Re: [PATCH v2 0/1] MR2299: wined3d: Do not switch pixel format on non-private GL contexts.
by Paul Gofman (＠gofman) 01 Mar '23

01 Mar '23

Do you see any other way out of this? I mean specifically the case when an app sets GL pixel format itself on a window. I was thinking about whether it is possible to make setpixelformat quicker in winex11 instead and I don't see how. If keeping direct presentation it will require some X window reconfigure which is not going to be anywhere quick. Otherwise, it can be technically made to work like for GL child window redering (keeping composite redirected drawables for different pixel formats) but that requires essentially the same blitting on each present as done with wined3d backup context. The other different (but a bit complicated) way would be to: - count statistics of GL pixel format switches; - introduce switching back from backup context and switch between resetting pixel format or switching to backup context or back based on that. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/2299#note_25906

> It's probably worth pointing out that this has quite some potential for causing regressions in performance. swapchain_blit_gdi() is not fast, and ideally we'd work on reducing the number of cases where it's needed. The fundamental idea here is that setting and restoring the pixel format is even worse, since we always need to recreate the GLX drawable when we do that. And as far as I can tell, this patch doesn't force GDI blitting in any other circumstance. That said, what about Mac? I don't really know what's going on here; set_pixel_format() seems to be cheap, but I can't easily tell if that's because it really is cheap, or because setting the pixel format just doesn't work. Either way this patch is questionable as-is. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/2299#note_25904

[PATCH v8 0/1] MR2153: win32u: Invalidate all cached keys after input.
by Henry Goffin (＠AMZN-hgoffin) 01 Mar '23

01 Mar '23

This patch addresses an issue in Second Life and potentially other multi-threaded applications which process WM_KEYDOWN in one thread and then verify that the key is "still down" with GetAsyncKeyState from another thread. Wine uses a per-thread key cache, resulting in inconsistent views of key status. Caches are now invalidated when an input event is injected by the driver or via SendInput. -- v8: win32u: Invalidate all cached keys after input. https://gitlab.winehq.org/wine/wine/-/merge_requests/2153

[PATCH v6 0/8] MR2098: mshtml: Implement synchronous XMLHttpRequests.
by Gabriel Ivăncescu (＠insn) 01 Mar '23

01 Mar '23

wine-gecko does actually support synchronous XMLHttpRequests, even if they are deprecated, but unfortunately it is very broken compared to IE or all the other major browsers (more details [here](https://bugzilla.mozilla.org/show_bug.cgi?id=697151)). Thankfully, it still provides us with the event message loop, which is enough to fix it on mshtml side and act like IE. For sync XHRs, send() is supposed to block all script code, except for notifications sent to the sync XHR. This is because when send() blocks, no other piece of code in the script should execute other than the sync XHR handlers. Unfortunately, that's not the case in Gecko's broken implementation, which can execute handlers as if they were APCs while it's "blocked" in send(). Note that it doesn't actually block, though, because we still process the message loop (non-event related tasks such as navigation, paints, and other stuff), and that's normal. Gecko doesn't block everything related to script events, only some things on the document and timers, but that's far from enough and not even enough for our purposes since we use our own timer tasks. And not even message events are blocked, even though we *also* use our own message event dispatchers (but it doesn't block Gecko ones either). So what we have to do is we need to track all the timers and events dispatched that result in script handlers being executed, while "blocking" inside of a sync XHR send(), and queue them up to defer them to be dispatched later, after send() unblocks. But this is easier said that done. There are many corner cases to consider here, for example: * Events dispatched *synchronously* from within a sync XHR handler or other piece of code called from it. * Nested sync XHR send() calls (called during handler of another sync XHR). * Async XHRs having their events dispatched during a blocking sync XHR send() are complicated. `readyStateChange` for example needs to have the async XHR's readyState at the time it was sent, **not** at the time it was actually dispatched, since we're going to delay it and dispatch it later. It's similar with other XHR states, such as responseText (which can be partial). * Aborts of async XHRs during such handlers. These patches hopefully should address all the issues and, on a high level, work like this: * Track the `readyState` and `responseText` length manually, so we can override / force them to specific values. * "Snapshot" the async XHR at the time we encounter an event for it, and queue this event with such information. When later dispatching this event (after being deferred), we temporarily set the state of the async XHR to the snapshot. * To deal with nested event dispatches, keep track of a "dispatch depth" (everytime we dispatch an event we increase the depth, and when it returns we decrease it). * For sync XHRs, we note the depth when send() is called, and defer events at that depth, since they're dispatched during the "blocked" message loop and need to be delayed (except for sync XHR events, which is a special case since it must be dispatched synchronously). When it returns, we restore the previous blocking depth. -- v6: mshtml: Send all readystatechange events for synchronous XHRs in IE9 mshtml: Implement synchronous XMLHttpRequest. mshtml: Add separate task list for tasks dispatching events. mshtml: Track readyState in XHRs and report it manually. mshtml: Register all event handlers when creating the XMLHttpRequest. mshtml: Pass optional args to XMLHttpRequest.open() correctly. mshtml: Free the task after the destructor. mshtml: Use proper types for readystate_locked and readystate_pending. https://gitlab.winehq.org/wine/wine/-/merge_requests/2098
