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.

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.

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.

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.

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

Recently it was made possible to have a directive without selector,
which are referred to as abstract directives. Such directives should not
be registered in an NgModule, but can still contain decorators for
inputs, outputs, queries, etc. The information from these decorators and
the `@Directive()` decorator itself needs to be registered with the
central `MetadataRegistry` so that other areas of the compiler can
request information about a given directive, an example of which is the
template type checker that needs to know about the inputs and outputs of
directives.
Prior to this change, however, abstract directives would only register
themselves with the `MetadataRegistry` as being an abstract directive,
without all of its other metadata like inputs and outputs. This meant
that the template type checker was unable to resolve the inputs and
outputs of these abstract directives, therefore failing to check them
correctly. The typical error would be that some property does not exist
on a DOM element, whereas said property should have been bound to the
abstract directive's input.
This commit fixes the problem by always registering the metadata of a
directive or component with the `MetadataRegistry`. Tests have been
added to ensure abstract directives are handled correctly in the
template type checker, together with tests to verify the form of
abstract directives in declaration files.

had correctly-defined absolute spans (spans relative to the entire

of a template attribute were not given an absolute span corresponding to
the start of the attribute name rather than the start of the attribute
value.
The diff on this commit is large, partially because it involves some

the following is done:
1. Move `createMeta*`-like functions from `template_parser_spec.ts` to

2. Create an `ExpressionSourceHumanizer`, similar to the one created in

of expressions' locations.
3. Create `template_parser_absolute_span_spec.ts`, testing the spans of
expressions parsed by the template parser. This is very similar to
the `r3_ast_absolute_span_spec`.

Often the types of an `@Input`'s field don't fully reflect the types of
assignable values. This can happen when an input has a getter/setter pair
where the getter always returns a narrow type, and the setter coerces a
wider value down to the narrow type.
For example, you could imagine an input of the form:
```typescript
@Input() get value(): string {
return this._value;
}
set value(v: {toString(): string}) {
this._value = v.toString();
}
```
Here, the getter always returns a `string`, but the setter accepts any value
that can be `toString()`'d, and coerces it to a string.
Unfortunately TypeScript does not actually support this syntax, and so
Angular users are forced to type their setters as narrowly as the getters,
even though at runtime the coercion works just fine.
To support these kinds of patterns (e.g. as used by Material), this commit
adds a compiler feature called "input coercion". When a binding is made to
the 'value' input of a directive like MatInput, the compiler will look for a
static field with the name ngAcceptInputType_value. If such a field is found
the type-checking expression for the input will use the static field's type
instead of the type for the @Input field,allowing for the expression of a
type conversion between the binding expression and the value being written
to the input's field.
To solve the case above, for example, MatInput might write:
```typescript
class MatInput {
// rest of the directive...
static ngAcceptInputType_value: {toString(): string};
}
```

This commit adapts the private NgModule re-export system (using aliasing) to

concern here is supporting them for commonjs-only packages.
PR Close#33177
This commit refactors the aliasing system to support multiple different
AliasingHost implementations, which control specific aliasing behavior
in ngtsc (see the README.md).
A new host is introduced, the `PrivateExportAliasingHost`. This solves a
longstanding problem in ngtsc regarding support for "monorepo" style private
libraries. These are libraries which are compiled separately from the main
application, and depended upon through TypeScript path mappings. Such
libraries are frequently not in the Angular Package Format and do not have
entrypoints, but rather make use of deep import style module specifiers.
This can cause issues with ngtsc's ability to import a directive given the
module specifier of its NgModule.
For example, if the application uses a directive `Foo` from such a library
`foo`, the user might write:
```typescript
import {FooModule} from 'foo/module';
```
In this case, foo/module.d.ts is path-mapped into the program. Ordinarily
the compiler would see this as an absolute module specifier, and assume that
the `Foo` directive can be imported from the same specifier. For such non-
APF libraries, this assumption fails. Really `Foo` should be imported from
the file which declares it, but there are two problems with this:
1. The compiler would have to reverse the path mapping in order to determine
a path-mapped path to the file (maybe foo/dir.d.ts).
2. There is no guarantee that the file containing the directive is path-
mapped in the program at all.
The compiler would effectively have to "guess" 'foo/dir' as a module
specifier, which may or may not be accurate depending on how the library and
path mapping are set up.
It's strongly desirable that the compiler not break its current invariant
that the module specifier given by the user for the NgModule is always the
module specifier from which directives/pipes are imported. Thus, for any
given NgModule from a particular module specifier, it must always be
possible to import any directives/pipes from the same specifier, no matter
how it's packaged.
To make this possible, when compiling a file containing an NgModule, ngtsc
will automatically add re-exports for any directives/pipes not yet exported
by the user, with a name of the form: ɵngExportɵModuleNameɵDirectiveName
This has several effects:
1. It guarantees anyone depending on the NgModule will be able to import its
directives/pipes from the same specifier.
2. It maintains a stable name for the exported symbol that is safe to depend
on from code on NPM. Effectively, this private exported name will be a
part of the package's .d.ts API, and cannot be changed in a non-breaking
fashion.

Static methods that return a type of ModuleWithProviders currently
do not have to specify a type because the generic falls back to any.
This is problematic because the type of the actual module being
returned is not present in the type information.
Since Ivy uses d.ts files exclusively for downstream packages
(rather than metadata.json files, for example), we no longer have
the type of the actual module being created.
For this reason, a generic type should be added for
ModuleWithProviders that specifies the module type. This will be
required for all users in v10, but will only be necessary for
users of Ivy in v9.

