2 Changes with Apache 2.5.0
3 *) ldap: Allow to support ldaps on the microsoft ldap sdk
4 PR 54626. [Jean-Frederic Clere]
6 *) worker MPM: Don't forcibly kill worker threads if the child process is
7 exiting gracefully. [Oracle Corporation]
9 *) mod_proxy: Add ap_connection_reusable() for checking if a connection
10 is reusable as of this point in processing. [Jeff Trawick]
12 *) mod_ssl: drop support for export-grade ciphers with ephemeral RSA
13 keys, and unconditionally disable aNULL, eNULL and EXP ciphers
14 (not overridable via SSLCipherSuite). [Kaspar Brand]
16 *) Suppress formatting of startup messages written to the console when
17 ErrorLogFormat is used. [Jeff Trawick]
19 *) mod_authnz_ldap: Change default value of AuthLDAPMaxSubGroupDepth to 0
20 to avoid performance problems when subgroups aren't in use. [Eric Covener]
22 *) mod_syslog: New module implementing syslog ap_error_log provider.
23 Previously, this code was part of core, now it's in separate module.
26 *) core: Add ap_errorlog_provider to make ErrorLog logging modular. Move
27 syslog support from core to new mod_syslog. [Jan Kaluza]
29 *) mod_proxy_fcgi: Handle reading protocol data that is split between
30 packets. [Jeff Trawick]
32 *) mod_proxy_fcgi: Remove 64K limit on encoded length of all envvars.
33 An individual envvar with an encoded length of more than 16K will be
34 omitted. [Jeff Trawick]
36 *) core: draft-ietf-httpbis-p1-messaging-23 corrections regarding
37 TE/CL conflicts. [Yann Ylavic <ylavic.dev gmail com>, Jim Jagielski]
39 *) mod_proxy_fcgi: Use apr_socket_timeout_get instead of hard-coded
40 30 seconds timeout. [Jan Kaluza]
42 *) WinNT MPM: If ap_run_pre_connection() fails or sets c->aborted, don't
43 save the socket for reuse by the next worker as if it were an
44 APR_SO_DISCONNECTED socket. Restores 2.2 behavior. [Eric Covener]
46 *) mod_cache: Avoid a crash with strcmp() when the hostname is not provided.
49 *) mod_lua: Add rudimentary support for WebSocket interaction. This is
50 currently request-bound and only supports the WS protocol. [Daniel Gruno]
52 *) mod_lua: Add getcookie/setcookie for reading/writing HTTP cookies
55 *) WinNT MPM: Don't crash during child process initialization if the
56 Listen protocol is unrecognized. [Jeff Trawick]
58 *) mod_lua: Add a logging hook for modifying/skipping logs. [Daniel Gruno]
60 *) mod_status, mod_echo: Fix the display of client addresses.
61 They were truncated to 31 characters which is not enough for IPv6 addresses.
62 PR 54848 [Bernhard Schmidt <berni birkenwald de>]
64 *) mod_lua: If the first yield() of a LuaOutputFilter returns a string, it should
65 be prefixed to the response as documented. [Eric Covener]
67 *) mod_lua: Remove ETAG, Content-Length, and Content-MD5 when a LuaOutputFilter
68 is configured without mod_filter. [Eric Covener]
70 *) mod_lua: Register LuaOutputFilter scripts as changing the content and
71 content-length by default, when run my mod_filter. Previously,
72 growing or shrinking a response that started with Content-Length set
73 would require mod_filter and FilterProtocol change=yes. [Eric Covnener]
75 *) mod_lua: Return a 500 error if a LuaHook* script doesn't return a
76 numeric return code. [Eric Covener]
78 *) Add experimental cmake-based build system for Windows. [Jeff Trawick,
81 *) mod_authnz_fcgi: New module to enable FastCGI authorizer
82 applications to authenticate and/or authorize clients.
