*) Some symbol renaming:
ap_spawn_child_err became ap_spawn_child
ap_spawn_child_err_buff became ap_bspawn_child
spawn_child was obsoleted and moved to compat.h
[Brian Behlendorf]
*) Upgrade the child spawning code in mod_rewrite for the RewriteMap
programs: ap_spawn_child_err() is used and the Win32 case now uses
CreateProcess() instead of a low-level execl() (which caused problems in
the past under Win32).
[Ralf S. Engelschall]
*) A few cosmetics and trivial enhancements to APXS to make the
generated Makefile more user friendly. [Ralf S. Engelschall]
*) Proxy Fix: The proxy special failure routine ap_proxyerror()
was updated to use the normal apache error processing, thereby allowing
proxy errors to be treated by ErrorDocument's as well. For this
purpose, a new module-to-core communication variable "error-notes"
was introduced; the proxy (and possibly other modules) communicates
its error text using this variable. Its content is copied to a new
cgi-env-var REDIRECT_ERROR_NOTES for use by ErrorDocuments.
The old proxy special error routine ap_proxy_log_uerror()
was replaced by regular ap_log_error() calls, many messages were made
more informative.
[Martin Kraemer] PR#494, 1259
*) SECURITY: A possible buffer overflow in the ftp proxy was fixed.
[Martin Kraemer]
*) Transform the configure message "You need root privileges for suEXEC"
from a fatal error into a (more friendly) warning because the building
("make") of Apache we can allow, of course. Root privileges are needed
only for the installation step ("make install"). So make sure the
user is aware of this fact but let him proceed as long as he can.
[Ralf S. Engelschall] PR#2288
*) Renamed three more functions to common ap_ prefix which we missed at the
Big Symbol Renaming because they're #defines and not real C functions:
is_default_port(), default_port(), http_method().
[Ralf S. Engelschall]
*) A zero-length name after a $ in an SSI document should cause
just the $ to be in the expansion. This was broken during the
security fixes in 1.2.5. [Dean Gaudet] PR#1921, 2249

used under AIX) because of recent changes to function names.
[Ralf S. Engelschall]
Changes with Apache 1.3b7
*) Make sure a MIME-type can be forced via a RewriteRule even when no
substitution takes place, for instance via the following rule:
``RewriteRule ^myscript$ - [T=application/x-httpd-cgi]'' This was often
requested by users in the past to force a single script without a .cgi
extension and outside any cgi-bin dirs to be executed as a CGI program.
[Ralf S. Engelschall] PR#2254
*) A fix for protocol issues surrounding 400, 408, and
414 responses. [Ed Korthof]
*) Ignore MaxRequestsPerChild on WIN32. [Brian Behlendorf]
*) Fix discrepancy in proxy_ftp.c which was causing failures when
trying to connect to certain ftpd's, such as anonftpd.
*) Make mod_rewrite use ap_open_piped_log() for RewriteLog directive's
logfile instead of fiddling around itself with child spawning stuff.
[Ralf S. Engelschall]
*) Made RefererIgnore case-insensitive.
*) Mod_log_agent, mod_log_referer now use ap_open_piped_log for piped logs.
[Brian Behlendorf]
*) Replace use of spawn_child with ap_spawn_child_err_buff, to make everything
"safe" under Win32. In: mod_include.c, mod_mime_magic.c
[Brian Behlendorf]
*) Improve RFC1413 support. [Bob Beck <beck bofh.ucs.ualberta.ca>]
*) Fix support script `dbmmanage': It was unable to handle some sort
of passwords, especially passwords with "0" chars.
[Ralf S. Engelschall] PR#2242
*) WIN32: Clicking on "Last Modified" in a fancy index caused a crash. Fixed.
[Ben Laurie] PR#2238
*) WIN32: CGIs could cause a hang (because of a deadlock in the standard C
library), so CGI handling has been changed to use Win32 native handles
instead of C file descriptors.
[Ben Laurie and Bill Stoddard <wgstodda us.ibm.com>] PR#1129, 1607
*) The proxy cache would store an incorrect content-length in the cached
file copy after a cache update. That resulted in repeated fetching
of the original copy instead of using the cached copy.
*) The Makefiles assumed that DSO files are build via $(LD). This
is broken for two reasons: First we never defined at least LD=ld
somewhere to make sure this works (it was silently assumed that most Make
provide a built-in LD definition - ARGL!) and second using the generic LD
variable is not the truth. Instead a special variable named LD_SHLIB is
reasonable because although "ld" is usually the default, the command for
building DSO files can be "libtool" or even "cc" on some systems.
[Ralf S. Engelschall]
*) Replace the AddVersionPlatform directive with ServerTokens which
provides for more control over the format of the Server:
header line. SERVER_SUBVERSION is no longer supported;
all module should use the ap_add_version_component()
API function instead. [Jim Jagielski]
*) Support for the NCR MP/RAS 3.0

