Carlos Ortiz García 3aba7ebe6a feat(core): Introduce TestBed.inject to replace TestBed.get (#32200)
TestBed.get is not type safe, fixing it would be a massive breaking
change. The Angular team has proposed replacing it with TestBed.inject
and deprecate TestBed.get.

Deprecation from TestBed.get will come as a separate commit.

Issue #26491
Fixes #29905

BREAKING CHANGE: Injector.get now accepts abstract classes to return
type-safe values. Previous implementation returned `any` through the
deprecated implementation.

Kristiyan Kostadinov c885178d5f refactor(ivy): move directive, component and pipe factories to ngFactoryFn (#31953)
Reworks the compiler to output the factories for directives, components and pipes under a new static field called `ngFactoryFn`, instead of the usual `factory` property in their respective defs. This should eventually allow us to inject any kind of decorated class (e.g. a pipe).

**Note:** these changes are the first part of the refactor and they don't include injectables. I decided to leave injectables for a follow-up PR, because there's some more cases we need to handle when it comes to their factories. Furthermore, directives, components and pipes make up most of the compiler output tests that need to be refactored and it'll make follow-up PRs easier to review if the tests are cleaned up now.

This is part of the larger refactor for FW-1468.

Kara Erickson de8ebbdfd0 feat(ivy): make Hammer support tree-shakable (#32203)
Currently, it's not possible to tree-shake away the
coordination layer between HammerJS and Angular's
EventManager. This means that you get the HammerJS
support code in your production bundle whether or
not you actually use the library.

This commit removes the Hammer providers from the
default platform_browser providers list and instead
provides them as part of a `HammerModule`. Apps on
Ivy just need to import the `HammerModule` at root
to turn on Hammer support. Otherwise all Hammer code
will tree-shake away. View Engine apps will require
no change.

BREAKING CHANGE

Previously, in Ivy applications, Hammer providers
were included by default. With this commit, apps
that want Hammer support must import `HammerModule`
in their root module.

Miško Hevery 2e4d17f3a9 perf(core): make sanitization tree-shakable in Ivy mode (#31934)
In VE the `Sanitizer` is always available in `BrowserModule` because the VE retrieves it using injection.

In Ivy the injection is optional and we have instructions instead of component definition arrays. The implication of this is that in Ivy the instructions can pull in the sanitizer only when they are working with a property which is known to be unsafe. Because the Injection is optional this works even if no Sanitizer is present. So in Ivy we first use the sanitizer which is pulled in by the instruction, unless one is available through the `Injector` then we use that one instead.

This PR does few things:
1) It makes `Sanitizer` optional in Ivy.
2) It makes `DomSanitizer` tree shakable.
3) It aligns the semantics of Ivy `Sanitizer` with that of the Ivy sanitization rules.
4) It refactors `DomSanitizer` to use same functions as Ivy sanitization for consistency.

Alex Rickabaugh 4055150910 feat(compiler): allow selector-less directives as base classes (#31379)
In Angular today, the following pattern works:

```typescript
export class BaseDir {
  constructor(@Inject(ViewContainerRef) protected vcr: ViewContainerRef) {}
}

@Directive({
  selector: '[child]',
})
export class ChildDir extends BaseDir {
  // constructor inherited from BaseDir
}
```

A decorated child class can inherit a constructor from an undecorated base
class, so long as the base class has metadata of its own (for JIT mode).
This pattern works regardless of metadata in AOT.

In Angular Ivy, this pattern does not work: without the @Directive
annotation identifying the base class as a directive, information about its
constructor parameters will not be captured by the Ivy compiler. This is a
result of Ivy's locality principle, which is the basis behind a number of
compilation optimizations.

As a solution, @Directive() without a selector will be interpreted as a
"directive base class" annotation. Such a directive cannot be declared in an
NgModule, but can be inherited from. To implement this, a few changes are
made to the ngc compiler:

* the error for a selector-less directive is now generated when an NgModule
  declaring it is processed, not when the directive itself is processed.
* selector-less directives are not tracked along with other directives in
  the compiler, preventing other errors (like their absence in an NgModule)
  from being generated from them.

cexbrayat 628b0c1154 feat(forms): formControlName also accepts a number (#30606)
This commit relaxes the type of the `formControlName` input to accept both a `string` and a `number`.

Currently, when using a `FormArray`, most templates look like:

```
<div formArrayName="tags">
  <div *ngFor="let tag of tagsArray.controls; index as i">
    <input [formControlName]="i">
  </div>
</div>
```

Here `formControlName` receives a number whereas its input type is a string.