85 *) mod_auth_basic: Add AuthBasicUseDigestAlgorithm directive to
86 allow migration of passwords from digest to basic authentication.
89 *) core: Add util_fcgi.h and associated definitions and support
90 routines for FastCGI, based largely on mod_proxy_fcgi.
93 *) core: Add ap_log_data(), ap_log_rdata(), etc. for logging buffers.
96 *) mod_unique_id: Use output of the PRNG rather than IP address and
97 pid, avoiding sleep() call and possible DNS issues at startup,
98 plus improving randomness for IPv6-only hosts.
99 [Jan Kaluza <jkaluza redhat.com>]
101 *) mod_authnz_ldap: Support primitive LDAP servers that do not accept
102 filters, such as "SDBM-backed LDAP" on z/OS, by allowing a special
103 filter "none" to be specified in AuthLDAPURL. [Eric Covener]
105 *) mod_file_cache: mod_file_cache should be able to serve files that
106 haven't had a Content-Type set via e.g. mod_mime. [Eric Covener]
108 *) core: merge AllowEncodedSlashes from the base configuration into
109 virtual hosts. [Eric Covener]
111 *) AIX: Install DSO's with "cp" instead of "install" in instdso.sh
114 *) mod_ldap: Don't keep retrying if a new LDAP connection times out.
117 *) mod_deflate: permit compilation of mod_deflate against a zlib that has
118 been configured with -D Z_PREFIX, which redefines the token "deflate".
121 *) mod_socache_shmcb.c: Remove arbitrary restriction on shared memory size
122 previously limited to 64MB. [Jens Låås <jelaas gmail.com>]
124 *) mod_auth_digest: Use the secret when generating nonces in all cases and
125 not only when AuthName is used in .htaccess files (this change may cause
126 problems if used with round robin load balancers). Don't regenerate the
127 secret on graceful restarts. PR 54637 [Stefan Fritsch]
129 *) ab: Add a new -l parameter in order not to check the length of the responses.
130 This can be usefull with dynamic pages.
131 PR9945, PR27888, PR42040 [<ccikrs1 cranbrook edu>]
133 *) mod_logio: new format-specifier %C (combined) which is the sum of received
134 and sent byte counts.
135 PR54015 [Christophe Jaillet]
137 *) core: Remove apr_brigade_flatten(), buffering and duplicated code
138 from the HTTP_IN filter, parse chunks in a single pass with zero copy.
139 Reduce memory usage by 48 bytes per request. [Graham Leggett]
141 *) core: Stop the HTTP_IN filter from attempting to write error buckets
142 to the output filters, which is bogus in the proxy case. Create a
143 clean mapping from APR codes to HTTP status codes, and use it where
144 needed. [Graham Leggett]
146 *) mod_proxy: Ensure network errors detected by the proxy are returned as
147 504 Gateway Timout as opposed to 502 Bad Gateway, in order to be
148 compliant with RFC2616 14.9.4 Cache Revalidation and Reload Controls.
150 *) mod_dav: mod_dav overrides dav_fs response on PUT failure. PR 35981
151 [Basant Kumar Kukreja <basant.kukreja sun.com>, Alejandro Alvarez
152 <alejandro.alvarez.ayllon cern.ch>]
154 *) core, mod_ssl: Enable the ability for a module to reverse the sense of
155 a poll event from a read to a write or vice versa. This is a step on
156 the way to allow mod_ssl taking full advantage of the event MPM.
159 *) mod_ldap: LDAP connections used for authentication were not respecting
160 LDAPConnectionPoolTimeout. PR 54587
162 *) core: ap_rgetline_core now pulls from r->proto_input_filters.
164 *) mod_proxy_html: process parsed comments immediately.
