2 Changes with Apache 2.3.0
3 [ When backported to 2.2.x, remove entry from this file ]
5 *) rotatelogs: Improve atomicity when using -l and cleaup code.
8 *) mod_ssl: Add support for OCSP validation of client certificates.
9 PR 41123. [Marc Stern <marc.stern approach.be>, Joe Orton]
11 *) mod_filter: Don't segfault on (unsupported) chained FilterProvider usage.
12 PR 43956 [Nick Kew, Ruediger Pluem]
14 *) mod_unique_id: Fix timestamp value in UNIQUE_ID.
15 PR 37064 [Kobayashi <kobayashi firstserver.co.jp>]
17 *) core: Handle unrecognised transfer-encodings.
20 *) mod_serf: New module for Reverse Proxying. [Paul Querna]
22 *) core: Add the option to keep aside a request body up to a certain
23 size that would otherwise be discarded, to be consumed by filters
24 such as mod_include. When enabled for a directory, POST requests
25 to shtml files can be passed through to embedded scripts as POST
26 requests, rather being downgraded to GET requests. [Graham Leggett]
28 *) mod_ssl: Fix TLS upgrade (RFC 2817) support. PR 41231. [Joe Orton]
30 *) scoreboard: Correctly declare ap_time_process_request.
31 PR 43789 [Tom Donovan <Tom.Donovan acm.org>]
33 *) mod_status: Add SeeRequestTail directive, which determines if
34 ExtendedStatus displays the 1st 63 characters of the request
35 or the last 63. Useful for those requests with large string
36 lengths and which only vary with the last several characters.
39 *) core; scoreboard: ap_get_scoreboard_worker(sbh) now takes the sbh member
40 from the connection rec, ap_get_scoreboard_worker(proc, thread) will now
41 provide the unusual legacy lookup. [William Rowe]
43 *) mpm winnt: fix null pointer dereference
44 PR 42572 [Davi Arnaut]
46 *) mod_proxy_http: Correctly forward unexpected interim (HTTP 1xx)
47 responses from the backend according to RFC2616. But make it
48 configurable in case something breaks on it.
51 *) mod_deflate: Don't leave a strong ETag in place while transforming
55 *) core: reinstate location walk to fix config for subrequests
56 PR 41960 [Jose Kahan <jose w3.org>]
58 *) mod_log_config: Add format options for %p so that the actual local
59 or remote port can be logged. PR 43415. [Adam Hasselbalch Hansen
60 <ahh@one.com>, Ruediger Pluem, Jeff Trawick]
62 *) mod_rewrite: Add the novary flag to RewriteCond.
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 *) mod_substitute: Added a new experimental output filter, which
82 performs inline response content pattern matching (including
83 regex) and substitution. [Jim Jagielski]
85 *) core: Change etag generation to produce identical results on
86 32-bit and 64-bit platforms. PR 40064. [Joe Orton]
88 *) ab: Add -r option to continue after socket receive errors.
89 [Filip Hanik <devlist hanik.com>]
91 *) mod_ldap: Fix the search limit parameter to ldap_search_ext_s()
92 for SDKs that define LDAP_NO_LIMIT to something other than -1.
93 [David Jones <oscaremma gmail.com>]
95 *) mod_dbd: Introduce configuration groups to allow inheritance by virtual
96 hosts of database configurations from the main server. Determine the
97 minimal set of distinct configurations and share connection pools
98 whenever possible. Allow virtual hosts to override inherited SQL
99 statements. PR 41302. [Chris Darroch]
101 *) core: Fix broken chunk filtering that causes all non blocking reads to be
102 converted into blocking reads. PR 41056. [Jean-Frederic Clere, Jim Jagielski]
104 *) apxs: Enhance -q flag to print all known variables and their values
105 when invoked without variable name(s).
106 [William Rowe, Sander Temme]
108 *) apxs: Eliminate run-time check for mod_so. PR 40653.
