2 Changes with Apache 2.5.0
4 *) mod_rewrite: Rename the handler that does per-directory internal
5 redirects to "rewrite-redirect-handler" from "redirect-handler" so
6 it is less ambiguous and less likely to be reused. [Eric Covener]
8 *) mod_dir: Add DirectoryCheckHandler to allow a 2.2-like behavior, skipping
9 execution when a handler is already set. PR53929. [Eric Covener]
11 *) mod_rewrite: Protect against looping with the [N] flag by enforcing a
12 default limit of 10000 iterations, and allowing each rule to change its
15 *) mod_ssl: Fix config merging of SSLOCSPEnable and SSLOCSPOverrideResponder.
18 *) Add HttpContentLengthHeadZero and HttpExpectStrict directives.
19 [Yehuda Sadeh <yehuda inktank com>, Justin Erenkrantz]
21 *) core: Support named groups and backreferences within the LocationMatch,
22 DirectoryMatch, FilesMatch and ProxyMatch directives. [Graham Leggett]
24 *) mod_ssl: Remove the hardcoded algorithm-type dependency for the
25 SSLCertificateFile and SSLCertificateKeyFile directives, to enable
26 future algorithm agility, and deprecate the SSLCertificateChainFile
27 directive (obsoleted by SSLCertificateFile). [Kaspar Brand]
29 *) FreeBSD: Disable IPv4-mapped listening sockets by default for versions
30 5+ instead of just for FreeBSD 5. PR 53824. [Jeff Trawick]
32 *) mod_auth_form: Add a debug message when the fields on a form are not
33 recognised. [Graham Leggett]
35 *) mod_ssl: Add -t -DDUMP_CA_CERTS option which dumps the filenames of all
36 configured SSL CA certificates to stdout the same way as DUMP_CERTS does.
39 *) mod_headers: Allow the "value" parameter of Header and RequestHeader to
40 contain an ap_expr expression if prefixed with "expr=". [Eric Covener]
42 *) Add suspend_connection and resume_connection hooks to notify modules
43 when the thread/connection relationship changes. (Currently implemented
44 only for the Event MPM; should be implemented for all async MPMs.)
47 *) mod_ssl: Don't flush when an EOS is received. Prepares mod_ssl
48 to support write completion. [Graham Leggett]
50 *) prefork: Fix long delays when doing a graceful restart.
51 PR 54852 [Jim Jagielski, Arkadiusz Miskiewicz <arekm maven pl>]
53 *) core: Add parse_errorlog_arg callback to ap_errorlog_provider
54 to allow providers to check the ErrorLog argument. [Jan Kaluza]
56 *) core: Detect incomplete body in HTTP input filter and return
57 APR_INCOMPLETE. PR 55475 [Yann Ylavic <ylavic dev gmail com>]
59 *) mod_cgid: Use the servers Timeout for each read from a CGI script,
60 allow override with new CGIDRequestTimeout directive. PR43494

69 *) mod_proxy: Added support for unix domain sockets as the
70 backend server endpoint [Jim Jagielski, Blaise Tarr
71 <blaise tarr gmail com>]
73 *) mod_auth_form: Make sure the optional functions are loaded even when
74 the AuthFormProvider isn't specified. [Graham Leggett]
76 *) mod_lua: Let the Inter-VM get/set functions work with a global
77 shared memory pool instead of a per-process pool. [Daniel Gruno]
79 *) ldap: Support ldaps when using the Microsoft LDAP SDK.
80 PR 54626. [Jean-Frederic Clere]
82 *) mod_proxy: Add ap_connection_reusable() for checking if a connection
83 is reusable as of this point in processing. [Jeff Trawick]
85 *) mod_authnz_ldap: Change default value of AuthLDAPMaxSubGroupDepth to 0
86 to avoid performance problems when subgroups aren't in use. [Eric Covener]
88 *) mod_syslog: New module implementing syslog ap_error_log provider.
