This change is a proof of concept of how the new Chrome DevTools
Performance extension API (https://bit.ly/rpp-e11y) can be used to
surface Angular runtime data directly in the Chrome DevTools Performance
panel.
Specifically, it implements the following changes:
1. Use the profiling status notification API to toggle the Timing API:
The notification API is implemented under the
chrome.devtools.performance extension namespace and consits of two
events: ProfilingStarted and ProfilingStopped, dispatched when the
Performance panel has started and stopped recording, respectively. This
API is used to enable the Timings API when the recording has started in
the Performance panel and disable it when recording has stopped.
2. Use the User Timings `detail` field format specification of the
Performance extension API
(https://developer.mozilla.org/en-US/docs/Web/API/Performance_API/User_timing)
to inject data collected by the Angular Profiler into the
Performance panel timeline. Angular Profiler uses several hooks to
measure framework tasks like change detection. With this change, this
measurements are visible in the same context as the runtime data
collected by the browser in the Performance Panel timeline.
Note: to enable the user timings to be collected in the first place, one
needs to open the Angular DevTools panel so that the related artifacts
are loaded in the page. This shortcoming can be fixed in a follow up so
that the extra step isn't necessary.

The behavior of `ComponentFixture` for zoneless tests was decided somewhat through guesswork, trial, and error. In addition, working on the zoneless fixture revealed oddities in the behavior of the zone-based fixture, or behaviors that we felt were counterintuitive. The most consequential difference is how change detection works: `detectChanges` goes through ApplicationRef.tick in zoneless while it is `changeDetectorRef.detectChanges` in the zone fixture.
We felt that running change detection through `ApplicationRef.tick` was important for several reasons:
* Aligning application behavior more closely with the test behavior (almost all views are attached to application ref in reality)
* Ensuring that afterRender* hooks are executed when calling `fixture.detectChanges`
* Ensuring that the change detection runs again if render hooks update state
This change, however, has some noticeable consequences that will break some tests, mostly around how errors are handled. `ApplicationRef.tick` catches errors that happen during change detection and reports them to the ErrorHandler from DI. The default error handler only logs the error to the console. This will break tests which have `expect(() => fixture.detectChanges()).toThrow()`. In addition, it allows tests to pass when there are real errors encountered during change detection.
This change ensures that errors from `ApplicationRef.tick` are rethrown
and will fail the test. We should also do a follow-up investigation to
determine whether we can/should also do this for the zone-based
`ComponentFixture`.

This reverts commit 66ffeca2de.
It looks like nuxt encountered the same issue with scrolling when
waiting for Vue's `nextTick`, which is a microtask. This would have
similar timing to ZoneJS's rendering in the microtask queue. This
reverts to a `setTimeout` alone, though recreates the problem in #53985.
This was also mentioned in one of the comments in the Nuxt issue and the
solution would be `rAF`.
In order to address #53985, we'd likely want to use the `race(rAF, setTimeout)`
that we use in the zoneless and coalescing schedulers. This would have effectively the same timing as
the `afterNextRender` implementation here with zoneless, but quite
different timing to `afterNextRender` with ZoneJS.

This commit updates the event binding part, where all `scroll` listeners are marked
as passive using the special zone.js configuration flag. The configuration has been

Adds an `ng update` migration to move users from using the phase flag

PR Close#55648
Adds back the ability to set the phase of an `afterRender` /
`afterNextRender` callback using the `phase` option. However, this API
is now deprecated, and the phase should instead be specified by passing
a spec object rather than a callback function.
PR Close#55648
Previously `afterRender` and `afterNextRender` allowed the user to pass
a phase to run the callback in as part of the `AfterRenderOptions`. This
worked, but made it cumbersome to coordinate work between phases.
```ts
let size: DOMRect|null = null;
afterRender(() => {
size = nativeEl.getBoundingClientRect();
}, {phase: AfterRenderPhase.EarlyRead});
afterRender(() => {
otherNativeEl.style.width = size!.width + 'px';
}, {phase: AfterRenderPhase.Write});
```
This PR replaces the old phases API with a new one that allows passing a
callback per phase in a single `afterRender` / `afterNextRender` call.
The return value of each phase's callback is passed to the subsequent
callbacks that were part of that `afterRender` call.
```ts
afterRender({
earlyRead: () => nativeEl.getBoundingClientRect(),
write: (rect) => {
otherNativeEl.style.width = rect.width + 'px';
}
});
```
This API also retains the ability to pass a single callback, which will
be run in the `mixedReadWrite` phase.
```ts
afterRender(() => {
// read some stuff ...
// write some stuff ...
});
```

Prior to this commit, a memory leak occurred when the `abort` listener was
not removed from the `AbortSignal`. We introduced a fix to remove the event
listener, but it was erroneously stored on the `taskData`, which is a shared
global object. Consequently, when something attempted to remove an event listener,
it immediately removed the last stored abort listener. As a result, events would
never be canceled.
We have now rectified this by storing the remove abort listener function directly on
the task itself. This adjustment ensures that the abort listener is tied only to the
specific task. When the `abort` function is called, it cancels the task. Therefore, it
is safe to associate the cleanup function directly with the task.

