* Long live QStringView!Marc Mutz2017-03-241-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | QStringView is a simple container for (const QChar*, int) and (const char16_t*, size_t). It acts as a replacement interface type for const QString and const QStringRef, and enables passing all kinds of string-like types to functions otherwise expecting const QString& - without the need to convert to QString first. The use of this new class is guarded by a macro that enables three levels of QStringView support: 1. offer QStringView, overload some functions taking QString with QStringView 2. like 1, but remove all overloads of functions taking QStringRef, leaving only the function taking QStringView. Do this only where QStringRef overloads tradionally existed. 3. like 2, but replace functions taking QString, too. This is done in order to measure the impact of QStringView on code size and execution speed, and to help guide the decision of which level to choose for Qt 6. This first patch adds QStringView with most of its planned constructors, but not much more than iterators and isNull()/isEmpty(). Further patches will add support for QStringView to QStringBuilder, add QStringView overloads of functions taking QString, and add the complete API of const QString to QStringView. [ChangeLog][QtCore][QStringView] New class, superseding const QString and QStringRef as function parameters, accepting a wide variety of UTF-16 string data sources, e.g. u"string", std::u16string{,_view}, and, on Windows, L"string", std::wstring{,_view} without converting to QString first.

* Use fromUtf8() instead of fromLatin1() for QT_RESTRICTED_CAST_FROM_ASCIIhjk2017-03-211-1/+1
| | | | | | | | | | | | | | The change does not change legally observable behavior as the result of using QT_RESTRICTED_CAST_FROM_ASCII is only defined for (a part of) the 7-bit range where Latin1 and UTF-8 are the same. This change does not intend to lift the 7-bit restriction on string literals for which the use of QT_RESTRICTED_CAST_FROM_ASCII is well-defined even though in practice it works now for any UTF-8, which is the presumed encoding outside that range nowadays.

| * Deprecate QString::nullMarc Mutz2017-03-121-1/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It's a Qt 3 compatibility vehicle, and as such inherits the now-alien property to distinguish empty and null strings. Particularly worrisome is the following asymmetry: QString("") == QString::null // false QString("") == QString(QString::null) // true Instead of fixing this behavior, recognize that people might use it as a weird way to call isNull(), albeit one that once was idiomatic, and simply deprecate everything that deals with QString::null. [ChangeLog][QtCore][QString] QString::null is now deprecated. When used to construct a QString, use QString() instead. When used to compare to a QString, replace with QString::isNull().

* | Make Q_ASSERT() usable in constexpr functionsMarc Mutz2017-03-161-5/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We need Q_ASSERT in (C++11) constexpr functions, and the only way to inject them in C++11 is to use the comma operator. E.g. in QLatin1String: constexpr QLatin1Char at(int i) const { return assert(1 >= 0), assert(i < size()), m_data[i]; } The main problem with our existing Q_ASSERT is that while it is a ternary expression in active mode, it was a statement in passive mode. This is easily fixed by dropping the do-while loop and leaving just its parenthesized exit condition. Add a cast to void, too, ensuring that Q_ASSERT has type void in both passive and active modes. But even in C++14 constexpr functions, which accept several statements, Q_ASSERT needs to have a path through its conditionals that is constexpr, but neither qt_assert(_x) nor qt_noop() are constexpr. Nor can they be in C++11 (no void returns in C++11 constexpr functions). I fixed this by replacing qt_noop() with static_cast<void>(0). The void cast is required so both 2nd and 3rd arguments to the ternary are void (mixing void and non-void branches in the ternary is only allowed if the void leg is a throw-expression[1]). As a drive-by, adjust to style guide, remove overparenthesization and reverse the conditional in the ternary. Apply it to QLatin1String where we had the problem that constexpr functions had a narrow constract. [1] should probably be extended to any [[noreturn]] void function, e.g. std::terminate(). [ChangeLog][QtCore][QtGlobal] Q_ASSERT() and Q_ASSERT_X() now always expand to expressions of type void that are usable in constexpr contexts. This makes them usable in both C++11 and C++14 constexpr functions.

Apart from MSVC 2013, all our supported compiler also support char16_t: - VxWorks uses GCC 4.8, which supports char16_t since 4.5. - ICC supports char16_t since v12.1; we require v14+. - ONX uses a GCC which supports char16_t in the compiler, but is equipped with a stdlib that does not sport char16_t support, which is why we revoke its Q_C_UNICODE_STRINGS in qcompilerdetection.h. But we don't need stdlib support, we only need the core language feature. This is the only platform where this patch actually changes something. It removes the, rather unfair, pessimization of the platform which could have supported the static-storage- duration implementation of QStringLiteral instead of the fallback, which uses dynamic memory (QString::fromUtf8()). - GCC and Clang support char16_t since 4.5 and 3.0, resp., which is far below our minimum compiler requirements in effect since Qt 5.7. - On Windows, MSVC supports char16_t since 2015 only, and we still support 2013, but on Windows, wchar_t is the same size as char16_t, so instead of u"str" we can fall back to L"str". So simplify the implementation of QStringLiteral by assuming that all these feature are present, adding noexcept to the lambda to make noexcept() queries return true. This allows us to guarantee: [ChangeLog][QtCore] QStringLiteral is now guaranteed to be evaluated at compile-time. The last platform (QNX) to use the QString::fromUtf8() fallback has been ported to allocate the string data statically, too.

It broke too many users, even though all of them deserved to be broken. The new functionality will be provided by differently-named functions, where possible (problem: equality operators). I did not revert the fix for the off-by-one error in tst_qtextdocumentfragment.cpp. I also didn't revert the change in the inequality relational operators, since for all strings s1, s2 and s2' where s2' is s2 truncated at the first NUL, s1 < s2 ⟺ s1 < s2' (since NUL < c for any c != 0), and, trivially, for ≤, >, ≥, too. This does not hold for = and ≠, of course, since "foo\0bar" ≠ "foo".
