libcontainerd: Upgrade to typeurl/v2
In preparation for containerd v1.7 which migrates off gogo/protobuf and changes the protobuf Any type to one that's not supported by our vendored version of typeurl. This fixes a compile error on usages of `typeurl.UnmarshalAny` when upgrading to containerd v1.7. Signed-off-by: Paweł Gronowski <pawel.gronowski@docker.com>

"Derivative Works" shall mean any work, whether in Source or Object
|
||||
form, that is based on (or derived from) the Work and for which the
|
||||

||||
|
||||
(c) You must retain, in the Source form of any Derivative Works
|
||||
that You distribute, all copyright, patent, trademark, and
|
||||
attribution notices from the Source form of the Work,
|
||||
excluding those notices that do not pertain to any part of
|
||||
the Derivative Works; and
|
||||
|
||||
(d) If the Work includes a "NOTICE" text file as part of its
|
||||
distribution, then any Derivative Works that You distribute must

||||
within such NOTICE file, excluding those notices that do not
|
||||
pertain to any part of the Derivative Works, in at least one
|
||||
of the following places: within a NOTICE text file distributed
|
||||
as part of the Derivative Works; within the Source form or
|
||||
documentation, if provided along with the Derivative Works; or,
|
||||
within a display generated by the Derivative Works, if and
|
||||
wherever such third-party notices normally appear. The contents
|
||||
of the NOTICE file are for informational purposes only and

||||
do not modify the License. You may add Your own attribution
|
||||
notices within Derivative Works that You distribute, alongside
|
||||
or as an addendum to the NOTICE text from the Work, provided
|
||||
that such additional attribution notices cannot be construed
|
||||
as modifying the License.
|
||||
|
||||
You may add Your own copyright statement to Your modifications and
|
||||
may provide additional or different license terms and conditions
|
||||
for use, reproduction, or distribution of Your modifications, or
|
||||
for any such Derivative Works as a whole, provided Your use,
|
||||
reproduction, and distribution of the Work otherwise complies with
|
||||
the conditions stated in this License.
|
||||
|
||||
5. Submission of Contributions. Unless You explicitly state otherwise,
|
||||
any Contribution intentionally submitted for inclusion in the Work
|
||||
by You to the Licensor shall be under the terms and conditions of
|
||||
this License, without any additional terms or conditions.
|
||||
Notwithstanding the above, nothing herein shall supersede or modify
|
||||
the terms of any separate license agreement you may have executed
|
||||
with Licensor regarding such Contributions.
|
||||
|
||||
6. Trademarks. This License does not grant permission to use the trade
|
||||
names, trademarks, service marks, or product names of the Licensor,
|
||||
except as required for reasonable and customary use in describing the
|
||||
origin of the Work and reproducing the content of the NOTICE file.
|
||||
|
||||
7. Disclaimer of Warranty. Unless required by applicable law or
|
||||
agreed to in writing, Licensor provides the Work (and each
|
||||
Contributor provides its Contributions) on an "AS IS" BASIS,
|
||||
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
|
||||
implied, including, without limitation, any warranties or conditions
|
||||
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
|
||||
PARTICULAR PURPOSE. You are solely responsible for determining the
|
||||
appropriateness of using or redistributing the Work and assume any
|
||||
risks associated with Your exercise of permissions under this License.
|
||||
|
||||
8. Limitation of Liability. In no event and under no legal theory,
|
||||
whether in tort (including negligence), contract, or otherwise,
|
||||
unless required by applicable law (such as deliberate and grossly
|
||||
negligent acts) or agreed to in writing, shall any Contributor be
|
||||
liable to You for damages, including any direct, indirect, special,
|
||||
incidental, or consequential damages of any character arising as a
|
||||
result of this License or out of the use or inability to use the
|
||||
Work (including but not limited to damages for loss of goodwill,
|
||||
work stoppage, computer failure or malfunction, or any and all
|
||||
other commercial damages or losses), even if such Contributor
|
||||
has been advised of the possibility of such damages.
|
||||
|
||||
9. Accepting Warranty or Additional Liability. While redistributing
|
||||
the Work or Derivative Works thereof, You may choose to offer,
|
||||
and charge a fee for, acceptance of support, warranty, indemnity,
|
||||
or other liability obligations and/or rights consistent with this
|
||||
License. However, in accepting such obligations, You may act only
|
||||
on Your own behalf and on Your sole responsibility, not on behalf
|
||||
of any other Contributor, and only if You agree to indemnify,
|
||||
defend, and hold each Contributor harmless for any liability
|
||||
incurred by, or claims asserted against, such Contributor by reason
|
||||
of your accepting any such warranty or additional liability.

