3 Changes with Apache 2.3.13
5 *) mod_authnz_ldap: If the LDAP server returns constraint violation,
6 don't treat this as an error but as "auth denied". [Stefan Fritsch]
8 *) mod_proxy_fcgi|scgi: Add support for "best guess" of PATH_INFO
9 for SCGI/FCGI. PR 50880, 50851. [Mark Montague <mark catseye.org>,
12 *) mod_cache: When content is served stale, and there is no means to
13 revalidate the content using ETag or Last-Modified, and we have
14 mandated no stale-on-error behaviour, stand down and don't cache.
15 Saves a cache write that will never be read.
18 *) mod_reqtimeout: Fix a timed out connection going into the keep-alive
19 state after a timeout when discarding a request body. PR 51103.
22 *) core: Add various file existance test operators to ap_expr.
25 *) mod_proxy_express: New mass reverse-proxy switch extension for
26 mod_proxy. [Jim Jagielski]

39 [Scott Hill <shill genscape.com>]
41 *) support: Make sure check_forensic works with mod_unique_id loaded
44 *) Add child_status hook for tracking creation/termination of MPM child
45 processes. Add end_generation hook for notification when the last
46 MPM child of a generation exits. [Jeff Trawick]
48 *) mod_ldap: Make LDAPSharedCacheSize 0 create a non-shared-memory cache per
49 process as opposed to disabling caching completely. This allows to use
50 the non-shared-memory cache as a workaround for the shared memory cache
51 not being available during graceful restarts. PR 48958. [Stefan Fritsch]
53 *) Add new ap_reserve_module_slots/ap_reserve_module_slots_directive API,
54 necessary if a module (like mod_perl) registers additional modules late
55 in the startup phase. [Stefan Fritsch]
57 *) core: Prevent segfault if DYNAMIC_MODULE_LIMIT is reached. PR 51072.

65 *) core: Support module names with colons in loglevel configuration.
66 [Torsten Förtsch <torsten foertsch gmx net>]
68 *) mod_ssl, ab: Support OpenSSL compiled without SSLv2 support.
71 *) core: Abort if the MPM is changed across restart. [Jeff Trawick]
73 *) mod_proxy_ajp: Add support for 'ProxyErrorOverride on'. PR 50945.
74 [Peter Pramberger <peter pramberger.at>, Jim Jagielski]
76 *) mod_proxy_fcgi: Add support for 'ProxyErrorOverride on'. PR 50913.
77 [Mark Montague <mark catseye.org>, Jim Jagielski]
79 *) core: Change the APIs of ap_cfg_getline() and ap_cfg_getc() to return an
80 error code. Abort with a nice error message if a config line is too long.
81 Partial fix for PR 50824. [Stefan Fritsch]
83 *) mod_info: Dump config to stdout during startup if -DDUMP_CONFIG is
84 specified. PR 31956. [Stefan Fritsch]
86 *) Restore visibility of DEFAULT_PIDLOG to core and modules. MPM
87 helper function ap_remove_pid() added. [Jeff Trawick]
89 *) Enable DEFAULT_REL_RUNTIMEDIR on Windows and NetWare. [various]
91 *) Correct C++ incompatibility with http_log.h. [Stefan Fritsch, Jeff
94 *) mod_log_config: Prevent segfault. PR 50861. [Torsten Förtsch
95 <torsten.foertsch gmx.net>]
97 *) core: AllowEncodedSlashes new option NoDecode to allow encoded slashes
98 in request URL path info but not decode them. Change behavior of option
99 "On" to decode the encoded slashes as 2.0 and 2.2 do. PR 35256,
100 PR 46830. [Dan Poirier]
102 *) mod_ssl: Check SNI hostname against Host header case-insensitively.
