49 expression. [Stefan Fritsch]
51 *) mod_proxy: Fix ProxyPassInterpolateEnv directive. PR 50292.
54 *) suEXEC: Add Suexec directive to disable suEXEC without renaming the
55 binary (Suexec Off), or force startup failure if suEXEC is required
56 but not supported (Suexec On). Change SuexecUserGroup to fail
57 startup instead of just printing a warning if suEXEC is disabled.
60 *) core: Add Error directive for aborting startup or htaccess processing
61 with a specified error message. [Jeff Trawick]
63 *) mod_rewrite: Fix the RewriteEngine directive to work within a
64 location. Previously, once RewriteEngine was switched on globally,
65 it was impossible to switch off. [Graham Leggett]
67 *) core, mod_include, mod_ssl: Move the expression parser derived from
68 mod_include back into mod_include. Replace ap_expr with a parser
69 derived from mod_ssl's parser. Make mod_ssl use the new parser. Rework
70 ap_expr's public interface and provide hooks for modules to add variables
71 and functions. [Stefan Fritsch]
73 *) core: Do the hook sorting earlier so that the hooks are properly sorted
74 for the pre_config hook and during parsing the config. [Stefan Fritsch]
76 *) core: In the absence of any AllowOverride directives, the default is now
77 "None" instead of "All". PR49823 [Eric Covener]

101 request (RFC 2616 9.6). PR 42978. [Stefan Fritsch]
103 *) mod_dav: Send 400 error if malformed Content-Range header is received for
104 a put request (RFC 2616 14.16). PR 49825. [Stefan Fritsch]
106 *) mod_proxy: Release the backend connection as soon as EOS is detected,
107 so the backend isn't forced to wait for the client to eventually
108 acknowledge the data. [Graham Leggett]
110 *) mod_proxy: Optimise ProxyPass within a Location so that it is stored
111 per-directory, and chosen during the location walk. Make ProxyPass
112 work correctly from within a LocationMatch. [Graham Leggett]
114 *) core: Fix segfault if per-module LogLevel is on virtual host
115 scope. PR 50117. [Stefan Fritsch]

