2 Changes with Apache 2.5.0
4 *) WinNT MPM: If ap_run_pre_connection() fails or sets c->aborted, don't
5 save the socket for reuse by the next worker as if it were an
6 APR_SO_DISCONNECTED socket. Restores 2.2 behavior. [Eric Covener]
8 *) mod_auth_digest: Be more specific when the realm mismatches because the
9 realm has not been specified. [Graham Leggett]
11 *) mod_cache: Avoid a crash with strcmp() when the hostname is not provided.
14 *) mod_lua: Add rudimentary support for WebSocket interaction. This is
15 currently request-bound and only supports the WS protocol. [Daniel Gruno]
17 *) mod_lua: Add getcookie/setcookie for reading/writing HTTP cookies
20 *) mod_headers: Add 'Header note header-name note-name' for copying a response
21 headers value into a note. [Eric Covener]
23 *) WinNT MPM: Don't crash during child process initialization if the
24 Listen protocol is unrecognized. [Jeff Trawick]
26 *) mod_lua: Add a logging hook for modifying/skipping logs. [Daniel Gruno]
28 *) mod_status, mod_echo: Fix the display of client addresses.
29 They were truncated to 31 characters which is not enough for IPv6 addresses.
30 PR 54848 [Bernhard Schmidt <berni birkenwald de>]
32 *) mod_lua: If the first yield() of a LuaOutputFilter returns a string, it should
33 be prefixed to the response as documented. [Eric Covener]
35 *) mod_lua: Remove ETAG, Content-Length, and Content-MD5 when a LuaOutputFilter
36 is configured without mod_filter. [Eric Covener]
38 *) mod_lua: Register LuaOutputFilter scripts as changing the content and
39 content-length by default, when run my mod_filter. Previously,
40 growing or shrinking a response that started with Content-Length set
41 would require mod_filter and FilterProtocol change=yes. [Eric Covnener]
43 *) mod_filter: Add "change=no" as a proto-flag to FilterProtocol
44 to remove a providers initial flags set at registration time.
47 *) mod_lua: Return a 500 error if a LuaHook* script doesn't return a
48 numeric return code. [Eric Covener]
50 *) Add experimental cmake-based build system for Windows. [Jeff Trawick,
53 *) mod_ldap: Change "LDAPReferrals off" to actually set the underlying LDAP
54 SDK option to OFF, and introduce "LDAPReferrals default" to take the SDK
55 default, sans rebind authentication callback.
56 [Jan Kaluza <jkaluza AT redhat.com>]
58 *) mod_authz_groupfile, mod_authz_user: Reduce severity of AH01671 and AH01663
59 from ERROR to DEBUG, since these modules do not know what mod_authz_core
60 is doing with their AUTHZ_DENIED return value. [Eric Covener]
62 *) mod_authnz_fcgi: New module to enable FastCGI authorizer
63 applications to authenticate and/or authorize clients.
66 *) mod_auth_basic: Add AuthBasicUseDigestAlgorithm directive to
67 allow migration of passwords from digest to basic authentication.
70 *) core: Add util_fcgi.h and associated definitions and support
71 routines for FastCGI, based largely on mod_proxy_fcgi.
74 *) core: Add ap_log_data(), ap_log_rdata(), etc. for logging buffers.
77 *) mod_unique_id: Use output of the PRNG rather than IP address and
78 pid, avoiding sleep() call and possible DNS issues at startup,
79 plus improving randomness for IPv6-only hosts.
80 [Jan Kaluza <jkaluza redhat.com>]
82 *) core: Log a message at TRACE1 when the client aborts a connection.
85 *) mod_authnz_ldap: Support primitive LDAP servers that do not accept
86 filters, such as "SDBM-backed LDAP" on z/OS, by allowing a special
87 filter "none" to be specified in AuthLDAPURL. [Eric Covener]
89 *) mod_file_cache: mod_file_cache should be able to serve files that
90 haven't had a Content-Type set via e.g. mod_mime. [Eric Covener]
92 *) core: merge AllowEncodedSlashes from the base configuration into
93 virtual hosts. [Eric Covener]
95 *) mod_headers: Add 'setifempty' command to Header and RequestHeader.
98 *) AIX: Install DSO's with "cp" instead of "install" in instdso.sh
101 *) mod_ldap: Don't keep retrying if a new LDAP connection times out.
104 *) mod_deflate: permit compilation of mod_deflate against a zlib that has
105 been configured with -D Z_PREFIX, which redefines the token "deflate".
108 *) mod_socache_shmcb.c: Remove arbitrary restriction on shared memory size
109 previously limited to 64MB. [Jens Låås <jelaas gmail.com>]
111 *) mod_auth_digest: Use the secret when generating nonces in all cases and
112 not only when AuthName is used in .htaccess files (this change may cause
113 problems if used with round robin load balancers). Don't regenerate the
114 secret on graceful restarts. PR 54637 [Stefan Fritsch]
116 *) ab: Add a new -l parameter in order not to check the length of the responses.
117 This can be usefull with dynamic pages.
118 PR9945, PR27888, PR42040 [<ccikrs1 cranbrook edu>]
120 *) mod_logio: new format-specifier %C (combined) which is the sum of received
121 and sent byte counts.
122 PR54015 [Christophe Jaillet]
124 *) core: Remove apr_brigade_flatten(), buffering and duplicated code
125 from the HTTP_IN filter, parse chunks in a single pass with zero copy.
