Version-Release number of selected component (if applicable): 1.5.3-3.fc29


This is blocking pylint and thus all packages that BR pylint.

Current upstream master works with Python 3.7, but has dropped Python 2 support entirely. I'll try to investigate whether there si a version that supports both.

Comment 3 Miro Hrončok 2018-05-16 11:25:08 UTC 
1.6.x does not work with Python 3.7.
2.x does not work with Python 2.

There might be nothing in between: https://github.com/PyCQA/astroid/issues/539
Comment 4 Miro Hrončok 2018-05-16 11:38:59 UTC 
We might need to (for both astroid and pylint):

 * update to 2.x (or whatever this the pylint version) in rawhide
   * alpha will be released this week
   * drop python2 subpackages
 * introduce python2-astroid and python2-pylint (source) packages (like we did with python2-ipython)

Comment 6 Christian Dersch 2018-05-17 14:15:06 UTC 
Do you already have the required changes to packaging prepared? At least I recognized your review requests for the python2-* packages.

If yes: Feel free to apply them to both packages when you think they're ready. I'm quite busy for the next weeks. Thanks!
Comment 7 Miro Hrončok 2018-05-17 14:54:27 UTC 
The python2- packages are ready, the "main" packages with python3 are not yet ready, I'm waiting for upstream 2.x release actually. Will send a pagure PR and let cstratak review my changes before I merge them. Thanks for the approval.

Upstream fix:

https://github.com/PyCQA/astroid/commit/be874a94b81f2b9404722937f1ea0e105c3c034a
https://github.com/PyCQA/astroid/commit/a4996b4ce7d2a1b651ae984ee3448b8913577c5f

I keep this open, let's wait for a release and if it doesn't happen, those pacthes apply "as is".