103 PR 49491. [Mayank Agrawal <magrawal.08 gmail.com>]
105 *) mod_ldap: Add LDAPConnectionPoolTTL to give control over lifetime
106 of bound backend LDAP connections. PR47634 [Eric Covener]
108 *) mod_cache: Make CacheEnable and CacheDisable configurable per
109 directory in addition to per server, making them work from within
110 a LocationMatch. [Graham Leggett]
112 *) worker, event, prefork: Correct several issues when built as
113 DSOs; most notably, the scoreboard was reinitialized during graceful
114 restart, such that processes of the previous generation were not
115 observable. [Jeff Trawick]
117 Changes with Apache 2.3.11
119 *) mod_win32: Added shebang check for '! so that .vbs scripts work as CGI.
120 Win32's cscript interpreter can only use a single quote as comment char.
123 *) mod_proxy: balancer-manager now uses POST instead of GET.
126 *) core: new util function: ap_parse_form_data(). Previously,
127 this capability was tucked away in mod_request. [Jim Jagielski]
129 *) core: new hook: ap_run_pre_read_request. [Jim Jagielski]
131 *) mod_cache: When a request other than GET or HEAD arrives, we must
132 invalidate existing cache entities as per RFC2616 13.10. PR 15868.
135 *) modules: Fix many modules that were not correctly initializing if they
136 were not active during server startup but got enabled later during a
137 graceful restart. [Stefan Fritsch]
139 *) core: Create new ap_state_query function that allows modules to determine
140 if the current configuration run is the initial one at server startup,
141 and if the server is started for testing/config dumping only.
144 *) mod_proxy: Runtime configuration of many parameters for existing
145 balancers via the balancer-manager. [Jim Jagielski]
147 *) mod_proxy: Runtime addition of new workers (BalancerMember) for existing
148 balancers via the balancer-manager. [Jim Jagielski]
150 *) mod_cache: When a bad Expires date is present, we need to behave as if
151 the Expires is in the past, not as if the Expires is missing. PR 16521.
152 [Co-Advisor <coad@measurement-factory.com>]
154 *) mod_cache: We must ignore quoted-string values that appear in a
155 Cache-Control header. PR 50199. [Graham Leggett]
157 *) mod_dav: Revert change to send 501 error if unknown Content-* header is
158 received for a PUT request. PR 42978. [Stefan Fritsch]
160 *) mod_cache: Respect s-maxage as described by RFC2616 14.9.3, which must
161 take precedence if present. PR 35247. [Graham Leggett]
163 *) mod_ssl: Fix a possible startup failure if multiple SSL vhosts
164 are configured with the same ServerName and private key file.
165 [Masahiro Matsuya <mmatsuya redhat.com>, Joe Orton]
167 *) mod_socache_dc: Make module compile by fixing some typos.
168 PR 50735 [Mark Montague <mark catseye.org>]
170 *) prefork: Update MPM state in children during a graceful stop or
171 restart. PR 41743. [Andrew Punch <andrew.punch 247realmedia.com>]
173 *) mod_mime: Ignore leading dots when looking for mime extensions.
174 PR 50434 [Stefan Fritsch]
176 *) core: Add support to set variables with the 'Define' directive. The
177 variables that can then be used in the config using the ${VAR} syntax
178 known from envvar interpolation. [Stefan Fritsch]
180 *) mod_proxy_http: make adding of X-Forwarded-* headers configurable.
181 ProxyAddHeaders defaults to On. [Vincent Deffontaines]
183 *) mod_slotmem_shm: Increase memory alignment for slotmem data.
186 *) mod_ssl: Add config options for OCSP: SSLOCSPResponderTimeout,
187 SSLOCSPResponseMaxAge, SSLOCSPResponseTimeSkew.
188 [Kaspar Brand <httpd-dev.2011 velox.ch>]
190 *) mod_ssl: Revamp output buffering to reduce network overhead for
191 output fragmented into many buckets, such as chunked HTTP responses.
194 *) core: Apply <If> sections to all requests, not only to file base requests.
195 Allow to use <If> inside <Directory>, <Location>, and <Files> sections.
196 The merging of <If> sections now happens after the merging of <Location>
197 sections, even if an <If> section is embedded inside a <Directory> or
198 <Files> section. [Stefan Fritsch]
200 *) mod_proxy: Refactor usage of shared data by dropping the scoreboard
201 and using slotmem. Create foundation for dynamic growth/changes of
202 members within a balancer. Remove BalancerNonce in favor of a
203 per-balancer 'nonce' parameter. [Jim Jagielski]
205 *) mod_status: Don't show slots which are disabled by MaxClients as open.
