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