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_dav_fs: Retrieve minimal system information about directory
14 entries when walking a DAV fs, resolving a performance degradation on
15 Windows. PR 45464. [Jeff Trawick]
17 *) mod_cgid: Pass along empty command line arguments from an ISINDEX
18 query that has consecutive '+' characters in the QUERY_STRING,
19 matching the behavior of mod_cgi.
22 *) mod_auth_core: Detect during startup when AuthDigestProvider
23 is configured to use an incompatible provider via AuthnProviderAlias.
24 PR 45196 [Eric Covener]
26 *) mod_session: Prevent a segfault when a CGI script sets a cookie with a
27 null value. [David Shane Holden <dpejesh apache.org>]
29 *) mod_headers: Prevent Header edit from processing only the first header
30 of possibly multiple headers with the same name and deleting the
31 remaining ones. PR 45333. [Ruediger Pluem]
33 *) mod_rewrite: Preserve the query string with [proxy,noescape]. PR 45247
36 *) mod_proxy_http: Do not forward requests with 'Expect: 100-continue' to
37 known HTTP/1.0 servers. Return 'Expectation failed' (417) instead.
40 *) core, authn/z: Determine registered authn/z providers directly in
41 ap_setup_auth_internal(), which allows optional functions that just
42 wrapped ap_list_provider_names() to be removed from authn/z modules.
45 *) authn/z: Convert common provider version strings to macros.
48 *) ab: Make ab.c compile on VC6. PR 45024 [Ruediger Pluem]
50 *) configure: Don't reject libtool 2.x
51 PR 44817 [Arfrever Frehtes Taifersar Arahesis <Arfrever.FTA gmail.com>]
53 *) core: When testing for slash-terminated configuration paths in
54 ap_location_walk(), don't look past the start of an empty string
55 such as that created by a <Location ""> directive.
58 *) core, mod_proxy: If a kept_body is present, it becomes safe for
59 subrequests to support message bodies. Make sure that safety
60 checks within the core and within the proxy are not triggered
61 when kept_body is present. This makes it possible to embed
62 proxied POST requests within mod_include. [Graham Leggett]
64 *) mod_auth_form: Make sure the input filter stack is properly set
65 up before reading the login form. Make sure the kept body filter
66 is correctly inserted to ensure the body can be read a second
67 time safely should the authn be successful. [Graham Leggett,
70 *) mod_request: Insert the KEPT_BODY filter via the insert_filter
71 hook instead of during fixups. Add a safety check to ensure the
72 filters cannot be inserted more than once. [Graham Leggett,
75 *) core: Do not allow Options ALL if not all options are allowed to be
76 overwritten. PR 44262 [Michał Grzędzicki <lazy iq.pl>]
78 *) ap_cache_cacheable_headers_out() will (now) always
79 merge an error heaeders _before_ clearing them and _before_
80 merging in the actual entity headers and doing normal
81 hop-by-hop cleansing. [Dirk-Willem van Gulik].
83 *) cache: retire ap_cache_cacheable_hdrs_out() which was used
84 for both in- and out-put headers; and replace it by a single
85 ap_cache_cacheable_headers() wrapped in a in- and out-put
86 specific ap_cache_cacheable_headers_in()/out(). The latter
87 which will also merge error and ensure content-type. To keep
88 cache modules consistent with ease. This API change bumps
89 up the minor MM by one [Dirk-Willem van Gulik].
91 *) mod_rewrite: Allow Cookie option to set secure and HttpOnly flags.
92 PR 44799 [Christian Wenz <christian wenz.org>]
94 *) Move the KeptBodySize directive, kept_body filters and the
95 ap_parse_request_body function out of the http module and into a
96 new module called mod_request, reducing the size of the core.
99 *) mod_dbd: Handle integer configuration directive parameters with a
102 *) Change the directives within the mod_session* modules to be valid
103 both inside and outside the location/directory sections, as
104 suggested by wrowe. [Graham Leggett]
106 *) mod_auth_form: Add a module capable of allowing end users to log
107 in using an HTML form, storing the credentials within mod_session.
110 *) Add a function to the http filters that is able to parse an HTML
111 form request with the type of application/x-www-form-urlencoded.
114 *) mod_session_crypto: Initialise SSL in the post config hook.
