2 Changes with Apache 2.3.0
3 [ When backported to 2.2.x, remove entry from this file ]
5 *) mod_substitute: The default is now flattening the buckets after
6 each substitution. This was mostly done to abide by the
7 Principle Of Least Astonishment. The newly added 'q' flag allows for
8 the quicker, more efficient bucket-splitting if the user so
9 desires. [Jim Jagielski]
11 *) Added 'disablereuse' option for ProxyPass which, essentially,
12 disables connection pooling for the backend servers.
15 *) Activate mod_cache, mod_file_cache and mod_disc_cache as part of the
16 'most' set for '--enable-modules' and '--enable-shared-mods'. Include
17 mod_mem_cache in 'all' as well. [Dirk-Willem van Gulik]
19 *) Also install mod_so.h, mod_rewrite.h and mod_cache.h; as these
20 contain public function declarations which are useful for
21 third party module authors. PR 42431 [Dirk-Willem van Gulik].
23 *) mod_dir, mod_negotiation: pass the output filter information
24 to newly created sub requests; as these are later on used
25 as true requests with an internal redirect. This allows for
26 mod_cache et.al. to trap the results of the redirect.
27 [Dirk-Willem van Gulik, Ruediger Pluem]
29 *) ab: Use a 64 bit unsigned int instead of a signed long to count the
30 bytes transferred to avoid integer overflows. PR 44346 [Ruediger Pluem]
32 *) mod_proxy_ajp: Do not retry request in the case that we either failed to
33 sent a part of the request body or if the request is not idempotent.
34 PR 44334 [Ruediger Pluem]
36 *) ProxyPassReverse is now balancer aware. [Jim Jagielski]
38 *) rotatelogs: Don't leak memory when reopening the logfile.
39 PR 40183 [Ruediger Pluem, Takashi Sato <serai lans-tv.com>]
41 *) mod_ldap: Add support (taking advantage of the new APR capability)
42 for ldap rebind callback while chasing referrals. This allows direct
43 searches on LDAP servers (in particular MS Active Directory 2003+)
44 using referrals without the use of the global catalog.
45 PRs 26538, 40268, and 42557 [Paul J. Reder]
47 *) ab: Do not try to read non existing response bodies of HEAD requests.
48 PR 34275 [Takashi Sato <serai lans-tv.com>]
50 *) Support chroot on Unix-family platforms
51 PR 43596 [Dimitar Pashev <mitko banksoft-bg.com>]
53 *) Don't add bogus duplicate Content-Language entries
54 PR 11035 [Davi Arnaut]
56 *) mod_proxy_ftp: Fix base for directory listings.
59 *) mod_proxy_http: Return HTTP status codes instead of apr_status_t
60 values for errors encountered while forwarding the request body
61 PR 44165 [Eric Covener]
63 *) mod_logio: Provide optional function to allow modules to adjust the
64 bytes_in count [Eric Covener]
66 *) mod_ssl: Added server name indication support (SNI, RFC 4366).
67 PR 34607. [Kaspar Brand <asfbugz velox.ch>]. A test configuration
68 can be created with test/make_sni.sh [Dirk-Willem van Gulik].
70 *) ApacheMonitor.exe: Introduce --kill argument for use by the
71 installer. This will permit the installation tool to remove
72 all running instances before attempting to remove the .exe.
75 *) mod_proxy: Lower memory consumption for short lived connections.
76 PR 44026. [Ruediger Pluem]
78 *) mod_proxy: Keep connections to the backend persistent in the HTTPS case.
81 *) rotatelogs: Improve atomicity when using -l and cleaup code.
82 PR 44004 [Rainer Jung]
84 *) mod_ssl: Add support for OCSP validation of client certificates.
85 PR 41123. [Marc Stern <marc.stern approach.be>, Joe Orton]
87 *) mod_unique_id: Fix timestamp value in UNIQUE_ID.
88 PR 37064 [Kobayashi <kobayashi firstserver.co.jp>]
90 *) mod_serf: New module for Reverse Proxying. [Paul Querna]
92 *) core: Add the option to keep aside a request body up to a certain
93 size that would otherwise be discarded, to be consumed by filters
94 such as mod_include. When enabled for a directory, POST requests
95 to shtml files can be passed through to embedded scripts as POST
96 requests, rather being downgraded to GET requests. [Graham Leggett]
98 *) mod_ssl: Fix TLS upgrade (RFC 2817) support. PR 41231. [Joe Orton]
100 *) scoreboard: Correctly declare ap_time_process_request.
