Revision as of 09:01, 10 November 2017

Project Goals

  • Investigate the usage of current preferences:
    • Understand and document existing preferences (lifetime, type, whether they are still in use, etc.)
    • Clean up preferences (unused, incorrectly used, non-obvious).
  • Use preferences as performance tuning knobs and investigate the performance implications of these knobs.
    • Prioritize the preferences with their relevance to performance.
    • Tweak the preferences and run automated tests against the values to see their performance implications.

Participants

  • Kan-Ru Chen
  • Cervantes Yu
  • Will Wang
  • WeiCheng Pan
  • Shako Ho
  • Walter Chen
  • Askeing Yen

Roadmap

  • Find a systematic way to manage and prioritize default preference values.
    • Co-work with libpref redesign project on new persistence format of preferences.
    • Find performance related preferences during the process.
    • Get feedback from relevant teams.
      • Initially we may target JS related preferences.
    • Record the performance implications of preferences using the new persistence format.

Things to Consider

  • What's the new persistence format for preferences?
  • What data should a pref contain?
    • Internal name, a more descriptive name, description, default value, etc.
  • #include from smaller subsets in the final pref file.
    • Group prefs that are relevant (sharing the same prefix) in smaller files.
  • Standalone top branch indicates that the pref should be under some other branch.
    • There is only 1 pref beginning with "slider": slider.snapMultiplier
    • Move to browser.slider.snapMultiplier?
  • camelCase, underscore_names, or dashed-names?
  • Envisioning a front-end user interface that is more user-friendly than about:config?
    • Makes it easier for users to tweak or experiment with the browser.
  • Inline readonly prefs in code as constants?
