3 [ When backported to 2.2.x, remove entry from this file ]
5 *) mod_proxy_ajp: Fix wrongly formatted requests where client
6 sets Content-Length header, but doesn't provide a body.
7 Servlet container always expects that next packet is
8 body whenever C-L is present in the headers. This can lead
9 to wrong interpretation of the packets. In this case
10 send the empty body packet, so container can deal with
13 *) mod_authnz_ldap: don't return NULL-valued environment variables to
14 other modules. PR 39045 [Francois Pesce <francois.pesce gmail.com>]
16 *) Don't adjust case in pathname components that are not of interest
17 to mod_mime. Fixes mod_negotiation's use of such components.
18 PR 43250 [Basant Kumar Kukreja <basant.kukreja sun.com>]
20 *) Add new LogFormat parameter, %k, which logs the number of
21 keepalive requests on this connection for this request..
22 [Dan Poirier <poirier pobox.com>]
24 *) Be tolerant in what you accept - accept slightly broken
25 status lines from a backend provide they include a valid status code.
26 PR 44995 [Rainer Jung <rainer.jung kippdata.de>]
28 *) New module mod_sed: filter Request/Response bodies through sed
29 [Basant Kumar Kukreja <basant.kukreja sun.com>]
31 *) mod_auth_form: Make sure that basic authentication is correctly
32 faked directly after login. [Graham Leggett]
34 *) mod_session_cookie, mod_session_dbd: Make sure cookies are set both
35 within the output headers and error output headers, so that the
36 session is maintained across redirects. [Graham Leggett]
38 *) mod_auth_form: Make sure the logged in user is populated correctly
39 after a form login. Fixes a missing REMOTE_USER variable directly
40 following a login. [Graham Leggett]
42 *) mod_session_cookie: Make sure that cookie attributes are correctly
43 included in the blank cookie when cookies are removed. This fixes an
44 inability to log out when using mod_auth_form. [Graham Leggett]
46 *) mod_autoindex: add configuration option to insert string
47 in HTML HEAD. [Nick Kew]
49 *) mod_ssl: implement dynamic mutex callbacks for the benefit of
50 OpenSSL. [Sander Temme]
52 *) mod_session: Prevent a segfault when a CGI script sets a cookie with a
53 null value. [David Shane Holden <dpejesh apache.org>]
55 *) mod_headers: Prevent Header edit from processing only the first header
56 of possibly multiple headers with the same name and deleting the
57 remaining ones. PR 45333. [Ruediger Pluem]
59 *) mod_rewrite: Preserve the query string with [proxy,noescape]. PR 45247
62 *) core, authn/z: Determine registered authn/z providers directly in
63 ap_setup_auth_internal(), which allows optional functions that just
64 wrapped ap_list_provider_names() to be removed from authn/z modules.
67 *) authn/z: Convert common provider version strings to macros.
70 *) ab: Make ab.c compile on VC6. PR 45024 [Ruediger Pluem]
72 *) configure: Don't reject libtool 2.x
73 PR 44817 [Arfrever Frehtes Taifersar Arahesis <Arfrever.FTA gmail.com>]
75 *) core: When testing for slash-terminated configuration paths in
76 ap_location_walk(), don't look past the start of an empty string
77 such as that created by a <Location ""> directive.
80 *) core, mod_proxy: If a kept_body is present, it becomes safe for
81 subrequests to support message bodies. Make sure that safety
82 checks within the core and within the proxy are not triggered
83 when kept_body is present. This makes it possible to embed
84 proxied POST requests within mod_include. [Graham Leggett]
86 *) mod_auth_form: Make sure the input filter stack is properly set
87 up before reading the login form. Make sure the kept body filter
88 is correctly inserted to ensure the body can be read a second
89 time safely should the authn be successful. [Graham Leggett,
92 *) mod_request: Insert the KEPT_BODY filter via the insert_filter
93 hook instead of during fixups. Add a safety check to ensure the
94 filters cannot be inserted more than once. [Graham Leggett,
97 *) core: Do not allow Options ALL if not all options are allowed to be
98 overwritten. PR 44262 [Michał Grzędzicki <lazy iq.pl>]
100 *) ap_cache_cacheable_headers_out() will (now) always
101 merge an error heaeders _before_ clearing them and _before_
102 merging in the actual entity headers and doing normal
103 hop-by-hop cleansing. [Dirk-Willem van Gulik].
105 *) cache: retire ap_cache_cacheable_hdrs_out() which was used
106 for both in- and out-put headers; and replace it by a single
107 ap_cache_cacheable_headers() wrapped in a in- and out-put
108 specific ap_cache_cacheable_headers_in()/out(). The latter
109 which will also merge error and ensure content-type. To keep
110 cache modules consistent with ease. This API change bumps
111 up the minor MM by one [Dirk-Willem van Gulik].
