Currently the context for inject() is only set when the token is seen
for the first time. This has two issues:
* It should always be set when injecting from that injector, because
a constructor may wish to call inject() directly.
* If an NgModuleFactory is .create()'d twice, and an ngInjectableDef
token is requested from each of them, the second time will fail.
This is because the first injection adds the provider definition
and calls the factory, and the provider definitions are shared.
The second injector will see the provider definition and call the
factory to create an instance, but without setting the correct
context for inject().
Fixes angular/material2#10586.

This lets projects like Material change ng_package "bundle index" files to non-conflicting paths
Currently packages like @angular/core ship with the generated metadata
in a path like 'core.js' which overwrites one of the inputs.
Angular material puts the generated file in a path like 'index.js'
Either way these files generated by ng_module rules have the potential
to collide with inputs given by the user, which results in an error.
Instead, give users the freedom to choose a different non-conflicting name.
Also this refactors the ng_package rule, removing the redundant
secondary_entry_points attribute.
Instead, we assume that any ng_module in the deps with a module_name
attribute is a secondary entry point.

This commit fixes a bug that would result in views insert / remove
even if a view needed only refresh operation.
The crux of the bug was that we were looking for a view to update
only in the LContainer.nextIndex position. This is incorrect as a
view with a given block id could be present later in the views
array (this happens if we about to remove a view in the middle of
the views array).

can remove views in the middle of the views collection. Previously we
would remove views at the end of the collection only.

InjectionToken can be created with an ngInjectableDef, and previously
this allowed the full expressiveness of @Injectable. However, this
requires a runtime reflection system in order to generate factories
from expressed provider declarations.
Instead, this change requires scoped InjectionTokens to provide the
factory directly (likely using inject() for the arguments), bypassing
the need for a reflection system.
Fixes#22205

@Injectable() supports a scope parameter which specifies the target module.
However, it's still difficult to specify that a particular service belongs
in the root injector. A developer attempting to ensure that must either
also provide a module intended for placement in the root injector or target
a module known to already be in the root injector (e.g. BrowserModule).
Both of these strategies are cumbersome and brittle.
Instead, this commit adds a token APP_ROOT_SCOPE which provides a
straightforward way of targeting the root injector directly, without
requiring special knowledge of modules within it.
PR Close#22185
This commit bundles 3 important changes, with the goal of enabling tree-shaking
of services which are never injected. Ordinarily, this tree-shaking is prevented
by the existence of a hard dependency on the service by the module in which it
is declared.
Firstly, @Injectable() is modified to accept a 'scope' parameter, which points
to an @NgModule(). This reverses the dependency edge, permitting the module to
not depend on the service which it "provides".
Secondly, the runtime is modified to understand the new relationship created
above. When a module receives a request to inject a token, and cannot find that
token in its list of providers, it will then look at the token for a special
ngInjectableDef field which indicates which module the token is scoped to. If
that module happens to be in the injector, it will behave as if the token
itself was in the injector to begin with.
Thirdly, the compiler is modified to read the @Injectable() metadata and to
generate the special ngInjectableDef field as part of TS compilation, using the
PartialModules system.
Additionally, this commit adds several unit and integration tests of various
flavors to test this change.
PR Close#22005
All of the providers in a module get compiled into a module definition in the
factory file. Some of these providers are for the actual module types, as those
are available for injection in Angular. For tree-shakeable tokens, the runtime
needs to be able to distinguish which modules are present in an injector.
This change adds a NodeFlag which tags those module providers for later
identification.

Implement NgOnChangesFeature, ViewContainerRef, TemplateRef,

PR Close#21430
To prepare for pending ngForOf work, the dep from instructions -> query
should be broken. This will enable a dep from di -> instructions while
avoiding a di -> instructions -> query -> di cycle.
Analyzing this cycle also uncovered another problem: the implementation
of query() breaks tree-shaking through a hard dependency on DI concepts
of TemplateRef, ElementRef, ViewContainerRef. This is fundamentally due
to how query() can query for those values without any configuration.
Instead, this fix introduces the concept by employing the strategy
pattern, and redefining QueryReadType to pass a function which will
return one of the above values. This strategy is then used for 'read'
instead of an enum in cases where special values should be read from
the DI system.

Structural directives can now specify a type guard that describes
what types can be inferred for an input expression inside the

NgIf was modified to declare an input guard on ngIf.
After this change, `fullTemplateTypeCheck` will infer that
usage of `ngIf` expression inside it's template is truthy.
For example, if a component has a property `person?: Person`
and a template of `<div *ngIf="person"> {{person.name}} </div>`
the compiler will no longer report that `person` might be null or
undefined.
The template compiler will generate code similar to,
```
if (NgIf.ngIfTypeGuard(instance.person)) {
instance.person.name
}
```
to validate the template's use of the interpolation expression.
Calling the type guard in this fashion allows TypeScript to infer
that `person` is non-null.

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).
This is needed as:
- closure declares globals itself for minified names, which sometimes clobber our `ng` global
- we can't declare a closure extern as the namespace `ng` is already used within Google for typings for angularJS (via `goog.provide('ng....')`).
The new expression lowering lowers everything after `useValue` / `useFactory`
into a separate exported variable. If the value was a `forwardRef`, this
was passed to the runtime and resulted in errors.
This change unwraps `forwardRef`s during runtime again.
Note: we can’t unwrap the `forwardRef` into an exported variable
during compile time, as this would defeat the purpose of the
`forwardRef` in referring to something that can’t be referred to
at this position.
