It was reported that a race condition on a shared download directory could occur with the gitsm fetcher, the result happened with a call to git config that occured within the update_submodules. Since the fetch is locked by the upper level, it was probably the prior need_update(...) function causing this because of some old code. The gitsm class inherits the git class. The need_update was overridding the version in gitsm, so that it forceably checked the submodules. It's clear we can optimize the code by only updating if the primary repository needs updating. Since we don't care if the submodule repository has changed because if the primary hasn't, references to the submodule won't 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: 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
