2 Changes with Apache 2.5.0
4 *) core: Add ap_errorlog_provider to make ErrorLog logging modular. Move
5 syslog support from core to new mod_syslog. [Jan Kaluza]
7 *) mod_proxy_fcgi: Handle reading protocol data that is split between
8 packets. [Jeff Trawick]
10 *) mod_proxy_fcgi: Remove 64K limit on encoded length of all envvars.
11 An individual envvar with an encoded length of more than 16K will be
12 omitted. [Jeff Trawick]
14 *) core: draft-ietf-httpbis-p1-messaging-23 corrections regarding
15 TE/CL conflicts. [Yann Ylavic <ylavic.dev gmail com>, Jim Jagielski]
17 *) mod_proxy_fcgi: Use apr_socket_timeout_get instead of hard-coded
18 30 seconds timeout. [Jan Kaluza]
20 *) WinNT MPM: If ap_run_pre_connection() fails or sets c->aborted, don't
21 save the socket for reuse by the next worker as if it were an
22 APR_SO_DISCONNECTED socket. Restores 2.2 behavior. [Eric Covener]
24 *) mod_cache: Avoid a crash with strcmp() when the hostname is not provided.
27 *) mod_lua: Add rudimentary support for WebSocket interaction. This is
28 currently request-bound and only supports the WS protocol. [Daniel Gruno]
30 *) mod_lua: Add getcookie/setcookie for reading/writing HTTP cookies
33 *) WinNT MPM: Don't crash during child process initialization if the
34 Listen protocol is unrecognized. [Jeff Trawick]
36 *) mod_lua: Add a logging hook for modifying/skipping logs. [Daniel Gruno]
38 *) mod_status, mod_echo: Fix the display of client addresses.
39 They were truncated to 31 characters which is not enough for IPv6 addresses.
40 PR 54848 [Bernhard Schmidt <berni birkenwald de>]
42 *) mod_lua: If the first yield() of a LuaOutputFilter returns a string, it should
43 be prefixed to the response as documented. [Eric Covener]
45 *) mod_lua: Remove ETAG, Content-Length, and Content-MD5 when a LuaOutputFilter
46 is configured without mod_filter. [Eric Covener]
48 *) mod_lua: Register LuaOutputFilter scripts as changing the content and
49 content-length by default, when run my mod_filter. Previously,
50 growing or shrinking a response that started with Content-Length set
51 would require mod_filter and FilterProtocol change=yes. [Eric Covnener]
53 *) mod_lua: Return a 500 error if a LuaHook* script doesn't return a
54 numeric return code. [Eric Covener]
56 *) Add experimental cmake-based build system for Windows. [Jeff Trawick,
59 *) mod_authnz_fcgi: New module to enable FastCGI authorizer
60 applications to authenticate and/or authorize clients.
63 *) mod_auth_basic: Add AuthBasicUseDigestAlgorithm directive to
64 allow migration of passwords from digest to basic authentication.
67 *) core: Add util_fcgi.h and associated definitions and support
68 routines for FastCGI, based largely on mod_proxy_fcgi.
71 *) core: Add ap_log_data(), ap_log_rdata(), etc. for logging buffers.
74 *) mod_unique_id: Use output of the PRNG rather than IP address and
75 pid, avoiding sleep() call and possible DNS issues at startup,
76 plus improving randomness for IPv6-only hosts.
77 [Jan Kaluza <jkaluza redhat.com>]
79 *) mod_authnz_ldap: Support primitive LDAP servers that do not accept
80 filters, such as "SDBM-backed LDAP" on z/OS, by allowing a special
81 filter "none" to be specified in AuthLDAPURL. [Eric Covener]
83 *) mod_file_cache: mod_file_cache should be able to serve files that
84 haven't had a Content-Type set via e.g. mod_mime. [Eric Covener]
86 *) core: merge AllowEncodedSlashes from the base configuration into
87 virtual hosts. [Eric Covener]
89 *) AIX: Install DSO's with "cp" instead of "install" in instdso.sh
92 *) mod_ldap: Don't keep retrying if a new LDAP connection times out.
95 *) mod_deflate: permit compilation of mod_deflate against a zlib that has
96 been configured with -D Z_PREFIX, which redefines the token "deflate".
99 *) mod_socache_shmcb.c: Remove arbitrary restriction on shared memory size
100 previously limited to 64MB. [Jens Låås <jelaas gmail.com>]
102 *) mod_auth_digest: Use the secret when generating nonces in all cases and
103 not only when AuthName is used in .htaccess files (this change may cause
104 problems if used with round robin load balancers). Don't regenerate the
105 secret on graceful restarts. PR 54637 [Stefan Fritsch]
107 *) ab: Add a new -l parameter in order not to check the length of the responses.
108 This can be usefull with dynamic pages.
109 PR9945, PR27888, PR42040 [<ccikrs1 cranbrook edu>]
111 *) mod_logio: new format-specifier %C (combined) which is the sum of received
112 and sent byte counts.
113 PR54015 [Christophe Jaillet]
115 *) core: Remove apr_brigade_flatten(), buffering and duplicated code
116 from the HTTP_IN filter, parse chunks in a single pass with zero copy.