*) The LDFLAGS_SHLIB_EXPORT variable of src/Configuration[.tmpl] was
not retrieved in src/Configure and thus was not useable.
[Ralf S. Engelschall]
*) Various Makefile consistency cleanups:
- make OSDIR also automatically be relative to src/ like INCDIR
- SUBDIRS is now generated in src/Makefile only and not in
Makefile.config because it is a local define for this location.
- remove BROKEN_BPRINTF_FLAGS because is it no longer used inside
any Makefile but make sure that at least the "-K inline" is kept in
CFLAGS for SCO 5.
- update the "depend" targets in Makefile.tmpl files to use $(OSDIR), too.
- updated the dependencies theirself
- removed not existing SHLIB variable from "clean" targets
- replaced SHLIB_OBJS/SHLIBS_OBJ consistently with OBJS_PIC because OBJS
already exists and OBJS_PIC are also just plain objects and have not
directly to do with "shared" things. The only difference is that they
contain PIC. So OBJS_PIC is the more canonical name.
- Updated the Makefile-dependency lines for OBJS_PIC
- Removed the Makefile-dependency line in Configure to avoid double
definitions
- replaced ugly xx-so.o/xx.so-o hack with a clean and consistent usage
of xxx.lo as GNU libtool does with its PIC objects
- reduce local complexity in modules Makefile.tmpl by moving the last
existing target "depend" to the generation section in Configure, too.
- removed the historical $(SPACER) which was used in the past together
with BROKEN_BPRINTF_FLAGS to avoid zig-zags in the build process. This
is no longer needed.
- force the build and run of the gen_xxx programs under main/ as the
first step before building the objects because it looks cleaner
[Ralf S. Engelschall]

*) When opening "configuration" files (like httpd.conf, htaccess
and htpasswd), Apache will not allow them to be non-/dev/null
device files. This closes a DoS hole. At the same time,
we use ap_pfopen to open these files to handle timeouts.
[Jim Jagielski, Martin Kraemer]
*) Apache will now log the reason its httpd children exit if they exit
due to an unexpected signal. (It requires a new porting define,
SYS_SIGLIST, which if defined should point to a list of text
descriptions of the signals available. See PORTING.) [Dean Gaudet]
*) WIN32: chdir() doesn't make sense in a multithreaded environment
like WIN32. Before, Win32 CGI's could have had sporadic failures
if a chdir call from one thread was made between another chdir call
and a spawn in another thread. So, for now don't chdir for CGI scripts
in WIN32. The current CGI "spec" is unclear as to whether it's
necessary. Long-term fix is to either serialize the chdir/spawn combo
or use WIN32 native calls to spawn a process. This temp fix was
necessary to remove this as a showstopper for 1.3's release.
[Brian Behlendorf]
*) Cleanup the suEXEC support in APACI and make it more safe:
1. Add big fat hint in INSTALL about risks and to read the
htdocs/manual/suexec.html document before using the suexec-related
configure options.
2. Make sure the user has at least provided one --suexec-xxxx option
(specifies suEXEC parameters) in addition to --enable-suexec option.
If only --enable-suexec is given APACI stops with a hint to INSTALL
and htdocs/manual/suexec.html documents.
3. Provide two additional --suexec-xxxx options to make the suEXEC
configuration complete (especially for package maintainers who else
had to patch the source tree) by providing ways to configure minimal
UID/GID and safe PATH, too.
[Ralf S. Engelschall]
*) Cleanup of the `configure --shadow' process:
- make sure the configure script creates its temporary files in the
shadow tree to avoid conflicts with parallel configure runs
- removed unnecessary option "-r" from "rm" call for Makefiles
- make sure the configure scripts creates the shadow-wrapper Makefile
only when no shadow trees already exists
- make sure "make distclean" removes the shadow-wrapper Makefile but only
when no more shadow trees exists
- overhauled mkshadow.sh script: now its more IFS-safe and approx. twice
as fast (in the past it needed 70sec, now it runs just 38sec)
- make sure CVS does not complain about the created files
Makefille.<gnutriple> and directories src.<gnutriple>
[Ralf S. Engelschall]
*) Added the ap_add_version_component() API routine and the
AddVersionPlatform core directive. The first allows modules to
declare themselves in the Server response header field value,
augmenting the SERVER_SUBVERSION define in the Configuration file
with run-time settings (more useful in a loadable-module environment).
AddVersionPlatform inserts a comment such as "(UNIX)" or "(Win32)"
into the server version string. [Ken Coar] PR#2056
*) Minor stability tweaks to avoid core dumps in ap_snprintf.
[Martin Kraemer]
*) Emit the "Accept-Range" header for the default handler.
[Brian Behlendorf] PR#1464
*) Add a note to httpd.conf-dist that apache will on some systems fail
to start when the Group # is set to a negative or large positive value.
[Martin Kraemer]
*) Make sure the module execution order is correct even when some modules
are loaded under runtime (`LoadModule') via the DSO mechanism:
1. The list of loaded modules is now a dynamically allocated one
and not the original statically list from modules.c
2. The loaded modules are now correctly setup by LoadModule for
later use by the AddModule command.
3. When the DSO mechanism for modules is used APACI's `install'
target now enables all created `LoadModule' lines per default because
this is both already expected by the user _and_ needed to avoid
confusion with the next point and reduces the Makefile.tmpl complexity
4. When the DSO mechanism for modules is used, APACI's `install'
target now additionally makes sure the module list is reconstructed
via a complete `ClearModuleList+AddModule...' entry.
5. The support tool `apxs' now also makes sure an AddModule command
is added in addition to the LoadModule command.
6. The modules.c generation was extended to now contain two
comments to make sure no one is confused by the confusing terminology
of loading/linking (we use load=link+load & link=activate instead of
the obvious load=activate & link=link :-( )
This way now there is no longer a difference under execution time between
statically and dynamically linked modules.
[Ralf S. Engelschall]
*) Fix the generated mod_xxx.c from "apxs -g -f xxx" after the
Big Symbol Renaming. [Ralf S. Engelschall]
*) Add a comment to mod_example.c showing the format of a FLAG command
handler. [Ken Coar]
*) Standardized the time format in mod_status to match that of other
places in the code (e.g. DATE_GMT). PR#1551
*) Fix handling of %Z in timefmt strings for those platforms with no time
zone information in their tm struct. [Paul Eggert <eggert twinsun.com>]

