *) Fix an assertion failure in mod_ssl when the keepalive timeout is
200 reached. [Jeff Trawick]
202 *) Numerous improvements to the Win32 build system. Introduced command line
203 builds without requiring .mak files for MSVC 6.0 and later versions.
204 Improved .dsp file compatibility for both Visual Studio 5.0 and 6.0 users.
207 *) Assorted corrections and improvements to the winnt_mpm startup code. Better
208 reporting of uninstalled services and other error conditions, and changed the
209 default service name to Apache2. [William Rowe]
211 *) Numerous improvements to the Win32 ApacheMonitor utility, including winnt_mpm
212 compatibility with existing Apache 1.3 Win32 Apache management utilites.
213 [Mladen Turk <mturk@mappingsoft.com>, William Rowe]
215 *) Fixed the segfaults in mod_mime introduced by hash tables in 2.0.20.
216 [William Rowe, Greg Ames]
218 *) Rounded out the mod_mime Add/Remove pairs by adding RemoveLanguage
219 and RemoveCharset directives. [William Rowe]
221 *) The Unix MPMs other than perchild now allow child server
222 processes to use the accept mutex when starting as root and
223 using SysV sems for the accept mutex. Previously, this
224 combination would lead to fatal errors in the child server
225 processes. perchild can't use SysV sems because of security
226 issues. [Jeff Trawick, Greg Ames]
228 *) Added Win32 revision stamp resources to all http binaries
229 (including modules/ and support/ tools.) PR7322 [William Rowe]
231 *) Fix ap_rvprintf to support more than 4K of data at one time.
232 [Cody Sherr <csherr@covalent.net>]
234 *) We have always used the obsolete/deprecated Netscape syntax
235 for our tracking cookies; now the CookieStyle directive
236 allows the Webmaster to choose the Netscape, RFC2109, or
237 RFC2965 format. The new CookieDomain directive allows the
238 setting of the cookie's Domain= attribute, too. PR #s 5006,
239 5023, 5920, 6140 [Ken Coar]
241 *) Tweak server/Makefile so that the rules for generating exports.c
242 are compatible with make utilities which don't expand wildcards
243 in a dependency list (e.g., OS/390 make, certain levels of GNU
244 make). [Jeff Trawick]
246 *) Install the SSL headers. [John Sterling <sterling@covalent.net>]
248 *) Begin to sanitize the MPM configuration directives. Now, all
249 MPMs use the same functions for all common MPM directives. This
250 should make it easier to catch all bugs in these directives once.
251 [Cody Sherr <csherr@covalent.net>]
253 *) Close a major resource leak. Every time we had issued a
254 graceful restart, we leaked a socket descriptor.
257 *) Fix a problem with the new method code. We need to cast
258 the 1 to an apr_int64_t or it will be treated as a 32-bit
259 integer, and it will wrap after being shifted 32 times.
260 [Cody Sherr <csherr@covalent.net> and Ryan Morgan <rmorgan@covalent.net>]
262 *) Fix a bug in mod_expires. Previous to this patch, if you
263 told mod_expires to add 604800 seconds to the last-modified
264 time, it actually added 604800 usec's to the last-modified time,
265 so that when looking at the response it looked like nothing
266 had been done. The root of the problem was that we always compute
267 time in usec's, but we ask users to input sec's. This means we
268 need to convert to usec's before using those values.
271 *) The worker MPM now handles shutdown and restart requests. It
272 definitely isn't perfect, but we do stop the servers correctly.
273 The biggest problem right now is that SIGHUP causes the server to
274 just die. [Ryan Bloom]
276 Changes with Apache 2.0.23
278 *) Use the prefork MPM by default on Unix. [various]
280 *) Added a systray icon monitor application for Win32.
281 [Mladen Turk <mturk@mappingsoft.com>]
283 *) mod_rewrite: Fix the line ending on some non-Unix systems for
284 messages written to the rewrite log.
285 [Richard Labennett <rlabenn@us.ibm.com>]
287 *) All mod_autoindex query parsing is now quietly quashed with the
288 IndexOption IgnoreClient. The IndexOption SuppressColumnSorting
289 still drops the column sort <a href>'s for the column headers, but
290 IgnoreClient is required to ignore these Query options entirely.
293 *) Introduced new mod_autoindex query argument parsing for F=[0|1|2]
294 to allow the client to select plain, FancyIndexing or HTMLTable
295 formatting, V=[0|1] to inhibit or enable version sorting, and
296 P=pattern to return only specific files. The old Query Arguments
297 were reorganized as C=f for sorting column 'f' (same N, D, S, or M
298 as before), and O=A|D for ordering ascending or descending.
301 *) Fixed an error in mod_include's directive parsing routines which
302 caused #if, #elif, and #else expressions containing backslashes
303 to be improperly evaluated. [Cliff Woolley]
305 *) Introduced new mod_autoindex IndexOptions flags: SuppressIcon to
306 drop the icon column, SuppressRules to drop the <hr> elements,
307 and HTMLTable to create rudimentary HTML table listings (implies
308 FancyIndexing). [William Rowe]
310 *) Re-introduced the mod_autoindex IndexOptions flag TrackModified
311 from Apache 1.3.15. This is needed for two reasons, first, given
312 multiple machines within a server farm, ETags and Last-Modified
313 stamps won't correspond from machine to machine, and second, many
314 Unixes don't capture changes to the date or time stamp of existing
315 files, since these don't modify the dirent itself. [William Rowe]
317 *) Re-introduced the mod_autoindex IndexOptions flag FoldersFirst
318 and DirectoryWidth options from Apache 1.3.10.
319 [William Rowe, Ken Coar]
321 *) Eliminated FancyIndexing directive, deprecated early in Apache
322 1.3 by the IndexOptions FancyIndexing syntax. [William Rowe]
324 *) mod_autoindex now excludes any file names that would result in
325 an error, other than a success or redirect. Also optimized
326 the parent directory, always included except in the URI '/'.
329 *) Refactored mod_negotiation and mod_mime to help mod_dir accept
330 negotiated index pages, and prevent the server from defaulting
331 to an autoindex of the directory. mod_negotiation will now die
332 with a 500 Internal Error if it could match some filenames
333 (e.g. for mod_dir) but none can be served. mod_negotation now
334 refuses to serve any file with an extention that mod_mime doesn't
335 recognize, and wasn't part of the request. [William Rowe]
337 *) Eliminate mod_cgi's handling of .exe files without the .exe file
338 extension. This is already handled by multiviews, if the admin
339 wishes to AddHandler .exe or define a content type handler and
340 associate .exe files with that content type. Multiviews must be
341 enabled to allow these to be served. [William Rowe]
343 *) Speed up the server's response to a spike in incoming workload
344 or restarts by assigning empty scoreboard slots to new processes
345 when they are available. [Greg Ames]
347 *) Add a handler to mod_includes.c. This handler is designed to
348 implement the XbitHack directive. This can't be done with a
349 fixup, because we need to check the content-type, which is
350 only available in the handler phase. [Ryan Bloom]
352 *) Make the includes filter check return codes from filters lower in
353 the filter chain. If a lower level filter returns an error, then
354 the request needs to stop immediately. This allows mod_include to
355 stop parsing data once a lower filter recognizes an error.
358 *) Add the ability to extend the methods that Apache understands
359 and have those methods <limit>able in the httpd.conf. It uses
360 the same bit mask/shifted offset as the original HTTP methods
361 such as M_GET or M_POST, but expands the total bits from an int to
362 an ap_int64_t to handle more bits for new request methods than
363 an int provides. [Cody Sherr <csherr@covalent.net>]
365 *) Fix broken mod_mime behavior in merging its arguments. Possible
366 cause of unexplicable crashes introduced in 2.0.20. [William Rowe]
368 *) Solve many mod_ssl porting issues (too many to detail) with
369 help from the whole team, but most notably [Ralf S. Engelschall,
370 Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>,
371 Doug MacEachern, William Rowe, Cliff Woolley]
373 *) More stall fixes for the threaded & worker mpm's.
374 Make mod_status output more accurate. Don't
375 count workers in processes which aren't actively
376 serving requests. [Greg Ames]
378 *) Win32: Get SSI exec cgi tag working. [Bill Stoddard]
380 *) Add a single listener/multiple worker MPM. This MPM is
381 definately not fully correct, but it allows us to solve many
382 of the problems that exist in the threaded MPM. This is a
383 modified version of the threaded MPM. [Ryan Bloom]
385 *) Improve content generation throughout Apache, providing closer
386 compliance with HTML 3.2, HTML 4.01 Transitional and XHTML 1.0
387 Transitional specifications. [William Rowe]
389 Changes with Apache 2.0.22
391 *) Fix a problem where the threaded MPM stalls after restarts or
392 segfaults. Also prevent multiple active processes from using
393 the same scoreboard slot. [Greg Ames]
395 *) Apache/Win32 now fills in the service description with Apache's
396 server version string, including loaded and advertised modules.
399 *) Improved support for the Win32 build, to recover gracefully from
400 missing apr or apr-util directories or the awk interpreter,
401 create the proper cgi-bin examples, including a test-cgi.bat, and
402 fix the perl shebang line for printenv.pl, when installing from
403 the build environment. [William Rowe]
405 *) Fix a segfault in threaded.c caused by passing uninitialized
406 apr_thread_t * to apr_thread_join(). [Jeff Trawick]
408 *) Use new APR number conversion functions to reduce CPU consumption
409 when setting the content length, and in mod_log_config.
412 *) Fix problem reported by Taketo Kabe <kabe@sra-tohoku.co.jp>
413 where HEAD response headers were being repeated twice for
414 files greater than 32K bytes (4*AP_MIN_BYTES_TO_WRITE). This
415 problem in the http_header filter was exposed by the recent rewrite
416 of the content_length filter. [Taketo Kabe, Bill Stoddard]
418 *) Fix seg faults in mod_status with ExtendedStatus enabled, after
419 restarts. A garbage pointer to a vhost's server_rec from the
420 previous generation was being left around under certain
421 conditions. [Greg Ames]
423 *) Fix a cosmetic problem with mod_include. Non-existant SSI vars
424 used to appear as '(none', without the closing paren.
425 [Günter Knauf <eflash@gmx.net>]
427 *) Improve the exports generating awk script. In the past, we had
428 work around problems in the awk script by avoiding some #if and
429 #ifdefs. This has bitten us many times in generating the exports.c
430 file. This improvement allows corrects the header file parsing.
431 [Sander Striker <striker@apache.org>]
433 Changes with Apache 2.0.21
435 *) Resolve the Win32 htpasswd bug, where a file that existed would be
436 overwritten, regardless of the -c flag.
437 [William Rowe, Mladen Turk <mladen.turk@mail.inet.hr>]
439 *) Introduce connection sub-pools into ab. Truncating the lifetime
440 of these allocations means that ab no longer perpetually grows
441 its working set, running out of memory on large request attempts.
444 *) Make scoreboard creation a hook. This allows management
445 modules to have access to the scoreboard at the time that it is
446 created, and at every restart request.
447 [Cody Sherr <csherr@covalent.net>]
449 *) Changed AP_MPMQ_MAX_DAEMONS to refer to MaxClients and
450 added an AP_MPMQ_MAX_DAEMON_USED to refer to the highest
451 daemon index actually used in the scoreboard. I also
452 updated the pertinent calls. [Paul J. Reder]
454 *) Win32: Prevent listening sockets from being inherited by
455 the Apache child process, CGI scripts, rotatelog process
456 etc. If the Apache child process segfaults, any processes
457 that the child started are not reaped. Prior to this fix,
458 these processes inherited the listening sockets which sometimes
459 prevented the restarted Apache child process from accepting
460 connections (ie, the server would hang).
463 *) Provide vhost and request strings when ExtendedStatus is on.
466 *) Fix some issues with the pod and prefork: check the pod *after*
467 processing a connection so that a server processing a time-
468 consuming request bails out as soon as practical; when the
469 parent process wakes up a server process via connect(), use an
470 APR timeout on the connect() so that we don't hang for a long
471 time if there aren't server processes around to do accept().
472 [Jeff Trawick, Greg Ames]
474 *) Performance improvement to mod_mime.c. find_ct() in mod_mime,
475 spends a lot of time in apr_table_get calls. Using the default
476 httpd.conf, the tables for languages and charsets are somewhat
477 large, so the time spent scanning them on each request is
478 significant. Replacing the tables with hash tables provides
479 a nice speedup. [Brian Pane <bpane@pacbell.net>]
481 *) Add two functions to allow modules to access random parts of the
482 scoreboard. This allows modules compiled for one MPM to access the
483 scoreboard, even if it the server was compiled for another MPM.
484 [Harrie Hazewinkel <harrie@covalent.net>]
486 Changes with Apache 2.0.20
488 *) Fix problem in content-length filter where the filter would
489 buffer all the output from a CGI before sending any bytes
490 down the filter stack to the network. This problem would cause
491 significant memory consumption if the CGIs generated
492 lots of bytes. [Bill Stoddard]
494 *) Get non-blocking CGI pipe reads working with the bucket brigades.
497 *) Fix seg fault on Windows when serving files cached with mod_file_cache.
500 *) Fix a bug in the threaded MPM that would cause it to kill off all
501 workers immediately after starting if the number of workers started
502 was above a certain threshold. [Ryan Bloom, Bill Stoddard]
504 Changes with Apache 2.0.19
506 *) Fix problem with threaded MPM. The problem was that if each child
507 process was busy serving a single long-lived request and the server
508 was sent a graceful restart signal, the server would stop serving
509 requests. This would happen because each child process would wait to
510 die until the last thread was done, and the parent wouldn't spawn any
511 new children until a process died. Now, the parent looks at the fact
512 that the children are dying gracefully, and starts new children.
513 Those new children only start enough threads to compliment the number
514 of threads in the other child process that shares the same spot in
515 the scoreboard. In this way, we make sure to never go over
516 MaxClients. [Ryan Bloom]
518 *) modified mod_negotiation and mod_autoindex to speed up by almost a
519 factor of two on apr_dir_read()-enhanced platforms, such as Win32
520 and OS2, by calling ap_sub_request_lookup_dirent() with the results
521 already provided by apr_dir_read(). [William Rowe]
523 *) mod_file_cache is now more robust to filtering and serves requests
524 slightly more efficiently. [Cliff Woolley]
526 *) Fix problem handling FLUSH bucket in the chunked encoding filter.
527 Module was calling ap_rwrite() followed by ap_rflush() but the
528 served content was not being displayed in the browser. Inspection
529 of the output stream revealed that the first data chunk was
530 missing the trailing CRLF required by the RFC. [Bill Stoddard]
532 *) apxs no longer generates ap_send_http_header() in the example handler
534 *) Fix an ab problem which could cause a divide-by-zero exception
535 with certain invocations (e.g., ab -k -c 6 -n 100 localhost/).
536 [Ian Holsman <ianh@cnet.com>]
538 *) Solve case-insensitive platforms' confusion about negotiated
539 filenames, allowing files of differnt case to match in choosing
540 the document to serve. [William Rowe]
542 *) Fix brokenness when ThreadsPerChild is higher than the built-in
543 limit. We left ap_threads_per_child at the higher value which
544 led to segfaults when doing certain scoreboard operations.
547 *) Fix seg faults and/or missing output from mod_include. The
548 default_handler was using the subrequest pool for files and
549 MMAPs, even though the associated APR structures typically
550 live longer than the subrequest. [Greg Ames]
552 *) Extend mod_setenvif to support specifying regular expressions
553 on the SetEnvIf (and SetEnvIfNoCase) directive attribute field.
554 Example: SetEnvIf ^TS* [a-z].* HAVE_TS
555 will cause HAVE_TS to be set if any of the request headers begins
556 with "TS" and has a value that begins with any character in the
557 set [a-z]. [Bill Stoddard]
559 *) httpd children now re-bind themselves to a random CPU on
560 multiprocessor systems on AIX via bindprocessor() in 2.0.
561 [Victor J. Orlikowski]
563 *) Fix htdigest. It would go into a loop in getline when adding
564 a second user. [Bill Stoddard]
566 *) Win32 platforms now fully support mod_userdir options. [Will Rowe]
568 *) Automatically generate httpd.exp for AIX.
569 DSOs now work again on AIX in 2.0
570 [Victor J. Orlikowski]
572 *) Add a new request hook, error_log. This phase allows modules
573 to act on the error log string _after_ it has been written
574 to the error log. The goal for this hook is to allow monitoring
575 modules to send the error string to the monitoring agent.
578 *) Modify mod_echo to make it use filters for input and output.
579 [Ryan Morgan <rmorgan@covalent.net>]
581 *) Extend mod_headers to support conditional driven Header
582 add, append and set. Use SetEnvIf to set an envar and conditionally
583 add/append/set headers based on this envar thusly:
585 SetEnvIf TSMyHeader value HAVE_TSMyHeader
586 Header add MyHeader "%t %D" env=HAVE_TSMyHeader
588 If the request contains header "TSMyHeader: value" then header
589 MyHeader: "t=xxxxxxxxxx D=yyyy" will be sent on the response.
592 *) Extend mod_headers to support using format specifiers on Header
593 add, append and set header values. Two format specifiers are supported:
595 %t - reports, in UTC microseconds since the epoch, when the
596 request was received.
598 %D - reports the time, in microseconds, between when the request was
599 received and the response sent.
602 Header add MyHeader "This request served in %D microseconds. %t"
604 results in a header being added to the response that looks like this:
606 MyHeader: This request served in D=5438 microseconds. t=991424704447256
610 *) Fix reset_filter(). We need to be careful how we remove filters.
611 If we set r->output_filters to NULL, we also have to reset the
612 connection's filters. [John Sterling]
614 *) Optimise reset_filter() in http_protocol.c. [Greg Stein]
616 *) Add a check to ap_die() to make sure the filter stack is sane and
617 contains the correct basic filters when an error occurs. This fixes
618 a problem where headers are not being sent on error. [John Sterling]
620 *) New Header directive 'echo' option. "Header echo regex" will
621 cause any headers received on the request that match regex to be
622 echoed to (included in) the response headers.
625 *) include/ap_compat.h tested and set APR_COMPAT_H instead of AP_COMPAT_H.
626 This prevented the inclusion of apr_compat.h. PR #7773
627 [Oleg Broytmann <phd@phd.pp.ru>]
629 *) Moved util_uri to the apr-util library. This required a bunch of
630 apr_name changes for the uri utility functions. [Justin Erenkrantz]
632 *) Move the addition of default AP_HTTP_HTTP_HEADER filters to the
633 insert_filter phase so that other filters are not bypassed by default.
636 *) Reimplement mod_headers as an output filter. mod_headers can now
637 add custom headers to inbound requests using the RequestHeader directive
638 and to responses using the same old Header directive. [Graham Leggett]
640 Changes with Apache 2.0.18
642 *) Fix command-line processing so that if a bad argument is specified
643 Apache will exit. [Jeff Trawick]
645 *) Change the make targets and rules to be consistent in all of the
646 Apache-owned source trees. [Roy Fielding]
648 *) Fix processing of the TRACE method. Previously we passed bogus
649 parms to form_header_field() and it overlaid some vhost structures,
650 resulting in a segfault in check_hostalias().
651 [Greg Ames, Jeff Trawick]
653 *) Win32: Add support for reliable piped logs. If the logging process
654 goes down, Apache will automatically restart it. This function has
655 been part of Apache on Unix/Linux/BSD since the early v1.3 releases.
658 *) Do not start piped log processes during the config file
659 preflight. This change also circumvents a problem on
660 Windows where the rotatelog processes created during preflight
661 was not getting cleaned up properly.
664 *) add "Request Phase Participation" info to mod_info
667 *) Make first phase changes to the scoreboard data structures in
668 preparation for the rewriting of the scoreboard per my posted
669 design notes. [Paul J. Reder]
671 *) Fix httpd's definition of LTFLAGS to be consistent with that of apr
672 and apr-util, allow it to be overridden by the configure command-line
673 (default="--silent") and introduce LT_LDFLAGS to replace what we were
674 formerly abusing as LTFLAGS. [Roy Fielding]
676 *) Clean up the reporting of incorrect closing container tags.
677 [Barrie Slaymaker <barries@slaysys.com>]
679 *) Simplify the configure process by moving all libtool stuff to APR
680 and moving hints.m4 inline. [Roy Fielding]
682 *) Add the AP_DECLARE()/AP_CORE_DECLARE macros on the return types
683 of functions used by mod_proxy for export in the DLL
684 [Ian Holsman <IanH@cnet.com>]
686 *) Prevent a hang when a cgi handled by mod_cgid tries to read a
687 request body from its stdin but no reqest body is being written to
688 the cgi. [Jeff Trawick]
690 *) mod_log_config: %c connection status incorrectly logged
691 as "-" (non-keepalive) when MaxKeepAliveRequests is set to 0.
694 *) Get mod_cern_meta working under Windows
697 *) Create Files, and thus MMAPs, out of the request pool, not the
698 connection pool. This solves a small resource leak that had us
699 not closing files until a connection was closed. In order to do
700 this, at the end of the core_output_filter, we loop through the
701 brigade and convert any data we have into a single HEAP bucket
702 that we know will survive clearing the request_rec.
703 [Ryan Bloom, Justin Erenkrantz <jerenkrantz@ebuilt.com>,
706 *) Completely revamp configure so that it preserves the standard make
707 variables CPPFLAGS, CFLAGS, CXXFLAGS, LDFLAGS and LIBS by moving
708 the configure additions to EXTRA_* variables. Also, allow the user
709 to specify NOTEST_* values for all of the above, which eliminates the
710 need for THREAD_CPPFLAGS, THREAD_CFLAGS, and OPTIM. Fix the setting
711 of INCLUDES and EXTRA_INCLUDES. Check flags as they are added to
712 avoid pointless duplications. Fix the order in which flags are given
713 on the compile and link lines. Remove obsolete macros APR_DOEXTRA,
714 AC_ADD_LIBRARY, AC_CHECK_DEFINE, APACHE_PASSTHRU, and APACHE_ONCE.
715 Added APR_SAVE_THE_ENVIRONMENT and APR_RESTORE_THE_ENVIRONMENT macros.
716 Renamed AC_TYPE_RLIM_T macro to APACHE_TYPE_RLIM_T. [Roy Fielding]
718 *) Get mod_tls to compile/work better on Windows. PR #7612
719 [Bernhard Schrenk <b.schrenk@improx.com>]
721 *) Fix shutdown/restart hangs in the threaded MPM.
722 [Jeff Trawick, Greg Ames, Ryan Bloom]
724 *) Removed the keptalive boolean from conn_rec because it is now only
725 used by a single routine and can be replaced by a local variable.
726 [Greg Stein, Ryan Bloom, Roy Fielding]
728 *) Patch prefork to put enough of the signal processing back in so that
729 signals are all handled properly now. The previous patch fixed the
730 deadlock race condition, but broke the user directed signal handling.
731 This fixes it to work the way it did before my previous prefork patch
732 (primarily, SIGTERM is now working).
734 *) Change how input filters decide how much data is returned to the
735 higher filter. We used to use a field in the conn_rec, with this
736 change, we use an argument to ap_get_brigade to determine how much
737 data is retrieved. [Ryan Bloom]
739 *) Fix seg fault at start-up introduced by Ryan's change to enable
740 modules to specify their own logging tags. mod_log_config
741 registers an optional function, ap_register_log_handler().
742 ap_register_log_handler() was being called by http_core before
743 the directive hash table was created. This patch creates the
744 directive hash table before ap_register_log_handler() is
745 registered as an optional function.
746 [jean-frederic clere <jfrederic.clere@fujitsu-siemens.com>]
748 *) Add ap_set_int_slot() function
749 [John K. Sterling <sterling@covalent.net>]
751 *) Under certain circumstances, Apache did not supply the
752 right response headers when requiring authentication.
753 [Gertjan van Wingerde <Gertjan.van.Wingerde@cmg.nl>] PR#7114
754 (This is a port of the change that went into Apache 1.3.19.)
756 *) Allow modules to specify their own logging tags. This basically
757 allows a module to tell mod_log_config that when %x is encountered
758 a specific function should be called. Currently, x can be any single
759 character. It may be more useful to make this a string at some point.
762 Changes with Apache 2.0.17
764 *) If a higher-level filter handles the the byterange aspects of a
765 request, then the byterange filter should not try to redo the
766 work. The most common case of this happening, is a byterange
767 request going through the proxy, and the origin server handles
768 the byterange request. The proxy should ignore it.
769 [Graham Leggett <minfrin@sharp.fm>]
771 *) Changed the threaded mpm to have child_main join to each of the
772 worker threads to make sure the kids are all gone before child_main
773 exits after a signal (cleanup from perform_idle_server_maintenance).
774 This is an extension of Ryans recent commit to make the child_main
777 *) Add more options to the ap_mpm_query function. This also allows MPMs to
778 report if their threads are dynamic or static. Finally, this also
779 implements a new API, ap_show_mpm, which returns the MPM that was
780 required into the core. [Harrie Hazewinkel <harrie@covalent.net>]
782 *) Do not install the binaries from the support directory twice.
783 [jun-ichiro hagino <itojun@iijlab.net>]
785 *) The ap_f* functions should flush data to the filter that is passed
786 in, not the the filter after the one passed in.
787 [Ryan Morgan <rmorgan@covalent.net>]
789 *) Make ab work again by changing its native types to apr types and formats.
790 [Justin Erenkrantz <jerenkrantz@ebuilt.com>]
792 *) Move the byterange filter and all of the supporting functions back
793 to the HTTP module. The byterange filter turned out to be very
794 HTTP specific, and it belongs in the HTTP module. [Greg Stein]
796 *) Make clean, distclean, and extraclean consistently according to the
797 Gnu makefile guidelines. [Justin Erenkrantz <jerenkrantz@ebuilt.com>]
799 *) Fix errors in the renaming of the apr_threadattr_detach_xxx functions.
800 This may have been causing problems stopping processes in the threaded
803 *) Fix content-length in mod_negotiation to a long int representation.
806 *) Remove BindAddress from the default config file.
807 [giles@nemeton.com.au]
809 *) Allow module authors to add a module to their Apache build using
810 --with-module, without re-running buildconf. The syntax is:
811 --with-module=module_type:/path/to/module.c
812 The configure script will copy the module.c file to
813 modules/module_type, and it will be added to the relevant Makefiles.
814 currently, this only works for static modules. [Ryan Bloom]
816 *) Changes required to make prefork clean up idle children properly.
817 There was a window during which a starting worker deadlocks when
818 an idle cleanup arrives before it completes init. Apache then keeps
819 trying to cleanup the same deadlocked worker forever (until higher
820 pids come along, but it still will never reduce below the deadlocked
821 pid). Thus the number of children would not reduce to the correct
822 idle level. [Paul J. Reder]
824 Changes with Apache 2.0.16
826 *) Change the default installation directory to /usr/local/apache2,
827 as now defined by the "Apache" layout in config.layout. [Marc Slemko]
829 *) OS/2: Added support for building loadable modules as OS/2 DLLs.
832 *) Get MaxRequestsPerChild working with the Windows MPM.
835 *) Make generic hooks to work, with mod_generic_hook_import/export
836 experimental modules. [Ben Laurie, Will Rowe]
838 *) Fix segfaults for configuration file syntax errors such as
839 "<Directory>" followed by "</Directory" and
840 "<Directory>" followed by "</Directoryz>". [Jeff Trawick]
842 *) Cleanup the --enable-layout option of configure. This makes
843 us use a consistent location for the config.layout file, and it
844 makes configure more portable.
845 [jun-ichiro hagino <itojun@iijlab.net>]
847 *) Changes to 'ab'; fixed int overrun's, added statistics, output in
848 csv/gnuplot format, rudimentary ssl support and various other tweaks
849 to make results more true to what is measured. The upshot of this it
850 turns out that 'ab' has often underreported the true performance of
851 apache. Often by a order of magnitude :-) See talk/paper of Sander
852 Temme <sctemme@covalent.net> at April ApacheCon 2001 for details.
853 [Dirk-Willem van Gulik]
855 *) Clean up mod_cgid's temporary request pool. Besides fixing a
856 storage leak this ensures that some unnecessary pipes are closed.
859 *) Performance: Add quick_handler hook. This hook is called at the
860 very beginning of the request processing before location_walk,
861 translate_name, etc. This hook is useful for URI keyed content
862 caches like Mike Abbott's Quick Shortcut Cache.
865 *) top_module global variable renamed to ap_top_module [Perl]
867 *) Move ap_set_last_modified to the core. This is a potentially
868 controversial change, because this is kind of HTTP specific. However
869 many protocols should be able to take advantage of this kind of
870 information. I expect that headers will need one more layer of
871 indirection for multi-protocol work, but this is a small step in
872 the right direction. [Ryan Bloom]
874 *) Enable mod_status by default. This matches what Apache 1.3 does.
877 *) Add a ScriptSock directive to the default config file. This is
878 only enabled when mod_cgid is used.
879 [Taketo Kabe <kabe@sra-tohoku.co.jp>]
881 Changes with Apache 2.0.15
883 *) Untangled the buildconf script and eliminated the need for build's
884 aclocal.m4, generated_lists, build.mk, build2.mk, and a host of other
885 libtool muck that is now under srclib/apr/build. [Roy Fielding]
887 *) Win32: Don't accept more connections than we have worker threads
891 *) Fix bug in the Unix threaded.c MPM that allowed child processes
892 to fork() new child processes.
895 *) Fix a major security problem with double-reverse lookup checking.
896 Previously, a client connecting over IPv4 would not be matched
897 properly when the server had an IPv6 listening socket. PR #7407
898 [Taketo Kabe <kiabe@sra-tohoku.co.jp>]
900 *) Change the way the beos MPM handles polling to allow it to stop and
901 restart. Problem was the sockets being polled were being reset by
902 the select call, so once it had accepted a connection it was no
903 longer listening on the UDP socket we use for shutdown instructions.
904 APR needs to be altered, patch on it's way. [David Reid]
906 *) Empty out the brigade shared by ap_getline()/ap_get_client_block()
907 on error exit from ap_getline(). Some other code got upset because
908 the wrong data was in the brigade. [Greg Ames, Jeff Trawick]
910 *) Handle ap_discard_request_body() being called more than once.
911 [Greg Ames, Jeff Trawick]
913 *) Get rid of an inadvertent close of file descriptor 2 in
914 mod_mime_magic. [Greg Ames, Jeff Trawick]
916 *) Add a hook, create_request. This hook allows modules to modify
917 a request while it is being created. This hook is called for all
918 request_rec's, main request, sub request, and internal redirect.
919 When this hook is called, the the r->main, r->prev, r->next
920 pointers have been set, so modules can determine what kind of
921 request this is. [Ryan Bloom]
923 *) Cleanup the build process a bit more. The Apache configure
924 script no longer creates its own helper scripts, it just
926 [jean-frederic clere <jfrederic.clere@fujitsu-siemens.com>]
928 *) Stop the forced downgrade of the connection to HTTP/1.0 for
929 proxy requests. [Graham Leggett]
931 *) Avoid using sscanf to determine the HTTP protocol number in
932 the common case because sscanf is a performance hog. From
933 Mike Abbot's Accelerating Apache patch number 6.
934 [Mike Abbot <mja@trudge.engr.sgi.com>, Bill Stoddard]
936 *) Fix a security exposure in mod_access. Previously when IPv6
937 listening sockets were used, allow/deny-from-IPv4-address rules
938 were not evaluated properly (PR #7407). Also, add the ability to
939 specify IPv6 address strings with optional prefix length on Allow
940 and Deny. [Jeff Trawick]
942 *) Enhance rotatelogs so that a UTC offset can be specified, and
943 the logfile name can be formatted using strftime(3). (Brought
944 forward from 1.3.) [Ken Coar]
946 *) Reimplement the Windows MPM (mpm_winnt.c) to eliminate calling
947 DuplicateHandle on an IOCompletionPort (a practice which
948 MS "discourages"). The new model does not rely on associating
949 the completion port with the listening sockets, thus the
950 completion port can be completely managed within the child
951 process. A dedicated thread accepts connections off the network,
952 then calls PostQueuedCompletionStatus() to wake up worker
953 threads blocked on the completion port.
956 *) Bring forward the --suexec-umask option which allows the
957 builder to preset the umask for suexec processes. [Ken Coar]
959 *) Add a -V flag to suexec, which causes it to display the
960 compile-time settings with which it was built. (Only
961 usable by root or the AP_HTTPD_USER username.) [Ken Coar]
963 *) Mod_include should always unset the content-length if the file is
964 going to be passed through send_parsed_content. There is no to
965 determine if the content will change before actually scanning the
966 entire content. It is far safer to just remove the C-L as long
967 as we are scanning it. [Ryan Bloom]
969 *) Make sure Apache sends WWW-Authenticate during a reverse proxy
970 request and not Proxy-Authenticate.
971 [Graham Leggett <minfrin@sharp.fm>]
973 Changes with Apache 2.0.14
975 *) Fix content-length computation. We ONLY compute a content-length if
976 We are not in a 1.1 request and we cannot chunk, and this is a keepalive
977 or we already have all the data. [Ryan Bloom]
979 *) Report unbounded containers in the config file. Previously, a typo
980 in the </container> directive could result in the rest of the config
981 file being silently ignored, with undesired defaults used.
984 *) Make the old_write filter use the ap_f* functions for the buffering.
987 *) Move more code from the http module into the core server. This
988 is core code, basically the default handler, the default input
989 and output filters, and all of the core configuration directives.
990 All of this code is required in order for the server to work, with or
991 without HTTP. The server is closer to working without the HTTP
992 module, although there is still more to do. [Ryan Bloom]
994 *) Fix a number of SGI compile warnings throughout the server. Fix some
995 bad parameters to apr_bucket_read(). Fix a bad statement in
996 ap_method_in_list(). For the mod_rewrite cache use apr_time_t
997 consistently; we were mixing apr_time_t and time_t in invalid ways
998 before. In load_file(), call apr_dso_error() instead of
999 apr_strerror() so that we get a more specific string on some platforms.
1000 PR #6980 [Jeff Trawick]
1002 *) Allow modules to query the MPM about it's execution profile. This
1003 query API can and should be extended in the future, but for now,
1004 max_daemons, and threading or forking is a very good start.
1005 [Jon Travis <jtravis@covalent.net>]
1007 *) Modify mod_include to send blocks of data no larger than 9k.
1008 Without this, mod_include will wait until the whole file is parsed,
1009 or the first tag is found to send any data to the client.
1010 [Paul J. Reder <rederpj@raleigh.ibm.com>]
1012 *) Fix mod_info, so that <Directory> and <Location> directives are
1013 not displayed twice when displaying the current configuration.
1014 [Ryan Morgan <rmorgan@covalent.net>]
1016 *) Add config directives to override DEFAULT_ERROR_MSG and
1017 DEFAULT_TIME_FORMAT. This was sent in as PR 6193.
1018 [Dan Rench <drench@xnet.com>]
1020 *) Get mod_info building and loading on Win32. [William Rowe]
1022 *) Begin to move protocol independant functions out of mod_http. The goal
1023 is to have only functions that are HTTP specific in the http directory.
1026 Changes with Apache 2.0.13
1028 *) Don't assume that there will always be multiple calls to the byterange
1029 filter. It is possible that we will need to do byteranges with only
1030 one call to the filter. [Ryan Morgan <rmorgan@covalent.net>]
1032 *) Move the error_bucket definition from the http module to the
1033 core server. Every protocol will need this ability, not just
1036 Changes with Apache 2.0.12
1038 *) Modify mod_file_cache to save pre-formatted strings for
1039 content-length and last-modified headers for performance.
1040 [Mike Abbot <mja@trudge.engr.sgi.com>]
1042 *) Namespace protect IOBUFSIZ since it is exposed in the API.
1043 [Jon Travis <jtravis@covalent.net>]
1045 *) Use "Basic" authentication instead of "basic" in ab, as the spec
1046 says we should. [Andre Breiler <andre.breiler@rd.bbc.co.uk>]
1048 *) Fix a seg fault in mod_userdir.c. We used to use the pw structure
1049 without ever filling it out. This fixes PR 7271.
1050 [Taketo Kabe <kabe@sra-tohoku.co.jp> and
1051 Cliff Woolley <cliffwoolley@yahoo.com>]
1053 *) Add a couple of GCC attribute tags to printf style functions.
1054 [Jon Travis <jtravis@covalent.net>]
1056 *) Add the correct language tag for interoperation with the Taiwanese
1057 versions of MSIE and Netscape. [Clive Lin <clive@CirX.ORG>] PR#7142
1059 *) Migrate the perchild MPM to use the new apr signal child, and
1060 APR thread functions. [Ryan Bloom]
1062 *) Close one copy of the CGI's stdout before creating the new process.
1063 The CGI will still have stdout, because we have already dup'ed it.
1064 This keeps Apache from waiting forever to send the results of a CGI
1065 process that has forked a long-lived child process.
1066 [Taketo Kabe <kabe@sra-tohoku.co.jp>]
1068 *) Remove the rest of the pthreads functions from the threaded MPM.
1069 This requires the APR support for a signal thread that was just
1072 *) Make mod_dir use a fixup for sending a redirect to the browser.
1073 Before this, we were using a handler, which doesn't make much
1074 sense, because the handler wasn't generating any data, it would
1075 either return a redirect error code, or DECLINED. This fits the
1076 current hooks better. [Ryan Morgan <rmorgan@covalent.net>]
1078 *) Make the threaded MPM use APR threads instead of pthreads.
1081 *) Get mod_tls to the point where it actually appears to work in all cases.
1084 *) implement --enable-modules and --enable-mods-shared for "all" and
1085 "most". [Greg Stein]
1087 *) Move the threaded MPM to use APR locks instead of pthread locks.
1090 *) Rename mpmt_pthread to threaded. This is more in line with the
1091 fact that mpmt_pthread shouldn't be using pthreads directly, and
1092 it is a smaller name that doesn't tie into anything.
1095 *) Rename the module structures so that the exported symbol matches
1096 the file name, and it is easier to automate the installation
1097 process (generating LoadModule directives from the module filenames).
1100 *) Remove the coalesce filter. With the ap_f* functions, this filter
1101 is no longer needed. [Ryan Bloom]
1103 Changes with Apache 2.0.11
1105 *) Remove the dexter MPM. Perchild is the same basic idea, but it has the
1106 added feature of allowing a uid/gid per child process. If no
1107 uid/gid is specified, then Perchild behaves exactly like dexter.
1110 *) Get perchild building again. [Ryan Bloom]
1112 *) Don't disable threads just because we are using the prefork MPM.
1113 If somebody wants to compile without threads, they must now add
1114 --disable-threads to the configure command line. [Ryan Bloom]
1116 *) Begin to move the calls to update_child_status into common code, so
1117 that each individual MPM does not need to update the scoreboard itself.
1120 *) Allow mod_tls to compile under Unix boxes where openssl has been
1121 installed to the system include files.
1122 [Gomez Henri <new-httpd@slib.fr>]
1124 *) Cleanup the mod_tls configure process. This should remove any need
1125 to hand-edit any files. We require OpenSSL 0.9.6 or later, but
1126 configure doesn't check that yet. [Ryan Bloom]
1128 *) Add a very early prototype of SSL support (in mod_tls.c). It is
1129 vital that you read modules/tls/README before attempting to build
1132 *) Fix a potential seg fault on all platforms. David Reid fixed this
1133 on BEOS, but the problem could happen anywhere, so we don't want
1134 to #ifdef it. [Cliff Woolley <cliffwoolley@yahoo.com>]
1136 *) Add new LogFormat directive, %D, to log time it takes to serve a
1137 request in microseconds. [Bill Stoddard]
1139 *) Change AddInputFilter and AddOutputFilter to SetInputFilter and
1140 SetOutputFilter. This corresponds nicely with the other Set
1141 directives, which operate on containers while the Add* directives
1142 tend to work directly on extensions. [Ryan Bloom]
1144 *) Cleanup the header handling a bit. This uses the apr_brigade_*
1145 functions for the buffering so that we don't need to compute
1146 the length of the headers before we actually create the header
1147 buffer. [Ryan Bloom]
1149 *) Allow filters to buffer data using the ap_f* functions. These have
1150 become macros that resolve directly to apr_brigade_*.
1153 *) Get the Unix MPM's to do a graceful restart again. If we are going
1154 to register a cleanup with ap_cleanup_scoreboard, then we have to
1155 kill the cleanup with the same function, and that function can't be
1156 static. [Ryan Bloom]
1158 *) Install all required header files. Without these, it was not
1159 possible to compile some modules outside of the server.
1162 *) Fix the AliasMatch directive in Apache 2.0. When we brought a patch
1163 forward from 1.3 to 2.0, we missed a single line, which broke regex
1164 aliases. [Ryan Bloom]
1166 *) We have a poor abstraction in the protocol. This is a temporary
1167 hack to fix the bug, but it will need to be fixed for real. If
1168 we find an error while sending out a custom error response, we back
1169 up to the first non-OK request and send the data. Then, when we send
1170 the EOS from finalize_request_protocol, we go to the last request,
1171 to ensure that we aren't sending an EOS to a request that has already
1172 received one. Because the data is sent on a different request than
1173 the EOS, the error text never gets sent down the filter stack. This
1174 fixes the problem by finding the last request, and sending the data
1175 with that request. [Ryan Bloom]
1177 *) Make the server status page show the correct restart time, and
1178 thus the proper uptime. [Ryan Bloom]
1180 *) Move the CGI creation logic from mod_include to mod_cgi(d). This
1181 should reduce the amount of duplicate code that is required to
1182 create CGI processes.
1183 [Paul J. Reder <rederpj@raleigh.ibm.com>]
1185 *) ap_new_connection() closes the socket and returns NULL if a socket
1186 call fails. Usually this is due to a connection which has been
1187 reset. [Jeff Trawick]
1189 *) Move the Apache version information out of httpd.h and into release.h.
1190 This is in preparation for the first tag with the new tag and release
1191 system. [Ryan Bloom]
1193 *) Begin restructuring scoreboard code to enable adding back in
1194 the ability to use IPC other than shared memory.
1195 Get mod_status working on Windows again. [Bill Stoddard]
1197 *) Make mod_status work with 2.0. This will work for prefork,
1198 mpmt_pthread, and dexter. [Ryan Bloom]
1200 *) Correct a typo in httpd.conf.
1201 [Kunihiro Tanaka <tanaka@apache.or.jp>] PR#7154
1203 *) Really fix mod_rewrite map lookups this time. [Tony Finch]
1205 *) Get the correct IP address if ServerName isn't set and we can't
1206 find a fully-qualified domain name at startup.
1207 PR#7170 [Danek Duvall <dduvall@eng.sun.com>]
1209 *) Make mod_cgid work with SuExec. [Ryan Bloom]
1211 *) Adopt apr user/group name features for mod_rewrite. Eliminates some
1212 'extra' stat's for user/group since they should never occur, and now
1213 resolves the SCRIPT_USER and SCRIPT_GROUP, including on WinNT NTFS
1214 volumes. [William Rowe]
1216 *) Adopt apr features to simplify mod_includes. This changes the
1217 behavior of the USER_NAME variable, unknown uid's are now reported
1218 as USER_NAME="<unknown>" rather than the old user#000 result.
1219 WinNT now resolves USER_NAME on NTFS volumes. [William Rowe]
1221 *) Adopt apr features for simplifing mod_userdir, and accept the new
1222 Win32/OS2 exceptions without hiccuping. [William Rowe]
1224 *) Replace configure --with-optim option by using and saving the
1225 environment variable OPTIM instead. This is needed because configure
1226 options do not support multiple flags separated by spaces.
1229 *) Fix some byterange handling. If we get a byte range that looks like
1230 "-999999" where that is past the end of the file, we should return
1231 a PARTIAL CONTENT status code, and return the whole file as one big
1232 byterange. This matches the 1.3 handling now. [Ryan Bloom]
1234 *) Make the error bucket a real meta-data bucket. This means that the
1235 bucket length is 0, and a read returns NULL data. If one of these
1236 buckets is passed down after the headers are sent, this data will
1237 just be ignored. [Greg Stein]
1239 *) The prefork MPM wasn't killing child processes correctly if a restart
1240 signal was received while the process was serving a request. The child
1241 process would become the equivalent of a second parent process. If
1242 we break out of the accept loop, then we need to do die after cleaning
1243 up after ourselves. [Ryan Bloom]
1245 *) Change the Prefork MPM to use SIGWINCH instead of SIGUSR1 for graceful
1246 restarts. [Ryan Bloom]
1248 *) Modify the apr_stat/lstat/getfileinfo calls within apache to use
1249 the most optimal APR_FINFO_wanted bits. This spares Win32 from
1250 performing very expensive owner, group and permission lookups
1251 and allows the server to function until these apr_finfo_t fields
1252 are implemented under Win32. [William Rowe]
1254 *) Support for typedsafe optional functions - that is functions exported by
1255 optional modules, which, therefore, may or may not be present, depending
1256 on configuration. See the experimental modules mod_optional_fn_{ex,im}port
1257 for sample code. [Ben Laurie]
1259 *) filters can now report an HTTP error to the server. This is done
1260 by sending a brigade where the first bucket is an error_bucket.
1261 This bucket is a simple bucket that stores an HTTP error and
1262 a string. Currently the string is not used, but it may be needed
1263 to output an error log. The http_header_filter will find this
1264 bucket, and output the error text, and then return
1265 AP_FILTER_ERROR, which informs the server that the error web page
1266 has already been sent. [Ryan Bloom]
1268 *) If we get an error, then we should remove all filters except for
1269 those critical to serving a web page. This fixes a bug, where
1270 error pages were going through the byterange filter, even though
1271 that made no sense. [Ryan Bloom]
1273 *) Relax the syntax checking of Host: headers in order to support
1274 iDNS. PR#6635 [Tony Finch]
1276 *) Cleanup the byterange filter to use the apr_brigade_partition
1277 and apr_bucket_copy functions. This removes a lot of very messy
1278 code, and hopefully makes this filter more stable.
1281 *) Remove AddModule and ClearModuleList directives. Both of these
1282 directives were used to ensure that modules could be enabled
1283 in the correct order. That requirement is now gone, because
1284 we use hooks to ensure that modules are in the correct order.
1287 *) When SuExec is specified, we need to add it to the list of
1288 targets to be built. If we don't, then any changes to the
1289 configuration won't affect SuExec, unless 'make suexec' is
1290 specifically run. [Ryan Bloom]
1292 *) Cleaned out open_file from mod_file_cache, as apr now accepts
1293 the APR_XTHREAD argument to open a file for consumption by
1294 parallel threads on win32. [William Rowe]
1296 *) Correct a bug in determining when we follow symlinks. The code
1297 expected a stat -1 result, not an apr_status_t positive error.
1298 Also check if the APR_FINFO_USER fields are valid before we
1299 follow the link. [William Rowe]
1301 *) Move initgroupgs, ap_uname2id and ap_gname2id from util.c to
1302 mpm_common.c. These functions are only valid on some platforms,
1303 so they should not be in the main-line code. [Ryan Bloom]
1305 *) Remove ap_chdir_file(). This function is not thread-safe,
1306 and nobody is currently using it. [Ryan Bloom]
1308 *) Do not try to run make depend if there are no .c files in the
1309 current directory, doing so makes `make depend` fail.
1312 *) Update highperformance.conf to work with either prefork or
1313 pthreads mpms. [Greg Ames]
1315 *) Stop checking to see if this is a pipelined request if we know
1316 for a fact that it isn't. Basically, if r->connection->keepalive == 0.
1317 This keeps us from making an extra read call when serving a 1.0
1318 request. [Ryan Bloom and Greg Stein]
1320 *) Fix the handling of variable expansion look-ahead in mod_rewrite,
1321 i.e. syntax like %{LA-U:REMOTE_USER}, and also fix the parsing of
1322 more complicated nested RewriteMap lookups. PR#7087 [Tony Finch]
1324 *) Fix the RFC number mentioned when complaining about a missing
1325 Host: header. PR#7079 [Alexey Toptygin <alexeyt@wam.umd.edu>]
1327 *) Fix an endless loop in ab which occurred when ab was posting
1328 and the server dropped the connection unexpectedly.
1331 *) Fix a segfault while handling request bodies in ap_http_filter().
1332 This problem has been seen with mod_dav usage as well as with
1333 requests where the body was just being discarded. [Jeff Trawick]
1335 *) Some adjustment on the handling and automatic setting (via
1336 hints.m4) of various compilation flags (eg: CFLAGS). Also,
1337 add the capability to specify flags (NOTEST_CFLAGS and
1338 NOTEST_LDFLAGS) which are used to compile Apache, but
1339 not used during the configuration process. Useful for
1340 flags like "-Werror". [Jim Jagielski]
1342 *) Stop using environment variables to force debug mode or
1343 no detach. We now use the -D command line argument to
1344 specify the correct mode. -DONE_PROCESS and -DNO_DETACH.
1345 [Greg Stein, Ryan Bloom]
1347 *) Change handlers to use hooks. [Ben Laurie]
1349 *) Stop returning copies of filenames from both apr_file_t and
1350 apr_dir_t. We pstrdup the filenames that we store in the
1351 actual structures, so we don't need to pstrdup the strings again.
1354 *) mod_cgi: Fix some problems where the wrong error value was being
1355 traced. [Jeff Trawick]
1357 *) EBCDIC: Fix some missing ASCII conversion on some protocol data.
1360 *) Add generic hooks. [Ben Laurie]
1362 *) Use a real pool to dup the error log descriptor. [Ryan Bloom]
1364 *) Fix a segfault caused by mod_ext_filter when the external filter
1365 program does not exist. [Jeff Trawick]
1367 *) Fix an output truncation error when on an HTTP >= 1.0 request an
1368 object of size between DEFAULT_BUCKET_SIZE and AP_MIN_BYTES_TO_WRITE
1369 was served through mod_charset_lite (or anything else that would
1370 create a transient bucket in this size range). ap_bucket_make_heap()
1371 silently failed (fixed), transient_setaside() discovered it, but
1372 ap_save_brigade() ignored it (fixed). [Jeff Trawick]
1374 *) Ignore \r\n or \n when using PEEK mode for input filters. The problem
1375 is that some browsers send extra lines at the end of POST requests, and
1376 we don't want to delay sending data back to the user just because the
1377 browser isn't well behaved. [Ryan Bloom]
1379 *) Get SuEXEC working again. We can't send absolute paths to suExec
1380 because it refuses to execute those programs. SuEXEC also wasn't
1381 always recognizing configuration changes made using the autoconf
1384 *) Allow the buildconf process to find the config.m4 files in the correct
1385 order. Basically, we can now name config.m4 files as config\d\d.m4,
1386 and we will sort them correctly when inserting them into the build
1387 process. [Ryan Bloom]
1389 *) Get mod_cgid to use apr calls for creating the actual CGI process.
1390 This also allows mod_cgid to use ap_os_create_priviledged_process,
1391 thus allowing for SuExec execution from mod_cgid. Currently, we do
1392 not support everything that standard SuExec supports, but at least
1393 it works minimally now. [Ryan Bloom]
1395 *) Allow SuExec to be configured from the ./configure command line.
1398 *) Update some of the docs in README and INSTALL to reflect some of
1399 the changes in Apache 2.0 [Cliff Woolley <cliffwoolley@yahoo.com>]
1401 *) If we get EAGAIN returned from the call to apr_sendfile, then we
1402 need to call sendfile again. This gets us serving large files
1403 such as apache_2.0a9.tar.gz on FreeBSD again. [Ryan Bloom]
1405 *) Get the support programs building cleanly again.
1406 [Cliff Woolley <cliffwoolley@yahoo.com>]
1408 *) The Apache/Win32 Apache.exe and dll's now live in bin. The
1409 current directory logic now backs up over bin/ to determine the
1410 server root from the Apache.exe path.
1412 *) Apache/Win32 now follows the standard conventions of mod_foo.so
1413 loadable modules, dynamic libs are all named libfoo.dll, and the
1414 makefile.win populates the include, lib and libexec directories.
1416 *) Apache is now IPv6-capable. On systems where APR supports IPv6,
1417 Apache gets IPv6 listening sockets by default. Additionally, the
1418 Listen, NameVirtualHost, and <VirtualHost> directives support IPv6
1419 numeric address strings (e.g., "Listen [fe80::1]:8080").
1422 *) Modify the install directory layout. Modules are now installed in
1423 modules/. Shared libraries should be installed in libraries/, but
1424 we don't have any of those on Unix yet. All install directories
1425 are modifyable at configure time. [Ryan Bloom]
1427 *) Install all header files in the same directory on Unix. [Ryan Bloom]
1429 *) Get the functions in server/linked into the server, regardless of
1430 which modules linked into the server. This uses the same hack
1431 for Apache that we use for APR and apr-util to ensure all of the
1432 necessary functions are linked. As a part of thise, the CHARSET_EBCDIC
1433 was renamed to AP_CHARSET_EBCDIC for namespace protection, and to make
1434 the scripts a bit easier.
1437 *) Rework the RFC1413 handling to make it thread-safe, use a timeout
1438 on the query, and remove IPv4 dependencies. [Jeff Trawick]
1440 *) Get all of the auth modules to the point that they will install and
1441 be loadable into the server. Our new build/install mechanism expects
1442 that all modules will have a common name format. The auth modules
1443 didn't use that format, so we didn't install them properly.
1446 *) API routines ap_pgethostbyname() and ap_pduphostent() are no longer
1447 available. Use apr_getaddrinfo() instead. [Jeff Trawick]
1449 *) Get "NameVirtualHost *" working in 2.0. [Ryan Bloom]
1451 *) Return HTTP_RANGE_NOT_SATISFIABLE if the every range requested starts
1452 after the end of the response. [Ryan Bloom]
1454 *) Get byterange requests working with responses that do not have a
1455 content-length. Because of the way byterange requests work, we have to
1456 have all of the data before we can actually do the byterange, so we
1457 can compute the content-length in the byterange filter.
1460 *) Get exe CGI's working again on Windows.
1463 *) Get mod_cgid and mod_rewrite to work as DSOs by changing the way
1464 they keep track of whether or not their post config hook has been
1465 called before. Instead of a static variable (which is replaced when
1466 the DSO is loaded a second time), use userdata in the process pool.
1469 Changes with Apache 2.0a9
1471 *) Win32 now requires perl to complete the final install step for users
1472 to build + install on Win32. Makefile.win now rewrites @@ServerRoot@
1473 and installs the conf, htdocs and htdocs/manual directories.
1476 *) Make mod_include use a hash table to associate directive tags with
1477 functions. This allows modules to implement their own SSI tags easily.
1478 The idea is simple enough, a module can insert it's own tag and function
1479 combination into a hash table provided by mod_include. While mod_include
1480 parses an SSI file, when it encounters a tag in the file, it does a
1481 hash lookup to find the function that implements that tag, and passes
1482 all of the relevant data to the function. That function is then
1483 responsible for processing the tag and handing the remaining data back
1484 to mod_include for further processing.
1485 [Paul J. Reder <rederpj@raleigh.ibm.com>]
1487 *) Get rid of ap_new_apr_connection(). ap_new_connection() now has
1488 fewer parameters: the local and remote socket addresses were removed
1489 from the parameter list because all required information is available
1490 via the APR socket. [Jeff Trawick]
1492 *) Distribution directory structure reorganized to reflect a
1493 normal source distribution with external install targets.
1496 *) The MPMs that need multiple segments of shared memory now create
1497 two apr_shmem_t variables, one for each shared memory allocation.
1498 the problem is that we can't determine how much memory will be required
1499 for shared memory allocations once we try to allocate more than one
1500 variable. The MM code automatically aligns the shared memory allocations,
1501 so we end up needing to pad the amount of shared memory we want based
1502 on how many variables will be allocated out of the shared memory segment.
1503 It is just easier to create a second apr_shmem_t variable, and two
1504 shmem memory blocks.
1507 *) Cleanup the export list a bit. This creates a single unified list of
1508 functions exported by APR. The export list is generated at configure
1509 time, and that list is then used to generate the exports.c file.
1510 Because of the way the export list is generated, we only export those
1511 functions that are valid on the platform we are building on.
1514 *) Enable logging the cookie with mod_log_config
1515 [Sander van Zoest <sander@covalent.net>]
1517 *) Fix a segfault in mod_info when it reaches the end of the configuration.
1520 *) Added lib/aputil/ as a placeholder for utility functions which are not
1521 specific to the Apache HTTP Server (but do not make sense with APR).
1522 The first utility is "apu_dbm": a set of functions to work with DBM
1523 files. This first version can be compiled for SDBM or GDBM databases.
1526 *) Complete re-write of mod_include. This makes mod_include a filter that
1527 uses buckets directly. This has now served the FAQ correctly.
1528 [Paul Reder <rederpj@raleigh.ibm.com>]
1530 *) Allow modules to specify the first filter in a sub_request when
1531 making the sub_request. This keeps modules from having to change the
1532 output_filter immediately after creating the sub-request, and therefore
1533 skip the sub_req_output_filter. [Ryan Bloom]
1535 *) Update ab to accept URLs with IPv6 literal address strings (in the
1536 format described in RFC 2732), and to build Host header fields in
1537 the same format. This allows IPv6 literal address strings to be
1538 used with ab. This support has been tested against Apache 1.3 with
1539 the KAME patch, but Apache 2.0 does not yet work with this format
1540 of the Host header field. [Jeff Trawick]
1542 *) Accomodate an out-of-space condition in the piped logs and the
1543 rotatelogs.c code, and no longer churn log processes for this
1544 condition. [Victor J. Orlikowski]
1546 *) Add support for partial writes with apr_sendfile() to core_output_filter.
1549 Changes with Apache 2.0a8
1551 *) Add a directive to mod_mime so that filters can be associated with
1555 *) Get multi-views working again. We were setting the path_info
1556 field incorrectly if we couldn't find the specified file.
1559 *) Fix 304 processing. The core should never try to send the headers
1560 down the filter stack. Always, just setup the table in the request
1561 record, and let the header filter convert it to data that is ready
1565 *) More fixes for the proxy. There are still bugs in the proxy code,
1566 but this has now proxied www.yahoo.com and www.ntrnet.net (my ISP)
1570 *) Fix params for apr_getaddrinfo() call in connect proxy handler.
1573 *) APR: Add new apr_getopt_long function to handle long options.
1574 [B. W. Fitzpatrick <fitz@red-bean.com>]
1576 *) APR: Change apr_connect() to take apr_sockaddr_t instead of hostname.
1577 Add generic apr_create_socket(). Add apr_getaddrinfo() for doing
1578 hostname resolution/address string parsing and building
1579 apr_sockaddr_t. Add apr_get_sockaddr() for getting the address
1580 of one of the apr_sockaddr_t structures for a socket. Change
1581 apr_bind() to take apr_sockaddr_t. [David Reid and Jeff Trawick]
1583 *) Remove the BUFF from the HTTP proxy. This is still a bit ugly, but
1584 I have proxied pages with it, cleanup will commence soon.
1587 *) Make the proxy work with filters. This isn't perfect, because we
1588 aren't dealing with the headers properly. [Ryan Bloom]
1590 *) Do not send a content-length iff the C-L is 0 and this is a head
1591 request. [Ryan Bloom]
1593 *) Make cgi-bin work as a regular directory when using mod_vhost_alias
1594 with no VirtualScriptAlias directives. PR#6829 [Tony Finch]
1596 *) Remove BUFF from the PROXY connect handling. [Ryan Bloom]
1598 *) Get the default_handler to stop trying to deal with HEAD requests.
1599 The idea is to let the content-length filter compute the C-L before
1600 we try to send the data. If we can get the C-L correctly, then we
1601 should send it in the HEAD response.
1604 *) The Header filter can now determine if a body should be sent based
1605 on r->header_only. The general idea of this is that if we delay
1606 deciding to send the body, then we might be able to compute the
1607 content-length correctly, which will help caching proxies to cache
1608 our data better. Any handler that doesn't want to try to compute
1609 the content-length can just send an EOS bucket without data and
1610 everything will just work.
1613 *) Add the referer to the error log if one is available.
1614 [Markus Gyger <mgyger@itr.ch>]
1616 *) Mod_info.c has now been ported to Apache 2.0. As a part of this
1617 change, the root of the configuration tree has been exposed to modules
1619 [Ryan Morgan <rmorgan@covalent.net>]
1621 *) Get the core_output_filter to use the bucket interface directly.
1622 This keeps us from calling the content-length filter multiple times
1623 for a simple static request.
1626 *) We are sending the content-type correctly now.
1627 [Ryan Bloom and Will Rowe]
1629 *) APR on FreeBSD: Fix a bug in apr_sendfile() which caused us to report
1630 a bogus bytes-sent value when the only thing being sent was trailers
1631 and writev() returned an error (or EAGAIN). [Jeff Trawick]
1633 *) Get SINGLE_LISTEN_UNSERIALIZED_ACCEPT working again. This uses the
1634 hints file to determine which platforms define
1635 SINGLE_LISTEN_UNSERIALIZED_ACCEPT.
1638 *) APR: add apr_get_home_directory() [Jeff Trawick]
1640 *) Initial import of 1.3-current mod_proxy. [Chuck Murcko]
1642 *) Not all platforms have INADDR_NONE defined by default. Apache
1643 used to make this check and define INADDR_NONE if appropriate,
1644 but APR needs the check too, and I suspect other applications will
1645 as well. APR now defines APR_INADDR_NONE, which is always a valid
1646 value on all platforms.
1647 [Branko Èibej <brane@xbc.nu>]
1649 *) Destroy the pthread mutex in lock_intra_cleanup() for PR#6824.
1650 [Shuichi Kitaguchi <ki@hh.iij4u.or.jp>]
1652 *) Relax the syntax checking of Host: headers in order to support
1653 iDNS. PR#6635 [Tony Finch]
1655 *) When reading from file buckets we convert to an MMAP if it makes
1656 sense. This also simplifies the default handler because the
1657 default handler no longer needs to try to create MMAPs.
1660 *) BUFF has been removed from the main server. The BUFF code will remain
1661 in the code until it has been purged from the proxy module as well.
1664 *) Byteranges have been completely re-written to be a filter. This
1665 has been tested, and I believe it is working correctly, but it could
1666 doesn't work for the Adobe Acrobat plug-in. The output almost matches
1667 the output from 1.3, the only difference being that 1.3 includes
1668 a content-length in the response, and this does not.
1671 *) APR read/write functions and bucket read functions now operate
1672 on unsigned integers, instead of signed ones. It doesn't make
1673 any sense to use signed ints, because we return the error codes,
1674 so if we have an error we should report 0 bytes read or written.
1677 *) Always compute the content length, whether it is sent or not.
1678 The reason for this, is that it allows us to correctly report
1679 the bytes_sent when logging the request. This also simplifies
1680 content-length filter a bit, and fixes the actual byte-reporing
1681 code in mod_log_config.c
1684 *) Remove AP_END_OF_BRIGADE definition. This does not signify what
1685 it says, because it was only used by EOS and FLUSH buckets. Since
1686 neither of those are required at the end of a brigade, this was
1687 really signifying FLUSH_THE_DATA, but that can be determined better
1688 by checking AP_BUCKET_IS_EOS() or AP_BUCKET_IS_FLUSH. EOS and FLUSH
1689 buckets now return a length of 0, which is actually the amount of data
1690 read, so they make more sense.
1693 *) Allow the core_output_filter to save some data past the end of a
1694 request. If we get an EOS bucket, we only send the data if it
1695 makes sense to send it. This allows us to pipeline request
1696 responses. As a part of this, we also need to allocate mmap
1697 buckets out of the connection pool, not the request pool. This
1698 allows the mmap to outlive the request.
1701 *) Make blocking and non-blocking bucket reads work correctly for
1702 sockets and pipes. These are the only bucket types that should
1703 have non-blocking reads, because the other bucket types should
1704 ALWAYS be able to return something immediately.
1707 *) In the Apache/Win32 console window, accept Ctrl+C to stop the
1708 server, but use Ctrl+Break to initiate a graceful restart
1709 instead of duplicating behavior. [John Sterling]
1711 *) Patch mod_autoindex to set the Last-Modified header based on
1712 the directory's mtime, and add the ETag header. [William Rowe]
1714 *) Merge the 1.3 patch to add support for logging query string in
1715 such a way that "%m %U%q %H" is the same as "%r".
1718 *) Port three log methods from mod_log_config 1.3 to 2.0:
1719 CLF compliant '-' byte count, method and protocol.
1722 *) Add a new LogFormat directive, %c, that will log connection
1723 status at the end of the response as follows:
1724 'X' - connection aborted before the response completed.
1725 '+' - connection may be kept-alive by the server.
1726 '-' - connection will be closed by the server.
1729 *) Expand APR for WinNT to fully accept and return utf-8 encoded
1730 Unicode file names and paths for Win32, and tag the Content-Type
1731 from mod_autoindex to reflect that charset if the the feature
1732 macro APR_HAS_UNICODE_FS is true. [William Rowe]
1734 *) Compute the content length (and add appropriate header field) for
1735 the response when no content length is available and we can't use
1736 chunked encoding. [Jeff Trawick]
1738 *) Changed ap_discard_request_body() to use REQUEST_CHUNKED_DECHUNK,
1739 so that content input filters get dechunked data when using
1740 the default handler. Also removed REQUEST_CHUNKED_PASS.
1743 *) Add mod_ext_filter as an experimental module. This module allows
1744 the administrator to use external programs as filters. Currently,
