This package was forked from the https://github.com/distribution/distribution repository in commit901bcb2231, but that commit did a plain copy of the code (minus tests), and rewrote the code to be in a single file. The same commit also removed some deprecated code for handling "shortid" references (ParseAnyReferenceWithSet() function), in order to avoid the "digestset" dependency from the distribution repo. At the time, containerd used the distribution/distribution package from this commit:0d3efadf01Since the code was forked, both containerd and distribution have received improvements and fixes, so unfortunately, the code started to diverge. I'm planning to reconcile the packages (potentially by using a shared module), and this is the first commit to assist with that. This patch restructures the reference/docker package to split the code into the same files as are used in the upstream distribution/distribution repository. This makes it easier to compare the implementations in both repositories (to allow synchronizing changes). No changes are applied yet, other than splitting the code (follow-up commits will take care of syncing changes across). Signed-off-by: Sebastiaan van Stijn <github@gone.nl>
