Please unblock package python-virtualenv
python-virtualenv (20.4.0+ds-2) unstable; urgency=medium
.
* Patch: Fix --upgrade-embed-wheels.
* Replace the pkg_resources addition part of
debian_update_for_available_wheels.patch with include-pkg_resources.patch
which will only include pkg_resources when using Debian's bundled
setuptools wheel. (Closes: #976796)
[ Reason ]
The --upgrade-embed-wheels option was not working at all, it would
crash, if you attempted to use it. This was fixed upstream later in
20.4.x, so cherry-picked that trivial patch.
Relatedly, we got to the bottom of #976796, which was caused by upgraded
wheels, which would include pkg_resources in the setuptools wheel
(Debian splits it into its own binary package). This could cause a race
on unpacking, crashing.
[ Impact ]
If a user has an upgraded virtualenv wheel cache, then virtualenv
becomes unreliable, due to a race (two threads unpacking the target
files).
[ Tests ]
Manually tested 4 variants:
--seeder pip before and after --upgrade-embed-wheels
--seeder app-data and after --upgrade-embed-wheels
Autopkgtests verify that the basic functionality is unaffected.
[ Risks ]
The changes are relatively straightforward, and should improve
robustness.
[ Checklist ]
[x] all changes are documented in the d/changelog
[x] I reviewed all changes and I approve them
[x] attach debdiff against the package in testing