206 PR: 47022 [Jordi Prats <jordi prats gmail com>, Stefan Fritsch]
208 *) mpm_prefork: Fix ap_mpm_query results for AP_MPMQ_MAX_DAEMONS and
211 *) mod_authz_core: Fix bug in merging logic if user-based and non-user-based
212 authorization directives were mixed. [Stefan Fritsch]
214 *) mod_authn_socache: change directive name from AuthnCacheProvider
215 to AuthnCacheProvideFor. The term "provider" is overloaded in
216 this module, and we should avoid confusion between the provider
217 of a backend (AuthnCacheSOCache) and the authn provider(s) for
218 which this module provides cacheing (AuthnCacheProvideFor).
221 *) mod_proxy_http: Allocate the fake backend request from a child pool
222 of the backend connection, instead of misusing the pool of the frontend
223 request. Fixes a thread safety issue where buckets set aside in the
224 backend connection leak into other threads, and then disappear when
225 the frontend request is cleaned up, in turn causing corrupted buckets
226 to make other threads spin. [Graham Leggett]
228 *) mod_ssl: Change the format of the SSL_{CLIENT,SERVER}_{I,S}_DN variables
229 to be RFC 2253 compatible, convert non-ASCII characters to UTF8, and
230 escape other special characters with backslashes. The old format can
231 still be used with the LegacyDNStringFormat argument to SSLOptions.
233 *) core, mod_rewrite: Make the REQUEST_SCHEME variable available to
234 scripts and mod_rewrite. [Stefan Fritsch]
236 *) mod_rewrite: Allow to use arbitrary boolean expressions (ap_expr) in
237 RewriteCond. [Stefan Fritsch]
239 *) mod_rewrite: Allow to unset environment variables using E=!VAR.
240 PR 49512. [Mark Drayton <mark markdrayton info>, Stefan Fritsch]
242 *) mod_headers: Restore the 2.3.8 and earlier default for the first
243 argument of the Header directive ("onsuccess"). [Eric Covener]
245 *) core: Disallow the mixing of relative and absolute Options PR 33708.
246 [Sönke Tesch <st kino-fahrplan.de>]
248 *) core: When exporting request headers to HTTP_* environment variables,
249 drop variables whose names contain invalid characters. Describe in the
250 docs how to restore the old behaviour. [Malte S. Stretz <mss apache org>]
252 *) core: When selecting an IP-based virtual host, favor an exact match for
253 the port over a wildcard (or omitted) port instead of favoring the one
254 that came first in the configuration file. [Eric Covener]
256 *) core: Overlapping virtual host address/port combinations now implicitly
257 enable name-based virtual hosting for that address. The NameVirtualHost
258 directive has no effect, and _default_ is interpreted the same as "*".
261 *) core: In the absence of any Options directives, the default is now
262 "FollowSymlinks" instead of "All". [Igor Galić]
264 *) rotatelogs: Add -e option to write logs through to stdout for optional
265 further processing. [Graham Leggett]
267 *) mod_ssl: Correctly read full lines in input filter when the line is
268 incomplete during first read. PR 50481. [Ruediger Pluem]
270 *) mod_authz_core: Add AuthzSendForbiddenOnFailure directive to allow
271 sending '403 FORBIDDEN' instead of '401 UNAUTHORIZED' if authorization
272 fails for an authenticated user. PR 40721. [Stefan Fritsch]
274 Changes with Apache 2.3.10
276 *) mod_rewrite: Don't implicitly URL-escape the original query string
277 when no substitution has changed it. PR 50447. [Eric Covener]
279 *) core: Honor 'AcceptPathInfo OFF' during internal redirects,
280 such as per-directory mod_rewrite substitutions. PR 50349.
283 *) mod_rewrite: Add 'RewriteOptions InheritBefore' to put the base
284 rules/conditions before the overridden rules/conditions. PR 39313.
