Isolated the SSL functionality to mod_ldap rather than speading it
across mod_auth_ldap and mod_ldap. Also added LDAPTrustedCA
and LDAPTrustedCAType directives to mod_ldap to allow for a more
common method of specifying the SSL certificate.
[Dave Ward, Brad Nicholes]
*) Fixed mod_ssl's SSLCertificateChain initialization to no longer
skip the first cert of the chain by default. This misbehavior
was introduced in 2.0.34. PR 14560 [Madhusudan Mathihalli]
*) mod_cgi, mod_cgid, mod_ext_filter: Log errors when scripts cannot
be started on Unix because of such problems as bad permissions,
bad shebang line, etc. [Jeff Trawick]
*) Fix 64-bit problem in mod_ssl input logic.
*) Fix potential memory leaks in mod_deflate on malformed data. PR 16046.
[Justin Erenkrantz]
*) Rewrite ap_xml_parse_input to use bucket brigades. PR 16134.
[Justin Erenkrantz]
*) Fix segfault which occurred when a section in an included
configuration file was not closed. PR 17093. [André Malo]
*) Enhance the behavior of mod_isapi's WriteClient() callback to
provide better emulation for isapi modules that presume that the
first WriteClient() call may send status and headers. An example
of WriteClient() abuse is the foxisapi module, which relies on
that assumpion and now works. [William Rowe, Milan Kosina]
*) Check the return value of ap_run_pre_connection(). So if the
pre_connection phase fails (without setting c->aborted)
ap_run_process_connection is not executed. [Stas Bekman]
*) Fixed a problem with mod_ldap which caused it to fault when caching
was disabled. Needed to make sure that the code did not
attempt to use the cache if it didn't exist. Also fixed some memory
leaks which were due to not releasing LDAP resources on error
conditions. [Brad Nicholes]
*) Hook mod_proxy's fixup before mod_rewrite's fixup, so that by
mod_rewrite proxied URLs will not be escaped accidentally by
mod_proxy's fixup. PR 16368 [André Malo]
*) While processing filters on internal redirects, remember seen EOS
buckets also in the request structure of the redirect issuer(s). This
prevents filters (such as mod_deflate) from adding garbage to the
response. PR 14451. [André Malo]
*) suexec: Be more pedantic when cleaning environment. Clean it
immediately after startup. PR 2790, 10449.
*) Fix apxs to insert LoadModule directives only outside of sections.
PR 8712, 9012. [André Malo]
*) Fix suexec compile error under SUNOS4, where strerror() doesn't
exist. PR 5913, 9977.
*) Fix If header parsing when a non-mod_dav lock token is passed to it.
PR 16452. [Justin Erenkrantz]
*) mod_auth_digest no longer tries to guess AuthDigestDomain, if it's
not specified. Now it assumes "/" as already documented. PR 16937.
[André Malo]
*) Try to log an error if a piped log program fails. Try to
restart a piped log program in more failure situations. Fix an
existing problem with error handling in piped_log_spawn(). Use
new APR apr_proc_create() features to prevent Apache from starting
on Unix* in most cases where a piped log program can be started,
and add log messages for the other situations. *Other platforms
already failed Apache initialization if a piped log program
couldn't be started. PR 15761 [Jeff Trawick]
*) Fix mod_cern_meta to not create empty metafiles when the
metafile searched for does not exist. PR 12353
*) Introduce debugging symbols for Win32 release builds, both .pdb
and .dbg files (older debuggers and Dr. Watson-type utilities
on WinNT or Win9x don't support the newer .pdb flavor.)
[Allen Edwards, William Rowe]
*) Fix bug where 'Satisfy Any' without an AuthType lost all MIME
information (and more). Related to PR 9076. [André Malo]
*) mod_file_cache: fix segfault serving mmaped cached files.
[Bill Stoddard]
*) mod_file_cache: fixed a segfault when multiple MMapFile directives
were used. PR 16313. [Cliff Woolley]
*) Fix a nasty segfault in mmap_bucket_setaside() caused by passing
an incompatible pointer type to mmap_bucket_destroy(void*).
*) Enable the -n name parameter on NetWare to allow the
administrator to rename the Apache console screen
[Brad Nicholes]
*) Fixed piped access logs on Win32 by disabling OTHER_CHILD
support by default in APR. More development is required
to deploy OTHER_CHILD on Win32. [William Rowe]
*) Use saner default config values for suexec. PR 15713.
*) mod_rewrite: Allow "RewriteEngine Off" even if no "Options FollowSymlinks"
(or SymlinksIfOwnermatch) is set. PR 12395. [André Malo]
*) apxs: Include any special APR ld flags when linking the DSO.
This resolves problems on AIX when building a DSO with apxs+gcc.