PR#754
*) Makes mod_rewrite, mod_log_config, mod_status and the ServerSignature
feature compatible with 'UseCanonicalName off' by changing
r->server->server_hostname to ap_get_server_name(). And I changed some
functions which use r->server->port to use ap_get_server_port() instead,
because if there's no Port directive in the config r->server->port is 0.

*) get/set_module_config are trivial enough to be better off inline. Worth
1.5% performance boost. [Dean Gaudet]

when ensuring 'x' is at least 30-chars big. [Jim Jagielski,
Brian Behlendorf]
*) [BS2000 security] BS2000 needs an extra authentication to initialize
the task environment to the unprivileged User id. Otherwise CGI scripts
would have a way to gain super user access. [Martin Kraemer]
*) Fix debug log messages for BS2000/OSD: instead of logging the whole
absolute path, only log base name of logging source as is done
in unix. [Martin Kraemer]
*) Ronald Tschalaer's Accept-Encoding patch - preserve the "x-" in
the encoding type from the Accept-Encoding header (if it's there)
and use it in the response, as that's probably what it'll be expecting.
*) Fix to mod_alias: translate_alias_redir is dealing with
a URI, not a filename, so the check for drive letters for win32
and emx is not necessary. [Dean Gaudet]
*) WIN32: Allow .cmd as an executable extension.
*) Make Apache header files, and some variables, C++ friendly.

*) PORT: Various porting changes to support AIX 3.2, 4.1.5, 4.2 and 4.3.
Additionally the checks for finding the vendor DSO library were moved
from mod_so.c to Configure because first it needs $PLAT etc. and second
mod_so already uses an abstraction layer and does not fiddle with the
vendor functions itself.
[Jens-Uwe Mager, Ralf S. Engelschall]
*) PORT: Some optimization defines for NetBSD
*) PORT: Dynamic Shared Object (DSO) support for NetBSD.
[Jaromir Dolecek <dolecek ics.muni.cz>, Ralf S. Engelschall] PR#2158
*) Add Dynamic Shared Object (DSO) support for AIX (at least 4.2 but older
AIX variants should work fine, too. Even AIX 3.x should work). This is
accomplished by using the free DSO emulation code from Jens-Uwe Mager
which we put into a os/unix/os-dso-aix.c file.
[Ralf S. Engelschall]
*) PORT: Fix compiler warnings under AIX >= 4.2 where the manual pages imply
that we should use NET_SIZE_T == int but the include files force size_t.
[Ralf S. Engelschall]
*) Fix two bugs in select() handling in http_main.c.
[Roy Fielding]
*) Suppress "error(0)" messages for ap_log_error() when the APLOG_NOERRNO
is unset (as it is in situations like timeouts) where it is unclear
whether errno is set or not. [Martin Kraemer]
*) Just having APACI's localstatedir is too general and not enough for most
of the systems. 1.3b6 again required manual APACI patches by package
maintainers from Red Hat and FreeBSD because for their filesystem layout a
little bit more flexibility in configuring the paths is needed. Hence we
provide three additional configure options (--runtimedir, --logfiledir,
--proxycachedir) which now can be used for more granular adjustments if
--localstatedir is not enough to fit the particular needs. As a nice
side-effect this reduces some subdir fiddling in configure+Makefile.tmpl.
[Ralf S. Engelschall]
*) Make the install root for "make install" in APACI's Makefile overrideable
by package authors. This way we are even more friendly to package
maintainers (especially Debian and Red Hat) who build for the real prefix

