2 Changes with Apache 2.3.0
3 [ When backported to 2.2.x, remove entry from this file ]
5 *) mod_unique_id: Fix timestamp value in UNIQUE_ID.
6 PR 37064 [Kobayashi <kobayashi firstserver.co.jp>]
8 *) core: Handle unrecognised transfer-encodings.
11 *) core: Avoid some unexpected connection closes by telling the client
12 that the connection is not persistent if the MPM process handling
13 the request is already exiting when the response header is built.
16 *) mod_serf: New module for Reverse Proxying. [Paul Querna]
18 *) mod_autoindex: Generate valid XHTML output by adding the xhtml
19 namespace. PR 43649 [Jose Kahan <jose w3.org>]
21 *) core: Add the option to keep aside a request body up to a certain
22 size that would otherwise be discarded, to be consumed by filters
23 such as mod_include. When enabled for a directory, POST requests
24 to shtml files can be passed through to embedded scripts as POST
25 requests, rather being downgraded to GET requests. [Graham Leggett]
27 *) mod_ssl: Fix TLS upgrade (RFC 2817) support. PR 41231. [Joe Orton]
29 *) scoreboard: Correctly declare ap_time_process_request.
30 PR 43789 [Tom Donovan <Tom.Donovan acm.org>]
32 *) mod_status: Add SeeRequestTail directive, which determines if
33 ExtendedStatus displays the 1st 63 characters of the request
34 or the last 63. Useful for those requests with large string
35 lengths and which only vary with the last several characters.
38 *) mod_proxy: add "nocanon" keyword to ProxyPass, to suppress
39 URI-canonicalisation in a reverse proxy.
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 *) mod_proxy_http: Don't escape/unescape forward-proxied URLs
49 *) mpm winnt: fix null pointer dereference
50 PR 42572 [Davi Arnaut]
52 *) mod_proxy_http: Correctly forward unexpected interim (HTTP 1xx)
53 responses from the backend according to RFC2616. But make it
54 configurable in case something breaks on it.
57 *) mod_deflate: Don't leave a strong ETag in place while transforming
61 *) core: reinstate location walk to fix config for subrequests
62 PR 41960 [Jose Kahan <jose w3.org>]
64 *) mod_log_config: Add format options for %p so that the actual local
65 or remote port can be logged. PR 43415. [Adam Hasselbalch Hansen
66 <ahh@one.com>, Ruediger Pluem, Jeff Trawick]
68 *) mod_rewrite: Add the novary flag to RewriteCond.
71 *) mod_include: Add an "if" directive syntax to test whether an URL
72 is accessible, and if so, conditionally display content. This
73 allows a webmaster to hide a link to a private page when the user
74 has no access to that page. [Graham Leggett]
76 *) mod_authnz_ldap, mod_authn_dbd: Tidy up the code to expose authn
77 parameters to the environment. Improve portability to
78 EBCDIC machines by using apr_toupper(). [Martin Kraemer]
80 *) mod_ldap, mod_authnzldap: Add support for nested groups (i.e. the ability
81 to authorize an authenticated user via a "require ldap-group X" directive
82 where the user is not in group X, but is in a subgroup contained in X.
83 PR 42891 [Paul J. Reder]
85 *) mod_ssl: Add support for caching SSL Sessions in memcached. [Paul Querna]
87 *) mod_substitute: Added a new experimental output filter, which
88 performs inline response content pattern matching (including
89 regex) and substitution. [Jim Jagielski]
91 *) core: Change etag generation to produce identical results on
92 32-bit and 64-bit platforms. PR 40064. [Joe Orton]
94 *) ab: Add -r option to continue after socket receive errors.
95 [Filip Hanik <devlist hanik.com>]
97 *) mod_ldap: Fix the search limit parameter to ldap_search_ext_s()
98 for SDKs that define LDAP_NO_LIMIT to something other than -1.
99 [David Jones <oscaremma gmail.com>]
101 *) mod_dbd: Introduce configuration groups to allow inheritance by virtual
102 hosts of database configurations from the main server. Determine the
103 minimal set of distinct configurations and share connection pools
104 whenever possible. Allow virtual hosts to override inherited SQL
105 statements. PR 41302. [Chris Darroch]
107 *) core: Fix broken chunk filtering that causes all non blocking reads to be
108 converted into blocking reads. PR 41056. [Jean-Frederic Clere, Jim Jagielski]
110 *) apxs: Enhance -q flag to print all known variables and their values
111 when invoked without variable name(s).
