* Replace usages of Q_CLANG_QDOC with Q_QDOCLuca Di Sera2022-10-211-1/+1
| | | | | | | | | | | | | | | | | | | | | | | To allow the user to customize the C++ code that QDoc sees, so as to be able to work-around some limitations on QDoc itself, QDoc defines two symbols: Q_QDOC and Q_CLANG_QDOC, both of which are "true" during an entire execution of QDoc. At a certain point in time, QDoc allowed the user the choice between a custom C++ parser and a Clang based one. The Q_QDOC symbol would always be defined while the Q_CLANG_QDOC symbol would be defined only when the Clang based parser was chosen. In more recent times, QDoc always uses a Clang based parser, such that both Q_CLANG_QDOC and Q_QDOC are always defined, making them equivalent. To avoid using different symbols, and the possible confusion and fragmentation that derives from it, all usages of Q_CLANG_QDOC are now replaced by the equivalent usages of Q_QDOC.

* QtCore: replace qSwap with std::swap/member-swap where possibleMarc Mutz2022-01-201-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | qSwap() is a monster that looks for ADL overloads of swap() and also detects the noexcept of the wrapped swap() function, so it should only be used when the argument type is unknown. In the vast majority of cases, the type is known to be efficiently std::swap()able or to have a member-swap. Call either of these. For the common case of pointer types, circumvent the expensive trait checks on std::swap() by providing a hand-rolled qt_ptr_swap() template, the advantage being that it can be unconditionally noexcept, removing all type traits instantiations. Don't document it, otherwise we'd be unable to pick it to 6.2. Effects on Clang -ftime-trace of a PCH'ed libQt6Gui.so build: before: **** Template sets that took longest to instantiate: [...] 27766 ms: qSwap<$> (9073 times, avg 3 ms) [...] 2806 ms: std::swap<$> (1229 times, avg 2 ms) (30572ms) after: **** Template sets that took longest to instantiate: [...] 5047 ms: qSwap<$> (641 times, avg 7 ms) [...] 3371 ms: std::swap<$> (1376 times, avg 2 ms) [qt_ptr_swap<$> does not appear in the top 400, so < 905ms] (< 9323ms) As a drive-by, remove superfluous inline keywords and template ornaments.

* QFuture: put the result store and the exception store in a unionSona Kurazyan2021-06-121-0/+2
| | | | | | | | | | | | | | QFuture doesn't need both at the same time, calling QFuture::result(s) either returns a result or throws an exception. Store result and exception stores in a union, to reduce the memory. Also added a note for making the ResultStoreBase destructor non-virtual in Qt 7.

* Store std::exception_ptr in QUnhandledExceptionSona Kurazyan2020-10-261-2/+18
| | | | | | | | | | | | | | | | For historical reasons Qt Concurrent reports QUnhandledException in case if an exception that is not derived from QException is thrown from a worker thread. Changing this behavior may not be a good idea, since the existing user code may rely on it. Changed QUnhandledException to wrap the std::exception_ptr to the actual exception, so that the users can obtain the information about the thrown exception if needed. [ChangeLog][QtCore][QUnhandledException] Improved QUnhandledException to store the std::exception_ptr to the actual exception thrown from a QtCocnurrent worker thread.

| | | | | | | | | | | | | | | | | | | De-duplicates vtables and enables RTTI on this hierarchy. This is esp. important for exception classes, as RTTI is used to select the catch clause to handle the exception in-flight. The issue is made a bit complicated by the fact that the exception specification changed from C++98 to 11 and that C++98 clients require the empty throw() specification while we don't want to introduce warnings for C++11 users. Let's hope no compiler includes throw specs into the mangled names.
