3 Changes with Apache 2.4.21
5 *) mod_http2: fixed a bug that caused mod_proxy_http2 to be called for window
6 updates on requests it had already reported done. Added synchronization
7 on early connection/stream close that lets ongoing requests safely drain
11 *) mod_http2: scoreboard updates that summarize the h2 session (and replace
12 the last request information) will only happen when the session is idle or
13 in shutdown/done phase. [Stefan Eissing]
15 *) mod_http2: new "bucket beam" technology to transport buckets across
16 threads without buffer copy. Delaying response start until flush or
17 enough body data has been accumulated. Overall significanlty smaller
18 memory footprint. [Stefan Eissing]
20 *) core: New CGIVar directive can configure REQUEST_URI to represent the
21 current URI being processed instead of always the original request.
24 *) scoreboard/status: Restore behavior of showing workers' previous Client,
25 VHost and Request values when idle, like in 2.4.18 and earlier.
27 *) mod_http2: r->protocol changed to "HTTP/2.0" (was "HTTP/2") as this will
28 give expected syntax in CGI's SERVER_PROTOCOL is more compatible with
29 existing major/minor handling. Fixes PR 59313.
31 *) mod_http2: disabling mmap for file buckets transport due to segmenation
32 faults when files change on the fly.
34 Changes with Apache 2.4.20
36 *) core: Do not read .htaccess if AllowOverride and AllowOverrideList
38 [Michael Schlenker <msc contact.de, Ruediger Pluem, Daniel Ruggeri]
40 *) mod_proxy_express: Fix possible use of DB handle after close. PR 59230.
41 [Petr <pgajdos suse.cz>]
43 *) core/util_script: relax alphanumeric filter of enviroment variable names
44 on Windows to allow '(' and ')' for passing PROGRAMFILES(X86) et.al.
45 unadulterated in 64 bit versions of Windows. PR 46751.
46 [John <john leineweb de>]
48 *) mod_http2: incrementing keepalives on each request started so that logging
49 %k gives increasing numbers per master http2 connection.
50 New documented variables in env, usable in custom log formats: H2_PUSH,
51 H2_PUSHED, H2_PUSHED_ON, H2_STREAM_ID and H2_STREAM_TAG.
54 *) mod_http2: more efficient passing of response bodies with less contention
55 and file bucket forwarding. [Stefan Eissing]
57 *) mod_http2: fix for missing score board updates on request count, fix for
58 memory leak on slave connection reuse. [Stefan Eissing]
60 *) mod_http2: Fix build on Windows from dsp files.
63 Changes with Apache 2.4.19
65 *) mod_include: Add variable DOCUMENT_ARGS, with the arguments to the
66 request for the SSI document. [Jeff Trawick]
68 *) mod_authz_host: Add a new "forward-dns" authorization type, not relying on
69 reverse DNS lookups. [Fabien]
71 *) mod_ssl: Add hooks to allow other modules to perform processing at
72 several stages of initialization and connection handling. See
73 mod_ssl_openssl.h. [Jeff Trawick]
75 *) mod_http2: disabling PUSH when client sends GOAWAY. Slave connections are
76 reused for several requests, improved performance and better memory use.
79 *) mod_rewrite: Don't implicitly URL-escape the original query string
80 when no substitution has changed it (like PR50447 but server context)
81 [Evgeny Kotkov <evgeny.kotkov visualsvn.com>]
83 *) mod_http2: fixes problem with wrong lifetime of file buckets on main
84 connection. [Stefan Eissing]
86 *) mod_http2: fixes incorrect denial of requests without :authority header.
