We were testing the validity of deferred tasks setscene status "up front" which is very unlikely to succeed and leads to cache invalidation issues. With the change to rebuild the deferred task list, this status becomes out of sync. The result was tasks being executed when they should not have been leading to extra work for the build unnecessarily. Instead, don't process validity status for deferred tasks and assume their data will become available. If it doesn't, this will now result in a build error as the setscene task will fail and the main task will run instead. In theory we could try and track the state changes in the deferred list and re-test validity then but I'm not sure it is worth the effort when the other code path and errors in setscene tasks will give a pretty good idea of what is happening anyway.

Bitbake
BitBake is a generic task execution engine that allows shell and Python tasks to be run efficiently and in parallel while working within complex inter-task dependency constraints. One of BitBake's main users, OpenEmbedded, takes this core and builds embedded Linux software stacks using a task-oriented approach.
For information about Bitbake, see the OpenEmbedded website: http://www.openembedded.org/
Bitbake plain documentation can be found under the doc directory or its integrated html version at the Yocto Project website: http://yoctoproject.org/documentation
Contributing
Please refer to http://www.openembedded.org/wiki/How_to_submit_a_patch_to_OpenEmbedded for guidelines on how to submit patches, just note that the latter documentation is intended for OpenEmbedded (and its core) not bitbake patches (bitbake-devel@lists.openembedded.org) but in general main guidelines apply. Once the commit(s) have been created, the way to send the patch is through git-send-email. For example, to send the last commit (HEAD) on current branch, type:
git send-email -M -1 --to bitbake-devel@lists.openembedded.org
