Finding Bugs to Fix Finding Bugs to Fix

If you want to fix bugs in the core parts of WordPress, but don’t know what to fix, here are some suggestions on finding one:

  • Try starting with tickets that have been tagged with the ‘good-first-bug’ keyword. They’re great for getting familiar with the process before attempting to solve more complicated problems.
  • Look through the ticket report for the latest release, in particular the Needs Patch group.
  • Look through the ticket report for “early” tickets. These tickets have been marked by contributing developers as needing attention early in the WordPress releaseRelease A release is the distribution of the final version of an application. A software release may be either public or private and generally constitutes the initial or new generation of a new or upgraded application. A release is preceded by the distribution of alpha and then beta versions of the software. cycle. Generally, this means a trusted core contributor has shown interest in it, “blessing” the ticket to a certain extent.
  • Look through the Awaiting Review report. These tickets have not yet been slated for the next release of WordPress, but if a developer takes an interest in it, that can change.
  • There are individual reports of tickets for a number of specialized areas: you may be interested in writing unit tests (see Automated Testing), working on or providing feedback for user interfaces and user experiences, tickets of interest to the mobile development team, and tickets requiring more documentation in the Codex.
  • If you are interested in tickets from a particular component, you can use the Query feature of Trac. For example, all open XML-RPC tickets, all open Multisite tickets grouped by milestones, and all open Accessibility tickets.
  • The WordPress development team has daily discussions on bug triagetriage The act of evaluating and sorting bug reports, in order to decide priority, severity, and other factors., and weekly project meetings. For dates and times, see the sidebarSidebar A sidebar in WordPress is referred to a widget-ready area used by WordPress themes to display information that is not a part of the main content.
