22 *) mime.types: add registered Apple installer type
23 PR 40379 [Peter Bierman <pmb+apache apple.com>]
25 *) mod_ldap, mod_authnzldap: Add support for nested groups (i.e. the ability
26 to authorize an authenticated user via a "require ldap-group X" directive
27 where the user is not in group X, but is in a subgroup contained in X.
28 PR 42891 [Paul J. Reder]
30 *) mod_deflate: don't try to process metadata buckets as data. what should
31 have been a 413 error was logged as a 500 and a blank screen appeared
33 [Greg Ames, Ruediger Pluem]
35 *) SECURITY: CVE-2007-3304 (cve.mitre.org)
36 prefork, worker, event MPMs: Ensure that the parent process cannot
37 be forced to kill processes outside its process group. [Joe Orton]
39 *) SECURITY: CVE-2006-5752 (cve.mitre.org)
40 mod_status: Fix a possible XSS attack against a site with a public
41 server-status page and ExtendedStatus enabled, for browsers which
42 perform charset "detection". Reported by Stefan Esser. [Joe Orton]
44 *) Event MPM: Add support for running under mod_ssl, by reverting to the
45 Worker MPM behaviors, when run under an input filter that buffers
46 its own data. [Paul Querna]
48 *) mod_ssl: Add support for caching SSL Sessions in memcached. [Paul Querna]
50 *) SECURITY: CVE-2007-1862 (cve.mitre.org)
51 mod_mem_cache: Copy headers into longer lived storage; header names and
52 values could previously point to cleaned up storage
53 PR 41551 [Davi Arnaut <davi haxent.com.br>]
55 *) mod_cache: Do not set Date or Expires when they are missing from
56 the original response or are invalid. [Justin Erenkrantz]
58 *) mod_cache: Correctly handle HEAD requests on expired cache content.
59 PR 41230. [Niklas Edmundsson]
61 *) mod_proxy: Added ProxyPassMatch directive, which is similar
62 to ProxyPass but takes a regex local path prefix. [Jim Jagielski]
64 *) mod_so: Solve dev's confusion by reporting expected/seen module
65 magic signatures when failing with a 'garbled' message, and solve
66 user's confusion by pointing out 'perhaps compiled for a different
67 version of apache?'. [William Rowe]
69 *) mod_ssl: Version reporting update; displays 'compiled against'
70 Apache and build-time SSL Library versions at loglevel [info],
71 while reporting the run-time SSL Library version in the server
72 info tags. Helps to identify a mod_ssl built against one flavor
73 of OpenSSL but running against another (also adds SSL-C version
74 number reporting.) [William Rowe]
76 *) core: Change etag generation to produce identical results on
77 32-bit and 64-bit platforms. PR 40064. [Joe Orton]
79 *) ab: Add -r option to continue after socket receive errors.
80 [Filip Hanik <devlist hanik.com>]
82 *) mod_ldap: Fix the search limit parameter to ldap_search_ext_s()
83 for SDKs that define LDAP_NO_LIMIT to something other than -1.
84 [David Jones <oscaremma gmail.com>]
86 *) mod_dbd: Introduce configuration groups to allow inheritance by virtual
87 hosts of database configurations from the main server. Determine the
88 minimal set of distinct configurations and share connection pools
89 whenever possible. Allow virtual hosts to override inherited SQL
90 statements. PR 41302. [Chris Darroch]
92 *) core: Fix broken chunk filtering that causes all non blocking reads to be
93 converted into blocking reads. PR 41056. [Jean-Frederic Clere, Jim Jagielski]
95 *) apxs: Enhance -q flag to print all known variables and their values
96 when invoked without variable name(s).
97 [William Rowe, Sander Temme]
99 *) mod_dbd: Create memory sub-pools for each DB connection and close
100 DB connections in a pool cleanup function. Ensure prepared statements
101 are destroyed before DB connection is closed. When using reslists,
102 prevent segfaults when child processes exit, and stop memory leakage
103 of ap_dbd_t structures. Avoid use of global s->process->pool, which
104 isn't destroyed by exiting child processes in most multi-process MPMs.
105 PR 39985. [Chris Darroch, Nick Kew]
107 *) apxs: Eliminate run-time check for mod_so. PR 40653.
108 [David M. Lee <dmlee crossroads.com>]
110 *) beos MPM: Create pmain pool and run modules' child_init hooks when
111 entering ap_mpm_run(), then destroy pmain when exiting ap_mpm_run().
114 *) netware MPM: Destroy pmain pool when exiting ap_mpm_run() so that
115 cleanups registered in modules' child_init hooks are performed.
118 *) mod_dbd: Handle error conditions in dbd_construct() properly.
119 Simplify ap_dbd_open() and use correct arguments to apr_dbd_error()
120 when non-threaded. Register correct cleanup data in non-threaded
121 ap_dbd_acquire() and ap_dbd_cacquire(). Clean up configuration data
122 and merge function. Use ap_log_error() wherever possible.

