You're not asking how you can implement monkey-patching; you're asking how you can stop/limit/blacklist/undo/circumvent it because it's harmful. The way I see it, the platform is shooting itself in the foot, repeatedly, but it gets angry at us when we suggest to take away its gun.

Then you can restore that as necessary when control comes back to your code. It should be possible to package this behavior relatively nicely; maybe a custom alternate global object helps (so you wouldn't have to restore anything, you'd just mechanically s/Array/original_global.Array/g in your code). You don't need proxies for this, nor any other way to observe what the extension is mucking with. > Cheers, > Ben. > > -- > -- > v8-users mailing list > [email protected] > http://groups.google.com/group/v8-users > --- > You received this message because you are subscribed to the Google Groups > "v8-users" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to [email protected]. > For more options, visit https://groups.google.com/groups/opt_out. > > > -- -- v8-users mailing list [email protected] http://groups.google.com/group/v8-users --- You received this message because you are subscribed to the Google Groups "v8-users" group.