*) If you start apache with the -S command line option it will dump
out the parsed vhost settings. This is useful for folks trying
to figure out what is wrong with their vhost configuration.
(Other dumps may be added in the future.) [Dean Gaudet]
*) Add %pA, %pI, and %pp codes to ap_vformatter (and hence ap_bprintf,
ap_snprintf, and ap_psprintf). See include/ap.h for docs.
[Dean Gaudet]
*) Because /usr/local/apache is the default prefix the ``configure
--compat'' option no longer has to set prefix, again. This way the
--compat option honors a leading --prefix option. [Lars Eilebrecht]
*) PORT: Cast the first argument of dlopen() in ap_os_dso_load()
to `char *' under OSF1 and FreeBSD 2.x where it is defined this way
to avoid "discard const" warnings. [Ralf S. Engelschall]
*) If a specific handler is set for a file yet the request still
ends up being handled by the default handler, log an error
message before handling it. This catches things such as trying
to use SSIs without mod_include enabled. [Marc Slemko]
*) Fix error logging for the startup case where ap_log_error() still uses
stderr as the target. Now the default log level is honored here, too.
[Ralf S. Engelschall]
*) PORT: Make sure some AWK's don't fail in src/Configure with "string too
long" errors when generating the MODULES entry for src/Makefile
[Ben Hyde, Ralf S. Engelschall]
*) Make sure src/Configure doesn't complain about the old directory
/usr/local/etc/httpd/ when APACI is used. [Lars Eilebrecht]
Changes with Apache 1.3b6
*) PORT: Clean up warnings on Ultrix and HPUX. [Ben Hyde]
*) Adding DSO support for the HP/UX platform by emulating the dlopen-style
interface via the similar but proprietary HP/UX shl_xxx-style system
calls. [Ralf S. Engelschall]
*) PORT: Updated UnixWare 2.0.x and 2.1.x entries for DSO support and made
APACI Makefile.tmpl "install" target more robust for sensible UnixWare
Make. [Ralf S. Engelschall]
*) ++++ THE BIG SYMBOL RENAMING ++++
To avoid symbol clashes with third-party code compiled into the server,
we globally applied the prefix "ap_" to the following classes of
functions:
- Apache provided general functions (e.g., ap_cpystrn)
- Public API functions (e.g., palloc, bgets)
- Private functions which we can't make static (because of
cross-object usage) but should be (e.g., new_connection)
For backward source compatibility a new header file named compat.h was
created which provides defines for the old symbol names and can be used
by third-party module authors.
[The Apache Group]
*) Added dynamic shared object (DSO) support for SVR4-derivates: The
problem under SVR4 is that there is no command flag to force the linker
to export the global symbols of the httpd executable therewith they are
available to the DSO's. Instead of problematic hacks like creating a
dummy.so file (containing dummy references to all global symbols) the
httpd binary is linked against, we use a clean trick stolen from Perl 5:
Placing the Apache core code itself into a DSO library named libhttpd.so.
This way the global symbols _HAVE_ to be exported and thus are available
to any manually loaded DSO's under runtime. To reduce the impact to the
user to null we go even further and create a stub httpd executable which
automatically keeps track of the DSO library loading itself and thus
hides the complete mechanism from the user. Although the generation of
this DSO library is automatically triggered for platforms which
essentially need it (mostly all SVR4-derivates) it can be also enabled
manually via the Rule SHARED_CORE. This can be interesting in the future
where we perhaps exploit this libhttpd.so mechanism for providing nifty
features like graceful upgrades, or whatever.
[Ralf S. Engelschall, Martin Kraemer]
*) Build the libraries before building the rest of the tools. [Ben Hyde]
*) Add "distclean" target to src/-Makefiles to provide "make distclean" also
inside the src subtree (i.e. for non-APACI users). Following GNU Makefile
conventions while "clean" removes only stuff created by "all" targets,
"distclean" additionally removes the stuff from the configuration
process. This way "make distclean" (hence the name) provides a fresh
source tree as it was for distribution.
[Ralf S. Engelschall]
*) Allow top-level (APACI) Makefile to break on build errors
the same way the src/ subtree Makefiles breaks on them by replacing the
initial APACI sed-subdir-display-kludge with a more clean
variable-passing-solution: variable SDP can optionally hold the subdir
prefix which is consistently used for displaying the subdir movement.
This way even the top-level Makefile can stop correctly on errors as the
user expects. [Ralf S. Engelschall]
*) Fixed ordering of argument checks for RewriteBase directive.