Previously, the `FileSystem` abstraction featured a `mkdir()` method. In
`NodeJSFileSystem` (the default `FileSystem` implementation used in
actual code), the method behaved similar to Node.js' `fs.mkdirSync()`
(i.e. failing if any parent directory is missing or the directory exists
already). In contrast, `MockFileSystem` (which is the basis or mock
`FileSystem` implementations used in tests) implemented `mkdir()` as an
alias to `ensureDir()`, which behaved more like Node.js'
`fs.mkdirSync()` with the `recursive` option set to `true` (i.e.
creating any missing parent directories and succeeding if the directory
exists already).
This commit fixes this inconsistency by removing the `mkdir()` method,
which was not used anyway and only keeping `ensureDir()` (which is
consistent across our different `FileSystem` implementations).

When `ngcc` is running in parallel mode (usually when run from the
command line) and the `createNewEntryPointFormats` option is set to true
(e.g. via the `--create-ivy-entry-points` command line option), it can
happen that two workers end up trying to create the same directory at
the same time. This can lead to a race condition, where both check for
the directory existence, see that the directory does not exist and both
try to create it, with the second failing due the directory's having
already been created by the first one. Note that this only affects
directories and not files, because `ngcc` tasks operate on different
sets of files.
This commit avoids this race condition by allowing `FileSystem`'s
`ensureDir()` method to not fail if one of the directories it is trying
to create already exists (and is indeed a directory). This is fine for
the `ensureDir()` method, since it's purpose is to ensure that the
specified directory exists. So, even if the `mkdir()` call failed
(because the directory exists), `ensureDir()` has still completed its
mission.

Often the types of an `@Input`'s field don't fully reflect the types of
assignable values. This can happen when an input has a getter/setter pair
where the getter always returns a narrow type, and the setter coerces a
wider value down to the narrow type.
For example, you could imagine an input of the form:
```typescript
@Input() get value(): string {
return this._value;
}
set value(v: {toString(): string}) {
this._value = v.toString();
}
```
Here, the getter always returns a `string`, but the setter accepts any value
that can be `toString()`'d, and coerces it to a string.
Unfortunately TypeScript does not actually support this syntax, and so
Angular users are forced to type their setters as narrowly as the getters,
even though at runtime the coercion works just fine.
To support these kinds of patterns (e.g. as used by Material), this commit
adds a compiler feature called "input coercion". When a binding is made to
the 'value' input of a directive like MatInput, the compiler will look for a
static function with the name ngCoerceInput_value. If such a function is
found, the type-checking expression for the input will be wrapped in a call
to the function, allowing for the expression of a type conversion between
the binding expression and the value being written to the input's field.
To solve the case above, for example, MatInput might write:
```typescript
class MatInput {
// rest of the directive...
static ngCoerceInput_value(value: {toString(): string}): string {
return null!;
}
}
```

As a hack to get the Ivy compiler ngtsc off the ground, the existing
'allowEmptyCodegenFiles' option was used to control generation of ngfactory
and ngsummary shims during compilation. This option was selected since it's
enabled in google3 but never enabled in external projects.
As ngtsc is now mature and the role shims play in compilation is now better
understood across the ecosystem, this commit introduces two new compiler
options to control shim generation:
* generateNgFactoryShims controls the generation of .ngfactory shims.
* generateNgSummaryShims controls the generation of .ngsummary shims.
The 'allowEmptyCodegenFiles' option is still honored if either of the above

Original description from jasonaden:
Without this change when using UrlTree redirects in urlUpdateStrategy="eager", the URL would get
updated to the target location, then redirected. This resulted in having an additional entry in the
history and thus the back button would be broken (going back would land on the URL causing a new
redirect).
Additionally, there was a bug where the redirect, even without urlUpdateStrategy="eager", could
create a history with too many entries. This was due to kicking off a new navigation within the
navigation cancelling logic. With this PR the new navigation is pushed to the next tick with a
setTimeout, allowing the page being redirected from to be cancelled before starting a new
navigation.

Now, hovering over an attribute on an element will provide information
about the directive that attribute matches in the element, if any.
(More generally, we return information about directive symbols
matched on an element attribute.)
I believe this is similar to how the indexer provides this kind of
information, though more precise in the sense that this commit provides
directive information only if the directive selector exactly matches the
attribute selector. In another sense, this is a limitation.
In fact, there are the limitations of:
- Directives matched on the element, but with a selector of anything
more than the attribute (e.g. `div[string-model]` or
`[string-model][other-attr]`) will not be returned as symbols matching
on the attribute.
- Only one symbol can be returned currently. If the attribute matches
multiple directives, only one directive symbol will be returned.
Furthermore, we cannot say that the directive symbol returned is
determinstic.
Resolution of these limitations can be discussed in the future. At least
the second limitation should be very easy to fixup in a future commit.
This relies solely on the template compiler and is agnostic to any Ivy
changes, so this is strictly a feature enhancement that will not have to
be refactored when we migrate the language service to Ivy.

Prior to this change, the template type checker would always allow a
value of type `undefined` to be passed into a directive's inputs, even
if the input's type did not allow for it. This was due to how the type
constructor for a directive was generated, where a `Partial` mapped
type was used to allow for inputs to be unset. This essentially
introduces the `undefined` type as acceptable type for all inputs.
This commit removes the `Partial` type from the type constructor, which
means that we can no longer omit any properties that were unset.
Instead, any properties that are not set will still be included in the
type constructor call, having their value assigned to `any`.

Component defs are not considered public API, so the property
that contains them should be prefixed with Angular's marker
for "private" ('ɵ') to discourage apps from relying on def
APIs directly.
This commit adds the prefix and shortens the name from
`ngComponentDef` to `cmp`. This is because property names
cannot be minified by Uglify without turning on property
mangling (which most apps have turned off) and are thus
size-sensitive.
Note that the other "defs" (ngDirectiveDef, etc) will be
prefixed and shortened in follow-up PRs, in an attempt to
limit how large and conflict-y this change is.

