From 1d4726c8bbdbe1877a62c1b2a5349db5d0159a6b Mon Sep 17 00:00:00 2001 From: Zang MingJie Date: Thu, 22 Apr 2021 06:30:00 +0800 Subject: [PATCH] Release all exchange contexts when shutting down the exchange manager (#5692) * Release all exchange contexts when shutting down the exchange manager There is also an on-going work of replacing raw pointer of ExchangeContext with a unique_ptr like handle. MessageCounter tests are broken due to incompleted implementation, I'll fix the test in the following up message counter PR. * Force close ExchangeContexts when shutting down the ExchangeManager * Remove useless comment * Crash when ExchangeContext is leaked --- src/messaging/ExchangeMgr.cpp | 6 ++++++ src/messaging/tests/BUILD.gn | 2 -- src/messaging/tests/TestExchangeMgr.cpp | 8 +++++++- src/messaging/tests/TestMessageCounterSyncMgr.cpp | 2 ++ src/messaging/tests/TestReliableMessageProtocol.cpp | 9 +++++++++ 5 files changed, 24 insertions(+), 3 deletions(-) diff --git a/src/messaging/ExchangeMgr.cpp b/src/messaging/ExchangeMgr.cpp index b15bbe567ec7db..8ff2753685f1a0 100644 --- a/src/messaging/ExchangeMgr.cpp +++ b/src/messaging/ExchangeMgr.cpp @@ -102,6 +102,12 @@ CHIP_ERROR ExchangeManager::Shutdown() mMessageCounterSyncMgr.Shutdown();
