Topics

• Let’s review this patch!
• Still hacking on WindowsJumpLists!
  • Goal: I want the JumpListManager to only ever be accessed off of the main thread, so that the main thread in the parent process never has to await a lock.
    • Get rid of maxListItems, since it doesn’t appear to be used
    • Get rid of isListCommitted
    • Make .available return a Promise
    • Make abortListBuild return a Promise
    • Make deleteActiveList return a Promise
    • Make SetAppUserModelId return a Promise
    • Add WebIDL for JumpListShortcutDescription and add populateJumpList method to JumpListBuilder.
    • Custom List (this is the Frequently Visited stuff) - Frequent is ENABLED by default - Recent is DISABLED by default - Don’t need separators
    • Tasks
    • Update methods so that tasks and custom lists are added in the same method call. So a single populate method that takes something like… (taskDescriptions, customTitle, customListDescriptions)
    • Finish the URL removal thing. Basically, if an item was removed via the shell, the next call to AppendCategory cannot include that item with the same display name - the next call needs to display something else entirely.
    • See how Thunderbird uses JumpListBuilder in case there are things we need to support there.
    • Figure out how to make the above testable. Then write tests.
      • Let’s update WinTaskbar to have a new method that can be accessed from native code (so not through XPCOM), called, like, DoCreateJumpListBuilder or something. Have it take an argument that is a reference to something that implements a JumpListManager interface. Have JumpListBuilder move that thing to the background thread - the background thread owns it. Then, in our tests, have our GTest call DoCreateJumpListBuilder, passing it something that mocks out JumpListManager. And then call it’s populateJumpList method for testing.
    • Make our approach preffable. Put all the old stuff back (gulp), and update WindowsJumpList to use the new mechanism on a pref.
    • Implement clearJumpList (it’s called deleteActiveList)
    • See if the above works. If it does, get rid of old changes that we don’t need and merge patches down
    • Update WindowsJumpList.jsm to use the new API instead of the old one.
    • Remove the old implementation! Hooray!
    • Migrate off of dedicated lazy thread to background thread pool
