From 458089bbad9cf5bef6cf8119f23fc44e66b36ad3 Mon Sep 17 00:00:00 2001 From: Florin Coras Date: Wed, 21 Aug 2019 16:20:44 -0700 Subject: session: move ctrl messages from bapi to mq Type:refactor Moves connect, disconnect, bind, unbind and app detach to message queue from binary api. Simplifies app/vcl interaction with the session layer since all session control messages are now handled over the mq. Add/del segment messages require internal C api changes which affect all builtin applications. They'll be moved in a different patch and might not be back portable to 19.08.