285 [Jérôme Grandjanny <jerome.grandjanny cea.fr>]
287 *) mod_autoindex: add IndexIgnoreReset to reset the list of IndexIgnored
288 filenames in higher precedence configuration sections. PR 24243.
291 *) mod_cgid: RLimit* directive support for mod_cgid. PR 42135
294 *) core: Fail startup when the argument to ServerName looks like a glob
295 or a regular expression instead of a hostname (*?[]). PR 39863
296 [Rahul Nair <rahul.g.nair gmail.com>]
298 *) mod_userdir: Add merging of enable, disable, and filename arguments
299 to UserDir directive, leaving enable/disable of userlists unmerged.
300 PR 44076 [Eric Covener]
302 *) httpd: When no -k option is provided on the httpd command line, the server
303 was starting without checking for an existing pidfile. PR 50350
306 *) mod_proxy: Put the worker in error state if the SSL handshake with the
307 backend fails. PR 50332.
308 [Daniel Ruggeri <DRuggeri primary.net>, Ruediger Pluem]
310 *) mod_cache_disk: Fix Windows build which was broken after renaming
311 the module. [Gregg L. Smith]
313 Changes with Apache 2.3.9
315 *) SECURITY: CVE-2010-1623 (cve.mitre.org)
316 Fix a denial of service attack against mod_reqtimeout.
319 *) mod_headers: Change default first argument of Header directive
320 from "onsuccess" to "always". [Eric Covener]
322 *) mod_include: Add the onerror attribute to the include element,
323 allowing an URL to be specified to include on error. [Graham
326 *) mod_cache_disk: mod_disk_cache renamed to mod_cache_disk, to be
327 consistent with the naming of other modules. [Graham Leggett]
329 *) mod_setenvif: Add SetEnvIfExpr directive to set env var depending on
330 expression. [Stefan Fritsch]
332 *) mod_proxy: Fix ProxyPassInterpolateEnv directive. PR 50292.
335 *) suEXEC: Add Suexec directive to disable suEXEC without renaming the
336 binary (Suexec Off), or force startup failure if suEXEC is required
337 but not supported (Suexec On). Change SuexecUserGroup to fail
338 startup instead of just printing a warning if suEXEC is disabled.
341 *) core: Add Error directive for aborting startup or htaccess processing
342 with a specified error message. [Jeff Trawick]
344 *) mod_rewrite: Fix the RewriteEngine directive to work within a
345 location. Previously, once RewriteEngine was switched on globally,
346 it was impossible to switch off. [Graham Leggett]
348 *) core, mod_include, mod_ssl: Move the expression parser derived from
349 mod_include back into mod_include. Replace ap_expr with a parser
350 derived from mod_ssl's parser. Make mod_ssl use the new parser. Rework
351 ap_expr's public interface and provide hooks for modules to add variables
352 and functions. [Stefan Fritsch]
354 *) core: Do the hook sorting earlier so that the hooks are properly sorted
355 for the pre_config hook and during parsing the config. [Stefan Fritsch]
357 *) core: In the absence of any AllowOverride directives, the default is now
358 "None" instead of "All". PR49823 [Eric Covener]
360 *) mod_proxy: Don't allow ProxyPass or ProxyPassReverse in
361 <Directory> or <Files>. PR47765 [Eric Covener]
363 *) prefork/worker/event MPMS: default value (when no directive is present)
364 of MaxConnectionsPerChild/MaxRequestsPerChild is changed to 0 from 10000
365 to match default configuration and manual. PR47782 [Eric Covener]
367 *) proxy_connect: Don't give up in the middle of a CONNECT tunnel
368 when the child process is starting to exit. PR50220. [Eric Covener]
370 *) mod_autoindex: Fix inheritance of mod_autoindex directives into
371 contexts that don't have any mod_autoindex directives. PR47766.
374 *) mod_rewrite: Add END flag for RewriteRule to prevent further rounds
375 of rewrite processing when a per-directory substitution occurs.
