<lowprio20 gmail.com>]

*) core: Add convenience API for apr_random. [Stefan Fritsch]

*) core: Add MaxRangeOverlaps and MaxRangeReversals directives to control

the number of overlapping and reversing ranges (respectively) permitted

before returning the entire resource, with a default limit of 20.

[Jim Jagielski]

*) mod_ldap: Optional function uldap_ssl_supported(r) always returned false

if called from a virtual host with mod_ldap directives in it. Did not

affect mod_authnz_ldap's usage of mod_ldap. [Eric Covener]

*) mod_filter: Instead of dropping the Accept-Ranges header when a filter

registered with AP_FILTER_PROTO_NO_BYTERANGE is present,

set the header value to "none". [Eric Covener, Ruediger Pluem]

in the case Ranges are being ignored with MaxRanges none.

[Eric Covener]

*) mod_ssl: revamp CRL-based revocation checking when validating

certificates of clients or proxied servers. Completely delegate

CRL processing to OpenSSL, and add a new [Proxy]CARevocationCheck

directive for controlling the revocation checking mode. [Kaspar Brand]

*) core: Add MaxRanges directive to control the number of ranges permitted

before returning the entire resource, with a default limit of 200.

[Eric Covener]

*) mod_cache: Ensure that CacheDisable can correctly appear within

a LocationMatch. [Graham Leggett]

*) mod_cache: Fix the moving of the CACHE filter, which erroneously

stood down if the original filter was not added by configuration.

[Graham Leggett]

*) mod_ssl: improve certificate error logging. PR 47408. [Kaspar Brand]

*) mod_authz_groupfile: Increase length limit of lines in the group file to

16MB. PR 43084. [Stefan Fritsch]

*) mod_ldap: Enable LDAPConnectionTimeout for LDAP toolkits that have

LDAP_OPT_CONNECT_TIMEOUT instead of LDAP_OPT_NETWORK_TIMEOUT, such

as Tivoli Directory Server 6.3 and later. [Eric Covener]

*) mod_ldap: Change default number of retries from 10 to 3, and add

an LDAPRetries and LDAPRetryDelay directives. [Eric Covener]

*) mod_authnz_ldap: Don't retry during authentication, because this just

multiplies the ample retries already being done by mod_ldap. [Eric Covener]

*) configure: Allow to explicitly disable modules even with module selection

'reallyall'. [Stefan Fritsch]

*) mod_rewrite: Check validity of each internal (int:) RewriteMap even if the

RewriteEngine is disabled in server context, avoiding a crash while

referencing the invalid int: map at runtime. PR 50994.

[Ben Noordhuis <info noordhuis nl>]

*) mod_ssl, configure: require OpenSSL 0.9.7 or later. [Kaspar Brand]

*) mod_ssl: remove ssl_toolkit_compat layer. [Kaspar Brand]

*) mod_ssl, configure, ab: drop support for RSA BSAFE SSL-C toolkit.

[Kaspar Brand]

*) mod_usertrack: Run mod_usertrack earlier in the fixups hook to ensure the

cookie is set when modules such as mod_rewrite trigger a redirect. Also

use r->err_headers_out for the cookie, for the same reason. PR29755.

[Sami J. Mäkinen <sjm almamedia fi>, Eric Covener]

*) prefork, worker, event: Make sure crashes are logged to the error log if

httpd has already detached from the console. [Stefan Fritsch]

*) prefork, worker, event: Reduce period during startup/restart where a

successive signal may be lost. PR 43696. [Arun Bhalla <arun shme net>]

*) mod_allowmethods: Correct Merging of "reset" and do not allow an

empty parameter list for the AllowMethods directive. [Rainer Jung]

*) configure: Update selection of modules for 'all' and 'most'. 'all' will

now enable all modules except for example and test modules. Make the

selection for 'most' more useful (including ssl and proxy). Both 'all'

and 'most' will now disable modules if dependencies are missing instead

of aborting. If a specific module is requested with --enable-XXX=yes,

missing dependencies will still cause configure to exit with an error.

