* Q(Static)ByteArrayMatcher: manage indexIn() overloadsMarc Mutz2022-01-234-19/+56
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Unlike QString and QStringView, QByteArrayView and QByteArray don't overload well. Solve the overload issue the usual way: by making the QByteArray one a Q_WEAK_OVERLOAD. This is trivial for QStaticByteArrayMatcher, which isn't exported, but require QT_REMOVED_SINCE magic for QByteArrayMatcher, which is. The additional const char* overload has shielded us from the worst fall-out so far, it seems, but it makes for a truly horrible overload set: matcher.indexIn(str, 3); Q: Is the 3 here the length of the haystack or the value of the from parameter? A: It depends on decltype(str)! If the (const char*, qsizetype, qsizetype=0) overload is the better match, then 3 limits the haystack's length. If, otoh, the (QByteArray(View), qsizetype) overload is the better match, then it's the value of the from parameter. As if this wasn't bad enough, QByteArray implcitly converts to const char* by default! A follow-up patch will therefore deprecate the (ptr, size) overloads, so we de-inline the QByteArrayView ones to avoid having to touch the implementation once more. Found during 6.3 API review.

| | | | | | | | | | | | | | | After QFuture continuations became non-copyable (see earlier commits), we have to always use ContinuationWrapper to save the continuations inside std::function, since it requires the callable to be copyable. Optimize the wrapper, by storing the callable directly (instead of using a ref-counted QSharedPointer) and introducing a fake copy-constructor that makes sure that it's never called.

| | | | | | | | | | | | | | | | | Continuations were using QFutureInterface to create and return the associated future to the user. Attaching a continuation to the returned future could cause memory leaks (described in an earlier commit).

* Fix memory leaks when capturing a QFuture in its continuationSona Kurazyan2022-01-214-3/+86
| | | | | | | | | | | | | | | | | | | | | | Capturing a QFuture in the continuations attached to it results in memory leaks. QFuture's ref-counted data can only be deleted when the last copy referencing the data gets deleted. The saved continuation that keeps a copy of the future (as in case of the lambda capture) will prevent the data from being deleted. So we need to manually clean the continuation after it is run. But this doesn't solve the problem if the continuation isn't run. In that case, clean the continuation in the destructor of the associated QPromise. To avoid similar leaks, internally we should always create futures via QPromise, instead of the ref-counted QFutureInterface, so that the continuation is always cleaned in the destructor. Currently QFuture continuations and QtFuture::when* methods use QFutureInterface directly, which will be fixed by the follow-up commits.

* qsimd_p.h: add a hack to allow AVX to work with MinGWThiago Macieira2022-01-202-3/+23
| | | | | | | | | | | | | | | | | | | GCC is unable to emit the SEH metadata about the stack aligning that is required to execute AVX aligned instructions (VMOVDQA, VMOVAPS, etc.), so it just doesn't align the stack. That causes crashes on a 50/50 chance every time the compiler attempts to address a stack-aligned variable. In a debug-mode build, because it always loads & saves everything on the stack, the chance of a crash happening is a near certainty. So we hack around it by going behind the compiler's back and instructing the assembler to emit the unaligned counterparts of the instructions every time the compiler wished to emit the aligned one. There's no performance penalty: if the variable is actually aligned, the unaligned instruction executes in the exact same time.
