From 645d8dd2c29648b69189bb15acc6775c41707bb4 Mon Sep 17 00:00:00 2001 From: Brian Botha Date: Fri, 5 May 2023 17:24:08 +1000 Subject: [PATCH] fix: fixed bug with stream clean up and added concurrency tests * using a stop-gap measure where we add and remove data to the finish frame message. * Likely there is a bug in the `quiche` code where this packet is not being sent due to it being a 0-length message. It was fixed before in their code, but they may have missed an edge case where a large volume of data is being processed. * Fixed race condition with stream pulling data throwing error and cleaning up after stream completes. Somehow despite the code having no awaits, the readable stream was getting pulled and errored out the stream before cleaning up after the finish frame. * Added tests for concurrent servers and clients. * Cleaned up logging for streams. * Related #14 [ci skip] --- src/QUICConnection.ts | 48 ++-- src/QUICServer.ts | 3 +- src/QUICStream.ts | 175 ++++++------ tests/QUICClient.test.ts | 11 +- tests/QUICSocket.test.ts | 2 +- tests/QUICStream.test.ts | 63 +++-- tests/concurrency.test.ts | 582 ++++++++++++++++++++++++++++++++++++++ tests/utils.ts | 65 ++++- 8 files changed, 804 insertions(+), 145 deletions(-) create mode 100644 tests/concurrency.test.ts diff --git a/src/QUICConnection.ts b/src/QUICConnection.ts index 52b41627..526ca967 100644 --- a/src/QUICConnection.ts +++ b/src/QUICConnection.ts @@ -46,7 +46,6 @@ class QUICConnection extends EventTarget { protected codeToReason: StreamCodeToReason;
