The NPM package.json documentation[1] states that git URLs may contain a commit-ish suffix to specify a specific revision. When running `npm install`, this revision will be looked for on any branch of the repository. The bitbake implementation however translates the URL stored in package.json into a git URL to be fetch by the bitbake git fetcher. The bitbake fetcher git.py, enforces the branch to be master by default. If the revision specified in the package.json is not on the master branch, the fetch will fail while the package.json is valid. To fix this, append the ";nobranch=1" suffix to the revision in the git URL to be fetched. This will make the bitbake git fetcher ignore the branch and respect the behavior of `npm install``. This can be tested with the following command: $ devtool add --npm-dev https://github.com/seapath/cockpit-cluster-dashboard.git -B version Which points to a project which has a package.json with a git URL: ```json "devDependencies": { "cockpit-repo": "git+https://github.com/cockpit-project/cockpit.git#d34cabacb8e5e1e028c7eea3d6e3b606d862b8ac" } ``` In this repo, the specified revision is on the "main" branch, which would fail without this fix.

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
