2 Changes with Apache 2.3.0
3 [ When backported to 2.2.x, remove entry from this file ]
5 *) core: Lower memory consumption of ap_r* functions by reusing the brigade
6 instead of recreating it during each filter pass.
7 [Stefan Fritsch <sf sfritsch.de>]
9 *) mod_proxy_ajp: Use 64K as maximum AJP packet size. This is the maximum
10 length we can squeeze inside the AJP message packet.
13 *) core: Lower memory consumption in case that flush buckets are passed thru
14 the chunk filter as last bucket of a brigade. PR 23567.
15 [Stefan Fritsch <sf sfritsch.de>]
17 *) mod_proxy: Keep connections to the backend persistent in the HTTPS case.
20 *) rotatelogs: Improve atomicity when using -l and cleaup code.
21 PR 44004 [Rainer Jung]
23 *) mod_ssl: Add support for OCSP validation of client certificates.
24 PR 41123. [Marc Stern <marc.stern approach.be>, Joe Orton]
26 *) mod_unique_id: Fix timestamp value in UNIQUE_ID.
27 PR 37064 [Kobayashi <kobayashi firstserver.co.jp>]
29 *) mod_serf: New module for Reverse Proxying. [Paul Querna]
31 *) core: Add the option to keep aside a request body up to a certain
32 size that would otherwise be discarded, to be consumed by filters
33 such as mod_include. When enabled for a directory, POST requests
34 to shtml files can be passed through to embedded scripts as POST
35 requests, rather being downgraded to GET requests. [Graham Leggett]
37 *) mod_ssl: Fix TLS upgrade (RFC 2817) support. PR 41231. [Joe Orton]
39 *) scoreboard: Correctly declare ap_time_process_request.
40 PR 43789 [Tom Donovan <Tom.Donovan acm.org>]
42 *) core; scoreboard: ap_get_scoreboard_worker(sbh) now takes the sbh member
43 from the connection rec, ap_get_scoreboard_worker(proc, thread) will now
44 provide the unusual legacy lookup. [William Rowe]
46 *) mpm winnt: fix null pointer dereference
47 PR 42572 [Davi Arnaut]
49 *) mod_proxy_http: Correctly forward unexpected interim (HTTP 1xx)
50 responses from the backend according to RFC2616. But make it
51 configurable in case something breaks on it.
54 *) mod_deflate: Don't leave a strong ETag in place while transforming
58 *) core: reinstate location walk to fix config for subrequests
59 PR 41960 [Jose Kahan <jose w3.org>]
61 *) mod_log_config: Add format options for %p so that the actual local
62 or remote port can be logged. PR 43415. [Adam Hasselbalch Hansen
63 <ahh@one.com>, Ruediger Pluem, Jeff Trawick]
65 *) mod_include: Add an "if" directive syntax to test whether an URL
66 is accessible, and if so, conditionally display content. This
67 allows a webmaster to hide a link to a private page when the user
68 has no access to that page. [Graham Leggett]
70 *) mod_authnz_ldap, mod_authn_dbd: Tidy up the code to expose authn
71 parameters to the environment. Improve portability to
72 EBCDIC machines by using apr_toupper(). [Martin Kraemer]
74 *) mod_ldap, mod_authnzldap: Add support for nested groups (i.e. the ability
75 to authorize an authenticated user via a "require ldap-group X" directive
76 where the user is not in group X, but is in a subgroup contained in X.
77 PR 42891 [Paul J. Reder]
79 *) mod_ssl: Add support for caching SSL Sessions in memcached. [Paul Querna]
81 *) ab: Add -r option to continue after socket receive errors.
82 [Filip Hanik <devlist hanik.com>]
84 *) mod_ldap: Fix the search limit parameter to ldap_search_ext_s()
85 for SDKs that define LDAP_NO_LIMIT to something other than -1.
86 [David Jones <oscaremma gmail.com>]
88 *) mod_dbd: Introduce configuration groups to allow inheritance by virtual
89 hosts of database configurations from the main server. Determine the
90 minimal set of distinct configurations and share connection pools
91 whenever possible. Allow virtual hosts to override inherited SQL
92 statements. PR 41302. [Chris Darroch]
94 *) apxs: Enhance -q flag to print all known variables and their values
95 when invoked without variable name(s).
