Error running manage.py compress after https://review.openstack.org/#/c/399771/

[Alfredo Moralejo]

After https://review.openstack.org/#/c/399771/, we are getting following error when running "python manage.py compress":

CommandError: An error occurred during rendering /tmp/horizon/openstack_dashboard/templates/_stylesheets.html: Couldn't find anything to import: ../../mixins

and exits.

Note that this issue is making horizon packaging to fail.

I was missing running collectstatic before compress. After doing it, it worked fine.

I'm sorry but I confirm this on stable/newton :

(.venv)yves@paradox ~/openstack/pure_horizon/horizon $ python manage.py collectstatic --noinput && python manage.py compress --force

You need a clean install (no static folder) to reproduce the issue.

[Rob Cresswell (robcresswell-deactivatedaccount)]

You can (and should) use manage.py collactstatic -c to clear the folder first before collecting again. This might be broken because of a new version of roboto which changed paths; you should use the version listed in upper-constraints.

[Rob Cresswell (robcresswell-deactivatedaccount)]

collectstatic*

[Yves-Gwenael Bourhis (yves-gwenael-bourhis)]

The error does not occur on the master branch. Only stable/newton is affected

[Yves-Gwenael Bourhis (yves-gwenael-bourhis)]

Commands tu reproduce:

    git checkout stable/newton
    git pull
    rm -rf .venv
    rm -rf static # PLEASE DO THIS TO REPRODUCE If you don't you do not reproduce the issue.
    find . -iname '*.pyc' -delete
    virtualenv .venv
    . .venv/bin/activate
    easy_install -U pip # required on ubuntu 14.04
   pip install -Ur test-requirements.txt && pip install -Ur requirements.txt
   ./run_tests.sh --compilemessages
   python manage.py collectstatic --noinput # <- SEE here I DO run the command
   python manage.py compress --force

On my first post: https://bugs.launchpad.net/horizon/+bug/1643689/comments/2 you can clearly see that I did run collectstatic before.

[Yves-Gwenael Bourhis (yves-gwenael-bourhis)]

Some patch from master needs to be backported to newton because master is not affected

[Alfredo Moralejo (amoralej)]

What version of XStatic-roboto-fontface are you getting in your env?

[Yves-Gwenael Bourhis (yves-gwenael-bourhis)]

Hi Alfredo.

On stable/newton and master I both get : XStatic-roboto-fontface==0.5.0.0

Note : I did a "pip install -Ur test-requirements.txt && pip install -Ur requirements.txt" after switching branch and before looking at the XStatic-roboto-fontface version.
The requirements of master and stable/newton seem to pull the same version.

But I have the error only on newton. Weird...
My pip installed pip packages are in attachment and the only difference between newton and master is:

(.venv)yves@paradox ~/openstack/pure_horizon/horizon $ diff requirements_newton.txt requirements_master.txt
120c120
< Sphinx==1.2.3
---
> Sphinx==1.3.6

[Alfredo Moralejo (amoralej)]

Note that the newest supported version for newton is 0.4.3.2 as defined in upper-constraints for stable/newton: https://github.com/openstack/requirements/blob/stable/newton/upper-constraints.txt#L58

I think using that version will fix the issue.

Version 0.5.0.0 is only compatible with recent version in master.

[Yves-Gwenael Bourhis (yves-gwenael-bourhis)]

Thanks Alfredo, so it's well a bug from newton in requirments.txt in stable newton:

https://github.com/openstack/horizon/blob/stable/newton/requirements.txt#L62

^ this pulls the latest Version (Currently 0.5.0.0) since XStatic-roboto-fontface version 0.5.0.0 satisfies the XStatic-roboto-fontface>=0.4.3.2 condition.

[Yves-Gwenael Bourhis (yves-gwenael-bourhis)]

I checked and confirm thant on stable/newton after a "pip install -U "XStatic-roboto-fontface===0.4.3.2" the issue is solved.

Hello Yves-Gwenael Bourhis:
   My environment XStatic-roboto-fontface version is 0.4.3.2, but there are still this bug, my environment is Ubuntu 16.04 when run devstack when install Horizon, I had to comment out these lines of code(https://github.com/openstack/horizon/blob/master/openstack_dashboard/settings.py#L292-L295).

[Rob Cresswell (robcresswell-deactivatedaccount)]

This doesn't appear with the constrained version of our requirements, so marking Wont Fix.
