In a multiconfig situation there are circumstances where firstly, tasks are deferred when they shouldn't be, then later, tasks can end up as both covered and not covered. This patch fixes two related issues. Firstly, the stamp validity checking is done up front in the build and not reevaulated. When rebuilding the deferred task list after scenequeue hash change updates, we need therefore need to check if a task was in notcovered *or* covered when deciding to defer it. This avoids strange logs like: NOTE: Running setscene task X of Y (mc:initrfs_guest:/A/alsa-state.bb:do_deploy_source_date_epoch_setscene) NOTE: Deferring mc:initrfs_guest:/A/alsa-state.bb:do_deploy_source_date_epoch after mc:host:/A/alsa-state.bb:do_deploy_source_date_epoch where tasks have run but are then deferred. Since we're recalculating the whole list, we also need to clear it before iterating to rebuild it. By ensuring covered tasks aren't added to the deferred queue, the covered + notcovered issue should also be avoided. in the task deadlock forcing code.

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
