Pull Request Overview
This PR adds comprehensive leak detection infrastructure for the Azure Cosmos SDK, enabling detection of both Cosmos client leaks and Netty resource leaks during testing. The implementation includes a new stack trace utility, client lifecycle tracking, custom Netty leak detection, and integration with TestNG test infrastructure.
Key Changes:
- Added
StackTraceUtilfor capturing and formatting stack traces to aid in leak diagnosis - Implemented client leak tracking in
RxDocumentClientImplusing a thread-safe map synchronized withstaticLock - Created custom
CosmosNettyLeakDetectorFactoryto detect Netty ByteBuf leaks with detailed logging