When a consumer switches its liveness state, it gets added to / removed from
the consumer list of all of its producers. This operation is transitive, so
if its producer is *also* a consumer and *its* liveness state is switched,
then the change is applied recursively.
Note that this only matters *if* the producer is also a consumer. However,
the logic in `producerAddLiveConsumer` / `producerRemoveLiveConsumerAtIndex`
coerced the producer node into a producer & consumer node, which allocated
extra arrays into the node structure that are never used. This didn't affect
correctness, but increased the memory usage of plain signal nodes (which are
just producers, never consumers).
This fix changes the logic in those operations to simply check if a producer
is also a consumer instead of coercing it into one.

Prior to this commit, event listener options were mutated directly, for example,
`options.signal = undefined` or `options.once = false`.
This issue arises in apps using third-party libraries where the responsibility lies
with the library provider. Some libraries, like WalletConnect, pass an abort controller
as `addEventListener` options. Because the abort controller has the `signal` property,
this is a valid case. Thus, mutating options would throw an error since `signal`
is a readonly property.
Even though zone.js is being deprecated as Angular moves towards zoneless change detection,
this fix is necessary for apps that still use zone.js and cannot migrate to zoneless change
detection because they rely on third-party libraries and are not responsible for the code
used in them.

Because exhaustive checks traverse the whole tree regardless of the
dirty state, it breaks some expectations around how change detection
should be running. When a view has transplanted views, it
unconditionally marks all ancestors for traversal, assuming this is fine
because the loop will just traverse them and find nothing dirty.
However, exhaustive checkNoChanages actually refreshes everything during
traversal.
This update ensures the exhaustive check only does a single pass and
also prevents some unnecessary marking of transplanted views for
refresh since we know they're going to be reached.

When an `@if` expression has an alias, only the type of the alias is
currently narrowed. So for example, suppose `value` is `string|undefined`:
```
@if (value; as alias) {
{{ value.length }} <!-- error, value may be undefined -->
{{ alias.length }} <!-- no error, alias is narrowed -->
}
```
This is especially noticeable when the expression contains guards which are
preconditions for the aliased expression:
```
@if (a && b; as alias) {...}
```
In this case, `a` would not be narrowed within the body, even though the
`@if` condition forces it to be truthy. This is a bug.
The reason is that aliased expressions were previously type-checked as:
```
var alias = a && b;
if (alias) {
// nothing other than alias is narrowed
...
}
```
One option considered was to emit `const alias` instead of `var alias`.
TypeScript _does_ trace `const` expressions and narrow their individual
components when the overall expression is guarded:
```
const alias = a && b;
if (alias) {
// a, b are also narrowed
}
```
However, this narrowing has different semantics than if `a && b` appeared
directly in the guard expression. For example, object properties aren't
narrowed with this approach, so component properties (which are referenced
as e.g. `this.a`) would not be narrowed.
Instead, we amend the guard expression to include both the expression _and_ the
alias variable, enforcing that both are narrowed.
```
var alias = a && b;
if ((a && b) && alias) {
// a, b, and alias all narrowed correctly.
}
```
This form ensures all conditions within the guard expression get narrowed
while also narrowing the alias variable type.

Currently when attempting to retrieve a TCB symbol for an input binding
that refers to a signal input with e.g. `protected`, while the
`honorAccessModifiersForInputBindings` flag is `false`, Angular will
throw a runtime exception because the symbol retrieval code always
expects a proper field access in the TCB.
This is not the case with `honorAccessModifiersForInputBindings =
false`, as TCB will allocate a temporary variable when ignoring the
field access. This will then trigger the runtime exception (which we
added to flag such "unexpected" cases). This commit handles it
gracefully, as it's valid TCB, but we simply cannot generate a proper
TCB symbol (yet). This is similar to `@Input` decorator inputs.
In the future we may implement logic to build up TCB symbols for
non-property access bindings, for both signal inputs or `@Input`
inputs. This commit just avoids a build exception.

Angular has long had the ability to use different interpolation delimiters
(by default `{{` and `}}`). This concept was copied over from AngularJS,
where AngularJS syntax is included in HTML sent over the network to the
browser. Occasionally developers would use SSR frameworks which _also_ have
interpolation syntaxes of their own, so there was a need to change the
delimiters used by AngularJS to avoid conflicts.
Since Angular templates are always processed by our compiler and the
interpolation characters are never processed by other systems first, this
option is vestigial in Angular and only increases the complexity of our
parser.

This makes Chrome recognize that local builds are the same extension leading to more intuitive behavior. It's also useful for allowlists of extension IDs to keep the local ID consistent.

Rather than attempting to use the native timing functions, this commit
simplifies the logic significantly by using the global timer functions
as they are, either patched or unpatched. When Zone is defined, we run
the timers in the root zone. This has more predictable behavior and
timing than (a) using both patched and unpatched versions of timers in
different places (b) trying to get an unpatched timer and failing due to
environment specifics and patches that aren't ZoneJS.

