Functions ¶
func ComputeChangeFrequencies ¶
ComputeChangeFrequencies computes change frequency as touchCount/totalCommits per package.
func ComputeScores ¶
func ComputeScores( instabilities map[string]float64, changeFreqs map[string]float64, curve *CatmullRomCurve, ) map[string]PackageScore
ComputeScores computes hotspot scores for each package. hotspot = changeFreq * curve.Evaluate(instability).
Types ¶
type CatmullRomCurve ¶
type CatmullRomCurve struct {
// contains filtered or unexported fields
}
CatmullRomCurve evaluates a Catmull-Rom spline that passes through the given control points.
func DefaultCurve ¶
func DefaultCurve() *CatmullRomCurve
DefaultCurve returns a symmetric bell curve with peak at x=0.5. Control points: (0, 0.5), (0.5, 1), (1, 0.5).
func NewCatmullRomCurve ¶
func NewCatmullRomCurve(points []ControlPoint) (*CatmullRomCurve, error)
NewCatmullRomCurve creates a Catmull-Rom curve from the given control points. Points must be sorted by X. At least 2 points are required. Phantom endpoints are generated by reflecting the first/last segment.
func (*CatmullRomCurve) Evaluate ¶
func (c *CatmullRomCurve) Evaluate(xValue float64) float64
Evaluate returns the Y value of the curve at the given X. X is clamped to the range of the original control points.
type ControlPoint ¶
type ControlPoint struct {
X, Y float64
}
ControlPoint defines a point on the Catmull-Rom curve.
type PackageScore ¶
type PackageScore struct {
ChangeFreq float64 `json:"ChangeFreq"`
HotspotScore float64 `json:"HotspotScore"`
}
PackageScore holds the computed hotspot data for a single package.
