2022-08-28holy crap, it actually kinda works nowEgor Tensin
Previously, I had a stupid system where I would create a thread after every accept(), and put worker descriptors in a queue. A special "scheduler" thread would then pick them out, and give out jobs to complete. The problem was, of course, I couldn't conveniently poll job status from workers. I thought about using poll(), but that turned out to be a horribly complicated API. How do I deal with partial reads, for example? I don't honestly know. Then it hit me that I could just use the threads that handle accept()ed connections as "worker threads", which would synchronously schedule jobs and wait for them to complete. This solves every problem and removes the need for a lot of inter-thread synchronization magic. It even works now, holy crap! You can launch and terminate workers at will, and they will pick up new jobs automatically. As a side not, msg_recv_and_handle turned out to be too limiting and complicated for me, so I got rid of that, and do normal msg_recv/msg_send calls.

2022-08-26add some more codeEgor Tensin
This adds a basic "worker" program. You can now do something like ./server & ./worker & ./client ci_run URL REV and the server should pass a message to worker, after which it should clone the repository at URL, checkout REV, and try to run the CI script. It's extremely unfinished: I need to sort out the graceful shutdown, how the server manages workers, etc.