This reverts commit 7e89753eef.
Running render hooks inside the zone is specifically problematic for
`afterRender` hooks. If the callback has async task, it would cause an
infinite change detection. In addition, updating state in render hooks
is generally discourages and certainly should update state in a way that
notifies Angular of the change (either via signal or with `markForCheck`) rather
than relying on ZoneJS to pick it up (which would only work if the
change is done inside an async task).

This commit fixes an error in the looping logic of `ApplicationRef.tick`

Currently we add global extra imports to all the files in the compilation unit. However not all the files need extra imports. For example non-Angular files definitely do not need such extra imports, and in some cases these extra imports causes problems as the file is meant to be run the Node but it has Angular dependencies which are not compatible with Node. This change tries to limit extra import generation to a subset of files. Wit hthis change we create extra imports only for the files that contain at least one component whose NgModule is in a different file. This is because all other files do not need extra imports since they are either not Angular files or they already have all the imports that the components need.

These lines were not tree shakable by Closure Compiler because `.toString()` is special cased as a "pure" function eligible to eliminated if it's return value is unused. However `.toString.call` circumvents this and makes Closure Compiler think the function may have side effects. Switching to `.toString()` should be fine here as `process.toString()` in Node outputs `[object process]` so this should be safe. Presumably the original motivation for this roundabout approach was for type safety reasons which no longer apply as `_global` is `any`.

Fixes several issues with the `HttpClient` migration that showed up after I tried updating the Material docs site to the latest v18 release. Includes:
* The migration was assuming that all Angular decorators have at least one argument. This led to a null pointer error that broke the v18 update process when I was testing it.
* The migration incorrectly reimplemented the detection of classes with Angular decorators. This can cause code to be migrated incorrectly and doesn't handle cases like import aliases. I've switched it to use the existing tooling for detecting decorated classes.
* The migration was trying to migrate directives, even though they don't support the `imports` field.
* The migration was detecting `TestBed.configureTestingModule` calls using a raw string match which is very fragile and can be broken by the user's formatting.
* There were syntax errors in the unit tests.
* There were type checking errors in the unit tests, for example none of them were importing the Angular decorators that they were migrating.
There's more room for improvement, but this should resolve the most glaring issues without having to rewrite too much.

In Angular today, a bound listener automatically marks the view for
check. When using ZoneJS, these listeners are most often executed in the
Angular Zone as well, so synchronization (`ApplicationRef.tick`) will
eventually happen. _However_, developers can opt out of zone-patching
for events in several ways, and often do this for very frequent
listeners like `mousemove`, `resize`, and `scroll`. We do not want to
break existing expectations that these are now "safe" events to have
listeners for by automatically scheduling change detection regardless of
whether the listener executed inside or outside the Angular zone.
In contrast, in order for developers to more easily transition to zoneless,
we need to be able to ensure that components which are using `OnPush`
are, for the most part, compatible with zoneless as well. Because listeners
automatically mark the component for check, developers using `OnPush`
did not/do not need to also call `ChangeDetectorRef.markForCheck` or a
similar API. Unfortunately, this means that we need to consider the
listener callbacks as a notification to schedule a `tick` when Zoneless
is enabled. In the future, we would like to have an opt-out for this
(i.e. signal components) since it's not really how we _want_ things to work.

The timing of render hook execution is almost entirely identical to
`ngZone.onMicrotaskEmpty`. Developers working towards zoneless
compatibility will need to migrate `onMicrotaskEmpty` calls to use
`afterNextRender`/`afterRender` instead. This, however, would lead to
confusing issues if there are promises in the callbacks because
`onMicrotaskEmpty` emits inside the Angular zone while render hooks
execute outside today. This is problematic because it's not documented
and does not produce any notification or error message when async work
is done inside the hooks that requires change detection. Instead, change detection
simply does not run, and this behavior has proven to be surprising to
developers who are used to ZoneJS change detection behavior.

Mozilla requires add-ons to have reproducible builds and this is managed directly by human reviewers and need to understand how to build Angular DevTools correctly. This commit defines a reproducible way of building Angular DevTools which is useful for reviewers and contributers.
The actual changes I made include:
1. Moving local development content into `devtools/README` (deleting `devtools/DEVELOPING.md`) and explicitly stating the Node version as well as global Yarn install to be clear about the correct way to build the extension. This should make it easier for reviewers to understand and reproduce builds.
2. Moving release instructions to a separate doc to reduce noise as well as making some minor clean ups there.
I briefly considered pointing reviewers at a new `devtools/docs/reviewers.md` doc, but decided against it because I want these instructions to be maintained in a single location where contributors and reviewers use the same content. This way any changes don't miss one of these sets of users. If reviewers have trouble with this format (dev builds isn't useful to reviewers and some content is repeated from other docs for contributors) then we can consider splitting out to a separate `reviewers.md` file. But until then, I'd like to try sharing this content and see how it works out in practice.

