2 Changes with Apache 2.3.0
3 [ When backported to 2.2.x, remove entry from this file ]
5 *) mod_ssl: Send Content-Type application/ocsp-request for POST requests to
6 OSCP responders. PR 46014 [Dr Stephen Henson <steve openssl.org>]
8 *) Export and install the mod_rewrite.h header to ensure the optional
9 rewrite_mapfunc_t and ap_register_rewrite_mapfunc functions are
10 available to third party modules. [Graham Leggett]
12 *) Build the odbc dbd driver by default on Windows.
13 DBD_LIST is still used to build additional dbd drivers.
16 *) Worker MPM: Crosscheck that idle workers are still available before using
17 them and thus preventing an overflow of the worker queue which causes
18 a SegFault. PR 45605 [Denis Ustimenko <denusk gmail.com>]
20 *) mod_proxy_ajp: Fix wrongly formatted requests where client
21 sets Content-Length header, but doesn't provide a body.
22 Servlet container always expects that next packet is
23 body whenever C-L is present in the headers. This can lead
24 to wrong interpretation of the packets. In this case
25 send the empty body packet, so container can deal with
28 *) mod_authnz_ldap: don't return NULL-valued environment variables to
29 other modules. PR 39045 [Francois Pesce <francois.pesce gmail.com>]
31 *) Don't adjust case in pathname components that are not of interest
32 to mod_mime. Fixes mod_negotiation's use of such components.
33 PR 43250 [Basant Kumar Kukreja <basant.kukreja sun.com>]
35 *) Add new LogFormat parameter, %k, which logs the number of
36 keepalive requests on this connection for this request..
37 [Dan Poirier <poirier pobox.com>]
39 *) Be tolerant in what you accept - accept slightly broken
40 status lines from a backend provide they include a valid status code.
41 PR 44995 [Rainer Jung <rainer.jung kippdata.de>]
43 *) New module mod_sed: filter Request/Response bodies through sed
44 [Basant Kumar Kukreja <basant.kukreja sun.com>]
46 *) mod_auth_form: Make sure that basic authentication is correctly
47 faked directly after login. [Graham Leggett]
49 *) mod_session_cookie, mod_session_dbd: Make sure cookies are set both
50 within the output headers and error output headers, so that the
51 session is maintained across redirects. [Graham Leggett]
53 *) mod_auth_form: Make sure the logged in user is populated correctly
54 after a form login. Fixes a missing REMOTE_USER variable directly
55 following a login. [Graham Leggett]
57 *) mod_session_cookie: Make sure that cookie attributes are correctly
58 included in the blank cookie when cookies are removed. This fixes an
59 inability to log out when using mod_auth_form. [Graham Leggett]
61 *) mod_autoindex: add configuration option to insert string
62 in HTML HEAD. [Nick Kew]
64 *) mod_ssl: implement dynamic mutex callbacks for the benefit of
65 OpenSSL. [Sander Temme]
67 *) mod_session: Prevent a segfault when a CGI script sets a cookie with a
68 null value. [David Shane Holden <dpejesh apache.org>]
70 *) mod_headers: Prevent Header edit from processing only the first header
71 of possibly multiple headers with the same name and deleting the
72 remaining ones. PR 45333. [Ruediger Pluem]
74 *) mod_rewrite: Preserve the query string with [proxy,noescape]. PR 45247
77 *) core, authn/z: Determine registered authn/z providers directly in
78 ap_setup_auth_internal(), which allows optional functions that just
79 wrapped ap_list_provider_names() to be removed from authn/z modules.
82 *) authn/z: Convert common provider version strings to macros.
85 *) ab: Make ab.c compile on VC6. PR 45024 [Ruediger Pluem]
87 *) configure: Don't reject libtool 2.x
88 PR 44817 [Arfrever Frehtes Taifersar Arahesis <Arfrever.FTA gmail.com>]
90 *) core: When testing for slash-terminated configuration paths in
91 ap_location_walk(), don't look past the start of an empty string
92 such as that created by a <Location ""> directive.
