3 Changes with Apache 2.3.9
5 *) mod_cache: Add the cache_status hook to register the final cache
6 decision hit/miss/revalidate. Add optional support for an X-Cache
7 and/or an X-Cache-Detail header to add the cache status to the
8 response. PR48241 [Graham Leggett]
10 *) mod_authz_host: Add 'local' provider that matches connections originating
11 on the local host. PR 19938. [Stefan Fritsch]
13 *) Event MPM: Fix crash accessing pollset on worker thread when child
14 process is exiting. [Jeff Trawick]
16 *) core: For process invocation (cgi, fcgid, piped loggers and so forth)
17 pass the system library path (LD_LIBRARY_PATH or platform-specific
18 variables) along with the system PATH, by default. Both should be
19 overridden together as desired using PassEnv etc; see mod_env.
22 *) mod_cache: Introduce CacheStoreExpired, to allow administrators to
23 capture a stale backend response, perform If-Modified-Since requests
24 against the backend, and serving from the cache all 304 responses.
25 This restores pre-2.2.4 cache behavior. [William Rowe]
27 *) mod_rewrite: Introduce <=, >= string comparison operators, and integer
28 comparators -lt, -le, -eq, -ge, and -gt. To help bash users and drop
29 the ambiguity of the symlink test "-ltest", introduce -h or -L as
30 symlink test operators. [William Rowe]
32 *) mod_cache: Give the cache provider the opportunity to choose to cache
33 or not cache based on the buckets present in the brigade, such as the
34 presence of a FILE bucket.
37 *) mod_authz_core: Allow authz providers to check args while reading the
38 config and allow to cache parsed args. Move 'all' and 'env' authz
39 providers from mod_authz_host to mod_authz_core. Add 'method' authz
40 provider depending on the HTTP method. [Stefan Fritsch]
42 *) mod_include: Move the request_rec within mod_include to be
43 exposed within include_ctx_t. [Graham Leggett]
45 *) mod_include: Reinstate support for UTF-8 character sets by allowing a
46 variable being echoed or set to be decoded and then encoded as separate
47 steps. PR47686 [Graham Leggett]
49 *) mod_cache: Add a discrete commit_entity() provider function within the
50 mod_cache provider interface which is called to indicate to the
51 provider that caching is complete, giving the provider the opportunity
52 to commit temporary files permanently to the cache in an atomic
53 fashion. Replace the inconsistent use of error cleanups with a formal
54 set of pool cleanups attached to a subpool, which is destroyed on error.
57 *) mod_cache: Change the signature of the store_body() provider function
58 within the mod_cache provider interface to support an "in" brigade
59 and an "out" brigade instead of just a single input brigade. This
60 gives a cache provider the option to consume only part of the brigade
61 passed to it, rather than the whole brigade as was required before.
62 This fixes an out of memory and a request timeout condition that would
63 occur when the original document was a large file. Introduce
64 CacheReadSize and CacheReadTime directives to mod_disk_cache to control
65 the amount of data to attempt to cache at a time. [Graham Leggett]
67 *) core: Add ErrorLogFormat to allow configuring error log format, including
68 additional information that is logged once per connection or request. Add
69 error log IDs for connections and request to allow correlating error log
70 lines and the corresponding access log entry. [Stefan Fritsch]
72 *) core: Disable sendfile by default. [Stefan Fritsch]
74 *) mod_cache: Check the request to determine whether we are allowed
75 to return cached content at all, and respect a "Cache-Control:
76 no-cache" header from a client. Previously, "no-cache" would
77 behave like "max-age=0". [Graham Leggett]
79 *) mod_cache: Use a proper filter context to hold filter data instead
80 of misusing the per-request configuration. Fixes a segfault on trunk
81 when the normal handler is used. [Graham Leggett]
83 *) mod_cgid: Log a warning if the ScriptSock path is truncated because
84 it is too long. PR 49388. [Stefan Fritsch]
86 *) vhosts: Do not allow _default_ in NameVirtualHost, or mixing *
87 and non-* ports on NameVirtualHost, or multiple NameVirtualHost
88 directives for the same address:port, or NameVirtualHost
89 directives with no matching VirtualHosts, or multiple ip-based
90 VirtualHost sections for the same address:port. These were
91 previously accepted with a warning, but the behavior was
92 undefined. [Dan Poirier]
94 *) mod_remoteip: Fix a segfault when using mod_remoteip in conjunction with
95 Allow/Deny. PR 49838. [Andrew Skalski <voltara gmail.com>]
97 *) core: DirectoryMatch can now match on the end of line character ($),
98 and sub-directories of matched directories are no longer implicitly
99 matched. PR49809 [Eric Covener]
101 *) Regexps: introduce new higher-level regexp utility including parsing
102 and executing perl-style regexp ops (e.g s/foo/bar/i) and regexp memory
105 Changes with Apache 2.3.8
107 *) suexec: Support large log files. PR 45856. [Stefan Fritsch]
109 *) core: Abort with sensible error message if no or more than one MPM is
110 loaded. [Stefan Fritsch]
112 *) mod_proxy: Rename erroronstatus to failonstatus.
113 [Daniel Ruggeri <DRuggeri primary.net>]
115 *) mod_dav_fs: Fix broken "creationdate" property.
116 Regression in version 2.3.7. [Rainer Jung]

