Add various flags to the HgProxy daemons
Summary:
- Add flags to exit after an idle time or client count.
- Add flags to control daemonization.
- Add flags to control output.
- Add flags to skip the "hello" frame of the protocol.
- Make the client launch a server if one does not exist.
The one-time overhead to launch a server and run a command through it looks to be ~130% of the overhead to run the command directly with "hg", so even if we never run a second command we're not paying too much.
The incremental overhead to run subsequent command appears to be less than 3% of the overhead to run the command directly with "hg" (and maybe less than 1%, I'm not sure how long the computation part of a command like 'hg log' "actually" takes).
The overhead to launch a PHP client, connect to an existing server, run a command, and then print it and exit is roughly 50% of the overhead to run the command directly with "hg". So theoretically a user can achieve an amortized 2x performance increase for all 'hg' commands by aliasing 'hg' to the PHP client in their shell.
Test Plan:
- Ran servers with idle and client count limits, let them idle and/or hit their connection limits, saw them exit.
- Ran foreground and background servers.
- Ran a daemon server with redirected stdout/stderr. Verified logs appeared.
- Ran with --quiet.
- Ran clients and servers with and without --skip-hello, things work if they agree and break if they disagree. The throughput gain on this is fairly small (maybe 5%?) but it seems simple enough to keep for the moment.
- Ran serverless clients and verified that servers launched the first time, were available subsequently, and relaunched after 15 seconds idle.