115 [Ruediger Pluem, Graham Leggett]
117 *) mod_session_dbd: Add a session implementation capable of storing
118 session information in a SQL database via the dbd interface. Useful
119 for sites where session privacy is important. [Graham Leggett]
121 *) mod_session_crypto: Add a session encoding implementation capable
122 of encrypting and decrypting sessions wherever they may be stored.
123 Introduces a level of privacy when sessions are stored on the
124 browser. [Graham Leggett]
126 *) mod_session_cookie: Add a session implementation capable of storing
127 session information within cookies on the browser. Useful for high
128 volume sites where server bound sessions are too resource intensive.
131 *) mod_session: Add a generic session interface to unify the different
132 attempts at saving persistent sessions across requests.
135 *) core, authn/z: Avoid calling access control hooks for internal requests
136 with configurations which match those of initial request. Revert to
137 original behaviour (call access control hooks for internal requests
138 with URIs different from initial request) if any access control hooks or
139 providers are not registered as permitting this optimization.
140 Introduce wrappers for access control hook and provider registration
141 which can accept additional mode and flag data. [Chris Darroch]
143 *) Introduced ap_expr API for expression evaluation.
144 This is adapted from mod_include, which is the first module
148 *) mod_authz_dbd: When redirecting after successful login/logout per
149 AuthzDBDRedirectQuery, do not report authorization failure, and use
150 first row returned by database query instead of last row.
153 *) mod_ldap: Correctly return all requested attribute values
154 when some attributes have a null value.
155 PR 44560 [Anders Kaseorg <anders kaseorg.com>]
157 *) core: check symlink ownership if both FollowSymlinks and
158 SymlinksIfOwnerMatch are set [Nick Kew]
160 *) core: fix origin checking in SymlinksIfOwnerMatch
161 PR 36783 [Robert L Mathews <rob-apache.org.bugs tigertech.net>]
163 *) Activate mod_cache, mod_file_cache and mod_disc_cache as part of the
164 'most' set for '--enable-modules' and '--enable-shared-mods'. Include
165 mod_mem_cache in 'all' as well. [Dirk-Willem van Gulik]
167 *) Also install mod_so.h, mod_rewrite.h and mod_cache.h; as these
168 contain public function declarations which are useful for
169 third party module authors. PR 42431 [Dirk-Willem van Gulik].
171 *) mod_dir, mod_negotiation: pass the output filter information
172 to newly created sub requests; as these are later on used
173 as true requests with an internal redirect. This allows for
174 mod_cache et.al. to trap the results of the redirect.
175 [Dirk-Willem van Gulik, Ruediger Pluem]
177 *) mod_ldap: Add support (taking advantage of the new APR capability)
178 for ldap rebind callback while chasing referrals. This allows direct
179 searches on LDAP servers (in particular MS Active Directory 2003+)
180 using referrals without the use of the global catalog.
181 PRs 26538, 40268, and 42557 [Paul J. Reder]
183 *) Support chroot on Unix-family platforms
184 PR 43596 [Dimitar Pashev <mitko banksoft-bg.com>]
186 *) mod_ssl: Added server name indication support (SNI, RFC 4366).
187 PR 34607. [Kaspar Brand <asfbugz velox.ch>]. A test configuration
188 can be created with test/make_sni.sh [Dirk-Willem van Gulik].
190 *) ApacheMonitor.exe: Introduce --kill argument for use by the
191 installer. This will permit the installation tool to remove
192 all running instances before attempting to remove the .exe.
195 *) mod_ssl: Add support for OCSP validation of client certificates.
196 PR 41123. [Marc Stern <marc.stern approach.be>, Joe Orton]
198 *) mod_serf: New module for Reverse Proxying. [Paul Querna]
200 *) core: Add the option to keep aside a request body up to a certain
201 size that would otherwise be discarded, to be consumed by filters
202 such as mod_include. When enabled for a directory, POST requests
203 to shtml files can be passed through to embedded scripts as POST
204 requests, rather being downgraded to GET requests. [Graham Leggett]
206 *) mod_ssl: Fix TLS upgrade (RFC 2817) support. PR 41231. [Joe Orton]
208 *) scoreboard: Correctly declare ap_time_process_request.
