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