2 Changes with Apache 2.3.0
3 [ When backported to 2.2.x, remove entry from this file ]
5 *) mod_proxy_ajp: Do not fail if response data is sent before all request
6 data is read. PR 45911 [Ruediger Pluem]
8 *) mod_authn_core: Prevent crash when provider alias created to
9 provider which is not yet registered. [Chris Darroch]
11 *) mod_authn_core: Add AuthType of None to support disabling
12 authentication. [Chris Darroch]
14 *) core: Allow <Limit> and <LimitExcept> directives to nest, and
15 constrain their use to conform with that of other access control
16 and authorization directives. [Chris Darroch]
18 *) unixd: turn existing code into a module, and turn the set user/group
19 and chroot into a child_init function. [Nick Kew]
21 *) core: Add ap_timeout_parameter_parse to public API. [Ruediger Pluem]
23 *) mod_proxy: Prevent segmentation faults by correctly flushing all buckets
24 from the proxy backend. PR 45792 [Ruediger Pluem]
26 *) mod_dir: Support "DirectoryIndex None"
27 Suggested By André Warnier <aw ice-sa.com> [Eric Covener]
29 *) mod_proxy: Add the possibility to set the worker parameters
30 connectiontimeout and ping in milliseconds. [Ruediger Pluem]
32 *) mod_ssl: Send Content-Type application/ocsp-request for POST requests to
33 OSCP responders. PR 46014 [Dr Stephen Henson <steve openssl.org>]
35 *) Export and install the mod_rewrite.h header to ensure the optional
36 rewrite_mapfunc_t and ap_register_rewrite_mapfunc functions are
37 available to third party modules. [Graham Leggett]
39 *) Build the odbc dbd driver by default on Windows.
40 DBD_LIST is still used to build additional dbd drivers.
43 *) mod_proxy_ajp: Fix wrongly formatted requests where client
44 sets Content-Length header, but doesn't provide a body.
45 Servlet container always expects that next packet is
46 body whenever C-L is present in the headers. This can lead
47 to wrong interpretation of the packets. In this case
48 send the empty body packet, so container can deal with
51 *) mod_authnz_ldap: don't return NULL-valued environment variables to
52 other modules. PR 39045 [Francois Pesce <francois.pesce gmail.com>]
54 *) Don't adjust case in pathname components that are not of interest
55 to mod_mime. Fixes mod_negotiation's use of such components.
56 PR 43250 [Basant Kumar Kukreja <basant.kukreja sun.com>]
58 *) Add new LogFormat parameter, %k, which logs the number of
59 keepalive requests on this connection for this request..
60 [Dan Poirier <poirier pobox.com>]
62 *) Be tolerant in what you accept - accept slightly broken
63 status lines from a backend provide they include a valid status code.
64 PR 44995 [Rainer Jung <rainer.jung kippdata.de>]
66 *) New module mod_sed: filter Request/Response bodies through sed
67 [Basant Kumar Kukreja <basant.kukreja sun.com>]
69 *) mod_auth_form: Make sure that basic authentication is correctly
70 faked directly after login. [Graham Leggett]
72 *) mod_session_cookie, mod_session_dbd: Make sure cookies are set both
73 within the output headers and error output headers, so that the
74 session is maintained across redirects. [Graham Leggett]
76 *) mod_auth_form: Make sure the logged in user is populated correctly
77 after a form login. Fixes a missing REMOTE_USER variable directly
78 following a login. [Graham Leggett]
80 *) mod_session_cookie: Make sure that cookie attributes are correctly
81 included in the blank cookie when cookies are removed. This fixes an
82 inability to log out when using mod_auth_form. [Graham Leggett]
84 *) mod_autoindex: add configuration option to insert string
85 in HTML HEAD. [Nick Kew]
87 *) mod_session: Prevent a segfault when a CGI script sets a cookie with a
88 null value. [David Shane Holden <dpejesh apache.org>]
90 *) mod_headers: Prevent Header edit from processing only the first header
91 of possibly multiple headers with the same name and deleting the
92 remaining ones. PR 45333. [Ruediger Pluem]
94 *) mod_rewrite: Preserve the query string with [proxy,noescape]. PR 45247
97 *) core, authn/z: Determine registered authn/z providers directly in
98 ap_setup_auth_internal(), which allows optional functions that just
99 wrapped ap_list_provider_names() to be removed from authn/z modules.
