1.3b3 announcement as I'll send it
-----BEGIN PGP SIGNED MESSAGE-----
Apache 1.3beta3 Released
- ------------------------
The Apache Group is pleased to announce the release of the 1.3b3 version
of Apache, the latest beta release of the Apache web server.
Apache 1.3 offers numerous enhancements, improvements and performance
boosts over the 1.2 code base. The most visible and noteworthy addition
is the ability to run Apache under Windows 95 and NT (known as the
``Win32'' port).
Apache 1.3b3 under both Win32 and UNIX has undergone extensive testing,
and is much improved over the previous 1.3b2 release. In particular, the
1.3b2 release for Win32 was considered a ``developer's version.'' We feel
confident that the Win32 port is ready for a wider audience, and with that
in mind, we are providing pre-compiled executables for the Win32 platform,
as well as a true Win32 environment Installer (InstallShield). This is,
however, still a beta release and there are known issues that will be
fixed before the final 1.3 release.
Please be sure to read the CHANGES file and the "New Features with Apache
1.3" document (at http://www.apache.org/docs/new_features_1_3.html).
This is particularly important if you are using non-IP based virtual hosts.
Apache has been the most popular web server on the Internet since April
of 1996. The September 1997 WWW server site survey by Netcraft (see:
http://www.netcraft.co.uk/Survey/) found that more web servers were
using Apache than any other software. Apache and its derivatives are run
on over 49% of all web domains on the Internet.
The Apache project has been organized in an attempt to answer some of
the concerns regarding active development of a public domain HTTP server
for UNIX. The goal of this project is to provide a secure, efficient and
extensible server which provides HTTP services in sync with the current
HTTP standards.

Changes with Apache 1.3b3
*) WIN32: Work around brain-damaged spawn calls that can't deal
with spaces and slashes. [Ben Laurie]
*) WIN32: Fix the code so CGIs can use socket calls on Windows.
The problem was that certain undocumented environment variables
needed for sockets to work under Win32 were not being passed.
[Frank Faubert <fr...@sane.com>]
*) Add a "-V" command line flag to the httpd binary. This
flag shows some of the defines that Apache was compiled with.
It is useful for debugging purposes. [Martin Kraemer]
*) Start separating the ap_*() routines into their own library, so they
can be used by items in src/support among other things. PR#512, 905,
1252, 1308 [Ken Coar]
*) Give a more informative error when no AuthType is set.
[Lars Eilebrecht]
*) Remove strtoul() use from mod_proxy because it isn't available
on all platforms. [Marc Slemko] PR#1214
*) WIN32: Some Win32 systems terminated all responses after 16 kB.
This turns out to be a bug in Winsock - select() doesn't always
return the correct status. [Ben Laurie]
*) Directives owned by http_core can now use the new check_cmd_context()
routine to ensure that they're not being used within a container
(e.g., <Directory>) where they're invalid. [Martin Kraemer]
*) PORT: Recent changes made it necessary to add explicit prototype
for fgetc() and fgets() on SunOS 4.x. [Martin Kraemer, Ben Hyde]
*) It was necessary to distinguish between resources which are
allocated in the parent, for cleanup in the parent, and resources
which are allocated in each child, for cleanup in each child.
A new pool was created which is passed to the module child_init
and child_exit functions; modules are free to register per-child
cleanups there. This fixes a bug with reliable piped logs.
[Dean Gaudet]
*) mod_autoindex wasn't displaying the ReadmeName file at the bottom
unless it was also doing FancyIndexes, but it displayed the
HeaderName file at the top under all circumstances. It now shows
the ReadmeName file for simple indices, too, as it should. PR#1373
[Ken Coar]
*) http_core was mmap()ing even in cases where it wasn't going to
read the file. [Ben Hyde <bh...@gensym.com>]
*) Complete rewrite ;-) of mod_rewrite's URL rewriting engine:
Now the rewriting engine (the heart of mod_rewrite) is organized more
straight-forward, first time well documented and reduced to the really
essential parts. All redundant cases were stripped off and processing now
is the same for both per-server and per-directory context with only a
minimum difference (the prefix stripping in per-dir context). As a
side-effect some subtle restrictions and two recently discovered problems
are gone: Wrong escaping of QUERY_STRING on redirects in per-directory
context and restrictions on the substitution URL on redirects.
Additionally some minor source cleanups were done.
[Ralf S. Engelschall]
*) Lars Eilebrecht wrote a whole new set of Apache Vhost Internals
documentation, examples, explanations and caveats. They live in a new
subdirectory htdocs/manual/vhost/. [Lars Eilebrecht <sf...@unix-ag.org>]
*) If ap_slack fails to allocate above the low slack line it's a good
indication that further problems will occur; it's a better indication
than many external libraries give us when we actually run out of
descriptors. So report it to the user once per restart.
[Dean Gaudet] PR#1181
*) Change mod_include and mod_autoindex to use Y2K-safe date formats
by default. [Ken Coar]
*) Add a "SuppressColumnSorting" option to the IndexOptions list,
which will keep the column heading from being links for sorting
the display. [Ken Coar, suggested by Brian Tiemann <bt...@pacific.net>]
PR #1261
*) PORT: Update the LynxOS port. [Marius Groeger <ma...@sysgo.de>]
*) Fix logic error when issuing a mmap() failed message
with a non-zero MMAP_THRESHOLD.