For v9 we want the migration to the new i18n to be as
simple as possible.
Previously the developer had to positively choose to use
legacy messsage id support in the case that their translation
files had not been migrated to the new format by setting the
`legacyMessageIdFormat` option in tsconfig.json to the format
of their translation files.
Now this setting has been changed to `enableI18nLegacyMessageFormat`

the `i18nInFormat` option, which was previously used to trigger translations
in the pre-ivy angular compiler.

Prior to this fix, whenever a style or class binding is present, the
binding application process would require an instance of `TStylingContext`
to be built regardless of whether or not any binding resolution is needed
(just so that it knows whether or not there are any collisions).
This check is, however, unnecessary because if (and only if) there
are directives present on the element then are collisions possible.
This patch removes the need for style/class bindings to register
themselves on to a `TStylingContext` if there are no directives and
present on an element. This means that all map and prop-based
style/class bindings are applied as soon as bindings are updated on
an element.

Currently the `ngForOf` input accepts `null` or `undefined` as valid
values. Although when using strict template input type checking
(which will be supported by `ngtsc`), passing `null` or `undefined`
with strict null checks enabled causes a type check failure because
the type for the `ngForOf` input becomes too strict if strict null checks
are enabled. The type of the input needs to be expanded to also accept
`null` or `undefined` to behave consistently regardless of the
`strictNullChecks` flag.
This is necessary because whenever strict input type checking is enabled
by default, most of the Angular projects that use `*ngFor` with the async pipe
will either need to disable template type checking or strict null checks
because the `async` pipe returns `null` if the observable hasn't been
emitted yet.
See for example how this affects the `angular/components` repository and
how much bloat the workaround involves: https://github.com/angular/components/pull/16373/files#r296942696.

In View Engine, animation metadata could occur in nested arrays which
would be flattened in the compiler. When compiling a component for Ivy
however, the compiler no longer statically evaluates a component's
animation metadata and is therefore unable to flatten it statically.
This resulted in an issue to find animations at runtime, as the metadata
was incorrectly registered with the animation engine.
Although it would be possible to statically evaluate the animation
metadata in ngtsc, doing so would prevent reusable animations exported
from libraries from being usable as ngtsc's partial evaluator is unable
to read values inside libraries. This is unlike ngc's usage of static
symbols represented in a library's `.metadata.json`, which explains how
the View Engine compiler is able to flatten the animation metadata
statically.
As an alternative solution, the metadata flattening is now done in the
runtime during the registration of the animation metadata with the
animation engine.

As mentioned in the previous commit, the regexp used by

This commit refactors the regexp (without changing its behavior) to make
it more closely match the format of WHATWG version, so that it is easier
for people to compare it against the WHATWG one and understand the
differences.
The main changes were:
- Changing the order of characters/character classes inside `[...]`;
e.g. `[A-Za-z]` --> `[a-zA-Z]`
- Mark all groups as non-capturing (since we do not use the captured
values); e.g. `(foo)` --> `(?:foo)`
(This could theoretically also have a positive performance impact, but
I suspect JavaScript engines are already optimizing away capturing
groups when they are not used.)

Currently the undecorated-classes-with-di migration leverages NGC in order
to work with metadata resolution. Since NGC by default tries to resolve referenced
resources on initialization of the underlying TS program, it can result in unexpected
migration failures due to missing resource files.
This is especially an issue since the CLI wraps the `AngularCompilerProgram` with
special logic (i.e. to support SCSS preprocessing etc.). We don't have all of this since
we instantiate a vanilla NGC program.
The solution to the problem is to simply treat resource requests as valid, and returning
a fake content. The migration is not dependent on templates or stylesheets.. so it's the
simplest and most robust solution.

(and doesn't get the `NgtscProgram`), we need to explicitly disable
ivy when creating the `@angular/compiler-cli` program for the migration.
This code is still relevant even though the update from version 7
to version 8 landed. Developers can run `ng update` from version 7

In an attempt to be compatible with previous translation files
the Angular compiler was generating instructions that always
included the message id. This was because it was not possible
to accurately re-generate the id from the calls to `$localize()` alone.
In line with https://hackmd.io/EQF4_-atSXK4XWg8eAha2g this
commit changes the compiler so that it only renders ids if they are
"custom" ones provided by the template author.
NOTE:
When translating messages generated by the Angular compiler
from i18n tags in templates, the `$localize.translate()` function
will compute message ids, if no custom id is provided, using a
common digest function that only relies upon the information
available in the `$localize()` calls.
This computed message id will not be the same as the message
ids stored in legacy translation files. Such files will need to be
migrated to use the new common digest function.
This only affects developers who have been trialling `$localize`, have
been calling `loadTranslations()`, and are not exclusively using custom
ids in their templates.

