Hi Guix!

this patch (going to core-updates) removes files from the output of
python2 and python3, in an attempt to save some space. First, I noticed
that python3 shipped windows binaries in its source distribution and
installs them to the output, in lib/python3.8/distutils/command/*.exe,
lib/python3.8/site-packages/*.exe and
lib/python3.8/site-packages/pip/_vendor/distlib/*.exe. I remove them
from the snippet, so they should not be installed anymore.

I also noticed that python installs files that were built during the
test phase, so I remove them, but we need to check they are not
actually needed. Other distros ship them in a separate package, so
maybe we could have a separate test output if this is causing issues?

I haven't yet tested the patch, because it needs to rebuild part of the
bootstrap chain. I'll report progress and update my patch depending
on the results!

I got stuck on python-minimal with test-asyncio but then it didn't hang
the second time I ran the build. I don't have a good pure python package
I can think of to test the change.

I discovered other .exe in python3, so this updated patch deletes them.
Since I modify the python from commencement.scm by changing a phase in
python-2.7, I decided to also change the definition there to remove the
offending files.

I managed to build up to python-3.9 without any issue, but haven't
tested building more than a handful of python packages.

Unless it causes bootstrapping issues, I recommend removing those files
from a snippet so that ‘guix build -S python’ returns the cleaned-up
source.

WDYT?

Thanks,
Ludo’.

Hi, sorry for the late reply. I need to use unzip on these files to
remove some of their content, and rezip them later. How can I do that
from a snippet?

Oh right, the bit that unzips/rezips .whl files cannot easily be done
from a snippet, so better keep it as a phase.

Deleting *.exe can be done from a snippet though.

BTW, the patch reads:

   (find-files "Lib/distutils/command" ".*.exe$")

but the regexp should be:

  "\\.exe$"

(“.*” is unnecessary, but the dot before “exe” must be protected.)

Likewise for:

  (find-files "Lib/ensurepip" ".*.whl$")

Thanks,
Ludo’.