126 Reduce memory usage by 48 bytes per request. [Graham Leggett]
128 *) core: Stop the HTTP_IN filter from attempting to write error buckets
129 to the output filters, which is bogus in the proxy case. Create a
130 clean mapping from APR codes to HTTP status codes, and use it where
131 needed. [Graham Leggett]
133 *) mod_proxy: Ensure network errors detected by the proxy are returned as
134 504 Gateway Timout as opposed to 502 Bad Gateway, in order to be
135 compliant with RFC2616 14.9.4 Cache Revalidation and Reload Controls.
137 *) mod_dav: mod_dav overrides dav_fs response on PUT failure. PR 35981
138 [Basant Kumar Kukreja <basant.kukreja sun.com>, Alejandro Alvarez
139 <alejandro.alvarez.ayllon cern.ch>]
141 *) core, mod_ssl: Enable the ability for a module to reverse the sense of
142 a poll event from a read to a write or vice versa. This is a step on
143 the way to allow mod_ssl taking full advantage of the event MPM.
146 *) mod_ldap: LDAP connections used for authentication were not respecting
147 LDAPConnectionPoolTimeout. PR 54587
149 *) core: ap_rgetline_core now pulls from r->proto_input_filters.
151 *) mod_proxy_html: process parsed comments immediately.
152 Fixes bug where parsed comments may be lost. [Nick Kew]
154 *) mod_proxy_html: introduce doctype for HTML 5 [Nick Kew]
156 *) mod_proxy_html: fix typo-bug processing "strict" vs "transitional"
157 HTML/XHTML [Nick Kew]
159 *) core: Add option to add valgrind support. Use it to reduce false positive
160 warnings in mod_ssl. [Stefan Fritsch]
162 *) mod_authn_file, mod_authn_dbd, mod_authn_dbm, mod_authn_socache:
163 Cache the result of the most recent password hash verification for every
164 keep-alive connection. This saves some expensive calculations.
167 *) http: Remove support for Request-Range header sent by Navigator 2-3 and
168 MSIE 3. [Stefan Fritsch]
170 *) core, http: Extend HttpProtocol with an option to enforce stricter HTTP
171 conformance or to only log the found problems. [Stefan Fritsch]
173 *) core: Correctly parse an IPv6 literal host specification in an absolute
174 URL in the request line. [Stefan Fritsch]
176 *) mod_ssl: Add support for OpenSSL configuration commands [Stephen Henson]
180 *) core: Add LogLevelOverride directive that allows to override the
181 loglevel for clients from certain IPs. This also works for things
182 like the SSL handshake where <If> LogLevel ... </If> is evaluated
183 too late. [Stefan Fritsch]
185 *) core: Add new directive Warning to issue warnings from a configuration
186 file. Both Warning and Error now generate a timestamped log message.
189 *) ap_expr: Add SERVER_PROTOCOL_VERSION, ..._MAJOR, and ..._MINOR
190 variables. [Stefan Fritsch]
192 *) core: New directive RegisterHttpMethod for registering non-standard
193 HTTP methods. [Stefan Fritsch]
195 *) core: New directive HttpProtocol which allows to disable HTTP/0.9
196 support. [Stefan Fritsch]
198 *) mod_allowhandlers: New module to forbid specific handlers for specific
199 directories. [Stefan Fritsch]
201 *) mod_systemd: New module, for integration with systemd on Linux.
202 [Jan Kaluza <jkaluza redhat.com>]
204 *) WinNT MPM: Store pid and generation for each thread in scoreboard
205 to allow tracking of threads from exiting children via mod_status
206 or other such mechanisms. [Jeff Trawick]
208 *) mod_ssl: Catch missing or mismatched client cert/key pairs with
209 SSLProxyMachineCertificateFile/Path directives. PR 52212.
210 [Keith Burdis <keith burdis.org>, Joe Orton]
212 *) The following now respect DefaultRuntimeDir/DEFAULT_REL_RUNTIMEDIR:
213 - APIs: ap_log_pid(), ap_remove_pid, ap_read_pid()
214 - core: the scoreboard (ScoreBoardFile), pid file (PidFile), and
216 - mod_cache: thundering herd lock directory
217 - mod_lbmethod_heartbeat, mod_heartmonitor: heartbeat storage file
218 - mod_ldap: shared memory cache
219 - mod_socache_shmcb, mod_socache_dbm: shared memory or dbm for cache
222 *) suexec: Add --enable-suexec-capabilites support on Linux, to use
223 setuid/setgid capability bits rather than a setuid root binary.
226 *) suexec: Add support for logging to syslog as an alternative to logging
227 to a file; configure --without-suexec-logfile --with-suexec-syslog.
230 *) mod_ssl: Add support for TLS Next Protocol Negotiation. PR 52210.
231 [Matthew Steele <mdsteele google.com>]
233 *) cross-compile: allow to provide CC_FOR_BUILD so that gen_test_char will
234 be compiled by the build compiler instead of the host compiler.
235 Also set CC_FOR_BUILD to 'cc' when cross-compilation is detected.
236 PR 51257. [Guenter Knauf]
238 *) core: In maintainer mode, replace apr_palloc with a version that
239 initializes the allocated memory with non-zero values, except if
240 AP_DEBUG_NO_ALLOC_POISON is defined. [Stefan Fritsch]
242 *) mod_policy: Add a new testing module to help server administrators
243 enforce a configurable level of protocol compliance on their
244 servers and application servers behind theirs. [Graham Leggett]
246 *) mod_firehose: Add a new debugging module able to record traffic
247 passing through the server in such a way that connections and/or
248 requests be reconstructed and replayed. [Graham Leggett]
