Bug Description

A new tox release (1.7.0) appeared today depending on virtualenv 1.11.2 (which in turn bundles pip 1.5.2). Signatures of this in tests include lines in the console log like:

tox.ConfigError: ConfigError: substitution key "posargs" not found

pkg_resources.DistributionNotFound: virtualenv>=1.11.2

    Temporarily pin tox<=1.6.1

    The release of tox 1.7.0 happened today, and we're clearly not ready
    for it yet. Stop the bleeding by sticking with 1.6.1 while we try to
    sort out the issues.

After merging the above patch, downgrading tox and virtualenv on the slaves was somewhat messy since pip uninstall was not cleaning up after itsef. The downgrade was eventually successfully accomplished with:

sudo salt '*' '
    sudo pip uninstall --yes tox virtualenv
    sudo rm -rf /tmp/pip-build-* /usr/local/lib/python2.7/dist-packages/tox \
        /usr/local/lib/python2.7/dist-packages/virtualenv \
        /usr/local/bin/tox /usr/local/bin/virtualenv
    sudo pip install -U tox==1.6.1 virtualenv==1.10.1'

(Well, almost... I special-cased the precisepy3k slaves to s/pip/pip3/ and s/2.7/3.3/ but otherwise the same.)

Upstream docs ( indicate that posargs are still a thing. May need to debug this on a case by case basis :/

As a workaround for anyone running into this, install tox 1.6.x:

  $ pip install --upgrade "tox>=1.6,<1.7"

Clark Boylan (cboylan) wrote :

I have been working with the tox upstream to sort this out. Long story short is tox 1.7.0 introduced backward incompat changes to posargs parsing which means we can't just fix it without backward compatibility issues. Current suggestion from hpk is we might use a new substitution variable that gives us the behavior we want (the old behavior) so that they can preserve the new behavior with {posargs}.

I think the tox 1.7.0 behavior is a bug, though upstream doesn't seem to be convinced of that yet.

I just commented to reinforce @cboylan's point that this is a tox bug and it should be fixed.

I just hit with this bug when using tox 1.7.1. I get the following error:

This has been fixed upstream, but is slated for the 1.8.x release train so you'll need to use 1.6.x until there is a 1.8.x release of tox.

    Tox fixed the openstack breaking bug use latest

    Hurray upstream tox merged a fix for the issue that had us stuck on
    1.6.1. They have now released a new version so we can consume that fix.
    Start using latest tox again to pull that in.

    for all the details.
