Previously in Ivy, host bindings did not work if they shared a public name
with an Input because they used the `elementProperty` instruction as is.
This instruction was originally built for inside component templates, so it
would either set a directive input OR a native property. This is the
correct behavior for inside a template, but for host bindings, we always
want the native properties to be set regardless of the presence of an Input.
This change adds an extra argument to `elementProperty` so we can tell it to
ignore directive inputs and only set native properties (if it is in the
context of a host binding).

In `ViewRef.detectChanges`, we are passing `ViewRef.context` into `detectChanges` to trigger change detection. This only makes sense for component `ViewRefs` (i.e. injected `ChangeDetectorRefs`) because with embedded views, `context` is not a component instance where the view has been monkey-patched. It's a just a normal object, so the view will be undefined.
In order to resolve this problem, we now invoke `detectChangesInternal` and also pass `LView` (to make sure we always have a view available).

We had two `NodeInjector` classes: one in `view_compatibility` and one in `di`. We replaced the one in `di` with the one from `view_compatibility` and reconciled their differences.

While generating attributes for `projection` instruction, we checked whether attribute name is equal to 'select' in lower case. However in other cases we treat 'select' attribute name as case-insensitive. This PR makes 'select' attribute consistently case-insensitive.

Prior to this change, animation properties were defined as element attributes, which caused errors at runtime. Now all animation-related attributes are defined as element properties.
Also as a part of this update, we start to account for bindings used in animations, which was previously missing.

When an Injector is provided, R3Injector instantiates it by calling its
constructor instead of its factory, not resolving dependencies.
With this fix, the ngInjectorDef is checked and the factory is correctly
used if it is found.

When detaching a view by its index via `ViewContainerRef.detach(index)`, in `ViewEngine` we used to return a new `ViewRef` ([for reference](https://github.com/angular/angular/blob/master/packages/core/src/view/refs.ts#L227)), however in Ivy we return the same `ViewRef` which means that its internal `_viewContainerRef` is never reset and we'll throw an error if the consumer tried to attach it to the `ApplicationRef`. These changes return a new `ViewRef` in order to match the original behavior.
These changes also add the same errors as `ViewEngine` when attempting to attach a view that is attached already. This was the original goal of this PR, however it ended up uncovering the issues with the `ViewRef`.

Prior to this change, the number of host vars stored for directives with `hostBindings` in expando block was incorrect for inherited directives (in case both parent and child directive have `hostBindings` defined). Now if we identify that we already added a `hostBinding` into expando block, we just increase the corresponding number of host binding vars

In Angular, it used to be an accepted practice to use strings as dependency
injection tokens. E.g. {provide: 'test', useValue: 'provided'}. However,
the Ivy node injection system did not support this. The Ivy DI system
attempts to patch a Bloom bit index onto each type registered with it, and
this patch operation does not work for a string token.
This commit adds string token support to the bloom filter system by
reserving bit 0 for string tokens. This eliminates the need for each string
token to store its own Bloom bit, at the expense of slightly more expensive
lookups of string tokens.

BREAKING CHANGE:
The public API for `DebugNode` was accidentally too broad. This change removes
1. Public constructor. Since `DebugNode` is a way for Angular to communicate information
on to the developer there is no reason why the developer should ever need to
Instantiate the `DebugNode`
2. We are also removing `removeChild`, `addChild`, `insertBefore`, and `insertChildAfter`.
All of these methods are used by Angular to constructor the correct `DebugNode` tree.
There is no reason why the developer should ever be constructing a `DebugNode` tree
And these methods should have never been made public.
3. All properties have been change to `readonly` since `DebugNode` is used by Angular
to communicate to developer and there is no reason why these APIs should be writable.
While technically breaking change we don’t expect anyone to be effected by this change.

A recent commit (probably 2c7386c) has changed the import graph of the
DI types in core, and somehow results in the ngc compiler deciding to
re-export core DI types from application factories which tangentially
use inject(). This is not really surprising; ngc's import graph can be
very unstable.
However, this results in a re-export of InjectFlags surviving JS
compilation. InjectFlags was a const enum, akin to an interface in TS,
with no runtime repesentation. This causes a warning to be emitted by
Webpack when it sees the re-export of InjectFlags.
This commit avoids the issue by removing 'const' from the declaration
of InjectFlags, causing it to have a runtime value. This is a temporary
fix. The real fix will be for ngc to no longer write exports of const
enums.
Testing strategy: manually verified. Due to the problem only manifesting
when recompiling after a change and then running Webpack, there is no
existing framework via which this could be easily tested with an
integration test. Additionally, the potential for this issue is gone in
Ivy, so this solution is only temporarily needed.
Fixes#27251.

Currently we store the `_appRef` when a `ViewRef` is attached, however we don't use it for anything. These changes use it to detach the view from the `ApplicationRef` when it is destroyed. These changes also fix that the `ComponentRef` doesn't remove its `ViewRef` on destroy.

When ngtsc compiles @angular/core, it rewrites core imports to the
r3_symbols.ts file that exposes all internal symbols under their
external name. When creating the FESM bundle, the r3_symbols.ts file
causes the external symbol names to be rewritten to their internal name.
Under ngcc compilations of FESM bundles, the indirection of
r3_symbols.ts is no longer in place such that the external names are
retained in the bundle. Previously, the external name `ɵdefineNgModule`
was explicitly declared internally to resolve this issue, but the
recently added `setClassMetadata` was not declared as such, causing
runtime errors.
Instead of relying on the r3_symbols.ts file to perform the rewrite of
the external modules to their internal variants, the translation is
moved into the `ImportManager` during the compilation itself. This
avoids the need for providing the external name manually.

When compiling the flat-file version of the `@angular/core` we need to be aware
that we cannot rely upon imported names to access the ivy definition functions.
The compiler is already clever enough to use local function calls rather than
trying to add a namespaced import, but there is a problem if the local name of the
function is different to the exported name. This is the case for functions that
are not part of the public API, and so are exported under a barred-O private alias.
In `@angular/core` the only decorations in use are `@NgModule` and `@Injectable`.
There are no directives, components, pipes, etc.
Since `defineInjectable` is part of the public API of `@angular/core`, the compiler
is able to generate code that references the original non-barred-O version of the
function.
But the `defineNgModule` is not part of the public API and so the compiler must
generate code that refers to it by the private barred-O version of the function.
This commit imports and then re-exports this barred-O version of `defineModule` to
ensure that the symbol is available in the local scope of the flat-file versions of
the `@angular/core` library.

This commit causes a call to setClassMetadata() to be emitted for every
type being compiled by ngtsc (every Angular type). With this metadata,
the TestBed should be able to recompile these classes when overriding
decorator information.
Testing strategy: Tests in the previous commit for
generateSetClassMetadataCall() verify that the metadata as generated is
correct. This commit enables the generation for each DecoratorHandler,
and a test is added to ngtsc_spec to verify all decorated types have
metadata generated for them.
PR Close#26860
This commit introduces the setClassMetadata() private function, which
adds metadata to a type in a way that can be accessed via Angular's
ReflectionCapabilities. Currently, it writes to static fields as if
the metadata being added was downleveled from decorators by tsickle.
The plan is for ngtsc to emit code which calls this function, passing
metadata on to the runtime for testing purposes. Calls to this function
would then be tree-shaken away for production bundles.
Testing strategy: proper operation of this function will be an integral
part of TestBed metadata overriding. Angular core tests will fail if this
is broken.
