What am I missing - there seems to be no mechanism to catch or handle
exceptions when executing pure JS
Trying to support user definable scripts so I've no control over content.
Do I need to wrap it in try/catch blocks?
Then I need to consider an invisible mechanism to call from the catch()
handler, i.e. an exposed onerror function in the passed API object.
Seems a bit ugly, but I want to know if an error occured after frame.run()
called
Tracing through ses-single-frame.js for #5687 I can see at line 27106 that
an exception when compiledFunc() is called is not bubbled up.
Q.when(promise, function (compiledFunc) {
var result = compiledFunc(imports);
if (opt_runDone) {
opt_runDone(result);
}
}, function (failure) {
config.console.log('Failed to load guest content: ' + failure);
});
My code:
caja.initialize({
cajaServer: '/client/caja/',
maxAcceptableSeverity: 'NO_KNOWN_EXPLOIT_SPEC_VIOLATION',
debug: true,
es5Mode: true
});
var consoleService = {
log: function()
{
console.log.apply(console,arguments);
}
};
caja.markReadOnlyRecord(consoleService); // (2)
caja.markFunction(consoleService.log);
var tamedConsoleService = caja.tame(consoleService);
caja.load(undefined, undefined, function (frame)
{
var _api = { console: tamedConsoleService};
frame.code('/dummy.js','application/javascript',
'consolea.log("smoo")' ) <- throws exception as consolea undefined, unable
to detect
.api(_api)
.run(function ()
{
});
});
