Ok, try this one for Firefox 6. http://hashcollision.org/whalesong/racketcon/talk-firefox6.html --- Notes about what happened: ... ok, I'm seeing at least two issues with Firefox 6. One of this is my use of the 'arity' attribute for primitive functions, which I see is not playing well with Firefox 6's use of that attribute. Ugh, ok, so I will rename that in the internal runtime to avoid that issue. But one of them, though, appears to be a bug in Firefox 6. Firefox 6 is telling me that the innermost reference to successFunction is not lexically bound in the following code: //////////////////////////////////////////////////////////////////////////////////////// var adaptWorldFunction = function(worldFunction) { return function() { // Consumes any number of arguments. var successFunction = arguments[arguments.length - 1]; plt.baselib.functions.internalCallDuringPause.apply( null, [MACHINE, worldFunction, function(v) { successFunction(v); }, function(err) { // FIXME: do error trapping throw(err); }].concat([].slice.call(arguments, 0, arguments.length - 1))); } }; //////////////////////////////////////////////////////////////////////////////////////// However, if I change this to the following, Firefox 6 is happy: ////////////////////////////////////////////////////////////////////////////////////////////// var adaptWorldFunction = function(worldFunction) { var successFunction; return function() { // Consumes any number of arguments. successFunction = arguments[arguments.length - 1]; plt.baselib.functions.internalCallDuringPause.apply( null, [MACHINE, worldFunction, function(v) { successFunction(v); }, function(err) { // FIXME: do error trapping throw(err); }].concat([].slice.call(arguments, 0, arguments.length - 1))); } }; //////////////////////////////////////////////////////////////////////////////////////////////////// Good grief. As we Racketeers know, the first approach should have been perfectly ok too! I guess I'm trying to say this: this is not completely my fault. :) This looks like a Firefox 6 bug, and a serious one. Does anyone know how to submit a bug report to the Mozilla folks? I haven't patched Whalesong yet to regenerate the other code examples, but here's the talk slides for Firefox 6 that I fixed by hand: http://hashcollision.org/whalesong/racketcon/talk-firefox6.html _________________________________________________ For list-related administrative tasks: http://lists.racket-lang.org/listinfo/users
