> sys_thread_self() returns NULL pointer if called by main process thread
> -----------------------------------------------------------------------
>
> Key: DISPATCH-1694
> URL: https://issues.apache.org/jira/browse/DISPATCH-1694
> Project: Qpid Dispatch
> Issue Type: Bug
> Components: Router Node
> Affects Versions: 1.13.0
> Reporter: Ken Giusti
> Assignee: Ken Giusti
> Priority: Major
> Fix For: 1.13.0
>
>
> Since the main process "thread" is not a pthread it does not have a
> sys_thread_t associated with it. Since the router uses the main thread as an
> I/O thread this means that an I/O thread can have a null sys_thread_self()
> value.
> While technically not _wrong_ it is unexpected; it makes comparing the return
> value of sys_thread_self() against a null/uninitialized pointer succeed.
> Proposed solution - return a dummy, non-zero value from sys_thread_id() when
> called from the main thread. Ensure this value is unique with respect to
> sys_thread_id() values returned by the "real" pthreads.