125 *) core: Do not replace a Date header set by a proxied backend server.
126 PR 40232. [Ruediger Pluem]

132 *) mod_cache: Remove expired content from cache that cannot be revalidated.
133 PR 30370. [Ruediger Pluem]
135 *) mod_dbd: Stash DBD connections in request_config of initial request
136 only, or else sub-requests and internal redirections may cause
137 entire DBD pool to be stashed in a single HTTP request. [Chris Darroch]
139 *) mod_proxy: Add a missing assignment in an error checking code path.
140 PR 40865. [Andrew Rucker Jones <arjones simultan.dyndns.org>]
142 *) mod_mem_cache: Increase the minimum and default value for
143 MCacheMinObjectSize from 0 to 1, as a MCacheMinObjectSize of 0 does not
144 make sense and leads to a division by zero. PR 40576.

147 *) Fix issue which could cause error messages to be written to access logs
148 on Win32. PR 40476. [Tom Donovan <Tom.Donovan acm.org>]
150 *) The LockFile directive, which specifies the location of
151 the accept() mutex lockfile, is deprecated. Instead, the
152 AcceptMutex directive now takes an optional lockfile
153 location parameter, ala SSLMutex. [Jim Jagielski]
155 *) mod_authn_dbd: Export any additional columns queried in the SQL select
156 into the environment with the name AUTHENTICATE_<COLUMN>. This brings
157 mod_authn_dbd behaviour in line with mod_authnz_ldap. [Graham Leggett]
159 *) mod_dbd: Key the storage of prepared statements on the hex string
160 value of server_rec, rather than the server name, as the server name
161 may change (eg when the server name is set) at any time, causing
162 weird behaviour in modules dependent on mod_dbd. [Graham Leggett]
164 *) mod_proxy_fcgi: Added win32 build. [Mladen Turk]
166 *) sendfile_nonblocking() takes the _brigade_ as an argument, gets
167 the first bucket from the brigade, finds it not to be a FILE
168 bucket and barfs. The fix is to pass a bucket rather than a brigade.
169 [Niklas Edmundsson <nikke acc.umu.se>]
171 *) mod_rewrite: support rewritemap by SQL query [Nick Kew]
173 *) ap_get_server_version() has been removed. Third-party modules must
174 now use ap_get_server_banner() or ap_get_server_description().
177 *) All MPMs: Introduce a check_config phase between pre_config and
178 open_logs, to allow modules to review interdependent configuration
179 directive values and adjust them while messages can still be logged
180 to the console. Handle relevant MPM directives during this phase
181 and format messages for both the console and the error log, as
182 appropriate. [Chris Darroch]
184 *) mod_proxy: don't URLencode tilde in path component
185 [Stijn Hoop <stijn sandcat.nl>]
187 *) mpm_winnt: Fix return values from wait_for_many_objects.
188 The return value is index to the signaled thread in the
189 creted_threads array. We can not use WAIT_TIMEOUT because
190 his value is defined as 258, thus limiting the MaxThreads
191 to that value. [Mladen Turk]
193 *) core: Do not allow internal redirects like the DirectoryIndex of mod_dir
194 to circumvent the symbolic link checks imposed by FollowSymLinks and
195 SymLinksIfOwnerMatch. [Nick Kew, Ruediger Pluem, William Rowe]
197 *) mod_proxy: Support environment variable interpolation in reverse
198 proxying directives. [Nick Kew]
200 *) core: Add the filename of the configuration file to the warning message
201 about the useless use of AllowOverride. PR 39992.
202 [Darryl Miles <darryl darrylmiles.org>]
204 *) New SSLLogLevelDebugDump [ None (default) | IO (not bytes) | Bytes ]
205 configures the I/O Dump of SSL traffic, when LogLevel is set to Debug.
206 The default is none as this is far greater debugging resolution than
207 the typical administrator is prepared to untangle. [William Rowe]
209 *) mod_disk_cache: If possible, check if the size of an object to cache is
210 within the configured boundaries before actually saving data.
211 [Niklas Edmundsson <nikke acc.umu.se>]
213 *) mod_cache: Convert all values to seconds before comparing them when
