Functions

func CalcTargetHashes

func CalcTargetHashes(universe []string) (map[string]uint32, error)

CalcTargetHashes returns a map of (target name) -> (target hash) for all dependencies of the named universe (such as `//...`). If the hash changes for a given target, it is assumed that the target was affected by some change.

Types

type TargetNode

type TargetNode struct {
	Hash *uint32
	Deps []*TargetNode
	*bpb.Target
}

TargetNode wraps a Target proto message with a hash code and a list of dependent TargetNodes.

func (*TargetNode) GetDeps

func (n *TargetNode) GetDeps() []string

func (*TargetNode) GetHash

func (n *TargetNode) GetHash() uint32

GetHash returns a hash for the given TargetNode. If this hash changes, it is assumed that the corresponding Target was affected by some change. Targets are affected if source file contents change, or if rules' attributes or dependent targets change. Since dependent target changes are detected by changes in their respective hashes, GetHash will call GetHash on dependencies recursively down the build graph.

func (*TargetNode) GetName

func (n *TargetNode) GetName() string

GetName fetches the target name, which is in one of a few embedded messages depending on the target type.

func (*TargetNode) String

func (n *TargetNode) String() string
