* Add QScriptDeclarativeClassAaron Kennedy2009-11-101-1/+1
| | | | | | | | | QScriptDeclarativeClass is a private, but exported, class used by the declarativeui module. It is very similar to QScriptClass, but slightly faster and provides a couple of "backdoor" extension mechanisms used by declarative. Reviewed-by: Warwick Allison
* Say hello to QScriptProgram :-)Kent Hansen2009-10-281-0/+5
| | | | | | | | | | | QScriptProgram encapsulates a Qt Script program (AKA a script). It retains the compiled representation of the script, so that repeated evaluation of the same script becomes faster. An overload of QScriptEngine::evaluate() that takes a QScriptProgram has been added. Reviewed-by: Olivier Goffart

* Use the qsreal type instead of double when working with QtScript numbersKent Hansen2009-10-221-1/+1
| | | | | | | | The idea is that qsreal can be typedef'ed to float on platforms where it's appropriate. Since the QScriptValue ctor takes a qsreal, we should not convert it to a double internally. Reviewed-by: Olivier Goffart
* Regression fix. Fix the hasUncaughtException() flag in debugger's event.Jedrzej Nowacki2009-10-191-0/+5
| | | | | | | | | | | The QScriptEngine::hasUncaughtException() flag should be set to true if returning from a JS function was caused by an exception. According to documentation, the flag had to be accessible from the QScriptEngineAgent::functionExit event. New autotest was added. Reviewed-by: Kent Hansen

* QScript: Fix strange bugs and crashes.Olivier Goffart2009-09-281-1/+2
| | | | | | | | | | I was assuming that the default return value register was always set to 0 for native calls. But this is not the case. So we must ensure this.

* Fix compilation with winscwSimon Hausmann2009-09-101-2/+2
| | | | | | | | Winscw gets very confused when the name of an enum value is the same as the name of an entire namespace, JSC in this case. Renaming the enum value to JavaScriptCore fixes this. Rubber-stamped-by: Kent

* handle memory management of QScriptValuePrivate in engine if possibleKent Hansen2009-08-241-0/+4
| | | | | | | | | Avoid calling malloc() and free() so often. The premise is that QScriptValue is usually a short-lived type, and only a few QScriptValues exist at a time, so if we cache privates in the engine, QScriptValues will be much faster to create and destroy. Reviewed-by: Olivier Goffart

* make QScriptEngine::isEvaluating() work for top-level evaluationKent Hansen2009-08-191-0/+1
| | | | | | Since QScriptEngine::evaluate() doesn't create a new stack frame anymore, we need to use a dedicated variable to keep track of whether the engine is currently evaluating or not.

* Lazily construct the QScriptActivationObjectOlivier Goffart2009-08-131-0/+9
| | | | | | | | | | | We can store flags on the ReturnValueRegister entry in the stackframe header (as native function don't use that) Then when requesting an activation object we can lookup the flags to know if we should create it.

* add configure options for (not) building the QtScript moduleKent Hansen2009-08-071-4/+0
| | | | | | | | | | | | | | | | | | -script (default) and -no-script. This means we can get rid of the SCRIPT feature from qfeatures, since it's now handled by the new configure variable. It also allows us to get rid of all the QT_NO_SCRIPT ifdefs from the source files, since qmake isn't going to include those files for compilation when you configure with -no-script. The QtScriptTools module will be disabled if the QtScript module is not built. You'll have to build the old QtScript back-end (will be made available in a separate package), then build the QtScriptTools module yourself. Reviewed-by: Simon Hausmann

* Remove QScriptContextPrivate, QScriptContext is now a JSC::CallFrameOlivier Goffart2009-07-311-1/+2
| | | | | | | | | | | | | | There will not be instances of QScriptContext anymore. Pointer to QScriptContext are just pointer to JSC::CallFrame This simplifies the code as we do not need to manage the memory for the QScriptContext anymore. It is compatible because it is not possible to create QScriptContext. They were all created by QScriptEngine. QScriptContext constructor is private. Aknoweldged-by: Kent

* make QScriptEngine::setGlobalObject() work to some extentKent Hansen2009-07-271-2/+7
| | | | | | | | | | | | | | | | | | | | | | | | | JSC requires that the global object is actually a JSGlobalObject instance, whereas QScriptEngine::setGlobalObject() allows any object to be set as the global object. The way we solve this is by proxying from an internal global object to the custom (user-set) object. We need to take care that the internal global object is never actually exposed through our API; a brilliantly named helper function, toUsableValue(), makes that happen. Evaluating "var a = 10" with a custom global object doesn't work yet; the variable always ends up in the internal Global Object. For variable assignments, JSC appears to bypass the normal JSObject::put() and instead use JSGlobalObject::copyGlobals{From,To}(), which means I can't intercept and proxy the assignments. This commit enough to get the Context2D example working. There's another bug with iteration of the built-in Global Object's properties (non-enumerable properties are always skipped by the JSC C++ API, whereas with QScriptValueIterator they should not be), but that's a totally separate issue.
* don't rely on custom global object to get GC callbackKent Hansen2009-07-271-1/+3
| | | | | | | | | | | Install custom ClientData on JSGlobalData instance instead. Also some cleanups to avoid globalObject et al being accessed directly. Killed the proxying scheme employed in setGlobalObject() since it didn't work; if you stored the original Global Object and replaced it with another object, then added properties to the new object, they would show up in the old object, too (because the old object would always proxy to whatever the current Global Object was).
