2 Changes with Apache 2.5.0
4 *) mod_lua: If the first yield() of a LuaOutputFilter returns a string, it should
5 be prefixed to the response as documented. [Eric Covener]
7 *) mod_lua: Remove ETAG, Content-Length, and Content-MD5 when a LuaOutputFilter
8 is configured without mod_filter. [Eric Covener]
10 *) mod_lua: Register LuaOutputFilter scripts as changing the content and
11 content-length by default, when run my mod_filter. Previously,
12 growing or shrinking a response that started with Content-Length set
13 would require mod_filter and FilterProtocol change=yes. [Eric Covnener]
15 *) mod_filter: Add "change=no" as a proto-flag to FilterProtocol
16 to remove a providers initial flags set at registration time.
19 *) mod_lua: Return a 500 error if a LuaHook* script doesn't return a
20 numeric return code. [Eric Covener]
22 *) Add experimental cmake-based build system for Windows. [Jeff Trawick,
25 *) mod_ldap: Change "LDAPReferrals off" to actually set the underlying LDAP
26 SDK option to OFF, and introduce "LDAPReferrals default" to take the SDK
27 default, sans rebind authentication callback.
28 [Jan Kaluza <jkaluza AT redhat.com>]
30 *) mod_authz_groupfile, mod_authz_user: Reduce severity of AH01671 and AH01663
31 from ERROR to DEBUG, since these modules do not know what mod_authz_core
32 is doing with their AUTHZ_DENIED return value. [Eric Covener]
34 *) mod_authnz_fcgi: New module to enable FastCGI authorizer
35 applications to authenticate and/or authorize clients.
38 *) mod_auth_basic: Add AuthBasicUseDigestAlgorithm directive to
39 allow migration of passwords from digest to basic authentication.
42 *) core: Add util_fcgi.h and associated definitions and support
43 routines for FastCGI, based largely on mod_proxy_fcgi.
46 *) core: Add ap_log_data(), ap_log_rdata(), etc. for logging buffers.
49 *) mod_unique_id: Use output of the PRNG rather than IP address and
50 pid, avoiding sleep() call and possible DNS issues at startup,
51 plus improving randomness for IPv6-only hosts.
52 [Jan Kaluza <jkaluza redhat.com>]
54 *) core: Log a message at TRACE1 when the client aborts a connection.
57 *) mod_authnz_ldap: Support primitive LDAP servers that do not accept
58 filters, such as "SDBM-backed LDAP" on z/OS, by allowing a special
59 filter "none" to be specified in AuthLDAPURL. [Eric Covener]
61 *) mod_file_cache: mod_file_cache should be able to serve files that
62 haven't had a Content-Type set via e.g. mod_mime. [Eric Covener]
64 *) core: merge AllowEncodedSlashes from the base configuration into
65 virtual hosts. [Eric Covener]
67 *) mod_headers: Add 'setifempty' command to Header and RequestHeader.
70 *) AIX: Install DSO's with "cp" instead of "install" in instdso.sh
73 *) mod_ldap: Retry transient LDAP connection errors when they occur
74 during the authorization stage.
77 *) mod_ldap: Don't keep retrying if a new LDAP connection times out.
80 *) mod_deflate: permit compilation of mod_deflate against a zlib that has
81 been configured with -D Z_PREFIX, which redefines the token "deflate".
84 *) mod_socache_shmcb.c: Remove arbitrary restriction on shared memory size
85 previously limited to 64MB. [Jens Låås <jelaas gmail.com>]
87 *) mod_auth_digest: Use the secret when generating nonces in all cases and
88 not only when AuthName is used in .htaccess files (this change may cause
89 problems if used with round robin load balancers). Don't regenerate the
90 secret on graceful restarts. PR 54637 [Stefan Fritsch]
92 *) ab: Add a new -l parameter in order not to check the length of the responses.
93 This can be usefull with dynamic pages.
94 PR9945, PR27888, PR42040 [<ccikrs1 cranbrook edu>]
96 *) mod_logio: new format-specifier %C (combined) which is the sum of received
98 PR54015 [Christophe Jaillet]
100 *) core: Remove apr_brigade_flatten(), buffering and duplicated code
101 from the HTTP_IN filter, parse chunks in a single pass with zero copy.
102 Reduce memory usage by 48 bytes per request. [Graham Leggett]
104 *) core: Stop the HTTP_IN filter from attempting to write error buckets
105 to the output filters, which is bogus in the proxy case. Create a
106 clean mapping from APR codes to HTTP status codes, and use it where
107 needed. [Graham Leggett]
109 *) mod_proxy: Ensure network errors detected by the proxy are returned as
110 504 Gateway Timout as opposed to 502 Bad Gateway, in order to be
111 compliant with RFC2616 14.9.4 Cache Revalidation and Reload Controls.
