This change ports the client use the URLBuilder to create urls. Without this,
it produces broken urls for certain use cases. The client has also been updated
to no longer use the size argument to complete blob uploads. Much of this work
has been done after testing with the staging registry instance.
During client implementation, it was found that requiring the size argument
made client implementation more complex. The original benefit of the size
argument was to provide an additional check alongside of tarsum to validate
incoming data. For the purposes of the registry, it has been determined that
tarsum should be enough to validate incoming content.
At this time, the size check is optional but we may consider removing it
completely.
URL values may be required to complete an upload in a single POST request,
which may include digest and size. This is not implemented in the server side,
yet, but is part of the HTTP API specification.
Routes and errors are now all referenced from a single v2 package. This
packages exports are acceptable for use in the server side as well as
integration into docker core.
To provide a single package with v2 API definitions, the locked down portions
of the API have been merged into a single package. References to exported items
will appear as v2.XXX, indicating their origin. The definitions in this package
will soon be locked down for change, acceppting only additions that will not
change protocol behavior.
The URLBuilder is now exported with documentation for its behavior. Its a light
wrapper around gorilla mux that avoids one having to remember exact arguments
take by each route.
This simply moves the registry app to be using the urls package and its
exported route names. This supports locking down exported route definitions for
use in client packages.
To lock down V2 api routing, we are moving it to a separate package, with an
exported router creation function and route names. Updates will follow to
prepare the package for export.
Requires all paths in the inmemory and filesystem drivers to begin with
a slash, and then contain only valid path components (2+ alphanumeric
characters with optional period, hyphen, and underscore separators)
delimited by slashes.
Also updates the storage driver test suites to construct paths of this
format, and causes the suite to abort if files are not cleaned up after
the test run.
This implements a base endpoint that will respond with a 200 OK and an empty
json response. Such an endpoint can be used as to ping the v2 service or as an
endpoint to check authorization status.
During the specification period, it was suggested that pluralized object names
are more idiomatic in APIs than singular. This changeset simply adopts that
preference for the API going forward. The client has been updated to remain
compatible.
To support accurate specification generation, this changeset includes a quick
and dirty tool to generate a markdown table of error codes generated by the
registry API. Equivalent supports for routes will likely follow.
Exported descriptors could be used to generate other documentation, as well.
Also makes this test respect the Short flag, reducing the number of
threads by a factor of 4 and space usage by a factor of 16
Note: this test is probably unreasonable to run on the inmemory driver
without the Short flag
This commit locks down the set of http error codes that will be part of the
inital V2 specification, proposed in docker/docker#9015. The naming order has
been slightly changed and there are few tweaks to ensure all conditions are
captured but this will be set the docker core will be impleemnted against.
To support this, the errors have been moved into an api/errors package. A new
type, ErrorDescriptor, has been defined to centralize the code, message and
definitions used with each type. The information therein can be used to
generate documentation and response code mappings (yet to come...).
In addition to the refactoring that came along with this change, several tests
have been added to ensure serialization round trips are reliable. This allows
better support for using these error types on the client and server side. This
is coupled with some tweaks in the client code to fix issues with error
reporting.
Other fixes in the client include moving client-specific errors out of the base
package and ensuring that we have correct parameters for finishing uploads.
Creates trees instead of flat files for TestConcurrentFileStreams
Adds TestConcurrentStreamReads, which writes a large file (smaller in
Short mode), and then ensures that several concurrent readers properly
read their portions of the file with random offsets
Ensures that Move will properly overwrite the file at the destination
location.
Also checks that Move of a nonexistent source file will NOT delete the
file at the destination.
