2 Changes with Apache 2.3.0
3 [ When backported to 2.2.x, remove entry from this file ]
5 *) mod_rewrite: Initialize hash needed by ap_register_rewrite_mapfunc early
6 enough. PR 44641 [Daniel Lescohier <daniel.lescohier cnet.com>]
8 *) mod_authn_dbd: Disambiguate and tidy database authentication
9 error messages. PR 43210. [Chris Darroch, Phil Endecott
10 <spam_from_apache_bugzilla chezphil.org>]
12 *) mod_cache: Handle If-Range correctly if the cached resource was stale.
13 PR 44579 [Ruediger Pluem]
15 *) mod_speling: remove regression from 1.3/2.0 behavior and
16 drop dependency between mod_speling and AcceptPathInfo.
17 PR 43562 [Jose Kahan <jose w3.org>]
19 *) mod_ldap: Correctly return all requested attribute values
20 when some attributes have a null value.
21 PR 44560 [Anders Kaseorg <anders kaseorg.com>]
23 *) core: check symlink ownership if both FollowSymlinks and
24 SymlinksIfOwnerMatch are set [Nick Kew]
26 *) core: fix origin checking in SymlinksIfOwnerMatch
27 PR 36783 [Robert L Mathews <rob-apache.org.bugs tigertech.net>]
29 *) rotatelogs: Added '-f' option to force rotatelogs to create the
30 logfile as soon as started, and not wait until it reads the
31 first entry. [Jim Jagielski]
33 *) mod_proxy: Do not try a direct connection if the connection via a
34 remote proxy failed before and the request has a request body.
37 *) mod_substitute: The default is now flattening the buckets after
38 each substitution. This was mostly done to abide by the
39 Principle Of Least Astonishment. The newly added 'q' flag allows for
40 the quicker, more efficient bucket-splitting if the user so
41 desires. [Jim Jagielski]
43 *) Added 'disablereuse' option for ProxyPass which, essentially,
44 disables connection pooling for the backend servers.
47 *) Activate mod_cache, mod_file_cache and mod_disc_cache as part of the
48 'most' set for '--enable-modules' and '--enable-shared-mods'. Include
49 mod_mem_cache in 'all' as well. [Dirk-Willem van Gulik]
51 *) Also install mod_so.h, mod_rewrite.h and mod_cache.h; as these
52 contain public function declarations which are useful for
53 third party module authors. PR 42431 [Dirk-Willem van Gulik].
55 *) mod_dir, mod_negotiation: pass the output filter information
56 to newly created sub requests; as these are later on used
57 as true requests with an internal redirect. This allows for
58 mod_cache et.al. to trap the results of the redirect.
59 [Dirk-Willem van Gulik, Ruediger Pluem]
61 *) ab: Use a 64 bit unsigned int instead of a signed long to count the
62 bytes transferred to avoid integer overflows. PR 44346 [Ruediger Pluem]
64 *) mod_proxy_ajp: Do not retry request in the case that we either failed to
65 sent a part of the request body or if the request is not idempotent.
66 PR 44334 [Ruediger Pluem]
68 *) ProxyPassReverse is now balancer aware. [Jim Jagielski]
70 *) rotatelogs: Don't leak memory when reopening the logfile.
71 PR 40183 [Ruediger Pluem, Takashi Sato <serai lans-tv.com>]
73 *) mod_ldap: Add support (taking advantage of the new APR capability)
74 for ldap rebind callback while chasing referrals. This allows direct
75 searches on LDAP servers (in particular MS Active Directory 2003+)
76 using referrals without the use of the global catalog.
77 PRs 26538, 40268, and 42557 [Paul J. Reder]
79 *) ab: Do not try to read non existing response bodies of HEAD requests.