378 *) mod_ssl: Make sure to always log an error if loading of CA certificates
379 fails. PR 40312. [Paul Tiemann <issues apache org ourdetour com>]
381 *) mod_dav: Send 501 error if unknown Content-* header is received for a PUT
382 request (RFC 2616 9.6). PR 42978. [Stefan Fritsch]
384 *) mod_dav: Send 400 error if malformed Content-Range header is received for
385 a put request (RFC 2616 14.16). PR 49825. [Stefan Fritsch]
387 *) mod_proxy: Release the backend connection as soon as EOS is detected,
388 so the backend isn't forced to wait for the client to eventually
389 acknowledge the data. [Graham Leggett]
391 *) mod_proxy: Optimise ProxyPass within a Location so that it is stored
392 per-directory, and chosen during the location walk. Make ProxyPass
393 work correctly from within a LocationMatch. [Graham Leggett]
395 *) core: Fix segfault if per-module LogLevel is on virtual host
396 scope. PR 50117. [Stefan Fritsch]
398 *) mod_proxy: Move the ProxyErrorOverride directive to have per
399 directory scope. [Graham Leggett]
401 *) mod_allowmethods: New module to deny certain HTTP methods without
402 interfering with authentication/authorization. [Paul Querna,
403 Igor Galić, Stefan Fritsch]
405 *) mod_ssl: Log certificate information and improve error message if client
406 cert verification fails. PR 50093, PR 50094. [Lassi Tuura <lat cern ch>,
409 *) htcacheclean: Teach htcacheclean to limit cache size by number of
410 inodes in addition to size of files. Prevents a cache disk from
411 running out of space when many small files are cached.
414 *) core: Rename MaxRequestsPerChild to MaxConnectionsPerChild, which
415 describes more accurately what the directive does. The old name
416 still works but logs a warning. [Stefan Fritsch]
418 *) mod_cache: Optionally serve stale data when a revalidation returns a
419 5xx response, controlled by the CacheStaleOnError directive.
422 *) htcacheclean: Allow the listing of valid URLs within the cache, with
423 the option to list entry metadata such as sizes and times. [Graham
426 *) mod_cache: correctly parse quoted strings in cache headers.
429 *) mod_cache: Allow control over the base URL of reverse proxied requests
430 using the CacheKeyBaseURL directive, so that the cache key can be
431 calculated from the endpoint URL instead of the server URL. [Graham
434 *) mod_cache: CacheLastModifiedFactor, CacheStoreNoStore, CacheStorePrivate,
435 CacheStoreExpired, CacheIgnoreNoLastMod, CacheDefaultExpire,
436 CacheMinExpire and CacheMaxExpire can be set per directory/location.
439 *) mod_disk_cache: CacheMaxFileSize, CacheMinFileSize, CacheReadSize and
440 CacheReadTime can be set per directory/location. [Graham Leggett]
442 *) core: Speed up config parsing if using a very large number of config
443 files. PR 50002 [andrew cloudaccess net]
445 *) mod_cache: Support the caching of HEAD requests. [Graham Leggett]
447 *) htcacheclean: Allow the option to round up file sizes to a given
448 block size, improving the accuracy of disk usage. [Graham Leggett]
450 *) mod_ssl: Add authz providers for use with mod_authz_core and its
451 RequireAny/RequireAll containers: 'ssl' (equivalent to SSLRequireSSL),
452 'ssl-verify-client' (for use with 'SSLVerifyClient optional'), and
453 'ssl-require' (expressions with same syntax as SSLRequire).
456 *) mod_ssl: Make the ssl expression parser thread-safe. It now requires
457 bison instead of yacc. [Stefan Fritsch]
459 *) mod_disk_cache: Change on-disk header file format to support the
460 link of the device/inode of the data file to the matching header
461 file, and to support the option of not writing a data file when
462 the data file is empty. [Graham Leggett]
464 *) core/mod_unique_id: Add generate_log_id hook to allow to use
465 the ID generated by mod_unique_id as error log ID for requests.