109 [David M. Lee <dmlee crossroads.com>]
111 *) beos MPM: Create pmain pool and run modules' child_init hooks when
112 entering ap_mpm_run(), then destroy pmain when exiting ap_mpm_run().
115 *) netware MPM: Destroy pmain pool when exiting ap_mpm_run() so that
116 cleanups registered in modules' child_init hooks are performed.
119 *) mod_dbd: Stash DBD connections in request_config of initial request
120 only, or else sub-requests and internal redirections may cause
121 entire DBD pool to be stashed in a single HTTP request. [Chris Darroch]
123 *) Fix issue which could cause error messages to be written to access logs
124 on Win32. PR 40476. [Tom Donovan <Tom.Donovan acm.org>]
126 *) The LockFile directive, which specifies the location of
127 the accept() mutex lockfile, is deprecated. Instead, the
128 AcceptMutex directive now takes an optional lockfile
129 location parameter, ala SSLMutex. [Jim Jagielski]
131 *) mod_authn_dbd: Export any additional columns queried in the SQL select
132 into the environment with the name AUTHENTICATE_<COLUMN>. This brings
133 mod_authn_dbd behaviour in line with mod_authnz_ldap. [Graham Leggett]
135 *) mod_dbd: Key the storage of prepared statements on the hex string
136 value of server_rec, rather than the server name, as the server name
137 may change (eg when the server name is set) at any time, causing
138 weird behaviour in modules dependent on mod_dbd. [Graham Leggett]
140 *) mod_proxy_fcgi: Added win32 build. [Mladen Turk]
142 *) sendfile_nonblocking() takes the _brigade_ as an argument, gets
143 the first bucket from the brigade, finds it not to be a FILE
144 bucket and barfs. The fix is to pass a bucket rather than a brigade.
145 [Niklas Edmundsson <nikke acc.umu.se>]
147 *) mod_rewrite: support rewritemap by SQL query [Nick Kew]
149 *) ap_get_server_version() has been removed. Third-party modules must
150 now use ap_get_server_banner() or ap_get_server_description().
153 *) All MPMs: Introduce a check_config phase between pre_config and
154 open_logs, to allow modules to review interdependent configuration
155 directive values and adjust them while messages can still be logged
156 to the console. Handle relevant MPM directives during this phase
157 and format messages for both the console and the error log, as
158 appropriate. [Chris Darroch]
160 *) mod_proxy: don't URLencode tilde in path component
161 [Stijn Hoop <stijn sandcat.nl>]
163 *) mpm_winnt: Fix return values from wait_for_many_objects.
164 The return value is index to the signaled thread in the
165 creted_threads array. We can not use WAIT_TIMEOUT because
166 his value is defined as 258, thus limiting the MaxThreads
167 to that value. [Mladen Turk]
169 *) core: Do not allow internal redirects like the DirectoryIndex of mod_dir
170 to circumvent the symbolic link checks imposed by FollowSymLinks and
171 SymLinksIfOwnerMatch. [Nick Kew, Ruediger Pluem, William Rowe]
173 *) mod_proxy: Support environment variable interpolation in reverse
174 proxying directives. [Nick Kew]
176 *) core: Add the filename of the configuration file to the warning message
177 about the useless use of AllowOverride. PR 39992.
178 [Darryl Miles <darryl darrylmiles.org>]
180 *) New SSLLogLevelDebugDump [ None (default) | IO (not bytes) | Bytes ]
181 configures the I/O Dump of SSL traffic, when LogLevel is set to Debug.
182 The default is none as this is far greater debugging resolution than
183 the typical administrator is prepared to untangle. [William Rowe]
185 *) mod_disk_cache: If possible, check if the size of an object to cache is
186 within the configured boundaries before actually saving data.
187 [Niklas Edmundsson <nikke acc.umu.se>]
189 *) mod_cache: Convert all values to seconds before comparing them when
190 checking whether to send a Warning header for a stale response.
