The UI and extension modules are among the most performance sucks in the SDK at the moment. They should be our first priority for removal after legacy add-on support is removed. This is the draft list of modules I intend to start with: ./addon/bootstrap.js ./addon/events.js ./addon/host.js ./addon/installer.js ./addon/manager.js ./addon/runner.js ./addon/window.js ./browser/events.js ./context-menu.js ./context-menu/context.js ./context-menu/core.js ./context-menu/readers.js ./context-menu@2.js ./dom/events-shimmed.js ./dom/events.js ./dom/events/keys.js ./frame/hidden-frame.js ./frame/utils.js ./hotkeys.js ./input/browser.js ./input/customizable-ui.js ./input/frame.js ./input/system.js ./keyboard/hotkeys.js ./keyboard/observer.js ./keyboard/utils.js ./model/core.js ./notifications.js ./page-mod.js ./page-mod/match-pattern.js ./page-worker.js ./panel.js ./panel/events.js ./panel/utils.js ./private-browsing.js ./private-browsing/utils.js ./self.js ./simple-prefs.js ./simple-storage.js ./system/child_process.js ./system/child_process/subprocess.js ./tab/events.js ./tabs.js ./tabs/common.js ./tabs/events.js ./tabs/helpers.js ./tabs/namespace.js ./tabs/observer.js ./tabs/tab-fennec.js ./tabs/tab-firefox.js ./tabs/tab.js ./tabs/tabs-firefox.js ./tabs/utils.js ./tabs/worker.js ./ui.js ./ui/button/action.js ./ui/button/contract.js ./ui/button/toggle.js ./ui/button/view.js ./ui/button/view/events.js ./ui/component.js ./ui/frame.js ./ui/frame/model.js ./ui/frame/view.js ./ui/id.js ./ui/sidebar.js ./ui/sidebar/actions.js ./ui/sidebar/contract.js ./ui/sidebar/namespace.js ./ui/sidebar/utils.js ./ui/sidebar/view.js ./ui/state.js ./ui/state/events.js ./ui/toolbar.js ./ui/toolbar/model.js ./ui/toolbar/view.js ./view/core.js ./webextension.js ./window/browser.js ./window/events.js ./window/helpers.js ./window/namespace.js ./windows.js ./windows/fennec.js ./windows/firefox.js ./windows/observer.js ./windows/tabs-fennec.js

Can we remove locale.js please? We have a fully functional moziLocaleService which should be used instead

It's definitely in for the offing, but it's not one of my highest priorities.

The plan is to migrate devtools off these modules, which won't happen until 57.

(In reply to Anthony Jones (:kentuckyfriedtakahe, :k17e) from comment #3) > The plan is to migrate devtools off these modules, which won't happen until > 57. Could you please give more details? What do you mean by "won't happen until 57"? Can we at least ensure that none of these modules are used by the devtools code that runs before the user has interacted with devtools in the session?

Hopefully devtools should migrate off these modules well before 57, but we can't remove them until we stop supporting SDK add-ons, which won't be until 57.

Do we need to somehow ensure that devtools actually migrates away? I'm worried about the "hopefully" part in comment 5. :-)

Well, I say "hopefully" because I have no control over or real involvement in what the devtools team does, so it's the best I can say. Perhaps someone from that team can say something more definite.

I have moved over to the Stylo effort, so I'm no longer working full time on DevTools. :pbro, can DevTools assign an owner for this effort to drive it to completion?

Can we clarify that if we have zero SDK add-ons on 57 release, this ceases to be a concern for quantum flow?

Perhaps someone > from that team can say something more definite. Yeah sorry my comment wasn't directed at you, my apologies if this came off the wrong way. I just want to ensure the work is prioritized correctly and the devtools team is aware of it. :-) Let's wait to hear from Patrick...

Bug 1350645 should now be up to date with respect to blockers. I've filed all the remaining blocker bugs based on this comment from Kris: bug 1350645 comment 2. A bunch of bugs have already been fixed, and 7 remain. As of today, we do not have anyone in DevTools assigned to work on this full time. So this is being worked on rather slowly, as a side thing to people's quarterly goals, but we do have it on our radar and are making progress. My plan so far is: I'll make sure there's at least some momentum on this until the end of Q2 (i.e. a few more bugs get fixed). And then assign someone to work on this full time at the beginning of Q3 (which means before the 57 nightly cycle starts). Looking at the remaining list of blockers in bug 1350645, I think this should work. Only bug 952653 seems big, the rest looks simple. Again, this is based on the high priority list given by Kris in bug 1350645 comment 2. If this list changes or if we need something sooner than this, let me know, we can always change priorities (of course, at the cost of something else no being done in Q2).

And then assign > someone to work on this full time at the beginning of Q3 (which means before > the 57 nightly cycle starts). Was that able to happen? I see lots of bugs being added/removed from the tracker :)

(In reply to Andrew Overholt [:overholt] from comment #12) > Was that able to happen? I see lots of bugs being added/removed from the > tracker :) Yes. We have kicked off a project in Q3 aiming at removing all of our SDK dependencies in DevTools. 2 of the big ones we have are Heritage and Event, which we are working on first. The team has been creating many bugs to track the work. All of which should be in the dependency tree of bug 1350645.

From /devtools, it looks like we are "only" depending on these modules: - clipboard - core/heritage - event/core - event/target - indexed-db - lang/functional/concurrent.js - system/child_process/subprocess - system/environment - system/events - system/runtime - timers - util/object - util/uuid In this list, only subprocess is referenced in comment 0. This is tracked by bug 1378832, should we only/mostly focus on that? Or is the bug about removing all the SDK? Then we should rename it. What is the target here? Should we aim for: * in two weeks as 57 cycle begins? * before 57 goes to beta? * in mid-cycle of 57? Is DevTools the only blocker here? If yes, once we are on 57, should be remove SDK modules one by one as we start removing dependencies on them?

We have a bug to remove all dependencies from SDK from devtools (bug 1350645), but *when* are you planning to remove the SDK from the code base exactly? This will help us prioritise. I've been reading these comments and the comments elsewhere (omg there are so many bugs opened for this) and none points exactly to a fixed date. Is it "after 57 is released" meaning sometime in the 58 cycle or...? etc thanks!

I'm planning to disable most of the SDK tests as soon as 56 merges to beta. I'm hoping to stop shipping most SDK modules by the end of the 57 cycle

Just for clarification, when discussed, we had agreed no SDK removal until at least 58/59. Support for loading SDK addons goes away in 57, but removal shouldn't be targeted before 58. Correct?

(In reply to Kev Needham [:kev] from comment #62) > Just for clarification, when discussed, we had agreed no SDK removal until > at least 58/59. Support for loading SDK addons goes away in 57, but removal > shouldn't be targeted before 58. Correct? The plan has been to remove most of the SDK in 57 for the last couple of months. We initially planned to push it back for the sake of Android, but since then we've come to the agreement that Android WebExtension support is good enough that that's not necessary.

kk. we should remind test/release as well, jic there are any lingering SDK extensions that need migrating. thankees.