89 Previously, this code was part of core, now it's in separate module.
92 *) core: Add ap_errorlog_provider to make ErrorLog logging modular. Move
93 syslog support from core to new mod_syslog. [Jan Kaluza]
95 *) core: draft-ietf-httpbis-p1-messaging-23 corrections regarding
96 TE/CL conflicts. [Yann Ylavic <ylavic.dev gmail com>, Jim Jagielski]
98 *) WinNT MPM: If ap_run_pre_connection() fails or sets c->aborted, don't
99 save the socket for reuse by the next worker as if it were an
100 APR_SO_DISCONNECTED socket. Restores 2.2 behavior. [Eric Covener]
102 *) mod_lua: Add a logging hook for modifying/skipping logs. [Daniel Gruno]
104 *) mod_status, mod_echo: Fix the display of client addresses.
105 They were truncated to 31 characters which is not enough for IPv6 addresses.
106 PR 54848 [Bernhard Schmidt <berni birkenwald de>]
108 *) mod_authnz_fcgi: New module to enable FastCGI authorizer
109 applications to authenticate and/or authorize clients.
112 *) core: Add ap_log_data(), ap_log_rdata(), etc. for logging buffers.
115 *) mod_unique_id: Use output of the PRNG rather than IP address and
116 pid, avoiding sleep() call and possible DNS issues at startup,
117 plus improving randomness for IPv6-only hosts.
118 [Jan Kaluza <jkaluza redhat.com>]
120 *) mod_authnz_ldap: Support primitive LDAP servers that do not accept
121 filters, such as "SDBM-backed LDAP" on z/OS, by allowing a special
122 filter "none" to be specified in AuthLDAPURL. [Eric Covener]
124 *) mod_file_cache: mod_file_cache should be able to serve files that
125 haven't had a Content-Type set via e.g. mod_mime. [Eric Covener]
127 *) core: merge AllowEncodedSlashes from the base configuration into
128 virtual hosts. [Eric Covener]
130 *) AIX: Install DSO's with "cp" instead of "install" in instdso.sh
133 *) mod_ldap: Don't keep retrying if a new LDAP connection times out.
136 *) mod_deflate: permit compilation of mod_deflate against a zlib that has
137 been configured with -D Z_PREFIX, which redefines the token "deflate".
140 *) mod_socache_shmcb.c: Remove arbitrary restriction on shared memory size
141 previously limited to 64MB. [Jens Låås <jelaas gmail.com>]
143 *) mod_auth_digest: Use the secret when generating nonces in all cases and
144 not only when AuthName is used in .htaccess files (this change may cause
145 problems if used with round robin load balancers). Don't regenerate the
146 secret on graceful restarts. PR 54637 [Stefan Fritsch]
148 *) core: Remove apr_brigade_flatten(), buffering and duplicated code
149 from the HTTP_IN filter, parse chunks in a single pass with zero copy.
150 Reduce memory usage by 48 bytes per request. [Graham Leggett]
152 *) core: Stop the HTTP_IN filter from attempting to write error buckets
153 to the output filters, which is bogus in the proxy case. Create a
154 clean mapping from APR codes to HTTP status codes, and use it where
155 needed. [Graham Leggett]
157 *) mod_proxy: Ensure network errors detected by the proxy are returned as
158 504 Gateway Timout as opposed to 502 Bad Gateway, in order to be
159 compliant with RFC2616 14.9.4 Cache Revalidation and Reload Controls.
161 *) mod_dav: mod_dav overrides dav_fs response on PUT failure. PR 35981
162 [Basant Kumar Kukreja <basant.kukreja sun.com>, Alejandro Alvarez
163 <alejandro.alvarez.ayllon cern.ch>]
165 *) core, mod_ssl: Enable the ability for a module to reverse the sense of
166 a poll event from a read to a write or vice versa. This is a step on
167 the way to allow mod_ssl taking full advantage of the event MPM.
170 *) mod_ldap: LDAP connections used for authentication were not respecting
171 LDAPConnectionPoolTimeout. PR 54587
173 *) core: ap_rgetline_core now pulls from r->proto_input_filters.
175 *) mod_proxy_html: process parsed comments immediately.
