11 to allow providers to check the ErrorLog argument. [Jan Kaluza]
13 *) core: Detect incomplete body in HTTP input filter and return
14 APR_INCOMPLETE. PR 55475 [Yann Ylavic <ylavic dev gmail com>]

21 PR 54946. [Rainer Jung]
23 *) core: ensure any abnormal exit is reported to stderr if it's a tty.
26 *) mod_proxy: Added support for unix domain sockets as the
27 backend server endpoint [Jim Jagielski, Blaise Tarr
28 <blaise tarr gmail com>]
30 *) mod_authn_socache: Support optional initialization arguments for
31 socache providers. [Chris Darroch]

36 *) mod_session: After parsing the value of the header specified by the
37 SessionHeader directive, remove the value from the response. PR 55279.
40 *) mod_auth_form: Make sure the optional functions are loaded even when
41 the AuthFormProvider isn't specified. [Graham Leggett]
43 *) mod_ssl: Improve handling of ephemeral DH and ECDH keys by
44 allowing custom parameters to be configured via SSLCertificateFile,
45 and by adding standardized DH parameters for 1024/2048/3072/4096 bits.
46 Unless custom parameters are configured, the standardized parameters
47 are applied based on the certificate's RSA/DSA key size. [Kaspar Brand]
49 *) mod_ssl, configure: Require OpenSSL 0.9.8a or later. [Kaspar Brand]
51 *) mod_lua: Let the Inter-VM get/set functions work with a global

61 keys, and unconditionally disable aNULL, eNULL and EXP ciphers
62 (not overridable via SSLCipherSuite). [Kaspar Brand]
64 *) mod_authnz_ldap: Change default value of AuthLDAPMaxSubGroupDepth to 0
65 to avoid performance problems when subgroups aren't in use. [Eric Covener]
67 *) mod_syslog: New module implementing syslog ap_error_log provider.
68 Previously, this code was part of core, now it's in separate module.
71 *) core: Add ap_errorlog_provider to make ErrorLog logging modular. Move
72 syslog support from core to new mod_syslog. [Jan Kaluza]
74 *) mod_proxy_fcgi: Handle reading protocol data that is split between
75 packets. [Jeff Trawick]
77 *) mod_proxy_fcgi: Remove 64K limit on encoded length of all envvars.

79 omitted. [Jeff Trawick]
81 *) core: draft-ietf-httpbis-p1-messaging-23 corrections regarding
82 TE/CL conflicts. [Yann Ylavic <ylavic.dev gmail com>, Jim Jagielski]
84 *) mod_proxy_fcgi: Use apr_socket_timeout_get instead of hard-coded
85 30 seconds timeout. [Jan Kaluza]
87 *) WinNT MPM: If ap_run_pre_connection() fails or sets c->aborted, don't
88 save the socket for reuse by the next worker as if it were an
89 APR_SO_DISCONNECTED socket. Restores 2.2 behavior. [Eric Covener]
91 *) mod_cache: Avoid a crash with strcmp() when the hostname is not provided.

