[Feature & Proposal] Halting Log Output and Graceful Restart/Stop

[bagasme]

Description

As @zeripath mentioned in #9930, we need a way to halt log output. This may be required for using logrotate for example.

We can introduce graceful restart and stop to achieve the feature mentioned above. In graceful stop, the Gitea process isn't immediately stopped, but let the remaining requests to be processed prior to stop. Graceful restart use similar technique, instead that new requests are served using new generation of Gitea process.

@bagasme I'm also handling log rotation myself, using logrotate. (Must do so, so can feed logs into log management stack.)

The gitea container already runs s6, so log rotation would be very easy.

With s6 I would typically do:

s6-svc -1 /etc/s6/gitea/      # or -2 for SIGUSR2

Which would make s6 send signal SIGUSR1 to the app, which should force the app to release and reopen the log file (which has just been rotated).

But of course gitea doesn't currently support reopening of its log file.

Have you found a workaround in the meantime?