89 *) mod_reqtimeout: Prevent long response times from triggering a timeout once
90 the request has been fully read. PR 59045. [Yann Ylavic]
92 *) ap_expr: expression support for variable HTTP2=on|off. [Stefan Eissing]
94 *) mod_http2: give control to async mpm for keepalive timeouts only when
95 no streams are open and even if only after 1 sec delay. Under load, event
96 mpm discards connections otherwise too quickly. [Stefan Eissing]
98 *) mod_ssl: Don't lose track of the SSL context if an unlikely failure occurs
99 in ssl_init_ssl_connection(). [Graham Leggett]
101 *) mod_rewrite: Add QSL|qslast flag to allow rewrites to files with
102 literal question marks in their names. PR 58777. [Eric Covener]
104 *) event: use pre_connection hook to properly initialize connection state for
105 slave connections. use protocol_switch hook to initialize server config
106 early based on SNI selected vhost.
109 *) hostname: Test and log useragent_host per-request across various modules,
110 including the scoreboard, expression and rewrite engines, setenvif,
111 authz_host, access_compat, custom logging, ssl and REMOTE_HOST variables.
112 PR55348 [William Rowe]
114 *) core: Track the useragent_host per-request when mod_remoteip or similar
115 modules track a per-request useragent_ip. Modules should be updated
116 to inquire for ap_get_useragent_host() in place of ap_get_remote_host().
119 *) core: fix a bug in <UnDefine ...> directive processing. When used, the last
120 <Define...>'ed variable was also withdrawn. PR 59019
123 *) mod_http2: Accept-Encoding is, when present on the initiating request,
124 added to push promises. This lets compressed content work in pushes.
125 by the client. [Stefan Eissing]
127 *) mod_http2: fixed possible read after free when streams were cancelled early
128 by the client. [Stefan Eissing]
130 *) mod_http2: fixed possible deadlock during connection shutdown. Thanks to
131 @FrankStolle for reporting and getting the necessary data.
134 *) mod_http2: fixed apr_uint64_t formatting in a log statement to user proper
135 APR def, thanks to @Sp1l.
137 *) mod_http2: number of worker threads allowed to a connection is adjusting
138 dynamically. Starting with 4, the number is doubled when streams can be
139 served without block on http/2 connection flow. The number is halfed, when
140 the server has to wait on client flow control grants.
141 This can happen with a maximum frequency of 5 times per second.
142 When a connection occupies too many workers, repeatable requests
143 (GET/HEAD/OPTIONS) are cancelled and placed back in the queue. Should that
144 not suffice and a stream is busy longer than the server timeout, the
145 connection will be aborted with error code ENHANCE_YOUR_CALM.
146 This does *not* limit the number of streams a client may open, rather the
147 number of server threads a connection might use.
150 *) mod_http2: allowing link header to specify multiple "rel" values,
151 space-separated inside a quoted string. Prohibiting push when Link
152 parameter "nopush" is present.
155 *) mod_http2: reworked connection state handling. Idle connections accept a
156 GOAWAY from the client without further reply. Otherwise the
157 module makes a best effort to send one last GOAWAY to the client.
159 *) mod_http2: the values from standard directives Timeout and KeepAliveTimeout
160 properly are applied to http/2 connections.
163 *) mod_http2: idle connections are returned to async mpms. new hook
164 "pre_close_connection" used to send GOAWAY frame when not already done.
165 Setting event mpm server config "by hand" for the main connection to
166 the correct negotiated server.
169 *) mod_http2: keep-alive blocking reads are done with 1 second timeouts to
170 check for MPM stopping. Will announce early GOAWAY and finish processing
171 open streams, then close.
174 *) mod_http2: bytes read/written on slave connections are reported via the
175 optional mod_logio functions. Fixes PR 58871.
177 *) prefork: Initialize the POD when running in ONE_PROCESS (or -X) mode to
178 avoid a crash. [Jan Kaluza, Yann Ylavic]
180 *) mod_ssl: When SSLVerify is disabled (NONE), don't force a renegotiation if
181 the SSLVerifyDepth applied with the default/handshaken vhost differs from
182 the one applicable with the finally selected vhost. [Yann Ylavic]
184 *) core: Ensure that httpd exits with an error status when the MPM fails
185 to run. [Yann Ylavic]
187 *) mod_ssl: Fix a possible memory leak on restart for custom [EC]DH params.