100 *) mod_lua: Add a logging hook for modifying/skipping logs. [Daniel Gruno]
102 *) mod_status, mod_echo: Fix the display of client addresses.
103 They were truncated to 31 characters which is not enough for IPv6 addresses.
104 PR 54848 [Bernhard Schmidt <berni birkenwald de>]
106 *) mod_lua: If the first yield() of a LuaOutputFilter returns a string, it should
107 be prefixed to the response as documented. [Eric Covener]
109 *) mod_lua: Remove ETAG, Content-Length, and Content-MD5 when a LuaOutputFilter
110 is configured without mod_filter. [Eric Covener]
112 *) mod_lua: Register LuaOutputFilter scripts as changing the content and
113 content-length by default, when run my mod_filter. Previously,
114 growing or shrinking a response that started with Content-Length set
115 would require mod_filter and FilterProtocol change=yes. [Eric Covnener]
117 *) mod_lua: Return a 500 error if a LuaHook* script doesn't return a
118 numeric return code. [Eric Covener]
120 *) mod_authnz_fcgi: New module to enable FastCGI authorizer
121 applications to authenticate and/or authorize clients.
124 *) core: Add util_fcgi.h and associated definitions and support
125 routines for FastCGI, based largely on mod_proxy_fcgi.
128 *) core: Add ap_log_data(), ap_log_rdata(), etc. for logging buffers.
131 *) mod_unique_id: Use output of the PRNG rather than IP address and
132 pid, avoiding sleep() call and possible DNS issues at startup,
133 plus improving randomness for IPv6-only hosts.
134 [Jan Kaluza <jkaluza redhat.com>]
136 *) mod_authnz_ldap: Support primitive LDAP servers that do not accept
137 filters, such as "SDBM-backed LDAP" on z/OS, by allowing a special
138 filter "none" to be specified in AuthLDAPURL. [Eric Covener]
140 *) mod_file_cache: mod_file_cache should be able to serve files that
141 haven't had a Content-Type set via e.g. mod_mime. [Eric Covener]
143 *) core: merge AllowEncodedSlashes from the base configuration into
144 virtual hosts. [Eric Covener]
146 *) AIX: Install DSO's with "cp" instead of "install" in instdso.sh
149 *) mod_ldap: Don't keep retrying if a new LDAP connection times out.
152 *) mod_deflate: permit compilation of mod_deflate against a zlib that has
153 been configured with -D Z_PREFIX, which redefines the token "deflate".
156 *) mod_socache_shmcb.c: Remove arbitrary restriction on shared memory size
157 previously limited to 64MB. [Jens Låås <jelaas gmail.com>]
159 *) mod_auth_digest: Use the secret when generating nonces in all cases and
160 not only when AuthName is used in .htaccess files (this change may cause
161 problems if used with round robin load balancers). Don't regenerate the
162 secret on graceful restarts. PR 54637 [Stefan Fritsch]
164 *) core: Remove apr_brigade_flatten(), buffering and duplicated code
165 from the HTTP_IN filter, parse chunks in a single pass with zero copy.
166 Reduce memory usage by 48 bytes per request. [Graham Leggett]
168 *) core: Stop the HTTP_IN filter from attempting to write error buckets
169 to the output filters, which is bogus in the proxy case. Create a
170 clean mapping from APR codes to HTTP status codes, and use it where
171 needed. [Graham Leggett]
173 *) mod_proxy: Ensure network errors detected by the proxy are returned as
174 504 Gateway Timout as opposed to 502 Bad Gateway, in order to be
175 compliant with RFC2616 14.9.4 Cache Revalidation and Reload Controls.
177 *) mod_dav: mod_dav overrides dav_fs response on PUT failure. PR 35981
178 [Basant Kumar Kukreja <basant.kukreja sun.com>, Alejandro Alvarez
179 <alejandro.alvarez.ayllon cern.ch>]
181 *) core, mod_ssl: Enable the ability for a module to reverse the sense of
182 a poll event from a read to a write or vice versa. This is a step on
183 the way to allow mod_ssl taking full advantage of the event MPM.
186 *) mod_ldap: LDAP connections used for authentication were not respecting
187 LDAPConnectionPoolTimeout. PR 54587
189 *) core: ap_rgetline_core now pulls from r->proto_input_filters.
191 *) mod_proxy_html: process parsed comments immediately.
192 Fixes bug where parsed comments may be lost. [Nick Kew]
194 *) mod_proxy_html: introduce doctype for HTML 5 [Nick Kew]
196 *) mod_proxy_html: fix typo-bug processing "strict" vs "transitional"
197 HTML/XHTML [Nick Kew]
199 *) core: Add option to add valgrind support. Use it to reduce false positive
200 warnings in mod_ssl. [Stefan Fritsch]
202 *) mod_authn_file, mod_authn_dbd, mod_authn_dbm, mod_authn_socache:
203 Cache the result of the most recent password hash verification for every
204 keep-alive connection. This saves some expensive calculations.
207 *) http: Remove support for Request-Range header sent by Navigator 2-3 and
208 MSIE 3. [Stefan Fritsch]
210 *) core, http: Extend HttpProtocol with an option to enforce stricter HTTP
211 conformance or to only log the found problems. [Stefan Fritsch]
213 *) core: Correctly parse an IPv6 literal host specification in an absolute
214 URL in the request line. [Stefan Fritsch]
216 *) mod_ssl: Add support for OpenSSL configuration commands [Stephen Henson]
220 *) core: Add LogLevelOverride directive that allows to override the
221 loglevel for clients from certain IPs. This also works for things
222 like the SSL handshake where <If> LogLevel ... </If> is evaluated
223 too late. [Stefan Fritsch]
225 *) core: Add new directive Warning to issue warnings from a configuration
226 file. Both Warning and Error now generate a timestamped log message.
229 *) ap_expr: Add SERVER_PROTOCOL_VERSION, ..._MAJOR, and ..._MINOR
230 variables. [Stefan Fritsch]
232 *) core: New directive RegisterHttpMethod for registering non-standard
233 HTTP methods. [Stefan Fritsch]
235 *) core: New directive HttpProtocol which allows to disable HTTP/0.9
236 support. [Stefan Fritsch]
238 *) mod_allowhandlers: New module to forbid specific handlers for specific
239 directories. [Stefan Fritsch]
241 *) mod_systemd: New module, for integration with systemd on Linux.
242 [Jan Kaluza <jkaluza redhat.com>]
244 *) WinNT MPM: Store pid and generation for each thread in scoreboard
245 to allow tracking of threads from exiting children via mod_status
246 or other such mechanisms. [Jeff Trawick]
248 *) The following now respect DefaultRuntimeDir/DEFAULT_REL_RUNTIMEDIR:
249 - APIs: ap_log_pid(), ap_remove_pid, ap_read_pid()
250 - core: the scoreboard (ScoreBoardFile), pid file (PidFile), and
252 - mod_cache: thundering herd lock directory
253 - mod_lbmethod_heartbeat, mod_heartmonitor: heartbeat storage file
254 - mod_ldap: shared memory cache
255 - mod_socache_shmcb, mod_socache_dbm: shared memory or dbm for cache
258 *) suexec: Add --enable-suexec-capabilites support on Linux, to use
259 setuid/setgid capability bits rather than a setuid root binary.
262 *) suexec: Add support for logging to syslog as an alternative to logging
263 to a file; configure --without-suexec-logfile --with-suexec-syslog.
266 *) mod_ssl: Add support for TLS Next Protocol Negotiation. PR 52210.
267 [Matthew Steele <mdsteele google.com>]
269 *) cross-compile: allow to provide CC_FOR_BUILD so that gen_test_char will
270 be compiled by the build compiler instead of the host compiler.
271 Also set CC_FOR_BUILD to 'cc' when cross-compilation is detected.
272 PR 51257. [Guenter Knauf]
274 *) core: In maintainer mode, replace apr_palloc with a version that
275 initializes the allocated memory with non-zero values, except if
276 AP_DEBUG_NO_ALLOC_POISON is defined. [Stefan Fritsch]
278 *) mod_policy: Add a new testing module to help server administrators
279 enforce a configurable level of protocol compliance on their
280 servers and application servers behind theirs. [Graham Leggett]
282 *) mod_firehose: Add a new debugging module able to record traffic
283 passing through the server in such a way that connections and/or
284 requests be reconstructed and replayed. [Graham Leggett]
