In multiconfig builds with large numbers of identical tasks, builds were deadlocking after recent runqueue changes upon rebuilds where there was heavy sstate usage (i.e. on second builds after a first completed). The issue was that deferred tasks were being left indefinitely on the deferred list. The deadlock handler was then "breaking" things by failing tasks that had already succeeded, leading to the task being on both covered and not covered lists, giving a further error. The fix is to clean up the deferred task list when each setscene task completes. I'd previously been hoping to avoid iterating that list but it appears unavoidable.

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: https://docs.yoctoproject.org
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
