Steps to reproduce: 1. Bookmark http://blogs.yahoo.co.jp/alice0775/31315844.html And make sure it should open in Sidebar(i.e Check "Load this bookmark in the sidebar") 2. Open the bookmark 3. Click a link "https://github.com/alice0775" in Sidebar panel Actual Results: New tab open, but no content. Expected Results: New tab open, and content should display.

Blocks: old-e10s-m2
Hey Brad, Here's another bug that I'm not sure should be in M2. Opening links from the bookmarks sidebar works - the problem seems to be opening window.open or target="_blank" links with content that is loaded in the sidebar (you can choose to have links open within the bookmarks sidebar). That, to me, sounds like an edge-case, and not necessarily something that should block M2. Am I good to remove this from the M2 list, or should we discuss this on Thursday? -Mike
Flags: needinfo?(blassey.bugs)
This is actually a very specific case of a more general problem, in that non-remote tabs in e10s windows can't currently open window.open or target="_blank" links. This means that any URI's that are remote-tabs blacklisted (any about: pages that are not about:blank or about:home) will not have working window.open or target="_blank" links. That sounds kinda bad. Still not sure if it's M2, though.
Summary: [e10s] Contents does not load when I click a link in sidebar panel → [e10s] Non-remote tabs in e10s windows do not handle target="_blank" or window.open links properly.
let's renom and discuss in triage
Flags: needinfo?(blassey.bugs)
We decided in triage yesterday to take this off the M2 list.
No longer blocks: old-e10s-m2
So I _think_ this will work. This does two things: 1) This makes it so that in nsAppShellService::JustCreateTopWindow, if we have a parent context that is loading a new window, that we ensure that the parent context has UseRemoteTabs set to true AND that an opening tab was passed in. This means that if we have a non-remote tab in an e10s window, opening a popup window from that tab will result in the new window not being remote. 2) All calls to nsBrowserAccess::OpenURI results in a browser that is not remote. That means that if we attempt to open a new window or tab from a link (or even if the user prefs override those behaviours and load that link in the current window), and that link is coming from a non-remote tab, then it will result in the new browser also being non-remote. #1 is straight forward, but #2 is something I want to check out a bit more. Right now, I can only find nsBrowserAccess::OpenURI being called from nsContentTreeOwner, which implies being opened from a non-remote browser (regardless of whether or not it's in an e10s window or not). I want to check any other callers of that method to make sure that I'm not introducing any weird side-effects here.
Comment on attachment 8485883 [details] [diff] [review] Make it possible to load new windows from non-remote browsers within an e10s window. r=? Hey billm, I'm a little wary of my change to browser.js. I'm basically forcing any window-opening code that ends up in nsBrowserAccess to result in a non-remote browser. I _assume_ that if we ended up in nsBrowserAccess.openURI in the first place, that we're getting called from nsContentTreeOwner, which implies that the opener is not remote... Is that a reasonable assumption? I can't see how we'd end up in openURI if the opener was remote. If it is reasonable, should I make this assumption more explicit with some asserts? Perhaps assert that aOpener is not a CPOW? Let me know what you think. -Mike

I'm pretty sure the only real reason that we're ever opening new tabs or windows in non-remote browsers (other than because their URL's are blacklisted), is because their openers are also non-remote, and so opener needs to work. > > 2) All calls to nsBrowserAccess::OpenURI results in a browser that is not > > remote.

Can we just add that parameter and > then be sure we're doing the right thing here? As far as I can tell, nsIBrowserDOMWindow::OpenURI _is_ passed the url to be loaded into the new window/tab. I'm not 100% sure I understand what you're suggesting here - perhaps to dynamically choose whether or not to use remote browsers in OpenURI based on the URI? I think the problem there is that in the new tab case, OpenURI attempts to return browser.contentWindow, which is undefined for remote browsers. We could naively use browser.contentWindowAsCPOW, but I'm extremely wary of passing CPOW's around, especially back to native callers. Things explode that way.

