multiarch support

[KostyaSha]

Does libsolv support multiarches for dependencies calculation?
I think it should look like primary arch + additional arch, if packages exist in primary, then additional ignored. If package has dot arch, then keep additional arch.

Yes, it can deal with multiple architectures. If you mean the "Fedora" way, where multiple packages with the same name (but different architectures) can be installed in parallel, things get a bit trickier. It can also deal with that, but you have to set the POOL_FLAG_OBSOLETEUSESCOLORS flag (but that's the default if FEDORA is defined when libsolv is built).

If the question is about OBS, which just uses libsolv as storage format and package query interface, the answer is a bit different. There's currently no good way for having multiple packages with the same name but different architectures in the :full tree, so you're out of luck. This will change when I redo the :full management in the next weeks, though.