[Stefan Fritsch]

*) mod_ldap: Revert the integration of apr-ldap as ap_ldap which was done

in 2.3.13. [Stefan Fritsch]

*) core: For '*' or '_default_' vhosts, use a wildcard address of any

new functions in order to make logging configurable per-module.

[Stefan Fritsch]

*) mod_dir: Add DirectoryIndexRedirect to send an external redirect to

the proper index. [Eric Covener]

*) mod_deflate: Don't try to compress requests with a zero sized body.

[Rainer Jung]

*) mod_socache_dc: add --with-distcache to configure for choosing

the distcache installation directory. [Rainer Jung]

*) mod_socache_dc: use correct build variable MOD_SOCACHE_DC_LDADD

instead of MOD_SOCACHE_LDADD in build macro. [Rainer Jung]

*) mod_lua, mod_deflate: respect platform specific runpath linker

flag. [Rainer Jung]

they have been enabled implicitely. [Rainer Jung]

*) configure: Allow to specify module specific custom linker flags via

the MOD_XXX_LDADD variables. [Rainer Jung]

connections will be accepted per process. [Stefan Fritsch]

*) prefork, worker, event: Rename MaxClients to MaxRequestWorkers which

describes more accurately what it does. [Stefan Fritsch]

*) rotatelogs: Add -p argument to specify custom program to invoke

after a log rotation. PR 51285. [Sven Ulland <sveniu ifi.uio.no>,

Leggett]

*) mod_userdir/mod_alias/mod_vhost_alias: Correctly set DOCUMENT_ROOT,

CONTEXT_DOCUMENT_ROOT, CONTEXT_PREFIX. PR 26052. PR 46198.

[Stefan Fritsch]

*) core: Allow to override document_root on a per-request basis. Introduce

new context_document_root and context_prefix which provide information

about non-global URI-to-directory mappings (from e.g. mod_userdir or

mod_alias) to scripts. PR 49705. [Stefan Fritsch]

*) core: Add <ElseIf> and <Else> to complement <If> sections.

[Stefan Fritsch]

*) mod_ext_filter: Remove DebugLevel option in favor of per-module loglevel.

[Stefan Fritsch]

*) mod_include: Make the "#if expr" element use the new "ap_expr" expression

parser. The old parser can still be used by setting the new directive

SSILegacyExprParser. [Stefan Fritsch]

*) core: Add some features to ap_expr for use by mod_include: a restricted

mode that does not allow to bypass request access restrictions; new

variables DOCUMENT_URI (alias for REQUEST_URI), LAST_MODIFIED; -A as an

alias for -U; an additional data entry in ap_expr_eval_ctx_t for use by

the consumer; an extensible ap_expr_exec_ctx() API that allows to use that

data entry. [Stefan Fritsch]

*) mod_include: Merge directory configs instead of one SSI* config directive

causing all other per-directory SSI* config directives to be reset.

[Stefan Fritsch]

loglevel. [Stefan Fritsch]

*) core: Add ap_regexec_len() function that works with non-null-terminated

strings. PR 51231. [Yehezkel Horowitz <horowity checkpoint com>]

*) mod_authnz_ldap: If the LDAP server returns constraint violation,

don't treat this as an error but as "auth denied". [Stefan Fritsch]

*) mod_proxy_fcgi|scgi: Add support for "best guess" of PATH_INFO

for SCGI/FCGI. PR 50880, 50851. [Mark Montague <mark catseye.org>,

Jim Jagielski]

*) mod_cache: When content is served stale, and there is no means to

revalidate the content using ETag or Last-Modified, and we have

mandated no stale-on-error behaviour, stand down and don't cache.

Saves a cache write that will never be read.