188 [Jan Kaluza, Yann Ylavic]
190 *) mod_ssl: Add SSLOCSPProxyURL to add the possibility to do all queries
191 to OCSP responders through a HTTP proxy. [Ruediger Pluem]
193 *) mod_proxy: Play/restore the TLS-SNI on new backend connections which
194 had to be issued because the remote closed the previous/reusable one
195 during idle (keep-alive) time. [Yann Ylavic]
197 *) mod_cache_socache: Fix a possible cached entity body corruption when it
198 is received from an origin server in multiple batches and forwarded by
199 mod_proxy. [Yann Ylavic]
201 *) core: Add expression support to SetHandler.
204 *) mod_remoteip: Prevent an external proxy from presenting an internal
205 proxy. PR 55962. [Mike Rumph]
207 *) core: Prevent a server crash in case of an invalid CONNECT request with
208 a custom error page for status code 400 that uses server side includes.
209 PR 58929 [Ruediger Pluem]
211 *) mod_ssl: handle TIMEOUT on empty SSL input as non-fatal, returning
212 APR_TIMEUP and preserving connection state for later retry.
215 *) mod_ssl: Save some TLS record (application data) fragmentations by
216 including the last and subsequent suitable buckets when coalescing.
219 *) mod_proxy_fcgi: Suppress HTTP error 503 and message 01075,
220 "Error dispatching request", when the cause appears to be
221 due to the client closing the connection.
222 PR58118. [Tobias Adolph <adolph lrz.de>]
224 *) mod_cgid: Message AH02550, failure to flush a response to the client,
225 is now logged at TRACE1 level to match the underlying core output filter
226 severity. [Eric Covener]
228 *) mime.types: add common extension "m4a" for MPEG 4 Audio.
229 PR 57895 [Dylan Millikin <dylan.millikin gmail.com>]
231 *) Added many log numbers to log statements that had none.
234 *) mod_log_config: Add GlobalLog to allow a globally defined log to
235 be inherited by virtual hosts that define a CustomLog.
238 *) mod_http2: connections how keep a "push diary" where hashes of already
239 pushed resources are kept. See directive H2PushDiarySize for managing this.
240 Push diaries can be initialized by clients via the "Cache-Digest" request
241 header. This carries a base64url encoded. compressed Golomb set as described
242 in https://datatracker.ietf.org/doc/draft-kazuho-h2-cache-digest/
243 Introduced a status handler for HTTP/2 connections, giving various counters
244 and statistics about the current connection, plus its cache digest value
245 in a JSON record. Not a replacement for more HTTP/2 in the server status.
247 <Location "/http2-status">
248 SetHandler http2-status
252 *) mod_http2: Fixed flushing of last GOAWAY frame. Previously, that frame
253 did not always reach the client, causing some to fail the next request.
254 Fixed calculation of last stream id accepted as described in rfc7540.
255 Reading in KEEPALIVE state now correctly shown in scoreboard.
256 Fixed possible race in connection shutdown after review by Ylavic.
257 Fixed segfault on connection shutdown, callback ran into a semi dismantled session.
260 *) mod_http2: Added support for experimental accept-push-policy draft
261 (https://tools.ietf.org/html/draft-ruellan-http-accept-push-policy-00). Clients
262 may now influence server pushes by sending accept-push-policy headers.
265 *) mod_http2: new r->subprocess_env variables HTTP2 and H2PUSH, set to "on"
266 when available for request.
269 *) mod_http2: fixed bug in input window size calculation by moving chunked
270 request body encoding into later stage of processing. Fixes PR 58825.
273 *) core: new hook "pre_close_connection" which is run before the lingering
274 close of connections is started. This gives protocol handlers one last
275 chance to use a connection before it goes down.
