With the next version of the CLI we don't need to add logging for the description of the schematic as part of the schematic itself.
This is because now, the CLI will print the description defined in the `migrations.json` file.

Each of the XML based `TranslationParsers` was providing its own
`MessageSerializer`, but they are all very similar. So these have been
consolidated into a single more generic `MessageSerializer.
As a result of this, the extra layers of folders in the project seemed
unnecessary, so they have been flattened.

`bindingIndex` stores the current location of the bindings in the
template function. Because it used to be stored in `LView` that `LView`
was not reentrant. This could happen if a binding was a getter and had
a side-effect of calling `detectChanges()`.
By moving the `bindingIndex` to `LFrame` where all of the global state
is kept in reentrant way we correct the issue.

This commit simplifies the logic of `ExpressionVisitor` in
`completions.ts`.
Specifically,
1. helper functions `uniqueByName` and `lowerName` are removed.
2. Clean up the logic in visitElement()
3. Reorder constructor params
4. Add methods `addAttributeValuesToCompletions`,
`addKeysToCompletions`, and `addSymbolsToCompletions`.

This release brings in some important fixes. In particular the 2 segment linker fix for the new rollup_bundle and the strict peerDeps requirement will be important for angular users that opt in to bazel. See https://github.com/bazelbuild/rules_nodejs/releases/tag/0.39.0 for more details.

The `localize-translate` command line tool can now accept an array of
target locales to support the case where translation files do not
contain them. Specify this array via the `--target-locales` option.
NOTE to early adopters: in order to support this, the original `-t`
option for the binary has changed from being a glob pattern to an array
of paths, which will have matching indices to any provided target-locales.
PR Close#33381
Previously the target locale of a translation file had to be extracted
from the contents of the translation file. Therefore it was an error if
the translation file did not provide a target locale.
Now an array of locales can be provided via the `translationFileLocales`
option that overrides any target locale extracted from the file.
This allows us to support translation files that do not have a target
locale specified in their contents.

Currently the `missing-injectable` migration seems to add
`@Injectable()` to third-party classes in type definitions.
This not an issue in general since we do not generate broken code
by inserting a decorator into a type definition file. Though, we can
avoid adding the decorator since it won't have any effect and in
general we should not write to non source files of the compilation unit.

We should not migrate the reference from `useExisting`. This is because
developers can only use the `useExisting` value as a token. e.g.
```ts
@NgModule({
providers: [
{provide: AppRippleConfig, useValue: rippleOptions},
{provide: MAT_RIPPLE_OPTIONS, useExisting: AppRippleConfig},
]
})
export class AppModule {}
```
In the case above, nothing should be decorated with `@Injectable`. The
`AppRippleConfig` class is just used as a token for injection.

Currently the migration is unable to migrate instances where
the provider definition uses `forwardRef`. Since this is a
common pattern, we should support that from within the migration.
The solution to the problem is adding a foreign function resolver
to the `PartialEvaluator`. This basically matches the usage of
the static evaluation that is used by the ngtsc annotations.

PS: I considered moving the ng_rollup bundle into the macro but I didn't want to make
too many changes in this PR. If we find running benchmarks in this way useful, we
should refactor the build file more, and move the ng_rollup_bundle targets into the

Removes `ngBaseDef` from the compiler and any runtime code that was still referring to it. In the cases where we'd previously generate a base def we now generate a definition for an abstract directive.
PR Close#33264
For abstract directives, i.e. directives without a selector, it may
happen that their constructor is called explicitly from a subclass,
hence its parameters are not required to be valid for Angular's DI
purposes. Prior to this commit however, having an abstract directive
with a constructor that has parameters that are not eligible for
Angular's DI would produce a compilation error.
A similar scenario may occur for `@Injectable`s, where an explicit
`use*` definition allows for the constructor to be irrelevant. For
example, the situation where `useFactory` is specified allows for the
constructor to be called explicitly with any value, so its constructor
parameters are not required to be valid. For `@Injectable`s this is
handled by generating a DI factory function that throws.
This commit implements the same solution for abstract directives, such
that a compilation error is avoided while still producing an error at
runtime if the type is instantiated implicitly by Angular's DI
mechanism.

Also removes `build:remote --spawn_strategy=remote` from .bazelrc. It seems that with Bazel 1.0.0 setting `--incompatible_list_based_execution_strategy_selection=false` no longer works around the issue with npm_package that it did when it was added. The error that was originally observed has returned after updating to Bazel 1.0.0:
```
ERROR: /home/circleci/ng/packages/angular_devkit/build_optimizer/BUILD:66:1: Assembling npm package packages/angular_devkit/build_optimizer/npm_package failed: No usable spawn strategy found for spawn with mnemonic Action.

```
This commit removes both `—incompatible_list_based_execution_strategy_selection=false` as well as `build:remote --spawn_strategy=remote` which means that Bazel will do the default behavior of picking the first available strategy from the default list, which is `remote,worker,sandboxed,local`.

