* Set CONFIG += benchmark in corelib's various benchmarksEdward Welbourne2020-04-021-7/+4
| | | | | | | | | | | | | | | This leads to "make benchmark" actually running the benchmark, which would be nice, I think. Purged various CONFIG += release or -= debug lines from the same configurations; those surely only configure how the test code is compiled, which is more or less pointless; it's the code under test whose debug/release state matters, and I don't suppose that's affected by the build config of the test code. In the process, reduce diversity of the ordering of lines within these *.pro files and purge some dangling space.

* Optimize QTimer::singleShot(0, ...) when taking PMF or Functor callableMilian Wolff2019-04-061-3/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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;