102 *) authn/z: Convert common provider version strings to macros.
105 *) ab: Make ab.c compile on VC6. PR 45024 [Ruediger Pluem]
107 *) configure: Don't reject libtool 2.x
108 PR 44817 [Arfrever Frehtes Taifersar Arahesis <Arfrever.FTA gmail.com>]
110 *) core: When testing for slash-terminated configuration paths in
111 ap_location_walk(), don't look past the start of an empty string
112 such as that created by a <Location ""> directive.
115 *) core, mod_proxy: If a kept_body is present, it becomes safe for
116 subrequests to support message bodies. Make sure that safety
117 checks within the core and within the proxy are not triggered
118 when kept_body is present. This makes it possible to embed
119 proxied POST requests within mod_include. [Graham Leggett]
121 *) mod_auth_form: Make sure the input filter stack is properly set
122 up before reading the login form. Make sure the kept body filter
123 is correctly inserted to ensure the body can be read a second
124 time safely should the authn be successful. [Graham Leggett,
127 *) mod_request: Insert the KEPT_BODY filter via the insert_filter
128 hook instead of during fixups. Add a safety check to ensure the
129 filters cannot be inserted more than once. [Graham Leggett,
132 *) core: Do not allow Options ALL if not all options are allowed to be
133 overwritten. PR 44262 [Michał Grzędzicki <lazy iq.pl>]
135 *) ap_cache_cacheable_headers_out() will (now) always
136 merge an error heaeders _before_ clearing them and _before_
137 merging in the actual entity headers and doing normal
138 hop-by-hop cleansing. [Dirk-Willem van Gulik].
140 *) cache: retire ap_cache_cacheable_hdrs_out() which was used
141 for both in- and out-put headers; and replace it by a single
142 ap_cache_cacheable_headers() wrapped in a in- and out-put
143 specific ap_cache_cacheable_headers_in()/out(). The latter
144 which will also merge error and ensure content-type. To keep
145 cache modules consistent with ease. This API change bumps
146 up the minor MM by one [Dirk-Willem van Gulik].
148 *) mod_rewrite: Allow Cookie option to set secure and HttpOnly flags.
149 PR 44799 [Christian Wenz <christian wenz.org>]
151 *) Move the KeptBodySize directive, kept_body filters and the
152 ap_parse_request_body function out of the http module and into a
153 new module called mod_request, reducing the size of the core.
156 *) mod_dbd: Handle integer configuration directive parameters with a
159 *) Change the directives within the mod_session* modules to be valid
160 both inside and outside the location/directory sections, as
161 suggested by wrowe. [Graham Leggett]
163 *) mod_auth_form: Add a module capable of allowing end users to log
164 in using an HTML form, storing the credentials within mod_session.
167 *) Add a function to the http filters that is able to parse an HTML
168 form request with the type of application/x-www-form-urlencoded.
171 *) mod_session_crypto: Initialise SSL in the post config hook.
172 [Ruediger Pluem, Graham Leggett]
174 *) mod_session_dbd: Add a session implementation capable of storing
175 session information in a SQL database via the dbd interface. Useful
176 for sites where session privacy is important. [Graham Leggett]
178 *) mod_session_crypto: Add a session encoding implementation capable
179 of encrypting and decrypting sessions wherever they may be stored.
180 Introduces a level of privacy when sessions are stored on the
181 browser. [Graham Leggett]
183 *) mod_session_cookie: Add a session implementation capable of storing
184 session information within cookies on the browser. Useful for high
185 volume sites where server bound sessions are too resource intensive.
188 *) mod_session: Add a generic session interface to unify the different
189 attempts at saving persistent sessions across requests.
192 *) core, authn/z: Avoid calling access control hooks for internal requests
193 with configurations which match those of initial request. Revert to
194 original behaviour (call access control hooks for internal requests
195 with URIs different from initial request) if any access control hooks or
196 providers are not registered as permitting this optimization.
