RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Panu Matilainen 2019-06-27 10:23:07 UTC
Description of problem:
Commit 046d218998fa972862e6ed9bc6542a1035fe656f dropped %__python as the first argument to brp-python-bytecompile, shifting what are positional arguments without adjusting the script accordingly.

This means that the script still expects the path of the python interpreter as the first argument, but receives "1" from %_python_bytecompile_errors_terminate_build macro. The script uses this for the value of $default_python:

# If we don't have a default python interpreter, we cannot proceed
default_python=${1:-/usr/bin/python}
if [ ! -x "$default_python" ]; then
        exit 0
fi

...and presumably will exist because there's no executable named "1". With the result that the script will never do any byte-compilation at all on RHEL.

Comment 1 Panu Matilainen 2019-06-27 10:27:53 UTC
FWIW, the Fedora-side of this issue is tracked in bug 1721147

Comment 2 Miro Hrončok 2019-06-27 10:40:05 UTC
for RHEL, I suggest we just drop the "default Python interpreter" part altogether.

Comment 4 Miro Hrončok 2019-07-10 12:40:44 UTC
What Fedora change?

Comment 5 Miro Hrončok 2019-07-10 12:42:12 UTC
To shed some light on this:

On RHEL8, brp-python-bytecompile is called with wrong arguments

On Fedora, brp-python-bytecompile is called with correct arguments

Daniel, ping?

> What Fedora change?
I was referring to bug#1721147 as I thought that we need to fix it first.

Thanks for clarification.

Restoring previous qa_ack+ as agreed earlier.

Comment 11 Michal Domonkos 2020-02-24 10:46:51 UTC
So Panu and I investigated this a bit more, and it turns out the regular python binaries/libraries within the /usr/lib*/python*/ directories are not affected by this issue; they continue to be bytecompiled just fine on RHEL-8.  What is affected is the ability of the script to bytecompile other locations, and the %{?_python_bytecompile_errors_terminate_build} macro which is not honored anymore.

Luckily, there's an easy way to fix this for 8.2, so I'm switching the ITR back and will do a build in a few moments.
