10 [Michael Schlenker <msc contact.de, Ruediger Pluem, Daniel Ruggeri]
12 *) mod_proxy_express: Fix possible use of DB handle after close. PR 59230.
13 [Petr <pgajdos suse.cz>]

16 on Windows to allow '(' and ')' for passing PROGRAMFILES(X86) et.al.
17 unadulterated in 64 bit versions of Windows. PR 46751.
18 [John <john leineweb de>]
20 *) mod_http2: incrementing keepalives on each request started so that logging
21 %k gives increasing numbers per master http2 connection.
22 New documented variables in env, usable in custom log formats: H2_PUSH,
23 H2_PUSHED, H2_PUSHED_ON, H2_STREAM_ID and H2_STREAM_TAG.
26 *) mod_http2: more efficient passing of response bodies with less contention
27 and file bucket forwarding. [Stefan Eissing]
29 *) mod_http2: fix for missing score board updates on request count, fix for
30 memory leak on slave connection reuse. [Stefan Eissing]
32 *) mod_http2: Fix build on Windows from dsp files.
35 Changes with Apache 2.4.19
37 *) mod_include: Add variable DOCUMENT_ARGS, with the arguments to the
38 request for the SSI document. [Jeff Trawick]
40 *) mod_authz_host: Add a new "forward-dns" authorization type, not relying on
41 reverse DNS lookups. [Fabien]
43 *) mod_ssl: Add hooks to allow other modules to perform processing at
44 several stages of initialization and connection handling. See
45 mod_ssl_openssl.h. [Jeff Trawick]
47 *) mod_http2: disabling PUSH when client sends GOAWAY. Slave connections are
48 reused for several requests, improved performance and better memory use.
51 *) mod_rewrite: Don't implicitly URL-escape the original query string
52 when no substitution has changed it (like PR50447 but server context)
53 [Evgeny Kotkov <evgeny.kotkov visualsvn.com>]
55 *) mod_http2: fixes problem with wrong lifetime of file buckets on main
56 connection. [Stefan Eissing]
58 *) mod_http2: fixes incorrect denial of requests without :authority header.
61 *) mod_reqtimeout: Prevent long response times from triggering a timeout once
62 the request has been fully read. PR 59045. [Yann Ylavic]
64 *) ap_expr: expression support for variable HTTP2=on|off. [Stefan Eissing]
66 *) mod_http2: give control to async mpm for keepalive timeouts only when
67 no streams are open and even if only after 1 sec delay. Under load, event
68 mpm discards connections otherwise too quickly. [Stefan Eissing]
70 *) mod_ssl: Don't lose track of the SSL context if an unlikely failure occurs
71 in ssl_init_ssl_connection(). [Graham Leggett]
73 *) mod_rewrite: Add QSL|qslast flag to allow rewrites to files with
74 literal question marks in their names. PR 58777. [Eric Covener]
76 *) event: use pre_connection hook to properly initialize connection state for
77 slave connections. use protocol_switch hook to initialize server config
78 early based on SNI selected vhost.
81 *) hostname: Test and log useragent_host per-request across various modules,
82 including the scoreboard, expression and rewrite engines, setenvif,
83 authz_host, access_compat, custom logging, ssl and REMOTE_HOST variables.
84 PR55348 [William Rowe]
86 *) core: Track the useragent_host per-request when mod_remoteip or similar
87 modules track a per-request useragent_ip. Modules should be updated
88 to inquire for ap_get_useragent_host() in place of ap_get_remote_host().
91 *) core: fix a bug in <UnDefine ...> directive processing. When used, the last
92 <Define...>'ed variable was also withdrawn. PR 59019
95 *) mod_http2: Accept-Encoding is, when present on the initiating request,
96 added to push promises. This lets compressed content work in pushes.
97 by the client. [Stefan Eissing]
99 *) mod_http2: fixed possible read after free when streams were cancelled early
100 by the client. [Stefan Eissing]
102 *) mod_http2: fixed possible deadlock during connection shutdown. Thanks to
103 @FrankStolle for reporting and getting the necessary data.
106 *) mod_http2: fixed apr_uint64_t formatting in a log statement to user proper
107 APR def, thanks to @Sp1l.
109 *) mod_http2: number of worker threads allowed to a connection is adjusting
110 dynamically. Starting with 4, the number is doubled when streams can be
111 served without block on http/2 connection flow. The number is halfed, when
112 the server has to wait on client flow control grants.
113 This can happen with a maximum frequency of 5 times per second.
114 When a connection occupies too many workers, repeatable requests
115 (GET/HEAD/OPTIONS) are cancelled and placed back in the queue. Should that
116 not suffice and a stream is busy longer than the server timeout, the
117 connection will be aborted with error code ENHANCE_YOUR_CALM.
118 This does *not* limit the number of streams a client may open, rather the
119 number of server threads a connection might use.
122 *) mod_http2: allowing link header to specify multiple "rel" values,
123 space-separated inside a quoted string. Prohibiting push when Link
124 parameter "nopush" is present.
127 *) mod_http2: reworked connection state handling. Idle connections accept a
128 GOAWAY from the client without further reply. Otherwise the
