Although the prior commit has made more profiler events guaranteed symmetric
through the use of finally-blocks, there continue to be some situations
that could potentially result in asymmetric events, e.g. application
bootstrap doesn't guarantee symmetric events. This commit makes the profiler
lenient to these situations by unrolling the stack past the asymmetric event
data, eventually reaching the expected start event.
Profiler events are expected to be symmetric, yet in the case of errors this symmetry may break
if events aren't always kept in sync with their corresponding start event. This commit moves
various end events to be run from a finally-block, allowing them to notify the profiler even
when an error has occurred.
Fixes#62947
The `getControlDirective` is called multiple times, both at init and during each update run. Under the hood it performs a linear search for the `Field` directive.
We can speed this up by finding its index once and reusing it since the array of directive matches is static.

Refactor to use async/await for clearer asynchronous operations and enhanced error handling.
Simplify resource caching and streamline the resolution of component templates and styles.
Update in the router to align with the new async resource resolution.
The `fullInheritane` flag from the metadata and the `CopyDefinitionFeature` that it controls appear to no longer be used since `fullInheritance` is always false. The feature appears to have been there to support ngcc which was removed some time ago.
`new RegExp()` with computed strings can't be analyzed statically. The bundler can't prove the template string evaluation has no side effects; as thus this expression is considered a side-effect.
* Define `ResourceSnapshot<T>` as a type union of possible states for a
`Resource<T>`.
* Add `Resource.snapshot()` to convert a `Resource` to a signal of its
snapshot.
* Add `resourceFromSnapshots` to convert a reactive snapshot back into a
`Resource`.
By converting resources from/to `Signal<ResourceSnapshot>`s, full
composition of resources is now possible on top of signal composition APIs
like `computed` and `linkedSignal`.
For example, a common feature request is to have a `Resource` which retains
its value when its reactive source (params) changes. This can now be built
as a utility, leveraging `linkedSignal`'s previous value capability:
```ts
function withPreviousValue<T>(input: Resource<T>): Resource<T> {
const derived = linkedSignal({
source: input.snapshot,
computation: (snap, previous) => {
if (snap.status === 'loading' && previous?.value) {
// When the input resource enters loading state, we keep the value
// from its previous state, if any.
return {status: 'loading', value: previous.value.value};
}
// Otherwise we simply forward the state of the input resource.
return snap;
},
});
return resourceFromSnapshots(derived);
}
// In application code:
userId = input.required<number>();
user = withPreviousValue(httpResource(() => `/user/{this.userId()}`));
// if `userId()` switches, `user.value()` will keep the old value until
// the new one is ready!
```
We accounted for skipping leave animations during moves, but not swaps.
This accounts for the swap cases and updates how we deal with swaps and
moves. Now we always queue animations and then essentially dequeue them
if we attach them back in the same render pass.

this adds support for both leading and trailing segments before/after wildcard
route. Exposig the segments in a new _splat param would require a
breaking change to the return value of the matchers.

If a component template contains an icu expression it is being retained until the next change detection cycle for that template. This results in a net retention of only ever a single copy of the given lView but that creates an opportunity for compounding leaks.
Change the icu i18n_icu_container_visitor to free the IcuIteratorState retained lView when the stack is empty so that garbage collection can occur when the view is discarded.
When working with a proxy object such as signal forms' `Field`,
accessing the `lenght` or `Symbol.iterator` may trgger a reactive read.
This change ensures that `@for` properly captrues this before clearing
the active consumer.

We were clearing duplicate nodes when `animate.enter` fired fast, but not when solely `animate.leave` is fired and rapid toggles occur. This ensures that the `cancelLeavingNodes` function is called in all cases instead of just enter animations.

Previously, query parameters passed to `router.createUrlTree` were simply converted to strings. This meant that any custom serialization logic in a custom `UrlSerializer` was not applied. This could lead to inconsistencies between navigations triggered from the URL bar (which are parsed by the serializer) and navigations triggered programmatically.
This change ensures that query parameters are normalized using the provided `UrlSerializer`. The values are serialized and then parsed to ensure they are in the same format as if they had come from a URL. This allows custom serializers to handle complex objects in query parameters consistently.

Currently it's easy to make a mistake when accessing properties on `SimpleChanges`, because the keys aren't typed. These changes add an optional generic to the interface so that users can get a compilation error if they make a typo.
A few things to note:
1. The generic argument is optional and we revert to the old behavior if one isn't passed for backwards compatibility.
2. All of the keys are optional, because they aren't guaranteed to be present for any `ngOnChanges` invocation.
3. We unwrap the values of input signals to match the behavior at runtime.
Fixes#17560.

In some rare cases, it seems the animation queue disappears despite being afterEveryRender. This updates the animation scheduler to be afterNextRender instead and only schedules it when we need to.
