2105	thread_pools with variable $server_name	Carlos		"The context:

{{{
thread_pool $server_name threads=12;

http {
    server {
        aio threads=$server_name;
    }
}
}}}


This setup produces no errors at config test `nginx -t` but HTTP produces `Error 500` and at `error.log` because `thread_pool` is not found.

`thread pool ""example.com"" not found, server: example.com, request: ""GET / HTTP/1.1""`

It should either be allowed, or produce an an error at config test like `nginx.conf: $server_name is not allowed here`."	defect	closed	minor		nginx-core	1.19.x	wontfix			Linux nginx1 5.4.0-54-generic #60-Ubuntu SMP Fri Nov 6 10:37:59 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux	"nginx version: nginx/1.19.5
