Walkthrough

The changes update the job handling and scheduling logic within several services. New job handlers for expiration and delayed runs are added to the common worker. Existing calls to dequeue a run have been replaced by an acknowledgment method. Additionally, the static methods for enqueuing and rescheduling delayed runs are introduced and refactored. The modifications also simplify method signatures, remove unnecessary transaction parameters, and adjust retry configurations.

Changes

File(s) Change Summary
apps/.../commonWorker.server.ts Added new job handlers "v3.expireRun" and "v3.enqueueDelayedRun" with updated retry configuration (max 6 attempts) and removed return statements from existing job handlers.
apps/.../services/{createTaskRunAttempt, expireEnqueuedRun, finalizeTaskRun}.server.ts Replaced calls to dequeue with ack (and removed tx parameter where applicable), reorganized imports, and updated the method signatures in expiration handling.
apps/.../services/enqueueDelayedRun.server.ts Introduced static methods enqueue and reschedule for job scheduling; modified the call method to remove the transaction parameter and streamline enqueue logic.
apps/.../services/rescheduleTaskRun.server.ts Removed the transaction block wrapping the update operation and refactored to call EnqueueDelayedRunService.reschedule directly for handling delayed runs.
apps/.../services/triggerTask.server.ts Updated delayed run handling by replacing workerQueue.enqueue with EnqueueDelayedRunService.enqueue and simplified the call to ExpireEnqueuedRunService.enqueue by removing the transaction parameter.

Poem

Oh, how the code hops with glee,
New handlers and methods for runs set free.
I've ditched the dequeue for a friendly "ack",
Delayed runs now follow a smoother track.
With a twitch of my nose and a joyful leap,
I celebrate these changes while in my sleep.
🐇✨ Happy coding, from this rabbit so deep!

apps/webapp/app/v3/services/rescheduleTaskRun.server.ts (2)

1-4: LGTM! Import changes align with the PR objective.

The addition of EnqueueDelayedRunService import supports the migration of delay handling to the redis worker.


8-17: LGTM! Robust validation logic preserved.

The service maintains essential validation checks:

  1. Ensures task run is in "DELAYED" status
  2. Validates the delay parameter
apps/webapp/app/v3/services/expireEnqueuedRun.server.ts (2)

9-13: LGTM! The ack method is a good replacement for dequeue.

The implementation correctly acknowledges the run without redundant dequeuing, which is safer and more efficient.


15-21: LGTM! The enqueue method has been simplified.

The implementation correctly structures the job object with all necessary fields and uses a consistent ID format.

apps/webapp/app/v3/services/enqueueDelayedRun.server.ts (2)

11-18: LGTM! The enqueue method is well-implemented.

The implementation correctly structures the job object and uses a consistent ID format.


20-33: Verify the job ID format consistency.

The implementation correctly handles old job cleanup, but there's an inconsistency in the job ID format:

  • Line 25 uses: v3.enqueueDelayedRun.${runId}
  • Line 31 uses: v3.enqueueDelayed:${runId}

Consider using the same separator consistently to avoid potential issues:

-    await workerQueue.dequeue(`v3.enqueueDelayedRun.${runId}`);
+    await workerQueue.dequeue(`v3.enqueueDelayed:${runId}`);
apps/webapp/app/v3/commonWorker.server.ts (2)

99-108: LGTM! The job handlers are consistently implemented.

The implementations are simple, consistent, and correctly handle the job payloads.


57-74: Verify the higher retry limits for new jobs.

The new jobs have higher retry limits (6 attempts) compared to other jobs (3 attempts). While this might be intentional due to the critical nature of these operations, it's worth verifying.

Consider documenting the reason for higher retry limits in comments:

 "v3.expireRun": {
   schema: z.object({
     runId: z.string(),
   }),
   visibilityTimeoutMs: 60_000,
   retry: {
+    // Higher retry limit due to critical nature of run expiration
     maxAttempts: 6,
   },
 },
✅ Verification successful

Document rationale for elevated retry limits in new jobs
The configuration for v3.expireRun and v3.enqueueDelayedRun indeed sets a higher retry limit (6 attempts) compared to other jobs (typically using 3 attempts). This appears intentional—likely to accommodate the critical nature of these operations—so no functional change is required. However, adding an inline comment to document the rationale can help improve code clarity and future maintainability.

  • Location: apps/webapp/app/v3/commonWorker.server.ts (lines 57–74)

  • Observation: New jobs use maxAttempts: 6, while similar jobs in the codebase generally use a lower retry limit (3 attempts).

  • Recommendation: Add a comment explaining that the higher retry limit is intentional due to the critical nature of these new jobs, as illustrated below:

     "v3.expireRun": {
       schema: z.object({
         runId: z.string(),
       }),
       visibilityTimeoutMs: 60_000,
       retry: {
    +    // Higher retry limit due to critical nature of run expiration
         maxAttempts: 6,
       },
     },
apps/webapp/app/v3/services/createTaskRunAttempt.server.ts (1)

159-159: LGTM! The change to use ack is consistent.

The implementation correctly uses the new ack method and maintains transaction integrity.

apps/webapp/app/v3/services/finalizeTaskRun.server.ts (1)

104-104: LGTM! The change aligns with the refactor.

The change from dequeue to ack is consistent with the broader refactor to simplify the interaction with the worker queue.

apps/webapp/app/v3/services/triggerTask.server.ts (3)

31-31: LGTM! Import aligns with the refactor.

The import of EnqueueDelayedRunService is necessary for the refactor.


519-519: LGTM! The change aligns with the refactor.

The change to use EnqueueDelayedRunService.enqueue is consistent with moving run delays to redis worker.


526-526: LGTM! The change aligns with the refactor.

The removal of the transaction parameter from ExpireEnqueuedRunService.enqueue is consistent with simplifying the method signature.