*) Change Win32 IS_MODULE to SHARED_MODULE to match Unix' method of
indicating that a module is being compiled for dynamic loading. Also
remove #define IS_MODULE from modules and add SHARED_MODULE define
to the mak/dsp files. [Alexei Kosut]
*) Reduce logging level of "normal" warning messages to APLOG_INFO,
since we are now logging APLOG_WARNING by default. [Roy Fielding]
*) PORT: OS/2 tweak to deal with multiple .exe targets. [Brian Havard]
*) Add documentation file and src/Configuration.tmpl entry for the
experimental mod_mmap_static module. Because although it is and marked as
an experimental one it is distributed and thus should be documented and
prepared for configuration the same way as all others modules.
[Ralf S. Engelschall]
*) Add query (-q) option to apxs support tool to be able to manually query
specific settings from apxs. This is needed for instance when you
manually want to access Apache's header files and you need to assemble
the -I option. Now you can do -I`apxs -q INCLUDEDIR`.
[Ralf S. Engelschall]
*) Now src/Configure uses a fallback strategy for the shared object support
on platforms where no explicit information is available: If a Perl
installation exists we ask it about its shared object support and if it's
the dlopen-style one we shamelessly guess the compiler and linker flags
for creating shared objects from Perls knowledge. Of course, the user is
warning about what we are doing and informed that he should send us
the guessed flags when they work. [Ralf S. Engelschall]
*) Provide APACI --without-support option to be able to disable the build
and installation of the support tools from the src/support/ area.
Although its useful to have these installed per default we should provide
a way to compile and install without them for backward-compatibility.
[Ralf S. Engelschall]
*) Add of the new APache eXtenSion (apxs) support tool for building and
installing modules into an _already installed_ Apache package through the
dynamic shared object (DSO) mechanism [mod_so.c]. The trick here is that
this approach actually doesn't need the Apache source tree. The
(APACI-installed) server package is enough, because this now includes the
Apache C header files (PREFIX/include) and the new APXS tool
(SBINDIR/apxs). The intend is to provide a handy tool for third-party
module authors to build their Apache modules _OUTSIDE_ the Apache source
tree while avoiding them to fiddle around with the totally platform
dependend way of compiling DSO files. The tool supports all ranges of
modules, from trivial ones (single mod_foo.c) to complex ones (like PHP3
which has a mod_php3.c plus a pre-built libmodphp3-so.a) and even can
on-the-fly generate a minimalistic Makefile and sample module for the
first step to provide both a quick success event and to demonstrate the
APXS mechanism to module authors. [Ralf S. Engelschall]
*) Fix core dumps in use of CONNECT in proxy.

*) Modify the log directives in httpd.conf-dist files to use CustomLog
so that users have examples of how CustomLog can be used.
[Lars Eilebrecht]
*) Add the new Apache Autoconf-style Interface (APACI) for the top-level of
the Apache distribution tree. Until Apache 1.3 there was no real
out-of-the-box batch-capable build and installation procedure for the
complete Apache package. This is now provided by a top-level "configure"
script and a corresponding top-level "Makefile.tmpl" file. The goal is
to provide a GNU Autoconf-style frontend which is capable to both drive
the old src/Configure stuff in batch and additionally installs the
package with a GNU-conforming directory layout. Any options from the old
configuration scheme are available plus a lot of new options for flexibly
customizing Apache. [Ralf S. Engelschall]
*) The floating point ap_snprintf code wasn't threadsafe.
Had to remove the HAVE_CVT macro in order to do threadsafe
calling of the ?cvt() floating point routines. [Dean Gaudet]
*) PORT: Add the SCO_SV port. [Jim Jagielski] PR#1962
*) PORT: IRIX needs the -n32 flag iff using the 'cc' compiler
[Jim Jagielski] PR#1901
*) BUG: Configure was using TCC and CC inconsistently. Make sure
Configure knows which CC we are using. [Jim Jagielski]
*) "Options +Includes" wasn't correctly merged if "+IncludesNoExec"
was defined in a parent directory. [Lars Eilebrecht]
*) API: ap_snprintf() code mutated into ap_vformatter(), which is
a generic printf-style routine that can call arbitrary output
routines. Use this to replace http_bprintf.c. Add new routines
psprintf(), pvsprintf() which allocate the exact amount of memory
required for a string from a pool. Use psprintf() to clean up
various bits of code which used ap_snprintf()/pstrdup().
[Dean Gaudet]
*) PORT: HAVE_SNPRINTF doesn't do anything any longer. This is because
ap_snprintf() has different semantics and formatting codes than
snprintf(). [Dean Gaudet]
*) SIGXCPU and SIGXFSZ are now reset to SIG_DFL at boot-time. This
is necessary on at least Solaris where the /etc/rc?.d scripts
are run with these signals ignored, and "SIG_IGN" settings are
maintained across exec().
*) Fix the check for symbolic links in ``RewriteCond ... -l'': stat() was
used instead of lstat() and thus this flag didn't work as expected.
*) Fix the proxy pass-through feature of mod_rewrite for the case of
existing QUERY_STRING now that mod_proxy was recently changed because of
the new URL parsing stuff. [Ralf S. Engelschall]
*) A few changes to scoreboard definitions which helps gcc generate
better code. [Dean Gaudet]
*) ANSI C doesn't guarantee that "int foo : 2" in a structure will
be a signed bitfield. So mark a few bitfields as signed to
ensure correct code. [Dean Gaudet]
*) The default for HostnameLookups was changed to Off, but there
was a problem and it wasn't taking effect. [Dean Gaudet]
*) PORT: Clean up undefined signals on some platforms (SCO, BeOS).
[Dean Gaudet]
*) After a SIGHUP the listening sockets in the parent weren't
properly marked for closure on fork().
*) Allow %2F in two situations: 1) it is in the query part of the URI,
therefore not exposed to %2F -> '/' translations and 2) the request
is a proxy request, so we're not dealing with a local resource anyway.
Without this, the proxy would fail to work for any URL's with
%2f in them (occurs quite often in
http://.../cgi-bin/...?http%3A%2F%2F... references) [Martin Kraemer]
*) Protect against FD_SETSIZE mismatches. [Dean Gaudet]
*) Make the shared object compilation command more portable by avoiding
the direct combination of `-c' & `-o' which is not honored by some
compilers like UnixWare's cc. [Ralf S. Engelschall]
*) WIN32: the proxy was creating filenames missing the last four
characters. While this normally doesn't stop anything from
working, it can result in extra collisions.

