Bug 148591 – JSCallbackData::invokeCallback() should return the Exception to the caller

• Component: Bindings
• Status: RESOLVED FIXED

[Chris Dumez]

JSCallbackData::invokeCallback() calls a callback function. If this function throws an exception, it will report it and clear it on the VM.
However, in the case of NodeFilter, the DOM specification clearly states that we are supposed to rethrow the exception [1].

Once way to support this is to have JSCallbackData::invokeCallback() return the Exception to the caller and let the caller decide what to do with it (i.e. report it or rethrow it).

This broke bindings tests: https://build.webkit.org/builders/Apple%20Yosemite%20Release%20WK2%20%28Tests%29/builds/7914/steps/bindings-generation-tests/logs/stdio

I'm going to land current results as expected (and to once again wonder if having bindings tests is worth the effort).

Sorry about that, I completely forgot. And thanks for fixing it for me.
