Description Charalampos Stratakis 2018-04-05 16:56:43 UTC
Currently dpdk depends on python2 while the package is python3 compatible. Could it be changed to require python3 instead?

Currently the dpdk-examples and dpdk-tools subpackages drag usr/bin/python2 due to shebangs within python scripts pointing to python2 (those will need to be changed during %prep), the devel subpackage requires python2 and the tools subpackage requires python2-pyelftools as runtime dependencies.

Additionally there is a build time dependency on python2-sphinx (I replaced it with python3 and things built fine).

Comment 1 Neil Horman 2018-04-05 18:12:38 UTC
just tested dpdk-pmdinfo (the utility that runs with python2-pyelftools) and it works fine with the python3 library variants.

Comment 2 Charalampos Stratakis 2018-04-06 18:38:30 UTC
Thanks for the change!

It seems though that the sed [0] is not actually working and the shebangs keep pointing at python2. Also would it be possible to push those changes to F28 as well?


Comment 3 Neil Horman 2018-04-09 11:20:50 UTC
So, ideally, that shouldn't matter, as when the cutover happens to python3, /usr/bin/env python will start pointing there, but yes, we should fix the conversion now

Comment 4 Neil Horman 2018-04-09 14:07:08 UTC
Um, actually, I just built this locally, and it appears that all the python scripts that I see are appropriately converted, where are you seeing that that is not the case?

Comment 6 Neil Horman 2018-04-09 14:43:15 UTC
yeah, I can sync the changes, but note that the last update reved the epoch on dpdk to bring it into sync with requirements for OVS (which means a version downgrade).  I don't expect it will be a huge problem, but please keep it in mind

This bug appears to have been reported against 'rawhide' during the Fedora 29 development cycle.
Changing version to '29'.

Comment 10 Petr Viktorin (pviktori) 2019-03-19 14:26:35 UTC
This ids py3-only, at least on Rawhide.
