β οΈ Risk Factors
Potential risk factors associated with this change include:
β’ Incomplete or Deadlocked Shutdown: Issues in the new `cancel`/`done` channel architecture could prevent the generator goroutine from terminating correctly, potentially causing hangs or deadlocks during node shutdown.
β’ Unintended Database Access: Despite the fix, subtle bugs in the new concurrency primitives might still allow the generator to access the database after it has been closed, reintroducing the original race condition or similar issues.
β’ Performance Overhead during Shutdown: The blocking nature of `stopGeneration()`, which waits for the generator goroutine to fully exit, could introduce unexpected delays if the goroutine's termination process becomes prolonged.
