aebf165359 fix(zone.js): should ignore multiple resolve call (#45283)
Close #44913

The following case is not handled correctly by `zone.js`.
```
const delayedPromise = new Promise((resolve) => {
  setTimeout(resolve, 1, 'timeout');
});

new Promise((resolve) => {
  resolve(delayedPromise);
  resolve('second call');
}).then(console.log);
```

It should output `timeout`, since the promise is resolved by the
1st resolve, the `second call` should be ignored.

So this is a bug that the original implementation not ensure the
`resolve` is only called once.

4ea70e36b9 fix(zone.js): swallow the error when the element callback is not patchable (#45400)
The `patchCallbacks` is used for patching the `document.registerElement` and
`customElements.define`. We explicitly wrap the patching code into try-catch since
callbacks may be already patched by other web components frameworks (e.g. LWC), and they
make those properties non-writable. This means that patching callback will throw an error
`cannot assign to read-only property`. See this code as an example:
https://github.com/salesforce/lwc/blob/master/packages/@lwc/engine-core/src/framework/base-bridge-element.ts#L180-L186
We don't want to stop the application rendering if we couldn't patch some
callback, e.g. `attributeChangedCallback`.

e2eaac34b0 fix(zone.js): read Symbol.species safely (#45369)
We must read `Symbol.species` safely because `this` may be anything. For instance, `this`
may be an object without a prototype (created through `Object.create(null)`); thus
`this.constructor` will be undefined. One of the use cases is SystemJS creating
prototype-less objects (modules) via `Object.create(null)`. The SystemJS creates an empty
object and copies promise properties into that object (within the `getOrCreateLoad`
function). The zone.js then checks if the resolved value has the `then` method and invokes
it with the `value` context. Otherwise, this will throw an error: `TypeError: Cannot read
properties of undefined (reading 'Symbol(Symbol.species)')`.

f19b36f462 fix(zone.js): in TaskTrackingZoneSpec track a periodic task until it is cancelled (#45391)
Before this change, the macrotask for `setInterval(callback, ms)` was no
longer tracked by `TaskTrackingZoneSpec` after the `callback` was
invoked for the first time. Now the periodic macrotask is tracked until
it is cancelled, e.g. `clearInterval(id)`.

BREAKING CHANGE: in TaskTrackingZoneSpec track a periodic task until it is cancelled

The breaking change is scoped only to the plugin
`zone.js/plugins/task-tracking`. If you used `TaskTrackingZoneSpec` and
checked the pending macroTasks e.g. using `(this.ngZone as any)._inner
._parent._properties.TaskTrackingZone.getTasksFor('macroTask')`, then
its behavior slightly changed for periodic macrotasks. For example,
previously the `setInterval` macrotask was no longer tracked after its
callback was executed for the first time. Now it's tracked until
the task is explicitly cancelled, e.g  with `clearInterval(id)`.

0f298a13db refactor(zone.js): remove onProp eventNames array to reduce the bundle size (#40962)
Zone.js supports the google closure compiler in the advance optimization mode,
to prevent closure compiler modify the `onProperty` name such as `Element.prototype.onclick`,
Zone.js implements the `onProperty` patch logic by declaring all the
event names in the source code, this increases the bundle size and also require
updating the event names array to keep the information updated.

Now google closure compiler has the required event names defined in the built-in
externs files, so zone.js can use more simple implementation and decrease the bundle size
of zone.js (about 4k).

8efbdb57c1 fix(zone.js): patch global instead of Mocha object (#45047)
Close #42834

In the new version fo Mocha, all global test functions are from `global`
object instead of `Mocha` object. Adn the current `zone.js` Mocha
patch's logic looks like this.

```
global.describe = Mocha.describe = function() {
  return originalMochaDescribe.apply(this, arguments);
}
```

and `originalMochaDescribe` is the unpathced Mocha implementation
looks like this

```
function describe() {
  return context.describe(...);
}
```

And the `context` will finally delegate to `global.describe()`,
so the current `zone.js` patch causes infinite loop.

This commit will not patch function of `Mocha` object any longer.

dea7234a76 fix(zone.js): async-test should only call done once (#45025)
`AsyncTestZoneSpec` triggers jasmine `done()` function multiple times
and causes warning

```
An asynchronous function called its 'done' callback more than once. This is a bug in the spec, beforeAll, beforeEach, afterAll, or afterEach function in question. This will be treated as an error in a future version. See<https://jasmine.github.io/tutorials/upgrading_to_Jasmine_4.0#deprecations-due-to-calling-done-multiple-times> for more information
```

The reproduce case will be running some `Zone.run()` inside
`waitForAsync()`.

```
it('multiple done', waitForAsync(() => {
  Zone.current.run(() => {});
  Zone.current.run(() => {});
}));
```

The reason the `done()` is called in the `onInvoke()` hook is to handle
the case that the testBody is totally sync, but we should only do this
check for the entry function not for all `Zone.run()` scenario.

Another issue is if we run nested zone inside `waitForAsync()`, the
`onHasTask()` hook will be triggered multiple times, and cause `done()`
be triggered multiple times, so we need to only trigger the `done()`
when the zone is `AsyncTestZone`.

008eaf3b7d fix(zone.js): should continue to executue listeners when throw error (#41562)
Close #41522

`zone.js` patches event listeners and run all event listeners together, if
one event handler throws error, the listeners afterward may not be invoked.

Reproduction:

```
export class AppComponent implements AfterViewInit {
  @ViewChild('btn') btn: ElementRef;
  title = 'event-error';

  constructor(private ngZone: NgZone) {}

  ngAfterViewInit() {
    this.ngZone.runOutsideAngular(() => {
      this.btn.nativeElement.addEventListener('click', () => {
        throw new Error('test1');
      });
      this.btn.nativeElement.addEventListener('click', () => {
        console.log('add eventlistener click');
      });
    });
  }
}
```

Until now no Angular users report this issue becuase in the `ngZone`, all
error will be caught and will not rethrow, so the event listeners afterward
will still continue to execute, but if the event handlers are outside of `ngZone`,
the error will break the execution.

This commit catch all errors, and after all event listeners finished invocation,
rethrow the errors in seperate `microTasks`, the reason I am using `microTask` here
is to handle multiple errors case.

0652b29f62 fix(zone.js): setTimeout patch should clean tasksByHandleId cache. (#40586)
Close #40387

Currently zone.js patches `setTimeout` and keeps a `tasksByHandleId` map to keep `timerId` <-> `ZoneTask`
relationship. This is needed so that when `clearTimeout(timerId)` is called, zone.js can find the associated
`ZoneTask`. Now zone.js set the `tasksByHandleId` map in the `scheduleTask` function, but if the `setTimeout`
is running in the `FakeAsyncZoneSpec` or any other `ZoneSpec` with `onScheduleTask` hooks. The `scheduleTask`
in `timer` patch may not be invoked.

For example:

```
fakeAsync(() => {
  setTimeout(() => {});
  tick();
});
```

In this case, the `timerId` kept in the `tasksByHandleId` map is not cleared.
This is because the `FakeAsyncZoneSpec` in the `onScheduleTask` hook looks like this.

```
onScheduleTask(delegate, ..., task) {
  fakeAsyncScheduler.setTimeout(task);
  return task;
}
```

Because `FakeAsyncZoneSpec` handles the task itself and it doesn't call `parentDelegate.onScheduleTask`,
therefore the default `scheduleTask` in the `timer` patch is not invoked.

In this commit, the cleanup logic is moved from `scheduleTask` to `setTimeout` patch entry to
avoid the memory leak.

42a164f522 build: upgrade angular build, integration/bazel and @angular/bazel package to rule_nodejs 2.2.0 (#39182)
Updates to rules_nodejs 2.2.0. This is the first major release in 7 months and includes a number of features as well
as breaking changes.

Release notes: https://github.com/bazelbuild/rules_nodejs/releases/tag/2.0.0

Features of note for angular/angular:

* stdout/stderr/exit code capture; this could be potentially be useful

* TypeScript (ts_project); a simpler tsc rule that ts_library that can be used in the repo where ts_library is too
  heavy weight

Breaking changes of note for angular/angular:

* loading custom rules from npm packages: `ts_library` is no longer loaded from `@npm_bazel_typescript//:index.bzl`
  (which no longer exists) but is now loaded from `@npm//@bazel/typescript:index.bzl`

* with the loading changes above, `load("@npm//:install_bazel_dependencies.bzl", "install_bazel_dependencies")` is
  no longer needed in the WORKSPACE which also means that yarn_install does not need to run unless building/testing
  a target that depends on @npm. In angular/angular this is a minor improvement as almost everything depends on @npm.

* @angular/bazel package is also updated in this PR to support the new load location; Angular + Bazel users that
  require it for ng_package (ng_module is no longer needed in OSS with Angular 10) will need to load from
  `@npm//@angular/bazel:index.bzl`. I investigated if it was possible to maintain backward compatability for the old
  load location `@npm_angular_bazel` but it is not since the package itself needs to be updated to load from
  `@npm//@bazel/typescript:index.bzl` instead of `@npm_bazel_typescript//:index.bzl` as it depends on ts_library
  internals for ng_module.

