David Rennalls updated QPID-1952:
---------------------------------
Attachment: Connector_memory_leak.patch
This fixed the leak for me. I'm only using the client library and don't know if
this leak exists in the broker's usage.
> 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
> Attachments: Connector_memory_leak.patch, Main2.cpp
>
>
> 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;
