* QtQml: Fix clashes with windows.h definesFriedemann Kleint2023-02-221-2/+2

* Profiler: Add move operations to FunctionCallUlf Hermann2022-11-141-0/+1
| | | | | | | | | | | This requires us to check the pointer on destruction, but should make list operations faster, due to the refcount becoming unnecessary. It also fixes some compiler warnings.

* Port from qAsConst() to std::as_const()Marc Mutz2022-10-071-1/+1
| | | | | | | | | | | | | | We've been requiring C++17 since Qt 6.0, and our qAsConst use finally starts to bother us (QTBUG-99313), so time to port away from it now. Since qAsConst has exactly the same semantics as std::as_const (down to rvalue treatment, constexpr'ness and noexcept'ness), there's really nothing more to it than a global search-and-replace.

| | | | | | | | | | | | Saving the name/file/line/column over and over for each function call is wasteful. We can instead key them by the pointer to the JS Function object. Also, make sure we don't accidentally detach the data when sending messages.

* std::sort JS profiling data instead of insert-sorting itUlf Hermann2015-08-241-12/+17
| | | | | | | | | | | | | The original FunctionCall struct is much smaller than the resulting FunctionCallProperties, and thus not as expensive to copy. Repeatedly calling upper_bound on a QVector is not such a great idea, either. Since the usage of QVector instead of QList for the results is new in Qt 5.6, the insert-sorting got slower, making this change a fix for a performance regression.

* Periodically flush profiling data to client.Ulf Hermann2015-08-041-3/+2
| | | | | | | | | | | | | | | | | | | | This reduces memory usage as the data can be deleted once it is sent. It also reduces the time it takes to transmit the data when profiling is stopped. It does incur a runtime cost as the sending now takes place while the application is running. The decision to periodically flush or not is left to the client, who can specify a flush interval when starting profiling. Usage of the flushing feature also relaxes the guarantees regarding the sorting of events before they are sent. Events with higher timestamps are now allowed to arrive before events with lower timestamps. Any clients implementing the flushing need to take this into account. This will eventually allow us to do away with the server-side ordering altogether.

* Select specific features to be recorded when profiling QMLUlf Hermann2014-09-111-18/+20
| | | | | | | | | | | | Some features, like the memory profiler, create huge amounts of data. Often enough, we're not actually interested in all the data available from the profiler and collecting it all can lead to excessive memory consumption. This change enables us to optionally turn various aspects of QML profiling off.
