2 Changes with Apache 2.5.1
4 *) mod_userdir: If several directories are given in a UserDir directive, only files
5 in the first existing one are checked. If the file is not found there, the
6 other possible directories are not checked. The doc clearly states that they
7 will be checked one by one, until a match is found or an external redirect is
11 *) mod_proxy: Fix a corner case where the ProxyPassReverseCookieDomain or
12 ProxyPassReverseCookiePath directive could fail to update correctly
13 'domain=' or 'path=' in the 'Set-Cookie' header. PR 61560.
16 *) mod_slotmem_shm: Add generation number to shm filename to fix races
17 with graceful restarts. PRs 62044 and 62308. [Jim Jagielski, Yann Ylavic]
19 *) mod_rewrite: Only create the global mutex used by "RewriteMap prg:" when
20 this type of map is present in the configuration. PR62311.
21 [Hank Ibell <hwibell gmail.com>]
23 *) mod_ldap: Abort on LDAP locking errors. [Eric Covener]
25 *) mod_ssl: Support loading certificates and private keys from the
26 PKCS#11 OpenSSL engine. [Anderson Sasaki <ansasaki redhat.com>,
29 *) mod_proxy_html: Fix variable interpolation and memory allocation failure
30 in ProxyHTMLURLMap. [Ewald Dieterich <ewald mailbox.org>]
32 *) core: In ONE_PROCESS/debug mode, cleanup everything when exiting.
35 *) mod_http2: restoring the v1.10.16 keepalive timeout behavioud of mod_http2 (to be verified).
38 *) mod_http2: adding an abort function to slave connections' pools, so out-of-memory
39 events lead to a control process abort, as on HTTP/1.x connections. [Stefan Eissing]
41 *) mod_http2: adding regular memory cleanup when transferring large response bodies. This
42 reduces memory footprint and avoids memory exhaustion when transferring large files
43 on 32-bit architectures. Fixes PR 62325. [Stefan Eissing]
45 *) http: LimitRequestBody applies to proxied requests. [Yann Ylavic]
47 *) mod_proxy_http: Fix response header thrown away after the previous one
48 was considered too large and truncated. PR 62196. [Yann Ylavic]
50 *) core: Add and handle AP_GETLINE_NOSPC_EOL flag for ap_getline() family
51 of functions to consume the end of line when the buffer is exhausted.
52 PR 62198. [Yann Ylavic]
54 *) mod_xml2enc: Fix forwarding of error metadata/responses. PR 62180.
55 [Micha Lenk <micha lenk.info>, Yann Ylavic]
57 *) mod_proxy_http: Add new worker parameter 'responsefieldsize' to
58 allow maximum HTTP response header size to be increased past 8192
59 bytes. PR62199. [Hank Ibell <hwibell gmail.com>]
61 *) core: Preserve the original HTTP request method in the '%<m' LogFormat
62 when an path-based ErrorDocument is used. PR 62186.
63 [Micha Lenk <micha lenk.info>]
65 *) mod_proxy_balancer: Add hot spare member type and corresponding flag (R). Hot spare members are
66 used as drop-in replacements for unusable workers in the same load balancer set. This differs
67 from hot standbys which are only used when all workers in a set are unusable. PR 61140. [Jim
70 *) mod_logio: Add LogIOTrackTTFU and %^FU logformat to log the time
71 difference between request start and last request body byte read (finished upload).
74 *) mod_ssl: add support for TLSv1.3 (tested with OpenSSL v1.1.1-pre4, other libs may
75 need more sugar). SSL(Proxy)CipherSuite now has an optional first parameter for the
76 protocol the ciphers are for.
77 Directive "SSLVerifyClient" now triggers certificate retrieval from the client (this
78 is not fully tested - but fails in similar fashion as in TLSv1.2 in my setups).
79 Verifying the client fails exactly the same for HTTP/2 connections for all SSL protocols,
80 as this would need to trigger the master connection thread - which we do not support
82 Renegotiation of ciphers is intentionally ignored for TLSv1.3 connections. "SSLCipherSuite"
83 does not allow to specify TLSv1.3 ciphers in a directory context (because it cannot work) and
84 TLSv1.2 or lower ciphers are not relevant, as cipher suites are completely separate.
85 This means there is a bit if a world split when simultaneously having TLSv1.2 and TLSv1.3
86 connections to the same server.
