This change is a prerequasity for a later change which will turn the
'di' into its own bazel package. In order to do that we have to:
- have `Injector` type be importable by Ivy. This means that we need
to create `Injector` as a pure type in `interface` folder which is
already a bazel package which Ivy can depend on.
- Remove the dependency of `class Injector` on Ivy so that it can be
compiled in isolation. We do that by using `-1` as special value for
`__NG_ELEMENT_ID__` which tells the Ivy `NodeInjector` than
`Injector` is being requested.

When an @NgModule decorator executes, the module is added to a queue in
render3/jit/module.ts. Reading an ngComponentDef property causes this queue
to be flushed, ensuring that the component gets the correct module scope
applied.
In before_each.ts, a global beforeEach is added to all Angular tests which
calls TestBed.resetTestingModule() prior to running each test. This in turn
clears the module compilation queue (which is correct behavior, as modules
declared within the test should not leak outside of it via the queue).
So far this is okay. But before the first test runs, the module compilation
queue is full of modules declared in global scope. No definitions have been
read, so no flushes of the queue have been triggered. The global beforeEach
triggers a reset of the queue, aborting all of the in-progress global
compilation, breaking those classes when they're later used in tests.
This commit adds logic to TestBedRender3 to respect the state of the module
queue before the TestBed is first initialized or reset. The queue is flushed
prior to such an operation to ensure global compilation is allowed to finish
properly.
With this fix, a platform-server test now passes (previously the <my-child>
element was not detected as a component, because the encompassing module
never finished compilation.

An @NgModule with invalid provider declarations produces errors under
normal circumstances. However, within the TestBed two small issues with
provider overrides interfered with the correct production of these errors:
1. a 'null' provider object caused a premature crash when the TestBed
attempted to check for a 'provide' property on it with hasOwnProperty().
2. the array of providers would have an empty override array appended to it
for each input provider, which would pollute the error messages produced
down the line.
This commit fixes both of these issues, by 1) checking for null and 2)
filtering out the empty override arrays.

An @NgModule with an 'id' property has its type registered in a global map
of modules by id. This happens during compilation of the module.
In Ivy, modules are first compiled when the @NgModule decorator executes.
In tests, they might be passed again through the TestBed's compiler,
resulting in a second compilation and registration.
Before this fix, this second registration would cause an error, as the id
was previously registered. This commit makes the registration idempotent,
so if the same module type is being registered for the same id then no
error is thrown.

Libraries that create components dynamically using component factories,
such as `@angular/upgrade` need to pass blocks of projected content
through to the `ComponentFactory.create()` method. These blocks
are extracted from the content by matching CSS selectors defined in
`<ng-content select="..">` tags found in the component's template.
The Angular compiler collects these CSS selectors when compiling a component's
template, and exposes them via the `ComponentFactory.ngContentSelectors`
property.
This change ensures that this property is filled correctly when the
component factory is created by compiling a component with the Ivy engine.

Currently the ImportManager class handles various rewriting actions of
imports when compiling @angular/core. This is required as code compiled
within @angular/core cannot import from '@angular/core'. To work around
this, imports are rewritten to get core symbols from a particular file,
r3_symbols.ts.
In this refactoring, this rewriting logic is moved out of the ImportManager
and put behind an interface, ImportRewriter. There are three implementers
of the interface:
* NoopImportRewriter, used for compiling all non-core packages.
* R3SymbolsImportRewriter, used when ngtsc compiles @angular/core.
* NgccFlatImportRewriter, used when ngcc compiles @angular/core (special
logic is needed because ngcc has to rewrite imports in flat bundles
differently than in non-flat bundles).
This is a precursor to using this rewriting logic in other contexts besides
the ImportManager.

These tests validate the ability of the View Engine TestBed to consume
summary metadata, a mechanism which allows the TestBed to use
AOT-compiled components & directives in tests. It achieves this through
two operations which are independently obsolete in Ivy:
1. It injects CompileMetadataResolver, a View Engine specific compiler
internal class which extracts global analysis metadata from classes,
and uses it to construct summary metadata. This happens in a
beforeEach() block which calls createSummaries().
2. It uses TestBed.initTestEnvironment to pass summary metadata to the
TestBed itself. Any such metadata is ignored in Ivy.
Operation #1 makes it impossible to run these tests under Ivy, as the
CompileMetadataResolver is not available with an Ivy compiler.
Ivy itself does not rely on summary data, and the R3TestBed can depend
directly on AOT compiled components without it. Thus, the spirit of thes
tests is obsolete in an Ivy world.

A constructor function may have been "synthesized" by TypeScript during
JavaScript emit, in the case no user-defined constructor exists and e.g.
property initializers are used. Those initializers need to be emitted
into a constructor in JavaScript, so the TypeScript compiler generates a
synthetic constructor.
This commit adds identification of such constructors as ngcc needs to be
able to tell if a class did originally have a constructor in the
TypeScript source. When a class has a superclass, a synthesized
constructor must not be considered as a user-defined constructor as that
prevents a base factory call from being created by ngtsc, resulting in a
factory function that does not inject the dependencies of the superclass.
Hence, we identify a default synthesized super call in the constructor
body, according to the structure that TypeScript emits.

Previously, ngtsc would assume that a given directive/pipe being imported
from an external package was importable using the same name by which it
was declared. This isn't always true; sometimes a package will export a

directive names with the 'ɵ' character to indicate that they're part of
the package's private API, and not for public consumption.
This commit introduces the TsReferenceResolver class which, given a
declaration to import and a module name to import it from, can determine
the exported name of the declared class within the module. This allows

Prior to this commit, we had two different modes for change detection
execution for Ivy, depending on whether you called `bootstrap()` or
`renderComponent()`. In the former case, we would complete creation
mode for all components in the tree before beginning update mode for
any component. In the latter case, we would run creation mode and
update mode together for each component individually.
Maintaining code to support these two different execution orders was
unnecessarily complex, so this commit aligns the two bootstrapping
mechanisms to execute in the same order. Now creation mode always
runs for all components before update mode begins.
This change also simplifies our rendering logic so that we use
`LView` flags as the source of truth for rendering mode instead of

simple custom `Error` that won't imply that there is more information
hidden.

