Currently the cache can grow huge since any previously used hash is retained in the cache. This change moves to use one hash per task which improves the speed of the functions considerably. Currently performance is an issue, as are very large cache files and cache load time. By moving to a single hash per task, the shorted filename as a key is no longer usable as the same recipe has multiple variants for the same filename so this has to change.

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:

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
