Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.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.

Version-Release number of selected component (if applicable):
389-ds-base-1.4.1.3-7.module+el8.1.0+4150+5b8c2c1f.x86_64


How reproducible:
always

Steps to Reproduce:
1. Rebuild 389-ds-base with ASAN
2. Run 
tests/suites/basic/basic_test.py::test_basic_backup
tests/suites/replication/encryption_cl5_test.py::test_algorithm_unhashed[AES]	
tests/suites/replication/changelog_test.py::test_verify_changelog_offline_backup	

Actual results:
Memory leaks errors are reported by ASAN

Expected results:
No memory leaks

https://pagure.io/389-ds-base/issue/51016

Comment 4 Simon Pichugin 2020-04-09 16:39:01 UTC
The leaks from the next tests will be addressed in https://pagure.io/389-ds-base/issue/49562

    tests/suites/replication/encryption_cl5_test.py::test_algorithm_unhashed[AES]
    tests/suites/replication/changelog_test.py::test_verify_changelog_offline_backup

I will post the BZ number later here.

Comment 7 Viktor Ashirov 2020-06-02 12:39:42 UTC
Build tested: 389-ds-base-1.4.3.8-2.1asan.el8.x86_64 

The following tests pass and don't produce memory leaks:
dirsrvtests/tests/suites/replication/changelog_test.py::test_verify_changelog_offline_backup
dirsrvtests/tests/suites/basic/basic_test.py::test_basic_backup

Test dirsrvtests/tests/suites/replication/encryption_cl5_test.py::test_algorithm_unhashed[AES] still produces errors, but as mentioned in comment #4, this will be addressed in a separate bz.

Marking as VERIFIED.
