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
|
|
|

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