214 checking whether to send a Warning header for a stale response.
215 PR 39713. [Owen Taylor <otaylor redhat.com>]
217 *) mod_disk_cache: Delete temporary files if they cannot be renamed to their
218 final name. [Davi Arnaut <davi haxent.com.br>]
220 *) Worker and event MPMs: Remove improper scoreboard updates which were
221 performed in the event of a fork() failure. [Chris Darroch]
223 *) Add support for fcgi:// proxies to mod_rewrite.
224 [Markus Schiegl <ms schiegl.com>]
226 *) Remove incorrect comments from scoreboard.h regarding conditional
227 loading of worker_score structure with mod_status, and remove unused
228 definitions relating to old life_status field.
229 [Chris Darroch <chrisd pearsoncmg.com>]
231 *) Remove allocation of memory for unused array of lb_score pointers
232 in ap_init_scoreboard(). [Chris Darroch <chrisd pearsoncmg.com>]
234 *) Add mod_proxy_fcgi, a FastCGI back end for mod_proxy.
235 [Garrett Rooney, Jim Jagielski, Paul Querna]
237 *) Event MPM: Fill in the scoreboard's tid field. PR 38736.
238 [Chris Darroch <chrisd pearsoncmg.com>]
240 *) mod_charset_lite: Remove Content-Length when output filter can
241 invalidate it. Warn when input filter can invalidate it.
244 *) mod_ssl: Fix spurious hostname mismatch warning for valid
245 wildcard certificates. PR 37911. [Nick Burch <nick torchbox.com>]
247 *) Authz: Add the new module mod_authn_core that will provide common
248 authn directives such as 'AuthType', 'AuthName'. Move the directives
249 'AuthType' and 'AuthName' out of the core module and merge mod_authz_alias
250 into mod_authn_core. [Brad Nicholes]
252 *) Authz: Move the directives 'Order', 'Allow', 'Deny' and 'Satisfy'
253 into the new module mod_access_compat which can be loaded to provide
254 support for these directives.
257 *) Authz: Move the 'Require' directive from the core module as well as
258 add the directives '<SatisfyAll>', '<SatisfyOne>', '<RequireAlias>'
259 and 'Reject' to mod_authz_core. The new directives introduce 'AND/OR'
260 logic into the authorization processing. [Brad Nicholes]
262 *) Authz: Add the new module mod_authz_core which acts as the
263 authorization provider vector and contains common authz
264 directives. [Brad Nicholes]
266 *) Authz: Renamed mod_authz_dbm authz providers from 'group' and
267 'file-group' to 'dbm-group' and 'dbm-file-group'. [Brad Nicholes]
269 *) Authz: Added the new authz providers 'env', 'ip', 'host', 'all' to handle
270 host-based access control provided by mod_authz_host and invoked
271 through the 'Require' directive. [Brad Nicholes]
273 *) Authz: Convert all of the authz modules from hook based to
274 provider based. [Brad Nicholes]
276 *) mod_cache: Add CacheMinExpire directive to set the minimum time in
277 seconds to cache a document.
278 [Brian Akins <brian.akins turner.com>, Ruediger Pluem]
280 *) mod_authz_dbd: SQL authz with Login/Session support [Nick Kew]
282 *) Fix typo in ProxyStatus syntax error message.
283 [Christophe Jaillet <christophe.jaillet wanadoo.fr>]
285 *) Asynchronous write completion for the Event MPM. [Brian Pane]
287 *) Added an End-Of-Request bucket type. The logging of a request and
288 the freeing of its pool are now done when the EOR bucket is destroyed.
289 This has the effect of delaying the logging until right after the last
290 of the response is sent; ap_core_output_filter() calls the access logger
291 indirectly when it destroys the EOR bucket. [Brian Pane]
293 *) Rewrite of logresolve support utility: IPv6 addresses are now supported
294 and the format of statistical output has changed. [Colm MacCarthaigh]
296 *) Rewrite of ap_coreoutput_filter to do nonblocking writes [Brian Pane]
298 *) Added new connection states for handler and write completion
301 *) mod_cgid: Refuse to work on Solaris 10 due to OS bugs. PR 34264.
304 *) Teach mod_ssl to use arbitrary OIDs in an SSLRequire directive,
305 allowing string-valued client certificate attributes to be used for
306 access control, as in: SSLRequire "value" in OID("1.3.6.1.4.1.18060.1")

