Bug 35895 – qpkg doesn't handle renamed packages correctly

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Paul Varner (RETIRED) 2003-12-15 13:50:07 UTC]

Recently, several packages have been renamed in Portage.  When using qpkg, qpkg uses the name of the package when installed.  This causes problems when using qpkg for various tasks, .  One such package is apps-admin/fam.  Until recently it was apps-admin/fam-oss.  This can cause confusion when using qpkg to identify packages.

Example:
beldin root # qpkg -I -v fam
app-admin/fam-oss-2.6.10-r1 *
media-libs/libfame-0.9.0 *
beldin root # etcat -v fam-oss
[ Results for search key : fam-oss ]
[ Applications found : 0 ]

beldin root # emerge -pv fam-oss

These are the packages that I would merge, in order:

Calculating dependencies
emerge: there are no masked or unmasked ebuilds to satisfy "fam-oss".

!!! Error calculating dependencies. Please correct.

The cause of this problem is that qpkg takes the name from the ebuild file located in /var/db/pkg/<group>/<package>

Since /var/db/pkg/<group>/<package> is the correct name of the package as it is currently known in the portage system.  The solution is to use that as the name when locating installed packages. Here is the ouput using my patched version:

beldin root # qpkg -I -v fam
app-admin/fam-2.6.10-r1 *
media-libs/libfame-0.9.0 *
beldin root # etcat -u fam
[ Colour Code : set unset ]
[ Legend      : (U) Col 1 - Current USE flags        ]
[             : (I) Col 2 - Installed With USE flags ]
[ No USE flags found for : app-admin/fam ]
[ No USE flags found for : media-libs/libfame ]

 U I [ Found these USE variables in : media-video/fame-0.9.0 ]
 + - mmx : Adds support for optimizations for Pentium MMX and Athlon class processors
 + - sse : fast floating point optimisation for Pentium class chips
beldin root # emerge -pv fam

These are the packages that I would merge, in order:

Calculating dependencies ...done!
[ebuild   R   ] app-admin/fam-2.6.10-r1

beldin root #

I am including a patch that fixes this problem using that approach

Reproducible: Always
Steps to Reproduce:
1. See details.  Another package that exhibits the same behavior is vixie-cron which was known as vcron
2.
3.

Actual Results:  
qpkg lists package names that are unknown to portage.

Expected Results:  
List the package name as currently known to portage

Updated patch

updated patch to fix bug with patched version. I missed setting the 'd'
variable correctly in the first version of the patch.

Updated patch

I'm finding more problems with this approach. This is actually beginning to
look like something that should be addressed with portage-ng

updated patch to list current package name

Stepping back and reevaluating, I realized that I was trying to fix much more
than needed to be touched.  The actual solution was simple, and I am including
that patch. I have tested it with all of the options and it appears to be
working correctly.

[Comment 5 Paul Varner (RETIRED) 2004-01-09 08:55:27 UTC]

Since this is fixed with equery (qpkg's replacement) in gentoolkit 0.2.0, I'm marking this as fixed.
