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).

(Justin cleaned up the comment to cite RFC 2616.)

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.

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.

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.

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.

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.

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.