278 *) mod_status/scoreboard: showing connection protocol in new column, new
279 ap_update_child_status methods for updating server/description. mod_ssl
280 sets vhost negotiated by servername directly.
283 Changes with Apache 2.4.18
285 *) mod_ssl: for all ssl_engine_vars.c lookups, fall back to master connection
286 if conn_rec itself holds no valid SSLConnRec*. Fixes PR58666.
289 *) mod_http2: connection level window for flow control is set to protocol
290 maximum of 2GB-1, preventing window exhaustion when sending data on many
291 streams with higher cumulative window size.
292 Reducing write frequency unless push promises need to be flushed.
295 *) mod_http2: required minimum version of libnghttp2 is 1.2.1
298 *) mod_proxy_fdpass: Fix AH01153 error when using the default configuration.
299 In earlier version of httpd, you can explicitelly set the 'flusher' parameter
300 to 'flush' as a workaround. (i.e. flusher=flush)
301 Add documentation for the 'flusher' parameter when defining a proxy worker.
304 *) mod_ssl: For the "SSLStaplingReturnResponderErrors off" case, make sure
305 to only staple responses with certificate status "good". [Kaspar Brand]
307 *) mod_http2: new directive 'H2PushPriority' to allow priority specifications
308 on server pushed streams according to their content-type.
311 *) mod_http2: fixes crash on connection abort for a busy connection.
312 fixes crash on a request that did not produce any response.
315 *) mod_http2: trailers are sent after reponse body if set in request_rec
316 trailers_out before the end-of-request bucket is sent through the
317 output filters. [Stefan Eissing]
319 *) mod_http2: incoming trailers (headers after request body) are properly
320 forwarded to the processing engine. [Stefan Eissing]
322 *) mod_http2: new directive 'H2Push' to en-/disable HTTP/2 server
323 pushes a server/virtual host. Pushes are initiated by the presence
324 of 'Link:' headers with relation 'preload' on a response. [Stefan Eissing]
326 *) mod_http2: write performance of http2 improved for larger resources,
327 especially static files. [Stefan Eissing]
329 *) core: if the first HTTP/1.1 request on a connection goes to a server that
330 prefers different protocols, these protocols are announced in a Upgrade:
331 header on the response, mentioning the preferred protocols.
334 *) mod_http2: new directives 'H2TLSWarmUpSize' and 'H2TLSCoolDownSecs'
335 to control TLS record sizes during connection lifetime.
338 *) mod_http2: new directive 'H2ModernTLSOnly' to enforce security
339 requirements of RFC 7540 on TLS connections. [Stefan Eissing]
341 *) core: add ap_get_protocol_upgrades() to retrieve the list of protocols
342 that a client could possibly upgrade to. Use in first request on a
343 connection to announce protocol choices. [Stefan Eissing]
345 *) mod_http2: reworked deallocation on connection shutdown and worker
346 abort. Separate parent pool for all workers. worker threads are joined
347 on planned worker shutdown. [Yann Ylavic, Stefan Eissing]
349 *) mod_ssl: when receiving requests for other virtual hosts than the handshake
350 server, the SSL parameters are checked for equality. With equal
351 configuration, requests are passed for processing. Any change will trigger
352 the old behaviour of "421 Misdirected Request".
353 SSL now remembers the cipher suite that was used for the last handshake.
354 This is compared against for any vhost/directory cipher specification.
355 Detailed examination of renegotiation is only done when these do not
357 Renegotiation is 403ed when a master connection is present. Exact reason
358 is given additionally in a request note. [Stefan Eissing]
360 *) mod_ssl: Make the output filter more friendly with deferred write and
361 response pipelining. [Yann Ylavic, Joe Orton]
363 *) core: Fix scoreboard crash (SIGBUS) on hardware requiring strict 64bit
364 alignment (SPARC64, PPC64). [Yann Ylavic]
366 *) mod_cache: Accept HT (Horizontal Tab) when parsing cache related header
367 fields as described in RFC7230. [Christophe Jaillet]
369 *) core/util_script: making REDIRECT_URL a full URL is now opt-in
370 via new 'QualifyRedirectURL' directive.
