The runall commandline option was confusing people. There are in fact two different behaviours people may want. a) For a given target (or set of targets) look through the task graph and run task X only if its present and would have been built. b) For a given target (or set of targets) look through the task graph and run task X if any recipe in the taskgraph has such a target even if it wasn't in the original task graph. I've decided to interpret the existing "runall" option as b), even if right now if behaves like a). For a), which is a valid use case, this patch adds a "runonly" option. With both behaviours present, I'm hoping we can then kill off the "fetchall", "checkuriall" and other tasks from OE metadata and replace them with this option. This would significantly speed up task graph processing. (Deleting the checkuriall and fetchall tasks takes "bitbake core-image-sato -g" from 22s to 8s).

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