80 PR 34275 [Takashi Sato <serai lans-tv.com>]
82 *) Support chroot on Unix-family platforms
83 PR 43596 [Dimitar Pashev <mitko banksoft-bg.com>]
85 *) mod_proxy_http: Return HTTP status codes instead of apr_status_t
86 values for errors encountered while forwarding the request body
87 PR 44165 [Eric Covener]
89 *) mod_ssl: Added server name indication support (SNI, RFC 4366).
90 PR 34607. [Kaspar Brand <asfbugz velox.ch>]. A test configuration
91 can be created with test/make_sni.sh [Dirk-Willem van Gulik].
93 *) ApacheMonitor.exe: Introduce --kill argument for use by the
94 installer. This will permit the installation tool to remove
95 all running instances before attempting to remove the .exe.
98 *) mod_proxy: Lower memory consumption for short lived connections.
99 PR 44026. [Ruediger Pluem]
101 *) mod_proxy: Keep connections to the backend persistent in the HTTPS case.
104 *) rotatelogs: Improve atomicity when using -l and cleaup code.
105 PR 44004 [Rainer Jung]
107 *) mod_ssl: Add support for OCSP validation of client certificates.
108 PR 41123. [Marc Stern <marc.stern approach.be>, Joe Orton]
110 *) mod_unique_id: Fix timestamp value in UNIQUE_ID.
111 PR 37064 [Kobayashi <kobayashi firstserver.co.jp>]
113 *) mod_serf: New module for Reverse Proxying. [Paul Querna]
115 *) core: Add the option to keep aside a request body up to a certain
116 size that would otherwise be discarded, to be consumed by filters
117 such as mod_include. When enabled for a directory, POST requests
118 to shtml files can be passed through to embedded scripts as POST
119 requests, rather being downgraded to GET requests. [Graham Leggett]
121 *) mod_ssl: Fix TLS upgrade (RFC 2817) support. PR 41231. [Joe Orton]
123 *) scoreboard: Correctly declare ap_time_process_request.
124 PR 43789 [Tom Donovan <Tom.Donovan acm.org>]
126 *) core; scoreboard: ap_get_scoreboard_worker(sbh) now takes the sbh member
127 from the connection rec, ap_get_scoreboard_worker(proc, thread) will now
128 provide the unusual legacy lookup. [William Rowe]
130 *) mpm winnt: fix null pointer dereference
131 PR 42572 [Davi Arnaut]
133 *) core: reinstate location walk to fix config for subrequests
134 PR 41960 [Jose Kahan <jose w3.org>]
136 *) mod_log_config: Add format options for %p so that the actual local
137 or remote port can be logged. PR 43415. [Adam Hasselbalch Hansen
138 <ahh@one.com>, Ruediger Pluem, Jeff Trawick]
140 *) mod_authnz_ldap, mod_authn_dbd: Tidy up the code to expose authn
141 parameters to the environment. Improve portability to
142 EBCDIC machines by using apr_toupper(). [Martin Kraemer]
144 *) mod_ldap, mod_authnzldap: Add support for nested groups (i.e. the ability
145 to authorize an authenticated user via a "require ldap-group X" directive
146 where the user is not in group X, but is in a subgroup contained in X.
147 PR 42891 [Paul J. Reder]
149 *) mod_ssl: Add support for caching SSL Sessions in memcached. [Paul Querna]
151 *) ab: Add -r option to continue after socket receive errors.
152 [Filip Hanik <devlist hanik.com>]
154 *) mod_ldap: Fix the search limit parameter to ldap_search_ext_s()
155 for SDKs that define LDAP_NO_LIMIT to something other than -1.
156 [David Jones <oscaremma gmail.com>]
158 *) apxs: Enhance -q flag to print all known variables and their values
159 when invoked without variable name(s).
160 [William Rowe, Sander Temme]
162 *) apxs: Eliminate run-time check for mod_so. PR 40653.
163 [David M. Lee <dmlee crossroads.com>]
165 *) beos MPM: Create pmain pool and run modules' child_init hooks when
166 entering ap_mpm_run(), then destroy pmain when exiting ap_mpm_run().
