* Improves some of the generic assignability for tsurge. Anything is
allowed to be returned from an overridden `prepareProgram` method.
This is useful for the signal input migration.
* Passes the absolute root paths to migrations. This is helpful for the
signal input migration and there is no other way to access it. It's
better to pass specifically, compared to passing the whole unsafe
`ParsedConfiguration` object.

Introduces a migration framework to build batchable migrations that
can run in Large Scale mode against e.g. all of Google, using workers.
This is the original signal input migration infrastructure extracted
into a more generic framework that we can use for writing additional
ones for output, signal queries etc, while making sure those are not
scoped to a single `ts.Program` that limits them to per-directory
execution in very large projects (e.g. G3).
The migration will be updated to use this, and in 1P we will add
helpers to easily integrate such migrations into a Go-based pipeline
runner.

This commit updates the CHANGELOG to remove an entry about a breaking change in Zone.js, since the change was not actually released. It will be released separately in Zone.js package.

The migration was migrating all files in a project (like most migrations).
As there is no gain in migrating components used in test files. Excluding the test files reduces the migration noise.

This commit fully integrates the `autoDetect` feature into
`ApplicationRef.tick` without special handling for errors.
This commit also shares the method of autoDetect for change detection between
the zoneless and zone component fixture implementations. The difference
is now limited to:
* autoDetect is defaulted to true with zoneless
* detectChanges with zoneless is AppRef.tick while it is
ChangeDetectorRef.detectChanges with zones. This should likely
converge more in the future. Not going through AppRef.tick means that
the zone fixture does not get guaranteed `afterRender` executions and
does not get the rerunning behavior if the fixture is marked dirty by
a render hook.
BREAKING CHANGE: The `autoDetect` feature of `ComponentFixture` will now
attach the fixture to the `ApplicationRef`. As a result, errors during
automatic change detection of the fixture be reported to the `ErrorHandler`.
This change may cause custom error handlers to observe new failures that were previously unreported.
PR Close#55228
The zoneless scheduler callback was executed in the root zone rather
than simply in `runOutsideAngular` to allow us to land the hybrid mode
change detection (scheduler always enabled, even for zones) without
breaking a ton of existing `fakeAsync` tests that could/would fail with
the "timer(s) still in queue" error. However, this caused another
problem: when a test executes inside `fakeAsync`, it cannot flush the
scheduled time. A similar problem exists with event and run coalescing (#56767).
This change would allow `fakeAsync` to flush the zoneless-scheduled
change detections and minimize breaking existing tests
by flushing pending timers at the end of the test, which actually now
matches what's done internally.

Updates the migration so that it passes the type as a generic in the case of `@Inject(SOME_TOKEN) foo: SomeType`. This is done for two reasons:
1. It's a fairly common pattern and it ensures that the code can still be compiled.
2. It avoids leaving behind unused imports.

This commit fixes an issue when hydration serialization tries to calculate DOM path to a content projection node (`<ng-content>`), but such nodes do not have DOM representation.
Resolves#56750.
PR Close#57383
This commit updates the search results to query for the content as well
as a snippet of the content for display when it's the content that
matches the query rather than any of the headers.

Makes it so the inject migration preserves the optional token when declaring a parameter. This came up in some testing as something that can be potentially breaking for classes that implement interfaces.
PR Close#57367
This commit fixes an issue that happens when an i18n block is defined as a projectable content, but a parent component doesn't project it. With an extra check added in this commit, the code will be taking a regular "creation" pass instead of attempting hydration.
Resolves#57301.
PR Close#57356
Signal inputs are no longer updated by assignment, unlike `@Input()`, so
a good practice is adding `readonly` for the `InputSignal`— which should
never be swapped out.
This is a safe operation because the migration skips all inputs that are
being written anyway.
PR Close#57368
In some cases, the migration can detect when `input()` as a shorthand
may be usable. This commit adds such detection and migrates inputs to
this form when possible.
PR Close#57368
Components with `jit: true` are not processed by the Angular compiler,
so we cannot ask the template checker for the parsed template; simply
because the template wasn't attempted to be parsed.
We still can migrate simple cases of such components, commonly seen in
unit tests. We do this by manually parsing the template and making use
of the reference fallback resolution that is also used for host bindings
(where we don't have any type check block information).
PR Close#57347
Instead of exposing just the `ts.CompilerOptions`, we should expose the
actual Angular compiler options throuhgout the signal input migration.
This will be useful for parsing templates, in cases of JIT-opted
components.
PR Close#57347
As of this commit, the migration will also inspect safe property reads
and migrate them, if they reference an input that is being migrated.
PR Close#57318
Instead of revisiting each source file, and each of its child nodes
twice, we now visit them together using a grouped AST visitor that only
traverses each source file once.
This seemed to speed up migration by 6-8% locally, but is likely
noticable better with large compilation scopes.
PR Close#57318
Instead of fiddling manually with the imports, which worked well, but
comes at a cost of complexity— we are now using the canonical import
manager. This simplifies deletion, insertion and updating of imports.
Notably, our import manager is not super great at preserving whitespaces
right now, but we assume a formatter runs over migrated code anyway.
PR Close#57318
Introduces a best effort mode for the signal input migration. This mode
can be used to aggresively migrate as much as possible, ignoring most
of the incompatibility reasons, like "writes to the input".
PR Close#57318
Errors during change detection from `ApplicationRef.tick` are only
reported to the `ErrorHandler`. By default, this only logs the error to
console. As a result, these errors can be missed/ignored and allow tests
to pass when they should not. This change ensures that the errors are
surfaced. Note that this is already the behavior when zoneless is
enabled.
BREAKING CHANGE: Errors that are thrown during `ApplicationRef.tick`
will now be rethrown when using `TestBed`. These errors should be
resolved by ensuring the test environment is set up correctly to
complete change detection successfully. There are two alternatives to
catch the errors:
* Instead of waiting for automatic change detection to happen, trigger
it synchronously and expect the error. For example, a jasmine test
could write `expect(() => TestBed.inject(ApplicationRef).tick()).toThrow()`
* `TestBed` will reject any outstanding `ComponentFixture.whenStable` promises. A jasmine test,
for example, could write `expectAsync(fixture.whenStable()).toBeRejected()`.
As a last resort, you can configure errors to _not_ be rethrown by
setting `rethrowApplicationErrors` to `false` in `TestBed.configureTestingModule`.
