> During the Liberty release the OpenStackClient (OSC) team ran into an

>
> A longer example is this, OSC has a command for listing compute flavors
> (os flavor list). zaqarclient, an OSC plugin, also implemented an `os
> flavor list` command. This caused OSC to break (it became unusable because
> it couldn't load entry points), and the user had to upgrade their
> zaqarclient, which included a renamed command (os messaging flavor list).

> In an effort to make sure this doesn't happen against, we did two things:
> 1) fixed the exception handling upon load at the cliff level, now OSC won't
> become unusable, it'll just take the last entrypoint it sees, and 2) we
> created a new gate/check job that checks for duplicate commands [2].

> I've added this job to the OpenStackClient gate (in a non-voting capacity

> - python-cueclient
> - python-designateclient
> - python-heatclient
> - python-ironicclient
> - python-ironic-inspector-client
> - python-mistralclient
> - python-saharaclient
> - python-tuskarclient
> - python-zaqarclient

Note that python-tripleoclient is also an OSC plugin.

> Regarding the eventual question about the value of a non-voting job:
> AFAICT, the new check job is working fine, it's catching valid errors and
> succeeded where it should. I'd like to make this voting eventually, but
> it's only been running in the OSC gate for about a week, and I'd like a few
> non-voting runs in the plugin projects to ensure we don't have any hiccups
> before making this a voting job.
