There was a weird error in OE-Core where "devtool modify virtual/kernel" was showing basehash mismatch errors. This was due to SRCPV sometimes being: AUTOINC+b867b78b50_47b80ef7bd and sometimes AUTOINC+b867b78b50_255a750d28. The latter hash comes from KBRANCH and meant sometimes the correct branch was seen, sometimes it was not. The issue was complicated by the execution using a remote datastore over tinfoil. The problem turns out to be a fetcher caching error. If the datastore changes, the cached url data may not be valid. We therefore ensure we match cached url data against the datastore that generated it, which appears to fix this issue.

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
