This patch fixes the immediate crash, but reveals a more fundamental problem of assuming the platform window that's alive during construction is the one that will always be used with the backingstore.

* CMake: Properly handle CONFIG += thread aka Threads::ThreadsAlexandru Croitor2020-08-063-5/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | mkspecs/features/qt.prf adds a dependency on the system threading library if the Qt Core thread feature is enabled. Because qt.prf is loaded by any public or internal Qt project, it's essentially a public dependency for any Qt consumer. To mimic that in CMake, we check if the thread feature is enabled, and and set the Threads::Threads library as a dependency of Qt6::Platform, which is a public target used by all Qt modules and plugins and Qt consumers. We also need to create a Qt6Dependencies.cmake file so we find_package(Threads) every time find_package(Qt6) is called. For the .prl files to be usable, we have to filter out some CMake implementation specific directory separator tokens 'CMAKE_DIRECTORY_ID_SEP' aka '::@', which are added because we call target_link_libraries() with a target created in a different scope (I think). As a result of this change, we shouldn't have to hardcode Threads::Threads in other projects, because it's now a global public dependency.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ... and QMultiMap as std::multimap. Just use the implementation from the STL; we can't really claim that our code is much better than STL's, or does things any differently (de facto they're both red-black trees). Decouple QMultiMap from QMap, by making it NOT inherit from QMap any longer. This completes the deprecation started in 5.15: QMap now does not store duplicated keys any more. Something to establish is where to put the QExplictlySharedDataPointer replcement that is in there as an ad-hoc solution. There's a number of patches in-flight by Marc that try to introduce the same (or very similar) functionality. Miscellanea changes to the Q(Multi)Map code itself: * consistently use size_type instead of int; * pass iterators by value; * drop QT_STRICT_ITERATORS; * iterators implictly convert to const_iterators, and APIs take const_iterators; * iterators are just bidirectional and not random access; * added noexcept where it makes sense; * "inline" dropped (churn); * qMapLessThanKey dropped (undocumented, 0 hits in Qt, 1 hit in KDE); * operator== on Q(Multi)Map requires operator== on the key type (we're checking for equality, not equivalence!). Very few breakages occur in qtbase. [ChangeLog][Potentially Source-Incompatible Changes] QMap does not support multiple equivalent keys any more. Any related functionality has been removed from QMap, following the deprecation that happened in Qt 5.15. Use QMultiMap for this use case. [ChangeLog][Potentially Source-Incompatible Changes] QMap and QMultiMap iterators random-access API have been removed. Note that the iterators have always been just bidirectional; moving an iterator by N positions can still be achieved using std::next or std::advance, at the same cost as before (O(N)). [ChangeLog][Potentially Source-Incompatible Changes] QMultiMap does not inherit from QMap any more. Amongst other things, this means that iterators on a QMultiMap now belong to the QMultiMap class (and not to the QMap class); new Java iterators have been added.

| | | | | | | | | | | | | | | | | | | | | | | | | | In preparation for the QMap/QMultiMap split. The previous code had a workaround for storing multimaps, because the CF classes actually don't support it: build a dictionary from one key to a _list_ of values. Stop doing that. In principle, if QMultiMap support does get added to QVariant (which it probably should), then a similar workaround could be readded for QMultiMap support. [ChangeLog][Important Behavior Changes][QSettings] On Apple platforms, when using the native format, QSettings is no longer able to handle QVariantMap values which are actually multimaps. Since the native storage does not actually support multimaps, QSettings used to flatten and unflatten the maps. However, with QMap being changed to no longer allow for equivalent keys, flattening when writing does not make sense any more (there cannot be equivalent keys, because QMap in Qt 6 is a single-key map). Reading existing settings is supported by having a key in the map mapping to a QVariantList of values. Support for QMultiMap may be added back to QVariant and QSettings in a future version of Qt.

* wasm: factor visual viewport scale into dprMorten Johan Sørvig2020-08-052-6/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | By default, mobile browsers create a (layout) viewport much wider than the visual viewport in order to be compatible with web pages created with desktop browsers in mind. This means that the default view is zoomed out. This zoom is not reflected in window.devicePixelRatio, and Qt ends up setting the canvas render size to be larger than actually needed. The window.visualViewport.scale property reflects this “mobile” zoom level: add it as a devicePixelRatio factor. (The value will be less than 1 when zoomed out). User pinch-to-zoom may change the zoom level and resize the visual viewport; install a resize handler as well. For now we limit the devicePixelRatio value in order to avoid creating gigantic backing store images - this is something we can revisit later on.

* wasm: set viewport size to device size on mobileMorten Johan Sørvig2020-08-051-1/+8
| | | | | | | | | | | | | | | | | This is a good default, and also works around a couple of current bugs in the Qt implementation. (Applications can change the default values in the .html file as needed.) Change body height to 100% of the visual viewport (“100vh”) to make the html body cover 100% of the viewport after landscape -> portrait transitions on iOS.
