For example, an active snapshot may not share the same key -// with a committed snapshot. -// -// We cover several examples below to demonstrate the utility of a snapshot -// snapshotter. -// -// Importing a Layer -// -// To import a layer, we simply have the Snapshotter provide a list of -// mounts to be applied such that our dst will capture a changeset. We start -// out by getting a path to the layer tar file and creating a temp location to -// unpack it to: -// -// layerPath, tmpDir := getLayerPath(), mkTmpDir() // just a path to layer tar file. -// -// We start by using a Snapshotter to Prepare a new snapshot transaction, using a -// key and descending from the empty parent "". To prevent our layer from being -// garbage collected during unpacking, we add the `containerd.io/gc.root` label: -// -// noGcOpt := snapshots.WithLabels(map[string]string{ -// "containerd.io/gc.root": time.Now().UTC().Format(time.RFC3339), -// }) -// mounts, err := snapshotter.Prepare(ctx, key, "", noGcOpt) -// if err != nil { ... } -// -// We get back a list of mounts from Snapshotter.Prepare, with the key identifying -// the active snapshot. Mount this to the temporary location with the -// following: -// -// if err := mount.All(mounts, tmpDir); err != nil { ... } -// -// Once the mounts are performed, our temporary location is ready to capture -// a diff. In practice, this works similar to a filesystem transaction. The -// next step is to unpack the layer. We have a special function unpackLayer -// that applies the contents of the layer to target location and calculates the -// DiffID of the unpacked layer (this is a requirement for docker -// implementation): -// -// layer, err := os.Open(layerPath) -// if err != nil { ... } -// digest, err := unpackLayer(tmpLocation, layer) // unpack into layer location -// if err != nil { ... } -// -// When the above completes, we should have a filesystem the represents the -// contents of the layer. Careful implementations should verify that digest -// matches the expected DiffID. When completed, we unmount the mounts: -// -// unmount(mounts) // optional, for now -// -// Now that we've verified and unpacked our layer, we commit the active -// snapshot to a name. For this example, we are just going to use the layer -// digest, but in practice, this will probably be the ChainID. This also removes -// the active snapshot: -// -// if err := snapshotter.Commit(ctx, digest.String(), key, noGcOpt); err != nil { ... } -// -// Now, we have a layer in the Snapshotter that can be accessed with the digest -// provided during commit. -// -// Importing the Next Layer -// -// Making a layer depend on the above is identical to the process described -// above except that the parent is provided as parent when calling -// Manager.Prepare, assuming a clean, unique key identifier: -// -// mounts, err := snapshotter.Prepare(ctx, key, parentDigest, noGcOpt) -// -// We then mount, apply and commit, as we did above. The new snapshot will be -// based on the content of the previous one. -// -// Running a Container -// -// To run a container, we simply provide Snapshotter.Prepare the committed image -// snapshot as the parent. After mounting, the prepared path can -// be used directly as the container's filesystem: -// -// mounts, err := snapshotter.Prepare(ctx, containerKey, imageRootFSChainID) -// -// The returned mounts can then be passed directly to the container runtime.

