@ignatenkobrain When trying to bring this over to fedmod, I'm getting AttributeError: 'Pool' object has no attribute 'matchdepid' for the new whatprovides helper function.

We also don't use print_transaction in fedmod in general - it's purely for logging purposes, and the CLI and test suite normally run without comprehensive logging enabled.

@ncoghlan you need to have latest libsolv... That function is reference how to analyze dependency tree (in your case to generate information what depends on what).

@ignatenkobrain Do you know if the latest libsolv is going to be submitted as an update to F26? I don't think we should drop F26 support yet, but require folks to have the latest versions of packages there would be fine.

@ncoghlan when it will be released (this month or beginning of next most likely), I don't like putting git snapshots to stable branches.

@ignatenkobrain OK, cool - I've updated the issue text to note that we'll need to wait for a new libsolv release before pursuing this further.

AFAIK we have the required new libsolv in F28, so this can be implemented.
