869459 - Indicate we're going up the callstack because of an exception when stepping

Status: RESOLVED WORKSFORME

(DevTools :: Debugger, enhancement)

Description

[:Gijs (he/him)]

Currently, if you step through code and the code throws an exception, at each step you go up the callstack one frame at a time, highlighting the last line of each function every time.

This can be highly confusing if you did not expect an exception to be thrown (eg. bug 867880).

It would be nice if we provided visual feedback about whether we're in "normal" code flow or if we're showing you an exception traveling up the callstack. Ideas include changing the color of the line highlight, showing a notification bar with exception details, or showing the exception above the watches/locals pane.

Should be fixed in bug 773590, feel free to reopen and provide more info if you feel otherwise.
