[ ] implements UDP shutdown correctly, the one created in connect! [ ] unify logging [ ] fill metrics [ ] fix dropping stream before last messages can be handled bug [ ] add documentation [ ] add benchmarks [ ] remove async_serde???

Whoever we need to keep the order of frames, (at least for controlframes) so serialising in threads would be quite complicated. Also serialisation is quite fast, about 1 Gbit/s such speed is enough for messaging, it's more important to serve parallel streams better. Thats why i am removing async serde coding for now - frames are no longer serialized by serde, by byte by byte manually, increadible speed upgrade - more metrics - switch channel_creator into for_each_concurrent - removing some pool.spwan_ok() as they dont allow me to use self - reduce features needed --- Cargo.lock | 38 -- network/Cargo.lock | 15 - network/Cargo.toml | 13 +-

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` --- network/examples/async_recv/src/main.rs | 2 +- network/src/api.rs | 61 ++------ network/src/channel.rs | 110 ++++++++------ network/src/lib.rs | 3 +- network/src/message.rs | 13 +- network/src/participant.rs | 92 ++++++----- network/src/prios.rs | 22 +-- network/src/protocols.rs | 194 +++++++++--------------- network/src/scheduler.rs | 61 +++++--- network/tests/closing.rs | 30 ++++ network/tests/integration.rs | 33 ++-- server/src/lib.rs | 5 +- 12 files changed, 320 insertions(+), 306 deletions(-) diff --git a/network/examples/async_recv/src/main.rs b/network/examples/async_recv/src/main.rs index 5da8627fc0..2c547e35c5 100644 --- a/network/examples/async_recv/src/main.rs +++ b/network/examples/async_recv/src/main.rs @@ -21,7 +21,7 @@ enum Msg { Pong(u64), } -/// This utility checks if async functionatily of veloren-network works +/// This utility checks if async functionality of veloren-network works /// correctly and outputs it at the end fn main() { let matches = App::new("Veloren Async Prove Utility") diff --git a/network/src/api.rs b/network/src/api.rs index cbe13541fa..a07a7c86f6 100644 --- a/network/src/api.rs +++ b/network/src/api.rs @@ -3,7 +3,7 @@ //! //!

From 2e3d5f87db8d88dd47668f7b74c6c022190d4bda Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Marcel=20M=C3=A4rtens?= Date: Mon, 8 Jun 2020 11:47:39 +0200 Subject: [PATCH 32/32] StreamError::Deserialize is now triggered when `recv` fails because of wrong type - added PartialEq to StreamError for test purposes (only yet!) - removed async_recv example as it's no longer for any use. It was created before the COMPLETE REWRITE in order to verify that my own async interface on top of mio works. However it's now guaranteed by async-std and futures. no need for a special test - remove uvth from dependencies and replace it with a `FnOnce` - fix ALL clippy (network) lints - basic fix for a channel drop scenario: TODO: this needs some further fixes up to know only destruction of participant by api was covered correctly. we had an issue when the underlying channels got dropped. So now we have a participant without channels. We need to buffer the requests and try to reopen a channel ASAP! If no channel could be reopened we need to close the Participant, while a) leaving the BParticipant in takt, knowing that it only waits for a propper close by scheduler b) close the BParticipant gracefully. Notifying the scheduler to remove its stuff (either scheduler schould detect a stopped BParticipant or BParticipant will send Scheduler it's own destruction, and then Scheduler just does the same like when API forces a close) Keep the Participant alive and wait for the api to acces BParticipant to notice it's closed and then wait for a disconnect which isn't doing anything as it was already cleaned up in the background --- network/Cargo.toml | 7 +- network/examples/async_recv/Cargo.lock | 978 --------------------- network/examples/async_recv/Cargo.toml | 20 -