169 *) netware MPM: Destroy pmain pool when exiting ap_mpm_run() so that
170 cleanups registered in modules' child_init hooks are performed.
173 *) mod_dbd: Stash DBD connections in request_config of initial request
174 only, or else sub-requests and internal redirections may cause
175 entire DBD pool to be stashed in a single HTTP request. [Chris Darroch]
177 *) Fix issue which could cause error messages to be written to access logs
178 on Win32. PR 40476. [Tom Donovan <Tom.Donovan acm.org>]
180 *) The LockFile directive, which specifies the location of
181 the accept() mutex lockfile, is deprecated. Instead, the
182 AcceptMutex directive now takes an optional lockfile
183 location parameter, ala SSLMutex. [Jim Jagielski]
185 *) mod_authn_dbd: Export any additional columns queried in the SQL select
186 into the environment with the name AUTHENTICATE_<COLUMN>. This brings
187 mod_authn_dbd behaviour in line with mod_authnz_ldap. [Graham Leggett]
189 *) mod_dbd: Key the storage of prepared statements on the hex string
190 value of server_rec, rather than the server name, as the server name
191 may change (eg when the server name is set) at any time, causing
192 weird behaviour in modules dependent on mod_dbd. [Graham Leggett]
194 *) mod_proxy_fcgi: Added win32 build. [Mladen Turk]
196 *) sendfile_nonblocking() takes the _brigade_ as an argument, gets
197 the first bucket from the brigade, finds it not to be a FILE
198 bucket and barfs. The fix is to pass a bucket rather than a brigade.
199 [Niklas Edmundsson <nikke acc.umu.se>]
201 *) mod_rewrite: support rewritemap by SQL query [Nick Kew]
203 *) ap_get_server_version() has been removed. Third-party modules must
204 now use ap_get_server_banner() or ap_get_server_description().
207 *) All MPMs: Introduce a check_config phase between pre_config and
208 open_logs, to allow modules to review interdependent configuration
209 directive values and adjust them while messages can still be logged
210 to the console. Handle relevant MPM directives during this phase
211 and format messages for both the console and the error log, as
212 appropriate. [Chris Darroch]
214 *) mod_proxy: don't URLencode tilde in path component
215 [Stijn Hoop <stijn sandcat.nl>]
217 *) mpm_winnt: Fix return values from wait_for_many_objects.
218 The return value is index to the signaled thread in the
219 creted_threads array. We can not use WAIT_TIMEOUT because
220 his value is defined as 258, thus limiting the MaxThreads
221 to that value. [Mladen Turk]
223 *) core: Do not allow internal redirects like the DirectoryIndex of mod_dir
224 to circumvent the symbolic link checks imposed by FollowSymLinks and
225 SymLinksIfOwnerMatch. [Nick Kew, Ruediger Pluem, William Rowe]
227 *) mod_proxy: Support environment variable interpolation in reverse
228 proxying directives. [Nick Kew]
230 *) core: Add the filename of the configuration file to the warning message
231 about the useless use of AllowOverride. PR 39992.
232 [Darryl Miles <darryl darrylmiles.org>]
234 *) New SSLLogLevelDebugDump [ None (default) | IO (not bytes) | Bytes ]
235 configures the I/O Dump of SSL traffic, when LogLevel is set to Debug.
236 The default is none as this is far greater debugging resolution than
237 the typical administrator is prepared to untangle. [William Rowe]
239 *) mod_disk_cache: If possible, check if the size of an object to cache is
240 within the configured boundaries before actually saving data.
241 [Niklas Edmundsson <nikke acc.umu.se>]
243 *) mod_cache: Convert all values to seconds before comparing them when
244 checking whether to send a Warning header for a stale response.
245 PR 39713. [Owen Taylor <otaylor redhat.com>]
247 *) mod_disk_cache: Delete temporary files if they cannot be renamed to their
248 final name. [Davi Arnaut <davi haxent.com.br>]
250 *) Worker and event MPMs: Remove improper scoreboard updates which were
251 performed in the event of a fork() failure. [Chris Darroch]
253 *) Add support for fcgi:// proxies to mod_rewrite.