121 mod_dav, mod_cache, mod_session: Fix Handling of requests without a path
122 segment. PR: 49246 [Mark Drayton, Jeff Trawick]
124 *) mod_ldap: Properly check the result returned by apr_ldap_init. PR 46076.
127 *) mod_rewrite: Log errors if rewrite map files cannot be opened. PR 49639.
130 *) mod_proxy_http: Support the 'ping' property for backend HTTP/1.1 servers
131 via leveraging 100-Continue as the initial "request".
134 *) core/mod_authz_core: Introduce new access_checker_ex hook that enables
135 mod_authz_core to bypass authentication if access should be allowed by
136 IP address/env var/... [Stefan Fritsch]
138 *) core: Introduce note_auth_failure hook to allow modules to add support
139 for additional auth types. This makes ap_note_auth_failure() work with
140 mod_auth_digest again. PR 48807. [Stefan Fritsch]
142 *) socache modules: return APR_NOTFOUND when a lookup is not found [Nick Kew]
144 *) mod_authn_cache: new module [Nick Kew]
146 *) configure: Add reallyall option for --enable-mods-shared. [Stefan Fritsch]
148 *) Fix Windows build when using VC6. [Gregg L. Smith <lists glewis com>]
150 *) mod_rewrite: Allow to set environment variables without explicitly
151 giving a value. [Rainer Jung]
153 *) mod_rewrite: Remove superfluous EOL from rewrite logging. [Rainer Jung]
155 *) mod_include: recognise "text/html; parameters" as text/html
156 PR 49616 [Andrey Chernov <ache nagual.pp.ru>]
158 *) CGI vars: allow PATH to be set by SetEnv, consistent with LD_LIBRARY_PATH
161 *) Core: Extra robustness: don't try authz and segfault if authn
162 fails to set r->user. Log bug and return 500 instead.

168 *) Update SSL cipher suite and add example for SSLHonorCipherOrder.
169 [Lars Eilebrecht, Rainer Jung]
171 *) move AddOutputFilterByType from core to mod_filter. This should
172 fix nasty side-effects that happen when content_type is set
173 more than once in processing a request, and make it fully
174 compatible with dynamic and proxied contents. [Nick Kew]
176 *) mod_log_config: Implement logging for sub second timestamps and
177 request end time. [Rainer Jung]
179 Changes with Apache 2.3.6
181 *) SECURITY: CVE-2009-3555 (cve.mitre.org)
182 mod_ssl: Comprehensive fix of the TLS renegotiation prefix injection
183 attack when compiled against OpenSSL version 0.9.8m or later. Introduces
184 the 'SSLInsecureRenegotiation' directive to reopen this vulnerability
185 and offer unsafe legacy renegotiation with clients which do not yet
186 support the new secure renegotiation protocol, RFC 5746.
187 [Joe Orton, and with thanks to the OpenSSL Team]
189 *) SECURITY: CVE-2009-3555 (cve.mitre.org)
190 mod_ssl: A partial fix for the TLS renegotiation prefix injection attack
191 by rejecting any client-initiated renegotiations. Forcibly disable
192 keepalive for the connection if there is any buffered data readable. Any
193 configuration which requires renegotiation for per-directory/location
194 access control is still vulnerable, unless using OpenSSL >= 0.9.8l.
195 [Joe Orton, Ruediger Pluem, Hartmut Keil <Hartmut.Keil adnovum.ch>]
197 *) SECURITY: CVE-2010-0408 (cve.mitre.org)
198 mod_proxy_ajp: Respond with HTTP_BAD_REQUEST when the body is not sent
199 when request headers indicate a request body is incoming; not a case of
200 HTTP_INTERNAL_SERVER_ERROR. [Niku Toivola <niku.toivola sulake.com>]
202 *) SECURITY: CVE-2010-0425 (cve.mitre.org)
203 mod_isapi: Do not unload an isapi .dll module until the request
204 processing is completed, avoiding orphaned callback pointers.
205 [Brett Gervasoni <brettg senseofsecurity.com>, Jeff Trawick]
207 *) core: Filter init functions are now run strictly once per request
208 before handler invocation. The init functions are no longer run
209 for connection filters. PR 49328. [Joe Orton]
211 *) core: Adjust the output filter chain correctly in an internal
212 redirect from a subrequest, preserving filters from the main
213 request as necessary. PR 17629. [Joe Orton]
215 *) mod_cache: Explicitly allow cache implementations to cache a 206 Partial
216 Response if they so choose to do so. Previously an attempt to cache a 206
217 was arbitrarily allowed if the response contained an Expires or
218 Cache-Control header, and arbitrarily denied if both headers were missing.
221 *) core: Add microsecond timestamp fractions, process id and thread id
222 to the error log. [Rainer Jung]
224 *) configure: The "most" module set gets build by default. [Rainer Jung]

