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.

Cause: python time resolution is a float, but os.stat as saved by rpm is int Consequence: we compare (1.2 == 1) and fail, when we should succeed Fix: we turn the python timestamp into an int, and only check that Result: we "succeed" (files verify)

Seth's patch

I am reattaching Seth's patch as it's already expired in fpaste.org.
Comment 3 Šimon Lukašík 2010-06-21 10:14:43 UTC 
From what I know: it's not 100% reproducible.

On 2010-06-16 I've seen this behaviour. With another machine that Jan had. 

Now I've tried 4+ machines with exactly same package set with no success.
Comment 4 Šimon Lukašík 2010-06-21 10:37:03 UTC 
Great, I finally reproduced it. Patch works well for me.

Thanks Simon.

Comment 9 Šimon Lukašík 2011-01-25 17:44:46 UTC 
Hello Karel,

Not much I can help here. If I remember correctly, this was not 100%
reproducible. I have tried about 10 fresh installed machines (certainly
not more) and problem appeared.

When I have had affected machine, I have applied Seth's patch manually
and behaviour was correct then.