`RouterOutlet` uses a unique injector logic that returns a value that correspond to the `ActivatedRoute` token dynamically. This logic breaks when a component/directive/pipe that injects the `ActivatedRoute` is located within a `@defer` block, because defer creates an `EnvironmentInjector` instance, which doesn't have that dynamic logic.
We've added some special handling of the `OutletInjector` in one of the previous commits, but it was incomplete and it was not covering cases when different routes use the same component. This commit updates defer logic to re-establish this dynamic behavior for `ActivatedRoute` by creating an instance of the `OutletInjector` when a parent injector was also an instance of `OutletInjector`.
This fix is a short-term solution and longer term we should find a way to achieve the dynamic behavior that Router relies on, but without adding a special case logic into defer.

When Angular receives a clear indication that change detection should
run again, this should not be ignored, regardless of what Zone it
happened in. This change updates the default change detection scheduling
approach of Zone-based applications to ensure a change detection will
run when these events happen outside the Angular zone (which includes,
for example, updating a signal that's read in a template, setting an
input of a `ComponentRef`, attaching a view marked for check, calling
`ChangeDetectorRef.markForCheck`, etc.).
This does not apply to applications using `NoopNgZone` or those which
have a custom `NgZone` implementation without ZoneJS.
The impact of this change will most often be seen in existing unit tests. Tests
execute outside the Angular Zone and this can mean that state in the
test is not fully recognized by Angular. Now that Angular will ensure
change detection _does_ run, even when the state update originates from
outside the zone, tests may observe additional rounds of change
detection compared to the previous behavior. Often, this should be seen
as more correct and the test should be updated, but in cases where it is
too much effort to debug, the test can revert to the old behavior by adding
`provideZoneChangeDetection({schedulingMode: NgZoneSchedulingMode.NgZoneOnly})`
to the `TestBed` providers.

In #54154 the quirk was fixed, but we kept support or some common expression because of internal usages. Now the internal usages have been cleaned up so the backwards-compatibility code can be deleted.
Externally a migration was added in #54630 that will automatically fix any places that depended on the old behavior.
BREAKING CHANGE:
Angular only supports writable expressions inside of two-way bindings.

When we started fixing the version mismatch with local 1st-party
packages, we also re-routed all dependencies like `@lezer/javascript`

There is quite some trickery going on with the adev build related to
local packages:
- Adev builds using npm packages from `/node_modules`
- At runtime, we are adding `HEAD` packages for e.g. `@angular/core` to
the bundles.
- At build time, the CLI, or Angular devkit may accidentally resolve to
`@angular/core` from `/node_modules/`— which is the core version from
npm, transitively installed via `@angular/docs`.
This causes a version mismatch, leading to issues like:
- CLI throwing because of a mismatch. https://github.com/angular/angular/issues/54858#issuecomment-2047188739
- Compiler changes not being picked up. https://github.com/angular/angular/issues/54858#issuecomment-2041322427
This commit attempts to fix this by:
- Linking all Angular `HEAD` packages into `adev/node_modules`. The
current logic attempts to link into `/node_modules`, but this does not
override existing `@angular/core`!
- Linking all direct external NPM packages, like
`@angular_devkit/build-angular` into `adev/node_modules` without their
transitive deps. This allows proper resolution of e.g. compiler as
node looks in `adev/node_modules` first, and falls back for the rest
to the execroot `node_modules`, or symlink target destination (if
`preserveSymlinks=false`).
Note: This is still not 100% ideal because a direct external NPM
dependency may have a transitive dependency that has another transitive
dependency on `@angular/core`. In those cases, the may be a conflict
that is not resolvable until we switch to a Bazel toolchain with better
first party resolution support.

`HttpClient` uses the `PendingTasks` service to contribute to
application stability. This was added in v16 to support SSR without
relying on an infinite `setTimeout` with ZoneJS like it did pre-v16.
Prior to version 16, this was also only done on the server and did not
affect clients or unit tests (https://github.com/angular/angular/commit/28c68f709cdc930e12bac51a266e7bf790656034).
Today, `PendingTasks` contribute to `ApplicationRef.isStable` but do not
contribute to the stability of `ComponentFixture`. This divergence in
stability behavior was not intended and we plan to make these two
stability indicators the same again, like they were when it was solely
based on the state of the Zone.
By aligning the two behaviors again, this would include all pending
tasks in the stability of fixtures. After investigation, this seems
likely to be a pretty large breaking change. Tests appear to quite often use
`await fixture.whenStable` when there are unfinished requests that have
not been mocked or flushed.
This change prevents request in `HttpClient` from contributing to
stability through the `PendingTasks` automatically but only when using
`HttpClientTesting`. In this scenario, requests need to be expected and
flushed manually for them to resolve. When the test backend and controllers
aren't used, requests should resolve on their own so `await fixture.whenStable`
shouldn't be particularly affected or problematic.

