Functions

func FetchAndCheckSnapAssertions

func FetchAndCheckSnapAssertions(snapPath string, info *snap.Info, f asserts.Fetcher, db asserts.RODatabase) (*asserts.SnapDeclaration, error)

FetchAndCheckSnapAssertions fetches and cross checks the snap assertions matching the given snap file using the provided asserts.Fetcher and assertion database.

func MockTrusted

func MockTrusted(mockTrusted []asserts.Assertion) (restore func())

func Prepare

func Prepare(opts *Options) error

Types

type DownloadOptions

type DownloadOptions struct {
	Revision  snap.Revision
	TargetDir string
	Channel   string
	CohortKey string
	Basename  string

	LeavePartialOnError bool
}

DownloadOptions carries options for downloading snaps plus assertions.

func (*DownloadOptions) String

func (opts *DownloadOptions) String() string

type Options

type Options struct {
	Classic         bool
	Snaps           []string
	RootDir         string
	Channel         string
	SnapChannels    map[string]string
	ModelFile       string
	GadgetUnpackDir string

	// Architecture to use if none is specified by the model,
	// useful only for classic mode. If set must match the model otherwise.
	Architecture string
}

type Store

type Store interface {
	SnapAction(context.Context, []*store.CurrentSnap, []*store.SnapAction, *auth.UserState, *store.RefreshOptions) ([]*snap.Info, error)
	Download(ctx context.Context, name, targetFn string, downloadInfo *snap.DownloadInfo, pbar progress.Meter, user *auth.UserState, dlOpts *store.DownloadOptions) error

	Assertion(assertType *asserts.AssertionType, primaryKey []string, user *auth.UserState) (asserts.Assertion, error)
}

A Store can find metadata on snaps, download snaps and fetch assertions.

type ToolingStore

type ToolingStore struct {
	// contains filtered or unexported fields
}

ToolingStore wraps access to the store for tools.

func NewToolingStore

func NewToolingStore() (*ToolingStore, error)

func NewToolingStoreFromModel

func NewToolingStoreFromModel(model *asserts.Model, fallbackArchitecture string) (*ToolingStore, error)

func (*ToolingStore) AssertionFetcher

func (tsto *ToolingStore) AssertionFetcher(db *asserts.Database, save func(asserts.Assertion) error) asserts.Fetcher

AssertionFetcher creates an asserts.Fetcher for assertions against the given store using dlOpts for authorization, the fetcher will add assertions in the given database and after that also call save for each of them.

func (*ToolingStore) DownloadSnap

func (tsto *ToolingStore) DownloadSnap(name string, opts DownloadOptions) (targetFn string, info *snap.Info, err error)

DownloadSnap downloads the snap with the given name and optionally revision using the provided store and options. It returns the final full path of the snap inside the opts.TargetDir and a snap.Info for the snap.

func (*ToolingStore) Find

func (tsto *ToolingStore) Find(at *asserts.AssertionType, headers map[string]string) (asserts.Assertion, error)

Find provides the snapsserts.Finder interface for snapasserts.DerviceSideInfo