[Graham Leggett]

processes. Add end_generation hook for notification when the last

MPM child of a generation exits. [Jeff Trawick]

*) mod_ldap: Make LDAPSharedCacheSize 0 create a non-shared-memory cache per

process as opposed to disabling caching completely. This allows to use

the non-shared-memory cache as a workaround for the shared memory cache

not being available during graceful restarts. PR 48958. [Stefan Fritsch]

*) Add new ap_reserve_module_slots/ap_reserve_module_slots_directive API,

necessary if a module (like mod_perl) registers additional modules late

in the startup phase. [Stefan Fritsch]

*) core: Prevent segfault if DYNAMIC_MODULE_LIMIT is reached. PR 51072.

[Torsten Förtsch <torsten foertsch gmx net>]

directory in addition to per server, making them work from within

a LocationMatch. [Graham Leggett]

restart, such that processes of the previous generation were not

observable. [Jeff Trawick]

Changes with Apache 2.3.11

*) mod_win32: Added shebang check for '! so that .vbs scripts work as CGI.

were not active during server startup but got enabled later during a

graceful restart. [Stefan Fritsch]

*) core: Create new ap_state_query function that allows modules to determine

if the current configuration run is the initial one at server startup,

and if the server is started for testing/config dumping only.

[Stefan Fritsch]

*) mod_proxy: Runtime configuration of many parameters for existing

balancers via the balancer-manager. [Jim Jagielski]

*) mod_proxy: Runtime addition of new workers (BalancerMember) for existing

balancers via the balancer-manager. [Jim Jagielski]

output fragmented into many buckets, such as chunked HTTP responses.

[Joe Orton]

*) core: Apply <If> sections to all requests, not only to file base requests.

Allow to use <If> inside <Directory>, <Location>, and <Files> sections.

The merging of <If> sections now happens after the merging of <Location>

sections, even if an <If> section is embedded inside a <Directory> or

<Files> section. [Stefan Fritsch]

*) mod_proxy: Refactor usage of shared data by dropping the scoreboard

and using slotmem. Create foundation for dynamic growth/changes of

members within a balancer. Remove BalancerNonce in favor of a

per-balancer 'nonce' parameter. [Jim Jagielski]

PR: 47022 [Jordi Prats <jordi prats gmail com>, Stefan Fritsch]

*) mpm_prefork: Fix ap_mpm_query results for AP_MPMQ_MAX_DAEMONS and

AP_MPMQ_MAX_THREADS.

*) mod_authz_core: Fix bug in merging logic if user-based and non-user-based

authorization directives were mixed. [Stefan Fritsch]

*) mod_authn_socache: change directive name from AuthnCacheProvider

to AuthnCacheProvideFor. The term "provider" is overloaded in

this module, and we should avoid confusion between the provider

of a backend (AuthnCacheSOCache) and the authn provider(s) for

which this module provides cacheing (AuthnCacheProvideFor).

[Nick Kew]

*) mod_proxy_http: Allocate the fake backend request from a child pool

of the backend connection, instead of misusing the pool of the frontend

request. Fixes a thread safety issue where buckets set aside in the

backend connection leak into other threads, and then disappear when

the frontend request is cleaned up, in turn causing corrupted buckets

to make other threads spin. [Graham Leggett]

*) mod_ssl: Change the format of the SSL_{CLIENT,SERVER}_{I,S}_DN variables

to be RFC 2253 compatible, convert non-ASCII characters to UTF8, and

escape other special characters with backslashes. The old format can

still be used with the LegacyDNStringFormat argument to SSLOptions.

[Sönke Tesch <st kino-fahrplan.de>]

*) core: When exporting request headers to HTTP_* environment variables,

drop variables whose names contain invalid characters. Describe in the

docs how to restore the old behaviour. [Malte S. Stretz <mss apache org>]

*) core: When selecting an IP-based virtual host, favor an exact match for

the port over a wildcard (or omitted) port instead of favoring the one

that came first in the configuration file. [Eric Covener]

*) core: Overlapping virtual host address/port combinations now implicitly

enable name-based virtual hosting for that address. The NameVirtualHost

directive has no effect, and _default_ is interpreted the same as "*".

