stop using repo2solv #534

Open dcermak opened 5 months ago

dcermak commented 5 months ago

libzypp depends on libsolv-tools due to a single line of code where repo2solv is invoked: https://github.com/openSUSE/libzypp/blob/fb7deafb939552116b7677007305e2ea0d28bdd1/zypp/RepoManager.cc#L452

Would it be possible to drop this external call and use parts of libsolv directly? I know that https://github.com/openSUSE/libsolv/blob/master/tools/repo2solv.c is not exactly small, but maybe not all of its functionality is absolutely required?

This would allow us to make our containers a bit smaller by dropping the libsolv-tools dependency entirely.

Since we are currently rewriting code to be executed async we'd need to build our own repo2solv binary ( libsolv has no thread support )... which probably would not be smaller than the one we are currently shipping..

bzeller commented 5 months ago

Once we are there we can try and build a binary that only does what we want and links libsolv directly and see if its smaller.

We're currently using repo2solv and rpmdb2solv. And we wan't dumpsolv to be available on the system. (we may depend on mergesolv in the future)

Maybe @mlschroe likes to split a few things into a basic libsolv-tools and move the stuff also covered by repo2solv into an extra package (updateinfoxml2solv, susetags2solv, rpmmd2solv, rpms2solv, helix2solv, deltainfoxml2solv..)

libsolv could also expose those features as library function