176 Fixes bug where parsed comments may be lost. [Nick Kew]
178 *) mod_proxy_html: introduce doctype for HTML 5 [Nick Kew]
180 *) mod_proxy_html: fix typo-bug processing "strict" vs "transitional"
181 HTML/XHTML [Nick Kew]
183 *) core: Add option to add valgrind support. Use it to reduce false positive
184 warnings in mod_ssl. [Stefan Fritsch]
186 *) mod_authn_file, mod_authn_dbd, mod_authn_dbm, mod_authn_socache:
187 Cache the result of the most recent password hash verification for every
188 keep-alive connection. This saves some expensive calculations.
191 *) http: Remove support for Request-Range header sent by Navigator 2-3 and
192 MSIE 3. [Stefan Fritsch]
194 *) core, http: Extend HttpProtocol with an option to enforce stricter HTTP
195 conformance or to only log the found problems. [Stefan Fritsch]
197 *) core: Correctly parse an IPv6 literal host specification in an absolute
198 URL in the request line. [Stefan Fritsch]
202 *) core: Add LogLevelOverride directive that allows to override the
203 loglevel for clients from certain IPs. This also works for things
204 like the SSL handshake where <If> LogLevel ... </If> is evaluated
205 too late. [Stefan Fritsch]
207 *) core: Add new directive Warning to issue warnings from a configuration
208 file. Both Warning and Error now generate a timestamped log message.
211 *) ap_expr: Add SERVER_PROTOCOL_VERSION, ..._MAJOR, and ..._MINOR
212 variables. [Stefan Fritsch]
214 *) core: New directive RegisterHttpMethod for registering non-standard
215 HTTP methods. [Stefan Fritsch]
217 *) core: New directive HttpProtocol which allows to disable HTTP/0.9
218 support. [Stefan Fritsch]
220 *) mod_allowhandlers: New module to forbid specific handlers for specific
221 directories. [Stefan Fritsch]
223 *) mod_systemd: New module, for integration with systemd on Linux.
224 [Jan Kaluza <jkaluza redhat.com>]
226 *) WinNT MPM: Store pid and generation for each thread in scoreboard
227 to allow tracking of threads from exiting children via mod_status
228 or other such mechanisms. [Jeff Trawick]
230 *) The following now respect DefaultRuntimeDir/DEFAULT_REL_RUNTIMEDIR:
231 - APIs: ap_log_pid(), ap_remove_pid, ap_read_pid()
232 - core: the scoreboard (ScoreBoardFile), pid file (PidFile), and
234 - mod_cache: thundering herd lock directory
235 - mod_lbmethod_heartbeat, mod_heartmonitor: heartbeat storage file
236 - mod_ldap: shared memory cache
237 - mod_socache_shmcb, mod_socache_dbm: shared memory or dbm for cache
240 *) suexec: Add --enable-suexec-capabilites support on Linux, to use
241 setuid/setgid capability bits rather than a setuid root binary.
244 *) suexec: Add support for logging to syslog as an alternative to logging
245 to a file; configure --without-suexec-logfile --with-suexec-syslog.
248 *) mod_ssl: Add support for TLS Next Protocol Negotiation. PR 52210.
249 [Matthew Steele <mdsteele google.com>]
251 *) cross-compile: allow to provide CC_FOR_BUILD so that gen_test_char will
252 be compiled by the build compiler instead of the host compiler.
253 Also set CC_FOR_BUILD to 'cc' when cross-compilation is detected.
254 PR 51257. [Guenter Knauf]
256 *) core: In maintainer mode, replace apr_palloc with a version that
257 initializes the allocated memory with non-zero values, except if
258 AP_DEBUG_NO_ALLOC_POISON is defined. [Stefan Fritsch]
260 *) mod_policy: Add a new testing module to help server administrators
261 enforce a configurable level of protocol compliance on their
262 servers and application servers behind theirs. [Graham Leggett]
264 *) mod_firehose: Add a new debugging module able to record traffic
265 passing through the server in such a way that connections and/or
266 requests be reconstructed and replayed. [Graham Leggett]
