*) Make the error bucket a real meta-data bucket. This means that the
bucket length is 0, and a read returns NULL data. If one of these
buckets is passed down after the headers are sent, this data will
just be ignored. [Greg Stein]
*) The prefork MPM wasn't killing child processes correctly if a restart
signal was received while the process was serving a request. The child
process would become the equivalent of a second parent process. If
we break out of the accept loop, then we need to do die after cleaning
up after ourselves. [Ryan Bloom]
*) Change the Prefork MPM to use SIGWINCH instead of SIGUSR1 for graceful
restarts. [Ryan Bloom]
*) Modify the apr_stat/lstat/getfileinfo calls within apache to use
the most optimal APR_FINFO_wanted bits. This spares Win32 from
performing very expensive owner, group and permission lookups
and allows the server to function until these apr_finfo_t fields
are implemented under Win32. [William Rowe]
*) Support for typedsafe optional functions - that is functions exported by
optional modules, which, therefore, may or may not be present, depending
on configuration. See the experimental modules mod_optional_fn_{ex,im}port
for sample code. [Ben Laurie]
*) filters can now report an HTTP error to the server. This is done
by sending a brigade where the first bucket is an error_bucket.
This bucket is a simple bucket that stores an HTTP error and
a string. Currently the string is not used, but it may be needed
to output an error log. The http_header_filter will find this
bucket, and output the error text, and then return
AP_FILTER_ERROR, which informs the server that the error web page
has already been sent. [Ryan Bloom]
*) If we get an error, then we should remove all filters except for
those critical to serving a web page. This fixes a bug, where
error pages were going through the byterange filter, even though
that made no sense. [Ryan Bloom]
*) Relax the syntax checking of Host: headers in order to support
iDNS. PR#6635 [Tony Finch]
*) Cleanup the byterange filter to use the apr_brigade_partition
and apr_bucket_copy functions. This removes a lot of very messy
code, and hopefully makes this filter more stable.
[Ryan Bloom]
*) Remove AddModule and ClearModuleList directives. Both of these
directives were used to ensure that modules could be enabled
in the correct order. That requirement is now gone, because
we use hooks to ensure that modules are in the correct order.
[Ryan Bloom]
*) When SuExec is specified, we need to add it to the list of
targets to be built. If we don't, then any changes to the
configuration won't affect SuExec, unless 'make suexec' is
specifically run. [Ryan Bloom]
*) Cleaned out open_file from mod_file_cache, as apr now accepts
the APR_XTHREAD argument to open a file for consumption by
parallel threads on win32. [William Rowe]
*) Correct a bug in determining when we follow symlinks. The code
expected a stat -1 result, not an apr_status_t positive error.
Also check if the APR_FINFO_USER fields are valid before we
follow the link. [William Rowe]
*) Move initgroupgs, ap_uname2id and ap_gname2id from util.c to
mpm_common.c. These functions are only valid on some platforms,
so they should not be in the main-line code. [Ryan Bloom]
*) Remove ap_chdir_file(). This function is not thread-safe,
and nobody is currently using it. [Ryan Bloom]
*) Do not try to run make depend if there are no .c files in the
current directory, doing so makes `make depend` fail.
[Ryan Bloom]
*) Update highperformance.conf to work with either prefork or
pthreads mpms. [Greg Ames]
*) Stop checking to see if this is a pipelined request if we know
for a fact that it isn't. Basically, if r->connection->keepalive == 0.
This keeps us from making an extra read call when serving a 1.0
request. [Ryan Bloom and Greg Stein]
*) Fix the handling of variable expansion look-ahead in mod_rewrite,
i.e. syntax like %{LA-U:REMOTE_USER}, and also fix the parsing of
more complicated nested RewriteMap lookups. PR#7087 [Tony Finch]
*) Fix the RFC number mentioned when complaining about a missing
Host: header. PR#7079 [Alexey Toptygin <alexeyt@wam.umd.edu>]
*) Fix an endless loop in ab which occurred when ab was posting
and the server dropped the connection unexpectedly.
[Jeff Trawick]
*) Fix a segfault while handling request bodies in ap_http_filter().
