Giuseppe D'Angelo 84fba93ebb QThread::create(): request interruption and join on destruction
If one destroys a running QThread, so far the behavior has been to crash
(à la std::thread) -- assuming the thread hasn't already signalled that
it has finished. This behavior is hostile to solutions such as using
QThread::create(), which always require a wait() before destroying the
thread object.

We can use the opportunity to change the behavior without breaking any
valid code. Instead of crashing, inside QThread's destructor we can ask
the new thread to quit, and then join it (à la std::jthread). This
simplifies the implementation of long-living runnables and the code that
manages them.

Deploying this solution for the whole QThread class may not be entirely
painless. While no correct code would work differently with the proposed
changes, incorrect code that deletes a running thread would no longer
crash "loudly" -- instead, it might deadlock "quietly", have memory
corruptions, etc.

Hence I'm limiting this approach to only the threads created by
QThread::create(), at least for the time being. This also side-steps
perhaps the biggest problem of generalizing the approach, which is that
placing such interrupt+join logic into~QThread's destructor would cause
it to be run _after_ a QThread subclass' own destructor has run,
destroying the subclass' data members too early. This might create
an antipattern if one chooses to subclass QThread. With create(), a
subclass in question exists, and it indeed has NSDMs, but it's entirely
under our control (in fact, I'm placing the logic just in its dtor).

[ChangeLog][QtCore][QThread] Destroying a QThread object created by
QThread::create() while the thread that it manages is still running will
now automatically ask that thread to quit, and will wait until the
thread has finished. Before, this resulted in a program crash. See the
documentation of QThread::~QThread() for more details.

Sona Kurazyan 3be72253a6 Fix QFuture continuations/handlers to work with move-only callables
std::function, which is used to store the type-erased continuation
lambdas, requires the passed callable to be copy-constructible. This
makes impossible to use move-only callables with continuations/handlers.
In particular, it makes impossible passing lambdas that are capturing
move-only objects. The workaround is to store the continuation lambda
inside a wrapper for the callable, which stores the move-only lambda in
a QSharedPtr and can be stored in std::function, since it's copyable.

[ChangeLog][QtCore][Important Behavior Changes] The chain of

the cancellation would be ignored. Now the part of the chain that wasn't
started at the moment of cancellation will be canceled.

Marc Mutz 3a72496b5c tests: fix some -Wvolatile
C++20 deprecated compound volatile statements such as pre- and
post-increments, to stress that they're not atomic. So instead of

    volatile i;

you're now supposed to write

    volatile i;

    int j = i; // volatile load
    ++j;
    i = j; // volatile store

which matches more closely what hardware does.

Instead of fixing every use of volatile pre- or post-increment in this
fashion individually, and realising that probably a few more Qt
modules will have the same kind of code patterns in them, write
QtPrivate functions to do the job centrally.

which stores a pointer to the results list and their size. If the size

In case of trying to report results via an empty list, the size is 0, so
result store treats it as a single result.

list isn't empty. Note that empty lists are allowed in some cases for
the filter mode, because ResultStoreBase::addResults() knows how to

- If maximum is smaller than minimum, minimum becomes the only legal

- If the current progress value falls outside the new range, the
progress value is set to be minimum.
- If both progressMinimum() and progressMaximum() return 0, the

These classes should not inherit from each other
anymore in Qt 6. The reason is that this makes
the 95% case of using a non-recursive mutex
much slower than it has to be.

This way, QMutex can now inline the fast path
and be pretty much as fast as QBasicMutex is
in Qt 5. They actually use the same code paths
now. The main difference is that QMutex allows
calling tryLock() with a timeout, which that
is not allowed for QBasicMutex.

Alexandru Croitor 92ee9bd6b8 CMake: Properly handle CONFIG += thread aka Threads::Threads
mkspecs/features/qt.prf adds a dependency on the system threading
library if the Qt Core thread feature is enabled. Because qt.prf is
loaded by any public or internal Qt project, it's essentially a public
dependency for any Qt consumer.

To mimic that in CMake, we check if the thread feature is enabled, and
and set the Threads::Threads library as a dependency of Qt6::Platform,
which is a public target used by all Qt modules and plugins and Qt
consumers.

We also need to create a Qt6Dependencies.cmake file so we
find_package(Threads) every time find_package(Qt6) is called.

For the .prl files to be usable, we have to filter out some
CMake implementation specific directory separator tokens
'CMAKE_DIRECTORY_ID_SEP' aka '::@', which are added because we call
target_link_libraries() with a target created in a different scope
(I think).

As a result of this change, we shouldn't have to hardcode
Threads::Threads in other projects, because it's now a global public
dependency.