For reference, the extra logic mentioned above is that for injectables we have two code paths:
1. For injectables that don't configure how they should be instantiated, we create a `factory` that proxies to `ngFactoryDef`:
```
// Source
@Injectable()
class Service {}
// Output
class Service {
static ngInjectableDef = defineInjectable({
factory: () => Service.ngFactoryFn(),
});
static ngFactoryFn: (t) => new (t || Service)();
}
```
2. For injectables that do configure how they're created, we keep the `ngFactoryDef` and generate the factory based on the metadata:
```
// Source
@Injectable({
useValue: DEFAULT_IMPL,
})
class Service {}
// Output
export class Service {
static ngInjectableDef = defineInjectable({
factory: () => DEFAULT_IMPL,
});
static ngFactoryFn: (t) => new (t || Service)();

done in tsickle (https://github.com/ng-packagr/ng-packagr/pull/1401),
where only constructor parameter decorators are emitted in tsickle's
format, not any of the other decorators.
ngcc used to extract decorators from only a single format, so once it
saw the `ctorParameters` static property it assumed the library is using
the tsickle format. Therefore, none of the `__decorate` calls were

ngcc may need to insert public exports into the bundle's source as well
as to the entry-point's declaration file, as the Ivy compiler may need
to create import statements to internal library types. The way ngcc
knows which exports to add is through the references registry, to which
references to things that require a public export are added by the
various analysis steps that are executed.
One of these analysis steps is the augmentation of declaration files
where functions that return `ModuleWithProviders` are updated so that a
generic type argument is added that corresponds with the `NgModule` that
is actually imported. This type has to be publicly exported, so the
analyzer step has to add the module type to the references registry.
A problem occurs when `ModuleWithProviders` already has a generic type
argument, in which case no update of the declaration file is necessary.
This may happen when 1) ngcc is processing additional bundle formats, so
that the declaration file has already been updated while processing the
first bundle format, or 2) when a package is processed which already
contains the generic type in its source. In both scenarios it may occur
that the referenced `NgModule` type does not yet have a public export,
so it is crucial that a reference to the type is added to the
references registry, which ngcc failed to do.
This commit fixes the issue by always adding the referenced `NgModule`
type to the references registry, so that a public export will always be
created if necessary.

Before this refactoring native node `classList` / `style` properties were
read even if not used. The reason for this was desire to avoid code duplication
between procedural and non-procedural renderers. Unfortunatelly for the case
which will be used by most users (a procedura renderer) the `classList` / `style`
properties were read twice, making the `setStyle` \ `setClass` functions the
most expensive ones (self time) in several benchmarks (large table, expanding
rows).
This refactoring adds a bit of code duplication in order to get better
runtime performance. The code duplication will be removed when we drop
checks for a procedural renderer.

Currently the expressions used in a template string are automatically named
`PH_1`, `PH_2`, etc. Whereas interpolations used in i18n templates generate
placeholders automatically named `INTERPOLATION`, `INTERPOLATION_1`, etc.
This commit aligns the behaviors by starting the generated placeholder
names for expressions at `PH`, then `PH_1`, etc.
It also documents this behavior in the documentation of `$localize` as
it was not mentioned before.

Now that the `$localize` translations are `MessageId` based the
compiler must render `MessageId`s in its generated `$localize` code.
This is because the `MessageId` used by the compiler is computed
from information that does not get passed through to the `$localize`
tagged string.
For example, the generated code for the following template
```html
<div id="static" i18n-title="m|d" title="introduction"></div>
```
will contain these localization statements
```ts
if (ngI18nClosureMode) {
/**
* @desc d
* @meaning m
*/
const MSG_EXTERNAL_8809028065680254561$$APP_SPEC_TS_1 = goog.getMsg("introduction");
I18N_1 = MSG_EXTERNAL_8809028065680254561$$APP_SPEC_TS_1;
}
else {
I18N_1 = $localize \`:m|d@@8809028065680254561:introduction\`;
}
```
Since `$localize` is not able to accurately regenerate the source-message
(and so the `MessageId`) from the generated code, it must rely upon the
`MessageId` being provided explicitly in the generated code.
The compiler now prepends all localized messages with a "metadata block"
containing the id (and the meaning and description if defined).
Note that this metadata block will also allow translation file extraction
from the compiled code - rather than relying on the legacy ViewEngine
extraction code. (This will be implemented post-v9).
Although these metadata blocks add to the initial code size, compile-time
inlining will completely remove these strings and so will not impact on
production bundle size.

As discussed in https://hackmd.io/33M5Wb-JT7-0fneA0JuHPA `SourceMessage`
strings are not sufficient for matching translations.
This commit updates `@angular/localize` to use `MessageId`s for translation
matching instead.
Also the run-time translation will now log a warning to the console if a
translation is missing.

Translations (loaded via the `loadTranslations()` function) must now use
`MessageId` for the translation key rather than the previous `SourceMessage`
string.

Previously the translation key used for translations was the `SourceMessage`

Within an Angular package, it can happen that there are
entry-points which do not contain features that belong into
an `@NgModule` or need metadata files to be generated.
For example: the `cdk`, `cdk/testing` and `cdk/coercion`
entry-points. Besides other entry-points in the `cdk`
package, those entry-points do not need metadata to
be generated and no not use the `ng_module` rule.
Currently the "ng_package" rule properly picks up such
entry-points and builds bundles, does downleveling etc.
The only thing it misses is that no `package.json` files
are generated for the entry-point. This means that consumers
will not be able to use these entry-points built with "ts_library"
(except accessing the individual bundlings explicitly).
The "ng_package" rule should follow the full APF specification
for such entry-points. Partially building bundles and doing the
downleveling is confusing and a breaking issue.
The motifivation of supporting this (besides making the
rule behavior consistent; the incomplete output is not
acceptable), is that using the "ng_module" rule does
not make sense to be used for non-Angular entry-points.
Especially since it depends on Angular packages to
be specified as Bazel action inputs just to compile
vanilla TypeScript with `@angular/compiler-cli`.

This is a refactoring that moves the source code around to provide a better
platform for adding the compile-time inlining.
1. Move the global side-effect import from the primary entry-point to a
secondary entry-point @angular/localize/init.
This has two benefits: first it allows the top level entry-point to
contain tree-shakable shareable code; second it gives the side-effect
import more of an "action" oriented name, which indicates that importing
it does something tangible
2. Move all the source code into the top src folder, and import the localize
