From 980764774efe55f95412555d612bc1bee39396f3 Mon Sep 17 00:00:00 2001 From: Dmitriy Ryajov Date: Sun, 2 Aug 2020 23:20:11 -0600 Subject: [PATCH] pubsub timeouts tuning (#295) * add finegrained timeouts to pubsub * use 10 millis timeout in tests * finalization * revert timeouts * use `atEof` for reads * adjust timeouts and use atEof for reads * use atEof for reads * set isEof flag * no backoff for pubsub streams * temp timer increase, make macos finalize * don't call `subscribePeer` in libp2p anymore * more traces * leak tests * lower timeouts * handle exceptions in control message * don't use `cancelAndWait` * handle exceptions in helpers * wip * don't send empty messages * check for leaks properly * don't use cancelAndWait * don't await subscribption sends * remove subscrivePeer calls from switch * trying without the hooks again --- libp2p/multistream.nim | 2 +- libp2p/muxers/mplex/lpchannel.nim | 2 +- libp2p/muxers/mplex/mplex.nim | 5 +- libp2p/protocols/pubsub/floodsub.nim | 9 ++-- libp2p/protocols/pubsub/gossipsub.nim | 27 ++++++---- libp2p/protocols/pubsub/pubsub.nim | 45 ++++------------- libp2p/protocols/pubsub/pubsubpeer.nim | 70 ++++++++++++++++++++------ libp2p/switch.nim | 46 +++++++++-------- tests/pubsub/testfloodsub.nim | 41 +++++++++++++++ tests/pubsub/testgossipsub.nim | 41 +++++++++++++++ tests/testmultistream.nim | 4 ++ 11 files changed, 205 insertions(+), 87 deletions(-) diff --git a/libp2p/multistream.nim b/libp2p/multistream.nim index 535de0c..c74a81f 100644 --- a/libp2p/multistream.nim +++ b/libp2p/multistream.nim @@ -123,7 +123,7 @@ proc handle*(m: MultistreamSelect, conn: Connection, active: bool = false) {.asy trace "handle: starting multistream handling", handshaked = active var handshaked = active try: -