89 *) mod_http2: accurate reporting of h2 data input/output per request via mod_logio. Fixes
90 an issue where output sizes where counted n-times on reused slave connections. See
91 gituhub issue: https://github.com/icing/mod_h2/issues/158
94 *) mod_proxy: Do not restrict the maximum pool size for backend connections
95 any longer by the maximum number of threads per process and use a better
96 default if mod_http2 is loaded.
97 [Yann Ylavic, Ruediger Pluem, Stefan Eissing, Gregg Smith]
99 *) mod_ssl: Fix merging of proxy SSL context outside <Proxy> sections,
100 regression introduced in 2.4.30. PR 62232. [Rainer Jung, Yann Ylavic]
102 *) mod_ssl: proper checks for libressl 2.07/8 and its TLSv1_3 support, see PR 62236.
103 [Bernard Spil <brnrd@freebsd.org>]
105 *) mod_http2: on level trace2, log any unsuccessful HTTP/2 direct connection upgrade
106 with base64 encoding to unify its appearance in possible bug reports. [Stefan Eissing]
108 *) mod_cgi: Add CGIScriptTimeout to make mod_cgi's timeout per-directory and
109 independent of the core Timeout directive. PR 62229.
110 [Hank Ibell <hwibell gmail.com>]
112 *) mod_remoteip: Restore compatibility with APR 1.4 (apr_sockaddr_is_wildcard).
115 *) mod_ssl: heavily simplified SSLPolicy. No more user defines, no propxy policies,
116 just the basic "modern", "intermediate" and "old" as specified by Mozilla security.
119 *) mod_remoteip: make proxy-protocol work on slave connections, e.g. in HTTP/2
120 requests. See also https://github.com/roadrunner2/mod-proxy-protocol/issues/6
123 *) mod_md: fixes error in renew window calculation that may lead to mod_md running
124 watchdog in a tight loop until actual renewal becomes necessary. [Stefan Eissing]
126 *) mod_md: /.well-known/acme-challenge requests that cannot be answered for hostnames
127 outside the configured MDs are free to be answered by other handlers. This allows
128 co-existance between mod_md and other ACME clients on the same server (implements PR62189).
129 [Stefan Eissing, Arkadiusz Miskiewicz <arekm@maven.pl>]
131 *) mod_md: Fix compilation with OpenSSL before version 1.0.2. [Rainer Jung]
133 *) core: Create a conn_config_t structure to hold an extendable core config rather
134 than consuming the whole pointer with the connection socket. [Graham Leggett]
136 *) core: adding AP_DECLARE for ap_parse_vhost_addrs() and minor bumb mmn. Resolves
137 building mod_ssl on Windows. [Stefan Eissing, Gregg Smith]
139 *) mod_http2: discourage gzip/brotli content encoding on http2-status responses as
140 they are inserted into the reponse when filters are already done. [Stefan Eissing]
142 *) core: adding defines to allow interworking with honggfuzz without
143 further patches. [Stefan Eissing, Robert Swiecki]
145 *) mod_headers: 'RequestHeader set|edit|edit_r Content-Type X' could
146 inadvertently modify the Content-Type _response_ header. Applies to
147 Content-Type only and likely to only affect static file responses.
150 *) mod_cgi: Improve AH01215 messages to make it more clear that the message is
151 the CGI scripts stderr output. PR 61980. [Hank Ibell <hwibell gmail.com>]
153 *) mod_headers: Allow 'Header unset Content-Type' to remove the Content-Type
154 header. PR 61983. [Hank Ibell <hwibell gmail.com>]
156 *) mod_md v1.1.8: new configuration directive "MDBaseServer on|off" to allow/inhibit
157 management of the base server domains outside VirtualHosts. By default, this is "off",
158 e.g. mod_md will not manage certificates or perform https: redirections on the
159 base server. [Stefan Eissing]
161 *) core: Add "AcceptErrorsNonFatal" to allow ECONNREFUSED, ECONNABORTED, and
162 ECONNRESET during the client accept() to not trigger graceful shutdown of
163 the child process. [Eric Covener]
166 - MDMustStaple was unable to create the necessary OpenSSL OBJ identifier on some platforms,
167 possibly because this fails if the OID is already configured in ```openssl.cnf```, see
168 [here](https://github.com/openssl/openssl/issues/2795).
