| * Add QScriptString::toArrayIndex() functionKent Hansen2009-10-302-0/+31
| | | | | | | | | | | | | | | | | | | | Avoid hacking a custom toArrayIndex() in the example; instead provide an ECMA-compliant conversion that's as fast as possible (having to convert the QScriptString to a QString and then convert the result to a number is considerably slower than calling JSC's Identifier::toArrayIndex() function directly).

* Say hello to QScriptProgram :-)Kent Hansen2009-10-287-58/+510
| | | | | | | | | | | 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

* Avoid calls to public QScriptValue::engine() functionKent Hansen2009-10-233-16/+31
| | | | | | | | | | Calls to engine() are mostly done for checking that the "source" and "target" engines are the same, but we don't want those checks to slow us down. Use an inline getEngine() function instead. This makes e.g. QScriptValue::call() ~10% faster for a function like "function(a, b) { return a + b; }". Reviewed-by: Olivier Goffart
* Speed up QScriptValue creation by avoiding operator= to be calledKent Hansen2009-10-231-32/+18
| | | | | | | | For non-object values, just return the value immediately; there is no way that the later check (result.isObject()) will be true anyway. This makes qScriptValueFromValue() ~50% faster. Reviewed-by: Olivier Goffart
* Bind QScriptValue to engine when the value is created internallyKent Hansen2009-10-231-26/+27
| | | | | | | | Makes creation+destruction of the QScriptValue a lot faster because it uses the engine's pool of QScriptValuePrivates instead of qMalloc()/qFree(). Reviewed-by: Olivier Goffart
* Inline internal property lookup functionKent Hansen2009-10-233-28/+47
| | | | | | | | | Also avoid looking up the object's own properties twice (before we called getOwnPropertySlot() and then getPropertySlot() on the same object). Makes QScriptValue::property() ~20% faster when calling it on an "empty" object. Reviewed-by: Olivier Goffart

* Use the qsreal type instead of double when working with QtScript numbersKent Hansen2009-10-224-7/+7
| | | | | | | | 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

* QScript: do not crash on PowerPCOlivier Goffart2009-10-061-2/+2
| | | | | | | | | | | | | | | There is no 'this' register in the global context. The computation of the this register for the global context gives the 'codeBlock' register in the frame header. On Intel processor, a JSValue() is 0x0 when converted to a pointer, but this is not the case on PowerPC (it is 0xfffffff9) so it just crash later when acessing the code block. Solution: special condition for the global context when getting the 'this' object Reviewed-by: Kent Hansen

* Reset timeout-checker before evaluating when processEventsInterval is usedKent Hansen2009-10-011-0/+2
| | | | | | | | | | | | | | | | When the timeout-checker was not reset, it could take a while (e.g. 1-2 seconds) before the next timeout occurred, depending on what the tick counter happened to be after the previous evaluate(). When a processEventsInterval of e.g. 100 milliseconds has been specified, we want the timeout to happen much sooner, thus we need to reset the checker. This will cause the first timeout to happen quickly, and then at steady intervals (processEventsInterval ms) after that. The tst_QScriptEngine::processEventsWhileRunning() test was sporadically failing due to this issue. Reviewed-by: Olivier Goffart

* initialize the this-register of the global contextKent Hansen2009-09-181-0/+1
| | | | | | | | | | | QScriptEnginePrivate::thisForContext() relies on the this-register of the global context to contain an invalid JSValue. The default Register constructor (used to initialize the registers of the global context) only invalidates its value when NDEBUG is not defined (but we define it). Therefore, we must explicitly set the this-register to an invalid value. Reviewed-by: Olivier Goffart
