This document describes how the Angular team uses labels and milestones to triage issues on github.

Every triaged issue must have four attributes assigned to it:

* `priority` -- P0 through P4. P0 issues are "drop everything and do this now". P4 are nice to have.

* `component` -- Which area of Angular knowledge this relates to.

* `effort` -- Rough assessment of how much work this issue is. E.g. `effort: hour` means

"probably a few hours of work".

* `type` -- Whether this issue is a bug, feature, or other kind of task.

Untriaged issues are any issues in the queue that don't yet have these four attributes.

You can view a report of untriaged issues here, in our

[Angular Triage Dashboard](http://mhevery.github.io/github_issues/).

Issues should also have a clear action to complete that can be addressed or resolved within the

scope of Angular 2. We'll close issues that don't meet these criteria.

Any issue that is being worked on must have:

* An `assignee`: The person doing the work.

* A `Milestone`: When we expect to complete this work.

We aim to only have at most three milestones open at a time:

* Closing Milestone: A milestone with a very small number of issues, about to release.

* Current Milestone: Work that we plan to complete within one week.

* Next Milestone: Work that is > 1 week but current for the team.

The [backlog](https://github.com/angular/angular/issues?q=is%3Aopen+is%3Aissue+no%3Amilestone)

consists of all issues that have been triaged but do not have an assignee or milestone.

Because of the cumulative pain associated with rebasing PRs, we triage PRs daily, and

closing or reviewing PRs is a top priority ahead of other ongoing work.

Every triaged PR must have a `pr_action` label assigned to it and an assignee:

* `pr_action: cleanup` -- more work is needed from the current assignee.

* `pr_action: discuss` -- discussion is needed, to be led by the current assignee.

* `pr_action: merge` -- OK to merge this as soon as tests are green, `pr_state: LGTM`, and `CLA:

yes` are true. assignee (or anyone else) can merge.

* `pr_action: review` -- work is complete and comment is needed from the assignee.

In addition, PRs can have the following states:

* `pr_state: LGTM` -- PR may have outstanding changes but does not require further review.

* `pr_state: WIP` -- PR is experimental or rapidly changing. Not ready for review or triage.

* `pr_state: blocked` -- PR is blocked on an issue or other PR. Not ready for review or triage.

Note that an LGTM state does not mean a PR is ready to merge: for example, a reviewer might set the

LGTM state but request a minor tweak that doesn't need further review, e.g., a rebase or small

uncontroversial change.

PRs do not need to be assigned to milestones, unless a milestone release should be held for that

PR to land.

Victor (`vsavkin`) and Tobias (`tbosch`) are owners of the PR queue. Here is a list of [current

untriaged PRs](https://github.com/angular/angular/pulls?utf8=%E2%9C%93&q=is%3Aopen+no%3Amilestone+is%3Apr+-label%3A%22pr_action%3A+cleanup%22+-label%3A%22pr_action%3A+merge%22+-label%3A%22pr_action%3A+review%22+-label%3A%22pr_action%3A+discuss%22+-label%3A%22pr_state%3A+blocked%22+-label%3A%22pr_state%3A+WIP%22+).

What should you be working on?

1. Any PRs that are assigned to you that don't have `pr_state: WIP` or `pr_state: blocked`

1. Any issues that are assigned to you in the lowest-numbered Milestone

1. Any issues that are assigned to you in any Milestone

If there are no issues assigned to you in any Milestone, pick an issue, self-assign it, and add

it to the most appropriate Milestone based on effort.

Here are some suggestions for what to work on next:

* Filter for issues in a component that you are knowledgeable about, and pick something that has a

high priority.

* Filter for any small effort task that has the special `cust: GT` or `cust:Ionic` tags,

and priority > P3.

* Add a new task that's really important, add `component`, `priority`, `effort`, `type` and

assign it to yourself and the most appropriate milestone.

How urgent is this issue? We use priority to determine what should be worked on in each new

milestone.

* `P0: critical` -- drop everything to work on this

* `P1: urgent` -- resolve quickly in the current milestone. people are blocked

* `P2: required` -- needed for development but not urgent yet. workaround exists, or e.g. new API

* `P3: important` -- must complete before Angular 2 is ready for release

* `P4: nice to have` -- a good idea, but maybe not until after release

Rough, non-binding estimate of how much work this issue represents. Please change this assessment

for anything you're working on to better reflect reality.

* `effort: hour` -- straightforward issue that can be resolved in a few hours, e.g. < 1 day of work.

* `effort: day` -- issue that will be a few days of work. Can be completed within a single

milestone.

* `effort: week` -- issue that will likely take more than 1 milestone to complete.

What kind of problem is this?

* `type RFC / discussion / question`

* `type bug`

* `type chore`

* `type feature`

* `type performance`

* `type refactor`

More active discussion is needed before the issue can be worked on. Typically used for `type:

feature` or `type: RFC/discussion/question`

Managed by googlebot. Indicates whether a PR has a CLA on file for its author(s). Only issues with

`cla:yes` should be merged into master.

This is an issue causing user pain for early adopter customers `cust: GT` or `cust: Ionic`.

Only used on closed issues, to indicate to the reporter why we closed it.
