0bb696c5bf add test for manifest handler where storage driver fails

2e94c22fe4 issue#2135 image pull returns 404 on manifest request if there is storage error
When get manifest, the handler will try to retrieve it from storage driver. When storage driver is cloud storage, it can fail due to various reasons even if the manifest exists
(like 500, 503, etc. from storage server). Currently manifest handler blindly return 404 which can be confusing to user.

This change will return 404 if the manifest blob doesn't exist, and return 500 UnknownError for all other errors (consistent with the behavior of other handlers).

ccb839e0e3 Change DELETE action from "*" to "delete"
With token authentication, requiring the "*" action for DELETE requests
makes it impossible to administratively lock a repository against pushes
and pulls but still allow deletion.  This change adds a new "delete"
action for DELETE requests to make that possible.

8e915d69f4 Use app.driver.Stat for registry health check
`app.driver.List` on `"/"` is very expensive if registry contains significant amount of images. And the result isn't used anyways.
In most (if not all) storage drivers, `Stat` has a cheaper implementation, so use it instead to achieve the same goal.

manifest: references should cover all children
To allow generic manifest walking, we define an interface method of
`References` that returns the referenced items in the manifest. The
current implementation does not return the config target from schema2,
making this useless for most applications.

The garbage collector has been modified to show the utility of this
correctly formed `References` method. We may be able to make more
generic traversal methods with this, as well.

ad6bb66faf Add notification filtering by target media type
The Hub registry generates a large volume of notifications, many of
which are uninteresting based on target media type.  Discarding them
within the notification endpoint consumes considerable resources that
could be saved by discarding them within the registry.  To that end,
this change adds registry configuration options to restrict the
notifications sent to an endpoint based on target media type.

8907f7d189 Update "Accept" header parsing for list values
In Go's header parsing, the same header multiple times results in multiple entries in the `r.Header[...]` slice, but Go does no further parsing beyond that (and in https://golang.org/cl/4528086 it was determined that until/unless the stdlib itself needs it, Go will not do so).

The consequence here for parsing of `Accept:` headers is that we support the way Go outputs headers, but not all language HTTP libraries have a facility to output multiple headers instead of a single list header.

This change ensures that the following (valid) header blocks all parse to the same result for the purposes of what is being tested here:

```
Accept: a/b
Accept: b/c
Accept: d/e
```

```
Accept: a/b; q=0.5, b/c
Accept: d/e
```

```
Accept: a/b; q=0.1, b/c; q=0.2, d/e; q=0.8
```

cb6f002350 Implementation of the Manifest Service API refactor.
Add a generic Manifest interface to represent manifests in the registry and
remove references to schema specific manifests.

Add a ManifestBuilder to construct Manifest objects. Concrete manifest builders
will exist for each manifest type and implementations will contain manifest
specific data used to build a manifest.

Remove Signatures() from Repository interface.

Signatures are relevant only to schema1 manifests.  Move access to the signature
store inside the schema1 manifestStore.  Add some API tests to verify
signature roundtripping.

schema1
-------

Change the way data is stored in schema1.Manifest to enable Payload() to be used
to return complete Manifest JSON from the HTTP handler without knowledge of the
schema1 protocol.

tags
----

Move tag functionality to a seperate TagService and update ManifestService
to use the new interfaces.  Implement a driver based tagService to be backward
compatible with the current tag service.

Add a proxyTagService to enable the registry to get a digest for remote manifests
from a tag.

manifest store
--------------

Remove revision store and move all signing functionality into the signed manifeststore.

manifest registration
---------------------

Add a mechanism to register manifest media types and to allow different manifest
types to be Unmarshalled correctly.

client
------

Add ManifestServiceOptions to client functions to allow tags to be passed into Put and
Get for building correct registry URLs.  Change functional arguments to be an interface type
to allow passing data without mutating shared state.

always nil.

I verified that none of the hash.Hash implementations in the standard
library can return an error on Write. Nor can any of the hash.Hash
implementations vendored in distribution.

This commit changes digest.FromBytes not to return an error. If Write
returns an error, it will panic, but as discussed above, this should
never happen.

This commit also avoids using a bytes.Reader to feed data into the hash
function in FromBytes. This makes the hypothetical case that would panic
a bit more explicit, and should also be more performant.

dd32fbe615 Before allowing a schema1 manifest to be stored in the registry, ensure that it
contains equal length History and FSLayer arrays.

This is required to prevent malformed manifests being put to the registry and
failing external verification checks.

76624704c3 Correct unmarshal order for SignedManifest
To ensure that we only unmarshal the verified payload into the contained
manifest, we first copy the entire incoming buffer into Raw and then unmarshal
only the Payload portion of the incoming bytes. If the contents is later
verified, the caller can then be sure that the contents of the Manifest fields
can be trusted.

This allows the administrator to specify an externally-reachable URL for
the registry. It takes precedence over the X-Forwarded-Proto and

530afa5234 Add WithVersion to context and other cleanup
By adding WithVersion to the context package, we can simplify context setup in
the application. This avoids some odd bugs where instantiation order can lead
to missing instance.id or version from log messages.

6712e602b0 Move manifest package to schema1
As we begin our march towards multi-arch, we must prepare for the reality of

facilitate this. We are both moving this package into its target position where
it may live peacefully next to other manfiest versions.

b9b9cafa8f Expose a Registry type in health package, so unit tests can stay isolated from each other
Update docs.

Change health_test.go tests to create their own registries and register
the checks there. The tests now call CheckStatus directly instead of
polling the HTTP handler, which returns results from the default
registry.

b09b0ffcf9 Add configurable file-existence and HTTP health checks
Add a section to the config file called "health". Within this section,
"filecheckers" and "httpcheckers" list checks to run. Each check
specifies a file or URI, a time interval for the check, and a threshold
specifying how many times the check must fail to reach an unhealthy
state.

Document the new options in docs/configuration.md.

Add unit testing for both types of checkers. Add an UnregisterAll
function in the health package to support the unit tests, and an
Unregister function for consistency with Register.

Fix a string conversion problem in the health package's HTTP checker.
