3 Changes with Apache 2.4.19
4 *) core: Add expression support to SetHandler.
7 *) core: Prevent a server crash in case of an invalid CONNECT request with
8 a custom error page for status code 400 that uses server side includes.
9 PR 58929 [Ruediger Pluem]
11 *) mod_ssl: handle TIMEOUT on empty SSL input as non-fatal, returning
12 APR_TIMEUP and preserving connection state for later retry.
15 *) mod_ssl: Save some TLS record (application data) fragmentations by
16 including the last and subsequent suitable buckets when coalescing.
19 *) mod_proxy_fcgi: Suppress HTTP error 503 and message 01075,

35 *) Added many log numbers to log statements that had none.
38 *) mod_log_config: Add GlobalLog to allow a globally defined log to
39 be inherited by virtual hosts that define a CustomLog.
42 *) mod_http2: connection how keep a "push diary" where hashes of already
43 pushed resources are kept. See directive H2PushDiarySize for managing this.
44 Push diaries can be initialized by clients via the "Cache-Digest" request
45 header. This carries a base64url encoded. compressed Golomb set as described
46 in https://datatracker.ietf.org/doc/draft-kazuho-h2-cache-digest/
47 Introduced a status handler for HTTP/2 connections, giving various counters
48 and statistics about the current connection, plus its cache digest value
49 in a JSON record. Not a replacement for more HTTP/2 in the server status.
51 <Location "/http2-status">
52 SetHandler http2-status
56 *) mod_http2: Fixed flushing of last GOAWAY frame. Previously, that frame
57 did not always reach the client, causing some to fail the next request.

70 when available for request.
73 *) mod_http2: new config directives and the implementation behind
74 them: H2Timeout, H2KeepAliveTimeout, H2StreamTimeout. Documentation in

79 request body encoding into later stage of processing. Fixes PR 58825.
82 Changes with Apache 2.4.18
84 *) mod_ssl: for all ssl_engine_vars.c lookups, fall back to master connection
85 if conn_rec itself holds no valid SSLConnRec*. Fixes PR58666.
88 *) mod_http2: connection level window for flow control is set to protocol
89 maximum of 2GB-1, preventing window exhaustion when sending data on many
90 streams with higher cumulative window size.
91 Reducing write frequency unless push promises need to be flushed.
94 *) mod_http2: required minimum version of libnghttp2 is 1.2.1
97 *) mod_proxy_fdpass: Fix AH01153 error when using the default configuration.
98 In earlier version of httpd, you can explicitelly set the 'flusher' parameter
99 to 'flush' as a workaround. (i.e. flusher=flush)
100 Add documentation for the 'flusher' parameter when defining a proxy worker.
103 *) mod_ssl: For the "SSLStaplingReturnResponderErrors off" case, make sure
104 to only staple responses with certificate status "good". [Kaspar Brand]

107 on server pushed streams according to their content-type.
110 *) mod_http2: fixes crash on connection abort for a busy connection.
111 fixes crash on a request that did not produce any response.
114 *) mod_http2: trailers are sent after reponse body if set in request_rec
115 trailers_out before the end-of-request bucket is sent through the
116 output filters. [Stefan Eissing]
118 *) mod_http2: incoming trailers (headers after request body) are properly
119 forwarded to the processing engine. [Stefan Eissing]
121 *) mod_http2: new directive 'H2Push' to en-/disable HTTP/2 server
122 pushes a server/virtual host. Pushes are initiated by the presence
123 of 'Link:' headers with relation 'preload' on a response. [Stefan Eissing]
125 *) mod_http2: write performance of http2 improved for larger resources,
126 especially static files. [Stefan Eissing]
128 *) core: if the first HTTP/1.1 request on a connection goes to a server that
129 prefers different protocols, these protocols are announced in a Upgrade:
130 header on the response, mentioning the preferred protocols.

