* QmlProfiler: Reduce memory usage for file names and URLsUlf Hermann2016-05-021-2/+14
| | | | | | | | | | | | | | | | | | | | | As the various file names are actually not kept as QStrings in the respective objects being profiled, our saving them as QStrings in each and every profiling event is not implicitly shared and causes a huge memory overhead. Avoid that by saving each location only once, indexed by a disguised pointer to the object it refers to. Normally, objects could disappear during the profiling session, and new objects could be allocated in their place, which would mess up our indexing system. We prevent that by referencing the objects when we index them, thus preventing them from getting auto-destructed. Mind that those are not JavaScript objects but rather functions, bindings, components and the like. So, this will only cause a memory leak if you're compiling and dropping QML components over and over.

* Periodically flush profiling data to client.Ulf Hermann2015-08-041-7/+6
| | | | | | | | | | | | | | | | | | | | 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 Hermann2014-09-111-7/+7
| | | | | | | | | | | | 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.

* Use RAII for VME profilerUlf Hermann2014-04-031-55/+0
| | | | | | | | | | | | | | Now that object creation is done in nested function calls we can use an RAII-type profiler to trace it. This makes the profiling much simpler and more robust. Also, the stack of profiling data in the VME profiler has to match the stack of completion callbacks in the VME, so the push and pop operations are synchronized now.
