BREAKING CHANGE:
Previously, pipes that wanted to be notified when they were destroyed
would implement the PipeOnDestroy interface and name the callback
`onDestroy`. This change removes the PipeOnDestroy interface and
instead uses Angular's lifecycle interface `OnDestroy`, with the
`ngOnDestroy` method.
Before:
```
import {Pipe, PipeOnDestroy} from 'angular2/angular2';
@Pipe({pure: false})
export class MyPipe implements PipeOnDestroy {
onDestroy() {}
}
```
After:
import {Pipe, OnDestroy} from 'angular2/angular2';
@Pipe({pure: false})
export class MyPipe implements PipeOnDestroy {
ngOnDestroy() {}
}
BREAKING CHANGE:
Previously, components that would implement lifecycle interfaces would include methods
like "onChanges" or "afterViewInit." Given that components were at risk of using such
names without realizing that Angular would call the methods at different points of
the component lifecycle. This change adds an "ng" prefix to all lifecycle hook methods,
far reducing the risk of an accidental name collision.
To fix, just rename these methods:
* onInit
* onDestroy
* doCheck
* onChanges
* afterContentInit
* afterContentChecked
* afterViewInit
* afterViewChecked
* _Router Hooks_
* onActivate
* onReuse
* onDeactivate
* canReuse
* canDeactivate
To:
* ngOnInit,
* ngOnDestroy,
* ngDoCheck,
* ngOnChanges,
* ngAfterContentInit,
* ngAfterContentChecked,
* ngAfterViewInit,
* ngAfterViewChecked
* _Router Hooks_
* routerOnActivate
* routerOnReuse
* routerOnDeactivate
* routerCanReuse
* routerCanDeactivate
The names of lifecycle interfaces and enums have not changed, though interfaces
have been updated to reflect the new method names.

Use a zone counting timeouts and microtasks to determine when a test
is finished, instead of requiring the test writer to use
injectAsync and return a promise.
See #5322
This is a big change. @matsko also deserves much of the credit for the implementation.
Previously, `ComponentInstruction`s held all the state for async components.
Now, we introduce several subclasses for `Instruction` to describe each type of navigation.
BREAKING CHANGE:
Redirects now use the Link DSL syntax. Before:
```
@RouteConfig([
{ path: '/foo', redirectTo: '/bar' },
{ path: '/bar', component: BarCmp }
])
```
After:
```
@RouteConfig([
{ path: '/foo', redirectTo: ['Bar'] },
{ path: '/bar', component: BarCmp, name: 'Bar' }
])
```
BREAKING CHANGE:
This also introduces `useAsDefault` in the RouteConfig, which makes cases like lazy-loading
and encapsulating large routes with sub-routes easier.
Previously, you could use `redirectTo` like this to expand a URL like `/tab` to `/tab/posts`:
@RouteConfig([
{ path: '/tab', redirectTo: '/tab/users' }
{ path: '/tab', component: TabsCmp, name: 'Tab' }
])
AppCmp { ... }
Now the recommended way to handle this is case is to use `useAsDefault` like so:
```
@RouteConfig([
{ path: '/tab', component: TabsCmp, name: 'Tab' }
])
AppCmp { ... }
@RouteConfig([
{ path: '/posts', component: PostsCmp, useAsDefault: true, name: 'Posts' },
{ path: '/users', component: UsersCmp, name: 'Users' }
])
TabsCmp { ... }
```
In the above example, you can write just `['/Tab']` and the route `Users` is automatically selected as a child route.

A quoted expression is:
quoted expression = prefix `:` uninterpretedExpression
prefix = identifier
uninterpretedExpression = arbitrary string
Example: "route:/some/route"
Quoted expressions are parsed into a new AST node type Quote. The `prefix` part of the
node must be a legal identifier. The `uninterpretedExpression` part of the node is an
arbitrary string that Angular does not interpret.
This feature is meant to be used together with template AST transformers introduced in
a43ed79ee7. The
transformer would interpret the quoted expression and convert it into a standard AST no
longer containing quoted expressions. Angular will continue compiling the resulting AST
normally.

