From looking at the code of these methods, it seems a lot of what is done there will only be needed if the user is going to open the menu panel; could we delay initialization of these UI components until the user hovers the hamburger button?
Yeah, there probably is alot we can do here, and is probably right up eoger's alley :) One clarification, by "jank" do you mean actual jank in terms of events not being processed, or is the concern simply the time it takes? For example, I notice that much of browser-syncui's time if after a couple of promises are resolved, so it's not clear that actually is janky or that the UI is blocked during this time.

The former, as shown in the profile I linked where there's a 588ms event processing delay (this profile was taken on a slow laptop with an i3 CPU). > For example, I notice that much of browser-syncui's time if after a > couple of promises are resolved, so it's not clear that actually is janky or > that the UI is blocked during this time. My guess is that these promises are resolved immediately when it's not the first browser window. This is a profile of jank when opening a new window, not of opening the first window on startup.
Attachment #8855945 - Flags: feedback?(markh)
This is VERY wip. We move the observers and the "cached" state in a module shared between all windows and fetch this state on mouseover on the PanelUI button. I know that Mark probably would want this patch to be more ambitious, which will probably happen in the next iterations, but we have to start somewhere :)

Gijs, you might be able to offer some advice here. We are trying to update the hamburger panel's sync state as late as possible (ie, just before the panel is shown). This patch adds: > document.getElementById("PanelUI-button").addEventListener("mouseover", () => { > this.updateUI(); but I'm not sure that's ideal, especially with a11y in mind. What do you suggest?

This is hopefully limited to what we need to show the "needs reauth" badge. * Almost everything else, done as the panel is shown the first time. Eg, most observers and these customize events would also fall into that second category. IOW, I think we should try and defer far more than just the updateUI if we can.

We need to be guided by the profiler. Obviously that's not true though if the module is lazy :) To be clear, I'm not against the module. I'm also not opposed to unifying browser-fxaccounts and browser-syncui (which may or may not make a module less attractive.
(In reply to :Gijs from comment #9) > Can we use the popupshowing event instead? I suspect that whatever route we take, there's a possibility that due to async things we might end up updating the UI after it has actually shown. If that's true, it might make sense to find/invent something like gBrowserInit.delayedStartupFinished, but for a window, and have that force initialization - ie, accept a slightly-less-than-ideal experience in the edge-case of hamburger shown immediately on opening in exchange for faster window creation time.

I haven't looked into this bug (or the patches) in detail. But there's a few things here that seem potentially relevant. In no particular order: - use a push rather than pull model for the state. This means state should be synchronously available, pushed from whatever handlers we need to have for the sync stuff, rather than asynchronously fetching sync state and thus risking races and other stuff. Then we can easily ensure we update the state of the panel only onpopupshowing, avoiding extra work on window startup. - avoid triggering reflows from the sync code that changes state in the panel. Ideally by avoiding markup and/or hidden/visible changes for nodes (or ensuring their parents sizes remain the same, in a way that can be determined by the layout code such that it doesn't need to reflow everything else. - extra JSMs are more problematic in the content than the parent process, though if we can avoid fetching sync state immediately when the initial window opens that would be ideal - I'm confused by the delayedStartupFinished thing. We already have this, I think? What's wrong with delayed startup finished?
> I'm confused by the delayedStartupFinished thing. We already have this, I > think? What's wrong with delayed startup finished? delayedStartupFinished is per-process, right? I'm thinking something for per-window state - eg, I could imagine that listening for popupshowing could be the *only* thing we do on window creation, with other init happening soon after (or by the event handler if necessary)

It feels like we're talking about different things. https://dxr.mozilla.org/mozilla-central/rev/f914d40a48009c5acd1093e9939cc0ec035696dd/browser/base/content/browser.js#1249 - gBrowserInit._delayedStartup, and its resulting finished bool, is per-*parent-window*. Not per-process. Do we have a different delayedStartupFinished?

