Setting the severity to high. This package is part of the initial bootstrap sequence. Without it, we cannot proceed with the Python 3.9 bootstrap in a Koji side tag. https://fedoraproject.org/wiki/Changes/Python3.9#Important_dates_and_plan The current plan is to follow the "ideal point when we can start rebuilding in Koji" -- that is we need to get this bug fixed approximately in 1 month and 1 week. That includes potential uncovered bugs in packages that depend on this one. Please acknowledge that you have read this message and that you can dedicate time to fix it. If you know already that you won't be able to fix it by the deadline, please let us know ASAP, so we can allocate resources to do that. Thank You. Sorry for the delay, I am aware of the issue and will try to fix it ASAP. Thanks! Just an update on this. Kevin is looking into fixing it, but the bug seems to be related to binutils, and not GDB. We might have to reassign it. Also, I'd be interested in knowing why this error (which seems to be completely unrelated to the Python support on GDB) happens on the copr repository, but not on Rawhide. I'm assuming the GCC being used is newer than the one available on Rawhide. > Also, I'd be interested in knowing why this error (which seems to be completely unrelated to the Python support on GDB) happens on the copr repository, but not on Rawhide. That is a mystery to me as well. There are root logs in case you want to compare them with rawhide root logs.

We don't build newer gcc in that repo. FWIW, I was able to reproduce the problem on Rawhide (outside mock). Even though this is a binutils problem, we should be able to fix this on GDB as well (since GDB carries its own copy of bfd). The following commit fixed the issue upstream:

bfd: Change num_group to unsigned int
The i686/armv7hl buildroots seem to have some problem: https://koji.fedoraproject.org/koji/taskinfo?taskID=43142207 We don't know why this segfault is happening, since we haven't changed anything else other than backport the patch (which is extremely simple). We'll try to find out what's going on. I think this should now be fixed in gdb-9.1-5. Indeed it is. There is another failure with Python 3.9. I've opened a new bugzilla, bz1822715. FEDORA-2020-0bc8abfe7d has been submitted as an update to Fedora 32. https://bodhi.fedoraproject.org/updates/FEDORA-2020-0bc8abfe7d FEDORA-2020-0bc8abfe7d has been pushed to the Fedora 32 testing repository. In short time you'll be able to install the update with the following command: `sudo dnf upgrade --enablerepo=updates-testing --advisory=FEDORA-2020-0bc8abfe7d` You can provide feedback for this update here: https://bodhi.fedoraproject.org/updates/FEDORA-2020-0bc8abfe7d See also https://fedoraproject.org/wiki/QA:Updates_Testing for more information on how to test updates. FEDORA-2020-0bc8abfe7d has been pushed to the Fedora 32 stable repository. If problem still persists, please make note of it in this bug report. |

You can follow these instructions to test locally in mock if your package builds with Python 3.9: https://copr.fedorainfracloud.org/coprs/g/python/python3.9/ Let us know here if you have any questions. Python 3.9 will be included in Fedora 33. To make that update smoother, we're building Fedora packages with early pre-releases of Python 3.9. A build failure prevents us from testing all dependent packages (transitive [Build]Requires), so if this package is required a lot, it's important for us to get it fixed soon. We'd appreciate help from the people who know this package best, but if you don't want to work on this now, let us know so we can try to work around it on our side.