169 - Two memory leaks in cert issuer and alt-names lookup eliminated by Yann Ylavic.
170 - Changing MDMustStaple triggers certificate renewal.
171 - More verbosity when *not* handing out certificates, e.g. mod_ssl asks, but mod_md has no
172 idea what it is talking about. Some people report misbehaviour here.
173 - Re-enabled support for md_get_credentials() function that was used in older mod_ssl
174 patch, so that people with old patched servers get a chance to upgrade.
175 [Stefan Eissing, Yann Ylavic]
177 *) mod_susbtitute: Allow expressions in the subtitution, prefixed with expr=
180 *) mod_md: fixed mem pool usage for auto-added server names. Added
181 error logging of exact ACME response when challenges failed.
184 *) mod_dumpio: do nothing below log level TRACE7. [Yann Ylavic]
186 *) mod_md: reverses most of v1.0.5 optimization of post_config init, so that
187 mod_ssl can ask for certiticates without crashing. [Stefan Eissing]
189 *) mod_proxy: allow SSLProxyCheckPeer* usage for all proxy modules.
190 PR 61857. [Yann Ylavic]
192 *) mod_proxy_html: fix handling of <meta http-equiv> elements.
195 *) mod_md: fixed backward compatibility to old <ManagedDomain configuration.
196 Add higher level WARNING log when initial request to ACME server fails, mentioning
197 some advice. [Stefan Eissing]
199 *) mod_md: name change in configuration directives. The old names are still working
200 in this version, so you can safely upgrade. They will give warnings in the log and
201 will disappear in the immediate future. ManagedDomain is now MDomain,
202 <ManagedDomain> is now <MDomainSet>. [Stefan Eissing]
204 *) mod_ssl: renamed section <SSLPolicy to <SSLPolicyDefine. Fixed behaviour
205 for new server config merge flag. Denying global, only once used directives
206 inside a SSLPolicyDefine. [Stefan Eissing]
208 *) mod_auth_basic: Be less tolerant when parsing the credencial. Only spaces
209 should be accepted after the authorization scheme. \t are also tolerated.
212 *) mod_http2: fixed unfair scheduling when number of active connections
213 exceeded the scheduling fifo capacity. [Stefan Eissing]
215 *) core: Support zone/scope in IPv6 link-local addresses in Listen and
216 VirtualHost directives (requires APR 1.7.x or later). PR 59396. [Joe Orton]
218 *) mod_md: v1.0.5, restricting post_config dry run to be more silent and performing
219 only necessary work for mod_ssl to be also happy with the configuration.
222 *) mod_md: v1.0.4, removed the 'a2md' utility command from build. Only used in github
223 testing. Avoid problems with our build system that had problems after the latest
224 changes to make a clean initial build. Remove the windows a2md.dsp therefore also.
