## Guidelines for Pull Requests
How to get your contributions merged smoothly and quickly:
Please read the following carefully to ensure your contributions can be merged
smoothly and quickly.
### PR Contents
- Create **small PRs** that are narrowly focused on **addressing a single
concern**. We often receive PRs that attempt to fix several things at the same
time, and if one part of the PR has a problem, that will hold up the entire
PR.
- For **speculative changes**, consider opening an issue and discussing it
first. If you are suggesting a behavioral or API change, consider starting
with a [gRFC proposal](https://github.com/grpc/proposal). Many new features
that are not bug fixes will require cross-language agreement.
- If your change does not address an **open issue** with an **agreed
resolution**, consider opening an issue and discussing it first. If you are
suggesting a behavioral or API change, consider starting with a [gRFC
proposal](https://github.com/grpc/proposal). Many new features that are not
bug fixes will require cross-language agreement.
- If you want to fix **formatting or style**, consider whether your changes are
an obvious improvement or might be considered a personal preference. If a

often written as "iff". Please do not make spelling correction changes unless
you are certain they are misspellings.
- 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.
- Maintain a **clean commit history** and use **meaningful commit messages**.
PRs with messy commit histories are difficult to review and won't be merged.
Before sending your PR, ensure your changes are based on top of the latest
`upstream/master` commits, and avoid rebasing in the middle of a code review.
You should **never use `git push -f`** unless absolutely necessary during a
review, as it can interfere with GitHub's tracking of comments.
- **All tests need to be passing** before your change can be merged. We
recommend you run tests locally before creating your PR to catch breakages

GitHub, which will trigger a GitHub Actions run that you can use to verify
everything is passing.
- If you are adding a new file, make sure it has the **copyright message**
- Note that there are two github actions checks that need not be green:
1. We test the freshness of the generated proto code we maintain via the
`vet-proto` check. If the source proto files are updated, but our repo is
not updated, an optional checker will fail. This will be fixed by our team
in a separate PR and will not prevent the merge of your PR.
2. We run a checker that will fail if there is any change in dependencies of
an exported package via the `dependencies` check. If new dependencies are
added that are not appropriate, we may not accept your PR (see below).
- If you are adding a **new file**, make sure it has the **copyright message**
template at the top as a comment. You can copy the message from an existing
file and update the year.
- The grpc package should only depend on standard Go packages and a small number
of exceptions. **If your contribution introduces new dependencies**, you will
need a discussion with gRPC-Go maintainers. A GitHub action check will run on
every PR, and will flag any transitive dependency changes from any public
package.
need a discussion with gRPC-Go maintainers.
### PR Descriptions
- **PR titles** should start with the name of the component being addressed, or
the type of change. Examples: transport, client, server, round_robin, xds,
cleanup, deps.
- Read and follow the **guidelines for PR titles and descriptions** here:
https://google.github.io/eng-practices/review/developer/cl-descriptions.html
*particularly* the sections "First Line" and "Body is Informative".
Note: your PR description will be used as the git commit message in a
squash-and-merge if your PR is approved. We may make changes to this as
necessary.
- **Does this PR relate to an open issue?** On the first line, please use the
tag `Fixes #<issue>` to ensure the issue is closed when the PR is merged. Or
use `Updates #<issue>` if the PR is related to an open issue, but does not fix
it. Consider filing an issue if one does not already exist.
- PR descriptions *must* conclude with **release notes** as follows:
```
RELEASE NOTES:
* <component>: <summary>
```
This need not match the PR title.
The summary must:
* be something that gRPC users will understand.
* clearly explain the feature being added, the issue being fixed, or the
behavior being changed, etc. If fixing a bug, be clear about how the bug
can be triggered by an end-user.
* begin with a capital letter and use complete sentences.
* be as short as possible to describe the change being made.
If a PR is *not* end-user visible -- e.g. a cleanup, testing change, or
github-related, use `RELEASE NOTES: n/a`.
### PR Process
- Please **self-review** your code changes before sending your PR. This will
prevent simple, obvious errors from causing delays.
- Maintain a **clean commit history** and use **meaningful commit messages**.
PRs with messy commit histories are difficult to review and won't be merged.
Before sending your PR, ensure your changes are based on top of the latest

- Unless your PR is trivial, you should **expect reviewer comments** that you
will need to address before merging. We'll label the PR as `Status: Requires