129 module makes a best effort to send one last GOAWAY to the client.
131 *) mod_http2: the values from standard directives Timeout and KeepAliveTimeout
132 properly are applied to http/2 connections.
135 *) mod_http2: idle connections are returned to async mpms. new hook
136 "pre_close_connection" used to send GOAWAY frame when not already done.
137 Setting event mpm server config "by hand" for the main connection to
138 the correct negotiated server.
141 *) mod_http2: keep-alive blocking reads are done with 1 second timeouts to
142 check for MPM stopping. Will announce early GOAWAY and finish processing
143 open streams, then close.
146 *) mod_http2: bytes read/written on slave connections are reported via the
147 optional mod_logio functions. Fixes PR 58871.
149 *) prefork: Initialize the POD when running in ONE_PROCESS (or -X) mode to
150 avoid a crash. [Jan Kaluza, Yann Ylavic]
152 *) mod_ssl: When SSLVerify is disabled (NONE), don't force a renegotiation if
153 the SSLVerifyDepth applied with the default/handshaken vhost differs from
154 the one applicable with the finally selected vhost. [Yann Ylavic]
156 *) core: Ensure that httpd exits with an error status when the MPM fails
157 to run. [Yann Ylavic]
159 *) mod_ssl: Fix a possible memory leak on restart for custom [EC]DH params.
160 [Jan Kaluza, Yann Ylavic]
162 *) mod_ssl: Add SSLOCSPProxyURL to add the possibility to do all queries
163 to OCSP responders through a HTTP proxy. [Ruediger Pluem]
165 *) mod_proxy: Play/restore the TLS-SNI on new backend connections which
166 had to be issued because the remote closed the previous/reusable one
167 during idle (keep-alive) time. [Yann Ylavic]
169 *) mod_cache_socache: Fix a possible cached entity body corruption when it
170 is received from an origin server in multiple batches and forwarded by
171 mod_proxy. [Yann Ylavic]
173 *) core: Add expression support to SetHandler.
176 *) mod_remoteip: Prevent an external proxy from presenting an internal
177 proxy. PR 55962. [Mike Rumph]
179 *) core: Prevent a server crash in case of an invalid CONNECT request with
180 a custom error page for status code 400 that uses server side includes.
181 PR 58929 [Ruediger Pluem]
183 *) mod_ssl: handle TIMEOUT on empty SSL input as non-fatal, returning
184 APR_TIMEUP and preserving connection state for later retry.
187 *) mod_ssl: Save some TLS record (application data) fragmentations by
188 including the last and subsequent suitable buckets when coalescing.
191 *) mod_proxy_fcgi: Suppress HTTP error 503 and message 01075,
192 "Error dispatching request", when the cause appears to be
193 due to the client closing the connection.
194 PR58118. [Tobias Adolph <adolph lrz.de>]
196 *) mod_cgid: Message AH02550, failure to flush a response to the client,
197 is now logged at TRACE1 level to match the underlying core output filter
198 severity. [Eric Covener]
200 *) mime.types: add common extension "m4a" for MPEG 4 Audio.
201 PR 57895 [Dylan Millikin <dylan.millikin gmail.com>]
203 *) Added many log numbers to log statements that had none.
206 *) mod_log_config: Add GlobalLog to allow a globally defined log to
207 be inherited by virtual hosts that define a CustomLog.
210 *) mod_http2: connections how keep a "push diary" where hashes of already
211 pushed resources are kept. See directive H2PushDiarySize for managing this.
212 Push diaries can be initialized by clients via the "Cache-Digest" request
213 header. This carries a base64url encoded. compressed Golomb set as described
214 in https://datatracker.ietf.org/doc/draft-kazuho-h2-cache-digest/
215 Introduced a status handler for HTTP/2 connections, giving various counters
216 and statistics about the current connection, plus its cache digest value
217 in a JSON record. Not a replacement for more HTTP/2 in the server status.
219 <Location "/http2-status">
220 SetHandler http2-status
224 *) mod_http2: Fixed flushing of last GOAWAY frame. Previously, that frame
225 did not always reach the client, causing some to fail the next request.
226 Fixed calculation of last stream id accepted as described in rfc7540.
227 Reading in KEEPALIVE state now correctly shown in scoreboard.
228 Fixed possible race in connection shutdown after review by Ylavic.
229 Fixed segfault on connection shutdown, callback ran into a semi dismantled session.
232 *) mod_http2: Added support for experimental accept-push-policy draft
233 (https://tools.ietf.org/html/draft-ruellan-http-accept-push-policy-00). Clients
234 may now influence server pushes by sending accept-push-policy headers.
237 *) mod_http2: new r->subprocess_env variables HTTP2 and H2PUSH, set to "on"
238 when available for request.
241 *) mod_http2: fixed bug in input window size calculation by moving chunked
242 request body encoding into later stage of processing. Fixes PR 58825.
245 *) core: new hook "pre_close_connection" which is run before the lingering
246 close of connections is started. This gives protocol handlers one last
247 chance to use a connection before it goes down.