120 *) mod_allowmethods: New module to deny certain HTTP methods without
121 interfering with authentication/authorization. [Paul Querna,
122 Igor Galić, Stefan Fritsch]
124 *) mod_ssl: Log certificate information and improve error message if client
125 cert verification fails. PR 50093, PR 50094. [Lassi Tuura <lat cern ch>,
128 *) htcacheclean: Teach htcacheclean to limit cache size by number of
129 inodes in addition to size of files. Prevents a cache disk from
130 running out of space when many small files are cached.
133 *) core: Rename MaxRequestsPerChild to MaxConnectionsPerChild, which
134 describes more accurately what the directive does. The old name
135 still works but logs a warning. [Stefan Fritsch]
137 *) mod_cache: Optionally serve stale data when a revalidation returns a
138 5xx response, controlled by the CacheStaleOnError directive.
141 *) htcacheclean: Allow the listing of valid URLs within the cache, with
142 the option to list entry metadata such as sizes and times. [Graham
145 *) mod_cache: correctly parse quoted strings in cache headers.
148 *) mod_cache: Allow control over the base URL of reverse proxied requests
149 using the CacheKeyBaseURL directive, so that the cache key can be
150 calculated from the endpoint URL instead of the server URL. [Graham
153 *) mod_cache: CacheLastModifiedFactor, CacheStoreNoStore, CacheStorePrivate,
154 CacheStoreExpired, CacheIgnoreNoLastMod, CacheDefaultExpire,
155 CacheMinExpire and CacheMaxExpire can be set per directory/location.
158 *) mod_disk_cache: CacheMaxFileSize, CacheMinFileSize, CacheReadSize and
159 CacheReadTime can be set per directory/location. [Graham Leggett]
161 *) core: Speed up config parsing if using a very large number of config
162 files. PR 50002 [andrew cloudaccess net]
164 *) mod_cache: Support the caching of HEAD requests. [Graham Leggett]
166 *) htcacheclean: Allow the option to round up file sizes to a given
167 block size, improving the accuracy of disk usage. [Graham Leggett]
169 *) mod_ssl: Add authz providers for use with mod_authz_core and its
170 RequireAny/RequireAll containers: 'ssl' (equivalent to SSLRequireSSL),
171 'ssl-verify-client' (for use with 'SSLVerifyClient optional'), and
172 'ssl-require' (expressions with same syntax as SSLRequire).
175 *) mod_ssl: Make the ssl expression parser thread-safe. It now requires
176 bison instead of yacc. [Stefan Fritsch]
178 *) mod_disk_cache: Change on-disk header file format to support the
179 link of the device/inode of the data file to the matching header
180 file, and to support the option of not writing a data file when
181 the data file is empty. [Graham Leggett]
183 *) core/mod_unique_id: Add generate_log_id hook to allow to use
184 the ID generated by mod_unique_id as error log ID for requests.
187 *) mod_cache: Make sure that we never allow a 304 Not Modified response
188 that we asked for to leak to the client should the 304 response be
189 uncacheable. PR45341 [Graham Leggett]
191 *) mod_cache: Add the cache_status hook to register the final cache
192 decision hit/miss/revalidate. Add optional support for an X-Cache
193 and/or an X-Cache-Detail header to add the cache status to the
194 response. PR48241 [Graham Leggett]
196 *) mod_authz_host: Add 'local' provider that matches connections originating
197 on the local host. PR 19938. [Stefan Fritsch]
199 *) Event MPM: Fix crash accessing pollset on worker thread when child
200 process is exiting. [Jeff Trawick]
202 *) core: For process invocation (cgi, fcgid, piped loggers and so forth)
203 pass the system library path (LD_LIBRARY_PATH or platform-specific
204 variables) along with the system PATH, by default. Both should be
205 overridden together as desired using PassEnv etc; see mod_env.
208 *) mod_cache: Introduce CacheStoreExpired, to allow administrators to
209 capture a stale backend response, perform If-Modified-Since requests
210 against the backend, and serving from the cache all 304 responses.
211 This restores pre-2.2.4 cache behavior. [William Rowe]
213 *) mod_rewrite: Introduce <=, >= string comparison operators, and integer
214 comparators -lt, -le, -eq, -ge, and -gt. To help bash users and drop
215 the ambiguity of the symlink test "-ltest", introduce -h or -L as
216 symlink test operators. [William Rowe]
218 *) mod_cache: Give the cache provider the opportunity to choose to cache
219 or not cache based on the buckets present in the brigade, such as the
220 presence of a FILE bucket.
223 *) mod_authz_core: Allow authz providers to check args while reading the
224 config and allow to cache parsed args. Move 'all' and 'env' authz
225 providers from mod_authz_host to mod_authz_core. Add 'method' authz
226 provider depending on the HTTP method. [Stefan Fritsch]
228 *) mod_include: Move the request_rec within mod_include to be
229 exposed within include_ctx_t. [Graham Leggett]
231 *) mod_include: Reinstate support for UTF-8 character sets by allowing a
232 variable being echoed or set to be decoded and then encoded as separate
233 steps. PR47686 [Graham Leggett]
235 *) mod_cache: Add a discrete commit_entity() provider function within the
236 mod_cache provider interface which is called to indicate to the
237 provider that caching is complete, giving the provider the opportunity
238 to commit temporary files permanently to the cache in an atomic
239 fashion. Replace the inconsistent use of error cleanups with a formal
240 set of pool cleanups attached to a subpool, which is destroyed on error.
243 *) mod_cache: Change the signature of the store_body() provider function
244 within the mod_cache provider interface to support an "in" brigade
245 and an "out" brigade instead of just a single input brigade. This
246 gives a cache provider the option to consume only part of the brigade
247 passed to it, rather than the whole brigade as was required before.
248 This fixes an out of memory and a request timeout condition that would
249 occur when the original document was a large file. Introduce
250 CacheReadSize and CacheReadTime directives to mod_disk_cache to control
251 the amount of data to attempt to cache at a time. [Graham Leggett]
253 *) core: Add ErrorLogFormat to allow configuring error log format, including
254 additional information that is logged once per connection or request. Add
255 error log IDs for connections and request to allow correlating error log
256 lines and the corresponding access log entry. [Stefan Fritsch]
258 *) core: Disable sendfile by default. [Stefan Fritsch]
260 *) mod_cache: Check the request to determine whether we are allowed
261 to return cached content at all, and respect a "Cache-Control:
262 no-cache" header from a client. Previously, "no-cache" would
263 behave like "max-age=0". [Graham Leggett]
265 *) mod_cache: Use a proper filter context to hold filter data instead
266 of misusing the per-request configuration. Fixes a segfault on trunk
267 when the normal handler is used. [Graham Leggett]
269 *) mod_cgid: Log a warning if the ScriptSock path is truncated because
270 it is too long. PR 49388. [Stefan Fritsch]
272 *) vhosts: Do not allow _default_ in NameVirtualHost, or mixing *
273 and non-* ports on NameVirtualHost, or multiple NameVirtualHost
274 directives for the same address:port, or NameVirtualHost
275 directives with no matching VirtualHosts, or multiple ip-based
276 VirtualHost sections for the same address:port. These were
277 previously accepted with a warning, but the behavior was
278 undefined. [Dan Poirier]
280 *) mod_remoteip: Fix a segfault when using mod_remoteip in conjunction with
281 Allow/Deny. PR 49838. [Andrew Skalski <voltara gmail.com>]
283 *) core: DirectoryMatch can now match on the end of line character ($),
284 and sub-directories of matched directories are no longer implicitly
285 matched. PR49809 [Eric Covener]
287 *) Regexps: introduce new higher-level regexp utility including parsing
288 and executing perl-style regexp ops (e.g s/foo/bar/i) and regexp memory
291 *) Proxy: support setting source address. PR 29404

