Getting reviews

Thorough code reviews are one of Mozilla’s ways of ensuring code quality. Every patch must be reviewed by the module owner of the code, or one of their designated peers.

To request a review, you will need to specify a review group (starts with #). If there is not, you should select one or more usernames either when you submit the patch, or afterward in the UI. If you have a mentor, the mentor can usually either also review or find a suitable reviewer on your behalf.

For example, the syntax to request review from a group should be:

Bug xxxx - explain what you are doing and why r?#group-name

or

Bug xxxx - explain what you are doing and why r?developer-nickname

Getting attention: If a reviewer doesn’t respond within a week, or so of the review request:

  • Contact the reviewer directly (either via e-mail or on Matrix).

  • Join developers on Mozilla’s Matrix server, and ask if anyone knows why a review may be delayed. Please link to the bug too.

  • If the review is still not addressed, mail the reviewer directly, asking if/when they’ll have time to review the patch, or might otherwise be able to review it.
