2 Changes with Apache 2.3.0
3 [ When backported to 2.2.x, remove entry from this file ]
5 *) mod_authnz_ldap: don't return NULL-valued environment variables to
6 other modules. PR 39045 [Francois Pesce <francois.pesce gmail.com>]
8 *) Don't adjust case in pathname components that are not of interest
9 to mod_mime. Fixes mod_negotiation's use of such components.
10 PR 43250 [Basant Kumar Kukreja <basant.kukreja sun.com>]
12 *) Add new LogFormat parameter, %k, which logs the number of
13 keepalive requests on this connection for this request..
14 [Dan Poirier <poirier pobox.com>]
16 *) Be tolerant in what you accept - accept slightly broken
17 status lines from a backend provide they include a valid status code.
18 PR 44995 [Rainer Jung <rainer.jung kippdata.de>]
20 *) New module mod_sed: filter Request/Response bodies through sed
21 [Basant Kumar Kukreja <basant.kukreja sun.com>]
23 *) mod_auth_form: Make sure that basic authentication is correctly
24 faked directly after login. [Graham Leggett]
26 *) mod_session_cookie, mod_session_dbd: Make sure cookies are set both
27 within the output headers and error output headers, so that the
28 session is maintained across redirects. [Graham Leggett]
30 *) mod_auth_form: Make sure the logged in user is populated correctly
31 after a form login. Fixes a missing REMOTE_USER variable directly
32 following a login. [Graham Leggett]
34 *) mod_session_cookie: Make sure that cookie attributes are correctly
35 included in the blank cookie when cookies are removed. This fixes an
36 inability to log out when using mod_auth_form. [Graham Leggett]
38 *) mod_autoindex: add configuration option to insert string
39 in HTML HEAD. [Nick Kew]
41 *) mod_ssl: implement dynamic mutex callbacks for the benefit of
42 OpenSSL. [Sander Temme]
44 *) mod_session: Prevent a segfault when a CGI script sets a cookie with a
45 null value. [David Shane Holden <dpejesh apache.org>]
47 *) mod_headers: Prevent Header edit from processing only the first header
48 of possibly multiple headers with the same name and deleting the
49 remaining ones. PR 45333. [Ruediger Pluem]
51 *) mod_rewrite: Preserve the query string with [proxy,noescape]. PR 45247
54 *) core, authn/z: Determine registered authn/z providers directly in
55 ap_setup_auth_internal(), which allows optional functions that just
56 wrapped ap_list_provider_names() to be removed from authn/z modules.
59 *) authn/z: Convert common provider version strings to macros.
62 *) ab: Make ab.c compile on VC6. PR 45024 [Ruediger Pluem]
64 *) configure: Don't reject libtool 2.x
65 PR 44817 [Arfrever Frehtes Taifersar Arahesis <Arfrever.FTA gmail.com>]
67 *) core: When testing for slash-terminated configuration paths in
68 ap_location_walk(), don't look past the start of an empty string
69 such as that created by a <Location ""> directive.
72 *) core, mod_proxy: If a kept_body is present, it becomes safe for
73 subrequests to support message bodies. Make sure that safety
74 checks within the core and within the proxy are not triggered
75 when kept_body is present. This makes it possible to embed
76 proxied POST requests within mod_include. [Graham Leggett]
78 *) mod_auth_form: Make sure the input filter stack is properly set
79 up before reading the login form. Make sure the kept body filter
80 is correctly inserted to ensure the body can be read a second
81 time safely should the authn be successful. [Graham Leggett,
84 *) mod_request: Insert the KEPT_BODY filter via the insert_filter
85 hook instead of during fixups. Add a safety check to ensure the
86 filters cannot be inserted more than once. [Graham Leggett,
89 *) core: Do not allow Options ALL if not all options are allowed to be
90 overwritten. PR 44262 [Michał Grzędzicki <lazy iq.pl>]
92 *) ap_cache_cacheable_headers_out() will (now) always
93 merge an error heaeders _before_ clearing them and _before_
94 merging in the actual entity headers and doing normal
95 hop-by-hop cleansing. [Dirk-Willem van Gulik].
97 *) cache: retire ap_cache_cacheable_hdrs_out() which was used
98 for both in- and out-put headers; and replace it by a single
99 ap_cache_cacheable_headers() wrapped in a in- and out-put
100 specific ap_cache_cacheable_headers_in()/out(). The latter
101 which will also merge error and ensure content-type. To keep
102 cache modules consistent with ease. This API change bumps
103 up the minor MM by one [Dirk-Willem van Gulik].
105 *) mod_rewrite: Allow Cookie option to set secure and HttpOnly flags.