371 request end time. [Rainer Jung]
373 Changes with Apache 2.3.6
375 *) SECURITY: CVE-2009-3555 (cve.mitre.org)
376 mod_ssl: Comprehensive fix of the TLS renegotiation prefix injection
377 attack when compiled against OpenSSL version 0.9.8m or later. Introduces
378 the 'SSLInsecureRenegotiation' directive to reopen this vulnerability
379 and offer unsafe legacy renegotiation with clients which do not yet
380 support the new secure renegotiation protocol, RFC 5746.

383 *) SECURITY: CVE-2009-3555 (cve.mitre.org)
384 mod_ssl: A partial fix for the TLS renegotiation prefix injection attack
385 by rejecting any client-initiated renegotiations. Forcibly disable
386 keepalive for the connection if there is any buffered data readable. Any
387 configuration which requires renegotiation for per-directory/location
388 access control is still vulnerable, unless using OpenSSL >= 0.9.8l.

409 *) mod_cache: Explicitly allow cache implementations to cache a 206 Partial
410 Response if they so choose to do so. Previously an attempt to cache a 206
411 was arbitrarily allowed if the response contained an Expires or
412 Cache-Control header, and arbitrarily denied if both headers were missing.

1268 subrequests to support message bodies. Make sure that safety
1269 checks within the core and within the proxy are not triggered
1270 when kept_body is present. This makes it possible to embed
1271 proxied POST requests within mod_include. [Graham Leggett]
1273 *) mod_auth_form: Make sure the input filter stack is properly set
1274 up before reading the login form. Make sure the kept body filter
1275 is correctly inserted to ensure the body can be read a second
1276 time safely should the authn be successful. [Graham Leggett,

1289 *) cache: retire ap_cache_cacheable_hdrs_out() which was used
1290 for both in- and out-put headers; and replace it by a single
1291 ap_cache_cacheable_headers() wrapped in a in- and out-put
1292 specific ap_cache_cacheable_headers_in()/out(). The latter
1293 which will also merge error and ensure content-type. To keep
1294 cache modules consistent with ease. This API change bumps
1295 up the minor MM by one [Dirk-Willem van Gulik].
1297 *) Move the KeptBodySize directive, kept_body filters and the
1298 ap_parse_request_body function out of the http module and into a
1299 new module called mod_request, reducing the size of the core.
1302 *) mod_dbd: Handle integer configuration directive parameters with a

1310 in using an HTML form, storing the credentials within mod_session.
1313 *) Add a function to the http filters that is able to parse an HTML
1314 form request with the type of application/x-www-form-urlencoded.

1320 *) mod_session_dbd: Add a session implementation capable of storing
1321 session information in a SQL database via the dbd interface. Useful
1322 for sites where session privacy is important. [Graham Leggett]

1325 of encrypting and decrypting sessions wherever they may be stored.

1327 browser. [Graham Leggett]
1329 *) mod_session_cookie: Add a session implementation capable of storing
1330 session information within cookies on the browser. Useful for high
1331 volume sites where server bound sessions are too resource intensive.
1334 *) mod_session: Add a generic session interface to unify the different
1335 attempts at saving persistent sessions across requests.
1338 *) core, authn/z: Avoid calling access control hooks for internal requests
1339 with configurations which match those of initial request. Revert to
1340 original behaviour (call access control hooks for internal requests
1341 with URIs different from initial request) if any access control hooks or
1342 providers are not registered as permitting this optimization.
