// Manages CIPD packages and their associated metadata.
//
// A package is a named collection of one or more versions of a group of files.
// A package should typically be used for a single software component or
// dataset, not a conglomeration. A package instance is a concrete incarnation
// of a such version: it is a real file, and it is identified by its SHA256 (or
// SHA1 for older packages) digest, represented by ObjectRef proto in the
// protocol.
//
// A particular serialization of ObjectRef proto into a string is referred to
// as "instance ID" and it is used to identify package instances (mostly in
// the interface exposed by the CIPD command line client, but also in
// ResolveVersion RPC):
// * For legacy reasons SHA1 digests are encoded with lowercase hex encoding,
// which always results in 40 char ASCII strings).
// * Other digests are encoded using base64(digest + []byte{ref.HashAlgo}),
// where 'base64' is URL-safe and unpadded and '+' is concatenation.
// For SHA256 digests this results in 44 char ASCII strings that end with C.
//
// Instance files themselves are zip archives with some additional metadata.
// They are produced and consumed by cipd CLI client, and the backend mostly
// doesn't care about their internal structure.
//
// Package names look like rootless file system paths (e.g. "a/b/c"). The
// identifier of a package is always the full path. There's no notion of
// "relative paths", or "..", or any other similar constructs. The name of the
// last path component has no intrinsic significance either, though it is often
// used to denote a platform the package is intended for. For example
// "infra/tools/cipd/linux-amd64" package is intended for Linux running on amd64
// architecture. This is just a convention, and it is not enforced nor
// understood by the backend.
//
// Each element of the package namespace (known as "package path prefix" or just
// "prefix") can have some metadata attached to it. Currently it includes only
// an access control list (ACL) that specifies what roles are granted to what
// users for the given prefix and all packages underneath it.
//
// For example, granting READER role to user@example.com in ACL associated with
// prefix "a/b/c" gives user@example.com permission to read all package
// instances of "a/b/c" and any packages below it (e.g. "a/b/c/d"). See Role
// enum for list of roles.
//
// There's no finer permission granularity inside the package itself, e.g. it is
// not possible to allow to read some particular package instance, without
// allowing to read all instances of the package.

//
// It understands and expands roles inheritance, e.g. if the caller is an

// will be:
// * {packages: ["a/b"], prefixes: ["a/c"]} if listing non-recursively.
// * {packages: ["a/b", "a/c/d", "a/c/e/f"], prefixes: ["a/c", "a/c/e"]} if
// listing recursively.
//
// Returns only packages and prefixes visible to the caller. This applies even
// when listing a prefix the caller has no direct read access to. For example,
// recursively listing the root prefix will return all packages the caller has
// read access to (no matter when in the hierarchy they are located), even if
// the caller has no READER permission in the root. It works as if the caller
// can freely browse the repository that contains only the packages they can

// A ref is a mutable named pointer to some existing package instance that

//
// Refs are namespaced to some particular package. E.g. "latest" ref in

rpc ListRefs(ListRefsRequest) returns (ListRefsResponse);
// Attaches one or more tags to an instance.
//
// Silently skips already attached tags.
//
// Tags are "key:value" pairs associated with a concrete package instance.
// They can be used for querying registered instances and for version
// resolution: if a tag is attached to one and only one instance of a package,
// the tag uniquely identifies this instance and such tag can be used as an
// alias of the instance ID.
//
// Tags generally should be assumed globally namespaced (e.g. it makes sense
// to query for all registered instances with a given tag, across all
// packages), and they don't have to be unique: same tag may be attached to
// multiple instances (of the same or different packages).
//
// Additionally, tags (unlike refs) are intended to be mostly static, since
// they usually relate to some properties of package instances, which are
// static entities. This is particularity important for tags used for version
// resolution.
//
// Attaching a tag to an instance generally makes the instance "discoverable".
// For that reason tags can be attached only to instances that successfully
// passed all post-registration processing.
//

// INVALID_ARGUMENT if the request is malformed.
// NOT_FOUND if the package or the instance doesn't exist.

// static (and thus not detachable).
//
// It is occasionally useful for fixing screw ups though. For that reason,
// DetachTags is allowed only by OWNERS of a prefix (not WRITERS, like
// AttachTags).

// Returns:

// A single key can have multiple different values associated with it.
// Completely identical key-value pairs are deduplicated: attaching already
// attached metadata is a noop. Thus all metadata of an instance is a
// multimap, where a key maps to a set of unique values.
//
// A metadata entry is identified by its fingerprint: a hash of concatenated
// key and value (see InstanceMetadata message for details). It can be used,
// for example, to point to an entry to detach in DetachMetadata.
