Improve install candidate selection
Florian Boor <florian.boor@kernelconcepts.de> Hello, I have noticed that opkg does not resolve package selection properly if the same package is available in more than one compatible architecture. Failing having installable candidates available is not necessary in this case: Either the packages are from feeds with different priorities - in this case we can select by priority - or the priorities are the same and it does not matter which one gets installed. Another problem is that in some situations the package lists seem to contain duplicates for no obvious reason. (e.g. one package available from two feeds makes four entries in the package lists.) The patch implements a workaround for this by filtering out duplicates when the candidate lists are created and makes opkg select an install candidate per feed priority. I have tested the changes with OpenEmbedded and it does not seem to cause any obvious problems. Could I get some opinions about the solution? :) Greetings Florian ----------- Thanks to Florian git-svn-id: http://opkg.googlecode.com/svn/trunk@219 e8e0d7a0-c8d9-11dd-a880-a1081c7ac358