468 *) mod_cache: Make sure that we never allow a 304 Not Modified response
469 that we asked for to leak to the client should the 304 response be
470 uncacheable. PR45341 [Graham Leggett]
472 *) mod_cache: Add the cache_status hook to register the final cache
473 decision hit/miss/revalidate. Add optional support for an X-Cache
474 and/or an X-Cache-Detail header to add the cache status to the
475 response. PR48241 [Graham Leggett]
477 *) mod_authz_host: Add 'local' provider that matches connections originating
478 on the local host. PR 19938. [Stefan Fritsch]
480 *) Event MPM: Fix crash accessing pollset on worker thread when child
481 process is exiting. [Jeff Trawick]
483 *) core: For process invocation (cgi, fcgid, piped loggers and so forth)
484 pass the system library path (LD_LIBRARY_PATH or platform-specific
485 variables) along with the system PATH, by default. Both should be
486 overridden together as desired using PassEnv etc; see mod_env.
489 *) mod_cache: Introduce CacheStoreExpired, to allow administrators to
490 capture a stale backend response, perform If-Modified-Since requests
491 against the backend, and serving from the cache all 304 responses.
492 This restores pre-2.2.4 cache behavior. [William Rowe]
494 *) mod_rewrite: Introduce <=, >= string comparison operators, and integer
495 comparators -lt, -le, -eq, -ge, and -gt. To help bash users and drop
496 the ambiguity of the symlink test "-ltest", introduce -h or -L as
497 symlink test operators. [William Rowe]
499 *) mod_cache: Give the cache provider the opportunity to choose to cache
500 or not cache based on the buckets present in the brigade, such as the
501 presence of a FILE bucket.
504 *) mod_authz_core: Allow authz providers to check args while reading the
505 config and allow to cache parsed args. Move 'all' and 'env' authz
506 providers from mod_authz_host to mod_authz_core. Add 'method' authz
507 provider depending on the HTTP method. [Stefan Fritsch]
509 *) mod_include: Move the request_rec within mod_include to be
510 exposed within include_ctx_t. [Graham Leggett]
512 *) mod_include: Reinstate support for UTF-8 character sets by allowing a
513 variable being echoed or set to be decoded and then encoded as separate
514 steps. PR47686 [Graham Leggett]
516 *) mod_cache: Add a discrete commit_entity() provider function within the
517 mod_cache provider interface which is called to indicate to the
518 provider that caching is complete, giving the provider the opportunity
519 to commit temporary files permanently to the cache in an atomic
520 fashion. Replace the inconsistent use of error cleanups with a formal
521 set of pool cleanups attached to a subpool, which is destroyed on error.
524 *) mod_cache: Change the signature of the store_body() provider function
525 within the mod_cache provider interface to support an "in" brigade
526 and an "out" brigade instead of just a single input brigade. This
527 gives a cache provider the option to consume only part of the brigade
528 passed to it, rather than the whole brigade as was required before.
529 This fixes an out of memory and a request timeout condition that would
530 occur when the original document was a large file. Introduce
531 CacheReadSize and CacheReadTime directives to mod_disk_cache to control
532 the amount of data to attempt to cache at a time. [Graham Leggett]
534 *) core: Add ErrorLogFormat to allow configuring error log format, including
535 additional information that is logged once per connection or request. Add
536 error log IDs for connections and request to allow correlating error log
537 lines and the corresponding access log entry. [Stefan Fritsch]
539 *) core: Disable sendfile by default. [Stefan Fritsch]
541 *) mod_cache: Check the request to determine whether we are allowed
542 to return cached content at all, and respect a "Cache-Control:
543 no-cache" header from a client. Previously, "no-cache" would
544 behave like "max-age=0". [Graham Leggett]
546 *) mod_cache: Use a proper filter context to hold filter data instead
547 of misusing the per-request configuration. Fixes a segfault on trunk
548 when the normal handler is used. [Graham Leggett]
550 *) mod_cgid: Log a warning if the ScriptSock path is truncated because
551 it is too long. PR 49388. [Stefan Fritsch]
553 *) vhosts: Do not allow _default_ in NameVirtualHost, or mixing *
554 and non-* ports on NameVirtualHost, or multiple NameVirtualHost
555 directives for the same address:port, or NameVirtualHost
556 directives with no matching VirtualHosts, or multiple ip-based
557 VirtualHost sections for the same address:port. These were
558 previously accepted with a warning, but the behavior was
559 undefined. [Dan Poirier]
561 *) mod_remoteip: Fix a segfault when using mod_remoteip in conjunction with
562 Allow/Deny. PR 49838. [Andrew Skalski <voltara gmail.com>]
564 *) core: DirectoryMatch can now match on the end of line character ($),
565 and sub-directories of matched directories are no longer implicitly
566 matched. PR49809 [Eric Covener]
568 *) Regexps: introduce new higher-level regexp utility including parsing
569 and executing perl-style regexp ops (e.g s/foo/bar/i) and regexp memory
572 *) Proxy: support setting source address. PR 29404

1681 requests, rather being downgraded to GET requests. [Graham Leggett]
1683 *) mod_ssl: Fix TLS upgrade (RFC 2817) support. PR 41231. [Joe Orton]
1685 *) scoreboard: Correctly declare ap_time_process_request.