209 PR 43789 [Tom Donovan <Tom.Donovan acm.org>]
211 *) core; scoreboard: ap_get_scoreboard_worker(sbh) now takes the sbh member
212 from the connection rec, ap_get_scoreboard_worker(proc, thread) will now
213 provide the unusual legacy lookup. [William Rowe]
215 *) mpm winnt: fix null pointer dereference
216 PR 42572 [Davi Arnaut]
218 *) mod_authnz_ldap, mod_authn_dbd: Tidy up the code to expose authn
219 parameters to the environment. Improve portability to
220 EBCDIC machines by using apr_toupper(). [Martin Kraemer]
222 *) mod_ldap, mod_authnzldap: Add support for nested groups (i.e. the ability
223 to authorize an authenticated user via a "require ldap-group X" directive
224 where the user is not in group X, but is in a subgroup contained in X.
225 PR 42891 [Paul J. Reder]
227 *) mod_ssl: Add support for caching SSL Sessions in memcached. [Paul Querna]
229 *) mod_ldap: Fix the search limit parameter to ldap_search_ext_s()
230 for SDKs that define LDAP_NO_LIMIT to something other than -1.
231 [David Jones <oscaremma gmail.com>]
233 *) apxs: Enhance -q flag to print all known variables and their values
234 when invoked without variable name(s).
235 [William Rowe, Sander Temme]
237 *) apxs: Eliminate run-time check for mod_so. PR 40653.
238 [David M. Lee <dmlee crossroads.com>]
240 *) beos MPM: Create pmain pool and run modules' child_init hooks when
241 entering ap_mpm_run(), then destroy pmain when exiting ap_mpm_run().
244 *) netware MPM: Destroy pmain pool when exiting ap_mpm_run() so that
245 cleanups registered in modules' child_init hooks are performed.
248 *) mod_dbd: Stash DBD connections in request_config of initial request
249 only, or else sub-requests and internal redirections may cause
250 entire DBD pool to be stashed in a single HTTP request. [Chris Darroch]
252 *) Fix issue which could cause error messages to be written to access logs
253 on Win32. PR 40476. [Tom Donovan <Tom.Donovan acm.org>]
255 *) The LockFile directive, which specifies the location of
256 the accept() mutex lockfile, is deprecated. Instead, the
257 AcceptMutex directive now takes an optional lockfile
258 location parameter, ala SSLMutex. [Jim Jagielski]
260 *) mod_authn_dbd: Export any additional columns queried in the SQL select
261 into the environment with the name AUTHENTICATE_<COLUMN>. This brings
262 mod_authn_dbd behaviour in line with mod_authnz_ldap. [Graham Leggett]
264 *) mod_dbd: Key the storage of prepared statements on the hex string
265 value of server_rec, rather than the server name, as the server name
266 may change (eg when the server name is set) at any time, causing
267 weird behaviour in modules dependent on mod_dbd. [Graham Leggett]
269 *) mod_proxy_fcgi: Added win32 build. [Mladen Turk]
271 *) sendfile_nonblocking() takes the _brigade_ as an argument, gets
272 the first bucket from the brigade, finds it not to be a FILE
273 bucket and barfs. The fix is to pass a bucket rather than a brigade.
274 [Niklas Edmundsson <nikke acc.umu.se>]
276 *) mod_rewrite: support rewritemap by SQL query [Nick Kew]
278 *) ap_get_server_version() has been removed. Third-party modules must
279 now use ap_get_server_banner() or ap_get_server_description().
282 *) All MPMs: Introduce a check_config phase between pre_config and
283 open_logs, to allow modules to review interdependent configuration
284 directive values and adjust them while messages can still be logged
285 to the console. Handle relevant MPM directives during this phase
286 and format messages for both the console and the error log, as
287 appropriate. [Chris Darroch]
289 *) mod_proxy: don't URLencode tilde in path component
290 [Stijn Hoop <stijn sandcat.nl>]
292 *) mpm_winnt: Fix return values from wait_for_many_objects.
293 The return value is index to the signaled thread in the
294 creted_threads array. We can not use WAIT_TIMEOUT because
295 his value is defined as 258, thus limiting the MaxThreads
296 to that value. [Mladen Turk]
298 *) core: Do not allow internal redirects like the DirectoryIndex of mod_dir
299 to circumvent the symbolic link checks imposed by FollowSymLinks and
300 SymLinksIfOwnerMatch. [Nick Kew, Ruediger Pluem, William Rowe]
302 *) New SSLLogLevelDebugDump [ None (default) | IO (not bytes) | Bytes ]
303 configures the I/O Dump of SSL traffic, when LogLevel is set to Debug.
304 The default is none as this is far greater debugging resolution than
305 the typical administrator is prepared to untangle. [William Rowe]
307 *) mod_disk_cache: If possible, check if the size of an object to cache is
308 within the configured boundaries before actually saving data.