This change treats all views attached to `ApplicationRef` as `OnPush`,
meaning that they have to be explicitly marked for check in order to be
refreshed when a tick happens. This prevents "accidentally" refreshing
views which have `Default` change detection as a side effect of running
change detection from an unrelated notification.
In addition, this change helps us achieve one of the big goals of the
project: that we can provide a testing experience which gives developers
more confidence that a component is zoneless-compatible. Because
`ComponentFixture` change detection is run through `ApplicationRef`
instead of `ChangeDetectorRef` when zoneless is enabled, this ensures
that the component under test has correctly been marked for check in
order to be updated. Without this, calling
`ComponentFixture.detectChanges` would allow a test to _force_ change
detection on a view when Angular would have otherwise not known that it
needed to be updated. Calling `ComponentFixture.detectChanges` on a component
which is not marked for check will now omit refreshing component view.

of the fixture did not include everything that was considered in

incomplete requests. To fix this, remove the `whenStable`,
instead wait for another condition, or ensure `HttpTestingController`
mocks responses for all requests. Try adding `HttpTestingController.verify()`
before your `await fixture.whenStable` to identify the open requests.
Also, make sure your tests wait for the stability promise. We found many
examples of tests that did not, meaning the expectations did not execute
within the test body.

true in some scenarios but will now always be asynchronous.

This commit adds support for extracting initializer API functions.
Initialixer API functions are functions conceptually that can are
intended to be used as class member initializers.
Angular started introducing a few of these for the new signal
APIs, like `input`, `model` or signal-based queries.
These APIs are currently confusingly represented in the API docs because
the API extraction:
- does not properly account for call signatures of interfaces
- does not expose information about sub-property objects and call
signatures (e.g. `input.required`)
- the docs rendering syntax highlighting is too bloated and confusing
with all types being included.
This commit adds support for initializer API functions, namely two
variants:
- interface-based initializer APIs. e.g. `export const input:
InputFunction`- which is a pattern for `input` and `input.required`.
- function-based simpler initializer APIs with overloads. e.g.
`contentChildren` has many signatures but doesn't need to be an
interface as there are no sub-property call signatures.

* There's a new `ɵɵngDeclareClassMetadataAsync` function that is created for components that have deferred dependencies. It gets transpiled to `setClassMetadataAsync` and works in the same way by capturing a dependency loading function and setting the metadata after the dependencies are resolved.

Previously if and switch conditional would always use the first content as the
insertion container. This strategy interfered with content projection that
projects entire containers - as the consequence content for _all_ cases would
end up in slot matched by the first container. This could be very surprising
as desicribed in https://github.com/angular/angular/issues/54840
After the change each conditional content is projected into its own container.
This means that content projection can match more than one container and
result in correct display.

Previously we assumed that if a `for` loop tracking function is in the form of `someMethod($index, $item)`, it will be pure so we didn't pass the parameter to bind the context to it. This appears to be risky, because we don't know if the method is trying to access `this`.
These changes play it safe by always binding method-based tracking functions.

This commit refactors the router module to enhance performance by substituting the startsWith method with direct access `[0]` when verifying the value of a single character. This optimization improves efficiency, as direct access retrieves the character's value stored at a specific index in the string, resulting in slightly faster execution.

This change updates the approach to the loop in `ApplicationRef.tick`
for allowing state updates in `afterRender` hooks. It is valid to update
state in render hooks and we need to ensure we refresh views that may be
marked for check in these hooks (this can happen simply as a result of
focusing an element). This change ensures that the behavior of `markForCheck`
with respect to this loop does not change while we are actively running
change detection on a view tree.
This approach also has the benefit of preventing a regression for #18917,
where updating state in animation listeners can cause `ExpressionChanged...Error`
This should be allowed - there is nothing wrong with respect to unidirectional
data flow in this case.
There may be other cases in the future where it is valid to update
state. Rather than wrapping the render hooks and the animation flushing
in something which flips a global state flag, the idea here is that
`markForCheck` is safe and valid in all cases whenever change detection
is not actively running.

I initially tried switching to use public entry points under `zone.js/plugins/*`, however this file is both manually compiled for Saucelabs and also built with Bazel for a number of tests. The Bazel integration doesn't work well with depending on real NPM packages, so importing `zone.js/plugins/*` in that context doesn't really work. Instead we need to depend on the internals and manually call the `patch*` functions.

This was a bit complicated, but the typings test (`packages/zone.js/test/typings/...`) was failing due to an unresolved import on `./zone-impl`.
The main cause is that `//packages/zone.js:zone_js_d_ts` was generating the output `zone.d.ts` file by _concatenating_ `zone.d.ts` with `zone.api.extensions.d.ts` and `zone.configurations.api.d.ts`. Now that `zone.d.ts` imports `zone-impl.d.ts`, concatenation is no longer a viable means of bundling this content.
To fix this, I created a new `packages/zone.js/zone.ts` entry point and imported the underlying `zone.ts` file as well as the two extensions. I added `extract_types` to pull the `*.d.ts` files out of the target (because all the JS is bundled separately) and used those files in the final NPM package. This is sufficient to pass the typings test and should be equivalent to what exists today.

The `rxjs|electron` regex was causing `import { /* ... */ } from './electron';` to be treated as external and not bundled, which is an issue for the Electron entry point which just happens to be named `electron.ts`.