1745 only filtering of output is supported. [Jeff Trawick]
1747 *) Most Apache functions work on EBCDIC machines again, as protocol
1748 data is now translated (again). [Jeff Trawick]
1750 *) Introduce ap_xlate_proto_{to|from}_ascii() to clean up some of
1751 the EBCDIC support. They are noops on ASCII machines, so this
1752 type of translation doesn't have to be surrounded by #ifdef
1753 CHARSET_EBCDIC. [Jeff Trawick]
1755 *) Fix mod_include. tag commands work again, and the server will
1756 send the FAQ again. This also allows mod_include to set aside
1757 buckets that include partial buckets.
1758 [Ryan Bloom and David Reid]
1760 *) Add suexec support back. [Manoj Kasichainula]
1762 *) Lingering close now uses the socket directly instead of using
1763 BUFF. This has been tested, but since all we can tell is that it
1764 doesn't fail, this needs to be really hacked on.
1767 *) Allow filters to modify headers and have those headers be sent to
1768 the client. The idea is that we have an http_header filter that
1769 actually sends the headers to the network. This removes the need
1770 for the BUFF to send headers.
1773 *) Charset translation: mod_charset_lite handles translation of
1774 request bodies. Get rid of the xlate version of ap_md5_digest()
1775 since we don't compute digests of filtered (e.g., translated)
1776 response bodies this way anymore. (Note that we don't do it at
1777 all at the present; somebody needs to write a filter to do so.)
1780 *) Input filters and ap_get_brigade() now have a input mode parameter
1781 (blocking, non-blocking, peek) instead of a length parameter.
1784 *) Update the mime.types file to the registered media types as
1785 of 2000-10-19. PR#6613 [Carsten Klapp <carsten.klapp@home.net>,
1788 *) Namespace protect some macros declared in ap_config.h
1791 *) Support HTTP header line folding with input filtering.
1794 *) Mod_include works again. This should still be re-written, but at
1795 least now we can serve an SHTML page again.
1798 *) Begin to remove BUFF from the core. Currently, we keep a pointer
1799 to both the BUFF and the socket in the conn_rec. Functions that
1800 want to use the BUFF can, functions that want to use the socket,
1801 can. They point to the same place.
1804 *) apr_psprintf doesn't understand %lld as a format. Make it %ld.
1805 [Tomas "Ögren" <stric@ing.umu.se>]
1807 *) APR pipes on Unix and Win32 are now cleaned up automatically when the
1808 associated pool goes away. (APR pipes on OS/2 were already had this
1809 logic.) This resolvs a fatal file descriptor leak with CGIs.
1812 *) The final line of the config file was not being read if there was
1813 no \n at the end of it. This was caused by apr_fgets returning
1814 APR_EOF even though we had read valid data. This is solved by
1815 making cfg_getline check the buff that was returned from apr_fgets.
1816 If apr_fgets return APR_EOF, but there was data in the buf, then we
1817 return the buf, otherwise we return NULL.
1820 *) Piped logs work again in the 2.0 series.
1823 *) Restore functionality broken by the mod_rewrite security fix:
1824 rewrite map lookup keys and default values are now expanded
1825 so that the lookup can depend on the requested URI etc.
1826 PR #6671 [Tony Finch]
1828 *) Tighten up the syntax checking of Host: headers to fix a
1829 security bug in some mass virtual hosting configurations
1830 that can allow a remote attacker to retrieve some files
1831 on the system that should be inaccessible. [Tony Finch]
1833 *) Add a pool bucket type. This bucket is used for data allocated out
1834 of a pool. If the pool is cleaned before the bucket is destroyed, then
1835 the data is converted to a heap bucket, allowing it to survive the
1839 *) Add a flush bucket. This allows modules to signal that the filters
1840 should all flush whatever data they currently have. There is no way
1841 to actually force them to do this, so if a filter ignores this bucket,
1842 that's life, but at least we can try with this.
1845 *) Add an output filter for sub-requests. This filter just strips the
1846 EOS bucket so that we don't confuse the main request's core output
1847 filter by sending multiple EOS buckets. This change also makes sub
1848 requests start to send EOS buckets when they are finished.
1851 *) Make ap_bucket_(read|destroy|split|setaside) into macros. Also
1852 makes ap_bucket_destroy a return void, which is okay because it
1853 used to always return APR_SUCCESS, and nobody ever checked its
1854 return value anyway.
1855 [Cliff Woolley <cliffwoolley@yahoo.com>]
1857 *) Remove the index into the bucket-type table from the buckets
1858 structure. This has now been replaced with a pointer to the
1859 bucket_type. Also add some macros to test the bucket-type.
1862 *) Renamed all MODULE_EXPORT symbols to AP_MODULE_DECLARE and all symbols
1863 for CORE_EXPORT to AP_CORE_DECLARE (namespace protecting the wrapper)
1864 and retitled API_EXPORT as AP_DECLARE and APR_EXPORT as APR_DECLARE.
1865 All _VAR_ flavors changes to _DATA to be absolutely clear.
1868 *) Add support for /, //, //servername and //server/sharename
1869 parsing of <Directory> blocks under Win32 and OS2.
1870 [Tim Costello, William Rowe, Brian Harvard]
1872 *) Remove the function pointers from the ap_bucket type. They have been
1873 replaced with a global table. Modules are allowed to register bucket
1874 types and use then use those buckets.
1877 *) mod_cgid: In the handler, shut down the Unix socket (only for write)
1878 once we finish writing the request body to the cgi child process;
1879 otherwise, the client doesn't hit EOF on stdin. Small request bodies
1880 worked without this change (for reasons I don't understand), but large
1881 ones didn't. [Jeff Trawick]
1883 *) Remove file bucket specific information from the ap_bucket type.
1884 This has been moved to a file_bucket specific type that hangs off
1885 the data pointer in the ap_bucket type.
1888 *) Input filtering now has a third argument. This is the amount of data
1889 to read from lower filters. This argument can be -1, 0, or a positive
1890 number. -1 means give me all the data you have, I'll deal with it and
1891 let you know if I need more. 0 means give me one line and one line
1892 only. A positive number means I want no more than this much data.
1894 Currently, only 0 and a positive number are implemented. This allows
1895 us to remove the remaining field from the conn_rec structure, which
1899 *) Big cleanup of the input filtering. The goal is that http_filter
1900 understands two conditions, headers and body. It knows where it is
1901 based on c->remaining. If c->remaining is 0, then we are in headers,
1902 and http_filter returns a line at a time. If it is not 0, then we are
1903 in body, and http_filter returns raw data, but only up to c->remaining
1904 bytes. It can return less, but never more.
1905 [Greg Ames, Ryan Bloom, Jeff Trawick]
1907 *) mod_cgi: Write all of the request body to the child, not just what
1908 the kernel would accept on the first write. [Jeff Trawick]
1910 *) Back out the change that moved the brigade from the core_output_filters
1911 ctx to the conn_rec. Since all requests over a given connection
1912 go through the same core_output_filter, the ctx pointer has the
1916 *) Fix another bug in the send_the_file() read/write loop. A partial
1917 send by apr_send would cause unsent data in the read buffer to
1918 get clobbered. Complete making send_the_file handle partial
1919 writes to the network.
1922 *) Fix a couple of type fixes to allow compilation on AIX again
1923 [Victor J. Orlikowski <v.j.orlikowski@gte.net>]
1925 *) Fix bug in send_the_file() which causes offset to be ignored
1926 if there are no headers to send.
1929 *) Handle APR_ENOTIMPL returned from apr_sendfile in the core
1930 filter. Useful for supporting Windows 9* with a binary
1931 compiled on Windows NT.
1934 Changes with Apache 2.0a7
1936 *) Reimplement core_output_filter to buffer/save bucket brigades
1937 across multiple calls to the core_filter. The brigade will be
1938 sent when either MIN_BYTES_TO_SEND or MAX_IOVEC_TO_WRITE
1939 thresholds are hit or the EOS bucket is received.
1942 *) Create experimental filter (buffer_filter) that coalesces bytes
1943 into one large buffer before invoking the next filter in the
1944 chain. This filter is particularly useful with the current
1945 implementation of mod_autoindex when it inserted above the
1946 chunk_filter. mod_autoindex generates a lot of brigades that
1947 containing buckets holding just a few bytes each. The
1948 buffer_filter coalesces these buckets into a single large bucket.
1951 *) Add apr_sendfile() support into the core_output_filter.
1954 *) Add apr_sendv() support into the core_output_filter.
1957 *) Fix mod_log_config so that it compiles cleanly with BUFFERED_LOGS
1958 [Mike Abbott <mja@sgi.com>]
1960 *) Remove ap_send_fb. This is no longer used in Apache, and it doesn't
1961 make much sense, because Apache uses buckets instead of BUFFs now.
1964 *) send_the_file now falls back to a read/write loop on platforms that
1965 do not have sendfile.
1966 [Ryan Bloom and Brian Havard]
1968 *) Install apachectl correctly, and substitute the proper values so
1969 that it works again. [Ryan Bloom]
1971 *) Better(??) handle platforms that lack sendfile().
1974 *) APR now has UUID generation/formatting/parsing support.
1977 *) Begin the http_filter. This is an input filter that understands
1978 the absolute basic amount required to parse an HTTP Request. The
1979 goal is to be able to split headers from request body before passing
1980 the data back to the other filters.
1983 *) Bring forward from 1.3.13 the config directory implementation
1986 *) install apxs if it is created
1989 *) Added APR_IS_STATUS_condition test macros to eliminate canonical error
1990 conversions. [William Rowe]
1992 *) Now that we have ap_add_input_filter(), rename ap_add_filter() to
1993 ap_add_output_filter(). [Jeff Trawick]
1995 *) Multiple build and configuration fixes
1998 -add datadir and localstatedir substitutions
2000 -fix logfilename misspelling
2001 -fix evaluation of installation dir variables and
2002 -replace $foobar by $(foobar) to be usefull in the makefile
2006 -add rules for cross-compiling in rules.mk. Okay, rule to check for
2007 $CC_FOR_BUILD is still missing
2008 -use CHECK_TOOL instead of CHECK_PROG for ranlib
2009 -add missing "AR=@AR@" to severaly Makefile.in's
2010 -cache result for "struct rlimit"
2011 -compile all helper programs with native and cross compiler
2012 and use the native version to generate header file
2013 ["Rüdiger" Kuhlmann <Tadu@gmx.de>]
2015 *) Prepare our autoconf setup for autoconf 2.14a and for cross-
2017 ["Rüdiger" Kuhlmann <Tadu@gmx.de>]
2019 *) Fix a bug where a client which only sends \n to delimit header
2020 lines (netcat) gets a strange looking HTTP_NOT_IMPLEMENTED
2021 message. Start working on ebcdic co-existance with input
2023 [William Rowe, Greg Ames]
2025 *) If mod_so is enabled in the server always create libexec, even
2026 if there are no modules installed in this directory. This is a
2027 requirement for APXS to work correctly.
2030 *) Connection oriented output filters are now stored in the
2031 conn_rec instead of the request_rec. This allows us to add the
2032 output filter in the pre-connection phase instead of the
2033 post_read_request phase, which keeps us from trying to write an
2034 error page before we have a filter to write to the network.
2035 [Ryan Bloom, Jeff Trawick, and Greg Ames]
2037 *) Cleaning up an mmap bucket no longer deletes the mmap. An
2038 mmap can be used across multiple buckets (default_handler with
2039 byte ranges, mod_file_cache, mod_mmap_static), so cleanup of
2040 the mmap itself can't be associated with the bucket.
2043 *) Add .dll caching directive ISAPICacheFile to mod_isapi.
2046 *) Radical surgery to improve mod_isapi support under Win32.
2047 Includes a number of newer ServerSupportFunction calls, support
2048 for ReadClient (in order to retrieve POSTs greater than 48KB),
2049 and general bug fixes to more reliably load ISAPI .dll's and
2050 prevent leaking handle resources. Note: There are still
2051 discrepancies between IIS's and Apache's ServerVariables, and
2052 async calls are still not supported. Additional warnings are
2053 logged to facilitate debugging of unsupported ISAPI calls.
2056 *) Add input filtering to Apache. The basic idea for the input
2057 filters is the same as the ideas for output filters. The biggest
2058 difference is that instead of calling ap_pass_brigade, ap_get_brigade
2059 should be called, and the order of execution for the filter itself is
2060 different. When writing an output filter, a brigade is passed in,
2061 and filters operate directly on that brigade, when done, they call
2062 ap_pass_brigade. Input filters are the exact opposite. Because input
2063 is not a push operation, filters first call ap_get_brigade. When this
2064 function returns, the input filter will be left with a valid brigade.
2065 The input filter should then operate on the brigade, and return.
2068 *) Fix building on BSD/OS using its native make. The build system
2069 falls back to the BSD .include directive on that host platform.
2072 *) Expand dbmmanage to allow -d -m -s -p options for Crypt, MD5,
2073 SHA1 and plaintext password encodings. Make feature tests a
2074 bit more flexible. [William Rowe]
2076 *) Charset translation: mod_charset_lite handles output content
2077 translation in a filter. mod_charset_lite no longer ignores
2078 subrequests. A bunch of cruft related to BUFF's support for
2079 translating request and response bodies was removed.
2082 *) Move the addition of the CORE filter to the post_read_request
2083 hook in http_core.c. This removes the need to add the filter in
2084 multiple places and allows for an SSL module to be added much
2085 simpler. [Ryan Bloom]
2087 *) Fix a security problem that affects certain configurations of
2088 mod_rewrite. If the result of a RewriteRule is a filename that
2089 contains expansion specifiers, especially regexp backreferences
2090 $0..$9 and %0..%9, then it may be possible for an attacker to
2091 access any file on the web server. [Tony Finch]
2093 *) Fix a bug where errors that are detected during early request parsing
2094 don't produce visible HTTP error messages at the browser, because
2095 the core_filter wasn't present. [Greg Ames]
2097 *) Provide apr_socklen_t as a portability aid.
2098 [Victor J. Orlikowski]
2100 *) Overhaul of dbmmanage to allow a groups arg (as in Apache 1.2)
2101 as well as a comment arg to the add, adduser and update cmds.
2102 update allows the user to clear or preserve pw/groups/comment.
2103 Fixed a bug in dbmmanage that prevented the check option from
2104 parsing a password followed by :group... text. Corrected the
2105 seed calcualation for Win32 systems, and added -lsdbm support.
2108 *) Configured mod_auth_dbm to compile with sdbmlib under Win32.
2111 *) Avoid a segfault when parsing .htaccess files. An
2112 uninitialized tree pointer was passed to ap_build_config().
2115 *) Change the way that inet_addr & inet_network are checked for
2116 in APR's configure process to allow BeOS BONE to correctly
2117 find them. With this change BeOS BONE now builds from source
2118 with no problems. [David Reid]
2120 *) Fix a bug in apr_create_process() for Unix. The NULL signifying
2121 the end of the parameters to execve() was stored in the wrong
2122 location, overlaying the storage beyond the newargs[] array and
2123 also passing uninitialized storage to execve(), which would
2124 sometimes fail with EFAULT. [Jeff Trawick]
2126 *) Fix a bug parsing configuration file containers. With a sequence
2127 like this in the config file
2129 <IfModule mod_kilroy.c>
2132 <IfModule mod_lovejoy.c>
2137 the second container would be terminated at the blank line due to
2138 sediment in the buffer from reading the prior </IfModule> and an
2139 error message would be generated for the real </IfModule> for the
2140 second container. Also due to this problem, any two characters
2141 could be used for "</" in the close of a container.
2144 *) ap_add_filter prototype changed to remove the ctx pointer. The
2145 pointer still remains in the filter structure, but it can not be
2146 a part of the ap_add_filter prototype. The reason is that when
2147 the core uses AddFilter to add a filter to the stack it doesn't
2148 know how to allocate the ctx pointer, or even how much memory should
2149 be allocated. The filters will have to be responsible for allocating
2150 the ctx memory when they need it.
2153 *) Add an AddFilter directive. This directive takes a list of filters
2154 that should be activated for the requested resource.
2157 *) apr_snprintf(): Get quad format strings working on OS/390 (and perhaps
2158 some other platforms). [Jeff Trawick]
2160 *) Modify mod_include to be a filter. Currently, it has only been tested
2161 on actual files, but it should work for CGI scripts too.
2164 *) apr_putc(), apr_puts() for Unix: handle buffered files and interrupted
2165 writes. apr_flush() for Unix: handle interrupted writes.
2168 *) NameVirtualHost can now take "*" as an argument instead of
2169 an IP address. This allows you to create a purely name-based
2170 virtual hosting server that does not have any IP addresses in
2171 the configuration file and which ignores the local address
2172 of any connections. PR #5595, PR #4455 [Tony Finch]
2174 *) Fix some compile warnings in mod_mmap_static.c
2175 [Mike Abbott <mja@sgi.com>]
2177 *) Fix chunking problem with CGI scripts. The general problem was that
2178 the CGI modules were adding an EOS bucket and then the core added an
2179 EOS bucket. The chunking filter finalizes the chunked response when it
2180 encounters an EOS bucket. Because two EOS buckets were sent, we
2181 finalized the response twice. The fix is to make sure we only send one
2182 EOS, by utilizing a flag in the request_rec.
2185 *) apr_put_os_file() now sets up the unget byte appropriately on Unix
2186 and Win32. Previously, the first read from an apr_file_t set up via
2187 apr_put_os_file() would return a '\0'. [Jeff Trawick]
2189 *) Mod_cgid now creates a single element bucket brigade, with a pipe
2190 bucket, instead of using BUFF's and ap_r*.
2193 *) APRVARS.in no longer overwrites the EXTRA_LIBS variable.
2194 [Mike Abbott <mja@sgi.com>]
2196 *) Remove ap_bopenf from buff code. This required modifying the file_cache
2197 code to use APR file's directly instead of going through BUFFs.
2200 *) Fix compile break on some platforms for mod_mime_magic.c
2201 [John K. Sterling <sterling@covalent.net>]
2203 *) Fix merging of AddDefaultCharset directive.
2204 PR #5872 (1.3) [Jun Kuriyama <kuriyama@imgsrc.co.jp>]
2206 *) Minor revamp of the rlimit sections of code. We now test
2207 explicitly for setrlimit and getrlimit. Also, unixd_set_rlimit()
2208 is now "available" even if the platform doesn't support
2209 the rlimit family (it's just a noop though). [Jim Jagielski]
2211 *) Migrate the pre-selection of which MPM to use for specific
2212 platforms to hints.m4, which contains (or should contain)
2213 all platform specific "hints". [Jim Jagielski]
2215 *) Remove IOLs from Apache. With filtering, IOLs are no longer necessary
2218 *) Add tables with non-string/binary values to APR.
2221 *) Fix some bad calls to ap_log_rerror() in mod_rewrite.
2224 *) Update PCRE to version 3.2. [Ryan Bloom]
2226 *) Change the way buckets' destroy functions are called so that
2227 they can be more directly used when changing the type of a
2228 bucket in place. [Tony Finch]
2230 *) Add generic support for reference-counting the resources used by
2231 buckets, and alter the HEAP and MMAP buckets to use it. Change
2232 the way buckets are initialised to support changing the type of
2233 buckets in place, and use it when setting aside TRANSIENT buckets.
2234 Change the implementation of TRANSIENT buckets so that it can be
2235 mostly shared with IMMORTAL buckets, which are now implemented.
2238 Changes with Apache 2.0a6
2240 *) Add support to Apache and APR for dsos on OS/390. [Greg Ames]
2242 *) Add a chunking filter to Apache. This brings us one step closer
2243 to removing BUFF. [Ryan Bloom]
2245 *) ap_add_filter now adds filters in a LIFO fashion. The first filter
2246 added to the stack is the last filter to be called. [Ryan Bloom]
2248 *) Apache 2.0 has been completely documented using Scandoc. The
2249 docs can be generated by running 'make docs'. [Ryan Bloom]
2251 *) Add filtered I/O to Apache. This is based on bucket brigades,
2252 Currently the buckets still use BUFF under the covers, but that
2253 should change quickly. The only currently written filter is the
2254 core filter which just calls ap_bwrite. [The Apache Group]
2256 *) APR locks on Unix: Let APR_LOCKALL locks work when APR isn't
2257 built with thread support. [Jeff Trawick]
2259 *) Abort configuration if --with-layout was specified and there's
2260 no layout definition file. [Ken Coar]
2262 *) Add support for '--with-port=n' option to configure. [Ken Coar]
2264 *) Add support for extension methods for the Allow response header
2265 field, and an API routine for accessing r->allowed and the
2266 list of extension methods in a unified manner. [Ken Coar]
2268 *) mod_cern_meta: fix broken file reading loop in scan_meta_file().
2269 [Rob Simonson <simo@us.ibm.com>]
2271 *) Get xlate builds working again. The apr renaming in 2.0a5 broke
2272 APACHE_XLATE builds. [Jeff Trawick]
2274 *) A configuration file parsing problem was fixed. When the
2275 configuration file started with an IfModule/IfDefine container,
2276 only the last statement in the container would be retained.
2279 Changes with Apache 2.0a5
2281 *) Perchild is serving pages after passing them to different child
2282 processes. There are still a lot of bugs, but this does work. I
2283 have made requests against the same installation of Apache, and had
2284 different servers use different user IDs to serve the responses.
2285 This change moves to using socketpair instead of an AF_UNIX socket.
2288 *) Perchild MPM still doesn't work perfectly, but it is serving pages.
2289 It can't seem to pass between child processes yet, but I think we
2290 are closer now than before. This moves us back to using Unix
2291 Domain Sockets. [Ryan Bloom]
2293 *) libapr functions and types renamed with apr_ prefix.
2294 #include "apr_compat.h" for 1.3.x backwards compat
2297 *) Fix problems with APR sockaddr handling on Win32. It didn't always
2298 return the right information on the local socket address.
2299 [Gregory Nicholls <gnicholls@level8.com>]
2301 *) ap_recv() on Win32: Set bytes-read to 0 on error.
2302 [Gregory Nicholls <gnicholls@level8.com>]
2304 *) Add an option to not detach from the controlling terminal without
2305 going into single process mode. This allows for much easier
2306 debugging of the process startup code. [Ryan Bloom]
2308 *) ab: don't use perror() to report the failure of an APR function.
2311 *) Make dexter, mpmt_pthread, and perchild MPMs not destroy the
2312 scoreboard on graceful restarts.
2315 *) Fix segfault/SIGSEGV when running gzip from mod_mime_magic.c.
2316 An invalid ap_proc_t was passed to ap_create_process().
2319 *) Allow modules to register filters. Those filters are still
2320 never called, but this is a step in the right direction.
2321 [Ryan Bloom and Greg Stein]
2323 *) Register the mod_cgid daemon process for cleanup so that it is
2324 killed at termination if it does not die when the parent gets
2325 SIGTERM. This change is to fix occasional problems where the
2326 process stays around. Bugs in similar logic in mod_rewrite and
2327 mod_include were also fixed. [Jeff Trawick]
2329 *) Fix a bug in the time handling. Basically, we were imploding a time
2330 in ap_parseHTTPdate, but it had bogus data in the exploded time format.
2331 Namely, tm_usec and tm_gmtoff were not filled out. ap_implode_time
2332 uses those two fields to adjust the time value. Because of the HTTP
2333 spec, both of those values can be zero'ed out safely. This fixes
2334 the bug correctly. [Ryan Bloom]
2336 *) Fix a couple of place in the Windows code where the wrong error
2337 code was being returned. [Gregory Nicholls <gnicholls@level8.com>]
2339 *) Fix POOL_DEBUG (at least for prefork mpm). [Dean Gaudet]
2341 *) Added the APR_EOL_STR macro for platform dependent differences in
2342 logfiles and other raw text (such as all APR files). Fixes logfiles
2343 not terminated with cr/lf sequences in Win32. [William Rowe]
2345 *) Move all strings functions in APR to src/lib/apr/strings and create
2346 apr_strings.h for the prototypes. [Ryan Bloom]
2348 *) APR lock fixes: when using SysV sems, flock(), or fcntl(), be sure
2349 to repeat the syscall until we stop getting EINTR. I noticed a
2350 related problem at termination (SIGTERM) on FreeBSD when using
2351 fcntl(). Apache 1.3 had these new loops too. Also, make the flock()
2352 implementation work properly with child init. Previously, ap_lock()
2353 was essentially a no-op because all children were using different
2354 locks and thus nobody ever blocked. [Jeff Trawick]
2356 *) The htdocs/ tree has been moved out of the CVS source tree into
2357 a separate area for easier development. This has NO EFFECT on
2358 end-users or Apache installations. [Ken Coar]
2360 *) Integrate the mod_dav module for WebDAV protocol handling. This
2361 adds the dav and dav_fs modules, the SDBM library, and additional
2362 XML handling utilities. [Greg Stein]
2364 *) Clean out obsolete names (from httpd.h) for the HTTP Status Codes
2367 *) Update the lib/expat-lite/ library (bring forward changes from
2368 the Apache 1.3 repository). [Greg Stein]
2370 *) If sizeof(long long) == sizeof(long), then prefer long in APR
2371 configure.in. [Dave Hill <ddhill@zk3.dec.com>]
2373 *) Add ap_sendfile for Tru64 Unix. Also, add an error message for
2374 machines where sendfile is detected, but nobody has written ap_sendfile.
2375 [Dave Hill <ddhill@zk3.dec.com>]
2377 *) Compile fixes in mod_mmap_static. [Victor J. Orlikowski]
2379 *) ab would start up more connections than needed, then quit when the
2380 desired number were finished. Also fixed a logic error involving
2381 ab keepalives. [Victor J. Orlikowski]
2383 *) WinNT: Implement non-blocking pipes with timeouts to communicate
2384 with CGIs. Apache 2.0a4 had non-blocking pipes but without
2385 timeouts (i.e, if a timeout was specified, the pipe reverted to
2386 a full blocking pipe). Now the behaviour is more in line with
2387 Unix non-blocking pipes.
2390 *) WinNT: Implement accept socket reuse. Using mod_file_cache to
2391 cache open file handles along with accept socket reuse enables
2392 Apache 2.0 to serve non-keepalive requests for static files at
2393 3x the rate of Apache 1.3.(e.g, Apache 1.3 will serve 400 rps
2394 and Apache 2.0 will serve almost 1200 rps on my system).
2397 *) Merge mod_mmap_static function into mod_file_cache. mod_file_cache
2398 supports two config directives, mmapfile (same behavious as
2399 mod_mmap_static) and cachefile. Use the cachefile directive
2400 to cache open file handles. This directive only works on systems
2401 that have implemented the ap_sendfile API. cachefile works today
2402 on Windows NT, but has not been tested on any flavors of Unix.
2405 *) Cleanup the configuration. With the last few changes the
2406 configuration process automatically:
2407 inherits information about how to build from APR. Allowing
2408 APR to inform Apache that it should or should not use -ldl
2410 Detects which mod_cgi should be used mod_cgi or mod_cgid,
2411 based on the threading model
2413 Apache calls APR's configure process before finishing it's
2414 configuration processing, allowing for more information flow
2419 *) Change Unix and Win32 ap_setsockopt() so that APR_SO_NONBLOCK
2420 with non-zero argument makes the socket non-blocking. BeOS and
2421 OS/2 already worked this way. [Jeff Trawick]
2423 *) ap_close() now calls ap_flush() for buffered files, so write
2424 operations work a whole lot better on buffered files.
2427 *) Fix error messages issued from MPMs which explain where to change
2428 compiled-in limits (e.g., ThreadsPerChild, MaxClients, StartTreads).
2431 *) ap_create_pipe() now leaves pipes in blocking state. (This helps
2432 reduce the number of syscalls on Unix.) ap_set_pipe_timeout() is
2433 now the way that the blocking state of a pipe is manipulated.
2434 ap_block_pipe() is gone. [Jeff Trawick]
2436 *) Correct the problem where the only local host name that the IP stack
2437 can discover are 'undotted' private names. If no fully qualified
2438 domain name can be identified, the default ServerName will be set to
2439 the machine's IP address string. A warning is always provided if the
2440 ServerName not specified, but assumed. Solves PR6215 [William Rowe]
2442 *) Repair problems with config file processing which caused segfault
2443 at init when virtual hosts were defined and which caused ServerName to
2444 be ignored when there was no valid DNS setup. [Jeff Trawick]
2446 *) Removed pointless ap_is_aborted macro function. [Roy Fielding]
2448 *) Add ap_sendfile implementation for AIX
2449 [Victor J. Orlikowski]
2451 *) Repair C++ compatibility in ap_config.h, apr_file_io.h,
2452 apr_network_io.h, and apr_thread_proc.h.
2453 [Tyler J. Brooks <tylerjbrooks@home.com>, Jeff Trawick]
2455 *) Bring the allocation and pool debugging code back into a working
2456 state. This will need to be tested as so far it's only been used on
2459 *) Change configuration command setup to be properly typesafe when in
2460 maintainer mode. Note that this requires a compiler that can initialise
2461 unions. [Ben Laurie]
2463 *) Turn on buffering for config file reads. Part of this was to
2464 repair buffered I/O support in Unix and implement buffered
2465 ap_fgets() for all platforms. [Brian Havard, Jeff Trawick]
2467 *) Win32: Fix problem where UTC offset was not being set correctly
2468 in the access log. Problem reported on news group by Jerry Baker.
2471 *) Fix segfault when reporting this type of syntax error:
2472 "</container> without matching <container> section", where
2473 container is VirtualHost or Directory or whatever.
2476 *) Prevent the source code for CGIs from being revealed when using
2477 mod_vhost_alias and the CGI directory is under the document root
2478 and a user makes a request like http://www.example.com//cgi-bin/cgi
2479 as reported in <news:960999105.344321@ernani.logica.co.uk>
2482 *) Add support for the new Beos NetwOrking Environment (BONE)
2485 *) xlate: ap_xlate_conv_buffer() now tells the caller when the
2486 final input char is incomplete; ap_bwrite_xlate() now handles
2487 incomplete final input chars. [Jeff Trawick]
2489 *) Yet another update to saferead/halfduplex stuff -- need to ensure
2490 that a bhalfduplex call occurs before logging or else DNS and
2491 such can delay the last packet of the response. [Dean Gaudet]
2493 *) Some syscall reduction in APR on unix -- don't seek when setting
2494 up an mmap; and don't fcntl() more than once per socket.
2497 *) When mod_cgid is started as root, the cgi daemon now switches
2498 to the configured User/Group (like other httpd processes)
2499 instead of continuing as root. [Jeff Trawick]
2501 *) The prefork MPM now uses an APR lock for the accept() mutex.
2502 It has not been getting a lock at all recently. httpd -V now
2503 displays APR's selection of the lock mechanism instead of the
2504 symbols previously respected by prefork. [Jeff Trawick]
2506 *) Change the mmap() feature test to check only for existence.
2507 The previous check required features not used by Apache.
2510 *) Fix a couple of bugs in mod_cgid: The cgi arguments were
2511 sometimes mangled. The len parm to accept() was not
2512 initialized, leading sometimes to an endless loop of failed
2513 accept() calls on OS/390 and anywhere else that failed the call
2514 if the len was negative. Use <sys/un.h> for struct sockaddr_un
2515 instead of declaring it ourselves to fix a compilation problem
2516 on Solaris. [Jeff Trawick]
2518 *) Add Resource limiting code back into Apache 2.0. [Ryan Bloom]
2520 *) Fix zombie process problem with mod_cgi. [Jeff Trawick]
2522 *) Port mod_mmap_static to 2.0. Make it go faster. [Greg Ames]
2524 *) Fix storage overlay when loading dsos. Symptom: Apache dies at
2525 initialization if ALLOC_DEBUG is defined; no known symptom
2526 otherwise. [Jeff Trawick]
2528 *) Fix typo in configure script when checking for mod_so. bash
2529 doesn't seem to have a problem but /bin/sh on Solaris does.
2530 Symptom: "./configure: test: unknown operator =="
2533 *) Rebind the Win32 NT and 9x services control into the MPM.
2534 All console, WinNT SCM and Win9x pseudo-service control code is
2535 now wrapped within the WinNT MPM.
2538 *) Make a copy of getenv("PATH") before storing for later use. Some
2539 getenv() implementations use the same storage for successive calls.
2540 CGIs on OS/390 had a bad PATH due to this. [Jeff Trawick]
2542 *) Server Tokens work in 2.0 again. This also propogates the change
2543 to allow just the product name in the server string using
2547 Changes with Apache 2.0a4
2549 *) EBCDIC: Rearrange calls to ap_checkconv() so that most handlers
2550 won't need to call it. [Greg Ames, Jeff Trawick]
2552 *) Move pre_config hook call to between configuration read and config
2553 tree walk. This allows all modules to implement pre_config hooks
2554 and know that they will be called at an appropriate time.
2557 *) mod_cgi, mod_cgid: Make ScriptLog directive work again.
2560 *) Add pre-config hooks back to all modules.
2563 *) Fix a SIGSEGV in ap_md5digest(), which is used when you have
2564 ContentDigest enabled and we can't/don't mmap the file.
2567 *) We now report the correct line number for syntax errors in config
2568 files. [Ryan Bloom, Greg Stein, Jeff Trawick]
2570 *) Brought mod_auth_digest up to synch with 1.3, fixed ap_time_t-
2571 related bugs, and changed shmem/locking to use apr API. Shared-mem
2572 is currently disabled, however, because of problems with graceful
2573 restarts. [Ronald Tschalär]
2575 *) Fix corruption of IFS variable in --with-module= handling.
2576 Depending on the user's shell or customization thereof, there
2577 would be errors generating ap_config_auto.h later in the configure
2578 procedure. [Jeff Trawick]
2580 *) mod_cgi: Restore logging of stderr from child process when ScriptLog
2581 isn't used (as in 1.3), except that on Unix it is now logged via
2582 ap_log_rerror() instead of by the child having STDERR_FILENO refer
2583 to the error log. [Greg Ames, Jeff Trawick]
2585 *) Add '-D' argument processing for run time configuration defines.
2588 *) Organize http_main.c as independent code, such that no code or
2589 global data is exported from it. WIN32 will dynamically link it
2590 to the server core, so this will prevent mutual dependency.
2593 *) Add separate dynamic linkage tags APR_EXPORT(), APR_EXPORT_NONSTD()
2594 and APR_VAR_EXPORT to correctly resolve apr functions and globals.
2597 *) Add Win9x service execution and Ctrl+C/Ctrl+Break/Shutdown handlers.
2598 [William Rowe, Jan Just Keijser <KEIJSERJJ@logica.com>]
2600 *) Add mod_charset_lite for configuring character set translation.
2603 *) Add '-n' option to htpasswd to make it print its user:pw record
2604 on stdout rather than having to frob a text file. [Ken Coar]
2606 *) Fix saferead. Basically, we flush the output buffer if a read on the
2610 *) APR: Add ap_xlate_get_sb() so that an app can find out whether or not
2611 a conversion is single-byte only. [Jeff Trawick]
2613 *) BEOS: ap_shutdown should return APR_SUCCESS or errno. Note that
2614 the BeOS 5.0 documentation says that shutdown doesn't work yet.
2617 *) Fix some minor errors where pid was being manipulated as an int
2618 instead of the portable pid_t. [Roy Fielding]
2620 *) Fix some error log prints that were printing the pointer to a
2621 structure rather than the pid within the structure.
2622 [Jeff Trawick, Roy Fielding]
2624 *) ab: Fix a command-line processing bug; track bad headers in
2625 err_response; support reading headers up to 2K.
2626 [Ask Bjoern Hansen <ask@valueclick.com>]
2628 *) Fix ap_resolve_env() so that it handles new function added in a prior
2629 alpha (see "Added the capability to do ${ENVVAR} constructs in the
2630 config file.") as well as the constructs used by mod_rewrite.
2631 [Paul Reder <rederpj@raleigh.ibm.com>]
2633 *) Apache 2.0 builds and runs on OS/390. [Jeff Trawick, Greg Ames]
2635 *) Change the EBCDIC support in functions for MD5, SHA1, and base 64 to use
2636 APR to perform translation, instead of accessing the hard-coded tables
2637 in 1.3's ebcdic.c. [Jeff Trawick]
2639 *) Fix some bugs (mostly lost 1.3 code) in ab's command-line processing.
2642 *) Add the ability to hook into the config file reading phase. Basically
2643 if a directive is specified EXEC_ON_READ, then when that directive is
2644 read from the config file, the assocaited function is executed. This
2645 should only be used for those directives that must muck with HOW the
2646 server INTERPRETS the config. This should not be used for directives
2647 that re-order or replace items in the config tree. Those changes should
2648 be made in the pre-config step.
2651 *) Add mod_example to the build system.
2654 *) APR: Add ap_xlate_conv_byte() to convert one char between single-
2655 byte character sets. [Jeff Trawick]
2657 *) Pick up various EBCDIC fixes from 1.3 (from Martin
2658 Kraemer and Oliver Reh originally according to the change log).
2661 *) Fix a couple of problems in RFC1413 support (controlled by the
2662 IdentityCheck directive). Apache did not build the request string
2663 properly and more importantly Apache would loop forever if the
2664 would-be ident server dropped the connection before sending a
2665 properly terminated response. [Jeff Trawick]
2667 *) apxs works in 2.0.
2670 *) Reliable piped logs work in 2.0.
2673 *) Introduce a hash table implementation into APR to be used for
2674 replacing tables and other random data structures in Apache.
2677 *) Add some more error reporting to htpasswd in the case of problems
2678 generating or accessing the temporary file. Also, pass in a
2679 buffer if the implementation knows how to use it (i.e., if L_tmpnam
2680 is defined). [Ken Coar]
2682 *) Configure creates config.nice now containing your configure
2683 options. Syntax: ./config.nice [--more-options]
2686 *) Fix various return code problems in APR on Win32. For most of
2687 these, APR was returning APR_EEXIST instead of GetLastError()/
2688 WSAGetLastError(). [Jeff Trawick]
2690 *) Make piped logs work again in version 2.0
2693 *) Add VPATH support to UNIX build system of Apache and APR.
2696 *) Fix ap_tokenize_to_argv to respect the const arguments that are
2700 *) Fix mm's memcpy/memset macros, pointer arithmetic was broken.
2701 Patch submitted to author.
2704 *) Fix mm configuration on Solaris 8 x86 and OS/390. Don't require
2705 /sbin in PATH on FreeBSD (all submitted to rse previously)
2708 *) Fix building Pthread-based MPMs on OpenBSD
2709 [Sascha Schumann] PR#26
2711 *) Fix ap_readdir() problem on systems where d_name[] field in
2712 struct dirent is declared with only one byte. (This problem only
2713 affected multithreaded builds.) This caused a segfault during
2714 pool cleanup with mod_autoindex on Solaris (Solaris 8 x86, at
2715 least). [Jeff Trawick]
2717 *) Fix some make-portability problems on at least Tru64, Irix
2719 [Sascha Schumann] PR#18, PR#39
2721 *) Add ap_sigwait() to support old-style sigwait() on systems
2722 like OS/390 and UnixWare.
2725 *) Add POSIX-thread flags for more platforms.
2728 *) Fix some minor bugs in ap_strerror(). Teach ap_strerror()
2729 (on Unix, at least) to handle resolver errors. Fix a bug in
2730 the definition of APR_ENOMEM so that ap_strerror() can spit
2731 out the correct error message for it.
2734 Changes with Apache 2.0a3
2736 *) mod_so reports ap_os_dso_error() if ap_dso_load() fails
2739 *) API: *HOOK* macros now have an AP_ prefix
2742 *) Win32: Eliminate redundant calls to initialize winsock.
2743 [Tim Costello <timcostello@ozemail.com.au>]
2745 *) Fix bugs initializing ungetchar for pipes.
2746 [Chia-liang Kao <clkao@CirX.ORG>]
2748 *) The ab program in the src/support directory is now portable using
2752 *) Support directory is being compiled when the server is built
2755 *) The configure option --with-program-name has been added to allow
2756 developers to rename the executable at configure time. This also
2757 changes the name of the config files to match the executable's name.
2760 *) mod_autoindex: Add `IndexOptions +VersionSort', to nicely sort filenames
2761 containing version numbers. [Martin Pool]
2763 *) ap_open(..,APR_OS_DEFAULT,..) uses perms 0666 instead of 0777 on
2764 Unix; access_log and error_log now created with these perms; non-
2765 Unix is unaffected [Jeff Trawick]
2767 *) Finished move of ap_md5 routines to apr_md5. Removed ap_md5.h.
2768 Replaced more magic numbers with MD5_DIGESTSIZE.
2769 [William Rowe, Roy Fielding]
2771 *) Win32: Get mod_auth_digest compiling and added to the Windows
2772 build environment. Not tested and I'd be suprised if it
2773 actually works. [Bill Stoddard]
2775 *) Revamp the Win32 make environment. Makefiles have been removed and
2776 Apache.dsw created to bring together all the pieces. Create new file
2777 os/win32/BaseAddr.ref to define module base addresses (to prevent
2778 dll relocation at start-up).
2779 [William Rowe, Greg Marr, Tim Costello, Bill Stoddard]
2781 *) [EBCDIC] Port Paul Gilmartin's CRLF patch from 1.3. This replaces most
2782 of the \015, \012, and \015\012 constants with macros.
2783 [Greg Ames <gregames@us.ibm.com>]
2785 *) Add ap_xlate_open() et al for translation of text between different
2786 character sets. The initial implementation requires iconv().
2789 *) More FAQs and answers from comp.infosystems.www.servers.unix.
2790 [Joshua Slive <slive@finance.commerce.ubc.ca>]
2792 *) CGI output is being timed out now.
2795 *) Fix the problem with dieing quietly. dupfile now takes a pool which
2796 is used by the new apr file. There is no reason to create a new file
2797 with the same lifetime as the original file.
2800 *) Win32: Attempt to eliminate dll relocation at start-up by specifying
2801 module base addresses. This will help shooting seg faults
2802 in the field. [William Rowe <wrowe@lnd.com>]
2804 *) Update Apache on Windows documentation. Add new document
2805 describing how to compile Apache on Windows.
2806 [William Rowe <wrowe@lnd.com>]
2808 *) ap_set_pipe_timeout(), ap_poll(), and APR_SO_TIMEOUT now take
2809 microseconds instead of seconds. Some storage leaks and other
2810 minor bugs in related code were fixed. [Jeff Trawick]
2812 *) Win32: First cut at getting mod_isapi working under 2.0
2813 [William Rowe <wrowe@lnd.com>]
2815 *) First stab at getting mod_auth_digest working under 2.0
2816 quick change summary:
2817 - moved the random byte generation (ap_generate_random_bytes) into APR
2818 - now uses ap_time_t
2819 - compiles and runs on linux
2821 [Brian Martin <bmartin@penguincomputing.com>]
2823 *) Win32: Move the space stripping of physical service names
2824 fix up from Apache 1.3. #include'ing "ap_mpm.h" fixes up an
2825 unresolved symbol. Add dependency checking to the
2826 CreateService call to ensure TCPIP and AFP (winsock) is started
2828 [William Rowe <wrowe@lnd.com>]
2830 *) Win32: Add code to perform latebinding on functions that may
2831 not exist on all levels of Windows where Apache runs. This
2832 is needed to allow Apache to start-up on Win95/98. All calls
2833 to non portable functions should be protected with
2834 ap_oslevel checks to prevent runtime segfaults.
2835 [William Rowe <wrowe@lnd.com>]
2837 *) Fix fallback default values for SHM_R and SHM_W [Martin Kraemer]
2839 *) Get lingering_close() working again. [Dean Gaudet, Jeff Trawick]
2841 *) Win32: Get non-blocking CGI pipe reads working under Windows NT.
2842 This addresses PR 1623. Still need to address timing out runaway
2843 CGI scripts. [Bill Stoddard]
2845 *) Win32: Make ap_stat Windows 95/98 friendly
2846 [William Rowe <wrowe@lnd.com>]
2848 *) Win32: Fix a bug in ap_get_oslevel which causes GetVersionEx() to
2849 always fail. Need to initialise the dwOSVersionInfoSize member of the
2850 OSVERSIONINFO struct before calling GetVersionEx, so GetVersionEx
2853 The patch also enhances ap_get_oslevel (and the associated enum) to
2854 handle selected service packs for NT4, and adds recognition for
2855 Windows 2000. This is useful, eg. if we can recognise NT4 SP2 then
2856 we can use ReadFileScatter and WriteFileGather in readwrite.c.
2857 [Tim Costello <Tim.Costello@BTFinancialgroup.com>]
2859 *) Get mod_rewrite building and running, and mod_status building for Win NT
2860 [Allan Edwards <ake@raleigh.ibm.com>]
2862 *) Patch to port mod_auth_db to the 2.0 api and also to support
2863 Berlekey DB 3.0. It works for me with both Berkeley DB 3.0.55 and
2864 2.7.7. It should work with version 1 as well but I haven't tested it.
2865 [Brian Martin <bmartin@penguincomputing.com>]
2867 *) Get APR DSO code working under Windows. Includes cross platform
2869 [Tim.Costello@BTFinancialgroup.com]
2871 *) Fix some of the Windows APR time functions.
2874 *) FAQ changes related to tidying up historical documents on the web site.
2875 [Joshua Slive <slive@finance.commerce.ubc.ca>]
2877 *) Move Windows DSO code into APR.
2880 *) Eliminate apr_win.h and apr_winconfig.h (and the ugly #ifdefs they cause).
2881 Now, apr.h and apr_config.h are generated from apr.hw and apr_config.hw
2882 at build time. At this point, the server will not compile on Windows because
2883 of the recent DSO commits. Fixing those next.
2884 [Bill Rowe & Bill Stoddard]
2886 *) Added error checking for file I/O APR routines.
2887 [Jon Travis <jtravis@covalent.net>]
2889 *) APR: Don't use the values of resolver error codes for the
2890 corresponding APR error codes. On Unix and Win32, return the
2891 proper APR error code after a resolver error. [Jeff Trawick]
2893 Changes with Apache 2.0a2
2895 *) Renamed the executable back to httpd on all platforms other
2899 *) Allow BeOS to survive restarts, log properly and a few
2900 small things it had problems with due to the way it setup
2901 users and groups. [David Reid]
2903 *) Get mod_rewrite working with APR locks
2904 [Paul Reder <rederpj@raleigh.ibm.com>]
2906 *) Actually remove the sempahore when the lock cleanup routine
2907 is called on BeOS. [David Reid]
2909 *) Clear hook registrations between reads of the config file.
2910 When DSOs are unloaded and re-loaded the old hook pointers may
2911 no longer be valid. This fix eliminates potential segfaults.
2912 [Allan Edwards <ake@raleigh.ibm.com>]
2914 *) Fix a problem with Sigfunc not being defined or bypassed
2915 if sigaction() wasn't found. [Jim Jagielski]
2917 *) Fix the locking mechanism on BSD variants. They now use fcntl
2918 locks. This allows the server to start and serve pages.
2921 *) First cut at getting the Win32 installer to work
2922 [William Rowe <wrowe@lnd.com>]
2924 *) Get htpasswd compiling under Windows
2925 [William Rowe <wrowe@lnd.com>]
2927 *) Change the log message for a bind() failure to show the
2928 interface and port number. [Jeff Trawick]
2930 *) Import the documentation from 1.3.12 and bring parts of it
2931 up-to-date with respect to the changes that have occurred
2935 *) BeOS MPM updated. CGI bug on BeOS fixed. IP addresses
2936 now logged correctly on BeOS.
2939 *) Create one makefile for all Win32 distributions (NT/2000/95/98).
2940 Makefile.win includes the same user interface as the old
2942 [William Rowe <wrowe@lnd.com>, Jeff Trawick <trawick@us.ibm.com>]
2944 *) Win32 exec now uses COMSPEC environment string for command
2945 shell path resolution.
2946 [William Rowe <wrowe@lnd.com>] PR#3715
2948 *) Win32: ap_connect() was not returning correct error condition
2950 [Allen Prescott <allen@clanprescott.com>]
2952 *) Win32: ap_open() was broken on Win9x because an NT-specific
2953 flag was passed to CreateFile. ap_puts() added an unnecessary
2955 [Jeff Trawick <trawick@us.ibm.com>]
2957 *) Put in Korean and Norwegian index.html pages (2.0 and 1.3)
2958 which where donated by Lee Kuk Hyun and Lorant Czaran. 'Fixed'
2959 confusing ee/et name and made all extensions language/dialect
2960 rather than country reflecting. Changed example files to
2961 explicit reflect the ISO charset and added a few common
2962 ones to the example config [dirkx]
2964 *) Extend external module capability. To use this, you call
2965 configure with --with-module=path/to/mod1,path/to/mod2,etc.
2968 *) Backported the various "default charset" fixes from 1.3.12,
2969 including the AddDefaultCharset directive. [Jim Jagielski]
2971 *) Added the capability to do ${ENVVAR} constructs in the
2972 config file. E.g. 'ServerAdmin ${POSTMASTER}'. As commited
2973 it does this on a line by line basis; i.e. if the envvar
2974 expands to something with spaces you have to protect it
2975 by adding quotes around it (Unless of course you expect it
2976 to contains more than one argument. Alternatively you
2977 can compile it on a per token basis; which is what people
2978 usually expect by setting RESOLVE_ENV_PER_TOKEN. But this
2979 hampers fancier hacks.
2980 [Dirk-Willem van Gulik]
2982 *) Changed the 'ErrorDocument' syntax in that it NO longer
2983 supports the asymetric
2985 ErrorDocument 301 "Some message
2987 Note the opening " quote, without a closing quote. It now
2988 has either the following syntaxes
2990 ErrorDocument XXX /local/uri
2991 ErrorDocument XXX http://valid/url
2992 ErrorDocument XXX "Some Message"
2994 The recognition heuristic is: if it has a space it
2995 is a message. If it has no spaces and starts with a /
2996 or is a valid URL then treat it that way. Otherwise it
2997 is assumed to be a message.
2999 This breaks backward compatibility but makes live a hell
3000 of a lot easier for GUI's and config file parsers.
3001 [Dirk-Willem van Gulik]
3003 *) Changed 'CacheNegotiatedDocs' from its present/not-present
3004 syntax into a 'on' or 'off' syntax. As it currently is the
3005 only non nesting token which uses NO_ARGS and thus is an
3006 absolute pain for any config interface automation. This
3007 breaks backward compatibility. [Dirk-Willem van Gulik]
3009 *) Add ability to add external modules to the build process. This is
3010 done with --with-module=/path/to/module. Modules can only be added
3011 as static modules at this point.
3014 Changes with Apache 2.0a1
3016 *) Fix FreeBSD 3.3 core dump.
3017 Basically, ap_initialize() needs to get called before
3018 create_process(), since create_process() passes op_on structure
3019 to semop() to get a lock, but op_on isn't initialized until
3020 ap_initialize() calls setup_lock(). Here is a slight
3021 rearrangement to main() which calls ap_initialize() earlier...
3022 [Jeff Trawick <trawick@us.ibm.com>]
3024 *) Enable Apache to use sendfile/TransmitFile API
3025 [Bill Stoddard, David Reid, Paul Reder]
3027 *) Re-Implement Win32 APR network I/O APIs and most of the file I/O
3031 *) Make file I/O and network I/O writev/sendv APIs consistent.
3032 Eliminate use of ap_iovec_t and use Posix struct iovec.
3033 Use seperate variable on ap_writev to set the number of iovecs
3034 passed in and number of bytes written.
3037 *) Adapt file iol to use APR functions. Replaced ap_open_file()
3038 with ap_create_file_iol(). ap_create_file_iol() requires that
3039 the file be opened prior to the call using ap_open().
3042 *) Port mod_include and mod_cgi to 2.0
3043 [Paul Reder, Bill Stoddard]
3045 *) ap_send{,v}, ap_recv, ap_sendfile API clarification --
3046 bytes_read/bytes_written is always valid (never -1). Plus
3047 some fixes to buff.c to correct problems introduced by the
3048 errno => ap_status_t changes a while back. Plus a fix to
3049 chunked encoding introduced right at the beginning of 2.0.
3052 *) Revamped UNIX build system to use autoconf and libtool.
3053 [Manoj Kasichainula, Sascha Schumann]
3055 *) port mod_rewrite to 2.0. [Paul J. Reder <rederpj@raleigh.ibm.com>]
3057 *) More rigorous checking of Host: headers to fix security problems
3058 with mass name-based virtual hosting (whether using mod_rewrite
3059 or mod_vhost_alias).
3060 [Ben Hyde, Tony Finch]
3062 *) Add back support for UseCanonicalName in <Directory> containers.
3063 [Manoj Kasichainula]
3065 *) Added APLOG_STARTUP log type. This allows us to write an error
3066 message without any of the date and time information. As a part
3067 of this change, I also removed all of the calls to fprintf(stderr
3068 and replaced them with calls to ap_log_error using APLOG_STARTUP
3069 writing to stderr is no longer portable, because we don't direct
3070 stderr to the error log on all platforms.
3073 *) Convert error logging functions to take errno as an argument.
3074 This makes our error logs more portable, because some Windows API's
3075 don't set errno. This change allows us to still output a valid
3076 message on all of our platforms.
3079 *) mod_mime_magic runs in 2.0-dev now.
3080 [Paul Reder <rederpj@raleigh.ibm.com>]
3082 *) sendfile has been added to APR.
3083 [John Zedlewski <zedlwski@Princeton.EDU>]
3085 *) buff.c has been converted to no longer use errno.
3086 [Manoj Kasichainula]
3088 *) mod_speling runs in 2.0-dev now: a bug in readdir_r handling and
3089 interface adaption to APR functions did it. [Martin Kraemer]
3091 *) Support DSOs properly on 32-bit HP-UX 11.0
3092 [Dilip Khandekar <dilip@cup.hp.com>]
3094 *) Updated MM in APR source tree from version 1.0.8 to 1.0.11
3095 [Ralf S. Engelschall]
3097 *) Cleaned APR build environment integration and bootstrap APR
3098 automatically for developers from src/Configure.
3099 [Ralf S. Engelschall]
3101 *) Fixed building of src/support/htpasswd.c
3102 [Ralf S. Engelschall]
3104 *) When generating the Location: header, mod_speling forgot
3105 to escape the spelling-fixed uri. (Forw-Port from 1.3)
3108 *) Moved mod_auth_digest.c from experimental to standard. [Roy Fielding]
3110 *) Change all pools to APR contexts. This is the first step to
3111 incorporating APR into Apache. [Ryan Bloom]
3113 *) Move "handler not found" warning message to below the check
3114 for a wildcard handler. [Dirk <dirkm@teleport.com>, Roy Fielding]
3115 PR#2584, PR#2751, PR#3349, PR#3436, PR#3548, PR#4384, PR#4795, PR#4807
3117 *) Support line-continuation feature in config.option file and
3118 allow the loading of multiple option sections at once via
3119 ``--with-option=<section1>,<section2>,...''
3120 [Ralf S. Engelschall]
3122 *) Rebuilt CVS repository with Apache 1.3.9 as basis. [Roy Fielding]
3124 Changes with Apache MPM
3126 *) Use asynchronous AcceptEx() and a completion port to accept and
3127 dispatch connections to threads in Windows NT/2000.
3130 *) Implement WINNT Win32 MPM from original Win32 code in http_main.c
3133 *) Implement the APACI --with-option facility
3134 (per default used the config.option file).
3135 [Ralf S. Engelschall]
3137 *) MPM BEOS port. [David Reid <abb37@dial.pipex.com>]
3139 *) Start to implement module-defined hooks that are a) fast and b) typesafe.
3140 Replace pre_connection module call with a register_hook call and
3141 implement pre_connection as a hook. The intent is that these hooks will
3142 be extended to allow Apache to be multi-protocol, and also to allow the
3143 calling order to be specified on a per-hook/per-module basis.
3146 *) Implement mpm_* methods as "modules". Each method gets its own
3147 subdir in src/modules (eg: src/modules/prefork). Selection
3148 of method uses Rule MPM_METHOD. [Jim Jagielski]
3150 *) Port the hybrid server from the apache-apr repository as
3151 mpm_mpmt_pthread. [Manoj Kasichainula]
3153 *) os/unix/unixd.[ch]: detach, setuid, setgid, stuff which will be common
3154 amongst the unix MPMs.
3156 *) mpm_prefork: throw away all the alarm/timeout crud; and clean up the
3157 signal handling for the new world order. [Dean Gaudet]
3159 *) Crude ap_thread_mutex abstraction so that we get the pthread stuff out
3160 of alloc.c for now. [Dean Gaudet]
3162 *) Handle partial large writes correctly. [Ben Laurie]
3164 *) Eliminate conn_rec's pointer to server. All it knows is the base server
3165 based on IP/port. [Ben Laurie]
3167 *) Port a bunch of modules to the new module structure.
3168 ["Michael H. Voase" <mvoase@midcoast.com.au>]
3170 *) I/O layering and BUFF revamp. See docs/buff.txt. [Dean Gaudet]
3172 *) Basic restructuring to introduce the MPM concept; includes various
3173 changes to the module API... better described by
3174 docs/initial_blurb.txt. [Dean Gaudet]
3176 Changes with Apache pthreads
3178 *) New buff option added: BO_TIMEOUT. It describes the timeout for
3179 buff operations (generally over a network).
3180 [Dean Gaudet, Ryan Bloom, Manoj Kasichainula]
3182 *) Created http_accept abstraction. Added 4 new functions (not exported):
3183 init_accept(), begin_accepting_requests(), get_request(),
3184 stop_accepting_requests() [Bill Stoddard]
3186 *) Fix to ap_rprintf call that allows mod_info to work properly.
3187 [James Morris <jmorris@intercode.com.au>]
3189 *) user and ap_auth_type fields were moved from connection_rec to
3190 request_rec. [Ryan Bloom]
3192 *) Removed the ap_block_alarms and ap_unblock_alarm calls. These aren't
3193 needed in a threaded server.
3195 *) Initial pthread implementation from from Dean's apache-nspr code.
3196 [Bill Stoddard, Ryan Bloom]
3199 Changes with Apache 1.3.9
3201 *) Remove bogus error message when a redirect doesn't set Location.
3202 Instead, use an empty string to avoid coredump if the error message
3203 was supposed to include a location. [Roy Fielding]
3205 *) Don't allow configure to include mod_auth_digest unless it is
3206 explicitly requested, even if the user asked for all modules.
3209 *) Translate module names to dll names for OS/2 so that they are no more
3210 than 8 characters long and have an extension of "dll" instead of "so".
3213 *) Print out pointer to Rule DEV_RANDOM when truerand lib not found.
3214 Fix test-compile check to check for randbyte instead of trand32.
3215 Use ap_base64encode_binary/decode instead of copy in mod_auth_digest.c
3216 and tweak to make Amaya happier. [Ronald Tschalär]
3218 *) Ensure that the installed expat include files are world readable,
3219 just like the other header files. [Martin Kraemer]
3221 *) Fixed generated AddModule adjustments in APACI's `configure' script
3222 in order to allow (new) modules like mod_vhost_alias to be handled
3223 correctly (which was touched by the adjustments for mod_alias).
3224 [Ralf S. Engelschall]
3226 *) For binary builds, add -R flag to apachectl to work around the lack of
3227 an absolute path to the ./libexec directory where the libhttp.ep file
3228 is needed for SHARED_CORE architectures. [Randy Terbush]
3230 *) WIN32: Create the CGI script process as DETACHED. This may solve the
3231 problem observed by some Win95/98 users where they get CGI script
3232 output sent to the console. [Bill Stoddard]
3234 *) Fix (re)naming in the uuencode/decode section. The ap/ap_
3235 routines are now called ap_base64* and are 'plain' (i.e., no
3236 pool access or anything clever). Inside util.c the routines acting
3237 like pstrdup are called ap_pbase64encode() and ap_pbase64decode().
3238 The oddly named ap_uuencode(), ap_uudecode() are kept around for
3239 now but deprecated. [dirkx]
3241 *) Clean up the base64 and SHA1 additions and make sure they are
3242 represented in the ApacheCore.def, ApacheCoreOS2.def, and httpd.exp
3243 files. [Roy Fielding]
3245 *) WIN32: Migrate to InstallShield 5.5 and provide a bit more error
3246 checking. Allow compiling on VS 6.0. [Randy Terbush]
3248 *) Fixed assumption of absolute paths in binbuild.sh. [Tony Finch]
3250 *) Use TestCompile to search for the truerand library (rather than blindly
3251 assuming its existence). If it is not found, complain (but do not
3252 exit - yet). [Martin Kraemer]
3254 *) We forgot to add the new exported function names to
3255 src/support/httpd.exp. [Bill Stoddard, Randy Terbush]
3257 *) Add description of -T command-line option to usage().
3258 [Ralf S. Engelschall]
3260 *) For "some" platforms (notably, EBCDIC based ones), libos needs to be
3261 searched only AFTER libap has been searched, because libap needs
3262 some symbols from libos. [Martin Kraemer]
3264 *) Fix conflict with original mod_digest related to the symbol of the
3265 module dispatch list (which has to be unique for DSO and follow the
3266 usual conventions for the installation procedure).
3267 [Ralf S. Engelschall]
3269 *) Add a dbm-library check for the "usual places" (-ldbm, -lndbm, -ldb)
3270 for other platforms as well. [Martin Kraemer]
3272 *) Make ap_sha1.c compile for EBCDIC platforms: replace remaining LONG
3273 types by AP_LONG and replace reference to renamed variable 'ubuf'
3274 by 'buffer'. [Martin Kraemer]
3276 Changes with Apache 1.3.8 [not released]
3278 *) Flush the output buffer immediately after sending an error or redirect
3279 response, since the result may be needed by the client to abort a
3280 long data transfer or restart a series of pipelined requests.
3281 [Tom Vaughan <tvaughan@aventail.com>, Roy Fielding]
3283 *) PORT: Improved compilation and DSO support on Sequent DYNIX/ptx.
3284 [Ian Turner <iant@sequent.com>] PR#4735
3286 *) Local struct mmap in http_core.c conflicted with system structure
3287 name on DYNIX -- changed to mmap_rec. [Roy Fielding] PR#4735
3289 *) Added updated mod_digest as modules/experimental/mod_auth_digest.
3290 [Ronald Tschalär <ronald@innovation.ch>]
3292 *) Fix a memory leak where the module counts were getting messed
3293 up across restarts. [David Harris <dharris@drh.net>]
3295 *) CIDR addresses such as a.b.c.d/24 where d != 0 weren't handled
3296 properly in mod_access.
3297 ["Paul J. Reder" <rederpj@raleigh.ibm.com>] PR#4770
3299 *) RewriteLock/RewriteMap didn't work properly with virtual hosts.
3300 [Dmitry Khrustalev <dima@bog.msu.su>] PR#3874
3302 *) PORT: Support for compaq/tandem/com.
3303 [Michael Ottati <michael.ottati@compaq.com>, dirkx]
3305 *) Added SHA1 password encryption support to easy migration from
3306 Netscape servers. See support/SHA1 for more information.
3307 Caused the separation of ap_md5.c into md5, sha1 and a general
3308 ap_checkpass.c with just a validate_passwd routine. Added a
3309 couple of flags to support/htpasswd. Some reuse of the to64()
3310 function; hence renamed to ap_to64().
3311 [Dirk-Willem van Gulik, Clinton Wong <clintdw@netcom.com>]
3313 *) Change for EBCDIC platforms (TPF and BS2000) to correctly deal
3314 with ASCII/EBCDIC conversions in "ident" query.
3315 [David McCreedy <McCreedy@us.ibm.com>]
3317 *) Get rid of redefinition warning on MAC_OS_X_SERVER platform.
3318 Change "Power Macintosh" to Power* so if uname prints "Power Book"
3319 we're still happy on Rhapsody platforms. [Wilfredo Sanchez]
3321 *) Fix SIGSEGV on some systems because the Vary fix below included
3322 a call to table_do with a variable argument list that was not
3323 NULL terminated. Replaced with better implementation. [Roy Fielding]
3325 Changes with Apache 1.3.7 [not released]
3327 *) The "Vary" response header field is now sanitised right before
3328 the header is sent back to the client. Multiple "Vary" fields
3329 are combined, and duplicate tokens (e.g., "Vary: host, host" or
3330 "Vary: host, negotiate, host, accept-language") are reduced to
3331 single instances. This is a better solution than the force-no-vary
3332 one (which is still valid for clients that can't cope with Vary
3333 at all). PR#3118 [Dean Gaudet, Roy Fielding, Ken Coar]
3335 *) Portability changes for BeOS. [David Reid abb37@dial.pipex.com]
3337 *) Link DSO's with "gcc -shared" instead of "ld -Bshareable" at
3338 least on Linux and FreeBSD for now.
3341 *) Win32: More apache -k restart work. Restarts are now honored
3342 immediately and connections in the listen queue are -not- lost.
3343 This is made possible by the use of the WSADuplicateSocket()
3344 call. The listeners are opened in the parent, duplicated, then
3345 the duplicates are passed to the child. The original listen sockets
3346 are not closed by the parent across a restart, thus the listen queue
3348 [Bill Stoddard <stoddard@raleigh.ibm.com>]
3350 *) Fix handling of case when a client has sent "Expect: 100-continue"
3351 and we are going to respond with an error, but get stuck waiting to
3352 discard the body in the pointless hope of preserving the connection.
3353 [Roy Fielding, Joe Orton <jeo101@york.ac.uk>] PR#4499, PR#3806
3355 *) Fix 'configure' to work correctly with SysV-based versions of
3356 'tr' (consistent with Configure's use as well). [Jim Jagielski]
3358 *) apxs: Add "-S var=val" option which allows for override of CFG_*
3359 built-in values. Add "-e" option which works like -i but doesn't
3360 install the DSO; useful for editing httpd.conf with apxs. Fix
3361 editing code so that multiple invocations of apxs -a will not
3362 create duplicate LoadModule/AddModule entries; apxs can now be
3363 used to re- enable/disable a module. [Wilfredo Sanchez]
3365 *) Win32: Update the server to use Winsock 2. Specifically, link with
3366 ws2_32.lib rather than wsock32.lib. This gives us access to
3367 WSADuplcateSocket() in addition to some other enhanced comm APIs.
3368 Win 95 users may need to update their TCP/IP stack to pick up
3369 Winsock 2. (See http://www.microsoft.com/windows95/downloads/)
3370 [Bill Stoddard stoddard@raleigh.ibm.com]
3372 *) Win32: Redirect CGI script stderr (script debug info) into the
3373 error.log when CGI scripts fail. This makes Apache on Win32
3374 behave more like Unix.
3375 [Bill Stoddard stoddard@raleigh.ibm.com]
3377 *) Fixed `httpd' usage display: -D was missing.
3378 [Ralf S. Engelschall] PR#4614
3380 *) Fix `make r' test procedure in src/regex/: ap_isprint was not found.
3381 [Ralf S. Engelschall] PR#4561, PR#4562
3383 *) OS/2: Fix problem with accept lock semaphores where server would die with
3384 "OS2SEM: Error 105 getting accept lock. Exiting!"
3385 [Brian Havard] PR#4505
3387 *) Add DSO support for DGUX 4.x using gcc. Tested on x86 platforms.
3388 [Randy Terbush <randy@covalent.net>]
3390 *) Add the new mass-vhost module (mod_vhost_alias.c) developed and
3391 used by Demon Internet, Ltd. [Tony Finch <fanf@demon.net>]
3393 *) Better GCC detection for DSO flags under Solaris 2 where the `cc'
3394 command potentially _is_ GCC. [Ralf S. Engelschall]
3396 *) Fix apxs build issues on AIX
3397 [Rasmus Lerdorf <rasmus@raleigh.ibm.com>]
3399 *) DocumentRoot Checking: Under previous versions, when Apache
3400 first started up, it used to do a stat of each DocumentRoot to
3401 see if it existed and was a directory. If not, then an error
3402 message was printed. THIS HAS BEEN DISABLED. If DocumentRoot
3403 does not exist, you will get error messages in error_log. If
3404 the '-t' command line option is used (to check the configuration)
3405 the check of DocumentRoot IS performed. An additional command
3406 line option, '-T', has been added if you want to avoid the
3407 DocumentRoot check even when checking the configuration.
3410 *) Win32: The query switch "apache -S" didn't exit after showing the
3411 vhost settings. That was inconsistent with the other query functions.
3412 [Bill Stoddard - Fixed by Martin on Unix in 1.3.4]
3414 *) Win32: Changed behaviour of apache -k restart.
3415 Previously, the server would drain all connections in the stack's
3416 listen queue before honoring the restart. On a busy server, this
3417 could take hours. Now, a restart is honored almost immediately.
3418 All connections in Apache's queues are handled but connections in
3419 the stack's listen queue are discarded. Restart triggered by
3420 MaxRequestPerChild is unchanged.
3421 [Bill Stoddard <stoddard@raleigh.ibm.com>]
3423 *) Win32: Eliminated unnecessary call to wait_for_multiple_objects in
3424 the accept loop. Good for a 5% performance boost. Cleaned up
3425 parent/child process management code.
3426 [Bill Stoddard <stoddard@raleigh.ibm.com>]
3428 *) Added ceiling on file size for memory mapped files.
3429 [John Giannandrea <jg@meer.net>] PR#4122
3431 *) Fix ndbm.h include problems with brain-dead glibc >= 2.1 which
3432 has ndbm.h in a non-standard db1/ subdir. PR#4431, PR#4528
3433 [Henri Gomez <gomez@slib.fr>, Ralf S. Engelschall]
3435 *) Determine AP_BYTE_ORDER for ap_config_auto.h and already