95 *) core, mod_proxy: If a kept_body is present, it becomes safe for
96 subrequests to support message bodies. Make sure that safety
97 checks within the core and within the proxy are not triggered
98 when kept_body is present. This makes it possible to embed
99 proxied POST requests within mod_include. [Graham Leggett]
101 *) mod_auth_form: Make sure the input filter stack is properly set
102 up before reading the login form. Make sure the kept body filter
103 is correctly inserted to ensure the body can be read a second
104 time safely should the authn be successful. [Graham Leggett,
107 *) mod_request: Insert the KEPT_BODY filter via the insert_filter
108 hook instead of during fixups. Add a safety check to ensure the
109 filters cannot be inserted more than once. [Graham Leggett,
112 *) core: Do not allow Options ALL if not all options are allowed to be
113 overwritten. PR 44262 [Michał Grzędzicki <lazy iq.pl>]
115 *) ap_cache_cacheable_headers_out() will (now) always
116 merge an error heaeders _before_ clearing them and _before_
117 merging in the actual entity headers and doing normal
118 hop-by-hop cleansing. [Dirk-Willem van Gulik].
120 *) cache: retire ap_cache_cacheable_hdrs_out() which was used
121 for both in- and out-put headers; and replace it by a single
122 ap_cache_cacheable_headers() wrapped in a in- and out-put
123 specific ap_cache_cacheable_headers_in()/out(). The latter
124 which will also merge error and ensure content-type. To keep
125 cache modules consistent with ease. This API change bumps
126 up the minor MM by one [Dirk-Willem van Gulik].
128 *) mod_rewrite: Allow Cookie option to set secure and HttpOnly flags.
129 PR 44799 [Christian Wenz <christian wenz.org>]
131 *) Move the KeptBodySize directive, kept_body filters and the
132 ap_parse_request_body function out of the http module and into a
133 new module called mod_request, reducing the size of the core.
136 *) mod_dbd: Handle integer configuration directive parameters with a
139 *) Change the directives within the mod_session* modules to be valid
140 both inside and outside the location/directory sections, as
141 suggested by wrowe. [Graham Leggett]
143 *) mod_auth_form: Add a module capable of allowing end users to log
144 in using an HTML form, storing the credentials within mod_session.
147 *) Add a function to the http filters that is able to parse an HTML
148 form request with the type of application/x-www-form-urlencoded.
151 *) mod_session_crypto: Initialise SSL in the post config hook.
152 [Ruediger Pluem, Graham Leggett]
154 *) mod_session_dbd: Add a session implementation capable of storing
155 session information in a SQL database via the dbd interface. Useful
156 for sites where session privacy is important. [Graham Leggett]
158 *) mod_session_crypto: Add a session encoding implementation capable
159 of encrypting and decrypting sessions wherever they may be stored.
160 Introduces a level of privacy when sessions are stored on the
161 browser. [Graham Leggett]
163 *) mod_session_cookie: Add a session implementation capable of storing
164 session information within cookies on the browser. Useful for high
165 volume sites where server bound sessions are too resource intensive.
168 *) mod_session: Add a generic session interface to unify the different
169 attempts at saving persistent sessions across requests.
172 *) core, authn/z: Avoid calling access control hooks for internal requests
173 with configurations which match those of initial request. Revert to
174 original behaviour (call access control hooks for internal requests
175 with URIs different from initial request) if any access control hooks or
176 providers are not registered as permitting this optimization.
177 Introduce wrappers for access control hook and provider registration
178 which can accept additional mode and flag data. [Chris Darroch]
180 *) Introduced ap_expr API for expression evaluation.
181 This is adapted from mod_include, which is the first module
185 *) mod_authz_dbd: When redirecting after successful login/logout per
186 AuthzDBDRedirectQuery, do not report authorization failure, and use
187 first row returned by database query instead of last row.
190 *) mod_ldap: Correctly return all requested attribute values
191 when some attributes have a null value.
