* QWaitCondition/win: Enable actually waiting longer than u32::maxMårten Nordheim2023-06-011-21/+31
| | | | | | | | | | | | | This is done, in part, by swapping the dependency between the wait() overloads. Furthermore, since QDeadlineTimer is 64-bit and the Win32 API is 32-bit we have to wait more than once to actually wait until the deadline is reached. The unsigned int overload has no documented concept of waiting 'forever'. Though, internally we turn u32::max into 'forever'.

* Port from qAsConst() to std::as_const()Marc Mutz2022-10-111-2/+2
| | | | | | | | | | | | | | | | We've been requiring C++17 since Qt 6.0, and our qAsConst use finally starts to bother us (QTBUG-99313), so time to port away from it now. Since qAsConst has exactly the same semantics as std::as_const (down to rvalue treatment, constexpr'ness and noexcept'ness), there's really nothing more to it than a global search-and-replace, with manual unstaging of the actual definition and documentation in dist/, src/corelib/doc/ and src/corelib/global/.

* Optimized implementation of QReadWriteLockOlivier Goffart2016-03-111-4/+6
| | | | | | | | | | | | | | | | | | | | | | QReadWriteLock is supposed to be a better alternative to QMutex when there are only a few writers but potentially lots of reads. However, in practice the previous implementation was much slower, unless you really do a lot of work with the lock for read and you have lots of contention. Indeed, the previous implementation was locking a QMutex both for lock, and unlock (making it already at least twice as slow as QMutex). This new implementation brings QReadWriteLock back to the same level as QMutex: - No memory allocations in the uncontended case (almost no overhead allowing to create many of them in classes) - Lock-free if there is no contention Should support up to 2^31 concurrent readers on 64 bit platforms, and 2^28 on 32 bit platforms Change-Id: Ifa2fc999075cbb971088f4ee8e6fde78ce262da3 Reviewed-by: Edward Welbourne <edward.welbourne@theqtcompany.com> Reviewed-by: Sean Harmer <sean.harmer@kdab.com> Reviewed-by: Robin Burchell <robin.burchell@viroteck.net>

* Use "Ex"-versions of WaitForSingle/MultipleObject(s) where possibleOliver Wolff2015-06-161-3/+3
| | | | | | | | | | | | | | Not only should using the "Ex"-versions be the rule and not the exception on Windows, but it's only the only way to share as much code as possible between Desktop Windows and WinRT (which is pushed by Microsoft a lot). The current rule of Desktop and WinCE vs WinRT does not make a lot of sense any longer, as WinCE is getting less and less important. By moving these #ifdefs in favor of WinRT, WinCe code might be removed easier in the future.
