It is beyond my time and energy to "fight" bad package updates that don't
fix the problem:
What the new createrepo_c in that update does, it ignores the broken
Requires altogether, skips it and doesn't add it to the repo metadata .
Effectively, it hides the problem even more than before when it replaced
the unescaped RPM macro with a '0', changing the dependency on-the-fly,
pretending that there is no problem when in fact it's broken in the binary
package that cannot be installed.
Hiding such breakage from the metadata hides it also from depsolvers and
tools like repoclosure that work on the metadata themselves before passing
a transaction to RPM. They would _not_ be able to find such a problem.
IMHO, this is bad as before. I cannot estimate how often an unescaped
epoch macro will break deps in the future again, but a package like that
should not be published with repo metadata pretending that everything
would be fine. If you fear that createrepo_c exiting with error condition
*instead* would happen too often, then apparently the problem is perceived
as an even worse one. Hard to believe.