So the url isn't passed (the URL parameter is null because the caller wants to handle the load: http://mxr.mozilla.org/mozilla-central/source/xpfe/appshell/nsContentTreeOwner.cpp#903). So we open a remote tab by default I think because a null URL implies about:blank. I wanted us to set remoteness based on the real URL rather than making the assumption. But yeah if a remote browser is unusable then that won't help. What should happen is that if you land this then bug 999239 will force us to re-create the browser as a remote browser when necessary what the caller initiates the load.

Can do.
It would be better to avoid CPOWs even in tests. Our long-term goal is to eliminate them, so there's no point in adding more.
Thanks for the reviews! Fixed issues raised by billm and Mossop, landed as: remote: https://hg.mozilla.org/integration/fx-team/rev/dc6a44c16a37

Something is up with my test. When fx-team re-opens, I think we should keep the fix, but back out the test until I can fix it.
Ah, I think I know what's up - this test opens an e10s window to do its testing in. That's totally not supported on Linux without OMTC on, and we show a prompt to that effect if someone attempts to open an e10s window. So I suspect this test just needs to be disabled on Linux until OMTC defaults to on.
Landed patch to disable test on Linux: remote: https://hg.mozilla.org/integration/fx-team/rev/1e0e069b5cc7 Filed bug 1066856 to re-enable the test once OMTC is enabled by default on Linux.

Sorry about the kerfuffle, folks. I'll be looking at alternatives today.
Ok, my alternative proposal: Instead of unilaterally passing aEnsureNonRemote as true from openURI, instead only set that to true if the following conditions are met: 1) aOpener exists 2) aContext is nsIBrowserDOMWindow.OPEN_NEW If aOpener exists, then by the time we call openURIInNewTab, it must not be a CPOW, so we must be opening from a non-remote browser, meaning that we care that that the newly created browser is also non-remote. Making sure aContext is OPEN_NEW is more of a sanity check - I can't think of a single scenario where we'd want to call OpenURI with OPEN_EXTERNAL and pass an opener. Every instance of OpenURI I can find where OPEN_EXTERNAL is set as the context has aOpener set to null. And that, I think, makes sense - what would a new tab or window opened by an action from an external source pass as an opener? The external source itself? It's kinda non-sensical. I also think I've found some already-existing tests that would have caught but 1067164, but weren't enabled for e10s. I'm going to see if we can get those enabled for e10s.

The reason it was disabled was because the isBusy property on XULBrowserWindow is not synchronously set to true. Also, just waiting for the condition to be true is unlikely to work, as the page we're loading is so small, that it's more likely for isBusy to switch from true back to false before waitForCondition is able to notice that it was ever true. I could add some kind of wrapper function around the isBusy setter, and monitor for it flipping around, but I'm not entirely sure checking for isBusy adds much in the way of value to this test. Dao, you wrote this test - is there much value in keeping the isBusy check?

I'm concerned because it means running web content in the main process still in some cases and I'd like to understand why that is necessary. You mentioned window.opener, but I very much hope that the web content's window.opener can't refer back to the privileged page that opened it.

Comment on attachment 8491707 [details] [diff] [review] Part 2: [e10s] Re-enable browser_bug562649.js for e10s windows I don't think the XULBrowserWindow.isBusy check is crucial to this particular test, but at the same time I'm worried that XULBrowserWindow.isBusy could be subject to the same problem when used in production code, in which case removing this from tests would be weird. Someone probably needs to audit the code using isBusy.

So after a conversation with Mossop, this bug might actually get taken care of by his work in bug 999239. That bug adds some support in DocShell for developers to hook into a document load request. Firefox can then hook in, and check the URI to be loaded against the blacklist to see whether or not the browser should be remote or non-remote, and then ensure that the browser is in the correct state before kicking off the load of the page. If it works as advertised, that will mean that opening links from about:crashes, for example, will result in the browser safely transitioning from non-remote to remote, and that'll eliminate the need for us to allow non-remote browsers to be opened from non-remote browsers in e10s windows. I'm going to test Mossop's patch in bug 999239 to be sure, but I have a good feeling.

