Hi list, Say a package has a dependency for libfoo.so.1, and 2 (or more) packages provide libfoo.so.1, how does yum decide which package to install to meet the dependency?

Fix for https://bugzilla.redhat.com/show_bug.cgi?id=1266918

...#39;, then both 'nss' and 'palemoon' are added to the package list. Yum used to handle this differently - it used to only pick the package with the shortest name. Later on, before yum was retired, it had a more complex decision algorithm described here: http://yum.baseurl.org/wiki/CompareProviders This change makes supermin use the shortest name algorithm, so in the case above, it always picks 'nss' over 'palemoon'. There is a second possible problem which is not fixed by the current patch set: If a package both provides and requires the same dependency, we should ignore...

This is v2 of the 4/4 patch from the original series. Changes: - memoize the function this time - check packages are installed using rpm_package_of_string However I didn't combine the two case together, because the code is a bit simpler with them separate. Rich.