1686 PR 43789 [Tom Donovan <Tom.Donovan acm.org>]
1688 *) core; scoreboard: ap_get_scoreboard_worker(sbh) now takes the sbh member
1689 from the connection rec, ap_get_scoreboard_worker(proc, thread) will now
1690 provide the unusual legacy lookup. [William Rowe]
1692 *) mpm winnt: fix null pointer dereference
1693 PR 42572 [Davi Arnaut]
1695 *) mod_authnz_ldap, mod_authn_dbd: Tidy up the code to expose authn
1696 parameters to the environment. Improve portability to
1697 EBCDIC machines by using apr_toupper(). [Martin Kraemer]
1699 *) mod_ldap, mod_authnz_ldap: Add support for nested groups (i.e. the ability
1700 to authorize an authenticated user via a "require ldap-group X" directive
1701 where the user is not in group X, but is in a subgroup contained in X.
1702 PR 42891 [Paul J. Reder]
1704 *) mod_ssl: Add support for caching SSL Sessions in memcached. [Paul Querna]
1706 *) apxs: Enhance -q flag to print all known variables and their values
1707 when invoked without variable name(s).
1708 [William Rowe, Sander Temme]
1710 *) apxs: Eliminate run-time check for mod_so. PR 40653.
1711 [David M. Lee <dmlee crossroads.com>]
1713 *) beos MPM: Create pmain pool and run modules' child_init hooks when
1714 entering ap_mpm_run(), then destroy pmain when exiting ap_mpm_run().
1717 *) netware MPM: Destroy pmain pool when exiting ap_mpm_run() so that
1718 cleanups registered in modules' child_init hooks are performed.
1721 *) Fix issue which could cause error messages to be written to access logs
1722 on Win32. PR 40476. [Tom Donovan <Tom.Donovan acm.org>]
1724 *) The LockFile directive, which specifies the location of
1725 the accept() mutex lockfile, is deprecated. Instead, the
1726 AcceptMutex directive now takes an optional lockfile
1727 location parameter, ala SSLMutex. [Jim Jagielski]
1729 *) mod_authn_dbd: Export any additional columns queried in the SQL select
1730 into the environment with the name AUTHENTICATE_<COLUMN>. This brings
1731 mod_authn_dbd behaviour in line with mod_authnz_ldap. [Graham Leggett]
1733 *) mod_dbd: Key the storage of prepared statements on the hex string
1734 value of server_rec, rather than the server name, as the server name
1735 may change (eg when the server name is set) at any time, causing
1736 weird behaviour in modules dependent on mod_dbd. [Graham Leggett]
1738 *) mod_proxy_fcgi: Added win32 build. [Mladen Turk]
1740 *) sendfile_nonblocking() takes the _brigade_ as an argument, gets
1741 the first bucket from the brigade, finds it not to be a FILE
1742 bucket and barfs. The fix is to pass a bucket rather than a brigade.
1743 [Niklas Edmundsson <nikke acc.umu.se>]
1745 *) mod_rewrite: support rewritemap by SQL query [Nick Kew]
1747 *) ap_get_server_version() has been removed. Third-party modules must
1748 now use ap_get_server_banner() or ap_get_server_description().