This is fine for VE and `fullTemplateTypeCheck`, but not for Ivy which does a more thorough type checking on inputs with `fullTemplateTypeCheck` enabled and throws `Type 'number' is not assignable to type 'string'`. It is fixable by using `formControlName="{{i}}"` but you have to know the difference between `a="{{b}}"` and `[a]="b"` and change it all over the application codebase. This commit allows the existing code to still type-check.

crisbeto 0aff4a6919 fix(ivy): incorrect ChangeDetectorRef injected into pipes used in component inputs (#31438)
When injecting a `ChangeDetectorRef` into a pipe, the expected result is that the ref will be tied to the component in which the pipe is being used. This works for most cases, however when a pipe is used inside a property binding of a component (see test case as an example), the current `TNode` is pointing to component's host so we end up injecting the inner component's view. These changes fix the issue by only looking up the component view of the `TNode` if the `TNode` is a parent.

Paul Gschwendtner 10a1e1974b fix(platform-browser): debug element query predicates not compatible with strictFunctionTypes (#30993)
Currently developers can use the `By` class to construct common
`DebugElement` query predicates. e.g. `By.directive(MyDirective)`.

The `directive()` and `all()` predicates are currently returning
a predicate that works for `DebugElement` nodes. This return type
is too strict since the predicate is not specific to `DebugElement`
instances and can also apply to `DebugNode` instances.

Meaning that developers are currently able to use the `directive()`
predicate when using `queryAllNodes()`. This is a common practice
but will break when the project is compiled with TypeScript's
`--strictFunctionTypes` flag as the `DebugElement` predicate type
is not assignable to predicates for `DebugNode`. In order to make
these predicates usable with `--strictFuntionTypes` enabled, we
adjust the predicate type to reflect what is actually needed for
evaluation of the predicate.

crisbeto 40d785f0a0 perf(ivy): avoid generating extra parameters for host property bindings (#31550)
Currently we reuse the same instruction both for regular property bindings and property bindings on the `host`. The only difference between the two is that when it's on the host we shouldn't support inputs. We have an optional parameter called `nativeOnly` which is used to differentiate the two, however since `nativeOnly` is preceeded by another optional parameter (`sanitizer`), we have to generate two extra parameters for each host property bindings every time (e.g. `property('someProp', 'someValue', null, true)`).

These changes add a new instruction called `hostProperty` which avoids the need for the two parameters by removing `nativeOnly` which is always set and it allows us to omit `sanitizer` when it isn't being used.

These changes also remove the `nativeOnly` parameter from the `updateSyntheticHostBinding` instruction, because it's only generated for host elements which means that we can assume that its value will always be `true`.

Adds the new `classMapInterpolate1` through `classMapInterpolate8` instructions which handle interpolations inside the `class` attribute and moves the interpolation logic internally. This allows us to remove the `interpolationX` instructions in a follow-up PR.

Up until now this would actually generate valid instructions, because `styleMap` goes through the same code path as `classMap` which does support interpolation. At runtime, however, `styleMap` would set invalid styles that look like `<div style="0:w;1:i;2:d;3:t;4:h;5::;7:1;">`.

Paul Gschwendtner aca339e864 fix(ivy): unable to project into multiple slots with default selector (#30561)
With View engine it was possible to declare multiple projection
definitions and to programmatically project nodes into the slots.

e.g.

```html
<ng-content></ng-content>
<ng-content></ng-content>
```

Using `ViewContainerRef#createComponent` allowed projecting
nodes into one of the projection defs (through index)

This no longer works with Ivy as the `projectionDef` instruction only
retrieves a list of selectors instead of also retrieving entries for
reserved projection slots which appear when using the default
selector multiple times (as seen above).

In order to fix this issue, the Ivy compiler now passes all
projection slots to the `projectionDef` instruction. Meaning that
there can be multiple projection slots with the same wildcard
selector. This allows multi-slot projection as seen in the
example above, and it also allows us to match the multi-slot node
projection order from View Engine (to avoid breaking changes).

It basically ensures that Ivy fully matches the View Engine behavior
except of a very small edge case that has already been discussed
in FW-886 (with the conclusion of working as intended).

Olivier Combe 5e0f982961 feat(ivy): use i18n locale data to determine the plural form of ICU expressions (#29249)
Plural ICU expressions depend on the locale (different languages have different plural forms). Until now the locale was hard coded as `en-US`.
For compatibility reasons, if you use ivy with AOT and bootstrap your app with `bootstrapModule` then the `LOCALE_ID` token will be set automatically for ivy, which is then used to get the correct plural form.
If you use JIT, you need to define the `LOCALE_ID` provider on the module that you bootstrap.
For `TestBed` you can use either `configureTestingModule` or `overrideProvider` to define that provider.
If you don't use the compat mode and start your app with `renderComponent` you need to call `ɵsetLocaleId` manually to define the `LOCALE_ID` before bootstrap. We expect this to change once we start adding the new i18n APIs, so don't rely on this function (there's a reason why it's a private export).

