2 Changes with Apache 2.3.0
3 [ When backported to 2.2.x, remove entry from this file ]
5 *) mod_proxy_http: Introduce environment variable proxy-initial-not-pooled to
6 avoid reusing pooled connections if the client connection is an initial
7 connection. PR 37770. [Ruediger Pluem]
9 *) mod_proxy: Add connectiontimeout parameter for proxy workers in order to
10 be able to set the timeout for connecting to the backend separately.
11 PR 45445. [Ruediger Pluem, rahul <rahul sun.com>]
13 *) mod_auth_core: Detect during startup when AuthDigestProvider
14 is configured to use an incompatible provider via AuthnProviderAlias.
15 PR 45196 [Eric Covener]
17 *) mod_session: Prevent a segfault when a CGI script sets a cookie with a
18 null value. [David Shane Holden <dpejesh apache.org>]
20 *) mod_headers: Prevent Header edit from processing only the first header
21 of possibly multiple headers with the same name and deleting the
22 remaining ones. PR 45333. [Ruediger Pluem]
24 *) mod_rewrite: Preserve the query string with [proxy,noescape]. PR 45247
27 *) core, authn/z: Determine registered authn/z providers directly in
28 ap_setup_auth_internal(), which allows optional functions that just
29 wrapped ap_list_provider_names() to be removed from authn/z modules.
32 *) authn/z: Convert common provider version strings to macros.
35 *) ab: Make ab.c compile on VC6. PR 45024 [Ruediger Pluem]
37 *) configure: Don't reject libtool 2.x
38 PR 44817 [Arfrever Frehtes Taifersar Arahesis <Arfrever.FTA gmail.com>]
40 *) core: When testing for slash-terminated configuration paths in
41 ap_location_walk(), don't look past the start of an empty string
42 such as that created by a <Location ""> directive.
45 *) core, mod_proxy: If a kept_body is present, it becomes safe for
46 subrequests to support message bodies. Make sure that safety
47 checks within the core and within the proxy are not triggered
48 when kept_body is present. This makes it possible to embed
49 proxied POST requests within mod_include. [Graham Leggett]
51 *) mod_auth_form: Make sure the input filter stack is properly set
52 up before reading the login form. Make sure the kept body filter
53 is correctly inserted to ensure the body can be read a second
54 time safely should the authn be successful. [Graham Leggett,
57 *) mod_request: Insert the KEPT_BODY filter via the insert_filter
58 hook instead of during fixups. Add a safety check to ensure the
59 filters cannot be inserted more than once. [Graham Leggett,
62 *) core: Do not allow Options ALL if not all options are allowed to be
63 overwritten. PR 44262 [Michał Grzędzicki <lazy iq.pl>]
65 *) ap_cache_cacheable_headers_out() will (now) always
66 merge an error heaeders _before_ clearing them and _before_
67 merging in the actual entity headers and doing normal
68 hop-by-hop cleansing. [Dirk-Willem van Gulik].
70 *) cache: retire ap_cache_cacheable_hdrs_out() which was used
71 for both in- and out-put headers; and replace it by a single
72 ap_cache_cacheable_headers() wrapped in a in- and out-put
73 specific ap_cache_cacheable_headers_in()/out(). The latter
74 which will also merge error and ensure content-type. To keep
75 cache modules consistent with ease. This API change bumps
76 up the minor MM by one [Dirk-Willem van Gulik].
78 *) mod_rewrite: Allow Cookie option to set secure and HttpOnly flags.
79 PR 44799 [Christian Wenz <christian wenz.org>]
81 *) Move the KeptBodySize directive, kept_body filters and the
82 ap_parse_request_body function out of the http module and into a
83 new module called mod_request, reducing the size of the core.
86 *) mod_dbd: Handle integer configuration directive parameters with a
89 *) Change the directives within the mod_session* modules to be valid
90 both inside and outside the location/directory sections, as
91 suggested by wrowe. [Graham Leggett]
93 *) mod_auth_form: Add a module capable of allowing end users to log
94 in using an HTML form, storing the credentials within mod_session.
97 *) Add a function to the http filters that is able to parse an HTML
98 form request with the type of application/x-www-form-urlencoded.
101 *) mod_session_crypto: Initialise SSL in the post config hook.