197 Introduce wrappers for access control hook and provider registration
198 which can accept additional mode and flag data. [Chris Darroch]
200 *) Introduced ap_expr API for expression evaluation.
201 This is adapted from mod_include, which is the first module
205 *) mod_authz_dbd: When redirecting after successful login/logout per
206 AuthzDBDRedirectQuery, do not report authorization failure, and use
207 first row returned by database query instead of last row.
210 *) mod_ldap: Correctly return all requested attribute values
211 when some attributes have a null value.
212 PR 44560 [Anders Kaseorg <anders kaseorg.com>]
214 *) core: check symlink ownership if both FollowSymlinks and
215 SymlinksIfOwnerMatch are set [Nick Kew]
217 *) core: fix origin checking in SymlinksIfOwnerMatch
218 PR 36783 [Robert L Mathews <rob-apache.org.bugs tigertech.net>]
220 *) Activate mod_cache, mod_file_cache and mod_disc_cache as part of the
221 'most' set for '--enable-modules' and '--enable-shared-mods'. Include
222 mod_mem_cache in 'all' as well. [Dirk-Willem van Gulik]
224 *) Also install mod_so.h, mod_rewrite.h and mod_cache.h; as these
225 contain public function declarations which are useful for
226 third party module authors. PR 42431 [Dirk-Willem van Gulik].
228 *) mod_dir, mod_negotiation: pass the output filter information
229 to newly created sub requests; as these are later on used
230 as true requests with an internal redirect. This allows for
231 mod_cache et.al. to trap the results of the redirect.
232 [Dirk-Willem van Gulik, Ruediger Pluem]
234 *) mod_ldap: Add support (taking advantage of the new APR capability)
235 for ldap rebind callback while chasing referrals. This allows direct
236 searches on LDAP servers (in particular MS Active Directory 2003+)
237 using referrals without the use of the global catalog.
238 PRs 26538, 40268, and 42557 [Paul J. Reder]
240 *) mod_ssl: Added server name indication support (SNI, RFC 4366).
241 PR 34607. [Kaspar Brand <asfbugz velox.ch>]. A test configuration
242 can be created with test/make_sni.sh [Dirk-Willem van Gulik].
244 *) ApacheMonitor.exe: Introduce --kill argument for use by the
245 installer. This will permit the installation tool to remove
246 all running instances before attempting to remove the .exe.
249 *) mod_ssl: Add support for OCSP validation of client certificates.
250 PR 41123. [Marc Stern <marc.stern approach.be>, Joe Orton]
252 *) mod_serf: New module for Reverse Proxying. [Paul Querna]
254 *) core: Add the option to keep aside a request body up to a certain
255 size that would otherwise be discarded, to be consumed by filters
256 such as mod_include. When enabled for a directory, POST requests
257 to shtml files can be passed through to embedded scripts as POST
258 requests, rather being downgraded to GET requests. [Graham Leggett]
260 *) mod_ssl: Fix TLS upgrade (RFC 2817) support. PR 41231. [Joe Orton]
262 *) scoreboard: Correctly declare ap_time_process_request.
263 PR 43789 [Tom Donovan <Tom.Donovan acm.org>]
265 *) core; scoreboard: ap_get_scoreboard_worker(sbh) now takes the sbh member
266 from the connection rec, ap_get_scoreboard_worker(proc, thread) will now
267 provide the unusual legacy lookup. [William Rowe]
269 *) mpm winnt: fix null pointer dereference
270 PR 42572 [Davi Arnaut]
272 *) mod_authnz_ldap, mod_authn_dbd: Tidy up the code to expose authn
273 parameters to the environment. Improve portability to
274 EBCDIC machines by using apr_toupper(). [Martin Kraemer]
276 *) mod_ldap, mod_authnzldap: Add support for nested groups (i.e. the ability
277 to authorize an authenticated user via a "require ldap-group X" directive
278 where the user is not in group X, but is in a subgroup contained in X.