227 *) mod_ssl: Fail with 403 if the username for FakeBasicAuth mode
228 includes a colon character. PR 52644. [Joe Orton]
230 *) mod_md: v1.0.3, fixed various bugs in persisting job properties, so that status is
231 persisted accross child process changes and staging is reset on reloads. Changed
232 MDCertificateAgreement url checks. As long as the CA reports that the account has
233 an agreement, no further checking is done. Existing accounts need no changes when
234 a new agreement comes out. [Stefan Eissing]
236 *) mod_watchdog: Correct some log messages. [Rainer Jung]
238 *) mod_noloris: complete build setup. [Rainer Jung]
240 *) mod_md: fix static compilation. [Rainer Jung]
242 *) mod_md: fix compilation of helper binary a2md. [Rainer Jung]
244 *) core: fix pcre feature detection in configure when using pcre2. [Rainer Jung]
246 Changes with Apache 2.5.0-alpha
248 *) mod_md: v1.0.1, ServerName/Alias names from pure-http: virtual hosts are no longer
249 auto-added to a Managed Domain. Error counts of jobs are presisted. When the server
250 restarts (gracefully) any errored staging areas are purged to reset the signup/renewal
251 process. [Stefan Eissing]
253 *) mod_md: v1.0.0, new config directive 'MDNotifyCmd' to hook in a program when Managed
254 Domains have obtained/renewed their certificates successfully. [Stefan Eissing]
256 *) mod_md: v0.9.9, fix for applying challenge type based on available ports. [Stefan Eissing]
259 - Use of the new module flag
260 - Removed obsolete function from interface to mod_ssl.
261 - Fallback certificates has version set and no longer claims to be a CA. (re issue #32)
262 - MDRequireHttps now happens before any Redirect.
265 *) mod_ssl: unshare SSLSrvConfigRec instances between base server and virtual hosts. This avoids
266 overwrites of later initializattions (vhost_id), selective disables by "SSLEngine addr-list"
267 and certificate/key pickup from mod_md. [Stefan Eissing]
269 *) mod_md: v0.9.6: a "MDRequireHttps permament" configured domain automatically sends out
270 HSTS (rfc 6797) headers in https: responses. [Stefan Eissing]
272 *) mod_ssl: adding ssl_policies.h[.in] for policy cipher/protocol definitions. Use
273 update_policies.py to update manually from Mozilla JSON definitions at
274 https://statics.tls.security.mozilla.org/server-side-tls-conf.json
278 - New directive (srly: what do you expect at this point?) "MDMustStaple on|off" to control if
279 new certificates are requested with the OCSP Must Staple extension.
280 - Known limitation: when the server is configured to ditch and restart child processes, for example
281 after a certain number of connections/requests, the mod_md watchdog instance might migrate
282 to a new child process. Since not all its state is persisted, some messsages might appear a
283 second time in the logs.
284 - Adding checks when 'MDRequireHttps' is used. It is considered an error when 'MDPortMap 443:-'
285 is used - which negates that a https: port exists. Also, a warning is logged if no
286 VirtualHost can be found for a Managed Domain that has port 443 (or the mapped one) in
288 - New directive 'MDRequireHttps' for redirecting http: traffic to a Managed Domain, permanently
290 - Fix for using a fallback certificate on initial signup of a Managed Domain. Requires also
291 a changed mod_ssl patch (v5) to take effect.
292 - compatibility with libressl
295 *) mod_md: v0.9.2: new directive 'MDHttpProxy' to define a proxy for outgoing connection,
296 some minor bugfixes, twiddle the build system to avoid non-pic code generation.
300 - various fixes in MDRenewWindow handling when specifying percent. Serialization changed. If
301 someone already used percent configurations, it is advised to change these to a new value,
302 reload and change back to the wanted ones.
303 - various fixes in handling of MDPrivateKeys when specifying 2048 bits (the default) explicitly.
304 - mod_md version removed from top level md_store.json file. The store has its own format version
305 to facilitate upgrades.
309 Certificate provisioning from Let's Encrypt (and other ACME CAs) for mod_ssl virtual hosts.
312 *) mod_ssl: add SSLPolicy (define/use) and SSLProxyPolicy directives plus documentation. Add
313 core definitions for policies 'modern', 'intermediate' and 'old', as defined by Mozilla
314 in <https://wiki.mozilla.org/Security/Server_Side_TLS>. [Stefan Eissing]
316 *) mod_md: new module for managing domains across VirtualHosts with ACME protocol
317 implementation for automated certificate signup and renewal. Default CA is
318 the test area of Let's Encrypt right now, so certificates root will not be valid.
319 Will be switched to the real service endpoint rather soon. If you need it now,
320 configure 'MDCertificateAuthority https://acme-v01.api.letsencrypt.org/directory'.
323 *) mod_rewrite: Add 'RewriteOptions LongURLOptimization' to free memory
324 from each set of unmatched rewrite conditions.