3438 *) Allow .module files to specify libraries with Lib:.
3441 *) Allow SetEnvIf[NoCase] to test environment variables as well
3442 as header fields and request attributes. [Ken Coar]
3444 *) Fix mod_autoindex's handling of ScanHTMLTitles when file
3445 content-types are "text/html;parameters". PR#4524 [Ken Coar]
3447 *) Remove "mxb" support from mod_negotiation -- it was a draft feature
3448 never accepted into any standard, and it opens up certain DoS
3449 attacks. [Koen Holtman <Koen.Holtman@cern.ch>]
3451 *) TestCompile updated. We can now run programs and output the
3452 results during the Configure process. [ Jim Jagielski]
3454 *) The source is now quad (long long) aware as needed. Specifically,
3455 the Configure process determines the correct size of off_t and
3456 *void. When the OS/platform/compiler supports quads, ap_snprintf()
3457 provides for the 'q' format qualifier (if quads are not available,
3458 'q' is silently "demoted" to long). [Jim Jagielski]
3460 *) When the username or password fed to htpasswd is too long, include the
3461 size limit in the error message. Also report illegal characters
3462 (currently only ':') in the username. Add the size restrictions
3463 to the man page. [Ken Coar]
3465 *) Fixed the configure --without-support option so it doesn't result in
3466 an infinite loop. [Marc Slemko]
3468 *) Piped error logs could cause a segfault if an error occured
3469 during configuration after a restart.
3470 [Aidan Cully <aidan@panix.com>] PR#4456
3472 *) If a "Location" field was stored in r->err_headers_out rather
3473 than r->headers_out, redirect processing wouldn't find it and
3474 the server would core dump on ap_escape_html(NULL). Check both
3475 tables and raise HTTP_INTERNAL_SERVER_ERROR with a log message
3476 if Location isn't set. [Doug MacEachern, Ken Coar]
3478 *) Add RULE_EXPAT, the src/lib/ directory structure, and a modified copy
3479 of the Expat 1.0.2 distribution. [Greg Stein]
3481 *) Replace regexec() calls with calls to a new API stub function
3482 ap_regexec(). This solves problems with DSO modules which use the regex
3483 library. [Jens-Uwe Mager <jum@helios.de>, Ralf S. Engelschall]
3485 *) Add 'Request_Protocol' special keyword to mod_setenvif so that
3486 environment variables can be set according to the protocol version
3487 (e.g., HTTP/0.9 or HTTP/1.1) of the request. [Ken Coar]