[David Chambers <da...@flosun.salk.edu>] PR#1294
*) Preserve handler value on ProxyPass'ed requests by not
calling find_types on a proxy'd request; fixes problems
where some ProxyPass'ed URLs weren't actually passed
to the proxy.
[Lars Eilebrecht] PR#870
*) Fix a byte ordering problem in mod_access which prevented
the old-style syntax (i.e. "a.b.c." to match a class C)
from working properly. [Dean Gaudet] PR#1248, 1328, 1384
*) Fix problem with USE_FLOCK_SERIALIZED_ACCEPT not working
properly. Each child needs to open the lockfile instead
of using the passed file-descriptor from the parent. PR#1056
*) Fix the error logging in mod_cgi; the recent error log changes
introduced a bug that prevented it from working correctly.
[M.D.Parker] PR#1352
*) Default to USE_FCNTL_SERIALIZED_ACCEPT on HPUX to properly
handle multiple Listen directives. [Marc Slemko] PR#872
*) Inherit a bugfix to fnmatch.c from FreeBSD sources.
["[KOI8-R] aNDREJ ~ERNOW" <ac...@nagual.pp.ru>] PR#1311
*) When a configuration parse complained about a bad directive,
the logger would use whatever (unrelated) value was in errno.
errno is now forced to EINVAL first in this case. [Ken Coar]
*) A sed command in the Configure script pushed the edge of POSIXness,
breaking on some systems. [Bhaba R.Misra <sy...@vt.edu>] PR#1368
*) Solaris >= 2.5 was totally broken due to a mess up using pthread
mutexes. [Roy Fielding, Dean Gaudet]
*) OS/2 Port updated; it should be possible to build OS/2 from the same
sources as Unix now. [Brian Havard <br...@kheldar.apana.org.au>]
*) Fix a year formatting bug in mod_usertrack.
[Paul Eggert <eg...@twinsun.com>] PR#1342
*) A mild SIGTERM/SIGALRM race condition was eliminated.
[Dean Gaudet] PR#1211
*) Warn user that default path has changed if /usr/local/etc/httpd
is found on the system. [Lars Eilebrecht]
*) Various mod_mime_magic bug fixes and cleanups: Uncompression
should work, it should work on WIN32, and a few resource
leaks and abort conditions are fixed.
[Dean Gaudet] PR#1205
*) PORT: On AIX 1.x files can't be named '@', fix the proxy cache
to use '%' instead of '@' in its encodings.
[David Schuler <sc...@btv.ibm.com>] PR#1317
*) Improve the warning message generated when the "server is busy".
[Dean Gaudet] PR#1293
*) PORT: All ports which don't otherwise define DEF_WANTHSREGEX will
get Spencer regex by default. This is to avoid having to
discover bugs in operating system libraries. [Dean Gaudet]
*) PORT: "Fix" PR#467 by generating warnings on systems which we have
not been able to get working USE_*_SERIALIZED_ACCEPT settings for.
Document this a bit more in src/PORTING. [Dean Gaudet] PR#467
*) Ensure that one copy of config warnings makes it to the
error_log. [Dean Gaudet]
*) Invent new structure and associated methods to handle config file
reading. Add "custom" hook to use config file cfg_getline() on
something which is not a FILE* [Martin Kraemer]
*) Make single-exe Windows install. [Ben Laurie and Eric Esselink]
*) WIN32: Make CGI work under Win95. [Ben Laurie and Paul Sutton]
*) WIN32: Make index.html and friends work under Win95. [Ben Laurie]
*) PORT: Solaris 2.4 needs Spencer regex, the system regex is broken.
[John Line <jm...@cam.ac.uk>] PR#1321
*) Default pathname has been changed everywhere to /usr/local/apache
[Sameer <sa...@c2.net>]
*) PORT: AIX now uses USE_FCNTL_SERIALIZED_ACCEPT.
[David Bronder <Da...@uiowa.edu>] PR#849
*) PORT: i386 AIX does not have memmove.
[David Schuler <sc...@btv.ibm.com>] PR#1267
*) PORT: HPUX now defaults to using Spencer regex.
[Philippe Vanhaesendonck <pv...@be.oracle.com>,
Omar Del Rio <al...@academ01.lag.itesm.mx>] PR#482, 1246
*) PORT: Some versions of NetBSD don't automatically define
__NetBSD__. Workaround by defining NETBSD.
[Chris Craft <cc...@cncc.cc.co.us>] PR#977
*) PORT: UnixWare 2.x requires -lgen for syslog.
[Hans Snijder <hs...@meganet.nl>] PR#1249
*) PORT: ULTRIX appears to not have syslog.
[Lars Eilebrecht <La...@unix-ag.org>]
*) PORT: Basic Gemini port (treat it like unixware212).
["Pavel Yakovlev (Paul McHacker)" <ha...@tomcat.olly.ru>]
*) PORT: All SVR4 systems now use NET_SIZE_T = size_t, and
use HAVE_SHMGET.
[Martin Kraemer]
*) Various improvements in detecting config file errors (missing closing
directives for <Directory>, <Files> etc. blocks, prohibiting global
server settings in <VirtualHost> blocks, flagging unhandled multiple
arguments to <Directory>, <Files> etc.)