96 [William Rowe, Sander Temme]
98 *) apxs: Eliminate run-time check for mod_so. PR 40653.
99 [David M. Lee <dmlee crossroads.com>]
101 *) beos MPM: Create pmain pool and run modules' child_init hooks when
102 entering ap_mpm_run(), then destroy pmain when exiting ap_mpm_run().
105 *) netware MPM: Destroy pmain pool when exiting ap_mpm_run() so that
106 cleanups registered in modules' child_init hooks are performed.
109 *) mod_dbd: Stash DBD connections in request_config of initial request
110 only, or else sub-requests and internal redirections may cause
111 entire DBD pool to be stashed in a single HTTP request. [Chris Darroch]
113 *) Fix issue which could cause error messages to be written to access logs
114 on Win32. PR 40476. [Tom Donovan <Tom.Donovan acm.org>]
116 *) The LockFile directive, which specifies the location of
117 the accept() mutex lockfile, is deprecated. Instead, the
118 AcceptMutex directive now takes an optional lockfile
119 location parameter, ala SSLMutex. [Jim Jagielski]
121 *) mod_authn_dbd: Export any additional columns queried in the SQL select
122 into the environment with the name AUTHENTICATE_<COLUMN>. This brings
123 mod_authn_dbd behaviour in line with mod_authnz_ldap. [Graham Leggett]
125 *) mod_dbd: Key the storage of prepared statements on the hex string
126 value of server_rec, rather than the server name, as the server name
127 may change (eg when the server name is set) at any time, causing
128 weird behaviour in modules dependent on mod_dbd. [Graham Leggett]
130 *) mod_proxy_fcgi: Added win32 build. [Mladen Turk]
132 *) sendfile_nonblocking() takes the _brigade_ as an argument, gets
133 the first bucket from the brigade, finds it not to be a FILE
134 bucket and barfs. The fix is to pass a bucket rather than a brigade.
135 [Niklas Edmundsson <nikke acc.umu.se>]
137 *) mod_rewrite: support rewritemap by SQL query [Nick Kew]
139 *) ap_get_server_version() has been removed. Third-party modules must
140 now use ap_get_server_banner() or ap_get_server_description().
143 *) All MPMs: Introduce a check_config phase between pre_config and
144 open_logs, to allow modules to review interdependent configuration
145 directive values and adjust them while messages can still be logged
146 to the console. Handle relevant MPM directives during this phase
147 and format messages for both the console and the error log, as
148 appropriate. [Chris Darroch]
150 *) mod_proxy: don't URLencode tilde in path component
151 [Stijn Hoop <stijn sandcat.nl>]
153 *) mpm_winnt: Fix return values from wait_for_many_objects.
154 The return value is index to the signaled thread in the
155 creted_threads array. We can not use WAIT_TIMEOUT because
156 his value is defined as 258, thus limiting the MaxThreads
157 to that value. [Mladen Turk]
159 *) core: Do not allow internal redirects like the DirectoryIndex of mod_dir
160 to circumvent the symbolic link checks imposed by FollowSymLinks and
161 SymLinksIfOwnerMatch. [Nick Kew, Ruediger Pluem, William Rowe]
163 *) mod_proxy: Support environment variable interpolation in reverse
164 proxying directives. [Nick Kew]
166 *) core: Add the filename of the configuration file to the warning message
167 about the useless use of AllowOverride. PR 39992.
168 [Darryl Miles <darryl darrylmiles.org>]
170 *) New SSLLogLevelDebugDump [ None (default) | IO (not bytes) | Bytes ]
171 configures the I/O Dump of SSL traffic, when LogLevel is set to Debug.
172 The default is none as this is far greater debugging resolution than
173 the typical administrator is prepared to untangle. [William Rowe]
175 *) mod_disk_cache: If possible, check if the size of an object to cache is
176 within the configured boundaries before actually saving data.
177 [Niklas Edmundsson <nikke acc.umu.se>]
179 *) mod_cache: Convert all values to seconds before comparing them when
180 checking whether to send a Warning header for a stale response.
