[bitbake-devel] [PATCH] parse: get_file_depends(): return deterministic result

[Enrico Scholz]

The output of get_file_depends() concatenates elements of a set.  Result
of this operation is not deterministic because it is calculated by
parallel running parsing threads.

Because result of get_file_depends() is stored into BBINCLUDED which
goes in into various hash calculations, this can cause unwanted rebuilds
of cache or recipes.