347 *) mod_cache: Use the same cache key throughout the whole request processing
348 to handle escaped URLs correctly. PR 41475. [Ruediger Pluem]
350 *) mod_cache: Add CacheIgnoreQueryString directive. PR 41484.
351 [Fredrik Widlund <fredrik.widlund qbrick.com>]
353 *) mod_cache: While serving a cached entity ensure that filters that have
354 been applied to this cached entity before saving it to the cache are not
355 applied again. PR 40090. [Ruediger Pluem]
357 *) mod_cache: Correctly cache objects whose URL query string has been
358 modified by mod_rewrite. PR 40805. [Ruediger Pluem]
360 *) mod_proxy_http: Change handling of ProxyErrorOverride such that
361 3xx responses are no longer over-ridden (handling of 4xx and 5xx
362 responses is unchanged). PR 39245.
363 [Jeff Trawick, Bart van der Schans <schans hippo.nl>]
365 *) htdbm: Enable crypt support on platforms with crypt() but not
366 <crypt.h>, such as z/OS. [David Jones <oscaremma gmail.com>]
368 *) mod_ssl: initialize thread locks before initializing the hardware
369 acceleration library, so the latter can make use of the former.
370 PR 20951. [adunn at ncipher.com]
372 *) ab.c: Correct behavior of HTTP request headers sent by ab
373 in presence of -H command-line overrides. PR 31268, 26554.
374 [Arvind Srinivasan <arvind.srinivasan sun.com>]
376 *) ab.c: The apr_port_t type is unsigned, but ab was using a
377 signed format code in its reports. PR 42070.

380 *) core: Correct a regression since 2.0.x in the handling of AllowOverride
381 Options. PR 41829. [Torsten Förtsch <torsten.foertsch gmx.net>]
383 *) mod_proxy_http: Handle request bodies larger than 2 GB by converting
384 the Content-Length header of the request correctly. PR 40883.
385 [Ruediger Pluem, toadie <toadie643 gmail.com>]
387 *) mod_proxy: Fix some proxy setting inheritance problems (eg:
388 ProxyTimeout). PR 11540. [Stuart Children <stuart terminus.co.uk>]
390 *) Unix MPMs: Catch SIGFPE so that exception hooks and CoreDumpDirectory
391 can work after that terminating signal.
392 [Eric Covener <covener gmail.com>]
394 *) Win32: Makefile.win will now build with MS VC 8 (Visual Studio 2005)
395 including embedding the .manifest information into each binary.
398 Changes with Apache 2.2.4
400 *) mod_isapi: Correctly present SERVER_PORT_SECURE.