101 PR 43789 [Tom Donovan <Tom.Donovan acm.org>]
103 *) core; scoreboard: ap_get_scoreboard_worker(sbh) now takes the sbh member
104 from the connection rec, ap_get_scoreboard_worker(proc, thread) will now
105 provide the unusual legacy lookup. [William Rowe]
107 *) mpm winnt: fix null pointer dereference
108 PR 42572 [Davi Arnaut]
110 *) core: reinstate location walk to fix config for subrequests
111 PR 41960 [Jose Kahan <jose w3.org>]
113 *) mod_log_config: Add format options for %p so that the actual local
114 or remote port can be logged. PR 43415. [Adam Hasselbalch Hansen
115 <ahh@one.com>, Ruediger Pluem, Jeff Trawick]
117 *) mod_authnz_ldap, mod_authn_dbd: Tidy up the code to expose authn
118 parameters to the environment. Improve portability to
119 EBCDIC machines by using apr_toupper(). [Martin Kraemer]
121 *) mod_ldap, mod_authnzldap: Add support for nested groups (i.e. the ability
122 to authorize an authenticated user via a "require ldap-group X" directive
123 where the user is not in group X, but is in a subgroup contained in X.
124 PR 42891 [Paul J. Reder]
126 *) mod_ssl: Add support for caching SSL Sessions in memcached. [Paul Querna]
128 *) ab: Add -r option to continue after socket receive errors.
129 [Filip Hanik <devlist hanik.com>]
131 *) mod_ldap: Fix the search limit parameter to ldap_search_ext_s()
132 for SDKs that define LDAP_NO_LIMIT to something other than -1.
133 [David Jones <oscaremma gmail.com>]
135 *) apxs: Enhance -q flag to print all known variables and their values
136 when invoked without variable name(s).
137 [William Rowe, Sander Temme]
139 *) apxs: Eliminate run-time check for mod_so. PR 40653.
140 [David M. Lee <dmlee crossroads.com>]
142 *) beos MPM: Create pmain pool and run modules' child_init hooks when
143 entering ap_mpm_run(), then destroy pmain when exiting ap_mpm_run().
146 *) netware MPM: Destroy pmain pool when exiting ap_mpm_run() so that
147 cleanups registered in modules' child_init hooks are performed.
150 *) mod_dbd: Stash DBD connections in request_config of initial request
151 only, or else sub-requests and internal redirections may cause
152 entire DBD pool to be stashed in a single HTTP request. [Chris Darroch]
154 *) Fix issue which could cause error messages to be written to access logs
155 on Win32. PR 40476. [Tom Donovan <Tom.Donovan acm.org>]
157 *) The LockFile directive, which specifies the location of
158 the accept() mutex lockfile, is deprecated. Instead, the
159 AcceptMutex directive now takes an optional lockfile
160 location parameter, ala SSLMutex. [Jim Jagielski]
162 *) mod_authn_dbd: Export any additional columns queried in the SQL select
163 into the environment with the name AUTHENTICATE_<COLUMN>. This brings
164 mod_authn_dbd behaviour in line with mod_authnz_ldap. [Graham Leggett]
166 *) mod_dbd: Key the storage of prepared statements on the hex string
167 value of server_rec, rather than the server name, as the server name
168 may change (eg when the server name is set) at any time, causing
169 weird behaviour in modules dependent on mod_dbd. [Graham Leggett]
171 *) mod_proxy_fcgi: Added win32 build. [Mladen Turk]
173 *) sendfile_nonblocking() takes the _brigade_ as an argument, gets
174 the first bucket from the brigade, finds it not to be a FILE
175 bucket and barfs. The fix is to pass a bucket rather than a brigade.
176 [Niklas Edmundsson <nikke acc.umu.se>]
178 *) mod_rewrite: support rewritemap by SQL query [Nick Kew]
180 *) ap_get_server_version() has been removed. Third-party modules must
181 now use ap_get_server_banner() or ap_get_server_description().
184 *) All MPMs: Introduce a check_config phase between pre_config and
185 open_logs, to allow modules to review interdependent configuration
186 directive values and adjust them while messages can still be logged
187 to the console. Handle relevant MPM directives during this phase
188 and format messages for both the console and the error log, as
189 appropriate. [Chris Darroch]
191 *) mod_proxy: don't URLencode tilde in path component
192 [Stijn Hoop <stijn sandcat.nl>]
194 *) mpm_winnt: Fix return values from wait_for_many_objects.
195 The return value is index to the signaled thread in the
196 creted_threads array. We can not use WAIT_TIMEOUT because
197 his value is defined as 258, thus limiting the MaxThreads
198 to that value. [Mladen Turk]
200 *) core: Do not allow internal redirects like the DirectoryIndex of mod_dir
201 to circumvent the symbolic link checks imposed by FollowSymLinks and
202 SymLinksIfOwnerMatch. [Nick Kew, Ruediger Pluem, William Rowe]
204 *) mod_proxy: Support environment variable interpolation in reverse
205 proxying directives. [Nick Kew]
207 *) core: Add the filename of the configuration file to the warning message
208 about the useless use of AllowOverride. PR 39992.
