== | == Roadmap == | ||
Given the large scope of the project, we are breaking the project down into quarterly milestones. Each milestone will aim to support a set of user scenarios. This roadmap is in the early stages and subject to significant change. It will be updated as milestones become clearer, with future milestones being less well defined than earlier ones. | |||
=== Milestone 0: December 2021 === | |||
Initial proof of concept. | |||
All testing will be performed with the NVDA screen reader, for two reasons: | |||
# Cache the World is all or nothing on Windows. That makes it easy to determine where we're at regarding real world usage. | |||
# The performance benefits are most necessary and noticeable on Windows. | |||
In milestone 0, the following capabilities will be provided: | |||
# Reading and navigating a page with text, links and headings. | |||
# Plain text editing: reading the line of text when focused; backspacing; moving the caret by line, word and character. | |||
# Access to formatting information: font, bold/italic, etc. | |||
# Access to screen coordinates on simple pages. | |||
# Loading very large pages will be at least 10x faster with the cache than without. | |||
==== Test Scenarios ==== | |||
# Do a Google search, navigate the results using heading navigation and follow a result link. | |||
# Fill out the form for a Google Advanced Search. | |||
# Go to https://www.reaper.fm. Check the formatting of the “This is REAPER.” text (which isn’t a heading even though it should be) and confirm that the font size is reported as bigger than the paragraph of text below it. | |||
# Build Gecko in the background. Do a Google search. Verify that the browser does not become unresponsive. | |||
# Load https://searchfox.org/mozilla-central/source/layout/base/nsCSSFrameConstructor.cpp. Page should take < 10 sec to be usable. | |||
# Open Gmail, find a message in the inbox, open it, read it, return to the inbox. | |||
# Compose a message in Gmail containing text, a link, a bulleted list and a block quote. Read back through the message. | |||
# Open Slack, use the quick switcher to switch to a channel, read some messages, write a message. | |||
==== Bugzilla ==== | |||
Note that the roadmap wasn't created until late in milestone 0, so many bugs are missing below. | |||

=== Milestone 1: March 2022 === | |||
Android. | |||
The primary focus of this milestone is getting the cache working for Android. Mozilla aims to implement Fission for Android in 2022h1. Modifying the existing multi-process architecture to support Fission on Android will require significant engineering effort. Rather than investing in a solution which we will be throwing away once the cache is implemented, we will instead switch Android to use the cache and extend the cache to include functionality required by Android. | |||
In milestone 1, the following capabilities will be provided: | |||
# The cache will support GroupPosition. | |||
# TextLeafRange will support word end and line end boundaries, which are needed for Android text navigation. | |||
# Pivot will support navigating text using TextLeafRange, which is needed for Android text navigation. | |||
# Cached screen bounds will be updated appropriately when scrolling. | |||
# Android will use the cache for all functionality except hit testing. | |||
# As an interim solution, Android will use the existing async IPDL mechanism for hit testing, updated to target the call at the correct document to handle OOP iframes. (Synchronous hit testing in the core cache will take longer to implement and will be done in a future milestone.) | |||
==== Test Scenarios ==== | |||
# TBD: simple website reading. News site? | |||
# TBD: filling a form. | |||
# TBD: character/word/line navigation. | |||
# With Talkback, load https://www.nvaccess.org/. Navigate to the embedded video in four different ways: item navigation, explore by touch, controls navigation and Talkback search. Activate the Play button to play the video. | |||