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. diff --git a/vendor/github.com/containerd/typeurl/go.mod b/vendor/github.com/containerd/typeurl/go.mod deleted file mode 100644 index cfcee31f..00000000 --- a/vendor/github.com/containerd/typeurl/go.mod +++ /dev/null @@ -1,8 +0,0 @@ -module github.com/containerd/typeurl - -go 1.13 - -require ( - github.com/gogo/protobuf v1.3.1 - github.com/pkg/errors v0.9.1 -) diff --git a/vendor/github.com/containerd/typeurl/go.sum b/vendor/github.com/containerd/typeurl/go.sum deleted file mode 100644 index 50815ccb..00000000 --- a/vendor/github.com/containerd/typeurl/go.sum +++ /dev/null @@ -1,7 +0,0 @@ -github.com/gogo/protobuf v1.3.1 h1:DqDEcV5aeaTmdFBePNpYsp3FlcVH/2ISVVM9Qf8PSls= -github.com/gogo/protobuf v1.3.1/go.mod h1:SlYgWuQ5SjCEi6WLHjHCa1yvBfUnHcTbrrZtXPKa29o= -github.com/kisielk/errcheck v1.2.0/go.mod h1:/BMXB+zMLi60iA8Vv6Ksmxu/1UDYcXs4uQLJ+jE2L00= -github.com/kisielk/gotool v1.0.0/go.mod h1:XhKaO+MFFWcvkIS/tQcRk01m1F5IRFswLeQ+oQHNcck= -github.com/pkg/errors v0.9.1 h1:FEBLx1zS214owpjy7qsBeixbURkuhQAwrK5UwLGTwt4= -github.com/pkg/errors v0.9.1/go.mod h1:bwawxfHBFNV+L2hUp1rHADufV3IMtnDRdf1r5NINEl0= -golang.org/x/tools v0.0.0-20181030221726-6c7e314b6563/go.mod h1:n7NCudcB/nEzxVGmLbDWY5pfWTLqBcC2KZ6jyYvM4mQ= diff --git a/vendor/github.com/containerd/typeurl/types.go b/vendor/github.com/containerd/typeurl/types.go deleted file mode 100644 index b70314fd..00000000 --- a/vendor/github.com/containerd/typeurl/types.go +++ /dev/null @@ -1,168 +0,0 @@ -/* - Copyright The containerd Authors. - - Licensed under the Apache License, Version 2.0 (the "License"); - you may not use this file except in compliance with the License. - You may obtain a copy of the License at - - http://www.apache.org/licenses/LICENSE-2.0 - - Unless required by applicable law or agreed to in writing, software - distributed under the License is distributed on an "AS IS" BASIS, - WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. - See the License for the specific language governing permissions and - limitations under the License. -*/ - -package typeurl - -import ( - "encoding/json" - "path" - "reflect" - "sync" - - "github.com/gogo/protobuf/proto" - "github.com/gogo/protobuf/types" - "github.com/pkg/errors" -) - -var ( - mu sync.Mutex - registry = make(map[reflect.Type]string) -) - -var ErrNotFound = errors.New("not found") - -// Register a type with a base URL for JSON marshaling.

This package is -most of the same code with slightly updated interfaces. Much of the internals -have been made available. - -## Usage - -The `events` package centers around a `Sink` type. Events are written with -calls to `Sink.Write(event Event)`. Sinks can be wired up in various -configurations to achieve interesting behavior. - -The canonical example is that employed by the -[docker/distribution/notifications](https://godoc.org/github.com/docker/distribution/notifications) -package. Let's say we have a type `httpSink` where we'd like to queue -notifications. As a rule, it should send a single http request and return an -error if it fails: - -```go -func (h *httpSink) Write(event Event) error { - p, err := json.Marshal(event) - if err != nil { - return err - } - body := bytes.NewReader(p) - resp, err := h.client.Post(h.url, "application/json", body) - if err != nil { - return err - } - defer resp.Body.Close() - - if resp.Status != 200 { - return errors.New("unexpected status") - } - - return nil -} - -// implement (*httpSink).Close() -``` - -With just that, we can start using components from this package. One can call -`(*httpSink).Write` to send events as the body of a post request to a -configured URL. - -### Retries - -HTTP can be unreliable. The first feature we'd like is to have some retry: - -```go -hs := newHTTPSink(/*...*/) -retry := NewRetryingSink(hs, NewBreaker(5, time.Second)) -``` - -We now have a sink that will retry events against the `httpSink` until they -succeed. The retry will backoff for one second after 5 consecutive failures -using the breaker strategy. - -### Queues - -This isn't quite enough. We we want a sink that doesn't block while we are -waiting for events to be sent. Let's add a `Queue`: - -```go -queue := NewQueue(retry) -``` - -Now, we have an unbounded queue that will work through all events sent with -`(*Queue).Write`. Events can be added asynchronously to the queue without -blocking the current execution path. This is ideal for use in an http request. - -### Broadcast - -It usually turns out that you want to send to more than one listener. We can -use `Broadcaster` to support this: - -```go -var broadcast = NewBroadcaster() // make it available somewhere in your application. -broadcast.Add(queue) // add your queue! -broadcast.Add(queue2) // and another! -``` - -With the above, we can now call `broadcast.Write` in our http handlers and have -all the events distributed to each queue. Because the events are queued, not -listener blocks another. - -### Extending - -For the most part, the above is sufficient for a lot of applications. However, -extending the above functionality can be done implementing your own `Sink`. The -behavior and semantics of the sink can be completely dependent on the -application requirements. The interface is provided below for reference: - -```go -type Sink { - Write(Event) error - Close() error -} -``` - -Application behavior can be controlled by how `Write` behaves. The examples -above are designed to queue the message and return as quickly as possible. -Other implementations may block until the event is committed to durable -storage. - -## Copyright and license - -Copyright © 2016 Docker, Inc. go-events is licensed under the Apache License, -Version 2.0.

