Andrew Stitcher commented on PROTON-2770:
-----------------------------------------
Technically the documentation does say that the only threasd safe connection
level API is proton::connection:::wake(), but it is not clear the work_queue()
accessor is not thread safe - and since it is entrely there for thread safety
it should either be thread safe or explicitly noted as not thread safe
everywhere!
> Getting the work queue with proton::link::work_queue() is not thread safe

> Key: PROTON-2770
> URL: https://issues.apache.org/jira/browse/PROTON-2770
> Project: Qpid Proton
> Issue Type: Bug
> Components: cpp-binding
> Affects Versions: proton-c-0.39.0
> Reporter: Jean-François Simoneau
> Assignee: Andrew Stitcher
> Priority: Major
>
> The accessor proton::link::work_queue() returns a reference to the
> proton::work_queue(), but making that call uses the link::container() method
> that increases the refcount on the pn_connection, making this function
> uncallable from outside of the work_queue.
> I believe the documentation should make that explicit, or the function should
> be changed to be thread safe.
