[Python-apps-team] Bug#947551: prospector: please, tighten the dependency of prospector on python3-pep8-naming

[Rogério Brito]

Package: prospector
Version: 1.1.7-2
Severity: normal

Hi.

After a few upgrades of packages that prospector depends on, it stopped
working due to a version of python3-pep8-naming that is "too new" to satisfy
its dependencies (or, in other words, the dependency of the package is not tight
enough as what the script needs at runtime):

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
/tmp$ prospector --help
Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/pkg_resources/__init__.py", line 583, in _build_master
    ws.require(__requires__)
  File "/usr/lib/python3/dist-packages/pkg_resources/__init__.py", line 900, in require
    needed = self.resolve(parse_requirements(requirements))
  File "/usr/lib/python3/dist-packages/pkg_resources/__init__.py", line 791, in resolve
    raise VersionConflict(dist, req).with_context(dependent_req)
pkg_resources.ContextualVersionConflict: (pep8-naming 0.9.1 (/usr/lib/python3/dist-packages), Requirement.parse('pep8-naming<=0.9.0,>=0.3.3'), {'prospector'})

During handling of the above exception, another exception occurred:

The version of pep8-naming available is only 0.9.1-1 in testing and unstable:

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
$ apt-cache policy python3-pep8-naming
python3-pep8-naming:
  Installed: 0.9.1-1
  Candidate: 0.9.1-1
  Version table:
 *** 0.9.1-1 500
        500 http://deb.debian.org/debian testing/main amd64 Packages
        500 http://deb.debian.org/debian testing/main i386 Packages
        200 http://deb.debian.org/debian unstable/main amd64 Packages
        200 http://deb.debian.org/debian unstable/main i386 Packages
        100 /var/lib/dpkg/status
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

I have not tried to see upstream if python3-pep8-naming 0.9.1 would work
with prospector or not or if a new version of prospector would broaden the
compatibility...


Any help is very welcome,


Rogério Brito.