[Martin Kraemer]
*) Add support to suexec wrapper program for mod_unique_id's UNIQUE_ID
variable to provide this one to suexec'd CGIs, too.
[M.D.Parker <md...@netcom.com>] PR#1284
*) New support tool: src/support/split-logfile, a sample Perl script which
splits up a combined access log into separate files based on the
name of the virtual host (listed first in the log records by "%v").
[Ken Coar]
Changes with Apache 1.3b2 (there is no 1.3b1)
*) TestCompile was not passing $LIBS [Dean Gaudet]
*) Makefile.tmpl was not using $CFLAGS in the link phase.
[Martin Kraemer]
*) Add debugging code to alloc.c. Defining ALLOC_DEBUG provides a
rudimentary memory debugger which can be used on live servers with
low impact -- it sets all allocated and freed memory bytes to 0xa5.
Defining ALLOC_USE_MALLOC will cause the alloc code to use malloc()
and free() for each object. This is far more expensive and should
only be used for testing with tools such as Electric Fence and
Purify. See main/alloc.c for more details. [Dean Gaudet]
*) Configure uses a sh trap and didn't set its exitcode properly.
[Dean Gaudet] PR#1159
*) Yet another vhost revamp. Add the NameVirtualHost directive which
explicitly lists the ip:port pairs that are to be used for name-vhosts.
From a given ip:port, regardless what the Host: header is, you can
only reach the vhosts defined on that ip:port. The precedence of
vhosts was reversed to match other precedences in the config --
the earlier vhosts override the later vhosts. All vhost matching was
moved into http_vhost.[ch]. [Dean Gaudet]
*) ap_inline can be used to force inlining. GNUC __attribute__() can
be used for whatever reason is appropriate (i.e. format() warnings
for printf style functions). Both are enabled only with
gcc >= 2.7.x (so that we have fewer support issues with older
versions). [Dean Gaudet]
*) Fix support for Proxy Authentication (we were testing the response
status too early). [Marc Slemko]
*) CoreDumpDirectory directive directs where the core file is
written when a SIGSEGV, SIGBUS, SIGABORT or SIGABRT are
received. [Marc Slemko, Dean Gaudet]
*) PORT: Support for Atari MINT.
[Jan Paul Schmidt <Ja...@mni.fh-giessen.de>]
*) When booting, apache will now detach itself from stdin, stdout,
and stderr. stderr will not be detached until after the config
files have been read so you will be able to see initial error
messages. After that all errors are logged in the error_log.
This makes it more convenient to start apache via rsh, ssh,
or crontabs. [Dean Gaudet] PR#523
*) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
Also removed the auto-generated link to www.apache.org that was the
source of so many misdirected bug reports. [Roy Fielding, Marc Slemko]
*) send_fb would not detect aborted connections in some situations.
[Dean Gaudet]
*) mod_include would use uninitialized data when parsing certain
expressions involving && and ||. [Brian Slesinsky] PR#1139
*) mod_imap should only handle GET methods. [Jay Bloodworth]
*) suexec.c wouldn't build without -DLOG_EXEC. [Jason A. Dour]
*) mod_autoindex improperly counted &escapes; as more than one
character in the description. It also improperly truncated
descriptions that were exactly the maximum length.
[Martin Kraemer]
*) RedirectMatch was not properly escaping the result (PR#1155). Also
"RedirectMatch /advertiser/(.*) $1" is now permitted.
[Dean Gaudet]
*) mod_include now uses symbolic names to check for request success
and return HTTP errors, and correctly handles all types of
redirections (previously it only did temporary redirect correctly).
[Ken Coar, Roy Fielding]
*) mod_userdir was modifying r->finfo in cases where it wasn't setting
r->filename. Since those two are meant to be in sync with each other
this is a bug. ["Paul B. Henson" <he...@intranet.csupomona.edu>]
*) PORT: Support Unisys SVR4, whose uname returns mostly useless data.
["Kaufman, Steven E" <St...@unisys.com>]
*) Inetd mode (which is buggy) uses timeouts without having setup the
jmpbuffer. [Dean Gaudet] PR#1064
*) Work around problem under Linux where a child will start looping
reporting a select error over and over.
[Rick Franchuk <ri...@transpect.net>] PR#1107
*) Fixed error in proxy_util.c when looping through multiple host IP
addresses. [Lars Eilebrecht] PR#974
*) If BUFFERED_LOGS is defined then mod_log_config will do atomic
buffered writes -- that is, it will buffer up to PIPE_BUF (i.e. 4k)
bytes before writing, but it will never split a log entry across a
buffer boundary. [Dean Gaudet]
*) API: the short_score record has been split into two pieces, one which
the parent writes on, and one which the child writes on. As part of
this change the get_scoreboard_info() function was removed, and
scoreboard_image was exported. This change fixes a race condition
in file based scoreboard systems, and speeds up changes involving the
scoreboard in earlier 1.3 development. [Dean Gaudet]
*) API: New register_other_child() API (see http_main.h) which allows
modules to register children with the parent for maintenance. It
is disabled by defining NO_OTHER_CHILD. [Dean Gaudet]
*) API: New piped_log API (see http_log.h) which implements piped logs,
and will use register_other_child to implement reliable piped logs
when it is available. The reliable piped logs part can be disabled
by defining NO_RELIABLE_PIPED_LOGS. At the moment reliable piped
logs is only available on Unix. [Dean Gaudet]
*) API: set_last_modified() broken into set_last_modified(), set_etag(), and
meets_conditions(). This allows conditional HTTP selection to be
handled separately from the storing of the header fields, and provides
the ability for CGIs to set their own ETags for conditional checking.