package typeurl
|
||||
|
||||
// Package typeurl assists with managing the registration, marshaling, and
|
||||
// unmarshaling of types encoded as protobuf.Any.
|
||||
//
|
||||
// A protobuf.Any is a proto message that can contain any arbitrary data. It
|
||||
// consists of two components, a TypeUrl and a Value, and its proto definition
|
||||
// looks like this:
|
||||
//
|
||||
// message Any {
|
||||
// string type_url = 1;
|
||||
// bytes value = 2;
|
||||
// }
|
||||
//
|
||||
// The TypeUrl is used to distinguish the contents from other proto.Any
|
||||
// messages. This typeurl library manages these URLs to enable automagic
|
||||
// marshaling and unmarshaling of the contents.
|
||||
//
|
||||
// For example, consider this go struct:
|
||||
//
|
||||
// type Foo struct {
|
||||
// Field1 string
|
||||
// Field2 string
|
||||
// }
|
||||
//
|
||||
// To use typeurl, types must first be registered. This is typically done in
|
||||
// the init function
|
||||
//
|
||||
// func init() {
|
||||
// typeurl.Register(&Foo{}, "Foo")
|
||||
// }
|
||||
//
|
||||
// This will register the type Foo with the url path "Foo". The arguments to
|
||||
// Register are variadic, and are used to construct a url path. Consider this
|
||||
// example, from the github.com/containerd/containerd/client package:
|
||||
//
|
||||
// func init() {
|
||||
// const prefix = "types.containerd.io"
|
||||
// // register TypeUrls for commonly marshaled external types
|
||||
// major := strconv.Itoa(specs.VersionMajor)
|
||||
// typeurl.Register(&specs.Spec{}, prefix, "opencontainers/runtime-spec", major, "Spec")
|
||||
// // this function has more Register calls, which are elided.
|
||||
// }
|
||||
//
|
||||
// This registers several types under a more complex url, which ends up mapping
|
||||
// to `types.containerd.io/opencontainers/runtime-spec/1/Spec` (or some other
|
||||
// value for major).
|
||||
//
|
||||
// Once a type is registered, it can be marshaled to a proto.Any message simply
|
||||
// by calling `MarshalAny`, like this:
|
||||
//
|
||||
// foo := &Foo{Field1: "value1", Field2: "value2"}
|
||||
// anyFoo, err := typeurl.MarshalAny(foo)
|
||||
//
|
||||
// MarshalAny will resolve the correct URL for the type. If the type in
|
||||
// question implements the proto.Message interface, then it will be marshaled
|
||||
// as a proto message. Otherwise, it will be marshaled as json. This means that
|
||||
// typeurl will work on any arbitrary data, whether or not it has a proto
|
||||
// definition, as long as it can be serialized to json.
|
||||
//
|
||||
// To unmarshal, the process is simply inverse:
|
||||
//
|
||||
// iface, err := typeurl.UnmarshalAny(anyFoo)
|
||||
// foo := iface.(*Foo)
|
||||
//
|
||||
// The correct type is automatically chosen from the type registry, and the
|
||||
// returned interface can be cast straight to that type.
