635829 - Fix callingScript -> filename in error messages and jsdIScript objects

Status: RESOLVED INACTIVE

(Core :: XPConnect, defect)

Description

[John J. Barton]

If you get this in the error console you can't view source; if you get this from jsd you can't debug it:

Error: swarm.bootstrap startup
Source File: resource://gre/modules/XPIProvider.jsm -> file:///C:/Users/johnjbarton/firebug/fbug/fbug/extensions/swarm/branches/swarm1.7/bootstrap.js
Line: 1


> Is there someone we can convince to stop doing this?

Boris:

Maybe.  The prefixing is a security fix, because some parts of the JS engine just looked at the beginning of the script's filename to determine some security properties.

It may be that we no longer need this in the new wrapper setup.  Please file a bug on xpconnect and make sure Blake is cced?

-Boris

P.S.  The code that does this is in mozJSSubScriptLoader::LoadSubScript; look for 'prepend the filename with the filename of the calling script, and " -> "' 


I can make a test case by calling Cu.reportError() in bootstrap.js FF4.0.
