PID File is supposed to be deleted on heiko stop. about goheiko

[MadhavJivrajani]

imo the reason that the PID files don't get deleted is that in the code, context.Release() is defered, and defer isn't run if signals like SIGTERM and SIGINT are sent to the process because the process itself is basically stopped. You can try running this snippet and sending different signals to it.

This behaviour can be changed by adding some form of signal handling, like here. This works pretty well.

Ah that explains it. The example helped me see it in action, the defer statement isn't run on any of SIGINT, SIGHUP or SIGTERM. Thanks for that!

We had explored this before, but we weren't sure of how to pass the flags from cobra/viper. go-daemon seems to use the flag package along with their own interface for specific flags. Do you know of a way to convert viper flags to the flags required by go-daemon?

My initial idea was to pass a pointer to daemon.BoolFlag using the value from viper, but that seems like a hack.
