* Optimize QTimer::singleShot(0, ...) when taking PMF or Functor callableMilian Wolff2019-04-062-0/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | QTimer::singleShot is optimized for zero timeouts when using the API taking a string method name. This optimization was not used for the API taking a PMF or functor. This patch adds it, making the various API calls behave similarly from a performance point of view. The approach taken here requires a QObject context object. If none is available, e.g. a nullptr was passed explicitly, or the QTimer::singleShot(O, Functor) API was used, the optimization could not easily be applied. This is not only bad from a performance POV, but also poses as a potential source for heisenbugs: Using the different API versions of QTimer::singleShot would use different code paths internally, which then would not ensure the expected slot call order. This problem actually existed already when mixing the string-based slot syntax with PMF/functors in the QTimer::singleShot API. This patch overcomes this hurdle and fixes all of the above: When we encounter a 0ms single shot timer, and no QObject context object is available, we fall back to the main thread, or create a temporary QObject for any other thread. The updated and extended benchmark shows that this is still a significant performance improvement over using a timer: ********* Start testing of qtimer_vs_qmetaobject ********* Config: Using QtTest library 5.14.0, Qt 5.14.0 (x86_64-little_endian-lp64 shared (dynamic) release build;

This means that we don't need to lock the senders mutex in activate anymore, as long as the reference counting on the ConnectionData is atomic and we are in the senders thread. This implies that we now need to lock the receivers mutex in queued_activate() abd blocking queued activation to ensure it hasn't been deleted while we are emitting. In addition, some precautions need to be taken to not read from the receiver without holding the lock, as it could get deleted while we're activating (if it's in a different thread). To make that possible store the receivers thread id in the connection data. Use atomic pointers for all variables that can get modified with the signalSlotLock() held and that are being read without the lock being held. This gives us a very nice additional speed improvement for signal emissions. without change with change string based connect: 3287 2436 pointer based connect: 3941 3265 not connected: 403 400 disconnected: 460 489 5 slots connected: 9112 4515 Change-Id: Ib7324bb74c389dcc3b6581a03c31469a6e589fc2 Reviewed-by: Olivier Goffart (Woboq GmbH) <ogoffart@woboq.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If you enter a nested event loop, cause a deleteLater(), exit that event loop, then enter a new one, the nesting count will be the same so those are legitimate targets for deletion.

Additionally, it can assume the variable did not change from there to 712 // still nothing - wait for message or signalled objects 713 canWait = (!retVal 714 && !d->interrupt 715 && (flags & QEventLoop::WaitForMoreEvents)); Which causes canWait to be true, despite having been interrupted by another thread. Changing to an atomic does not force the reloading of the variable (strictly speaking, would need volatile, but all atomic implementations do reload now), but it solves the problem of data race, which was UB. The equivalent variable in the Unix event dispatcher is atomic (commit 49d7e71f77f899c05e4b5187e8834dfcbddf4505 from 2013). I've reordered the bool members so they're all together and reduce the amount of padding in this class.
