3 [ When backported to 2.2.x, remove entry from this file ]
5 *) mod_proxy_http: strip hop-by-hop response headers
8 *) HTTP protocol: Add "DefaultType none" option.
9 PR 13986 and PR 16139 [Nick Kew]
11 *) core: reinstate location walk to fix config for subrequests
12 PR 41960 [Jose Kahan <jose w3.org>]
14 *) mod_log_config: Add format options for %p so that the actual local
15 or remote port can be logged. PR 43415. [Adam Hasselbalch Hansen
16 <ahh@one.com>, Ruediger Pluem, Jeff Trawick]
18 *) scoreboard: improve error message on apr_shm_create failure
21 *) mod_rewrite: Add the novary flag to RewriteCond.
24 *) mod_proxy_http: Propagate Proxy-Authorization header correctly.
27 *) mod_rewrite: Add option to suppress URL unescaping
28 PR 34602 [Guenther Gsenger <guenther.gsenger gmail.com>]
30 *) mod_include: Add an "if" directive syntax to test whether an URL
31 is accessible, and if so, conditionally display content. This
32 allows a webmaster to hide a link to a private page when the user
33 has no access to that page. [Graham Leggett]
35 *) mod_authnz_ldap, mod_authn_dbd: Tidy up the code to expose authn
36 parameters to the environment. Improve portability to
37 EBCDIC machines by using apr_toupper(). [Martin Kraemer]
39 *) mod_ldap, mod_authnzldap: Add support for nested groups (i.e. the ability
40 to authorize an authenticated user via a "require ldap-group X" directive
41 where the user is not in group X, but is in a subgroup contained in X.
42 PR 42891 [Paul J. Reder]
44 *) Event MPM: Add support for running under mod_ssl, by reverting to the
45 Worker MPM behaviors, when run under an input filter that buffers
46 its own data. [Paul Querna]
48 *) mod_ssl: Add support for caching SSL Sessions in memcached. [Paul Querna]
50 *) mod_substitute: Added a new experimental output filter, which
51 performs inline response content pattern matching (including
52 regex) and substitution. [Jim Jagielski]
54 *) core: Change etag generation to produce identical results on
55 32-bit and 64-bit platforms. PR 40064. [Joe Orton]
57 *) ab: Add -r option to continue after socket receive errors.
58 [Filip Hanik <devlist hanik.com>]
60 *) mod_ldap: Fix the search limit parameter to ldap_search_ext_s()
61 for SDKs that define LDAP_NO_LIMIT to something other than -1.
62 [David Jones <oscaremma gmail.com>]
64 *) mod_dbd: Introduce configuration groups to allow inheritance by virtual
65 hosts of database configurations from the main server. Determine the
66 minimal set of distinct configurations and share connection pools
67 whenever possible. Allow virtual hosts to override inherited SQL
68 statements. PR 41302. [Chris Darroch]
70 *) core: Fix broken chunk filtering that causes all non blocking reads to be
71 converted into blocking reads. PR 41056. [Jean-Frederic Clere, Jim Jagielski]
73 *) apxs: Enhance -q flag to print all known variables and their values
74 when invoked without variable name(s).
75 [William Rowe, Sander Temme]
77 *) apxs: Eliminate run-time check for mod_so. PR 40653.
78 [David M. Lee <dmlee crossroads.com>]
80 *) beos MPM: Create pmain pool and run modules' child_init hooks when
81 entering ap_mpm_run(), then destroy pmain when exiting ap_mpm_run().
84 *) netware MPM: Destroy pmain pool when exiting ap_mpm_run() so that
85 cleanups registered in modules' child_init hooks are performed.
88 *) mod_dbd: Stash DBD connections in request_config of initial request
89 only, or else sub-requests and internal redirections may cause
90 entire DBD pool to be stashed in a single HTTP request. [Chris Darroch]
92 *) Fix issue which could cause error messages to be written to access logs
93 on Win32. PR 40476. [Tom Donovan <Tom.Donovan acm.org>]
95 *) The LockFile directive, which specifies the location of
96 the accept() mutex lockfile, is deprecated. Instead, the
97 AcceptMutex directive now takes an optional lockfile
98 location parameter, ala SSLMutex. [Jim Jagielski]
100 *) mod_authn_dbd: Export any additional columns queried in the SQL select
101 into the environment with the name AUTHENTICATE_<COLUMN>. This brings
102 mod_authn_dbd behaviour in line with mod_authnz_ldap. [Graham Leggett]
104 *) mod_dbd: Key the storage of prepared statements on the hex string
105 value of server_rec, rather than the server name, as the server name
106 may change (eg when the server name is set) at any time, causing
107 weird behaviour in modules dependent on mod_dbd. [Graham Leggett]
109 *) mod_proxy_fcgi: Added win32 build. [Mladen Turk]
111 *) sendfile_nonblocking() takes the _brigade_ as an argument, gets
112 the first bucket from the brigade, finds it not to be a FILE
113 bucket and barfs. The fix is to pass a bucket rather than a brigade.
114 [Niklas Edmundsson <nikke acc.umu.se>]
116 *) mod_rewrite: support rewritemap by SQL query [Nick Kew]
118 *) ap_get_server_version() has been removed. Third-party modules must
119 now use ap_get_server_banner() or ap_get_server_description().
122 *) All MPMs: Introduce a check_config phase between pre_config and
123 open_logs, to allow modules to review interdependent configuration
124 directive values and adjust them while messages can still be logged
125 to the console. Handle relevant MPM directives during this phase
126 and format messages for both the console and the error log, as
127 appropriate. [Chris Darroch]
129 *) mod_proxy: don't URLencode tilde in path component
130 [Stijn Hoop <stijn sandcat.nl>]
132 *) mpm_winnt: Fix return values from wait_for_many_objects.
