getScript() neither calls done nor fail on Bad Gateway

Description

When using getScript

(as in:)

$.getScript(url)
.done(function(script, textStatus) {Logger.log(0, "loaded script:"+url);})
.fail(function(jqxhr, settings, exception) {Logger.log(1, "loading script failed! ("+url+") error:"+jqxhr.status+" exception:"+exception);
});

No function call will be made if the server answers with 502 (Bad Gateway)

That's because cross-domain requests are not guaranteed to notify errors as documented here (see the error option).

We're doing the best we can using script tag injection under the hood.

Okay, I don't want to stress this too much, but the problem is a bit different: There is no Cross-Domain Problem (for the Browser), as it loads another script from the same server. When triggering a cross-domain denial, fail is called, giving a 404 (at least in my example), which is fine. The Problem is, that the server returns a 502 Bad Gateway Page, which is even caught in my debugging console, but the getScript function neither calls fail NOR done, where I would expect that at least one of them get's called.

Then we need a minimal test case demonstrating the issue before we re-open this. I guess you cannot provide a jsfiddle or jsbin but could you have a page on one of your servers demonstrating the issue?

I have set up an example at http://devetopia.com/jtest/jquery_loadtest/test1.html

this test will try to load 3 js files - one from the same server, one from a different origin (which works) and one which gives bad gateway. Responses are logged in the middle box.

I'm quite surprised that the cross origin load works fine.

So the failing script actually __is__ cross-domain. Sometimes errors will be notified (like a 404), other times, however, the browser won't notify the error back up to the javascript (which is the case for the bad gateway).

There's nothing jQuery can do here.