The error model is designed to be: -// -// - Simple to use and understand for most users -// - Flexible enough to meet unexpected needs -// -// # Overview -// -// The `Status` message contains three pieces of data: error code, error -// message, and error details. The error code should be an enum value of -// [google.rpc.Code][google.rpc.Code], but it may accept additional error codes -// if needed. The error message should be a developer-facing English message -// that helps developers *understand* and *resolve* the error. If a localized -// user-facing error message is needed, put the localized message in the error -// details or localize it in the client. The optional error details may contain -// arbitrary information about the error. There is a predefined set of error -// detail types in the package `google.rpc` that can be used for common error -// conditions. -// -// # Language mapping -// -// The `Status` message is the logical representation of the error model, but it -// is not necessarily the actual wire format. When the `Status` message is -// exposed in different client libraries and different wire protocols, it can be -// mapped differently. For example, it will likely be mapped to some exceptions -// in Java, but more likely mapped to some error codes in C. -// -// # Other uses -// -// The error model and the `Status` message can be used in a variety of -// environments, either with or without APIs, to provide a -// consistent developer experience across different environments. -// -// Example uses of this error model include: -// -// - Partial errors. If a service needs to return partial errors to the client, -// it may embed the `Status` in the normal response to indicate the partial -// errors. -// -// - Workflow errors. A typical workflow has multiple steps. Each step may -// have a `Status` message for error reporting. -// -// - Batch operations. If a client uses batch request and batch response, the -// `Status` message should be used directly inside batch response, one for -// each error sub-response. -// -// - Asynchronous operations. If an API call embeds asynchronous operation -// results in its response, the status of those operations should be -// represented directly using the `Status` message. -// -// - Logging. If some API errors are stored in logs, the message `Status` could -// be used directly after any stripping needed for security/privacy reasons. -type Status struct { - // The status code, which should be an enum value of - // [google.rpc.Code][google.rpc.Code]. - Code int32 `protobuf:"varint,1,opt,name=code,proto3" json:"code,omitempty"` - // A developer-facing error message, which should be in English.

The error code should be an enum value of -// [google.rpc.Code][google.rpc.Code], but it may accept additional error codes -// if needed. The error message should be a developer-facing English message -// that helps developers *understand* and *resolve* the error. If a localized -// user-facing error message is needed, put the localized message in the error -// details or localize it in the client. The optional error details may contain -// arbitrary information about the error. There is a predefined set of error -// detail types in the package `google.rpc` that can be used for common error -// conditions. -// -// # Language mapping -// -// The `Status` message is the logical representation of the error model, but it -// is not necessarily the actual wire format. When the `Status` message is -// exposed in different client libraries and different wire protocols, it can be -// mapped differently. For example, it will likely be mapped to some exceptions -// in Java, but more likely mapped to some error codes in C. -// -// # Other uses -// -// The error model and the `Status` message can be used in a variety of -// environments, either with or without APIs, to provide a -// consistent developer experience across different environments. -// -// Example uses of this error model include: -// -// - Partial errors. If a service needs to return partial errors to the client, -// it may embed the `Status` in the normal response to indicate the partial -// errors. -// -// - Workflow errors. A typical workflow has multiple steps. Each step may -// have a `Status` message for error reporting. -// -// - Batch operations. If a client uses batch request and batch response, the -// `Status` message should be used directly inside batch response, one for -// each error sub-response. -// -// - Asynchronous operations. If an API call embeds asynchronous operation -// results in its response, the status of those operations should be -// represented directly using the `Status` message. -// -// - Logging. If some API errors are stored in logs, the message `Status` could -// be used directly after any stripping needed for security/privacy reasons. -message Status { - // The status code, which should be an enum value of - // [google.rpc.Code][google.rpc.Code]. - int32 code = 1; - - // A developer-facing error message, which should be in English.