424 *) Better detection and clean up of ldap connection that has been
425 terminated by the ldap server. PR 40878.
426 [Rob Baily <rbaily servicebench com>]
428 *) mod_mem_cache: Convert mod_mem_cache to use APR memory pool functions
429 by creating a root pool for object persistence across requests. This
430 also eliminates the need for custom serialization code.
431 [Davi Arnaut <davi haxent.com.br>]
433 *) mod_authnz_ldap: Add an AuthLDAPRemoteUserAttribute directive. If
434 set, REMOTE_USER will be set to this attribute, rather than the
435 username supplied by the user. Useful for example when you want users
436 to log in using an email address, but need to supply a userid instead
437 to the backend. [Graham Leggett]
439 *) mod_cgi and mod_cgid: Don't use apr_status_t error return
440 from input filters as HTTP return value from the handler.
443 *) mod_cache: Eliminate a bogus error in the log when a filter returns
444 AP_FILTER_ERROR. [Niklas Edmundsson <nikke acc.umu.se>]
446 *) core: Fix issue which could cause piped loggers to be orphaned and never
447 terminate after a graceful restart. PR 40651. [Joe Orton, Ruediger Pluem]
449 *) core: Fix address-in-use startup failure caused by corruption of the list
450 of listen sockets in some configurations with multiple generic Listen
451 directives. [Jeff Trawick]
453 *) mod_headers: Support regexp-based editing of HTTP headers. [Nick Kew]
455 *) mod_proxy: Add explicit flushing feature. When Servlet container sends AJP
456 body message with size 0, this means that Servlet container has asked for
457 an explicit flush. Create flush bucket in that case. This feature has been
458 added to the recent Tomcat versions without breaking the AJP protocol.
461 *) mod_proxy_balancer: Set the new environment variable BALANCER_ROUTE_CHANGED
462 if a worker with a route different from the one supplied by the client
463 had been chosen or if the client supplied no routing information for
464 a balancer with sticky sessions. [Ruediger Pluem]

467 and the worker used during a request as environment variables. PR 39806.

474 parameter in the URL correctly. PR 40400.
475 [Ruediger Pluem, Tomokazu Harada <harada sysrdc.ns-sol.co.jp>]
477 *) mod_proxy_ajp: Added cping/cpong support for the AJP protocol.
478 A new worker directive ping=timeout will cause CPING packet
479 to be send expecting CPONG packet within defined timeout.
480 In case the backend is too busy this will fail instead
481 sending the full header. [Mladen Turk]
483 *) mod_cache: From RFC3986 (section 6.2.3.) if a URI contains an
484 authority component and an empty path, the empty path is to be equivalent
485 to "/". It explicitly cites the following four URIs as equivalents:
489 http://example.com:80/
490 [Davi Arnaut <davi haxent.com.br>]
492 *) mod_cache: Don't cache requests with a expires date in the past;
493 otherwise mod_cache will always try to cache the URL. This bug
494 might lead to numerous rename() errors on win32 if the URL was
495 previously cached. [Davi Arnaut <davi haxent.com.br>]
497 *) mod_disk_cache: Make sure that only positive integers are accepted
498 for the CacheMaxFileSize and CacheMinFileSize parameters in the
499 config file. PR39380. [Niklas Edmundsson <nikke acc.umu.se>]
501 *) core: Deal with the widespread use of apr_status_t return values
502 as HTTP status codes, as documented in PR#31759 (a bug shared by
503 the default handler, mod_cgi, mod_cgid, mod_proxy, and probably
504 others). PR31759. [Jeff Trawick, Ruediger Pluem, Joe Orton]
506 *) mod_ext_filter: Handle filter names which include capital letters.

533 of the ServerTokens directive. ap_get_server_version() is now
534 deprecated, and is replaced by ap_get_server_banner() and
535 ap_get_server_description(). [Jeff Trawick]
537 *) mod_proxy_balancer: Workers can now be defined as part of
538 a balancer cluster "set" in which members of a lower-numbered set
539 are preferred over higher numbered ones. [Jim Jagielski]
541 *) mod_proxy_balancer: Workers can now be defined as "hot standby" which
542 will only be used if all other workers are unusable (eg: in
543 error or disabled). Also, the balancer-manager displays the election