*) Now mod_proxy uses the response string (in addition to the response status
code) from the already used FTP SIZE command to setup the Content-Length
header if available. [Ralf S. Engelschall] PR#1183
*) Reanimated the (still undocumented) proxy receive buffer size directive:
Renamed from ReceiveBufferSize to ProxyReceiveBufferSize because the old
name was really too generic, added documentation for this directive to
the mod_proxy.html and corrected the hyperlink to it in the
new_features_1.3.html document. [Ralf S. Engelschall] PR#1348
*) Fix a bug in the src/helpers/fp2rp script and make it a little bit
faster [Martin Kraemer]
*) Make Configure die when you give it an unknown command switch.
[Ben Hyde]
*) Add five new and fresh manpages for the support programs: dbmmanage.1,
suexec.8, htdigest.1, rotatelogs.8 and logresolve.8. Now all up-to-date
and per default compiled support programs have manual pages - just to
document our stuff a little bit more and to be able to do really
Unix-like installations ;-) [Ralf S. Engelschall]
*) Major cleanups to the Configure script to make it and its generated
Makefiles again readable and maintainable: add SRCDIR option, removed
INCLUDES_DEPTH[0-2] kludge, cleanup of TARGET option, cleanup of
generated sections, consequently added Makefile headers with inheritance
information, added subdir movement messages for easier following where
the build process currently stays (more verbose then standard Make, less
verbose than GNU make), same style to comments in the Configure script,
added Apache license header, fixed a few bugs, etc. [Ralf S. Engelschall]
*) Add the new ApacheBench program "ab" to src/support/: This is derived
from the ZeusBench benchmarking program and can be used to determine the
response performance of an Apache installation. This version is
officially licensed with Zeus Technology, Ltd. See the license agreement
statements in <199803171224.NAA24547 en1.engelschall.com> in apache-core.

*) API: Various core functions that are definately not part of the API
have been made static, and a few have been marked API_EXPORT. Still
more have been marked CORE_EXPORT and are not intended for general
use by modules. [Doug MacEachern, Dean Gaudet]
*) mod_proxy was not clearing the Proxy-Connection header from
requests; now it does. This did not violate any spec, however
causes poor interactions when you are talking to remote proxies.
[Marc Slemko] PR#1741
*) Various cleanups to the command line interface and manual pages.
[Ralf S. Engelschall]
*) cfg_getline() was not properly handling lines that did not end
with a line termination character. [Marc Slemko] PR#1869, 1909
*) Performance tweak to mod_log_config. [Dmitry Khrustalev]
*) Clean up some undocumented behavior of mod_setenvif related to
"merging" two SetEnvIf directives when they match the same header
and regex. Document that mod_setenvif will perform comparisons in
the order they appear in the config file. Optimize mod_setenvif by
doing more work at config time rather than at runtime.
[Dean Gaudet]
*) src/include/ap_config.h now wraps it's #define's with #ifndef/#endif's
to allow for modules to overrule them and to reduce redefinition
warnings [Jim Jagielski]
*) [PORT] For A/UX change the OS-#define for -DAUX to -DAUX3.
[Jim Jagielski]
*) Making the hard-coded cross-module function call mime_find_ct() (from
mod_proxy to mod_mime) obsolete by making sure the API hook for MIME type
checking is really called even for proxy requests except for URLs with
HTTP schemes (because there we can optimize by not running the type
checking hooks due to the fact that the proxy gets the MIME Content-type
from the remote host later). This change cleans up mod_mime by removing
the ugly export kludge, makes the one-liner file mod_mime.h obsolete, and
especially unbundles mod_proxy and mod_mime. This way they both now can
be compiled as shared objects and are no longer tied together.
[Ralf S. Engelschall]
*) util.c cleanup and speedup. [Dean Gaudet]
*) API: Clarification, pstrndup() will always copy n bytes of the source
and NUL terminate at the (n+1)st byte. [Dean Gaudet]
*) Mark module command_rec and handler_rec structures const so that they
end up in the read-only data section (and are friendlier to systems
that don't do optimistic memory allocation on fork()). [Dean Gaudet]
*) Add check to the "Port" directive to make sure the specified
port is in the appropriate range. [Ben Hyde]
*) Performance improvements to invoke_handler().

