[bug#38824] gnu: mercurial: Update to 5.2.1.

Dear Guix,

It looks like we can straightforwardly update to Mercurial 5.2.1, and in the
process move away from python-2 for this package.

Attached is a patch to do so.

Kind regards,
Roel Janssen

Thanks for the submission. We do have a python-nose package. Is this
different from the nose unit mentioned in the rationale for disabling
the tests?

Thanks for responding.  I suppose it's the same python-nose.  Running the tests
(with or without python-nose in the "inputs") fail with the following error:

---
TypeError: '<' not supported between instances of 'bytes' and 'str'
command "python" "-c" "import setuptools,
tokenize;__file__='setup.py';f=getattr(tokenize, 'open',
open)(__file__);code=f.read().replace('\\r\\n',
'\\n');f.close();exec(compile(code, __file__, 'exec'))" "test" failed with
status 1
---

I don't know much about Python, so I'm not sure whether the test suite just
hasn't been made Python-3-compatible, or whether it's something else, and
whether this has always been a problem, or whether it was introduced by this
update.

Kind regards,
Roel Janssen

I can confirm Roel Janssen's guess that python-nose is the 
relevant package and that it provides the nose unit test runner.

From https://www.mercurial-scm.org/wiki/Python3 as of this 
writing:

The output I obtained from running `python3 -m nose` in the 
repository's root is attached.  Looking at 
e.g. mercurial/pycompat.py shows that Mercurial's devs are indeed 
aware of these Python3 compatibility issues:

I think that for now the options are to
1. continue using Python2 for Mercurial;
2. use Python3 but disable all tests, as Janssen's patch suggests;
3. use Python3 but disable the known-failing tests; or
4. hold off on updating the package until upstream supports 
Python3 across its entire test suite.

Of those three, I am most in favor of the third option.  I would 
be glad to submit a patch that implements it if there is agreement 
to take that direction.

I agree that option 3 (with a link to the upstream discussion) is the
right way to go forward.

Thanks!

I am also in agreement that working-around the failing tests is the best option, with a backup of just disabling the tests until the python3 incompatibilities are resolved. We need to work away from python2 wherever possible. Since the upstream is aware of the problem I see avoiding python2 as a reasonable alternative to work-arounds.

That seems orthogonal to the discussed patch though, seeing as tests
have been disabled in Mercurial since forever.