102 [Ruediger Pluem, Graham Leggett]
104 *) mod_session_dbd: Add a session implementation capable of storing
105 session information in a SQL database via the dbd interface. Useful
106 for sites where session privacy is important. [Graham Leggett]
108 *) mod_session_crypto: Add a session encoding implementation capable
109 of encrypting and decrypting sessions wherever they may be stored.
110 Introduces a level of privacy when sessions are stored on the
111 browser. [Graham Leggett]
113 *) mod_session_cookie: Add a session implementation capable of storing
114 session information within cookies on the browser. Useful for high
115 volume sites where server bound sessions are too resource intensive.
118 *) mod_session: Add a generic session interface to unify the different
119 attempts at saving persistent sessions across requests.
122 *) core, authn/z: Avoid calling access control hooks for internal requests
123 with configurations which match those of initial request. Revert to
124 original behaviour (call access control hooks for internal requests
125 with URIs different from initial request) if any access control hooks or
126 providers are not registered as permitting this optimization.
127 Introduce wrappers for access control hook and provider registration
128 which can accept additional mode and flag data. [Chris Darroch]
130 *) Introduced ap_expr API for expression evaluation.
131 This is adapted from mod_include, which is the first module
135 *) mod_authz_dbd: When redirecting after successful login/logout per
136 AuthzDBDRedirectQuery, do not report authorization failure, and use
137 first row returned by database query instead of last row.
140 *) mod_ldap: Correctly return all requested attribute values
141 when some attributes have a null value.
142 PR 44560 [Anders Kaseorg <anders kaseorg.com>]
144 *) core: check symlink ownership if both FollowSymlinks and
145 SymlinksIfOwnerMatch are set [Nick Kew]
147 *) core: fix origin checking in SymlinksIfOwnerMatch
148 PR 36783 [Robert L Mathews <rob-apache.org.bugs tigertech.net>]
150 *) Activate mod_cache, mod_file_cache and mod_disc_cache as part of the
151 'most' set for '--enable-modules' and '--enable-shared-mods'. Include
152 mod_mem_cache in 'all' as well. [Dirk-Willem van Gulik]
154 *) Also install mod_so.h, mod_rewrite.h and mod_cache.h; as these
155 contain public function declarations which are useful for
156 third party module authors. PR 42431 [Dirk-Willem van Gulik].
158 *) mod_dir, mod_negotiation: pass the output filter information
159 to newly created sub requests; as these are later on used
160 as true requests with an internal redirect. This allows for
161 mod_cache et.al. to trap the results of the redirect.
162 [Dirk-Willem van Gulik, Ruediger Pluem]
164 *) mod_ldap: Add support (taking advantage of the new APR capability)
165 for ldap rebind callback while chasing referrals. This allows direct
166 searches on LDAP servers (in particular MS Active Directory 2003+)
167 using referrals without the use of the global catalog.
168 PRs 26538, 40268, and 42557 [Paul J. Reder]
170 *) Support chroot on Unix-family platforms
171 PR 43596 [Dimitar Pashev <mitko banksoft-bg.com>]
173 *) mod_ssl: Added server name indication support (SNI, RFC 4366).
174 PR 34607. [Kaspar Brand <asfbugz velox.ch>]. A test configuration
175 can be created with test/make_sni.sh [Dirk-Willem van Gulik].
177 *) ApacheMonitor.exe: Introduce --kill argument for use by the
178 installer. This will permit the installation tool to remove
179 all running instances before attempting to remove the .exe.
182 *) mod_ssl: Add support for OCSP validation of client certificates.
183 PR 41123. [Marc Stern <marc.stern approach.be>, Joe Orton]
185 *) mod_serf: New module for Reverse Proxying. [Paul Querna]
187 *) core: Add the option to keep aside a request body up to a certain
188 size that would otherwise be discarded, to be consumed by filters
189 such as mod_include. When enabled for a directory, POST requests
190 to shtml files can be passed through to embedded scripts as POST
191 requests, rather being downgraded to GET requests. [Graham Leggett]
193 *) mod_ssl: Fix TLS upgrade (RFC 2817) support. PR 41231. [Joe Orton]
195 *) scoreboard: Correctly declare ap_time_process_request.
