⚡ Bolt: Fix task serialization in scanners for true parallelism#75
⚡ Bolt: Fix task serialization in scanners for true parallelism#75
Conversation
- Changed `CacheScanner` and `NodeModulesScanner` from `actor` to `struct` - Updated docstrings to reflect the thread-safety architecture - By avoiding actor isolation for these stateless components, their `withTaskGroup` implementations can now execute parallel filesystem scanning across multiple threads without being serialized to the actor's context.

💡 What: Refactored
CacheScannerandNodeModulesScannerfromactortostruct.🎯 Why: In Swift structured concurrency, using an
actorto manage awithTaskGroupwhere tasks invoke synchronous, blocking I/O (likeFileManageroperations) directly on the actor inadvertently serializes the tasks, preventing parallelism. Since these components are stateless and only interact with thread-safe dependencies (FileManager.default), converting them tostructallows child tasks to execute concurrently across the global thread pool, unblocking the performance bottleneck.📊 Impact: Allows actual concurrent execution for filesystem scanning. Expect significant speedups during cache and node_modules scans, especially in I/O bound situations.
🔬 Measurement: Observe the scan times for both general caches and node_modules; the time to complete should reflect concurrent execution rather than sequential processing.
(Note: Added a journal entry to
.jules/bolt.mddocumenting the learning around Swift actor serialization and sync I/O).PR created automatically by Jules for task 13518718015767671395 started by @acebytes
