Problems with Yum and Arch/Noarch Packages

The yum tool as shipped in Fedora 11 will choose an arch-specific package over a "later" arch-independent package - Bug #502401. This is a bit of a blow for those of us trying to move ahead with Features/NoarchSubpackages and it's been closed UPSTREAM and not fixed in Fedora (a pet hate of mine). So I built the Rawhide version of yum (which contains the fix) for F-11 and stuck it in my local repository. This allowed me to build the perl-IO-Zlib update today (the package has build requirements that have changed from arch-specific to arch-independent, and F-11's yum was selecting the arch-specific version, which was too old for perl-IO-Zlib).

Using this update was not without its consequences. My custom repocheck script (a modified version of repoclosure) broke: 

Running: repocheck --config=/home/paul/lib/repoc-rhel5-i386.conf --newest --checkrepo city-fan.org-rhel5-i386
Traceback (most recent call last):
  File "/home/paul/bin/repocheck", line 258, in <module>
    main()
  File "/home/paul/bin/repocheck", line 158, in main
    my = RepoClosure(arch = opts.arch, config = opts.config, builddeps = opts.builddeps)
  File "/home/paul/bin/repocheck", line 69, in __init__
    self.doConfigSetup(fn = config,init_plugins=False)
  File "/usr/lib/python2.6/site-packages/yum/__init__.py", line 168, in doConfigSetup
    return self.conf

    conf = property(fget=lambda self: self._getConfig(),
  File "/usr/lib/python2.6/site-packages/yum/__init__.py", line 210, in _getConfig
    arch = self.arch.canonarch
AttributeError: 'list' object has no attribute 'canonarch'

Now I don't know much python but after a bit of googling around and looking at the code, I made these changes, which seemed to fix things:

Fedora Project

  • Updated gtkwave for F-11 and Rawhide to resolve Bug #511858, an easily-reproducible crash when trying to use Print to File

  • Looking through fedora-perl-devel-list, I noticed a bunch of FTBFS (Fails To Build Build From Source) bugs had been raised. I didn't have time to look through many of them, but I noticed that the perl-Template-Plugin-Class failure had also been reported upstream and that a new version 0.14 had been issued, removing the bogus test that had triggered the failure. So I updated perl-Template-Plugin-Class and closed Bug #511438 accordingly.

Local Packages

  • Updated gtkwave as per the Fedora version

  • Updated perl-IO-Zlib to 1.10 (no functional changes)