372 *) core: Limit to ten the number of tolerated empty lines between request,
373 and consume them before the pipelining check to avoid possible response
374 delay when reading the next request without flushing. [Yann Ylavic]
376 *) mod_ssl: Extend expression parser registration to support ssl variables
377 in any expression using mod_rewrite syntax "%{SSL:VARNAME}" or function
378 syntax "ssl(VARNAME)". [Rainer Jung]
380 Changes with Apache 2.4.17
382 *) mod_http2: added donated HTTP/2 implementation via core module. Similar
383 configuration options to mod_ssl. [Stefan Eissing]
385 *) mod_proxy: don't recyle backend announced "Connection: close" connections
386 to avoid reusing it should the close be effective after some new request
387 is ready to be sent. [Yann Ylavic]
389 *) mod_substitute: Allow to configure the patterns merge order with the new
390 SubstituteInheritBefore on|off directive. PR 57641
391 [Marc.Stern <Marc.Stern approach.be>, Yann Ylavic, William Rowe]
393 *) mod_proxy: Fix ProxySourceAddress binding failure with AH00938.
394 PR 56687. [Arne de Bruijn <apache arbruijn.dds.nl>

397 and change the compiled-in default for SSL[Proxy]Protocol to "all -SSLv3",
398 in accordance with RFC 7568. PR 58349, PR 57120. [Kaspar Brand]
400 *) mod_ssl: append :!aNULL:!eNULL:!EXP to the cipher string settings,
401 instead of prepending !aNULL:!eNULL:!EXP: (as was the case in 2.4.7
402 and later). Enables support for configuring the SUITEB* cipher
403 strings introduced in OpenSSL 1.0.2. PR 58213. [Kaspar Brand]
405 *) mod_ssl: Add support for extracting the msUPN and dnsSRV forms
406 of subjectAltName entries of type "otherName" into
407 SSL_{CLIENT,SERVER}_SAN_OTHER_{msUPN,dnsSRV}_n environment
408 variables. Addresses PR 58020. [Jan Pazdziora <jpazdziora redhat.com>,
411 *) mod_logio: Fix logging of %^FB (time to first byte) on the first request on
412 an SSL connection. PR 58454.
413 [Konstantin J. Chernov <k.j.chernov gmail.com>]
415 *) mod_cache: r->err_headers_out is not merged into
416 r->headers when mod_cache is enabled and the response
417 is cached for the first time. [Edward Lu]
419 *) mod_slotmem_shm: Fix slots/SHM files names on restart for systems that
420 can't create new (clear) slots while previous children gracefully stopping
421 still use the old ones (e.g. Windows, OS2). mod_proxy_balancer failed to
422 restart whenever the number of configured balancers/members changed during
423 restart. PR 58024. [Yann Ylavic]
425 *) core/util_script: make REDIRECT_URL a full URL. PR 57785. [Nick Kew]

428 records for scalability. [Yingqi Lu <yingqi.lu@intel.com>,
429 Jeff Trawick, Jim Jagielski, Yann Ylavic]
431 *) mod_alias: Introduce expression parser support for Alias, ScriptAlias
432 and Redirect. Limit Redirect expressions to directory (Location) context
433 and redirect statuses (implicit or explicit).
434 [Graham Leggett, Yann Ylavic, Ruediger Pluem]
436 *) mod_proxy: Fix a race condition that caused a failed worker to be retried
437 before the retry period is over. [Ruediger Pluem]
439 *) mod_autoindex: Allow autoindexes when neither mod_dir nor mod_mime are
440 loaded. [Eric Covener]
442 *) mod_rewrite: Allow cookies set by mod_rewrite to contain ':' by accepting
443 ';' as an alternate separator. PR47241.
