2 Changes with Apache 2.3.0
3 [ When backported to 2.2.x, remove entry from this file ]
5 *) Move the KeptBodySize directive, kept_body filters and the
6 ap_parse_request_body function out of the http module and into a
7 new module called mod_request, reducing the size of the core.
10 *) rotatelogs: Log the current file size and error code/description
11 when failing to write to the log file. [Jeff Trawick]
13 *) mod_dbd: Handle integer configuration directive parameters with a
16 *) Change the directives within the mod_session* modules to be valid
17 both inside and outside the location/directory sections, as
18 suggested by wrowe. [Graham Leggett]
20 *) mod_auth_form: Add a module capable of allowing end users to log
21 in using an HTML form, storing the credentials within mod_session.
24 *) Add a function to the http filters that is able to parse an HTML
25 form request with the type of application/x-www-form-urlencoded.
28 *) mod_session_crypto: Initialise SSL in the post config hook.
29 [Ruediger Pluem, Graham Leggett]
31 *) mod_session_dbd: Add a session implementation capable of storing
32 session information in a SQL database via the dbd interface. Useful
33 for sites where session privacy is important. [Graham Leggett]
35 *) mod_session_crypto: Add a session encoding implementation capable
36 of encrypting and decrypting sessions wherever they may be stored.
37 Introduces a level of privacy when sessions are stored on the
38 browser. [Graham Leggett]
40 *) mod_session_cookie: Add a session implementation capable of storing
41 session information within cookies on the browser. Useful for high
42 volume sites where server bound sessions are too resource intensive.
45 *) mod_session: Add a generic session interface to unify the different
46 attempts at saving persistent sessions across requests.
49 *) core, authn/z: Avoid calling access control hooks for internal requests
50 with configurations which match those of initial request. Revert to
51 original behaviour (call access control hooks for internal requests
52 with URIs different from initial request) if any access control hooks or
53 providers are not registered as permitting this optimization.
54 Introduce wrappers for access control hook and provider registration
55 which can accept additional mode and flag data. [Chris Darroch]
57 *) http_filters: Don't spin if get an error when reading the
58 next chunk. PR 44381 [Ruediger Pluem]
60 *) mod_dav: Return "method not allowed" if the destination URI of a WebDAV
61 copy / move operation is no DAV resource. PR 44734 [Ruediger Pluem]
63 *) Introduced ap_expr API for expression evaluation.
64 This is adapted from mod_include, which is the first module
68 *) mod_authz_dbd: When redirecting after successful login/logout per
69 AuthzDBDRedirectQuery, do not report authorization failure, and use
70 first row returned by database query instead of last row.
73 *) mod_rewrite: Initialize hash needed by ap_register_rewrite_mapfunc early
74 enough. PR 44641 [Daniel Lescohier <daniel.lescohier cnet.com>]
76 *) mod_authn_dbd: Disambiguate and tidy database authentication
77 error messages. PR 43210. [Chris Darroch, Phil Endecott
78 <spam_from_apache_bugzilla chezphil.org>]
80 *) mod_cache: Handle If-Range correctly if the cached resource was stale.
81 PR 44579 [Ruediger Pluem]
83 *) mod_speling: remove regression from 1.3/2.0 behavior and
84 drop dependency between mod_speling and AcceptPathInfo.
85 PR 43562 [Jose Kahan <jose w3.org>]
87 *) mod_ldap: Correctly return all requested attribute values
88 when some attributes have a null value.
89 PR 44560 [Anders Kaseorg <anders kaseorg.com>]
91 *) core: check symlink ownership if both FollowSymlinks and
92 SymlinksIfOwnerMatch are set [Nick Kew]
94 *) core: fix origin checking in SymlinksIfOwnerMatch
95 PR 36783 [Robert L Mathews <rob-apache.org.bugs tigertech.net>]
97 *) rotatelogs: Added '-f' option to force rotatelogs to create the
98 logfile as soon as started, and not wait until it reads the
99 first entry. [Jim Jagielski]
101 *) mod_proxy: Do not try a direct connection if the connection via a
102 remote proxy failed before and the request has a request body.
105 *) mod_substitute: The default is now flattening the buckets after
106 each substitution. This was mostly done to abide by the
107 Principle Of Least Astonishment. The newly added 'q' flag allows for
108 the quicker, more efficient bucket-splitting if the user so
109 desires. [Jim Jagielski]
111 *) Added 'disablereuse' option for ProxyPass which, essentially,
112 disables connection pooling for the backend servers.
