[bug#36026] [PATCH 0/4] Update Conda

[Pierre Neidhardt]

Recent conda needs a separate python-conda-package-handling library.
This library requires a libarchive built with zstd support.
So far so good, except that python-libarchive-c does not seem to support zstd in its source code.

I've reported the issue upstream
(https://github.com/conda/conda-package-handling/issues/14) but
according to them python-libarchive-c is fine.

I don't have enough Python knowledge to understand whether upstream is right
	or if there is indeed something fishy with python-libarchive-c.
Pierre Neidhardt (4):
  gnu: libarchive: Add zstd support.
  gnu: python-libarchive-c: Explicitly rely on latest libarchive.
  gnu: Add python-conda-package-handling.
  gnu: python-conda: Update to 4.7.0.

[bug#36026] [PATCH 1/4] gnu: libarchive: Add zstd support.

[Ludovic Courtès]

Hi Pierre,

Pierre Neidhardt <mail@ambrevar.xyz> skribis:

> * gnu/packages/backup.scm (libarchive)[inputs]: Include zstd.
> [arguments]: Build against zstd.

Here you’re modifying ‘libarchive’, which has tons of dependents.

If you instead modify ‘libarchive-3.3.3’, you’ll be able to apply it
directly on master, and follow up with a patch to apply the changes on
‘libarchive’ itself in ‘core-updates’.

WDYT?

Thanks,
Ludo’.

Apart from the rebuild issue with patch #1 that needs to be addressed,
it LGTM!

Thanks for the clarifications around the libarchive business.

The problem is that this patch still does not work because
python-libarchive-c does not support zstd, which
python-conda-package-handling needs.  I don't understand how upstream
does this.  I've reported it upstream:

https://github.com/conda/conda-package-handling/issues/14

My knowledge of python is not enough to understand if upstream is wrong
or if I'm using python-libarchive-c incorrectly.

Does this actually work?  If it does: congratulations!

I tried to upgrade conda a while ago, but I got stuck:

   https://github.com/conda/conda/issues/8151

How did you overcome these problems?  I had to patch a lot of things and
even then couldn’t make it work.  Did I miss something obvious?

I’m glad you took care of this and I didn’t have to become the Conda
guy… :)

Do none of the tests now require network access?  Are the tests actually
still run?

Hi Ricardo,

Sorry to kill your enthusiasm, but nope, it does not work :/
The is an issue building the conda-package-handling dependency.  See the
prior discussion for the details.

So I haven't even reached to the issues you've hinted at on GitHub.
Don't know if they still apply with my patch, we can only figure it out
one step at a time :p
