[Python-modules-team] Bug#950738: python3-urllib3: Requires python3-six > 1.10.0-4

[Nik A. Melchior]

Package: python3-urllib3
Version: 1.25.6-5
Severity: wishlist

Dear Maintainer,

I'm not sure how or when Debian considers versioned dependencies on
packages, but I ran into a failure due to patchworked upgrades.  I hope
to save someone else the time it took me to debug the issue.

The communication between ycmd and the vim-youcompleteme plugin on my
system was failing due to an exception being thrown out of urllib3.
I had the latest urllib3, but my python3-six module was outdated
(1.10.0-4 was installed).  Eventually, I determined that it was
attempting to call six.ensure_text(), which didn't exist in my installed
version.  Updating to the latest version (1.14.0-2) of six fixed the
problem.

Debugging was difficult beecause the failing urllib3 caught the
AttributeError resulting from the missing function, then rethrew
a different exception.

Thanks,

-- Nik Melchior