115 *) Activate mod_cache, mod_file_cache and mod_disc_cache as part of the
116 'most' set for '--enable-modules' and '--enable-shared-mods'. Include
117 mod_mem_cache in 'all' as well. [Dirk-Willem van Gulik]
119 *) Also install mod_so.h, mod_rewrite.h and mod_cache.h; as these
120 contain public function declarations which are useful for
121 third party module authors. PR 42431 [Dirk-Willem van Gulik].
123 *) mod_dir, mod_negotiation: pass the output filter information
124 to newly created sub requests; as these are later on used
125 as true requests with an internal redirect. This allows for
126 mod_cache et.al. to trap the results of the redirect.
127 [Dirk-Willem van Gulik, Ruediger Pluem]
129 *) ab: Use a 64 bit unsigned int instead of a signed long to count the
130 bytes transferred to avoid integer overflows. PR 44346 [Ruediger Pluem]
132 *) mod_proxy_ajp: Do not retry request in the case that we either failed to
133 sent a part of the request body or if the request is not idempotent.
134 PR 44334 [Ruediger Pluem]
136 *) rotatelogs: Don't leak memory when reopening the logfile.
137 PR 40183 [Ruediger Pluem, Takashi Sato <serai lans-tv.com>]
139 *) mod_ldap: Add support (taking advantage of the new APR capability)
140 for ldap rebind callback while chasing referrals. This allows direct
141 searches on LDAP servers (in particular MS Active Directory 2003+)
142 using referrals without the use of the global catalog.
143 PRs 26538, 40268, and 42557 [Paul J. Reder]
145 *) ab: Do not try to read non existing response bodies of HEAD requests.
146 PR 34275 [Takashi Sato <serai lans-tv.com>]
148 *) Support chroot on Unix-family platforms
149 PR 43596 [Dimitar Pashev <mitko banksoft-bg.com>]
151 *) mod_proxy_http: Return HTTP status codes instead of apr_status_t
152 values for errors encountered while forwarding the request body
153 PR 44165 [Eric Covener]
155 *) mod_ssl: Added server name indication support (SNI, RFC 4366).
156 PR 34607. [Kaspar Brand <asfbugz velox.ch>]. A test configuration
157 can be created with test/make_sni.sh [Dirk-Willem van Gulik].
159 *) ApacheMonitor.exe: Introduce --kill argument for use by the
160 installer. This will permit the installation tool to remove
161 all running instances before attempting to remove the .exe.
164 *) mod_proxy: Lower memory consumption for short lived connections.
165 PR 44026. [Ruediger Pluem]
167 *) mod_proxy: Keep connections to the backend persistent in the HTTPS case.
170 *) rotatelogs: Improve atomicity when using -l and cleaup code.
171 PR 44004 [Rainer Jung]
173 *) mod_ssl: Add support for OCSP validation of client certificates.
174 PR 41123. [Marc Stern <marc.stern approach.be>, Joe Orton]
176 *) mod_unique_id: Fix timestamp value in UNIQUE_ID.
177 PR 37064 [Kobayashi <kobayashi firstserver.co.jp>]
179 *) mod_serf: New module for Reverse Proxying. [Paul Querna]
181 *) core: Add the option to keep aside a request body up to a certain
182 size that would otherwise be discarded, to be consumed by filters
183 such as mod_include. When enabled for a directory, POST requests
184 to shtml files can be passed through to embedded scripts as POST
185 requests, rather being downgraded to GET requests. [Graham Leggett]
187 *) mod_ssl: Fix TLS upgrade (RFC 2817) support. PR 41231. [Joe Orton]
189 *) scoreboard: Correctly declare ap_time_process_request.
190 PR 43789 [Tom Donovan <Tom.Donovan acm.org>]
192 *) core; scoreboard: ap_get_scoreboard_worker(sbh) now takes the sbh member
193 from the connection rec, ap_get_scoreboard_worker(proc, thread) will now
194 provide the unusual legacy lookup. [William Rowe]
196 *) mpm winnt: fix null pointer dereference
197 PR 42572 [Davi Arnaut]
199 *) core: reinstate location walk to fix config for subrequests
200 PR 41960 [Jose Kahan <jose w3.org>]
202 *) mod_log_config: Add format options for %p so that the actual local
203 or remote port can be logged. PR 43415. [Adam Hasselbalch Hansen
204 <ahh@one.com>, Ruediger Pluem, Jeff Trawick]
206 *) mod_authnz_ldap, mod_authn_dbd: Tidy up the code to expose authn
207 parameters to the environment. Improve portability to
208 EBCDIC machines by using apr_toupper(). [Martin Kraemer]
210 *) mod_ldap, mod_authnzldap: Add support for nested groups (i.e. the ability
211 to authorize an authenticated user via a "require ldap-group X" directive
212 where the user is not in group X, but is in a subgroup contained in X.
