* Fix alignment issue causing crash in QtScript/JavaScriptCoreKent Hansen2011-01-281-0/+25
| | | | | | | | | | | | | | | | When creating a substring, JSC::UStringImpl required that the base string pointer was 8-byte aligned. However, on platforms where FastMalloc isn't enabled (such as Symbian), it's possible that the system malloc() returns a pointer that is only 4-byte aligned. (On Symbian, this can happen if the argument to malloc() itself isn't a multiple of 8.) Cherry-picked http://trac.webkit.org/changeset/54743 from WebKit trunk, which fixes this issue. (The commit happened shortly after we rebased QtScript/JSC for 4.7, so it applies cleanly to our copy.) Task-number: QTBUG-16828 Reviewed-by: Simon Hausmann

| | | | | | | | This reverts commit 7db489a0de073a2a56fe32d16f1cbe1bebdfd06d. The change to CollectorHeapIterator.h is not Symbian-specific and it introduced test failures on all platforms (tst_QScriptEngineAgent::positionChange_3()).

| | | | | | | | | | | | | Backport of Jay's patch from https://bugs.webkit.org/show_bug.cgi?id=34349 with minor modifications. Even though the original patch was rejected upstream and has been superseded by the patches for https://bugs.webkit.org/show_bug.cgi?id=43185, those patches are more involved (affecting all platforms), hence difficult/risky to backport.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Update qscriptvalueiterator test to expect length property when iterating arrays and strings. - Use EvalExecutable::create() instead of EvalExecutable constructor. The constructor is private. - Reimplement getOwnPropertyDescriptor() in all custom script objects. - Remove all reimplementations of getPropertyAttributes(). It doesn't exist in trunk anymore (getOwnPropertyDescriptor() is used instead). - Remove checkDontDelete argument from deleteProperty() reimplementations. The purpose of this argument was to support deleting properties with attribute Undeletable from C++. But it was quite an invasive patch to JavaScriptCore, and it doesn't seem worth it. If this feature is really crucial it should be re-done upstream. One of the tests needed to be updated so it's not sensitive to the C++ undeletability. - Adapt getOwnPropertyNames() reimplementations to signature change. - Add missing QScriptObject structure flags, otherwise we don't get all virtual calls. - Remove our patch for reporting column numbers in the debugger callbacks. It was just too intrusive. As with the checkDontDelete issue, this should be redone upstream if it's really important. In 4.7, QScriptEngineAgent will always report a column number of 1. Other compilation fixes: - InternalFunction::name() takes an ExecState* argument, not GlobalData* - ScopeChain::globalObject is no longer a function but a member variable - ScopeChainNode constructor takes a GlobalObject argument - Heap::collect() is called collectAllGarbage() - JSValue::strictEqual() takes an ExecState* argument - Debugger::exception() takes a bool hasHandler argument - Debugger no longer reports column number (we decided to drop that patch from JSC) - UString doesn't have operator+=(char*) - Update the autotests to reflect the columnNumber=1 change. - Add helper class to avoid crashing inside JSC. Ever since r52856 in WebKit trunk, this is needed. There are probably a lot of other public API functions that need this guard as well, but I'll add them as they are discovered. - Update mkdist-javascriptcore tag, exclude a few more files. - Set ENABLE_JSC_MULTIPLE_THREADS=0 define on Mac due to r52355 in trunk.
