taskflow 0.6.1 has uncapped networkx which breaks cinder py26 unit tests in juno

[Matt Riedemann]

taskflow 0.6.1 is pulled into stable/juno jobs:

http://logs.openstack.org/periodic-stable/periodic-cinder-python26-juno/1aa09f8/console.html#_2015-08-12_06_15_01_769

It has uncapped networkx:

https://github.com/openstack/taskflow/blob/0.6.1/requirements-py2.txt#L17

Latest networkx dropped py26 support:

https://github.com/networkx/networkx/pull/1192

So we need a stable/juno branch for taskflow, cap the requirements per stable/juno g-r and release that as taskflow 0.6.2 to unwedge cinder py26 in the stable/juno gate.

[Doug Hellmann (doug-hellmann)]

The taskflow requirement in stable/juno is capped at 0.7, so we should be able to create a stable/juno branch from 0.6.1, update the networkx requirement, and then release 0.6.2.

[Joshua Harlow (harlowja)]

Just checking in, I think making branch stable/juno from 0.6.1 is fine, then capping networkx is fine there. Let me know if u guys need any help doing that (pretty sure the oslo team can make that branch without me, but if needed I'll check in soonish).

[Matt Riedemann (mriedem)]

Doug created the branch, I'll work on the rest.

    Update from global requirements

    stable/juno was just created for taskflow from the 0.6.1 tag so that we
    can cap networkx (and other requirements) for taskflow in Juno. This is
    needed to unblock the gate-cinder-python26 job in Juno which uses
    taskflow and with uncapped networkx, pulls in 1.10 which dropped py26
    support.

    As the first change to stable/juno for taskflow, this also updates
    the .gitreview file.
