[rabbitmq-discuss] Hacking on RabbitMQ?

I wrote a couple of docs some months ago and you can find them here:

Feel free to fix them/expand them but I'm not sure if they will help much.

Regarding the msg_store and the msg_index the modules there have a lot of
docs in the source code itself.

Then take a look at the .hrl files, specially those that define Erlang
behaviours… those have a lot of docs on what each function should
implement. I always open the behaviour definitions and then grep for
modules implementing them and start from there.

Then on the rabbit_types.erl you can get a lot of insights since you can
see what a "binding_destination" is for example. You can see what the
record structures are and so on.

Read the module proper/quickcheck specs. Those can give you some info about
the expected behavior.

For exchanges I would just read other plugin exchanges. Notably those
written by Matthew like the consistent hashing exchange. I think the
implementation of the topic exchange is quite interesting too.

Regarding Erlang/OTP itself keep in mind that RabbitMQ uses its of
gen_server2 module. There might be other custom modules too that improve on
OTP itself.

I hope this helps,