[Ken Coar, Roy Fielding] PR#895
*) Changes to mod_log_config to allow naming of format strings.
Format nicknames are defined with "LogFormat fmt nickname", and can
be used with "LogFormat nickname" and "CustomLog logtarget nickname".
[Ken Coar]
*) New module, "mod_speling", which can help find files even when
the URL is slightly misspelled. [Martin Kraemer, Alexei Kosut]
*) API: New function child_terminate() triggers the child process to
exit, while allowing the child finish what it needs to for the
current request first.
[Doug MacEachern, Alexei Kosut]
*) Windows now defaults to using full status reports with mod_status.
[Alexei Kosut, PR #1094]
*) *Really* disable all mod_rewrite operations if the engine is off.
Some things (like RewriteMaps) were checked/performed even if they
weren't supposed to be. [Ken Coar, PR #991]
*) Implement a new timer scheme which eliminates the need to call alarm() all
the time. Instead a counter in the scoreboard for each child is used to
show when the child has made forward progress. The parent samples this
counter every scoreboard maintenance cycle, and issues SIGALRM if no
progress has been made in the timeout period. This reduces the static
request best-case syscall count to 22 from 29. This scheme is only
used by systems with memory-based scoreboards. [Dean Gaudet]
*) The proxy now properly handles CONNECT requests which are sent
to proxy servers when using ProxyRemote. [Marc Slemko, PR#1024]
*) A script called apachectl has been added to the support
directory. This script allows you to do things such as
"apachectl start" and "apachectl restart" from the command
line. [Marc Slemko]
*) Modules and core routines are now put into libraries, which
simplifies the link line tremendously (among other advantages).
[Paul Sutton]
*) Some of the MD5 names defined in Apache have been renamed to have
an `ap_' prefix to avoid conflicts with routines supplied by
external libraries. [Ken Coar]
*) Removal of mod_auth_msql.c from the distribution. There are many
other options for databases today. Rather than offer one option,
offer none at this time. mod_auth_msql and other SQL database
authentication modules can be found at the Apache Module Registry.
http://modules.apache.org/ It would be nice to offer a generic
mod_auth_sql option in the near future.
*) PORT: BeOS support added [Alexei Kosut]
*) Configure no longer accepts the -make option, since it creates
Makefile on the fly based on Makefile.tmpl and Configuration.
*) Apache now gracefully shuts down when it receives a SIGTERM, instead
of forcibly killing off all its processes and exiting without
cleaning up. [Alexei Kosut]
*) API: A new field in the request_rec, r->mtime, has been added to
avoid gratuitous parsing of date strings. It is intended to hold
the last-modified date of the resource (if applicable). An
update_mtime() routine has also been added to advance it if
appropriate. [Roy Fielding, Ken Coar]
*) If a htaccess file can not be read due to bad permissions, deny
access to the directory with a HTTP_FORBIDDEN. The previous
behavior was to ignore the htaccess file if it could not
be read. This change may make some setups with unreadable
htaccess files stop working. PR#817 [Marc Slemko]
*) Add aplog_error() providing a mechanism to define levels of
verbosity to the server error logging. This addition also provides
the ability to log errors using syslogd. Error logging is configurable
on a per-server basis using the LogLevel directive. Conversion
of log_*() in progress. [Randy Terbush]
*) Further enhance aplog_error() to not log filename, line number, and
errno information when it isn't applicable. [Ken Coar, Dean Gaudet]
*) WIN32: Canonicalise filenames under Win32. Short filenames are
converted to long ones. Backslashes are converted to forward
slashes. Case is converted to lower. Parts of URLs that do not
correspond to files are left completely alone. [Ben Laurie]
*) PORT: 2 new OSs added to the list of ports:
Encore's UMAX V: Arieh Markel <am...@encore.com>
Acorn RISCiX: Stephen Borrill <sb...@xemplar.co.uk>
*) Add the server version (SERVER_VERSION macro) to the "server
configured and running" entry in the error_log. Also build an
object file at link-time that contains the current time
(SERVER_BUILT global const char[]), and include that in the
message. [Ken Coar]
*) Set r->headers_out when sending responses from the proxy.
This fixes things such as the logging of headers sent from
the proxy. PR#659 [Marc Slemko]
*) support/httpd_monitor is no longer distributed because the
scoreboard should not be file based if at all possible. Use
mod_status to see current server snapshot.
*) (set_file_slot): New function, allowing auth directives to be
independent of the server root, so the server documents can be
moved to a different directory or machine more easily.
[David J. MacKenzie]
*) If no TransferLog is given explicitly, decline
to log. This supports coexistence with other logging modules,
such as the custom one that UUNET uses. [David J. MacKenzie]
*) Check for titles in server-parsed HTML files.
Ignore leading newlines and returns in titles. The old behavior
of replacing a newline after <title> with a space causes the
title to be misaligned in the listing. [David J. MacKenzie]
*) Change mod_cern_meta to be configurable on a per-directory basis.