192 PR 44560 [Anders Kaseorg <anders kaseorg.com>]
194 *) core: check symlink ownership if both FollowSymlinks and
195 SymlinksIfOwnerMatch are set [Nick Kew]
197 *) core: fix origin checking in SymlinksIfOwnerMatch
198 PR 36783 [Robert L Mathews <rob-apache.org.bugs tigertech.net>]
200 *) Activate mod_cache, mod_file_cache and mod_disc_cache as part of the
201 'most' set for '--enable-modules' and '--enable-shared-mods'. Include
202 mod_mem_cache in 'all' as well. [Dirk-Willem van Gulik]
204 *) Also install mod_so.h, mod_rewrite.h and mod_cache.h; as these
205 contain public function declarations which are useful for
206 third party module authors. PR 42431 [Dirk-Willem van Gulik].
208 *) mod_dir, mod_negotiation: pass the output filter information
209 to newly created sub requests; as these are later on used
210 as true requests with an internal redirect. This allows for
211 mod_cache et.al. to trap the results of the redirect.
212 [Dirk-Willem van Gulik, Ruediger Pluem]
214 *) mod_ldap: Add support (taking advantage of the new APR capability)
215 for ldap rebind callback while chasing referrals. This allows direct
216 searches on LDAP servers (in particular MS Active Directory 2003+)
217 using referrals without the use of the global catalog.
218 PRs 26538, 40268, and 42557 [Paul J. Reder]
220 *) mod_ssl: Added server name indication support (SNI, RFC 4366).
221 PR 34607. [Kaspar Brand <asfbugz velox.ch>]. A test configuration
222 can be created with test/make_sni.sh [Dirk-Willem van Gulik].
224 *) ApacheMonitor.exe: Introduce --kill argument for use by the
225 installer. This will permit the installation tool to remove
226 all running instances before attempting to remove the .exe.
229 *) mod_ssl: Add support for OCSP validation of client certificates.
230 PR 41123. [Marc Stern <marc.stern approach.be>, Joe Orton]
232 *) mod_serf: New module for Reverse Proxying. [Paul Querna]
234 *) core: Add the option to keep aside a request body up to a certain
235 size that would otherwise be discarded, to be consumed by filters
236 such as mod_include. When enabled for a directory, POST requests
237 to shtml files can be passed through to embedded scripts as POST
238 requests, rather being downgraded to GET requests. [Graham Leggett]
240 *) mod_ssl: Fix TLS upgrade (RFC 2817) support. PR 41231. [Joe Orton]
242 *) scoreboard: Correctly declare ap_time_process_request.
243 PR 43789 [Tom Donovan <Tom.Donovan acm.org>]
245 *) core; scoreboard: ap_get_scoreboard_worker(sbh) now takes the sbh member
246 from the connection rec, ap_get_scoreboard_worker(proc, thread) will now
247 provide the unusual legacy lookup. [William Rowe]
249 *) mpm winnt: fix null pointer dereference
250 PR 42572 [Davi Arnaut]
252 *) mod_authnz_ldap, mod_authn_dbd: Tidy up the code to expose authn
253 parameters to the environment. Improve portability to
254 EBCDIC machines by using apr_toupper(). [Martin Kraemer]
256 *) mod_ldap, mod_authnzldap: Add support for nested groups (i.e. the ability
257 to authorize an authenticated user via a "require ldap-group X" directive
258 where the user is not in group X, but is in a subgroup contained in X.
259 PR 42891 [Paul J. Reder]
261 *) mod_ssl: Add support for caching SSL Sessions in memcached. [Paul Querna]
263 *) mod_ldap: Fix the search limit parameter to ldap_search_ext_s()
264 for SDKs that define LDAP_NO_LIMIT to something other than -1.
265 [David Jones <oscaremma gmail.com>]
267 *) apxs: Enhance -q flag to print all known variables and their values
268 when invoked without variable name(s).