213 PR 42891 [Paul J. Reder]
215 *) mod_ssl: Add support for caching SSL Sessions in memcached. [Paul Querna]
217 *) ab: Add -r option to continue after socket receive errors.
218 [Filip Hanik <devlist hanik.com>]
220 *) mod_ldap: Fix the search limit parameter to ldap_search_ext_s()
221 for SDKs that define LDAP_NO_LIMIT to something other than -1.
222 [David Jones <oscaremma gmail.com>]
224 *) apxs: Enhance -q flag to print all known variables and their values
225 when invoked without variable name(s).
226 [William Rowe, Sander Temme]
228 *) apxs: Eliminate run-time check for mod_so. PR 40653.
229 [David M. Lee <dmlee crossroads.com>]
231 *) beos MPM: Create pmain pool and run modules' child_init hooks when
232 entering ap_mpm_run(), then destroy pmain when exiting ap_mpm_run().
235 *) netware MPM: Destroy pmain pool when exiting ap_mpm_run() so that
236 cleanups registered in modules' child_init hooks are performed.
239 *) mod_dbd: Stash DBD connections in request_config of initial request
240 only, or else sub-requests and internal redirections may cause
241 entire DBD pool to be stashed in a single HTTP request. [Chris Darroch]
243 *) Fix issue which could cause error messages to be written to access logs
244 on Win32. PR 40476. [Tom Donovan <Tom.Donovan acm.org>]
246 *) The LockFile directive, which specifies the location of
247 the accept() mutex lockfile, is deprecated. Instead, the
248 AcceptMutex directive now takes an optional lockfile
249 location parameter, ala SSLMutex. [Jim Jagielski]
251 *) mod_authn_dbd: Export any additional columns queried in the SQL select
252 into the environment with the name AUTHENTICATE_<COLUMN>. This brings
253 mod_authn_dbd behaviour in line with mod_authnz_ldap. [Graham Leggett]
255 *) mod_dbd: Key the storage of prepared statements on the hex string
256 value of server_rec, rather than the server name, as the server name
257 may change (eg when the server name is set) at any time, causing
258 weird behaviour in modules dependent on mod_dbd. [Graham Leggett]
260 *) mod_proxy_fcgi: Added win32 build. [Mladen Turk]
262 *) sendfile_nonblocking() takes the _brigade_ as an argument, gets
263 the first bucket from the brigade, finds it not to be a FILE
264 bucket and barfs. The fix is to pass a bucket rather than a brigade.
265 [Niklas Edmundsson <nikke acc.umu.se>]
267 *) mod_rewrite: support rewritemap by SQL query [Nick Kew]
269 *) ap_get_server_version() has been removed. Third-party modules must
270 now use ap_get_server_banner() or ap_get_server_description().
273 *) All MPMs: Introduce a check_config phase between pre_config and
274 open_logs, to allow modules to review interdependent configuration
275 directive values and adjust them while messages can still be logged
276 to the console. Handle relevant MPM directives during this phase
277 and format messages for both the console and the error log, as
278 appropriate. [Chris Darroch]
280 *) mod_proxy: don't URLencode tilde in path component
281 [Stijn Hoop <stijn sandcat.nl>]
283 *) mpm_winnt: Fix return values from wait_for_many_objects.
284 The return value is index to the signaled thread in the
285 creted_threads array. We can not use WAIT_TIMEOUT because
286 his value is defined as 258, thus limiting the MaxThreads
287 to that value. [Mladen Turk]
289 *) core: Do not allow internal redirects like the DirectoryIndex of mod_dir
290 to circumvent the symbolic link checks imposed by FollowSymLinks and
291 SymLinksIfOwnerMatch. [Nick Kew, Ruediger Pluem, William Rowe]
293 *) mod_proxy: Support environment variable interpolation in reverse
294 proxying directives. [Nick Kew]
296 *) core: Add the filename of the configuration file to the warning message
297 about the useless use of AllowOverride. PR 39992.
298 [Darryl Miles <darryl darrylmiles.org>]
300 *) New SSLLogLevelDebugDump [ None (default) | IO (not bytes) | Bytes ]
301 configures the I/O Dump of SSL traffic, when LogLevel is set to Debug.