309 [Niklas Edmundsson <nikke acc.umu.se>]
311 *) mod_cache: Convert all values to seconds before comparing them when
312 checking whether to send a Warning header for a stale response.
313 PR 39713. [Owen Taylor <otaylor redhat.com>]
315 *) mod_disk_cache: Delete temporary files if they cannot be renamed to their
316 final name. [Davi Arnaut <davi haxent.com.br>]
318 *) Worker and event MPMs: Remove improper scoreboard updates which were
319 performed in the event of a fork() failure. [Chris Darroch]
321 *) Add support for fcgi:// proxies to mod_rewrite.
322 [Markus Schiegl <ms schiegl.com>]
324 *) Remove incorrect comments from scoreboard.h regarding conditional
325 loading of worker_score structure with mod_status, and remove unused
326 definitions relating to old life_status field.
327 [Chris Darroch <chrisd pearsoncmg.com>]
329 *) Remove allocation of memory for unused array of lb_score pointers
330 in ap_init_scoreboard(). [Chris Darroch <chrisd pearsoncmg.com>]
332 *) Add mod_proxy_fcgi, a FastCGI back end for mod_proxy.
333 [Garrett Rooney, Jim Jagielski, Paul Querna]
335 *) Event MPM: Fill in the scoreboard's tid field. PR 38736.
336 [Chris Darroch <chrisd pearsoncmg.com>]
338 *) mod_charset_lite: Remove Content-Length when output filter can
339 invalidate it. Warn when input filter can invalidate it.
342 *) Authz: Add the new module mod_authn_core that will provide common
343 authn directives such as 'AuthType', 'AuthName'. Move the directives
344 'AuthType' and 'AuthName' out of the core module and merge mod_authz_alias
345 into mod_authn_core. [Brad Nicholes]
347 *) Authz: Move the directives 'Order', 'Allow', 'Deny' and 'Satisfy'
348 into the new module mod_access_compat which can be loaded to provide
349 support for these directives.
352 *) Authz: Move the 'Require' directive from the core module as well as
353 add the directives '<SatisfyAll>', '<SatisfyOne>', '<RequireAlias>'
354 and 'Reject' to mod_authz_core. The new directives introduce 'AND/OR'
355 logic into the authorization processing. [Brad Nicholes]
357 *) Authz: Add the new module mod_authz_core which acts as the
358 authorization provider vector and contains common authz
359 directives. [Brad Nicholes]
361 *) Authz: Renamed mod_authz_dbm authz providers from 'group' and
362 'file-group' to 'dbm-group' and 'dbm-file-group'. [Brad Nicholes]
364 *) Authz: Added the new authz providers 'env', 'ip', 'host', 'all' to handle
365 host-based access control provided by mod_authz_host and invoked
366 through the 'Require' directive. [Brad Nicholes]
368 *) Authz: Convert all of the authz modules from hook based to
369 provider based. [Brad Nicholes]
371 *) mod_cache: Add CacheMinExpire directive to set the minimum time in
372 seconds to cache a document.
373 [Brian Akins <brian.akins turner.com>, Ruediger Pluem]
375 *) mod_authz_dbd: SQL authz with Login/Session support [Nick Kew]
377 *) Fix typo in ProxyStatus syntax error message.
378 [Christophe Jaillet <christophe.jaillet wanadoo.fr>]
380 *) Asynchronous write completion for the Event MPM. [Brian Pane]
382 *) Added an End-Of-Request bucket type. The logging of a request and
383 the freeing of its pool are now done when the EOR bucket is destroyed.
384 This has the effect of delaying the logging until right after the last
385 of the response is sent; ap_core_output_filter() calls the access logger
386 indirectly when it destroys the EOR bucket. [Brian Pane]
388 *) Rewrite of logresolve support utility: IPv6 addresses are now supported
389 and the format of statistical output has changed. [Colm MacCarthaigh]
391 *) Rewrite of ap_coreoutput_filter to do nonblocking writes [Brian Pane]
393 *) Added new connection states for handler and write completion
396 *) mod_cgid: Refuse to work on Solaris 10 due to OS bugs. PR 34264.
399 *) Teach mod_ssl to use arbitrary OIDs in an SSLRequire directive,
400 allowing string-valued client certificate attributes to be used for
401 access control, as in: SSLRequire "value" in OID("1.3.6.1.4.1.18060.1")
