* Clean up data format for V4 debug connectionUlf Hermann2015-08-191-12/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | This changes the type announced for functions to the actual JavaScript type "function". The type for null is also wrong: it should be "object". However, older QtCreators cannot distinguish between null and {} if null gets the correct type, unless you explicitly compare x === null in an expression evaluator. For this reason the fake "null" type is kept for now. Also, the value field of undefined is now set as QJsonValue::Undefined which causes it to be omitted when sent over the wire. This is the logical thing to do. In addition we add type and value fields for all data members mentioned in a response, not only the ones specifically asked for. The value field is the actual value for any primitives (including strings), or the number of properties for composite types: objects, arrays, functions. In turn, the "ref" members are omitted for primitive types, so that we don't have to hold references to them in the debug service anymore. Even old QtCreators can deal with verbatim data members without "ref".

* Move DataCollector into debugger pluginUlf Hermann2015-08-102-15/+33
| | | | | | | | The data collector and all the jobs it uses to interact with the engine are only used from the debugger plugin. We can as well move them there. Change-Id: Ia48251f08b48c7e1e607b8ae2a3d1de29f80f742 Reviewed-by: Erik Verbruggen <erik.verbruggen@theqtcompany.com>
* Move V4 debugger agent into the debugger pluginUlf Hermann2015-08-101-30/+34
| | | | | | | | | | The debugger is the only thing that actually needs it. Note that for this to work we need to make QV4::Debugging::Debugger a QObject and add some signals. The net effect is still a reduction in binary size of about 1kb. Change-Id: Ibecb8cfa140fc26fc13c8cbefb3d027ebdcd28a4 Reviewed-by: Erik Verbruggen <erik.verbruggen@theqtcompany.com>
* Change data collection for debugging to use QV4::Value.Ulf Hermann2015-08-101-131/+162
| | | | | | | | | | | | | | | | This patch changes the variable collection to store QV4::Value values into a JS array, which is retained by the collector. This prevents any GC issues, and gives a nice mapping from handle (used in the debugging protocol) to JS value. It also allows for easy "shallow" object serialization: any lookup can start with the QV4::Value, and add any values it encounters to the array. Testing is changed to use this collector directly, thereby testing the class that is actually used to generate protocol data.

* Move exceptionValue and globalObject from the Engine onto the JS stackLars Knoll2015-04-241-1/+1
| | | | | | | | | We'll need to move all GC'ed objects currently stored in ExecutionEngine onto the JS stack for easier management in a new garbage collection scheme.
