2 Changes with Apache 2.3.0
3 [ When backported to 2.2.x, remove entry from this file ]
5 *) core, authn/z: Determine registered authn/z providers directly in
6 ap_setup_auth_internal(), which allows optional functions that just
7 wrapped ap_list_provider_names() to be removed from authn/z modules.
10 *) authn/z: Convert common provider version strings to macros.
13 *) http_filters: Don't return 100-continue on redirects. PR 43711
16 *) ab: Make ab.c compile on VC6. PR 45024 [Ruediger Pluem]
18 *) configure: Don't reject libtool 2.x
19 PR 44817 [Arfrever Frehtes Taifersar Arahesis <Arfrever.FTA gmail.com>]
21 *) suexec: When group is given as a numeric gid, validate it by looking up
22 the actual group name such that the name can be used in log entries.
23 PR 7862 [<y-koga apache.or.jp>, Leif W <warp-9.9 usa.net>]
25 *) ab: Improve client performance by clearing connection pool instead
26 of destroying it. PR 40054 [Brad Roberts <braddr puremagic.com>]
28 *) ab: Don't stop sending a request if EAGAIN is returned, which
29 will only happen if both the write and subsequent wait are
30 returning EAGAIN, and count posted bytes correctly when the initial
31 write of a request is not complete. PR 10038, 38861, 39679
32 [Patrick McManus <mcmanus datapower.com>,
33 Stefan Fleiter <stefan.fleiter web.de>,
34 Davanum Srinivas, Roy T. Fielding]
36 *) ab: Overhaul stats collection and reporting to avoid integer
37 truncation and time divisions within the test loop, retain
38 native time resolution until output, remove unused data,
39 consistently round milliseconds, and generally avoid losing
40 accuracy of calculation due to type casts. PR 44878, 44931.
43 *) core: When testing for slash-terminated configuration paths in
44 ap_location_walk(), don't look past the start of an empty string
45 such as that created by a <Location ""> directive.
48 *) core, mod_proxy: If a kept_body is present, it becomes safe for
49 subrequests to support message bodies. Make sure that safety
50 checks within the core and within the proxy are not triggered
51 when kept_body is present. This makes it possible to embed
52 proxied POST requests within mod_include. [Graham Leggett]
54 *) mod_auth_form: Make sure the input filter stack is properly set
55 up before reading the login form. Make sure the kept body filter
56 is correctly inserted to ensure the body can be read a second
57 time safely should the authn be successful. [Graham Leggett,
60 *) mod_request: Insert the KEPT_BODY filter via the insert_filter
61 hook instead of during fixups. Add a safety check to ensure the
62 filters cannot be inserted more than once. [Graham Leggett,
65 *) core: Do not allow Options ALL if not all options are allowed to be
66 overwritten. PR 44262 [Michał Grzędzicki <lazy iq.pl>]
68 *) ap_cache_cacheable_headers_out() will (now) always
69 merge an error heaeders _before_ clearing them and _before_
70 merging in the actual entity headers and doing normal
71 hop-by-hop cleansing. [Dirk-Willem van Gulik].
73 *) cache: retire ap_cache_cacheable_hdrs_out() which was used
74 for both in- and out-put headers; and replace it by a single
75 ap_cache_cacheable_headers() wrapped in a in- and out-put
76 specific ap_cache_cacheable_headers_in()/out(). The latter
77 which will also merge error and ensure content-type. To keep
78 cache modules consistent with ease. This API change bumps
79 up the minor MM by one [Dirk-Willem van Gulik].
81 *) mod_rewrite: Allow Cookie option to set secure and HttpOnly flags.
82 PR 44799 [Christian Wenz <christian wenz.org>]
84 *) Move the KeptBodySize directive, kept_body filters and the
85 ap_parse_request_body function out of the http module and into a
86 new module called mod_request, reducing the size of the core.
89 *) mod_dbd: Handle integer configuration directive parameters with a
92 *) Change the directives within the mod_session* modules to be valid
93 both inside and outside the location/directory sections, as
94 suggested by wrowe. [Graham Leggett]
96 *) mod_auth_form: Add a module capable of allowing end users to log
97 in using an HTML form, storing the credentials within mod_session.
100 *) Add a function to the http filters that is able to parse an HTML
101 form request with the type of application/x-www-form-urlencoded.
104 *) mod_session_crypto: Initialise SSL in the post config hook.
105 [Ruediger Pluem, Graham Leggett]
107 *) mod_session_dbd: Add a session implementation capable of storing
108 session information in a SQL database via the dbd interface. Useful
109 for sites where session privacy is important. [Graham Leggett]
111 *) mod_session_crypto: Add a session encoding implementation capable
112 of encrypting and decrypting sessions wherever they may be stored.
