Questions regarding Python packaging

[Tanguy Le Carrour]

Hi Guix!

I have some general questions regarding Python packaging, that are not
directly related to the "poetry build system" I'm currently working on.

I've just learned, by accident (working on `python-keyring` [1]), that
`python setup.py install` was somehow deprecated in favor of tools like
`pep517` or `build`.

So, I've tried packaging `python-keyring` with those two…

`pep517` keeps on trying to download dependencies, which won't work.

`build` crashes with "ZIP does not support timestamps before 1980",
which, I guess is related to the fact that everything in the store is
timestamped to January 1st 1970.

Does anyone have a opinion on Python packaging and how it should be done?
Any idea how I can circumvent the timestamps problem? Is this fish too
big for me?!

Any help or advice welcome! Thanks!

     Keyring package version is set to 0.0.0, this might be related to
     the fact that, upstream, they build it with `python -m pep517.build .`,
     not with `python setup.py install`… but it could also not be
     related at all! But in order to be sure, I have to try!