141 that a client could possibly upgrade to. Use in first request on a
142 connection to announce protocol choices. [Stefan Eissing]
144 *) mod_http2: reworked deallocation on connection shutdown and worker
145 abort. Separate parent pool for all workers. worker threads are joined
146 on planned worker shutdown. [Yann Ylavic, Stefan Eissing]
148 *) mod_ssl: when receiving requests for other virtual hosts than the handshake
149 server, the SSL parameters are checked for equality. With equal
150 configuration, requests are passed for processing. Any change will trigger
151 the old behaviour of "421 Misdirected Request".
152 SSL now remembers the cipher suite that was used for the last handshake.
153 This is compared against for any vhost/directory cipher specification.
154 Detailed examination of renegotiation is only done when these do not
156 Renegotiation is 403ed when a master connection is present. Exact reason
157 is given additionally in a request note. [Stefan Eissing]

169 via new 'QualifyRedirectURL' directive.
171 *) core: Limit to ten the number of tolerated empty lines between request,
172 and consume them before the pipelining check to avoid possible response
173 delay when reading the next request without flushing. [Yann Ylavic]
175 *) mod_ssl: Extend expression parser registration to support ssl variables
176 in any expression using mod_rewrite syntax "%{SSL:VARNAME}" or function
177 syntax "ssl(VARNAME)". [Rainer Jung]
179 Changes with Apache 2.4.17
181 *) mod_http2: added donated HTTP/2 implementation via core module. Similar
182 configuration options to mod_ssl. [Stefan Eissing]
184 *) mod_proxy: don't recyle backend announced "Connection: close" connections
185 to avoid reusing it should the close be effective after some new request
186 is ready to be sent. [Yann Ylavic]
188 *) mod_substitute: Allow to configure the patterns merge order with the new
189 SubstituteInheritBefore on|off directive. PR 57641

199 *) mod_ssl: append :!aNULL:!eNULL:!EXP to the cipher string settings,
200 instead of prepending !aNULL:!eNULL:!EXP: (as was the case in 2.4.7
201 and later). Enables support for configuring the SUITEB* cipher
202 strings introduced in OpenSSL 1.0.2. PR 58213. [Kaspar Brand]
204 *) mod_ssl: Add support for extracting the msUPN and dnsSRV forms
205 of subjectAltName entries of type "otherName" into
206 SSL_{CLIENT,SERVER}_SAN_OTHER_{msUPN,dnsSRV}_n environment
207 variables. Addresses PR 58020. [Jan Pazdziora <jpazdziora redhat.com>,
210 *) mod_logio: Fix logging of %^FB (time to first byte) on the first request on
211 an SSL connection. PR 58454.
212 [Konstantin J. Chernov <k.j.chernov gmail.com>]
214 *) mod_cache: r->err_headers_out is not merged into
215 r->headers when mod_cache is enabled and the response
216 is cached for the first time. [Edward Lu]

219 can't create new (clear) slots while previous children gracefully stopping
220 still use the old ones (e.g. Windows, OS2). mod_proxy_balancer failed to

3153 *) mod_disk_cache: Change on-disk header file format to support the
3154 link of the device/inode of the data file to the matching header
3155 file, and to support the option of not writing a data file when
3156 the data file is empty. [Graham Leggett]
3158 *) core/mod_unique_id: Add generate_log_id hook to allow to use

3163 that we asked for to leak to the client should the 304 response be
3164 uncacheable. PR45341 [Graham Leggett]
3166 *) mod_cache: Add the cache_status hook to register the final cache
3167 decision hit/miss/revalidate. Add optional support for an X-Cache
3168 and/or an X-Cache-Detail header to add the cache status to the
3169 response. PR48241 [Graham Leggett]
3171 *) mod_authz_host: Add 'local' provider that matches connections originating
3172 on the local host. PR 19938. [Stefan Fritsch]
3174 *) Event MPM: Fix crash accessing pollset on worker thread when child
3175 process is exiting. [Jeff Trawick]

