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the product is no longer active in Red Hat Bugzilla.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.

Build Identifier:
Calling the clear method on a StrDict will cause a segfault if converted to a string afterwards.
$ sudo dnf list installed | grep libcomps
libcomps.x86_64 0.1.11-4.el8 @rhel-8-for-x86_64-baseos-rpms
libcomps-devel.x86_64 0.1.11-4.el8 @rhel-8-for-x86_64-baseos-rpms
python3-libcomps.x86_64 0.1.11-4.el8 @rhel-8-for-x86_64-baseos-rpms
Running this as a script will cause the segfault everytime:
import libcomps
import urllib.request
url = 'http://mirror.metrocast.net/fedora/epel/8/Everything/x86_64/repodata/7566a18455054e4ce6b28bda7c181f66dd9958ed35c66f2b23612fa1f1f5c591-comps-Everything.x86_64.xml'
file_path = '/tmp/testcomp.xml'
urllib.request.urlretrieve(url, file_path)
comps = libcomps.Comps()
comps.fromxml_f(file_path)
#printing comp file works fine
print(comps.toxml_str())
#calling clear() on a StrDict
comps.categories[0].name_by_lang.clear()
# segfault occurs:
print(comps.toxml_str())
Output:
Fatal Python error: Segmentation fault
Current thread 0x00007f147aad6640 (most recent call first):
File "<stdin>", line 1 in <module>
Segmentation fault (core dumped)
Reproducible: Always
Steps to Reproduce:
See above
Actual Results:
segfault
Expected Results:
no segfault
A work around is to create and assign a new empty StrDict object:
comps.categories[0].name_by_lang = libcomps.StrDict()