209 [Darryl Miles <darryl darrylmiles.org>]
211 *) New SSLLogLevelDebugDump [ None (default) | IO (not bytes) | Bytes ]
212 configures the I/O Dump of SSL traffic, when LogLevel is set to Debug.
213 The default is none as this is far greater debugging resolution than
214 the typical administrator is prepared to untangle. [William Rowe]
216 *) mod_disk_cache: If possible, check if the size of an object to cache is
217 within the configured boundaries before actually saving data.
218 [Niklas Edmundsson <nikke acc.umu.se>]
220 *) mod_cache: Convert all values to seconds before comparing them when
221 checking whether to send a Warning header for a stale response.
222 PR 39713. [Owen Taylor <otaylor redhat.com>]
224 *) mod_disk_cache: Delete temporary files if they cannot be renamed to their
225 final name. [Davi Arnaut <davi haxent.com.br>]
227 *) Worker and event MPMs: Remove improper scoreboard updates which were
228 performed in the event of a fork() failure. [Chris Darroch]
230 *) Add support for fcgi:// proxies to mod_rewrite.
231 [Markus Schiegl <ms schiegl.com>]
233 *) Remove incorrect comments from scoreboard.h regarding conditional
234 loading of worker_score structure with mod_status, and remove unused
235 definitions relating to old life_status field.
236 [Chris Darroch <chrisd pearsoncmg.com>]
238 *) Remove allocation of memory for unused array of lb_score pointers
239 in ap_init_scoreboard(). [Chris Darroch <chrisd pearsoncmg.com>]
241 *) Add mod_proxy_fcgi, a FastCGI back end for mod_proxy.
242 [Garrett Rooney, Jim Jagielski, Paul Querna]
244 *) Event MPM: Fill in the scoreboard's tid field. PR 38736.
245 [Chris Darroch <chrisd pearsoncmg.com>]
247 *) mod_charset_lite: Remove Content-Length when output filter can
248 invalidate it. Warn when input filter can invalidate it.
251 *) Authz: Add the new module mod_authn_core that will provide common
252 authn directives such as 'AuthType', 'AuthName'. Move the directives
253 'AuthType' and 'AuthName' out of the core module and merge mod_authz_alias
254 into mod_authn_core. [Brad Nicholes]
256 *) Authz: Move the directives 'Order', 'Allow', 'Deny' and 'Satisfy'
257 into the new module mod_access_compat which can be loaded to provide
258 support for these directives.
261 *) Authz: Move the 'Require' directive from the core module as well as
262 add the directives '<SatisfyAll>', '<SatisfyOne>', '<RequireAlias>'
263 and 'Reject' to mod_authz_core. The new directives introduce 'AND/OR'
264 logic into the authorization processing. [Brad Nicholes]
266 *) Authz: Add the new module mod_authz_core which acts as the
267 authorization provider vector and contains common authz
268 directives. [Brad Nicholes]
270 *) Authz: Renamed mod_authz_dbm authz providers from 'group' and
271 'file-group' to 'dbm-group' and 'dbm-file-group'. [Brad Nicholes]
273 *) Authz: Added the new authz providers 'env', 'ip', 'host', 'all' to handle
274 host-based access control provided by mod_authz_host and invoked
275 through the 'Require' directive. [Brad Nicholes]
277 *) Authz: Convert all of the authz modules from hook based to
278 provider based. [Brad Nicholes]
280 *) mod_cache: Add CacheMinExpire directive to set the minimum time in
281 seconds to cache a document.
282 [Brian Akins <brian.akins turner.com>, Ruediger Pluem]
284 *) mod_authz_dbd: SQL authz with Login/Session support [Nick Kew]
286 *) Fix typo in ProxyStatus syntax error message.
287 [Christophe Jaillet <christophe.jaillet wanadoo.fr>]
289 *) Asynchronous write completion for the Event MPM. [Brian Pane]
291 *) Added an End-Of-Request bucket type. The logging of a request and
292 the freeing of its pool are now done when the EOR bucket is destroyed.
293 This has the effect of delaying the logging until right after the last
294 of the response is sent; ap_core_output_filter() calls the access logger
295 indirectly when it destroys the EOR bucket. [Brian Pane]
297 *) Rewrite of logresolve support utility: IPv6 addresses are now supported
298 and the format of statistical output has changed. [Colm MacCarthaigh]
300 *) Rewrite of ap_coreoutput_filter to do nonblocking writes [Brian Pane]
302 *) Added new connection states for handler and write completion
305 *) mod_cgid: Refuse to work on Solaris 10 due to OS bugs. PR 34264.
308 *) Teach mod_ssl to use arbitrary OIDs in an SSLRequire directive,
309 allowing string-valued client certificate attributes to be used for
310 access control, as in: SSLRequire "value" in OID("1.3.6.1.4.1.18060.1")
