* CoreText: Warn the user when family alias lookup slows down the applicationTor Arne Vestbø2019-10-084-8/+48
| | | | | | | | | | | If the user specifies a font family in their application that doesn't exist in the system, or one that uses the localized family name, we will end up resolving the family alias for all fonts in the system, which typically adds 600-800ms of startup time. Let the user know when this happens. Change-Id: Id8d6f55028e37f681ec4a686df25d33240b5a30f Reviewed-by: Eskil Abrahamsen Blomfeldt <eskil.abrahamsen-blomfeldt@qt.io>

* QTextCodec: try to work around an ICC 19 bugMarc Mutz2019-10-071-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | ICC 19 barfs on the TextCodecsMutexLocker class because it doesn't have a user-provided default ctor: ../../corelib/codecs/qtextcodec.cpp(543): error #854: const variable locker requires an initializer -- class TextCodecsMutexLocker has no user-provided default constructor [...] But the class doesn't have members that would delete the implictly-declared default ctor, so no user-provided default ctor should be necessary: The only member is the result of qt_unique_lock(), which is std::unique_lock, which does have a default ctor. We conclude that this is a compiler bug, and work around it with the introduction of a user-provided default ctor. Fix brace placement as a drive-by.

* Include likely-adjusted uiLanguages for the system localeEdward Welbourne2019-10-043-16/+68
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | QLocale::uiLanguages() on the system locale uses whatever the system locale's query(QSystemLocale::UILanguages,...) returns. On Android, this is just a list of locales. However, for non-system locales, we also include some results of removing likely sub-tags from the locale name, where equivalent. Thus zh-CN would also get zh and zh-Hans-CN added to it; however, if the system locale is zh-Hans-CN, the shorter forms are omitted. So post-process the system locale list in the same way, albeit tweaked to avoid duplicates and rearranged so that we can insert likely-adjusted entries between what they adjust and what followed it. Added QLocalePrivate::rawName() in the process, since it looks likely to be useful in other contexts (and I needed its value): it just joins such tags as are non-Any. This, however, uses QByteArrayList, so added that (it's small) to the bootstrap library and qmake. This follows up on commit 8796e3016fae1672e727e2fa4e48f671a0c667ba. [ChangeLog][QtCore][QLocale] The system locale's UI languages list now includes, as for that of an ordinary locale, the results of adding likely sub-tags from each locale name, and of removing some, where this doesn't change which locale is specified. This gives searches for translation files a better chance of finding a suitable file.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Forcing users to go through a QVector, when in practice they almost always want to source the data from an initializer list, a QVarLengthArray, or a plain C array, is not ideal. Especially since we can reason about the maximum number of elements in the vast majority of use cases for all the affected lists. QRhiResource is also not copyable so we do not need the usual machinery offered by containers. So switch to a QVarLengthArray. Note that a resource is not a container. The only operations we are interested in is to be able to source data either via an initializer list or by iterating on something, and to be able to extract the data, in case a user wishes to set up another resource based on the existing one. In some cases a QVector overload is kept for source compatibility with other modules (Qt Quick). These may be removed in the future. Also do a similar QVector->QVarLengthArray change in the srb-related data in the backends.

However, as binary compatibility will not be a concern for QRhi classes, it is wasteful to allocate memory on every QRhiShaderResourceBinding. This allows users, such as Qt Quick, to use QRhiShaderResourceBinding as a cheap, simple, value class, without having to invent their own alternatives in performance critical places. The change brings a not insignficant improvement in certain qmlbench scenes (the ones with thousands of unbatched geometry nodes).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some AMD CPUs (e.g. AMD A4-6250J and AMD Ryzen 3000-series) have a failing random generation instruction, which always returns 0xffffffff, even when generation was "successful". This code checks if hardware random generator generates four consecutive equal numbers. If it does, then we probably have a failing one and should disable it completely.

| | * iOS: Fix fallback fonts on iOS 13+Eskil Abrahamsen Blomfeldt2019-09-262-0/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since iOS 13, the cascade list for the default UI font contains meta-families for several writing systems, such as CJK. Since these font families were never populated to the database, we ignored them in Qt, and thus got missing glyphs for the characters in question. The fix is to make sure these fonts are populated in the database. It contains a partial backport of 922d195020d54d7e599d135f6a5e0338100e08f1, which adds the qt_isFamilyPopulated() accessor to allow us to check if the family has been populated in the font database. In Qt 5.14, there is public API for this in QPlatformFontDatabase, so this is a temporary resolution until then.
