upload to US Standard region failing with 0.4.0

[astraw]

Hi,

A "meteor update" broke my previously working setup in which I configure slingshot with a --settings CLI argument containing the following (substituting my actual values):

{"AWSAccessKeyId": "my_key",
 "AWSSecretAccessKey": "my_secret_key",
 "S3Bucket": "my_bucket"}

In the browser JS console, the first error I see is:

OPTIONS https://my_bucket.s3-us-east-1.amazonaws.com/ net::ERR_NAME_NOT_RESOLVED

This arises in the line xhr.send(buildFormData()); in upload.js.

And indeed, the DNS name does not resolve. However, my_bucket.s3.amazonaws.com does resolve and, as far as I can tell, this was the name slingshot 0.3.0 would use.

So it seems, at least for my use of slingshot without setting the "region" variable, the code is now broken.

Hmm, yes, totally overlooked that AWS has a discrepancy there:

Region is "us-east-1", but the domain is:

s3.amazonaws.com (N. Virginia or Pacific Northwest)
s3-external-1.amazonaws.com (N. Virginia only)

As a workaround you can set a bucketUrl to "https://my_bucket.s3.amazonaws.com" while still leaving the region at "us-east-1".

I will push a fix soon though.