As this was, `__symbol__` was being called as a static field initializer, which runs during module evaluation, meaning it happened at import time. However for tests, the Zone prefix is overridden which changes the result of `__symbol__`. This change happens too late to be picked up by `__symbol__` at top-level execution, so instead we defer it until `symbolParentUnresolved` is actually read.

This moves timer patching from a top-level side effect into the `patchFakeAsyncTest` function. Top-level statements are evaluated before the Node patches run and have a chance to patch them with the Zone versions of these timers, meaning `FakeAsyncTestZoneSpec` was repatching the native versions between tests. The fix here is to grab the patched versions of these timers during the `patchFakeAsyncTest` function where we can be confident Node patches have already run.

While `TaskTrackingZoneSpec` was implicitly global previously, it does not need to be exposed in a `declare global {}` block.

Since each patch no longer contains top-level side effects, each bundled entry point needs to import and call its associated patch. For the most part this just means that each entry point imports the associated patch and invokes it at the top-level scope.
Note that many of these entry points did not actually have a dependency on `Zone` and had no guarantee that it was loaded prior to execution. To maintain consistency, the missing dependencies on `Zone` are left as-is. They will use the global instance of `Zone` and if users fail to load it prior to importing a specific patch, then the patch will fail just as it did previously.

This particular is slightly different from the others because it does not have a hard dependency on `Zone`. It doesn't actually use `Zone` directly during the patch because the patch just sets a `legacyPatch` global. To maintain consistency, this continues to use global `Zone` and does _not_ accept `Zone` as a parameter. While it's using a global in an inconvenient way, this isn't a problem right now because it doesn't cause or require a dependency on a top-level side effect.

This removes top-level side effects from each of these files and drops the dependency on global `Zone`, instead allowing it to be provided to each patch as a parameter.
Most of these are pure mechanical transformations. A couple notable files which were somewhat unique:
* `async-test.ts`, `fake-async-test.ts`, and `wtf.ts` had unique IIFE usage and patch `Zone` itself. This removes the IIFE and exports the function instead.
* `jest.ts` and `jasmine.ts` have a unique `jest` global usage which needs to be declared.

These are all the symbols originally under `declare global {}` with the same names. Unfortunatley TypeScript treats a `declare global {}` scope as the parent scope, so we need to import with a different name than the global, meaning everything gets an `_` prefix.

This removes a name collision on `Zone` with the interface. Otherwise putting the `interface Zone {}` and `class Zone {}` in the same scope when the IIFE is removed will cause a conflict.

This is just a straight copy, no code is altered. The new `zone-impl.ts` file will contain the actual definitions exported directly without any global declarations or top-level side effects. The existing `zone.ts` will remain as an entry point with those globals and side-effects.

This commit updates the logic for preserving file overview comments
to be more reliable and less dependent on previous transforms.
Previously, with the old import manager, we had a utility called
`addImport` that always separated import statements and non-import
statements. This meant that the non-emitted statement from Tsickle
for the synthetic file-overview comments no longer lived at the
beginning of the file.
`addImports` tried to overcome this by adding another new non-emitted
statement *before* all imports. This then was later used by the
transform (or was assumed!) to attach the synthetic file overview
comments if the original tsickle AST Node is no longer at the top.
This logic can be improved, because the import manager shouldn't need to
bother about this fileoverview non-emitted statement, and the logic for
re-attaching the fileoverview comment should be local. This commit fixes
this and makes it a local transform.

Enables the incremental type-checking test that we never enabled when we
landed signal inputs. Now that we fixed incremental re-use by re-using
the existing user imports for inline type check blocks, the test is
passing and can be enabled.
PR Close#54819
Updates the type-check block generation code (also for inline type check
blocks) to use the new import manager.
This is now a requirement because the translator utilities from the
reference emit environment expect an import manager that follows the
new contract established via `ImportGenerator<TFile, TExpression>`.
For type check files, we can simply print new imports as we don't expect
existing imports to be updated. That is because type check files do not
have any _original_ source files (or in practice— those are empty).
For type check blocks inline, or constructors, imports _may_ be re-used.
This is great as it helps fixing some incrementality bugs that we were
seeing in the type check code. That is, sometimes the type check block
code may generate imports conditionally for e.g. `TemplateRef`, or
animations. Those then **prevent** incremental re-use if TCB code
switches between those continously. We tried to account for that with
signal inputs by always pre-generating such imports. This fixed the
issue for type-check files, but for inline type check blocks this is
different as we would introduce new imports in user code that would then
be changed back in subsequential edit iterations. See:
https://github.com/angular/angular/pull/53521#pullrequestreview-1778130879.
In practice, the assumption was that we would be fine since user code is
most likely containing imports to `@angular/core` already. That is a
true assumption, but unfortunately it doesn't help with incremental
re-use because TypeScript's structural change detection does not dedupe
and expects 1:1 exact imports from their old source files.
https://github.com/microsoft/TypeScript/pull/56845
To improve incremental re-use for the type check integration, we should
re-use original source file imports when possible. This commit enables
this.

