| | | | | | We store the abort-state in the TimeoutChecker, since that's where we'll mostly access it, but the abort result is stored in the QScriptEngine's d-pointer.

* Complete the implementation of QScriptValueIterator with JSCoreBenjamin Poulain2009-08-031-24/+43
| | | | | | | | | | | | | This new implementation of QScriptValueIterator passes all the tests. QScriptValueIterator uses an linked list instead of JSC::PropertyNameArray so the list can be modified by ::remove() and to be able to add internal properties for the strings and arrays. Structure::getPropertyNames() has been modified to not show the property from the prototype. Reviewed-by: Kent Hansen

* QScriptContext::calledAsConstructor also works with non-native functionOlivier Goffart2009-08-031-5/+21
| | | | | | | Use the opcode to see if it was called with op_construct This could also work with native function, but not when they are called with QScriptValue::call() or QScriptValue::construct()
* Remove QScriptContextPrivate, QScriptContext is now a JSC::CallFrameOlivier Goffart2009-07-315-133/+80
| | | | | | | | | | | | | | 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

* QScriptValueIterator: fix missing non-enumerable valuesTor Arne Vestbø2009-07-312-7/+7
| | | | | | | | | | Added an extra argument to JSObject::getPropertyNames() that specifies if the non-enumerable properties (those with the DontEnum attribute set) should be included or not. Tried looking at using a unsigned as an attribute-inclusion or exclusion filter, but the semantics of either the calling or the callee code would be very strange so I opted out.

* attempt to return something sensible in uncaughtExceptionBacktrace()Kent Hansen2009-07-301-4/+10
| | | | | | | | JSC doesn't provide a way to get the backtrace after the exception has happened (you can only get it at the point it's thrown, by installing a debugger). As a least effort, we try to use the uncaught exception to provide a 1-line backtrace (the filename and linenumber of the innermost call where the exception happened).

* Enter a scope when enterning a native function.Olivier Goffart2009-07-291-12/+22
| | | | | | | | | | | | | | so native function that would call engine->evaluate("var b = 'foo'); would not change the global object. The change in qscriptengine.cpp makes sure that the correct scope is used for the execution of QScriptEngine::evaluate. The changes in qscriptfunction.cpp push a new scope for native function calls.

* make QScriptEngine::setGlobalObject() work to some extentKent Hansen2009-07-273-26/+140
| | | | | | | | | | | | | | | | | | | | | | | | | 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 Hansen2009-07-275-43/+40
| | | | | | | | | | | 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).
