nginx -t with many worker_processes/reuseport is expensive — at Version 1

Description (last modified by bartebor@…)

nginx -t forks worker_processes worker processes just like normal nginx. With reuseport in listen directive in use each of the workers create separate socket. On modern multicore machine (assuming i.e. worker_processes auto;) this creates a lot of sockets which are not of much value. Large configurations take a lot longer to test.

I think we could assume in testing that configuration has worker_processes 1;. Is this problematic in any way?

We can't use -g option to override configured value, because nginx complains about duplicated directive.