196 PR 43789 [Tom Donovan <Tom.Donovan acm.org>]
198 *) core; scoreboard: ap_get_scoreboard_worker(sbh) now takes the sbh member
199 from the connection rec, ap_get_scoreboard_worker(proc, thread) will now
200 provide the unusual legacy lookup. [William Rowe]
202 *) mpm winnt: fix null pointer dereference
203 PR 42572 [Davi Arnaut]
205 *) mod_authnz_ldap, mod_authn_dbd: Tidy up the code to expose authn
206 parameters to the environment. Improve portability to
207 EBCDIC machines by using apr_toupper(). [Martin Kraemer]
209 *) mod_ldap, mod_authnzldap: Add support for nested groups (i.e. the ability
210 to authorize an authenticated user via a "require ldap-group X" directive
211 where the user is not in group X, but is in a subgroup contained in X.
212 PR 42891 [Paul J. Reder]
214 *) mod_ssl: Add support for caching SSL Sessions in memcached. [Paul Querna]
216 *) mod_ldap: Fix the search limit parameter to ldap_search_ext_s()
217 for SDKs that define LDAP_NO_LIMIT to something other than -1.
218 [David Jones <oscaremma gmail.com>]
220 *) apxs: Enhance -q flag to print all known variables and their values
221 when invoked without variable name(s).
222 [William Rowe, Sander Temme]
224 *) apxs: Eliminate run-time check for mod_so. PR 40653.
225 [David M. Lee <dmlee crossroads.com>]
227 *) beos MPM: Create pmain pool and run modules' child_init hooks when
228 entering ap_mpm_run(), then destroy pmain when exiting ap_mpm_run().
231 *) netware MPM: Destroy pmain pool when exiting ap_mpm_run() so that
232 cleanups registered in modules' child_init hooks are performed.
235 *) mod_dbd: Stash DBD connections in request_config of initial request
236 only, or else sub-requests and internal redirections may cause
237 entire DBD pool to be stashed in a single HTTP request. [Chris Darroch]
239 *) Fix issue which could cause error messages to be written to access logs
240 on Win32. PR 40476. [Tom Donovan <Tom.Donovan acm.org>]
242 *) The LockFile directive, which specifies the location of
243 the accept() mutex lockfile, is deprecated. Instead, the
244 AcceptMutex directive now takes an optional lockfile
245 location parameter, ala SSLMutex. [Jim Jagielski]
247 *) mod_authn_dbd: Export any additional columns queried in the SQL select
248 into the environment with the name AUTHENTICATE_<COLUMN>. This brings
249 mod_authn_dbd behaviour in line with mod_authnz_ldap. [Graham Leggett]
251 *) mod_dbd: Key the storage of prepared statements on the hex string
252 value of server_rec, rather than the server name, as the server name
253 may change (eg when the server name is set) at any time, causing
254 weird behaviour in modules dependent on mod_dbd. [Graham Leggett]
256 *) mod_proxy_fcgi: Added win32 build. [Mladen Turk]
258 *) sendfile_nonblocking() takes the _brigade_ as an argument, gets
259 the first bucket from the brigade, finds it not to be a FILE
260 bucket and barfs. The fix is to pass a bucket rather than a brigade.
261 [Niklas Edmundsson <nikke acc.umu.se>]
263 *) mod_rewrite: support rewritemap by SQL query [Nick Kew]
265 *) ap_get_server_version() has been removed. Third-party modules must
266 now use ap_get_server_banner() or ap_get_server_description().
269 *) All MPMs: Introduce a check_config phase between pre_config and
270 open_logs, to allow modules to review interdependent configuration
271 directive values and adjust them while messages can still be logged
272 to the console. Handle relevant MPM directives during this phase
273 and format messages for both the console and the error log, as
274 appropriate. [Chris Darroch]
276 *) mod_proxy: don't URLencode tilde in path component
277 [Stijn Hoop <stijn sandcat.nl>]
279 *) mpm_winnt: Fix return values from wait_for_many_objects.
280 The return value is index to the signaled thread in the
281 creted_threads array. We can not use WAIT_TIMEOUT because
282 his value is defined as 258, thus limiting the MaxThreads
283 to that value. [Mladen Turk]
285 *) core: Do not allow internal redirects like the DirectoryIndex of mod_dir
286 to circumvent the symbolic link checks imposed by FollowSymLinks and
287 SymLinksIfOwnerMatch. [Nick Kew, Ruediger Pluem, William Rowe]
289 *) New SSLLogLevelDebugDump [ None (default) | IO (not bytes) | Bytes ]
290 configures the I/O Dump of SSL traffic, when LogLevel is set to Debug.
291 The default is none as this is far greater debugging resolution than
292 the typical administrator is prepared to untangle. [William Rowe]
294 *) mod_disk_cache: If possible, check if the size of an object to cache is
295 within the configured boundaries before actually saving data.
