6beeb935cd Avoid stat round-trips when fetching a blob
Without this commit, three round-trips are required to fetch a blob with
a progress bar. The first is a call to Stat (HEAD request), to determine
the size. Then Open is called, which also calls Stat, and finally
performs a GET request.

Only the GET request is actually needed. The size of the blob can be
sniffed from Content-Length in the GET response.

This commit changes HTTPReadSeeker to automatically detect the size from
Content-Length instead of requiring it to be passed in. The Stat call is
removed from Open because it is no longer necessary.

HTTPReadSeeker now takes an additional errorHandler callback argument which
translates an unsuccessful HTTP response into an appropriate API-level
error. Using a callback for this makes it possible to avoid leaking the
repsonse body to Read's caller, which would make lifecycle management
problematic.

Fixes #1223

6664a1384e Fix empty delete requests with Swift fs driver
The Delete method lists objects under the given path and tries to delete
all of them with a bulk delete request. If the path has no objects
underneath it, the body of this request will be empty, which causes
HTTP-level issues. Specifically, Go's HTTP client senses the empty
request buffer and doesn't include a Content-Length, which causes the
Swift server to fail the request.

This commit fixes the problem by avoiding sending empty bulk delete
requests. This is the correct thing to do anyway, since there's no
reason to request deletion of zero objects.

9637cb40cd Fix for issue 664: https://github.com/docker/distribution/issues/664
Errors thrown by storage drivers don't have the name of the driver, causing user
confusion about whether the error is coming from Docker or from a storage driver.
This change adds the storage driver name to each error message.

This required changing ErrUnsupportedDriver to a type, leading to code changes
whenever ErrUnsupportedDriver is used.  The tests check whether the driver name
appears in the error message.

f8c09b6a7d Add a new reference package abstracting repositories, tags and digests
There seems to be a need for a type that represents a way of pointing
to an image, irrespective of the implementation.

This patch defines a Reference interface and provides 3 implementations:
- TagReference: when only a tag is provided
- DigestReference: when a digest (according to the digest package) is
  provided, can include optional tag as well

Validation of references are purely syntactic.

There is also a strong type for tags, analogous to digests, as well
as a strong type for Repository from which clients can access the
hostname alone, or the repository name without the hostname, or both
together via the String() method.

For Repository, the files names.go and names_test.go were moved from
the v2 package.

74c32a0a51 Allow hostname components in component names.
Fixes https://github.com/docker/distribution/issues/1062

This relaxes the naming restrictions places on Docker images to permit
valid hostnames according to [RFC-2396](https://www.ietf.org/rfc/rfc2396.txt).

It deviates from the RFC in the following ways:
 1) Allow underscores where we allow hyphens (hostnames don't allow
 underscores, which we must for backwards compatibility).
 2) Leave "top-level" name segments unrestricted (domains require an
 alpha character to begin a top-level domain, e.g. "com").
 3) DO NOT allow a trailing dot, as permitted by FQDNs.

26d8344872 Remove initial access check from S3 driver
In the S3 storage driver there is currently an initial access permission check by listing the bucket. If this check fails, registry will panic and exit.

However, this check is broken in two ways. First of all it strips the final slash from the root directory path, meaning that any access permissions which limit access to a single directory will fail, because S3 treats the path as strict prefix match. Secondly it fails to strip any leading slash that might be present, unlike the other access places, which means that the path used is different as a leading slash is allowed and significant in a filename in S3.

Since there is also a periodic health check which correctly checks access permissions and shows the error more cleanly, the best solution seems to be to just remove this initial access check.

dbbcf5fe42 Functional options for NewRegistryWithDriver
Clean up calling convention for NewRegistryWithDriver to use functional
arguments.

This is a first step towards the refactor described in #215. I plan to
add additional options in the process of moving configurable items from
the App structure to the registry structure.

0e7462f1dd Fix CloseNotifier handling and avoid "the ResponseWriter does not implement CloseNotifier" warnings in logs
A change in #763 to address review comments caused problems. Originally,
instrumentedResponseWriter implemented the CloseNotifier interface, and
would panic if it was wrapping something that did not implement that
interface. This was split into a separate instrumentedResponseWriterCN
type that implements CloseNotifier, so there's a fallback if
instrumentedResponseWriter ever needs to wrap something that does not
implement this interface.

instrumentedResponseWriter's Value method would end up upcasting either
type back to instrumentedResponseWriter, which does not implement the
interface. In effect, instrumentedResponseWriterCN was never visible to
the handler.

This fixes the problem by implementing a wrapper Value method for
instrumentedResponseWriterCN.

98d9b5f589 Fix tests after #846
Change checkResponse to only expect the configured
X-Content-Type-Options header if it doesn't receive a 405 error, which
means the handler isn't registered for that method.

641cdf3ba6 Remove pathMapper object
The use of the pathMapper is no longer needed the way we have organized the
code base. The extra level of indirection has proved unnecessary and confusing
so we've opted to clean it up. In the future, we may require more flexibility,
but now it is simply not required.

06a098c632 Maintain manifest link compatibility
Unfortunately, the 2.1 releease has written manfiest links into the wrong
directory. This doesn't affect new 2.1 deployments but fixing this to be 2.0
backwards compatible has broken 2.1.0 compatibility. To ensure we have
compatibility between 2.0, 2.1.0 and future releases, we now check one of
several locations to identify a manifest link.

d00586de9f Use correct path for manifest revision path
Unfortunately, the refactor used the incorrect path for manifest links within a
repository. While this didn't stop the registry from working, it did break
compatibility with 2.0 deployments for manifest fetches.

Tests were added to ensure these are locked down to the appropriate paths.

6ba799b69e Provide simple storage driver health check
To ensure the ensure the web application is properly operating, we've added a
periodic health check for the storage driver. If the health check fails three
times in a row, the registry will serve 503 response status for any request
until the condition is resolved. The condition is reported in the response body
and via the /debug/health endpoint.

To ensure that all drivers will properly operate with this health check, a
function has been added to the driver testsuite.

When using the RADOS driver, the hierarchy of the files is stored

was returning an error instead of returned the first level files
stored. This patches creates an OMAP for "/" and excludes the listed

10f602b158 Don't panic when a http.ResponseWriter does not implement CloseNotifier
Instead, provide a variant of instrumentedResponseWriter that does not
implement CloseNotifier, and use that when necessary. In
copyFullPayload, log instead of panicing when we encounter something
that doesn't implement CloseNotifier.

This is more complicated than I'd like, but it's necessary because
instrumentedResponseWriter must not embed CloseNotifier unless there's
really a CloseNotifier to embed.

94935f39bc Add pull through cache functionality to the Registry which can be configured
with a new `proxy` section in the configuration file.

Create a new registry type which delegates storage to a proxyBlobStore
and proxyManifestStore.  These stores will pull through data if not present
locally.  proxyBlobStore takes care not to write duplicate data to disk.

Add a scheduler to cleanup expired content. The scheduler runs as a background
goroutine.  When a blob or manifest is pulled through from the remote registry,
an entry is added to the scheduler with a TTL.  When the TTL expires the
scheduler calls a pre-specified function to remove the fetched resource.

Add token authentication to the registry middleware.  Get a token at startup
and preload the credential store with the username and password supplied in the
config file.

Allow resumable digest functionality to be disabled at runtime and disable
it when the registry is a pull through cache.