[David J. MacKenzie]
*) Add 'Include' directive to allow inclusion of configuration
files within configuration files. [Randy Terbush]
*) Proxy errors on connect() are logged to the error_log (nothing
new); now they include the IP address and port that failed
(*that's* new). PR#352 [Ken Coar, Marc Slemko]
*) Various architectures now define USE_MMAP_FILES which causes
the server to use mmap() for static files. There are two
compile-time tunables MMAP_THRESHOLD (minimum number of bytes
required to use mmap(), default is 0), and MMAP_SEGMENT_SIZE (maximum
number of bytes written in one cycle from a single mmap()d object,
default 32768). [Dean Gaudet]
*) API: Added post_read_request API phase which is run right after reading
the request from a client, or right after an internal redirect. It is
useful for modules setting environment variables that depend only on
the headers/contents of the request. It does not run during subrequests
because subrequests inherit pretty much everything from the main
request. [Dean Gaudet]
*) Added mod_unique_id which is used to generate a unique identifier for
each hit, available in the environment variable UNIQUE_ID.
[Dean Gaudet]
*) init_modules is now called after the error logs have been opened. This
allows modules to emit information messages into the error logs.
[Dean Gaudet]
*) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
information for case where proxy module is not available. [Marc Slemko]
*) PORT: Apache has need for mutexes to serialize its children around
accept. In prior versions either fcntl file locking or flock file
locking were used. The method is chosen by the definition of
USE_xxx_SERIALIZED_ACCEPT in conf.h. xxx is FCNTL for fcntl(),
and FLOCK for flock(). New options have been added:
- SYSVSEM to use System V style semaphores
- PTHREAD to use POSIX threads (appears to work on Solaris only)
- USLOCK to use IRIX uslock
Based on timing various techniques, the following changes were made
to the defaults:
- Linux 2.x uses flock instead of fcntl
- Solaris 2.x uses pthreads
- IRIX uses SysV semaphores -- however multiprocessor IRIX boxes
work far faster if you -DUSE_USLOCK_SERIALIZED_ACCEPT
[Dean Gaudet, Pierre-Yves Kerembellec <Pi...@vtcom.fr>,
Martijn Koster <m....@pobox.com>]
*) PORT: The semantics of accept/select make it very desirable to use
mutexes to serialize accept when multiple Listens are in use. But
in the case where only a single socket is open it is sometimes
redundant to serialize accept(). Not all unixes do a good job with
potentially dozens of children blocked on accept() on the same
socket. It's now possible to define SAFE_UNSERIALIZED_ACCEPT and
the server will avoid serialization when listening on only one socket,
and use serialization when listening on multiple sockets.
[Dean Gaudet] PR#467
*) Configure changes: TestLib replaced by TestCompile, which has
some additional capability (such as doing a sanity check of
the compiler and flags selected); the version of Solaris is now
available via the #define value of SOLARIS2; IRIX n32bit libs
now supported and selectable by new Configuration Rule: IRIXN32;
We no longer default to -O2 optimization. [Jim Jagielski]
*) Updated Configure: Configuration now uses AddModule to specify
module source or binary file location, relative to src directory.
Modules can be dropped into modules/extra, or in their own
directory, and modules can come with a Makefile or Configure can
create one. Modules can add compiler or library information to
generated Makefiles. [Paul Sutton]
*) Source core re-organisation: distributed modules are now in
modules/standard. All other source code is in main. OS-specific
code is in os/{unix,emx,win32} directories. [Paul Sutton]
*) mod_browser has been removed, since it's replaced by mod_setenvif.
[Ken Coar]
*) Fix another long-standing bug in sub_req_lookup_file where it would
happily skip past access checks on subdirectories looked up with
relative paths. (It's used by mod_dir, mod_negotiation,
and mod_include.) [Dean Gaudet]
*) directory_walk optimization to reduce an O(N*M) loop to O(N+M) where
N is the number of <Directory> sections, and M is the number of
components in the filename of an object.
To achieve this optimization the following config changes were made:
- Wildcards (* and ?, not the regex forms) in <Directory>s,
<Files>s, and <Location>s now treat a slash as a special
character. For example "/home/*/public_html" previously would
match "/home/a/andrew/public_html", now it only matches things
like "/home/bob/public_html". This mimics /bin/sh behaviour.
- It's possible now to use [] wildcarding in <Directory>, <Files>
or <Location>.
- Regex <Directory>s are applied after all non-regex <Directory>s.
[Dean Gaudet]
*) Fix a bug introduced in 1.3a1 directory_walk regarding .htaccess files
and corrupted paths. [Dean Gaudet]
*) Enhanced and cleaned up the URL rewriting engine of mod_rewrite:
First the grouped parts of RewriteRule pattern matches (parenthesis!) can
be accessed now via backreferences $1..$9 in RewriteConds test-against
strings in addition to RewriteRules subst string. Second the grouped
parts of RewriteCond pattern matches (parenthesis!) can be accessed now
via backreferences %1..%9 both in following RewriteCond test-against
strings and RewriteRules subst string. This provides maximum flexibility
through the use of backreferences.
Additionally the rewriting engine was cleaned up by putting common
code to the new expand_backrefs_inbuffer() function.
[Ralf S. Engelschall]
*) When merging the main server's <Directory> and <Location> sections into
a vhost, put the main server's first and the vhost's second. Otherwise
the vhost can't override the main server. [Dean Gaudet] PR#717
*) The <Directory> code would merge and re-merge the same section after
a match was found, possibly causing problems with some modules.
