python-joblib-0.13.0 fails to build with Python 3.8

It seems that test_hashing fails on various test cases and also test_numpy_pickle

Example snippet:

________ test_hashes_stay_the_same[This is a string to hash-expected0] _________

to_hash = 'This is a string to hash'
expected = {'py2': '80436ada343b0d79a99bfd8883a96e45', 'py3': '71b3f47df22cb19431d85d92d0b230b2'}

Please respond.

Comment 2 Sergio Pascual 2019-07-11 08:03:56 UTC
I can update to the latest joblib, but is python 3 only. scikit-learn depends on it and it still has the pyhton2 subpackage.

Can I drop the python2 subpackage of scikit-learn?

Comment 3 Miro Hrončok 2019-07-11 08:32:16 UTC
scikit-learn has no Python 2 subpackage in rawhide, neither does joblib.

Comment 4 Sergio Pascual 2019-07-11 10:08:04 UTC

Great!

I have updated to 0.13.2 
https://koji.fedoraproject.org/koji/taskinfo?taskID=36182499

Could you check if you still get the same problem?

CodeType has a new signature in 3.8. See https://docs.python.org/3.8/whatsnew/3.8.html - search for CodeType.

Comment 6 Sergio Pascual 2019-07-11 10:38:12 UTC
In fact, cloudpickle is a bundled package (0.8.0). Even the upstream version of cloudpickle has exactly the same problem

https://github.com/cloudpipe/cloudpickle/blob/master/cloudpickle/cloudpickle.py#L367

Comment 7 Miro Hrončok 2019-07-11 11:06:13 UTC
The linked code is not used on 3.8. Please, just unbundle cloudpickle and you should be good.

Comment 8 Sergio Pascual 2019-07-11 16:05:04 UTC
I have unbundled cloudpickle in the last joblib

Comment 10 Ben Cotton 2019-08-13 16:47:14 UTC
This bug appears to have been reported against 'rawhide' during the Fedora 31 development cycle.
Changing version to '31'.

Comment 11 Miro Hrončok 2019-08-14 22:24:15 UTC
The coordinated rebuild of Python 3.8 has started in the `f32-python` side tag.

If you figure out how to rebuild this package, please don't rebuild it in regular rawhide, but use the side tag instead:

    on branch master:
    $ fedpkg build --target=f32-python

To wait for a build to show up in the side tag, do:

    $ koji wait-repo f32-python --build=<nvr>

Where <nvr> is name-version-release of the source package, e.g. python-foo-1.1-2.fc32.

An updated mock config is posted at:
http://copr.fedorainfracloud.org/coprs/g/python/python3.8/

Note that it will take a while before the essential packages are rebuilt, so don't expect all your dependencies to be available right away.

Thanks. Let us know if you need up to date info, or if you have any questions.



PS this message is mass posted to all the bugs that block the PYTHON38 bug. If this is also a Fedora 31 FTBFS bug and you manage to fix it, you can do a f31 build as usual:

    on branch f31:
    $ fedpkg build

Comment 12 Miro Hrončok 2019-08-21 16:34:28 UTC
The f32-python side tag has been merged. In order to rebuild the package, do it in regular rawhide, but please wait until python3-3.8 is tagged:

  $ koji wait-repo f32-build --build python3-3.8.0~b3-3.fc32


If your built already started in f32-python, after it is finished, please tag it to rawhide with:

  $ koji tag-build f32-pending <nvr>

For example:

  $ koji tag-build f32-pending libreoffice-6.3.0.4-3.fc32

Thanks!

Comment 13 Miro Hrončok 2019-08-21 17:29:03 UTC
(Python 3.8 has landed in the rawhide buildroot.)
