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