Types ¶
type BlameDistribution ¶
type BlameDistribution struct {
// Freq contains the indices of commits that are to blame for this
// Test producing the specified digest.
Freq []int `json:"freq"`
}
BlameDistribution contains the data about which commits might have introduced Untriaged digests. TODO(kjlubick): This type might not make it to the frontend at all, in which case, it should be deleted. Otherwise, perhaps we can directly return []tiling.Commit.
func (*BlameDistribution) IsEmpty ¶
func (b *BlameDistribution) IsEmpty() bool
type Blamer ¶
type Blamer interface {
// GetBlamesForTest returns the list of WeightedBlame for the given test.
GetBlamesForTest(testName types.TestName) []WeightedBlame
// GetBlame returns the indices of the provided list of commits that likely
// caused the given test name/digest pair. If the result is empty we are not
// able to determine blame, because the test name/digest appeared prior
// to the current tile.
GetBlame(testName types.TestName, digest types.Digest, commits []tiling.Commit) BlameDistribution
}
Blamer provides the results of blame calculations from a given tile and set of expectations. Specifically, blame is trying to identify who is responsible for Untriaged digests showing up (it essentially ignores positive/negative digests). A Blamer should be immutable after creation.
type BlamerImpl ¶
type BlamerImpl struct {
// contains filtered or unexported fields
}
BlamerImpl implements the Blamer interface.
func New ¶
func New(tile *tiling.Tile, exp expectations.ReadOnly) (*BlamerImpl, error)
New returns a new Blamer instance and error. The error is not nil if the first run of calculating the blame lists failed.
func (*BlamerImpl) GetBlame ¶
func (b *BlamerImpl) GetBlame(testName types.TestName, digest types.Digest, commits []tiling.Commit) BlameDistribution
GetBlame fulfills the Blamer interface.
func (*BlamerImpl) GetBlamesForTest ¶
func (b *BlamerImpl) GetBlamesForTest(testName types.TestName) []WeightedBlame
GetBlamesForTest fulfills the Blamer interface.
type WeightedBlame ¶
WeightedBlame combines an authors name with a probability that they are on a blamelist. This is aggregated over the digests of a test.
type WeightedBlameSlice ¶
type WeightedBlameSlice []WeightedBlame
Sorting wrapper around WeightedBlame.
func (WeightedBlameSlice) Len ¶
func (w WeightedBlameSlice) Len() int
func (WeightedBlameSlice) Less ¶
func (w WeightedBlameSlice) Less(i, j int) bool
func (WeightedBlameSlice) Swap ¶
func (w WeightedBlameSlice) Swap(i, j int)