191 PR 39713. [Owen Taylor <otaylor redhat.com>]
193 *) mod_disk_cache: Delete temporary files if they cannot be renamed to their
194 final name. [Davi Arnaut <davi haxent.com.br>]
196 *) Worker and event MPMs: Remove improper scoreboard updates which were
197 performed in the event of a fork() failure. [Chris Darroch]
199 *) Add support for fcgi:// proxies to mod_rewrite.
200 [Markus Schiegl <ms schiegl.com>]
202 *) Remove incorrect comments from scoreboard.h regarding conditional
203 loading of worker_score structure with mod_status, and remove unused
204 definitions relating to old life_status field.
205 [Chris Darroch <chrisd pearsoncmg.com>]
207 *) Remove allocation of memory for unused array of lb_score pointers
208 in ap_init_scoreboard(). [Chris Darroch <chrisd pearsoncmg.com>]
210 *) Add mod_proxy_fcgi, a FastCGI back end for mod_proxy.
211 [Garrett Rooney, Jim Jagielski, Paul Querna]
213 *) Event MPM: Fill in the scoreboard's tid field. PR 38736.
214 [Chris Darroch <chrisd pearsoncmg.com>]
216 *) mod_charset_lite: Remove Content-Length when output filter can
217 invalidate it. Warn when input filter can invalidate it.
220 *) Authz: Add the new module mod_authn_core that will provide common
221 authn directives such as 'AuthType', 'AuthName'. Move the directives
222 'AuthType' and 'AuthName' out of the core module and merge mod_authz_alias
223 into mod_authn_core. [Brad Nicholes]
225 *) Authz: Move the directives 'Order', 'Allow', 'Deny' and 'Satisfy'
226 into the new module mod_access_compat which can be loaded to provide
227 support for these directives.
230 *) Authz: Move the 'Require' directive from the core module as well as
231 add the directives '<SatisfyAll>', '<SatisfyOne>', '<RequireAlias>'
232 and 'Reject' to mod_authz_core. The new directives introduce 'AND/OR'
233 logic into the authorization processing. [Brad Nicholes]
235 *) Authz: Add the new module mod_authz_core which acts as the
236 authorization provider vector and contains common authz
237 directives. [Brad Nicholes]
239 *) Authz: Renamed mod_authz_dbm authz providers from 'group' and
240 'file-group' to 'dbm-group' and 'dbm-file-group'. [Brad Nicholes]
242 *) Authz: Added the new authz providers 'env', 'ip', 'host', 'all' to handle
243 host-based access control provided by mod_authz_host and invoked
244 through the 'Require' directive. [Brad Nicholes]
246 *) Authz: Convert all of the authz modules from hook based to
247 provider based. [Brad Nicholes]
249 *) mod_cache: Add CacheMinExpire directive to set the minimum time in
250 seconds to cache a document.
251 [Brian Akins <brian.akins turner.com>, Ruediger Pluem]
253 *) mod_authz_dbd: SQL authz with Login/Session support [Nick Kew]
255 *) Fix typo in ProxyStatus syntax error message.
256 [Christophe Jaillet <christophe.jaillet wanadoo.fr>]
258 *) Asynchronous write completion for the Event MPM. [Brian Pane]
260 *) Added an End-Of-Request bucket type. The logging of a request and
261 the freeing of its pool are now done when the EOR bucket is destroyed.
262 This has the effect of delaying the logging until right after the last
263 of the response is sent; ap_core_output_filter() calls the access logger
264 indirectly when it destroys the EOR bucket. [Brian Pane]
266 *) Rewrite of logresolve support utility: IPv6 addresses are now supported
267 and the format of statistical output has changed. [Colm MacCarthaigh]
269 *) Rewrite of ap_coreoutput_filter to do nonblocking writes [Brian Pane]
271 *) Added new connection states for handler and write completion
274 *) mod_cgid: Refuse to work on Solaris 10 due to OS bugs. PR 34264.
277 *) Teach mod_ssl to use arbitrary OIDs in an SSLRequire directive,
278 allowing string-valued client certificate attributes to be used for
279 access control, as in: SSLRequire "value" in OID("1.3.6.1.4.1.18060.1")