113 Introduces a level of privacy when sessions are stored on the
114 browser. [Graham Leggett]
116 *) mod_session_cookie: Add a session implementation capable of storing
117 session information within cookies on the browser. Useful for high
118 volume sites where server bound sessions are too resource intensive.
121 *) mod_session: Add a generic session interface to unify the different
122 attempts at saving persistent sessions across requests.
125 *) core, authn/z: Avoid calling access control hooks for internal requests
126 with configurations which match those of initial request. Revert to
127 original behaviour (call access control hooks for internal requests
128 with URIs different from initial request) if any access control hooks or
129 providers are not registered as permitting this optimization.
130 Introduce wrappers for access control hook and provider registration
131 which can accept additional mode and flag data. [Chris Darroch]
133 *) mod_dav: Return "method not allowed" if the destination URI of a WebDAV
134 copy / move operation is no DAV resource. PR 44734 [Ruediger Pluem]
136 *) Introduced ap_expr API for expression evaluation.
137 This is adapted from mod_include, which is the first module
141 *) mod_authz_dbd: When redirecting after successful login/logout per
142 AuthzDBDRedirectQuery, do not report authorization failure, and use
143 first row returned by database query instead of last row.
146 *) mod_rewrite: Initialize hash needed by ap_register_rewrite_mapfunc early
147 enough. PR 44641 [Daniel Lescohier <daniel.lescohier cnet.com>]
149 *) mod_cache: Handle If-Range correctly if the cached resource was stale.
150 PR 44579 [Ruediger Pluem]
152 *) mod_ldap: Correctly return all requested attribute values
153 when some attributes have a null value.
154 PR 44560 [Anders Kaseorg <anders kaseorg.com>]
156 *) core: check symlink ownership if both FollowSymlinks and
157 SymlinksIfOwnerMatch are set [Nick Kew]
159 *) core: fix origin checking in SymlinksIfOwnerMatch
160 PR 36783 [Robert L Mathews <rob-apache.org.bugs tigertech.net>]
162 *) mod_proxy: Do not try a direct connection if the connection via a
163 remote proxy failed before and the request has a request body.
166 *) Activate mod_cache, mod_file_cache and mod_disc_cache as part of the
167 'most' set for '--enable-modules' and '--enable-shared-mods'. Include
168 mod_mem_cache in 'all' as well. [Dirk-Willem van Gulik]
170 *) Also install mod_so.h, mod_rewrite.h and mod_cache.h; as these
171 contain public function declarations which are useful for
172 third party module authors. PR 42431 [Dirk-Willem van Gulik].
174 *) mod_dir, mod_negotiation: pass the output filter information
175 to newly created sub requests; as these are later on used
176 as true requests with an internal redirect. This allows for
177 mod_cache et.al. to trap the results of the redirect.
178 [Dirk-Willem van Gulik, Ruediger Pluem]
180 *) mod_proxy_ajp: Do not retry request in the case that we either failed to
181 sent a part of the request body or if the request is not idempotent.
182 PR 44334 [Ruediger Pluem]
184 *) mod_ldap: Add support (taking advantage of the new APR capability)
185 for ldap rebind callback while chasing referrals. This allows direct
186 searches on LDAP servers (in particular MS Active Directory 2003+)
187 using referrals without the use of the global catalog.
188 PRs 26538, 40268, and 42557 [Paul J. Reder]
190 *) Support chroot on Unix-family platforms
191 PR 43596 [Dimitar Pashev <mitko banksoft-bg.com>]
193 *) mod_ssl: Added server name indication support (SNI, RFC 4366).
194 PR 34607. [Kaspar Brand <asfbugz velox.ch>]. A test configuration
195 can be created with test/make_sni.sh [Dirk-Willem van Gulik].
197 *) ApacheMonitor.exe: Introduce --kill argument for use by the
198 installer. This will permit the installation tool to remove
199 all running instances before attempting to remove the .exe.
202 *) mod_ssl: Add support for OCSP validation of client certificates.
203 PR 41123. [Marc Stern <marc.stern approach.be>, Joe Orton]
205 *) mod_unique_id: Fix timestamp value in UNIQUE_ID.
206 PR 37064 [Kobayashi <kobayashi firstserver.co.jp>]
208 *) mod_serf: New module for Reverse Proxying. [Paul Querna]
210 *) core: Add the option to keep aside a request body up to a certain
211 size that would otherwise be discarded, to be consumed by filters
212 such as mod_include. When enabled for a directory, POST requests
213 to shtml files can be passed through to embedded scripts as POST
214 requests, rather being downgraded to GET requests. [Graham Leggett]
216 *) mod_ssl: Fix TLS upgrade (RFC 2817) support. PR 41231. [Joe Orton]
218 *) scoreboard: Correctly declare ap_time_process_request.