related functions into the localize/init/index.ts entry-point.
This allows the different parts of the package to share code without
a proliferation of secondary entry-points (i.e. localize/utils).
3. Avoid publicly exporting any utilities at this time - the only public
API at this point are the global `$localize` function and the two runtime
helpers `loadTranslations()` and `clearTranslations()`.
This does not mean that we will not expose additional helpers for 3rd
party tooling in the future, but it avoid us preemptively exposing
something that we might want to change in the near future.
Notes:
It is not possible to have the `$localize` code in the same Bazel package
as the rest of the code. If we did this, then the bundled `@angular/localize/init`
entry-point code contains all of the helper code, even though most of it is not used.
Equally it is not possible to have the `$localize` types (i.e. `LocalizeFn`
and `TranslateFn`) defined in the `@angular/localize/init` entry-point because
these types are needed for the runtime code, which is inside the primary
entry-point. Importing them from `@angular/localize/init` would run the
side-effect.
The solution is to have a Bazel sub-package at `//packages/localize/src/localize`
which contains these types and the `$localize` function implementation.
The primary `//packages/localize` entry-point imports the types without
any side-effect.
The secondary `//packages/localize/init` entry-point imports the `$localize`
function and attaches it to the global scope as a side-effect, without
bringing with it all the other utility functions.
BREAKING CHANGES:
The entry-points have changed:
* To attach the `$localize` function to the global scope import from
`@angular/localize/init`. Previously it was `@angular/localize`.
* To access the `loadTranslations()` and `clearTranslations()` functions,
import from `@angular/localize`. Previously it was `@angular/localize/run_time`.

PR Close#32645
In ngcc's reflection host for UMD and CommonJS bundles, custom logic is
present to resolve import details of an identifier. However, this custom
logic is unable to resolve an import for an identifier inside of
declaration files, as such files use the regular ESM import syntax.
As a consequence of this limitation, ngtsc is unable to resolve
`ModuleWithProviders` imports that are declared in an external library.
In that situation, ngtsc determines the type of the actual `NgModule`
that is imported, by looking in the library's declaration files for the
generic type argument on `ModuleWithProviders`. In this process, ngtsc
resolves the import for the `ModuleWithProviders` identifier to verify
that it is indeed the `ModuleWithProviders` type from `@angular/core`.
So, when the UMD reflection host was in use this resolution would fail,
therefore no `NgModule` type could be detected.
This commit fixes the bug by using the regular import resolution logic
in addition to the custom resolution logic that is required for UMD
and CommonJS bundles.

In ESM2015 bundles, a class with decorators may be emitted as follows:
```javascript
var MyClass_1;
let MyClass = MyClass_1 = class MyClass {};
MyClass.decorators = [/* here be decorators */];
```
Such a class has two declarations: the publicly visible `let MyClass`
and the implementation `class MyClass {}` node. In #32539 a refactoring
took place to handle such classes more consistently, however the logic
to find static properties was mistakenly kept identical to its broken
state before the refactor, by looking for static properties on the
implementation symbol (the one for `class MyClass {}`) whereas the
static properties need to be obtained from the symbol corresponding with
the `let MyClass` declaration, as that is where the `decorators`
property is assigned to in the example above.
This commit fixes the behavior by looking for static properties on the
public declaration symbol. This fixes an issue where decorators were not
found for classes that do in fact have decorators, therefore preventing
the classes from being compiled for Ivy.

In ngcc's reflection hosts for compiled JS bundles, such as ESM2015,
special care needs to be taken for classes as there may be an outer
declaration (referred to as "declaration") and an inner declaration
(referred to as "implementation") for a given class. Therefore, there
will also be two `ts.Symbol`s bound per class, and ngcc needs to switch
between those declarations and symbols depending on where certain
information can be found.
Prior to this commit, the `NgccReflectionHost` interface had methods
`getClassSymbol` and `findClassSymbols` that would return a `ts.Symbol`.
These class symbols would be used to kick off compilation of components
using ngtsc, so it is important for these symbols to correspond with the
publicly visible outer declaration of the class. However, the ESM2015
reflection host used to return the `ts.Symbol` for the inner
declaration, if the class was declared as follows:
```javascript
var MyClass = class MyClass {};
```
For the above code, `Esm2015ReflectionHost.getClassSymbol` would return
the `ts.Symbol` corresponding with the `class MyClass {}` declaration,
whereas it should have corresponded with the `var MyClass` declaration.
As a consequence, no `NgModule` could be resolved for the component, so
no components/directives would be in scope for the component. This
resulted in errors during runtime.
This commit resolves the issue by introducing a `NgccClassSymbol` that
contains references to both the outer and inner `ts.Symbol`, instead of
just a single `ts.Symbol`. This avoids the unclarity of whether a
`ts.Symbol` corresponds with the outer or inner declaration.

`ngcc` supports both synchronous and asynchronous execution. The default

Previously, the work would be executed in the same way in both modes.
This commit improves the performance of `ngcc` in async mode by

built-in [`cluster` module](https://nodejs.org/api/cluster.html) to
launch a cluster of Node.js processes and take advantage of multi-core
systems.
Preliminary comparisons indicate a 1.8x to 2.6x speed improvement when

better understand these numbers and identify potential areas of
improvement.

Previously, `ngcc` needed to store some metadata related to the
processing of each entry-point. This metadata was stored in a `Map`, in
the form of `EntryPointProcessingMetadata` and passed around as needed.
After some recent refactorings, it turns out that this metadata (with
its only remaining property, `hasProcessedTypings`) was no longer used,

In the past, a task's processability didn't use to be known in advance.
It was possible that a task would be created and added to the queue
during the analysis phase and then later (during the compilation phase)
it would be found out that the task (i.e. the associated format
property) was not processable.
As a result, certain checks had to be delayed, until a task's processing
had started or even until all tasks had been processed. Examples of
checks that had to be delayed are:
- Whether a task can be skipped due to `compileAllFormats: false`.
- Whether there were entry-points for which no format at all was
successfully processed.
It turns out that (as made clear by the refactoring in 9537b2ff8), once
a task starts being processed it is expected to either complete
successfully (with the associated format being processed) or throw an
error (in which case the process will exit). In other words, a task's
processability is known in advance.
This commit takes advantage of this fact by moving certain checks
earlier in the process (e.g. in the analysis phase instead of the
compilation phase), which in turn allows avoiding some unnecessary work.
