* QScoped(Array)Pointer: canonicalize swappingMarc Mutz2016-05-041-11/+9
| | | | | | | | | | | | | | | | | | | | This includes: - have nothrow member-swap - have ADL non-member swap - not specialize qSwap or std::swap Also prevent QScopedPointer <-> QScopedArrayPointer swaps by overloading swap (both member and non-member) on QScopedArrayPointer. It's not 100% safe, but it's what we're doing elsewhere (QMulti(Map,Hash), say). That's technically a SiC change if users expected (qualified) std::swap to invoke QScopedPointer::swap(), but those users were doing it wrong to begin with, and they now get a compile-error instead of silent pessimization, because generic std::swap() doesn't work on QScopedPointer, due to lack of copy (and thus move) semantics.

| | * QString: Fix UBs (signed overflow) in hashed string searchMarc Mutz2016-04-261-6/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Similar change to 390ea21873cf229447c2dcaea85a40e472fab03c, but more extensive because the hash variables were not, yet, of unsigned type. This brings the three hashed string search algorithms in QtBase (in QString, QByteArray and QByteArrayMatcher) in line again.

| | * Silence MSVC warnings when using certain std algorithmsMarc Mutz2016-04-263-5/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The MSVC STL warns when passing naked pointers as non-bounded iterators to algorithms such as std::equal and std::copy, in an attempt to inform users that the range specified by that iterator has an implicit minimum size that the caller of the algorithm must ensure is met: warning C4996: 'std::_Equal1': Function call with parameters that may be unsafe - \ this call relies on the caller to check that the passed values are correct. To \ disable this warning, use -D_SCL_SECURE_NO_WARNINGS. See documentation on how to \ use Visual C++ 'Checked Iterators' When building Qt, as well as when building user projects with qmake (cf. 0a76b6bc7f98900ea884cd10ccca1a332e5bdba5), we globally disable this warning (with -D_SCL_SECURE_NO_WARNINGS), but since we started using STL algorithms in public headers (e.g. in qvector.h), users get this warning in their own projects now, unless they, too, define said macro. But such a requirement is against the Qt policy to have headers that are warning-free as much as possible. The suggested way of fixing this warning is to wrap the naked pointer in a stdext::unchecked_array_iterator before passing it to the algorithm, cf. examples in https://msdn.microsoft.com/en-us/library/ttcz0bys%28v=vs.120%29.aspx or, together with the capacity-made-explicit, in a stdext::checked_array_iterator. To avoid ifdefs for platforms that don't have these extensions (which, incidentally, for the unchecked case, includes MSVC 2012), wrap the calls in macros. The end game here is to drop -D_SCL_SECURE_NO_WARNINGS, at least for public headers, even though this commit also adds the wrapper to implementation and private header files. An alternative to the wrapper would have been the version of std::equal that takes four iterators. However, that is a C++14 library feature, while this version of Qt still needs to compile with a C++98 compiler, and, more importantly, there isn't, and never will be, a corresponding 4-iterator version of std::copy.

| * Hide mixed comparisons with QT_RESTRICTED_CAST_FROM_ASCIIhjk2016-03-231-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | While the implementation of the QByteArray::operatorX(const QString &s2) for X \in { ==, !=, <, <=, >, >=} was already inavailable when QT_RESTRICTED_CAST_FROM_ASCII was defined, the declaration was still visible, leading effectively to a linking error. This change hides the declaration, too, creating a compiler error as intended, and as present with the QString::operatorX(const QByteArray &s2) functions.

| * WinRT: Fix QTimeZone transitions by switching backendMaurice Kalinowski2016-03-163-5/+105
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously WinRT was using the UTC backend which fails on all platforms for some QDateTime autotests related to timezone items. Hence switch to the Windows implementation for WinRT as well. However, the windows backend does query the registry heavily, which is not supported on WinRT. Instead use the API version provided by the SDK. Long-term we might want to switch to this version on desktop windows as well, as direct registry access would not be required and we could harmonize the codepaths for both platforms.

| * QRect: fix UB (int overflow) in center()Marc Mutz2016-03-151-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | QRect::center() should be defined for any QRect(x1,y1,x2,x2), INT_MIN <= x1, x2, y1, y2 <= INT_MAX because the average of two signed integers is always representable as a signed integer. But not when it's calculated as (x1+x2)/2, since that expression overflows when x1 > INT_MAX - x2. Instead of playing games with Hacker's Delight-style expressions, or use Google's patented algorithm, which requires two divisions, take advantage of the fact that int is not intmax_t and perform the calculation in the qint64 domain. The cast back to int is always well- defined since, as mentioned, the result is always representable in an int. Fix a test-case that expected a nonsensical result due to overflow. [ChangeLog][QtCore][QRect] Fixed integer overflow in center(). This fixes the result for some corner-cases like a 1x1 rectangle at (INT_MIN, INT_MIN), for which the previous implementation could return anything (due to invoking undefined behavior), but commonly returned (0, 0).
