2 Changes with Apache 2.5.0
4 *) mod_reqtimeout: Resolve unexpected timeouts on keepalive requests
5 under the Event MPM. PR56216. [Frank Meier <frank meier ergon ch>]
7 *) mod_lua: Add r:wspeek for checking if there is any data waiting on the line
10 *) mod_proxy: Do not try to parse the regular expressions passed by
11 ProxyPassMatch as URL as they do not follow their syntax.
12 PR 56074. [Ruediger Pluem]
14 *) mod_dir: Default to 2.2-like behavior and skip execution when method is
15 neither GET nor POST, such as for DAV requests. PR 54914. [Chris Darroch]
17 *) mod_rewrite: Rename the handler that does per-directory internal
18 redirects to "rewrite-redirect-handler" from "redirect-handler" so
19 it is less ambiguous and less likely to be reused. [Eric Covener]
21 *) mod_rewrite: Protect against looping with the [N] flag by enforcing a
22 default limit of 10000 iterations, and allowing each rule to change its
25 *) mod_ssl: Fix config merging of SSLOCSPEnable and SSLOCSPOverrideResponder.
28 *) Add HttpContentLengthHeadZero and HttpExpectStrict directives.
29 [Yehuda Sadeh <yehuda inktank com>, Justin Erenkrantz]

32 5+ instead of just for FreeBSD 5. PR 53824. [Jeff Trawick]
34 *) mod_auth_form: Add a debug message when the fields on a form are not
35 recognised. [Graham Leggett]
37 *) mod_ssl: Add -t -DDUMP_CA_CERTS option which dumps the filenames of all
38 configured SSL CA certificates to stdout the same way as DUMP_CERTS does.
41 *) mod_headers: Allow the "value" parameter of Header and RequestHeader to
42 contain an ap_expr expression if prefixed with "expr=". [Eric Covener]
44 *) Add suspend_connection and resume_connection hooks to notify modules
45 when the thread/connection relationship changes. (Currently implemented
46 only for the Event MPM; should be implemented for all async MPMs.)
49 *) mod_ssl: Don't flush when an EOS is received. Prepares mod_ssl
50 to support write completion. [Graham Leggett]
52 *) core: Add parse_errorlog_arg callback to ap_errorlog_provider
53 to allow providers to check the ErrorLog argument. [Jan Kaluza]

56 APR_INCOMPLETE. PR 55475 [Yann Ylavic <ylavic dev gmail com>]
58 *) mod_cgid: Use the servers Timeout for each read from a CGI script,
59 allow override with new CGIDRequestTimeout directive. PR43494

63 PR 54946. [Rainer Jung]
65 *) core: ensure any abnormal exit is reported to stderr if it's a tty.
68 *) mod_auth_form: Make sure the optional functions are loaded even when

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