MAJOR charset encoding fixes. The file names and HTTP-Equiv tags are now
in sync with the httpd-std.conf - and the ucs2/4 encodings are gone since
utf8 is a universally recognized shorthand that sits much better in our
tree [notice; these were _duplicate_ character sets, only in different
byte encodings!] Same with removing the duplicate .jis and .is-kr files.
[I simply choose the one 'with link' over the one without, and fixed the
links back to preFAQ as I picked.]
Russian users, how many of the remaining five encodings are truly needed?
Overhaul the compatibility with 1.3's subrequest and redirect processing.
Eliminate URI-centric phases in ap_process_request_internal() for pure
file subrequests (that don't correspond to URI space.) translate_name
hook and location_walks are skipped for these requests.
Moves the reset of the per_dir_config out of directory_walk into the
internal request processing code, so that resources with alternate
map_to_storage requirements start with clean r->server->lookup_defaults.
Optimizes out the authn/authz of effectively identical subreqests and
redirects, as the sub_req_lookup calls once did. Unlike 1.3, we copy
r->user and r->ap_auth_type from main/prev for the request's reference.
Stop copying the subrequest's r->chunked flag (Rbb assured me it looked
bogus, chunking is on the parent request) and clean out other #if 0'ed
cruft we don't need to refer back to anymore.
Immortal data should go in an immortal bucket, not a pool bucket. It would
still work in a pool bucket, but only by coincidence. At the very least, a
pool bucket is way more overhead than this poor unsuspecting little CRLF

Joy, joy. Relax the rules, just a wee bit, and prepare to move the fatal

give older, ported modules more time to cope without implementing

revert buckets sms phase 1 patch. the group wants to get rid of SMS, so
the buckets can't use it. I'll implement a free-list scheme private

kill -l requires the short version of the signal (without SIG prefix).
(apachectl graceful was broken.)
The best way to do this is to change configure to internally represent
the signal without the SIG prefix and prepend SIG before substitution
(and export a version without the SIG prefix for apachectl).
This highlights why we want to move apachectl's core functionality into
httpd.
AFAICT, we have never created server configs of _all_ modules for _all_
contexts, only when they come up (e.g., a directive of that particular
module is provided) with the except that vhost containers complete the
initialization of all modules. I haven't stepped this, but it appears
to be correct.
This patch assures we can merge two incomplete directory sections
together. They will (obviously) need to be merged with a LHS default,
e.g. a vhost's or main server's default dir config. That's fine, this
just allows either the LHS or RHS value to be null, and for merging to
still succeed.

Currently, when the map-to-storage handler for TRACE returns DONE, the
caller -- ap_process_request_internal() -- catches that and returns
OK to its caller -- ap_process_request(). But ap_process_request(),
seeing OK, tries to run a handler. It needs to skip that if the
request was completed in ap_process_request_internal().

There is still some stuff I'd like to do here, but I'll commit what
I have for the moment. I've done three things:
1. Emphasize that auth does not need to be in .htaccess.
2. Add detailed discussion of each of the auth directives (does this
belong here?)
3. Remove the AuthGroupFile /dev/null which shouldn't be necessary.

Fix case where an included file may change but the shtml file has not -
since we returned Last-Modified/ETag headers, we said that it was possibly
cacheable. Wrong.
See RFC 2616 13.3.4 for more details (these are SHOULD/MAY clauses, so I
think we can discard them when we are dealing with dynamic data).

This patch fixes a nasty bug in the worker MPM where the
state of the worker threads was not being reported back to the
scoreboard, and eventually all the threads running in the children
would be reported as being in the "C -- closing connection" state.
This would wreak havoc on the idle_server_maintenance() routine. Since
these threads would never be counted as idle, the server would
spawn children as fast as possible.
Switch back to SIGUSR1 for graceful restarts on all platforms that
support it. This defines a symbol called AP_SIG_GRACEFUL in
ap_config_auto.h which will have the appropriate signal value. All
direct references to SIGWINCH have been replaced with AP_SIG_GRACEFUL.
On Linux 2.0, use SIGWINCH instead since SIGUSR1 is used by glibc
2.0's user-space threading library to control threads. All later
versions of Linux/glibc don't have this problem. (Not to mention the
security holes in older Linux versions which make it unsuitable for
use as a web server.) If your platform doesn't have SIGUSR1, use the
appropriate mojo in configure to define what your graceful restart
signal should be.
In theory, a configure switch could be added to allow the admin to
specify the appropriate signal that should be used. This is left
as an exercise to the reader for now.
The docs need to be updated. Since the signal is now configurable,
just saying SIGUSR1 for graceful restart isn't completely true. Also,
the apachectl functionality needs to be moved into httpd - this is
what Win32 does and it makes us consistent across platforms.
Roy issued a veto against use of SIGWINCH by default, so this should
resolve that veto.

Cleanup the worker MPM. We no longer re-use transaction
pools. This incurs less overhead than shuffling the pools
around so that they can be re-used. Remove one of the
queue's condition variables. We just redefined the API to
state that you can't try to add more stuff than you allocated
segments for.
Revamp the API that mod_dav uses to talk to back end deadprop (propdb)
providers. The old API was really based on how the FS stored properties, but
sucked for other types of providers (SQL databases, Subversion, etc). This
new code is overall much cleaner as it moves from a DBM style API to one
tuned for actual mod_dav operation; it also more flexible/clearer for future
improvements (e.g. dropping props directly to the wire rather than buffering
in memory).
This new API allows the provider to better define namespace handling during
the output of the values, how values are serialized and stored, the mapping
between elements' namespaces and the internalized namespace storage, a
clearer mechanism for naming properties (dav_prop_name), and an explicit
rollback mechanism to deal with PROPPATCH atomicity.
Updated the FS provider (fs/dbm.c) to the new API, mostly by moving code
from main/props.c. Of course, with the new semantics, some big changes in
the namespace mapping were made.
Now that we have apr_datum_t, convert some uses of dav_datum over to
apr_datum_t (the two are equivalent).
Expose some of the DAVFS' internal DBM cover functions and have the locking
code use them directly, rather than thru the vtable. That vtable will be
changing shortly, so this shift is needed.
Remove the Win32 script-processing exception from mod_cgi, and
roll build_command_line/build_argv_list into a unified, overrideable
ap_cgi_build_command optional function.
Eliminates a ton of Win32 cruft from core.c for registry parsing.
Win32 (through the default handler, and newest changes to the
apr_proc_create fn) continues to serve .bat/.exe files. This is in
preparation for adding modules/arch/win32/mod_win32 for scripts.
Please review the mod_cgi.c behavior very carefully.
Temporary hack to ensure that the split results are within a brigade
attached to the proper pool. Otherwise, ctx->b would end up associated with
the request pool, and the SOCKET bucket from the CORE_IN filter would get
cleared at request end (thus the next request would go to CORE_IN for more
data and get APR_EOF, and figured there were no more requests).
This section of code was only triggered when a request had a body. The
symptom was closing the connection (even though it should have been a
keepalive) after the response was sent.
