[Spacewalk-list] spacecmd system_listupgrades not working

[Andreas Dijkman]

Is the removal of duplicates the solution? Because default on a RHEL-derived system, RPM/YUM leaves the 3 latest kernel-packages on the system, so you can boot the system with the old kernel of the new kernel is not working for you.

Maybe the better solution would be to check if there are older packages on the system. If there are older packages and the version to which those packages could be upgraded is already present on the system, the upgrades aren't listed. This could also comes in handy if you have multiple version of a package on your system. For instance, the installation or upgrade of JDK7 by RPM doesn't remove the old versions. If you have 3 older versions of the JDK7 on your environment and not the latest, the update gets listed 4 times!! Once for every old version and once because the latest versions is not installed yet. So you get 3 false positives, the same as with the kernels.

Regards,
Andreas

Right,

spacecmd system_listupgrades actually uses the system.listLatestUpgradablePackages API.
Output of this API you can check on your spacewalk at
/rhn/apidoc/handlers/SystemHandler.jsp#listLatestUpgradablePackages

basically for every installed server package, that can be upgraded following structure is returned:

string "name"
string "arch"
string "from_version"
string "from_release"
string "from_epoch"
string "to_version"
string "to_release"
string "to_epoch"
string "to_package_id"

so you see for every upgradable package the latest package to that you may upgrade.

What spacecmd system_listupgrades actually does is it returns a package list just according to "to_package_id".
So if you have multiple kernel versions installed, for all the older ones the latest kernel is offered as an
update, what causes the kernel package is listed several times.

An option would be just to remove duplicates from the list.