106 PR 44799 [Christian Wenz <christian wenz.org>]
108 *) Move the KeptBodySize directive, kept_body filters and the
109 ap_parse_request_body function out of the http module and into a
110 new module called mod_request, reducing the size of the core.
113 *) mod_dbd: Handle integer configuration directive parameters with a
116 *) Change the directives within the mod_session* modules to be valid
117 both inside and outside the location/directory sections, as
118 suggested by wrowe. [Graham Leggett]
120 *) mod_auth_form: Add a module capable of allowing end users to log
121 in using an HTML form, storing the credentials within mod_session.
124 *) Add a function to the http filters that is able to parse an HTML
125 form request with the type of application/x-www-form-urlencoded.
128 *) mod_session_crypto: Initialise SSL in the post config hook.
129 [Ruediger Pluem, Graham Leggett]
131 *) mod_session_dbd: Add a session implementation capable of storing
132 session information in a SQL database via the dbd interface. Useful
133 for sites where session privacy is important. [Graham Leggett]
135 *) mod_session_crypto: Add a session encoding implementation capable
136 of encrypting and decrypting sessions wherever they may be stored.
137 Introduces a level of privacy when sessions are stored on the
138 browser. [Graham Leggett]
140 *) mod_session_cookie: Add a session implementation capable of storing
141 session information within cookies on the browser. Useful for high
142 volume sites where server bound sessions are too resource intensive.
145 *) mod_session: Add a generic session interface to unify the different
146 attempts at saving persistent sessions across requests.
149 *) core, authn/z: Avoid calling access control hooks for internal requests
150 with configurations which match those of initial request. Revert to
151 original behaviour (call access control hooks for internal requests
152 with URIs different from initial request) if any access control hooks or
153 providers are not registered as permitting this optimization.
154 Introduce wrappers for access control hook and provider registration
155 which can accept additional mode and flag data. [Chris Darroch]
157 *) Introduced ap_expr API for expression evaluation.
158 This is adapted from mod_include, which is the first module
162 *) mod_authz_dbd: When redirecting after successful login/logout per
163 AuthzDBDRedirectQuery, do not report authorization failure, and use
164 first row returned by database query instead of last row.
167 *) mod_ldap: Correctly return all requested attribute values
168 when some attributes have a null value.
169 PR 44560 [Anders Kaseorg <anders kaseorg.com>]
171 *) core: check symlink ownership if both FollowSymlinks and
172 SymlinksIfOwnerMatch are set [Nick Kew]
174 *) core: fix origin checking in SymlinksIfOwnerMatch
175 PR 36783 [Robert L Mathews <rob-apache.org.bugs tigertech.net>]
177 *) Activate mod_cache, mod_file_cache and mod_disc_cache as part of the
178 'most' set for '--enable-modules' and '--enable-shared-mods'. Include
179 mod_mem_cache in 'all' as well. [Dirk-Willem van Gulik]
181 *) Also install mod_so.h, mod_rewrite.h and mod_cache.h; as these
182 contain public function declarations which are useful for
183 third party module authors. PR 42431 [Dirk-Willem van Gulik].
185 *) mod_dir, mod_negotiation: pass the output filter information
186 to newly created sub requests; as these are later on used
187 as true requests with an internal redirect. This allows for
188 mod_cache et.al. to trap the results of the redirect.
189 [Dirk-Willem van Gulik, Ruediger Pluem]
191 *) mod_ldap: Add support (taking advantage of the new APR capability)
192 for ldap rebind callback while chasing referrals. This allows direct
193 searches on LDAP servers (in particular MS Active Directory 2003+)
194 using referrals without the use of the global catalog.
195 PRs 26538, 40268, and 42557 [Paul J. Reder]
197 *) Support chroot on Unix-family platforms
198 PR 43596 [Dimitar Pashev <mitko banksoft-bg.com>]
200 *) mod_ssl: Added server name indication support (SNI, RFC 4366).
201 PR 34607. [Kaspar Brand <asfbugz velox.ch>]. A test configuration
202 can be created with test/make_sni.sh [Dirk-Willem van Gulik].
204 *) ApacheMonitor.exe: Introduce --kill argument for use by the
205 installer. This will permit the installation tool to remove
206 all running instances before attempting to remove the .exe.
209 *) mod_ssl: Add support for OCSP validation of client certificates.
210 PR 41123. [Marc Stern <marc.stern approach.be>, Joe Orton]
212 *) mod_serf: New module for Reverse Proxying. [Paul Querna]
214 *) core: Add the option to keep aside a request body up to a certain
215 size that would otherwise be discarded, to be consumed by filters
216 such as mod_include. When enabled for a directory, POST requests
217 to shtml files can be passed through to embedded scripts as POST
218 requests, rather being downgraded to GET requests. [Graham Leggett]
220 *) mod_ssl: Fix TLS upgrade (RFC 2817) support. PR 41231. [Joe Orton]
222 *) scoreboard: Correctly declare ap_time_process_request.
223 PR 43789 [Tom Donovan <Tom.Donovan acm.org>]
225 *) core; scoreboard: ap_get_scoreboard_worker(sbh) now takes the sbh member
226 from the connection rec, ap_get_scoreboard_worker(proc, thread) will now
227 provide the unusual legacy lookup. [William Rowe]
229 *) mpm winnt: fix null pointer dereference
230 PR 42572 [Davi Arnaut]
232 *) mod_authnz_ldap, mod_authn_dbd: Tidy up the code to expose authn
233 parameters to the environment. Improve portability to
234 EBCDIC machines by using apr_toupper(). [Martin Kraemer]
236 *) mod_ldap, mod_authnzldap: Add support for nested groups (i.e. the ability
237 to authorize an authenticated user via a "require ldap-group X" directive
238 where the user is not in group X, but is in a subgroup contained in X.
239 PR 42891 [Paul J. Reder]
241 *) mod_ssl: Add support for caching SSL Sessions in memcached. [Paul Querna]
243 *) mod_ldap: Fix the search limit parameter to ldap_search_ext_s()
244 for SDKs that define LDAP_NO_LIMIT to something other than -1.
245 [David Jones <oscaremma gmail.com>]
247 *) apxs: Enhance -q flag to print all known variables and their values
248 when invoked without variable name(s).
249 [William Rowe, Sander Temme]
251 *) apxs: Eliminate run-time check for mod_so. PR 40653.
252 [David M. Lee <dmlee crossroads.com>]
254 *) beos MPM: Create pmain pool and run modules' child_init hooks when
255 entering ap_mpm_run(), then destroy pmain when exiting ap_mpm_run().
258 *) netware MPM: Destroy pmain pool when exiting ap_mpm_run() so that
259 cleanups registered in modules' child_init hooks are performed.
262 *) mod_dbd: Stash DBD connections in request_config of initial request
263 only, or else sub-requests and internal redirections may cause
264 entire DBD pool to be stashed in a single HTTP request. [Chris Darroch]
266 *) Fix issue which could cause error messages to be written to access logs
267 on Win32. PR 40476. [Tom Donovan <Tom.Donovan acm.org>]
269 *) The LockFile directive, which specifies the location of
270 the accept() mutex lockfile, is deprecated. Instead, the
271 AcceptMutex directive now takes an optional lockfile
272 location parameter, ala SSLMutex. [Jim Jagielski]
274 *) mod_authn_dbd: Export any additional columns queried in the SQL select
275 into the environment with the name AUTHENTICATE_<COLUMN>. This brings
276 mod_authn_dbd behaviour in line with mod_authnz_ldap. [Graham Leggett]
278 *) mod_dbd: Key the storage of prepared statements on the hex string
279 value of server_rec, rather than the server name, as the server name
280 may change (eg when the server name is set) at any time, causing
281 weird behaviour in modules dependent on mod_dbd. [Graham Leggett]
283 *) mod_proxy_fcgi: Added win32 build. [Mladen Turk]
285 *) sendfile_nonblocking() takes the _brigade_ as an argument, gets
286 the first bucket from the brigade, finds it not to be a FILE
287 bucket and barfs. The fix is to pass a bucket rather than a brigade.
288 [Niklas Edmundsson <nikke acc.umu.se>]
290 *) mod_rewrite: support rewritemap by SQL query [Nick Kew]
292 *) ap_get_server_version() has been removed. Third-party modules must
293 now use ap_get_server_banner() or ap_get_server_description().
296 *) All MPMs: Introduce a check_config phase between pre_config and
297 open_logs, to allow modules to review interdependent configuration
298 directive values and adjust them while messages can still be logged
299 to the console. Handle relevant MPM directives during this phase
300 and format messages for both the console and the error log, as
301 appropriate. [Chris Darroch]
303 *) mod_proxy: don't URLencode tilde in path component
304 [Stijn Hoop <stijn sandcat.nl>]
306 *) mpm_winnt: Fix return values from wait_for_many_objects.
307 The return value is index to the signaled thread in the
308 creted_threads array. We can not use WAIT_TIMEOUT because
309 his value is defined as 258, thus limiting the MaxThreads
310 to that value. [Mladen Turk]
312 *) core: Do not allow internal redirects like the DirectoryIndex of mod_dir
313 to circumvent the symbolic link checks imposed by FollowSymLinks and
314 SymLinksIfOwnerMatch. [Nick Kew, Ruediger Pluem, William Rowe]
316 *) New SSLLogLevelDebugDump [ None (default) | IO (not bytes) | Bytes ]
317 configures the I/O Dump of SSL traffic, when LogLevel is set to Debug.