113 *) mod_rewrite: Allow Cookie option to set secure and HttpOnly flags.
114 PR 44799 [Christian Wenz <christian wenz.org>]
116 *) Move the KeptBodySize directive, kept_body filters and the
117 ap_parse_request_body function out of the http module and into a
118 new module called mod_request, reducing the size of the core.
121 *) mod_dbd: Handle integer configuration directive parameters with a
124 *) Change the directives within the mod_session* modules to be valid
125 both inside and outside the location/directory sections, as
126 suggested by wrowe. [Graham Leggett]
128 *) mod_auth_form: Add a module capable of allowing end users to log
129 in using an HTML form, storing the credentials within mod_session.
132 *) Add a function to the http filters that is able to parse an HTML
133 form request with the type of application/x-www-form-urlencoded.
136 *) mod_session_crypto: Initialise SSL in the post config hook.
137 [Ruediger Pluem, Graham Leggett]
139 *) mod_session_dbd: Add a session implementation capable of storing
140 session information in a SQL database via the dbd interface. Useful
141 for sites where session privacy is important. [Graham Leggett]
143 *) mod_session_crypto: Add a session encoding implementation capable
144 of encrypting and decrypting sessions wherever they may be stored.
145 Introduces a level of privacy when sessions are stored on the
146 browser. [Graham Leggett]
148 *) mod_session_cookie: Add a session implementation capable of storing
149 session information within cookies on the browser. Useful for high
150 volume sites where server bound sessions are too resource intensive.
153 *) mod_session: Add a generic session interface to unify the different
154 attempts at saving persistent sessions across requests.
157 *) core, authn/z: Avoid calling access control hooks for internal requests
158 with configurations which match those of initial request. Revert to
159 original behaviour (call access control hooks for internal requests
160 with URIs different from initial request) if any access control hooks or
161 providers are not registered as permitting this optimization.
162 Introduce wrappers for access control hook and provider registration
163 which can accept additional mode and flag data. [Chris Darroch]
165 *) Introduced ap_expr API for expression evaluation.
166 This is adapted from mod_include, which is the first module
170 *) mod_authz_dbd: When redirecting after successful login/logout per
171 AuthzDBDRedirectQuery, do not report authorization failure, and use
172 first row returned by database query instead of last row.
175 *) mod_ldap: Correctly return all requested attribute values
176 when some attributes have a null value.
177 PR 44560 [Anders Kaseorg <anders kaseorg.com>]
179 *) core: check symlink ownership if both FollowSymlinks and
180 SymlinksIfOwnerMatch are set [Nick Kew]
182 *) core: fix origin checking in SymlinksIfOwnerMatch
183 PR 36783 [Robert L Mathews <rob-apache.org.bugs tigertech.net>]
185 *) Activate mod_cache, mod_file_cache and mod_disc_cache as part of the
186 'most' set for '--enable-modules' and '--enable-shared-mods'. Include
187 mod_mem_cache in 'all' as well. [Dirk-Willem van Gulik]
189 *) Also install mod_so.h, mod_rewrite.h and mod_cache.h; as these
190 contain public function declarations which are useful for
191 third party module authors. PR 42431 [Dirk-Willem van Gulik].
193 *) mod_dir, mod_negotiation: pass the output filter information
194 to newly created sub requests; as these are later on used
195 as true requests with an internal redirect. This allows for
196 mod_cache et.al. to trap the results of the redirect.
197 [Dirk-Willem van Gulik, Ruediger Pluem]
199 *) mod_ldap: Add support (taking advantage of the new APR capability)
200 for ldap rebind callback while chasing referrals. This allows direct
201 searches on LDAP servers (in particular MS Active Directory 2003+)
202 using referrals without the use of the global catalog.
203 PRs 26538, 40268, and 42557 [Paul J. Reder]
205 *) mod_ssl: Added server name indication support (SNI, RFC 4366).
206 PR 34607. [Kaspar Brand <asfbugz velox.ch>]. A test configuration
207 can be created with test/make_sni.sh [Dirk-Willem van Gulik].
209 *) ApacheMonitor.exe: Introduce --kill argument for use by the
210 installer. This will permit the installation tool to remove
211 all running instances before attempting to remove the .exe.
214 *) mod_ssl: Add support for OCSP validation of client certificates.
215 PR 41123. [Marc Stern <marc.stern approach.be>, Joe Orton]
217 *) mod_serf: New module for Reverse Proxying. [Paul Querna]
219 *) core: Add the option to keep aside a request body up to a certain
220 size that would otherwise be discarded, to be consumed by filters
221 such as mod_include. When enabled for a directory, POST requests
222 to shtml files can be passed through to embedded scripts as POST
223 requests, rather being downgraded to GET requests. [Graham Leggett]
225 *) mod_ssl: Fix TLS upgrade (RFC 2817) support. PR 41231. [Joe Orton]
227 *) scoreboard: Correctly declare ap_time_process_request.
