Summary:
We sometimes get large PRs that sit for a long time without being reviewed. In some cases, the PR touches too many files or lines, and the author would benefit from splitting the PR into smaller easier-to-review PRs. In this PR, we automatically flag such PRs using the existing Danger PR automation functionality.
This PR achieves the objective by doing the following:
* Add facebook-open-source-bot to `IssueCommands.txt`, allowing it to add labels and close issues/PRs via facebook-github-bot commands.
* Adds a `large-pr` command to facebook-github-bot. This command will add a short blurb, apply a new "Large PR" label, and close the PR.
* Updates the Dangerfile to check for PRs that touch over 600 lines and/or files. In such cases it will warn and then issue the large-pr command.
Additional changes:
* Tag core contributor PRs with the "Core Team" label. This is a slight change in policy, in that the label used to be applied after the fact (after the PR was escalated for review). It's more convenient to monitor labels, so we'll start checking for PRs tagged as such and ensure they get escalated as needed. cc skevy
Thanks to TheSavior for suggesting this change.
Testing against PR #10084 which touches over 600 lines:
```
$ cd danger
$ DANGER_GITHUB_API_TOKEN="e622517d9f1136ea8900""07c6373666312cdfaa69" npm run danger pr https://github.com/facebook/react-native/pull/10084
> @ danger /Users/hramos/git/react-native/danger
> node ./node_modules/.bin/danger "pr" "https://github.com/facebook/react-native/pull/10084"
{
fails: [],
warnings: [
{
message: "📋 Test Plan - <i>This PR appears to be missing a Test Plan.</i>"
},
{
message: "❗ Big PR - <i>This PR is extremely unlikely to get reviewed because it touches 613 lines.</i>"
}
],
messages: [],
markdowns: ["facebook-github-bot label Needs more information", "facebook-github-bot large-pr"]
}
```
Result: successfully flagged as being a large PR.

Summary:
The bot was incorrectly flagging PRs that do not touch IssueCommands.txt. This PR fixes the Dangerfile rule.
Verify the warning is generated on a PR that touches IssuesCommands.txt:
```
$ DANGER_GITHUB_API_TOKEN="e622517d9f1136ea8900""07c6373666312cdfaa69" npm run danger pr https://github.com/facebook/react-native/pull/15087

> node ./node_modules/.bin/danger "pr" "https://github.com/facebook/react-native/pull/15087"
{
fails: [],
warnings: [
{
message: "📋 Test Plan - <i>This PR appears to be missing a Test Plan.</i>"
},
{
message: "❗ Bots - <i>This PR appears to modify the list of people that may issue commands to the GitHub bot.</i>"
}
],
messages: [],
markdowns: []
}
```
Verify it does not warn on a PR that does not modify IssueCommands.txt:
```
$ DANGER_GITHUB_API_TOKEN="e622517d9f1136ea8900""07c6373666312cdfaa69" npm run danger pr https://github.com/facebook/react-native/pull/15089

Summary:
Testing Danger support in CI. Continuation of #14964, which Circle stopped building.
Update your node modules first: `npm install`
`npm run danger pr https://github.com/facebook/react-native/pull/14951`
Verify output. This PR should trigger a WIP warning, as well as a package.json warning:
```
> react-native@1000.0.0 danger /Users/hramos/git/react-native
> node ./node_modules/.bin/danger "pr" "https://github.com/facebook/react-native/pull/14951"
{
fails: [],
warnings: [
{
message: "👷 Work In Progress - <i>Do not merge yet.</i>"
},
{
message: "🔒 Changes were made to package.json - <i>This will require a manual import. Once approved, a Facebook employee should import the PR, then run `yarn add` for any new packages.</i>"
}
],
messages: [],
markdowns: ["This PR requires attention from the facebook/react-native team."]
}
```
`npm run danger pr https://github.com/facebook/react-native/pull/14946`
Verify output. This PR should trigger a warning against the lack of a test plan (note that the PR does have a test plan, but it does not title it as such):
```
{
fails: [],
warnings: [
{
message: "📋 Test Plan - <i>This PR appears to be missing a Test Plan</i>"
}
],
messages: [],
markdowns: []
}
```
`npm run danger pr https://github.com/facebook/react-native/pull/13186`
Should warn against a missing test plan:
```
{
fails: [],
warnings: [
{
message: "📋 Test Plan - <i>This PR appears to be missing a Test Plan.</i>"
}
],
messages: [],
markdowns: ["📄 Thanks for your contribution to the docs!"]
}
```
If the author is able to issue bot commands, we reasonably assume that this is coming from an established core contributor. Their PRs will be flagged for expedited review:
`npm run danger pr https://github.com/facebook/react-native/pull/14895`
```
{
fails: [],
warnings: [
{
message: "📋 Test Plan - <i>This PR appears to be missing a Test Plan.</i>"
}
],
messages: [],
markdowns: ["This PR has been submitted by a core contributor. Notifying facebook/react-native."]
}
```