Alex Rickabaugh 84dd2679a9 fix(core): require 'static' flag on queries in typings (#30639)
This commit makes the static flag on @ViewChild and @ContentChild required.

BREAKING CHANGE:

In Angular version 8, it's required that all @ViewChild and @ContentChild
queries have a 'static' flag specifying whether the query is 'static' or
'dynamic'. The compiler previously sorted queries automatically, but in
8.0 developers are required to explicitly specify which behavior is wanted.
This is a temporary requirement as part of a migration; see
https://angular.io/guide/static-query-migration for more details.

@ViewChildren and @ContentChildren queries are always dynamic, and so are
unaffected.

Alex Rickabaugh ccc76f7498 feat(platform-webworker): deprecate platform-webworker (#30642)
DEPRECATION:

platform-webworker has been around since the initial release of Angular
version 2. It began as an experiment to leverage Angular's rendering
architecture and try something different: to run an entire web application
in a web worker.

We've learned a lot from this experiment, and have come to the conclusion
that pushing entire applications to run in a web worker is not a recipe for
success for most applications. This is due to a number of unresolved issues,
including:

* Poor or non-existent support for web worker APIs in web crawlers/indexers.
* Poor support in build and bundling tooling.

As a result, as of Angular version 8, we are deprecating the
`platform-webworker` APIs in Angular. This consists of both NPM packages,
`@angular/platform-webworker` and `@angular/platform-webworker-dynamic`.

Going forward, we will focus our efforts related to web workers around their
primary use case of offloading CPU-intensive but not critical work.

Kara Erickson a96976e88f fix(core): remove deprecated `TestBed.deprecatedOverrideProvider` API (#30576)
BREAKING CHANGE

In PR #19558, we fixed a bug in `TestBed.overrideProvider` where
eager providers were not being instantiated correctly. However,
it turned out that since this bug had been around for quite a bit,
many apps were relying on the broken behavior where the providers
would not be instantiated. To assist in the transition, the
`TestBed.deprecatedOverrideProvider` method was temporarily
introduced to mimic the old behavior so that apps would have a
longer time period to migrate their code.

2 years and 3 versions later, it is time to remove the temporary
method. This commit removes `TestBed.deprecatedOverrideProvider`
altogether. Any usages of `TestBed.deprecatedOverrideProvider`
should be replaced with `TestBed.overrideProvider`. This may mean
that providers that were not created before will now be instantiated,
which could mean that your tests need to provide more mocks or stubs
for the dependencies of the newly instantiated providers.

cexbrayat 95830ee584 feat(common): stricter types for SlicePipe (#30156)
Adds overloads to the `transform` methods of `SlicePipe`,
to have better types than `any` for `value` and `any` as a return.
With this commit, using `slice` in an `ngFor` still allow to type-check the content of the `ngFor`
with `fullTemplateTypeCheck` enabled in Ivy:

    <div *ngFor="let user of users | slice:0:2">{{ user.typo }}</div>
                                                        |
                                                        `typo` does not exist on type `UserModel`

whereas it is currently not catched (as the return of `slice` is `any`) neither in VE nor in Ivy.

BREAKING CHANGE
`SlicePipe` now only accepts an array of values, a string, null or undefined.
This was already the case in practice, and it still throws at runtime if another type is given.
But it is now a compilation error to try to call it with an unsupported type.

JoostK e9ead2bc09 feat(ivy): more accurate type narrowing for `ngIf` directive (#30248)
A structural directive can specify a template guard for an input, such that
the type of that input's binding can be narrowed based on the guard's return
type. Previously, such template guards could only be methods, of which an
invocation would be inserted into the type-check block (TCB). For `NgIf`,
the template guard narrowed the type of its expression to be `NonNullable`
using the following declaration:

```typescript
export declare class NgIf {
  static ngTemplateGuard_ngIf<E>(dir: NgIf, expr: E): expr is NonNullable<E>
}
```

This works fine for usages such as `*ngIf="person"` but starts to introduce
false-positives when e.g. an explicit non-null check like
`*ngIf="person !== null"` is used, as the method invocation in the TCB
would not have the desired effect of narrowing `person` to become
non-nullable:

```typescript
if (NgIf.ngTemplateGuard_ngIf(directive, ctx.person !== null)) {
  // Usages of `ctx.person` within this block would
  // not have been narrowed to be non-nullable.
}
```

This commit introduces a new strategy for template guards to allow for the
binding expression itself to be used as template guard in the TCB. Now,
the TCB generated for `*ngIf="person !== null"` would look as follows:

```typescript
if (ctx.person !== null) {
  // This time `ctx.person` will successfully have
  // been narrowed to be non-nullable.
}
```

This strategy can be activated by declaring the template guard as a
property declaration with `'binding'` as literal return type.