*) Added support for building shared objects even for library-style modules
(which are built from more than one object file). This now provides the
ability to build mod_proxy as a shared object module. Additionally
modules like mod_example are now also supported for shared object
building because the generated Makefiles now no longer assume there is at
least one statically linked module. [Ralf S. Engelschall]
*) API: Clarify usage of content_type, handler, content_encoding,
content_language and content_languages fields in request_rec. They
must always be lowercased; and the strings pointed to shouldn't
be modified (you must copy them to modify them). Fix a few bugs
related to this. [Dean Gaudet]
*) API: Clarification: except for RAW_ARGS, all command handlers can
treat the char * parameters as permanent, and modifiable. There
is no need to pstrdup() them. Clean up some needless pstrdup().
[Dean Gaudet]
*) Now mod_so keeps track of which module shared objects with which names
are loaded and thus avoids multiple loading and unloading and irritating
error_log messages. [Ralf S. Engelschall]
*) Prior to the existence of mod_setenv it was necessary to tweak the TZ
environment variable in the apache core. But that tweaking interferes
with mod_setenv. So don't tweak if the user has specified an explicit
*) rputs() did not calculate r->sent_bodyct properly.
*) The CGI spec says that REMOTE_HOST should be set to the remote hosts's
name, or left unset if this value is unavailable. Apache was setting
it to the IP address when unavailable.

*) Various improvements to the configuration and build support for compiling
modules as shared objects. Especially Solaris 2.x, SunOS 4.1, IRIX and
OSF1 support with GCC and vendor compilers was added. This way shared
object support is now provided out-of-the-box for FreeBSD, Linux,
Solaris, SunOS, IRIX and OSF1. In short: On all major platforms!
[Ralf S. Engelschall]
*) Minor cleanup in http_main -- split QNX and OS2 specific "mmap"
scoreboard code into separate #defines -- USE_POSIX_SCOREBOARD
and USE_OS2_SCOREBOARD. [Dean Gaudet]
*) Fix one more special locking problem for RewriteMap programs in
mod_rewrite: According to the documentation of flock(), "Locks are on
files, not file descriptors. That is, file descriptors duplicated
through dup(2) or fork(2) do not result in multiple instances of a lock,
but rather multiple references to a single lock. If a process holding a
lock on a file forks and the child explicitly unlocks the file, the
parent will lose its lock.". To overcome this we have to make sure the
RewriteLock file is opened _AFTER_ the childs were spawned which is now
the case by opening it in the child_init instead of the module_init API
hook. [Ralf S. Engelschall] PR#1029
*) Change to Location and LocationMatch semantics. LocationMatch no
longer lets a single slash match multiple adjacent slashes in the
URL. This change is for consistency with RewriteRule and
AliasMatch. Multiple slashes have meaning in URLs that they do
not have in (some) filesystems. Location on the other hand can
be considered a shorthand for a more complicated regex, and it
does match multiple slashes with a single slash -- which is
also consistent with the Alias directive.
[Dean Gaudet] related PR#1440
*) Fix bug with mod_mime_magic causing certain files, including files
of length 0, to result in no response from the server.
[Dean Gaudet]
*) The Configure script now generates src/include/ap_config.h which
contains the set of defines used when Apache is compiled on a platform.
This file can then be included by external modules before including
any Apache header files in case they are being built separately from
Apache. Along with this change, a couple of minor changes were
made to make Apache's #defines coexist peacefully with any autoconf
defines an external module might have. [Rasmus Lerdorf]
*) Fix mod_rewrite for the ugly API case where <VirtualHost> sections exist
but without any RewriteXXXXX directives. Here mod_rewrite is given no
chance by the API to initialize its per-server configuration and thus
receives the wrong one from the main server. This is now avoided by
remembering the server together with the config structure while
configuring and later assuming there is no config when we see a
difference between the remembered server and the one calling us.
[Ralf S. Engelschall] PR#1790
*) Fixed the DBM RewriteMap support for mod_rewrite: First the support now
is automatically disabled under configure time when the dbm_xxx functions
are not available. Second, two heavy source code errors in the DBM
support code were fixed. This makes DBM RewriteMap's usable again after
a long time of brokenness. [Ralf S. Engelschall] PR#1696
*) Now all configuration files support Unix-style line-continuation via
the trailing backslash ("\") character. This enables us to write down
complex or just very long directives in a more readable way. The
backslash character has to be really the last character before the
newline and it has not been prefixed by another (escaping) backslash.