[Eric Covener]

*) core: In the absence of any Options directives, the default is now

"FollowSymlinks" instead of "All". [Igor Galić]

*) rotatelogs: Add -e option to write logs through to stdout for optional

expression. [Stefan Fritsch]

*) mod_proxy: Fix ProxyPassInterpolateEnv directive. PR 50292.

[Stefan Fritsch]

*) suEXEC: Add Suexec directive to disable suEXEC without renaming the

binary (Suexec Off), or force startup failure if suEXEC is required

but not supported (Suexec On). Change SuexecUserGroup to fail

startup instead of just printing a warning if suEXEC is disabled.

[Jeff Trawick]

*) core: Add Error directive for aborting startup or htaccess processing

with a specified error message. [Jeff Trawick]

*) mod_rewrite: Fix the RewriteEngine directive to work within a

location. Previously, once RewriteEngine was switched on globally,

it was impossible to switch off. [Graham Leggett]

*) core, mod_include, mod_ssl: Move the expression parser derived from

mod_include back into mod_include. Replace ap_expr with a parser

derived from mod_ssl's parser. Make mod_ssl use the new parser. Rework

and functions. [Stefan Fritsch]

*) core: Do the hook sorting earlier so that the hooks are properly sorted

or not cache based on the buckets present in the brigade, such as the

presence of a FILE bucket.

[Graham Leggett]

*) mod_authz_core: Allow authz providers to check args while reading the

*) mod_include: Reinstate support for UTF-8 character sets by allowing a

variable being echoed or set to be decoded and then encoded as separate

steps. PR47686 [Graham Leggett]

*) mod_cache: Add a discrete commit_entity() provider function within the

mod_cache provider interface which is called to indicate to the

provider that caching is complete, giving the provider the opportunity

to commit temporary files permanently to the cache in an atomic

fashion. Replace the inconsistent use of error cleanups with a formal

set of pool cleanups attached to a subpool, which is destroyed on error.

[Graham Leggett]

*) mod_cache: Change the signature of the store_body() provider function

within the mod_cache provider interface to support an "in" brigade

and an "out" brigade instead of just a single input brigade. This

gives a cache provider the option to consume only part of the brigade

passed to it, rather than the whole brigade as was required before.

This fixes an out of memory and a request timeout condition that would

occur when the original document was a large file. Introduce

CacheReadSize and CacheReadTime directives to mod_disk_cache to control

the amount of data to attempt to cache at a time. [Graham Leggett]

*) mod_cache: Check the request to determine whether we are allowed

to return cached content at all, and respect a "Cache-Control:

no-cache" header from a client. Previously, "no-cache" would

behave like "max-age=0". [Graham Leggett]

*) mod_cache: Use a proper filter context to hold filter data instead

*) sendfile_nonblocking() takes the _brigade_ as an argument, gets

the first bucket from the brigade, finds it not to be a FILE

bucket and barfs. The fix is to pass a bucket rather than a brigade.

[Niklas Edmundsson <nikke acc.umu.se>]

*) mod_rewrite: support rewritemap by SQL query [Nick Kew]

*) ap_get_server_version() has been removed. Third-party modules must

now use ap_get_server_banner() or ap_get_server_description().

[Jeff Trawick]

*) All MPMs: Introduce a check_config phase between pre_config and

open_logs, to allow modules to review interdependent configuration

directive values and adjust them while messages can still be logged

to the console. Handle relevant MPM directives during this phase

and format messages for both the console and the error log, as

appropriate. [Chris Darroch]

*) core: Do not allow internal redirects like the DirectoryIndex of mod_dir

to circumvent the symbolic link checks imposed by FollowSymLinks and

SymLinksIfOwnerMatch. [Nick Kew, Ruediger Pluem, William Rowe]

*) New SSLLogLevelDebugDump [ None (default) | IO (not bytes) | Bytes ]

configures the I/O Dump of SSL traffic, when LogLevel is set to Debug.

