dh-python now generates dependencies on python2 instead of python
For Python2 packages, dh-python 4.20191017 now rewrites any python shebang to
/usr/bin/python2 and generates dependencies on python2 instead of python.
The py2removal bugs have a section
"""
- If the package has still many users (popcon >= 300), or is needed to
build another package which cannot be removed, document that by
adding the "py2keep" user tag (not replacing the py2remove tag),
using the debian-python@lists.debian.org user. Also any
dependencies on an unversioned python package (python, python-dev)
must not be used, same with the python shebang. These have to be
replaced by python2/python2.7 dependencies and shebang.
"""
As seen with the recent python-crypto upload, the package now has no dependency
on python anymore in the binary packages, and it doesn't have any python,
python-dev build-dependencies anymore.
Also seen in python-crypto, the python2 autopkg test calls python, and fails
because python is not a dependency of python-crypto anymore. This needs fixing.
If we need to ship Python2 in bullseye, then the python, python-dev, python-dbg,
python-doc, libpython-stdlib, libpython-dev binary packages will be removed
before the release.
With that change, python-crypto is in a form to ship with bullseye (if
python-crypto is still needed for some application that we want to keep).
Application packages are likely to need a change in the build dependencies to
ship with bullseye, if needed.
