* use __WNOTHREAD w/ waitpidEgor Tensin2023-06-30
| | | | | | | | | | I learned about this flag on my previous job; basically, it should be enabled by default IMO, so that the thread doesn't receive signals from other threads' children. Here, it doesn't matter too much, since we're waiting for a specific child. However, if we were to use waitpid(-1, ...), it would be essential to use this flag. Still, even here, it's good to have this on.

* use signalfd to stop on SIGTERMEgor Tensin2023-06-13
| | | | | | | | | | | | | | | | | | Is this an overkill? I don't know. The thing is, correctly intercepting SIGTERM (also SIGINT, etc.) is incredibly tricky. For example, before this commit, my I/O loops in server.c and worker.c were inherently racy. This was immediately obvious if you tried to run the tests. The tests (especially the Valgrind flavour) would run a worker, wait until it prints a "Waiting for a new command" line, and try to kill it using SIGTERM. The problem is, the global_stop_flag check could have already been executed by the worker, and it would hang forever in recv(). The solution seems to be to use signalfd and select()/poll(). I've never used either before, but it seems to work well enough - at least the very same tests pass and don't hang now.

| | | | | | | | Remember, this is always a mistake: ptr = realloc(ptr, size); You still need to free() the original ptr if realloc fails.

* rework server-worker communicationEgor Tensin2023-05-15
| | | | | | | | | | | | | | | | | | OK, this is a major rework. * tcp_server: connection threads are not detached anymore, the caller has to clean them up. This was done so that the server can clean up the threads cleanly. * run_queue: simple refactoring, run_queue_entry is called just run now. * server: worker threads are now killed when a run is assigned to a worker. * worker: the connection to server is no longer persistent. A worker sends "new-worker", waits for a task, closes the connection, and when it's done, sends the "complete" message and waits for a new task. This is supposed to improve resilience, since the worker-server connections don't have to be maintained while the worker is doing a CI run.