165 Fixes bug where parsed comments may be lost. [Nick Kew]
167 *) mod_proxy_html: introduce doctype for HTML 5 [Nick Kew]
169 *) mod_proxy_html: fix typo-bug processing "strict" vs "transitional"
170 HTML/XHTML [Nick Kew]
172 *) core: Add option to add valgrind support. Use it to reduce false positive
173 warnings in mod_ssl. [Stefan Fritsch]
175 *) mod_authn_file, mod_authn_dbd, mod_authn_dbm, mod_authn_socache:
176 Cache the result of the most recent password hash verification for every
177 keep-alive connection. This saves some expensive calculations.
180 *) http: Remove support for Request-Range header sent by Navigator 2-3 and
181 MSIE 3. [Stefan Fritsch]
183 *) core, http: Extend HttpProtocol with an option to enforce stricter HTTP
184 conformance or to only log the found problems. [Stefan Fritsch]
186 *) core: Correctly parse an IPv6 literal host specification in an absolute
187 URL in the request line. [Stefan Fritsch]
189 *) mod_ssl: Add support for OpenSSL configuration commands [Stephen Henson]
193 *) core: Add LogLevelOverride directive that allows to override the
194 loglevel for clients from certain IPs. This also works for things
195 like the SSL handshake where <If> LogLevel ... </If> is evaluated
196 too late. [Stefan Fritsch]
198 *) core: Add new directive Warning to issue warnings from a configuration
199 file. Both Warning and Error now generate a timestamped log message.
202 *) ap_expr: Add SERVER_PROTOCOL_VERSION, ..._MAJOR, and ..._MINOR
203 variables. [Stefan Fritsch]
205 *) core: New directive RegisterHttpMethod for registering non-standard
206 HTTP methods. [Stefan Fritsch]
208 *) core: New directive HttpProtocol which allows to disable HTTP/0.9
209 support. [Stefan Fritsch]
211 *) mod_allowhandlers: New module to forbid specific handlers for specific
212 directories. [Stefan Fritsch]
214 *) mod_systemd: New module, for integration with systemd on Linux.
215 [Jan Kaluza <jkaluza redhat.com>]
217 *) WinNT MPM: Store pid and generation for each thread in scoreboard
218 to allow tracking of threads from exiting children via mod_status
219 or other such mechanisms. [Jeff Trawick]
221 *) The following now respect DefaultRuntimeDir/DEFAULT_REL_RUNTIMEDIR:
222 - APIs: ap_log_pid(), ap_remove_pid, ap_read_pid()
223 - core: the scoreboard (ScoreBoardFile), pid file (PidFile), and
225 - mod_cache: thundering herd lock directory
226 - mod_lbmethod_heartbeat, mod_heartmonitor: heartbeat storage file
227 - mod_ldap: shared memory cache
228 - mod_socache_shmcb, mod_socache_dbm: shared memory or dbm for cache
231 *) suexec: Add --enable-suexec-capabilites support on Linux, to use
232 setuid/setgid capability bits rather than a setuid root binary.
235 *) suexec: Add support for logging to syslog as an alternative to logging
236 to a file; configure --without-suexec-logfile --with-suexec-syslog.
239 *) mod_ssl: Add support for TLS Next Protocol Negotiation. PR 52210.
240 [Matthew Steele <mdsteele google.com>]
242 *) cross-compile: allow to provide CC_FOR_BUILD so that gen_test_char will
243 be compiled by the build compiler instead of the host compiler.
244 Also set CC_FOR_BUILD to 'cc' when cross-compilation is detected.
245 PR 51257. [Guenter Knauf]
247 *) core: In maintainer mode, replace apr_palloc with a version that
248 initializes the allocated memory with non-zero values, except if
249 AP_DEBUG_NO_ALLOC_POISON is defined. [Stefan Fritsch]
251 *) mod_policy: Add a new testing module to help server administrators
252 enforce a configurable level of protocol compliance on their
253 servers and application servers behind theirs. [Graham Leggett]
255 *) mod_firehose: Add a new debugging module able to record traffic
256 passing through the server in such a way that connections and/or
257 requests be reconstructed and replayed. [Graham Leggett]