327 *) Allow the argument to <IfFile>, <IfDefine>, <IfSection>, <IfDirective>,
328 and <IfModule> to be quoted. This is primarily for the benefit of
329 <IfFile>. [Eric Covener]
331 *) Introduce request taint checking framework to prevent privilege
332 hijacking through .htaccess. [Nick Kew]
334 *) Add <IfDirective> and <IfSection> directives. [Joe Orton]
336 *) When using mod_status with the Event MPM, report the number of requests
337 associated with an active connection in the "ACC" field. Previously
338 zero was always reported with this MPM. PR60647. [Eric Covener]
340 *) mod_remoteip: When overriding the useragent address from X-Forwarded-For,
341 zero out what had been initialized as the connection-level port. PR59931.
342 [Hank Ibell <hwibell gmail.com>]
344 *) mod_proxy_wstunnel: Reliably run before mod_proxy_http.
347 *) http: Allow unknown response status' lines returned in the form of
348 "HTTP/x.x xxx Status xxx". [Yann Ylavic]
350 *) core: Add <IfFile> configuration section to allow any file on disk to be
351 used as a conditional. [Edward Lu, Eric Covener]
353 *) mod_crypto: Add the all purpose crypto filters with support for HLS.
356 *) core: Drop an invalid Last-Modified header value coming
357 from a FCGI/CGI script instead of replacing it with Unix epoch.
358 Warn the users about Last-Modified header value replacements
359 and violations of the RFC.
360 [Yann Ylavic, Luca Toscano, William Rowe, Jacob Champion]
362 *) mod_dav: Allow other modules to become providers and add ACLs
364 [Jari Urpalainen <jari.urpalainen nokia.com>, Graham Leggett]
366 *) mod_dav: Add dav_begin_multistatus, dav_send_one_response,
367 dav_finish_multistatus, dav_send_multistatus, dav_handle_err,
368 dav_failed_proppatch, dav_success_proppatch to mod_dav.h.
369 [Jari Urpalainen <jari.urpalainen nokia.com>, Graham Leggett]
371 *) core: explicitly exclude 'h2' from protocols announced via an Upgrade:
372 header as commanded by http-wg. [Stefan Eissing]
374 *) mod_proxy_ajp: Add "secret" parameter to proxy workers to implement legacy
375 AJP13 authentication. PR 53098. [Dmitry A. Bakshaev <dab1818 gmail com>]
377 *) mpm: Generalise the ap_mpm_register_socket functions to accept pipes
378 or sockets. [Graham Leggett]
380 *) core: Extend support for setting aside data from the network input filter
381 to any connection or request input filter. [Graham Leggett]
383 *) core: Split ap_create_request() from ap_read_request(). [Graham Leggett]
385 *) mod_auth_digest: Fix compatibility with expression-based Authname. PR59039.
388 *) mpm: Add a complete_connection hook that confirms whether an MPM is allowed
389 to leave the WRITE_COMPLETION phase. Move filter code out of the MPMs.
392 *) mod_cache: Consider Cache-Control: s-maxage in expiration
393 calculations. [Eric Covener]
395 *) mod_cache: Allow caching of responses with an Expires header
396 in the past that also has Cache-Control: max-age or s-maxage.
397 PR55156. [Eric Covener]
399 *) mod_session: Introduce SessionExpiryUpdateInterval which allows to
400 configure the session/cookie expiry's update interval. PR 57300.
401 [Paul Spangler <paul.spangler ni.com>]
403 *) core: Extend support for asynchronous write completion from the
404 network filter to any connection or request filter. [Graham Leggett]
406 *) mod_auth_digest: remove AuthDigestEnableQueryStringHack which is no
407 more documented since dec 2012 (r1415960). [Christophe Jaillet]
409 *) mod_charset_lite: On EBCDIC platforms, make sure mod_charset_lite runs
410 after other resource-level filters. [Eric Covener]
412 *) http: Don't remove the Content-Length of zero from a HEAD response if
413 it comes from an origin server, module or script. [Yann Ylavic]
415 *) http: Add support for RFC2324/RFC7168. [Graham Leggett]
417 *) mod_authn_core: Add expression support to AuthName and AuthType.