228 PR 43789 [Tom Donovan <Tom.Donovan acm.org>]
230 *) core; scoreboard: ap_get_scoreboard_worker(sbh) now takes the sbh member
231 from the connection rec, ap_get_scoreboard_worker(proc, thread) will now
232 provide the unusual legacy lookup. [William Rowe]
234 *) mpm winnt: fix null pointer dereference
235 PR 42572 [Davi Arnaut]
237 *) mod_authnz_ldap, mod_authn_dbd: Tidy up the code to expose authn
238 parameters to the environment. Improve portability to
239 EBCDIC machines by using apr_toupper(). [Martin Kraemer]
241 *) mod_ldap, mod_authnzldap: Add support for nested groups (i.e. the ability
242 to authorize an authenticated user via a "require ldap-group X" directive
243 where the user is not in group X, but is in a subgroup contained in X.
244 PR 42891 [Paul J. Reder]
246 *) mod_ssl: Add support for caching SSL Sessions in memcached. [Paul Querna]
248 *) mod_ldap: Fix the search limit parameter to ldap_search_ext_s()
249 for SDKs that define LDAP_NO_LIMIT to something other than -1.
250 [David Jones <oscaremma gmail.com>]
252 *) apxs: Enhance -q flag to print all known variables and their values
253 when invoked without variable name(s).
254 [William Rowe, Sander Temme]
256 *) apxs: Eliminate run-time check for mod_so. PR 40653.
257 [David M. Lee <dmlee crossroads.com>]
259 *) beos MPM: Create pmain pool and run modules' child_init hooks when
260 entering ap_mpm_run(), then destroy pmain when exiting ap_mpm_run().
263 *) netware MPM: Destroy pmain pool when exiting ap_mpm_run() so that
264 cleanups registered in modules' child_init hooks are performed.
267 *) mod_dbd: Stash DBD connections in request_config of initial request
268 only, or else sub-requests and internal redirections may cause
269 entire DBD pool to be stashed in a single HTTP request. [Chris Darroch]
271 *) Fix issue which could cause error messages to be written to access logs
272 on Win32. PR 40476. [Tom Donovan <Tom.Donovan acm.org>]
274 *) The LockFile directive, which specifies the location of
275 the accept() mutex lockfile, is deprecated. Instead, the
276 AcceptMutex directive now takes an optional lockfile
277 location parameter, ala SSLMutex. [Jim Jagielski]
279 *) mod_authn_dbd: Export any additional columns queried in the SQL select
280 into the environment with the name AUTHENTICATE_<COLUMN>. This brings
281 mod_authn_dbd behaviour in line with mod_authnz_ldap. [Graham Leggett]
283 *) mod_dbd: Key the storage of prepared statements on the hex string
284 value of server_rec, rather than the server name, as the server name
285 may change (eg when the server name is set) at any time, causing
286 weird behaviour in modules dependent on mod_dbd. [Graham Leggett]
288 *) mod_proxy_fcgi: Added win32 build. [Mladen Turk]
290 *) sendfile_nonblocking() takes the _brigade_ as an argument, gets
291 the first bucket from the brigade, finds it not to be a FILE
292 bucket and barfs. The fix is to pass a bucket rather than a brigade.
293 [Niklas Edmundsson <nikke acc.umu.se>]
295 *) mod_rewrite: support rewritemap by SQL query [Nick Kew]
297 *) ap_get_server_version() has been removed. Third-party modules must
298 now use ap_get_server_banner() or ap_get_server_description().
301 *) All MPMs: Introduce a check_config phase between pre_config and
302 open_logs, to allow modules to review interdependent configuration
303 directive values and adjust them while messages can still be logged
304 to the console. Handle relevant MPM directives during this phase
305 and format messages for both the console and the error log, as
306 appropriate. [Chris Darroch]
308 *) mod_proxy: don't URLencode tilde in path component
309 [Stijn Hoop <stijn sandcat.nl>]
311 *) mpm_winnt: Fix return values from wait_for_many_objects.
312 The return value is index to the signaled thread in the
313 creted_threads array. We can not use WAIT_TIMEOUT because
314 his value is defined as 258, thus limiting the MaxThreads
315 to that value. [Mladen Turk]
317 *) core: Do not allow internal redirects like the DirectoryIndex of mod_dir
318 to circumvent the symbolic link checks imposed by FollowSymLinks and
319 SymLinksIfOwnerMatch. [Nick Kew, Ruediger Pluem, William Rowe]
321 *) New SSLLogLevelDebugDump [ None (default) | IO (not bytes) | Bytes ]
322 configures the I/O Dump of SSL traffic, when LogLevel is set to Debug.
