* Client: Always close popups when hiding a windowJohan Klokkhammer Helsing2020-01-041-2/+1
| | | | | | | | | | | | | | | | It's not just popups that may have popups open on them. Always close open popups when hiding a window to prevent dangling pointers.

| | | | | | | | | | | | | | | Previously, we set the max length in QString character length, which means UTF-16 characters (of potentially three bytes) counts as one character. The max limit of libwayland, however, is in bytes (and the string itself is converted to UTF-8).

Therefore, the sizes of objects did not match between the client code that calls new and the constructor inside Qt. Unfortunately, adding the additional members breaks binary compatibility. This has already happened between 5.11 and 5.12. It just wasn't apparent from the headers. If we removed the members again now, we would break binary compatibility again. Therefore, the best course of action seems to be acknowledging the break and adding the members also in the headers. [ChangeLog][Compositor][Important Behavior Changes] Between version 5.11 and 5.12 binary compatibility for the wayland compositor module was broken by adding an additional member to various classes. This was not apparent from user code as the member was behind an #ifdef which would only be set while compiling Qt. As several versions of Qt incompatible to 5.11 have already been released now, rolling back the incompatible change would introduce further incompatibility. Therefore, the change is made consistent by unconditionally adding the member to the headers.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This race happened because QWaylandIntegration::clientBufferIntegration (which lazily initializes the integration) was called from numerous places including code that may run on different threads without any kind of syncrhonization. An example of this is Qt3D, which indirectly and simultaneously calls createPlatformWindow (from the GUI thread) and createPlatformOpenGLContext (from its render thread), both of which needs to use the client buffer integration. In this patch, we fix it by first checking if the integration is initialized. In that case, it's safe to use it. Otherwise we lock a mutex, re-check if initialization has happened on another thread in the meantime, and then finally we initialize it. This way we should avoid the expense of mutex locking after initialization is complete, while still staying race free during initialization.

* | Client: Emit wl_surface lifetime signals on QWaylandWindowJohan Klokkhammer Helsing2019-08-192-1/+9
|/ | | | | | | | | | | | | | | | | | | | | | | Recent changes in QtBase means QtWayland will have to follow the convention of the rest of the QPA plugins and have QPlatformSurfaceEvent::SurfaceCreated and SurfaceAboutToBeDestroyed follow the QPlatformWindow (QWaylandWindow) lifetime and not the lifetime of wl_surface. Some users were depending on those events to get notified about wl_surface changes and used QPlatformNativeInterface in order to get the window's underlying wl_surfaces in responses to the events. The good news is that QPlatformNativeInterface is private (QPA) API, so we can provide an alternative by exposing new private API, which is what this patch does. The QWaylandWindow::wlSurfaceDestroyed signal already exists in the dev branch (introduced in eb66211ea9), so this is a backport of that signal as well as an addition of a new QWaylandWindow::wlSurfaceCreated signal.

This patch makes sure we return the premultiplied variants for ARGB8888, as well as for ABGR8888. Using a switch instead of the array also allows us more freedom to choose the preferred format in other cases where multiple QImage formats map to the same wl_shm format. While being wrapped and exported as QtWaylandClient::QWaylandShm::fromFormat (private API), this conversion function doesn't seem to be used anywhere, so this patch shouldn't cause any changes in behavior for projects that only use public API.

* Client: Full implementation for frame callbacks (second try)Johan Klokkhammer Helsing2019-04-247-49/+218
| | | | | | | | | | | | | | | | | | | | | | | | | The Wayland plugin now takes full control over delivering update request and implement frame callbacks for both egl and shm. [ChangeLog][QPA plugin] The non-blocking version of eglSwapBuffers is now used, if supported. This fixed a bug where minimized windows would block the event loop. [ChangeLog][QPA plugin] Windows that don't get frame callbacks from the compositor within 100 ms are now set as not exposed. This should stop most clients from rendering unnecessary frames to minimized or hidden windows. Also, when we relied on the QPA version of requestUpdate, we would sometimes deliver one update request while we were waiting for a frame callback. When we implement the fallback timer ourselves we can make sure we only deliver the fallback if there are no pending frame callbacks. QtQuick and other applications often depend on blocking swapBuffers to throttle animations. If the context's surface format has a non-zero swapInterval, try to emulate a blocking swap.

* Compositor: Call eglUnbindWaylandDisplayWL when destroying the compositorJohan Klokkhammer Helsing2019-03-142-0/+11
| | | | | | | | | | | | | | | If unbind is not called, some drivers may try to do cleanup that depends on a valid wl_display in eglTerminate. Arguably, this could/should also have been fixed in the affected drivers. There is a display_destroy signal that the driver should listen to, to avoid using dangling wl_display and wl_global pointers. However, by using eglUnbindWaylandDisplayWL we can force the cleanup to happen before wl_display_destroy. Which is what this patch does.

* Client xdg-shell: Fix crash when switching popupsJohan Klokkhammer Helsing2019-02-124-9/+19
| | | | | | | | | | | | | | | | | | | | | | | | The call to flushWindowSystemEvents() sometimes caused new popups to be shown in the middle of hiding another. I.e. if multiple events show and hide surfaces, they would be shown/hidden in opposite order of their corresponding events. QMenus sometimes suffered from this (can be seen with the qopenglwidget example from qtbase). When the flush was added 5 years ago in 50f43a0c5, it was to "reduce the chances of seeing a bad frame". I don't see any rendering artifacts, though, and I can't find any bug report on it. So let's hope it's safe to remove the hack. [ChangeLog][QPA plugin] Fixed a crash that sometimes happened when switching popups. Also adds more info to the workaround warning message that appears when a popup grab is attempted and there already is another grabbing popup that is not the parent.

We probably need to emulate a blocking swapBuffers and continue after a timeout, but until we have a patch for this, revert this to avoid releasing a regression. This brings back the bug with a frozen event loop when a surface is waiting for a frame callback, but this is preferable to a regression. This reverts commit 1dc85b95ab0adc1e805d059e2c35c671ef790011.