`ImportGenerator` is the abstraction used by the translator functions to
insert imports for `ExternalExpr` in an AST-agnostic way.
This was built specifically for the linker which does not use any of the

`ngImport.Bla`.
This commit also switches the linker AST-agnostic generator to follow

This commit introduces a new implementation of `ImportManager` that has
numerous benefits:
- It allows efficient re-use of original source file imports.
* either fully re-using original imports if matching
* updating existing import declarations to include new symbols.
- It allows efficient re-use of previous generated imports.
- The manager can be used for schematics and migrations.

built for schematics in Angular Material, but this commit improved it
to be more flexible, more readable, and "correct".

This commit ensures components in the route config predictably always
get their providers from the hierarchy available to routes rather than
sometimes being dependent on where they are inserted.
fixes#53369
BREAKING CHANGE: Providers available to the routed components always
come from the injector heirarchy of the routes and never inherit from
the `RouterOutlet`. This means that providers available only to the
component that defines the `RouterOutlet` will no longer be available to
route components in any circumstances. This was already the case
whenever routes defined providers, either through lazy loading an
`NgModule` or through explicit `providers` on the route config.

This commit updates the logic around `Route.redirectTo` to enable using a
function to create the redirect. This function can return a string,
ands acts the same as previous string redirects, or a `UrlTree`, which
will act as an absolute redirect.
To be useful, the redirect function needs access to the params and data.
Today, developers can access these in their redirect strings, for
example `{path: ':id', redirectTo: '/user/:id'}`. Unfortunately,
developers only have access to params and data on the _current route_
today in the redirect strings. The params and data in the `RedirectFn`
give developers access to anything from the matched parent routes as
well. This is done as the same way as param and data aggregation later
on (https://github.com/angular/angular/blob/897f014785578d87bc655ea6ae9e113653960f50/packages/router/src/router_state.ts#L236-L278).
In order to accomplish this, we inherit params and data while
matching, after the `ActivatedRouteSnapshot` is created for the matched
route rather than waiting until the end.
The `RedirectFunction` does not return the full
`ActivatedRouteSnapshot` interface. Some things are not accurately known
at the route matching phase. For example, resolvers are not run until
later, so any resolved title would not be populated. The same goes for lazy
loaded components. The is also true for all the snapshots up to the
root, so properties that include parents (root, parent, pathFromRoot)
are also excluded. And naturally, the full route matching hasn't yet
happened so firstChild and children are not available either.

only be a string on `Route` objects will need to be adjusted.

needs to execute after change detection, we recommend `afterNextRender`
instead of something like `setTimeout`.

The logic in `isCssClassMatching` is only interested in two areas in the attributes:
implicit attributes and the `AttributeMarker.Classes` area, with the first area only
of interest for projection matching, not directive matching. This commit splits these
two searches to make this more apparent.
PR Close#54800
This commit resolves a regression that was introduced when the compiler switched from
`TemplateDefinitionBuilder` (TDB) to the template pipeline (TP) compiler. The TP compiler
has changed the output of
```html
if (false) { <div class="test"></div> }
```
from
```ts
defineComponent({
consts: [['class', 'test'], [AttributeMarker.Classes, 'test']],
template: function(rf) {
if (rf & 1) {
ɵɵtemplate(0, App_Conditional_0_Template, 2, 0, "div", 0)
}
}
});
```
to
```ts
defineComponent({
consts: [[AttributeMarker.Classes, 'test']],
template: function(rf) {
if (rf & 1) {
ɵɵtemplate(0, App_Conditional_0_Template, 2, 0, "div", 0)
}
}
});
```
The last argument to the `ɵɵtemplate` instruction (0 in both compilation outputs) corresponds with
the index in `consts` of the element's attribute's, and we observe how TP has allocated only a single
attribute array for the `div`, where there used to be two `consts` entries with TDB. Consequently,
the `ɵɵtemplate` instruction is now effectively referencing a different attributes array, where the
distinction between the `"class"` attribute vs. the `AttributeMarker.Classes` distinction affects
the behavior: TP's emit causes the runtime to incorrectly match a directive with `selector: '.foo'` to
be instantiated on the `ɵɵtemplate` instruction as if it corresponds with a structural directive!
Instead of changing TP to align with TDB's emit, this commit updates the runtime instead. This uncovered
an inconsistency in selector matching for class names, where there used to be two paths dealing with
class matching:
1. The first check was commented to be a special-case for class matching, implemented in `isCssClassMatching`.
2. The second path was part of the main selector matching algorithm, where `findAttrIndexInNode` was being used
to find the start position in `tNode.attrs` to match the selector's value against.
The second path only considers `AttributeMarker.Classes` values if matching for content projection, OR of the
`TNode` is not an inline template. The special-case in path 1 however does not make that distinction, so it
would consider the `AttributeMarker.Classes` binding as a selector match, incorrectly causing a directive to
match on the `ɵɵtemplate` itself.
The second path was also buggy for class bindings, as the return value of `classIndexOf` was incorrectly
negated: it considered a matching class attribute as non-matching and vice-versa. This bug was not observable
because of another issue, where the class-handling in part 2 was never relevant because of the special-case
in part 1.
This commit separates path 1 entirely from path 2 and removes the buggy class-matching logic in part 2, as
that is entirely handled by path 1 anyway. `isCssClassMatching` is updated to exclude class bindings from
being matched for inline templates.

