* QEventDispatcher*: port the Unix dispatchers to V2Thiago Macieira2024-03-131-7/+7
| | | | | | | | | | | They're all ported in one go because all the changes are the same and they all rely on QTimerInfoList. The changes are: - use Qt::TimerId to uniquely identify timer IDs - use Duration (nanoseconds) to specify the timer interval - rename registeredTimers() to timersForObject(), which is const Change-Id: I83dda2d36c904517b3c0fffd17b52958767d8a68 Reviewed-by: Ahmad Samir <a.samirh78@gmail.com>
* QEventDispatcherUNIX: remove the fallback to pipes on eventfd systemsThiago Macieira2023-07-241-4/+4
| | | | | | | | | | | | | | | | | Linux has had it since 2.6.23, which is positively ancient from our perspective. No one runs Qt on systems anywhere near that old (I'd be amazed if anyone managed on CentOS / RHEL 7, which carries Linux 3.10). And we don't deal with ENOSYS on FreeBSD either. The removal is accomplished by dead code elimination: it's still compiled on Linux and FreeBSD. Drive-by - use NSDMI in QThreadPipe - remove EINTR_LOOP for eventfd_write(3): it can't be interrupted Change-Id: I63b988479db546dabffcfffd1766e2c7acc6da46 Reviewed-by: Fabian Kosmale <fabian.kosmale@qt.io>

| | | | | | | | | | | | | | | | | | | | Minimal fix for the missing wakeup issue, in leu of a new event loop implementation. So far, emscripten_async_run_in_main_runtime_thread_ looks to be our option for scheduling calls on the main thread. This function is available on emsdk 1.38.22 and higher. Requires making from QEventDispatcherUNIX::wakeUp() non-final. The future event dispatcher implementation will not inherit QEventDispatcherUNIX, so this is a temporary change.

| | | | | | | | | | | | | | | | | | | The main event loop will be paused when an application is suspended, this is also the normal behavior of any Android application. When an application is suspended on Android all its Gl surfaces are destroyed and can't be used to render anymore. So, we need to pause the main event loop in order to pause all the timers which might trigger drawings. The event loop is resumed immediately after the application is foreground.

|/ | | | | | | | | | | | | | eventfd(7) uses less resources than a pipe, as it only needs to store a single 64-bit integer, as opposed to a full buffer. It was introduced first on Linux version 2.6.22 and glibc 2.7. However, both the configure-time test and the runtime usage require the use of EFD_CLOEXEC for thread-safety, so this code will be enabled only for Linux 2.6.27 and up as well as glibc 2.9 and up.

* Add a remainingTime() method to the public interface of the QTimer classLaszlo Papp2012-04-031-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | It is an extension coming from the use case when you, for instance, need to implement a countdown timer in client codes, and manually maintain a dedicated variable for counting down with the help of yet another Timer. There might be other use cases as well. The returned value is meant to be in milliseconds, as the method documentation says, since it is reasonable, and consistent with the rest (ie. the interval accessor). The elapsed time is already being tracked inside the event dispatcher, thus the effort is only exposing that for all platforms supported according to the desired timer identifier, and propagating up to the QTimer public API. It is done by using the QTimerInfoList class in the glib and unix dispatchers, and the WinTimeInfo struct for the windows dispatcher. It might be a good idea to to establish a QWinTimerInfo (qtimerinfo_win{_p.h,cpp}) in the future for resembling the interface for windows with the glib/unix management so that it would be consistent. That would mean abstracting out a base class (~interface) for the timer info classes. Something like that QAbstractTimerInfo. Test: Build test only on (Arch)Linux, Windows and Mac. I have also run the unit tests and they passed as well. Change-Id: Ie37b3aff909313ebc92e511e27d029abb070f110 Reviewed-by: Thiago Macieira <thiago.macieira@intel.com> Reviewed-by: Bradley T.

* Add Qt::TimerType argument to QAbstractEventDispatcher::registerTimer()Bradley T. Hughes2012-01-021-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | ... and deprecate the old registerTimer() functions. The new pure- virtual registerTimer() breaks source-compatibility. Subclasses cannot be instantiated anymore, since the pure virtual function signature has changed. QAbstractEventDispatcher::TimerInfo is no longer a QPair. It is now a struct with timerId, interval, and timerType members. This is a source incompatibility that should only affect subclasses of QAbstractEventDispatcher, which will need to pass 3 arguments to the TimerInfo constructor instead of 2. If the subclass used QPair<int,int> instead of the TimerInfo typedef, the QPair<int,int> declarations will need to be replaced with TimerInfo. Call the new registerTimer() function with the type from QObject::startTimer(). Change all subclasses of QAbstractEventDispatcher to reimplement the new virtual function. The type argument is unused at the momemnt, except to ensure that registeredTimers() returns the type each timer was registered with. Implementations for the various dispatchers will be done in separate commits.