[Jeff Trawick]
*) Added character set support to mod_auth_LDAP to allow it to
convert extended characters used in the user ID to UTF-8
before authenticating against the LDAP directory. The new
directive AuthLDAPCharsetConfig is used to specify the config
file that contains the character set conversion table.
[Brad Nicholes]
*) Don't remove the Content-Length from responses in mod_proxy
PR: 8677 [Brian Pane]
*) Ensure LDAP version is set to v3 on every bind. PR 14235.
*) Fix mod_ldap to open an existing shared memory file should one
Graham Leggett]
*) Fix the ulimit command used by apachectl on Tru64. PR 13609.
*) Change the ulimit command used by apachectl on AIX so that it
works in all locales. [Jeff Trawick]
*) mod_ext_filter: Fix a problem building argument lists which
occasionally caused exec to fail. PR 15491. [Jeff Trawick]
Changes with Apache 2.0.44
*) mod_autoindex: Bring forward the IndexOptions IgnoreCase option
from Apache 1.3. PR 14276
*) mod_mime: Workaround to prevent a segfault if r->filename=NULL
[Brian Pane]
*) Reorder the definitions for mod_ldap and mod_auth_ldap within
config.m4 to make sure the parent mod_ldap is defined first.
This ensures that mod_ldap comes before mod_auth_ldap in the
httpd.conf file, which is necessary for mod_auth_ldap to load.
PR 14256 [Graham Leggett]
*) Fix the building of cgi command lines when the query string
Jeff Trawick]
*) Rename CacheMaxStreamingBuffer to MCacheMaxStreamingBuffer. Move
implementation of MCacheMaxStreamingBuffer from mod_cache to
mod_mem_cache. MCacheMaxStreamingBuffer now defaults to the
lesser of 100,000 bytes or MCacheMaxCacheObjectSize. This should
eliminate the need for explicitly coding MCacheMaxStreamingBuffer
in most configurations. [Bill Stoddard]
*) mod_cache: Fix PR 15113, a core dump in cache_in_filter when
a redirect occurs. The code was passing a format string and
integer to apr_pstrcat. Changed to apr_psprintf.
[Paul J. Reder]
*) Replace APU_HAS_LDAPSSL_CLIENT_INIT with APU_HAS_LDAP_NETSCAPE_SSL
as set by apr-util in util_ldap.c. This should allow mod_ldap
to work with the Netscape/Mozilla LDAP library. [Øyvin Sømme
*) Fix critical bug in new --enable-v4-mapped configure option
implementation which broke IPv4 listening sockets on some
*) mod_setenvif: Fix BrowserMatchNoCase support for non-regex
*) build: './configure && make' now works without an in-tree
apr and apr-util. [Wilfredo Sanchez]
*) mod_negotiation: Set the appropriate mime response headers
(Content-Type, charset, Content-Language and Content-Encoding)
for negotated type-map "Body:" responses (such as the error
*) mod_log_config: Allow '%%' escaping in CustomLog format
strings to insert a literal, single '%'.
*) mod_autoindex: AddDescription directives for directories
now work as in Apache 1.3, where no trailing '/' is
specified on the directory name. Previously, the trailing
'/' *had* to be specified, which was incompatible with
Apache 1.3. PR 7990 [Jeff Trawick]
*) Fix for PR 14556. The expiry calculations in mod_cache were
trying to perform "now + ((date - lastmod) * factor)" where
date == lastmod resulting in "now + 0". The code now follows
the else path (using the default expiration) if date is
*) Use AP_DECLARE in the debug versions of ap_strXXX in case the
default calling convention is not the same as the one used by
*) mod_cache: Don't cache response header fields designated
as hop-by-hop headers in HTTP/1.1 (RFC 2616 Section 13.5.1).
*) mod_cgid: Handle environment variables containing newlines.
*) Move mod_ext_filter out of experimental and into filters.
[Jeff Trawick]
*) Fixed a memory leak in mod_deflate with dynamic content.
*) Add --[enable|disable]-v4-mapped configure option to control
whether or not Apache expects to handle IPv4 connections
on IPv6 listening sockets. Either setting will work on
systems with the IPV6_V6ONLY socket option. --enable-v4-mapped
must be used on systems that always allow IPv4 connections on
IPv6 listening sockets. PR 14037 (Bugzilla), PR 7492 (Gnats)
[Jeff Trawick]
*) This fixes a problem where the underlying cache code
indicated that there was one more element on the cache
than there actually was. This happened since element 0
exists but is not used. This code allocates the correct
number of useable elements and reports the number of
actually used elements. The previous code only allowed
MCacheMaxObjectCount-1 objects to be stored in the
cache. [Paul J. Reder]