3178 pass the system library path (LD_LIBRARY_PATH or platform-specific
3179 variables) along with the system PATH, by default. Both should be
3180 overridden together as desired using PassEnv etc; see mod_env.
3183 *) mod_cache: Introduce CacheStoreExpired, to allow administrators to
3184 capture a stale backend response, perform If-Modified-Since requests
3185 against the backend, and serving from the cache all 304 responses.
3186 This restores pre-2.2.4 cache behavior. [William Rowe]
3188 *) mod_rewrite: Introduce <=, >= string comparison operators, and integer
3189 comparators -lt, -le, -eq, -ge, and -gt. To help bash users and drop
3190 the ambiguity of the symlink test "-ltest", introduce -h or -L as
3191 symlink test operators. [William Rowe]
3193 *) mod_cache: Give the cache provider the opportunity to choose to cache
3194 or not cache based on the buckets present in the brigade, such as the
3195 presence of a FILE bucket.
3198 *) mod_authz_core: Allow authz providers to check args while reading the
3199 config and allow to cache parsed args. Move 'all' and 'env' authz
3200 providers from mod_authz_host to mod_authz_core. Add 'method' authz
3201 provider depending on the HTTP method. [Stefan Fritsch]
3203 *) mod_include: Move the request_rec within mod_include to be
3204 exposed within include_ctx_t. [Graham Leggett]
3206 *) mod_include: Reinstate support for UTF-8 character sets by allowing a
3207 variable being echoed or set to be decoded and then encoded as separate
3208 steps. PR47686 [Graham Leggett]
3210 *) mod_cache: Add a discrete commit_entity() provider function within the
3211 mod_cache provider interface which is called to indicate to the
3212 provider that caching is complete, giving the provider the opportunity
3213 to commit temporary files permanently to the cache in an atomic
3214 fashion. Replace the inconsistent use of error cleanups with a formal
3215 set of pool cleanups attached to a subpool, which is destroyed on error.
3218 *) mod_cache: Change the signature of the store_body() provider function
3219 within the mod_cache provider interface to support an "in" brigade
3220 and an "out" brigade instead of just a single input brigade. This
3221 gives a cache provider the option to consume only part of the brigade
3222 passed to it, rather than the whole brigade as was required before.
3223 This fixes an out of memory and a request timeout condition that would
3224 occur when the original document was a large file. Introduce
3225 CacheReadSize and CacheReadTime directives to mod_disk_cache to control
3226 the amount of data to attempt to cache at a time. [Graham Leggett]
3228 *) core: Add ErrorLogFormat to allow configuring error log format, including
3229 additional information that is logged once per connection or request. Add
3230 error log IDs for connections and request to allow correlating error log
3231 lines and the corresponding access log entry. [Stefan Fritsch]
3233 *) core: Disable sendfile by default. [Stefan Fritsch]
3235 *) mod_cache: Check the request to determine whether we are allowed
3236 to return cached content at all, and respect a "Cache-Control:
3237 no-cache" header from a client. Previously, "no-cache" would
3238 behave like "max-age=0". [Graham Leggett]

4379 *) mod_ssl: Fix TLS upgrade (RFC 2817) support. PR 41231. [Joe Orton]
4381 *) scoreboard: Correctly declare ap_time_process_request.
4382 PR 43789 [Tom Donovan <Tom.Donovan acm.org>]
4384 *) core; scoreboard: ap_get_scoreboard_worker(sbh) now takes the sbh member
4385 from the connection rec, ap_get_scoreboard_worker(proc, thread) will now
4386 provide the unusual legacy lookup. [William Rowe]
4388 *) mpm winnt: fix null pointer dereference
4389 PR 42572 [Davi Arnaut]
4391 *) mod_authnz_ldap, mod_authn_dbd: Tidy up the code to expose authn
4392 parameters to the environment. Improve portability to
4393 EBCDIC machines by using apr_toupper(). [Martin Kraemer]
4395 *) mod_ldap, mod_authnz_ldap: Add support for nested groups (i.e. the ability
4396 to authorize an authenticated user via a "require ldap-group X" directive
4397 where the user is not in group X, but is in a subgroup contained in X.

4400 *) mod_ssl: Add support for caching SSL Sessions in memcached. [Paul Querna]
4402 *) apxs: Enhance -q flag to print all known variables and their values
4403 when invoked without variable name(s).

4409 *) beos MPM: Create pmain pool and run modules' child_init hooks when
4410 entering ap_mpm_run(), then destroy pmain when exiting ap_mpm_run().
4413 *) netware MPM: Destroy pmain pool when exiting ap_mpm_run() so that
4414 cleanups registered in modules' child_init hooks are performed.
4417 *) Fix issue which could cause error messages to be written to access logs
4418 on Win32. PR 40476. [Tom Donovan <Tom.Donovan acm.org>]
4420 *) The LockFile directive, which specifies the location of
4421 the accept() mutex lockfile, is deprecated. Instead, the
4422 AcceptMutex directive now takes an optional lockfile
4423 location parameter, ala SSLMutex. [Jim Jagielski]
4425 *) mod_authn_dbd: Export any additional columns queried in the SQL select
4426 into the environment with the name AUTHENTICATE_<COLUMN>. This brings
4427 mod_authn_dbd behaviour in line with mod_authnz_ldap. [Graham Leggett]
4429 *) mod_dbd: Key the storage of prepared statements on the hex string
4430 value of server_rec, rather than the server name, as the server name
4431 may change (eg when the server name is set) at any time, causing
4432 weird behaviour in modules dependent on mod_dbd. [Graham Leggett]
4434 *) mod_proxy_fcgi: Added win32 build. [Mladen Turk]
4436 *) sendfile_nonblocking() takes the _brigade_ as an argument, gets
4437 the first bucket from the brigade, finds it not to be a FILE
4438 bucket and barfs. The fix is to pass a bucket rather than a brigade.