[Dean Gaudet]
*) ip-based vhosts are stored and queried using a hashing function, which
has been shown to improve performance on servers with many ip-vhosts.
Some other changes had to be made to accommodate this:
- the * address for vhosts now behaves like _default_
- the matching process now is:
- match an ip-vhost directly via hash (possibly matches main
server)
- if that fails, just pretend it matched the main server
- if so far only the main server has been matched, perform
name-based lookups (ServerName, ServerAlias, ServerPath)
*only on name-based vhosts*
- if they fail, look for _default_ vhosts
[Dean Gaudet, Dave Hankins <dh...@sugarat.net>]
*) dbmmanage overhaul:
- merge dbmmanage and dbmmanage.new functionality, remove dbmmanage.new
- tie() to AnyDBM_File which will use one of DB_File, NDBM_File or
GDBM_File (-ldb, -lndbm, -lgdbm) (trying each in that order)
- provide better seed for rand
- prompt for password as per getpass(3) (turn off echo, read from
/dev/tty, etc.)
- use "newstyle" crypt based on $Config{osname} ($^O)
- will not add a user if already in database, use new `update' command
instead
- added `check' command to check a users' password
- added `import' command to convert existing password text-files or
dbm files exported with `view'
- more descriptive usage, general cleanup, 'use strict' clean, etc.

*) Added psocket() which is a pool form of socket(), various places within
the proxy weren't properly blocking alarms while registering the cleanup
for its sockets. bclose() now uses pclose() and pclosesocket(). There
was a bug where the client socket was being close()d twice due a still
registered cleanup. [Dean Gaudet]
*) A few cleanups were made to reduce time(), getpid(), and signal() calls.
[Dean Gaudet]
*) PORT: AIX >= 4.2 requires -lm due to libc changes.
[Jason Venner <ja...@idiom.com>] PR#667
*) Enable ``=""'' for RewriteCond directives to match against
the empty string. This is the preferred way instead of ``^$''.
[Ralf S. Engelschall]
*) Fixed an infinite loop in mod_imap for references above the server root
[Dean Gaudet] PR#748
*) mod_proxy now has a ReceiveBufferSize directive, similar to
SendBufferSize, so that the TCP window can be set appropriately
for LFNs. [Phillip A. Prindeville]
*) mod_browser has been replaced by the more general mod_setenvif
(courtesy of Paul Sutton). BrowserMatch* directives are still
available, but are now joined by SetEnvIf*, UnSetEnvIf*, and
UnSetEnvIfZero directives. [Ken Coar]
*) "HostnameLookups double" forces double-reverse DNS to succeed in
order for remote_host to be set (for logging, or for the env var
REMOTE_HOST). The old define MAXIMUM_DNS has been deprecated.
[Dean Gaudet]
*) mod_access overhaul:
- Now understands network/netmask syntax (i.e. 10.1.0.0/255.255.0.0)
and cidr syntax (i.e. 10.1.0.0/16). PR#762
- Critical path was sped up by pre-computing a few things at config
time.
- The undocumented syntax "allow user-agents" was removed,
the replacement is "allow from env=foobar" combined with mod_browser.
- When used with hostnames it now forces a double-reverse lookup
no matter what the directory settings are. This double-reverse
doesn't affect any of the other routines that use the remote
hostname. In particular it's still passed to CGIs and the log
without the double-reverse check. Related PR#860.
[Dean Gaudet]
*) When a large bwrite() occurs (larger than the internal buffer size),
while there is already something in the buffer, apache will combine
the large write and the buffer into a single writev(). (This is
in anticipation of using mmap() for reading files.)
[Dean Gaudet]
*) In obscure cases where a partial socket write occurred while chunking,
Apache would omit the chunk header/footer on the next block. Cleaned
up other bugs/inconsistencies in error conditions in buff.c. Fixed
a bug where a long pause in DNS lookups could cause the last packet
of a response to be unduly delayed. [Roy Fielding, Dean Gaudet]
*) API: Added child_exit function to module structure. This is called
once per "heavy-weight process" just before a server child exit()'s
e.g. when max_requests_per_child is reached, etc.
[Doug MacEachern, Dean Gaudet]
*) mod_include cleanup showed that handle_else was being used to handle
endif. It didn't cause problems, but it was cleaned up too.
[Howard Fear]
*) mod_cern_meta would attempt to find meta files for the directory itself
in some cases, but not in others. It now avoids it in all cases.
[Dean Gaudet]
*) mod_mime_magic would core dump if there was a decompression error.
[Martin Kraemer <Ma...@mch.sni.de>] PR#904
*) PORT: some variants of DGUX require -lsocket -lnsl
[Alexander L Jones <al...@systems-options.co.uk>] PR#732
*) mod_autoindex now allows sorting of FancyIndexed directory listings
by the various fields (name, size, et cetera), either in ascending
or descending order. Just click on the column header. [Ken Coar]
*) PORT: Various tweaks to eliminate pointer-int casting warnings on 64-bit
CPUs like the Alpha. Apache still stores ints in pointers, but that's
the relatively safe direction. [Dean Gaudet] PR#344
*) PORT: QNX mmap() support for faster/more reliable scoreboard handling.
