Throwing an exception in a lifecycle event will delay but not
prevent an Init method, such as `ngOnInit`, `ngAfterContentInit`,
or `ngAfterViewInit`, from being called. Also, calling `detectChanges()`
in a way that causes duplicate change detection (such as a
child component causing a parent to call `detectChanges()` on its
own `ChangeDetectorRef`, will no longer prevent change `ngOnInit`,
`ngAfterContentInit` and `ngAfterViewInit` from being called.
With this change lifecycle methods are still not guarenteed to be
called but the Init methods will be called if at least one change
detection pass on its view is completed.

This allows to overwrite templates for JIT and AOT components alike.
In contrast to `TestBed.overrideTemplate`, the template is compiled
in the context of the testing module, allowing to use other testing
directives.
Closes#19815
Each node now has two index: nodeIndex and checkIndex.
nodeIndex is the index in both the view definition and the view data.
checkIndex is the index in in the update function (update directives and update
renderer).
While nodeIndex and checkIndex have the same value for now, having both of them
will allow changing the structure of view definition after compilation (ie for
runtime translations).
The private classes `ApplicationRef_`, `PlatformRef_`, `JSONPConnection_`, `JSONPBackend_`, `ClientMessageBrokerFactory_`, `ServiceMessageBroker_`, `ClientMessageBroker_` and `ServiceMessageBrokerFactory_` have been removed and merged into their public equivalents.
The size of the minified umd bundles have been slightly decreased:

Add testability hook to downgraded component so that protractor can wait for asynchronous call to complete.
Add unregisterApplication() and unregisterAllApplications() to testability registry for cleaning up testability and unit test.
BREAKING CHANGE: the compiler option `enableLegacyTemplate` is now disabled by default as the `<template>` element has been deprecated since v4. Use `<ng-template>` instead. The option `enableLegacyTemplate` and the `<template>` element will both be removed in Angular v6.

Prior to this fix if @parent and @child animations ran at the same
time within a disabled region then there was a chance that a @child
sub animation would never complete. This would cause *directives to
never close a removal when a @child trigger was placed on them. This
patch fixes this issue.

Prior to fix this fix, @.disabled would only work to disable child
animations. Now it will also disable animations for the element that has
the @.disabled flag (which makes more sense).

This change allows users to specify multiple exportAs names for a
directive by giving a comma-delimited list inside the string.
The primary motivation for this change is to allow these names to be
changed in a backwards compatible way.
toString() from DefaultIterableDiffer is only used in tests and should not
be part of the production code. toString() methods from differs add
~ 0.3KB (min+gzip) to the production bundle size.
BREAKING CHANGE
It is no longer possible to declare classes in this format.
```
Component({...}).
Class({
constructor: function() {...}
})
```
This format would only work with JIT and with ES5. This mode doesn’t
allow build tools like Webpack to process and optimize the code, which
results in prohibitively large bundles. We are removing this API
because we are trying to ensure that everyone is on the fast path by
default, and it is not possible to get on the fast path using the ES5
DSL. The replacement is to use TypeScript and `@Decorator` format.
```
@Component({...})
class {
constructor() {...}
}
```
This change allows ReflectiveInjector to be tree shaken resulting
in not needed Reflect polyfil and smaller bundles.
Code savings for HelloWorld using Closure:
Reflective: bundle.js: 105,864(34,190 gzip)
Static: bundle.js: 154,889(33,555 gzip)
645( 2%)
BREAKING CHANGE:
`platformXXXX()` no longer accepts providers which depend on reflection.
Specifically the method signature when from `Provider[]` to
`StaticProvider[]`.
Example:
Before:
```
[
MyClass,
{provide: ClassA, useClass: SubClassA}
]
```
After:
```
[
{provide: MyClass, deps: [Dep1,...]},
{provide: ClassA, useClass: SubClassA, deps: [Dep1,...]}
]
```
NOTE: This only applies to platform creation and providers for the JIT
compiler. It does not apply to `@Compotent` or `@NgModule` provides
declarations.
Benchpress note: Previously Benchpress also supported reflective
provides, which now require static providers.
DEPRECATION:
- `ReflectiveInjector` is now deprecated as it will be remove. Use
`Injector.create` as a replacement.

Angular can make many assumptions about its event handlers. As a result
the bookkeeping for native addEventListener is significantly cheaper
than Zone's addEventLister which can't make such assumptions.
This change bypasses the Zone's addEventListener if present and always
uses the native addEventHandler. As a result registering event listeners
is about 3 times faster.

In Node.JS console.log/error/warn functions actually resuls in a socket
write which in turn is considered by Zone.js as an async task.
This means that if there is any exception during change detection in a platform-server
application the error handler will make the Angular Zone unstable which
in turn will cause change detection to run on next tick and cause an
infinite loop.
It is also better to run the error handler outside of the Angular Zone
in general on all platforms so that an error in the error handler itself doesn't cause an
infinite loop.

Previously a projected view was only dirty checked when the
component in which it was inserted was dirty checked.

only the fact whether a projected view is dirty checked or not.

When a directive lives on the same element as a component
(e.g. `<my-comp myDir>`), the directive was not able to get hold
of the `ChangeDetectorRef` of the component on that element. However,
as directives are supposed to decorate components, this is incorrect.
This commit enables this use case.

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

first locate the corresponding element or text node.

Previously, a pipe that returned a `WrappedValue` would force the change

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
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.
Throwing on query changes would be a breaking change compared to v2.
Also discovers a bug with querying manually projected content, see #15117.

BREAKING CHANGES
`ComponentFactory.create()` takes an extra optional `NgModuleRef` parameter.
No change should be required in user code as the correct module will be used
when none is provided
DEPRECATIONS
The following methods were used internally and are no more required:
- `RouterOutlet.locationFactoryResolver`
- `RouterOutlet.locationInjector`
BREAKING CHANGE:
Perviously, any provider that had an ngOnDestroy lifecycle hook would be created eagerly.
Now, only classes that are annotated with @Component, @Directive, @Pipe, @NgModule are eager. Providers only become eager if they are either directly or transitively injected into one of the above.
This also makes all `useValue` providers eager, which
should have no observable impact other than code size.
EXPECTED IMPACT:
Making providers eager was an incorrect behavior and never documented.
Also, providers that are used by a directive / pipe / ngModule stay eager.
So the impact should be rather small.
Fixes#14552
The main use case for the generated source maps is to give
errors a meaningful context in terms of the original source
that the user wrote.
Related changes that are included in this commit:
* renamed virtual folders used for jit:
* ng://<module type>/module.ngfactory.js
* ng://<module type>/<comp type>.ngfactory.js
* ng://<module type>/<comp type>.html (for inline templates)
* error logging:
* all errors that happen in templates are logged
from the place of the nearest element.
* instead of logging error messages and stacks separately,
we log the actual error. This is needed so that browsers apply
source maps to the stack correctly.
* error type and error is logged as one log entry.
Note that long-stack-trace zone has a bug that
disables source maps for stack traces,
see https://github.com/angular/zone.js/issues/661.
BREAKING CHANGE:
- DebugNode.source no more returns the source location of a node.