So, the good news is that Mossop's patch fixes the case where we've transitioned a blacklisted page to a non-blacklisted page (say, about:crashes to a crash report on crash stats), and letting us open popups / new tabs from that page. So that's good. The bad news is that this doesn't fix the following cases: 1) Blacklisted pages opening new tabs / windows directly 2) Opening new tabs or windows from the bookmarks sidebar browser, which was the reason this bug was originally filed, still doesn't work properly.
Hey Mossop, so regarding (1) and (2) in comment 53 - am I right in assuming that both of those cases are less serious than our original about:crashes-transition case? For example, I'm trying to find an about: page that opens a new tab or window directly either with window.open or _blank, and dxr isn't showing any hits. I do believe, however, that we don't want to regress the behaviour of the sidebar. I guess what I'm suggesting is, with your work in bug 999239, I believe we can probably downgrade the priority of this bug, as both the (1) and (2) cases sound really edge-casey to me. Do you agree?
Flags: needinfo?(dtownsend+bugmail)
I agree, any main UI that is opening links should really be using openUILink, about:preferences does that, maybe about:crashes should too but that has other peculiarities. For the specific case of web content loaded in the sidebar I think this goes back to tracking+.

Hey smaug, So this last patch seems to fix things for the case where we're opening a target="_blank" or window.open link from a non-remote tab in an e10s window. It, however, is pretty horribly broken if we attempt to do this with browser.link.open_newwindow set to 2 (so that we open links in new windows instead of new tabs). Here's what happens in that case (STR here[1]): https://www.dropbox.com/s/zqhpdolteycj1pa/Screenshot%202015-01-12%2017.30.36.png?dl=0 The content gets loaded into the chrome docshell. :/ The code that does it is in here in nsWindowWatcher::OpenWindowInternal: if (newChrome) { /* It might be a chrome nsXULWindow, in which case it won't have an nsIDOMWindow (primary content shell). But in that case, it'll be able to hand over an nsIDocShellTreeItem directly. */ nsCOMPtr<nsIDOMWindow> newWindow(do_GetInterface(newChrome)); if (newWindow) GetWindowTreeItem(newWindow, getter_AddRefs(newDocShellItem)); if (!newDocShellItem) newDocShellItem = do_GetInterface(newChrome); if (!newDocShellItem) rv = NS_ERROR_FAILURE; } The problem is that we're not getting newWindow from newChrome - GetInterface is failing. The reason that GetInterface is failing is that the initial browser is being forced to be non-remote during the loading of the window, right here: http://hg.mozilla.org/mozilla-central/file/cac64af410a1/browser/base/content/browser.js#l912 Forcing non-remoteness removes the DocShell, which clears out the mPrimaryContentShell from the nsXULWindow, and that mPrimaryContentShell is what we look to in order to GetInterface an nsIDOMWindow from newChrome (which is an nsContentTreeOwner in this particular case). And the reason we do that setting of the remoteness of the initial browser in the onLoad function is because the code I added in bug 989501 wants to have new windows opened from remote tabs to have a remote browser in it right away so that we can pass the PBrowser back to the caller synchronously. So the story is: If I want to take advantage of Mossop's patch, I need to make it so that the initial browser of a newly opened window or tab is non-remote. But that breaks the assumption when we open a new window from the content process, which wants to have the initial browser be remote. Do you have any suggestions on how I might approach this? [1]: STR 0) Apply patch 1) Set browser.link.open_newwindow to 2 2) Open about:welcomeback in an e10s window 3) Click on the "learn more about what you can do" link

Comment on attachment 8548354 [details] [diff] [review] Part 2: Make TabParent::AnswerCreateWindow force the initial browser to be remote in a new window So here's my solution to the problem I mentioned in comment 83. TabParent::AnswerCreateWindow was expecting the window to stash a remote browser into the new window's docshell - it was using GetOpenedRemote to get a handle on that. I'd added that code in bug 1021466. This alters that approach somewhat. We make it so that every window starts with the initial browser not being remote. We expose a method on nsIXULBrowserWindow to force the initial browser to be remote and return the nsITabParent associated with it. We call that function from AnswerCreateWindow, and bob's your uncle. This way, other code that relies on a new window having an mPrimaryContentWindow is going to get that requirement satisfied - and Mossop's patch from bug 999239 allows the browser to decide whether or not the URI we're going to really should be in a remote browser or not. What do you think of this solution, smaug?

