The following code costs a lot of time when there are lot of layers and recipes:
for collection in collections:
collection_res[collection] = d.getVar('BBFILE_PATTERN_%s' % collection) or ''
My build has more than 100 layers and 3000 recipes, which calls d.getVar() 300K
(3000 * 100) times and makes 'bitbake-layers show-recipes' very slow, add a
keyword argument to get_file_layer() can fix the problem, it can save about 90%
time in my build (6min -> 40s).

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