269 [William Rowe, Sander Temme]
271 *) apxs: Eliminate run-time check for mod_so. PR 40653.
272 [David M. Lee <dmlee crossroads.com>]
274 *) beos MPM: Create pmain pool and run modules' child_init hooks when
275 entering ap_mpm_run(), then destroy pmain when exiting ap_mpm_run().
278 *) netware MPM: Destroy pmain pool when exiting ap_mpm_run() so that
279 cleanups registered in modules' child_init hooks are performed.
282 *) mod_dbd: Stash DBD connections in request_config of initial request
283 only, or else sub-requests and internal redirections may cause
284 entire DBD pool to be stashed in a single HTTP request. [Chris Darroch]
286 *) Fix issue which could cause error messages to be written to access logs
287 on Win32. PR 40476. [Tom Donovan <Tom.Donovan acm.org>]
289 *) The LockFile directive, which specifies the location of
290 the accept() mutex lockfile, is deprecated. Instead, the
291 AcceptMutex directive now takes an optional lockfile
292 location parameter, ala SSLMutex. [Jim Jagielski]
294 *) mod_authn_dbd: Export any additional columns queried in the SQL select
295 into the environment with the name AUTHENTICATE_<COLUMN>. This brings
296 mod_authn_dbd behaviour in line with mod_authnz_ldap. [Graham Leggett]
298 *) mod_dbd: Key the storage of prepared statements on the hex string
299 value of server_rec, rather than the server name, as the server name
300 may change (eg when the server name is set) at any time, causing
301 weird behaviour in modules dependent on mod_dbd. [Graham Leggett]
303 *) mod_proxy_fcgi: Added win32 build. [Mladen Turk]
305 *) sendfile_nonblocking() takes the _brigade_ as an argument, gets
306 the first bucket from the brigade, finds it not to be a FILE
307 bucket and barfs. The fix is to pass a bucket rather than a brigade.
308 [Niklas Edmundsson <nikke acc.umu.se>]
310 *) mod_rewrite: support rewritemap by SQL query [Nick Kew]
312 *) ap_get_server_version() has been removed. Third-party modules must
313 now use ap_get_server_banner() or ap_get_server_description().
316 *) All MPMs: Introduce a check_config phase between pre_config and
317 open_logs, to allow modules to review interdependent configuration
318 directive values and adjust them while messages can still be logged
319 to the console. Handle relevant MPM directives during this phase
320 and format messages for both the console and the error log, as
321 appropriate. [Chris Darroch]
323 *) mod_proxy: don't URLencode tilde in path component
324 [Stijn Hoop <stijn sandcat.nl>]
326 *) mpm_winnt: Fix return values from wait_for_many_objects.
327 The return value is index to the signaled thread in the
328 creted_threads array. We can not use WAIT_TIMEOUT because
329 his value is defined as 258, thus limiting the MaxThreads
330 to that value. [Mladen Turk]
332 *) core: Do not allow internal redirects like the DirectoryIndex of mod_dir
333 to circumvent the symbolic link checks imposed by FollowSymLinks and
334 SymLinksIfOwnerMatch. [Nick Kew, Ruediger Pluem, William Rowe]
336 *) New SSLLogLevelDebugDump [ None (default) | IO (not bytes) | Bytes ]
337 configures the I/O Dump of SSL traffic, when LogLevel is set to Debug.
338 The default is none as this is far greater debugging resolution than
339 the typical administrator is prepared to untangle. [William Rowe]
341 *) mod_disk_cache: If possible, check if the size of an object to cache is
342 within the configured boundaries before actually saving data.
343 [Niklas Edmundsson <nikke acc.umu.se>]
345 *) mod_cache: Convert all values to seconds before comparing them when
346 checking whether to send a Warning header for a stale response.
347 PR 39713. [Owen Taylor <otaylor redhat.com>]
349 *) mod_disk_cache: Delete temporary files if they cannot be renamed to their
350 final name. [Davi Arnaut <davi haxent.com.br>]
352 *) Worker and event MPMs: Remove improper scoreboard updates which were
353 performed in the event of a fork() failure. [Chris Darroch]
355 *) Add support for fcgi:// proxies to mod_rewrite.
