What is the current behavior?
The language service access TypeScript's Symbol.members without checking for null or undefined.
What is the new behavior?
The access is guarded.

Updated example to illustrate @ContentChildren default behavior (only query direct children), and how to query for nested elements/all descendants.
This has the side effect of allowing `@Input` and `@ContentChild`
on the same property if the query is static (see the bug description
for details).

To generate XLF files with ng-xi18n we could use the format parameter "xlf" or "xlif". The real name is "xliff" not "xlif", so this probably was a typo. This PR adds "xliff" as can be expected
`ngc` would look for flat module resources relative to the flat module index.
`ngc` now looks for flat module resources relative to the `.d.ts` file that declarates
the component.

This commit fixes a regression where `ngModel` no longer syncs
letter by letter on Android devices, and instead syncs at the
end of every word. This broke when we introduced buffering of
IME events so IMEs like Pinyin keyboards or Katakana keyboards
wouldn't display composition strings. Unfortunately, iOS devices
and Android devices have opposite event behavior. Whereas iOS
devices fire composition events for IME keyboards only, Android
fires composition events for Latin-language keyboards. For
this reason, languages like English don't work as expected on
Android if we always buffer. So to support both platforms,
composition string buffering will only be turned on by default
for non-Android devices.
However, we have also added a `COMPOSITION_BUFFER_MODE` token
to make this configurable by the application. In some cases, apps
might might still want to receive intermediate values. For example,
some inputs begin searching based on Latin letters before a
character selection is made.
As a provider, this is fairly flexible. If you want to turn
composition buffering off, simply provide the token at the top
level:
```ts
providers: [
{provide: COMPOSITION_BUFFER_MODE, useValue: false}
]
```
Or, if you want to change the mode based on locale or platform,
you can use a factory:
```ts
import {shouldUseBuffering} from 'my/lib';
....
providers: [
{provide: COMPOSITION_BUFFER_MODE, useFactory: shouldUseBuffering}
]
```

Unlike in the browser, on the server there is no concept of a document origin.
Thus, it is illegal to make requests for relative URLs against Http on platform-server.
Currently this fails with a vague error:
Error: Uncaught (in promise): Error at resolvePromise
This change adds explicit validation and a friendlier error message:
Error: URLs requested via Http on the server must be absolute. URL: /testing
Another option considered was to track the concept of an origin for the platform
and automatically prepend it to relative URLs. This would cause automatic "local
RPCs" to be made, though, which would be an unexpected and undesirable default
behavior.

This change reduces the amount of generated code by only adding `log`
calls for elements and text nodes.
We need the `log` calls to allow users to jump to the right place
in the template via source maps. However, we only need it for element
and text nodes, but not for directives, queries, … as for them we
first locate the corresponding element or text node.

This is needed to support the corner cases:
- usage of a `ComponentFactory` that was created on the fly via `Compiler`
- overwriting of the `NgModuleRef` that is associated to a
`ComponentFactory` by the `ComponentFactoryResolver` from
which it was read.

The Router use the type `Params` for all of:
- position parameters,
- matrix parameters,
- query parameters.
`Params` is defined as follow `type Params = {[key: string]: any}`
Because parameters can either have single or multiple values, the type should
actually be `type Params = {[key: string]: string | string[]}`.
The client code often assumes that parameters have single values, as in the
following exemple:
```
class MyComponent {
sessionId: Observable<string>;
constructor(private route: ActivatedRoute) {}
ngOnInit() {
this.sessionId = this.route
.queryParams
.map(params => params['session_id'] || 'None');
}
}
```
The problem here is that `params['session_id']` could be `string` or `string[]`
but the error is not caught at build time because of the `any` type.
Fixing the type as describe above would break the build because `sessionId`
would becomes an `Observable<string | string[]>`.
However the client code knows if it expects a single or multiple values. By
using the new `ParamMap` interface the user code can decide when it needs a
single value (calling `ParamMap.get(): string`) or multiple values (calling
`ParamMap.getAll(): string[]`).
The above exemple should be rewritten as:
```
class MyComponent {
sessionId: Observable<string>;
constructor(private route: ActivatedRoute) {}
ngOnInit() {
this.sessionId = this.route
.queryParamMap
.map(paramMap => paramMap.get('session_id') || 'None');
}
}
```
Added APIs:
- `interface ParamMap`,
- `ActivatedRoute.paramMap: ParamMap`,
- `ActivatedRoute.queryParamMap: ParamMap`,
- `ActivatedRouteSnapshot.paramMap: ParamMap`,
- `ActivatedRouteSnapshot.queryParamMap: ParamMap`,
- `UrlSegment.parameterMap: ParamMap`
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.

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.
