## Fix CloudFetchResultFetcher cancellation token chaining # Problem The CloudFetchResultFetcher.StopAsync() method could not properly cancel ongoing fetch operations because: Missing cancellation token chaining: FetchNextResultBatchAsync created timeout-only tokens using ApacheUtility.GetCancellationToken() and ignored the external cancellation token passed from StopAsync() Test reliability issues: Unit tests were failing because StopAsync() calls weren't actually cancelling background operations Resource management: Background fetch operations could continue running even after disposal # Solution Fixed cancellation token chaining in FetchNextResultBatchAsync: Replace single timeout token with proper linked cancellation tokens Combine both timeout cancellation and external cancellation using CancellationTokenSource.CreateLinkedTokenSource() Now operations respond to both user-initiated cancellation (StopAsync()) and query timeouts # Test Adding new unit test to test for timeout cancel. -- This is an automated message from the Apache Git Service.