*) To deal with modules being compiled and [dynamically] linked
at a different time from the core, the SERVER_VERSION and
SERVER_BUILT symbols have been abstracted through the new
API routines apapi_get_server_version() and apapi_get_server_built().

*) WIN32: Preserve trailing slash in canonical path (and hence
in PATH_INFO). [Paul Sutton, Ben Laurie]
*) PORT: USE_PTHREAD_SERIALIZED_ACCEPT has proven unreliable
depending on the rev of Solaris and what mixture of modules
are in use. So it has been disabled, and Solaris is back to
using USE_FCNTL_SERIALIZED_ACCEPT. Users may experiment with
USE_PTHREAD_SERIALIZED_ACCEPT at their own risk, it may speed
up static content only servers. Or it may fail unpredictably.

*) mod_test_util_uri.c created which tests the logic in util_uri.c.
[Dean Gaudet]
*) API: Rewrite of absoluteURI handling, and in particular how
absoluteURIs match vhosts. Unless a request is a proxy request, a
"http://host" url is treated as if a similar "Host:" header had been
supplied. This change was made to support future HTTP/1.x protocols
which may require clients to send absoluteURIs for all requests.
In order to achieve this change subtle changes were made to the API. In a
request_rec, r->hostlen has been removed. r->unparsed_uri now exists so
that the unmodified uri can be retrieved easily. r->proxyreq is not set
by the core, modules must set it during the post_read_request or
translate_names phase.
Plus changes to the virtualhost test suite for absoluteURI testing.
This fixes several bugs with the proxy proxying requests to vhosts
managed by the same httpd.
[Dean Gaudet]
*) API: Cleanup of code in http_vhost.c, and remove vhost matching
code from mod_rewrite. The vhost matching is now performed by a
globally available function matches_request_vhost(). [Dean Gaudet]
*) Reduce memory usage, and speed up ServerAlias support. As a
side-effect users can list multiple ServerAlias directives
and they're all considered.
*) The "poly" directive in image maps did not include the borders of the
polygon, whereas the "rect" directive does. Fix this inconsistency.
*) Add the `%a' construct to LogFormat and CustomLog to log the client IP

*) API: A new source module main/util_uri.c; It contains a routine
parse_uri_components() and friends which breaks a URI into its component
parts. These parts are stored in a uri_components structure called
parsed_uri within each request_rec, and are available to all modules.
Additionally, an unparse routine is supplied which re-assembles the URI
components back to an URI, optionally hiding the username:password@ part
from ftp proxy requests, and other useful routines. Within the structure,
you find on a ready-for-use basis:
scheme; /* scheme ("http"/"ftp"/...) */
hostinfo; /* combined [user[:password]@]host[:port] */
user; /* user name, as in http://user:passwd@host:port/ */
password; /* password, as in http://user:passwd@host:port/ */
hostname; /* hostname from URI (or from Host: header) */
port_str; /* port string (integer representation is in "port") */
path; /* the request path (or "/" if only scheme://host was given) */
query; /* Everything after a '?' in the path, if present */
fragment; /* Trailing "#fragment" string, if present */
This is meant to serve as the platform for *BIG* savings in
code complexity for the proxy module (and maybe the vhost logic).

*) Make all possible meta-construct expansions ($N, %N, %{NAME} and
${map:key}) available for all location where a string is created in
mod_rewrite rewriting rulesets: 1st arg of RewriteCond, 2nd arg of
RewriteRule and for the [E=NAME:STRING] flag of RewriteRule. This way the
possible expansions are consequently usable at all string creation
locations. [Ralf S. Engelschall]
*) Fix initialization of RewriteLogLevel (default now is 0 as documented
and not 1) and the per-virtual-server merging of directives. Now all
directives except `RewriteEngine' and `RewriteOption' are either
completely overridden (default) or completely inherited (when
`RewriteOptions inherit') is used. [Ralf S. Engelschall] PR#1325
*) Fix `RewriteMap' program lookup in situations where such maps are
defined but disabled (`RewriteEngine off') in per-server context.
[Ralf S. Engelschall] PR#1431
*) Fix bug introduced in 1.3b4-dev, config with no Port setting would cause
server to bind to port 0 rather than 80. [Dean Gaudet]
*) Fix long-standing problem with RewriteMap _programs_ under Unix derivates
(like SunOS and FreeBSD) which don't accept the locking of pipes
directly. A new directive RewriteLock is introduced which can be used to