Often some init logic needs to run when a platform or an application is boostrapped.
For example, boostraping a platform requires initializing the dom adapter.
Now, it can be done as follows:
new Provider(PLATFORM_INITIALIZER, {useValue: initDomAdapter, multi: true}),
All platform initializers will be run after the platform injector has been created.
Similarly, all application initializers will be run after the app injector has been
created.
Closes#5355
Currently, core depends on DomRenderer, which depends on the browser.
This means that if you depend on angular2/core, you will always
pull in the browser dom adapter and the browser render, regardless
if you need them or not.
This PR moves the browser dom adapter and the browser renderer out of core.
BREAKING CHANGE
If you import browser adapter or dom renderer directly (not via angular2/core),
you will have to change the import path.
Currently, core depends on the browser, which means that other platforms (e.g., NativeScript or webworker) cannot use the bootstrapping logic core provides.
This PR extract makes bootstrapping logic in core completely platform-independent. The browser-specific code was moved to "angular2/platforms/browser".
BREAKING CHANGE
A few private helpers (e.g., platformCommon or applicationCommon) were removed or replaced with other helpers. Look at PLATFORM_COMMON_PROVIDERS, APPLICATION_COMMON_PROVIDERS, BROWSER_PROVIDERS, BROWSER_APP_PROVIDERS to see if they export the providers you need.

BREAKING CHANGE
Previously, the controlsErrors getter of ControlGroup and ControlArray returned the errors of their direct children. This was confusing because the result did not include the errors of nested children (ControlGroup -> ControlGroup -> Control). Making controlsErrors to include such errors would require inventing some custom serialization format, which applications would have to understand.
Since controlsErrors was just a convenience method, and it was causing confusing, we are removing it. If you want to get the errors of the whole form serialized into a single object, you can manually traverse the form and accumulate the errors. This way you have more control over how the errors are serialized.

Ambient directives can be configured when bootstraping an application.
Ambient directives can be used in every component of the application without
needing to explicitly list them.
- Changes the `alreadyChecked` flag of AbstractChangeDetector to a new `state` flag.
- Changes all checks of alreadyChecked to check that the state is NeverChecked.
- Set state to Errored if an error is thrown during detection.
- Skip change detection for a detector and its children when the state is Errored.
- Add a test to validate this fixes issue #4323.

Refactor EventEmitter and Async Facade to match ES7 Observable semantics, properly use RxJS typedefs, make EventEmitter inherit from RxJS Subject. Closes#4149.
BREAKING CHANGE:
- consumers of EventEmitter no longer need to call .toRx()
- EventEmitter is now generic and requires a type - e.g. `EventEmitter<string>`
- EventEmitter and Observable now use the `.subscribe(generatorOrNext, error, complete)` method instead of `.observer(generator)`
- ObservableWrapper uses `callNext/callError/callComplete` instead of `callNext/callThrow/callReturn`
We used to use different external css parsers,
depending on the `DomAdapter`. This lead to
inconsistent behavior and environment specific errors.
Closes#5006Closes#4993
Currently, the only way for a directive to export a validator is by providing a function. This makes it ackward to write validators that depend on directive inputs. In addition to supporting functions as validators, classes implementing the Validator interface are supported too.
- fixes wrapping for object literal keys called `template`.
- spacing in destructuring expressions.
- changes to keep trailing return types of functions closer to their
function declaration.
- better formatting of string literals.
Closes#4828
Example:
var login = new Control("someLogin");
c.setErrors({"notUnique": true});
expect(c.valid).toEqual(false);
expect(c.errors).toEqual({"notUnique": true});
c.updateValue("newLogin");
expect(c.valid).toEqual(true);
BREAKING CHANGE:
Before:
ControlGroup.errors and ControlArray.errors returned a reduced value of their children controls' errors.

ControlGroup.errors and ControlArray.errors return the errors of the group and array.
And ControlGroup.controlsErrors and ControlArray.controlsErrors return the reduce value of their children controls' errors.