3504 *) Support for server-parsed and multiview-determined ReadmeName and
3505 HeaderName files in mod_autoindex. Removed the restriction on
3506 "/"s in ReadmeName and HeaderName directives since the *sub_req*
3507 routines will deal with the access issues. (It's now possible to
3508 have {site|group|project|customer|...} wide readmes and headers.)

3526 *) Do setgid() before initgroups() in http_main; some platforms
3527 zap the grouplist when setgid() is called. This was fixed in

3544 being newer than Configuration so that it is less likely to fail
3545 when using APACI and shadow sources. [Wilfredo Sanchez]
3547 *) PORT: Add initial support for Mac OS (versions 10.0 and
3548 greater). Use Mac OS X Server layout for now. Clean up dyld code
3549 in unix/os.c, and don't install the dyld error handlers, which
3550 are no longer needed in Mac OS. [Wilfredo Sanchez]
3552 *) Rename Rhapsody layout to "Mac OS X Server". Change install
3553 locations to appropriate ones for user-built (as opposed to
3554 system) installs. [Wilfredo Sanchez]
3556 *) Modify mod_autoindex's handling of AddDescription so that the
3557 behaviour matches the documentation. [Ken Coar] PR#1898, 3072.
3559 *) Add functionality to the install-bindist.sh script created by
3560 binbuild.sh to use tar when copying distribution files to the
3561 serverroot. This allows upgrading an existing installation
3562 without nesting the new distribution in the old.
3564 install-bindist.sh now detects the local perl5 path to install
3565 apxs and dbmmanage with proper path to perl interpreter.
3567 Add an install-binsupport target which copies the source files
3568 for apxs and dbmmanage to bindist to allow these scripts to
3569 be properly installed relative to the destination serverroot.

3686 htpasswd utility was limiting passwords to only 8 characters.
3689 *) EBCDIC platforms: David submitted patches for two bugs in the
3690 MD5 digest port for EBCDIC machines:
3691 a) the htdigest utility overwrote the old contents of the digest file
3692 b) the Content-MD5 header value (ContentDigest directive) was wrong
3693 when the returned file was not converted from EBCDIC, but was a
3694 binary (e.g., image file) in the first place.
3695 [David McCreedy <mccreedy@us.ibm.com>]
3697 *) support/htpasswd now permits the password to be specified on the

3699 need to be maintained by scripts -- particularly in the Win32
3700 environment. [Ken Coar]
3702 *) Win32: Win32 multiple services patch. Added capability to install and
3703 run multiple copies of apache as individual services.

3736 *) OS/2: Rework CGI handling to use spawn*() instead of fork/exec, achieving
3737 a roughly 5 fold speed up. [Brian Havard]
3739 *) proxy ftp: instead of using the hardwired string "text/plain" as
3740 a fallback type for files served by the ftp proxy, use the
3741 ap_default_type() function to determine the configured type.
3742 This allows for special configurations like
3743 <Directory proxy:ftp://some.host>
3744 DefaultType gargle/blurb
3746 Additionally, add the Content-Encoding: header to FTP proxy replies
3747 when the encoding is defined (by the AddEncoding directive).
3748 Because it was missing, it was almost impossible to browse compressed
3749 files using the FTP proxy (works now perfectly in Communicator).
3750 The ftp proxy now also returns the Date: and Server: header lines (if not
3751 much else... This code is "somewhat" broken) like normal requests do.
3754 *) Be more smart in APACI's configure script when determining the UID/GID
3755 for User/Group directives and use the determined UID/GID to initialize
3756 the permissions on the proxycachedir.
3757 [Dirk-Willem van Gulik, Ralf S. Engelschall]
3759 *) Changed the forking-prior-to-cleanup in the proxy module to first

3761 the number of fork()s from one/request to just the odd one an hour.

3791 *) M_INVALID needed a value within the scope of METHODS so that unknown
3792 methods can be access controlled. [Roy Fielding] PR#3821
3794 *) Added PassAllEnv; makes server's entire environment available
3795 to CGIs and SSIs executed within directive's scope. [Ken Coar]
3797 *) ap_uuencode() always added two trailing '='s and encoding of
3798 8 bit characters on a machine with signed char may produced
3799 incorrect results. Additionally ap_uuencode() should now
3800 work correctly on EBCDIC platforms.
3801 [Ronald Tschalär <ronald@innovation.ch>] PR#3411
3803 *) WIN32: Binary installer now runs the configuration DLL before
3804 the reboot prompt (which is only given if MSVCRT.DLL system
3805 DLL is new or updated). This should avoid the configuration
3806 directory being empty after installation. [Paul Sutton]
3807 PR#3767, 3800, 3827, 3850, 3900, 3953, 3988

3816 have been reported with flock() locking (probably related to kernel
3817 version). [Dean Gaudet] PR#2723, 3531

3830 *) ap_isxdigit was somehow neglected when adding the ap_isfoo() macros
3831 for 8-bit safeness. [Dean Gaudet]
3833 *) PORT: Use -fPIC instead of -fpic on Solaris and SunOS for compiling DSOs
3834 because SPARCs have a small machine-specific maximum size for the Global
3835 Offset Table which is often exceeded when compiling one of the larger
3836 third-party modules with Apache. [Peter Urban <Peter.Urban@epfl.ch>] PR#3977
3838 *) Move the directive `ExtendedStatus' in httpd.conf-dist-win _after_ the

3865 *) Add Apple's Mac OS X Server Layout "Rhapsody" to config.layout.
3868 *) Add cgidir, htdocsdir, iconsdir variables to Makefile.tmpl in order
3869 to make platform installations easier. [Wilfredo Sanchez]
3871 *) In configure, do not append the target name to the directory path if
3872 the path already contains "apache". [Ralf S. Engelschall]
3874 *) SIGPIPE is now ignored by the server core. The request write routines
3875 (ap_rputc, ap_rputs, ap_rvputs, ap_rwrite, ap_rprintf, ap_rflush) now
3876 correctly check for output errors and mark the connection as aborted.
3877 Replaced many direct (unchecked) calls to ap_b* routines with the
3878 analogous ap_r* calls. [Roy Fielding]
3880 *) Enhanced mod_rewrite's mapfile handling: The in-core cache for text and
3881 DBM format mapfiles now uses a 4-way hash table with LRU functionality.
3882 Furthermore map lookups for non-existent keys are now cached as well.
3883 Additionally "txt" maps are now parsed with simple string functions
3884 instead of using ap_pregcomp(). As a side effect a bug that prevented
3885 the usage of keys containing the "," character was fixed.
3886 The changes drastically improve the performance when large rewrite maps
3888 [Michael van Elst <mlelstv@serpens.swb.de>, Lars Eilebrecht] PR#3160

3896 *) Replaced use of WIN32 define with HAVE_DRIVE_LETTERS to indicate
3897 when the OS allows a DOS drive letter within pathnames. [Brian Havard]
3899 *) Add %V to mod_log_config, this logs the hostname according to the
3900 UseCanonicalName setting (this is the pre-1.3.4 behaviour of
3901 %v). Useful for mass vhosting. [Tony Finch <dot@dotat.at>]
3903 *) Add support for \n and \t to mod_log_config, can be used to produce
3904 more reliable logs with multiline entries. [Tony Finch <dot@dotat.at>]
3906 *) Fixed a few compiler nits. [John Bley <jbb6@acpub.duke.edu>]

3924 for integration into other HTML sources. David updated the ab man page
3925 as well and added some missing descriptions. Thanks!

3929 characters in the range 0x80 to 0xff (for example accented characters).

3932 *) Added conditional logging based upon environment variables to
3933 mod_log_config. mod_log_referer and mod_log_agent
3934 are now deprecated. [Ken Coar]
3936 *) Allow apache acting as a proxy server to relay the real
3937 reason of a failure to a client rather than the "internal
3938 server error" it does currently. The general exposure mechanism
3939 can be triggered by any module by setting the "verbose-error-to"
3940 note to "*"; this allows more than just proxy errors to be exposed.
3941 [Cliff Skolnick, Roy Fielding, Martin Kraemer] Related to PR#3455, 4086
3943 *) Moved man pages for ab and apachectrl to section 8.
3944 [Wilfredo Sanchez, Roy Fielding]
3946 *) Added -S option to install.sh so that options can be passed to
3947 strip on some platforms. [Ralf S. Engelschall, Wilfredo Sanchez]
3949 *) Tweak modules Makefile generated by Configure so that it handles
3950 the test case of no modules being selected. [chaz@reliant.com]
3952 *) Added a <LimitExcept method ...> sectioning directive that allows
3953 the user to assign authentication control to any HTTP method that
3954 is *not* given in the argument list; i.e., the logical negation
3955 of the <Limit> directive. This is particularly useful for controlling
3956 access on methods unknown to the Apache core, but perhaps known by
3957 some module or CGI script. [Roy Fielding, Tony Finch]
3959 *) Prevent apachectl from complaining if the PIDFILE exists but
3960 does not contain a process id, as might occur if the server is
3961 being rapidly restarted. [Wilfredo Sanchez]
3963 *) Win32: Add global symbols missing from ApacheCore.def. [Carl Olsen]
3965 *) Entity tag comparisons for If-Match and If-None-Match were not being
3966 performed correctly -- weak tags might cause false positives. Also,
3967 strong comparison wasn't properly enforced in all cases.
3968 [Roy Fielding, Ken Coar, Dean Gaudet] PR#2065, 3657
3970 *) OS/2: Supply OS/2 error code instead of errno on semaphore errors.
3973 *) Work around a bug in Lynx regarding its sending "Negotiate: trans"
3974 even though it doesn't understand TCN. [Koen Holtman, Roy Fielding]
3976 *) Added ap_size_list_item(), ap_get_list_item(), and ap_find_list_item()
3977 to util.c for parsing an HTTP header field value to extract the next
3978 list item, taking into account the possible presence of nested comments,
3979 quoted-pairs, and quoted-strings. ap_get_list_item() also removes
3980 insignificant whitespace and lowercases non-quoted tokens.
3981 [Roy Fielding] PR#2065
3983 *) proxy: The various calls to ap_proxyerror() can return HTTP/1.1 status
3984 code different from 500. This allows the proxy to, e.g., return
3985 "403 Forbidden" for ProxyBlock'ed URL's. [Martin Kraemer] Related to PR#3455
3987 *) Fix ordering of language variants for the case where the traditional
3988 negotiation algorithm is being used with multiple language variants
3989 and no Accept-Language. [James Treacy <treacy@debian.org>] PR#3299, 3688
3991 *) Do not round the TCN quality calculation to 5 decimal places,
3992 unlike RFC 2296, because the calculation might need 12 decimal places
3993 to get the right result. [Roy Fielding]
3995 *) Remove unused code to disable transparent negotiation when
3996 negotiating on encoding only, as we now handle encoding too
3997 (though this is nonstandard for TCN), remove charset=ISO-8859-1
3998 fiddle from the fiddle-averse RVSA comparison, and fix bugs in
3999 some debugging statements within mod_negotiation. [Koen Holtman]
4001 *) Fixed a rare memory corruption possibility in mod_dir if the index
4002 file is negotiable and no acceptable variant can be found.
4003 [Dean Gaudet, Roy Fielding, Martin Kraemer]
4005 *) Win32: Add new config directive, ScriptInterpreterSource, to enable
4006 searching the Win32 registry for script interpreters.
4009 *) Win32: The compiled-in default filename for the error log is now
4010 error.log, which matches the default in the distributed httpd.conf.
4013 *) Win32: Any error messages from -i or -u command line options are now
4014 displayed on the console output rather than sent to the error log.
4015 Also the "Running Apache..." message is not output unless Apache is
4016 going to serve requests. [Paul Sutton]
4018 *) Rework the MD5 authentication scheme to use FreeBSD's algorithm,
4019 and use a private significator ('$apr1$') to mark passwords as
4020 being smashed with our own algorithm. Also abstract the password
4021 checking into a new ap_validate_password() routine. [Ken Coar]
4023 *) Win32: The filename validity checker now allows "COM" but refuses
4024 access to "COM1" through "COM4". This allows filenames such
4025 as "com.name" to be served. [Paul Sutton] PR#3769.
4027 *) BS2000: Adapt to the new ufork() system call interface which will
4028 make subtasking easier on the OSD/POSIX mainframe environment.
4031 *) Add a compatibility define for escape_uri() -> ap_escape_uri() to
4032 ap_compat.h. [David White <david@persimmon.com>] PR#3725
4034 *) Make NDBM file suffix determination for mod_rewrite more accurate, i.e.
4035 use `.db' instead of `.pag' not only for FreeBSD, but also when
4036 the NDBM library looks like Berkeley-DB based.
4037 [Ralf S. Engelschall] PR#3773
4039 *) Add ability to handle DES or MD5 authentication passwords.
4040 [Ryan Bloom <rbb@Raleigh.IBM.Com>]
4042 *) Fix O(n^2) memory consumption in mod_speling. [Dean Gaudet]
4044 *) SECURITY: Avoid some buffer overflow problems when escaping
4045 quoted strings. (This overflow was on the heap and we believe
4046 impossible to exploit.) [Rick Perry <perry@ece.vill.edu>]
4048 *) Let src/Configure be aware of CFLAGS options starting with plus
4049 signs as it's the case for the HP/UX compiler.
4050 [Doug Yatcilla <yatcilda@umdnj.edu>] PR#3681
4052 *) Remove the hard-wire of TAR=tar (we now check for gtar and gnutar first)
4053 and check to see if the tar we wind up with supports '-h'.
4054 [Jim Jagielski] PR#3671
4056 *) A consistent and conservative style for all shell scripts has been
4057 implemented. Basically, all shell string tests use the traditional
4058 hack of 'if [ "x$var" != "x" ]' or 'if [ "x$var" = "xstring" ]'
4059 to protect against bare null variable strings (ie: wrapping both
4060 sides with double quotes and prepending 'x'). 'x' was chosen
4061 because it's more universal and hopefully easier for old shell
4062 prgrammers, as well as being easier to search for in 'vi' (/x\$) :)
4065 *) The status module now prints out both the main server generation as
4066 well as the generation of each process. Also, the vhost info is
4067 printed with '?notable'. [Jim Jagielski]
4069 *) Move src/main/md5c.c to src/ap/ap_md5c.c; it's httpd-neutral
4070 and this makes its functions available to things in src/support.
4073 Changes with Apache 1.3.4
4075 *) Renamed macros status_drops_connection to ap_status_drops_connection
4076 and vestigial scan_script_header to ap_scan_script_header_err,
4077 mostly for aesthetic reasons. [Roy Fielding]
4079 *) The query switch "httpd -S" didn't exit after showing the
4080 vhost settings. That was inconsistent with the other query functions.
4083 *) Moved the MODULE_MAGIC_COOKIE from before the versions and
4084 filename to the end of the STANDARD_MODULE_STUFF. Its
4085 presence at the beginning prevented reporting of the filename
4086 for modules compiled before 1 January 1999. [Ken Coar]
4088 *) SECURITY: ap_os_is_filename_valid() has been added to Win32
4089 to detect and prevent access to special DOS device file names.
4090 [Paul Sutton, Ken Parzygnat]
4092 *) WIN32: Created new makefiles Makefile_win32.txt (normal build)
4093 and Makefile_win32_debug.txt (debug build) that work on Win95.
4094 Run each of the following from the src directory:
4095 nmake /f Makefile_win32.txt # compiles normal build
4096 nmake /f Makefile_win32.txt install # compiles and installs
4097 nmake /f Makefile_win32.txt clean # removes compiled junk
4098 nmake /f Makefile_win32_debug.txt # compiles debug build
4099 nmake /f Makefile_win32_debug.txt install
4100 nmake /f Makefile_win32_debug.txt clean
4103 *) Added binbuild.sh and findprg.sh helpers to make it easier for us
4104 to build binary distributions. [Lars Eilebrecht]
4106 *) IndexOptions SuppressColumnSorting only turned off making
4107 the column headers anchors; you could still change the display
4108 order by manually adding a '?N=A' or similar query string to the
4109 URL. Now SuppressColumnSorting locks in the sort order so
4110 it can't be overridden this way. [Ken Coar]
4112 *) Added IndexOrderDefault directive to supply a default sort order
4113 for FancyIndexed directory listings. [Ken Coar] PR#1699
4115 *) Change the ap_assert macro to a variant that works on all platforms.
4116 [Richard Prinz <richard.prinz@cso.net>] PR#2575
4118 *) Make sure under ELF-based NetBSD (now) and OpenBSD (future) we don't
4119 search for an underscore on dlsym() (as it's already the case
4120 for FreeBSD 3.0). [Todd Vierling <tv@pobox.com>] PR#2462
4122 *) Small fix for mod_env.html: The module was documented as to be _not_
4123 compiled into Apache per default, although it _IS_ compiled into
4124 Apache per default. [Sim Harbert <sim@mindspring.com>] PR#3572
4126 *) Instead of fixing a bug in the generation procedure for config.status (a
4127 backslash was missing) we remove the bug together with it's complete
4128 context because the special cases of the past can now no longer occur
4129 because of the recent magic for the --with-layout default.
4130 [Ralf S. Engelschall] PR#3590
4132 *) Make top-level Makefile aware of a parallel build procedures (make -j) by
4133 making sure the src/support/ tools are _forced_ to be build last (they
4134 depend on other libraries).
4135 [Markus Theissinger <markus.theissinger@gmx.de>]
4137 *) Fix installation procedure: Now that os-inline.c is actually used (a
4138 recently fixed bug prevented this) we need to also install os-include.c
4139 in addition to os.h into the PREFIX/include/ location or building of
4140 module DSOs with APXS fails. [Ralf S. Engelschall] PR#3527
4142 *) Added MODULE_MAGIC_COOKIE as the first field in a module structure to
4143 allow us to distinguish between a garbled DSO (or even a file which isn't
4144 an Apache module DSO at all) and a DSO which doesn't match the current
4145 Apache API. [Ralf S. Engelschall] PR#3152
4147 *) Two minor enhancements to mod_rewrite: First RewriteRule now also
4148 supports the ``nocase|NC'' flag (as RewriteCond already does for ages) to
4149 match case insensitive (this especially avoids nasty patterns like
4150 `[tT][eE][sS][tT]'). Second two additional internal map functions
4151 `escape' and `unescape' were added which can be used to escape/unescape
4152 to/from hex-encodings in URLs parts (this is especially useful in
4153 combination with map lookups).
4154 [Magnus Bodin, Ian Kallen, Ralf S. Engelschall]
4156 *) Renamed the macro escape_uri() to ap_escape_uri() which was
4157 forgotten (because it was a macro) in the symbol renaming process.
4158 [Ralf S. Engelschall]
4160 *) Fix some inconsistencies related to the scopes of directives. The only
4161 user visible change is that the directives `UseCanonicalName' and
4162 `ContentDigest' now use the (more correct) `Options' scope instead of
4163 (less correct) `AuthConfig' scope. [Ralf S. Engelschall]
4165 *) Using DSO, the Server token was being mangled. Specifically, the
4166 module's token was being added first before the Apache token. This
4167 has been fixed. [Jim Jagielski]
4169 *) Major overhaul of mod_negotiation.c, part 2.
4170 - properly handle "identity" within Accept-Encoding.
4171 - allow encoded variants in RVSA negotiation and let them appear in
4172 the Alternates field using the non-standard "encoding" tag-list.
4173 - fixed both negotiation algorithms so that an explicitly accepted
4174 encoding is preferred over no encoding if "identity" is not
4175 included within Accept-Encoding.
4176 - added ap_array_pstrcat() to alloc.c for efficient concatenation
4177 of large substring sequences.
4178 - replaced O(n^2) memory hogs in mod_negotiation with ap_array_pstrcat.
4181 *) Major overhaul of mod_negotiation.c, part 1.
4182 - cleanups to mod_negotiation comments and code structure
4183 - made compliant with HTTP/1.1 proposed standard (rfc2068) and added
4184 support for everything in the upcoming HTTP/1.1
4185 revision (draft-ietf-http-v11-spec-rev-06.txt).
4186 - language tag matching also handles tags with more than 2
4188 - empty Accept, Accept-Language, Accept-Charset headers are
4189 processed correctly; previously an empty header would make all
4190 values acceptable instead of unacceptable.
4191 - allowed for q values in Accept-Encoding
4192 - added support for transparent content negotiation (rfc2295 and
4193 rfc2296) (though we do not implement all features in these drafts,
4194 e.g. no feature negotiation). Removed old experimental version.
4195 - implemented 'structured entity tags' for better cache correctness
4196 (structured entity tags ensure that caches which can deal with Vary
4197 will (eventually) be updated if the set of variants on the server
4199 - this involved adding a vlist_validator element to request_rec
4200 - this involved adding the ap_make_etag() function to the global API
4201 - modified guessing of charsets used by Apache negotiation algorithm
4202 to guess 'no charset' if the variant is not a text/* type
4203 - added code to sort multiviews variants into a canonical order so that
4204 negotiation results are consistent across backup/restores and mirrors
4205 - removed possibility of a type map file resolving to another type map
4206 file as its best variant
4207 [Koen Holtman, Roy Fielding, Lars Eilebrecht] PR#3451, 3299, 1987
4209 *) RFC2396 allows the syntax http://host:/path (with no port number)

4217 *) Correct some filename case assumptions from WIN32 to
4218 CASE_BLIND_FILESYSTEM. [Brian Havard <brianh@kheldar.apana.org.au>]
4220 *) For %v log ServerName regardless of the UseCanonicalName
4221 setting (similarly for %p). [Dean Gaudet]
4223 *) Configure was initializing the variables $OSDIR, $INCDIR and $SHELL
4224 rather late (too late for some invocations of TestCompile).
4225 This improves the make environment available to TestCompile and
4226 the *.module scripts. [Martin Kraemer]
4228 *) The hashbang emulation code in ap_execve.c would interpret
4229 #!/hashbang/scripts correctly, but failed to fall back to a
4230 standard shell for scripts which did NOT start with #!
4231 Now SHELL_PATH is started in these cases. [Martin Kraemer]
4233 *) PORT: Added the Cyberguard V2 port [Richard Stagg <stagg@lentil.org>]
4236 *) Update APXS manual page: some -q option arguments were missing
4237 and another was incorrect. [Mark Anderson <mda@discerning.com>] PR#3553
4239 *) Cleanup the command line options: `-?' was documented to show
4240 the usage list but does it with an error because `?' is not a valid
4241 command. OTOH a lot of users expect `-h' to print such a usage list and
4242 instead are annoyed for ages by our huge unreadable list of directives.
4243 So we now changed the command line options this way:
4245 Intent: we need `-L' to be free, and `-R' for the DSO run-time path is
4246 very similar to the popular linker option.
4248 Intent: while -l gives the small list of modules, -L now gives the
4249 large list of directives implemented by these modules. This is also
4250 consistent with -v (short version info) and -V (large version info).
4252 Intent: it's now the expected option ;-)
4253 The manual page was adjusted accordingly.
4254 [Ralf S. Engelschall] PR#2714
4256 *) Fixed problem of fclose() on an unopened file in suexec if LOG_EXEC
4257 wasn't defined. [Rick Franchuk <rickf@transpect.net>]
4259 *) Removed recently introduced bugs and disfigurements in APACI:
4260 o fixed argument line processing: using $args was broken: It was not
4261 initialized and using args="$args $apc_option" and even args="$args
4262 \"$apc_option\"" fails in the second processing round for any arguments
4263 containing whitespaces. The only correct way is to use the construct
4264 "$@" (but not possible here) or iterate _both_ times over the implicit
4265 argument line (no argument to for-loop) which is what we now use.
4266 o make --with-layout=Apache the default without creating
4267 redundancy (copying the --with-layout block in the argument parsing
4268 loop). We achieve this by using the "$@" construct together with the
4269 `set' command to prepend --with-layout=Apache to the command line in
4270 case --with-layout is not used.
4271 o fixed auto-suffix handling now that config.layout exists.
4272 Paths which are auto-suffixed are marked with a trailing plus sign in
4273 config.layout and every path now can be marked this way (not only the
4274 four paths for which we do it currently). Additionally the suffix is
4275 no longer a static one. Instead it's now `/<target>' where <target> is
4276 the argument of the --target option or per default `httpd'.
4277 o allow also tabs (and only spaces) where we match whitespaces
4278 o various fixes and cleanups related to used shell coding style
4279 o made Jim happy by replacing `Written by' with `Initially written by' ;-)
4280 o trimmed output of --help to fit into 80 columns
4281 [Ralf S. Engelschall]
4283 *) Added two new core API functions, ap_single_module_configure() and
4284 ap_single_module_init(), which are now used by mod_so to configure a module
4285 after loading. [Ralf S. Engelschall]
4287 *) PORT: Add defines for USE_FLOCK_SERIALIZED_ACCEPT and
4288 SINGLE_LISTEN_UNSERIALIZED_ACCEPT to NetBSD/OpenBSD section
4289 of ap_config.h to allow serialized accept for multiport listens.
4290 [Roy Fielding, Curt Sampson] PR#3120
4292 *) PORT: Fixed a misplaced #endif for NetBSD/OpenBSD section
4293 of ap_config.h that would skip several defines if DEFAULT_GROUP
4294 was overridden. [Roy Fielding]
4296 *) PORT: The I86 version of DGUX has support for strncasecmp and
4297 strcasecmp, so allow it in ap_config.h. [Amiel Lee Yee] PR#3247
4299 *) Fix ordering of definitions in ap_config.h so that ap_inline is
4300 defined before it might be used. [Victor Khimenko]
4302 *) PORT: Add Dynamic Shared Object (DSO) support for BSDI (v4.0).
4303 [Tom Serkowski <tks@bsdi.com>] PR#3453
4305 *) Make generation of src/Configuration.apaci more robust: It failed to
4306 differenciate between modules when one module name was a postfix of
4307 another (e.g. cgi vs. fastcgi). We now check for mod_XXX, libXXX and even
4308 just XXX (think about totally non-standard names like "apache_ssl", too).
4309 [Ralf S. Engelschall] PR#3380
4311 *) In src/Configure remove the SERVER_SUBVERSION support (already deprecated
4312 since 1.3b7) and make whitespace handling more robust (it failed horrible
4313 when whitespaces were present in the arguments of -D options).
4314 [Ralf S. Engelschall] PR#3240
4316 *) Add APACI --shadow=DIR variant (in addition to --shadow). This now first
4317 creates an external package shadow tree in DIR before the local build
4318 shadow tree is generated under DIR. This way one can have the extracted
4319 Apache distribution tree read-only on NFS or CDROM and still build Apache
4320 from these sources. An automatically triggered VPATH-like mechanism is
4321 provided through the TOP variable, too.
4322 [Ralf S. Engelschall, Wilfredo Sanchez <wsanchez@apple.com>]
4324 *) Fix negotiation so that a Vary response header is correctly
4325 generated when, for a particular dimension, variants only vary
4326 in having or not having a value for that dimension. [Paul Sutton]
4328 *) Fix negotiation so that we prefer an encoded variant over an
4329 unencoded variant if the user-agent explicitly says it can
4330 accept that encoding. Previously we always preferred the unencoded
4332 [Paul Ausbeck <paula@alumni.cse.ucsc.edu>, Paul Sutton] PR#3447
4334 *) Fix APXS tool: query variables LIBS_SHLIB and TARGET were not recognized
4335 and the usage page was inconsistent with the functionality and manpage.
4336 [Ralf S. Engelschall]
4338 *) Allow special options -Wc,xxx and -Wl,xxx on APXS compile/link command.
4339 They can occur multiple times and their arguments (`xxx') are passed AS
4340 IS to the compiler/linker command. [Ralf S. Engelschall]
4342 *) Fixed possible (but harmless in practice) bug in the DBM lookup
4343 procedure of mod_rewrite: very long keys were truncated.
4344 [Ralf S. Engelschall]
4346 *) Added a generic --with-layout=[FILE:]ID option. ID here is a layout
4347 identifier, currently "Apache" and "GNU" are pre-defined in the file
4348 config.layout. Custom layouts are possible by using FILE:ID as the
4349 argument where the layout ID is taken from FILE.
4351 The config.layout file consists of <Layout ID>..</Layout> sections
4352 where inside those sections "path_variable: path_value" pairs can be
4353 specified. These lines are converted to path_variable='path_value'.
4355 *) Add a DefaultLanguage directive so that files missing a language
4356 extension (e.g., .fr, .de) can be labelled as being some other
4357 default language. DefaultLanguage can appear in <Directory> and
4358 <Files> containers as well as .htaccess files. [Paul Sutton]
4361 *) Fix TARGET configuration when configuring and installing using
4362 APACI configure. TARGET now defines the basename of the configuration
4363 file, startup script, manual page, etc. log_error_core() now reports
4364 the server binary name given by argv[0]. TARGET can now also be defined
4365 with --target=TARGET parameter passed to APACI configure.
4366 [Ralf Engelschall, Randy Terbush]
4368 *) mod_include.c:handle_perl() now properly tests for OPT_INCNOEXEC
4369 rather than OPT_INCLUDES [Rainer Schoepf <schoepf@uni-mainz.de>]

4438 <Tom.Horsley@mail.ccur.com>]
4440 *) WIN32: Log more explicit error messages if spawning an interpreted
4441 script failed, including the command line used to attempt to execute
4442 the interpreter and the Win32 error code returned. [Marc Slemko]
4444 *) Disable sending of error-notes on a 500 (Internal Server Error) response
4445 since it often includes file path info. Enable sending of error-notes
4446 on a 501 (Method Not Implemented). [Roy Fielding] PR#3173
4448 *) http_config.c would respond with 501 (Method Not Implemented) if a
4449 content type handler was specified but could not be found, which
4450 should have been a 500 response. Likewise, mod_proxy.c would responsd
4451 with a 501 if the URI scheme is unrecognized instead of the correct
4452 response of 403 (Forbidden). [Roy Fielding]
4454 *) SECURITY: Eliminate DoS attack when a bad URI path contains what
4455 looks like a printf format escape. [Marc Slemko, Studenten Net Twente]
4457 *) Fix in mod_autoindex: for files where the last modified time stamp was
4458 unavailable, an empty string was printed which was 2 bytes short.
4459 The size and description columns were therefore not aligned correctly.
4460 [Martin Kraemer] (no PR#)
4462 *) Update BS2000 OS code to work with recent versions. Starting with
4463 release A17, the child fork() must be replaced by a _rfork().
4464 (BS2000 only) [Martin Kraemer]
4466 *) Add the actual server_rec structure of the specific Vhost to the
4467 scoreboard file and avoid a string copy (as well as allow some
4468 further future enhancements). [Harrie Hazewinkel
4469 <harrie.hazewinkel@jrc.it>]
4471 *) Add APACI --permute-module=foo:bar option which can be used to
4472 on-the-fly/batch permute the order of two modules (mod_foo and mod_bar)
4473 in the Configuration[.apaci] file. Two special and important variants are
4474 supported for the option argument: first BEGIN:foo which permutes module
4475 mod_foo with the begin of the module list, i.e. it `moves' the module to
4476 the begin of the list (gives it lowest priority). And second foo:END
4477 which permutes mod_foo with the end of the module list, i.e. it `moves'
4478 the module to the end of the list (gives it highest priority).
4479 [Ralf S. Engelschall]
4481 *) Fix problem with 'apache -k shutdown' and startup event
4482 synchronisation (Win32). [Ken Parzygnat <kparz@raleigh.ibm.com>]
4485 *) The config parser wasn't correctly noticing a missing '>'
4486 on container start lines (e.g., it wouldn't spot
4487 "<Directory /" as a syntax error). [Ryan Bloom <rbbloom@us.ibm.com>]
4490 *) Add a 'RemoveHandler' directive which will selectively remove
4491 all handler associations for the specified file extensions.
4492 [Ryan Bloom <rbbloom@us.ibm.com>] PR#1799.
4494 *) Properly handle & allow "nul" and ".*/null" in AccessConfig and
4495 ResourceConfig directives on Win32. Also add a note to the effect
4496 of 'useless User directive ignored on Win32' to the errorlog if
4497 a User directive is encountered on Win32.
4498 [Ken Parzygnat <kparz@raleigh.ibm.com>] PR#2078, 2303.
4500 *) Fix multiple whitespace handling in imagemaps for mod_imap which was
4501 broken since Apache 1.3.1 where we took out compressing of multiple
4502 spaces in ap_cfg_getline().
4503 [Ivan Richwalski <ivan@seppuku.net>] PR#3249
4505 *) Fix Berkeley-DB/2.x support in mod_auth_db: The data structures were not
4506 initialized correctly and the db_open() call used an invalid mode
4507 parameter. [Ron Klatchko <ron@ckm.ucsf.edu>] PR#3171
4509 *) PORT: DSO support for UnixWare 7
4510 [Ralf S. Engelschall, Ron Record <rr@sco.com>]
4512 *) Merge the contents of the {srm,access}.conf-dist* files into the
4513 httpd.conf-dist* files. The srm and access files now contain
4514 only comments, and httpd.conf has all the combined contents in
4515 a rational order. [Ken Coar]
4517 *) PORT: DSO/ELF support for FreeBSD 3.0.
4518 [Ralf S. Engelschall, Dirk Froemberg <ibex@physik.TU-Berlin.DE>]
4520 *) Add a "default-handler" handler that calls the default_hander()
4521 function which is normally called for static content. This allows
4522 you to override a specific handler. [Marc Slemko]
4524 *) Further simplify checking for absolute paths by replacing an
4525 hard-coded syntax check with a call to a routine we already created to
4526 do this. [Ken Parzygnat <kparz@raleigh.ibm.com>] PR#2976, 3074
4528 *) Log an error if we encounter a malformed "require" directive
4529 in mod_auth if we know that we know that no other module can
4530 deal with it. [Marc Slemko]
4532 *) Remove ap_private_extern method of hiding conflicting symbols
4533 on the NEXT platform because it is not correct for all versions,
4534 and the versions for which it is correct are unknown.
4535 [Wilfredo Sanchez <wsanchez@apple.com>]
4537 *) Fix inheritance of IndexOptions NameWidth and remove unintended
4538 restriction on +NameWidth, +IconHeight, and +IconWidth. [Ken Coar]
4540 *) Fix per-directory config merging for cases in which a 500 error
4541 is encountered in an .htaccess file somewhere down the tree.
4544 *) Minor performance improvement to ap_escape_html(). [Roy Fielding]
4546 *) Fixed a segmentation violation in mod_proxy when a response is
4547 non-cachable. [Roy Fielding, traced by Doug Bloebaum]. PR#2950, 3056
4549 Changes with Apache 1.3.3
4551 *) Added a complete implementation of the Expect header field as
4552 specified in rev-05 of HTTP/1.1. Disabled the 100 Continue
4553 response when we already know the final status, which is mighty
4554 useful for PUT responses that result in 302 or 401. [Roy Fielding]
4556 *) Remove extra trailing whitespace from the getline results as part
4557 of the protocol processing, which is extra nice because it works
4558 between continuation lines, is almost no cost in the normal case
4559 of no extra whitespace, and saves memory. [Roy Fielding]
4561 *) Added new HTTP status codes and default response bodies from the
4562 revised HTTP/1.1 (307, 416, 417), WebDAV (102, 207, 422, 423), and
4563 HTTP Extension Framework (510) specifications. Did not add the
4564 WebDAV 424 and 425 codes because they are bogus. We don't use any
4565 of these codes yet, but they are now available to 3rd-party modules.
4568 *) Fix a possible race condition between timed-out requests and the
4569 ap_bhalfduplex select that might result in an infinite loop on
4570 platforms that do not validate the descriptor. [Roy Fielding]
4572 *) WIN32: Add "-k shutdown" and "-k restart" options to signal a
4573 running Apache server [Paul Sutton]
4575 *) Fix mod_autoindex bug where directories got a size of "0k" instead
4576 of "-". [Martin Plechsmid <plechsmi@karlin.mff.cuni.cz>, Marc Slemko]
4579 *) PORT: DRS 6000 machine. [Paul Debleecker <pdebleecker@jetair.be>]
4581 *) Add the server signature text (from the core ServerSignature directive)
4582 to the list of envariables available to scripts, SSI, and the like.
4585 *) PORT: Fix sys/resource.h handling for SCO 3.x platform.
4586 [M. Laak <maert@proinv.ee>] PR#3108
4588 *) Fallback from sysconf-based to plain HZ-based `ticks per second'
4589 calculation in mod_status for all systems which don't have POSIX
4590 sysconf() (like UTS 2.1) and not only for the NEXT platform.
4591 [Dave Dykstra <dwd@bell-labs.com>] PR#3055
4593 *) Fix `require ...' directive parsing in mod_auth, mod_auth_dbm and
4594 mod_auth_db by using ap_getword_white() (which uses ap_isspace())
4595 instead of ap_getword(..., ' ') (which parses only according to spaces
4596 but not tabs). [James Morris <jmorris@intercode.com.au>,

4599 *) Fix the SERVER_NAME variable under sub-request situations (where
4600 `UseCanonicalName off' is used) like CGI's called from SSI pages or
4601 RewriteCond variables by adopting r->hostname to sub-requests.

4623 working directory to fill in some blanks. [Ken Parzygnat
4624 <kparz@raleigh.ibm.com>] PR#3001

4635 enable merging of multiple IndexOptions directives. [Ken Coar]
4637 *) PORT: Allow GuessOS to recognize Unixware 7.0.1 [Steve Cameron
4638 <steve.cameron@compaq.com>]
4640 *) Reconstructed the loop through multiple htaccess file names so
4641 that missing files are not confused with unreadable files.
4644 *) The ap_pfopen and ap_pfdopen routines were failing to protect the
4645 errno on an error, which leads to one error being mistaken for
4646 another when reading non-existent .htaccess files.
4649 *) OS/2: The new header tests get things right, need to update
4650 ap_config.h. [Brian Havard]
4652 *) The Perl %ENV hash will now be setup by default when using the
4653 mod_include `perl' command [Doug MacEachern]

4667 Changes with Apache 1.3.2
4669 *) Fix bug in ap_remove_module(), which caused problems for dso's
4670 who were the top_module. [Doug MacEachern]
4672 *) Add support for Berkeley-DB/2.x (in addition to Berkeley-DB/1.x) to
4673 mod_auth_db to both be friendly to users who wants to use this version
4674 and to avoid problems under platforms where only version 2.x is present.
4675 [Dan Jacobowitz <drow@false.org>, Ralf S. Engelschall]
4677 *) When using ap_log_rerror(), make the error message available to the
4678 *ERROR_NOTES envariables by default. [Ken Coar]
4680 *) BS2000 platform only: get rid of the nasty BS2000AuthFile.
4681 You now must define a BS2000Account name for the server User.
4682 This has fewer security implications than the old approach.
4685 *) Fix SHARED_CORE feature for HPUX platform: We now use extension `.sl'
4686 instead of `.so' and `SHLIB_PATH' instead of `LD_LIBRARY_PATH' on this
4687 platform to make the braindead HPUX linker happy. Notice, for the module
4688 DSOs we don't have to use this, because these are loaded manually (and
4689 not via HPUX' dld). [Ralf S. Engelschall] PR#2905, PR#2968
4691 *) Remove 64 thread limit on Win32.
4692 [Bill Stoddard <stoddard@raleigh.ibm.com>]
4694 *) Remove redundant substitutions in top-level Makefile.tmpl.
4695 [Ralf S. Engelschall]
4697 *) Fix APACI's `Group' configuration adjustment - especially for Linux
4698 platforms where `nogroup' exists in /etc/group. [Ralf S. Engelschall]
4700 *) Make PrintPath work generically instead of having one version
4701 strictly for OS/2. [Jim Jagielski, Brian Havard]
4703 *) Fix the recently introduced C header file checking: We now use the C
4704 pre-processor pass only (and no longer the complete compiler pass) to
4705 determine whether a C header file exists or not. Because only this way
4706 we're safe against inter-header dependencies (which caused horrible
4707 portability problems). The only drawback is that we now have a CPP
4708 configuration variable which has to be determined first (we do a similar
4709 approach as GNU Autoconf does here). When all fails the user still has
4710 the possibility to override it manually via APACI or src/Configuration.
4711 As a fallback for the header check itself we can directly check the
4712 existance of the file under /usr/include, too.
4713 [Ralf S. Engelschall] PR#2777
4715 *) PORT: Added RHAPSODY (Mac OS X Server) support. MAP_TMPFILE defined
4716 as an alternate mechanism for mmap'd shared memory for RHAPSODY.
4717 ap_private_extern defined to hide symbols that conflict with loaded
4718 dynamic libraries on the NEXT and RHAPSODY platforms.

