Bug 223603 – pylint-2.7.2 fails to autoinstall on Py3

• Component: Tools / Tests
• Status: ASSIGNED

[Sam Sneddon [:gsnedders]]

Registering pylint-2.7.2 leads to:

Traceback (most recent call last):
  File "/Volumes/gsnedders/projects/Safari/OpenSource/Tools/Scripts/webkitpy/test/main.py", line 356, in <module>
    sys.exit(main())
  File "/Volumes/gsnedders/projects/Safari/OpenSource/Tools/Scripts/webkitpy/test/main.py", line 111, in main
    return not tester.run()
  File "/Volumes/gsnedders/projects/Safari/OpenSource/Tools/Scripts/webkitpy/test/main.py", line 184, in run
    return self._run_tests(names)
  File "/Volumes/gsnedders/projects/Safari/OpenSource/Tools/Scripts/webkitpy/test/main.py", line 191, in _run_tests
    AutoInstall.install_everything()
  File "/Volumes/gsnedders/projects/Safari/OpenSource/Tools/Scripts/libraries/webkitcorepy/webkitcorepy/autoinstall.py", line 555, in install_everything
    package.install()
  File "/Volumes/gsnedders/projects/Safari/OpenSource/Tools/Scripts/libraries/webkitcorepy/webkitcorepy/autoinstall.py", line 259, in install
    raise ValueError('No archives for {}-{} found'.format(self.pypi_name, self.version))
ValueError: No archives for pylint-2.7.2 found

This is surprising, given https://pypi.org/project/pylint/2.7.2/#files looks no different to https://pypi.org/project/pylint/2.6.2/#files which works fine?

This is because the index has 'data-requires-python': '~=3.6', and webkitcorepy.version.Version doesn't support PEP 440 and doesn't support the compatible release operator (https://peps.python.org/pep-0440/#compatible-release).

Note we never actually had pylint==2.7.2 as a distribution that was registered; this is just a clear example of a bug in the AutoInstaller.
