V4 support for Phabricator's S3 File backend
Closed, DuplicatePublic

Description

Right now it seems that the library Phabricator uses for S3 is quite outdated and it doesn't support the Amazon V4 authentication scheme (http://docs.aws.amazon.com/AmazonS3/latest/API/sig-v4-authenticating-requests.html). This is sadly the only available authentication scheme for the EU-Central region and since we've deployed Phabricator there (for many reasons), we cannot really use S3 as the backing file store right now.

There's also the risk of AWS deprecating V2 before long since V4 has been out for quite a while by now. :)

I found it interesting that S3 got interpreted as remarkup. I wonder if we should blacklist it from being matched similar to Q1, etc.

I'm going to merge this into T5155 because I imagine that will be the way in which this is resolved.