More specifically:
- When `compileAllFormats` is `false`, tasks are created _only_ for the
first suitable format property for each entry-point, since the rest of
the tasks would have been skipped during the compilation phase anyway.
This has the following advantages:
1. It avoids the slight overhead of generating extraneous tasks and
then starting to process them (before realizing they should be
skipped).
2. In a potential future parallel execution mode, unnecessary tasks
might start being processed at the same time as the first (useful)
task, even if their output would be later discarded, wasting
resources. Alternatively, extra logic would have to be added to
prevent this from happening. The change in this commit avoids these
issues.
- When an entry-point is not processable, an error will be thrown
upfront without having to wait for other tasks to be processed before
failing.

Previously, `ngcc`'s programmatic API would run and complete
synchronously. This was necessary for specific usecases (such as how the
`@angular/cli` invokes `ngcc` as part of the TypeScript module
resolution process), but not for others (e.g. running `ivy-ngcc` as a
`postinstall` script).
This commit adds a new option (`async`) that enables turning on
asynchronous execution. I.e. it signals that the caller is OK with the
function call to complete asynchronously, which allows `ngcc` to
potentially run in a more efficient mode.
Currently, there is no difference in the way tasks are executed in sync
vs async mode, but this change sets the ground for adding new execution
options (that require asynchronous operation), such as processing tasks
in parallel on multiple processes.
NOTE:
When using the programmatic API, the default value for `async` is
`false`, thus retaining backwards compatibility.
When running `ngcc` from the command line (i.e. via the `ivy-ngcc`
script), it runs in async mode (to be able to take advantage of future
optimizations), but that is transparent to the caller.

The issue comes from the fact that we choose the `ng-container` comment node as the anchor point before which to insert the content, however the node might be after any of the nodes inside the container. These changes switch to picking out the first node inside of the container instead.

Historically bind() used to be a separate instruction. With a series of
refactoring it became a utility function but after recent code changes
it does not provide any valuable abstraction / help. On the contrary -
it can be seen as a performance problem (forces unnecessary comparison to
`NO_CHANGE` during change detection).

Prior to this commit, complex expressions (that require additional statements to be generated) were handled incorrectly in case they were used in attributes annotated with i18n flags. The problem was caused by the fact that extra statements were not appended to the temporary vars block, so they were missing in generated code. This commit updated the logic to use the `convertPropertyBinding`, which contains the necessary code to append extra statements. The `convertExpressionBinding` function was removed as it duplicates the `convertPropertyBinding` one (for the most part) and is no longer used.

Previously, when the ServiceWorker entered a degraded mode
(`EXISTING_CLIENTS_ONLY` or `SAFE_MODE`) it would remain in that mode
for the rest of the lifetime of ServiceWorker instance. Note that
ServiceWorkers are stopped by the browser after a certain period of
inactivity and a new instance is created as soon as the ServiceWorker
needs to handle an event (such as a request from the page). Those new
instances would start from the `NORMAL` mode.
The reason for this behavior is to err on the side of caution: If we
can't be sure why the ServiceWorker entered the degraded mode, it is
risky to try recovering on the same instance and might lead to
unexpected behavior.
However, it turns out that the `EXISTING_CLIENTS_ONLY` mode can only be
a result of some error happening with the latest version (e.g. a hash
mismatch in the manifest). Therefore, it is safe to recover from that
mode once a new, valid update is successfully installed and to start
accepting new clients.
This commit ensures that the mode is set back to `NORMAL`, when (a) an
update is successfully installed and (b) the current mode is
`EXISTING_CLIENTS_ONLY`.
Besides making the behavior more predictable (instead of relying on the
browser to decide when to terminate the current ServiceWorker instance
and create a new one), this change can also improve the developer
experience:
When people notice the error during debugging and fix it by deploying a
new version (either to production or locally), it is confusing that the
ServiceWorker will fetch and install the update (as seen by the requests
in the Network panel in DevTools) but not serve it to clients. With this
change, the update will be served to new clients as soon as it is
installed.

Previously, when the latest version was invalidated (e.g. due to a hash
mismatch), the SW entered a degraded `EXISTING_CLIENTS_ONLY` mode and
removed _all_ clients from its client-version map (essentially stopping
to serve any clients). Based on the code and surrounding comments, the

Since `$localize` is a global function, it must be included in any applications
that use i18n. This is achieved by importing the `@angular/localize` package
into an appropriate bundle, where it will be executed before the renderer
needs to call `$localize`. For CLI based projects, this is best done in
the `polyfills.ts` file.

Previously, the emulated Windows mode would normalize rooted paths to

When ngcc is called for a specific entry-point, it has to determine
which dependencies to transitively process. To accomplish this, ngcc
traverses the full import graph of the entry-points it encounters, for
which it uses a dependency host to find all module imports. Since
imports look different in the various bundle formats ngcc supports, a
specific dependency host is used depending on the information provided
in an entry-points `package.json` file. If there's not enough
information in the `package.json` file for ngcc to be able to determine
which dependency host to use, ngcc would fail with an error.
If, however, the entry-point is not compiled by Angular, it is not
necessary to process any of its dependencies. None of them can have
been compiled by Angular so ngcc does not need to know about them.
Therefore, this commit changes the behavior to avoid recursing into
dependencies of entry-points that are not compiled by Angular.
In particular, this fixes an issue for packages that have dependencies
on the `date-fns` package. This package has various secondary
entry-points that have a `package.json` file only containing a `typings`
field, without providing additional fields for ngcc to know which
dependency host to use. By not needing a dependency host at all, the
error is avoided.

In ngc is was valid to set the "flatModuleOutFile" option to "null". This is sometimes
necessary if a tsconfig extends from another one but the "fatModuleOutFile" option
needs to be unset (note that "undefined" does not exist as value in JSON)
Now if ngtsc is used to compile the project, ngtsc will fail with an error because it
tries to do string manipulation on the "flatModuleOutFile". This happens because
ngtsc only skips flat module indices if the option is set to "undefined".
Since this is not compatible with what was supported in ngc and such exceptions
should be avoided, the flat module check is now aligned with ngc.

Historically, the Angular Compiler has produced both native TypeScript
diagnostics (called ts.Diagnostics) and its own internal Diagnostic format