133 The return value is index to the signaled thread in the
134 creted_threads array. We can not use WAIT_TIMEOUT because
135 his value is defined as 258, thus limiting the MaxThreads
136 to that value. [Mladen Turk]
138 *) core: Do not allow internal redirects like the DirectoryIndex of mod_dir
139 to circumvent the symbolic link checks imposed by FollowSymLinks and
140 SymLinksIfOwnerMatch. [Nick Kew, Ruediger Pluem, William Rowe]
142 *) mod_proxy: Support environment variable interpolation in reverse
143 proxying directives. [Nick Kew]
145 *) core: Add the filename of the configuration file to the warning message
146 about the useless use of AllowOverride. PR 39992.
147 [Darryl Miles <darryl darrylmiles.org>]
149 *) New SSLLogLevelDebugDump [ None (default) | IO (not bytes) | Bytes ]
150 configures the I/O Dump of SSL traffic, when LogLevel is set to Debug.
151 The default is none as this is far greater debugging resolution than
152 the typical administrator is prepared to untangle. [William Rowe]
154 *) mod_disk_cache: If possible, check if the size of an object to cache is
155 within the configured boundaries before actually saving data.
156 [Niklas Edmundsson <nikke acc.umu.se>]
158 *) mod_cache: Convert all values to seconds before comparing them when
159 checking whether to send a Warning header for a stale response.
160 PR 39713. [Owen Taylor <otaylor redhat.com>]
162 *) mod_disk_cache: Delete temporary files if they cannot be renamed to their
163 final name. [Davi Arnaut <davi haxent.com.br>]
165 *) Worker and event MPMs: Remove improper scoreboard updates which were
166 performed in the event of a fork() failure. [Chris Darroch]
168 *) Add support for fcgi:// proxies to mod_rewrite.
169 [Markus Schiegl <ms schiegl.com>]
171 *) Remove incorrect comments from scoreboard.h regarding conditional
172 loading of worker_score structure with mod_status, and remove unused
173 definitions relating to old life_status field.
174 [Chris Darroch <chrisd pearsoncmg.com>]
176 *) Remove allocation of memory for unused array of lb_score pointers
177 in ap_init_scoreboard(). [Chris Darroch <chrisd pearsoncmg.com>]
179 *) Add mod_proxy_fcgi, a FastCGI back end for mod_proxy.
180 [Garrett Rooney, Jim Jagielski, Paul Querna]
182 *) Event MPM: Fill in the scoreboard's tid field. PR 38736.
183 [Chris Darroch <chrisd pearsoncmg.com>]
185 *) mod_charset_lite: Remove Content-Length when output filter can
186 invalidate it. Warn when input filter can invalidate it.
189 *) Authz: Add the new module mod_authn_core that will provide common
190 authn directives such as 'AuthType', 'AuthName'. Move the directives
191 'AuthType' and 'AuthName' out of the core module and merge mod_authz_alias
192 into mod_authn_core. [Brad Nicholes]
194 *) Authz: Move the directives 'Order', 'Allow', 'Deny' and 'Satisfy'
195 into the new module mod_access_compat which can be loaded to provide
196 support for these directives.
199 *) Authz: Move the 'Require' directive from the core module as well as
200 add the directives '<SatisfyAll>', '<SatisfyOne>', '<RequireAlias>'
201 and 'Reject' to mod_authz_core. The new directives introduce 'AND/OR'
202 logic into the authorization processing. [Brad Nicholes]
204 *) Authz: Add the new module mod_authz_core which acts as the
205 authorization provider vector and contains common authz
206 directives. [Brad Nicholes]
208 *) Authz: Renamed mod_authz_dbm authz providers from 'group' and
209 'file-group' to 'dbm-group' and 'dbm-file-group'. [Brad Nicholes]
211 *) Authz: Added the new authz providers 'env', 'ip', 'host', 'all' to handle
212 host-based access control provided by mod_authz_host and invoked
213 through the 'Require' directive. [Brad Nicholes]
215 *) Authz: Convert all of the authz modules from hook based to
216 provider based. [Brad Nicholes]
218 *) mod_cache: Add CacheMinExpire directive to set the minimum time in
219 seconds to cache a document.
220 [Brian Akins <brian.akins turner.com>, Ruediger Pluem]
222 *) mod_authz_dbd: SQL authz with Login/Session support [Nick Kew]
224 *) Fix typo in ProxyStatus syntax error message.
225 [Christophe Jaillet <christophe.jaillet wanadoo.fr>]
227 *) Asynchronous write completion for the Event MPM. [Brian Pane]
229 *) Added an End-Of-Request bucket type. The logging of a request and
230 the freeing of its pool are now done when the EOR bucket is destroyed.
231 This has the effect of delaying the logging until right after the last
232 of the response is sent; ap_core_output_filter() calls the access logger
233 indirectly when it destroys the EOR bucket. [Brian Pane]
235 *) Rewrite of logresolve support utility: IPv6 addresses are now supported
236 and the format of statistical output has changed. [Colm MacCarthaigh]
238 *) Rewrite of ap_coreoutput_filter to do nonblocking writes [Brian Pane]
240 *) Added new connection states for handler and write completion
243 *) mod_cgid: Refuse to work on Solaris 10 due to OS bugs. PR 34264.
246 *) Teach mod_ssl to use arbitrary OIDs in an SSLRequire directive,
247 allowing string-valued client certificate attributes to be used for
248 access control, as in: SSLRequire "value" in OID("1.3.6.1.4.1.18060.1")