250 *) mod_status/scoreboard: showing connection protocol in new column, new
251 ap_update_child_status methods for updating server/description. mod_ssl
252 sets vhost negotiated by servername directly.
255 Changes with Apache 2.4.18
257 *) mod_ssl: for all ssl_engine_vars.c lookups, fall back to master connection
258 if conn_rec itself holds no valid SSLConnRec*. Fixes PR58666.
261 *) mod_http2: connection level window for flow control is set to protocol
262 maximum of 2GB-1, preventing window exhaustion when sending data on many
263 streams with higher cumulative window size.
264 Reducing write frequency unless push promises need to be flushed.
267 *) mod_http2: required minimum version of libnghttp2 is 1.2.1
270 *) mod_proxy_fdpass: Fix AH01153 error when using the default configuration.
271 In earlier version of httpd, you can explicitelly set the 'flusher' parameter
272 to 'flush' as a workaround. (i.e. flusher=flush)
273 Add documentation for the 'flusher' parameter when defining a proxy worker.
276 *) mod_ssl: For the "SSLStaplingReturnResponderErrors off" case, make sure
277 to only staple responses with certificate status "good". [Kaspar Brand]
279 *) mod_http2: new directive 'H2PushPriority' to allow priority specifications
280 on server pushed streams according to their content-type.
283 *) mod_http2: fixes crash on connection abort for a busy connection.
284 fixes crash on a request that did not produce any response.
287 *) mod_http2: trailers are sent after reponse body if set in request_rec
288 trailers_out before the end-of-request bucket is sent through the
289 output filters. [Stefan Eissing]
291 *) mod_http2: incoming trailers (headers after request body) are properly
292 forwarded to the processing engine. [Stefan Eissing]
294 *) mod_http2: new directive 'H2Push' to en-/disable HTTP/2 server
295 pushes a server/virtual host. Pushes are initiated by the presence
296 of 'Link:' headers with relation 'preload' on a response. [Stefan Eissing]
298 *) mod_http2: write performance of http2 improved for larger resources,
299 especially static files. [Stefan Eissing]
301 *) core: if the first HTTP/1.1 request on a connection goes to a server that
302 prefers different protocols, these protocols are announced in a Upgrade:
303 header on the response, mentioning the preferred protocols.
306 *) mod_http2: new directives 'H2TLSWarmUpSize' and 'H2TLSCoolDownSecs'
307 to control TLS record sizes during connection lifetime.
310 *) mod_http2: new directive 'H2ModernTLSOnly' to enforce security
311 requirements of RFC 7540 on TLS connections. [Stefan Eissing]
313 *) core: add ap_get_protocol_upgrades() to retrieve the list of protocols
314 that a client could possibly upgrade to. Use in first request on a
315 connection to announce protocol choices. [Stefan Eissing]
317 *) mod_http2: reworked deallocation on connection shutdown and worker
318 abort. Separate parent pool for all workers. worker threads are joined
319 on planned worker shutdown. [Yann Ylavic, Stefan Eissing]
321 *) mod_ssl: when receiving requests for other virtual hosts than the handshake
322 server, the SSL parameters are checked for equality. With equal
323 configuration, requests are passed for processing. Any change will trigger
324 the old behaviour of "421 Misdirected Request".
325 SSL now remembers the cipher suite that was used for the last handshake.
326 This is compared against for any vhost/directory cipher specification.
327 Detailed examination of renegotiation is only done when these do not
329 Renegotiation is 403ed when a master connection is present. Exact reason
330 is given additionally in a request note. [Stefan Eissing]
332 *) mod_ssl: Make the output filter more friendly with deferred write and
333 response pipelining. [Yann Ylavic, Joe Orton]
335 *) core: Fix scoreboard crash (SIGBUS) on hardware requiring strict 64bit
336 alignment (SPARC64, PPC64). [Yann Ylavic]
338 *) mod_cache: Accept HT (Horizontal Tab) when parsing cache related header
339 fields as described in RFC7230. [Christophe Jaillet]
341 *) core/util_script: making REDIRECT_URL a full URL is now opt-in
342 via new 'QualifyRedirectURL' directive.
344 *) core: Limit to ten the number of tolerated empty lines between request,
345 and consume them before the pipelining check to avoid possible response
346 delay when reading the next request without flushing. [Yann Ylavic]
348 *) mod_ssl: Extend expression parser registration to support ssl variables
349 in any expression using mod_rewrite syntax "%{SSL:VARNAME}" or function
350 syntax "ssl(VARNAME)". [Rainer Jung]
352 Changes with Apache 2.4.17
354 *) mod_http2: added donated HTTP/2 implementation via core module. Similar
355 configuration options to mod_ssl. [Stefan Eissing]
357 *) mod_proxy: don't recyle backend announced "Connection: close" connections
358 to avoid reusing it should the close be effective after some new request
359 is ready to be sent. [Yann Ylavic]
361 *) mod_substitute: Allow to configure the patterns merge order with the new
362 SubstituteInheritBefore on|off directive. PR 57641

