Thanks James!
We'll get to test the fix tomorrow on our P7 box to see if it works,
will give an update then.
Thanks & regards, Phil
Alright, quick heads up: I ran the tests today and the patch seems to be
working.
From what i understand the following now happens:
Installed: foo-1.i386
Exactarch irrelevant
Commands: yum install foo-1.i686
yum install foo-1.i386 foo-1.i686
yum update foo-1.i686
Result: Same version of pkgs, i386 pkg already installed. Co-install
conflict detected, i686 pkg removed from ts -> Nothing to do, but no error.
Exactarch = true
Commands: yum install foo-2.i686
yum install foo-2.i386 foo-2.i686
yum update foo-2.i686
Result: Update, but exactarch keeps us on i386, so foo-2.i386 is
installed.
Exactarch = false
Commands: yum install foo-2.i686
yum install foo-2.i386 foo-2.i686
yum update foo-2.i686
Result: Update, but exactarch now allows us to transition to "higher"
arch, so update will be foo-2.i686.
I've only really tested the first case as that was the one that was
erroring out (where it shouldn't have) and that works now as expected.
James, could you get a rawhide build of that yum today so we can pull it
into our Fedora 18 ppc64 tree please?
Thanks!
Regards, Phil
