Description Tom Horsley 2013-07-04 08:54:16 EDT
Description of problem:

I saw this a lot on f19 beta and attributed it to random beta repo problems, but now I've done a distro-sync and started getting "official" fedora 19 updates and the problem persists. Here's the latest example:

[root@zooty ~]# yum clean packages
Loaded plugins: afteryum, fastestmirror, langpacks, refresh-packagekit
Cleaning repos: fedora google-chrome rpmfusion-free rpmfusion-free-updates
              : rpmfusion-nonfree rpmfusion-nonfree-updates updates
14 package files removed

Note that every one of the does not match failures were for a 32 bit rpm
(several of which are installed on my 64 bit system). It is almost as if it is attempting to apply 64 bit deltas to 32 bit rpms.

Also note that it apparently fails to cleanup after itself when it has to download real rpms as the "yum clean packages" says it removed the exact same number of files as it had to download.

I seem to get a few of these failures on every yum update that I run (always some different set of random packages that fail).

Version-Release number of selected component (if applicable):
I was probably running yum-3.4.3-95.fc19.noarch when I got those messages and the update installed yum-3.4.3-99.fc19.noarch

How reproducible:
I always seem to get a few of these every time.

Steps to Reproduce:
1.see above

Actual results:
deltas that don't match, time wasted downloading the useless delta then downloading the full rpm instead.

Expected results:
deltas that match.

Comment 1 Frank McCormick 2013-07-04 09:31:22 EDT
Much the same thing has been happening here. The difference is I am running 32 bit Fedora, not 64 bit.
I haven't checked whether Yum clean packages does the same thing as I usually run
yum clean all and never noticed what was being cleaned up.
It's a mystery to me - never could understand why disk files didn't match, as unlike my Debian Sid installation, there is no "locale cleanup" facility available in Fedora. (not to my knowledge anyway).

Pass arch of package to applydeltarpm

The problem is that the drpm format doesn't natively store the arch of the old package, so we have to pass it to applydeltarpm using the -a flag.

The attached patch should fix the problem.
Comment 3 Tom Horsley 2013-07-05 10:21:13 EDT
I just did another update and verified the failure to clean things up.

There were a couple of i686 rpms that failed to match, and the i686.drpm files really were laying around in the cache, but the i686.rpm files it downloaded when the delta didn't match were also laying around in the cache, and I definitely don't have it configured to preserve the downloaded rpms. None of the normally applied x86_64 rpms or drpms were still laying around after the yum update.