See #30235 for an example where this led to a false positive.

Alex Rickabaugh c61df39323 feat(router): deprecate loadChildren:string (#30073)
The proposed ES dynamic import() is now supported by the Angular CLI and the
larger toolchain. This renders the `loadChildren: string` API largely
redundant, as import() is far more natural, is less error-prone, and is
standards compliant. This commit deprecates the `string` form of
`loadChildren` in favor of dynamic import().

DEPRECATION:

When defining lazy-loaded route, Angular previously offered two options for
configuring the module to be loaded, both via the `loadChildren` parameter
of the route. Most Angular developers are familiar withthe `string` form of
this API. For example, the following route definition configures Angular to
load a `LazyModule` NgModule from `lazy-route/lazy.module.ts`:

```
[{
  path: 'lazy',
  loadChildren: 'lazy-route/lazy.module#LazyModule',
}]
```

This "magic string" configuration was previously necessary as there was
no dynamic module loading standard on the web. This has changed with the
pending standardization of dynamic `import()` expressions, which are now
supported in the Angular CLI and in web tooling in general. `import()`
offers a more natural and robust solution to dynamic module loading. The
above example can be rewritten to use dynamic `import()`:

```
[{
  path: 'lazy',
  loadChildren: () => import('./lazy-route/lazy.module').then(mod => mod.LazyModule),
}]
```

This form of lazy loading offers significant advantages in terms of:

* type checking via TypeScript
* simplicity of generated code
* future potential to run natively in supporting browsers
  (see: [caniuse: dynamic import()](https://caniuse.com/#feat=es6-module-dynamic-import))

As a result, Angular is deprecating the `loadChildren: string` syntax in
favor of ES dynamic `import()`. An automatic migration will run during
`ng upgrade` to convert your existing Angular code to the new syntax.

Jason Aden 4277600d5e feat(common): provide replacement for AngularJS $location service (#30055)
This commit provides a replacement for `$location`. The new service is written in Angular, and can be consumed into existing applications by using the downgraded version
of the provider.

Prior to this addition, applications upgrading from AngularJS to Angular could get into a situation where AngularJS wanted to control the URL, and would often parse or se
rialize the URL in a different way than Angular. Additionally, AngularJS was alerted to URL changes only through the `$digest` cycle. This provided a buggy feedback loop
from Angular to AngularJS.

With this new `LocationUpgradeProvider`, the `$location` methods and events are provided in Angular, and use Angular APIs to make updates to the URL. Additionally, change
s to the URL made by other parts of the Angular framework (such as the Router) will be listened for and will cause events to fire in AngularJS, but will no longer attempt
 to update the URL (since it was already updated by the Angular framework).

This centralizes URL reads and writes to Angular and should help provide an easier path to upgrading AngularJS applications to Angular.

This meant if you weren't using the Angular router, there wasn't a way to get access to this `history.state` value other than going directly to the DOM.

This PR adds an API to retrieve the value of `history.state`. This will be useful and needed to provide a backwards-compatible `Location` service that can emulate AngularJS's `$location` service since we will need to be able to read the state data in order to produce AngularJS location transition events.

This feature will additionally be useful to any application that wants to access state data through Angular rather than going directly to the DOM APIs.

Plural ICU expressions depend on the locale (different languages have different plural forms). Until now the locale was hard coded as `en-US`.
For compatibility reasons, if you use ivy with AOT and bootstrap your app with `bootstrapModule` then the `LOCALE_ID` token will be set automatically for ivy, which is then used to get the correct plural form.
If you use JIT, you need to define the `LOCALE_ID` provider on the module that you bootstrap.
For `TestBed` you can use either `configureTestingModule` or `overrideProvider` to define that provider.
If you don't use the compat mode and start your app with `renderComponent` you need to call `ɵsetLocaleId` manually to define the `LOCALE_ID` before bootstrap. We expect this to change once we start adding the new i18n APIs, so don't rely on this function (there's a reason why it's a private export).

These changes rework the compiler not to output the raw selectors in the projectionDef, but to parse the selector in ngProjectAs and to store it on the TAttributes.

by symlinking the `src` folder, which allowed both packages to access
the upgrade/common files.

These symlinks are always problematic on Windows, where we had to run
a script to re-link them, and restore them.

This change uses Bazel packages to share the `upgrade/common` code,
which avoids the need for symlinking the `src` folder.

Also, the Windows specific scripts that fixup the symlinks have also
been removed as there is no more need for them.
