Description Jan Pazdziora 2019-01-22 09:15:29 UTC
+++ This bug was initially created as a clone of Bug #1336913 +++

With a fresh fc24 install, ipa-client-install prints the following warning:

# ipa-client-install -N
WARNING: yacc table file version is out of date
Discovery was successful!

and then proceeds to configure the client as normal.  Nothing seems to be broken, but I didn't do anything obviously odd and this warning is esoteric.

python-pycparser-2.14-6.fc24 has been pushed to the Fedora 24 stable repository. If problems still persist, please make note of it in this bug report.

Comment 1 Jan Pazdziora 2019-01-22 09:18:27 UTC
The issue is back in Fedora rawhide with python3-pycparser-2.14-15.fc29.noarch.

installed, running python3 with the snippet from bug 1336913 comment 6 causes lextab.py and yacctab.py to be created in the current directory.

Also, that snippet code actually produces some tracebacks as well:

Comment 2 Christian Heimes 2019-01-22 09:29:54 UTC
The regeneration of yacctab is caused by a packaging mismatch between python3-pycparser and python-ply. Fedora 30 has python-ply-3.11-1.fc30 but python-pycparsing was created with python-ply-3.9-8.fc29. The new version of python-ply has tabversion 3.10, but the yacctab of python-pycparser-2.14-15 has tabversion 3.8. Since the tabversion number is different, the pre-generated yacctab is not compatible and is rebuilt automatically. Please rebuild pycparser with latest ply.

In order to prevent this issue in the future, the pycparser package should have a hard dependency on the tabversion provided by python-ply.

Comment 3 Orion Poplawski 2019-01-22 14:57:42 UTC
Re-assigning to the proper component (python3-pycparser is for EPEL only)

Comment 4 Jan Pazdziora 2019-02-13 15:46:02 UTC
Hello, any chance of getting the package rebuilt and this issue fixed? Looking at https://koji.fedoraproject.org/koji/packageinfo?packageID=16664, the automatic rebuilds that rel-eng does failed ...

Comment 5 Christian Heimes 2019-02-26 10:30:06 UTC
https://src.fedoraproject.org/rpms/python-pycparser/pull-request/2#request_diff addresses the mass-rebuild issue and introduced a harder version dependency on python-ply to avoid the "yacc table file version is out of date" problem in the future.

Comment 6 Jan Pazdziora 2019-03-07 14:45:22 UTC
I can see that the pull request was merged and python-pycparser-2.14-18.fc31 was built for rawhide: https://koji.fedoraproject.org/koji/buildinfo?buildID=1220953.

However, since this bugzilla was filed, Fedora 30 was branched, so the patch and new build is also needed on the f30 branch and in f30 target.

Comment 7 Alexander Bokovoy 2019-03-18 09:03:47 UTC
Eric, is it possible to get F30 build as well?
