[PATCH v6 0/7] MR4380: mshtml: Keep inner window's link to the outer window until it's destroyed.
Here's a list of usages of `base.outer_window` that may be impacted by the change and my analysis/fixes. Note that I specifically did not look for `document->outer_window` since that one was already holding it forever, so it's out of scope for this MR (whether it's correct or not, the behavior is the same after this MR). I also didn't consider some cases that already **did not check** for it being NULL or not, because they would have crashed earlier before anyway (they'd still crash now if outer window gets killed, but it's out of scope of the MR as I said). For those that says "Handled" it means I've added checks so that the behavior is same as before, i.e. detached inner windows behave as if outer window is NULL. * `htmldoc.c/HTMLDocument_get_mimeType`: Changed so it doesn't rely on outer window. * `htmldoc.c/HTMLDocument7_get_defaultView`: This is actually fixed by these patches. * `htmlform.c/HTMLFormElement_submit`: Handled. * `htmlstorage.c/send_storage_event`: Fixed in a separate patch with tests, since it follows the outer window. * `htmlwindow.c/check_target_origin`: This (along with many other methods) can't have it NULL anymore or detached, since the caller must hold a ref to the outer window, and they're not called from our objects holding ref to inner window only. * `htmlwindow.c/HTMLWindowSP_QueryService`: This uses the outer window to obtain the browser and the doc obj, so it's fine. * `mutation.c/set_document_mode`: Handled. * `navigate.c/BindCallbackRedirect_Redirect`: Handled. * `navigate.c/nsAsyncVerifyRedirectCallback_OnRedirectVerifyCallback`: Handled. * `navigate.c/nsChannelBSC_init_bindinfo`: Uses the outer window to obtain the browser and doc obj to set a flag, so it's harmless and probably correct this way. * `navigate.c/handle_navigation_error`: Handled. * `navigate.c/handle_extern_mime_navigation`: Handled. * `omnavigator.c/OmHistory_get_length`: This is actually fixed by these patches. * `script.c/ActiveScriptSite_GetItemInfo`: Handled. * `script.c/ActiveScriptSiteWindow_GetWindow`: Handled. -- v6: mshtml/tests: Fix XHR leak in test_window_refs. mshtml: Get rid of outer_window member in HTMLDocumentNode. mshtml: Remove the inner window ref from the doc only when it is actually mshtml: Don't check for NULL outer_window from within HTMLWindow* methods. mshtml: Don't attempt to send storage events after outer window is detached. mshtml/tests: Improve the iframe navigation test. mshtml: Don't rely on the outer_window in document.mimeType. https://gitlab.winehq.org/wine/wine/-/merge_requests/4380
From: Gabriel Ivăncescu <gabrielopcode(a)gmail.com> This would have crashed on detached windows, and checking the navigation_start time has the same effect except it's decoupled from the outer window.

From: Gabriel Ivăncescu <gabrielopcode(a)gmail.com> It was confusing before since it made it seem like it might use the outer window, while in fact the document is unchanged on native. Now the "new" doc is used for navigating, since it's already checked to be the same as the iframes_doc (but that test fails in wine and is todo_wine).

Well nevermind, I removed that patch for the moment to get this going. If you were reviewing it, I did not mean to waste your time—I will happily send it after this MR, just let me know if you want/changed your mind please. The goal of that patch was never to change any existing behavior, except for the 3 cases **I tested** (and thus were "fixed" by it). BTW would you have felt more comfortable if I introduced a new `outer_window` field in the inner window without touching the base's and only using it in the 3 cases I tested for, and then merged it with base.outer_window in a separate patch **as a no-op**? That was basically my intent after all. Anyway do let me know if anything changed so I can send it after this MR at some point, even after code freeze if that's fine. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/4380#note_54404
This is still not reviewable in its current form. Neither I nor you can know what's the correct solution without doing the research. Saying that you will do the research only if I promise to accept one or another patch just doesn't make sense. It all depends on outcome of the research; until we have enough information we need to keep it open minded. Claiming that it's not needed because you're interested only in a few random tests also doesn't make sense when you change data structures used module-wide (it's even worse when tests themselves are questionable). Doing code changes like that is easy, the hard part if figuring how to do that. It's unfair to skip the hard part, refuse to do it when asked and complain that the reviewer doesn't do it for you. It's supposed to be author's responsibility. Anyway, I did that just so we can move forwards, see !4574. What I found is: - On IE9+ it's not even allowed to touch detached document, not even compare it to anything. - In old IE mode any attempt to call such document is an error. - In old IE mode, detached document returns true when it's compared to current document, but still fails on any attempt to call it (unlike the current document). Conclusions: - Arguments like "I need to get it committed because it would be hard to debug if something needs it" are pointless, web pages simply have no way of depending on what you did. - Weird crashes observed are probably a by-product of implementation of old IE modes in native; although those APIs are exposed to C it seems that they are just broken there, so trying to read too much out of it is pointless. - We should probably just error-out somewhere in JS binding layer. That's not a task for now; adding some checks to C variant is still not wrong (they are exposed with C interfaces after all), so that's what I did for now. - Storing outer window for longer than needed is not justified. I hope that explains you why skipping proper research is not a good idea. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/4380#note_54594