The ROUTE_DATA token has been removed and replaced with a type RouteData,
allowing a type injection like we do with RouteParams.

constructor(routeParams: RouteParams, @Inject(ROUTE_DATA) routeData) {
let id = routeParams.get('id');
let name = ROUTE_DATA.name;

Allow ControlGroups and ControlArrays to contain errors from their level, and
errors from their children. [Design Doc](https://docs.google.com/document/d/1EnJ3-_iFpVKFz1ifN1LkXSGQ7h3A72OQGry2g8eo7IA/edit?pli=1#heading=h.j53rt81eegm4)
BREAKING CHANGE: errors format has changed from validators. Now errors from
a control or an array's children are prefixed with 'controls' while errors
from the object itself are left at the root level.
Example:
Given a Control group as follows:
var group = new ControlGroup({
login: new Control("", required),
password: new Control("", required),
passwordConfirm: new Control("", required)
});
Before:
group.errors
{
login: {required: true},
password: {required: true},

}
After:
group.errors
{
controls: {
login: {required: true},
password: {required: true},
passwordConfirm: {required: true},
}
}
BREAKING CHANGES:
- deprecates these methods in NgZone: overrideOnTurnStart, overrideOnTurnDone, overrideOnEventDone, overrideOnErrorHandler
- introduces new API in NgZone that may shadow other API used by existing applications.
BREAKING CHANGES:
- you can no longer use a #foo or a var-foo to apply directive [foo], although
it didn't work properly anyway.
This commit is fixing breakage caused by the switch to pre-compiler (exact SHA
unknown).
The test injector now uses an XHR implementation based on DOM.getXHR,
which allows the current DOM adapter to dictate which XHR impl should
be used.
To prevent the changes to DOM adapter from introducing undesired new
dependencies into the benchmarks, separate the async facade into
a promise facade which is reexported by facade/async.
See #4539
We can’t resolve relative urls (e.g. for images) in the compiler as
these urls are meant to be loaded in the browser
(unless we would inline images as base64…).
Also, keep `<link rel=“stylesheet”>` in templates that
reference absolute urls with e.g. `http://`. This
behavior was already present for `@import` rules
within stylesheets.
Closes#4740
Adds test adapters for TypeScript and JavaScript only, exported
as part of the test_lib module. These work with the Jasmine test
framework, and allow use of the test injector within test blocks
via the `inject` function.
See #4572, #4177, #4035, #2783
This includes the TestComponentBuilder. It allows using the
test injector with Jasmine bindings, and waits for returned
promises before completing async test blocks.
This is useful for the compiler tests, but otherwise it's not useful.
Additionally if an application has external templates (as is common) then
we should actually fetch these templates in tests.

This was a poorly typed attempt to mimic TypeScript's index signatures,
which we can use instead.
This eliminates a very strange type that we were exposing to users, but
not re-exporting through our public API.
Fixes#4483
BREAKING CHANGE:
- Removes `ChangeDetection`, use a binding for `ChangeDetectorGenConfig` instead
to configure change detection.
- `RenderElementRef.renderBoundElementIndex` was renamed to `RenderElementRef.boundElementIndex`.
- Removes `ViewLoader`, use `XHRImpl` instead.
Closes#3605
BREAKING CHANGE:
- we don't mark an element as bound any more if it only contains text bindings
E.g. <div>{{hello}}</div>
This changes the indices when using `DebugElement.componentViewChildren` / `DebugElement.children`.
- `@Directive.compileChildren` was removed,
`ng-non-bindable` is now builtin and not a directive any more
- angular no more adds the `ng-binding` class to elements with bindings
- directives are now ordered as they are listed in the View.directives regarding change detection.
Previously they had an undefined order.
- the `Renderer` interface has new methods `createProtoView` and `registerComponentTemplate`. See `DomRenderer` for default implementations.
- reprojection with `ng-content` is now all or nothing per `ng-content` element
- angular2 transformer can't be used in tests that modify directive metadata.
Use `angular2/src/transform/inliner_for_test` transformer instead.
The output of the compiler has to be the same
given the same input. Requiring a unique id for
every type already during compilation makes it
hard to parallelize compilation.