117 Reduce memory usage by 48 bytes per request. [Graham Leggett]
119 *) core: Stop the HTTP_IN filter from attempting to write error buckets
120 to the output filters, which is bogus in the proxy case. Create a
121 clean mapping from APR codes to HTTP status codes, and use it where
122 needed. [Graham Leggett]
124 *) mod_proxy: Ensure network errors detected by the proxy are returned as
125 504 Gateway Timout as opposed to 502 Bad Gateway, in order to be
126 compliant with RFC2616 14.9.4 Cache Revalidation and Reload Controls.
128 *) mod_dav: mod_dav overrides dav_fs response on PUT failure. PR 35981
129 [Basant Kumar Kukreja <basant.kukreja sun.com>, Alejandro Alvarez
130 <alejandro.alvarez.ayllon cern.ch>]
132 *) core, mod_ssl: Enable the ability for a module to reverse the sense of
133 a poll event from a read to a write or vice versa. This is a step on
134 the way to allow mod_ssl taking full advantage of the event MPM.
137 *) mod_ldap: LDAP connections used for authentication were not respecting
138 LDAPConnectionPoolTimeout. PR 54587
140 *) core: ap_rgetline_core now pulls from r->proto_input_filters.
142 *) mod_proxy_html: process parsed comments immediately.
143 Fixes bug where parsed comments may be lost. [Nick Kew]
145 *) mod_proxy_html: introduce doctype for HTML 5 [Nick Kew]
147 *) mod_proxy_html: fix typo-bug processing "strict" vs "transitional"
148 HTML/XHTML [Nick Kew]
150 *) core: Add option to add valgrind support. Use it to reduce false positive
151 warnings in mod_ssl. [Stefan Fritsch]
153 *) mod_authn_file, mod_authn_dbd, mod_authn_dbm, mod_authn_socache:
154 Cache the result of the most recent password hash verification for every
155 keep-alive connection. This saves some expensive calculations.
158 *) http: Remove support for Request-Range header sent by Navigator 2-3 and
159 MSIE 3. [Stefan Fritsch]
161 *) core, http: Extend HttpProtocol with an option to enforce stricter HTTP
162 conformance or to only log the found problems. [Stefan Fritsch]
164 *) core: Correctly parse an IPv6 literal host specification in an absolute
165 URL in the request line. [Stefan Fritsch]
167 *) mod_ssl: Add support for OpenSSL configuration commands [Stephen Henson]
171 *) core: Add LogLevelOverride directive that allows to override the
172 loglevel for clients from certain IPs. This also works for things
173 like the SSL handshake where <If> LogLevel ... </If> is evaluated
174 too late. [Stefan Fritsch]
176 *) core: Add new directive Warning to issue warnings from a configuration
177 file. Both Warning and Error now generate a timestamped log message.
180 *) ap_expr: Add SERVER_PROTOCOL_VERSION, ..._MAJOR, and ..._MINOR
181 variables. [Stefan Fritsch]
183 *) core: New directive RegisterHttpMethod for registering non-standard
184 HTTP methods. [Stefan Fritsch]
186 *) core: New directive HttpProtocol which allows to disable HTTP/0.9
187 support. [Stefan Fritsch]
189 *) mod_allowhandlers: New module to forbid specific handlers for specific
190 directories. [Stefan Fritsch]
192 *) mod_systemd: New module, for integration with systemd on Linux.
193 [Jan Kaluza <jkaluza redhat.com>]
195 *) WinNT MPM: Store pid and generation for each thread in scoreboard
196 to allow tracking of threads from exiting children via mod_status
197 or other such mechanisms. [Jeff Trawick]
199 *) mod_ssl: Catch missing or mismatched client cert/key pairs with
200 SSLProxyMachineCertificateFile/Path directives. PR 52212.
201 [Keith Burdis <keith burdis.org>, Joe Orton]
203 *) The following now respect DefaultRuntimeDir/DEFAULT_REL_RUNTIMEDIR:
204 - APIs: ap_log_pid(), ap_remove_pid, ap_read_pid()
205 - core: the scoreboard (ScoreBoardFile), pid file (PidFile), and
207 - mod_cache: thundering herd lock directory
208 - mod_lbmethod_heartbeat, mod_heartmonitor: heartbeat storage file
209 - mod_ldap: shared memory cache
210 - mod_socache_shmcb, mod_socache_dbm: shared memory or dbm for cache
213 *) suexec: Add --enable-suexec-capabilites support on Linux, to use
214 setuid/setgid capability bits rather than a setuid root binary.
217 *) suexec: Add support for logging to syslog as an alternative to logging
218 to a file; configure --without-suexec-logfile --with-suexec-syslog.
221 *) mod_ssl: Add support for TLS Next Protocol Negotiation. PR 52210.
222 [Matthew Steele <mdsteele google.com>]
224 *) cross-compile: allow to provide CC_FOR_BUILD so that gen_test_char will
225 be compiled by the build compiler instead of the host compiler.
226 Also set CC_FOR_BUILD to 'cc' when cross-compilation is detected.
227 PR 51257. [Guenter Knauf]
229 *) core: In maintainer mode, replace apr_palloc with a version that
230 initializes the allocated memory with non-zero values, except if
231 AP_DEBUG_NO_ALLOC_POISON is defined. [Stefan Fritsch]
233 *) mod_policy: Add a new testing module to help server administrators
234 enforce a configurable level of protocol compliance on their
235 servers and application servers behind theirs. [Graham Leggett]
237 *) mod_firehose: Add a new debugging module able to record traffic
238 passing through the server in such a way that connections and/or
239 requests be reconstructed and replayed. [Graham Leggett]