245 mod_ssl/mod_proxy*: Adjust loglevels to be less verbose at levels info
247 mod_dumpio: Replace DumpIOLogLevel with trace log levels.
250 *) mod_ldap: LDAP caching was suppressed (and ldap-status handler returns
251 title page only) when any mod_ldap directives were used in VirtualHost
252 context. [Eric Covener]
254 *) mod_disk_cache: Decline the opportunity to cache if the response is
255 a 206 Partial Content. This stops a reverse proxied partial response
256 from becoming cached, and then being served in subsequent responses.
259 *) mod_deflate: avoid the risk of forwarding data before headers are set.

1133 browser. [Graham Leggett]
1135 *) mod_session_cookie: Add a session implementation capable of storing
1136 session information within cookies on the browser. Useful for high
1137 volume sites where server bound sessions are too resource intensive.
1140 *) mod_session: Add a generic session interface to unify the different
1141 attempts at saving persistent sessions across requests.
1144 *) core, authn/z: Avoid calling access control hooks for internal requests
1145 with configurations which match those of initial request. Revert to
1146 original behaviour (call access control hooks for internal requests
1147 with URIs different from initial request) if any access control hooks or
1148 providers are not registered as permitting this optimization.
1149 Introduce wrappers for access control hook and provider registration
1150 which can accept additional mode and flag data. [Chris Darroch]
1152 *) Introduced ap_expr API for expression evaluation.
1153 This is adapted from mod_include, which is the first module
1157 *) mod_authz_dbd: When redirecting after successful login/logout per
1158 AuthzDBDRedirectQuery, do not report authorization failure, and use
1159 first row returned by database query instead of last row.
1162 *) mod_ldap: Correctly return all requested attribute values
1163 when some attributes have a null value.

1172 *) Activate mod_cache, mod_file_cache and mod_disk_cache as part of the
1173 'most' set for '--enable-modules' and '--enable-shared-mods'. Include
1174 mod_mem_cache in 'all' as well. [Dirk-Willem van Gulik]
1176 *) Also install mod_so.h, mod_rewrite.h and mod_cache.h; as these
1177 contain public function declarations which are useful for
1178 third party module authors. PR 42431 [Dirk-Willem van Gulik].
1180 *) mod_dir, mod_negotiation: pass the output filter information
1181 to newly created sub requests; as these are later on used
1182 as true requests with an internal redirect. This allows for
1183 mod_cache et.al. to trap the results of the redirect.
1184 [Dirk-Willem van Gulik, Ruediger Pluem]
1186 *) mod_ldap: Add support (taking advantage of the new APR capability)
1187 for ldap rebind callback while chasing referrals. This allows direct
1188 searches on LDAP servers (in particular MS Active Directory 2003+)
1189 using referrals without the use of the global catalog.

1192 *) ApacheMonitor.exe: Introduce --kill argument for use by the
1193 installer. This will permit the installation tool to remove
1194 all running instances before attempting to remove the .exe.
1197 *) mod_ssl: Add support for OCSP validation of client certificates.

