Globally catch nodejs exceptions

[Chris Granger]

With 0.3.5, uncaught nodejs exceptions now show a screen with a cloud on it and a stacktrace. Is there a way to intercept this behavior to replace it with my own? I don't want a bug in a plugin for example destroying the state of the application, such that people might lose work. I'd much rather handle this with some global catchall. I used to do that by adding an event handler for uncaughtException, but that doesn't prevent the clouds from taking over.

Cheers,
Chris.

Thanks for your comments. We didn't expect this to break the applications when we add this feature. And we'd like to fix it ASAP.

btw, could you please provide your code of adding an event handler for uncaughtException? We can add it to our test cases.

I'll prevent nw from printing stacktrace when there are other
listeners of uncaughtException.

Not doing anything fancy with it, the ClojureScript code looks like this:

(.on js/process "uncaughtException" #(error %))

The equivalent js would be something like

process.on("uncaughtException", function(err) { alert("error: " + err); });

Cheers,
Chris.
