[0.16.4] - 2021-12-08

Bug Fixes

Update core to fix workflow semaphore not released on cache miss (#424)

Features

Default WorkflowHandle generic T param to Workflow (#419)

Miscellaneous Tasks

Add comments for unused query and signal generics (#402)
[docs] Expose worker.CoreOptions (#416)
[docs] Expose BundleOptions and remove __namedParameters (#404)
Remove proto usage from workflow runtime (#423)

This is now possible because we're using vm instead of isolated-vm.
- Greatly reduce workflow bundle size - SDK test bundle size went down from 2.77MB to 0.73MB
- Step 1 in supporting custom data converter

Testing

Ignore github actions jobs that require secrets for external committers (#414)

[0.16.3] - 2021-11-29

Bug Fixes

[workflow] Fix argument wrapping in array when signaling from Workflow (#410)

Before this fix, signal arguments sent from a workflow would be wrapped in an array, e.g:
```
await child.signal(someSignal, 1, '2');
```
Was received in the child workflow as:
```
wf.setHandler(someSignal, (num: number, str: string) => {
  console.log(num, str); // [1, '2'] undefined
});
```
[core] Upgrade Core to receive fixes to activity heartbeats (#411)
- Fix hang in case Activity completes after heartbeat response indicates Activity timed out.
- Behavior was incorrect and not inline with the other SDKs. Heartbeats are now throttled using a timer and Core does not count on user to keep sending heartbeats in order flush them out.
  
  Added 2 new WorkerOptions to control throttling:
  - maxHeartbeatThrottleInterval
  - defaultHeartbeatThrottleInterval

Miscellaneous Tasks

[docs] Explain that getHandle doesn't validate workflowId (#400)
Don't use fs-extra in create-project (#412)

Fixes issue where fs-extra is incompatible with ESM as reported on slack.

[0.16.2] - 2021-11-23 - beta

Features

[worker] Add WorkerOptions.debugMode to enable debugging Workflows (#398)

[0.16.1] - 2021-11-22 - beta-rc.1

Features

[create-project] Use chalk-template instead of chalk-cli (#396)
- Fixes issues where npx @temporalio/create fails to resolve the chalk executable

[0.16.0] - 2021-11-19 - beta-rc.0

Bug Fixes

[core] Update Core w/ specifying queue kind on polling (#389)
- Must be specified for optimization reasons on server
[core] Update Core to receive bugfixes (#391)
- Fix a situation where Core could get stuck polling if WFTs were repeatedly being failed
- Do not fail Workflow if Lang (TypeScript) cancels something that's already completed (e.g. activity, timer, child workflow)
- Fix for Core accidentally still sending commands sometimes for things that were cancelled immediately

Features

💥 [client] Make workflowId required (#387)

Also remove WorkflowClientOptions.workflowDefaults.

Reasoning:
- Workflow IDs should represent a meaningful business ID
- Workflow IDs can be used as an idempotency key when starting workflows from an external signal
- workflowDefaults were removed because their presence made taskQueue optional in WorkflowOptions, omitting it from both the defaults and options resulted in runtime errors where we could have caught those at compile time.
Migration:
```
// Before
const client = new WorkflowClient(conn.service, { workflowDefaults: { taskQueue: 'example' } });
const handle = await client.start(myWorkflow, { args: [foo, bar] });
// After
const client = new WorkflowClient(conn.service);
const handle = await client.start(myWorkflow, {
  args: [foo, bar],
  taskQueue: 'example',
  workflowId: 'a-meaningful-business-id',
});
```
Support Windows development (#385)
- Support was added for using and developing the SDK on Windows
- Thanks @cons0l3 and @cretz for the contribution

[workflow] Use vm instead of isolated-vm (#264)

Removes the node-gyp dependency and speeds up installation times
Uses Node's built-in AsyncLocalStorage implementation instead of our own
💥 Requires an additional workflow interceptor if using @temporalio/interceptors-opentelemetry

import { WorkflowInterceptors } from '@temporalio/workflow';
import {
  OpenTelemetryInboundInterceptor,
  OpenTelemetryOutboundInterceptor,
  OpenTelemetryInternalsInterceptor,
} from '@temporalio/interceptors-opentelemetry/lib/workflow';

export const interceptors = (): WorkflowInterceptors => ({
  inbound: [new OpenTelemetryInboundInterceptor()],
  outbound: [new OpenTelemetryOutboundInterceptor()],
  // Disposes of the internal AsyncLocalStorage used for
  // the otel workflow context manager.
  internals: [new OpenTelemetryInternalsInterceptor()], // <-- new
});

Unexpose the isolatePoolSize and isolateExecutionTimeout WorkerOptions

[0.15.0] - 2021-11-11

Bug Fixes

Fix type imports (#361)
Update core, changes for no more WF update errors (#366)

Failing a Workflow task before this change could put the workflow in a stuck state.
💥 [workflow] Throw if patches are used at Workflow top level (#369)
💥 [workflow] Cancel timer created by condition (#372)

Also clean up resources taken by the blocked condition.
This change is incompatible with old Workflow histories.
💥 [workflow] Ensure signals are always processed (#380)

This fixes a critical issue where the SDK was not processing history events in the right order, for example, patches and signals should always be delivered before other events in the context of a single Workflow Task.

