manila dsvm jobs fail due to "Could not satisfy constraints for 'horizon': installation from path or url cannot be constrained to a version"

[Matt Riedemann]

Looks like this happens when installing manila-ui test requirements:

Started around 1/29. I'm not sure what's causing it.

Whatever it is it doesn't like this not having a version:

https://github.com/openstack/manila-ui/blob/master/test-requirements.txt#L5

So it's probably something in devstack or devstack-gate that's having a hard time using upper-constraints to constrain the horizon version that's installed from git.

Problem in new PIP version - 8.0.2 It has changed logic about getting package versions

[Valeriy Ponomaryov (vponomaryov)]

And PIP of 8.* version started to be used after following devstack commit: https://review.openstack.org/#/c/271985/

that was merged on Jan 29 9:06 PM and allowed to use 8.* PIP versions

None of all other projects fail with such error, because Mainla project is the only who installs its "UI" subproject in its devstack installation.

    Fix Devstack and Manila-ui interaction

    Devstack always installs test-requirements, but we do not expect it for
    Manila UI project. Moreover, such installation started failing with
    PIP versions 8.x
    Change that triggered bug is Devstack change at [1].

This issue was fixed in the openstack/manila 2.0.0.0b3 development milestone.