(called an api.Diagnostic). This was done because TypeScript ts.Diagnostics
cannot be produced for files not in the ts.Program, and template type-
checking diagnostics are naturally produced for external .html template
files.
This design isn't optimal for several reasons:
1) Downstream tooling (such as the CLI) must support multiple formats of
diagnostics, adding to the maintenance burden.
2) ts.Diagnostics have gotten a lot better in recent releases, with support
for suggested changes, highlighting of the code in question, etc. None of
these changes have been of any benefit for api.Diagnostics, which have
continued to be reported in a very primitive fashion.
3) A future plugin model will not support anything but ts.Diagnostics, so
generating api.Diagnostics is a blocker for ngtsc-as-a-plugin.
4) The split complicates both the typings and the testing of ngtsc.
To fix this issue, this commit changes template type-checking to produce
ts.Diagnostics instead. Instead of reporting a special kind of diagnostic
for external template files, errors in a template are always reported in
a ts.Diagnostic that highlights the portion of the template which contains
the error. When this template text is distinct from the source .ts file
(for example, when the template is parsed from an external resource file),
additional contextual information links the error back to the originating
component.
A template error can thus be reported in 3 separate ways, depending on how
the template was configured:
1) For inline template strings which can be directly mapped to offsets in
the TS code, ts.Diagnostics point to real ranges in the source.
This is the case if an inline template is used with a string literal or a
"no-substitution" string. For example:
```typescript
@Component({..., template: `
<p>Bar: {{baz}}</p>
`})
export class TestCmp {
bar: string;
}
```
The above template contains an error (no 'baz' property of `TestCmp`). The
error produced by TS will look like:
```
<p>Bar: {{baz}}</p>
~~~
test.ts:2:11 - error TS2339: Property 'baz' does not exist on type 'TestCmp'. Did you mean 'bar'?
```
2) For template strings which cannot be directly mapped to offsets in the
TS code, a logical offset into the template string will be included in
the error message. For example:
```typescript
const SOME_TEMPLATE = '<p>Bar: {{baz}}</p>';
@Component({..., template: SOME_TEMPLATE})
export class TestCmp {
bar: string;
}
```
Because the template is a reference to another variable and is not an
inline string constant, the compiler will not be able to use "absolute"
positions when parsing the template. As a result, errors will report logical
offsets into the template string:
```
<p>Bar: {{baz}}</p>
~~~
test.ts (TestCmp template):2:15 - error TS2339: Property 'baz' does not exist on type 'TestCmp'.
test.ts:3:28
@Component({..., template: TEMPLATE})
~~~~~~~~
Error occurs in the template of component TestCmp.
```
This error message uses logical offsets into the template string, and also
gives a reference to the `TEMPLATE` expression from which the template was
parsed. This helps in locating the component which contains the error.
3) For external templates (templateUrl), the error message is delivered
within the HTML template file (testcmp.html) instead, and additional
information contextualizes the error on the templateUrl expression from
which the template file was determined:
```
<p>Bar: {{baz}}</p>
~~~
testcmp.html:2:15 - error TS2339: Property 'baz' does not exist on type 'TestCmp'.
test.ts:10:31
@Component({..., templateUrl: './testcmp.html'})
~~~~~~~~~~~~~~~~
Error occurs in the template of component TestCmp.

Previously, `ngcc` assumed that if a format property was defined in

requested file to an actual location on disk, by testing various
extensions. For recursive calls however, the path is known to have been
resolved in the module resolver. Therefore, it is safe to move the path
resolution to the initial caller into the recursive process.
Note that this is not expected to improve the performance of ngcc, as
the call to `resolveFileWithPostfixes` is known to succeed immediately,
as the provided path is known to exist without needing to add any
postfixes. Furthermore, the FileSystem caches whether files exist, so
the additional check that we used to do was cheap.

ngcc needs to solve a unique problem when compiling typings for an
entrypoint: it must resolve a declaration within a .js file to its
representation in a .d.ts file. Since such .d.ts files can be used in deep
imports without ever being referenced from the "root" .d.ts, it's not enough
to simply match exported types to the root .d.ts. ngcc must build an index
of all .d.ts files.
Previously, this operation had a bug: it scanned all .d.ts files in the
.d.ts program, not only those within the package. Thus, if a class in the
program happened to share a name with a class exported from a dependency's
.d.ts, ngcc might accidentally modify the wrong .d.ts file, causing a
variety of issues downstream.
To fix this issue, ngcc's .d.ts scanner now limits the .d.ts files it
indexes to only those declared in the current package.

One of the compiler's tasks is to enumerate the exports of a given ES
module. This can happen for example to resolve `foo.bar` where `foo` is a
namespace import:
```typescript
import * as foo from './foo';
@NgModule({
directives: [foo.DIRECTIVES],
})
```
In this case, the compiler must enumerate the exports of `foo.ts` in order
to evaluate the expression `foo.DIRECTIVES`.
When this operation occurs under ngcc, it must deal with the different
module formats and types of exports that occur. In commonjs code, a problem
arises when certain exports are downleveled.
```typescript
export const DIRECTIVES = [
FooDir,
BarDir,
];
```
can be downleveled to:
```javascript
exports.DIRECTIVES = [
FooDir,
BarDir,
```
Previously, ngtsc and ngcc expected that any export would have an associated
`ts.Declaration` node. `export class`, `export function`, etc. all retain
`ts.Declaration`s even when downleveled. But the `export const` construct
above does not. Therefore, ngcc would not detect `DIRECTIVES` as an export
of `foo.ts`, and the evaluation of `foo.DIRECTIVES` would therefore fail.
To solve this problem, the core concept of an exported `Declaration`
according to the `ReflectionHost` API is split into a `ConcreteDeclaration`
which has a `ts.Declaration`, and an `InlineDeclaration` which instead has
a `ts.Expression`. Differentiating between these allows ngcc to return an
`InlineDeclaration` for `DIRECTIVES` and correctly keep track of this
export.

In VE the `Sanitizer` is always available in `BrowserModule` because the VE retrieves it using injection.
In Ivy the injection is optional and we have instructions instead of component definition arrays. The implication of this is that in Ivy the instructions can pull in the sanitizer only when they are working with a property which is known to be unsafe. Because the Injection is optional this works even if no Sanitizer is present. So in Ivy we first use the sanitizer which is pulled in by the instruction, unless one is available through the `Injector` then we use that one instead.
This PR does few things:
1) It makes `Sanitizer` optional in Ivy.
2) It makes `DomSanitizer` tree shakable.
3) It aligns the semantics of Ivy `Sanitizer` with that of the Ivy sanitization rules.
4) It refactors `DomSanitizer` to use same functions as Ivy sanitization for consistency.

In Angular today, the following pattern works:
```typescript
export class BaseDir {
constructor(@Inject(ViewContainerRef) protected vcr: ViewContainerRef) {}
}
@Directive({
selector: '[child]',

