new 'wheel' dependencies impact on pip freeze

[sbidoul]

pip freeze excludes pip, setuptools, and wheel by default, unless the --all option is passed.

Now that wheel depends on packaging which in turn depends on pyparsing and six, new, possibly unexpected lines are emitted by pip freeze.

I'm not sure yet if it is a problem in practice.

This issue went away with wheel 0.35.1 which now vendors packaging.tags. Thanks @agronholm !

Note that vendoring is only an interim solution until we can get rid of the unnecessary dependencies. One plan is to separate the "tags" part of packaging into its own library. If this happens, wheel will add an install dependency on that.

This issue is probably not worth keeping around anymore as pip freeze will show setuptools and wheel starting on Python 3.12 and higher.

pip/src/pip/_internal/commands/freeze.py

Lines 12 to 22 in 4d09e3c

	def _should_suppress_build_backends() -> bool:
	return sys.version_info < (3, 12)
	def _dev_pkgs() -> AbstractSet[str]:
	pkgs = {"pip"}
	if _should_suppress_build_backends():
	pkgs |= {"setuptools", "distribute", "wheel"}
	return pkgs

Yes; I don’t think this is relevant anymore since setuptools and wheel are no longer “built-in” (in quotes).
