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

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.
