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 Jon McKenzie 2014-01-03 15:23:11 UTC 
Description of problem:

The 'repoquery' utility dependency resolution sometimes displays different results than yum


Version-Release number of selected component (if applicable):

yum-utils-1.1.30-14


How reproducible:

Very


Steps to Reproduce:
1. Use the 'ant' package as the test case. First, ensure the 'ant' package is not installed:

# rpm -q ant
package ant is not installed

2. Query the dependencies of 'ant' using repoquery (first wiping yum cache to ensure a consistent baseline):

# yum clean all
Loaded plugins: fastestmirror, priorities
Cleaning repos: centos6-server-x86_64
Cleaning up Everything
Cleaning up list of fastest mirrors
# repoquery --requires --resolve ant
ant-0:1.7.1-13.el6.x86_64
glibc-0:2.12-1.132.el6.i686
bash-0:4.1.2-15.el6_4.x86_64
java-1.6.0-openjdk-devel-1:1.6.0.0-1.66.1.13.0.el6.x86_64
xml-commons-apis-0:1.3.04-3.6.el6.x86_64
libgcc-0:4.4.7-4.el6.x86_64
jpackage-utils-0:1.7.5-3.12.el6.noarch
ant-0:1.7.1-13.el6.x86_64
libgcj-0:4.4.7-4.el6.x86_64
zlib-0:1.2.3-29.el6.x86_64
xerces-j2-0:2.7.1-12.6.el6_0.x86_64
glibc-0:2.12-1.132.el6.x86_64
java-1.5.0-gcj-devel-0:1.5.0.0-29.1.el6.x86_64

3. Attempt to install 'ant' via yum. Notice in the output below that "java-1.5.0-gcj-devel" does not appear as a dependency (even though it appears as a dependency via repoquery):

# yum install ant
Loaded plugins: fastestmirror, priorities

Is this ok [y/N]: 

4. Validate that java-1.5.0-gcj-devel-0:1.5.0.0-29.1.el6.x86_64 isn't already installed (thus fulfilling the "dependency"):

# rpm -q java-1.5.0-gcj-devel
package java-1.5.0-gcj-devel is not installed

Actual results:

Querying through 'repoquery' displays some different dependencies than through 'yum'

Expected results:

Querying through 'repoquery' displays the same dependencies as the 'yum' command. Since yum and repoquery are both looking at the same repository and repodata, they should have the same information.
Comment 2 Valentina Mukhamedzhanova 2014-03-26 09:50:28 UTC 
repoquery --requires --resolve does not do depsolving, it just resolves capabilities to originating packages. For example, pidgin requires /bin/sh:

$ repoquery --requires pidgin
/bin/sh

$ repoquery --requires --resolve pidgin
