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.

This fixes an issue where a value would hide the type.
```
export interface Foo {
someMethod(): void;
}
export const Foo: Function = ...;
```
In the above example the `Foo` constant will hide the `interface Foo` symbol.
This change properly saves the interface in addition to the type.

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.

The way that `UpgradeAdapter` needs to be setup, you often find that
you must pass a `forwardRef` for an `NgModule.import`. Pre-ivy, this
gets resolved at runtime, but until this is implemented in ivy, we can
workaround it by resolving it in the `UpgradeAdapter` upfront.
This should be backward-compatible since by the time we actually
create the dynamic `NgModule` that has the import, the imported
class should be defined.
PR Close#27132
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.

In a more specific scenario: Considering people use a custom TypeScript compiler host with `NGC`, they _could_ expect only posix paths in methods like `writeFile`. This at first glance sounds like a trivial issue that should be just fixed by the actual compiler host, but usually TypeScript internal API's just pass around posix normalized paths, and therefore it would be good to follow the same standards when passing JSON genfiles to the `CompilerHost`.
For normal TypeScript files (and TS genfiles), this is already consistent because those will be handled by the actual TypeScript `Program` (see `emitCallback`).

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.

For each package entry-point there is only one format that
is used to compile the typings files (.d.ts). This will be

the appropriate format.

1) The `DecorationAnalyzer now analyzes all source files, rather than just
the entry-point files, which fixes#26183.
2) The `DecoratorAnalyzer` now runs all the `handler.analyze()` calls
across the whole entry-point *before* running `handler.compile()`. This
ensures that dependencies between the decorated classes *within* an
entry-point are known to the handlers when running the compile process.
3) The `Renderer` now does the transformation of the typings (.d.ts) files
which allows us to support packages that only have flat format
entry-points better, and is faster, since we won't parse `.d.ts` files twice.
PR Close#26403
The rendering of typings is not specific to the package
format, so it doesn't make sense to put it in a specific

The `NgModule` handler generates `R3References` for its declarations, imports,
exports, and bootstrap components, based on the relative import path
between the module and the classes it's referring to. This works fine for
compilation of a .ts Program inside ngtsc, but in ngcc the import needed
in the .d.ts file may be very different to the import needed between .js
files (for example, if the .js files are flattened and the .d.ts is not).
This commit introduces a new API in the `ReflectionHost` for extracting the
.d.ts version of a declaration, and makes use of it in the

This commit causes a call to setClassMetadata() to be emitted for every

This commit introduces generateSetClassMetadataCall(), an API in ngtsc
for generating calls to setClassMetadata() for a given declaration. The
reflection API is used to enumerate Angular decorators on the declaration,
which are converted to a format that ReflectionCapabilities can understand.
The reflection metadata is then patched onto the declared type via a call
to setClassMetadata().
This is simply a utility, a future commit invokes this utility for
each DecoratorHandler.
Testing strategy: tests are included which exercise generateSetClassMetadata
in isolation.
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.

Uglify and other tree-shakers attempt to determine if the invocation
of a function is side-effectful, and remove it if so (and the result
is unused). A /*@__PURE__*/ annotation on the call site can be used
to hint to the optimizer that the invocation has no side effects and
is safe to tree-shake away.
This commit adds a 'pure' flag to the output AST function call node,
which can be used to signal to downstream emitters that a pure
annotation should be added. It also modifies ngtsc's emitter to
emit an Uglify pure annotation when this flag is set.
Testing strategy: this will be tested via its consumers, by asserting
that pure functions are translated with the correct comment.

We are close enough to blacklist a few test targets, rather than whitelist targets to run...
Because bazel rules can be composed of other rules that don't inherit tags automatically,

- fixme-ivy-jit: target that doesn't yet build or run under ivy with --compile=jit
- fixme-ivy-local: target that doesn't yet build or run under ivy with --compile=local

This commit adds generation of .ngsummary.js shims alongside .ngfactory.js
shims when generated files are enabled.
Generated .ngsummary shims contain a single, null export for every exported
class with decorators that exists in the original source files. Ivy code
does not depend on summaries, so these exist only as a placeholder to allow
them to be imported and their values passed to old APIs. This preserves
backwards compatibility.
Testing strategy: this commit adds a compiler test to verify the correct
shape and contents of the generated .ngsummary.js files.

sufficient that the existing tests for factory shim generation continue

Originally, the ivy_switch mechanism used Bazel genrules to conditionally
compile one TS file or another depending on whether ngc or ngtsc was the
selected compiler. This was done because we wanted to avoid importing
certain modules (and thus pulling them into the build) if Ivy was on or
off. This mechanism had a major drawback: ivy_switch became a bottleneck
in the import graph, as it both imports from many places in the codebase
and is imported by many modules in the codebase. This frequently resulted
in cyclic imports which caused issues both with TS and Closure compilation.
It turns out ngcc needs both code paths in the bundle to perform the switch
during its operation anyway, so import switching was later abandoned. This
means that there's no real reason why the ivy_switch mechanism needed to
operate at the Bazel level, and for the ivy_switch file to be a bottleneck.
This commit removes the Bazel-level ivy_switch mechanism, and introduces
an additional TypeScript transform in ngtsc (and the pass-through tsc
compiler used for testing JIT) to perform the same operation that ngcc
does, and flip the switch during ngtsc compilation. This allows the
ivy_switch file to be removed, and the individual switches to be located
directly next to their consumers in the codebase, greatly mitigating the
circular import issues and making the mechanism much easier to use.
As part of this commit, the tag for marking switched variables was changed
from __PRE_NGCC__ to __PRE_R3__, since it's no longer just ngcc which
flips these tags. Most variables were renamed from R3_* to SWITCH_* as well,
since they're referenced mostly in render2 code.
Test strategy: existing test coverage is more than sufficient - if this
didn't work correctly it would break the hello world and todo apps.
