Note: This bug is displayed in read-only format because
the product is no longer active in Red Hat Bugzilla.
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.
User was asked how the problem is triggered.
But it is very easy to reproduce starting with *sh:
"""
[pcpa@rhel7 ~]$ unset PATH
bash: sed: No such file or directory
[pcpa@rhel7 ~]$ echo $PATH
bash: sed: No such file or directory
[pcpa@rhel7 ~]$ /bin/tcsh -l
PATH: Undefined variable.
[pcpa@rhel7 ~]$ echo $SHELL
/bin/bash
"""
The problem started with
https://pagure.io/setup/c/78d62a2d107b61b043b712e30b0ce43cd7dcd3c0
and interestingly, setup.spec has this:
* Tue Oct 13 1998 Cristian Gafton <gafton>
- fix the csh.cshrc re: ${PATH} undefined
so, a variant of this issue likely happened before.
The problem happens in recent Fedora and RHEL8 as well.
The problem is triggered with test a user used in development and
regression tests, where $PATH happens to not be set. It was not an
issue in RHEL6, but the changes in RHEL7 cause the problem.
For the moment, the user was told to use pam_env as a temporary
workaround.

[root@qeos-32 ~]# rpm -qf /etc/csh.login
setup-2.8.71-10.el7.noarch
... It's actually setup package who owns that file. You can also see it from the commit you have posted here.

I see the printing itself of "PATH: Undefined variable." as a cosmetic problem as tcsh interpreter simply prints it when a variable isn't defined.
What I see problematic is that previously it set PATH to some default value if undefined, but now does nothing, leaving it empty.
The mentioned patch:
https://pagure.io/setup/c/78d62a2d107b61b043b712e30b0ce43cd7dcd3c0
removes that behavior even it should have influenced PATH only in case when it is defined and not containing /usr/local/sbin /usr/sbin to add it so non-root user can start wireshark by clicking on a desktop icon.
We should fix this.
