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.

Updates the import manager to allow for a specific alias to be passed in. This is a prerequisite for switching schematics to the new import manager.
Note that passing in an alias disables identifier conflict resolution in order to avoid rewriting the alias that was passed in explicitly. For now this is fine since we have a very narrow use case for it, but we may want to revisit it in the future.

This commit adds golden tests for the signal input migration, along with
a tool to execute and automatically test the migration via the batch
mode, treating a single file as compilation unit.

This commit adds the batching logic helpers for running the signal
migration as a sharded/parallel action in Google3 and potentially
externally. The helpers are the main entry points for go/tsunami.

Adds the migration phase for migrating inputs and references. Thise
phase may execute as the third step when batching.
The migration is intentionally split into three phases:
1. Extract and analyze
2. Inheritance merge / merge of metadata
3. Migrate
This allows us to batch the migration in Google3, or for large projects,
merge metadata, and then batch-execute migration for computation of
replacements. This is compatible with Google's LSC tsunami tool.

E.g. detects `spyOn(myComp, 'input')`. This is problematic
as `input` no longer provides access to the raw value via property
access, but via a getter. The `spyOn` would be effictively a noop,
causing tests to fail. We skip such inputs for safety right now.
Similarly, we have an advisor for correcting type safety loss
with `.componentInstance` in unit tests. This is a common pattern
but is typed in Angular core as `any`. This breaks resolution of
references and we accidentally miss those. This advisor mitigates that.

This commit adds the logic for detecting and capturing references to
Angular `@Input`s. Those references may be migrated to unwrap signals
as part of the migration; or are refactored into temporary variables.
This commit detects and captures:
- host bindings references
- template references
- TypeScript references
PR Close#57082
This commit adds logic for AST traversing Angular HTML templates and
detecting references to Angular `@Input`s that may be migrated.
In addition, the expression visitor logic is built in a generic way so
that it can also be used for finding references in host binding
expressions— where no type check block information is available.

This commit includes the initial logic for converting `@Input()` to
`input`. The logic is not fully polished in terms of what use-cases
and patterns we want to generate, but it's working pretty stable
with testing in Angular Material and some g3 targets.
We may improve this and e.g. generate the `input()` shorthand in a
couple of cases.
The commit also includes some related helpers/parts that are needed
for the migration phases.
Notably the conversion phase is split up into preparation and migration.
That is necessary because as part of analysing we already try to
prepare to see if it's "possible". This is necessary for the global
metadata analysis, so that we can know that certain references are
incompatible across compilation units (e.g. when running as a batch).
PR Close#57082
This commit adds the initial set of helpers and registries for tracking
inputs discovered in the signal input migration.
A few short summary notes:
- Every input has an unique key. This key is used for global analysis
that may be performed when the migration is executed on a per
individual unit basis in Google3 via e.g. go/tsunami — The keys allow
us to build a combined global metadata for e.g. references or figuring
out which inputs are incompatible or not.
- A known input may be _any_ input in an compilation unit/ the program.
E.g. even inputs from `d.ts`. We keep track of these inputs so that we
can later figure out if a reference `ts.Identifier` points to any of
those. In addition it allows us to attach incompatibility metadata to
those. I.e. incompatible for migration because "something writes to
the input".
PR Close#57082
This commit introduces the initial flow analysis logic for the input
migration. The flow analysis will allow us to determine which references
inside a flow container participate potentially in narrowing.
We can then use this information and the proposed restructred accesses
to refactor the accesses to use temporary variables where needed. E.g.
```
if (this.input) {
this.input.charAt(0);
}
```
```
const input_1 = this.input();
if (input_1) {
input_1.charAt(0);
}
```
Notably we could easily, naively figure out similar references in a flow
container and always use temporary variables, but this approach allows
us to minimally introduce such variables and this commonly leaves code
very readable when no narrowing was involved (noticable in g3 tests)
E.g. simple cases like:
```
this.input.bla();
this.input.bla();
```
would otherwise result in refactored expressions, leveraging a temporary
variable.

This allows use of poisoned data for migrations. Right now, migrations
often enable this flag by creating some deeper structures of the
Angular compiler, but with this change it's easier to enable as a
private compiler option.
This is helpful for migrations, specifically the signal input migration
as it allows us to generate as much TCB code as possible, for reference
resolution.

This commit exposes metadata about inputs that are defined inside
the `inputs` field of `@Directive` or `@Component` class decorators

This option was introduced out of caution as a way for developers to opt out of the new behavior in v18 which schedule change detection for the above events when they occur outside the Zone. After monitoring the results post-release, we have determined that this feature is working as desired and do not believe it should ever be disabled by setting this option to `true`.

Adds the new `ng generate @angular/core:inject-migration` schematic that will convert existing code from constructor-based injection to injection using the `inject` function. The migration also has a few options that should help reduce compilation errors.
This migration is slightly different than our usual ones in that it may have to update entire class or constructor declarations. We don't go through the `ts.factory.update*` APIs for this, because it can cause the entire declaration to be re-formatted. Instead, this migration tries to insert strings in a way that won't affect the user's formatting.

Some Angular template instructions that follow each other may be chained
together in a single expressions statement, containing a deeply nested
AST of call expressions. The number of chained instructions wasn't previously
limited, so this could result in very deep ASTs that cause stack overflow
errors during TypeScript emit.
This commit introduces a limit to the number of chained instructions to
avoid these problems.

The `Timeout` object in Node.js has a `refresh` method, used to restart `setTimeout`/`setInterval` timers. Before this commit, `Timeout.refresh` was not handled, leading to memory leaks when using `fetch` in Node.js. This issue arose because `undici` (the Node.js fetch implementation) uses a refreshed `setTimeout` for cleanup operations.
For reference, see: https://github.com/nodejs/undici/blob/1dff4fd9b1b2cee97c5f8cf44041521a62d3f133/lib/util/timers.js#L45Fixes: #56586

Fixes that the runtime implementation of `ɵɵngDeclareDirective` was interpreting the `hostDirectives` mapping incorrectly. Instead of treating the inputs/outputs as `['binding', 'alias']` arrays, it was parsing them as `['binding: alias']`.

In addition to quick fixes, this commit adds the ability to write
code refactoring actions that can be applied by users.
For example, we may implement a migration as a code refactoring action.
Notably the quick fix support, existing already, is insufficient as it
only allows for edits to be applied based on diagnostics shwon in e.g.
VSCode.

In #56358 we removed most of the places that untag the references to typecheck files, because it was causing the compiler to throw error when it produces diagnostics. This appears to have caused a regression in TS 5.4 which now emits the synthetic references.
