Add hook/callback/event to be fired when raven has reported an error to sentry

[bisrael]

I've been trying to add custom error handling to sometimes reload a page when a particular type of error occurs, but I'd also like to report that through raven to sentry.

My current way of accomplishing this is by exposing the private TraceKit used by Raven through a Raven.TK variable.

This is sort of sub optimal, though, since TraceKit does all sorts of weird stuff if you're on IE, etc, and I'm not always guaranteed that my tracekit handler will be called before Raven's TK handler.

It also requires me to know that Raven uses TK and how TK works.

In reality, all I need to know is that Raven has caught an error, and successfully reported it Sentry, and also ideally the error it reported.

Then I could let Raven handle errors, report them, and when it's done, look at the error and try reloading.

Thanks.

You want a callback for after the http request has been made, just to clarify? Right now, we just blindly fire and forget. :) The only reason I ask, is I'm not sure how hooking into TraceKit at all would satisfy this, since TraceKit isn't aware of us actually doing anything with the message.

That's my point, it doesnt really solve the problem.
I hooked into trace kit as a proxy for when raven has probably fired, since i hook in after raven.install, i should get called just after raven fires off the request, i also do a small timeout for good measure.

Ideally, we'd be notified whether the request failed or succeeded.
It would be nice to be able to retry failed requests.
Not sure how this would get accomplished since you use Image().src

TL;DR: yes.

[mattrobenolt]

It'd be possible. Image objects have callbacks like, onload and onerror that I can hook up to. If anything, I'd literally just expose those for you.

[bisrael]

That would be great.

I agree. A callback mechanism would be very helpful. Please make it compatible with the "global" error handler. Maybe it could be passed into the Raven.config options object.

Raven.config('https://[email protected]/1').install()

[mattrobenolt]

How about dispatching events instead? I'm more of a fan of events instead of callbacks.

[mattrobenolt]

Something like:

Raven.config('...').install().addEventListener('logged', function() { });

searching the source of the current master repo says "yes"
