Changes with Apache 2.0.12-dev
*) Move the threaded MPM to use APR locks instead of pthread locks.
[Ryan Bloom]
*) Rename mpmt_pthread to threaded. This is more in line with the
fact that mpmt_pthread shouldn't be using pthreads directly, and
it is a smaller name that doesn't tie into anything.
[Ryan Bloom]
*) Rename the module structures so that the exported symbol matches
the file name, and it is easier to automate the installation
process (generating LoadModule directives from the module filenames).
[Martin Kraemer]
*) Remove the coalesce filter. With the ap_f* functions, this filter
is no longer needed. [Ryan Bloom]
Changes with Apache 2.0.11
*) Remove the dexter MPM. Perchild is the same basic idea, but it has the
added feature of allowing a uid/gid per child process. If no
uid/gid is specified, then Perchild behaves exactly like dexter.
[Ryan Bloom]
*) Don't disable threads just because we are using the prefork MPM.
If somebody wants to compile without threads, they must now add
--disable-threads to the configure command line. [Ryan Bloom]
*) Begin to move the calls to update_child_status into common code, so
that each individual MPM does not need to update the scoreboard itself.
[Ryan Bloom]
*) Allow mod_tls to compile under Unix boxes where openssl has been
installed to the system include files.
[Gomez Henri <new-httpd@slib.fr>]
*) Cleanup the mod_tls configure process. This should remove any need
to hand-edit any files. We require OpenSSL 0.9.6 or later, but
configure doesn't check that yet. [Ryan Bloom]
*) Add a very early prototype of SSL support (in mod_tls.c). It is
vital that you read modules/tls/README before attempting to build
it. [Ben Laurie]
*) Fix a potential seg fault on all platforms. David Reid fixed this
on BEOS, but the problem could happen anywhere, so we don't want
to #ifdef it. [Cliff Woolley <cliffwoolley@yahoo.com>]
*) Add new LogFormat directive, %D, to log time it takes to serve a
request in microseconds. [Bill Stoddard]
*) Change AddInputFilter and AddOutputFilter to SetInputFilter and
SetOutputFilter. This corresponds nicely with the other Set
directives, which operate on containers while the Add* directives
tend to work directly on extensions. [Ryan Bloom]
*) Cleanup the header handling a bit. This uses the apr_brigade_*
functions for the buffering so that we don't need to compute
the length of the headers before we actually create the header
buffer. [Ryan Bloom]
*) Allow filters to buffer data using the ap_f* functions. These have
become macros that resolve directly to apr_brigade_*.
[Ryan Bloom]
*) Get the Unix MPM's to do a graceful restart again. If we are going
to register a cleanup with ap_cleanup_scoreboard, then we have to
kill the cleanup with the same function, and that function can't be
static. [Ryan Bloom]
*) Install all required header files. Without these, it was not
possible to compile some modules outside of the server.
[Ryan Bloom]
*) Fix the AliasMatch directive in Apache 2.0. When we brought a patch
forward from 1.3 to 2.0, we missed a single line, which broke regex
aliases. [Ryan Bloom]
*) We have a poor abstraction in the protocol. This is a temporary
hack to fix the bug, but it will need to be fixed for real. If
we find an error while sending out a custom error response, we back
up to the first non-OK request and send the data. Then, when we send
the EOS from finalize_request_protocol, we go to the last request,
to ensure that we aren't sending an EOS to a request that has already
received one. Because the data is sent on a different request than
the EOS, the error text never gets sent down the filter stack. This
fixes the problem by finding the last request, and sending the data
with that request. [Ryan Bloom]
*) Make the server status page show the correct restart time, and
thus the proper uptime. [Ryan Bloom]
*) Move the CGI creation logic from mod_include to mod_cgi(d). This
should reduce the amount of duplicate code that is required to
create CGI processes.
[Paul J. Reder <rederpj@raleigh.ibm.com>]
*) ap_new_connection() closes the socket and returns NULL if a socket
call fails. Usually this is due to a connection which has been
reset. [Jeff Trawick]
*) Move the Apache version information out of httpd.h and into release.h.
This is in preparation for the first tag with the new tag and release
system. [Ryan Bloom]
*) Begin restructuring scoreboard code to enable adding back in
the ability to use IPC other than shared memory.
Get mod_status working on Windows again. [Bill Stoddard]
*) Make mod_status work with 2.0. This will work for prefork,
mpmt_pthread, and dexter. [Ryan Bloom]
*) Correct a typo in httpd.conf.
[Kunihiro Tanaka <tanaka@apache.or.jp>] PR#7154
*) Really fix mod_rewrite map lookups this time. [Tony Finch]
*) Get the correct IP address if ServerName isn't set and we can't
find a fully-qualified domain name at startup.
PR#7170 [Danek Duvall <dduvall@eng.sun.com>]
*) Make mod_cgid work with SuExec. [Ryan Bloom]
*) Adopt apr user/group name features for mod_rewrite. Eliminates some
'extra' stat's for user/group since they should never occur, and now
resolves the SCRIPT_USER and SCRIPT_GROUP, including on WinNT NTFS
volumes. [William Rowe]
*) Adopt apr features to simplify mod_includes. This changes the
behavior of the USER_NAME variable, unknown uid's are now reported
as USER_NAME="<unknown>" rather than the old user#000 result.
WinNT now resolves USER_NAME on NTFS volumes. [William Rowe]
*) Adopt apr features for simplifing mod_userdir, and accept the new
Win32/OS2 exceptions without hiccuping. [William Rowe]
*) Replace configure --with-optim option by using and saving the
environment variable OPTIM instead. This is needed because configure
options do not support multiple flags separated by spaces.
[Roy Fielding]
*) Fix some byterange handling. If we get a byte range that looks like
"-999999" where that is past the end of the file, we should return
a PARTIAL CONTENT status code, and return the whole file as one big
byterange. This matches the 1.3 handling now. [Ryan Bloom]
*) 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.
