[devel at bb.net] Request for more buildbot testing resources between Py3 and Py2

[Pierre Tardy]

Hi Craig,

We already talked about this during the weekly meeting.
This does not make much sense to use nine.buildbot.net to test worker
protocol interop, as it uses buildbot travis, and does not use all the
remote commands that are required to be tested. Also nine.bb.net uses
Hyper, which adds another level of complexity, and we can't have the
stability of this setup slow down other buildbot developement (npm
instabilities are already painful enough)

Your dogfooding proposal is better than nothing, but still requires a lot
of work, and is hard to reproduce if somebody breaks something.

End to end tests are easier, and more controllable, reproducible, etc.

Vladimir Rutsky started one here:
https://github.com/buildbot/buildbot/pull/2136
Please feel free to finish his work.

Another option I think is a bit better is to change
https://github.com/buildbot/buildbot/blob/master/master/buildbot/test/util/integration.py#L131

So that it does not create a worker inside the master's virtualenv, but to
create a worker in another virtualenv, with the option to use another
python.
Using that method, will allow us to leverage all the integration tests that
we already have, and not to have to create more in Vladimir's framework.

Pierre