323 The default is none as this is far greater debugging resolution than
324 the typical administrator is prepared to untangle. [William Rowe]
326 *) mod_disk_cache: If possible, check if the size of an object to cache is
327 within the configured boundaries before actually saving data.
328 [Niklas Edmundsson <nikke acc.umu.se>]
330 *) mod_cache: Convert all values to seconds before comparing them when
331 checking whether to send a Warning header for a stale response.
332 PR 39713. [Owen Taylor <otaylor redhat.com>]
334 *) mod_disk_cache: Delete temporary files if they cannot be renamed to their
335 final name. [Davi Arnaut <davi haxent.com.br>]
337 *) Worker and event MPMs: Remove improper scoreboard updates which were
338 performed in the event of a fork() failure. [Chris Darroch]
340 *) Add support for fcgi:// proxies to mod_rewrite.
341 [Markus Schiegl <ms schiegl.com>]
343 *) Remove incorrect comments from scoreboard.h regarding conditional
344 loading of worker_score structure with mod_status, and remove unused
345 definitions relating to old life_status field.
346 [Chris Darroch <chrisd pearsoncmg.com>]
348 *) Remove allocation of memory for unused array of lb_score pointers
349 in ap_init_scoreboard(). [Chris Darroch <chrisd pearsoncmg.com>]
351 *) Add mod_proxy_fcgi, a FastCGI back end for mod_proxy.
352 [Garrett Rooney, Jim Jagielski, Paul Querna]
354 *) Event MPM: Fill in the scoreboard's tid field. PR 38736.
355 [Chris Darroch <chrisd pearsoncmg.com>]
357 *) mod_charset_lite: Remove Content-Length when output filter can
358 invalidate it. Warn when input filter can invalidate it.
361 *) Authz: Add the new module mod_authn_core that will provide common
362 authn directives such as 'AuthType', 'AuthName'. Move the directives
363 'AuthType' and 'AuthName' out of the core module and merge mod_authz_alias
364 into mod_authn_core. [Brad Nicholes]
366 *) Authz: Move the directives 'Order', 'Allow', 'Deny' and 'Satisfy'
367 into the new module mod_access_compat which can be loaded to provide
368 support for these directives.
371 *) Authz: Move the 'Require' directive from the core module as well as
372 add the directives '<SatisfyAll>', '<SatisfyOne>', '<RequireAlias>'
373 and 'Reject' to mod_authz_core. The new directives introduce 'AND/OR'
374 logic into the authorization processing. [Brad Nicholes]
376 *) Authz: Add the new module mod_authz_core which acts as the
377 authorization provider vector and contains common authz
378 directives. [Brad Nicholes]
380 *) Authz: Renamed mod_authz_dbm authz providers from 'group' and
381 'file-group' to 'dbm-group' and 'dbm-file-group'. [Brad Nicholes]
383 *) Authz: Added the new authz providers 'env', 'ip', 'host', 'all' to handle
384 host-based access control provided by mod_authz_host and invoked
385 through the 'Require' directive. [Brad Nicholes]
387 *) Authz: Convert all of the authz modules from hook based to
388 provider based. [Brad Nicholes]
390 *) mod_cache: Add CacheMinExpire directive to set the minimum time in
391 seconds to cache a document.
392 [Brian Akins <brian.akins turner.com>, Ruediger Pluem]
394 *) mod_authz_dbd: SQL authz with Login/Session support [Nick Kew]
396 *) Fix typo in ProxyStatus syntax error message.
397 [Christophe Jaillet <christophe.jaillet wanadoo.fr>]
399 *) Asynchronous write completion for the Event MPM. [Brian Pane]
401 *) Added an End-Of-Request bucket type. The logging of a request and
402 the freeing of its pool are now done when the EOR bucket is destroyed.
403 This has the effect of delaying the logging until right after the last
404 of the response is sent; ap_core_output_filter() calls the access logger
405 indirectly when it destroys the EOR bucket. [Brian Pane]
407 *) Rewrite of logresolve support utility: IPv6 addresses are now supported
408 and the format of statistical output has changed. [Colm MacCarthaigh]
410 *) Rewrite of ap_coreoutput_filter to do nonblocking writes [Brian Pane]
412 *) Added new connection states for handler and write completion
415 *) mod_cgid: Refuse to work on Solaris 10 due to OS bugs. PR 34264.
418 *) Teach mod_ssl to use arbitrary OIDs in an SSLRequire directive,
419 allowing string-valued client certificate attributes to be used for
420 access control, as in: SSLRequire "value" in OID("1.3.6.1.4.1.18060.1")
