C++: client request memory leak on windows ------------------------------------------
Key: QPID-1952 URL: https://issues.apache.org/jira/browse/QPID-1952 Project: Qpid Issue Type: Bug Components: C++ Client Affects Versions: 0.5 Environment: Windows XP Pro w/SP3 Reporter: David Rennalls I'm experiencing a memory leak when using the client library on Windows (0.5 release) when sending a single request. From what debugging I've done so far it looks like the The AsynchIO object used by the TCPConnector is not being deleted. When the connection is being closed aio->queueForDeletion() is called from TCPConnector::closeInternal().. However in AsynchIO::queueForDeletion() aio.opsInProgress > 0 so the 'delete this' branch is not done. There are no more queueForDeletion() calls made on the aio object (after opsInProgress is 0) and so it never gets deleted. The ConnectionImpl object involved is not cleaned up either, the shared_ptr to it has a non-zero ref count but I'm guessing it's related to the AsynchIO object not being cleaned up. There used to be some code in AsynchIO::completion() that seems like it would do the necessary delete (see below). It was removed with code changes in https://issues.apache.org/jira/browse/QPID-1550 because 'It fixed a memory corruption on the broker side by deleting too early' (from Steve H.) - // Lock released; ok to delete if all is done. - if (opsInProgress == 0 && queuedDelete) - delete this; -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online. --------------------------------------------------------------------- Apache Qpid - AMQP Messaging Implementation Project: http://qpid.apache.org Use/Interact: mailto:dev-subscr...@qpid.apache.org
