Support

In case anyone else runs into this:

Today qpid-dispatch-router was updated from version 1.1.0 to 1.2.0 in epel7. After updating the qdrouterd service would not start up:

systemd[1]: Started Qpid Dispatch router daemon.
systemd[1]: Starting Qpid Dispatch router daemon...

systemd[1]: qdrouterd.service: main process exited, code=exited, status=1/FAILURE

I changed the relevant part in the mentioned file dispatch.py to the proposed change for version 1.3.0:

which fixed the problem.

Man, I just hit this bug.

After building out a brand new platform, and first set of patches to be applied and dang if it didn’t break qdrouter. Talk about ticked off. EPEL registered upstream too. #awesome

Lucky enough, I sync EPEL and was able to downgrade qpid-dispatch-router.

yum downgrade http://host.example.com/pulp/repos/company/Library/custom/EPEL/EPEL_for_Red_Hat_Enterprise_Linux_7/Packages/q/qpid-dispatch-router-1.1.0-1.el7.x86_64.rpm
—> Package qpid-dispatch-router.x86_64 0:1.1.0-1.el7 will be a downgrade
—> Package qpid-dispatch-router.x86_64 0:1.2.0-1.el7 will be erased

This of course is another option to what ppascher has posted.

I can’t find a bugzilla for this. Has anyone filed one for EPEL?

I meant to reply back here. The qpid team is aware of and has a proposed fix available. You can find it in the EPEL testing repository:

https://dl.fedoraproject.org/pub/epel/testing/7/x86_64/Packages/q/

This is also in Bodhi if anyone who tests it would give approval if working for them to get it pushed out to users faster:

Another workaround is to remove the python2-future package on the system if you don’t have any packages installed which depend on it, and then restart qdrouterd.
