The model works +// by building up sets of changes with parent-child relationships. +// +// A snapshot represents a filesystem state. Every snapshot has a parent, where +// the empty parent is represented by the empty string. A diff can be taken +// between a parent and its snapshot to generate a classic layer. +// +// An active snapshot is created by calling `Prepare`. After mounting, changes +// can be made to the snapshot. The act of committing creates a committed +// snapshot. The committed snapshot will get the parent of active snapshot. The +// committed snapshot can then be used as a parent. Active snapshots can never +// act as a parent. +// +// Snapshots are best understood by their lifecycle. Active snapshots are +// always created with Prepare or View. Committed snapshots are always created +// with Commit. Active snapshots never become committed snapshots and vice +// versa. All snapshots may be removed. +// +// For consistency, we define the following terms to be used throughout this +// interface for snapshotter implementations: +// +// `ctx` - refers to a context.Context +// `key` - refers to an active snapshot +// `name` - refers to a committed snapshot +// `parent` - refers to the parent in relation +// +// Most methods take various combinations of these identifiers. Typically, +// `name` and `parent` will be used in cases where a method *only* takes +// committed snapshots. `key` will be used to refer to active snapshots in most +// cases, except where noted. All variables used to access snapshots use the +// same key space. 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 "": +// +// mounts, err := snapshotter.Prepare(ctx, key, "") +// 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: +// +// if err := snapshotter.Commit(ctx, digest.String(), key); err != nil { ... } +// +// Now, we have a layer in the Snapshotter that can be accessed with the digest +// provided during commit. Once you have committed the snapshot, the active +// snapshot can be removed with the following: +// +// snapshotter.Remove(ctx, key) +// +// 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) +// +// 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. If +// one would like to create a new image from the filesystem, Manager.Commit is +// called: +// +// if err := snapshotter.Commit(ctx, newImageSnapshot, containerKey); err != nil { ... } +// +// Alternatively, for most container runs, Snapshotter.Remove will be called to +// signal the Snapshotter to abandon the changes. +type Snapshotter interface { + // Stat returns the info for an active or committed snapshot by name or + // key. + // + // Should be used for parent resolution, existence checks and to discern + // the kind of snapshot. + Stat(ctx context.Context, key string) (Info, error) + + // Update updates the info for a snapshot. + // + // Only mutable properties of a snapshot may be updated. + Update(ctx context.Context, info Info, fieldpaths ...string) (Info, error) + + // Usage returns the resource usage of an active or committed snapshot + // excluding the usage of parent snapshots. + // + // The running time of this call for active snapshots is dependent on + // implementation, but may be proportional to the size of the resource. + // Callers should take this into consideration.

It is used by +// [gRPC](https://github.com/grpc). 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.

Since CLI plugins follow the behaviour of the CLI here it is necessary to prepend "Error: " to some messages. I've only done exactly those necessary to pass the e2e tests, a fuller audit is very likely required.