356 [Markus Schiegl <ms schiegl.com>]
358 *) Remove incorrect comments from scoreboard.h regarding conditional
359 loading of worker_score structure with mod_status, and remove unused
360 definitions relating to old life_status field.
361 [Chris Darroch <chrisd pearsoncmg.com>]
363 *) Remove allocation of memory for unused array of lb_score pointers
364 in ap_init_scoreboard(). [Chris Darroch <chrisd pearsoncmg.com>]
366 *) Add mod_proxy_fcgi, a FastCGI back end for mod_proxy.
367 [Garrett Rooney, Jim Jagielski, Paul Querna]
369 *) Event MPM: Fill in the scoreboard's tid field. PR 38736.
370 [Chris Darroch <chrisd pearsoncmg.com>]
372 *) mod_charset_lite: Remove Content-Length when output filter can
373 invalidate it. Warn when input filter can invalidate it.
376 *) Authz: Add the new module mod_authn_core that will provide common
377 authn directives such as 'AuthType', 'AuthName'. Move the directives
378 'AuthType' and 'AuthName' out of the core module and merge mod_authz_alias
379 into mod_authn_core. [Brad Nicholes]
381 *) Authz: Move the directives 'Order', 'Allow', 'Deny' and 'Satisfy'
382 into the new module mod_access_compat which can be loaded to provide
383 support for these directives.
386 *) Authz: Move the 'Require' directive from the core module as well as
387 add the directives '<SatisfyAll>', '<SatisfyOne>', '<RequireAlias>'
388 and 'Reject' to mod_authz_core. The new directives introduce 'AND/OR'
389 logic into the authorization processing. [Brad Nicholes]
391 *) Authz: Add the new module mod_authz_core which acts as the
392 authorization provider vector and contains common authz
393 directives. [Brad Nicholes]
395 *) Authz: Renamed mod_authz_dbm authz providers from 'group' and
396 'file-group' to 'dbm-group' and 'dbm-file-group'. [Brad Nicholes]
398 *) Authz: Added the new authz providers 'env', 'ip', 'host', 'all' to handle
399 host-based access control provided by mod_authz_host and invoked
400 through the 'Require' directive. [Brad Nicholes]
402 *) Authz: Convert all of the authz modules from hook based to
403 provider based. [Brad Nicholes]
405 *) mod_cache: Add CacheMinExpire directive to set the minimum time in
406 seconds to cache a document.
407 [Brian Akins <brian.akins turner.com>, Ruediger Pluem]
409 *) mod_authz_dbd: SQL authz with Login/Session support [Nick Kew]
411 *) Fix typo in ProxyStatus syntax error message.
412 [Christophe Jaillet <christophe.jaillet wanadoo.fr>]
414 *) Asynchronous write completion for the Event MPM. [Brian Pane]
416 *) Added an End-Of-Request bucket type. The logging of a request and
417 the freeing of its pool are now done when the EOR bucket is destroyed.
418 This has the effect of delaying the logging until right after the last
419 of the response is sent; ap_core_output_filter() calls the access logger
420 indirectly when it destroys the EOR bucket. [Brian Pane]
422 *) Rewrite of logresolve support utility: IPv6 addresses are now supported
423 and the format of statistical output has changed. [Colm MacCarthaigh]
425 *) Rewrite of ap_coreoutput_filter to do nonblocking writes [Brian Pane]
427 *) Added new connection states for handler and write completion
430 *) mod_cgid: Refuse to work on Solaris 10 due to OS bugs. PR 34264.
433 *) Teach mod_ssl to use arbitrary OIDs in an SSLRequire directive,
434 allowing string-valued client certificate attributes to be used for
435 access control, as in: SSLRequire "value" in OID("1.3.6.1.4.1.18060.1")
