Some registries (ECR) don't provide a `Docker-Upload-UUID` when creating
a blob. So we can't rely on that header. Fallback to reading it from the
URL.

I've found this logic being in a single method to be quite hard to get.
I believe extracting it makes it easier to read, as we can then more
easily see what the main method does and possibly ignore the intricacies
of `ResumeBlobUpload`.

When uploading segments to Swift, the registry generates a random file,
by taking the hash of the container path and 32-bytes of random data.
The registry attempts to shard across multiple directory paths, by
taking the first three hex characters as leader.
The implementation in registry, unfortunately, takes the hash of
nothing, and appends it to the path and random data. This results in all
segments being created in one directory.

Use mime.ParseMediaType to parse the media types in Accept header in manifest request. Ignore the failed ones.
Signed-off-by: Yu Wang <yuwa@microsoft.com>
This fixes registry endpoints to return the proper `application/json`
content-type for JSON content, also updating spec examples for that.
As per IETF specification and IANA registry [0], the `application/json`
type is a binary media, so the content-type label does not need any
text-charset selector. Additionally, the media type definition
explicitly states that it has no required nor optional parameters,
which makes the current registry headers non-compliant.

This adds a `draintimeout` setting under `HTTP`. Registry doesn't drain

context.App.repoRemover is single registry instance stored throughout
app run. It was wrapped in another remover when processing each request.
This remover happened to be remover got from previous request. This way
every remover created was stored in infinite linked list causing memory
leak. Fixing it by storing the wrapped remover inside the request context
which will get gced when request context is gced. This was introduced in
PR #2648.

OCI Image manifests and indexes are supported both with and without
an embeded MediaType (the field is reserved according to the spec).
Test storing and retrieving both types from the manifest store.
Signed-off-by: Owen W. Taylor <otaylor@fishsoup.net>
In the OCI image specification, the MediaType field is reserved
and otherwise undefined; assume that manifests without a media
in storage are OCI images or image indexes, and determine which
by looking at what fields are in the JSON. We do keep a check
that when unmarshalling an OCI image or image index, if it has
a MediaType field, it must match that media type of the upload.

This adds a configuration setting `HTTP.TLS.LetsEncrypt.Hosts` which can
be set to a list of hosts that the registry will whitelist for retrieving
certificates from Let's Encrypt. HTTPS connections with SNI hostnames
that are not whitelisted will be closed with an "unknown host" error.
It is required to avoid lots of unsuccessful registrations attempts that
are triggered by malicious clients connecting with bogus SNI hostnames.
NOTE: Due to a bug in the deprecated vendored rsc.io/letsencrypt library
clearing the host list requires deleting or editing of the cachefile to
reset the hosts list to null.

This removes the old global walk function, and changes all
the code to use the per-driver walk functions.
Signed-off-by: Sargun Dhillon <sargun@sargun.me>
This changes the Walk Method used for catalog enumeration. Just to show
how much an effect this has on our s3 storage:
Original:
List calls: 6839
real 3m16.636s
user 0m0.000s
sys 0m0.016s
New:
ListObjectsV2 Calls: 1805
real 0m49.970s
user 0m0.008s
sys 0m0.000s
This is because it no longer performs a list and stat per item, and instead
is able to use the metadata gained from the list as a replacement to stat.

Move the Walk types into registry/storage/driver, and add a Walk method to each
storage driver. Although this is yet another API to implement, there is a fall
back implementation that relies on List and Stat. For some filesystems this is
very slow.
Also, this WalkDir Method conforms better do a traditional WalkDir (a la filepath).
This change is in preparation for refactoring.

The previous code assumed that the link returned when listing tags was
always absolute. However, some registries, such as quay.io, return the
link as a relative link (e.g. the second page for the quay.io/coreos/etcd
image is /v2/coreos/etcd/tags/list?next_page=<truncated>&n=50). Because
the relative link was retrieved directly, the fetch failed (with the
error `unsupported protocol scheme ""`).

A statically hosted registry that responds correctly to GET with a
manifest will load the right digest (by looking at the manifest body and
calculating the digest). If the registry returns a HEAD without
`Docker-Content-Digest`, then the client Tags().Get() call will return
an empty digest.
This commit changes the client to fallback to loading the tag via GET if
the `Docker-Content-Digest` header is not set.

AuthorizeRequest() injects the 'pull' scope if `from` is set
unconditionally. If the current token already has that scope, it will
be inserted into the scope list twice and `addedScopes` will be set to
true, resulting in a new token being fetched that has no net new scopes.
Instead, check whether `additionalScopes` are actually new.
