bitbake: runqueue: Fix setscene hard dependency problems
Commit c54e738e2b5dc0d8e6fd8e93b284ed96e7a83051 added in the idea of hard dependencies such as the case a setscene has a hard dependency on pseudo-native and that dependency wasn't available from sstate for some reason. Unfortunately the implementation was a bit too enthusiastic, causing rebuilds of things when it wasn't necessary. A test case was: bitbake quilt-native bitbake quilt-native -c clean bitbake <some-image> and then you'd watch quilt-native get rebuilt for no good reason. The clue to the problem is in the for loop where it never depends on the item being iterated over. The fix is to include the exact list of hard dependencies rather than guessing. With these changes, the use case above works, the one in the original commit also works. This patch also adds in or cleans up various pieces of logging to allow issues like this to be more easily debugged in future. (Bitbake rev: 81bd475585ff1b44b390036b1eca0feae7c149eb) Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