296 [Niklas Edmundsson <nikke acc.umu.se>]
298 *) mod_cache: Convert all values to seconds before comparing them when
299 checking whether to send a Warning header for a stale response.
300 PR 39713. [Owen Taylor <otaylor redhat.com>]
302 *) mod_disk_cache: Delete temporary files if they cannot be renamed to their
303 final name. [Davi Arnaut <davi haxent.com.br>]
305 *) Worker and event MPMs: Remove improper scoreboard updates which were
306 performed in the event of a fork() failure. [Chris Darroch]
308 *) Add support for fcgi:// proxies to mod_rewrite.
309 [Markus Schiegl <ms schiegl.com>]
311 *) Remove incorrect comments from scoreboard.h regarding conditional
312 loading of worker_score structure with mod_status, and remove unused
313 definitions relating to old life_status field.
314 [Chris Darroch <chrisd pearsoncmg.com>]
316 *) Remove allocation of memory for unused array of lb_score pointers
317 in ap_init_scoreboard(). [Chris Darroch <chrisd pearsoncmg.com>]
319 *) Add mod_proxy_fcgi, a FastCGI back end for mod_proxy.
320 [Garrett Rooney, Jim Jagielski, Paul Querna]
322 *) Event MPM: Fill in the scoreboard's tid field. PR 38736.
323 [Chris Darroch <chrisd pearsoncmg.com>]
325 *) mod_charset_lite: Remove Content-Length when output filter can
326 invalidate it. Warn when input filter can invalidate it.
329 *) Authz: Add the new module mod_authn_core that will provide common
330 authn directives such as 'AuthType', 'AuthName'. Move the directives
331 'AuthType' and 'AuthName' out of the core module and merge mod_authz_alias
332 into mod_authn_core. [Brad Nicholes]
334 *) Authz: Move the directives 'Order', 'Allow', 'Deny' and 'Satisfy'
335 into the new module mod_access_compat which can be loaded to provide
336 support for these directives.
339 *) Authz: Move the 'Require' directive from the core module as well as
340 add the directives '<SatisfyAll>', '<SatisfyOne>', '<RequireAlias>'
341 and 'Reject' to mod_authz_core. The new directives introduce 'AND/OR'
342 logic into the authorization processing. [Brad Nicholes]
344 *) Authz: Add the new module mod_authz_core which acts as the
345 authorization provider vector and contains common authz
346 directives. [Brad Nicholes]
348 *) Authz: Renamed mod_authz_dbm authz providers from 'group' and
349 'file-group' to 'dbm-group' and 'dbm-file-group'. [Brad Nicholes]
351 *) Authz: Added the new authz providers 'env', 'ip', 'host', 'all' to handle
352 host-based access control provided by mod_authz_host and invoked
353 through the 'Require' directive. [Brad Nicholes]
355 *) Authz: Convert all of the authz modules from hook based to
356 provider based. [Brad Nicholes]
358 *) mod_cache: Add CacheMinExpire directive to set the minimum time in
359 seconds to cache a document.
360 [Brian Akins <brian.akins turner.com>, Ruediger Pluem]
362 *) mod_authz_dbd: SQL authz with Login/Session support [Nick Kew]
364 *) Fix typo in ProxyStatus syntax error message.
365 [Christophe Jaillet <christophe.jaillet wanadoo.fr>]
367 *) Asynchronous write completion for the Event MPM. [Brian Pane]
369 *) Added an End-Of-Request bucket type. The logging of a request and
370 the freeing of its pool are now done when the EOR bucket is destroyed.
371 This has the effect of delaying the logging until right after the last
372 of the response is sent; ap_core_output_filter() calls the access logger
373 indirectly when it destroys the EOR bucket. [Brian Pane]
375 *) Rewrite of logresolve support utility: IPv6 addresses are now supported
376 and the format of statistical output has changed. [Colm MacCarthaigh]
378 *) Rewrite of ap_coreoutput_filter to do nonblocking writes [Brian Pane]
380 *) Added new connection states for handler and write completion
383 *) mod_cgid: Refuse to work on Solaris 10 due to OS bugs. PR 34264.
386 *) Teach mod_ssl to use arbitrary OIDs in an SSLRequire directive,
387 allowing string-valued client certificate attributes to be used for
388 access control, as in: SSLRequire "value" in OID("1.3.6.1.4.1.18060.1")