279 PR 42891 [Paul J. Reder]
281 *) mod_ssl: Add support for caching SSL Sessions in memcached. [Paul Querna]
283 *) mod_ldap: Fix the search limit parameter to ldap_search_ext_s()
284 for SDKs that define LDAP_NO_LIMIT to something other than -1.
285 [David Jones <oscaremma gmail.com>]
287 *) apxs: Enhance -q flag to print all known variables and their values
288 when invoked without variable name(s).
289 [William Rowe, Sander Temme]
291 *) apxs: Eliminate run-time check for mod_so. PR 40653.
292 [David M. Lee <dmlee crossroads.com>]
294 *) beos MPM: Create pmain pool and run modules' child_init hooks when
295 entering ap_mpm_run(), then destroy pmain when exiting ap_mpm_run().
298 *) netware MPM: Destroy pmain pool when exiting ap_mpm_run() so that
299 cleanups registered in modules' child_init hooks are performed.
302 *) mod_dbd: Stash DBD connections in request_config of initial request
303 only, or else sub-requests and internal redirections may cause
304 entire DBD pool to be stashed in a single HTTP request. [Chris Darroch]
306 *) Fix issue which could cause error messages to be written to access logs
307 on Win32. PR 40476. [Tom Donovan <Tom.Donovan acm.org>]
309 *) The LockFile directive, which specifies the location of
310 the accept() mutex lockfile, is deprecated. Instead, the
311 AcceptMutex directive now takes an optional lockfile
312 location parameter, ala SSLMutex. [Jim Jagielski]
314 *) mod_authn_dbd: Export any additional columns queried in the SQL select
315 into the environment with the name AUTHENTICATE_<COLUMN>. This brings
316 mod_authn_dbd behaviour in line with mod_authnz_ldap. [Graham Leggett]
318 *) mod_dbd: Key the storage of prepared statements on the hex string
319 value of server_rec, rather than the server name, as the server name
320 may change (eg when the server name is set) at any time, causing
321 weird behaviour in modules dependent on mod_dbd. [Graham Leggett]
323 *) mod_proxy_fcgi: Added win32 build. [Mladen Turk]
325 *) sendfile_nonblocking() takes the _brigade_ as an argument, gets
326 the first bucket from the brigade, finds it not to be a FILE
327 bucket and barfs. The fix is to pass a bucket rather than a brigade.
328 [Niklas Edmundsson <nikke acc.umu.se>]
330 *) mod_rewrite: support rewritemap by SQL query [Nick Kew]
332 *) ap_get_server_version() has been removed. Third-party modules must
333 now use ap_get_server_banner() or ap_get_server_description().
336 *) All MPMs: Introduce a check_config phase between pre_config and
337 open_logs, to allow modules to review interdependent configuration
338 directive values and adjust them while messages can still be logged
339 to the console. Handle relevant MPM directives during this phase
340 and format messages for both the console and the error log, as
341 appropriate. [Chris Darroch]
343 *) mod_proxy: don't URLencode tilde in path component
344 [Stijn Hoop <stijn sandcat.nl>]
346 *) mpm_winnt: Fix return values from wait_for_many_objects.
347 The return value is index to the signaled thread in the
348 creted_threads array. We can not use WAIT_TIMEOUT because
349 his value is defined as 258, thus limiting the MaxThreads
350 to that value. [Mladen Turk]
352 *) core: Do not allow internal redirects like the DirectoryIndex of mod_dir
353 to circumvent the symbolic link checks imposed by FollowSymLinks and
354 SymLinksIfOwnerMatch. [Nick Kew, Ruediger Pluem, William Rowe]
356 *) New SSLLogLevelDebugDump [ None (default) | IO (not bytes) | Bytes ]
357 configures the I/O Dump of SSL traffic, when LogLevel is set to Debug.
358 The default is none as this is far greater debugging resolution than
359 the typical administrator is prepared to untangle. [William Rowe]
361 *) mod_disk_cache: If possible, check if the size of an object to cache is
362 within the configured boundaries before actually saving data.
363 [Niklas Edmundsson <nikke acc.umu.se>]
365 *) mod_cache: Convert all values to seconds before comparing them when
366 checking whether to send a Warning header for a stale response.
