BB_GIT_SHALLOW_EXTRA_REFS can include wildcard entries. Matching refs advertised by the remote are later passed to git fetch and update-ref while creating shallow tarballs. Quote the generated command arguments and pass the fetched ref after -- so shell metacharacters and option-like ref names are not interpreted as command syntax or git fetch options. (Bitbake rev: 6d3f8bd4ddc955b49eaa124e0724ea589da30646) Signed-off-by: Anders Heimer <anders.heimer@est.tech> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org> (cherry picked from commit e9a06f79d9ec767c9d95470be78b006d6fd0d59c) [YC: Only the quote part of the master patch applies. The "--" part does not. This part is handled by bin/git-make-shallow which only pass arguments to git rev-list and rev-parse through arrays] Signed-off-by: Yoann Congal <yoann.congal@smile.fr> Signed-off-by: Paul Barker <paul@pbarker.dev>
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