420 *) suexec: Filter out the HTTP_PROXY environment variable because it is
421 treated as alias for http_proxy by some programs. [Stefan Fritsch]
423 *) mod_proxy_http: Don't establish or reuse a backend connection before pre-
424 fetching the request body, so to minimize the delay between it is supposed
425 to be alive and the first bytes sent: this is a best effort to prevent the
426 backend from closing because of idle or keepalive timeout in the meantime.
427 Also, handle a new "proxy-flushall" environment variable which allows to
428 flush any forwarded body data immediately. PR 56541+37920. [Yann Ylavic]
430 *) core: Define and UnDefine are no longer permitted in
431 directory context. Previously they would always be evaulated
432 as the configuration was read without regard for the directory
433 context. [Eric Covener]
435 *) config: For directives that do not expect any arguments, enforce
436 that none are specified in the configuration file.
437 [Joachim Zobel <jzobel heute-morgen.de>, Eric Covener]
439 *) mod_rewrite: Improve 'bad flag delimeters' startup error by showing
440 how the input was tokenized. PR 56528. [Edward Lu <Chaosed0 gmail.com>]
442 *) mod_proxy: Don't put non balancer-member workers in error state by
443 default for connection or 500/503 errors, and honor status=+I for
444 any error. PR 48388. [Yann Ylavic]
446 *) ap_expr: Add filemod function for checking file modification dates
449 *) mod_authnz_ldap: Resolve crashes with LDAP authz and non-LDAP authn since
450 r1608202. [Eric Covener]
452 *) apreq: Content-Length header should be always interpreted as a decimal.
453 Leading 0 could be erroneously considered as an octal value. PR 56598.
454 [Chris Card <ctcard hotmail com>]
456 *) mod_proxy: Now allow for 191 character worker names, with non-fatal
457 errors if name is truncated. PR53218. [Jim Jagielski]
459 *) mod_ssl: Add optional function "ssl_get_tls_cb" to allow support
460 for channel bindings. [Simo Sorce <simo redhat.com>]
462 *) mod_proxy_wstunnel: Concurrent websockets messages could be
463 lost or delayed with ProxyWebsocketAsync enabled.
464 [Edward Lu <Chaosed0 gmail.com>]
466 *) core, mod_info: Add compiled and loaded PCRE versions to version
467 number display. [Rainer Jung]
469 *) mod_authnz_ldap: Return LDAP connections to the pool before the handler
470 is run, instead of waiting until the end of the request. [Eric Covener]
472 *) mod_proxy_html: support automatic detection of doctype and processing
473 of FPIs. PR56285 [Micha Lenk <micha lenk info>, Nick Kew]
475 *) core: Add ap_mpm_resume_suspended() API to allow a suspended connection
477 [Artem <artemciy gmail.com>, Edward Lu <Chaosed0 gmail.com>]
479 *) core: Add ap_mpm_register_socket_callback_timeout() API. [Eric Covener]
481 *) mod_proxy_wstunnel: Honor ProxyWebsocketIdleTimeout in asynchronous
482 processing mode. [Eric Covener]
484 *) mod_authnz_ldap: Fail explicitly when the filter is too long. Remove
485 unnecessary apr_pstrdup() and strlen(). [Graham Leggett]
487 *) Add the ldap-search option to mod_authnz_ldap, allowing authorization
488 to be based on arbitrary expressions that do not include the username.
491 *) Add the ldap function to the expression API, allowing LDAP filters and
492 distinguished names based on expressions to be escaped correctly to
493 guard against LDAP injection. [Graham Leggett]
495 *) Add module mod_ssl_ct, which provides an implementation of Certificate
496 Transparency (RFC 6962) for httpd. [Jeff Trawick]
498 *) mod_proxy_wstunnel: Avoid sending error responses down an upgraded
499 websockets connection as it is being close down. [Eric Covener]
501 *) mod_proxy_wstunnel: Allow the administrator to cap the amount
502 of time a synchronous websockets connection stays idle with
503 ProxyWebsocketIdleTimeout. [Eric Covener]
505 *) mod_proxy_wstunnel: Change to opt-in for asynchronous support, adding
506 directives ProxyWebsocketAsync and ProxyWebsocketAsyncDelay.
