Description Daniel Mach 2018-04-20 08:50:53 UTC
libdnf will need a way how to decompress files from repodata.

primary, filelists and others are handled by libsolv -> they are out of scope

We'll need to decompress modules.yaml[.gz] and possibly also comps
and handle them in libdnf by ourselves.

Existing DNF function lives here:
dnf / yum / misc.py / decompress()

I'm thinking about a class:
Decompressor(path)
  - toString() - return decompressed data
  - toFile(path) - write to a file
  - we may consider decompressing to a C++ stream, but I'd probably avoid doing it before it's needed

The new code probably belongs under libdnf/utils.

No, it doesn't need this. Just use solv_xfopen() and it will handle everything for you.

This bug appears to have been reported against 'rawhide' during the Fedora 29 development cycle.
Changing version to '29'.

I believe we have implemented this in this PR:
