Description Trevor Hemsley 2009-09-28 12:08:08 EDT

Description of problem:
yum check-update ignores the --obsoletes parameter or the obsoletes=1 yum.conf setting.


Version-Release number of selected component (if applicable):
yum-3.2.19-18.el5_3.1

How reproducible:
Every time if an obsoleted package is installed and a newer version is available


Steps to Reproduce:
1. Run yum check-update
2. Examine list of packages to be updated
3. Run yum update

  
Actual results:
Ooops, it includes packages now which obsolete packages that are already installed but were not listed in the check-update output

Expected results:
yum check-update should list packages that will be installed by yum update and not miss them out. i.e. check-update should be the equivalent of the old up2date --dry-run parameter

Additional info:
If /etc/yum.conf contains obsoletes=1 then check-update will give different results than update does. Check-update should be a way of finding out what will be updated on the system if you run a subsequent update and should also honour the --obsoletes switch or obsoletes=1 parameter.

Comment 1 James Antill 2009-09-28 12:49:34 EDT

"yum check-update --verbose" will list obsoletes packages, in the 5.4 version of yum (3.2.22-20) and the last part of the man page about check-update says:

    Running in  verbose  mode  also shows obsoletes.

The obsoletes flag is almost always on, so the cmd line option does nothing (see yum.conf which has obsoletes=1 in it).

Comment 2 Trevor Hemsley 2009-09-29 04:55:36 EDT

This is illogical behaviour and should be fixed. Check-update should do the same as update or there is no point in having it. Check-upate should respect teh same options that update does.

I am running 5.3 as my hosting provider has not rolled out 5.4 yet and man yum says nothing about this. 

What's the point in check-update using a different switch to obtain the same result.

Comment 3 James Antill 2009-09-29 17:13:04 EDT

Fair enough, I've made it output when obsoletes is on now. It'll be changed in 5.5.

Comment 4 Trevor Hemsley 2009-09-30 05:24:10 EDT

Great, I'll look forward to 5.5 then. Thanks.
