We'd love to accept your patches and contributions to this project. There are just a few small guidelines you need to follow.
Contributions to this project must be accompanied by a Contributor License Agreement. You (or your employer) retain the copyright to your contribution, this simply gives us permission to use and redistribute your contributions as part of the project. Head over to https://cla.developers.google.com/ to see your current agreements on file or to sign a new one.
You generally only need to submit a CLA once, so if you've already submitted one (even if it was for a different project), you probably don't need to do it again.
All submissions, including submissions by project members, require review. We use GitHub pull requests for this purpose. Consult GitHub Help for more information on using pull requests.
Some checked-in files are generated and need to be updated when a new PR is merged.
To regenerate the content under the docs/ directory, run this script in the
repository root:
./update_docs.shThis needs to be done whenever the docstrings in the corresponding .bzl files
are changed; see docs/BUILD.
The packaging rules depend on two precompiled binaries, tools/piptool.par and
tools/whltool.par. We need these to be precompiled because they are invoked
during WORKSPACE evaluation, before Bazel itself is able to build anything
from source. The .par files can be regenerated by running this script in the
repository root:
# You can pass --nodocker if Docker is not available on your system.
./update_tools.shThis needs to be done whenever the corresponding sources in the packaging/
directory are updated.
Since these are binary files and therefore unreviewable, for security reasons1 we will regenerate the .par files for you when merging your pull request.