367 PR 39713. [Owen Taylor <otaylor redhat.com>]
369 *) mod_disk_cache: Delete temporary files if they cannot be renamed to their
370 final name. [Davi Arnaut <davi haxent.com.br>]
372 *) Worker and event MPMs: Remove improper scoreboard updates which were
373 performed in the event of a fork() failure. [Chris Darroch]
375 *) Add support for fcgi:// proxies to mod_rewrite.
376 [Markus Schiegl <ms schiegl.com>]
378 *) Remove incorrect comments from scoreboard.h regarding conditional
379 loading of worker_score structure with mod_status, and remove unused
380 definitions relating to old life_status field.
381 [Chris Darroch <chrisd pearsoncmg.com>]
383 *) Remove allocation of memory for unused array of lb_score pointers
384 in ap_init_scoreboard(). [Chris Darroch <chrisd pearsoncmg.com>]
386 *) Add mod_proxy_fcgi, a FastCGI back end for mod_proxy.
387 [Garrett Rooney, Jim Jagielski, Paul Querna]
389 *) Event MPM: Fill in the scoreboard's tid field. PR 38736.
390 [Chris Darroch <chrisd pearsoncmg.com>]
392 *) mod_charset_lite: Remove Content-Length when output filter can
393 invalidate it. Warn when input filter can invalidate it.
396 *) Authz: Add the new module mod_authn_core that will provide common
397 authn directives such as 'AuthType', 'AuthName'. Move the directives
398 'AuthType' and 'AuthName' out of the core module and merge mod_authz_alias
399 into mod_authn_core. [Brad Nicholes]
401 *) Authz: Move the directives 'Order', 'Allow', 'Deny' and 'Satisfy'
402 into the new module mod_access_compat which can be loaded to provide
403 support for these directives.
406 *) Authz: Move the 'Require' directive from the core module as well as
407 add the directives '<SatisfyAll>', '<SatisfyOne>', '<RequireAlias>'
408 and 'Reject' to mod_authz_core. The new directives introduce 'AND/OR'
409 logic into the authorization processing. [Brad Nicholes]
411 *) Authz: Add the new module mod_authz_core which acts as the
412 authorization provider vector and contains common authz
413 directives. [Brad Nicholes]
415 *) Authz: Renamed mod_authz_dbm authz providers from 'group' and
416 'file-group' to 'dbm-group' and 'dbm-file-group'. [Brad Nicholes]
418 *) Authz: Added the new authz providers 'env', 'ip', 'host', 'all' to handle
419 host-based access control provided by mod_authz_host and invoked
420 through the 'Require' directive. [Brad Nicholes]
422 *) Authz: Convert all of the authz modules from hook based to
423 provider based. [Brad Nicholes]
425 *) mod_cache: Add CacheMinExpire directive to set the minimum time in
426 seconds to cache a document.
427 [Brian Akins <brian.akins turner.com>, Ruediger Pluem]
429 *) mod_authz_dbd: SQL authz with Login/Session support [Nick Kew]
431 *) Fix typo in ProxyStatus syntax error message.
432 [Christophe Jaillet <christophe.jaillet wanadoo.fr>]
434 *) Asynchronous write completion for the Event MPM. [Brian Pane]
436 *) Added an End-Of-Request bucket type. The logging of a request and
437 the freeing of its pool are now done when the EOR bucket is destroyed.
438 This has the effect of delaying the logging until right after the last
439 of the response is sent; ap_core_output_filter() calls the access logger
440 indirectly when it destroys the EOR bucket. [Brian Pane]
442 *) Rewrite of logresolve support utility: IPv6 addresses are now supported
443 and the format of statistical output has changed. [Colm MacCarthaigh]
445 *) Rewrite of ap_coreoutput_filter to do nonblocking writes [Brian Pane]
447 *) Added new connection states for handler and write completion
450 *) mod_cgid: Refuse to work on Solaris 10 due to OS bugs. PR 34264.
453 *) Teach mod_ssl to use arbitrary OIDs in an SSLRequire directive,
454 allowing string-valued client certificate attributes to be used for
455 access control, as in: SSLRequire "value" in OID("1.3.6.1.4.1.18060.1")