181 PR 39713. [Owen Taylor <otaylor redhat.com>]
183 *) mod_disk_cache: Delete temporary files if they cannot be renamed to their
184 final name. [Davi Arnaut <davi haxent.com.br>]
186 *) Worker and event MPMs: Remove improper scoreboard updates which were
187 performed in the event of a fork() failure. [Chris Darroch]
189 *) Add support for fcgi:// proxies to mod_rewrite.
190 [Markus Schiegl <ms schiegl.com>]
192 *) Remove incorrect comments from scoreboard.h regarding conditional
193 loading of worker_score structure with mod_status, and remove unused
194 definitions relating to old life_status field.
195 [Chris Darroch <chrisd pearsoncmg.com>]
197 *) Remove allocation of memory for unused array of lb_score pointers
198 in ap_init_scoreboard(). [Chris Darroch <chrisd pearsoncmg.com>]
200 *) Add mod_proxy_fcgi, a FastCGI back end for mod_proxy.
201 [Garrett Rooney, Jim Jagielski, Paul Querna]
203 *) Event MPM: Fill in the scoreboard's tid field. PR 38736.
204 [Chris Darroch <chrisd pearsoncmg.com>]
206 *) mod_charset_lite: Remove Content-Length when output filter can
207 invalidate it. Warn when input filter can invalidate it.
210 *) Authz: Add the new module mod_authn_core that will provide common
211 authn directives such as 'AuthType', 'AuthName'. Move the directives
212 'AuthType' and 'AuthName' out of the core module and merge mod_authz_alias
213 into mod_authn_core. [Brad Nicholes]
215 *) Authz: Move the directives 'Order', 'Allow', 'Deny' and 'Satisfy'
216 into the new module mod_access_compat which can be loaded to provide
217 support for these directives.
220 *) Authz: Move the 'Require' directive from the core module as well as
221 add the directives '<SatisfyAll>', '<SatisfyOne>', '<RequireAlias>'
222 and 'Reject' to mod_authz_core. The new directives introduce 'AND/OR'
223 logic into the authorization processing. [Brad Nicholes]
225 *) Authz: Add the new module mod_authz_core which acts as the
226 authorization provider vector and contains common authz
227 directives. [Brad Nicholes]
229 *) Authz: Renamed mod_authz_dbm authz providers from 'group' and
230 'file-group' to 'dbm-group' and 'dbm-file-group'. [Brad Nicholes]
232 *) Authz: Added the new authz providers 'env', 'ip', 'host', 'all' to handle
233 host-based access control provided by mod_authz_host and invoked
234 through the 'Require' directive. [Brad Nicholes]
236 *) Authz: Convert all of the authz modules from hook based to
237 provider based. [Brad Nicholes]
239 *) mod_cache: Add CacheMinExpire directive to set the minimum time in
240 seconds to cache a document.
241 [Brian Akins <brian.akins turner.com>, Ruediger Pluem]
243 *) mod_authz_dbd: SQL authz with Login/Session support [Nick Kew]
245 *) Fix typo in ProxyStatus syntax error message.
246 [Christophe Jaillet <christophe.jaillet wanadoo.fr>]
248 *) Asynchronous write completion for the Event MPM. [Brian Pane]
250 *) Added an End-Of-Request bucket type. The logging of a request and
251 the freeing of its pool are now done when the EOR bucket is destroyed.
252 This has the effect of delaying the logging until right after the last
253 of the response is sent; ap_core_output_filter() calls the access logger
254 indirectly when it destroys the EOR bucket. [Brian Pane]
256 *) Rewrite of logresolve support utility: IPv6 addresses are now supported
257 and the format of statistical output has changed. [Colm MacCarthaigh]
259 *) Rewrite of ap_coreoutput_filter to do nonblocking writes [Brian Pane]
261 *) Added new connection states for handler and write completion
264 *) mod_cgid: Refuse to work on Solaris 10 due to OS bugs. PR 34264.
267 *) Teach mod_ssl to use arbitrary OIDs in an SSLRequire directive,
268 allowing string-valued client certificate attributes to be used for
269 access control, as in: SSLRequire "value" in OID("1.3.6.1.4.1.18060.1")
