bitbake-getvar does not have a way to silence bitbake server's logger and that makes the tool hard to use for text processing. This is especially true when one wants to get a bitbake value to be piped to some other utility and instead we get uncontrolled logging messages or warnings together with bitbake's variable value. Example without quiet: bitbake-getvar --value MACHINE NOTE: Starting bitbake server... qemux86-64 With quiet: bitbake-getvar --value MACHINE --quiet qemux86-64 (Bitbake rev: d677daa0770c66010fc4ed0af5bbbb94752ba590) Signed-off-by: Paulo Neves <ptsneves@gmail.com> Signed-off-by: Alexandre Belloni <alexandre.belloni@bootlin.com> (cherry picked from commit af354e975d0b4c26d0e91e3c82946b093bc11b45) Signed-off-by: Markus Niebel <Markus.Niebel@ew.tq-group.com> Signed-off-by: Steve Sakoman <steve@sakoman.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org> Signed-off-by: Steve Sakoman <steve@sakoman.com>
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: https://www.openembedded.org/
Bitbake plain documentation can be found under the doc directory or its integrated html version at the Yocto Project website: https://docs.yoctoproject.org
Contributing
Please refer to https://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

Testing:
Bitbake has a testsuite located in lib/bb/tests/ whichs aim to try and prevent regressions. You can run this with "bitbake-selftest". In particular the fetcher is well covered since it has so many corner cases. The datastore has many tests too. Testing with the testsuite is recommended before submitting patches, particularly to the fetcher and datastore. We also appreciate new test cases and may require them for more obscure issues.
