Description Paul Eggleton 2014-10-24 16:51:40 UTC 
oe.utils.both_contain() just does a find() on the value rather than splitting the value and then looking in the list of split items. The result is that if you add a feature to MACHINE_FEATURES that itself has a substring that matches one of the values looked for when building COMBINED_FEATURES, you end up with an incomprehensible error (here with "ext2i" in MACHINE_FEATURES):

ERROR: Nothing RPROVIDES 'packagegroup-base-ext2' (but /home/balister/src/oe-core/oe-core/meta/recipes-core/packagegroups/packagegroup-base.bb RDEPENDS on or otherwise requires it)

Investigation started.
Comment 2 Cristian Iorga 2015-02-25 15:29:56 UTC 
oe.utils.both_contain() will be reimplemented similar to bb.utils.contains().
