The code added in bug 1347204 ends up eagerly loading LightweightThemeChildListener.jsm in every content process, even though it makes some pretense of doing it lazily. This leads to a 17K memory regression for every base content process. At this point, you should probably just wait for bug 1471025 to land, and use the sharedData map for the lightweight theme data, so AS can just fetch it when it's needed. But this definitely needs to be fixed.
Whiteboard: [overhead:17K]
I don't know if we can use the shared memory map from bug 1471025, simply because there's per-window theming to handle. However, I can definitively give a try to load LWTChildListener.jsm more lazily than now.

Theme data can't be shared between windows/processes if it's different based on the window.

Sure it can. It just needs to be keyed by window.
So, jotting down a few ideas here: 1. We should ensure that the LightweightThemeChildListener is only ever loaded in the privileged content process, once we turn that process on by default. That'd rely on bug 1472212 landing and sticking, but is probably a good idea in general - I highly doubt we'd ever want to expose this API to any pages outside of the privileged content process. 2. We could try to use the SharedData structure to make sure the content processes (or privileged content process, once it's turned on) are aware of all of the individual styles set per window, keyed on some kind of window identifier. I'm not sure if each TabChild currently has an easy way of determining which window they're in, but if not, we'd probably need to add it and expose it. The parent would be responsible for updating this structure any time the theme decides to change for one or more windows. 3. Keep the current general design, but make the LightweightThemeChildListener even lazier by only ever loading it if one of the about: pages it cares about is loaded (so, only load it in the event that the LightweightTheme:Support event is fired). If and when the message with the theme data comes down from the parent, have the stub hold onto it until that event appears.
I'd really rather it only ever be loaded when an about: page that requires it is open. Using sharedData is the easiest way to make that work. It allows us to synchronously fetch the theme data when we need it, and directly add a "change" listener if we need to care about dynamic updates. It should also make the code trivial enough that it can go into some other privileged script that we load for those pages, rather than requiring its own JSM.

Ideally, we'd implement it natively, and update it whenever we attach a FrameLoader to a browser.

Sorry, but this is absolutely not P3. We can't afford a 17K content memory regression at this point. I've spent hours working to get a single 10K improvement in some areas. A 17K regression that isn't fixed is going to need to be backed out.

What about tab detaching ?

We already update the TabContext on frameloader swap, which is why I suggested it.
Alright, let's see if we can get the SharedData approach to work. Here's a strawman breakdown: 1. See if we can send down a window identifier to each frameloader on construction, and ensure that the identifier is updated on frameloader swaps 2. Have the parent populate the SharedData storage with the dynamic themes as they update, keyed on the window identifiers 3. Have tab-content.js not load LightweightThemeChildListener until one of the about: pages that it cares about loads 4. When LightweightThemeChildListener is loaded, have it read from SharedData, and get the right theme values for the window that the tab belongs to. Send that information back to the page that's loading contentTheme.js 5. During frameloader swaps, have the LightweightThemeChildListener notice if the associated tab's window ID has changed, and if so, update the contentTheme.js script appropriately. Hey kmag, reading bug 1471025 (mainly the tests), does this mean we'd be using prefs as the backing store for the theme information?

Gotcha, gotcha - okay, yeah, we can totally use this. Thanks!
Priority: -- → P1
Once bug 1474662 merges, the outer window ID of the browser window will be available to frame scripts. I think what we'll probably want to do then is to have something in the parent process monitor for lightweight-theme-styling-update notifications, and then set the content-relevant properties in the SharedData structure. In tab-content.js, we should have something that only loads LightweightThemeChildListener.jsm if one of the about: pages in the whitelist is loaded. LightweightThemeChildListener.jsm should then wait for the content events for the theme requests, and send the information from the SharedData structure. It should also add a change event listener to the SharedData structure, and send LightweightTheme:Update events down to the about: page if the SharedData for the theme data changes. LightweightThemeChildListener should use the chromeOuterWindowID information exposed in bug 1474662 to choose the right theme properties. I think we should also modify contentTheme.js to request theme information from the LightweightThemeChildListener on the pageshow event. That way after frameloader swaps, it'll get the update without the parent having to tell it with an extra message (this means I believe we can back out bug 1473270). Hey ntim, do you think you'd have the time to take on this refactor in the 63 cycle?

