Functions

func AssertedSnapID

func AssertedSnapID(snapName string) string

func MakeSnapFileAndDir

func MakeSnapFileAndDir(c *check.C, snapYamlContent string, files [][]string, si *snap.SideInfo) *snap.Info

MakeSnapFileWithDir makes a squashfs snap file and a directory under /snaps/<snap>/<rev> with the given contents. It's a combined effect of MakeTestSnapInfoWithFiles and MockSnapWithFiles.

func MakeTestSnapInfoWithFiles

func MakeTestSnapInfoWithFiles(c *check.C, snapYamlContent string, files [][]string, si *snap.SideInfo) (snapFilePath string, info *snap.Info)

MakeTestSnapInfoWithFiles makes a squashfs snap file with the given snap.yaml content and optional extra files specified as pairs of relative file path and it's contents, and returns the path to the snap file and a suitable snap.Info for the snap

func MakeTestSnapWithFiles

func MakeTestSnapWithFiles(c *check.C, snapYamlContent string, files [][]string) (snapFilePath string)

MakeTestSnapWithFiles makes a squashfs snap file with the given snap.yaml content and optional extras files specified as pairs of relative file path and its content.

func MockContainer

func MockContainer(c *check.C, files [][]string) snap.Container

MockContainer returns a mock snap.Container with the given content. If files is empty it still produces a minimal container that passes ValidateContainer: / and /meta exist and are 0755, and /meta/snap.yaml is a regular world-readable file.

func MockInfo

func MockInfo(c *check.C, yamlText string, sideInfo *snap.SideInfo) *snap.Info

MockInfo parses the given snap.yaml text and returns a validated snap.Info object including the optional SideInfo.

The result is just kept in memory, there is nothing kept on disk. If that is desired please use MockSnap instead.

func MockInvalidInfo

func MockInvalidInfo(c *check.C, yamlText string, sideInfo *snap.SideInfo) *snap.Info

MockInvalidInfo parses the given snap.yaml text and returns the snap.Info object including the optional SideInfo.

The result is just kept in memory, there is nothing kept on disk. If that is desired please use MockSnap instead.

func MockSnap

func MockSnap(c *check.C, yamlText string, sideInfo *snap.SideInfo) *snap.Info

MockSnap puts a snap.yaml file on disk so to mock an installed snap, based on the provided arguments.

The caller is responsible for mocking root directory with dirs.SetRootDir() and for altering the overlord state if required.

func MockSnapCurrent

func MockSnapCurrent(c *check.C, yamlText string, sideInfo *snap.SideInfo) *snap.Info

MockSnapCurrent does the same as MockSnap but additionally creates the 'current' symlink.

The caller is responsible for mocking root directory with dirs.SetRootDir() and for altering the overlord state if required.

func MockSnapInstance

func MockSnapInstance(c *check.C, instanceName, yamlText string, sideInfo *snap.SideInfo) *snap.Info

MockSnapInstance puts a snap.yaml file on disk so to mock an installed snap instance, based on the provided arguments.

The caller is responsible for mocking root directory with dirs.SetRootDir() and for altering the overlord state if required.

func MockSnapInstanceCurrent

func MockSnapInstanceCurrent(c *check.C, instanceName, yamlText string, sideInfo *snap.SideInfo) *snap.Info

MockSnapInstanceCurrent does the same as MockSnapInstance but additionally creates the 'current' symlink.

The caller is responsible for mocking root directory with dirs.SetRootDir() and for altering the overlord state if required.

func MockSnapWithFiles

func MockSnapWithFiles(c *check.C, yamlText string, si *snap.SideInfo, files [][]string) *snap.Info

MockSnapWithFiles does the same as MockSnap, but also populates the snap directory with given content

The caller is responsible for mocking root directory with dirs.SetRootDir() and for altering the overlord state if required.

func MustParseChannel

func MustParseChannel(s string, architecture string) channel.Channel

MustParseChannel parses a string representing a store channel and includes the given architecture, if architecture is "" the system architecture is included. It panics on error.

func PopulateDir

func PopulateDir(dir string, files [][]string)

PopulateDir populates the directory with files specified as pairs of relative file path and its content. Useful to add extra files to a snap.

func RenameSlot

func RenameSlot(snapInfo *snap.Info, oldName, newName string) error

RenameSlot renames gives an existing slot a new name.

The new slot name cannot clash with an existing plug or slot and must be a valid slot name.
