== Review flags ==
The JS team uses the review flags the same way as the rest of Gecko developer. The only difference is the lack of "r-" when a review needs to be revisited, instead the review request is canceled with comments. The "r-" flag is used only in a few cases where multiple reviewers are requested on the same patch, and one of them is opposed to the changes.

== Priority Flags ==


Priority flags are set based on the current goals.  The list of goals can be found in the JS Team document which list all the goals.
[https://firefox-source-docs.mozilla.org/bug-mgmt/guides/priority.html Priority flags] are used to track whether a bug is going to be worked on soon.
The addon [https://addons.mozilla.org/en-US/firefox/addon/bugzilla-triage-helper/ bugzilla triage helper] can be used to set the P1, P2, P3 and P5 (no P4) flags
 
* P1: P1 goals or blockers, Security issues. (to be fixed ASAP)
* P2: P2 goals or blockers. (scheduled to be fixed in an upcoming version)
* P3: P3 goals or blockers. (backlog; to be fixed one day)
* P5: (not a priority for Firefox product; might never be fixed)


The [https://firefox-bug-handling.mozilla.org/triage-bugzilla Firefox Bug Handling page] describes the logic to follow to set the priority flag and status flags.
* P1: The bug is being worked on, or it should urgently be worked on.
* P2: This is in someone todo-list.
* P3: backlog; to be fixed … one day.
* P4: There is no P4.
* P5: Patches are welcome!

=== P1 re-triage ===


A weekly meeting is held every Thursday to re-triage P1 which have seen no activity for a while. The following searches are lists of non-meta and non-stalled P1 issues affecting Firefox VV.

This page explains how the JavaScript Team uses Bugzilla.

Bugzilla components

Whiteboard flags

A few whiteboard flags are used today in the JS components:

As a convention, anybody can follow the following naming for using the whiteboard to improve Bugzilla searches. However, note that whiteboard searches are not indexed in Bugzilla databases and this might lead to performance issues.

  • [:nick:...] Used by the user :nick for managing bugs.
  • [#channel:...] Used by members of the IRC #channel for managing bugs.

Priority Flags

Priority flags are used to track whether a bug is going to be worked on soon.

  • P1: The bug is being worked on, or it should urgently be worked on.
  • P2: This is in someone todo-list.
  • P3: backlog; to be fixed … one day.
  • P4: There is no P4.
  • P5: Patches are welcome!

Severity

Severity flags should be N/A for enhancement and tasks. Any others should have a severity set from S1 to S4, which definitions are listed in the source documentation.

Triage

A meeting is held every week, on Tuesday 9am PT. (contact Steven De Tar, to be invited)

The triage effort is currently held by Steven De Tar, Nicolas B. Pierron, Bryan Thrall, and Matthew Gaudet. They mainly work off the following lists:

  • List of non-prioritized bugs - This list is used to set the missing priority flags and whiteboard flags to the corresponding bugs and sometimes needinfo? people.
  • BugDash - Scroll down to the bottom, under "Pending Untriaged (defects only)". This reports per-component the number of bugs which need to be triaged.
  • Triage Center — List all non-triaged bugs for all JS components.