4737 used -lprot. It's actually a bug in SCO5, of course.
4738 [Ronald Record <rr@sco.com>] PR#2533
4740 *) Fix documentation of ProxyPass/ProxyPassReverse according to the
4741 trailing slash problem. [Jon Drukman <jsd@gamespot.com>] PR#2933
4743 *) Remove `-msym' option from LDFLAGS_SHLIB for the Digital UNIX (OSF/1)
4744 platform, because it's only supported under version 4.0 and higher. But
4745 because our GuessOS is still unaware of Digital UNIX versions and the
4746 -msym is just to optimize the DSO statup time a little bit it's safe and
4747 best when we leave it out now. [Ralf S. Engelschall] PR#2969
4749 *) Fix the ap_log_error_old(), ap_log_unixerr() and ap_log_printf()
4750 functions: First all three functions no longer fail on strings containing
4751 "%" chars and second ap_log_printf() no longer does a double-formatting
4752 (instead it directly passes through the message to be formatted to the
4753 real internal formatting function). [Ralf S. Engelschall] PR#2941
4755 *) Allow "Include" directives anywhere in the server config
4756 files (but not .htaccess files). [Ken Coar] PR#2727
4758 *) The proxy was refusing to serve CONNECT requests except to
4759 port 443 (https://) and 563 (snews://). The new AllowCONNECT
4760 directive allows the configuration of the ports to which a
4761 CONNECT is allowed. [Sameer Parekh, Martin Kraemer]
4763 *) mod_expires will now act on content that is not sent from a file
4764 on disk. Previously it would never add an Expires: header to
4765 any response that did not come from a file on disk; the only
4766 case where it still doesn't (and can't) add one for that type of
4767 content is if you are using a modification date based setting.
4768 [Marc Slemko, Paul Phillips <paulp@go2net.com>]
4770 *) Problems encountered during .htaccess parsing or CGI execution
4771 that lead to a "500 Server Error" condition now provide explanatory
4772 text (in the *ERROR_NOTES envariable) to ErrorDocument 500 scripts.
4775 *) Add NameWidth keyword to IndexOptions directive so that the
4776 width of the filename column is customisable. [Ken Coar, Dean Gaudet]
4779 *) Recognize lowercase _and_ uppercase `uname' results under
4780 SCO OpenServer. [David Coelho <drc@ppt.com>]
4782 *) As duplicate "HTTP/1.0 200 OK" lines within the header seem to be
4783 a common problem of (mis-administrated?) IIS servers, make the apache
4784 proxy immune to these errors (and ignore the duplicates, but log
4785 the fact to error_log). [Martin Kraemer], after the proposal in PR#2914
4787 *) The <IfModule and <IfDefine block starting directives now only
4788 allow exactly one argument. Previously, the optional negation
4789 character '!' could be separated by whitespace without a syntax
4790 error being reported, albeit defeating the IfModule functionality
4791 (enclosed directives would ALWAYS be executed). By using the
4792 stricter syntax, these hard-to-track errors can be avoided.
4795 *) Simplify handling of IndexOptions in mod_autoindex -- and BTW
4796 cause the standalone FancyIndexing directive to logically OR
4797 into any existing IndexOptions settings rather than wiping
4798 them out. [Ken Coar]
4800 *) Changes in ftp proxy: make URL parsing simpler by using the
4802 + Add display of the "current directory" in cases where it's
4803 different from the supplied path (e.g., ftp://user@host/ lives
4804 in /home/user, not in /, therefore clicking on "../" in the
4805 starting directory might send us to /home/).
4806 + When ftp login fails, (esp. when a user name was part of the
4807 URL already), we now return [401 Unauthorized ] to allow the
4808 browser to pop up an authorization dialog. This makes passwords
4809 slightly less visible (they don't appear in the regular log files)
4810 and implements a functionality that other www proxy servers
4814 *) Triggered by the recent "Via:" header changes, the proxy module would
4815 dump core for replies with invalid headers (e.g., duplicate
4816 "HTTP/1.0 200 OK" lines). These errors are now logged and the
4817 core dump is avoided. Also, broken replies are not cached.
4818 [Martin Kraemer] PR#2914
4820 *) new `GprofDir' directive when compiled with -DGPROF, where gprof can
4821 plop gmon.out profile data for each child [Doug MacEachern]
4823 *) Use the construct ``"$@"'' instead of ``$*'' in the generated
4824 config.status script to be immune against arguments with whitespaces.
4825 [Yves Arrouye <yves@apple.com>] PR#2866
4827 *) Replace the inlined information grabbing stuff for the configuration
4828 adjustment feature (no --without-confadjust) with calls to a new helper
4829 script `buildinfo.sh' which is both more flexible and already proofed to
4830 be more robust against platform differences. This mainly fixes the
4831 recently occured ``sed: command garbled: ...'' problems.
4832 [Ralf S. Engelschall] PR#2776, PR#2848
4834 *) Make ab.c again pass ``gcc -Wall -Wshadow -Wpointer-arith -Wcast-align
4835 -Wmissing-prototypes -Wmissing-declarations -Wnested-externs -Winline''
4836 without complains after we recently added the POST feature.
4837 [Ralf S. Engelschall]
4839 *) Renamed is_HTTP_xxx() macros to ap_is_HTTP_xxx() name. They are used inside
4840 modules as API functions and we forgot them at the big symbol renaming.
4841 [Ralf S. Engelschall]
4843 *) Remove bad reference to non-existing SERVER_VERSION in mod_rewrite.html

4849 *) Add the ability to do POST requests to the ab benchmarking tool.
4850 [Kurt Sussman <kls@best.com>] PR#2871
4852 *) Bump up MAX_ENV_FLAGS in mod_rewrite.h from the too conservatice limit of
4853 5 to 10 because there are some users out there who always have 5 to 8
4854 variables in one RewriteRule and had to patch mod_rewrite.h for every
4855 release. So 15 should be now more than enough, even for them. (I never
4856 needed more than 4 in my RewriteRules ;-)
4857 [Ralf S. Engelschall]
4859 *) Make the proxy generate and understand Via: headers
4862 *) Change the proxy to use tables instead of array_headers for
4863 the header lines. [Martin Kraemer]
4865 *) Make sure the config.status file is not overridden when just
4866 ``configure --help'' is used. [Ralf S. Engelschall] PR#2844
4868 *) Split MODULE_MAGIC_NUMBER into _MAJOR/_MINOR numbers. This should
4869 provide a way to trace API changes that add functionality but do
4870 not create a compatibility issue for precompiled modules, etc.
4871 See include/ap_mmn.h for more details. [Randy Terbush]
4873 *) Fix suexec installation under `make install root=xxx' situation.
4874 [Ralf S. Engelschall]
4876 *) Extend the output of the -V switch to include the paths of all
4877 compiled-in configuration files, if they were overridden at
4878 compile time, for least astonishment of the user.
4881 *) When READing a request in ExtendedStatus mode, the "old"
4882 vhost, request and client information is not displayed.
4885 *) STATUS is no longer available. Full status information now
4886 run-time configurable using the ExtendedStatus directive.
4889 *) SECURITY: Eliminate O(n^2) space DoS attacks (and other O(n^2)
4890 cpu time attacks) in header parsing. Add ap_overlap_tables(),
4891 a function which can be used to perform bulk update operations
4892 on tables in a more efficient manner. [Dean Gaudet]
4894 *) SECURITY: Added compile-time and configurable limits for
4895 various aspects of reading a client request to avoid some simple
4896 denial of service attacks, including limits on maximum request-line
4897 size (LimitRequestLine), number of header fields (LimitRequestFields),
4898 and size of any one header field (LimitRequestFieldsize). Also added
4899 a configurable directive LimitRequestBody for limiting the size of the
4900 request message body. [Roy Fielding]
4902 *) Make status module aware of DNS and logging states, even if
4903 STATUS not defined. [Jim Jagielski]
4905 *) Fix a problem with the new OS/2 mutexes. [Brian Havard]
4907 *) Enhance mod_speling so that CheckSpelling can be used in
4908 <Directory> containers and .htaccess files. [Ken Coar]
4910 *) API: new ap_custom_response() function for hooking into the
4911 ErrorDocument mechanism at runtime [Doug MacEachern]
4913 *) API: new ap_uuencode() function [Doug MacEachern]
4915 *) API: scan_script_header_err_core() now "public" and renamed
4916 ap_scan_script_header_err_core() [Doug MacEachern]
4918 *) The 'status' module will now show the process pid's and their
4919 state even without full STATUS accounting. [Jim Jagielski]
4921 *) Restore the client IP address to the error log messages, this
4922 was lost during the transition from 1.2 to 1.3. Add a new
4923 function ap_log_rerror() which takes a request_rec * and
4924 formats it appropriately. [Dean Gaudet] PR#2661
4926 *) Cure ap_cfg_getline() of its nasty habit of compressing internal
4927 whitespace in input lines -- including within quoted strings.
4929 but leading and trailing whitespace should continue to be
4930 stripped [Martin Kraemer]
4932 *) Cleanup of the PrintPath/PrintPathOS2 helper functions. Avoid
4933 the ugly use of an env. variable and use command-line args for
4934 alternate $PATH. Make more like advanced 'type's as well.
4937 *) The IRIXN32 Rule was being ignored. Configure now correctly adds

5266 than strcmp() to check for parent directory-ness of an entry. Oh, and
5267 make sure the parent directory (if displayed) is *always* listed first
5268 regardless of the sort key. Overall performance winnage should be good
5269 in CPU time, instruction cache, and memory usage, particularly for large

5279 *) Add httpd -t (test) option for running configuration syntax tests only.
5280 If something is broken it complains and exits with a return code
5281 non-equal to 0. This can be used manually by the user to check the Apache
5282 configuration after editing and is also automatically used by apachectl
5283 on (graceful) restart command to make sure Apache doesn't die on restarts
5284 because of a configuration which is now broken since the last (re)start.
5285 This way `apachectl restart' can be used inside cronjobs without having
5286 to expect Apache to be falling down. Additionally the httpd -t can be run

5431 programs: ap_spawn_child_err() is used and the Win32 case now uses
5432 CreateProcess() instead of a low-level execl() (which caused problems in
5433 the past under Win32).
5434 [Ralf S. Engelschall]
5436 *) A few cosmetics and trivial enhancements to APXS to make the
5437 generated Makefile more user friendly. [Ralf S. Engelschall]
5439 *) Proxy Fix: The proxy special failure routine ap_proxyerror()
5440 was updated to use the normal apache error processing, thereby allowing
5441 proxy errors to be treated by ErrorDocument's as well. For this
5442 purpose, a new module-to-core communication variable "error-notes"
5443 was introduced; the proxy (and possibly other modules) communicates
5444 its error text using this variable. Its content is copied to a new
5445 cgi-env-var REDIRECT_ERROR_NOTES for use by ErrorDocuments.
5446 The old proxy special error routine ap_proxy_log_uerror()
5447 was replaced by regular ap_log_error() calls, many messages were made
5449 [Martin Kraemer] PR#494, 1259
5451 *) SECURITY: A possible buffer overflow in the ftp proxy was fixed.
5454 *) Transform the configure message "You need root privileges for suEXEC"
5455 from a fatal error into a (more friendly) warning because the building
5456 ("make") of Apache we can allow, of course. Root privileges are needed
5457 only for the installation step ("make install"). So make sure the
5458 user is aware of this fact but let him proceed as long as he can.
5459 [Ralf S. Engelschall] PR#2288
5461 *) Renamed three more functions to common ap_ prefix which we missed at the
5462 Big Symbol Renaming because they're #defines and not real C functions:
5463 is_default_port(), default_port(), http_method().
5464 [Ralf S. Engelschall]
5466 *) A zero-length name after a $ in an SSI document should cause
5467 just the $ to be in the expansion. This was broken during the
5468 security fixes in 1.2.5. [Dean Gaudet] PR#1921, 2249
5470 *) Call ap_destroy_sub_req() in ap_add_cgi_vars() to reclaim some
5471 memory. [Rob Saccoccio <robs@InfiniteTechnology.com>] PR#2252
5473 *) Fix src/support/httpd.exp (DSO export file which is currently only
5474 used under AIX) because of recent changes to function names.
5475 [Ralf S. Engelschall]
5477 Changes with Apache 1.3b7
5479 *) Make sure a MIME-type can be forced via a RewriteRule even when no
5480 substitution takes place, for instance via the following rule:
5481 ``RewriteRule ^myscript$ - [T=application/x-httpd-cgi]'' This was often
5482 requested by users in the past to force a single script without a .cgi
5483 extension and outside any cgi-bin dirs to be executed as a CGI program.
5484 [Ralf S. Engelschall] PR#2254
5486 *) A fix for protocol issues surrounding 400, 408, and
5487 414 responses. [Ed Korthof]
5489 *) Ignore MaxRequestsPerChild on WIN32. [Brian Behlendorf]
5491 *) Fix discrepancy in proxy_ftp.c which was causing failures when
5492 trying to connect to certain ftpd's, such as anonftpd.
5493 [Rick Ohnemus <rick@ecompcon.com>]
5495 *) Make mod_rewrite use ap_open_piped_log() for RewriteLog directive's
5496 logfile instead of fiddling around itself with child spawning stuff.
5497 [Ralf S. Engelschall]
5499 *) Made RefererIgnore case-insensitive.
5501 *) Mod_log_agent, mod_log_referer now use ap_open_piped_log for piped logs.
5504 *) Replace use of spawn_child with ap_spawn_child_err_buff, to make everything
5505 "safe" under Win32. In: mod_include.c, mod_mime_magic.c
5508 *) Improve RFC1413 support. [Bob Beck <beck@bofh.ucs.ualberta.ca>]
5510 *) Fix support script `dbmmanage': It was unable to handle some sort
5511 of passwords, especially passwords with "0" chars.
5512 [Ralf S. Engelschall] PR#2242
5514 *) WIN32: Clicking on "Last Modified" in a fancy index caused a crash. Fixed.
5515 [Ben Laurie] PR#2238
5517 *) WIN32: CGIs could cause a hang (because of a deadlock in the standard C
5518 library), so CGI handling has been changed to use Win32 native handles
5519 instead of C file descriptors.
5520 [Ben Laurie and Bill Stoddard <wgstodda@us.ibm.com>] PR#1129, 1607
5522 *) The proxy cache would store an incorrect content-length in the cached
5523 file copy after a cache update. That resulted in repeated fetching
5524 of the original copy instead of using the cached copy.
5525 [Ernst Kloppenburg <kloppen@isr.uni-stuttgart.de>] PR#2094
5527 *) The Makefiles assumed that DSO files are build via $(LD). This
5528 is broken for two reasons: First we never defined at least LD=ld
5529 somewhere to make sure this works (it was silently assumed that most Make
5530 provide a built-in LD definition - ARGL!) and second using the generic LD
5531 variable is not the truth. Instead a special variable named LD_SHLIB is
5532 reasonable because although "ld" is usually the default, the command for
5533 building DSO files can be "libtool" or even "cc" on some systems.
5534 [Ralf S. Engelschall]
5536 *) Replace the AddVersionPlatform directive with ServerTokens which
5537 provides for more control over the format of the Server:
5538 header line. SERVER_SUBVERSION is no longer supported;
5539 all module should use the ap_add_version_component()
5540 API function instead. [Jim Jagielski]
5542 *) Support for the NCR MP/RAS 3.0
5543 [John Withers <withers@semi.kcsc.mwr.irs.gov>]
5545 *) The LDFLAGS_SHLIB_EXPORT variable of src/Configuration[.tmpl] was
5546 not retrieved in src/Configure and thus was not useable.
5547 [Ralf S. Engelschall]
5549 *) Various Makefile consistency cleanups:
5550 - make OSDIR also automatically be relative to src/ like INCDIR
5551 - SUBDIRS is now generated in src/Makefile only and not in
5552 Makefile.config because it is a local define for this location.
5553 - remove BROKEN_BPRINTF_FLAGS because is it no longer used inside
5554 any Makefile but make sure that at least the "-K inline" is kept in
5556 - update the "depend" targets in Makefile.tmpl files to use $(OSDIR), too.
5557 - updated the dependencies theirself
5558 - removed not existing SHLIB variable from "clean" targets
5559 - replaced SHLIB_OBJS/SHLIBS_OBJ consistently with OBJS_PIC because OBJS
5560 already exists and OBJS_PIC are also just plain objects and have not
5561 directly to do with "shared" things. The only difference is that they
5562 contain PIC. So OBJS_PIC is the more canonical name.
5563 - Updated the Makefile-dependency lines for OBJS_PIC
5564 - Removed the Makefile-dependency line in Configure to avoid double
5566 - replaced ugly xx-so.o/xx.so-o hack with a clean and consistent usage
5567 of xxx.lo as GNU libtool does with its PIC objects
5568 - reduce local complexity in modules Makefile.tmpl by moving the last
5569 existing target "depend" to the generation section in Configure, too.
5570 - removed the historical $(SPACER) which was used in the past together
5571 with BROKEN_BPRINTF_FLAGS to avoid zig-zags in the build process. This
5572 is no longer needed.
5573 - force the build and run of the gen_xxx programs under main/ as the
5574 first step before building the objects because it looks cleaner
5575 [Ralf S. Engelschall]
5577 *) WIN32: Make Win32 work again after the /dev/null DoS fix.
5580 *) WIN32: Check for buffer overflows in ap_os_canonical_filename.
5583 *) WIN32: Don't force ISAPI headers to finish with \n.
5584 [Jim Patterson <Jim.Patterson@Cognos.COM>, Ben Laurie] PR#2060
5586 *) When opening "configuration" files (like httpd.conf, htaccess
5587 and htpasswd), Apache will not allow them to be non-/dev/null
5588 device files. This closes a DoS hole. At the same time,
5589 we use ap_pfopen to open these files to handle timeouts.
5590 [Jim Jagielski, Martin Kraemer]
5592 *) Apache will now log the reason its httpd children exit if they exit
5593 due to an unexpected signal. (It requires a new porting define,
5594 SYS_SIGLIST, which if defined should point to a list of text
5595 descriptions of the signals available. See PORTING.) [Dean Gaudet]
5597 *) WIN32: chdir() doesn't make sense in a multithreaded environment
5598 like WIN32. Before, Win32 CGI's could have had sporadic failures
5599 if a chdir call from one thread was made between another chdir call
5600 and a spawn in another thread. So, for now don't chdir for CGI scripts
5601 in WIN32. The current CGI "spec" is unclear as to whether it's
5602 necessary. Long-term fix is to either serialize the chdir/spawn combo
5603 or use WIN32 native calls to spawn a process. This temp fix was
5604 necessary to remove this as a showstopper for 1.3's release.
5607 *) Cleanup the suEXEC support in APACI and make it more safe:
5608 1. Add big fat hint in INSTALL about risks and to read the
5609 htdocs/manual/suexec.html document before using the suexec-related
5611 2. Make sure the user has at least provided one --suexec-xxxx option
5612 (specifies suEXEC parameters) in addition to --enable-suexec option.
5613 If only --enable-suexec is given APACI stops with a hint to INSTALL
5614 and htdocs/manual/suexec.html documents.
5615 3. Provide two additional --suexec-xxxx options to make the suEXEC
5616 configuration complete (especially for package maintainers who else
5617 had to patch the source tree) by providing ways to configure minimal
5618 UID/GID and safe PATH, too.
5619 [Ralf S. Engelschall]
5621 *) Cleanup of the `configure --shadow' process:
5622 - make sure the configure script creates its temporary files in the
5623 shadow tree to avoid conflicts with parallel configure runs
5624 - removed unnecessary option "-r" from "rm" call for Makefiles
5625 - make sure the configure scripts creates the shadow-wrapper Makefile
5626 only when no shadow trees already exists
5627 - make sure "make distclean" removes the shadow-wrapper Makefile but only
5628 when no more shadow trees exists
5629 - overhauled mkshadow.sh script: now its more IFS-safe and approx. twice
5630 as fast (in the past it needed 70sec, now it runs just 38sec)
5631 - make sure CVS does not complain about the created files
5632 Makefille.<gnutriple> and directories src.<gnutriple>
5633 [Ralf S. Engelschall]
5635 *) Added the ap_add_version_component() API routine and the
5636 AddVersionPlatform core directive. The first allows modules to
5637 declare themselves in the Server response header field value,
5638 augmenting the SERVER_SUBVERSION define in the Configuration file
5639 with run-time settings (more useful in a loadable-module environment).
5640 AddVersionPlatform inserts a comment such as "(UNIX)" or "(Win32)"
5641 into the server version string. [Ken Coar] PR#2056
5643 *) Minor stability tweaks to avoid core dumps in ap_snprintf.
5646 *) Emit the "Accept-Range" header for the default handler.
5647 [Brian Behlendorf] PR#1464
5649 *) Add a note to httpd.conf-dist that apache will on some systems fail
5650 to start when the Group # is set to a negative or large positive value.
5653 *) Make sure the module execution order is correct even when some modules
5654 are loaded under runtime (`LoadModule') via the DSO mechanism:
5655 1. The list of loaded modules is now a dynamically allocated one
5656 and not the original statically list from modules.c
5657 2. The loaded modules are now correctly setup by LoadModule for
5658 later use by the AddModule command.
5659 3. When the DSO mechanism for modules is used APACI's `install'
5660 target now enables all created `LoadModule' lines per default because
5661 this is both already expected by the user _and_ needed to avoid
5662 confusion with the next point and reduces the Makefile.tmpl complexity
5663 4. When the DSO mechanism for modules is used, APACI's `install'
5664 target now additionally makes sure the module list is reconstructed
5665 via a complete `ClearModuleList+AddModule...' entry.
5666 5. The support tool `apxs' now also makes sure an AddModule command
5667 is added in addition to the LoadModule command.
5668 6. The modules.c generation was extended to now contain two
5669 comments to make sure no one is confused by the confusing terminology
5670 of loading/linking (we use load=link+load & link=activate instead of
5671 the obvious load=activate & link=link :-( )
5672 This way now there is no longer a difference under execution time between
5673 statically and dynamically linked modules.
5674 [Ralf S. Engelschall]
5676 *) Fix the generated mod_xxx.c from "apxs -g -f xxx" after the
5677 Big Symbol Renaming. [Ralf S. Engelschall]
5679 *) Add a comment to mod_example.c showing the format of a FLAG command
5682 *) Standardized the time format in mod_status to match that of other
5683 places in the code (e.g. DATE_GMT). PR#1551
5685 *) Fix handling of %Z in timefmt strings for those platforms with no time
5686 zone information in their tm struct. [Paul Eggert <eggert@twinsun.com>]
5689 *) Makes mod_rewrite, mod_log_config, mod_status and the ServerSignature
5690 feature compatible with 'UseCanonicalName off' by changing
5691 r->server->server_hostname to ap_get_server_name(). And I changed some
5692 functions which use r->server->port to use ap_get_server_port() instead,
5693 because if there's no Port directive in the config r->server->port is 0.
5696 *) get/set_module_config are trivial enough to be better off inline. Worth
5697 1.5% performance boost. [Dean Gaudet]
5699 *) Fix off-by-one error in ap_proxy_date_canon() in proxy_util.c
5700 when ensuring 'x' is at least 30-chars big. [Jim Jagielski,
5703 *) [BS2000 security] BS2000 needs an extra authentication to initialize
5704 the task environment to the unprivileged User id. Otherwise CGI scripts
5705 would have a way to gain super user access. [Martin Kraemer]
5707 *) Fix debug log messages for BS2000/OSD: instead of logging the whole
5708 absolute path, only log base name of logging source as is done
5709 in unix. [Martin Kraemer]
5711 *) Ronald Tschalaer's Accept-Encoding patch - preserve the "x-" in
5712 the encoding type from the Accept-Encoding header (if it's there)
5713 and use it in the response, as that's probably what it'll be expecting.
5714 [Ronald.Tschalaer@psi.ch]
5716 *) Fix to mod_alias: translate_alias_redir is dealing with
5717 a URI, not a filename, so the check for drive letters for win32
5718 and emx is not necessary. [Dean Gaudet]
5720 *) WIN32: Allow .cmd as an executable extension.
5721 [Kari Likovuori <Kari.Likovuori@mol.fi>] PR#2146
5723 *) Make Apache header files, and some variables, C++ friendly.
5724 [Michael Anderson's <mka@redes.int.com.mx>]
5726 *) Child processes can now "signal" (by exiting with a status
5727 of APEXIT_CHILDFATAL) the parent process to abort and
5728 shutdown the server if the error in the child process was
5729 fatal enough. [Jim Jagielski]
5731 *) mod_autoindex's find_itme() was sensitive to MIME type case.
5732 [Jim Jagielski] PR#2112
5734 *) Make sure the referer_log and agent_log entries in the default httpd.conf
5735 file are also adjusted for the actual relative installation paths.
5736 [Ralf S. Engelschall] PR#2175
5738 *) WIN32: Extensive overhaul of the way UNCs are handled. [Ben Laurie]
5740 *) WIN32: Make roots of filesystems (e.g. c:/) work. [Ben Laurie]
5743 *) PORT: Various porting changes to support AIX 3.2, 4.1.5, 4.2 and 4.3.
5744 Additionally the checks for finding the vendor DSO library were moved
5745 from mod_so.c to Configure because first it needs $PLAT etc. and second
5746 mod_so already uses an abstraction layer and does not fiddle with the
5747 vendor functions itself.
5748 [Jens-Uwe Mager, Ralf S. Engelschall]
5750 *) PORT: Some optimization defines for NetBSD
5751 [Jaromir Dolecek <dolecek@ics.muni.cz>] PR#2165
5753 *) PORT: Dynamic Shared Object (DSO) support for NetBSD.
5754 [Jaromir Dolecek <dolecek@ics.muni.cz>, Ralf S. Engelschall] PR#2158
5756 *) Add Dynamic Shared Object (DSO) support for AIX (at least 4.2 but older
5757 AIX variants should work fine, too. Even AIX 3.x should work). This is
5758 accomplished by using the free DSO emulation code from Jens-Uwe Mager
5759 which we put into a os/unix/os-dso-aix.c file.
5760 [Ralf S. Engelschall]
5762 *) PORT: Fix compiler warnings under AIX >= 4.2 where the manual pages imply
5763 that we should use NET_SIZE_T == int but the include files force size_t.
5764 [Ralf S. Engelschall]
5766 *) Fix two bugs in select() handling in http_main.c.
5769 *) Suppress "error(0)" messages for ap_log_error() when the APLOG_NOERRNO
5770 is unset (as it is in situations like timeouts) where it is unclear
5771 whether errno is set or not. [Martin Kraemer]
5773 *) Just having APACI's localstatedir is too general and not enough for most
5774 of the systems. 1.3b6 again required manual APACI patches by package
5775 maintainers from RedHat and FreeBSD because for their filesystem layout a
5776 little bit more flexibility in configuring the paths is needed. Hence we
5777 provide three additional configure options (--runtimedir, --logfiledir,
5778 --proxycachedir) which now can be used for more granular adjustments if
5779 --localstatedir is not enough to fit the particular needs. As a nice
5780 side-effect this reduces some subdir fiddling in configure+Makefile.tmpl.
5781 [Ralf S. Engelschall]
5783 *) Make the install root for "make install" in APACI's Makefile overrideable
5784 by package authors. This way we are even more friendly to package
5785 maintainers (especially Debian and RedHat) who build for the real prefix
5786 via "configure --prefix=/<real>" but use a different local prefix via
5787 "make root=/tmp/apache install" for rolling the package without bristling
5788 the target location on their system.
5789 [Ralf S. Engelschall]
5791 *) Workaround sed limitations in APACI's configure script by now
5792 substituting in chunks of 50 commands (because for instance HPUX's vendor
5793 sed has a limit of max. 98 commands)
5794 [Ralf S. Engelschall] PR#2136
5796 *) Adding SOCKS5 support and fixing existing SOCKS4 support.
5797 [Ralf S. Engelschall] PR#2140
5799 *) Manually fix some symbols which were not renamed to prefix ap_ in the BIG
5800 RENAMING process because they are defined as pre-processor macros instead
5801 of real functions: bputc, bgetc, piped_log_write_fd, piped_log_read_fd
5802 [Ralf S. Engelschall]
5804 *) Workaround braindead AWK's when generating ap_config.h: The split() and
5805 substr() functions cannot be nested under vendor AWK from Solaris 2.6.
5806 [Ralf S. Engelschall] PR#2139
5808 *) Various bugfixes and cleanups for the APACI configure script:
5809 o fix IFS handling for _nested_ situation
5810 o fix Perl interpreter search: take first one found instead of last one
5811 o fix DSO consistency check
5812 o print error messages to stderr instead of stdout
5813 o add install-quiet for --shadow situation to Makefile stub
5814 o reduce complexity by avoiding sed-hacks for rule and module list loops
5815 [Ralf S. Engelschall]
5817 *) Fix DEBUG_CGI situation in mod_cgi.c [David MacKenzie] PR#2114
5819 *) Make sure the input field separator (IFS) shell variable is explicitly
5820 initialized correctly before _every_ `for' loop and also restored after
5821 the loops. [Ralf S. Engelschall]
5823 *) Make sure that "make install" doesn't overwrite the `mime.types' and
5824 `magic' files from an existing Apache installation. Because people often
5825 customize these for own MIME and content types.
5826 [Ralf S. Engelschall]
5828 *) PORT: Dynamic Shared Object (DSO) support for OpenBSD 2.x
5829 [Peter Galbavy, Ralf S. Engelschall] PR#2109
5831 *) Fix the path to the ScoreBoardFile in the install-config target, too.
5832 [Ralf S. Engelschall] PR#2105
5834 *) Let "configure" clear out the users parameters (provided as shell
5835 variables) to avoid side-effects in "src/Configure" when the user
5836 exported them (which is not needed, but some users do it).
5837 [Ralf S. Engelschall] PR#2101
5839 *) Provide backward compatibility from some old src/Configuration.tmpl
5840 parameter names to the canonical Autoconf-style shell variable names. For
5841 instance CFLAGS vs. EXTRA_CFLAGS. The EXTRA_xxx variants are accepted now
5842 but a hint message is displayed. [Ralf S. Engelschall]
5844 *) Make sure that "make install" doesn't overwrite the DocumentRoot and
5845 CGI scripts from an existing Apache installation.
5846 [Ralf S. Engelschall, Jim Jagielski] PR#2084
5848 *) Make `configure --compat' more "compatible" by first
5849 let the libexecdir default to EPREFIX/libexec instead of EPREFIX/bin and
5850 second by making sure the "avoid-bristling-suffix" /apache is not
5851 appended to sysconfdir, datadir, localstatedir and includedir when
5852 --compat is used. [Ralf S. Engelschall, Lars Eilebrecht]
5854 *) NeXT required strdup() in support/logresolve.c
5855 [Francisco Tomei <fatomei@sandburg.unm.edu>] PR#2082
5857 *) AIX required sys/select.h in support/ab.c
5858 [Jens Schleusener <Jens.Schleusener@dlr.de>] PR#2081
5860 *) Fix the path to the MimeMagicFile in the install-config target, too.
5861 [Ralf S. Engelschall] PR#2089
5863 *) PORT: Added HP-UX 11 patches [Jeff Earickson <jaearick@colby.edu>]
5865 *) If you start apache with the -S command line option it will dump
5866 out the parsed vhost settings. This is useful for folks trying
5867 to figure out what is wrong with their vhost configuration.
5868 (Other dumps may be added in the future.) [Dean Gaudet]
5870 *) Add %pA, %pI, and %pp codes to ap_vformatter (and hence ap_bprintf,
5871 ap_snprintf, and ap_psprintf). See include/ap.h for docs.
5874 *) Because /usr/local/apache is the default prefix the ``configure
5875 --compat'' option no longer has to set prefix, again. This way the
5876 --compat option honors a leading --prefix option. [Lars Eilebrecht]
5878 *) PORT: Cast the first argument of dlopen() in ap_os_dso_load()
5879 to `char *' under OSF1 and FreeBSD 2.x where it is defined this way
5880 to avoid "discard const" warnings. [Ralf S. Engelschall]
5882 *) If a specific handler is set for a file yet the request still
5883 ends up being handled by the default handler, log an error
5884 message before handling it. This catches things such as trying
5885 to use SSIs without mod_include enabled. [Marc Slemko]
5887 *) Fix error logging for the startup case where ap_log_error() still uses
5888 stderr as the target. Now the default log level is honored here, too.
5889 [Ralf S. Engelschall]
5891 *) PORT: Make sure some AWK's don't fail in src/Configure with "string too
5892 long" errors when generating the MODULES entry for src/Makefile
5893 [Ben Hyde, Ralf S. Engelschall]
5895 *) Make sure src/Configure doesn't complain about the old directory
5896 /usr/local/etc/httpd/ when APACI is used. [Lars Eilebrecht]
5898 Changes with Apache 1.3b6
5900 *) PORT: Clean up warnings on Ultrix and HPUX. [Ben Hyde]
5902 *) Adding DSO support for the HP/UX platform by emulating the dlopen-style
5903 interface via the similar but proprietary HP/UX shl_xxx-style system
5904 calls. [Ralf S. Engelschall]
5906 *) PORT: Updated UnixWare 2.0.x and 2.1.x entries for DSO support and made
5907 APACI Makefile.tmpl "install" target more robust for sensible UnixWare
5908 Make. [Ralf S. Engelschall]
5910 *) ++++ THE BIG SYMBOL RENAMING ++++
5911 To avoid symbol clashes with third-party code compiled into the server,
5912 we globally applied the prefix "ap_" to the following classes of
5914 - Apache provided general functions (e.g., ap_cpystrn)
5915 - Public API functions (e.g., palloc, bgets)
5916 - Private functions which we can't make static (because of
5917 cross-object usage) but should be (e.g., new_connection)
5918 For backward source compatibility a new header file named compat.h was
5919 created which provides defines for the old symbol names and can be used
5920 by third-party module authors.
5923 *) Added dynamic shared object (DSO) support for SVR4-derivates: The
5924 problem under SVR4 is that there is no command flag to force the linker
5925 to export the global symbols of the httpd executable therewith they are
5926 available to the DSO's. Instead of problematic hacks like creating a
5927 dummy.so file (containing dummy references to all global symbols) the
5928 httpd binary is linked against, we use a clean trick stolen from Perl 5:
5929 Placing the Apache core code itself into a DSO library named libhttpd.so.
5930 This way the global symbols _HAVE_ to be exported and thus are available
5931 to any manually loaded DSO's under runtime. To reduce the impact to the
5932 user to null we go even further and create a stub httpd executable which
5933 automatically keeps track of the DSO library loading itself and thus
5934 hides the complete mechanism from the user. Although the generation of
5935 this DSO library is automatically triggered for platforms which
5936 essentially need it (mostly all SVR4-derivates) it can be also enabled
5937 manually via the Rule SHARED_CORE. This can be interesting in the future
5938 where we perhaps exploit this libhttpd.so mechanism for providing nifty
5939 features like graceful upgrades, or whatever.
5940 [Ralf S. Engelschall, Martin Kraemer]
5942 *) Build the libraries before building the rest of the tools. [Ben Hyde]
5944 *) Add "distclean" target to src/-Makefiles to provide "make distclean" also
5945 inside the src subtree (i.e. for non-APACI users). Following GNU Makefile
5946 conventions while "clean" removes only stuff created by "all" targets,
5947 "distclean" additionally removes the stuff from the configuration
5948 process. This way "make distclean" (hence the name) provides a fresh
5949 source tree as it was for distribution.
5950 [Ralf S. Engelschall]
5952 *) Allow top-level (APACI) Makefile to break on build errors
5953 the same way the src/ subtree Makefiles breaks on them by replacing the
5954 initial APACI sed-subdir-display-kludge with a more clean
5955 variable-passing-solution: variable SDP can optionally hold the subdir
5956 prefix which is consistently used for displaying the subdir movement.
5957 This way even the top-level Makefile can stop correctly on errors as the
5958 user expects. [Ralf S. Engelschall]
5960 *) Fixed ordering of argument checks for RewriteBase directive.
5961 [Todd Eigenschink <eigenstr@mixi.net>] PR#2045
5963 *) Change Win32 IS_MODULE to SHARED_MODULE to match Unix' method of
5964 indicating that a module is being compiled for dynamic loading. Also
5965 remove #define IS_MODULE from modules and add SHARED_MODULE define
5966 to the mak/dsp files. [Alexei Kosut]
5968 *) Reduce logging level of "normal" warning messages to APLOG_INFO,
5969 since we are now logging APLOG_WARNING by default. [Roy Fielding]
5971 *) PORT: OS/2 tweak to deal with multiple .exe targets. [Brian Havard]
5973 *) Add documentation file and src/Configuration.tmpl entry for the
5974 experimental mod_mmap_static module. Because although it is and marked as
5975 an experimental one it is distributed and thus should be documented and
5976 prepared for configuration the same way as all others modules.
5977 [Ralf S. Engelschall]
5979 *) Add query (-q) option to apxs support tool to be able to manually query
5980 specific settings from apxs. This is needed for instance when you
5981 manually want to access Apache's header files and you need to assemble
5982 the -I option. Now you can do -I`apxs -q INCLUDEDIR`.
5983 [Ralf S. Engelschall]
5985 *) Now src/Configure uses a fallback strategy for the shared object support
5986 on platforms where no explicit information is available: If a Perl
5987 installation exists we ask it about its shared object support and if it's
5988 the dlopen-style one we shamelessly guess the compiler and linker flags
5989 for creating shared objects from Perls knowledge. Of course, the user is
5990 warning about what we are doing and informed that he should send us
5991 the guessed flags when they work. [Ralf S. Engelschall]
5993 *) Provide APACI --without-support option to be able to disable the build
5994 and installation of the support tools from the src/support/ area.
5995 Although its useful to have these installed per default we should provide
5996 a way to compile and install without them for backward-compatibility.
5997 [Ralf S. Engelschall]
5999 *) Add of the new APache eXtenSion (apxs) support tool for building and
6000 installing modules into an _already installed_ Apache package through the
6001 dynamic shared object (DSO) mechanism [mod_so.c]. The trick here is that
6002 this approach actually doesn't need the Apache source tree. The
6003 (APACI-installed) server package is enough, because this now includes the
6004 Apache C header files (PREFIX/include) and the new APXS tool
6005 (SBINDIR/apxs). The intend is to provide a handy tool for third-party
6006 module authors to build their Apache modules _OUTSIDE_ the Apache source
6007 tree while avoiding them to fiddle around with the totally platform
6008 dependend way of compiling DSO files. The tool supports all ranges of
6009 modules, from trivial ones (single mod_foo.c) to complex ones (like PHP3
6010 which has a mod_php3.c plus a pre-built libmodphp3-so.a) and even can
6011 on-the-fly generate a minimalistic Makefile and sample module for the
6012 first step to provide both a quick success event and to demonstrate the
6013 APXS mechanism to module authors. [Ralf S. Engelschall]
6015 *) Fix core dumps in use of CONNECT in proxy.
6016 [Rainer.Scherg@rexroth.de] PR#1326, #1573, #1942
6018 *) Modify the log directives in httpd.conf-dist files to use CustomLog
6019 so that users have examples of how CustomLog can be used.
6022 *) Add the new Apache Autoconf-style Interface (APACI) for the top-level of
6023 the Apache distribution tree. Until Apache 1.3 there was no real
6024 out-of-the-box batch-capable build and installation procedure for the
6025 complete Apache package. This is now provided by a top-level "configure"
6026 script and a corresponding top-level "Makefile.tmpl" file. The goal is
6027 to provide a GNU Autoconf-style frontend which is capable to both drive
6028 the old src/Configure stuff in batch and additionally installs the
6029 package with a GNU-conforming directory layout. Any options from the old
6030 configuration scheme are available plus a lot of new options for flexibly
6031 customizing Apache. [Ralf S. Engelschall]
6033 *) The floating point ap_snprintf code wasn't threadsafe.
6034 Had to remove the HAVE_CVT macro in order to do threadsafe
6035 calling of the ?cvt() floating point routines. [Dean Gaudet]
6037 *) PORT: Add the SCO_SV port. [Jim Jagielski] PR#1962
6039 *) PORT: IRIX needs the -n32 flag iff using the 'cc' compiler
6040 [Jim Jagielski] PR#1901
6042 *) BUG: Configure was using TCC and CC inconsistently. Make sure
6043 Configure knows which CC we are using. [Jim Jagielski]
6045 *) "Options +Includes" wasn't correctly merged if "+IncludesNoExec"
6046 was defined in a parent directory. [Lars Eilebrecht]
6048 *) API: ap_snprintf() code mutated into ap_vformatter(), which is
6049 a generic printf-style routine that can call arbitrary output
6050 routines. Use this to replace http_bprintf.c. Add new routines
6051 psprintf(), pvsprintf() which allocate the exact amount of memory
6052 required for a string from a pool. Use psprintf() to clean up
6053 various bits of code which used ap_snprintf()/pstrdup().
6056 *) PORT: HAVE_SNPRINTF doesn't do anything any longer. This is because
6057 ap_snprintf() has different semantics and formatting codes than
6058 snprintf(). [Dean Gaudet]
6060 *) SIGXCPU and SIGXFSZ are now reset to SIG_DFL at boot-time. This
6061 is necessary on at least Solaris where the /etc/rc?.d scripts
6062 are run with these signals ignored, and "SIG_IGN" settings are
6063 maintained across exec().
6064 [Rein Tollevik <reint@sys.sol.no>] PR#2009
6066 *) Fix the check for symbolic links in ``RewriteCond ... -l'': stat() was
6067 used instead of lstat() and thus this flag didn't work as expected.

6070 *) Fix the proxy pass-through feature of mod_rewrite for the case of
6071 existing QUERY_STRING now that mod_proxy was recently changed because of
6072 the new URL parsing stuff. [Ralf S. Engelschall]
6074 *) A few changes to scoreboard definitions which helps gcc generate
6075 better code. [Dean Gaudet]
6077 *) ANSI C doesn't guarantee that "int foo : 2" in a structure will
6078 be a signed bitfield. So mark a few bitfields as signed to
6079 ensure correct code. [Dean Gaudet]
6081 *) The default for HostnameLookups was changed to Off, but there
6082 was a problem and it wasn't taking effect. [Dean Gaudet]
6084 *) PORT: Clean up undefined signals on some platforms (SCO, BeOS).
6087 *) After a SIGHUP the listening sockets in the parent weren't
6088 properly marked for closure on fork().
6089 [Jürgen Keil <jk@tools.de>] PR#2000
6091 *) Allow %2F in two situations: 1) it is in the query part of the URI,
6092 therefore not exposed to %2F -> '/' translations and 2) the request
6093 is a proxy request, so we're not dealing with a local resource anyway.
6094 Without this, the proxy would fail to work for any URL's with
6095 %2f in them (occurs quite often in
6096 http://.../cgi-bin/...?http%3A%2F%2F... references) [Martin Kraemer]
6098 *) Protect against FD_SETSIZE mismatches. [Dean Gaudet]
6100 *) Make the shared object compilation command more portable by avoiding
6101 the direct combination of `-c' & `-o' which is not honored by some
6102 compilers like UnixWare's cc. [Ralf S. Engelschall]
6104 *) WIN32: the proxy was creating filenames missing the last four
6105 characters. While this normally doesn't stop anything from
6106 working, it can result in extra collisions.
6107 [Tim Costello <tjcostel@socs.uts.edu.au>] PR#1890
6109 *) Now mod_proxy uses the response string (in addition to the response status
6110 code) from the already used FTP SIZE command to setup the Content-Length
6111 header if available. [Ralf S. Engelschall] PR#1183
6113 *) Reanimated the (still undocumented) proxy receive buffer size directive:
6114 Renamed from ReceiveBufferSize to ProxyReceiveBufferSize because the old
6115 name was really too generic, added documentation for this directive to
6116 the mod_proxy.html and corrected the hyperlink to it in the
6117 new_features_1.3.html document. [Ralf S. Engelschall] PR#1348
6119 *) Fix a bug in the src/helpers/fp2rp script and make it a little bit
6120 faster [Martin Kraemer]
6122 *) Make Configure die when you give it an unknown command switch.
6125 *) Add five new and fresh manpages for the support programs: dbmmanage.1,
6126 suexec.8, htdigest.1, rotatelogs.8 and logresolve.8. Now all up-to-date
6127 and per default compiled support programs have manual pages - just to
6128 document our stuff a little bit more and to be able to do really
6129 Unix-like installations ;-) [Ralf S. Engelschall]
6131 *) Major cleanups to the Configure script to make it and its generated
6132 Makefiles again readable and maintainable: add SRCDIR option, removed
6133 INCLUDES_DEPTH[0-2] kludge, cleanup of TARGET option, cleanup of
6134 generated sections, consequently added Makefile headers with inheritance
6135 information, added subdir movement messages for easier following where
6136 the build process currently stays (more verbose then standard Make, less
6137 verbose than GNU make), same style to comments in the Configure script,
6138 added Apache license header, fixed a few bugs, etc. [Ralf S. Engelschall]
6140 *) Add the new ApacheBench program "ab" to src/support/: This is derived
6141 from the ZeusBench benchmarking program and can be used to determine the
6142 response performance of an Apache installation. This version is
6143 officially licensed with Zeus Technology, Ltd. See the license agreement
6144 statements in <199803171224.NAA24547@en1.engelschall.com> in apache-core.
6145 [Ralf S. Engelschall]
6147 *) API: Various core functions that are definately not part of the API
6148 have been made static, and a few have been marked API_EXPORT. Still
6149 more have been marked CORE_EXPORT and are not intended for general
6150 use by modules. [Doug MacEachern, Dean Gaudet]
6152 *) mod_proxy was not clearing the Proxy-Connection header from
6153 requests; now it does. This did not violate any spec, however
6154 causes poor interactions when you are talking to remote proxies.
6155 [Marc Slemko] PR#1741
6157 *) Various cleanups to the command line interface and manual pages.
6158 [Ralf S. Engelschall]
6160 *) cfg_getline() was not properly handling lines that did not end
6161 with a line termination character. [Marc Slemko] PR#1869, 1909
6163 *) Performance tweak to mod_log_config. [Dmitry Khrustalev]
6165 *) Clean up some undocumented behavior of mod_setenvif related to
6166 "merging" two SetEnvIf directives when they match the same header
6167 and regex. Document that mod_setenvif will perform comparisons in
6168 the order they appear in the config file. Optimize mod_setenvif by
6169 doing more work at config time rather than at runtime.
6172 *) src/include/ap_config.h now wraps it's #define's with #ifndef/#endif's
6173 to allow for modules to overrule them and to reduce redefinition
6174 warnings [Jim Jagielski]
6176 *) [PORT] For A/UX change the OS-#define for -DAUX to -DAUX3.
6179 *) Making the hard-coded cross-module function call mime_find_ct() (from
6180 mod_proxy to mod_mime) obsolete by making sure the API hook for MIME type
6181 checking is really called even for proxy requests except for URLs with
6182 HTTP schemes (because there we can optimize by not running the type
6183 checking hooks due to the fact that the proxy gets the MIME Content-type
6184 from the remote host later). This change cleans up mod_mime by removing
6185 the ugly export kludge, makes the one-liner file mod_mime.h obsolete, and
6186 especially unbundles mod_proxy and mod_mime. This way they both now can
6187 be compiled as shared objects and are no longer tied together.
6188 [Ralf S. Engelschall]
6190 *) util.c cleanup and speedup. [Dean Gaudet]
6192 *) API: Clarification, pstrndup() will always copy n bytes of the source
6193 and NUL terminate at the (n+1)st byte. [Dean Gaudet]
6195 *) Mark module command_rec and handler_rec structures const so that they
6196 end up in the read-only data section (and are friendlier to systems
6197 that don't do optimistic memory allocation on fork()). [Dean Gaudet]
6199 *) Add check to the "Port" directive to make sure the specified
6200 port is in the appropriate range. [Ben Hyde]
6202 *) Performance improvements to invoke_handler().
6203 [Dmitry Khrustalev <dima@bog.msu.su>]
6205 *) Added support for building shared objects even for library-style modules
6206 (which are built from more than one object file). This now provides the
6207 ability to build mod_proxy as a shared object module. Additionally
6208 modules like mod_example are now also supported for shared object
6209 building because the generated Makefiles now no longer assume there is at
6210 least one statically linked module. [Ralf S. Engelschall]
6212 *) API: Clarify usage of content_type, handler, content_encoding,
6213 content_language and content_languages fields in request_rec. They
6214 must always be lowercased; and the strings pointed to shouldn't
6215 be modified (you must copy them to modify them). Fix a few bugs
6216 related to this. [Dean Gaudet]
6218 *) API: Clarification: except for RAW_ARGS, all command handlers can
6219 treat the char * parameters as permanent, and modifiable. There
6220 is no need to pstrdup() them. Clean up some needless pstrdup().
6223 *) Now mod_so keeps track of which module shared objects with which names
6224 are loaded and thus avoids multiple loading and unloading and irritating
6225 error_log messages. [Ralf S. Engelschall]
6227 *) Prior to the existence of mod_setenv it was necessary to tweak the TZ
6228 environment variable in the apache core. But that tweaking interferes
6229 with mod_setenv. So don't tweak if the user has specified an explicit
6230 TZ variable. [Jay Soffian <jay@cimedia.com>] PR#1888
6232 *) rputs() did not calculate r->sent_bodyct properly.
6233 [Siegmund Stirnweiss <siegst@kat.ina.de>] PR#1900
6235 *) The CGI spec says that REMOTE_HOST should be set to the remote hosts's

6237 it to the IP address when unavailable.
6238 [Tony Finch <fanf@demon.net>] PR#1925
6240 *) Various improvements to the configuration and build support for compiling
6241 modules as shared objects. Especially Solaris 2.x, SunOS 4.1, IRIX and
6242 OSF1 support with GCC and vendor compilers was added. This way shared
6243 object support is now provided out-of-the-box for FreeBSD, Linux,
6244 Solaris, SunOS, IRIX and OSF1. In short: On all major platforms!
6245 [Ralf S. Engelschall]
6247 *) Minor cleanup in http_main -- split QNX and OS2 specific "mmap"
6248 scoreboard code into separate #defines -- USE_POSIX_SCOREBOARD
6249 and USE_OS2_SCOREBOARD. [Dean Gaudet]
6251 *) Fix one more special locking problem for RewriteMap programs in
6252 mod_rewrite: According to the documentation of flock(), "Locks are on
6253 files, not file descriptors. That is, file descriptors duplicated
6254 through dup(2) or fork(2) do not result in multiple instances of a lock,
6255 but rather multiple references to a single lock. If a process holding a
6256 lock on a file forks and the child explicitly unlocks the file, the
6257 parent will lose its lock.". To overcome this we have to make sure the
6258 RewriteLock file is opened _AFTER_ the childs were spawned which is now
6259 the case by opening it in the child_init instead of the module_init API
6260 hook. [Ralf S. Engelschall] PR#1029
6262 *) Change to Location and LocationMatch semantics. LocationMatch no
6263 longer lets a single slash match multiple adjacent slashes in the
6264 URL. This change is for consistency with RewriteRule and
6265 AliasMatch. Multiple slashes have meaning in URLs that they do
6266 not have in (some) filesystems. Location on the other hand can
6267 be considered a shorthand for a more complicated regex, and it
6268 does match multiple slashes with a single slash -- which is
6269 also consistent with the Alias directive.

