and completely contained in a file (SCOREBOARD_FILE) has been
removed. This does not affect scoreboards which are *mapped* to
files using named-shared-memory at all. This implies that scoreboards
must be based, at some level, on native shared memory (mmap, shm_open,
shmget, whatever), but the code has assumed that for quite awhile
now. Having the scoreboard be *based* on a file makes no sense today.

Move ap_restart_time into the scoreboard global area so the child process
on non-forking platforms can have access to it.

create the scoreboard's shared memory segment. We now have the best of
both worlds:
if config specifies ScoreBoardFile
create name-based shared memory, errors are fatal
else /* we get to choose */
create anonymous shared memory
if ENOTIMPL
create name-based shared memory from DEFAULT_SCOREBOARD
else
errors are fatal
This gives us the flexibility to have anonymous shared memory (on platforms
that support it) as well as name-based shared memory when third-party
programs want access to our scoreboard.
The ap_scoreboard_fname static variable is now owned by the scoreboard.c
file, and no longer by the MPMs. The MPMs MUST NOT set ap_scoreboard_fname
to a default, since that will override the default creation logic and
only allow name-based segments.

The child processes use the child_init phase to reattach to the shared
memory. This makes Windows work like Unix, which should make it easier
for module authors to write portable modules.

pointer math. This is required for portable scoreboards.
vhost becomes the 'vhost name string' so it now survives ap_generation
clicks. next was apparently never used.
This patch also accounts for the changes to the apr_shm api, and gives
Win32 the magic of a shared scoreboard.
Breakage aplenty on non-win32 platforms, I suspect, but this radical
surgery, and culling of unused functions, was really, really needed.

The right solution, once required, is to wrap the FRAMING requirement
into the mmap logic so we can always ask for a n byte mmap, only to be
given a n + (pg - (n % pg)) byte region without consumer hassles.

. get the SS field in extended status output formatted correctly
(seconds since beginning of request shouldn't be a huge
negative number :) )
. use APR_OS_PID_T_FMT and pid_t where appropriate in mod_status

architectures

This is to fix a problem where the scoreboard is filled with
quiescing processes and no working processes can start, triggered by
MaxRequestsPerChild. perform_idle_server_maintenance could theoretically
cause it as well.

for ap_cleanup_scoreboard, then we have to kill that cleanup with the same
function. This also makes ap_cleanup_scoreboard a non-static function, and
makes ap_cleanup_shared_mem a static function.

Still to do:
Rename some of the function APIs. Replace all calls to reinit_scoreboard with
ap_create_scoreboard. Add back in support for scoreboard files.

basically a straight port of the 1.3 module to 2.0. The MPMs need to be
modified a bit to work with mod_status, but prefork, mpmt_pthread, and
dexter have already been changed. I will fix perchild tonight. There
is a lot of common code that can be abstracted, and there seems to be a
small bug with regard to what mpmt_pthread and dexter report as current
connections. ExtendedStatus does work again, although until the bug
mentioned above is fixed, it isn't as useful on mpmt_pthread and dexter.
Next week, I will look at allowing other modules to add data to the
STATUS page and possibly to the scoreboard itself.
