Types ¶
type Analyzer ¶
type Analyzer struct {
// contains filtered or unexported fields
}
Analyzer computes impact radius over the graph. @intent estimate which nodes may be affected by a change
func New ¶
func New(store EdgeReader) *Analyzer
New creates an impact analyzer. @intent construct a blast-radius analyzer around a graph reader
func (*Analyzer) ImpactRadius ¶
ImpactRadius performs BFS traversal to find all nodes within the given depth. Used by MCP get_impact_radius tool and pre-merge check prompt.
@param nodeID the starting node for blast-radius analysis @param depth BFS traversal depth limit @return all nodes reachable within depth hops @intent identify blast radius of code changes for risk assessment @domainRule traverses both outgoing and incoming edges bidirectionally @see changes.Service.AnalyzePage
func (*Analyzer) ImpactRadiusBounded ¶
func (a *Analyzer) ImpactRadiusBounded(ctx context.Context, nodeID uint, depth int, opts RadiusOptions) (*RadiusResult, error)
ImpactRadiusBounded performs the bidirectional BFS that backs ImpactRadius with explicit caps. @intent expose a limit-aware blast radius traversal for cost-sensitive callers @param nodeID starting node for the BFS @param depth maximum BFS hop count (further capped by opts.MaxDepth) @param opts traversal limits applied during BFS @return RadiusResult with visited nodes and truncation metadata @domainRule traverses outgoing and incoming edges in lock step at each depth @ensures Truncated is true when MaxNodes stopped traversal before adding another node
type EdgeReader ¶
type EdgeReader interface {
GetEdgesFrom(ctx context.Context, nodeID uint) ([]graph.Edge, error)
GetEdgesFromNodes(ctx context.Context, nodeIDs []uint) ([]graph.Edge, error)
GetEdgesTo(ctx context.Context, nodeID uint) ([]graph.Edge, error)
GetEdgesToNodes(ctx context.Context, nodeIDs []uint) ([]graph.Edge, error)
GetNodeByID(ctx context.Context, id uint) (*graph.Node, error)
GetNodesByIDs(ctx context.Context, ids []uint) ([]graph.Node, error)
}
EdgeReader exposes graph queries required for impact analysis. @intent abstract bidirectional edge and node lookups for blast-radius traversal
type RadiusOptions ¶
RadiusOptions caps how far ImpactRadiusBounded is allowed to expand. @intent let callers limit BFS depth and visited node count for safety
