v1.39.0

Release Notes

• #4638 feat(api): v2 api cancel run

  Adds cancel run to the v2 rest api and cli.

  POST /api/v2/runs/{run_id}/cancel

  inngest api POST /api/v2/runs/{run_id}/cancel

• #4645 feat(api): rest v2 rerun from step

  POST /v2/runs/{run_id}/rerun

  with payload:

  {
    "fromStep": {
      "stepId": "fetch-user",
      "input": [
        {
          "userId": "user_123"
        }
      ]
    }
  }

  CLI equivalent:

  inngest api --prod rerun <run_id> \
    --from-step "step 2" \
    --input '[{"foo":"bar"}]'

Migration Notes

• #4655 refactor(queue): add shard scanner boundary

  None

  Validation

  • go test -count=1 ./pkg/execution/queue
  • go test -run '^$' ./pkg/execution/state/redis_state

• #4665 refactor(queue): add scanner runtime

  Out-of-tree queue scanner implementations must update Run(ctx, dispatch) to Run(ctx, runtime), use runtime.Dispatch to submit leased work, and may inspect runtime.WorkerSemaphore before scanning. Implementations that call DispatchFunc must handle the returned DispatchedItem; callers may ignore it, or wait on Done() with context cancellation or a timeout.

  Callers of LeaseItem must stop passing queue partitions and instead provide item metadata on LeaseItemRequest. Callers of ProcessItem must handle the new (ProcessItemResult, error) return shape.

  Validation

  • go test ./pkg/execution/queue
  • go test ./tests/execution/queue
  • make lint

• #4672 fix(executor): recover from panics in event lifecycle listeners

  Test Plan

  Added TestRunEventLifecyclesRecoversFromListenerPanic which verifies that:

  • A panicking listener is called and its panic is recovered
  • Subsequent listeners are still called despite the panic
  • Multiple invocations of runEventLifecycles work correctly even after a panic
