The reason for this should be recorded in the commit logs. Imagine you have a target recipe (e.g. meta-extsdk-toolchain) which depends on gdb-cross. sstate in OE-Core allows gdb-cross to have the same hash regardless of whether its built on x86 or arm. The outhash will be different. We need hashequiv to be able to adapt to the prescence of sstate artefacts for meta-extsdk-toolchain and allow the hashes to re-intersect, rather than trying to force a rebuild of meta-extsdk-toolchain. By this point in the build, it would have already been installed from sstate so the build needs to adapt. Equivalent hashes should be reported to the server as a taskhash that needs to map to an specific unihash. This patch adds API to the hashserv client/server to allow this.

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