112 [William Rowe, Sander Temme]
114 *) apxs: Eliminate run-time check for mod_so. PR 40653.
115 [David M. Lee <dmlee crossroads.com>]
117 *) beos MPM: Create pmain pool and run modules' child_init hooks when
118 entering ap_mpm_run(), then destroy pmain when exiting ap_mpm_run().
121 *) netware MPM: Destroy pmain pool when exiting ap_mpm_run() so that
122 cleanups registered in modules' child_init hooks are performed.
125 *) mod_dbd: Stash DBD connections in request_config of initial request
126 only, or else sub-requests and internal redirections may cause
127 entire DBD pool to be stashed in a single HTTP request. [Chris Darroch]
129 *) Fix issue which could cause error messages to be written to access logs
130 on Win32. PR 40476. [Tom Donovan <Tom.Donovan acm.org>]
132 *) The LockFile directive, which specifies the location of
133 the accept() mutex lockfile, is deprecated. Instead, the
134 AcceptMutex directive now takes an optional lockfile
135 location parameter, ala SSLMutex. [Jim Jagielski]
137 *) mod_authn_dbd: Export any additional columns queried in the SQL select
138 into the environment with the name AUTHENTICATE_<COLUMN>. This brings
139 mod_authn_dbd behaviour in line with mod_authnz_ldap. [Graham Leggett]
141 *) mod_dbd: Key the storage of prepared statements on the hex string
142 value of server_rec, rather than the server name, as the server name
143 may change (eg when the server name is set) at any time, causing
144 weird behaviour in modules dependent on mod_dbd. [Graham Leggett]
146 *) mod_proxy_fcgi: Added win32 build. [Mladen Turk]
148 *) sendfile_nonblocking() takes the _brigade_ as an argument, gets
149 the first bucket from the brigade, finds it not to be a FILE
150 bucket and barfs. The fix is to pass a bucket rather than a brigade.
151 [Niklas Edmundsson <nikke acc.umu.se>]
153 *) mod_rewrite: support rewritemap by SQL query [Nick Kew]
155 *) ap_get_server_version() has been removed. Third-party modules must
156 now use ap_get_server_banner() or ap_get_server_description().
159 *) All MPMs: Introduce a check_config phase between pre_config and
160 open_logs, to allow modules to review interdependent configuration
161 directive values and adjust them while messages can still be logged
162 to the console. Handle relevant MPM directives during this phase
163 and format messages for both the console and the error log, as
164 appropriate. [Chris Darroch]
166 *) mod_proxy: don't URLencode tilde in path component
167 [Stijn Hoop <stijn sandcat.nl>]
169 *) mpm_winnt: Fix return values from wait_for_many_objects.
170 The return value is index to the signaled thread in the
171 creted_threads array. We can not use WAIT_TIMEOUT because
172 his value is defined as 258, thus limiting the MaxThreads
173 to that value. [Mladen Turk]
175 *) core: Do not allow internal redirects like the DirectoryIndex of mod_dir
176 to circumvent the symbolic link checks imposed by FollowSymLinks and
177 SymLinksIfOwnerMatch. [Nick Kew, Ruediger Pluem, William Rowe]
179 *) mod_proxy: Support environment variable interpolation in reverse
180 proxying directives. [Nick Kew]
182 *) core: Add the filename of the configuration file to the warning message
183 about the useless use of AllowOverride. PR 39992.
184 [Darryl Miles <darryl darrylmiles.org>]
186 *) New SSLLogLevelDebugDump [ None (default) | IO (not bytes) | Bytes ]
187 configures the I/O Dump of SSL traffic, when LogLevel is set to Debug.
188 The default is none as this is far greater debugging resolution than
189 the typical administrator is prepared to untangle. [William Rowe]
191 *) mod_disk_cache: If possible, check if the size of an object to cache is
192 within the configured boundaries before actually saving data.
193 [Niklas Edmundsson <nikke acc.umu.se>]
195 *) mod_cache: Convert all values to seconds before comparing them when
196 checking whether to send a Warning header for a stale response.
