Richard Purdie d842d2507a bitbake: runqueue: Fix next_buildable_task performance problem
Looking at the profile information, a lot of time is being spent in
next_buildable_task. This is probably due to the generator expressions
not working well with the empty test.

The easiest way to improve things is to switch to using set manipulations.
We also don't need to update self.buildable the way the original code did
as we don't rely on that anywhere.

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
