Search terms shouldn't be restricted to only full valid repository
names. It should be perfectly valid to search using a part of a name,
even if it ends with a period, dash or underscore.

This allows the administrator to specify an externally-reachable URL for
the registry. It takes precedence over the X-Forwarded-Proto and
X-Forwarded-Host headers, and the hostname in the request.

Associate HTTP 401s with Authentication errors rather than Authorization
errors. Changes the meaning of the UNAUTHORIZED error to be authentication
specific.
Defines DENIED error code to be associated with authorization
errors which result in HTTP 403 responses.
Add 'No Such Repository' errors to more endpoints.

The "testing" package adds some flags in its init function, so utilities
that import distribution code may print a page of extra testing flags in
their help output.
This commit solves the issue by moving an import of "testing" in the
registry/storage/cache package to a new
registry/storage/cache/cachecheck package, which is only imported by
tests.

Add a daemon flag to control this behaviour. Add a warning message when pulling
an image from a v1 registry. The default order of pull is slightly altered
with this changset.
Previously it was:
https v2, https v1, http v2, http v1
now it is:
https v2, http v2, https v1, http v1
Prevent login to v1 registries by explicitly setting the version before ping to
prevent fallback to v1.
Add unit tests for v2 only mode. Create a mock server that can register
handlers for various endpoints. Assert no v1 endpoints are hit with legacy
registries disabled for the following commands: pull, push, build, run and
login. Assert the opposite when legacy registries are not disabled.

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.

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.
Signed-off-by: Stephen J Day <stephen.day@docker.com>
This solves a issue from #909 where instance.id was not printed in logs,
because this file was using the background context from
golang.org/x/net/context instead of
github.com/docker/distribution/context.
It's cleaner to standardize on one package, so this commit removes the
import of golang.org/x/net/context entirely. The Context interfaces
defined in both packages are the same, so other code using
golang.org/x/net/context can still pass its context to NewRegistry.

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.

To bring ErrorCode into liine with Go conventions, ErrorCode.Error() now
returns the "nice" value of the error code. This ensures error message assembly
works similar to commonly used Go conventions when directly using ErrorCode as
an error.

Add default storagedriver health check to example configuration files
with parameters matching the previous hardcoded configuration.
Signed-off-by: Aaron Lehmann <aaron.lehmann@docker.com>
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.

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.

The use of the pathMapper is no longer needed the way we have organized the

so we've opted to clean it up. In the future, we may require more flexibility,

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.