197 PR 39713. [Owen Taylor <otaylor redhat.com>]
199 *) mod_disk_cache: Delete temporary files if they cannot be renamed to their
200 final name. [Davi Arnaut <davi haxent.com.br>]
202 *) Worker and event MPMs: Remove improper scoreboard updates which were
203 performed in the event of a fork() failure. [Chris Darroch]
205 *) Add support for fcgi:// proxies to mod_rewrite.
206 [Markus Schiegl <ms schiegl.com>]
208 *) Remove incorrect comments from scoreboard.h regarding conditional
209 loading of worker_score structure with mod_status, and remove unused
210 definitions relating to old life_status field.
211 [Chris Darroch <chrisd pearsoncmg.com>]
213 *) Remove allocation of memory for unused array of lb_score pointers
214 in ap_init_scoreboard(). [Chris Darroch <chrisd pearsoncmg.com>]
216 *) Add mod_proxy_fcgi, a FastCGI back end for mod_proxy.
217 [Garrett Rooney, Jim Jagielski, Paul Querna]
219 *) Event MPM: Fill in the scoreboard's tid field. PR 38736.
220 [Chris Darroch <chrisd pearsoncmg.com>]
222 *) mod_charset_lite: Remove Content-Length when output filter can
223 invalidate it. Warn when input filter can invalidate it.
226 *) Authz: Add the new module mod_authn_core that will provide common
227 authn directives such as 'AuthType', 'AuthName'. Move the directives
228 'AuthType' and 'AuthName' out of the core module and merge mod_authz_alias
229 into mod_authn_core. [Brad Nicholes]
231 *) Authz: Move the directives 'Order', 'Allow', 'Deny' and 'Satisfy'
232 into the new module mod_access_compat which can be loaded to provide
233 support for these directives.
236 *) Authz: Move the 'Require' directive from the core module as well as
237 add the directives '<SatisfyAll>', '<SatisfyOne>', '<RequireAlias>'
238 and 'Reject' to mod_authz_core. The new directives introduce 'AND/OR'
239 logic into the authorization processing. [Brad Nicholes]
241 *) Authz: Add the new module mod_authz_core which acts as the
242 authorization provider vector and contains common authz
243 directives. [Brad Nicholes]
245 *) Authz: Renamed mod_authz_dbm authz providers from 'group' and
246 'file-group' to 'dbm-group' and 'dbm-file-group'. [Brad Nicholes]
248 *) Authz: Added the new authz providers 'env', 'ip', 'host', 'all' to handle
249 host-based access control provided by mod_authz_host and invoked
250 through the 'Require' directive. [Brad Nicholes]
252 *) Authz: Convert all of the authz modules from hook based to
253 provider based. [Brad Nicholes]
255 *) mod_cache: Add CacheMinExpire directive to set the minimum time in
256 seconds to cache a document.
257 [Brian Akins <brian.akins turner.com>, Ruediger Pluem]
259 *) mod_authz_dbd: SQL authz with Login/Session support [Nick Kew]
261 *) Fix typo in ProxyStatus syntax error message.
262 [Christophe Jaillet <christophe.jaillet wanadoo.fr>]
264 *) Asynchronous write completion for the Event MPM. [Brian Pane]
266 *) Added an End-Of-Request bucket type. The logging of a request and
267 the freeing of its pool are now done when the EOR bucket is destroyed.
268 This has the effect of delaying the logging until right after the last
269 of the response is sent; ap_core_output_filter() calls the access logger
270 indirectly when it destroys the EOR bucket. [Brian Pane]
272 *) Rewrite of logresolve support utility: IPv6 addresses are now supported
273 and the format of statistical output has changed. [Colm MacCarthaigh]
275 *) Rewrite of ap_coreoutput_filter to do nonblocking writes [Brian Pane]
277 *) Added new connection states for handler and write completion
280 *) mod_cgid: Refuse to work on Solaris 10 due to OS bugs. PR 34264.
283 *) Teach mod_ssl to use arbitrary OIDs in an SSLRequire directive,
284 allowing string-valued client certificate attributes to be used for
285 access control, as in: SSLRequire "value" in OID("1.3.6.1.4.1.18060.1")