4441 *) mod_rewrite: support rewritemap by SQL query [Nick Kew]
4443 *) ap_get_server_version() has been removed. Third-party modules must
4444 now use ap_get_server_banner() or ap_get_server_description().
4447 *) All MPMs: Introduce a check_config phase between pre_config and
4448 open_logs, to allow modules to review interdependent configuration
4449 directive values and adjust them while messages can still be logged
4450 to the console. Handle relevant MPM directives during this phase
4451 and format messages for both the console and the error log, as
4452 appropriate. [Chris Darroch]
4454 *) core: Do not allow internal redirects like the DirectoryIndex of mod_dir
4455 to circumvent the symbolic link checks imposed by FollowSymLinks and
4456 SymLinksIfOwnerMatch. [Nick Kew, Ruediger Pluem, William Rowe]
4458 *) New SSLLogLevelDebugDump [ None (default) | IO (not bytes) | Bytes ]
4459 configures the I/O Dump of SSL traffic, when LogLevel is set to Debug.
4460 The default is none as this is far greater debugging resolution than

4487 *) mod_charset_lite: Remove Content-Length when output filter can
4488 invalidate it. Warn when input filter can invalidate it.
4491 *) Authz: Add the new module mod_authn_core that will provide common
4492 authn directives such as 'AuthType', 'AuthName'. Move the directives
4493 'AuthType' and 'AuthName' out of the core module and merge mod_authz_alias
4494 into mod_authn_core. [Brad Nicholes]
4496 *) Authz: Move the directives 'Order', 'Allow', 'Deny' and 'Satisfy'
4497 into the new module mod_access_compat which can be loaded to provide
4498 support for these directives.
4501 *) Authz: Move the 'Require' directive from the core module as well as
4502 add the directives '<SatisfyAll>', '<SatisfyOne>', '<RequireAlias>'
4503 and 'Reject' to mod_authz_core. The new directives introduce 'AND/OR'
4504 logic into the authorization processing. [Brad Nicholes]
4506 *) Authz: Add the new module mod_authz_core which acts as the
4507 authorization provider vector and contains common authz
4508 directives. [Brad Nicholes]
4510 *) Authz: Renamed mod_authz_dbm authz providers from 'group' and
4511 'file-group' to 'dbm-group' and 'dbm-file-group'. [Brad Nicholes]
4513 *) Authz: Added the new authz providers 'env', 'ip', 'host', 'all' to handle
4514 host-based access control provided by mod_authz_host and invoked
4515 through the 'Require' directive. [Brad Nicholes]
4517 *) Authz: Convert all of the authz modules from hook based to
4518 provider based. [Brad Nicholes]
4520 *) mod_cache: Add CacheMinExpire directive to set the minimum time in
4521 seconds to cache a document.

4527 [Christophe Jaillet <christophe.jaillet wanadoo.fr>]
4529 *) Asynchronous write completion for the Event MPM. [Brian Pane]
4531 *) Added an End-Of-Request bucket type. The logging of a request and
4532 the freeing of its pool are now done when the EOR bucket is destroyed.
4533 This has the effect of delaying the logging until right after the last
4534 of the response is sent; ap_core_output_filter() calls the access logger
4535 indirectly when it destroys the EOR bucket. [Brian Pane]
4537 *) Rewrite of logresolve support utility: IPv6 addresses are now supported
4538 and the format of statistical output has changed. [Colm MacCarthaigh]
4540 *) Rewrite of ap_coreoutput_filter to do nonblocking writes [Brian Pane]
4542 *) Added new connection states for handler and write completion
4545 *) mod_cgid: Refuse to work on Solaris 10 due to OS bugs. PR 34264.
4548 *) Teach mod_ssl to use arbitrary OIDs in an SSLRequire directive,
4549 allowing string-valued client certificate attributes to be used for
4550 access control, as in: SSLRequire "value" in OID("1.3.6.1.4.1.18060.1")