6272 *) Fix bug with mod_mime_magic causing certain files, including files
6273 of length 0, to result in no response from the server.
6276 *) The Configure script now generates src/include/ap_config.h which
6277 contains the set of defines used when Apache is compiled on a platform.
6278 This file can then be included by external modules before including
6279 any Apache header files in case they are being built separately from
6280 Apache. Along with this change, a couple of minor changes were
6281 made to make Apache's #defines coexist peacefully with any autoconf
6282 defines an external module might have. [Rasmus Lerdorf]
6284 *) Fix mod_rewrite for the ugly API case where <VirtualHost> sections exist
6285 but without any RewriteXXXXX directives. Here mod_rewrite is given no
6286 chance by the API to initialize its per-server configuration and thus
6287 receives the wrong one from the main server. This is now avoided by
6288 remembering the server together with the config structure while
6289 configuring and later assuming there is no config when we see a
6290 difference between the remembered server and the one calling us.
6291 [Ralf S. Engelschall] PR#1790
6293 *) Fixed the DBM RewriteMap support for mod_rewrite: First the support now
6294 is automatically disabled under configure time when the dbm_xxx functions
6295 are not available. Second, two heavy source code errors in the DBM
6296 support code were fixed. This makes DBM RewriteMap's usable again after
6297 a long time of brokenness. [Ralf S. Engelschall] PR#1696
6299 *) Now all configuration files support Unix-style line-continuation via
6300 the trailing backslash ("\") character. This enables us to write down
6301 complex or just very long directives in a more readable way. The
6302 backslash character has to be really the last character before the
6303 newline and it has not been prefixed by another (escaping) backslash.

6318 *) PORT: USE_PTHREAD_SERIALIZED_ACCEPT has proven unreliable
6319 depending on the rev of Solaris and what mixture of modules
6320 are in use. So it has been disabled, and Solaris is back to
6321 using USE_FCNTL_SERIALIZED_ACCEPT. Users may experiment with
6322 USE_PTHREAD_SERIALIZED_ACCEPT at their own risk, it may speed
6323 up static content only servers. Or it may fail unpredictably.

6326 *) mod_test_util_uri.c created which tests the logic in util_uri.c.
6329 *) API: Rewrite of absoluteURI handling, and in particular how
6330 absoluteURIs match vhosts. Unless a request is a proxy request, a
6331 "http://host" url is treated as if a similar "Host:" header had been
6332 supplied. This change was made to support future HTTP/1.x protocols
6333 which may require clients to send absoluteURIs for all requests.
6335 In order to achieve this change subtle changes were made to the API. In a
6336 request_rec, r->hostlen has been removed. r->unparsed_uri now exists so
6337 that the unmodified uri can be retrieved easily. r->proxyreq is not set
6338 by the core, modules must set it during the post_read_request or
6339 translate_names phase.
6341 Plus changes to the virtualhost test suite for absoluteURI testing.
6343 This fixes several bugs with the proxy proxying requests to vhosts
6344 managed by the same httpd.
6347 *) API: Cleanup of code in http_vhost.c, and remove vhost matching

6365 *) API: A new source module main/util_uri.c; It contains a routine
6366 parse_uri_components() and friends which breaks a URI into its component
6367 parts. These parts are stored in a uri_components structure called
6368 parsed_uri within each request_rec, and are available to all modules.
6369 Additionally, an unparse routine is supplied which re-assembles the URI
6370 components back to an URI, optionally hiding the username:password@ part
6371 from ftp proxy requests, and other useful routines. Within the structure,
6372 you find on a ready-for-use basis:
6373 scheme; /* scheme ("http"/"ftp"/...) */
6374 hostinfo; /* combined [user[:password]@]host[:port] */
6375 user; /* user name, as in http://user:passwd@host:port/ */
6376 password; /* password, as in http://user:passwd@host:port/ */
6377 hostname; /* hostname from URI (or from Host: header) */

6380 query; /* Everything after a '?' in the path, if present */
6381 fragment; /* Trailing "#fragment" string, if present */
6382 This is meant to serve as the platform for *BIG* savings in
6383 code complexity for the proxy module (and maybe the vhost logic).
6386 *) Make all possible meta-construct expansions ($N, %N, %{NAME} and

6403 *) Fix bug introduced in 1.3b4-dev, config with no Port setting would cause
6404 server to bind to port 0 rather than 80. [Dean Gaudet]
6406 *) Fix long-standing problem with RewriteMap _programs_ under Unix derivates
6407 (like SunOS and FreeBSD) which don't accept the locking of pipes
6408 directly. A new directive RewriteLock is introduced which can be used to
6409 setup a separate locking file which then is used for synchronization.

6412 *) WIN32: The server root is obtained from the registry key
6413 HKLM\SOFTWARE\Apache Group\Apache\<version> (version is currently

6415 value is stored by running "apache -i -d serverroot". [Paul Sutton]

6424 *) The mod_setenvif BrowserMatch backwards compatibility command did not
6425 work properly with spaces in the regex. [Ronald Tschalaer] PR#1825
6427 *) Add new RewriteMap types: First, `rnd' which is equivalent to the `txt'
6428 type but with a special post-processing for the looked-up value: It
6429 parses it into alternatives according to `|' chars and then only one
6430 particular alternative is chosen randomly (this is an essential
6431 functionality needed for balancing between backend-servers when using
6432 Apache as a Reverse Proxy. The looked up value here is a list of
6433 servers). Second, `int' with the built-in maps named `tolower' and
6434 `toupper' which can be used to map URL parts to a fixed case (this is an
6435 essential feature to fix the case of server names when doing mass
6436 virtual-hosting with the help of mod_rewrite instead of using
6437 <VirtualHost> sections). [Ralf S. Engelschall, parts based on code from
6438 Jay Soffian <jay@cimedia.com>] PR#1631
6440 *) Add a new directive to mod_proxy similar to ProxyPass: `ProxyPassReverse'.
6441 This directive lets Apache adjust the URL in Location-headers on HTTP
6442 redirect responses sent by the remote server. This way the virtually
6443 mapped area is no longer left on redirects and thus by-passed which is
6444 especially essential when running Apache as a reverse proxy.

6545 Changes with Apache 1.3b4
6547 *) The module structure was modified to include a *dynamic_load_handle
6548 in the STANDARD_MODULE_STUFF portion, and the MODULE_MAGIC_NUMBER
6549 has been bumped accordingly. [Paul Sutton]
6551 *) All BrowserMatch directives mentioned in
6552 htdocs/manual/known_client_problems.html are in the default
6553 configuration files. [Lars Eilebrecht]
6555 *) MiNT port update. [Jan Paul Schmidt]
6557 *) HTTP/1.1 requires x-gzip and gzip encodings be treated
6558 equivalent, similarly for x-compress and compress. Apache
6559 now ignores a leading x- when comparing encodings. It also
6560 preserves the encoding the client requests (for example if
6561 it requests x-gzip, then Apache will respond with x-gzip
6562 in the Content-Encoding header).
6563 [Ronald Tschalaer <Ronald.Tschalaer@psi.ch>] PR#1772
6565 *) Fix a memory leak on keep-alive connections. [Igor Tatarinov]
6567 *) Added mod_so module to support dynamic loading of modules on Unix
6568 (like mod_dld for Win32). This replaces mod_dld.c. Use SharedModule
6569 instead of AddModule in Configuration to build shared modules
6570 [Sameer Parekh, Paul Sutton]
6572 *) Minor cleanups to r->finfo handling in some modules.
6575 *) Abstract read()/write() to ap_read()/ap_write().
6576 Makes it easier to add other types of IO code such as SFIO.
6579 *) API: Generalize default_port manipulations to make support of
6580 different protocols easier. [Ben Laurie, Randy Terbush]
6582 *) There are many cases where users do not want Apache to form
6583 self-referential urls using the "canonical" ServerName and Port.
6584 The new UseCanonicalName directive (default on), if set to off
6585 will cause Apache to use the client-supplied hostname and port.
6586 API: Part of this change required a change to the construct_url()
6587 prototype; and the addition of get_server_name() and
6589 [Michael Douglass <mikedoug@texas.net>, Dean Gaudet]
6590 PR#315, 459, 485, 1433
6592 *) Yet another rearrangement of the source tree.. now all the common
6593 header files are in the src/include directory. The -Imain -Iap
6594 references in Makefiles have been changed to the simpler -Iinclude
6595 instead. In addition to simplifying the build a little bit, this
6596 also makes it clear when a module is referencing something in a
6597 other than kosher manner (e.g., the proxy including mod_mime.h).
6598 Module-private header files (the proxy, mod_mime, the regex library,
6599 and mod_rewrite) have not been moved to src/include; nor have
6600 the OS-abstraction files. [Ken Coar]
6602 *) Fix a bug where r->hostname didn't have the :port stripped
6603 from it. [Dean Gaudet]
6605 *) Tweaked the headers_out table size, and the subprocess_env
6606 table size guess in rename_original_environment(). Added
6607 MAKE_TABLE_PROFILE which can help discover make_table()
6608 calls that use too small an initial guess, see alloc.c.
6611 *) Options and AllowOverride weren't properly merging in the main
6612 server setting inside vhosts (only an issue when you have no
6613 <Directory> or other section containing an Options that affects
6614 a request). Options +foo or -foo in the main_server wouldn't
6615 affect the main_server's lookup defaults. [Dean Gaudet]
6617 *) Variable 'cwd' was being used pointlessly before being set.
6620 *) r->allowed handling cleaned up in the standard modules.
6623 *) Some case-sensitivity issues cleaned up to be consistent with
6624 RFC2068. [Dean Gaudet]
6626 *) SIGURG doesn't exist everywhere.
6627 [Mark Andrew Heinrich <heinrich@tinderbox.Stanford.EDU>]
6629 *) mod_unique_id was erroneously generating a second unique id when
6630 an internal redirect occured. Such redirects occur, for example,
6631 when processing a DirectoryIndex match. [Dean Gaudet]
6633 *) API: table_add, table_merge, and table_set include implicit pstrdup()
6634 of the key and value. But in many cases this is not required
6635 because the key/value is a constant, or the value has been built
6636 by pstrcat() or other similar means. New routines table_addn,
6637 table_mergen, and table_setn have been added to the API, these
6638 routines do not pstrdup() their arguments. The core code and
6639 standard modules were changed to take advantage of these routines.
6640 The resulting server is up to 20% faster in some situations.
6642 Note that it is easy to get code subtly wrong if you pass a key/value
6643 which is in a pool other than the pool of the table. The only
6644 safe thing to do is to pass key/values which are in the pool of
6645 the table, or in one of the ancestors of the pool of the table.
6646 i.e. if the table is part of a subrequest, a value from the main
6647 request's pool is OK since the subrequest pool is a sub_pool of the
6648 main request's pool (and therefore has a lifespan at most as long as
6649 the main pool). There is debugging code which can detect improper
6650 usage, enabled by defining POOL_DEBUG. See alloc.c for more details.
6651 [Dmitry Khrustalev <dima@bog.msu.su>, Dean Gaudet]
6653 *) More mod_mime_magic cleanup: fewer syscalls; should handle "files"
6654 which don't exist on disk more gracefully; handles vhosts properly.
6655 Update documentation to reflect the code -- if there's no
6656 MimeMagicFile directive then the module is not enabled.
6659 *) PORT: Some older *nix dialects cannot automatically start scripts
6660 which begin with a #! interpreter line (the shell starts the scripts
6661 appropriately on these platforms). Apache now supports starting of
6662 "hashbang-scripts" when the NEED_HASHBANG_EMUL define is set.
6663 [Martin Kraemer, with code from peter@zeus.dialix.oz.au (Peter Wemm)
6666 *) API: "typedef array_header table" removed from alloc.h, folks should
6667 have been writing to use table as if it were an opaque type, but even
6668 some standard modules got this wrong. By changing the definition
6669 to "typedef struct table table" module authors will receive compile
6670 time warnings that they're doing the wrong thing. This change
6671 facilitates future changes with more sophisticated table
6672 structures. Specifically, module authors should be using table_elts()
6673 to get access to an array_header * for the table. [Dean Gaudet]
6675 *) API: Renamed new_connection() to avoid namespace collision with LDAP
6676 library routines. [Ken Coar, Rasmus Lerdorf]
6678 *) WIN32: mod_speling is now available on the Win32 platform.
6681 *) For clarity the following compile time definition was changed:
6683 SAFE_UNSERIALIZED_ACCEPT -> SINGLE_LISTEN_UNSERIALIZED_ACCEPT
6685 Also, for example, HAVE_MMAP would mean to use mmap() scoreboards
6686 and not be a general notice that the OS has mmap(). Now the
6687 HAVE_MMAP/SHMGET #defines strictly are informational that the
6688 OS has that method of shared memory; the type to use for
6689 the scoreboard is a seperate #define (USE_MMAP_SCOREBOARD
6690 and USE_SHMGET_SCOREBOARD). This allows outside modules to
6691 determine if shared memory is available and allows Apache
6692 to determine the best method to use for the scoreboard.
6695 *) PORT: UnixWare 2.1.2 SMP appears to require USE_FCNTL_SERIALIZED_ACCEPT,
6696 as do various earlier versions. It should be safe on all versions.
6697 Unixware 1.x appears to have the same SIGHUP bug as solaris does with
6698 the slack code. A few other cleanups for Unixware.

6701 *) PORT: A/UX can handle single-listen accepts without mutex
6702 locking, so we add SINGLE_LISTEN_UNSERIALIZED_ACCEPT. [Jim Jagielski]
6704 *) When die() happens we need to eat any request body if one exists.
6705 Otherwise we can't continue with a keepalive session. This shows up
6706 as a POST problem with MSIE 4.0, typically against pages which are
6707 authenticated. [Roy Fielding] PR#1399
6709 *) If you define SECURITY_HOLE_PASS_AUTHORIZATION then the Authorization
6710 header will be passed to CGIs. This is generally a security hole, so

6718 *) suexec errors now include the errno/description. [Marc Slemko] PR#1543
6720 *) PORT: OSF/1 now uses USE_FLOCK_SERIALIZED_ACCEPT to solve PR#467.
6721 The choice of flock vs. fcntl was made based on timings which showed that
6722 even on non-NFS, non-exported filesystems fcntl() was an order of
6723 magnitude slower. It also uses SINGLE_LISTEN_UNSERIALIZED_ACCEPT so
6724 that single socket users will see no difference. [Dean Gaudet] PR#467
6726 *) "File does not exist" error message was erroneously including the
6727 errno. [Marc Slemko]
6729 *) Improve the warning message generated when a client drops the

6734 necessary because SIGPROF is lost across a fork(). [Dean Gaudet]
6736 *) htdigest and htpasswd needed slight tweaks to work on OS/2 and WIN32.

6746 *) Some const declarations in mod_imap.c that were added for debugging
6747 purposes caused some compilers heartburn without adding any
6748 significant value, so they've been removed. [Ken Coar]
6750 *) The src/main/*.h header files have had #ifndef wrappers added to
6751 insulate them against duplicate calls if they get included through
6752 multiple paths (e.g., in .c files as well as other .h files).
6755 *) The libap routines now have a header file for their prototypes,
6756 src/ap/ap.h, to ease their use in non-httpd applications. [Ken Coar]
6758 *) mod_autoindex with a plaintext header file would emit the <PRE>
6759 start-tag before the HTML preamble, rather than after the preamble
6760 but before the header file contents. [John Van Essen <jve@gamers.org>]
6763 *) SECURITY: Fix a possible buffer overflow in logresolve. This is
6764 only an issue on systems without a MAXDNAME define or where
6765 the resolver returns domain names longer than MAXDNAME. [Marc Slemko]
6767 *) SECURITY: Eliminate possible buffer overflow in cfg_getline, which
6768 is used to read various types of files such as htaccess and
6769 htpasswd files. [Marc Slemko]
6771 *) SECURITY: Ensure that the buffer returned by ht_time is always
6772 properly null terminated. [Marc Slemko]
6774 *) The "Connection" header could be sent back with multiple "close"
6775 tokens. Not an error, but a waste.

6781 *) "basic" auth needs a case-insensitive comparison.
6782 [Ronald.Tschalaer@psi.ch] PR#1666
6784 *) For maximum portability, the environment passed to CGIs should
6785 only contain variables whose names match the regex
6786 /[a-zA-Z][a-zA-Z0-9_]*/. This is now enforced by stamping
6787 underscores over any character outside the regex. This
6788 affects HTTP_* variables, in a way that should be backward
6789 compatible for all the standard headers; and affects variables
6790 set with SetEnv/BrowserMatch and similar directives.

6877 [Ben Reser <breser@regnow.com>] PR#1366
6879 *) The bputc() macro was not properly integrated with the chunking
6880 code; in many cases modules using bputc() could cause completely
6881 bogus chunked output. (Typically this will show up as problems
6882 with Internet Explorer 4.0 reading a page, but other browsers
6883 having no problem.) [Dean Gaudet]
6885 *) Create LARGE_WRITE_THRESHOLD define which determines how many
6886 bytes have to be supplied to bwrite() before it will consider
6887 doing a writev() to assemble multiple buffers in one system
6888 call. This is critical for modules such as mod_include,
6889 mod_autoindex, mod_php3 which all use bputc()/bputs() of smaller
6890 strings in some cases. The result would be extra effort
6891 setting up writev(), and in many cases extra effort building
6892 chunks. The default is 31, it can be overriden at compile

6921 It also wouldn't handle "AddIconByType (TXT,/icons/text.gif text/*"

6924 *) It appears the "257th byte" bug (see

6961 now have a title in which the path components are clickable and allow
6962 quick navigation to the clicked-on directory on the currently listed
6963 ftp server. This also fixes a bug where the ".." directory links would

6983 The problem was that certain undocumented environment variables
6984 needed for sockets to work under Win32 were not being passed.

6987 *) Add a "-V" command line flag to the httpd binary. This
6988 flag shows some of the defines that Apache was compiled with.
6989 It is useful for debugging purposes. [Martin Kraemer]

6999 on all platforms. [Marc Slemko] PR#1214
7001 *) WIN32: Some Win32 systems terminated all responses after 16 kB.
7002 This turns out to be a bug in Winsock - select() doesn't always
7003 return the correct status. [Ben Laurie]
7005 *) Directives owned by http_core can now use the new check_cmd_context()
7006 routine to ensure that they're not being used within a container
7007 (e.g., <Directory>) where they're invalid. [Martin Kraemer]
7009 *) PORT: Recent changes made it necessary to add explicit prototype
7010 for fgetc() and fgets() on SunOS 4.x. [Martin Kraemer, Ben Hyde]
7012 *) It was necessary to distinguish between resources which are
7013 allocated in the parent, for cleanup in the parent, and resources
7014 which are allocated in each child, for cleanup in each child.
7015 A new pool was created which is passed to the module child_init
7016 and child_exit functions; modules are free to register per-child
7017 cleanups there. This fixes a bug with reliable piped logs.
7020 *) mod_autoindex wasn't displaying the ReadmeName file at the bottom
7021 unless it was also doing FancyIndexes, but it displayed the
7022 HeaderName file at the top under all circumstances. It now shows
7023 the ReadmeName file for simple indices, too, as it should.
7026 *) http_core was mmap()ing even in cases where it wasn't going to
7027 read the file. [Ben Hyde <bhyde@gensym.com>]
7029 *) Complete rewrite ;-) of mod_rewrite's URL rewriting engine:
7030 Now the rewriting engine (the heart of mod_rewrite) is organized more
7031 straight-forward, first time well documented and reduced to the really
7032 essential parts. All redundant cases were stripped off and processing now
7033 is the same for both per-server and per-directory context with only a
7034 minimum difference (the prefix stripping in per-dir context). As a
7035 side-effect some subtle restrictions and two recently discovered problems
7036 are gone: Wrong escaping of QUERY_STRING on redirects in per-directory
7037 context and restrictions on the substitution URL on redirects.
7038 Additionally some minor source cleanups were done.

7193 Changes with Apache 1.3b2 (there is no 1.3b1)
7195 *) TestCompile was not passing $LIBS [Dean Gaudet]
7197 *) Makefile.tmpl was not using $CFLAGS in the link phase.
7200 *) Add debugging code to alloc.c. Defining ALLOC_DEBUG provides a
7201 rudimentary memory debugger which can be used on live servers with
7202 low impact -- it sets all allocated and freed memory bytes to 0xa5.
7203 Defining ALLOC_USE_MALLOC will cause the alloc code to use malloc()
7204 and free() for each object. This is far more expensive and should
7205 only be used for testing with tools such as Electric Fence and
7206 Purify. See main/alloc.c for more details. [Dean Gaudet]
7208 *) Configure uses a sh trap and didn't set its exitcode properly.
7209 [Dean Gaudet] PR#1159
7211 *) Yet another vhost revamp. Add the NameVirtualHost directive which
7212 explicitly lists the ip:port pairs that are to be used for name-vhosts.
7213 From a given ip:port, regardless what the Host: header is, you can
7214 only reach the vhosts defined on that ip:port. The precedence of
7215 vhosts was reversed to match other precedences in the config --
7216 the earlier vhosts override the later vhosts. All vhost matching was
7217 moved into http_vhost.[ch]. [Dean Gaudet]
7219 *) ap_inline can be used to force inlining. GNUC __attribute__() can
7220 be used for whatever reason is appropriate (i.e. format() warnings
7221 for printf style functions). Both are enabled only with
7222 gcc >= 2.7.x (so that we have fewer support issues with older
7223 versions). [Dean Gaudet]
7225 *) Fix support for Proxy Authentication (we were testing the response
7226 status too early). [Marc Slemko]
7228 *) CoreDumpDirectory directive directs where the core file is
7229 written when a SIGSEGV, SIGBUS, SIGABORT or SIGABRT are
7230 received. [Marc Slemko, Dean Gaudet]
7232 *) PORT: Support for Atari MINT.
7233 [Jan Paul Schmidt <Jan.P.Schmidt@mni.fh-giessen.de>]
7235 *) When booting, apache will now detach itself from stdin, stdout,
7236 and stderr. stderr will not be detached until after the config
7237 files have been read so you will be able to see initial error
7238 messages. After that all errors are logged in the error_log.
7239 This makes it more convenient to start apache via rsh, ssh,
7240 or crontabs. [Dean Gaudet] PR#523
7242 *) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
7243 Also removed the auto-generated link to www.apache.org that was the
7244 source of so many misdirected bug reports. [Roy Fielding, Marc Slemko]
7246 *) send_fb would not detect aborted connections in some situations.
7249 *) mod_include would use uninitialized data when parsing certain
7250 expressions involving && and ||. [Brian Slesinsky] PR#1139
7252 *) mod_imap should only handle GET methods. [Jay Bloodworth]
7254 *) suexec.c wouldn't build without -DLOG_EXEC. [Jason A. Dour]
7256 *) mod_autoindex improperly counted &escapes; as more than one
7257 character in the description. It also improperly truncated
7258 descriptions that were exactly the maximum length.
7261 *) RedirectMatch was not properly escaping the result (PR#1155). Also
7262 "RedirectMatch /advertiser/(.*) $1" is now permitted.
7265 *) mod_include now uses symbolic names to check for request success
7266 and return HTTP errors, and correctly handles all types of
7267 redirections (previously it only did temporary redirect correctly).
7268 [Ken Coar, Roy Fielding]
7270 *) mod_userdir was modifying r->finfo in cases where it wasn't setting
7271 r->filename. Since those two are meant to be in sync with each other
7272 this is a bug. ["Paul B. Henson" <henson@intranet.csupomona.edu>]

7281 reporting a select error over and over.

7284 *) Fixed error in proxy_util.c when looping through multiple host IP
7285 addresses. [Lars Eilebrecht] PR#974
7287 *) If BUFFERED_LOGS is defined then mod_log_config will do atomic
7288 buffered writes -- that is, it will buffer up to PIPE_BUF (i.e. 4k)
7289 bytes before writing, but it will never split a log entry across a
7290 buffer boundary. [Dean Gaudet]
7292 *) API: the short_score record has been split into two pieces, one which
7293 the parent writes on, and one which the child writes on. As part of
7294 this change the get_scoreboard_info() function was removed, and
7295 scoreboard_image was exported. This change fixes a race condition
7296 in file based scoreboard systems, and speeds up changes involving the
7297 scoreboard in earlier 1.3 development. [Dean Gaudet]
7299 *) API: New register_other_child() API (see http_main.h) which allows
7300 modules to register children with the parent for maintenance. It
7301 is disabled by defining NO_OTHER_CHILD. [Dean Gaudet]
7303 *) API: New piped_log API (see http_log.h) which implements piped logs,
7304 and will use register_other_child to implement reliable piped logs
7305 when it is available. The reliable piped logs part can be disabled
7306 by defining NO_RELIABLE_PIPED_LOGS. At the moment reliable piped
7307 logs is only available on Unix. [Dean Gaudet]
7309 *) API: set_last_modified() broken into set_last_modified(), set_etag(), and
7310 meets_conditions(). This allows conditional HTTP selection to be
7311 handled separately from the storing of the header fields, and provides
7312 the ability for CGIs to set their own ETags for conditional checking.
7313 [Ken Coar, Roy Fielding] PR#895
7315 *) Changes to mod_log_config to allow naming of format strings.
7316 Format nicknames are defined with "LogFormat fmt nickname", and can
7317 be used with "LogFormat nickname" and "CustomLog logtarget nickname".
7320 *) New module, "mod_speling", which can help find files even when
7321 the URL is slightly misspelled. [Martin Kraemer, Alexei Kosut]
7323 *) API: New function child_terminate() triggers the child process to
7324 exit, while allowing the child finish what it needs to for the
7325 current request first.
7326 [Doug MacEachern, Alexei Kosut]
7328 *) Windows now defaults to using full status reports with mod_status.
7329 [Alexei Kosut] PR #1094
7331 *) *Really* disable all mod_rewrite operations if the engine is off.
7332 Some things (like RewriteMaps) were checked/performed even if they
7333 weren't supposed to be. [Ken Coar] PR #991
7335 *) Implement a new timer scheme which eliminates the need to call alarm() all
7336 the time. Instead a counter in the scoreboard for each child is used to
7337 show when the child has made forward progress. The parent samples this
7338 counter every scoreboard maintenance cycle, and issues SIGALRM if no
7339 progress has been made in the timeout period. This reduces the static
7340 request best-case syscall count to 22 from 29. This scheme is only
7341 used by systems with memory-based scoreboards. [Dean Gaudet]
7343 *) The proxy now properly handles CONNECT requests which are sent
7344 to proxy servers when using ProxyRemote. [Marc Slemko] PR#1024
7346 *) A script called apachectl has been added to the support
7347 directory. This script allows you to do things such as
7348 "apachectl start" and "apachectl restart" from the command
7351 *) Modules and core routines are now put into libraries, which
7352 simplifies the link line tremendously (among other advantages).
7355 *) Some of the MD5 names defined in Apache have been renamed to have
7356 an `ap_' prefix to avoid conflicts with routines supplied by
7357 external libraries. [Ken Coar]
7359 *) Removal of mod_auth_msql.c from the distribution. There are many
7360 other options for databases today. Rather than offer one option,
7361 offer none at this time. mod_auth_msql and other SQL database
7362 authentication modules can be found at the Apache Module Registry.
7363 http://modules.apache.org/ It would be nice to offer a generic
7364 mod_auth_sql option in the near future.
7366 *) PORT: BeOS support added [Alexei Kosut]
7368 *) Configure no longer accepts the -make option, since it creates
7369 Makefile on the fly based on Makefile.tmpl and Configuration.
7371 *) Apache now gracefully shuts down when it receives a SIGTERM, instead
7372 of forcibly killing off all its processes and exiting without
7373 cleaning up. [Alexei Kosut]
7375 *) API: A new field in the request_rec, r->mtime, has been added to
7376 avoid gratuitous parsing of date strings. It is intended to hold
7377 the last-modified date of the resource (if applicable). An
7378 update_mtime() routine has also been added to advance it if
7379 appropriate. [Roy Fielding, Ken Coar]
7381 *) SECURITY: If a htaccess file can not be read due to bad permissions,
7382 deny access to the directory with a HTTP_FORBIDDEN. The previous
7383 behavior was to ignore the htaccess file if it could not be read.
7384 This change may make some setups with unreadable htaccess files
7385 stop working. [Marc Slemko] PR#817
7387 *) Add aplog_error() providing a mechanism to define levels of
7388 verbosity to the server error logging. This addition also provides
7389 the ability to log errors using syslogd. Error logging is configurable
7390 on a per-server basis using the LogLevel directive. Conversion
7391 of log_*() in progress. [Randy Terbush]
7393 *) Further enhance aplog_error() to not log filename, line number, and
7394 errno information when it isn't applicable. [Ken Coar, Dean Gaudet]
7396 *) WIN32: Canonicalise filenames under Win32. Short filenames are
7397 converted to long ones. Backslashes are converted to forward
7398 slashes. Case is converted to lower. Parts of URLs that do not
7399 correspond to files are left completely alone. [Ben Laurie]
7401 *) PORT: 2 new OSs added to the list of ports:
7402 Encore's UMAX V: Arieh Markel <amarkel@encore.com>
7403 Acorn RISCiX: Stephen Borrill <sborrill@xemplar.co.uk>
7405 *) Add the server version (SERVER_VERSION macro) to the "server
7406 configured and running" entry in the error_log. Also build an
7407 object file at link-time that contains the current time
7408 (SERVER_BUILT global const char[]), and include that in the
7411 *) Set r->headers_out when sending responses from the proxy.
7412 This fixes things such as the logging of headers sent from
7413 the proxy. [Marc Slemko] PR#659
7415 *) support/httpd_monitor is no longer distributed because the
7416 scoreboard should not be file based if at all possible. Use
7417 mod_status to see current server snapshot.
7419 *) (set_file_slot): New function, allowing auth directives to be
7420 independent of the server root, so the server documents can be
7421 moved to a different directory or machine more easily.
7422 [David J. MacKenzie]
7424 *) If no TransferLog is given explicitly, decline
7425 to log. This supports coexistence with other logging modules,
7426 such as the custom one that UUNET uses. [David J. MacKenzie]
7428 *) Check for titles in server-parsed HTML files.
7429 Ignore leading newlines and returns in titles. The old behavior
7430 of replacing a newline after <title> with a space causes the
7431 title to be misaligned in the listing. [David J. MacKenzie]
7433 *) Change mod_cern_meta to be configurable on a per-directory basis.
7434 [David J. MacKenzie]
7436 *) Add 'Include' directive to allow inclusion of configuration
7437 files within configuration files. [Randy Terbush]
7439 *) Proxy errors on connect() are logged to the error_log (nothing
7440 new); now they include the IP address and port that failed
7441 (*that's* new). [Ken Coar, Marc Slemko] PR#352
7443 *) Various architectures now define USE_MMAP_FILES which causes
7444 the server to use mmap() for static files. There are two
7445 compile-time tunables MMAP_THRESHOLD (minimum number of bytes
7446 required to use mmap(), default is 0), and MMAP_SEGMENT_SIZE (maximum
7447 number of bytes written in one cycle from a single mmap()d object,
7448 default 32768). [Dean Gaudet]
7450 *) API: Added post_read_request API phase which is run right after reading
7451 the request from a client, or right after an internal redirect. It is
7452 useful for modules setting environment variables that depend only on
7453 the headers/contents of the request. It does not run during subrequests
7454 because subrequests inherit pretty much everything from the main
7455 request. [Dean Gaudet]
7457 *) Added mod_unique_id which is used to generate a unique identifier for
7458 each hit, available in the environment variable UNIQUE_ID.
7461 *) init_modules is now called after the error logs have been opened. This
7462 allows modules to emit information messages into the error logs.
7465 *) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
7466 information for case where proxy module is not available. [Marc Slemko]
7468 *) PORT: Apache has need for mutexes to serialize its children around
7469 accept. In prior versions either fcntl file locking or flock file
7470 locking were used. The method is chosen by the definition of
7471 USE_xxx_SERIALIZED_ACCEPT in conf.h. xxx is FCNTL for fcntl(),
7472 and FLOCK for flock(). New options have been added:
7473 - SYSVSEM to use System V style semaphores
7474 - PTHREAD to use POSIX threads (appears to work on Solaris only)
7475 - USLOCK to use IRIX uslock
7476 Based on timing various techniques, the following changes were made
7478 - Linux 2.x uses flock instead of fcntl
7479 - Solaris 2.x uses pthreads
7480 - IRIX uses SysV semaphores -- however multiprocessor IRIX boxes
7481 work far faster if you -DUSE_USLOCK_SERIALIZED_ACCEPT
7482 [Dean Gaudet, Pierre-Yves Kerembellec <Pierre-Yves.Kerembellec@vtcom.fr>,
7483 Martijn Koster <m.koster@pobox.com>]
7485 *) PORT: The semantics of accept/select make it very desirable to use
7486 mutexes to serialize accept when multiple Listens are in use. But
7487 in the case where only a single socket is open it is sometimes
7488 redundant to serialize accept(). Not all unixes do a good job with
7489 potentially dozens of children blocked on accept() on the same
7490 socket. It's now possible to define SINGLE_LISTEN_UNSERIALIZED_ACCEPT and
7491 the server will avoid serialization when listening on only one socket,
7492 and use serialization when listening on multiple sockets.
7493 [Dean Gaudet] PR#467
7495 *) Configure changes: TestLib replaced by TestCompile, which has
7496 some additional capability (such as doing a sanity check of
7497 the compiler and flags selected); the version of Solaris is now
7498 available via the #define value of SOLARIS2; IRIX n32bit libs
7499 now supported and selectable by new Configuration Rule: IRIXN32;
7500 We no longer default to -O2 optimization. [Jim Jagielski]
7502 *) Updated Configure: Configuration now uses AddModule to specify
7503 module source or binary file location, relative to src directory.
7504 Modules can be dropped into modules/extra, or in their own
7505 directory, and modules can come with a Makefile or Configure can
7506 create one. Modules can add compiler or library information to
7507 generated Makefiles. [Paul Sutton]
7509 *) Source core re-organisation: distributed modules are now in
7510 modules/standard. All other source code is in main. OS-specific
7511 code is in os/{unix,emx,win32} directories. [Paul Sutton]
7513 *) mod_browser has been removed, since it's replaced by mod_setenvif.
7516 *) Fix another long-standing bug in sub_req_lookup_file where it would
7517 happily skip past access checks on subdirectories looked up with
7518 relative paths. (It's used by mod_dir, mod_negotiation,
7519 and mod_include.) [Dean Gaudet]
7521 *) directory_walk optimization to reduce an O(N*M) loop to O(N+M) where
7522 N is the number of <Directory> sections, and M is the number of
7523 components in the filename of an object.
7525 To achieve this optimization the following config changes were made:
7526 - Wildcards (* and ?, not the regex forms) in <Directory>s,
7527 <Files>s, and <Location>s now treat a slash as a special
7528 character. For example "/home/*/public_html" previously would
7529 match "/home/a/andrew/public_html", now it only matches things
7530 like "/home/bob/public_html". This mimics /bin/sh behaviour.
7531 - It's possible now to use [] wildcarding in <Directory>, <Files>
7533 - Regex <Directory>s are applied after all non-regex <Directory>s.
7537 *) Fix a bug introduced in 1.3a1 directory_walk regarding .htaccess files
7538 and corrupted paths. [Dean Gaudet]
7540 *) Enhanced and cleaned up the URL rewriting engine of mod_rewrite:
7541 First the grouped parts of RewriteRule pattern matches (parenthesis!) can
7542 be accessed now via backreferences $1..$9 in RewriteConds test-against
7543 strings in addition to RewriteRules subst string. Second the grouped
7544 parts of RewriteCond pattern matches (parenthesis!) can be accessed now
7545 via backreferences %1..%9 both in following RewriteCond test-against
7546 strings and RewriteRules subst string. This provides maximum flexibility
7547 through the use of backreferences.
7548 Additionally the rewriting engine was cleaned up by putting common
7549 code to the new expand_backrefs_inbuffer() function.
7550 [Ralf S. Engelschall]
7552 *) When merging the main server's <Directory> and <Location> sections into
7553 a vhost, put the main server's first and the vhost's second. Otherwise
7554 the vhost can't override the main server. [Dean Gaudet] PR#717
7556 *) The <Directory> code would merge and re-merge the same section after
7557 a match was found, possibly causing problems with some modules.
7560 *) ip-based vhosts are stored and queried using a hashing function, which
7561 has been shown to improve performance on servers with many ip-vhosts.
7562 Some other changes had to be made to accommodate this:
7563 - the * address for vhosts now behaves like _default_
7564 - the matching process now is:
7565 - match an ip-vhost directly via hash (possibly matches main
7567 - if that fails, just pretend it matched the main server
7568 - if so far only the main server has been matched, perform
7569 name-based lookups (ServerName, ServerAlias, ServerPath)
7570 *only on name-based vhosts*
7571 - if they fail, look for _default_ vhosts
7572 [Dean Gaudet, Dave Hankins <dhankins@sugarat.net>]
7574 *) dbmmanage overhaul:
7575 - merge dbmmanage and dbmmanage.new functionality, remove dbmmanage.new
7576 - tie() to AnyDBM_File which will use one of DB_File, NDBM_File or
7577 GDBM_File (-ldb, -lndbm, -lgdbm) (trying each in that order)
7578 - provide better seed for rand
7579 - prompt for password as per getpass(3) (turn off echo, read from
7581 - use "newstyle" crypt based on $Config{osname} ($^O)
7582 - will not add a user if already in database, use new `update' command
7584 - added `check' command to check a users' password
7585 - added `import' command to convert existing password text-files or
7586 dbm files exported with `view'
7587 - more descriptive usage, general cleanup, 'use strict' clean, etc.
7590 *) Added psocket() which is a pool form of socket(), various places within
7591 the proxy weren't properly blocking alarms while registering the cleanup
7592 for its sockets. bclose() now uses pclose() and pclosesocket(). There
7593 was a bug where the client socket was being close()d twice due a still
7594 registered cleanup. [Dean Gaudet]
7596 *) A few cleanups were made to reduce time(), getpid(), and signal() calls.
7599 *) PORT: AIX >= 4.2 requires -lm due to libc changes.
7600 [Jason Venner <jason@idiom.com>] PR#667
7602 *) Enable ``=""'' for RewriteCond directives to match against
7603 the empty string. This is the preferred way instead of ``^$''.
7604 [Ralf S. Engelschall]
7606 *) Fixed an infinite loop in mod_imap for references above the server root
7607 [Dean Gaudet] PR#748
7609 *) mod_proxy now has a ReceiveBufferSize directive, similar to
7610 SendBufferSize, so that the TCP window can be set appropriately
7611 for LFNs. [Phillip A. Prindeville]
7613 *) mod_browser has been replaced by the more general mod_setenvif
7614 (courtesy of Paul Sutton). BrowserMatch* directives are still
7615 available, but are now joined by SetEnvIf*, UnSetEnvIf*, and
7616 UnSetEnvIfZero directives. [Ken Coar]
7618 *) "HostnameLookups double" forces double-reverse DNS to succeed in
7619 order for remote_host to be set (for logging, or for the env var
7620 REMOTE_HOST). The old define MAXIMUM_DNS has been deprecated.
7623 *) mod_access overhaul:
7624 - Now understands network/netmask syntax (i.e. 10.1.0.0/255.255.0.0)
7625 and cidr syntax (i.e. 10.1.0.0/16). PR#762
7626 - Critical path was sped up by pre-computing a few things at config time.
7627 - The undocumented syntax "allow user-agents" was removed,
7628 the replacement is "allow from env=foobar" combined with mod_browser.
7629 - When used with hostnames it now forces a double-reverse lookup
7630 no matter what the directory settings are. This double-reverse
7631 doesn't affect any of the other routines that use the remote
7632 hostname. In particular it's still passed to CGIs and the log
7633 without the double-reverse check. Related PR#860.
7636 *) When a large bwrite() occurs (larger than the internal buffer size),
7637 while there is already something in the buffer, apache will combine
7638 the large write and the buffer into a single writev(). (This is
7639 in anticipation of using mmap() for reading files.)
7642 *) In obscure cases where a partial socket write occurred while chunking,
7643 Apache would omit the chunk header/footer on the next block. Cleaned
7644 up other bugs/inconsistencies in error conditions in buff.c. Fixed
7645 a bug where a long pause in DNS lookups could cause the last packet
7646 of a response to be unduly delayed. [Roy Fielding, Dean Gaudet]
7648 *) API: Added child_exit function to module structure. This is called
7649 once per "heavy-weight process" just before a server child exit()'s
7650 e.g. when max_requests_per_child is reached, etc.
7651 [Doug MacEachern, Dean Gaudet]
7653 *) mod_include cleanup showed that handle_else was being used to handle
7654 endif. It didn't cause problems, but it was cleaned up too.
7657 *) mod_cern_meta would attempt to find meta files for the directory itself
7658 in some cases, but not in others. It now avoids it in all cases.
7661 *) mod_mime_magic would core dump if there was a decompression error.
7662 [Martin Kraemer <Martin.Kraemer@mch.sni.de>] PR#904
7664 *) PORT: some variants of DGUX require -lsocket -lnsl
7665 [Alexander L Jones <alex@systems-options.co.uk>] PR#732
7667 *) mod_autoindex now allows sorting of FancyIndexed directory listings
7668 by the various fields (name, size, et cetera), either in ascending
7669 or descending order. Just click on the column header. [Ken Coar]
7671 *) PORT: Various tweaks to eliminate pointer-int casting warnings on 64-bit
7672 CPUs like the Alpha. Apache still stores ints in pointers, but that's
7673 the relatively safe direction. [Dean Gaudet] PR#344
7675 *) PORT: QNX mmap() support for faster/more reliable scoreboard handling.
7676 [Igor N Kovalenko <infoh@mail.wplus.net>] PR#683
7678 *) child_main avoids an unneeded call to select() when there is only one
7679 listening socket. [Dean Gaudet]
7681 *) In the event that the server is starved for idle servers it will
7682 spawn 1, then 2, then 4, ..., then 32 servers each second,
7683 doubling each second. It'll also give a warning in the errorlog
7684 since the most common reason for this is a poor StartServers
7685 setting. The define MAX_SPAWN_RATE can be used to raise/lower
7686 the maximum. [Dean Gaudet]
7688 *) Apache now provides an effectively unbuffered connection for
7689 CGI scripts. This means that data will be sent to the client
7690 as soon as the CGI pauses or stops output; previously, Apache would
7691 buffer the output up to a fixed buffer size before sending, which
7692 could result in the user viewing an empty page until the CGI finished
7693 or output a complete buffer. It is no longer necessary to use an
7694 "nph-" CGI to get unbuffered output. Given that most CGIs are written
7695 in a language that by default does buffering (e.g. perl) this
7696 shouldn't have a detrimental effect on performance.
7698 "nph-" CGIs, which formerly provided a direct socket to the client
7699 without any server post-processing, were not fully compatible with
7700 HTTP/1.1 or SSL support. As such they would have had to implement
7701 the transport details, such as encryption or chunking, in order
7702 to work properly in certain situations. Now, the only difference
7703 between nph and non-nph scripts is "non-parsed headers".
7704 [Dean Gaudet, Sameer Parekh, Roy Fielding]
7706 *) If a BUFF is switched from buffered to unbuffered reading the first
7707 bread() will return whatever remained in the buffer prior to the
7708 switch. [Dean Gaudet]
7710 Changes with Apache 1.3a1
7712 *) Added another Configure helper script: TestLib. It determines
7713 if a specified library exists. [Jim Jagielski]
7715 *) PORT: Allow for use of n32bit libraries under IRIX 6.x
7716 [derived from patch from Jeff Hayes <jhayes@aw.sgi.com>]
7719 *) PORT: Some architectures use size_t for various lengths in network
7720 functions such as accept(), and getsockname(). The definition
7721 NET_SIZE_T is used to control this. [Dean Gaudet]
7723 *) PORT: Linux: Attempt to detect glibc based systems and include crypt.h
7724 and -lcrypt. Test for various db libraries (dbm, ndbm, db) when
7725 mod_auth_dbm or mod_auth_db are included. [Dean Gaudet]
7727 *) PORT: QNX doesn't have initgroups() which support/suexec.c uses.
7728 [Igor N Kovalenko <infoh@mail.wplus.net>]
7730 *) "force-response-1.0" now only applies to requests which are HTTP/1.0 to
7731 begin with. "nokeepalive" now works for HTTP/1.1 clients. Added
7732 "downgrade-1.0" which causes Apache to pretend it received a 1.0.
7733 [Dean Gaudet] related PR#875
7735 *) API: Correct child_init() slot declaration from int to void, to
7736 match the init() declaration. Update mod_example to use the new
7739 *) added transport handle slot (t_handle) to the BUFF structure
7742 *) get_client_block() returns wrong length if policy is
7743 REQUEST_CHUNKED_DECHUNK.
7744 [Kenichi Hori <ken@d2.bs1.fc.nec.co.jp>] PR#815
7746 *) Support the image map format of FrontPage. For example:
7747 rect /url.hrm 10 20 30 40
7748 ["Chris O'Byrne" <obyrne@iol.ie>] PR#807
7750 *) PORT: -lresolv and -lsocks were in the wrong order for Solaris.
7751 ["Darren O'Shaughnessy" <darren@aaii.oz.au>] PR#846
7753 *) AddModuleInfo directive for mod_info which allows you to annotate
7754 the output of mod_info. ["Lou D. Langholtz" <ldl@usi.utah.edu>]
7756 *) Added NoProxy directive to avoid using ProxyRemote for selected
7757 addresses. Added ProxyDomain directive to cause unqualified
7758 names to be qualified by redirection.
7759 [Martin Kraemer <Martin.Kraemer@mch.sni.de>]
7761 *) Support Proxy Authentication, and don't pass the Proxy-Authorize
7762 header to the remote host in the proxy. [Sameer Parekh and
7765 *) Upgraded mod_rewrite from 3.0.6+ to latest officially available version
7766 3.0.9. This upgrade includes: fixed deadlooping on rewriting to same
7767 URLs, fixed rewritelog(), fixed forced response code handling on
7768 redirects from within .htaccess files, disabled pipe locking under
7769 braindead SunOS 4.1.x, allow env variables to be set even on rules with
7770 no substitution, bugfixed situations where HostnameLookups is off, made
7771 mod_rewrite more thread-safe for NT port and fixed problem when creating
7772 an empty query string via "xxx?".
7773 This update also removes the copyright of Ralf S. Engelschall,
7774 i.e. now mod_rewrite no longer has a shared copyright. Instead is is
7775 exclusively copyrighted by the Apache Group now. This happened because
7776 the author now has gifted mod_rewrite exclusively to the Apache Group and
7777 no longer maintains an external version.
7778 [Ralf S. Engelschall]
7780 *) API: Added child_init function to module structure. This is called
7781 once per "heavy-weight process" before any requests are handled.
7782 See http_config.h for more details. [Dean Gaudet]
7784 *) Anonymous_LogEmail was logging on each subrequest.
7785 [Dean Gaudet] PR#421, 868
7787 *) API: Added is_initial_req() which tests if the request being
7788 processed is the initial request, or a subrequest.
7791 *) Extended SSI (mod_include) now handles additional relops for
7792 string comparisons (<, >, <=, and >=). [Bruno Wolff III] PR#41
7794 *) Configure fixed to correctly propagate user-selected options and
7795 settings (such as CC and OPTIM) to Makefiles other than
7796 src/Makefile (notably support/Makefile). [Ken Coar] PR#666, #834
7798 *) IndexOptions SuppressHTMLPreamble now causes the actual HTML of
7799 directory indices to start with the contents of the HeaderName file
7800 if there is one. If there isn't one, the behaviour is unchanged.
7801 [Ken Coar, Roy Fielding, Andrey A. Chernov]
7803 *) WIN32: Modules can now be dynamically loaded DLLs using the
7804 LoadModule/LoadFile directives. Note that module DLLs must be
7805 compiled with the multithreaded DLL version of the runtime library.
7806 [Alexei Kosut and Ben Laurie]
7808 *) Automatic indexing removed from mod_dir and placed into mod_autoindex.
7809 This allows the admin to completely remove automatic indexing
7810 from the server, while still supporting the basic functions of
7811 trailing-slash redirects and DirectoryIndex files. Note that if
7812 you're carrying over an old Configuration file and you use directory
7813 indexing then you'll want to add:
7815 Module autoindex_module mod_autoindex.o
7817 before mod_dir in your Configuration. [Dean Gaudet]
7819 *) popendir/pclosedir created to properly protect directory scanning.
7820 [Dean Gaudet] PR#525
7822 *) AliasMatch, ScriptAliasMatch and RedirectMatch directives added,
7823 giving regex support to mod_alias. <DirectoryMatch>, <LocationMatch>
7824 and <FilesMatch> sections added to succeed <DirectoryMatch ~>, etc...
7827 *) The AccessFileName directive can now take more than one filename.
7828 ["Lou D. Langholtz" <ldl@usi.utah.edu>]
7830 *) The new mod_mime_magic can be used to "magically" determine the type
7831 of a file if the extension is unknown. Based on the unix file(1)
7832 command. [Ian Kluft <ikluft@cisco.com>]
7834 *) We now determine and display the time spent processing a
7835 request if desired. [Jim Jagielski]
7837 *) mod_status: PID field of "dead" child slots no longer displays
7838 main httpd process's PID. [Jim Jagielski]
7840 *) Makefile.nt added - to build all the bits from the command line:
7841 nmake -f Makefile.nt
7842 Doesn't yet work properly. [Ben Laurie]
7844 *) Default text of 404 error is now "Not Found" rather than the
7845 potentially misleading "File Not Found". [Ken Coar]
7847 *) CONFIG: "HostnameLookups" now defaults to off because it is far better
7848 for the net if we require people that actually need this data to
7849 enable it. [Linus Torvalds]
7851 *) directory_walk() is an expensive function, keep a little more state to
7852 avoid needless string counting. Add two new functions make_dirstr_parent
7853 and make_dirstr_prefix which replace all existing uses of make_dirstr.
7854 The new functions are a little less general than make_dirstr, but
7855 work more efficiently (less memory, less string counting).
7858 *) EXTRA_LFLAGS was changed to EXTRA_LDFLAGS (and LFLAGS was changed
7859 to LDFLAGS) to avoid complications with lex rules in make files.
7860 [Dean Gaudet] PR#372
7862 *) run_method optimized to avoid needless scanning over NULLs in the
7863 module list. [Dean Gaudet]
7865 *) Revamp of (unix) scoreboard management code such that it avoids
7866 unnecessary traversals of the scoreboard on each hit. This is
7867 particularly important for high volume sites with a large
7868 HARD_SERVER_LIMIT. Some of the previous operations were O(n^2),
7869 and are now O(n). See also SCOREBOARD_MAINTENANCE_INTERVAL in
7870 httpd.h. [Dean Gaudet]
7872 *) In configurations using multiple Listen statements it was possible for
7873 busy sockets to starve other sockets of service. [Dean Gaudet]
7875 *) Added hook so standalone_main can be replaced at compile time
7876 (define STANDALONE_MAIN)
7879 *) Lowest-level read/write functions in buff.c will be replaced with
7880 the SFIO library calls sfread/sfwrite if B_SFIO is defined at
7881 compile time. The default sfio discipline will behave as apache
7882 would without sfio compiled in.
7885 *) Enhance UserDir directive (mod_userdir) to accept a list of
7886 usernames for the 'disable' keyword, and add 'enable user...' to
7887 selectively *en*able userdirs if they're globally disabled.
7890 *) If NETSCAPE_DBM_COMPAT is defined in EXTRA_CFLAGS then Apache
7891 will work with Netscape dbm files. (dbmmanage will probably not
7892 work however.) [Alexander Spohr <aspohr@netmatic.com>] PR#444
7894 *) Add a ListenBacklog directive to control the backlog parameter
7895 passed to listen(). Also change the default to 511 from 512.
7898 *) API: A new handler response DONE which informs apache that the
7899 request has been handled and it can finish off quickly, similar to
7900 how it handles errors. [Rob Hartill]
7902 *) Turn off chunked encoding after sending terminating chunk/footer
7903 so that we can't do it twice by accident. [Roy Fielding]
7905 *) mod_expire also issues Cache-Control: max-age headers.
7908 *) API: Added kill_only_once option for free_proc_chain so that it won't
7909 aggressively try to kill off specific children. For fastcgi.
7910 [Stanley Gambarin <gambarin@OpenMarket.com>]
7912 *) mod_auth deals with extra ':' delimited fields. [Marc Slemko]
7914 *) Added IconHeight and IconWidth to mod_dir's IndexOptions directive.
7915 When used together, these cause mod_dir to emit HEIGHT and WIDTH
7916 attributes in the FancyIndexing IMG tags. [Ken Coar]
7918 *) PORT: Sequent and SONY NEWS-OS support added. [Jim Jagielski]
7920 *) PORT: Added Windows NT support
7921 [Ben Laurie and Ambarish Malpani <ambarish@valicert.com>]
7923 Changes with Apache 1.2.6
7925 *) mod_include when using XBitHack Full would send ETags in addition to
7926 sending Last-Modifieds. This is incorrect HTTP/1.1 behaviour.
7927 [Dean Gaudet] PR#1133
7929 *) SECURITY: When a client connects to a particular port/addr, and
7930 gives a Host: header ensure that the virtual host requested can
7931 actually be reached via that port/addr. [Ed Korthof <ed@organic.com>]
7933 *) Support virtual hosts with wildcard port and/or multiple ports
7934 properly. [Ed Korthof <ed@organic.com>]
7936 *) Fixed some case-sensitivity issues according to RFC2068.
7939 *) Set r->allowed properly in mod_asis.c, mod_dir.c, mod_info.c,
7940 and mod_include.c. [Dean Gaudet]
7942 *) Variable 'cwd' was being used pointlessly before being set.
7945 *) SIGURG doesn't exist on all platforms.
7946 [Mark Andrew Heinrich <heinrich@tinderbox.Stanford.EDU>]
7948 *) When an error occurs during a POST, or other operation with a
7949 request body, the body has to be read from the net before allowing
7950 a keepalive session to continue. [Roy Fielding] PR#1399
7952 *) When an error occurs in fcntl() locking suggest the user look up
7953 the docs for LockFile. [Dean Gaudet]
7955 *) table_set() and table_unset() did not deal correctly with
7956 multiple occurrences of the same key. [Stephen Scheck
7957 <sscheck@infonex.net>, Ben Laurie] PR#1604
7959 *) send_fd_length() did not calculate total_bytes_sent properly in error
7960 cases. [Ben Reser <breser@regnow.com>] PR#1366
7962 *) r->connection->user was allocated in the wrong pool causing corruption
7963 in some cases when used with mod_cern_meta. [Dean Gaudet] PR#1500
7965 *) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
7966 Also removed the auto-generated link to www.apache.org that was the
7967 source of so many misdirected bug reports. [Roy Fielding, Marc Slemko]
7969 *) Multiple "close" tokens may have been set in the "Connection"
7970 header, not an error, but a waste.
7971 [Ronald.Tschalaer@psi.ch] PR#1683
7973 *) "basic" and "digest" auth tokens should be tested case-insensitive.
7974 [Ronald.Tschalaer@psi.ch] PR#1599, PR#1666
7976 *) It appears the "257th byte" bug (see
7977 htdocs/manual/misc/known_client_problems.html#257th-byte) can happen
7978 at the 256th byte as well. Fixed. [Dean Gaudet]
7980 *) mod_rewrite would not handle %3f properly in some situations.
7983 *) Apache could generate improperly chunked HTTP/1.1 responses when
7984 the bputc() or rputc() functions were used by modules (such as
7985 mod_include). [Dean Gaudet]
7987 *) #ifdef wrap a few #defines in httpd.h to make life easier on
7988 some ports. [Ralf Engelschall]