318 The default is none as this is far greater debugging resolution than
319 the typical administrator is prepared to untangle. [William Rowe]
321 *) mod_disk_cache: If possible, check if the size of an object to cache is
322 within the configured boundaries before actually saving data.
323 [Niklas Edmundsson <nikke acc.umu.se>]
325 *) mod_cache: Convert all values to seconds before comparing them when
326 checking whether to send a Warning header for a stale response.
327 PR 39713. [Owen Taylor <otaylor redhat.com>]
329 *) mod_disk_cache: Delete temporary files if they cannot be renamed to their
330 final name. [Davi Arnaut <davi haxent.com.br>]
332 *) Worker and event MPMs: Remove improper scoreboard updates which were
333 performed in the event of a fork() failure. [Chris Darroch]
335 *) Add support for fcgi:// proxies to mod_rewrite.
336 [Markus Schiegl <ms schiegl.com>]
338 *) Remove incorrect comments from scoreboard.h regarding conditional
339 loading of worker_score structure with mod_status, and remove unused
340 definitions relating to old life_status field.
341 [Chris Darroch <chrisd pearsoncmg.com>]
343 *) Remove allocation of memory for unused array of lb_score pointers
344 in ap_init_scoreboard(). [Chris Darroch <chrisd pearsoncmg.com>]
346 *) Add mod_proxy_fcgi, a FastCGI back end for mod_proxy.
347 [Garrett Rooney, Jim Jagielski, Paul Querna]
349 *) Event MPM: Fill in the scoreboard's tid field. PR 38736.
350 [Chris Darroch <chrisd pearsoncmg.com>]
352 *) mod_charset_lite: Remove Content-Length when output filter can
353 invalidate it. Warn when input filter can invalidate it.
356 *) Authz: Add the new module mod_authn_core that will provide common
357 authn directives such as 'AuthType', 'AuthName'. Move the directives
358 'AuthType' and 'AuthName' out of the core module and merge mod_authz_alias
359 into mod_authn_core. [Brad Nicholes]
361 *) Authz: Move the directives 'Order', 'Allow', 'Deny' and 'Satisfy'
362 into the new module mod_access_compat which can be loaded to provide
363 support for these directives.
366 *) Authz: Move the 'Require' directive from the core module as well as
367 add the directives '<SatisfyAll>', '<SatisfyOne>', '<RequireAlias>'
368 and 'Reject' to mod_authz_core. The new directives introduce 'AND/OR'
369 logic into the authorization processing. [Brad Nicholes]
371 *) Authz: Add the new module mod_authz_core which acts as the
372 authorization provider vector and contains common authz
373 directives. [Brad Nicholes]
375 *) Authz: Renamed mod_authz_dbm authz providers from 'group' and
376 'file-group' to 'dbm-group' and 'dbm-file-group'. [Brad Nicholes]
378 *) Authz: Added the new authz providers 'env', 'ip', 'host', 'all' to handle
379 host-based access control provided by mod_authz_host and invoked
380 through the 'Require' directive. [Brad Nicholes]
382 *) Authz: Convert all of the authz modules from hook based to
383 provider based. [Brad Nicholes]
385 *) mod_cache: Add CacheMinExpire directive to set the minimum time in
386 seconds to cache a document.
387 [Brian Akins <brian.akins turner.com>, Ruediger Pluem]
389 *) mod_authz_dbd: SQL authz with Login/Session support [Nick Kew]
391 *) Fix typo in ProxyStatus syntax error message.
392 [Christophe Jaillet <christophe.jaillet wanadoo.fr>]
394 *) Asynchronous write completion for the Event MPM. [Brian Pane]
396 *) Added an End-Of-Request bucket type. The logging of a request and
397 the freeing of its pool are now done when the EOR bucket is destroyed.
398 This has the effect of delaying the logging until right after the last
399 of the response is sent; ap_core_output_filter() calls the access logger
400 indirectly when it destroys the EOR bucket. [Brian Pane]
402 *) Rewrite of logresolve support utility: IPv6 addresses are now supported
403 and the format of statistical output has changed. [Colm MacCarthaigh]
405 *) Rewrite of ap_coreoutput_filter to do nonblocking writes [Brian Pane]
407 *) Added new connection states for handler and write completion
410 *) mod_cgid: Refuse to work on Solaris 10 due to OS bugs. PR 34264.
413 *) Teach mod_ssl to use arbitrary OIDs in an SSLRequire directive,
414 allowing string-valued client certificate attributes to be used for
415 access control, as in: SSLRequire "value" in OID("1.3.6.1.4.1.18060.1")
