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 Patrik Kis 2012-06-21 14:46:30 UTC 
Description of problem:
Test /CoreOS/yum/Regression/bz448772-circular-requires-obsoletes is failing in " ./Update-packages-from-obsoletes-loop" part.

Version-Release number of selected component (if applicable):
yum-3.4.3-27.el7.noarch

How reproducible:
always

Steps to Reproduce:

1. There are two packages with these attributes: 
# rpm -qp --obsoletes test-ddd-0.2-2.x86_64.rpm
test-ccc  
# rpm -qp --obsoletes test-ccc-0.2-2.x86_64.rpm
test-ddd  

2. It is not possible to install the circular obsolete packages and yum return 0.

# yum -d 9 install test-ccc test-ddd

NOTE1: The same happen with localinstall.
NOTE2: On RHEL6 booth packages were installed.
NOTE3: "obsoletes = True: in booth RHEL6 and RHEL7 test.
NOTE4: The behavior of rpm has also changed in RHEL7: https://bugzilla.redhat.com/show_bug.cgi?id=804069#c6
NOTE5: The same happen also with update/localupdate, i.e. the packages are not updated and yum exit with 0. On RHEL6 boot packages were updated.

Actual results:

Install/update fail and yum exit with 0.

Expected results:

It is a question is the correct behavior:
 - IMHO, if the the old RHEL6 behavior (booth are installed/updated) are changed in rpm, it should also change in yum.
 - So, I think either install one pkg and return 0 or don't install anything and return error.

Another info:

These is another case, where a package which obsoletes itself. This package is not installed and yum return 0, while on RHEL6 it was installed.
This is most probably the same issue as above, just writing it here, for case it would not be.
Comment 2 James Antill 2012-11-12 19:28:02 UTC 
 This is fixed upstream, not sure if it's made it into RHEL-7 yet though (tested in 6.4 though).
Comment 3 Karel Srot 2012-11-14 16:06:25 UTC 
Still failing on current RHEL7  with yum-3.4.3-46.el7.noarch
Switching back to assigned
Comment 4 James Antill 2013-06-18 16:22:32 UTC 
 Changelog says it made it into rawhide in -48, should be there now for sure though :).
Comment 5 Karel Srot 2013-08-29 11:39:22 UTC 
Hi James, Patrik,

current rpm behavior is that just one package is installed (this is expected as described in bug804069#c7)

current yum behavior is as follows:

Installing:
 test-ccc       x86_64        0.2-2         myrepo          1.6 k
     replacing  test-ddd.x86_64 0.1-1
 test-ddd       x86_64        0.2-2         myrepo          1.6 k
     replacing  test-ccc.x86_64 0.1-1

Rpmdb checksum is invalid: dCDPT(pkg checksums): test-ddd.x86_64 0:0.2-2 - u
:: [   FAIL   ] :: Running 'yum --disablerepo='*' --enablerepo=myrepo -y update' (Expected 0, got 1)


So yum somehow detects that one package wasn't installed and reports the rpmdb invalid checksum error and exits with 1.
This is different from the requirement described above but still it makes sense to me.

What do you think?
Comment 6 Patrik Kis 2013-08-29 12:18:15 UTC 
It is ok form me if the installation ends with error. Assuming what was said in bug 804069, that these circular obsoleted packages can be considered as packaging error, IMHO returning error and let the admins know that there is something bad with the packages/installation is probably the best option here.
Comment 8 James Antill 2014-04-07 21:09:15 UTC 
 Yeh, rpm does it's own thing but tells us what happened ... which is why yum complains (it sees something different happened than what it thought would happen).
 It's far from perfect, but it is what it is.