The only one that comes to my mind is the `doc->outer_window` change but, it's currently broken because it **does** keep ref to the outer window for "longer than it should" (i.e. goes against what you just said), and even worse it does not even hold any sort of ref, so it can access invalid memory. So all my patch does is make it become NULL when the inner window is detached, isn't that what you suggested?! The storage event patch, again, just does what you suggested: it checks if we're detached and skips sending the event altogether (I did put a FIXME comment, but that's just a comment…). Can you please tell me which patch is so wrong now? -- https://gitlab.winehq.org/wine/wine/-/merge_requests/4380#note_54616

Well as I said, I can easily just get rid of the tests and do the right thing with a comment. Silently dropping events sounds like a bad idea to me, it will make it hard to debug if something broken ever depends on it. And it's not like it's more code, either. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/4380#note_54776

The more I look at it the more I'm convinced that the change to keep outer window reference is not worth it. Storage events seem just outright broken on native, so that's not a good reason. Looking at Gecko, I can see that it does what we currently do and resets outer window pointer from inner window and document when inner window changes. It means that whatever we do on Wine side, everything that depends on Gecko will still not "work". The change is also quite invasive. It changes a meaning of pointers that are used module-wide, so there is some risk associated with it and the motivation seems questionable to me. Why do you need that in the first place? This is not something you've actually seen mattering for real-world use case, right? Another thing about it is that it's likely to hide some problems in the future. Resetting outer pointer is nice to have a clear cut when inner window is no longer valid. It's not a strong argument, if we really have a reason to change it, we may, but I'd like to know the reason. Well that's why I wanted it before code freeze, so any possible regressions are detected now. Isn't that the point?
For storage events, yeah I can easily get rid of the test and just keep the current "correct" behavior with a comment. I'd rather keep that than silently drop events (or even if it's logged, it's not that obvious), because that's 1) incorrect and 2) it's extremely hard to debug if something broken ever depends on it. Plus, it's not like sending the events is extra code than silently dropping them, most of the patch is in the tests. As for the "hide problems in the future", I actually think the exact opposite. Right now, we use the document's outer_window in same way, except it's completely broken and can access invalid memory if the outer window happens to die, which would be very hard to debug (especially considering most apps using mshtml are bloated and slow with millions of frameworks). What problem would this hide? The things that *are* different than before (e.g. parentWindow), are tested so they're fixed and correct, with the others being same as before, except not randomly crashing in some cases. Maybe it's not by itself a strong argument, but outer_window on document is now just simply broken and I'd like to fix that before the code freeze. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/4380#note_54777

I mean it's known to be full of bugs and security exploits, to the point of becoming a meme. I could test it if I can use it from JS (actually, can't event handlers still be called after navigation on the old doc/window?), because it would be a silent "failure" or event firing which would be insanely hard to debug otherwise, especially since you can see event handlers are registered and all.
I wouldn't mind trying to test this out, even if it doesn't end up as proper wine tests, I just don't want it to be a waste of time, like it feels right now, even though I was expecting matching native behavior (and fixing potential memory hazards) to be a goal. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/4380#note_54779

The storage event patch, again, just does what you suggested: it checks if we're detached and skips sending the event altogether (I did put a FIXME comment, but that's just a comment…). Can you please tell me which patch is so wrong now? The latest push had the same problem as previous ones: it lacked proper justification based on an analyze. Now that I filled that gap for you, we can move forward. !4574 is not a complete solution, more patches are still needed, please rebase and self re-review taking above into consideration. The patch removing outer_window could be split and misses a number of NULL checks.

The patch removing outer_window could be split and misses a number of NULL checks. I removed that patch for now, I'm looking what to do with it in the meantime and split it (I wish you'd say this from the beginning), but I don't think "avoiding invalid memory access" is lack of a proper justification though, even if the reason was different. I didn't add NULL checks because it didn't have them before, though, so I just wanted to keep same behavior and make it easier to review.
BTW sorry about the comment spam, those are old emails I sent long ago but the email bridge decided to post them now?!? -- https://gitlab.winehq.org/wine/wine/-/merge_requests/4380#note_54873