This problem has been seen with mod_dav usage as well as with
requests where the body was just being discarded. [Jeff Trawick]
*) Some adjustment on the handling and automatic setting (via
hints.m4) of various compilation flags (eg: CFLAGS). Also,
add the capability to specify flags (NOTEST_CFLAGS and
NOTEST_LDFLAGS) which are used to compile Apache, but
not used during the configuration process. Useful for
flags like "-Werror". [Jim Jagielski]
*) Stop using environment variables to force debug mode or
no detach. We now use the -D command line argument to
specify the correct mode. -DONE_PROCESS and -DNO_DETACH.
*) Change handlers to use hooks. [Ben Laurie]
*) Stop returning copies of filenames from both apr_file_t and
apr_dir_t. We pstrdup the filenames that we store in the
actual structures, so we don't need to pstrdup the strings again.
[Ryan Bloom]
*) mod_cgi: Fix some problems where the wrong error value was being
traced. [Jeff Trawick]
*) EBCDIC: Fix some missing ASCII conversion on some protocol data.
[Jeff Trawick]
*) Add generic hooks. [Ben Laurie]
*) Use a real pool to dup the error log descriptor. [Ryan Bloom]
*) Fix a segfault caused by mod_ext_filter when the external filter
program does not exist. [Jeff Trawick]
*) Fix an output truncation error when on an HTTP >= 1.0 request an
object of size between DEFAULT_BUCKET_SIZE and AP_MIN_BYTES_TO_WRITE
was served through mod_charset_lite (or anything else that would
create a transient bucket in this size range). ap_bucket_make_heap()
silently failed (fixed), transient_setaside() discovered it, but
ap_save_brigade() ignored it (fixed). [Jeff Trawick]
*) Ignore \r\n or \n when using PEEK mode for input filters. The problem
is that some browsers send extra lines at the end of POST requests, and
we don't want to delay sending data back to the user just because the
browser isn't well behaved. [Ryan Bloom]
*) Get SuEXEC working again. We can't send absolute paths to suExec
because it refuses to execute those programs. SuEXEC also wasn't
always recognizing configuration changes made using the autoconf
setup. [Ryan Bloom]
*) Allow the buildconf process to find the config.m4 files in the correct
order. Basically, we can now name config.m4 files as config\d\d.m4,
and we will sort them correctly when inserting them into the build
process. [Ryan Bloom]
*) Get mod_cgid to use apr calls for creating the actual CGI process.
This also allows mod_cgid to use ap_os_create_priviledged_process,
thus allowing for SuExec execution from mod_cgid. Currently, we do
not support everything that standard SuExec supports, but at least
it works minimally now. [Ryan Bloom]
*) Allow SuExec to be configured from the ./configure command line.
[Ryan Bloom]
*) Update some of the docs in README and INSTALL to reflect some of
the changes in Apache 2.0 [Cliff Woolley <cliffwoolley@yahoo.com>]
*) If we get EAGAIN returned from the call to apr_sendfile, then we
need to call sendfile again. This gets us serving large files
such as apache_2.0a9.tar.gz on FreeBSD again. [Ryan Bloom]
*) Get the support programs building cleanly again.
[Cliff Woolley <cliffwoolley@yahoo.com>]
*) The Apache/Win32 Apache.exe and dll's now live in bin. The
current directory logic now backs up over bin/ to determine the
server root from the Apache.exe path.
*) Apache/Win32 now follows the standard conventions of mod_foo.so
loadable modules, dynamic libs are all named libfoo.dll, and the
makefile.win populates the include, lib and libexec directories.
*) Apache is now IPv6-capable. On systems where APR supports IPv6,
Apache gets IPv6 listening sockets by default. Additionally, the
Listen, NameVirtualHost, and <VirtualHost> directives support IPv6
numeric address strings (e.g., "Listen [fe80::1]:8080").
[Jeff Trawick]
*) Modify the install directory layout. Modules are now installed in
modules/. Shared libraries should be installed in libraries/, but
we don't have any of those on Unix yet. All install directories
are modifyable at configure time. [Ryan Bloom]
*) Install all header files in the same directory on Unix. [Ryan Bloom]
*) Get the functions in server/linked into the server, regardless of
which modules linked into the server. This uses the same hack
for Apache that we use for APR and apr-util to ensure all of the
Loading full blame...
