* Port from QAtomic::load() to loadRelaxed()Giuseppe D'Angelo2019-06-201-5/+5
| | | | | | | | | | | | | | | Semi-automated, just needed ~20 manual fixes: $ find \( -iname \*.cpp -or -iname \*.h \) -exec perl -pe 's/(\.|->)load\(\)/$1loadRelaxed\(\)/g' -i \{\} + $ find \( -iname \*.cpp -or -iname \*.h \) -exec perl -pe 's/(\.|->)store\(/$1storeRelaxed\(/g' -i \{\} + It can be easily improved (e.g. for store check that there are no commas after the opening parens). The most common offender is QLibrary::load, and some code using std::atomic directly. Change-Id: I07c38a3c8ed32c924ef4999e85c7e45cf48f0f6c Reviewed-by: Marc Mutz <marc.mutz@kdab.com>

* Optimize QSharedPointer::getAndRef with the three-operand testAndSetThiago Macieira2018-11-281-4/+7
| | | | | | | | | | | | | | | | | | | | Originally QAtomicPointer didn't have the three-operand version, resulting in code like: if (!atomic.testAndSetXxx(expected, newvalue)) expected = atomic.load(); The three-operand version gives us the current value of the atomic in case the test failed and it's free in all architectures, unlike the extra load. I have to use testAndSetOrdered here because I need the failing load to use the Acquire memory order, even though that has an extra Acquire for the successful case we don't need. QAtomicPointer does not have testAndSetReleaseAcquire.

| * Fix deleting of QSharedPointer internals in case QPointer loses the raceThiago Macieira2018-10-291-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | QPointer uses QWeakPointer / QSharedPointer internals in QObject and has the code to make sure two threads won't stomp on each other if both try to create a QPointer for the same QObject at the same time. The threading code was fine, but had a mistake in the clean up code for the loser thread: the QtSharedPointer::ExternalRefCountData destructor has a Q_ASSERT for the state of the reference counts. So we need to set the state correctly before calling the destructor. But we don't want to do it in case the Q_ASSERT compiled to nothing. So we use a hack that violates the Second Rule of Q_ASSERTs: don't do something with side-effects. This way, we can insert code that will only be compiled if Q_ASSERTs do something, without having to duplicate the preprocessor conditions from qglobal.h.
