Subject: [PATCH] hawkey.subject: get_best_selectors only obsoleters of latest
In situation where a package exists in multiple versions and some older
version is being obsoleted, any of obsoleters was considered a valid
solution.
The result could be really misleading. For example let's have this package set:
systemd-udev-1.0
systemd-udev-2.0
Obsoletes: systemd-udev < 2
systemd-boot-unsigned-2.0
Obsoletes: systemd-udev < 2
In this case `dnf install systemd-udev` may lead to installation of
systemd-boot-unsigned which is probably not what the user expected. The
reason is the split in the upgrade-path created by obsolete and both
branches - systemd-udev-2.0 and systemd-boot-unsigned-2.0 are considered
valid.
With this patch install command takes into account only obsoleters of
the best version of the package so the `dnf install systemd-udev`
results in correct installation of systemd-udev-2.0 package.
