In certain circumstances (errors during component constructor) the router outlet may not be activated before
redirecting to a new route. If the new route requires running guards and resolvers the current logic will throw
when accessing outlet.component due to an isActivated check within the property getter. This update brings the
logic inline with deactivateRouterAndItsChildren, namely checking outlet.isActivated before trying to access
outlet.component.

To verify the correctness of the linker output, we leverage the existing
compliance tests. The plan is to test the linker by running all compliance
tests using a full round trip of pre-linking and subsequently post-linking,
where the generated code should be identical to a full AOT compile.
This commit adds an additional Bazel target that runs the compliance
tests in partial mode. Follow-up work is required to implement the logic
for running the linker round trip.

This is a precursor to introducing the Angular linker. As an initial

Currently it is impossible to determine the source of a binding that
generates `BoundAttribute` because all bound attributes generated from a
microsyntax expression share the same source span.
For example, in
```html
<div *ngFor="let item of items; trackBy: trackByFn"></div>
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
source span for all `BoundAttribute`s generated from microsyntax
```
the `BoundAttribute` for both `ngForOf` and `ngForTrackBy`
share the same source span.
A lot of hacks were necessary in View Engine language service to work
around this limitation. It was done by inspecting the whole source span
then figuring out the relative position of the cursor.
With this change, we introduce a flag to set the binding span as the
source span of the `ParsedProperty` in Ivy AST.
This flag is needed so that we don't have to change VE ASTs.
Note that in the binding parser, we already set `bindingSpan` as the
source span for a `ParsedVariable`, and `keySpan` as the source span for
a literal attribute. This change makes the Ivy AST more consistent by
propagating the binding span to `ParsedProperty` as well.

This commit adds an API to `NgCompiler`, a method called
`getComponentsWithTemplateFile`. Given a filesystem path to an external
template file, it retrieves a `Set` (actually a `ReadonlySet`) of component
declarations which are using this template. In most cases, this will only be
a single component.
This information is easily determined by the compiler during analysis, but
is hard for a lot of Angular tooling (e.g. the language service) to infer
independently. Therefore, it makes sense to expose this as a compiler API.

With the introduction of incremental type checking in #36211, an
intermediate `ts.Program` for type checking is only created if there are
any templates to check. This rendered some tests ineffective at avoiding
regressions, as the intermediate `ts.Program` was required for the tests
to fail if the scenario under test would not be accounted for. This
commit adds a single component to these tests, to ensure the
intermediate `ts.Program` is in fact created.
PR Close#39011
Prior to this fix, incremental rebuilds could fail to type check due to
missing ambient types from auto-discovered declaration files in @types
directories, or type roots in general. This was caused by the
intermediary `ts.Program` that is created for template type checking,
for which a `ts.CompilerHost` was used which did not implement the
optional `directoryExists` methods. As a result, auto-discovery of types
would not be working correctly, and this would retain into the
`ts.Program` that would be created for an incremental rebuild.
This commit fixes the issue by forcing the custom `ts.CompilerHost` used
for type checking to properly delegate into the original
`ts.CompilerHost`, even for optional methods. This is accomplished using
a base class `DelegatingCompilerHost` which is typed in such a way that
newly introduced `ts.CompilerHost` methods must be accounted for.

always belongs to current `TNode`. This simplifies the mental model

Even in the overloads, state that it can accept `null` and

Additionally, change the implementation to return `null` on an
`undefined` input, for consistency with other pipes.
BREAKING CHANGE:
The `slice` pipe now returns `null` for the `undefined` input value,

`undefined` being the result in that case, you now need to check for it
explicitly.

As shown in the tests, `KeyValuePipe.transform` can accept
`undefined`, in which case it always returns `null`.
Additionally, the typing for `string` keys can be made generic, so the
comparison function is only required to accept the relevant cases.
Finally, the typing for `number` records now shows that the comparison
function and the result entries will actually receive the string version
of the numeric keys, just as shown in the tests.
BREAKING CHANGE:
The typing of the `keyvalue` pipe has been fixed to report that for
input objects that have `number` keys, the result will contain the
string representation of the keys. This was already the case and the
code has simply been updated to reflect this. Please update the
consumers of the pipe output if they were relying on the incorrect
types. Note that this does not affect use cases where the input values
are `Map`s, so if you need to preserve `number`s, this is an effective
way.

The case conversion pipes no longer let falsy values through. They now
map both `null` and `undefined` to `null` and raise an exception on

For the following example, the cursor is between `keySpan` and `valueSpan`
of the `BoundAttribute`.
```html
<test-cmp [foo]¦="bar"></test-cmp>
```
Our hybrid visitor will return `Element`in this case, which is the parent
node of the `BoundAttribute`.
This is because we only look at the `keySpan` and `valueSpan`, and not
the source span. The last element in the AST path is `Element`, so it gets
returned.
In this PR, I propose fixing this by adding a sentinel value `undefined`
to the AST path to signal that we've found a source span but the cursor is
neither in the key span nor the value span.

Prior to this change, each invocation of `loadStandardTestFiles` would
load the necessary files from disk. This function is typically called
at the top-level of a test module in order to share the result across

where this call occurs, each loading their own copy of
`node_modules/typescript` which is ~60MB in size, so the memory overhead

In Ivy, template type-checking has 3 modes: basic, full, and strict. The
primary difference between basic and full modes is that basic mode only
checks the top-level template, whereas full mode descends into nested
templates (embedded views like ngIfs and ngFors). Ivy applies this approach
to all of its template type-checking, including the DOM schema checks which
validate whether an element is a valid component/directive or not.
View Engine has both the basic and the full mode, with the same distinction.
However in View Engine, DOM schema checks happen for the full template even
in the basic mode.
Ivy's behavior here is technically a "fix" as it does not make sense for
some checks to apply to the full template and others only to the top-level
view. However, since g3 relies exclusively on the basic mode of checking and
developers there are used to DOM checks applying throughout their template,
this commit re-enables the nested schema checks even in basic mode only in
g3. This is done by enabling the checks only when Closure Compiler
annotations are requested.
Outside of g3, it's recommended that applications use at least the full mode
of checking (controlled by the `fullTemplateTypeCheck` flag), and ideally
the strict mode (`strictTemplates`).
