* Move QElapsedTimer to src/corelib/kernelThiago Macieira2016-07-021-251/+0
| | | | | | | | | | | | It's really a kernel functionality, as it implements really low-level functionality and it's used by the event dispatcher. It was in tools/ only because QTime is. QDeadlineTimer is also coming to kernel/.

| * QNX: Revert the change to give higher precision timers.Roger Maclean2014-12-241-16/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The previous change (SHA 82c2118c) to provide better than 1ms accuracy for timers on QNX is not safe. According to the docs, ClockCycles is not guaranteed to return consistent information if called from different CPUs. While this can be addressed by locking the thread to a single CPU, you wouldn't want to do that here. On some systems (e.g. BB10) the behavior is extremely bad since ClockCycles only has 32 bits of precision. This results in overflows in the calculations making short timers run very slowly (16ms timers were around 1s). Also ClockCycles wraps in under three minutes causing even more problems. I've talked to the kernel developers and there is currently nothing that will give you better than 1ms accuracy. An individual program could use ClockCycles to calculate more accurate times if they want. It's not clear to me what benefit one would get with increased accuracy. Unless I've missed something, these times are only used to calculate timeouts for calls such as select. These timeouts will themselves have the same resolution as clock_gettime provides so the increased accuracy would appear to be for naught.

* QElapsedTimer: Instead of two ints, store only the clock typeThiago Macieira2012-10-101-46/+82
| | | | | | | | | | | | | | | | | | We don't need two ints if we can do it with one. We need to store only the clock type to be used, which is either CLOCK_MONOTONIC or CLOCK_REALTIME. In addition, we need an invalid value to indicate that the test hasn't been done yet. This also gets rid of an atomic that wasn't QBasicAtomicInt. Disassembly of the compiled code indicates this is the most optimal solution: - one single variable load - one test-and-branch to verify that a test is needed - straight call to clock_gettime afterwards Change-Id: I49788e45b50b6b7fcb7ba4e9332e5352a4428933 Reviewed-by: Olivier Goffart <ogoffart@woboq.com>

| | | | | | | | | | | | | | | There's a comment saying nanosleep's availability is questionable, but the information of what systems don't have that is now lost in time. It's quite likely that they were older, Unix systems we no longer support anyway. nanosleep comes from POSIX.1b-1993, which is merged into POSIX.1-2001, so chances are that it's supported almost everywhere where Qt runs (except for Windows anyway).

* Make QElapsedTimer always store nanoseconds in t2Thiago Macieira2012-08-131-18/+15
| | | | | | | | | | | | | Up until now, the value stored in t2 depended on whether we had found a monotonic clock or not. Fix that by always storing nanoseconds: we avoid extra calculations and accessing a global variable all the time. The impact is contained to the actual getting of the time. And we mitigate by using clock_gettime to get the realtime clock instead of gettimeofday, if that's available.

* Mark QElapsedTimer functions as Q_DECL_NOTHROWThiago Macieira2012-08-091-11/+11
| | | | | | | | | | | | | | | | | | All functions in QElapsedTimer are marked Q_DECL_NOTHROW. This code is often introduced in many places to deal with timeouts and doesn't need exception handlers. In particular, it's used in QMutex locking. In addition, mark QDateTime::currentMSecsSinceEpoch as nothrow, as it can't throw exceptions either and it is needed by the generic QElapsedTimer. Q{Date,Time}::current{Date,Time} operate on local time and run into at least one cancellation point, which we must consider throwing. And returning a QDateTime allocates memory.
