lua-nginx-module source code layout

bharani.sub

Hi,

I know from the documentation that lua-nginx module integrates the nginx event loop (reactor) withe the coroutine of lua/luajit. This is a beautiful concept and I am trying to read the source code to appreciate it better. Though the code is very neatly named and written i need some help in figuring out where to start. Any pointers to help me figure out how coroutine and event loop is integrated is appreciated.

Thanks

Bharani

Yeah, I owe the community a good set of documentation on ngx_lua's
internals. All we have right now is just some brief discussion of the
implementation in ngx_lua's user manual:

    https://github.com/openresty/lua-nginx-module#readme

chaoslawful used to write a very high level overview for ngx_lua too:

    https://github.com/openresty/lua-nginx-module/wiki/Introduction

But it's very abstract.

For the moment, the best place to get enlightened is the source code
base. You're welcome to ask questions about specific implementation
details here. I'll try my best to answer them. But I don't have the
time to give very elaborate explanation of the whole code base right
now. Sorry.

Best regards,

Oh, forgot to mention that you may find my former presentations on
OpenResty helpful too. They usually do not talk on the C source code
level but they often have nifty architectural graphs for the key
components:
