`ApplicationRef`, preventing confusing differences between the two as
more APIs start using the `PendingTasks` that may not be tracked by
`NgZone`.
BREAKING CHANGE: `ComponentFixture.whenStable` now matches the
`ApplicationRef.isStable` observable. Prior to this change, stability
of the fixture did not include everything that was considered in
`ApplicationRef`. `whenStable` of the fixture will now include unfinished
router navigations and unfinished `HttpClient` requests. This will cause
tests that `await` the `whenStable` promise to time out when there are
incomplete requests. To fix this, remove the `whenStable`,
instead wait for another condition, or ensure `HttpTestingController`
mocks responses for all requests. Try adding `HttpTestingController.verify()`
before your `await fixture.whenStable` to identify the open requests.
Also, make sure your tests wait for the stability promise. We found many
examples of tests that did not, meaning the expectations did not execute
within the test body.
In addition, `ComponentFixture.isStable` would synchronously switch to
true in some scenarios but will now always be asynchronous.

According to the HTML specification most attributes are defined as strings, however some can be interpreted as different types like booleans or numbers. [In the HTML standard](https://html.spec.whatwg.org/multipage/common-microsyntaxes.html#boolean-attributes), boolean attributes are considered `true` if they are present on a DOM node and `false` if they are omitted. Common examples of boolean attributes are `disabled` on interactive elements like `<button>` or `checked` on `<input type="checkbox">`. Another example of an attribute that is defined as a string, but interpreted as a different type is the `value` attribute of `<input type="number">` which logs a warning and ignores the value if it can't be parsed as a number.
Historically, authoring Angular inputs that match the native behavior in a type-safe way has been difficult for developers, because Angular interprets all static attributes as strings. While some recent TypeScript versions made this easier by allowing setters and getters to have different types, supporting this pattern still requires a lot of boilerplate and additional properties to be declared. For example, currently developers have to write something like this to have a `disabled` input that behaves like the native one:
```typescript
import {Directive, Input} from '@angular/core';
@Directive({selector: 'mat-checkbox'})
export class MatCheckbox {
@Input()
get disabled() {
return this._disabled;
}
set disabled(value: any) {
this._disabled = typeof value === 'boolean' ? value : (value != null && value !== 'false');
}
private _disabled = false;
}
```
This feature aims to address the issue by introducing a `transform` property on inputs. If an input has a `transform` function, any values set through the template will be passed through the function before being assigned to the directive instance. The example from above can be rewritten to the following:
```typescript
import {Directive, Input, booleanAttribute} from '@angular/core';
@Directive({selector: 'mat-checkbox'})
export class MatCheckbox {
@Input({transform: booleanAttribute}) disabled: boolean = false;
}
```
These changes also add the `booleanAttribute` and `numberAttribute` utilities to `@angular/core` since they're common enough to be useful for most projects.

`setDisabledState` is supposed to be called whenever the disabled state of a control changes, including upon control creation. However, a longstanding bug caused the method to not fire when an *enabled* control was attached. This bug was fixed in v15.
This had a side effect: previously, it was possible to instantiate a reactive form control with `[attr.disabled]=true`, even though the the corresponding control was enabled in the model. (Note that the similar-looking property binding version `[disabled]=true` was always rejected, though.) This resulted in a mismatch between the model and the DOM. Now, because `setDisabledState` is always called, the value in the DOM will be immediately overwritten with the "correct" enabled value.
Users should instead disable the control directly in their model. (There are many ways to do this, such as using the `{value: 'foo', disabled: true}` constructor format, or immediately calling `FooControl.disable()` in `ngOnInit`.)
If this incompatibility is too breaking, you may also opt out using `FormsModule.withConfig` or `ReactiveFormsModule.withConfig` at the time you import it, via the `callSetDisabledState` option.
However, there is an exceptional case: radio buttons. Because Reactive Forms models the entire group of radio buttons as a single `FormControl`, there is no way to control the disabled state for individual radios, so they can no longer be configured as disabled.
In this PR, we have special cased radio buttons to ignore their first call to `setDisabledState` when in `callSetDisabledState: 'always'` mode. This preserves the old behavior.

Consider the case in which `FormBuilder` is used to construct a group with an optional field:
```
const controls = { name: fb.control('') };
const foo: FormGroup<{
name: FormControl<string | null>;
address?: FormControl<string | null>;
}> = fb.group<{
name: FormControl<string | null>;
address?: FormControl<string | null>;
}>(controls);
```
Today, with fully strict TypeScript settings, the above will not compile:
```
Types of property 'controls' are incompatible.
Type '{ name: FormControl<string | null>; address?: FormControl<FormGroup<SubFormControls> | null | undefined> | undefined; }' is not assignable to type '{ name: FormControl<string | null>; address?: FormGroup<SubFormControls> | undefined; }'.
```
Notice that the `fb.group(...)` is calculating the following type for address: `address?: FormControl<FormGroup<string|null>`. This is clearly wrong -- an extraneous `FormControl` has been added!
This is coming from the calculation of the result type of `fb.group(...)`. In the type definition, if we cannot detect the outer control type, [we assume it's just an unwrapped value, and automatically wrap it in `FormControl`](https://github.com/angular/angular/blob/14.0.0/packages/forms/src/form_builder.ts#L66).
Because the optional `{address?: FormControl<string|null>}` implicitly makes the RHS have type `FormControl<string|null>|undefined`, [the relevant condition is not satisfied](https://github.com/angular/angular/blob/14.0.0/packages/forms/src/form_builder.ts#L55). In particular, the condition expects just `FormGroup<T>`, not `FormGroup<T>|undefined`. So we assume `T` is a value type, and it gets wrapped with `FormControl`.
The solution is to add the cases where `undefined` is included in the union type when detecting which control `T` is (if any).

Previously, using `FormBuilder` with a union type would produce unions of *controls*:
```
// `foo` has type `FormControl<string>|FormControl<number>`.
const c = fb.nonNullable.group({foo: 'bar' as string | number});
```
This actually works in many cases, due to how extraordinarily powerful Typescript's distributive types are (e.g. `value` still has type `string|number`), but it is subtly incorrect. Here is a code example that exposes the reason the inference is incorrect. It exploits the fact that Typescript will not "un-distribute" a type, producing an obviously spurious error:
```
// fc gets an inferred distributive union type `FormControl<string> | FormControl<number>`
let fc = c.controls.foo;
// Error: Type 'FormControl<string | number>' is not assignable to type 'FormControl<string> | FormControl<number>'.
fc = new FormControl<string|number>('', {initialValueIsDefault: true});
```
Instead, we want the union to apply to the *values*:
```
// `foo` should have type `FormControl<string|number>`.
const c = fb.nonNullable.group({foo: 'bar' as string | number});
```
Essentially, we want to prevent Typescript from distributing the type. [As specified in the handbook](https://www.typescriptlang.org/docs/handbook/2/conditional-types.html#distributive-conditional-types):
> Typically, distributivity is the desired behavior. To avoid that behavior, you can surround each side of the extends keyword with square brackets.

Based on early feedback, calling `fb.nonNullable.group(...)` continues to be clunky for a form with many such groups. Allowing `NonNullableFormBuilder` to be directly injected enables the following:
```

PR Close#45904
With typed forms, all `FormControl`s are nullable by default, because they can be reset to `null`. This behavior is possible to change by passing the option `initialValueIsDefault: true`. However, in a large form, this is extremely cumbersome, as the option must be repeated over and over. Additionally, it is not possible to take full advantage of `FormBuilder`, since `FormBuilder.group` and `FormBuilder.array` will produce nullable controls.
This PR introduces a new accessor `FormBuilder.nonNullable`, which produces *non-nullable* controls. Specifically, any call to `.control` will produce controls with `{initialValueIsDefault: true}`, and calls to `.array` or `.group` that implicitly build inner controls will have the same effect.
```ts
let nfb = new FormBuilder().nonNullable;
let name = nfb.group({who: 'Alex'}); // FormGroup<{who: FormControl<string>}>
name.reset();

* Makes APF-built packages also handle types for `ts_library` targets consistently.
* Allows us to ensure APF entry-points have `d.ts` _always_ bundled (working with ESM

When an `NgModel` is created within a `form`, it receives an `NgControl` based on its `name`, but
the control doesn't get swapped out if the name changes. This can lead to problems if the `NgModel`
is part of an `ngFor`, because the name can change based on its position in the list and a new
control can be defined with the same name, leading us to having multiple directives pointing to
the same control. For example, if we start off with a list like :
```
[0, 1, 2]; -> [NgModel(0), NgModel(1), NgModel(2)]
```
Then we remove the second item:
```
[0, 2]; -> [NgModel(0), NgModel(2)]
```
And finally, if we decide to add an item to the end of the list, we'll already have a control for
index 2, causing the list to look like:
```
[0, 2, 3]; -> [NgModel(0), NgModel(2), NgModel(2)]
```
These changes fix the issue by removing the old control when the `name` of the directive changes.

* Our `ngtsc` test setup calls the private `matchFiles` function from TS. I had to update our usage, because a new parameter was added.
* There was one place where we were setting the readonly `hasTrailingComma` property. I updated the usage to pass in the value when constructing the object instead.

Specifically: narrow the type used for form statuses from string to a union of possible statuses. Change the API methods from any to use the new type.
This is a breaking change. However, as discussed in the PR, breakage seems minimal, and google3 has been prepped to land this.
Background: we uncovered these any typings in the course of design work for typed forms. They could be fixed in a non-breaking manner by piggybacking them on top of the new typed forms generics, but it would be much cleaner to fix them separately if possible.
BREAKING CHANGE:
A new type called `FormControlStatus` has been introduced, which is a union of all possible status strings for form controls. `AbstractControl.status` has been narrowed from `string` to `FormControlStatus`, and `statusChanges` has been narrowed from `Observable<any>` to `Observable<FormControlStatus>`. Most applications should consume the new types seamlessly. Any breakage caused by this change is likely due to one of the following two problems: (1) the app is comparing `AbstractControl.status` against a string which is not a valid status; or, (2) the app is using `statusChanges` events as if they were something other than strings.

The `NgControlStatusGroup` directive is shared between template-driven and reactive form modules. In cases when
only reactive forms module is present, the `NgControlStatusGroup` directive is still activated on all `<form>`
elements, but if there is no other reactive directive applied (such as `formGroup`), corresponding `ControlContainer`
token is missing, thus causing exceptions (since `NgControlStatusGroup` directive relies on it to determine the
status). This commit updates the logic to handle the case when no `ControlContainer` is present (effectively making
directive logic a noop in this case).
Alternative approach (more risky) worth considering in the future is to split the `NgControlStatusGroup` into
2 directives with different set of selectors and include them into template-driven and reactive modules separately.
The downside is that these directives might be activated simultaneously on the same element (e.g. `<form>`),

This expands the deprecation message that started to pop up in v11.0.3
after the landing of commit e148382bd0,
that deprecated the `{[key: string]: any}` type for the options property of the `FormBuilder.group` method.
It turns out that having a custom validator declared as
`{ validators: (group: FormGroup) => ValidationErrors|null }` works in practice,
but is now inferred by TS as the deprecated version of `group`
(because `FormGroup` is a subclass of `AbstractControl` that `ValidatorFn` expects).
We considered the possibility of tweaking the forms API to accept such validators,
but it turns out to generate too many changes in the framework or possible breaking changes for Angular users.
We settled for a more explicit deprecation message, elaborated with the help of @petebacondarwin.
This will hopefully help developers to understand why the deprecation warning is showing up
when they think they are already using the non-deprecated overload.

DEPRECATION:
Mark the {[key: string]: any} type for the options property of the FormBuilder.group method as deprecated.
Using AbstractControlOptions gives the same functionality and is type-safe.

The value of a `FormControl` is treated in a special way (called boxed values) when it's an object with exactly
2 fields: `value` and `disabled`. This commit adds a test which verifies that an object is not treated as a boxed
value when `disabled` field is present, but `value` is missing.
PR Close#39801
Currently when an instance of the `FormControlName` directive is destroyed, the Forms package invokes
the `cleanUpControl` to clear all directive-specific logic (such as validators, onChange handlers,
etc) from a bound control. The logic of the `cleanUpControl` function should revert all setup
performed by the `setUpControl` function. However the `cleanUpControl` is too aggressive and removes
all callbacks related to the onChange and disabled state handling. This is causing problems when
a form control is bound to multiple FormControlName` directives, causing other instances of that
directive to stop working correctly when the first one is destroyed.
This commit updates the cleanup logic to only remove callbacks added while setting up a control
for a given directive instance.
The fix is needed to allow adding `cleanUpControl` function to other places where cleanup is needed
(missing this function calls in some other places causes memory leak issues).
PR Close#39623
Prior to this commit, the `cleanUpControl` function (responsible for cleaning up control instance)
was not taking validators into account. As a result, these validators remain registered on a detached
form control instance, thus causing memory leaks. This commit updates the `cleanUpControl` function
logic to also run validators cleanup.
As a part of this change, the logic to setup and cleanup validators was refactored and moved to
separate functions (with completely opposite behavior), so that they can be reused in the future.
This commit doesn't add the `cleanUpControl` calls to all possible places, it just fixes the cases
where this function is being called, but doesn't fully perform a cleanup. The `cleanUpControl`
function calls will be added to other parts of code (to avoid more memory leaks) in a followup PR.

This commit improves the ngModel docs, specifically:
- clarifies purpose of the name attribute in ngModelOptions
- clarifies on the interaction with a parent form or lack thereof
- fix inconsistency with analogy for two-way binding
- cleans up some typos and extra wordiness
- clarifies language around common properties
- adds missing preposition to commit message format origins

This commit refactors validators-related logic that is common across most of the directives.
A couple notes on this refactoring:
* common logic was moved to the `AbstractControlDirective` class (including `validator` and
`asyncValidator` getters)
* sync/async validators are now composed in `AbstractControlDirective` class eagerly when validators
are set with `_setValidators` and `_setAsyncValidators` calls and the result is stored in directive
instance (thus getters return cached versions of validator fn). This is needed to make sure composed
validator function remains the same (retains its identity) for a given directive instance, so that
this function can be added and later removed from an instance of an AbstractControl-based class
(like `FormControl`). Preserving validator function is required to perform proper cleanup (in followup
PRs) of the AbstractControl-based classes when a directive is destroyed.

Prior to this change, the `validators` and `asyncValidators` fields of a few Forms directives
were typed as `any[]`. This commit updates the types and makes them consistent for all directives
in the Forms package.
BREAKING CHANGE:
Directives in the `@angular/forms` package used to have `any[]` as a type of `validators` and
`asyncValidators` arguments in constructors. Now these arguments are properly typed, so if your
code relies on directive constructor types it may require some updates to improve type safety.
PR Close#38944
It's perfectly valid for an abstract control not to have a defined parent; yet previously the
types were asserting that AbstractControl#parent is not a null value. This changes correctly
reflects the run-time behavior through the types.
BREAKING CHANGE: Type of AbstractFormControl.parent now includes null
`null` is now included in the types of .parent. If you don't already have a check for this case,
the TypeScript compiler might compain. A v11 migration exists which adds the not-null assertion
operator where necessary.
In an unlikely case your code was testing the parnet against undefined with sitrct equality,
you'll need to change this to `=== null` instead, since the parent is not explicily initialized
with `null` instead of being left `undefined`.

NG_VALUE_ACCESSOR is a multi injection token, users can and
should expect more than one ControlValueAccessor to be
available (and this is how it is used in @angular/forms).
This is now reflected in the definition of the injection token
by typing it as an array of ControlValueAccessor. The motivating
reason is that using the programmatic Injector api will now
type Injector#get correspondingly.
fixes#29351
BREAKING CHANGES
NG_VALUE_ACCESSOR is now typed as a readonly array rather than
a mutable scalar. It is used as a multi injection token and as
such it should always be expected that more than one accessor
may be returned.

This commit ensures that the `updateValueAndValidity` method takes the
`asyncValidator` into consideration to emit on the `statusChanges` observables.
This is necessary so that any subsequent changes are emitted properly to any
subscribers.
Closes#20424Closes#14542
BREAKING CHANGE:
Previously if FormControl, FormGroup and FormArray class instances had async validators
defined at initialization time, the status change event was not emitted once async validator
completed. After this change the status event is emitted into the `statusChanges` observable.
If your code relies on the old behavior, you can filter/ignore this additional status change
event.

Prior to this commit, a lot of internal-only class properties and methods (such as `ngOnChanges`)
of the Forms package directives were exposed on angular.io website. These fields are not expected
to be called externally (they are used/invoked by framework only), since they are part of internal
implementations of the following interfaces:
* Angular lifecycle hook interfaces
* ControlValueAccessor interface
* Validator interface
Having these internal-only fields in docs creates unnecessary noise on directive detail pages.
This commit adds the `@nodoc` annotation to these properties and methods to keep fields in the
golden files, but hide them in docs.

This commit performs minor refactoring in Forms package to get rid of duplicate functions.
It looks like the functions were duplicated due to a slightly different type signatures, but
their logic is completely identical. The logic in retained functions remains the same and now
these function also accept a generic type to achieve the same level of type safety.

A util file is added to forms test package:
- it exposes simpleAsyncValidator, asyncValidator and asyncValidatorReturningObservable validators
- it refactors simpleAsyncValidator and asyncValidator to use common promise creation code
- it exposes currentStateOf allowing to get the validation state of a list of AbstractControl
Closes#37831
PR Close#38020
This commit refactors the way we store validators in AbstractControl-based classes:
in addition to the combined validators function that we have, we also store the original list of validators.
This is needed to have an ability to clean them up later at destroy time (currently it's problematic since
they are combined in a single function).
The change preserves backwards compatibility by making sure public APIs stay the same.
The only public API update is the change to the `AbstractControl` class constructor to extend the set
of possible types that it can accept and process (which should not be breaking).

The method was previously looping through all controls, even after finding at least one that

Use an explicit type guard when checking if a given object is of type AbstractControlOptions,

Remove `looseIdentical` implementation and instead use the ES2015 `Object.is` in its place.
They behave exactly the same way except for `+0`/`-0`.
`looseIdentical(+0, -0)` => `true`
`Object.is(+0, -0)` => `false`
Other than the difference noted above, this is not be a breaking change because:
1. `looseIdentical` is a private API
2. ES2015 is listed as a mandatory polyfill in the [browser support
guide](https://angular.io/guide/browser-support#mandatory-polyfills)
3. Also note that `Ivy` already uses `Object.is` in `bindingUpdated`.
