taskpool-dependency-analysis

What problem does it solve?

It diagnoses and helps resolve static ArkTS taskpool dependency bugs where dependent tasks never execute due to incorrect dependency graphs, missing notifications, illegal addDependency/removeDependency usage, or broken cancel propagation.

Core Features & Use Cases

• Dependency graph reconstruction & cycle detection: Builds a directed dependency graph from addDependency/removeDependency and highlights circular edges (e.g., 10200026).
• Hang root-cause tracing: Traces the prerequisite finish → notifyDependencies → dependency counters → pending activation path to find why a dependent never wakes.
• Error-code-driven remediation: Identifies illegal task-type edge rules and missing/nonexistent dependency operations (e.g., 10200027, 10200070, 10200113), and recommends structural fixes.
• Cancel propagation validation: Verifies that cancellation correctly propagates through dependent chains.