[Blog post "Angular v18 is now available"](http://goo.gle/angular-v18).
## Breaking Changes
### animations
- Deprecated `matchesElement` method has been removed from `AnimationDriver` as it is unused.
### common
- The deprecated `isPlatformWorkerUi` and `isPlatformWorkerApp` have been removed without replacement, as they serve no purpose since the removal of the WebWorker platform.
### compiler
- Angular only supports writable expressions inside of two-way bindings.
### compiler-cli
- * Angular no longer supports TypeScript versions older than 5.4.
### core
- `OnPush` views at the root of the application need to
be marked dirty for their host bindings to refresh. Previously, the host
bindings were refreshed for all root views without respecting the
`OnPush` change detection strategy.
- `OnPush` views at the root of the application need to
be marked dirty for their host bindings to refresh. Previously, the host
bindings were refreshed for all root views without respecting the
`OnPush` change detection strategy.
- The `ComponentFixture``autoDetect` feature will no
longer refresh the component's host view when the component is `OnPush`
and not marked dirty. This exposes existing issues in components which
claim to be `OnPush` but do not correctly call `markForCheck` when they
need to be refreshed. If this change causes test failures, the easiest
fix is to change the component to `ChangeDetectionStrategy.Default`.
- `ComponentFixture.whenStable` now matches the
`ApplicationRef.isStable` observable. Prior to this change, stability
of the fixture did not include everything that was considered in
`ApplicationRef`. `whenStable` of the fixture will now include unfinished
router navigations and unfinished `HttpClient` requests. This will cause
tests that `await` the `whenStable` promise to time out when there are
incomplete requests. To fix this, remove the `whenStable`,
instead wait for another condition, or ensure `HttpTestingController`
mocks responses for all requests. Try adding `HttpTestingController.verify()`
before your `await fixture.whenStable` to identify the open requests.
Also, make sure your tests wait for the stability promise. We found many
examples of tests that did not, meaning the expectations did not execute
within the test body.
In addition, `ComponentFixture.isStable` would synchronously switch to
true in some scenarios but will now always be asynchronous.
- Angular will ensure change detection runs, even when the state update originates from
outside the zone, tests may observe additional rounds of change
detection compared to the previous behavior.
This change will be more likely to impact existing unit tests.
This should usually be seen as more correct and the test should be updated,
but in cases where it is too much effort to debug, the test can revert to the old behavior by adding
`decreasePendingRequestCount` and `getPendingRequestCount` have been
removed. This information is tracked with zones.
### http
- By default we now prevent caching of HTTP requests that require authorization . To opt-out from this behaviour use the `includeRequestsWithAuthHeaders` option in `withHttpTransferCache`.
Example:
```ts
withHttpTransferCache({
includeRequestsWithAuthHeaders: true,
})
```
### platform-browser
- Deprecated `StateKey`, `TransferState` and `makeStateKey` have been removed from `@angular/platform-browser`, use the same APIs from `@angular/core`.
### platform-browser-dynamic
- No longer used `RESOURCE_CACHE_PROVIDER` APIs have been removed.
### platform-server
- deprecated `platformDynamicServer` has been removed. Add an `import @angular/compiler` and replace the usage with `platformServer`
- deprecated `ServerTransferStateModule` has been removed. `TransferState` can be use without providing this module.
- deprecated `useAbsoluteUrl` and `baseUrl` been removed from `PlatformConfig`. Provide and absolute `url` instead.
- Legacy handling or Node.js URL parsing has been removed from `ServerPlatformLocation`.
The main differences are;
- `pathname` is always suffixed with a `/`.
- `port` is empty when `http:` protocol and port in url is `80`
- `port` is empty when `https:` protocol and port in url is `443`
### router
- Guards can now return `RedirectCommand` for redirects
in addition to `UrlTree`. Code which expects only `boolean` or `UrlTree`
values in `Route` types will need to be adjusted.
- This change allows `Route.redirectTo` to be a function
in addition to the previous string. Code which expects `redirectTo` to
only be a string on `Route` objects will need to be adjusted.
- When a a guard returns a `UrlTree` as a redirect, the
redirecting navigation will now use `replaceUrl` if the initial
navigation was also using the `replaceUrl` option. If this is not
desirable, the redirect can configure new `NavigationBehaviorOptions` by
returning a `RedirectCommand` with the desired options instead of `UrlTree`.
- Providers available to the routed components always
come from the injector heirarchy of the routes and never inherit from
the `RouterOutlet`. This means that providers available only to the
component that defines the `RouterOutlet` will no longer be available to
route components in any circumstances. This was already the case
whenever routes defined providers, either through lazy loading an
`NgModule` or through explicit `providers` on the route config.

## FAQs
### The build is failing and I'm seeing `bazel:bazel failed: missing input file` messages.
This is most likely due to a bazel dependency / caching issue. To resolve this, run the following command:
```
# Try this first
yarn bazel clean
# If that doesn't work, try it with the expunge flag
