creenshot - incorrectly showing the contents of the 'Red Hat Enterprise Supplementary' group

Just to clarify - "Red Hat Enterprise Linux Supplementary" is the category.  Within that category the following groups should be available:

java-base
java-database
java-browser
misc
multimedia
virtualization
zhongyi-song-fonts

The lack of a triangle next to "Red Hat Enterprise Linux Supplementary" in the UI indicates to me that it's not finding any of these groups.

I can reproduce this bug with your link, thanks. I'll investigate now.

simple yum test program

I've traced PackageKit, and it seems to work as expected. I've attached a simple yum script that seems to also fail.

output of the simple test program

This shows the missing group information for the 'Supplementary' category.

Looking at the comps xml manually, it seems to look correct, so I'll re-assign to the yum guys to see if anything is broken when parsing the comps data.

Dennis, James
the comps file you reference has

    <grouplist>
      <groupid>java-base</groupid>
      <groupid>java-browser</groupid>
      <groupid>java-database</groupid>
      <groupid>misc</groupid>
      <groupid>multimedia</groupid>
      <groupid>zhongyi-song-fonts</groupid>
    </grouplist>


you'll notice 'virtualization' is absent there.

but in the x86_64 comps file from the same path

virtualization is present.

are the x86_64  and i386 comps files supposed to be different here?

That is intentional.  The virtualization packages are only delivered in the x86_64 Supplementary tree.  As part of the compose process, we filter out comps groups that are empty for that tree.

Here's some simple code to see if yum can see the groups in the category:

import yum
my = yum.YumBase()
for cat in my.comps.get_categories():
   if cat.categoryid == 'supplementary':
       print cat.categoryid
       for g in cat.groups:
           print '  %s' % g


when I run it on el6b<mumble> I get

supplementary
  multimedia
  java-base
  java-database
  misc
  java-browser
  virtualization
  zhongyi-song-fonts

that's on x86_64

Seth,

Using 'comps.get_groups(cat.categoryid)' I get 5 groups for the supplementary category.

Using 'cat.groups' I get 7 groups, the other entries being "misc" and "multimedia".

How come the data is different? Which method should I be using in PackageKit? Thanks.

 This is not a yum API. The yum API is:

    def get_groups(self):

...what you are calling comes from:

PackageKit/backends/yum/yumComps.py
[...]
class yumComps:
[...]
    def get_groups(self, cat_id):

...which appears to be an sqlite/caching layer, but (of course) in PK only.

> ...which appears to be an sqlite/caching layer, but (of course) in PK only.

Of course, sorry -- my mistake. The reason for the missing groups was that there were no mandatory, default or optional packages in the "misc" and "multimedia" groups, and so PK ignored them. PK only shows users a simpler kind of meta-package for groups, and hence simplifies things a bit.

I fear the real bug is that PK needs to call comps.refresh() after adding a repo or enabling a repository. You can test this by enabling the supplementary repo, and then doing "pkcon refresh-cache" on the command line.

What's the usual use-case of somebody using the supplementary repo? Do they install a foo-release.rpm file or just add a repo file?

My understanding is that the customer either does everything through RHN (meaning they subscribe to the supplementary channel), or they insert a Supplementary CD into the system.  Then they launch gpk-application and install the desired software.

I just tested this workaround (well, 'pkcon refresh'), but after running that, the Supplementary groups appeared in gpk-application
