* don't crash when attempting to access properties of a JS Object that ↵Kent Hansen2009-08-261-24/+23
| | | | | | | | | | | belonged to a deleted script engine When the engine is deleted, the JSValue is invalidated, but the QScriptValue's type will still be QScriptValuePrivate::JSC. Use a new helper function, isObject(), that checks both that the value is of type JSC _and_ that it is valid, before calling JSValue::isObject() (JSValue::isObject() assumes that the value is valid).
* fix performance issue with QScriptValue::propertyFlags()Kent Hansen2009-08-261-28/+37
| | | | | | | Calling QScriptEngine::toStringHandle() is dead slow, so don't call it; use JSC::Identifier directly. This is the same issue as was fixed for setProperty() in commit a8574172dd5e6bc11cf6f69b6fad5a063549e88d.
* fix performance issue with QScriptValue::setProperty()Kent Hansen2009-08-241-75/+81
| | | | | Calling QScriptEngine::toStringHandle() is dead slow, so don't call it; use JSC::Identifier() directly instead.

* handle memory management of QScriptValuePrivate in engine if possibleKent Hansen2009-08-241-15/+31
| | | | | | | | | 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

* store the engine's d-pointer in QScriptValuePrivateKent Hansen2009-08-201-117/+85
| | | | | It's the d-pointer that we most frequently want to access, so store it to avoid having to use QScriptEnginePrivate::get() all over the place.

* Lazily construct the QScriptActivationObjectOlivier Goffart2009-08-131-0/+5
| | | | | | | | | | | 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. This reduce a lot the cost of a native call. Reviewed-by: Kent Hansen

* 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 docs that mention QScriptValue::{scope,setScope}()Kent Hansen2009-08-061-2/+2

* make more tests pass for QScriptValue::setProperty()Kent Hansen2009-07-281-23/+53
| | | | | | JSC doesn't provide a way of un-defining a getter/setter. If deleting e.g. only the setter, we remember the getter, delete the property, then re-establish the getter.
* make QScriptEngine::setGlobalObject() work to some extentKent Hansen2009-07-271-4/+5
| | | | | | | | | | | | | | | | | | | | | | | | | 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 Hansen2009-07-271-2/+2
| | | | | | | | | | | 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).
* Remove the uncaughtException, use the JSC exception insteadBenjamin Poulain2009-07-271-16/+7

* don't try to be so cleverKent Hansen2009-07-151-7/+4
| | | | | | If we implement the ability to change the global object, the global object pointer can change, so we need to keep a reference to the object if it's stored in a QScriptValue.
