# How to Contribute to Abseil
|
|
|
|
We'd love to accept your patches and contributions to this project. There are
|
|
just a few small guidelines you need to follow.
|
|
|
|
NOTE: If you are new to GitHub, please start by reading [Pull Request
|
|
howto](https://help.github.com/articles/about-pull-requests/)
|
|
|
|
## Contributor License Agreement
|
|
|
|
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.
|
|
|
|
## Coding Style
|
|
|
|
To keep the source consistent, readable, diffable and easy to merge, we use a
|
|
fairly rigid coding style, as defined by the
|
|
[google-styleguide](https://github.com/google/styleguide) project. All patches
|
|
will be expected to conform to the style outlined
|
|
[here](https://google.github.io/styleguide/cppguide.html).
|
|
|
|
## Guidelines for Pull Requests
|
|
|
|
* If you are a Googler, it is preferable to first create an internal CL and
|
|
have it reviewed and submitted. The code propagation process will deliver
|
|
the change to GitHub.
|
|
|
|
* Create **small PRs** that are narrowly focused on **addressing a single
|
|
concern**. We often receive PRs that are trying to fix several things at a
|
|
time, but if only one fix is considered acceptable, nothing gets merged and
|
|
both author's & review's time is wasted. Create more PRs to address
|
|
different concerns and everyone will be happy.
|
|
|
|
* For speculative changes, consider opening an [Abseil
|
|
issue](https://github.com/abseil/abseil-cpp/issues) and discussing it first.
|
|
If you are suggesting a behavioral or API change, consider starting with an
|
|
[Abseil proposal template](ABSEIL_ISSUE_TEMPLATE.md).
|
|
|
|
* Provide a good **PR description** as a record of **what** change is being
|
|
made and **why** it was made. Link to a GitHub issue if it exists.
|
|
|
|
* Don't fix code style and formatting unless you are already changing that
|
|
line to address an issue. Formatting of modified lines may be done using
|
|
`git clang-format`. PRs with irrelevant changes won't be merged. If
|
|
you do want to fix formatting or style, do that in a separate PR.
|
|
|
|
* Unless your PR is trivial, you should expect there will be reviewer comments
|
|
that you'll need to address before merging. We expect you to be reasonably
|
|
responsive to those comments, otherwise the PR will be closed after 2-3
|
|
weeks of inactivity.
|
|
|
|
* Maintain **clean commit history** and use **meaningful commit messages**.
|
|
PRs with messy commit history are difficult to review and won't be merged.
|
|
Use `rebase -i upstream/master` to curate your commit history and/or to
|
|
bring in latest changes from master (but avoid rebasing in the middle of a
|
|
code review).
|
|
|
|
* Keep your PR up to date with upstream/master (if there are merge conflicts,
|
|
we can't really merge your change).
|
|
|
|
* **All tests need to be passing** before your change can be merged. We
|
|
recommend you **run tests locally** (see below)
|
|
|
|
* Exceptions to the rules can be made if there's a compelling reason for doing
|
|
so. That is - the rules are here to serve us, not the other way around, and
|
|
the rules need to be serving their intended purpose to be valuable.
|
|
|
|
* All submissions, including submissions by project members, require review.
|
|
|
|
## Running Tests
|
|
|
|
Use "bazel test <>" functionality to run the unit tests.
|
|
|
|
Prerequisites for building and running tests are listed in
|
|
[README.md](README.md)
|
|
|
|
## Abseil Committers
|
|
|
|
The current members of the Abseil engineering team are the only committers at
|
|
present.
|
|
|
|
## Release Process
|
|
|
|
Abseil lives at head, where latest-and-greatest code can be found.
