@temporalio/worker 1.7.0

on Node.js NPM

Features

• 💥 [worker] The experimental Worker.runReplayHistories method, which allows efficient replay of a large number
  of workflow histories, now returns an AsyncIterableIterator (#1067)

  EXAMPLE USAGE

  const histories = client.workflow.list({ query: 'WorkflowType="MyWorkflow"' }).intoHistories({ concurrency: 10 });
  const replayResults = Worker.runReplayHistories(
    {
      workflowsPath: require.resolve('./workflows'),
      // ...
    },
    histories
  );
  for await (const result of replayResults) {
    const { workflowId, runId, error } = result;
    // error is either undefined, a ReplayError, or a DeterminismViolationError
  }

• 💥 [worker] WorkerOptions.shutdownGraceTime no longer forcefully shuts the worker down. Now, when shutdownGraceTime passes, the worker just sends Cancellation to running Activities.
  Set WorkerOptions.shutdownForceTime to force shutdown. (#1072)

• 💥 [testing] Use Temporal CLI to power local test environment (#1077)

Bug Fixes

• Fail Workflow on WorkflowExecutionAlreadyStartedError (#1068)

• [create-project] While fixing dependencies on a newly instantiated project, we now recursively search for
  package.json and tsconfig.json (#1089 thanks to @jhubbardsf 🙏)

• [create-project] Remove the .post-create file (if it exists), before committing to git (#1018)

• 💥 Completetly removed support for Node versions <= 14.17. Lot of our dependencies were already
  requiring Node 14.18+ anyway. (#1070)

• Load package abort-controller as a polyfill rather than a complete substitution.
  This will ensure using native implementation of that class in Node 16+ (#1070)

  💥 This change might cause TypeScript to warn about incompatible types when working with libraries that are using
  custom type definitions for the AbortSignal interface.

  import type { AbortSignal as FetchAbortSignal } from 'node-fetch/externals';
  // ...
  const response = await fetch(url, { signal: Context.current().cancellationSignal as FetchAbortSignal });

• [client] Get rid of experimental AsyncLocalStorage.enterWith call (#1080)

• [core] Fix slot metrics appearing to be off-by-one because of reservation (#479)

• [core] Fix misnamed metric workflow_task_execution_failed (#481)

• [core] Added an internal patching mechanism for adjusting SDK behavior based on what version of the SDK has previously processed the workflow. Note that this new mechanism requires server Temporal 1.20.0 or above. Any change that depends on such an internal patch will not be effective with older servers. (#482)

• 💥 [core] Make activity (and child workflow) type / id mismatches will results in a non-deterministic change. That means that renaming an activity or a child workflow will now require a patch. Note that this change has been gated with an internal patch to avoid suddently failing with nondeterminism errors on older activity rename (see details above) (#475, #482)

• [core] Auto-fail new workflow tasks which encounter a problem upon their application, but before any activation has been issued to lang. This may fix some scenarios where previously a WFT would simply time out. (#482)

Documentation

• Add install protocal buffers step to CONTRIBUTING.md doc (#1086, thanks to @jhubbardsf 🙏)