* runfiles.resolve will now throw instead of returning undefined to match behavior of node require

Other changes in angular/angular:

* integration/bazel has been updated to use both ng_module and ts_libary with use_angular_plugin=true.
  The latter is the recommended way for rules_nodejs users to compile Angular 10 with Ivy. Bazel + Angular ViewEngine is
  supported with @angular/bazel <= 9.0.5 and Angular <= 8. There is still Angular ViewEngine example on rules_nodejs
  https://github.com/bazelbuild/rules_nodejs/tree/stable/examples/angular_view_engine on these older versions but users
  that want to update to Angular 10 and are on Bazel must switch to Ivy and at that point ts_library with
  use_angular_plugin=true is more performant that ng_module. Angular example in rules_nodejs is configured this way
  as well: https://github.com/bazelbuild/rules_nodejs/tree/stable/examples/angular. As an aside, we also have an
  example of building Angular 10 with architect() rule directly instead of using ts_library with angular plugin:
  https://github.com/bazelbuild/rules_nodejs/tree/stable/examples/angular_bazel_architect.

NB: ng_module is still required for angular/angular repository as it still builds ViewEngine & @angular/bazel
also provides the ng_package rule. ng_module can be removed in the future if ViewEngine is no longer needed in
angular repo.

* JSModuleInfo provider added to ng_module. this is for forward compat for future rules_nodejs versions.

  (which no longer exists) but is now loaded from `@npm//@bazel/typescript:index.bzl`

* with the loading changes above, `load("@npm//:install_bazel_dependencies.bzl", "install_bazel_dependencies")` is
  no longer needed in the WORKSPACE which also means that yarn_install does not need to run unless building/testing
  a target that depends on @npm. In angular/angular this is a minor improvement as almost everything depends on @npm.

* @angular/bazel package is also updated in this PR to support the new load location; Angular + Bazel users that
  require it for ng_package (ng_module is no longer needed in OSS with Angular 10) will need to load from
  `@npm//@angular/bazel:index.bzl`. I investigated if it was possible to maintain backward compatability for the old
  load location `@npm_angular_bazel` but it is not since the package itself needs to be updated to load from
  `@npm//@bazel/typescript:index.bzl` instead of `@npm_bazel_typescript//:index.bzl` as it depends on ts_library
  internals for ng_module.

* runfiles.resolve will now throw instead of returning undefined to match behavior of node require

Other changes in angular/angular:

* integration/bazel has been updated to use both ng_module and ts_libary with use_angular_plugin=true.
  The latter is the recommended way for rules_nodejs users to compile Angular 10 with Ivy. Bazel + Angular ViewEngine is
  supported with @angular/bazel <= 9.0.5 and Angular <= 8. There is still Angular ViewEngine example on rules_nodejs
  https://github.com/bazelbuild/rules_nodejs/tree/stable/examples/angular_view_engine on these older versions but users
  that want to update to Angular 10 and are on Bazel must switch to Ivy and at that point ts_library with
  use_angular_plugin=true is more performant that ng_module. Angular example in rules_nodejs is configured this way
  as well: https://github.com/bazelbuild/rules_nodejs/tree/stable/examples/angular. As an aside, we also have an
  example of building Angular 10 with architect() rule directly instead of using ts_library with angular plugin:
  https://github.com/bazelbuild/rules_nodejs/tree/stable/examples/angular_bazel_architect.

NB: ng_module is still required for angular/angular repository as it still builds ViewEngine & @angular/bazel
also provides the ng_package rule. ng_module can be removed in the future if ViewEngine is no longer needed in
angular repo.

* JSModuleInfo provider added to ng_module. this is for forward compat for future rules_nodejs versions.
  @josephperrott, this touches `packages/bazel/src/external.bzl` which will make the sync to g3 non-trivial.

19d543f71e fix(zone.js): disable wrap uncaught promise rejection should handle primitive value (#38476)
Close #38334.

zone.js provides a flag DISABLE_WRAPPING_UNCAUGHT_PROMISE_REJECTION to let zone.js
throw the original error instead of wrap it when uncaught promise rejection found.
But the rejection value could be anything includes primitive value such as number.
In that case, we should not attach any additional properties to the value.

d92a0dd72f fix(zone.js): should invoke xhr send task when no response error occurs (#38836)
Close #38795

in the XMLHttpRequest patch, when get `readystatechange` event, zone.js try to
invoke `load` event listener first, then call `invokeTask` to finish the
`XMLHttpRequest::send` macroTask, but if the request failed because the
server can not be reached, the `load` event listener will not be invoked,
so the `invokeTask` of the `XMLHttpRequest::send` will not be triggered either,
so we will have a non finished macroTask there which will make the Zone
not stable, also memory leak.

