Allow cosockets, light threads, semaphores and etc in the context of init_by_lua*

Open agentzh opened this issue 8 years ago • 13 comments

It is desired to enable those Lua APIs that might yield in the context of init_by_lua*. It's particularly useful to have the ability to initiate multiple concurrent light threads to (pre)load crucial metadata from some remote services upon startup.

Under the hood, we can simply plant an event loop in the init_by_lua* handler with a configurable timeout protection (to avoid the server from taking too long to start).

+1 Hey, i'm also interested to create a light thread in init_by_lua* to use resty.redis for read locations from a redis table. This location-entities are used to generated location-files and dynamically reload the nginx.

The current workaround is to create a light thread in init_worker_by_lua* with the ngx.worker.id equals zero and to the location retrieving there.