219 PR 43789 [Tom Donovan <Tom.Donovan acm.org>]
221 *) core; scoreboard: ap_get_scoreboard_worker(sbh) now takes the sbh member
222 from the connection rec, ap_get_scoreboard_worker(proc, thread) will now
223 provide the unusual legacy lookup. [William Rowe]
225 *) mpm winnt: fix null pointer dereference
226 PR 42572 [Davi Arnaut]
228 *) mod_authnz_ldap, mod_authn_dbd: Tidy up the code to expose authn
229 parameters to the environment. Improve portability to
230 EBCDIC machines by using apr_toupper(). [Martin Kraemer]
232 *) mod_ldap, mod_authnzldap: Add support for nested groups (i.e. the ability
233 to authorize an authenticated user via a "require ldap-group X" directive
234 where the user is not in group X, but is in a subgroup contained in X.
235 PR 42891 [Paul J. Reder]
237 *) mod_ssl: Add support for caching SSL Sessions in memcached. [Paul Querna]
239 *) ab: Add -r option to continue after socket receive errors.
240 [Filip Hanik <devlist hanik.com>]
242 *) mod_ldap: Fix the search limit parameter to ldap_search_ext_s()
243 for SDKs that define LDAP_NO_LIMIT to something other than -1.
244 [David Jones <oscaremma gmail.com>]
246 *) apxs: Enhance -q flag to print all known variables and their values
247 when invoked without variable name(s).
248 [William Rowe, Sander Temme]
250 *) apxs: Eliminate run-time check for mod_so. PR 40653.
251 [David M. Lee <dmlee crossroads.com>]
253 *) beos MPM: Create pmain pool and run modules' child_init hooks when
254 entering ap_mpm_run(), then destroy pmain when exiting ap_mpm_run().
257 *) netware MPM: Destroy pmain pool when exiting ap_mpm_run() so that
258 cleanups registered in modules' child_init hooks are performed.
261 *) mod_dbd: Stash DBD connections in request_config of initial request
262 only, or else sub-requests and internal redirections may cause
263 entire DBD pool to be stashed in a single HTTP request. [Chris Darroch]
265 *) Fix issue which could cause error messages to be written to access logs
266 on Win32. PR 40476. [Tom Donovan <Tom.Donovan acm.org>]
268 *) The LockFile directive, which specifies the location of
269 the accept() mutex lockfile, is deprecated. Instead, the
270 AcceptMutex directive now takes an optional lockfile
271 location parameter, ala SSLMutex. [Jim Jagielski]
273 *) mod_authn_dbd: Export any additional columns queried in the SQL select
274 into the environment with the name AUTHENTICATE_<COLUMN>. This brings
275 mod_authn_dbd behaviour in line with mod_authnz_ldap. [Graham Leggett]
277 *) mod_dbd: Key the storage of prepared statements on the hex string
278 value of server_rec, rather than the server name, as the server name
279 may change (eg when the server name is set) at any time, causing
280 weird behaviour in modules dependent on mod_dbd. [Graham Leggett]
282 *) mod_proxy_fcgi: Added win32 build. [Mladen Turk]
284 *) sendfile_nonblocking() takes the _brigade_ as an argument, gets
285 the first bucket from the brigade, finds it not to be a FILE
286 bucket and barfs. The fix is to pass a bucket rather than a brigade.
287 [Niklas Edmundsson <nikke acc.umu.se>]
289 *) mod_rewrite: support rewritemap by SQL query [Nick Kew]
291 *) ap_get_server_version() has been removed. Third-party modules must
292 now use ap_get_server_banner() or ap_get_server_description().
295 *) All MPMs: Introduce a check_config phase between pre_config and
296 open_logs, to allow modules to review interdependent configuration
297 directive values and adjust them while messages can still be logged
298 to the console. Handle relevant MPM directives during this phase
299 and format messages for both the console and the error log, as
300 appropriate. [Chris Darroch]
302 *) mod_proxy: don't URLencode tilde in path component
303 [Stijn Hoop <stijn sandcat.nl>]
305 *) mpm_winnt: Fix return values from wait_for_many_objects.
306 The return value is index to the signaled thread in the
307 creted_threads array. We can not use WAIT_TIMEOUT because
308 his value is defined as 258, thus limiting the MaxThreads
309 to that value. [Mladen Turk]
311 *) core: Do not allow internal redirects like the DirectoryIndex of mod_dir
312 to circumvent the symbolic link checks imposed by FollowSymLinks and
313 SymLinksIfOwnerMatch. [Nick Kew, Ruediger Pluem, William Rowe]
315 *) mod_proxy: Support environment variable interpolation in reverse
316 proxying directives. [Nick Kew]
318 *) core: Add the filename of the configuration file to the warning message
319 about the useless use of AllowOverride. PR 39992.