https://reviewboard.mozilla.org/r/2463/#review2503 Hey Mossop, I'm requesting review on this one from you now because I've altered it to move the Browser:LoadURI message handler to onLoad instead of onDelayedStartup. In my regression test (the one later in this review series), I noticed that when opening new e10s windows from non-remote tabs, that the Browser:LoadURI message would get fired before onDelayedStartup was called, so the message was never handled. I'm only kinda understanding how this redirect-load stuff works, but I moved the message handler into onLoad, and had RedirectLoad call LoadInOtherProcess after a tick of the event loop to give onLoad a chance to finish initialization before redirecting. Am I way off the rails with that?

Moving registering the message handler to onLoad makes sense, the rest doesn't. Even though we register the message handler we can be guaranteed that RedirectLoad won't be called before onLoad finished executing. Now the question becomes is it safe to call RedirectLoad before delayedStartup has run. I don't know. It might be safest to check if it has run and if not wait for that.

Comment on attachment 8548471 [details] MozReview Request: bz://1047603/mconley Hey Mossop, I've corrected the first patch in this review series to call LoadInOtherProcess after _delayedStartup, even if the message was received before _delayedStartup was called. Mind giving this another look? Here's the interdiff: https://reviewboard.mozilla.org/r/2463/diff/3-4/

https://reviewboard.mozilla.org/r/2993/#review2573 > I tried reading the other patches but I don't understand why the behavior changes now so that we "restore" the initial tab? I'm not too worried about the test, more about the general behavior that seems a little strange? Mossop's work in bug 999239 makes it so that when we transition from a non-remote browser to a remote browser (or vice versa), we preserve history by causing a "restore" after the transition. This patch series changes the assumption of having the initial browser in an e10s window being remote. nsWindowWatcher::OpenWindowInternal expects to be able to get a handle on the mPrimaryContentTreeOwner of a XULWindow to send to the URL that the user is trying to open. It used to be the case that for e10s windows, we'd force the initial browser to be remote in onLoad, so that by the time nsWindowWatcher tried to get the mPrimaryContentTreeOwner... no such owner would exist. So now with this patch series, we don't force the initial browser to be remote (except in two cases - see /r/2465 that smaug reviewed, and /r/2469 that Mossop reviewed). Instead, we let the work in bug 999239 take over, so that once the browser attempts to go to a URL, it decides whether or not the browser should be remote (almost always yes), and then transitions that browser to become remote, which causes it to "restore". Admittedly, there might be little value in attempting to "restore" a tab that has just transitioned when the previous state was about:blank having not traveled anywhere. But I think maybe that's a separate bug. Does that make it clearer?

I think there is some improvement to be made to nsWindowWatcher at some point. If all it needs to do is to be able to load a URI into the new tba then it seems like there is a different way we could let it do that. Follow-up fodder I think though. > Admittedly, there might be little value in attempting to "restore" a tab > that has just transitioned when the previous state was about:blank having > not traveled anywhere. But I think maybe that's a separate bug. Yeah, if all the current session history is marked unpersisted (about:blank is) then restoring is kind of silly

https://reviewboard.mozilla.org/r/3461/#review2771 Hey ttaubert - I hit another one of these when I land/bounced. Similar story as https://reviewboard.mozilla.org/r/2993/, I'm afraid. :/
https://reviewboard.mozilla.org/r/3459/#review2777 Ship It! ::: testing/marionette/marionette-server.js (Diff revision 1) > + } This looks like the right work around until bug 1096488 is fixed. I'm not sure about your commit message, though. Marionette is using the globalMessageManager and keeping in touch with a particular frame script to run commands in content based on an outer window ID. As I understand the problem with remoteness changes and marionette, the underlying window/frame script is replaced without marionette's awareness, so further commands are lost. That being said, I may not fully understand that situation yet, but bug 1096488 is on my todo list, so if you've seen anything to the contrary when looking into this, that would be very interesting to me. Thanks!