7994 *) Avoid B_ERROR redeclaration on sysvr4 systems. [Martin Kraemer]
7996 Changes with Apache 1.2.5
7998 *) SECURITY: Fix a possible buffer overflow in logresolve. This is
7999 only an issue on systems without a MAXDNAME define or where
8000 the resolver returns domain names longer than MAXDNAME. [Marc Slemko]
8002 *) Fix an improper length in an ap_snprintf call in proxy_date_canon().
8005 *) Fix core dump in the ftp proxy when reading incorrectly formatted
8006 directory listings. [Marc Slemko]
8008 *) SECURITY: Fix possible minor buffer overflow in the proxy cache.
8011 *) SECURITY: Eliminate possible buffer overflow in cfg_getline, which
8012 is used to read various types of files such as htaccess and
8013 htpasswd files. [Marc Slemko]
8015 *) SECURITY: Ensure that the buffer returned by ht_time is always
8016 properly null terminated. [Marc Slemko]
8018 *) SECURITY: General mod_include cleanup, including fixing several
8019 possible buffer overflows and a possible infinite loop. This cleanup
8020 was done against 1.3 code and then backported to 1.2, the result
8021 is a large difference (due to indentation cleanup in 1.3 code).
8022 Users interested in seeing a smaller set of relevant differences
8023 should consider comparing against src/modules/standard/mod_include.c
8024 from the 1.3b3 release. Non-indentation changes to mod_include
8025 between 1.2 and 1.3 were minimal. [Dean Gaudet, Marc Slemko]
8027 *) SECURITY: Numerous changes to mod_imap in a general cleanup
8028 including fixing a possible buffer overflow. This cleanup also
8029 was done with 1.3 code as a basis, see the the previous note
8030 about mod_include. [Dean Gaudet]
8032 *) SECURITY: If a htaccess file can not be read due to bad
8033 permissions, deny access to the directory with a HTTP_FORBIDDEN.
8034 The previous behavior was to ignore the htaccess file if it could not
8035 be read. This change may make some setups with unreadable
8036 htaccess files stop working. PR#817 [Marc Slemko]
8038 *) SECURITY: no2slash() was O(n^2) in the length of the input.
8039 Make it O(n). This inefficiency could be used to mount a denial
8040 of service attack against the Apache server. Thanks to

8048 [Jay Bloodworth <jay@pathways.sde.state.sc.us>]
8050 *) suexec.c wouldn't build without -DLOG_EXEC. [Jason A. Dour]
8052 *) mod_userdir was modifying r->finfo in cases where it wasn't setting
8053 r->filename. Since those two are meant to be in sync with each other
8054 this is a bug. ["Paul B. Henson" <henson@intranet.csupomona.edu>]

8066 Changes with Apache 1.2.4
8068 *) The ProxyRemote change in 1.2.3 introduced a bug resulting in the proxy
8069 always making requests with the full-URI instead of just the URI path.
8070 [Marc Slemko, Roy Fielding]
8072 *) Add -lm for AIX versions >= 4.2 to allow Apache to link properly
8073 on this platform. [Marc Slemko]
8075 Changes with Apache 1.2.3
8077 *) The request to a remote proxy was mangled if it was generated as the
8078 result of a ProxyPass directive. URL schemes other than http:// were not
8079 supported when ProxyRemote was used. PR#260, PR#656, PR#699, PR#713,
8080 PR#812 [Lars Eilebrecht]
8082 *) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
8083 information for case where proxy module is not available. [Marc Slemko]
8085 *) Force proxy to always respond as HTTP/1.0, which it was failing to
8086 do for errors and cached responses. [Roy Fielding]
8088 *) PORT: Improved support for ConvexOS 11. [Jeff Venters]
8090 Changes with Apache 1.2.2 [not released]
8092 *) Fixed another long-standing bug in sub_req_lookup_file where it would
8093 happily skip past access checks on subdirectories looked up with relative
8094 paths. (It's used by mod_dir, mod_negotiation, and mod_include.)
8097 *) Add lockfile name to error message printed out when
8098 USE_FLOCK_SERIALIZED_ACCEPT is defined.
8101 *) Enhanced the chunking and error handling inside the buffer functions.
8102 [Dean Gaudet, Roy Fielding]
8104 *) When merging the main server's <Directory> and <Location> sections into
8105 a vhost, put the main server's first and the vhost's second. Otherwise
8106 the vhost can't override the main server. [Dean Gaudet] PR#717
8108 *) The <Directory> code would merge and re-merge the same section after
8109 a match was found, possibly causing problems with some modules.
8112 *) Fixed an infinite loop in mod_imap for references above the server root.
8113 [Dean Gaudet] PR#748
8115 *) mod_include cleanup showed that handle_else was being used to handle
8116 endif. It didn't cause problems, but it was cleaned up too.
8119 *) Last official synchronization of mod_rewrite with author version (because
8120 mod_rewrite is now directly developed by the author at the Apache Group):
8121 o added diff between mod_rewrite 3.0.6+ and 3.0.9
8122 minus WIN32/NT stuff, but plus copyright removement.
8124 - workaround for detecting infinite rewriting loops
8125 - fixed setting of env vars when "-" is used as subst string
8126 - fixed forced response code on redirects (PR#777)
8127 - fixed cases where r->args is ""
8128 - kludge to disable locking on pipes under braindead SunOS
8129 - fix for rewritelog in cases where remote hostname is unknown
8130 - fixed totally damaged request_rec walk-back loop
8131 o remove static from local data and add static to global ones.
8132 o replaced ugly proxy finding stuff by simple
8133 find_linked_module("mod_proxy") call.
8134 o added missing negation char on rewritelog()
8135 o fixed a few comment typos
8136 [Ralf S. Engelschall]
8138 *) Anonymous_LogEmail was logging on each subrequest.
8139 [Dean Gaudet] PR#421, PR#868
8141 *) "force-response-1.0" now only applies to requests which are HTTP/1.0 to
8142 begin with. "nokeepalive" now works for HTTP/1.1 clients. Added
8143 "downgrade-1.0" which causes Apache to pretend it received a 1.0.
8144 Additionally mod_browser now triggers during translate_name to workaround
8145 a deficiency in the header_parse phase.

8162 *) PORT: The slack fd changes in 1.2.1 introduced a problem with SIGHUP
8163 under Solaris 2.x (up through 2.5.1). It has been fixed.
8164 [Dean Gaudet] PR#832
8166 *) API: In HTTP/1.1, whether or not a request message contains a body
8167 is independent of the request method and based solely on the presence
8168 of a Content-Length or Transfer-Encoding. Therefore, our default
8169 handlers need to be prepared to read a body even if they don't know
8170 what to do with it; otherwise, the body would be mistaken for the
8171 next request on a persistent connection. discard_request_body()
8172 has been added to take care of that. [Roy Fielding] PR#378
8174 *) API: Symbol APACHE_RELEASE provides a numeric form of the Apache
8175 release version number, such that it always increases along the
8176 same lines as our source code branching. [Roy Fielding]
8178 *) Minor oversight on multiple variants fixed. [Paul Sutton] PR#94
8180 Changes with Apache 1.2.1
8182 *) SECURITY: Don't serve file system objects unless they are plain files,
8183 symlinks, or directories. This prevents local users from using pipes
8184 or named sockets to invoke programs for an extremely crude form of

8188 could contain "../" allowing a local user to "publish" any file on
8189 the system. No slashes are allowed now. [Dean Gaudet]
8191 *) SECURITY: It was possible to violate the symlink Options using mod_dir
8192 (headers, readmes, titles), mod_negotiation (type maps), or
8193 mod_cern_meta (meta files). [Dean Gaudet]
8195 *) SECURITY: Apache will refuse to run as "User root" unless
8196 BIG_SECURITY_HOLE is defined at compile time. [Dean Gaudet]
8198 *) CONFIG: If a symlink pointed to a directory then it would be disallowed
8199 if it contained a .htaccess disallowing symlinks. This is contrary
8200 to the rule that symlink permissions are tested with the symlink
8201 options of the parent directory. [Dean Gaudet] PR#353
8203 *) CONFIG: The LockFile directive can be used to place the serializing
8204 lockfile in any location. It previously defaulted to /usr/tmp/htlock.
8205 [Somehow it took four of us: Randy Terbush, Jim Jagielski, Dean Gaudet,
8208 *) Request processing now retains state of whether or not the request
8209 body has been read, so that internal redirects and subrequests will
8210 not try to read it twice (and block). [Roy Fielding]
8212 *) Add a placeholder in modules/Makefile to avoid errors with certain
8213 makes. [Marc Slemko]
8215 *) QUERY_STRING was unescaped in mod_include, it shouldn't be.

8218 *) mod_include was not properly changing the current directory.
8219 [Marc Slemko] PR#742
8221 *) Attempt to work around problems with third party libraries that do not
8222 handle high numbered descriptors (examples include bind, and
8223 solaris libc). On all systems apache attempts to keep all permanent
8224 descriptors above 15 (called the low slack line). Solaris users
8225 can also benefit from adding -DHIGH_SLACK_LINE=256 to EXTRA_CFLAGS
8226 which keeps all non-FILE * descriptors above 255. On all systems
8227 this should make supporting large numbers of vhosts with many open
8228 log files more feasible. If this causes trouble please report it,
8229 you can disable this workaround by adding -DNO_SLACK to EXTRA_CFLAGS.
8230 [Dean Gaudet] various PRs
8232 *) Related to the last entry, network sockets are now opened before
8233 log files are opened. The only known case where this can cause
8234 problems is under Solaris with many virtualhosts and many Listen
8235 directives. But using -DHIGH_SLACK_LINE=256 described above will
8236 work around this problem. [Dean Gaudet]
8238 *) USE_FLOCK_SERIALIZED_ACCEPT is now default for FreeBSD, A/UX, and

8327 *) If a soft_timeout occurs after keepalive is set, then the main child
8328 loop would try to read another request even though the connection
8329 has been aborted. [Roy Fielding]
8331 *) Configure changes: Allow for whitespace at the start of a
8332 Module declaration. Also, be more understanding about the
8333 CC=/OPTIM= format in Configuration. Finally, fix compiler
8334 flags if using HP-UX's cc compiler. [Jim Jagielski]
8336 *) Subrequests and internal redirects now inherit the_request from the
8337 original request-line. [Roy Fielding]
8339 *) Test for error conditions before creating output header fields, since
8340 we don't want the error message to include those fields. Likewise,
8341 reset the content_language(s) and content_encoding of the response
8342 before generating or redirecting to an error message, since the new
8343 message will have its own Content-* definitions. [Dean Gaudet]

8346 and 304 responses) and err_headers_out (headers sent with all responses).
8347 Avoid the overhead of copying tables if err_headers_out is empty
8348 (the usual case). [Roy Fielding]

8351 not properly checking both the value configured by the DefaultType
8352 directive and the DEFAULT_TYPE symbol in httpd.h. Changed the value
8353 of DEFAULT_TYPE to match the documented default (text/plain).

8359 *) Properly initialize the flock structures used by the mutex locking
8360 around accept() when USE_FCNTL_SERIALIZED_ACCEPT is defined.
8363 *) The method for determining PATH_INFO has been restored to the pre-1.2b
8364 (and NCSA httpd) definition wherein it was the extra path info beyond
8365 the CGI script filename. The environment variable FILEPATH_INFO has
8366 been removed, and instead we supply the original REQUEST_URI to any
8367 script that wants to be Apache-specific and needs the real URI path.
8368 This solves a problem with existing scripts that use extra path info
8369 in the ScriptAlias directive to pass options to the CGI script.
8372 *) The _default_ change in 1.2b10 will change the behaviour on configs
8373 that use multiple Listen statements for listening on multiple ports.
8374 But that change is necessary to make _default_ consistent with other
8375 forms of <VirtualHost>. It requires such configs to be modified
8376 to use <VirtualHost _default_:*>. The documentation has been
8377 updated. [Dean Gaudet] PR#530
8379 *) If an ErrorDocument CGI script is used to respond to an error
8380 generated by another CGI script which has already read the message
8381 body of the request, the server would block trying to read the
8382 message body again. [Rob Hartill]

8461 parsing of headers. If the terminating empty-line CRLF occurs starting
8462 at the 256th or 257th byte of output, then Navigator will think a normal
8463 image is invalid. We are guessing that this is because their initial
8464 read of a new request uses a 256 byte buffer. We check the bytes written
8465 so far and, if we are about to tickle the bug, we instead insert a
8466 padding header of eminent bogosity. [Roy Fielding and Dean Gaudet] PR#232

