Running code in nginx's master process

Server NGINX
1

Is it possible to have a module run code in nginx’s master process, i.e.
not
in a worker process?
I know init_master is just a stub for now. Are there any chances this
gets
implemented in the near future?

Thanks in advance,
Marcelo.

I wouldn’t recommend running a code in master process, but if you
have to for some reason, you may try using init_module callback.

It seems like the init_module callback is not executed in nginx’s master
process. At least, I’ve printed a call to getpid() and the pid returned
was
that of a process that wasn’t running, which makes me think it is
executed
in a process that forks the master process itself.

Yes, the init_module callback is called after configuration parsing,
and on initial startup this happens before demonization, hence
there is no master process yet. On reconfiguration it’s executed
in the master process itself.