So in this PR, if the `XMLHttpRequest.status = 0` when we get the `readystatechange`
event, that means something wents wrong before we reached the server, we need to
invoke the task to finish the macroTask.

40096bee00 fix(zone.js): run tests in umd format (#37582)
Since the `defineProperty` not swallow error any longer, now the tests compile
source code in `commonjs` mode, and the code generated includes the code like this
```
Object.defineProperty(exports, "__esModule", {value: true});
```

And the `exports` is undefined in some browsers, but the error is swallowed before
this PR, and all tests run successfully, but it is not correct behavior. After this PR,
the code above failed. So we need to compile the source code in `umd` mode.

45a73dddfd fix(zone.js): defineProperty patch should not swallow error (#37582)
Close #37432

zone.js monkey patches the `Object.defineProperty` API long time ago
angular/zone.js@383b479
to resolve issues in very old version of Chrome web which override the
property of `CustomElements`, and this is not an issue any longer, so
we want to remove this monkey patch, since it may swallow the errors when the user
want to define property on unconfigurable or frozen object properties.
But currently there are several apps and tests depends on this patch, since
it also change the `configurable` property to `true` by default, so
in this PR we update the logic to not to swallow error any longer unless the property
is the callbacks of `document.registerElements`.

BREAKING CHANGE:

ZoneJS no longer swallows errors produced by `Object.defineProperty` calls.

Prior to this change, ZoneJS monkey patched `Object.defineProperty` and if there is an error
(such as the property is not configurable or not writable) the patched logic swallowed it
and only console.log was produced. This behavior used to hide real errors,
so the logic is now updated to trigger original errors (if any). One exception
where the patch remains in place is `document.registerElement`
(to allow smooth transition for code/polyfills that rely on old behavior in legacy browsers).
If your code relies on the old behavior (where errors were not thrown before),
you may need to update the logic to handle the errors that are no longer masked by ZoneJS patch.

96aa14df01 fix(zone.js): zone patch rxjs should return null _unsubscribe correctly. (#37091)
Close #31684.

In some rxjs operator, such as `retryWhen`, rxjs internally will set
`Subscription._unsubscribe` method to null, and the current zone.js monkey patch
didn't handle this case correctly, even rxjs set _unsubscribe to null, zone.js
still return a function by finding the prototype chain.

This PR fix this issue and the following test will pass.

```
const errorGenerator = () => {
  return throwError(new Error('error emit'));
};

const genericRetryStrategy = (finalizer: () => void) => (attempts: Observable<any>) =>
    attempts.pipe(
      mergeMap((error, i) => {
        const retryAttempt = i + 1;
        if (retryAttempt > 3) {
          return throwError(error);
        }
        return timer(retryAttempt * 1);
      }),
      finalize(() => finalizer()));

  .pipe(
    retryWhen(genericRetryStrategy(() => {
      expect(log.length).toBe(3);
      done();
    })),

c2b4d92708 feat(zone.js): patch jasmine.createSpyObj to make properties enumerable to be true (#34624)
Close #33657

in jasmine 3.5, there is a new feature, user can pass a properties object to `jasmine.createSpyObj`

```
const spy = jasmine.createSpyObj('spy', ['method1'], {prop1: 'foo'});
expect(spy.prop1).toEqual('foo');
```

This case will not work for Angular TestBed, for example,

```
describe('AppComponent', () => {
  beforeEach(() => {

    //Note the third parameter
    // @ts-ignore
    const someServiceSpy = jasmine.createSpyObj('SomeService', ['someFunction'], ['aProperty']);

    TestBed.configureTestingModule({
      declarations: [
        AppComponent
      ],
      providers: [
        {provide: SomeService, useValue: someServiceSpy},
      ]
    }).compileComponents();

  });

  it('should create the app', () => {
    //spyObj will have someFunction, but will not have aProperty
    let spyObj = TestBed.get(SomeService);
  });
```

Because `jasmine.createSpyObj` will create the `aProperty` with `enumerable=false`,
and `TestBed.configureTestingModule` will try to copy all the properties from spyObj to
the injected service instance. And because `enumerable` is false, so the property (here is aProperty)
will not be copied.

This PR will monkey patch the `jasmine.createSpyObj` and make sure the new property's
`enumerable=true`.
