Marcel Märtens 3324c08640 Fixing the DEADLOCK in handshake -> channel creation ... - this bug was initially called imbris bug, as it happened on his runners and i couldn't reproduce it locally at fist :) - When in a Handshake a seperate mpsc::Channel was created for (Cid, Frame) transport however the protocol could already catch non handshake data any more and push in into this mpsc::Channel. Then this channel got dropped and a fresh one was created for the network::Channel. These droped Frames are ofc a BUG! I tried multiple things to solve this: - dont create a new mpsc::Channel, but instead bind it to the Protocol itself and always use 1. This would work theoretically, but in bParticipant side we are using 1 mpsc::Channel<(Cid, Frame)> to handle ALL the network::channel. If now ever Protocol would have it's own, and with that every network::Channel had it's own it would no longer work out Bad Idea... - using the first method but creating the mpsc::Channel inside the scheduler instead protocol neither works, as the scheduler doesnt know the remote_pid yet - i dont want a hack to say the protocol only listen to 2 messages and then stop no matter what So i switched over to the simply method now: - Do everything like before with 2 mpsc::Channels - after the handshake. close the receiver and listen for all remaining (cid, frame) combinations - when starting the channel, reapply them to the new sender/listener combination - added tracing - switched Protocol RwLock to Mutex, as it's only ever 1 - Additionally changed the layout and introduces the c2w_frame_s and w2s_cid_frame_s name schema - Fixed a bug in scheduler which WOULD cause a DEADLOCK if handshake would fail - fixd a but in api_send_send_main, i need to store the stream_p otherwise it's immeadiatly closed and a stream_a.send() isn't guaranteed - add extra test to verify that a send message is received even if the Stream is already closed - changed OutGoing to Outgoing - fixed a bug that `metrics.tick()` was never called - removed 2 unused nightly features and added `deny_code`		2020-06-09 01:24:21 +02:00