302 The default is none as this is far greater debugging resolution than
303 the typical administrator is prepared to untangle. [William Rowe]
305 *) mod_disk_cache: If possible, check if the size of an object to cache is
306 within the configured boundaries before actually saving data.
307 [Niklas Edmundsson <nikke acc.umu.se>]
309 *) mod_cache: Convert all values to seconds before comparing them when
310 checking whether to send a Warning header for a stale response.
311 PR 39713. [Owen Taylor <otaylor redhat.com>]
313 *) mod_disk_cache: Delete temporary files if they cannot be renamed to their
314 final name. [Davi Arnaut <davi haxent.com.br>]
316 *) Worker and event MPMs: Remove improper scoreboard updates which were
317 performed in the event of a fork() failure. [Chris Darroch]
319 *) Add support for fcgi:// proxies to mod_rewrite.
320 [Markus Schiegl <ms schiegl.com>]
322 *) Remove incorrect comments from scoreboard.h regarding conditional
323 loading of worker_score structure with mod_status, and remove unused
324 definitions relating to old life_status field.
325 [Chris Darroch <chrisd pearsoncmg.com>]
327 *) Remove allocation of memory for unused array of lb_score pointers
328 in ap_init_scoreboard(). [Chris Darroch <chrisd pearsoncmg.com>]
330 *) Add mod_proxy_fcgi, a FastCGI back end for mod_proxy.
331 [Garrett Rooney, Jim Jagielski, Paul Querna]
333 *) Event MPM: Fill in the scoreboard's tid field. PR 38736.
334 [Chris Darroch <chrisd pearsoncmg.com>]
336 *) mod_charset_lite: Remove Content-Length when output filter can
337 invalidate it. Warn when input filter can invalidate it.
340 *) Authz: Add the new module mod_authn_core that will provide common
341 authn directives such as 'AuthType', 'AuthName'. Move the directives
342 'AuthType' and 'AuthName' out of the core module and merge mod_authz_alias
343 into mod_authn_core. [Brad Nicholes]
345 *) Authz: Move the directives 'Order', 'Allow', 'Deny' and 'Satisfy'
346 into the new module mod_access_compat which can be loaded to provide
347 support for these directives.
350 *) Authz: Move the 'Require' directive from the core module as well as
351 add the directives '<SatisfyAll>', '<SatisfyOne>', '<RequireAlias>'
352 and 'Reject' to mod_authz_core. The new directives introduce 'AND/OR'
353 logic into the authorization processing. [Brad Nicholes]
355 *) Authz: Add the new module mod_authz_core which acts as the
356 authorization provider vector and contains common authz
357 directives. [Brad Nicholes]
359 *) Authz: Renamed mod_authz_dbm authz providers from 'group' and
360 'file-group' to 'dbm-group' and 'dbm-file-group'. [Brad Nicholes]
362 *) Authz: Added the new authz providers 'env', 'ip', 'host', 'all' to handle
363 host-based access control provided by mod_authz_host and invoked
364 through the 'Require' directive. [Brad Nicholes]
366 *) Authz: Convert all of the authz modules from hook based to
367 provider based. [Brad Nicholes]
369 *) mod_cache: Add CacheMinExpire directive to set the minimum time in
370 seconds to cache a document.
371 [Brian Akins <brian.akins turner.com>, Ruediger Pluem]
373 *) mod_authz_dbd: SQL authz with Login/Session support [Nick Kew]
375 *) Fix typo in ProxyStatus syntax error message.
376 [Christophe Jaillet <christophe.jaillet wanadoo.fr>]
378 *) Asynchronous write completion for the Event MPM. [Brian Pane]
380 *) Added an End-Of-Request bucket type. The logging of a request and
381 the freeing of its pool are now done when the EOR bucket is destroyed.
382 This has the effect of delaying the logging until right after the last
383 of the response is sent; ap_core_output_filter() calls the access logger
384 indirectly when it destroys the EOR bucket. [Brian Pane]
386 *) Rewrite of logresolve support utility: IPv6 addresses are now supported
387 and the format of statistical output has changed. [Colm MacCarthaigh]
389 *) Rewrite of ap_coreoutput_filter to do nonblocking writes [Brian Pane]
391 *) Added new connection states for handler and write completion
394 *) mod_cgid: Refuse to work on Solaris 10 due to OS bugs. PR 34264.
397 *) Teach mod_ssl to use arbitrary OIDs in an SSLRequire directive,
398 allowing string-valued client certificate attributes to be used for
399 access control, as in: SSLRequire "value" in OID("1.3.6.1.4.1.18060.1")