It doesn't serve any purpose before then, and adds non-trivial memory overhead..
Reviewing today - just freeing up from meetings.
Comment on attachment 8992325 [details] Bug 1474163 - Make use of sharedData for content theme data. https://reviewboard.mozilla.org/r/257196/#review264784 Hey ntim, this is a solid approach - I have some minor suggestions, but this looks like it's on the right track. See below! Thanks! ::: browser/base/content/tab-content.js:91 (Diff revision 6) > - addMessageListener("LightweightTheme:Update", this); > - sendAsyncMessage("LightweightTheme:Request"); > - this.init = null; > + "about:newtab", > + "about:welcome", > +]); > - }, > > - handleEvent(event) { > +let lastThemablePage; Hm. This looks like a good way of leaking DOM windows... this doesn't ever get cleared, it seems. ::: browser/base/content/tab-content.js:93 (Diff revision 6) > > - handleEvent(event) { > +let lastThemablePage; > - return this.childListener.handleEvent(event); > - }, > > - receiveMessage(msg) { > +addEventListener("LightweightTheme:Support", function({ originalTarget }) { So at first glance, this is good - the event will be coming in on the pages that have contentTheme.js, and then we check the content documentURI against the whitelist. So I think this is a sufficient way of knowing when to finally load the JSM. However, I notice that the pageshow event handler is essentially doing the same thing. Also, the pageshow event handler should fire in the original not long after loading contentTheme.js... so perhaps we can just have a pageshow event handler here instead that checks against the whitelist, and get rid of the LightweightTheme:Support event? ::: browser/base/content/tab-content.js:106 (Diff revision 6) > +Services.cpmm.sharedData.addEventListener("change", function({ changedKeys }) { > + if (changedKeys.includes(`theme/${chromeOuterWindowID}`) && > + lastThemablePage == content && themeablePagesWhitelist.has(content.document.documentURI)) { > + LightweightThemeChildHelper._update(chromeOuterWindowID, content); > + } > +}); This is another thing that probably only needs to happen inside of the JSM. Either have the JSM (again) export a class that can be instantiated per global / chromeOuterWindowID, and have it monitor for the appropriate change event.

Either have the JSM (again) export a class that can be instantiated per global / chromeOuterWindowID, and have it monitor for the appropriate change event. If the memory overhead of instantiating an instance of that class per top-level content is prohibitive, another idea would be to have the JSM monitor for changes on the theme/ namespace, and then iterate all top-level DOM windows, searching for ones pointed at pages in the whitelist, and then updating them. You can iterate windows like this: https://searchfox.org/mozilla-central/rev/c296d5b2391c8b37374b118180b64cca66c0aa16/devtools/server/actors/targets/content-process.js#41-48

Comment on attachment 8992325 [details] Bug 1474163 - Make use of sharedData for content theme data. https://reviewboard.mozilla.org/r/257196/#review265394 Hey ntim, I think this is looking pretty good - but needs a tiny bit of cleanup (there's some debugging stuff in there, and I have some naming / organizing suggestions). Thanks! ::: browser/base/content/tab-content.js:85 (Diff revision 7) > - receiveMessage(msg) { > - return this.childListener.receiveMessage(msg); > - }, > -}; > - > +let themeablePagesWhitelist = new Set([ > + "about:home", > + "about:newtab", > + "about:welcome", > +]); What about storing this as a property on E10SUtils? That way, you don't have to pass it into LightweightThemeChildHelper. ::: browser/base/content/tab-content.js:93 (Diff revision 7) > - > +]); > -LightweightThemeChildListenerStub.init(); > > +addEventListener("pageshow", function({ originalTarget }) { > + if (originalTarget.defaultView == content && themeablePagesWhitelist.has(content.document.documentURI)) { > + console.log(content.document.documentURI) Please remove this logging. ::: browser/modules/LightweightThemeChildHelper.jsm:20 (Diff revision 7) > - if (name == "LightweightTheme:Update") { > - this._lastData = data; > - this._update(data, target.content); > - } > + listener: null, > + whitelist: [], > + _listen(whitelist) { > + if (!this.listener) { > + this.whitelist = whitelist; > + console.log("WHITELIST", whitelist) Please remove this, and the rest of the console.log logging. ::: browser/modules/LightweightThemeChildHelper.jsm:33 (Diff revision 7) > + while (windowEnumerator.hasMoreElements()) { > + const window = windowEnumerator.getNext().QueryInterface(Ci.nsIDOMWindow); > + const tabChildGlobal = window.QueryInterface(Ci.nsIInterfaceRequestor) > + .getInterface(Ci.nsIDocShell) > + .sameTypeRootTreeItem > + .QueryInterface(Ci.nsIInterfaceRequestor) > + .getInterface(Ci.nsIContentFrameMessageManager); > + const {chromeOuterWindowID, content} = tabChildGlobal; > + if (changedKeys.includes(`theme/${chromeOuterWindowID}`) && > + content && this.whitelist.has(content.document.documentURI)) { > + this._update(chromeOuterWindowID, content); > - } > + } Going back to a previous conversation we had - I guess there is some risk here that this could impact performance immediately after window opens (since we'll add a new entry on window opening, and then iterate all tabs in all content processes searching for applicable content). If this ends up being a problem, two ideas come to mind: 1. We could hold some kind of weak list of pages that are at URLs in the whitelist, and iterate through those instead. We'd need to manage that whitelist, and that might add a bit of memory overhead - space/time trade-off there. 2. We could break up this loop to occur in one or more idle ticks. Any performance impact here is speculation, though. Let's not prematurely optimize - let's see how much this actually impacts things in practice. ::: browser/modules/LightweightThemeChildHelper.jsm:50 (Diff revision 7) > - } > + } > + }, > > /** > * Forward the theme data to the page. > - * @param {Object} data The theme data to forward > + * @param {Object} outerWindowId The outerWindowId the parent process window has. nit: outerWindowID for consistency. ::: browser/modules/LightweightThemeChildHelper.jsm:53 (Diff revision 7) > /** > * Forward the theme data to the page. > - * @param {Object} data The theme data to forward > + * @param {Object} outerWindowId The outerWindowId the parent process window has. > * @param {Object} content The receiving global > */ > - _update(data, content) { > + _update(outerWindowId, content) { Let's just call this update, since it's called by an external consumer.
