Constants

View Source 
const (
	ClusterMemberStateCreated = 0
	ClusterMemberStatePending = 1
)

Numeric type codes identifying different cluster member states.

View Source 
const (
	RaftVoter   = client.Voter
	RaftStandBy = client.StandBy

View Source 
const (
	StoragePoolVolumeTypeContainer = iota
	StoragePoolVolumeTypeImage
	StoragePoolVolumeTypeCustom
	StoragePoolVolumeTypeVM
)

XXX: this was extracted from lxd/storage_volume_utils.go, we find a way to 

factor it independently from both the db and main packages.
View Source 
const (
	StoragePoolVolumeTypeNameContainer string = "container"
	StoragePoolVolumeTypeNameVM        string = "virtual-machine"
	StoragePoolVolumeTypeNameImage     string = "image"
	StoragePoolVolumeTypeNameCustom    string = "custom"
)

Leave the string type in here! This guarantees that go treats this is as a typed string constant. Removing it causes go to treat these as untyped string constants which is not what we want.

View Source 
const (
	StoragePoolVolumeContentTypeFS = iota
	StoragePoolVolumeContentTypeBlock
)

Content types.

View Source 
const (
	StoragePoolVolumeContentTypeNameFS    string = "filesystem"

Variables

View Source 
var (
	// ErrAlreadyDefined hapens when the given entry already exists,
	// for example a container.
	ErrAlreadyDefined = fmt.Errorf("The record already exists")

	// ErrNoSuchObject is in the case of joins (and probably other) queries,
	// we don't get back sql.ErrNoRows when no rows are returned, even though we do
	// on selects without joins. Instead, you can use this error to
	// propagate up and generate proper 404s to the client when something
	// isn't found so we don't abuse sql.ErrNoRows any more than we
	// already do.
	ErrNoSuchObject = fmt.Errorf("No such object")

	// ErrNoClusterMember is used to indicate no cluster member has been found for a resource.
	ErrNoClusterMember = fmt.Errorf("No cluster member found")
)
View Source 
var ClusterRoles = map[int]ClusterRole{}

ClusterRoles maps role ids into human-readable names.