QFuture acts as a primary controller of QPromise via action

Sona Kurazyan d7d6a1fe32 Don't queue events in QFutureWatcher when pause is requested
When QFutureWatcher (or QFutureInterface) is paused, it doesn't
mean that it will take effect immediately: the pending tasks may
still be in progress and keep reporting results. At the moment
QFutureWatcher will queue those events and report only with the
next resume. This behavior is wrong, QFutureWatcher should not
decide when to report events, the sender should decide when is the
right time. There's no benefit in reporting already happened events
with delay. Because of this, even the pause event itself was being
reported after resume.

Fixed the behavior by removing the logic of queueing events when
the state is set to "paused". It seems unlikely that the users of
QFutureWatcher rely on reporting events with delay.

[ChangeLog][Important Behavior Changes][QtCore] QFutureWatcher will not
immediately stop delivering progress and result ready signals when the
future is paused. At the moment of pausing there may be still computations
that are in progress and cannot be stopped. Signals for such computations
will be still delivered after pause, instead of being postponed and
reported only after next resume.

Timur Pocheptsov 44ceb56455 QFuture - add ability to move results from QFuture
QFuture's original design pre-dates C++11 and its
introduction of move semantics. QFuture is documented
as requiring copy-constructible classes and uses copy
operations for results (which in Qt's universe in general
is relatively cheap, due to the use of COW/data sharing).
QFuture::result(), QFuture::results(), QFuture::resultAt()
return copies. Now that the year is 2020, it makes some
sense to add support for move semantics and, in particular,
move-only types, like std::unique_ptr (that cannot be
obtained from QFuture using result etc.). Taking a result
or results from a QFuture renders it invalid.  This patch
adds QFuture<T>::takeResults(), takeResult() and isValid().
'Taking' functions are 'enabled_if' for non-void types only
to improve the compiler's diagnostic (which would otherwise
spit some semi-articulate diagnostic).
As a bonus a bug was found in the pre-existing code (after
initially copy and pasted into the new function) - the one
where we incorrectly report ready results in (rather obscure)
filter mode.

Sona Kurazyan dfaca09e85 Add support for attaching continuations to QFuture
Added QFuture::then() methods to allow chaining multiple asynchronous
computations.

Continuations can use the following execution policies:

* QtFuture::Launch::Sync - the continuation will be launched in the same
thread in which the parent has been executing.

* QtFuture::Launch::Async - the continuation will be launched in a new
thread.

* QtFuture::Launch::Inherit - the continuation will inherit the launch
policy of the parent, or its thread pool (if it was using a custom one).

* Additionally then() also accepts a custom QThreadPool* instance.

Note, that if the parent future gets canceled, its continuation(s) will
be also canceled.

If the parent throws an exception, it will be propagated to the
continuation's future, unless it is caught inside the continuation
(if it has a QFuture arg).

Some example usages:

 QFuture<int> future = ...;
 future.then([](int res1){ ... }).then([](int res2){ ... })...

 QFuture<int> future = ...;
 future.then([](QFuture<int> fut1){ /* do something with fut1 */ })...

In the examples above all continuations will run in the same thread as
future.

 QFuture<int> future = ...;
 future.then(QtFuture::Launch::Async, [](int res1){ ... })
       .then([](int res2){ ... })..

In this example the continuations will run in a new thread (but on the
same one).

 QThreadPool pool;
 QFuture<int> future = ...;
 future.then(&pool, [](int res1){ ... })
       .then([](int res2){ ... })..

In this example the continuations will run in the given thread pool.

[ChangeLog][QtCore] Added support for attaching continuations to QFuture.

The macro is not documented, so not part of the public Qt API. It is
made obsolete by the alignof keyword in C++11.

Remove the usage of the macro across qtbase, in particular the
workarounds for compilers that didn't support alignof, and that will
not be supported in Qt 6.

The macro definition is left in place, no need to break existing
code.

Marc Mutz 95310aac6d Short live QRecursiveMutex!
Move the recursive mutex use case out of QMutex into a separate class,
unsurprisingly called QRecursiveMutex. As an immediate benefit, 90% of
the QMutex users now enjoy a constexpr QMutex ctor.

This change prepares for a real split in Qt 6, so that both use-cases
are no longer bundled up in one class.

[ChangeLog][QtCore][QMutex] Added QRecursiveMutex as a replacement of
QMutex(QMutex::Recursive).

Giuseppe D'Angelo 34fe9232db Port from QAtomic::load() to loadRelaxed()
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.

Oliver Wolff 63f78e41dc tst_qthreadstorage: Fix execution for WinRT
Not putting executables into debug/release subdirectories leads to the
WinRT AppxManifest being overwritten by the wrong configuration. When Qt
is configured with -release for example, it was possible that the debug
manifest (Manifest files are always created next to the target) is
written last and thus contains debug VCLibs as a dependency.

Additionally the test was changed in that way, that the resulting file
system structure (having helper and test application in a "top level"
debug and release folder) is the same structure as in tst_qobject.
