hmm despite saying tox==3.12.1, I appear to be getting 3.0.0

[Alex Schultz (alex-schultz)]

i think it's my pyenv doing silly stuff

[Sorin Sbarnea (ssbarnea)]

Not sure in which version of tox this was added but it was long time ago, upgrade tox and try again.

The option is important as it provides real time output when run on a tty and allows capture on. on non-tty (CI).

[Sorin Sbarnea (ssbarnea)]

Alex, please try https://review.opendev.org/#/c/667056/ and tell me if it fixes the issue for you.

Newer versions of tox are even able to upgrade itself in temporary virtualenv in order to use correct version. Clearly not bumping minversion was the source of the bug.

[OpenStack Infra (hudson-openstack)]

This issue was fixed in the openstack/tripleo-common 11.1.0 release.
