Changes with Apache 2.0.19-dev
*) apxs no longer generates ap_send_http_header() in the example handler
*) Fix an ab problem which could cause a divide-by-zero exception
with certain invocations (e.g., ab -k -c 6 -n 100 localhost/).
[Ian Holsman <ianh@cnet.com>]
*) Solve case-insensitive platforms' confusion about negotiated
filenames, allowing files of differnt case to match in choosing
the document to serve. [William Rowe]
*) Fix brokenness when ThreadsPerChild is higher than the built-in
limit. We left ap_threads_per_child at the higher value which
led to segfaults when doing certain scoreboard operations.
[Jeff Trawick]
*) Fix seg faults and/or missing output from mod_include. The
default_handler was using the subrequest pool for files and
MMAPs, even though the associated APR structures typically
live longer than the subrequest. [Greg Ames]
*) Extend mod_setenvif to support specifying regular expressions
on the SetEnvIf (and SetEnvIfNoCase) directive attribute field.
Example: SetEnvIf ^TS* [a-z].* HAVE_TS
will cause HAVE_TS to be set if any of the request headers begins
with "TS" and has a value that begins with any character in the
set [a-z]. [Bill Stoddard]
*) httpd children now re-bind themselves to a random CPU on
multiprocessor systems on AIX via bindprocessor() in 2.0.
[Victor J. Orlikowski]
*) Fix htdigest. It would go into a loop in getline when adding
a second user. [Bill Stoddard]
*) Win32 platforms now fully support mod_userdir options. [Will Rowe]
*) Automatically generate httpd.exp for AIX.
*) Add a new request hook, error_log. This phase allows modules
to act on the error log string _after_ it has been written
to the error log. The goal for this hook is to allow monitoring
modules to send the error string to the monitoring agent.
[Ryan Bloom]
*) Modify mod_echo to make it use filters for input and output.
[Ryan Morgan <rmorgan@covalent.net>]
*) Extend mod_headers to support conditional driven Header
add, append and set. Use SetEnvIf to set an envar and conditionally
add/append/set headers based on this envar thusly:
SetEnvIf TSMyHeader value HAVE_TSMyHeader
Header add MyHeader "%t %D" env=HAVE_TSMyHeader
If the request contains header "TSMyHeader: value" then header
MyHeader: "t=xxxxxxxxxx D=yyyy" will be sent on the response.
[Bill Stoddard]
*) Extend mod_headers to support using format specifiers on Header
add, append and set header values. Two format specifiers are supported:
%t - reports, in UTC microseconds since the epoch, when the
request was received.
%D - reports the time, in microseconds, between when the request was
received and the response sent.
Examples:
Header add MyHeader "This request served in %D microseconds. %t"
results in a header being added to the response that looks like this:
MyHeader: This request served in D=5438 microseconds. t=991424704447256
[Bill Stoddard]
*) Fix reset_filter(). We need to be careful how we remove filters.
If we set r->output_filters to NULL, we also have to reset the
connection's filters. [John Sterling]
*) Optimise reset_filter() in http_protocol.c. [Greg Stein]
*) Add a check to ap_die() to make sure the filter stack is sane and
contains the correct basic filters when an error occurs. This fixes
a problem where headers are not being sent on error. [John Sterling]
*) New Header directive 'echo' option. "Header echo regex" will
cause any headers received on the request that match regex to be
echoed to (included in) the response headers.
[Bill Stoddard]
*) include/ap_compat.h tested and set APR_COMPAT_H instead of AP_COMPAT_H.
This prevented the inclusion of apr_compat.h. PR #7773
[Oleg Broytmann <phd@phd.pp.ru>]
*) Moved util_uri to the apr-util library. This required a bunch of
apr_name changes for the uri utility functions. [Justin Erenkrantz]
*) Move the addition of default AP_HTTP_HTTP_HEADER filters to the
insert_filter phase so that other filters are not bypassed by default.
