Hi,

The package “bap” and “python-glcontext” have hash mismatches.  In both cases,
it is because upstream changed the lable tag.  The Git tag pointed some
content and now the same Git tag points another content.

The path I follow for fixing this issue: The first patch of each package does
not modify the checksum hash that had been introduced in Guix; the patch just
restore the correspondance with the immutable content.

Since we are here :-) the second patch of each update them to the last version
available – keeping the explicit commit because there is no reason that
upstream will not replace the Git tag again.

*Please note*.  Because of the referencing to mutable Git tag as reference for
Guix source package, the packages “bap” and “python-glcontext” for all the
Guix revisions containing the first tag reference (now wrong; pointing to past
content) are now broken forever.  They are still installable because they are
still available as substitutes in the build farms but they can vanish at the
next garbage collection of the substitute farms.

Upstream applies the policy they want for their mutable Git tags.  They want
to append ’-alpha’ for some pre-release and do not version the pre-release
candidates.  Fine.  They want to replace the content tagged as a release by
another content and rewrite the tag.  Fine.

However, must we know what is the upstream policy when packaging?  No.

Therefore, rely on mutable Git tag leads to troubles when it is easy to avoid
them: explicity refer to the commit hash in the Guix definition of the
package.  I will open again a discussion about that.

For the record, here some more explanations.

* About bap
===========

If I read correctly, “bap” had been updated to 2.5.0-alpha in Guix with:

        404df667e3b06f1e9a416c956e53c03ca3642140
        AuthorDate: Sun Jun 19 08:43:00 2022 +0200
        CommitDate: Tue Jun 28 19:34:50 2022 +0200

Today, an user gets the source of “bap” because the Guix project still
stores the checkout substitute.  But we cannot predict when the store of
the build farms will be garbage collected and this checkout substitute
will disappear, so making this package broken for many Guix revisions.

To be precise, this source of the package “bap” are unreachable by the Guix
recipe since Jul 8 2022!  Other said, the source of “bap” was correct only few
days and broken since more than one year, it is unsatisfactory.