In Angular View Engine, there are two kinds of decorator inheritance:
1) both the parent and child classes have decorators
This case is supported by InheritDefinitionFeature, which merges some fields
of the definitions (such as the inputs or queries).
2) only the parent class has a decorator
If the child class is missing a decorator, the compiler effectively behaves
as if the parent class' decorator is applied to the child class as well.
This is the "undecorated child" scenario, and this commit adds a migration
to ngcc to support this pattern in Ivy.
This migration has 2 phases. First, the NgModules of the application are
scanned for classes in 'declarations' which are missing decorators, but
whose base classes do have decorators. These classes are the undecorated
children. This scan is performed recursively, so even if a declared class
has a base class that itself inherits a decorator, this case is handled.
Next, a synthetic decorator (either @Component or @Directive) is created
on the child class. This decorator copies some critical information such
as 'selector' and 'exportAs', as well as supports any decorated fields
(@Input, etc). A flag is passed to the decorator compiler which causes a
special feature `CopyDefinitionFeature` to be included on the compiled
definition. This feature copies at runtime the remaining aspects of the
parent definition which `InheritDefinitionFeature` does not handle,
completing the "full" inheritance of the child class' decorator from its
parent class.
PR Close#33362
This commit adds CopyDefinitionFeature, which supports the case where an
entire decorator (@Component or @Directive) is inherited from parent to
child.
The existing inheritance feature, InheritDefinitionFeature, supports merging
of parent and child definitions when both were originally present. This
merges things like inputs, outputs, host bindings, etc.
CopyDefinitionFeature, on the other hand, compensates for a definition that
was missing entirely on the child class, by copying fields that aren't
ordinarily inherited (like the template function itself).
This feature is intended to only be used as part of ngcc code generation.

When upgrading an Angular application to a new version using the Angular
CLI, built-in schematics are being run to update user code from
deprecated patterns to the new way of working. For libraries that have
been built for older versions of Angular however, such schematics have
not been executed which means that deprecated code patterns may still be
present, potentially resulting in incorrect behavior.
Some of the logic of schematics has been ported over to ngcc migrations,
which are automatically run on libraries. These migrations achieve the
same goal of the regular schematics, but operating on published library
sources instead of used code.
PR Close#33362
Previously, the (currently disabled) undecorated parent migration in
ngcc would produce errors when a base class could not be determined
statically or when a class extends from a class in another package. This
is not ideal, as it would cause the library to fail compilation without
a workaround, whereas those problems are not guaranteed to cause issues.
Additionally, inheritance chains were not handled. This commit reworks
the migration to address these limitations.
PR Close#33362
In ngcc's migration system, synthetic decorators can be injected into a
compilation to ensure that certain classes are compiled with Angular
logic, where the original library code did not include the necessary
decorators. Prior to this change, synthesized decorators would have a
fake AST structure as associated node and a made-up identifier. In
theory, this may introduce issues downstream:
1) a decorator's node is used for diagnostics, so it must have position
information. Having fake AST nodes without a position is therefore a
problem. Note that this is currently not a problem in practice, as
injected synthesized decorators would not produce any diagnostics.
2) the decorator's identifier should refer to an imported symbol.
Therefore, it is required that the symbol is actually imported.
Moreover, bundle formats such as UMD and CommonJS use namespaces for
imports, so a bare `ts.Identifier` would not be suitable to use as
identifier. This was also not a problem in practice, as the identifier
is only used in the `setClassMetadata` generated code, which is omitted
for synthetically injected decorators.
To remedy these potential issues, this commit makes a decorator's
identifier optional and switches its node over from a fake AST structure
to the class' name.

A class that is provided as Angular service is required to have an
`@Injectable()` decorator so that the compiler generates its injectable
definition for the runtime. Applications are automatically migrated
using the "missing-injectable" schematic, however libraries built for
older version of Angular may not yet satisfy this requirement.
This commit ports the "missing-injectable" schematic to a migration that
is ran when ngcc is processing a library. This ensures that any service
that is provided from an NgModule or Directive/Component will have an
`@Injectable()` decorator.
PR Close#33362
ngcc has an internal cache of computed decorator information for
reflected classes, which could previously be mutated by consumers of the
reflection host. With the ability to inject synthesized decorators, such
decorators would inadvertently be added into the array of decorators
that was owned by the internal cache of the reflection host, incorrectly
resulting in synthesized decorators to be considered real decorators on
a class. This commit fixes the issue by cloning the cached array before
returning it.

This patch ensures that the `[style]` and `[class]` based bindings
are directly applied to an element's style and className attributes.
This patch optimizes the algorithm so that it...
- Doesn't construct an update an instance of `StylingMapArray` for
`[style]` and `[class]` bindings
- Doesn't apply `[style]` and `[class]` based entries using
`classList` and `style` (direct attributes are used instead)
- Doesn't split or iterate over all string-based tokens in a
string value obtained from a `[class]` binding.
This patch speeds up the following cases:
- `<div [class]>` and `<div class="..." [class]>`
- `<div [style]>` and `<div style="..." [style]>`
The overall speec increase is by over 5x.

The template type checking abilities of the Ivy compiler are far more
advanced than the level of template type checking that was previously
done for Angular templates. Up until now, a single compiler option
called "fullTemplateTypeCheck" was available to configure the level
of template type checking. However, now that more advanced type checking
is being done, new errors may surface that were previously not reported,
in which case it may not be feasible to fix all new errors at once.
Having only a single option to disable a large number of template type
checking capabilities does not allow for incrementally addressing newly
reported types of errors. As a solution, this commit introduces some new
compiler options to be able to enable/disable certain kinds of template
type checks on a fine-grained basis.

View Engine correctly infers the type of local refs to directives or to

For elements that have a text attribute, it may happen that the element
is matched by a directive that consumes the attribute as an input. In
that case, the template type checker will validate the correctness of
the attribute with respect to the directive's declared type of the
input, which would typically be `boolean` for the `disabled` input.
Since empty attributes are assigned the empty string at runtime, the
template type checker would report an error for this template.
This commit introduces a strictness flag to help alleviate this
particular situation, effectively ignoring text attributes that happen
to be consumed by a directive.

During the creation of an Angular program in the compiler, a check is
