django-openstack-auth 1.1.8+ breaks stable/icehouse devstack

[Ryan Hsu]

Global requirements currently has no cap for the django-openstack-auth dependency, which is used for Horizon and there are a few problems with the latest releases with regards to stable/icehouse:

1. version 1.1.8 breaks unit tests as per bug #1413876 [1]
2. version 1.1.9 adds[2] a requirement for oslo.config>=1.6.0 but stable/icehouse projects require oslo.config<1.5.0 (for example see nova [3])

This can be fixed by adding a django-openstack-auth<1.1.8 constraint to horizon and global requirements. The fix will resolve the following error message seen during stacking:

Dependencies in requirements.txt do not seem to be used in stable/icehouse gate jobs, recent pip freeze in stable/icehouse shows:
...
 oslo.config==1.6.0 # git sha 99e530e
 django-openstack-auth==1.1.9 # git sha 2079383

Alan is correct, I just looked at a recent stable/icehouse Horizon patch (#149621) that passed gate but the devstack log showed multiple occurrences of oslo.config getting uninstalled with the 1.6.0. You can see these if you open up the devstack log [1] for that run and search "uninstalling oslo.config".