113 *) mod_dav: mod_dav overrides dav_fs response on PUT failure. PR 35981
114 [Basant Kumar Kukreja <basant.kukreja sun.com>, Alejandro Alvarez
115 <alejandro.alvarez.ayllon cern.ch>]
117 *) core, mod_ssl: Enable the ability for a module to reverse the sense of
118 a poll event from a read to a write or vice versa. This is a step on
119 the way to allow mod_ssl taking full advantage of the event MPM.
122 *) mod_ldap: LDAP connections used for authentication were not respecting
123 LDAPConnectionPoolTimeout. PR 54587
125 *) core: ap_rgetline_core now pulls from r->proto_input_filters.
127 *) mod_proxy_html: process parsed comments immediately.
128 Fixes bug where parsed comments may be lost. [Nick Kew]
130 *) mod_proxy_html: introduce doctype for HTML 5 [Nick Kew]
132 *) mod_proxy_html: fix typo-bug processing "strict" vs "transitional"
133 HTML/XHTML [Nick Kew]
135 *) core: Add option to add valgrind support. Use it to reduce false positive
136 warnings in mod_ssl. [Stefan Fritsch]
138 *) mod_authn_file, mod_authn_dbd, mod_authn_dbm, mod_authn_socache:
139 Cache the result of the most recent password hash verification for every
140 keep-alive connection. This saves some expensive calculations.
143 *) http: Remove support for Request-Range header sent by Navigator 2-3 and
144 MSIE 3. [Stefan Fritsch]
146 *) core, http: Extend HttpProtocol with an option to enforce stricter HTTP
147 conformance or to only log the found problems. [Stefan Fritsch]
149 *) core: Correctly parse an IPv6 literal host specification in an absolute
150 URL in the request line. [Stefan Fritsch]
152 *) mod_ssl: Add support for OpenSSL configuration commands [Stephen Henson]
156 *) core: Add LogLevelOverride directive that allows to override the
157 loglevel for clients from certain IPs. This also works for things
158 like the SSL handshake where <If> LogLevel ... </If> is evaluated
159 too late. [Stefan Fritsch]
161 *) core: Add new directive Warning to issue warnings from a configuration
162 file. Both Warning and Error now generate a timestamped log message.
165 *) ap_expr: Add SERVER_PROTOCOL_VERSION, ..._MAJOR, and ..._MINOR
166 variables. [Stefan Fritsch]
168 *) core: New directive RegisterHttpMethod for registering non-standard
169 HTTP methods. [Stefan Fritsch]
171 *) core: New directive HttpProtocol which allows to disable HTTP/0.9
172 support. [Stefan Fritsch]
174 *) mod_allowhandlers: New module to forbid specific handlers for specific
175 directories. [Stefan Fritsch]
177 *) mod_systemd: New module, for integration with systemd on Linux.
178 [Jan Kaluza <jkaluza redhat.com>]
180 *) WinNT MPM: Store pid and generation for each thread in scoreboard
181 to allow tracking of threads from exiting children via mod_status
182 or other such mechanisms. [Jeff Trawick]
184 *) mod_ssl: Catch missing or mismatched client cert/key pairs with
185 SSLProxyMachineCertificateFile/Path directives. PR 52212.
186 [Keith Burdis <keith burdis.org>, Joe Orton]
188 *) The following now respect DefaultRuntimeDir/DEFAULT_REL_RUNTIMEDIR:
189 - APIs: ap_log_pid(), ap_remove_pid, ap_read_pid()
190 - core: the scoreboard (ScoreBoardFile), pid file (PidFile), and
192 - mod_cache: thundering herd lock directory
193 - mod_lbmethod_heartbeat, mod_heartmonitor: heartbeat storage file
194 - mod_ldap: shared memory cache
195 - mod_socache_shmcb, mod_socache_dbm: shared memory or dbm for cache
198 *) suexec: Add --enable-suexec-capabilites support on Linux, to use
199 setuid/setgid capability bits rather than a setuid root binary.
202 *) suexec: Add support for logging to syslog as an alternative to logging
203 to a file; configure --without-suexec-logfile --with-suexec-syslog.
206 *) mod_ssl: Add support for TLS Next Protocol Negotiation. PR 52210.
207 [Matthew Steele <mdsteele google.com>]
209 *) cross-compile: allow to provide CC_FOR_BUILD so that gen_test_char will
210 be compiled by the build compiler instead of the host compiler.
211 Also set CC_FOR_BUILD to 'cc' when cross-compilation is detected.
212 PR 51257. [Guenter Knauf]
214 *) core: In maintainer mode, replace apr_palloc with a version that
215 initializes the allocated memory with non-zero values, except if
216 AP_DEBUG_NO_ALLOC_POISON is defined. [Stefan Fritsch]
218 *) mod_policy: Add a new testing module to help server administrators
219 enforce a configurable level of protocol compliance on their
220 servers and application servers behind theirs. [Graham Leggett]
222 *) mod_firehose: Add a new debugging module able to record traffic
223 passing through the server in such a way that connections and/or
224 requests be reconstructed and replayed. [Graham Leggett]
