Hey,
I'm debugging a problem with a crash in MHD_select_thread. We had
MHD_start_daemon_va fail while creating worker threads with the following
error: "file descriptor for worker control pipe exceeds maximum value". We
know what caused this error and are fixing it. But the problem was that a
MHD_select_thread worker thread was left running in the background after
MHD_start_daemon_va returned failure. I think the problem is from this
code in the thread_failed case in daemon.c:
/* Shutdown worker threads we've already created. Pretend
as though we had fully initialized our daemon, but
with a smaller number of threads than had been
requested. */
daemon->worker_pool_size = i - 1;
MHD_stop_daemon (daemon);
return NULL;
>From the code, it looks like "i" is actually the number of threads that
were successfully created, so the "i - 1" in this code will leave an extra
thread hanging since MHD_stop_daemon will clean up one less thread than it
should. I'll probably try to work up a test to verify removing the "- 1"
is correct, but that could take me some time so I wanted to make sure I
wasn't missing something obvious before heading down that path.
