## Considerations Before Sending Your First PR
## External Contributors

When contributing to the codebase, please note:

- Make sure to follow the [Commit, Issue & PR guidelines](#commit-issue--pr-guidelines)
- Non-trivial PRs will not be accepted without tests (see above).
- Please do not bump version numbers yourself.
- [`raven-js`](https://github.com/getsentry/sentry-javascript/tree/3.x/packages/raven-js) and
[`raven-node`](https://github.com/getsentry/sentry-javascript/tree/3.x/packages/raven-node) are deprecated, and only
bug and security fix PRs will be accepted targeting the
[3.x branch](https://github.com/getsentry/sentry-javascript/tree/3.x). Any new features and improvements should be to
our new SDKs (`browser`, `node`, and framework-specific packages like `react` and `nextjs`) and the packages which
support them (`core`, `utils`, `integrations`, and the like).

## PR reviews

For feedback in PRs, we use the [LOGAF scale](https://blog.danlew.net/2020/04/15/the-logaf-scale/) to specify how
important a comment is:

- `l`: low - nitpick. You may address this comment, but you don't have to.
- `m`: medium - normal comment. Worth addressing and fixing.
- `h`: high - Very important. We must not merge this PR without addressing this issue.
We highly appreciate external contributions to the SDK. If you want to contribute something, you can just open a PR
against `develop`.

You only need one approval from a maintainer to be able to merge. For some PRs, asking specific or multiple people for
review might be adequate.
The SDK team will check out your PR shortly!

Our different types of reviews:
When contributing to the codebase, please note:

1. **LGTM without any comments.** You can merge immediately.
2. **LGTM with low and medium comments.** The reviewer trusts you to resolve these comments yourself, and you don't need
to wait for another approval.
3. **Only comments.** You must address all the comments and need another review until you merge.
4. **Request changes.** Only use if something critical is in the PR that absolutely must be addressed. We usually use
`h` comments for that. When someone requests changes, the same person must approve the changes to allow merging. Use
this sparingly.
- Make sure to follow the [Commit, Issue & PR guidelines](./docs/commit-issue-pr-guidelines.md)
- Non-trivial PRs will not be accepted without tests (see above).

## Commit, Issue & PR guidelines

### Commits

For commit messages, we use the format:

```
<type>(<scope>): <subject> (<github-id>)
```

For example: `feat(core): Set custom transaction source for event processors (#5722)`.

See [commit message format](https://develop.sentry.dev/commit-messages/#commit-message-format) for details.

The Github-ID can be left out until the PR is merged.

### Issues

Issues should at least be categorized by package, for example `package: Node`. Additional labels for categorization can
be added, and the Sentry SDK team may also add further labels as needed.

### Pull Requests (PRs)

PRs are merged via `Squash and merge`. This means that all commits on the branch will be squashed into a single commit,
and committed as such onto master.

- The PR name can generally follow the commit name (e.g.
`feat(core): Set custom transaction source for event processors`)
- Make sure to rebase the branch on `master` before squashing it
- Make sure to update the commit message of the squashed branch to follow the commit guidelines - including the PR
number

### Gitflow
See [Commit, Issue & PR guidelines](./docs/commit-issue-pr-guidelines.md).

We use [Gitflow](https://docs.github.com/en/get-started/quickstart/github-flow) as a branching model.
## PR Reviews

Please note that we cannot _enforce_ Squash Merge due to the usage of Gitflow (see below). Github remembers the last
used merge method, so you'll need to make sure to double check that you are using "Squash and Merge" correctly.

# PR reviews

Make sure to open PRs against `develop` branch.

For feedback in PRs, we use the [LOGAF scale](https://blog.danlew.net/2020/04/15/the-logaf-scale/) to specify how
important a comment is:

- `l`: low - nitpick. You may address this comment, but you don't have to.
- `m`: medium - normal comment. Worth addressing and fixing.
- `h`: high - Very important. We must not merge this PR without addressing this issue.

You only need one approval from a maintainer to be able to merge. For some PRs, asking specific or multiple people for
review might be adequate. You can either assign SDK team members directly (e.g. if you have some people in mind who are
well suited to review a PR), or you can assign `getsentry/team-web-sdk-frontend`, which will randomly pick 2 people from
the team to assign.

Our different types of reviews:

1. **LGTM without any comments.** You can merge immediately.
2. **LGTM with low and medium comments.** The reviewer trusts you to resolve these comments yourself, and you don't need
to wait for another approval.
3. **Only comments.** You must address all the comments and need another review until you merge.
4. **Request changes.** Only use if something critical is in the PR that absolutely must be addressed. We usually use
`h` comments for that. When someone requests changes, the same person must approve the changes to allow merging. Use
this sparingly.

You show generally avoid to use "Auto merge". The reason is that we have some CI workflows which do not block merging
(e.g. flaky test detection, some optional E2E tests). If these fail, and you enabled Auto Merge, the PR will be merged
if though some workflow(s) failed. To avoid this, wait for CI to pass to merge the PR manually, or only enable "Auto
Merge" if you know that no optional workflow may fail. Another reason is that, as stated above in 2., reviewers may
leave comments and directly approve the PR. In this case, as PR author you should review the comments and choose which
to implement and which may be ignored for now. "Auto Merge" leads to the PR feedback not being taken into account.

## Reviewing a PR from an external contributor

1. Make sure to review PRs from external contributors in a timely fashion. These users spent their valuable time to
improve our SDK, so we should not leave them hanging with a review!
2. Make sure to click "Approve and Run" on the CI for the PR, if it does not seem malicious.
3. Provide feedback and guidance if the PR is not ready to be merged.
4. Assign the PR to yourself if you start reviewing it. You are then responsible for guiding the PR either to
completion, or to close it if it does not align with the goals of the SDK team.
5. Make sure to update the PR name to align with our commit name structure (see above)
