-------------------------------------
Assignee: Andrew Stitcher
> user-defined signals can cause process terminate
> ------------------------------------------------
>
> Key: QPID-2388
> URL: https://issues.apache.org/jira/browse/QPID-2388
> Project: Qpid
> Issue Type: Bug
> Components: C++ Client
> Affects Versions: 0.5
> Environment: Linux
> Reporter: Azim Fatehi
> Assignee: Andrew Stitcher
>
> I have an application which uses some user-defined signals for process
> control. When trying to bind qpid in to this application I've found that the
> client library spawns an i/o thread which ignores signal masks that the
> process has defined before making any calls to qpid. The i/o thread changes
> it's own signal mask to sigemptyset and is catching signals intended for
> another thread in my process which has called sigtimedwait(). The default
> action for user defined signals is process terminate, so the process is
> subsequently dying.
> I've made the following change to EpollPoller.cpp to work around the problem
> within my environment:
> $ diff -w EpollPoller.cpp EpollPoller-fixed.cpp
> 248c248
> < ::sigemptyset(&sigMask);
> ---
> > ::sigfillset(&sigMask);