8493 HAVE_SYS_RESOURCE_H (enable the RLimit commands).
8494 [Dean Gaudet] PR#336, PR#340
8496 *) Redirect did not preserve ?query_strings when present in the client's
8497 request. [Dean Gaudet]
8499 *) Configure was finding non-modules on EXTRA_LIBS. [Frank Cringle] PR#380
8501 *) Use /bin/sh5 on ULTRIX. [P. Alejandro Lopez-Valencia] PR#369
8503 *) Add UnixWare compile/install instructions. [Chuck Murcko]
8505 *) Add mod_example (illustration of API techniques). [Ken Coar]
8507 *) Add macro for memmove to conf.h for SUNOS4. [Marc Slemko]
8509 *) Improve handling of directories when filenames have spaces in them.
8512 *) For hosts with multiple IP addresses, try all additional addresses if
8513 necessary to get a connect. Fail only if hostent address list is
8514 exhausted. [Chuck Murcko]
8516 *) More signed/unsigned port fixes. [Dean Gaudet]
8518 *) HARD_SERVER_LIMIT can be defined in the Configuration file now.
8521 Changes with Apache 1.2b8
8523 *) suexec.c doesn't close the log file, allowing CGIs to continue writing
8524 to it. [Marc Slemko]
8526 *) The addition of <Location> and <File> directives made the
8527 sub_req_lookup_simple() function bogus, so we now handle
8528 the special cases directly. [Dean Gaudet]
8530 *) We now try to log where the server is dumping core when a fatal
8531 signal is received. [Ken Coar]
8533 *) Improved lingering_close by adding a special timeout, removing the
8534 spurious log messages, removing the nonblocking settings (they
8535 are not needed with the better timeout), and adding commentary
8536 about the NO_LINGCLOSE and USE_SO_LINGER issues. NO_LINGCLOSE is
8537 now the default for SunOS4, UnixWare, NeXT, and IRIX. [Roy Fielding]
8539 *) Send error messages about setsockopt failures to the server error
8540 log instead of stderr. [Roy Fielding]
8542 *) Fix loopholes in proxy cache expiry vis a vis alarms. [Brian Moore]
8544 *) Stopgap solution for CGI 3-second delay with server-side includes: if
8545 processing a subrequest, allocate memory from r->main->pool instead
8546 of r->pool so that we can avoid waiting for free_proc_chain to cleanup
8547 in the middle of an SSI request. [Dean Gaudet] PR #122
8549 *) Fixed status of response when POST is received for a nonexistent URL
8550 (was sending 405, now 404) and when any method is sent with a
8551 full-URI that doesn't match the server and the server is not acting
8552 as a proxy (was sending 501, now 403). [Roy Fielding]
8554 *) Host port changed to unsigned short. [Ken Coar] PR #276
8556 *) Fix typo in command definition of AuthAuthoritative. [Ken Coar] PR #246
8558 *) Defined USE_SHMGET_SCOREBOARD for shared memory on Linux. [Dean Gaudet]
8560 *) Report extra info from errno with many errors that cause httpd to exit.
8561 spawn_child, popenf, and pclosef now have valid errno returns in the
8562 event of an error. Correct problems where errno was stomped on
8563 before being reported. [Dean Gaudet]
8565 *) In the proxy, if the cache filesystem was full, garbage_coll() was
8566 never called, and thus the filesystem would remain full indefinitely.
8567 We now also remove incomplete cache files left if the origin server
8568 didn't send a Content-Length header and either the client has aborted
8569 transfer or bwrite() to client has failed. [Petr Lampa]
8571 *) Fixed the handling of module and script-added header fields.
8572 Improved the interface for sending header fields and reduced
8573 the duplication of code between sending okay responses and errors.
8574 We now always send both headers_out and err_headers_out, and
8575 ensure that the server-reserved fields are not being overridden,
8576 while not overriding those that are not reserved. [Roy Fielding]
8578 *) Moved transparent content negotiation fields to err_headers_out
8579 to reflect above changes. [Petr Lampa]
8581 *) Fixed the determination of whether or not we should make the
8582 connection persistent for all of the cases where some other part
8583 of the server has already indicated that we should not. Also
8584 improved the ordering of the test so that chunked encoding will
8585 be set whenever it is desired instead of only when KeepAlive
8586 is enabled. Added persistent connection capability for most error
8587 responses (those that do not indicate a bad input stream) when
8588 accessed by an HTTP/1.1 client. [Roy Fielding]
8590 *) Added missing timeouts for sending header fields, error responses,
8591 and the last chunk of chunked encoding, each of which could have
8592 resulted in a process being stuck in write forever. Using soft_timeout
8593 requires that the sender check for an aborted connection rather than
8594 continuing after an EINTR. Timeouts that used to be initiated before
8595 send_http_header (and never killed) are now initiated only within or
8596 around the routines that actually do the sending, and not allowed to
8597 propagate above the caller. [Roy Fielding]
8599 *) mod_auth_anon required an @ or a . in the email address, not both.
8602 *) per_dir_defaults weren't set correctly until directory_walk for
8603 name-based vhosts. This fixes an obscure bug with the wrong config
8604 info being used for vhosts that share the same ip as the server.
8607 *) Improved generation of modules/Makefile to be more generic for
8608 new module directories. [Ken Coar, Chuck Murcko, Roy Fielding]
8610 *) Generate makefile dependency for Configuration based on the actual
8611 name given when running the Configure process. [Dean Gaudet]
8613 *) Fixed problem with vhost error log not being set prior to
8614 initializing virtual hosts. [Dean Gaudet]
8616 *) Fixed infinite loop when a trailing slash is included after a type map
8617 file URL (extra path info). [Petr Lampa]
8619 *) Fixed server status updating of per-connection counters. [Roy Fielding]
8621 *) Add documentation for DNS issues (reliability and security), and try
8622 to explain the virtual host matching process. [Dean Gaudet]
8624 *) Try to continue gracefully by disabling the vhost if a DNS lookup
8625 fails while parsing the configuration file. [Dean Gaudet]
8627 *) Improved calls to setsockopt. [Roy Fielding]
8629 *) Negotiation changes: Don't output empty content-type in variant list;
8630 Output charset in variant list; Return sooner from handle_multi() if
8631 no variants found; Add handling of '*' wildcard in Accept-Charset.
8632 [Petr Lampa and Paul Sutton]
8634 *) Fixed overlaying of request/sub-request notes and headers in
8635 mod_negotiation. [Dean Gaudet]
8637 *) If two variants' charset quality are equal and one is the default
8638 charset (iso-8859-1), then prefer the variant that was specifically
8639 listed in Accept-Charset instead of the default. [Petr Lampa]
8641 *) Memory allocation problem in push_array() -- it would corrupt memory
8642 when nalloc==0. [Kai Risku <krisku@tf.hut.fi> and Roy Fielding]
8644 *) invoke_handler() doesn't handle mime arguments in content-type
8647 *) Reduced IdentityCheck timeout to 30 seconds, as per RFC 1413 minimum.
8650 *) Fixed problem with ErrorDocument not working for virtual hosts
8651 due to one of the performance changes in 1.2b7. [Dean Gaudet]
8653 *) Log an error message if we get a request header that is too long,
8654 since it may indicate a buffer overflow attack. [Marc Slemko]
8656 *) Made is_url() allow "[-.+a-zA-Z0-9]+:" as a valid scheme and
8657 not reject URLs without a double-slash, as per RFC2068 section 3.2.
8658 [Ken Coar] PR #146, #187
8660 *) Added table entry placeholder for new header_parser callback
8661 in all of the distributed modules. [Ken Coar] PR #191
8663 *) Allow for cgi files without the .EXE extension on them under OS/2.
8664 [Garey Smiley] PR #59
8666 *) Fixed error message when resource is not found and URL contains
8667 path info. [Petr Lampa and Dean Gaudet] PR #40
8669 *) Fixed user and server confusion over what should be a virtual host
8670 and what is the main server, resulting in access to something
8671 other than the name defined in the virtualhost directive (but
8672 with the same IP address) failing. [Dean Gaudet]
8674 *) Updated mod_rewrite to version 3.0.2, which: fixes compile error on
8675 AIX; improves the redirection stuff to enable the users to generally
8676 redirect to http, https, gopher and ftp; added TIME variable for
8677 RewriteCond which expands to YYYYMMDDHHMMSS strings and added the
8678 special patterns >STRING, <STRING and =STRING to RewriteCond, which
8679 can be used in conjunction with %{TIME} or other variables to create
8680 time-dependent rewriting rules. [Ralf S. Engelschall]
8682 *) bpushfd() no longer notes cleanups for the file descriptors it is handed.
8683 Module authors may need to adjust their code for proper cleanup to take
8684 place (that is, call note_cleanups_for_fd()). This change fixes problems
8685 with file descriptors being erroneously closed when the proxy module was
8686 in use. [Ben Laurie]
8688 *) Fix bug in suexec reintroduced by changes in 1.2b7 which allows
8689 initgroups() to hose the group information needed for later
8690 comparisons. [Randy Terbush]
8692 *) Remove unnecessary call to va_end() in create_argv() which
8693 caused a SEGV on some systems.
8695 *) Use proper MAXHOSTNAMELEN symbol for limiting length of server name.
8698 *) Clear memory allocated for listeners. [Randy Terbush]
8700 *) Improved handling of IP address as a virtualhost address and
8701 introduced "_default_" as a synonym for the default vhost config.
8702 [Dean Gaudet] PR #212
8704 Changes with Apache 1.2b7
8706 *) Port to UXP/DS(V20) [Toshiaki Nomura <nom@yk.fujitsu.co.jp>]
8708 *) unset Content-Length if chunked (RFC-2068) [Petr Lampa]
8710 *) mod_negotiation fixes [Petr Lampa] PR#157, PR#158, PR#159
8711 - replace protocol response numbers with symbols
8712 - save variant-list into main request notes
8713 - free allocated memory from subrequests
8714 - merge notes, headers_out and err_headers_out
8716 *) changed status check mask in proxy_http.c from "HTTP/#.# ### *" to
8717 "HTTP/#.# ###*" to be more lenient about what we accept.
8720 *) more proxy FTP bug fixes:
8721 - Changed send_dir() to remove user/passwd from displayed URL.
8722 - Changed login error messages to be more descriptive.
8723 - remove setting of SO_DEBUG socket option
8724 - Make ftp_getrc() more lenient about multiline responses,
8725 specifically, 230 responses which don't have continuation 230-
8726 on each line). These seem to be all NT FTP servers, and while
8727 perhaps questionable, they appear to be legal by RFC 959.
8728 - Add missing kill_timeout() after transfer to user completes.
8731 *) Fixed problem where a busy server could hang when restarting
8732 after being sent a SIGHUP due to child processes not exiting.
8735 *) Modify mod_include escaping so a '\' only signifies an escaped
8736 character if the next character is one that needs
8737 escaping. [Ben Laurie]
8739 *) Eliminated possible infinite loop in mod_imap when relative URLs are
8740 used with a 'base' directive that does not have a '/' in it.
8741 [Marc Slemko, reported by Onno Witvliet <onno@tc.hsa.nl>]
8743 *) Reduced the default timeout from 1200 seconds to 300, and the
8744 one in the sample configfile from 400 to 300. [Marc Slemko]
8746 *) Stop vbprintf from crashing if given a NULL string pointer;
8747 print (null) instead. [Ken Coar]
8749 *) Don't disable Nagle algorithm if system doesn't have TCP_NODELAY.
8750 [Marc Slemko and Roy Fielding]
8752 *) Fixed problem with mod_cgi-generated internal redirects trying to
8753 read the request message-body twice. [Archie Cobbs and Roy Fielding]
8755 *) Reduced timeout on lingering close, removed possibility of a blocked
8756 read causing the child to hang, and stopped logging of errors if
8757 the socket is not connected (reset by client). [Roy Fielding]
8759 *) Rearranged main child loop to remove duplication of code in
8760 select/accept and keep-alive requests, fixed several bugs regarding
8761 checking scoreboard_image for exit indication and failure to
8762 account for all success conditions and trap all error conditions,
8763 prevented multiple flushes before closing the socket; close the entire
8764 socket buffer instead of just one descriptor, prevent logging of
8765 EPROTO and ECONNABORTED on platforms where supported, and generally
8766 improved readability. [Roy Fielding]
8768 *) Extensive performance improvements. Cleaned up inefficient use of
8769 auto initializers, multiple is_matchexp calls on a static string,
8770 and excessive merging of response_code_strings. [Dean Gaudet]
8772 *) Added double-buffering to mod_include to improve performance on
8773 server-side includes. [Marc Slemko]
8775 *) Several fixes for suexec wrapper. [Randy Terbush]
8776 - Make wrapper work for files on NFS filesystem.
8777 - Fix portability problem of MAXPATHLEN.
8778 - Fix array overrun problem in clean_env().
8779 - Fix allocation of PATH environment variable
8781 *) Removed extraneous blank line is description of mod_status chars.
8784 *) Logging of errors from the call_exec routine simply went nowhere,
8785 since the logfile fd has been closed, so now we send them to stderr.
8786 [Harald T. Alvestrand]
8788 *) Fixed core dump when DocumentRoot is a CGI.
8789 [Ben Laurie, reported by geddis@tesserae.com]
8791 *) Fixed potential file descriptor leak in mod_asis; updated it and
8792 http_core to use pfopen/pfclose instead of fopen/fclose.
8793 [Randy Terbush and Roy Fielding]
8795 *) Fixed handling of unsigned ints in ap_snprintf() on some chips such
8796 as the DEC Alpha which is 64-bit but uses 32-bit ints.
8797 [Dean Gaudet and Ken Coar]
8799 *) Return a 302 response code to the client when sending a redirect
8800 due to a missing trailing '/' on a directory instead of a 301; now
8801 it is cacheable. [Markus Gyger]
8803 *) Fix condition where, if a bad directive occurs in .htaccess, and
8804 sub_request() goes first to this directory, then log_reason() will
8805 SIGSEGV because it doesn't have initialized r->per_dir_config.
8806 [PR#162 from Petr Lampa, fix by Marc Slemko and Dean Gaudet]
8808 *) Fix handling of lang_index in is_variant_better(). This was
8809 causing problems which resulted in the server sending the
8810 wrong language document in some cases. [Petr Lampa]
8812 *) Remove free() from clean_env() in suexec wrapper. This was nuking
8813 the clean environment on some systems.
8815 *) Tweak byteserving code (e.g. serving PDF files) to work around
8816 bugs in Netscape Navigator and Microsoft Internet Explorer.
8817 Emit Content-Length header when sending multipart/byteranges.
8820 *) Port to HI-UX/WE2. [Nick Maclaren]
8822 *) Port to HP MPE operating system for HP 3000 machines
8823 [Mark Bixby <markb@cccd.edu>]
8825 *) Fixed bug which caused a segmentation fault if only one argument
8826 given to RLimit* directives. [Ed Korthof]
8828 *) Continue persistent connection after 204 or 304 response. [Dean Gaudet]
8830 *) Improved buffered output to the client by delaying the flush decision
8831 until the BUFF code is actually about to read the next request.
8832 This fixes a problem introduced in 1.2b5 with clients that send
8833 an extra CRLF after a POST request. Also improved chunked output
8834 performance by combining writes using writev() and removing as
8835 many bflush() calls as possible. NOTE: Platforms without writev()
8836 must add -DNO_WRITEV to the compiler CFLAGS, either in Configuration
8837 or Configure, unless we have already done so. [Dean Gaudet]
8839 *) Fixed mod_rewrite bug which truncated the rewritten URL [Marc Slemko]
8841 *) Fixed mod_info output corruption bug introduced by buffer overflow
8842 fixes. [Dean Gaudet]
8844 *) Fixed http_protocol to correctly output all HTTP/1.1 headers, including
8845 for the special case of a 304 response. [Paul Sutton]
8847 *) Improved handling of TRACE method by bypassing normal method handling
8848 and header parsing routines; fixed Allow response to always allow TRACE.
8851 *) Fixed compiler warnings in the regex library. [Dean Gaudet]
8853 *) Cleaned-up some of the generated HTML. [Ken Coar]
8855 Changes with Apache 1.2b6
8857 *) Allow whitespace in imagemap mapfile coordinates. [Marc Slemko]
8859 *) Fix typo introduced in fix for potential infinite loop around
8860 accept() in child_main(). This change caused the rev to 1.2b6.
8861 1.2b5 was never a public beta.
8863 Changes with Apache 1.2b5
8865 *) Change KeepAlive semantics (On|Off instead of a number), add
8866 MaxKeepAliveRequests directive. [Alexei Kosut]
8868 *) Various NeXT compilation patches, as well as a change in
8869 regex/regcomp.c since that file also used a NEXT define.
8872 *) Allow * to terminate the end of a directory match in mod_dir.
8873 Allows /~* to match for both /~joe and /~joe/. [David Bronder]
8875 *) Don't call can_exec() if suexec_enabled. Calling this requires
8876 scripts executed by the suexec wrapper to be world executable, which
8877 defeats one of the advantages of running the wrapper. [Randy Terbush]
8879 *) Portability Fix: IRIX complained with 'make clean' about *pure* (removed)
8882 *) Migration from sprintf() to snprintf() to avoid buffer
8883 overflows. [Marc Slemko]
8885 *) Provide portable snprintf() implementation (ap_snprintf)
8886 as well as *cvt family. [Jim Jagielski]
8888 *) Portability Fix: NeXT lacks unistd.h so we wrap it's inclusion
8891 *) Remove mod_fastcgi.c from the distribution. This module appears
8892 to be maintained more through the Open Market channels and should
8893 continue to be easily available at http://www.fastcgi.com/
8895 *) Fixed bug in modules/Makefile that wouldn't allow building in more
8896 than one subdirectory (or cleaning, either). [Jeremy Laidman]
8898 *) mod_info assumed that the config files were relative to ServerRoot.
8901 *) CGI scripts called as an error document resulting from failed
8902 CGI execution would hang waiting for POST'ed data. [Rob Hartill]
8904 *) Log reason when mod_dir returns access HTTP_FORBIDDEN
8907 *) Properly check errno to prevent display of a directory index
8908 when server receives a long enough URL to confuse stat().
8911 *) Several security enhancements to suexec wrapper. It is _highly_
8912 recommended that previously installed versions of the wrapper
8913 be replaced with this version. [Randy Terbush, Jason Dour]
8915 - ~user execution now properly restricted to ~user's home
8916 directory and below.
8917 - execution restricted to UID/GID > 100
8918 - restrict passed environment to known variables
8919 - call setgid() before initgroups() (portability fix)
8920 - remove use of setenv() (portability fix)
8922 *) Add HTTP/1.0 response forcing. [Ben Laurie]
8924 *) Add access control via environment variables. [Ben Laurie]
8926 *) Add rflush() function. [Alexei Kosut]
8928 *) remove duplicate pcalloc() call in new_connection().
8930 *) Fix incorrect comparison which could allow number of children =
8931 MaxClients + 1 if less than HARD_SERVER_LIMIT. Also fix potential
8932 problem if StartServers > HARD_SERVER_LIMIT. [Ed Korthof]
8934 *) Updated support for OSes (MachTen, ULTRIX, Paragon, ISC, OpenBSD
8935 AIX PS/2, CONVEXOS. [Jim Jagielski]
8937 *) Replace instances of inet_ntoa() with inet_addr() for ProxyBlock.
8938 It's more portable. [Martin Kraemer]
8940 *) Replace references to make in Makefile.tmpl with $(MAKE).
8943 *) Add ProxyBlock directive w/IP address caching. Add IP address
8944 caching to NoCache directive as well. ProxyBlock works with all
8945 handlers; NoCache now also works with FTP for anonymous logins.
8946 Still more code cleanup. [Chuck Murcko]
8948 *) Add "header parse" API hook [Ben Laurie]
8950 *) Fix byte ordering problems for REMOTE_PORT [Chuck Murcko]
8952 *) suEXEC wrapper was freeing memory that had not been malloc'ed.
8954 *) Correctly allow access and auth directives in <Files> sections in
8955 server config files. [Alexei Kosut]
8957 *) Fix bug with ServerPath that could cause certain files to be not
8958 found by the server. [Alexei Kosut]
8960 *) Fix handling of ErrorDocument so that it doesn't remove a trailing
8961 double-quote from text and so that it properly checks for unsupported
8962 status codes using the new index_of_response interface. [Roy Fielding]
8964 *) Multiple fixes to the lingering_close code in order to avoid being
8965 interrupted by a stray timeout, to avoid lingering on a connection
8966 that has already been aborted or never really existed, to ensure that
8967 we stop lingering as soon as any error condition is received, and to
8968 prevent being stuck indefinitely if the read blocks. Also improves
8969 reporting of error conditions. [Marc Slemko and Roy Fielding]
8971 *) Fixed initialization of parameter structure for sigaction.
8972 [mgyger@itr.ch, Adrian Filipi-Martin]
8974 *) Fixed reinitializing the parameters before each call to accept and
8975 select, and removed potential for infinite loop in accept.
8976 [Roy Fielding, after useful PR from adrian@virginia.edu]
8978 *) Fixed condition where, if a child fails to fork, the scoreboard would
8979 continue to say SERVER_STARTING forever. Eventually, the main process
8980 would refuse to start new children because count_idle_servers() will
8981 count those SERVER_STARTING entries and will always report that there
8982 are enough idle servers. [Phillip Vandry]
8984 *) Fixed bug in bcwrite regarding failure to account for partial writes.
8985 Avoided calling bflush() when the client is pipelining requests.
8986 Removed unnecessary flushes from http_protocol. [Dean Gaudet]
8988 *) Added description of "." mode in server-status [Jim Jagielski]
8990 Changes with Apache 1.2b4
8992 *) Fix possible race condition in accept_mutex_init() that
8993 could leave a small security hole open allowing files to be
8994 overwritten in cases where the server UID has write permissions.
8997 *) Fix awk compatibilty problem in Configure. [Jim Jagielski]
8999 *) Fix portablity problem in util_script where ARG_MAX may not be
9000 defined for some systems.
9002 *) Add changes to allow compilation on Machten 4.0.3 for PowerPC.
9005 *) OS/2 changes to support an MMAP style scoreboard file and UNIX
9006 style magic #! token for better script portability. [Garey Smiley]
9008 *) Fix bug in suexec wrapper introduced in b3 that would cause failed
9009 execution for ~userdir CGI. [Jason Dour]
9011 *) Fix initgroups() business in suexec wrapper. [Jason Dour]
9013 *) Fix month off by one in suexec wrapper logging.
9015 Changes with Apache 1.2b3:
9017 *) Fix error in mod_cgi which could cause resources not to be properly
9018 freed, or worse. [Dean Gaudet]
9020 *) Fix find_string() NULL pointer dereference. [Howard Fear]
9022 *) Add set_flag_slot() at the request of Dirk and others.
9025 *) Sync mod_rewrite with patch level 10. [Ralf Engelschall]
9027 *) Add changes to improve the error message given for invalid
9028 ServerName parameters. [Dirk vanGulik]
9030 *) Add "Authoritative" directive for Auth modules that don't
9031 currently have it. This gives admin control to assign authoritative
9032 control to an authentication scheme and allow "fall through" for
9033 those authentication modules that aren't "Authoritative" thereby
9034 allowing multiple authentication mechanisms to be chained.
9037 *) Remove requirement for ResourceConfig/AccessConfig if not using
9038 the three config file layout. [Randy Terbush]
9040 *) Add PASV mode to mod_proxy FTP handler. [Chuck Murcko]
9042 *) Changes to suexec wrapper to fix the following problems:
9043 1. symlinked homedirs will kill ~userdirs.
9044 2. initgroups() on Linux 2.0.x clobbers gr->grid.
9045 3. CGI command lines paramters problems
9046 4. pw-pwdir for "docroot check" still the httpd user's pw record.
9047 [Randy Terbush, Jason Dour]
9049 *) Change create_argv() to accept variable arguments. This fixes
9050 a problem where arguments were not getting passed to the CGI via
9051 argv[] when the suexec wrapper was active. [Randy Terbush, Jake Buchholz]
9053 *) Collapse multiple slashes in path URLs to properly apply
9054 handlers defined by <Location>. [Alexei Kosut]
9056 *) Define a sane set of DEFAULT_USER and DEFAULT_GROUP values for AIX.
9058 *) Improve the accuracy of request duration timings by setting
9059 r->request_time in read_request_line() instead of read_request().
9062 *) Reset timeout while reading via get_client_block() in mod_cgi.c
9063 Fixes problem with timed out transfers of large files. [Rasmus Lerdorf]
9065 *) Add the ability to pass different Makefile.tmpl files to Configure
9066 using the -make flag. [Rob Hartill]
9068 *) Fix coredump triggered when sending a SIGHUP to the server caused
9069 by an assertion failure, in turn caused by an uninitialised field in a
9073 *) Add FILEPATH_INFO variable to CGI environment, which is equal to
9074 PATH_INFO from previous versions of Apache (in certain situations,
9075 Apache 1.2's PATH_INFO will be different than 1.1's). [Alexei Kosut]
9076 [later removed in 1.2b11]
9078 *) Add rwrite() function to API to allow for sending strings of
9079 arbitrary length. [Doug MacEachern]
9081 *) Remove rlim_t typedef for NetBSD. Do older versions need this?
9083 *) Defined rlim_t and WANTHSREGEX=yes and fixed waitpid() substitute for
9084 NeXT. [Jim Jagielski]
9086 *) Removed recent modification to promote the status code on internal
9087 redirects, since the correct fix was to change the default log format
9088 in mod_log_config so that it outputs the original status. [Rob Hartill]
9090 Changes with Apache 1.2b2:
9092 *) Update set_signals() to use sigaction() for setting handlers.
9093 This appears to fix a re-entrant problem in the seg_fault()
9094 bus_error() handlers. [Randy Terbush]
9096 *) Changes to allow mod_status compile for OS/2 [Garey Smiley]
9098 *) changes for DEC AXP running OSF/1 v3.0. [Marc Evans]
9100 *) proxy_http.c bugfixes: [Chuck Murcko]
9101 1) fixes possible NULL pointer reference w/NoCache
9102 2) fixes NoCache behavior when using ProxyRemote (ProxyRemote
9103 host would cache nothing if it was in the local domain,
9104 and the local domain was in the NoCache list)
9105 3) Adds Host: header when not available
9106 4) Some code cleanup and clarification
9108 *) mod_include.c bugfixes:
9109 1) Fixed an ommission that caused include variables to not
9110 be parsed in config errmsg directives [Howard Fear]
9111 2) Remove HAVE_POSIX_REGEX cruft [Alexei Kosut]
9112 3) Patch to fix compiler warnings [perrot@lal.in2p3.fr]
9113 4) Allow backslash-escaping to all quoted text
9114 [Ben Yoshino <ben@wiliki.eng.hawaii.edu>]
9115 5) Pass variable to command line if not set in XSSI's env
9118 *) Fix infinite loop when processing Content-language lines in
9119 type-map files. [Alexei Kosut]
9121 *) Closed file-globbing hole in test-cgi script. [Brian Behlendorf]
9123 *) Fixed problem in set_[user|group] that prevented CGI execution
9124 for non-virtualhosts when suEXEC was enabled. [Randy Terbush]
9126 *) Added PORTING information file. [Jim Jagielski]
9128 *) Added definitions for S_IWGRP and S_IWOTH to conf.h [Ben Laurie]
9130 *) Changed default group to "nogroup" instead of "nobody" [Randy Terbush]
9132 *) Fixed define typo of FCNTL_SERIALIZED_ACCEPT where
9133 USE_FCNTL_SERIALIZED_ACCEPT was intended.
9135 *) Fixed additional uses of 0xffffffff where INADDR_NONE was intended,
9136 which caused problems of systems where socket s_addr is >32bits.
9138 *) Added comment to explain (r->chunked = 1) side-effect in
9139 http_protocol.c [Roy Fielding]
9141 *) Replaced use of index() in mod_expires.c with more appropriate
9142 and portable isdigit() test. [Ben Laurie]
9144 *) Updated Configure for ...
9145 OS/2 (DEF_WANTHSREGEX=yes, other code changes)
9146 *-dg-dgux* (bad pattern match)
9147 QNX (DEF_WANTHSREGEX=yes)
9148 *-sunos4* (DEF_WANTHSREGEX=yes, -DUSEBCOPY)
9151 and added some user diagnostic info. [Ben Laurie]
9153 *) In helpers/CutRule, replaced "cut" invocation with "awk" invocation
9154 for better portability. [Jim Jagielski]
9156 *) Updated helpers/GuessOS for ...
9157 SCO 5 (recognize minor releases)
9158 SCO UnixWare (braindamaged uname, whatever-whatever-unixware2)
9159 SCO UnixWare 2.1.1 (requires a separate set of #defines in conf.h)
9160 IRIX64 (-sgi-irix64)
9161 ULTRIX (-unknown-ultrix)
9162 SINIX (-whatever-sysv4)
9163 NCR Unix (-ncr-sysv4)
9164 and fixed something in helpers/PrintPath [Ben Laurie]
9166 Changes with Apache 1.2b1
9168 *) Not listed. See <http://www.apache.org/docs/new_features_1_2.html>
9170 Changes with Apache 1.1.1
9172 *) Fixed bug where Cookie module would make two entries in the
9173 logfile for each access [Mark Cox]
9175 *) Fixed bug where Redirect in .htaccess files would cause memory
9176 leak. [Nathan Neulinger]
9178 *) MultiViews now works correctly with AddHandler [Alexei Kosut]
9180 *) Problems with mod_auth_msql fixed [Dirk vanGulik]
9182 *) Fix misspelling of "Anonymous_Authorative" directive in mod_auth_anon.
9184 Changes with Apache 1.1.0
9186 *) Bring NeXT support up to date. [Takaaki Matsumoto]
9188 *) Bring QNX support up to date. [Ben Laurie]
9190 *) Make virtual hosts default to main server keepalive parameters.
9191 [Alexei Kosut, Ben Laurie]
9193 *) Allow ScanHTMLTitles to work with lowercase <title> tags. [Alexei Kosut]
9195 *) Fix missing address family for connect, also remove unreachable statement
9196 in mod_proxy. [Ben Laurie]
9198 *) mod_env now turned on by default in Configuration.tmpl.
9200 *) Bugs which were fixed:
9201 a) yet more mod_proxy bugs [Ben Laurie]
9202 b) CGI works again with inetd [Alexei Kosut]
9203 c) Leading colons were stripped from passwords [osm@interguide.com]
9204 d) Another fix to multi-method Limit problem [jk@tools.de]
9206 Changes with Apache 1.1b4
9208 *) r->bytes_sent variable restored. [Robert Thau]
9210 *) Previously broken multi-method <Limit> parsing fixed. [Robert Thau]
9212 *) More possibly unsecure programs removed from the support directory.
9214 *) More mod_auth_msql authentication improvements.
9216 *) VirtualHosts based on Host: headers no longer conflict with the
9219 *) OS/2 compatibility enhancements. [Gary Smiley]
9221 *) POST now allowed to directory index CGI scripts.
9223 *) Actions now work with files of the default type.
9225 *) Bugs which were fixed:
9226 a) more mod_proxy bugs
9227 b) early termination of inetd requests
9228 c) compile warnings on several systems
9229 d) problems when scripts stop reading output early
9231 Changes with Apache 1.1b3
9233 *) Much of cgi-bin and all of cgi-src has been removed, due to
9234 various security holes found and that we could no longer support
9237 *) The "Set-Cookie" header is now special-cased to not merge multiple
9238 instances, since certain popular browsers can not handle multiple
9239 Set-Cookie instructions in a single header. [Paul Sutton]
9241 *) rprintf() added to buffer code, occurrences of sprintf removed.
9244 *) CONNECT method for proxy module, which means tunneling SSL should work.
9245 (No crypto needed) Also a NoCache config directive.
9247 *) Several API additions: pstrndup(), table_unset() and get_token()
9248 functions now available to modules.
9250 *) mod_imap fixups, in particular Location: headers are now complete
9253 *) New "info" module which reports on installed module set through a
9254 special URL, a la mod_status.
9256 *) "ServerPath" directive added - allows for graceful transition
9257 for Host:-header-based virtual hosts.
9259 *) Anonymous authentication module improvements.
9261 *) MSQL authentication module improvements.
9263 *) Status module design improved - output now table-based. [Ben Laurie]
9265 *) htdigest utility included for use with digest authentication
9268 *) mod_negotiation: Accept values with wildcards to be treated with
9269 less priority than those without wildcards at the same quality
9270 value. [Alexei Kosut]
9272 *) Bugs which were fixed:
9273 a) numerous mod_proxy bugs
9274 b) CGI early-termination bug [Ben Laurie]
9275 c) Keepalives not working with virtual hosts
9276 d) RefererIgnore problems
9277 e) closing fd's twice in mod_include (causing core dumps on
9278 Linux and elsewhere).
9280 Changes with Apache 1.1b2
9283 a) core dumps in mod_digest
9284 b) truncated hostnames/ip address in the logs
9285 c) relative URL's in mod_imap map files
9287 Changes with Apache 1.1b1
9289 *) Not listed. See <http://www.apache.org/docs/new_features_1_1.html>
9291 Changes with Apache 1.0.3
9293 *) Internal redirects which occur in mod_dir.c now preserve the
9294 query portion of a request (the bit after the question mark).
9297 *) Escape active characters '<', '>' and '&' in html output in
9298 directory listings, error messages and redirection links.
9301 *) Apache will now work with LynxOS 2.3 and later [Steven Watt]
9303 *) Fix for POSIX compliance in waiting for processes in alloc.c.
9306 *) setsockopt no longer takes a const declared argument [Martijn Koster]
9308 *) Reset timeout timer after each successful fwrite() to the network.
9309 This patch adds a reset_timeout() procedure that is called by
9310 send_fd() to reset the timeout ever time data is written to the net.
9313 *) timeout() signal handler now checks for SIGPIPE and reports
9314 lost connections in a more user friendly way. [Rob Hartill]
9316 *) Location of the "scoreboard" file which used to live in /tmp is
9317 now configurable (for OSes that can't use mmap) via ScoreBoardFile
9318 which works similar to PidFile (in httpd.conf) [Rob Hartill]
9320 *) Include sys/resource.h in the correct place for SunOS4 [Sameer Parekh]
9322 *) the pstrcat call in mod_cookies.c didn't have an ending NULL,
9323 which caused a SEGV with cookies enabled
9325 *) Output warning when MinSpareServers is set to <= 0 and change it to 1
9328 *) Log the UNIX textual error returned by some system calls, in
9329 particular errors from accept() [David Robinson]
9331 *) Add strerror function to util.c for SunOS4 [Randy Terbush]
9333 Changes with Apache 1.0.2
9335 *) patch to get Apache compiled on UnixWare 2.x, recommended as
9336 a temporary measure, pending rewrite of rfc931.c. [Chuck Murcko]
9338 *) Fix get_basic_auth_pw() to set the auth_type of the request.
9341 *) past changes to http_config.c to only use the
9342 setrlimit function on systems defining RLIMIT_NOFILE
9343 broke the feature on SUNOS4. Now defines HAVE_RESOURCE
9344 for SUNOS and prototypes the needed functions.
9346 *) Remove uses of MAX_STRING_LEN/HUGE_STRING_LEN from several routines.
9349 *) Fix use of pointer to scratch memory. [Cliff Skolnick]
9351 *) Merge multiple headers from CGI scripts instead of taking last
9352 one. [David Robinson]
9354 *) Add support for SCO 5. [Ben Laurie]
9356 Changes with Apache 1.0.1
9358 *) Silence mod_log_referer and mod_log_agent if not configured
9361 *) Recursive includes can occur if the client supplies PATH_INFO data
9362 and the server provider uses relative links; as file.html
9363 relative to /doc.shtml/pathinfo is /doc.shtml/file.html. [David Robinson]
9365 *) The replacement for initgroups() did not call {set,end}grent(). This
9366 had two implications: if anything else used getgrent(), then
9367 initgroups() would fail, and it was consuming a file descriptor.
9370 *) On heavily loaded servers it was possible for the scoreboard to get
9371 out of sync with reality, as a result of a race condition.
9372 The observed symptoms are far more Apaches running than should
9373 be, and heavy system loads, generally followed by catastrophic
9374 system failure. [Ben Laurie]
9376 *) Fix typo in license. [David Robinson]
9378 Changes with Apache 1.0.0 23 Nov 1995
9380 *) Not listed. See <http://www.apache.org/docs/new_features_1_0.html>
9382 Changes with Apache 0.8.16 05 Nov 1995
9384 *) New man page for 'httpd' added to support directory [David Robinson]
9386 *) .htgroup files can have more than one line giving members for a
9387 given group (each must have the group name in front), for NCSA
9388 back-compatibility [Robert Thau]
9390 *) Mutual exclusion around accept() is on by default for SVR4 systems
9391 generally, since they generally can't handle multiple processes in
9392 accept() on the same socket. This should cure flaky behavior on
9393 a lot of those systems. [David Robinson]
9395 *) AddType, AddEncoding, and AddLanguage directives take multiple
9396 extensions on a single command line [David Robinson]
9398 *) UserDir can be disabled for a given virtual host by saying
9399 "UserDir disabled" in the <VirtualHost> section --- it was a bug
9400 that this didn't work. [David Robinson]
9402 *) Compiles on QNX [Ben Laurie]
9404 *) Corrected parsing of ctime time format [David Robinson]
9406 *) httpd does a perror() before exiting if it can't log its pid
9407 to the PidFile, to make diagnosing the error a bit easier.
9410 *) <!--#include file="..."--> can no longer include files in the
9411 parent directory, for NCSA back-compatibility. [David Robinson]
9413 *) '~' is *not* escaped in URIs generated for directory listings
9416 *) Eliminated compiler warning in the imagemap module [Randy Terbush]
9418 *) Fixed bug involving handling URIs with escaped %-characters
9419 in redirects [David Robinson]
9421 Changes with Apache 0.8.15 14 Oct 1995
9423 *) Switched to new, simpler license
9425 *) Eliminated core dumps with improperly formatted DBM group files [Mark Cox]
9427 *) Don't allow requests for ordinary files to have PATH_INFO [Ben Laurie]
9429 *) Reject paths containing %-escaped '%' or null characters [David Robinson]
9431 *) Correctly handles internal redirects to files with names containing '%'
9434 *) Repunctuated some error messages [Aram Mirzadeh, Andrew Wilson]
9436 *) Use geteuid() rather than getuid() to see if we have root privilege,
9437 so that server correctly resets privilege if run setuid root. [Andrew
9440 *) Handle ftp: and telnet: URLs correctly in imagemaps (built-in module)
9443 *) Fix relative URLs in imagemap files [Randy Terbush]
9445 *) Somewhat better fix for the old "Alias /foo/ /bar/" business
9448 *) Don't repeatedly open the ErrorLog if a bunch of <VirtualHost>
9449 entries all name the same one. [David Robinson]
9451 *) Fix directory listings with filenames containing unusual characters
9454 *) Better URI-escaping for generated URIs in directories with filenames
9455 containing unusual characters [Ben Laurie]
9457 *) Fixed potential FILE* leak in http_main.c [Ben Laurie]
9459 *) Unblock alarms on error return from spawn_child() [David Robinson]
9461 *) Sample Config files have extra note for SCO users [Ben Laurie]
9463 *) Configuration has note for HP-UX users [Rob Hartill]
9465 *) Eliminated some bogus Linux-only #defines in conf.h [Aram Mirzadeh]
9467 *) Nuked bogus #define in httpd.h [David Robinson]
9469 *) Better test for whether a system has setrlimit() [David Robinson]
9471 *) Calls update_child_status() after reopen_scoreboard() [David Robinson]
9473 *) Doesn't send itself SIGHUP on startup when run in the -X debug-only mode
9476 Changes with Apache 0.8.14 19 Sep 1995
9478 *) Compiles on SCO ODT 3.0 [Ben Laurie]
9480 *) AddDescription works (better) [Ben Laurie]
9482 *) Leaves an intelligible error diagnostic when it can't set group
9483 privileges on standalone startup [Andrew Wilson]
9485 *) Compiles on NeXT again --- the 0.8.13 RLIMIT patch was failing on
9486 that machine, which claims to be BSD but does not support RLIMIT.
9489 *) gcc -Wall no longer complains about an unused variable when util.c
9490 is compiled with -DMINIMAL_DNS [Andrew Wilson]
9492 *) Nuked another compiler warning for -Wall on Linux [Aram Mirzadeh]
9494 Changes with Apache 0.8.13 07 Sep 1995
9496 *) Make IndexIgnore *work* (ooops) [Jarkko Torppa]
9498 *) Have built-in imagemap code recognize & honor Point directive [James
9501 *) Generate cleaner directory listings in directories with a mix of
9502 long and short filenames [Rob Hartill]
9504 *) Properly initialize dynamically loaded modules [Royston Shufflebotham]
9506 *) Properly default ServerName for virtual servers [Robert Thau]
9508 *) Rationalize handling of BSD in conf.h and elsewhere [Randy Terbush,
9509 Paul Richards and a cast of thousands...]
9511 *) On self-identified BSD systems (we don't try to guess any more),
9512 allocate a few extra file descriptors per virtual host with setrlimit,
9513 if we can, to avoid running out. [Randy Terbush]
9515 *) Write 22-character lock file name into buffer with enough space
9516 on startup [Konstantin Olchanski]
9518 *) Use archaic setpgrp() interface on NeXT, which requires it [Brian
9521 *) Suppress -Wall warning by casting const away in util.c [Aram Mirzadeh]
9523 *) Suppress -Wall warning by initializing variable in negotiation code
9524 [Tobias Weingartner]
9526 Changes with Apache 0.8.12 31 Aug 1995
9528 *) Doesn't pause three seconds after including a CGI script which is
9529 too slow to die off (this is done by not even trying to kill off
9530 subprocesses, including the SIGTERM/pause/SIGKILL routine, until
9531 after the entire document has been processed). [Robert Thau]
9533 *) Doesn't do SSI if Options Includes is off. (Ooops). [David Robinson]
9535 *) Options IncludesNoExec allows inclusion of at least text/* [Roy Fielding]
9537 *) Allows .htaccess files to override <Directory> sections naming the
9538 same directory [David Robinson]
9540 *) Removed an efficiency hack in sub_req_lookup_uri which was
9541 causing certain extremely marginal cases (e.g., ScriptAlias of a
9542 *particular* index.html file) to fail. [David Robinson]
9544 *) Doesn't log an error when the requested URI requires
9545 authentication, but no auth header line was supplied by the
9546 client; this is a normal condition (the client doesn't no auth is
9547 needed here yet). [Robert Thau]
9549 *) Behaves more sanely when the name server loses its mind [Sean Welch]
9551 *) RFC931 code compiles cleanly on old BSDI releases [Randy Terbush]
9553 *) RFC931 code no longer passes out name of prior clients on current
9554 requests if the current request came from a server that doesn't
9555 do RFC931. [David Robinson]
9557 *) Configuration script accepts "Module" lines with trailing whitespace.
9560 *) Cleaned up compiler warning from mod_access.c [Robert Thau]
9562 *) Cleaned up comments in mod_cgi.c [Robert Thau]
9564 Changes with Apache 0.8.11 24 Aug 1995
9566 *) Wildcard <Directory> specifications work. [Robert Thau]
9568 *) Doesn't loop for buggy CGI on Solaris [Cliff Skolnick]
9570 *) Symlink checks (FollowSymLinks off, or SymLinkIfOwnerMatch) always check
9571 the file being requested itself, in addition to the directories leading
9572 up to it. [Robert Thau]
9574 *) Logs access failures due to symlink checks or invalid client address
9575 in the error log [Roy Fielding, Robert Thau]
9577 *) Symlink checks deal correctly with systems where lstat of
9578 "/path/to/some/link/" follows the link. [Thau, Fielding]
9580 *) Doesn't reset DirectoryIndex to 'index.html' when
9581 other directory options are set in a .htaccess file. [Robert Thau]
9583 *) Clarified init code and nuked bogus warning in mod_access.c
9586 *) Corrected several directives in sample srm.conf
9587 --- includes corrections to directory indexing icon-related directives
9588 (using unknown.gif rather than unknown.xbm as the DefaultIcon, doing
9589 icons for encodings right, and turning on AddEncoding by default).
9592 *) Corrected descriptions of args to AddIcon and AddAlt in command table
9595 *) INSTALL & README mention "contributed modules" directory [Brian
9598 *) Fixed English in the license language... "for for" --> "for".
9601 *) Fixed ScriptAlias/Alias interaction by moving ScriptAlias handling to
9602 mod_alias.c, merging it almost completely with handling of Alias, and
9603 adding a 'notes' field to the request_rec which allows the CGI module
9604 to discover whether the Alias module has put this request through
9605 ScriptAlias (which it needs to know for back-compatibility, as the old
9606 NCSA code did not check Options ExecCGI in ScriptAlias directories).
9609 Changes with Apache 0.8.10 18 Aug 1995
9611 *) AllowOverride applies to the named directory, and not just
9612 subdirectories. [David Robinson]
9614 *) Do locking for accept() exclusion (on systems that need it)
9615 using a special file created for the purpose in /usr/tmp, and
9616 not the error log; using the error log causes real problems
9617 if it's NFS-mounted; this is known to be the cause of a whole
9618 lot of "server hang" problems with Solaris. [David Robinson;
9619 thanks to Merten Schumann for help diagnosing the problem].
9621 Changes with Apache 0.8.9 12 Aug 1995
9623 *) Compiles with -DMAXIMUM_DNS ---- ooops! [Henrik Mortensen]
9625 *) Nested includes see environment variables of the including document,
9626 for NCSA bug-compatibility (some sites have standard footer includes
9627 which try to print out the last-modified date). [Eric Hagberg/Robert
9630 *) <!--exec cgi="/some/uri/here"--> always treats the item named by the
9631 URI as a CGI script, even if it would have been treated as something
9632 else if requested directly, for NCSA back-compatibility. (Note that
9633 this means that people who know the name of the script can see the
9634 code just by asking for it). [Robert Thau]
9636 *) New version of dbmmanage script included in support directory as
9639 *) Check if scoreboard file couldn't be opened, and say so, rather
9640 then going insane [David Robinson]
9642 *) POST to CGI works on A/UX [Jim Jagielski]
9644 *) AddIcon and AddAlt commands work properly [Rob Hartill]
9646 *) NCSA server push works properly --- the Arena bug compatibility
9647 workaround, which broke it, is gone (use -DARENA_BUG_WORKAROUND
9648 if you still want the workaround). [Rob Hartill]
9650 *) If client didn't submit any Accept-encodings, ignore encodings in
9651 content negotiation. (NB this will all have to be reworked anyway
9652 for the new HTTP draft). [Florent Guillaume]
9654 *) Don't dump core when trying to log timed-out requests [Jim Jagielski]
9656 *) Really honor CacheNegotiatedDocs [Florent Guillaume]
9658 *) Give Redirect priority over Alias, for NCSA bug compatibility
9661 *) Correctly set PATH_TRANSLATED in all cases from <!--#exec cmd=""-->,
9662 paralleling earlier bug fix for CGI [David Robinson]
9664 *) If DBM auth is improperly configured, report a server error and don't
9667 *) Deleted FCNTL_SERIALIZED_ACCEPTS from conf.h entry for A/UX;
9668 it seems to work well enough without it (even in a 10 hits/sec
9669 workout), and the overhead for the locking under A/UX is
9670 alarmingly high (though it is very low on other systems).
9671 [Eric Hagberg, Jim Jagielski]
9673 *) Fixed portability problems with mod_cookies.c [Cliff Skolnick]
9675 *) Further de-Berklize mod_cookies.c; change the bogus #include. [Brian
9676 Behlendorf/Eric Hagberg]
9678 *) More improvements to default Configuration for A/UX [Jim Jagielski]
9680 *) Compiles clean on NEXT [Rob Hartill]
9682 *) Compiles clean on SGI [Robert Thau]
9684 Changes with Apache 0.8.8 08 Aug 1995
9686 *) SunOS library prototypes now never included unless explicitly
9687 requested in the configuration (via -DSUNOS_LIB_PROTOTYPES);
9688 people using GNU libc on SunOS are screwed by prototypes for the
9691 (Those who wish to compile clean with gcc -Wall on a standard
9692 SunOS setup need the prototypes, and may obtain them using
9693 -DSUNOS_LIB_PROTOTYPES. Those wishing to use -Wall on a system
9694 with nonstandard libraries are presumably competent to make their
9697 *) Strips trailing '/' characters off both args to the Alias command,
9698 to make 'Alias /foo/ /bar/' work.
9700 Changes with Apache 0.8.7 03 Aug 1995
9702 *) Don't hang when restarting with a child from 'TransferLog "|..."' running
9703 [reported by David Robinson]
9705 *) Compiles clean on OSF/1 [David Robinson]
9707 *) Added some of the more recent significant changes (AddLanguage stuff,
9708 experimental LogFormat support) to CHANGES file in distribution root
9711 Changes with Apache 0.8.6 02 Aug 1995
9713 *) Deleted Netscape reload workaround --- it's in violation of HTTP specs.
9714 (If you actually wanted a conditional GET which bypassed the cache, you
9715 couldn't get it). [Reported by Roy Fielding]
9717 *) Properly terminate headers on '304 Not Modified' replies to conditional
9718 GETs --- no browser we can find cares much, but the CERN proxy chokes.
9719 [Reported by Cliff Skolnick; fix discovered independently by Rob Hartill]
9721 *) httpd -v doesn't call itself "Shambhala". [Reported by Chuck Murcko]
9723 *) SunOS lib-function prototypes in conf.h conditionalized on __GNUC__,
9724 not __SUNPRO_C (they're needed to quiet gcc -Wall, but acc chokes on 'em,
9725 and older versions don't set the __SUNPRO_C preprocessor variable). On
9726 all other systems, these are never used anyway. [Reported by Mark Cox].
9728 *) Scoreboard file (/tmp/htstatus.*) no longer publically writable.
9730 Changes with Apache 0.8.5 01 Aug 1995
9732 *) Added last-minute configurable log experiment, as optional module
9734 *) Correctly set r->bytes_sent for HTTP/0.9 requests, so they get logged
9735 properly. (One-line fix to http_protocol.c).
9737 *) Work around bogus behavior when reloading from Netscape.
9738 It's Netscape's bug --- for some reason they expect a request with
9739 If-modified-since: to not function as a conditional GET if it also
9740 comes with Pragma: no-cache, which is way out of line with the HTTP
9741 spec (according to Roy Fielding, the redactor).
9743 *) Added parameter to set maximum number of server processes.
9745 *) Added patches to make it work on A/UX. A/UX is *weird*. [Eric Hagberg,
9748 *) IdentityCheck bugfix [Chuck Murcko].
9750 *) Corrected cgi-src/Makefile entry for new imagemap script. [Alexei Kosut]
9752 *) More sample config file corrections; add extension to AddType for
9753 *.asis, move AddType generic description to its proper place, and
9754 fix miscellaneous typos. [ Alexei Kosut ]
9756 *) Deleted the *other* reference to the regents from the Berkeley
9757 legal disclaimer (everyplace).
9759 *) Nuked Shambhala name from src/README; had already cleaned it out
9762 Changes with Apache 0.8.4
9764 *) Changes to server-pool management parms --- renamed current
9765 StartServers to MinSpareServers, created separate StartServers
9766 parameter which means what it says, and renamed MaxServers to
9767 MaxSpareServers (though the old name still works, for NCSA 1.4
9768 back-compatibility). The old names were generally regarded as
9769 too confusing. Also altered "docs" in sample config files.
9771 *) More improvements to default config files ---
9772 sample directives (commented out) for XBitHack, BindAddress,
9773 CacheNegotiatedDocs, VirtualHost; decent set of AddLanguage
9774 defaults, AddTypes for send-as-is and imagemap magic types, and
9775 improvements to samples for DirectoryIndex [Alexei Kosut]
9777 *) Yet more improvements to default config files --- changes to
9778 Alexei's sample AddLanguage directives, and sample LanguagePriority
9779 [ Florent Guillaume ]
9781 *) Set config file locations properly if not set in httpd.conf
9784 *) Don't escape URIs in internal redirects multiple times; don't
9785 do that when translating PATH_INFO to PATH_TRANSLATED either.
9788 *) Corrected spelling of "Required" in 401 error reports [Andrew Wilson]
9790 Changes with Apache 0.8.3
9792 *) Edited distribution README to *briefly* summarize installation
9793 procedures, and give a pointer to the INSTALL file in the src/
9796 *) Upgraded imagemap script in cgi-bin to 1.8 version from more
9797 recent NCSA distributions.
9799 *) Bug fix to previous bug fix --- if .htaccess file and <Directory>
9800 exist for the same directory, use both and don't segfault. [Reported
9803 *) Proper makefile dependencies [David Robinson]
9805 *) Note (re)starts in error log --- reported by Rob Hartill.
9807 *) Only call no2slash() after get_path_info() has been done, to
9808 preserve multiple slashes in the PATH_INFO [NCSA compatibility,
9809 reported by Andrew Wilson, though this one is probably a real bug]
9811 *) Fixed mod_imap.c --- relative paths with base_uri referer don't
9812 dump core when Referer is not supplied. [Randy Terbush]
9814 *) Lightly edited sample config files to refer people to our documentation
9815 instead of NCSA's, and to list Rob McCool as *original* author (also
9816 deleted his old, and no doubt non-functional email address). Would be
9817 nice to have examples of new features...
9819 Changes with Apache 0.8.2 19 Jul 1995
9821 *) Added AddLanuage code [Florent Guillaume]
9823 *) Don't say "access forbidden" when a CGI script is not found. [Mark Cox]
9825 *) All sorts of problems when MultiViews finds a directory. It would
9826 be nice if mod_dir.c was robust enough to handle that, but for now,
9827 just punt. [reported by Brian Behlendorf]
9829 *) Wait for all children on restart, to make sure that the old socket
9830 is gone and we can reopen it. [reported by Randy Terbush]
9832 *) Imagemap module is enabled in default Configuration
9834 *) RefererLog and UserAgentLog modules properly default the logfile
9837 *) Mark Cox's mod_cookies added to the distribution as an optional
9838 module (commented out in the default Configuration, and noted as
9839 an experiment, along with mod_dld). [Mark Cox]
9841 *) Compiles on ULTRIX (a continuing battle...). [Robert Thau]
9843 *) Fixed nasty bug in SIGTERM handling [reported by Randy Terbush]
9845 *) Changed "Shambhala" to "Apache" in API docs. [Robert Thau]
9847 *) Added new, toothier legal disclaimer. [Robert Thau; copied from BSD
9850 Changes with Apache 0.8.1
9852 *) New imagemap module [Randy Terbush]
9854 *) Replacement referer log module with NCSA-compatible RefererIgnore
9855 [Matthew Gray again]
9857 *) Don't mung directory listings with very long filenames.
9860 Changes with Apache 0.8.0 (nee Shambhala 0.6.2) 16 Jul 1995
9862 *) New config script. See INSTALL for info. [Robert Thau]
9864 *) Scoreboard mechanism for regulating the number of extant server
9865 processes. MaxServers and StartServers defaults are the same as
9866 for NCSA, but the meanings are slightly different. (Actually,
9867 I should probably lower the MaxServers default to 10).
9869 Before asking for a new connection, each server process checks
9870 the number of other servers which are also waiting for a
9871 connection. If there are more than MaxServers, it quietly dies
9872 off. Conversely, every second, the root, or caretaker, process
9873 looks to see how many servers are waiting for a new connection;
9874 if there are fewer than StartServers, it starts a new one. This
9875 does not depend on the number of server processes already extant.
9876 The accounting is arranged through a "scoreboard" file, named
9877 /tmp/htstatus.*, on which each process has an independent file
9878 descriptor (they need to seek without interference).
9880 The end effect is that MaxServers is the maximum number of
9881 servers on an *inactive* server machine, but more will be forked
9882 off to handle unusually heavy loads (or unusually slow clients);
9883 these will die off when they are no longer needed --- without
9884 reverting to the overhead of full forking operation. There is a
9885 hard maximum of 150 server processes compiled in, largely to
9886 avoid forking out of control and dragging the machine down.
9887 (This is arguably too high).
9889 In my server endurance tests, this mechanism did not appear to
9890 impose any significant overhead, even after I forced it to put the
9891 scoreboard file on a normal filesystem (which might have more
9892 overhead than tmpfs). [Robert Thau]
9894 *) Set HTTP_FOO variables for SSI <!--#exec cmd-->s, not just CGI scripts.
9897 *) Read .htaccess files even in directory with <Directory> section.
9898 (Former incompatibility noted on mailing list, now fixed). [Robert
9901 *) "HEAD /" gives the client a "Bad Request" error message, rather
9902 than trying to send no body *and* no headers. [Cliff Skolnick].
9904 *) Don't produce double error reports for some very obscure cases
9905 mainly involving auth configuration (the "all modules decline to
9906 handle" case which is a sure sign of a server bug in most cases,
9907 but also happens when authentication is badly misconfigured).
9910 *) Moved FCNTL_SERIALIZED_ACCEPT defines into conf.h (that's what
9911 it's *for*, and this sort of thing really shouldn't be cluttering
9912 up the Makefile). [Robert Thau]
9914 *) Incidental code cleanups in http_main.c --- stop dragging
9915 sa_client around; just declare it where used. [Robert Thau]
9917 *) Another acc-related fix. (It doesn't like const char
9918 in some places...). [Mark Cox]
9920 Changes with Shambhala 0.6.1 13 Jul 1995
9922 *) Fixed auth_name-related typos in http_core.c [Brian Behlendorf]
9923 Also, fixed auth typo in http_protocol.c unmasked by this fix.
9925 *) Compiles clean with acc on SunOS [Paul Sutton]
9927 *) Reordered modules in modules.c so that Redirect takes priority
9928 over ScriptAlias, for NCSA bug-compatibility [Rob Hartill] ---
9929 believe it or not, he has an actual site with a ScriptAlias and
9930 a Redirect declared for the *exact same directory*. Even *my*
9931 compatibility fetish wouldn't motivate me to fix this if the fix
9932 required any effort, but it doesn't, so what the hey.
9934 *) Fixed to properly default several server_rec fields for virtual
9935 servers from the corresponding fields in the main server_rec.
9936 [Cliff Skolnick --- 'port' was a particular irritant].
9938 *) No longer kills off nph- child processes before they are
9939 finished sending output. [Matthew Gray]
9941 Changes with Shambhala 0.6.0 10 Jul 1995
9943 *) Two styles of timeout --- hard and soft. soft_timeout()s just put
9944 the connection to the client in an "aborted" state, but otherwise
9945 allow whatever handlers are running to clean up. hard_timeout()s
9946 abort the request in progress completely; anything not tied to some
9947 resource pool cleanup will leak. They're still around because I
9948 haven't yet come up with a more elegant way of handling
9949 timeouts when talking to something that isn't the client. The
9950 default_handler and the dir_handler now use soft timeouts, largely
9951 so I can test the feature. [Robert Thau]
9953 *) TransferLog "| my_postprocessor ..." seems to be there. Note that
9954 the case of log handlers dying prematurely is probably handled VERY
9955 gracelessly at this point, and if the logger stops reading input,
9956 the server will hang. (It is known to correctly restart the
9957 logging process on server restart; this is (should be!) going through
9958 the same SIGTERM/pause/SIGKILL routine used to ding an errant CGI
9959 script). [Robert Thau]
9961 *) asis files supported (new module). [Robert Thau]
9963 *) IdentityCheck code is compiled in, but has not been tested. (I
9964 don't know anyone who runs identd). [Robert Thau]
9966 *) PATH_INFO and PATH_TRANSLATED are not set unless some real PATH_INFO
9967 came in with the request, for NCSA bug-compatibility. [Robert Thau]
9969 *) Don't leak the DIR * on HEAD request for a directory. [Robert Thau]
9971 *) Deleted the block_alarms() stuff from dbm_auth; no longer necessary,
9972 as timeouts are not in scope. [Robert Thau]
9974 *) quoted-string args in config files now handled correctly (doesn't drop
9975 the last character). [Robert Thau; reported by Randy Terbush]
9977 *) Fixed silly typo in http_main.c which was suddenly fatal in HP-UX.
9978 How the hell did it ever work? [Robert Thau; reported by Rob Hartill]
9980 *) mod_core.c --- default_type returns DEFAULT_TYPE (the compile-time
9981 default default type); the former default default behavior when all
9982 type-checkers defaulted had been a core dump. [Paul Sutton]
9984 *) Copy filenames out of the struct dirent when indexing
9985 directories. (On Linux, readdir() returns a pointer to the same
9986 memory area every time). Fix is in mod_dir.c. [Paul Sutton]
9988 Changes with Shambhala 0.5.3 [not released]
9990 *) Default response handler notes "file not found" in the error log,
9991 if the file was not found. [Cliff Skolnick].
9993 *) Another Cliff bug --- "GET /~user" now properly redirects (the userdir
9994 code no longer sets up bogus PATH_INFO which fakes out the directory
9995 handler). [Cliff Skolnick]
9997 Changes with Shambhala 0.5.2 06 Jul 1995
9999 *) Changes to http_main.c --- root server no longer plays silly
10000 games with SIGCHLD, and so now detects and replaces dying
10001 children. Child processes just die on SIGTERM, without taking
10002 the whole process group with them. Potential problem --- if any
10003 child process refuses to die, we hang in restart.
10004 MaxRequestsPerChild may still not work, but it certainly works
10005 better than it did before this! [Robert Thau]
10007 *) mod_dir.c bug fixes: ReadmeName and HeaderName
10008 work (or work better, at least); over-long description lines
10009 properly terminated. [Mark Cox]
10011 *) http_request.c now calls unescape_url() more places where it
10012 should [Paul Sutton].
10014 *) More directory handling bugs (reported by Cox)
10015 Parent Directory link is now set correctly. [Robert Thau]
10017 Changes with Shambhala 0.5.1 04 Jul 1995
10019 *) Generalized cleanup interface in alloc.c --- any function can be
10020 registered with alloc.c as a cleanup for a resource pool;
10021 tracking of files and file descriptors has been reimplemented in
10022 terms of this interface, so I can give it some sort of a test.
10025 *) More changes in alloc.c --- new cleanup_for_exec() function,
10026 which tracks down and closes all file descriptors which have been
10027 registered with the alloc.c machinery before the server exec()s a
10028 child process for CGI or <!--#exec-->. CGI children now get
10029 started with exactly three file descriptors open. Hopefully,
10030 this cures the problem Rob H. was having with overly persistent
10031 CGI connections. [Robert Thau]
10033 *) Mutual exclusion around the accept() in child_main() --- this is
10034 required on at least SGI, Solaris and Linux, and is #ifdef'ed in
10035 by default on those systems only (-DFCNTL_SERIALIZED_ACCEPT).
10036 This uses fcntl(F_SETLK,...) on the error log descriptor because
10037 flock() on that descriptor won't work on systems which have BSD
10038 flock() semantics, including (I think) Linux 1.3 and Solaris.
10040 This does work on SunOS (when the server is idle, only one
10041 process in the pool is waiting on accept()); it *ought* to work
10042 on the other systems. [Robert Thau]
10044 *) FreeBSD and BSDI portability tweaks [Chuck Murcko]
10046 *) sizeof(*sa_client) bugfix from [Rob Hartill]
10048 *) pstrdup(..., NULL) returns NULL, [Randy Terbush]
10050 *) block_alarms() to avoid leaking the DBM* in dbm auth (this should
10051 be unnecessary if I go to the revised timeout-handling scheme).
10054 *) For NCSA bug-compatibility, set QUERY_STRING env var (to a null
10055 string) even if none came in with the request. [Robert Thau]
10057 *) CHANGES file added to distribution ;-).
10059 Changes with Shambhala 0.4.5
10061 *) mod_dld --- early dynamic loading support [rst]
10062 *) Add wildcard content handlers for XBITHACK; default_hander now
10063 invoked with that mechanism (as a handler hanging off mod_core) [rst]
10064 *) XBITHACK supported as a wildcard content-handler, and
10065 configurable at run-time (not just at compile time, as in the
10066 "patchy server" releases) [rst]
10068 Changes with Shambhala 0.4.4 30 Jun 1995
10070 *) Fixed basic thinkos in mod_dbm_auth.c [rst, reported by Mark Cox]
10071 *) Handle Addtype x/y .z [rst, reported by Cox]
10073 Changes with Shambhala 0.4.3
10075 *) Fixed very dumb bug in mod_alias; "Alias" and "Redirect" are not
10076 synonymous [rst, terbush]
10078 Changes with Shambhala 0.4.1 28 Jun 1995
10080 *) First-cut virtual host implementation; some refit in the config
10081 reading code, and log management, was necessary to support this [rst]
10082 *) Sub-pool machinery, originally added to avoid excessive storage
10083 allocation on listings of large directories (which turned out to
10084 be the problem that the 0.3 storage accounting was added to
10085 find). Subrequests and mod_dir changed to use subpools. [rst]
10086 *) More memory debugging --- free list consistency checks. [rst]
10087 *) Added err_headers to request_rec, with support elsewhere [rst]
10088 *) Other fixes to minor bugs in mod_dir and mod_includes [rst, terbush]
10090 Changes with Shambhala 0.3 19 Jun 1995
10092 *) Switch ONE_PROCESS to a runtime command-line option (-X)
10093 *) Don't compile in mod_ai_backcompat by default
10094 *) Switch name of server from Apache to Shambhala in Makefile
10095 *) Add some accounting routines to track memory usage in the pools,
10098 Changes with Shambhala 0.2
10100 *) Set DOCUMENT_ROOT CGI variable
10101 *) Add single-process debugging, as a compile-time option (ONE_PROCESS)
10102 *) Add critical section protection to handling of cleanup structures
10104 *) Significant code reorg within the server core to group related
10105 functions together [rst]
10106 *) Correctly handle clients that hang up before sending any request
10108 *) Replace dying child processes. [rst]
10110 Changes with Shambhala 0.1 12 Jun 1995
10112 Major rewrite of the pre-existing "patchy server" codebase, by
10113 Robert Thau (rst). Significant portions of the server code, such
10114 as configuration-file handling and HTTP authentication support,
10115 were ripped out and rewritten from scratch. Code that was not
10116 completely rewritten was significantly altered.
10118 Major changes with this release include:
10120 *) Introduction of the module API; in request handling, the central
10121 machinery just dispatches to various modules, which actually do
10122 most of the work. Configuration handling is similar --- modules
10123 declare their own commands, and the central machinery just
10124 dispatches to them.
10126 API features from shambhala/0.1 were substantially unchanged in
10127 Apache 1.0 and 1.1. (1.0 API features not yet present in this
10128 release, such as wildcard handlers and subpools, were added in
10129 subsequent Shambhala releases, and were also generally rst's
10132 *) This release included the following modules:
10134 mod_access (access control --- allow and deny directives),
10135 mod_alias (Alias and Redirect commands),
10136 mod_auth (straight HTTP authentication, based on flat-files)
10137 mod_auth_dbm (same, with dbm files)
10138 mod_cgi (CGI scripts and, in this release, ScriptAlias)
10139 mod_common_log (CLF access logs; later renamed mod_log_common)
10140 mod_dir (directory indexing)
10141 mod_include (server-side includes)
10142 mod_mime (AddType directives)
10143 mod_negotiation (content negotiation)
10144 mod_userdir (support for users' public_html directories)
10146 It also included a mod_ai_backcompat, which was a private hack
10147 for back-compatibility with rst's own AI-lab servers.
10149 All of these modules were substantially complete, and functional
10150 or nearly so (a few, which implemented features not in use at
10151 Thau's site, required patches of a few lines).
10153 *) sub-request machinery, to allow modules to determine how other
10154 modules would assign MIME types to a given file, or optionally
10155 serve its content (this is heavily used by mod_dir, mod_include
10156 and mod_negotiation).
10158 *) Resource pool system for keeping track of memory allocated and
10159 files opened in service of a particular request. Much of the
10160 code in the modules (when they weren't rewrites) was adjusted to
10161 replace a pervasive convention of using fixed-size buffers on
10162 the stack with an equally pervasive convention of using memory
10163 allocated with palloc().
10165 *) Reorganization of data structures associated with a given
10166 request to eliminate use of global variables and the troublesome
10167 unmunge_name function (used in NCSA and early Apache releases to
10168 attempt to determine the URI which mapped to a given filename
10169 --- a difficult proposition, given that it is easy to produce
10170 setups in which multiple URIs map to the same file).
10172 *) Source files renamed and rearranged
10174 *) Very simple pre-forking behavior --- parent process forked off a
10175 fixed number of children, and then just waited for SIGHUP.
10177 *) Other more minor changes too numerous to list.
10179 This release included modified versions of a lot of code from the
10180 Apache 0.6.4 public release, plus an early pre-forking patch
10181 codeveloped by Robert Thau and Rob Hartill.
10183 Changes with Apache 0.7.3 20 Jun 1995
10185 *) There were a bunch of changes between Apache 0.6.4 and 0.7.3 that
10186 were incorporated by Rob Hartill on the main branch while Robert Thau
10187 worked on the Shambhala rewrite above. Most were merged into the
10188 Shambala architecture after Apache 0.8.0.
10190 Changes with Apache 0.6.4 13 May 1995
10192 *) Patches by Rob Hartill, Cliff Skolnick, Randy Terbush, Robert Thau,
10195 Changes with Apache 0.5.1 10 Apr 1995
10197 Changes with Apache 0.4 02 Apr 1995
10199 *) Patches by Brian Behlendorf, Andrew Wilson, Robert Thau,
10202 Changes with Apache 0.3 24 Mar 1995
10204 *) Patches by Robert Thau, David Robinson, Rob Hartill, and
10207 Changes with Apache 0.2 18 Mar 1995
10209 *) Based on NCSA httpd 1.3 by Rob McCool and patches by CERT,
10210 Roy Fielding, Robert Thau, Nicolas Pioch, David Robinson,
10211 Brian Behlendorf, Rob Hartill, and Cliff Skolnick.
