Bug 3327 – Exception When Setting Style to Invalid Value Lacks Line/File Information

• Status: VERIFIED
• Resolution: FIXED
• Component: JavaScriptCore

[Mark Rowe (bdash)]

When an Javascript exception is raised due to setting a CSS property to an invalid value, the exception 
object lacks line number and file information.

To Reproduce:  Load the above URL in Safari, and check the Javascript Console.  An exception titled 'CSS 
exception 0' is listed with a URL of 'undefined' and line number of 0.

Excepted behaviour:  The Javascript console should contain an exception with the correct URL, http://
bdash.net.nz/files/safari-js-error.html, and line number of 4.

Retrieve the line number + source URL from the current node if an exception is found during KJS_CHECKEXCEPTIONVALUE.

Updated patch using local variable to reduce duplication of effort.

Patch updated as requested.  I ran run-webkit-tests earlier after creating my
initial patch, and everything looked ok.  I've pulled in the changes to the
Xcode project files since then though and the tests no longer build so I cannot
verify them with this latest patch applied.