509 *) mod_proxy_wstunnel: Stop leaking websockets backend connections under
510 event MPM (trunk-only). [Eric Covener]
512 *) mod_proxy_http: Add detach_backend hook (potentially usable
513 in other proxy scheme handlers). [Jeff Trawick]
515 *) mod_deflate: Add DeflateAlterETag to control how the ETag
516 is modified. The 'NoChange' parameter mimics 2.2.x behavior.
517 PR 45023, PR 39727. [Eric Covener]
519 *) mod_dir: Default to 2.2-like behavior and skip execution when method is
520 neither GET nor POST, such as for DAV requests. PR 54914. [Chris Darroch]
522 *) mod_rewrite: Rename the handler that does per-directory internal
523 redirects to "rewrite-redirect-handler" from "redirect-handler" so
524 it is less ambiguous and less likely to be reused. [Eric Covener]
526 *) mod_rewrite: Protect against looping with the [N] flag by enforcing a
527 default limit of 10000 iterations, and allowing each rule to change its
528 limit. [Eric Covener]
530 *) mod_ssl: Fix config merging of SSLOCSPEnable and SSLOCSPOverrideResponder.
533 *) Add HttpContentLengthHeadZero and HttpExpectStrict directives.
534 [Yehuda Sadeh <yehuda inktank com>, Justin Erenkrantz]
536 *) mod_ssl: Add -t -DDUMP_CA_CERTS option which dumps the filenames of all
537 configured SSL CA certificates to stdout the same way as DUMP_CERTS does.
540 *) mod_ssl: Don't flush when an EOS is received. Prepares mod_ssl
541 to support write completion. [Graham Leggett]
543 *) core: Add parse_errorlog_arg callback to ap_errorlog_provider
544 to allow providers to check the ErrorLog argument. [Jan Kaluza]
546 *) mod_cgid: Use the servers Timeout for each read from a CGI script,
547 allow override with new CGIDRequestTimeout directive. PR43494

550 *) core: ensure any abnormal exit is reported to stderr if it's a tty.
553 *) mod_lua: Let the Inter-VM get/set functions work with a global
554 shared memory pool instead of a per-process pool. [Daniel Gruno]
556 *) ldap: Support ldaps when using the Microsoft LDAP SDK.
557 PR 54626. [Jean-Frederic Clere]
559 *) mod_authnz_ldap: Change default value of AuthLDAPMaxSubGroupDepth to 0
560 to avoid performance problems when subgroups aren't in use. [Eric Covener]
562 *) mod_syslog: New module implementing syslog ap_error_log provider.
563 Previously, this code was part of core, now it's in separate module.
566 *) core: Add ap_errorlog_provider to make ErrorLog logging modular. Move
567 syslog support from core to new mod_syslog. [Jan Kaluza]
569 *) mod_status, mod_echo: Fix the display of client addresses.
570 They were truncated to 31 characters which is not enough for IPv6 addresses.
571 PR 54848 [Bernhard Schmidt <berni birkenwald de>]
573 *) core: merge AllowEncodedSlashes from the base configuration into
574 virtual hosts. [Eric Covener]
576 *) AIX: Install DSO's with "cp" instead of "install" in instdso.sh
579 *) mod_ldap: Don't keep retrying if a new LDAP connection times out.
582 *) mod_deflate: permit compilation of mod_deflate against a zlib that has
583 been configured with -D Z_PREFIX, which redefines the token "deflate".