Relative imports in Typescript files only work when module_name is
defined in ts_library (when run in Node.js).
See issue https://github.com/bazelbuild/rules_typescript/issues/360
With that fixed, `ng test` now works.
`ng build` requires `node_modules` to be available in the project
directory, so it's not usable yet. Running `yarn` in project directory
does not work because of postinstall version check.

In ngUpgrade (dynamic) we create a dynamic Angular `Directive` that wraps AngularJS components
that are being upgraded. The constructor of this `Directive` class returns a different instance
than `this`. It is this instance that actually contains the life-cycle hook handlers.
This would break in ivy, since the methods on the prototype of the original class are wired up,
rather than the instance methods. This results in hooks like `ngOnInit` not being called.
This commit refactors the code to extend the inner class that was being returned so that the
prototype chain is correct for both ViewEngine and ivy.
This change resolves a number of failing ivy tests, but also exposes other failures that were
masked by this issue. The tests have been updated accordingly.

`NgModule` requires that `Component`s/`Directive`s/`Pipe`s are listed in
declarations, and that each `Component`s/`Directive`s/`Pipe` is declared
in exactly one `NgModule`. This change adds runtime checks to ensure
that these sementics are true at runtime.
There will need to be seperate set of checks for the AoT path of the
codebase to verify that same set of semantics hold. Due to current
design there does not seem to be an easy way to share the two checks
because JIT deal with references where as AoT deals with AST nodes.

With the bundle info being assembled into a single object before the
transform is started, we now greedily create a TypeScript program up-front.
If a marker file exists that indicates that the bundle could be skipped
the program creation has already taken place which takes a significant
amount of time. This commit moves the marker check to occur before the
bundle is assembled.

ngcc would feed ngtsc with the function declaration inside of an IIFE as
that is considered the class symbol's declaration node, according to
TypeScript's `ts.Symbol.valueDeclaration`. ngtsc however only considered
variable decls and actual class decls as potential class declarations,
so given the function declaration node it would fail to generate the
`setClassMetadata` call.
ngtsc no longer makes its own assumptions about what classes look like,
but always asks the reflection host to yield this kind of information.

While creating FESM files, rollup usually drops all unused symbols.
All *__POST_R3__ are unused unless ngcc rewires stuff. To prevent this DCE
we reexport them as private symbols. If ngcc is not used, these symbols will
be dropped when we optimize an application bundle.

Prior to this change, we were unable to match directives using `ng-template` tags (for example the following selector would not work even though there might be some <ng-template>s in a template: `ng-template[directiveA]`. As a result, that broke some components that relies on such selectors to work. In order to resolve the problem, we now pass tag name to the `template` instruction (where we passed `null` before) and this tag name is used for matching at runtime. This update should also help support projecting containers, because the tag name is required to properly match such elements.

A surprising interaction with the MagicString library caused inserted
Ivy definitions to be dropped during the removal of decorators, iff all
decorators on the class could be removed. In that case, the removal
location corresponds with the exact location where Ivy definitions were
inserted into.
This commit moves the removal of decorators to occur before Ivy
definitions are inserted. This effectively avoids the problem, as later
inserted text fragments will be retained by MagicString.

All the tests in `packages/core/test/view/` are specific to the `ViewEngine` and shouldn't run for ivy. This PR introduces a new BUILD.bazel file to run those tests separately.
PR Close#27645
If a template contains specific TypeScript syntax, such as a non-null
assertion, the code that is emitted from ngcc into a JavaScript bundle
should not retain such syntax as it is invalid in JS.
A full-blown TypeScript emit of a complete ts.SourceFile would be
required to be able to emit JS and possibly downlevel into a lower
language target, which is not an option for ngcc as it currently
operates on partial ASTs, not full source files.
Instead, ngtsc no longer produces TypeScript specific syntax in the first
place, such that TypeScript print logic will only generate JS code.

In Ivy, a pure call to `setClassMetadata` is inserted to retain the
information that would otherwise be lost while eliding the Angular
decorators. In the past, the Angular constructor decorators were
wrapped inside of an anonymous function which was only evaluated once
`ReflectionCapabilities` was requested for such metadata. This approach
prevents forward references from inside the constructor parameter
decorators from being evaluated before they are available.
In the `setClassMetadata` call, the constructor parameters were not wrapped
within an anonymous function, such that forward references were evaluated
too early, causing runtime errors.
This commit changes the `setClassMetadata` call to pass the constructor
parameter decorators inside of an anonymous function again, such that
forward references are not resolved until requested by
`ReflectionCapabilities`, therefore avoiding the early reads of forward refs.

With ngcc's ability to fixup pre-Ivy ModuleWithProviders such that they
include a reference to the NgModule type, the type may become a qualified
name:
```
import {ModuleWithProviders} from '@angular/core';
import * as ngcc0 from './module';
export declare provide(): ModuleWithProviders<ngcc0.Module>;
```
ngtsc now takes this situation into account when reflecting a
ModuleWithProvider's type argument.

Currently the `ViewRef.destroy` method assumes that its index inside the view container will always be valid, however if it has been removed already, it'll be -1 which will throw an error.
The error manifested itself in one of the unit tests where a view had been detached during the test and then `TestBed` attempted to destroy its `ComponentRef` which ended threw an `Error during cleanup of component`.
