* QmlProfiler: Reduce memory usage for file names and URLsUlf Hermann2016-05-021-66/+145
| | | | | | | | | | | | | | | | | | | | | 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.

* QmlProfiler: Pass detailType directly, rather than as a bit fieldUlf Hermann2016-04-271-13/+13
| | | | | | | | | | There can only be one detail type for compressed set of messages. This is unlikely to change anytime soon. Also, be more careful about not detaching the data when sending the messages.

* Fix profiling of QML/JS compilationUlf Hermann2015-08-241-5/+6
| | | | | | | | | | | | | | | | | | | The compilation of .js resources was missed and the compile times were underestimated because the dependency resolution and error checking wasn't factored in. In particular we only profiled the done() step for QQmlTypeData. However, JavaScript compilation also occurs in the dataReceived() step of QQmlScriptBlob and QQmlTypeData will already parse the program into an AST at that step. Compile steps can be nested now, but considering the fact that significant time may be spent before and after compiling dependencies for a parent module, this seems to be the best way to model them. Furthermore, in order to not needlessly convert QUrl to QString at runtime, the compilation profiler saves the files now as QUrl.

* Periodically flush profiling data to client.Ulf Hermann2015-08-041-1/+1
| | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | 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.

| | | | | | | | | | | | | | 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.