1751 *) All MPMs: Introduce a check_config phase between pre_config and
1752 open_logs, to allow modules to review interdependent configuration
1753 directive values and adjust them while messages can still be logged
1754 to the console. Handle relevant MPM directives during this phase
1755 and format messages for both the console and the error log, as
1756 appropriate. [Chris Darroch]
1758 *) core: Do not allow internal redirects like the DirectoryIndex of mod_dir
1759 to circumvent the symbolic link checks imposed by FollowSymLinks and
1760 SymLinksIfOwnerMatch. [Nick Kew, Ruediger Pluem, William Rowe]
1762 *) New SSLLogLevelDebugDump [ None (default) | IO (not bytes) | Bytes ]
1763 configures the I/O Dump of SSL traffic, when LogLevel is set to Debug.
1764 The default is none as this is far greater debugging resolution than
1765 the typical administrator is prepared to untangle. [William Rowe]
1767 *) mod_disk_cache: If possible, check if the size of an object to cache is
1768 within the configured boundaries before actually saving data.

1791 *) mod_charset_lite: Remove Content-Length when output filter can
1792 invalidate it. Warn when input filter can invalidate it.
1795 *) Authz: Add the new module mod_authn_core that will provide common
1796 authn directives such as 'AuthType', 'AuthName'. Move the directives
1797 'AuthType' and 'AuthName' out of the core module and merge mod_authz_alias
1798 into mod_authn_core. [Brad Nicholes]
1800 *) Authz: Move the directives 'Order', 'Allow', 'Deny' and 'Satisfy'
1801 into the new module mod_access_compat which can be loaded to provide
1802 support for these directives.
1805 *) Authz: Move the 'Require' directive from the core module as well as
1806 add the directives '<SatisfyAll>', '<SatisfyOne>', '<RequireAlias>'
1807 and 'Reject' to mod_authz_core. The new directives introduce 'AND/OR'
1808 logic into the authorization processing. [Brad Nicholes]
1810 *) Authz: Add the new module mod_authz_core which acts as the
1811 authorization provider vector and contains common authz
1812 directives. [Brad Nicholes]
1814 *) Authz: Renamed mod_authz_dbm authz providers from 'group' and
1815 'file-group' to 'dbm-group' and 'dbm-file-group'. [Brad Nicholes]
1817 *) Authz: Added the new authz providers 'env', 'ip', 'host', 'all' to handle
1818 host-based access control provided by mod_authz_host and invoked
1819 through the 'Require' directive. [Brad Nicholes]
1821 *) Authz: Convert all of the authz modules from hook based to
1822 provider based. [Brad Nicholes]
1824 *) mod_cache: Add CacheMinExpire directive to set the minimum time in
1825 seconds to cache a document.
1826 [Brian Akins <brian.akins turner.com>, Ruediger Pluem]
1828 *) mod_authz_dbd: SQL authz with Login/Session support [Nick Kew]
1830 *) Fix typo in ProxyStatus syntax error message.
1831 [Christophe Jaillet <christophe.jaillet wanadoo.fr>]
1833 *) Asynchronous write completion for the Event MPM. [Brian Pane]
1835 *) Added an End-Of-Request bucket type. The logging of a request and
1836 the freeing of its pool are now done when the EOR bucket is destroyed.
1837 This has the effect of delaying the logging until right after the last
1838 of the response is sent; ap_core_output_filter() calls the access logger
1839 indirectly when it destroys the EOR bucket. [Brian Pane]
1841 *) Rewrite of logresolve support utility: IPv6 addresses are now supported
1842 and the format of statistical output has changed. [Colm MacCarthaigh]
1844 *) Rewrite of ap_coreoutput_filter to do nonblocking writes [Brian Pane]
1846 *) Added new connection states for handler and write completion
1849 *) mod_cgid: Refuse to work on Solaris 10 due to OS bugs. PR 34264.
1852 *) Teach mod_ssl to use arbitrary OIDs in an SSLRequire directive,
1853 allowing string-valued client certificate attributes to be used for
1854 access control, as in: SSLRequire "value" in OID("1.3.6.1.4.1.18060.1")