The default is none as this is far greater debugging resolution than

the typical administrator is prepared to untangle. [William Rowe]

*) mod_disk_cache: If possible, check if the size of an object to cache is

within the configured boundaries before actually saving data.

[Niklas Edmundsson <nikke acc.umu.se>]

*) Worker and event MPMs: Remove improper scoreboard updates which were

performed in the event of a fork() failure. [Chris Darroch]

*) Add support for fcgi:// proxies to mod_rewrite.

[Markus Schiegl <ms schiegl.com>]

*) Remove incorrect comments from scoreboard.h regarding conditional

loading of worker_score structure with mod_status, and remove unused

definitions relating to old life_status field.

[Chris Darroch <chrisd pearsoncmg.com>]

*) Remove allocation of memory for unused array of lb_score pointers

in ap_init_scoreboard(). [Chris Darroch <chrisd pearsoncmg.com>]

*) Add mod_proxy_fcgi, a FastCGI back end for mod_proxy.

[Garrett Rooney, Jim Jagielski, Paul Querna]

*) Event MPM: Fill in the scoreboard's tid field. PR 38736.

[Chris Darroch <chrisd pearsoncmg.com>]

*) mod_charset_lite: Remove Content-Length when output filter can

invalidate it. Warn when input filter can invalidate it.

[Jeff Trawick]

*) Authz: Add the new module mod_authn_core that will provide common

authn directives such as 'AuthType', 'AuthName'. Move the directives

'AuthType' and 'AuthName' out of the core module and merge mod_authz_alias

into mod_authn_core. [Brad Nicholes]

*) Authz: Move the directives 'Order', 'Allow', 'Deny' and 'Satisfy'

into the new module mod_access_compat which can be loaded to provide

support for these directives.

[Brad Nicholes]

*) Authz: Move the 'Require' directive from the core module as well as

add the directives '<SatisfyAll>', '<SatisfyOne>', '<RequireAlias>'

and 'Reject' to mod_authz_core. The new directives introduce 'AND/OR'

logic into the authorization processing. [Brad Nicholes]

*) Authz: Add the new module mod_authz_core which acts as the

authorization provider vector and contains common authz

directives. [Brad Nicholes]

*) Authz: Renamed mod_authz_dbm authz providers from 'group' and

'file-group' to 'dbm-group' and 'dbm-file-group'. [Brad Nicholes]

*) Authz: Added the new authz providers 'env', 'ip', 'host', 'all' to handle

host-based access control provided by mod_authz_host and invoked

through the 'Require' directive. [Brad Nicholes]

*) Authz: Convert all of the authz modules from hook based to

provider based. [Brad Nicholes]

*) mod_cache: Add CacheMinExpire directive to set the minimum time in

seconds to cache a document.

[Brian Akins <brian.akins turner.com>, Ruediger Pluem]

*) mod_authz_dbd: SQL authz with Login/Session support [Nick Kew]

*) Fix typo in ProxyStatus syntax error message.

[Christophe Jaillet <christophe.jaillet wanadoo.fr>]

*) Asynchronous write completion for the Event MPM. [Brian Pane]

*) Added an End-Of-Request bucket type. The logging of a request and

the freeing of its pool are now done when the EOR bucket is destroyed.

This has the effect of delaying the logging until right after the last

of the response is sent; ap_core_output_filter() calls the access logger

indirectly when it destroys the EOR bucket. [Brian Pane]

*) Rewrite of logresolve support utility: IPv6 addresses are now supported

and the format of statistical output has changed. [Colm MacCarthaigh]

*) Rewrite of ap_coreoutput_filter to do nonblocking writes [Brian Pane]

*) Added new connection states for handler and write completion

[Brian Pane]

*) mod_cgid: Refuse to work on Solaris 10 due to OS bugs. PR 34264.

[Justin Erenkrantz]

*) Teach mod_ssl to use arbitrary OIDs in an SSLRequire directive,

allowing string-valued client certificate attributes to be used for

access control, as in: SSLRequire "value" in OID("1.3.6.1.4.1.18060.1")