[Igor N Kovalenko <in...@mail.wplus.net>] PR#683
*) child_main avoids an unneeded call to select() when there is only one
listening socket. [Dean Gaudet]
*) In the event that the server is starved for idle servers it will
spawn 1, then 2, then 4, ..., then 32 servers each second,
doubling each second. It'll also give a warning in the errorlog
since the most common reason for this is a poor StartServers
setting. The define MAX_SPAWN_RATE can be used to raise/lower
the maximum. [Dean Gaudet]
*) Apache now provides an effectively unbuffered connection for
CGI scripts. This means that data will be sent to the client
as soon as the CGI pauses or stops output; previously, Apache would
buffer the output up to a fixed buffer size before sending, which
could result in the user viewing an empty page until the CGI finished
or output a complete buffer. It is no longer necessary to use an
"nph-" CGI to get unbuffered output. Given that most CGIs are written
in a language that by default does buffering (e.g. perl) this
shouldn't have a detrimental effect on performance.
"nph-" CGIs, which formerly provided a direct socket to the client
without any server post-processing, were not fully compatible with
HTTP/1.1 or SSL support. As such they would have had to implement
the transport details, such as encryption or chunking, in order
to work properly in certain situations. Now, the only difference
between nph and non-nph scripts is "non-parsed headers".
[Dean Gaudet, Sameer Parekh, Roy Fielding]
*) If a BUFF is switched from buffered to unbuffered reading the first
bread() will return whatever remained in the buffer prior to the
switch. [Dean Gaudet]
Changes with Apache 1.3a1
*) Added another Configure helper script: TestLib. It determines
if a specified library exists. [Jim Jagielski]
*) PORT: Allow for use of n32bit libraries under IRIX 6.x
[derived from patch from Jeff Hayes <jh...@aw.sgi.com>]
(PR#721)
*) PORT: Some architectures use size_t for various lengths in network
functions such as accept(), and getsockname(). The definition
NET_SIZE_T is used to control this. [Dean Gaudet]
*) PORT: Linux: Attempt to detect glibc based systems and include crypt.h
and -lcrypt. Test for various db libraries (dbm, ndbm, db) when
mod_auth_dbm or mod_auth_db are included. [Dean Gaudet]
*) PORT: QNX doesn't have initgroups() which support/suexec.c uses.
[Igor N Kovalenko <in...@mail.wplus.net>]
*) "force-response-1.0" now only applies to requests which are HTTP/1.0 to
begin with. "nokeepalive" now works for HTTP/1.1 clients. Added
"downgrade-1.0" which causes Apache to pretend it received a 1.0.
[Dean Gaudet] related PR#875
*) API: Correct child_init() slot declaration from int to void, to
match the init() declaration. Update mod_example to use the new
hook. [Ken Coar]
*) added transport handle slot (t_handle) to the BUFF structure
[Doug MacEachern]
*) get_client_block() returns wrong length if policy is
REQUEST_CHUNKED_DECHUNK.
[Kenichi Hori <ke...@d2.bs1.fc.nec.co.jp>] PR#815
*) Support the image map format of FrontPage. For example:
rect /url.hrm 10 20 30 40
["Chris O'Byrne" <ob...@iol.ie>] PR#807
*) PORT: -lresolv and -lsocks were in the wrong order for Solaris.
["Darren O'Shaughnessy" <da...@aaii.oz.au>] PR#846
*) AddModuleInfo directive for mod_info which allows you to annotate
the output of mod_info. ["Lou D. Langholtz" <ld...@usi.utah.edu>]
*) Added NoProxy directive to avoid using ProxyRemote for selected
addresses. Added ProxyDomain directive to cause unqualified
names to be qualified by redirection.
[Martin Kraemer <Ma...@mch.sni.de>]
*) Support Proxy Authentication, and don't pass the Proxy-Authorize
header to the remote host in the proxy. [Sameer Parekh and
Wallace]
*) Upgraded mod_rewrite from 3.0.6+ to latest officially available version
3.0.9. This upgrade includes: fixed deadlooping on rewriting to same
URLs, fixed rewritelog(), fixed forced response code handling on
redirects from within .htaccess files, disabled pipe locking under
braindead SunOS 4.1.x, allow env variables to be set even on rules with
no substitution, bugfixed situations where HostnameLookups is off, made
mod_rewrite more thread-safe for NT port and fixed problem when creating
an empty query string via "xxx?".
This update also removes the copyright of Ralf S. Engelschall,
i.e. now mod_rewrite no longer has a shared copyright. Instead is is
exclusively copyrighted by the Apache Group now. This happened because
the author now has gifted mod_rewrite exclusively to the Apache Group and
no longer maintains an external version.
[Ralf S. Engelschall]
*) API: Added child_init function to module structure. This is called
once per "heavy-weight process" before any requests are handled.
See http_config.h for more details. [Dean Gaudet]
*) Anonymous_LogEmail was logging on each subrequest.
[Dean Gaudet] PR#421, 868
*) API: Added is_initial_req() which tests if the request being
processed is the initial request, or a subrequest.
[Doug MacEachern]
*) Extended SSI (mod_include) now handles additional relops for
string comparisons (<, >, <=, and >=). [Bruno Wolff III] PR#41
*) Configure fixed to correctly propagate user-selected options and
settings (such as CC and OPTIM) to Makefiles other than
src/Makefile (notably support/Makefile). [Ken Coar] PR#666, #834
*) IndexOptions SuppressHTMLPreamble now causes the actual HTML of
directory indices to start with the contents of the HeaderName file
if there is one. If there isn't one, the behaviour is unchanged.