586 *) mod_auth_digest: Use the secret when generating nonces in all cases and
587 not only when AuthName is used in .htaccess files (this change may cause
588 problems if used with round robin load balancers). Don't regenerate the
589 secret on graceful restarts. PR 54637 [Stefan Fritsch]
591 *) core: Stop the HTTP_IN filter from attempting to write error buckets
592 to the output filters, which is bogus in the proxy case. Create a
593 clean mapping from APR codes to HTTP status codes, and use it where
594 needed. [Graham Leggett]
596 *) mod_proxy: Ensure network errors detected by the proxy are returned as
597 504 Gateway Timout as opposed to 502 Bad Gateway, in order to be
598 compliant with RFC2616 14.9.4 Cache Revalidation and Reload Controls.
600 *) mod_dav: mod_dav overrides dav_fs response on PUT failure. PR 35981

604 *) mod_ldap: LDAP connections used for authentication were not respecting
605 LDAPConnectionPoolTimeout. PR 54587
607 *) core: Add option to add valgrind support. Use it to reduce false positive
608 warnings in mod_ssl. [Stefan Fritsch]
610 *) mod_authn_file, mod_authn_dbd, mod_authn_dbm, mod_authn_socache:
611 Cache the result of the most recent password hash verification for every
612 keep-alive connection. This saves some expensive calculations.
615 *) http: Remove support for Request-Range header sent by Navigator 2-3 and
616 MSIE 3. [Stefan Fritsch]
618 *) core, http: Extend HttpProtocol with an option to enforce stricter HTTP
619 conformance or to only log the found problems. [Stefan Fritsch]
623 *) core: Add LogLevelOverride directive that allows to override the
624 loglevel for clients from certain IPs. This also works for things
625 like the SSL handshake where <If> LogLevel ... </If> is evaluated
626 too late. [Stefan Fritsch]
628 *) core: Add new directive Warning to issue warnings from a configuration
629 file. Both Warning and Error now generate a timestamped log message.
632 *) ap_expr: Add SERVER_PROTOCOL_VERSION, ..._MAJOR, and ..._MINOR
633 variables. [Stefan Fritsch]
635 *) core: New directive HttpProtocol which allows to disable HTTP/0.9
636 support. [Stefan Fritsch]
638 *) mod_allowhandlers: New module to forbid specific handlers for specific
639 directories. [Stefan Fritsch]
641 *) mod_systemd: New module, for integration with systemd on Linux.
642 [Jan Kaluza <jkaluza redhat.com>]
644 *) WinNT MPM: Store pid and generation for each thread in scoreboard
645 to allow tracking of threads from exiting children via mod_status
646 or other such mechanisms. [Jeff Trawick]
648 *) The following now respect DefaultRuntimeDir/DEFAULT_REL_RUNTIMEDIR:
649 - APIs: ap_log_pid(), ap_remove_pid, ap_read_pid()
650 - mod_cache: thundering herd lock directory
651 - mod_lbmethod_heartbeat, mod_heartmonitor: heartbeat storage file
652 - mod_ldap: shared memory cache
653 - mod_socache_shmcb, mod_socache_dbm: shared memory or dbm for cache
656 *) suexec: Add --enable-suexec-capabilites support on Linux, to use
657 setuid/setgid capability bits rather than a setuid root binary.
660 *) suexec: Add support for logging to syslog as an alternative to logging
661 to a file; configure --without-suexec-logfile --with-suexec-syslog.
664 *) mod_ssl: Add support for TLS Next Protocol Negotiation. PR 52210.
665 [Matthew Steele <mdsteele google.com>]
667 *) cross-compile: allow to provide CC_FOR_BUILD so that gen_test_char will
668 be compiled by the build compiler instead of the host compiler.
669 Also set CC_FOR_BUILD to 'cc' when cross-compilation is detected.
670 PR 51257. [Guenter Knauf]
672 *) core: In maintainer mode, replace apr_palloc with a version that
673 initializes the allocated memory with non-zero values, except if
674 AP_DEBUG_NO_ALLOC_POISON is defined. [Stefan Fritsch]
676 *) mod_policy: Add a new testing module to help server administrators
677 enforce a configurable level of protocol compliance on their
678 servers and application servers behind theirs. [Graham Leggett]
680 *) mod_firehose: Add a new debugging module able to record traffic
681 passing through the server in such a way that connections and/or
682 requests be reconstructed and replayed. [Graham Leggett]