372 *) mod_ssl: append :!aNULL:!eNULL:!EXP to the cipher string settings,
373 instead of prepending !aNULL:!eNULL:!EXP: (as was the case in 2.4.7
374 and later). Enables support for configuring the SUITEB* cipher
375 strings introduced in OpenSSL 1.0.2. PR 58213. [Kaspar Brand]
377 *) mod_ssl: Add support for extracting the msUPN and dnsSRV forms
378 of subjectAltName entries of type "otherName" into
379 SSL_{CLIENT,SERVER}_SAN_OTHER_{msUPN,dnsSRV}_n environment
380 variables. Addresses PR 58020. [Jan Pazdziora <jpazdziora redhat.com>,
383 *) mod_logio: Fix logging of %^FB (time to first byte) on the first request on
384 an SSL connection. PR 58454.
385 [Konstantin J. Chernov <k.j.chernov gmail.com>]
387 *) mod_cache: r->err_headers_out is not merged into
388 r->headers when mod_cache is enabled and the response
389 is cached for the first time. [Edward Lu]
391 *) mod_slotmem_shm: Fix slots/SHM files names on restart for systems that
392 can't create new (clear) slots while previous children gracefully stopping
393 still use the old ones (e.g. Windows, OS2). mod_proxy_balancer failed to
394 restart whenever the number of configured balancers/members changed during
395 restart. PR 58024. [Yann Ylavic]
397 *) core/util_script: make REDIRECT_URL a full URL. PR 57785. [Nick Kew]

