Expand description

This resolves packages from a repository.

This is intended to be implemented by package resolver components, and used by repository administration tools.

Variants§

§

Resolve

Fields

§package_url: String
§dir: ServerEnd<DirectoryMarker>

Populates or updates the cache of a package using an absolute package URL.

Ensures that a package, and any transitive subpackages, are on the local filesystem.

  • request package_url the absolute package URL for a package. The following link describes the format: https://fuchsia.dev/fuchsia-src/concepts/packages/package_url. Resource paths are not allowed.
  • request dir a request for a directory that will be resolved when the package has been successfully cached.
  • returns a resolved_context, which can be passed to ResolveWithContext, with a relative URL, to resolve a subpackage of this package.
  • error indicates failure. See ResolveError for values and error scenarios.
§

ResolveWithContext

Populates or updates the cache of a package using either an absolute or a relative package URL. If relative, the package will be resolved relative to the supplied context.

Ensures that a package is on the local filesystem.

  • request package_url the absolute or relative package URL for a package. If absolute, the context is ignored, and the behavior is identical to calling Resolve(). A relative package_url is a subpackage name.
  • request context a ResolutionContext associated with a previously resolved package, for resolving subpackages relative to that package.
  • request dir a request for a directory that will be resolved when the package has been successfully cached.
  • returns a resolved_context, which can be passed to a subsequent call to ResolveWithContext, with a relative URL, to resolve a subpackage of this package or subpackage.
  • error indicates failure. See ResolveError for values and error scenarios.
§

GetHash

Fields

§package_url: PackageUrl

Determines the hash of a package.

  • request package_url the package URL for a package.
  • response meta_far_blob_id the hash of the package.
  • error a zx_status value indicating failure. One of the following:
    • ZX_ERR_INTERNAL if the resolver encountered an otherwise unspecified error while handling the request.
    • ZX_ERR_NOT_FOUND if the package does not exist in the repository specified by package_url.
    • ZX_ERR_BAD_STATE if the resolver does not know about the repository specified by package_url.
