Description Kjetil T. Homme 2009-07-31 09:07:16 EDT
Description of problem:
Sometimes yum can choose the wrong provider of a file, and thereby pull in components from Tomcat, GNOME or KDE (all observed).

Version-Release number of selected component (if applicable):
yum-3.2.19-18.el5_3.1


How reproducible:
When yum's metadata is in this state, perfectly.  How to arrive at this metadata is unknown.

Steps to Reproduce:
1. yum upgrade
  
Actual results:
Updating:
 bind-libs                 x86_64 30:9.3.4-10.P1.el5_3.3 rhel5_os_updates 869 k
 bind-utils                x86_64 30:9.3.4-10.P1.el5_3.3 rhel5_os_updates 173 k
 python                    x86_64 2.4.3-24.el5_3.6       rhel5_os_updates 5.9 M
Installing for dependencies:
 alsa-lib                  x86_64 1.0.17-1.el5           rhel5_os_updates 414 k
 ant                       x86_64 1.6.5-2jpp.2           rhel5_os_updates 2.3 M
...
 xml-commons-resolver      x86_64 1.1-1jpp.12            rhel5_os_updates 171 k

Expected results:
No additional packages should be installed.

Additional info:

It seems to be related to this state:

# yum deplist gamin-python
  dependency: /usr/lib64/python2.4
   provider: tomcat5-admin-webapps.x86_64 5.5.23-0jpp.7.el5_3.2
   provider: python.x86_64 2.4.3-24.el5

tomcat5-admin-webapps is not installed on this system.  on another system, it listed kdelibs-devel.i386 as a provider of /usr/lib/python2.4.

after "yum clean all", we get the expected output of just the python packages from rhel5_os and rhel5_os_updates.


resolvedep on its own works:

# yum resolvedep /usr/lib64/python2.4
Excluding Packages in global exclude list
Finished
Importing additional filelist information
0:python-2.4.3-24.el5.x86_64

we tried to force reloads of primary and filelist (added a space to the files and updated the checksums in repomd.xml), but it didn't make any difference.  "yum clean dbcache" is sufficient.  in other words, it looks like some inconsistency has developed in the sqlite files.

another twist:  deleting *just* rhel5_os_updates/filelists.xml.gz.sqlite changes the behaviour, but it's still bogus:
