Joris Vink 0dda6f996f Add a form of synchronization between what worker will be accepting ... new connections and which ones will not be notified for it. Fixes the thundering herd problem, and nicely spreads out load between all the workers equally. A configuration option (workers_max_connections) is available to tweak how many connections a worker will have before giving up the accept lock. Two ways are added to this commit for access locking: - Locking via semaphores. - Locking via GCC's builtin atomic methods. The default is running with semaphores disabled (OpenBSD cannot do sem_init() with pshared set to 1, which is required). If you want to use semaphores add KORE_USE_SEMAPHORES to CFLAGS, and -lpthread to LDFLAGS in the Makefile. Other fixes: - BSD: add a timeout to kevent(). - Merge kore_worker_wait together, linux knows waitpid() as well. - Send the correct SIGQUIT signal to workers instead of SIGINT. - Fix kore_time_ms(). - Log fatal worker messages in syslog. - Refactor code even more. - Do not free our own kore_worker structure.		2013-06-26 16:37:22 +02:00