[Ken Coar, Roy Fielding, Andrey A. Chernov]
*) WIN32: Modules can now be dynamically loaded DLLs using the
LoadModule/LoadFile directives. Note that module DLLs must be
compiled with the multithreaded DLL version of the runtime library.
[Alexei Kosut and Ben Laurie]
*) Automatic indexing removed from mod_dir and placed into mod_autoindex.
This allows the admin to completely remove automatic indexing
from the server, while still supporting the basic functions of
trailing-slash redirects and DirectoryIndex files. Note that if
you're carrying over an old Configuration file and you use directory
indexing then you'll want to add:
Module autoindex_module mod_autoindex.o
before mod_dir in your Configuration. [Dean Gaudet]
*) popendir/pclosedir created to properly protect directory scanning.
[Dean Gaudet] PR#525
*) AliasMatch, ScriptAliasMatch and RedirectMatch directives added,
giving regex support to mod_alias. <DirectoryMatch>, <LocationMatch>
and <FilesMatch> sections added to succeed <DirectoryMatch ~>, etc...
[Alexei Kosut]
*) The AccessFileName directive can now take more than one filename.
["Lou D. Langholtz" <ld...@usi.utah.edu>]
*) The new mod_mime_magic can be used to "magically" determine the type
of a file if the extension is unknown. Based on the unix file(1)
command. [Ian Kluft <ik...@cisco.com>]
*) We now determine and display the time spent processing a
request if desired. [Jim Jagielski]
*) mod_status: PID field of "dead" child slots no longer displays
main httpd process's PID. [Jim Jagielski]
*) Makefile.nt added - to build all the bits from the command line:
nmake -f Makefile.nt
Doesn't yet work properly. [Ben Laurie]
*) Default text of 404 error is now "Not Found" rather than the
potentially misleading "File Not Found". [Ken Coar]
*) CONFIG: "HostnameLookups" now defaults to off because it is far better
for the net if we require people that actually need this data to
enable it. [Linus Torvalds]
*) directory_walk() is an expensive function, keep a little more state to
avoid needless string counting. Add two new functions make_dirstr_parent
and make_dirstr_prefix which replace all existing uses of make_dirstr.
The new functions are a little less general than make_dirstr, but
work more efficiently (less memory, less string counting).
[Dean Gaudet]
*) EXTRA_LFLAGS was changed to EXTRA_LDFLAGS (and LFLAGS was changed
to LDFLAGS) to avoid complications with lex rules in make files.
[Dean Gaudet] PR#372
*) run_method optimized to avoid needless scanning over NULLs in the
module list. [Dean Gaudet]
*) Revamp of (unix) scoreboard management code such that it avoids
unnecessary traversals of the scoreboard on each hit. This is
particularly important for high volume sites with a large
HARD_SERVER_LIMIT. Some of the previous operations were O(n^2),
and are now O(n). See also SCOREBOARD_MAINTENANCE_INTERVAL in
httpd.h. [Dean Gaudet]
*) In configurations using multiple Listen statements it was possible for
busy sockets to starve other sockets of service. [Dean Gaudet]
*) Added hook so standalone_main can be replaced at compile time
(define STANDALONE_MAIN)
[Doug MacEachern]
*) Lowest-level read/write functions in buff.c will be replaced with
the SFIO library calls sfread/sfwrite if B_SFIO is defined at
compile time. The default sfio discipline will behave as apache
would without sfio compiled in.
[Doug MacEachern]
*) Enhance UserDir directive (mod_userdir) to accept a list of
usernames for the 'disable' keyword, and add 'enable user...' to
selectively *en*able userdirs if they're globally disabled.
[Ken Coar]
*) If NETSCAPE_DBM_COMPAT is defined in EXTRA_CFLAGS then Apache
will work with Netscape dbm files. (dbmmanage will probably not
work however.) [Alexander Spohr <as...@netmatic.com>] PR#444
*) Add a ListenBacklog directive to control the backlog parameter
passed to listen(). Also change the default to 511 from 512.
[Marc Slemko]
*) API: A new handler response DONE which informs apache that the
request has been handled and it can finish off quickly, similar to
how it handles errors. [Rob Hartill]
*) Turn off chunked encoding after sending terminating chunk/footer
so that we can't do it twice by accident. [Roy Fielding]
*) mod_expire also issues Cache-Control: max-age headers.
[Rob Hartill]
*) API: Added kill_only_once option for free_proc_chain so that it won't
aggressively try to kill off specific children. For fastcgi.
[Stanley Gambarin <ga...@OpenMarket.com>]
*) mod_auth deals with extra ':' delimited fields. [Marc Slemko]
*) Added IconHeight and IconWidth to mod_dir's IndexOptions directive.
When used together, these cause mod_dir to emit HEIGHT and WIDTH
attributes in the FancyIndexing IMG tags. [Ken Coar]
*) PORT: Sequent and SONY NEWS-OS support added. [Jim Jagielski]
*) PORT: Added Windows NT support

The message was *really* long in my opinion, 50K per person, so with 9502
recipients we just pushed out almost 475 megabytes due to that message
along. That did somewhat add to transmission time.
