Work with the Jetpack team to implement a core set of modules. This is currently looking like JEPs 102 - 116, over releases 0.3, 0.4 and 0.5.

Status

IN FLIGHT JEPs are owned, and in development.


Team:

  • Lead: Dietrich
  • Members: Drew, Paul, Felipe, Marco

Modules owned by Fx-team members

JEP Module Owner Target Status Notes
102 Single UI (Addon Bar) Marco/Dietrich 0.4 on track Had a meeting with all the UX and Jetpack people about this. Boriss estimating full design delivery by 5/1. Going to implement infrastructure first, estimating two weeks for basic "Phase 1" implementation, as of 4/16.
104 Simple storage Drew 0.5 blocked Blocked by bug 553020 (which is at-risk for 0.3). Estimates 4 weeks of work for implementation.
105 Lifecycle Dietrich 0.4 planning stage bug 549324. Blocked by bug 553020 (which is at-risk for 0.3), and on the EM's support for reboot-less extension installs (bug 555349. Estimate 2 weeks for implementation.
108 Page Worker Felipe 0.4 on track Felipe has a first-cut patch up.
109 Request Zpao 0.4 planning stage Some implementation already done. Paul estimates 2 weeks for implementation.
112 Context menu Drew 0.3 on-track bug 548590, has patch, in reviews.
114 Places Marco 0.4 in-progress Core work done by ddahl, but needs API review for Jetpack API consistency. Marco is out on vacation, but said some API and code work still needs to happen, but nothing major. Still targeting 0.4 for now.
116 private browsing Zpao 0.4 not started Paul talked with Myk about the spec, estimates 2 weeks for implementation.

Other modules, assist if necessary

JEP Module Owner Target Status Notes
103 Panels Myk 0.3 at risk ping enn to see if need anything
106 Registered urls Brian 0.4 on track
107 Page mods Nicolay tbd on track Myk's working w/ him
110 Tabs Atul 0.3 on track might need owner for post-0.3 development
111 Selection Eric Jung 0.3 on track
113 Localization Gandalf 0.3 on track for client, need webdev for server, likely later release
115 Content frames completed spec, no impl

Goals

  • Help Labs implement modules for JEPs 102 - 116.
  • Bonus goal: Drive code reviews core Jetpack code (bug 551311)

Background

Jetpack's architecture under versions 0.8 and earlier (now called the Jetpack Prototype) is being phased out for a new architecture called the Jetpack SDK. Check the SDK docs and wiki for details, but briefly, the differences between the two:

  • The Jetpack SDK is a framework for making (traditional) extensions.
  • "Jetpacks" produced under the SDK are actually XPIs. They're real extensions. Under the Prototype they were single JS files.
  • Since jetpacks are now extensions, it no longer makes sense to say "I made a jetpack." It's more like, "I made an extension using Jetpack."
  • Jetpack itself is no longer an extension. It no longer makes sense to say, "I installed Jetpack."
  • The SDK is basically a toolchain, runtime, and API -- a framework.
  • The SDK is very loosely integrated with Firefox. The runtime is bundled in each XPI. Aside from changes required to support the SDK's high-level APIs, the runtime doesn't require any significant changes to Firefox or Gecko. A (re)loadable extension mechanism is being worked on, but it's like icing on the cake.
  • The SDK has a security model, the Prototype didn't.
  • Roughly speaking, there are two layers of APIs under the SDK. There's a low-level, chrome-privileged layer that wraps the platform. And there's a high-level, secure, low surface area, and friendly layer that builds on the lower. It's the higher layer that might be thought of as "the Jetpack API," but it's entirely possible to use the lower to build an extension.
  • The Bespin IDE of the Prototype will be replaced with a contracted-out in-browser IDE called "FlightDeck." (Maybe you've heard of it?) FlightDeck provides a nice UI to the SDK's toolchain. It will be available as a Web app.
