not even a half-baked idea:
Somebody gets the monitor hook called from the Windows MPM (i.e.,
fixes Apache on Windows to call a hook that is provided on
Unix/Linux).
General idea (mpm_winnt.c)
/* Wait for shutdown or restart events or for child death */
winnt_mpm_state = AP_MPMQ_RUNNING;
do {
rv = WaitForMultipleObjects(NUM_WAIT_HANDLES, (HANDLE *)
event_handles, FALSE, something-that-means-one-second);
if (rv == WAIT_TIMEOUT) {
ap_run_monitor(pconf);
}
} while (rv == WAIT_TIMEOUT);
(remove existing check for WAIT_TIMEOUT that considers it a fatal error)
Your application starts httpd.exe with a define like
-DMOD_FOO_MONITORED_PID=13579
and a config that loads a custom plug-in module provided by you which
implements the monitor hook that checks for when that pid goes away.
???How to make the monitor hook take down httpd? apache -k stop???
