* Purge Q_{STDLIB,COMPILER}_UNICODE_STRINGSEdward Welbourne2020-09-141-4/+0
| | | | | | | | | These were now always defined, hence redundant. Leave the #define in place so that we can verify we actually do always define it, in a #else of an existing #if check on it.

* Long live Q{Any,Utf8}StringView!Marc Mutz2020-08-311-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We need to add these two classes at the same time, because QAnyStringView makes all QUtf8StringView relational operators moot. We might want to add some later, esp. for UTF-8/UTf-8 comparisons, to avoid the pessimization that we can't early-out on size() mismatch in QAnyStringView equality operators, but that's an optimization, not a correctness issue, and can be fixed in a source-compatible way even after Qt 6 is released. To deal with the char8_t problem in C++20, make QUtf8StringView a class template out of which two UTF-8 views can be instantiated: the Qt 7 version, which depends on C++20 char8_t as value_type, and the Qt 6 version where value_type is a char. Use inline namespaces to map the QUtf8StringView identifier to one or the other, depending on the C++ version used to compile the user code. The inline namespace names must needs be a bit ugly, as their inline'ness depends on __cpp_char8_t. If we simply used q_v1/q_v2 we'd be blocking these names for Qt inline namespaces forever, because it's likely that inline'ness of other users of inline namespaces in Qt depends on things other than __cpp_char8_t. While inline'ness of namespaces is, theoretically speaking, a compile-time-only property, at least Clang warns about mixed use of inline on a given namespace, so we need to bite the bullet here. This is also the reason for the QT_BEGIN_..._NAMESPACE macros: GCC is ok with the first declaration making a namespace inline, while Clang warns upon re-opening an inline namespace as a non-inline one.

* Port QLatin1String to qsizetype and add narrow-contract substring functionsMarc Mutz2020-08-231-1/+1
| | | | | | | | | | | | | | | | | | | | | | QLatin1String::mid() etc were changed from narrow to wide contract, but the narrow-contract replacements weren't added. This blocks using the narrow-contract functions in QStringTokenizer. As a drive-by, Q_REQUIRED_RESULT -> [[nodiscard]] and Q_DECL_CONSTEXPR -> constexpr. Also centralize most Q_ASSERT()s in a single function, verify(), in an attempt to reduce the amount of string data generated from the asserts in assertive builds. [ChangeLog][QtCore][QLatin1String] Added from(), sliced(), first(n), last(n) functions. [ChangeLog][QtCore][QLatin1String] size_type/size() is now qsizetype (was: int). This makes QLatin1String(ptr, 0) ambiguous now between the (ptr, ptr) and (ptr, qsizetype) constructors.