> Can we use the popupshowing event instead? Yes The work I just posted I still WIP. No need to review for now, consider this a work-backup. I still intend to merge browser-fxa and browser-syncui. Notable changes include: - State is fetched synchronously, which removes a bunch of edge cases and makes everything easier to understand. This is a trade-off of course, because the first time we fetch the state we basically block on I/O. Maybe not a great idea, since the first time we fetch the state is in browser-fxa init(). - Remove the un-used customization mode code.

Block synchronously (main thread) or asynchronously (panel won't show until we have the data) ? We shouldn't add main-thread IO in an effort to fix this perf bug.
Flags: needinfo?(eoger)
Yes, I discussed this with Mark yesterday, this will go away in favor of browser-fxa calling a UIState method that roughly translates to "please tell me if I need to show the badge". UIState eventually sends back an observer notification at some point in the future. We assume by default that we don't need to show a badge since most users will not encounter the problem.
Flags: needinfo?(eoger)
Here's a new shot at this. Notable changes: * The most important logic part is in setTimeout() in gSync#init. Basically we wait 1 sec before requesting the UI state. - If we are the first window, ensureReady will be false and we will get an ON_UPDATE message shortly after UIState initializes (side effect of ensureReady). - For the subsequent windows, we only update the UI if we are in a "sync configured" state, otherwise we do not need to update the UI at all, because it's already in the right state (hence the part 3 of this patch). * browser-fxa and browser-syncui merged into browser-sync. Yay! * We listen to WAY WAY less observer notifications now (see UIState). If we have regressions, we can always add them back later, this is OK. We DEFINITELY want extensive QA testing if this patch sticks, because we could break many things. * The UIState now tracks the last sync date and the current syncing status. * I kept the broadcasters, we can revisit that later if we want to. This is not critical.

Basically we > wait 1 sec before requesting the UI state. Could this use https://developer.mozilla.org/en-US/docs/Web/API/Window/requestIdleCallback instead of the timeout? I've recently seen a profile (on a slow netbook) where a 10s timeout wasn't enough for the download manager's delayed initialization to run after we were fully done with startup.
That sounds like a great idea, we will also need to confirm using the profiler that we are getting the behavior that we want using this.

I think this is ready for a formal review now. The previous comments have been addressed and I added tests for both browser-sync and UIState.
Notes from talking with Markh today: - Remove the panelUI event listener - Make FxAccountsWebChannelHelper lazy in FxAccountsWebChannel, and stop pulling FxAccountCommon.

We should probably also reset it to null if we aren't signed in

In manual testing I noticed a bug - sign in to sync, then immediately open the hamburger menu - it remains in the "not signed in" state until the sync *completes*. I don't understand why as you do listed for onlogin, but also didn't try and debug :)
I'm still unable to reproduce the bug you cited mark, I even tried with a full build on Windows. Could you provide some debug info maybe?

I see a performance improvement with this patch: == Change summary for alert #6368 (as of May 03 2017 23:16 UTC) == Improvements: 3% tpaint windows7-32 opt 296.09 -> 288.23 For up to date results, see: https://treeherder.mozilla.org/perf.html#/alerts?id=6368
Yay! Kanchan, this patch changed a lot how/when we re-draw the Sync UI. This includes the Sync/FxA status bar in the hamburger menu, the synced tabs panel in the hamburger menu and the Tools->Sync Now/"Sign-in to Sync" menu item in the menu bar. We want to make sure this patch didn't break anything, especially when the user account state changes (unconnected/unverified/password changed somewhere else-needs re-connection/connected). Could you give it a round of QA once it's in Nightly? Thanks!

Thanks! I encounter an intermittent bug 1362190 during smog testing of this bug fix. Sync/FxA status bar, Tools->Sync Now/"Sign-in to Sync" menu item in the menu bar looks/works good. Other than bug 1362190, I didn't encounter any issue with various user account state changes (unconnected/unverified/re-connection/connected/password changed) or with any other FxA setting as of yet. I will do thorough testing on this next week. Thanks!