400 records for scalability. [Yingqi Lu <yingqi.lu@intel.com>,
401 Jeff Trawick, Jim Jagielski, Yann Ylavic]
403 *) mod_alias: Introduce expression parser support for Alias, ScriptAlias
404 and Redirect. Limit Redirect expressions to directory (Location) context
405 and redirect statuses (implicit or explicit).
406 [Graham Leggett, Yann Ylavic, Ruediger Pluem]
408 *) mod_proxy: Fix a race condition that caused a failed worker to be retried
409 before the retry period is over. [Ruediger Pluem]
411 *) mod_autoindex: Allow autoindexes when neither mod_dir nor mod_mime are
412 loaded. [Eric Covener]
414 *) mod_rewrite: Allow cookies set by mod_rewrite to contain ':' by accepting
415 ';' as an alternate separator. PR47241.
416 [<bugzilla schermesser com>, Eric Covener]

427 *) mod_socache_memcache: Add the 'MemcacheConnTTL' directive to control how
428 long to keep idle connections with the memcache server(s).
429 Change default value from 600 usec (!) to 15 sec. PR 58091

502 the OCSP response for a different certificate. mod_ssl has an additional
503 global mutex, "ssl-stapling-refresh". PR 57131 (partial fix).
506 *) mod_authz_dbm: Fix crashes when "dbm-file-group" is used and

3086 *) mod_authn_socache: change directive name from AuthnCacheProvider
3087 to AuthnCacheProvideFor. The term "provider" is overloaded in
3088 this module, and we should avoid confusion between the provider
3089 of a backend (AuthnCacheSOCache) and the authn provider(s) for
3090 which this module provides cacheing (AuthnCacheProvideFor).
3093 *) mod_proxy_http: Allocate the fake backend request from a child pool

3388 *) mod_cache: Add a discrete commit_entity() provider function within the
3389 mod_cache provider interface which is called to indicate to the
3390 provider that caching is complete, giving the provider the opportunity
3391 to commit temporary files permanently to the cache in an atomic
3392 fashion. Replace the inconsistent use of error cleanups with a formal
3393 set of pool cleanups attached to a subpool, which is destroyed on error.

3397 within the mod_cache provider interface to support an "in" brigade
3398 and an "out" brigade instead of just a single input brigade. This
3399 gives a cache provider the option to consume only part of the brigade
3400 passed to it, rather than the whole brigade as was required before.
3401 This fixes an out of memory and a request timeout condition that would
3402 occur when the original document was a large file. Introduce
3403 CacheReadSize and CacheReadTime directives to mod_disk_cache to control
3404 the amount of data to attempt to cache at a time. [Graham Leggett]

4423 subrequests to support message bodies. Make sure that safety
4424 checks within the core and within the proxy are not triggered
4425 when kept_body is present. This makes it possible to embed
4426 proxied POST requests within mod_include. [Graham Leggett]

4495 original behaviour (call access control hooks for internal requests
4496 with URIs different from initial request) if any access control hooks or