[Graham Leggett]
*) Reimplement mod_headers as an output filter. mod_headers can now
add custom headers to inbound requests using the RequestHeader directive
and to responses using the same old Header directive. [Graham Leggett]
Changes with Apache 2.0.18
*) Fix command-line processing so that if a bad argument is specified
Apache will exit. [Jeff Trawick]
*) Change the make targets and rules to be consistent in all of the
Apache-owned source trees. [Roy Fielding]
*) Fix processing of the TRACE method. Previously we passed bogus
parms to form_header_field() and it overlaid some vhost structures,
resulting in a segfault in check_hostalias().
[Greg Ames, Jeff Trawick]
*) Win32: Add support for reliable piped logs. If the logging process
goes down, Apache will automatically restart it. This function has
been part of Apache on Unix/Linux/BSD since the early v1.3 releases.
[Bill Stoddard]
*) Do not start piped log processes during the config file
preflight. This change also circumvents a problem on
Windows where the rotatelog processes created during preflight
was not getting cleaned up properly.
[Bill Stoddard]
*) add "Request Phase Participation" info to mod_info
[Doug MacEachern]
*) Make first phase changes to the scoreboard data structures in
preparation for the rewriting of the scoreboard per my posted
design notes. [Paul J. Reder]
*) Fix httpd's definition of LTFLAGS to be consistent with that of apr
and apr-util, allow it to be overridden by the configure command-line
(default="--silent") and introduce LT_LDFLAGS to replace what we were
formerly abusing as LTFLAGS. [Roy Fielding]
*) Clean up the reporting of incorrect closing container tags.
[Barrie Slaymaker <barries@slaysys.com>]
*) Simplify the configure process by moving all libtool stuff to APR
and moving hints.m4 inline. [Roy Fielding]
*) Add the AP_DECLARE()/AP_CORE_DECLARE macros on the return types
of functions used by mod_proxy for export in the DLL
[Ian Holsman <IanH@cnet.com>]
*) Prevent a hang when a cgi handled by mod_cgid tries to read a
request body from its stdin but no reqest body is being written to
the cgi. [Jeff Trawick]
*) mod_log_config: %c connection status incorrectly logged
as "-" (non-keepalive) when MaxKeepAliveRequests is set to 0.
[Bill Stoddard]
*) Get mod_cern_meta working under Windows
[Bill Stoddard]
*) Create Files, and thus MMAPs, out of the request pool, not the
connection pool. This solves a small resource leak that had us
not closing files until a connection was closed. In order to do
this, at the end of the core_output_filter, we loop through the
brigade and convert any data we have into a single HEAP bucket
that we know will survive clearing the request_rec.
[Ryan Bloom, Justin Erenkrantz <jerenkrantz@ebuilt.com>,
Cliff Woolley]
*) Completely revamp configure so that it preserves the standard make
variables CPPFLAGS, CFLAGS, CXXFLAGS, LDFLAGS and LIBS by moving
the configure additions to EXTRA_* variables. Also, allow the user
to specify NOTEST_* values for all of the above, which eliminates the
need for THREAD_CPPFLAGS, THREAD_CFLAGS, and OPTIM. Fix the setting
of INCLUDES and EXTRA_INCLUDES. Check flags as they are added to
avoid pointless duplications. Fix the order in which flags are given
on the compile and link lines. Remove obsolete macros APR_DOEXTRA,
AC_ADD_LIBRARY, AC_CHECK_DEFINE, APACHE_PASSTHRU, and APACHE_ONCE.
Added APR_SAVE_THE_ENVIRONMENT and APR_RESTORE_THE_ENVIRONMENT macros.
Renamed AC_TYPE_RLIM_T macro to APACHE_TYPE_RLIM_T. [Roy Fielding]
*) Get mod_tls to compile/work better on Windows. PR #7612
[Bernhard Schrenk <b.schrenk@improx.com>]
*) Fix shutdown/restart hangs in the threaded MPM.
[Jeff Trawick, Greg Ames, Ryan Bloom]
*) Removed the keptalive boolean from conn_rec because it is now only
used by a single routine and can be replaced by a local variable.
[Greg Stein, Ryan Bloom, Roy Fielding]
*) Patch prefork to put enough of the signal processing back in so that
signals are all handled properly now. The previous patch fixed the