320 [Darryl Miles <darryl darrylmiles.org>]
322 *) New SSLLogLevelDebugDump [ None (default) | IO (not bytes) | Bytes ]
323 configures the I/O Dump of SSL traffic, when LogLevel is set to Debug.
324 The default is none as this is far greater debugging resolution than
325 the typical administrator is prepared to untangle. [William Rowe]
327 *) mod_disk_cache: If possible, check if the size of an object to cache is
328 within the configured boundaries before actually saving data.
329 [Niklas Edmundsson <nikke acc.umu.se>]
331 *) mod_cache: Convert all values to seconds before comparing them when
332 checking whether to send a Warning header for a stale response.
333 PR 39713. [Owen Taylor <otaylor redhat.com>]
335 *) mod_disk_cache: Delete temporary files if they cannot be renamed to their
336 final name. [Davi Arnaut <davi haxent.com.br>]
338 *) Worker and event MPMs: Remove improper scoreboard updates which were
339 performed in the event of a fork() failure. [Chris Darroch]
341 *) Add support for fcgi:// proxies to mod_rewrite.
342 [Markus Schiegl <ms schiegl.com>]
344 *) Remove incorrect comments from scoreboard.h regarding conditional
345 loading of worker_score structure with mod_status, and remove unused
346 definitions relating to old life_status field.
347 [Chris Darroch <chrisd pearsoncmg.com>]
349 *) Remove allocation of memory for unused array of lb_score pointers
350 in ap_init_scoreboard(). [Chris Darroch <chrisd pearsoncmg.com>]
352 *) Add mod_proxy_fcgi, a FastCGI back end for mod_proxy.
353 [Garrett Rooney, Jim Jagielski, Paul Querna]
355 *) Event MPM: Fill in the scoreboard's tid field. PR 38736.
356 [Chris Darroch <chrisd pearsoncmg.com>]
358 *) mod_charset_lite: Remove Content-Length when output filter can
359 invalidate it. Warn when input filter can invalidate it.
362 *) Authz: Add the new module mod_authn_core that will provide common
363 authn directives such as 'AuthType', 'AuthName'. Move the directives
364 'AuthType' and 'AuthName' out of the core module and merge mod_authz_alias
365 into mod_authn_core. [Brad Nicholes]
367 *) Authz: Move the directives 'Order', 'Allow', 'Deny' and 'Satisfy'
368 into the new module mod_access_compat which can be loaded to provide
369 support for these directives.
372 *) Authz: Move the 'Require' directive from the core module as well as
373 add the directives '<SatisfyAll>', '<SatisfyOne>', '<RequireAlias>'
374 and 'Reject' to mod_authz_core. The new directives introduce 'AND/OR'
375 logic into the authorization processing. [Brad Nicholes]
377 *) Authz: Add the new module mod_authz_core which acts as the
378 authorization provider vector and contains common authz
379 directives. [Brad Nicholes]
381 *) Authz: Renamed mod_authz_dbm authz providers from 'group' and
382 'file-group' to 'dbm-group' and 'dbm-file-group'. [Brad Nicholes]
384 *) Authz: Added the new authz providers 'env', 'ip', 'host', 'all' to handle
385 host-based access control provided by mod_authz_host and invoked
386 through the 'Require' directive. [Brad Nicholes]
388 *) Authz: Convert all of the authz modules from hook based to
389 provider based. [Brad Nicholes]
391 *) mod_cache: Add CacheMinExpire directive to set the minimum time in
392 seconds to cache a document.
393 [Brian Akins <brian.akins turner.com>, Ruediger Pluem]
395 *) mod_authz_dbd: SQL authz with Login/Session support [Nick Kew]
397 *) Fix typo in ProxyStatus syntax error message.
398 [Christophe Jaillet <christophe.jaillet wanadoo.fr>]
400 *) Asynchronous write completion for the Event MPM. [Brian Pane]
402 *) Added an End-Of-Request bucket type. The logging of a request and
403 the freeing of its pool are now done when the EOR bucket is destroyed.
404 This has the effect of delaying the logging until right after the last
405 of the response is sent; ap_core_output_filter() calls the access logger
406 indirectly when it destroys the EOR bucket. [Brian Pane]
408 *) Rewrite of logresolve support utility: IPv6 addresses are now supported
409 and the format of statistical output has changed. [Colm MacCarthaigh]
411 *) Rewrite of ap_coreoutput_filter to do nonblocking writes [Brian Pane]
413 *) Added new connection states for handler and write completion
416 *) mod_cgid: Refuse to work on Solaris 10 due to OS bugs. PR 34264.
419 *) Teach mod_ssl to use arbitrary OIDs in an SSLRequire directive,
420 allowing string-valued client certificate attributes to be used for
421 access control, as in: SSLRequire "value" in OID("1.3.6.1.4.1.18060.1")