- handle `ng-non-bindable` correctly
- add some more assertions to `TemplateCompiler`
- make `CompiledTemplate` const
- fix default value for `@Directive.moduleId`
- add new compiler to application bindings
BREAKING CHANGE:
- `Compiler.compileInHost` and all methods of `DynamicComponentLoader` don’t take `Binding` any more, only `Type`s. This is in preparation for the new compiler which does not support this.
Part of #3605Closes#4346
BREAKING CHANGE:
It's unlikely that any apps were explicitly referencing `RootRouter`, but if they were they should
prefer to use the `routerBindings` helper or the `ROUTER_BINDINGS` const exported from `angular2/router`
- Rename `DirectiveMetadata` into `CompileDirectiveMetadata`, merge
with `NormalizedDirectiveMetadata` and remove `ChangeDetectionMetadata`
- Store change detector factories not as array but
directly at the `CompiledTemplate` or the embedded template
to make instantiation easier later on
- Already analyze variable values and map them
to `Directive.exportAs`
- Keep the directive sort order as specified in the
`@View()` annotation
- Allow to clear the runtime cache in `StyleCompiler`
and `TemplateCompiler`
- Ignore `script` elements to match the semantics of the
current compiler
- Make all components dynamically loadable and remove
the previously introduced property `@Component#dynamicLoadable`
for now until we find a better option to configure this
- Don’t allow to specify bindings in `@View#directives` and `@View#pipes` as this was never supported by the transformer (see below for the breaking change)
BREAKING CHANGE:
- don't support DI bindings in `@View#directives` and `@View@pipes` any more in preparation of integrating the new compiler. Use `@Directive#bindings` to reexport directives under a different token instead.

The debug tools used to take ApplicationRefs, which are the old return
type of bootstrap. Now bootstrap returns ComponentRef, so the debug
tools should be updated.
Closes#4203
This change adds a syntax for bootstrapping Angular on a page that allows more fine-grained control of the hierarchy created. platform() creates a platform injector (of which there can only be one). From the platform, .application() creates an Angular application including a Zone and all specified application bindings (e.g. for the DOM, HTTP, Compiler, Renderer, etc). At the application level, .bootstrap() will bootstrap the given component into that application.
Closes#3852
With the coming bootstrapping changes, a single application (and thus Router) can have multiple root components. One of these needs to be identified as the "primary" component from which the Router will load its configuration. This is now done by providing a ROUTER_PRIMARY_COMPONENT binding to the primary component type.
Previosly, recognition ended when a parent captured all the parsed URL segments.
This caused routes that delegated from a parent to a child with an empty segment
to never be recognized.
Closes#4178
Previously, `router.navigate` took a string representing the URL.
Now, it accepts an array that mirrors the link DSL.
Closes#4040
BREAKING CHANGE
The old method has been renamed to `router.navigateByUrl`.
Either change your navigation calls to use the DSL (preferred) or
call `router.navigateByUrl` instead.
Closes#4074
Previously, async routes generated from links would not load the configs of
their resolved components, which led to broken links in the children of the
async instruction's component.
This commit fixes the bookkeeping in the Router to correctly load the configs.

This change moves many APIs to the angular2/core export.
This change also automatically adds FORM_BINDINGS in
the application root injector.
BREAKING CHANGE:

APIs are now exported from angular2/core. Affected exports, which
should now be included from angular2/core include:
angular2/forms
angular2/di
angular2/directives
angular2/change_detection
angular2/bootstrap (except for dart users)
angular2/render
angular2/metadata
angular2/debug
angular2/pipes
Closes#3977
Instead of working with finer grained element injectors, queries now
iterate through the views as static units of modification of the
application structure. Views already contain element injectors in the
correct depth-first preorder.
This allows us to remove children linked lists on element injectors and a
lot of book keeping that is already present at the view level.
Queries are recalculated using the afterContentChecked and
afterViewChecked hooks, only during init and after a view container has
changed.
BREAKING CHANGE:
ViewQuery no longer supports the descendants flag. It queries the whole
component view by default.
