I see pyngus on pypi, and you mention in the “Request to include AMQP 1.0 support in Juno-3” thread that proton is being packaged in EPEL and work is ongoing for Debian. Is that done (it has only been a few days, I know)? Hi Doug, Yes, AMQP 1.0 tech is pretty new, so the availability of the packages is the sticking point. That said, there are two different dependencies to consider: oslo.messaging dependencies, and AMQP 1.0 support in the brokers. For oslo.messaging, the dependency is on the Proton C developer libraries. This library is currently available on EPEL for centos6+ and fedora. It is not available in the Ubuntu repos yet - though they have recently been accepted to Debian sid. For developers, the QPID project maintains a PPA that can be used to get the packages on Debian/Ubuntu (though this is not acceptable for openstack CI support). The python bindings that interface with this library are available on pypi (see the amqp1-requirements.txt in the driver patch). This seems sufficient for now. We won’t list the dependencies directly for oslo.messaging, so the libs don’t necessarily need to be available as packages until we bring it out of “experimental” status (and that move will be blocked based on availability of the libs). Qpid upstream has been shipping with 1.0 support for awhile now, but unfortunately the popular distros don't have the latest Qpid brokers available. Qpid with AMQP 1.0 support is available via EPEL for centos7 and fedora. RedHat deprecated Qpid on rhel6, so now centos6 is stuck with an old version of qpid since we can't override base packages in EPEL. Same deal with Debian/Ubuntu, though the QPID PPA should have the latest packages (I'll have to follow up on that). I would like to avoid having that packaging work be a blocker, so if we do include the driver, what do you think is the best way to convey the instructions for installing those packages? I know you’ve done some work recently on documenting the experimental status, did that include installation tips? Not at present, but that's what I'm working on at the moment. I'll definitely call out the installation dependencies and configuration settings necessary for folks to get the driver up and running with a minimum of pain. I assume I'll have to update at least: The wiki: https://wiki.openstack.org/wiki/Oslo/Messaging The user manuals: http://docs.openstack.org/icehouse/config-reference/content/configuring-rpc.html I can also add a README to the protocols/amqp directory, if that makes sense. Sounds good. Those updates should allow deployers who want to use the driver to find out what else they need to install, and how to get it for their platforms.