254 [Markus Schiegl <ms schiegl.com>]
256 *) Remove incorrect comments from scoreboard.h regarding conditional
257 loading of worker_score structure with mod_status, and remove unused
258 definitions relating to old life_status field.
259 [Chris Darroch <chrisd pearsoncmg.com>]
261 *) Remove allocation of memory for unused array of lb_score pointers
262 in ap_init_scoreboard(). [Chris Darroch <chrisd pearsoncmg.com>]
264 *) Add mod_proxy_fcgi, a FastCGI back end for mod_proxy.
265 [Garrett Rooney, Jim Jagielski, Paul Querna]
267 *) Event MPM: Fill in the scoreboard's tid field. PR 38736.
268 [Chris Darroch <chrisd pearsoncmg.com>]
270 *) mod_charset_lite: Remove Content-Length when output filter can
271 invalidate it. Warn when input filter can invalidate it.
274 *) Authz: Add the new module mod_authn_core that will provide common
275 authn directives such as 'AuthType', 'AuthName'. Move the directives
276 'AuthType' and 'AuthName' out of the core module and merge mod_authz_alias
277 into mod_authn_core. [Brad Nicholes]
279 *) Authz: Move the directives 'Order', 'Allow', 'Deny' and 'Satisfy'
280 into the new module mod_access_compat which can be loaded to provide
281 support for these directives.
284 *) Authz: Move the 'Require' directive from the core module as well as
285 add the directives '<SatisfyAll>', '<SatisfyOne>', '<RequireAlias>'
286 and 'Reject' to mod_authz_core. The new directives introduce 'AND/OR'
287 logic into the authorization processing. [Brad Nicholes]
289 *) Authz: Add the new module mod_authz_core which acts as the
290 authorization provider vector and contains common authz
291 directives. [Brad Nicholes]
293 *) Authz: Renamed mod_authz_dbm authz providers from 'group' and
294 'file-group' to 'dbm-group' and 'dbm-file-group'. [Brad Nicholes]
296 *) Authz: Added the new authz providers 'env', 'ip', 'host', 'all' to handle
297 host-based access control provided by mod_authz_host and invoked
298 through the 'Require' directive. [Brad Nicholes]
300 *) Authz: Convert all of the authz modules from hook based to
301 provider based. [Brad Nicholes]
303 *) mod_cache: Add CacheMinExpire directive to set the minimum time in
304 seconds to cache a document.
305 [Brian Akins <brian.akins turner.com>, Ruediger Pluem]
307 *) mod_authz_dbd: SQL authz with Login/Session support [Nick Kew]
309 *) Fix typo in ProxyStatus syntax error message.
310 [Christophe Jaillet <christophe.jaillet wanadoo.fr>]
312 *) Asynchronous write completion for the Event MPM. [Brian Pane]
314 *) Added an End-Of-Request bucket type. The logging of a request and
315 the freeing of its pool are now done when the EOR bucket is destroyed.
316 This has the effect of delaying the logging until right after the last
317 of the response is sent; ap_core_output_filter() calls the access logger
318 indirectly when it destroys the EOR bucket. [Brian Pane]
320 *) Rewrite of logresolve support utility: IPv6 addresses are now supported
321 and the format of statistical output has changed. [Colm MacCarthaigh]
323 *) Rewrite of ap_coreoutput_filter to do nonblocking writes [Brian Pane]
325 *) Added new connection states for handler and write completion
328 *) mod_cgid: Refuse to work on Solaris 10 due to OS bugs. PR 34264.
331 *) Teach mod_ssl to use arbitrary OIDs in an SSLRequire directive,
332 allowing string-valued client certificate attributes to be used for
333 access control, as in: SSLRequire "value" in OID("1.3.6.1.4.1.18060.1")