This change is incompatible with old Workflow histories.

Features

💥 [workflow] Change condition parameter order (#371)

// Before
const conditionIsTrue = await condition('1s', () => someBooleanVariable);
// After
const conditionIsTrue = await condition(() => someBooleanVariable, '1s');

💥 Rename ExternalDependencies to Sinks (#370)
Support complication on Mac for aarch64-unknown-linux-gnu (#378)

[0.14.0] - 2021-11-03

Bug Fixes

Add missing index.d.ts to published files in core-bridge package (#347)
[docs] Update algolia index name (#350)
[core] Update core to gain infinite poll retries (#355)
[worker] Fix Worker possible hang after graceful shutdown period expires (#356)

Features

💥 [workflow] Rename createActivityHandle to proxyActivities (#351)

The function's usage remains the same, only the name was changed.

Before:

import { createActivityHandle } from '@temporalio/workflow';
import type * as activities from './activities';

const { greet } = createActivityHandle<typeof activities>({
  startToCloseTimeout: '1 minute',
});

After:

import { proxyActivities } from '@temporalio/workflow';
import type * as activities from './activities';

const { greet } = proxyActivities<typeof activities>({
  startToCloseTimeout: '1 minute',
});

Reasoning:

Clarify that the method returns a proxy
Avoid confusion with WorkflowHandle

💥 [workflow] Rename setListener to setHandler (#352)

BREAKING CHANGE: The function's usage remains the same, only the name was changed.

Before:

import { defineSignal, setListener, condition } from '@temporalio/workflow';
import { unblockSignal } from './definitions';

export const unblockSignal = defineSignal('unblock');

export async function myWorkflow() {
  let isBlocked = true;
  setListener(unblockSignal, () => void (isBlocked = false));
  await condition(() => !isBlocked);
}

After:

import { defineSignal, setHandler, condition } from '@temporalio/workflow';
import { unblockSignal } from './definitions';

export const unblockSignal = defineSignal('unblock');

export async function myWorkflow() {
  let isBlocked = true;
  setHandler(unblockSignal, () => void (isBlocked = false));
  await condition(() => !isBlocked);
}

Reasoning:

It was our go-to name initially but we decided against it when to avoid confusion with the WorkflowHandle concept
Handling seems more accurate about what the function is doing than listening
With listeners it sounds like you can set multiple listeners, and handler doesn't

[worker] Add SIGUSR2 to default list of shutdown signals (#346)

💥 [client] Use failure classes for WorkflowClient errors

Error handling for WorkflowClient and WorkflowHandle execute and result methods now throw WorkflowFailedError with the specific TemporalFailure as the cause. The following error classes were renamed:
- WorkflowExecutionFailedError was renamed WorkflowFailedError.
- WorkflowExecutionContinuedAsNewError was renamed WorkflowContinuedAsNewError.

Before:

try {
  await WorkflowClient.execute(myWorkflow, { taskQueue: 'example' });
} catch (err) {
  if (err instanceof WorkflowExecutionFailedError && err.cause instanceof ApplicationFailure) {
    console.log('Workflow failed');
  } else if (err instanceof WorkflowExecutionTimedOutError) {
    console.log('Workflow timed out');
  } else if (err instanceof WorkflowExecutionTerminatedError) {
    console.log('Workflow terminated');
  } else if (err instanceof WorkflowExecutionCancelledError) {
    console.log('Workflow cancelled');
  }
}

After:

try {
  await WorkflowClient.execute(myWorkflow, { taskQueue: 'example' });
} catch (err) {
  if (err instanceof WorkflowFailedError) {
  ) {
    if (err.cause instanceof ApplicationFailure) {
      console.log('Workflow failed');
    } else if (err.cause instanceof TimeoutFailure) {
      console.log('Workflow timed out');
    } else if (err.cause instanceof TerminatedFailure) {
      console.log('Workflow terminated');
    } else if (err.cause instanceof CancelledFailure) {
      console.log('Workflow cancelled');
    }
}

Features

Support bundling Workflow code prior to Worker creation (#336)

💥 Refactor WorkflowHandle creation (#343)

WorkflowClient.start now returns a WorkflowHandle
WorkflowHandle no longer has start, signalWithStart and execute methods
WorkflowClient.signalWithStart was added
To get a handle to an existing Workflow use WorkflowClient.getHandle
wf.createChildWorklowHandle was renamed to wf.startChild and immediately starts the Workflow
wf.executeChild replaces ChildWorkflowHandle.execute
wf.createExternalWorkflowHandle was renamed to wf.getExternalWorkflowHandle
