[PATCH v2 0/6] MR4312: mshtml: Return outer windows to external callers and use refs to them.
This fixes some inconsistency issues when it comes to inner vs outer windows. On second patch I keep ref again to outer windows from the inner windows, and there are several reasons for this: * It fixes the existing tests to match native IE. * It simplifies the code (it's always valid now, no second-guessing or what-ifs needed) and gets rid of `outer_window` in HTMLDocumentNode. * It **fixes** the `outer_window` in HTMLDocumentNode → it was basically prone to crashes in niche cases since it didn't hold a ref before. We can't couple it to the inner `window` field either, because that one gets detached, and that will fail *existing* tests. For example: `events.c:3224: Test failed: put_URL failed: 80004005`. * Instead of having to keep outer window refs in specific objects, it's simpler to have it consistent everywhere. -- v2: mshtml: Get rid of outer_window member in HTMLDocumentNode. mshtml/tests: Improve the iframe navigation test. mshtml: Remove the inner window ref from the doc only when it is actually mshtml: Keep the inner window's outer_window pointer alive until it is mshtml: Don't NULL out the doc's window when unlinking the window. mshtml: Return outer window to external callers. https://gitlab.winehq.org/wine/wine/-/merge_requests/4312
From: Gabriel Ivăncescu <gabrielopcode(a)gmail.com> UIEvent.view is still todo_wine because it returns NULL for some reason, but it is clear from the existing tests that it must match the outer window.

From: Gabriel Ivăncescu <gabrielopcode(a)gmail.com> Since we keep the base's outer_window valid until it's unlinked now, we do not need it anymore. Furthermore, it was wrong because it didn't even hold any sort of ref to the outer window...

This is missing `outer_window` NULL check. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/4312#note_51911
The change keeping `outer_window` pointer alive for longer affects tens of NULL checks that we have in the code. Did you actually review the impact? It seems to me that a number of those checks are less correct after the change. I really think it needs closer look and probably some refactoring first so that the change has less impact. I'd suggest dropping all but first two patches for now. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/4312#note_51912

I'd suggest dropping all but first two patches for now. What kind of impact are you expecting? Of course, places where we didn't check for it, are still probably going to crash (there probably are some of them), but that can't be *worse* than before, since it will actually happen less than before.
Is there some code that actually needs to know when it has been detached? I'll try to review all of them but if you know one off the top of your head, it would be interesting to see why. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/4312#note_51930

For example `get_cookie` on a detached document would use URL from another document.
