Package: dh-python
Version: 4.20200315
Severity: important
Currently (with python3.7 and 3.8 supported and python3.8 as default),
dh_python3 generates a python3.7 dependency for python3-pip. This is
not needed and actively harmful.
Please see the attached verbose dh_python3 log. It shows the entry_points.txt
file that makes it into the package is the one from python3.7, which
leads to the python3.7 dependency because of the entry point.
I can work around this by build-depending on python3 instead of
python3-all, but then the package isn't byte compiled against all
supported versions during build, so we may end up hiding problems.
Two related points:
If a version specific entry point is going to make it into the binary,
then it should be the default version.
For an arch:all package we shouldn't have version specific entry points
because that will lead to needing to rebuild the package when the
default version changes.
Currently we get the following entry points (note: we only ship the pip3
entry point):
python3.7 build:
[console_scripts]
pip = pip._internal.cli.main:main
pip3 = pip._internal.cli.main:main
pip3.7 = pip._internal.cli.main:main
This is what makes it in the package.
python3.8 build:
[console_scripts]
pip = pip._internal.cli.main:main
pip3 = pip._internal.cli.main:main
pip3.8 = pip._internal.cli.main:main
This would be an improvement since at least the version specific depends
would be on the default interpreter.
What I would really like to be able to do is:
[console_scripts]
pip3 = pip._internal.cli.main:main
I don't think this is urgent because I can work around the problem, but
it should be addressed at some point.
Thanks,
Scott K
