Before this PR there were only 2 zones: root zone = outer zone > inner
zone.
This PR creates the outer zone as a fork of the root zone: root > outer
> inner.
By doing this it is possible to detected microtasks scheduling in the
outer zone and run the change detection less often (no more than one
time per VM turn).
The PR also introduce a Promise monkey patch for the JS implementation.
It makes Promises aware of microtasks and again allow running the change
detection only once per turn.
The async pipe in templates will now delegate to both Observable pipe or Promise pipe,
whichever first says it can support the input. Therefore, it's beneficial to disambiguate
the name of the AsyncPipe/AsyncPipeFactory constructors to reflect that these actually
support only Observables.
Update the `TemplateCompile` step to use the full render `Compiler`.
Provide `DirectiveMetadata` for `ViewDefinition` objects and use it to
run the `DirectiveParser` step of the render compile pipeline.
The goal is to make implementing a renderer straight forward.
BREAKING_CHANGE:
- Renderer interface was redone / simplified.
- `DirectDomRenderer` was replaced by `DomRenderer`.
- `DirectDomRenderer.setImperativeComponentRootNodes` is replaced
by the following 2 steps:
1. `ViewManager.getComponentView(elementRef) -> ViewRef`
2. `DomRenderer.setComponentViewRootNodes(viewRef, rootNodes)`
- all `@View` annotations need to have a template, but the template
may be empty. Previously views that had a `renderer` property did
not have to have a `template`.
- `dynamicComponentLoader.loadIntoNewLocation` does no more allow
to pass an element, but requires a css selector.
Special syntax: `:document` can be used as prefix to search globally
on the document instead of in the provided parent view.
Part of #1675
Using string1 === string2 translates to identical(string1, string2) in
dart, which is incorrect as it is possilbe for dart strings to have
different reference.
Add a step that reads `DirectiveMetadata` object off annotated classes
into `.ng_meta.dart` files. These will be used by the `TemplateCompiler`
step as inputs to the Angular 2 render compiler.
Update one test to avoid unsupported functionality, format others.
In 'angular2/di' the symbol:
- Inject is a decorator
- InjectAnnotation is an annotation
Internally one an get a hold of annotations without *Annotations appened
(to make ts2dart work without workarounds) by importing from
'angular2/src/di/annotations_impl' instead of 'angular2/di'. This is
needed only for users that transpile through TS and through ts2dart.
This removes .es6 files which are pure duplicates of a
.ts file in the same folder.
Next we need to remove .js files as well, and remove karma preprocessors for dart.
