Description
(reported by neonstalwart)
script tag in page
require({
baseUrl: './',
paths: {
multiple: 'multiple',
duplicate: 'multiple'
}
}, ['multiple', 'duplicate'], function (multiple, duplicate) {
multiple.multi = true;
console.log('multiple', multiple.multi);
console.log('duplicate', duplicate.multi);
});
multiple.js
console.log('loaded');
define(function (require, exports, module) {
console.log('defined', module.id);
return {};
});
i'd expect to see the following in the console:
loaded defined multiple defined duplicate multiple true duplicate undefined
the loader appears to not do this

@neonstalwart: Why wouldn't you expect multiple.js to be evaluated twice, thereby causing two console.log("loaded') calls?

Looking into this a bit further, it seems like the precise behavior is undefined according to the AMD spec. Further, the loader is behaving consistent with https://github.com/jrburke/requirejs/blob/master/tests/urlfetch/urlfetch.html.
For my taste, I don't like this behavior. If two different modules are mapped to the same resource, then the best practice is for that resource should have a single anon define. But what if it doesn't as per the test above?
fwiw, here is how to rewrite the test to get the "correct" effect:
<html>
<head>
<script type="text/javascript" src="../../../dojo.js" data-dojo-config="async:1"></script>
<script type="text/javascript">
require({
baseUrl: './',
paths: {
multiple: 'multiple',
duplicate: 'multiple'
},
packages: [{
name:"p1",
location:".",
},{
name:"p2",
location:".",
paths:{"p2/duplicate":"multiple"}
}]
}, ['p1/multiple', 'p2/duplicate'], function (multiple, duplicate) {
multiple.multi = true;
console.log('multiple', multiple.multi);
console.log('duplicate', duplicate.multi);
});
</script>
</head>
</html>
Owing to the lack of a standard for this dusty corner, I'm not going to address this in 1.x.
