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
Bitbake requires Python version 3.8 or newer.
Contributing
------------
Please refer to our contributor guide here: https://docs.yoctoproject.org/contributor-guide/
for full details on how to submit changes.
As a quick guide, patches should be sent to bitbake-devel@lists.openembedded.org
The git command to do that would be:
git send-email -M -1 --to bitbake-devel@lists.openembedded.org
If you're sending a patch related to the BitBake manual, make sure you copy
the Yocto Project documentation mailing list:
git send-email -M -1 --to bitbake-devel@lists.openembedded.org --cc docs@lists.yoctoproject.org
Mailing list:

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.
To run the tests "zstd" and "git" must be installed.
The assumption is made that this testsuite is run from an initialized OpenEmbedded build
environment (i.e. `source oe-init-build-env` is used). If this is not the case, run the
testsuite as follows:
export PATH=$(pwd)/bin:$PATH
bin/bitbake-selftest
The testsuite can alternatively be executed using pytest, e.g. obtained from PyPI (in this
case, the PATH is configured automatically):
pytest
