When I did it I put the impl in child.c where the event is a static global

I added something like this to our distribution in IBM to address a
hairy problem with our security library.
Each MPM already has a way to terminate the process due to
MaxRequestsPerChild, e.g. check_infinite_requests() in worker and
event or the block like this in winnt:
/* Have we hit MaxConnectionsPerChild connections? */
if (ap_max_requests_per_child) {
requests_this_child++;
if (requests_this_child > ap_max_requests_per_child) {
SetEvent(max_requests_per_child_event);
}
}
I don't see how I can get the right event: max_requests_per_child_event.
May be I need to remember more on windows :-(
If you look at the "mpm_get_name" hook, this gives a pattern where
each MPM can provide the impl itself. Then there would just be some
non-static thing in e.g. core.c that does the ap_run_foo part.
Something like ap_run_child_stopping(r->pool, 1); seems to do the job
for event, prefork and worker... I am stuck for windows.

I added something like this to our distribution in IBM to address a
hairy problem with our security library.
Each MPM already has a way to terminate the process due to
MaxRequestsPerChild, e.g. check_infinite_requests() in worker and
event or the block like this in winnt:
/* Have we hit MaxConnectionsPerChild connections? */
if (ap_max_requests_per_child) {
requests_this_child++;
if (requests_this_child > ap_max_requests_per_child) {
SetEvent(max_requests_per_child_event);
}
}
If you look at the "mpm_get_name" hook, this gives a pattern where
each MPM can provide the impl itself. Then there would just be some
non-static thing in e.g. core.c that does the ap_run_foo part.
graceful stop of child process in a module
Hi, I am try to gracefully stop a child process instead using ap_assert(0), is there a "clean way" to do that? -- Cheers Jean-Frederic