444 [<bugzilla schermesser com>, Eric Covener]
446 *) apxs: Add HTTPD_VERSION and HTTPD_MMN to the variables available with

3388 overridden together as desired using PassEnv etc; see mod_env.
3391 *) mod_cache: Introduce CacheStoreExpired, to allow administrators to
3392 capture a stale backend response, perform If-Modified-Since requests
3393 against the backend, and serving from the cache all 304 responses.
3394 This restores pre-2.2.4 cache behavior. [William Rowe]
3396 *) mod_rewrite: Introduce <=, >= string comparison operators, and integer
3397 comparators -lt, -le, -eq, -ge, and -gt. To help bash users and drop

3399 symlink test operators. [William Rowe]
3401 *) mod_cache: Give the cache provider the opportunity to choose to cache
3402 or not cache based on the buckets present in the brigade, such as the
3403 presence of a FILE bucket.

3407 config and allow to cache parsed args. Move 'all' and 'env' authz
3408 providers from mod_authz_host to mod_authz_core. Add 'method' authz
3409 provider depending on the HTTP method. [Stefan Fritsch]

3415 variable being echoed or set to be decoded and then encoded as separate
3416 steps. PR47686 [Graham Leggett]
3418 *) mod_cache: Add a discrete commit_entity() provider function within the
3419 mod_cache provider interface which is called to indicate to the
3420 provider that caching is complete, giving the provider the opportunity
3421 to commit temporary files permanently to the cache in an atomic
3422 fashion. Replace the inconsistent use of error cleanups with a formal
3423 set of pool cleanups attached to a subpool, which is destroyed on error.
3426 *) mod_cache: Change the signature of the store_body() provider function
3427 within the mod_cache provider interface to support an "in" brigade
3428 and an "out" brigade instead of just a single input brigade. This
3429 gives a cache provider the option to consume only part of the brigade
3430 passed to it, rather than the whole brigade as was required before.
3431 This fixes an out of memory and a request timeout condition that would
3432 occur when the original document was a large file. Introduce
3433 CacheReadSize and CacheReadTime directives to mod_disk_cache to control
3434 the amount of data to attempt to cache at a time. [Graham Leggett]
3436 *) core: Add ErrorLogFormat to allow configuring error log format, including
3437 additional information that is logged once per connection or request. Add
3438 error log IDs for connections and request to allow correlating error log
3439 lines and the corresponding access log entry. [Stefan Fritsch]
3441 *) core: Disable sendfile by default. [Stefan Fritsch]
3443 *) mod_cache: Check the request to determine whether we are allowed
3444 to return cached content at all, and respect a "Cache-Control:
3445 no-cache" header from a client. Previously, "no-cache" would
3446 behave like "max-age=0". [Graham Leggett]
3448 *) mod_cache: Use a proper filter context to hold filter data instead
3449 of misusing the per-request configuration. Fixes a segfault on trunk

4440 ap_setup_auth_internal(), which allows optional functions that just
4441 wrapped ap_list_provider_names() to be removed from authn/z modules.

4453 subrequests to support message bodies. Make sure that safety
4454 checks within the core and within the proxy are not triggered
4455 when kept_body is present. This makes it possible to embed
4456 proxied POST requests within mod_include. [Graham Leggett]

4515 session information within cookies on the browser. Useful for high
4516 volume sites where server bound sessions are too resource intensive.
4519 *) mod_session: Add a generic session interface to unify the different
4520 attempts at saving persistent sessions across requests.
4523 *) core, authn/z: Avoid calling access control hooks for internal requests
4524 with configurations which match those of initial request. Revert to
4525 original behaviour (call access control hooks for internal requests
4526 with URIs different from initial request) if any access control hooks or
4527 providers are not registered as permitting this optimization.
