959408 - don't print the contents of huge arrays

Status: RESOLVED DUPLICATE of bug 1270179

(DevTools :: Object Inspector, defect)

Description

[(not reading bugmail) Nick Desaulniers [:\n]]

Example, an ImageData object.  You can get such an object by calling createImageData on a CanvasRenderingContext2D instance.  By clicking on a logged object, the box of values appears on the right, then freezes up FF.  We probably should print all of the values of a huge array, or at least do so asynchronously.

Victor, don't we use paging for large arrays? Could it be that our heuristics need some more fine-tuning?

Maybe we're missing something in our heuristics, definitely.

Nick, can you please post a small test-case? Also, more importantly, what version of Firefox are you running?