1200 *) mod_serf: New module for Reverse Proxying. [Paul Querna]
1202 *) core: Add the option to keep aside a request body up to a certain
1203 size that would otherwise be discarded, to be consumed by filters
1204 such as mod_include. When enabled for a directory, POST requests
1205 to shtml files can be passed through to embedded scripts as POST

1249 *) The LockFile directive, which specifies the location of
1250 the accept() mutex lockfile, is deprecated. Instead, the
1251 AcceptMutex directive now takes an optional lockfile
1252 location parameter, ala SSLMutex. [Jim Jagielski]
1254 *) mod_authn_dbd: Export any additional columns queried in the SQL select
1255 into the environment with the name AUTHENTICATE_<COLUMN>. This brings
1256 mod_authn_dbd behaviour in line with mod_authnz_ldap. [Graham Leggett]
1258 *) mod_dbd: Key the storage of prepared statements on the hex string
1259 value of server_rec, rather than the server name, as the server name
1260 may change (eg when the server name is set) at any time, causing
1261 weird behaviour in modules dependent on mod_dbd. [Graham Leggett]
1263 *) mod_proxy_fcgi: Added win32 build. [Mladen Turk]
1265 *) sendfile_nonblocking() takes the _brigade_ as an argument, gets
1266 the first bucket from the brigade, finds it not to be a FILE
1267 bucket and barfs. The fix is to pass a bucket rather than a brigade.

1270 *) mod_rewrite: support rewritemap by SQL query [Nick Kew]
1272 *) ap_get_server_version() has been removed. Third-party modules must
1273 now use ap_get_server_banner() or ap_get_server_description().
1276 *) All MPMs: Introduce a check_config phase between pre_config and
1277 open_logs, to allow modules to review interdependent configuration
1278 directive values and adjust them while messages can still be logged
1279 to the console. Handle relevant MPM directives during this phase
1280 and format messages for both the console and the error log, as
1281 appropriate. [Chris Darroch]
1283 *) core: Do not allow internal redirects like the DirectoryIndex of mod_dir

1289 The default is none as this is far greater debugging resolution than
1290 the typical administrator is prepared to untangle. [William Rowe]

1320 *) Authz: Add the new module mod_authn_core that will provide common
1321 authn directives such as 'AuthType', 'AuthName'. Move the directives
1322 'AuthType' and 'AuthName' out of the core module and merge mod_authz_alias
1323 into mod_authn_core. [Brad Nicholes]
1325 *) Authz: Move the directives 'Order', 'Allow', 'Deny' and 'Satisfy'
1326 into the new module mod_access_compat which can be loaded to provide
1327 support for these directives.
1330 *) Authz: Move the 'Require' directive from the core module as well as
1331 add the directives '<SatisfyAll>', '<SatisfyOne>', '<RequireAlias>'
1332 and 'Reject' to mod_authz_core. The new directives introduce 'AND/OR'
1333 logic into the authorization processing. [Brad Nicholes]
1335 *) Authz: Add the new module mod_authz_core which acts as the
1336 authorization provider vector and contains common authz
1337 directives. [Brad Nicholes]
1339 *) Authz: Renamed mod_authz_dbm authz providers from 'group' and
1340 'file-group' to 'dbm-group' and 'dbm-file-group'. [Brad Nicholes]
1342 *) Authz: Added the new authz providers 'env', 'ip', 'host', 'all' to handle
1343 host-based access control provided by mod_authz_host and invoked
1344 through the 'Require' directive. [Brad Nicholes]
1346 *) Authz: Convert all of the authz modules from hook based to

1356 [Christophe Jaillet <christophe.jaillet wanadoo.fr>]
1358 *) Asynchronous write completion for the Event MPM. [Brian Pane]
1360 *) Added an End-Of-Request bucket type. The logging of a request and
1361 the freeing of its pool are now done when the EOR bucket is destroyed.
1362 This has the effect of delaying the logging until right after the last
1363 of the response is sent; ap_core_output_filter() calls the access logger
1364 indirectly when it destroys the EOR bucket. [Brian Pane]
1366 *) Rewrite of logresolve support utility: IPv6 addresses are now supported
1367 and the format of statistical output has changed. [Colm MacCarthaigh]
1369 *) Rewrite of ap_coreoutput_filter to do nonblocking writes [Brian Pane]
1371 *) Added new connection states for handler and write completion
1374 *) mod_cgid: Refuse to work on Solaris 10 due to OS bugs. PR 34264.
1377 *) Teach mod_ssl to use arbitrary OIDs in an SSLRequire directive,
1378 allowing string-valued client certificate attributes to be used for
1379 access control, as in: SSLRequire "value" in OID("1.3.6.1.4.1.18060.1")
