* Replace discouraged Q_MOVABLE_TYPE by Q_RELOCATABLE_TYPEAndreas Buhr2020-12-043-5/+5
| | | | | | | | | | | | | | | Q_MOVABLE_TYPE was conceived before C++ had move semantics. Now, with move semantics, its name is misleading. Q_RELOCATABLE_TYPE was introduced as a synonym to Q_MOVABLE_TYPE. Usage of Q_MOVABLE_TYPE is discouraged now. This patch replaces all usages of Q_MOVABLE_TYPE by Q_RELOCATABLE_TYPE in QtBase. As the two are synonymous, this patch should have no impact on users.

* Fix QVariant/QMetaType::compare APIsGiuseppe D'Angelo2020-11-253-0/+291
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | std::optional<int> is the wrong datatype to use for compare. First and foremost, it can't be used in the idiomatic form of auto r = a.compare(b); if (r < 0) ~~~ // a is less than b if (r > 0) ~~~ // a is greater than b which we *already* feature in Qt (QString, QByteArray). Also, std::optional<int> (explicitly) converts to bool, which is a trap, because the result of the comparison can be accidentally tested as a bool: if (a.compare(b)) ~~~ // oops! does NOT mean a<b Not to mention extending this to algorithms: auto lessThan = [](QVariant a, QVariant b) { return a.compare(b); }; // oops! std::ranges::sort(vectorOfVariants, lessThan); which thankfully doesn't compile as is -- std::optional has an *explicit* operator bool, and the Compare concept requires an implicit conversion. However, the error the user is going to face will be "cannot convert to bool because the operator is explicit", which is deceiving because the fix is NOT supposed to be: auto lessThan = [](QVariant a, QVariant b) { return (bool)a.compare(b); }; // big oops! Instead: backport to Qt the required subset of C++20's <compare> API, and use that. This commits just adds the necessary parts for compare() (i.e. partial ordering), the rest of <compare> (classes, functions, conversions) can be added to 6.1.

* QFileInfo: mark constructors as explicitGiuseppe D'Angelo2020-11-151-2/+2
| | | | | | | | | | | | | | | | | | | | | | | These look like leftovers (API flaws). Construction of QFileInfo from QString (or similar) should be not implicit, as QFileInfo construction is expensive (might hit the file system), and this may have users overlook APIs (for instance build a QFileInfo out of QDirIterator::next(), instead of using ::fileInfo(); using QDir::entryList instead of entryInfoList; etc.). Leave an opt-out mechanism to ease porting. Fix a handful of usages around qtbase, with at least a couple of them likely to be actual "sloppy" code. [ChangeLog][Potentially Source-Incompatible Changes][QFileInfo] Most QFileInfo constructors are now explicit. The QT_IMPLICIT_QFILEINFO_CONSTRUCTION macro is provided to keep old code working.

* QRandomGenerator: add 64-bit bounded() versionsThiago Macieira2020-10-202-2/+152
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Unlike the 32-bit version, we can't go to a bigger integer type to do the multiplication with. So instead accept looping. Both libstdc++ and libc++ implement std::uniform_int_distribution this way anyway, but in a far more complex way. There is no looping if the "highest" is a power of two. The worst-case scenario is when "highest" is one past a power of two (like 65). In that case, we'll loop until the number is in range. Since all bits have equal probability of being zero or one, there's a 50-50 chance that the most significant useful bit will be set[*], in which case we'll need to loop and we again get the same probability. So on average, we only need two iterations to get an acceptable result. [*] There's also a possibility that the other bits are such that the number is still in range. For 65, we'd need the other 5 bits to be zero (64 is a valid result), but the probability of that is only 1/2^5 = 3.125%. The bigger "highest" is, the closer we get to zero, so approximate by saying that never happens and instead calculate that the most significant useful bit is the controlling one. [ChangeLog][QtCore][QRandomGenerator] Added 64-bit versions of the bounded() functions. They are useful in conjunction with Qt 6's 64-bit container sizes, so code that used to call bounded(list.size()) in Qt 5 will continue to compile and work in Qt 6.

* Long live Q_IMPLICIT!Giuseppe D'Angelo2020-10-142-2/+8
| | | | | | | | | | | | | C++20 will give us explicit(bool). While we can't use it just yet in its full potential, we can introduce a macro to start marking our implicit conversions (aka `explicit(false)`), removing the need for /* implicit */-like comments. Port a few usages to it. Change-Id: I336d5e4c8d51d8329627900d1059e59062c5cafd Reviewed-by: Fabian Kosmale <fabian.kosmale@qt.io> Reviewed-by: Lars Knoll <lars.knoll@qt.io>
* Drop qt_is_permutationGiuseppe D'Angelo2020-10-141-23/+0
| | | | | | | | | | It was a workaround until we could depend on C++14's std::is_permutation overload with 4 args. We now can, and the code using it is gone anyhow, so drop it.

* MinGW: Fix static build using PCHCristian Adam2020-10-091-1/+1
| | | | | | | | | | | | | | | | | | The value of NTDDI_VERSION is computed from _WIN32_WINNT. It makes sense to keep these two in sync. The value used to create the PCHs for _WIN32_WINNT is 0x601, and qwindowspointerhandler.cpp requires for MinGW 0x603. Since the precompile header value cannot be undefined while compiling the source file, it's better not to use the PCH for this particular source file. These problems surface in a static build, in a regular build for some reason the PCH for plugins is not used.