In case of a REST custom method, -// other definitions may be used. Where the mask applies will be -// clearly documented together with its declaration in the API. In -// any case, the effect on the returned resource/resources is required -// behavior for APIs. -// -// # Field Masks in Update Operations -// -// A field mask in update operations specifies which fields of the -// targeted resource are going to be updated. The API is required -// to only change the values of the fields as specified in the mask -// and leave the others untouched. If a resource is passed in to -// describe the updated values, the API ignores the values of all -// fields not covered by the mask. -// -// If a repeated field is specified for an update operation, new values will -// be appended to the existing repeated field in the target resource.

If this is unwanted -// behavior, a specific service may require a client to always specify -// a field mask, producing an error if not. -// -// As with get operations, the location of the resource which -// describes the updated values in the request message depends on the -// operation kind. In any case, the effect of the field mask is -// required to be honored by the API. -// -// ## Considerations for HTTP REST -// -// The HTTP kind of an update operation which uses a field mask must -// be set to PATCH instead of PUT in order to satisfy HTTP semantics -// (PUT must only be used for full updates). -// -// # JSON Encoding of Field Masks -// -// In JSON, a field mask is encoded as a single string where paths are -// separated by a comma.

Here are code snippets -demonstrating some important use cases. - -#### Singleton initialization - -The simplest starting point is `./default_tracer.go`. As early as possible, call - -```go - import "github.com/opentracing/opentracing-go" - import ".../some_tracing_impl" - - func main() { - opentracing.SetGlobalTracer( - // tracing impl specific: - some_tracing_impl.New(...), - ) - ... - } -``` - -#### Non-Singleton initialization - -If you prefer direct control to singletons, manage ownership of the -`opentracing.Tracer` implementation explicitly. - -#### Creating a Span given an existing Go `context.Context` - -If you use `context.Context` in your application, OpenTracing's Go library will -happily rely on it for `Span` propagation. To start a new (blocking child) -`Span`, you can use `StartSpanFromContext`. - -```go - func xyz(ctx context.Context, ...) { - ... - span, ctx := opentracing.StartSpanFromContext(ctx, "operation_name") - defer span.Finish() - span.LogFields( - log.String("event", "soft error"), - log.String("type", "cache timeout"), - log.Int("waited.millis", 1500)) - ... - } -``` - -#### Starting an empty trace by creating a "root span" - -It's always possible to create a "root" `Span` with no parent or other causal -reference. - -```go - func xyz() { - ... - sp := opentracing.StartSpan("operation_name") - defer sp.Finish() - ... - } -``` - -#### Creating a (child) Span given an existing (parent) Span - -```go - func xyz(parentSpan opentracing.Span, ...) { - ... - sp := opentracing.StartSpan( - "operation_name", - opentracing.ChildOf(parentSpan.Context())) - defer sp.Finish() - ... - } -``` - -#### Serializing to the wire - -```go - func makeSomeRequest(ctx context.Context) ... { - if span := opentracing.SpanFromContext(ctx); span != nil { - httpClient := &http.Client{} - httpReq, _ := http.NewRequest("GET", "http://myservice/", nil) - - // Transmit the span's TraceContext as HTTP headers on our - // outbound request. - opentracing.GlobalTracer().Inject( - span.Context(), - opentracing.HTTPHeaders, - opentracing.HTTPHeadersCarrier(httpReq.Header)) - - resp, err := httpClient.Do(httpReq) - ... - } - ... - } -``` - -#### Deserializing from the wire - -```go - http.HandleFunc("/", func(w http.ResponseWriter, req *http.Request) { - var serverSpan opentracing.Span - appSpecificOperationName := ... - wireContext, err := opentracing.GlobalTracer().Extract( - opentracing.HTTPHeaders, - opentracing.HTTPHeadersCarrier(req.Header)) - if err != nil { - // Optionally record something about err here - } - - // Create the span referring to the RPC client if available. - // If wireContext == nil, a root span will be created. - serverSpan = opentracing.StartSpan( - appSpecificOperationName, - ext.RPCServerOption(wireContext)) - - defer serverSpan.Finish() - - ctx := opentracing.ContextWithSpan(context.Background(), serverSpan) - ... - } -``` - -#### Conditionally capture a field using `log.Noop` - -In some situations, you may want to dynamically decide whether or not -to log a field.

In particular, see `basictracer.New(...)`. - -## API compatibility - -For the time being, "mild" backwards-incompatible changes may be made without changing the major version number.
