----------------------------
Resolution: Not A Problem
> Memory leak when creating endpoint objects with a handler
> ---------------------------------------------------------
>
> Key: PROTON-1691
> URL: https://issues.apache.org/jira/browse/PROTON-1691
> Project: Qpid Proton
> Issue Type: Bug
> Components: proton-c
> Affects Versions: proton-c-0.18.1
> Environment: Reproduced on Windows but the code is not platform
> specific.
> Reporter: Xin Chen
> Assignee: Cliff Jansen
>
> Using the Python binding, one can provide a handler when creating an Endpoint
> object (Connection/Session/Link). This handler object is set in the record
> context. In pn_###_finalize methods, the context is not cleared by calling
> pn_record_clear. This results in a _cadapter object leaking in Python process
> without any references. The fix is simply to call pn_record_clear before
> freeing the context. For example, in pn_link_finalize (line 1121 in engine.c),
> + pn_record_clear(link->context);
> pn_free(link->context);
> With this fix the memory does not grow anymore with repeated link
> creation/closing. I only use a handler in link endpoint but I think this is
> needed for connection and session as well.
