Previously, a pipe that returned a `WrappedValue` would force the change
of the next bound property, independent of the binding in which the pipe
was used.
Now only the binding in which the `WrappedValue` is used will be assumed
as changed.

This is so that server side rendering does not throw an exception when it encounters animations on the server side and does not need the user to explicitly setup NoopAnimationsModule in their app server module.
Fixes#15098, #14784.

Closure compiler is very sensitive to top level function calls.
This commit makes the function calls `createComponentFactory`
and `createRendererTypeV2` logic-less.

DEPRECATION:
- the arguments `inputs` / `outputs` / `ngContentSelectors` of `downgradeComponent`
are no longer used as Angular calculates these automatically now.
- Compiler.getNgContentSelectors is deprecated. Use
ComponentFactory.ngContentSelectors instead.
E.g. for a component like this:
```
@Component({
template: ‘<ng-content select=“child”></ng-content>’
})
class MyComp {
@Input(‘aInputName’)
aInputProp: string;
@Output(‘aEventName’)
aOuputProp: EventEmitter<any>;
}
```
the `ComponentFactory` will now contain the following:
- `inputs = {aInputProp: ‘aInputName’}`
- `outputs = {aOutputProp: ‘aOutputName’}`
- `ngContentSelectors = [‘child’]`
Fixes:
- In G3, filePaths don’t start with a `/` and therefore became relative.
- Always using the `ng://` prefix groups angular resources in the same
way for AOT and JIT.
ErrorHandler can not throw errors because it will unsubscribe itself from
the error stream.
Zones captures errors and feed it into NgZone, which than has a Rx Observable
to feed it into ErrorHandler. If the ErroHandler throws, then Rx will teardown
the observable which in essence causes the ErrorHandler to be removed from the
error handling. This implies that the ErrorHandler can never throw errors.
Closes#14949Closes#15182Closes#14316
Inlcuded fixes:
- include preamble in generated source map
- always add a mapping for line/col 0 so that the
generated sourcemap is not sparse
- use a uniue sourceUrl for inline templates even
in the AOT case
Observable subscriptions from previous validation runs should be canceled
before a new subscription is created for the next validation run.
Currently the subscription that sets the errors is canceled properly,
but the source observable created by the validator is not. While this
does not affect validation status or error setting, the source
observables will incorrectly continue through the pipeline until they
complete. This change ensures that the whole stream is canceled.
AsyncValidatorFn previously had an "any" return type, but now it more
explicitly requires a Promise or Observable return type. We don't
anticipate this causing problems given that any other return type
would have caused a runtime error already.
Previously, style values were parsed with a regex that split on /:+/.
This causes errors for CSS such as
div {
background-url: url(http://server.com/img.png);
}
since the regex would split the background-url line into 3 values instead of 2.
Now, the : character is detected with indexOf, avoiding this error.
A test was added to verify the behavior is correct.

* feat(common): support `as` syntax in template/* bindings
Closes#15020
Showing the new and the equivalent old syntax.
- `*ngIf="exp as var1”`
=> `*ngIf="exp; let var1 = ngIf”`
- `*ngFor="var item of itemsStream |async as items”`
=> `*ngFor="var item of itemsStream |async; let items = ngForOf”`
* feat(common): convert ngIf to use `*ngIf="exp as local“` syntax
* feat(common): convert ngForOf to use `*ngFor=“let i of exp as local“` syntax
* feat(common): expose NgForOfContext and NgIfContext
In v2.x, users had to annotate classes that they intended to use as tokens with `@Injectable`. This is no longer required in v4.x for tokens,
and we now require the constructor parameters of classes annotated
with `@Injectable` to be statically analyzable by ngc.
This commit reduces the error into a warning
if the constructor parameters do not meet this condition.
DEPRECATION:
- Classes annotated with `@Injectable` but whose constructor’s parameter types
are not statically analyzable by ngc will produce a warning.
Closes#15003