export class ChildDir extends BaseDir {

A decorated child class can inherit a constructor from an undecorated base
class, so long as the base class has metadata of its own (for JIT mode).
This pattern works regardless of metadata in AOT.
In Angular Ivy, this pattern does not work: without the @Directive
annotation identifying the base class as a directive, information about its
constructor parameters will not be captured by the Ivy compiler. This is a
result of Ivy's locality principle, which is the basis behind a number of
compilation optimizations.
As a solution, @Directive() without a selector will be interpreted as a
"directive base class" annotation. Such a directive cannot be declared in an
NgModule, but can be inherited from. To implement this, a few changes are
made to the ngc compiler:
* the error for a selector-less directive is now generated when an NgModule
declaring it is processed, not when the directive itself is processed.
* selector-less directives are not tracked along with other directives in
the compiler, preventing other errors (like their absence in an NgModule)

This commit avoids the unnecessary operations by entirely skipping
subsequent properties, once the first one has been successfully

Any decorator information present in TypeScript is emitted into the
generated JavaScript sources by means of `__decorate` call. This call
contains both the decorators as they existed in the original source
code, together with calls to `tslib` helpers that convey additional
information on e.g. type information and parameter decorators. These
different kinds of decorator calls were not previously distinguished on
their own, but instead all treated as `Decorator` by themselves. The
"decorators" that were actually `tslib` helper calls were conveniently
filtered out because they were not imported from `@angular/core`, a
characteristic that ngcc uses to drop certain decorators.
Note that this posed an inconsistency in ngcc when it processes
`@angular/core`'s UMD bundle, as the `tslib` helper functions have been
inlined in said bundle. Because of the inlining, the `tslib` helpers
appear to be from `@angular/core`, so ngcc would fail to drop those
apparent "decorators". This inconsistency does not currently cause any
issues, as ngtsc is specifically looking for decorators based on their
name and any remaining decorators are simply ignored.
This commit rewrites the decorator analysis of a class to occur all in a
single phase, instead of all throughout the `ReflectionHost`. This
allows to categorize the various decorate calls in a single sweep,
instead of constantly needing to filter out undesired decorate calls on

In ViewEngine nodes that were inserted through `Renderer2` would also be picked up by `DebugNode.query` and `DebugNode.queryAll`. This worked because everything in ViewEngine went through `Renderer2` and `DebugRenderer2` in dev mode which was able to keep track of the child nodes as they're being inserted. This no longer works in Ivy, because we don't use `DebugRenderer2` and debug nodes work a little differently. These changes work around the issue by walking the DOM as the logical tree is being walked and looking for matches. Note that this is __not__ optimal, because we're walking similar trees multiple times. ViewEngine could do it more efficiently, because all the insertions go through Renderer2, however that's not the case in Ivy. This approach is being used because:
1. Matching the ViewEngine behavior would mean potentially introducing a depedency from `Renderer2` to Ivy which could bring Ivy code into ViewEngine.
2. We would have to make `Renderer3` "know" about debug nodes.
3. It allows us to capture nodes that were inserted directly via the DOM.

Currently developers can use the `By` class to construct common
`DebugElement` query predicates. e.g. `By.directive(MyDirective)`.
The `directive()` and `all()` predicates are currently returning
a predicate that works for `DebugElement` nodes. This return type
is too strict since the predicate is not specific to `DebugElement`
instances and can also apply to `DebugNode` instances.
Meaning that developers are currently able to use the `directive()`
predicate when using `queryAllNodes()`. This is a common practice
but will break when the project is compiled with TypeScript's
`--strictFunctionTypes` flag as the `DebugElement` predicate type
is not assignable to predicates for `DebugNode`. In order to make

Currently we reuse the same instruction both for regular property bindings and property bindings on the `host`. The only difference between the two is that when it's on the host we shouldn't support inputs. We have an optional parameter called `nativeOnly` which is used to differentiate the two, however since `nativeOnly` is preceeded by another optional parameter (`sanitizer`), we have to generate two extra parameters for each host property bindings every time (e.g. `property('someProp', 'someValue', null, true)`).
These changes add a new instruction called `hostProperty` which avoids the need for the two parameters by removing `nativeOnly` which is always set and it allows us to omit `sanitizer` when it isn't being used.
These changes also remove the `nativeOnly` parameter from the `updateSyntheticHostBinding` instruction, because it's only generated for host elements which means that we can assume that its value will always be `true`.

There are two places in the ngcc processing where it needs to load the
content of a file given by a general path:
* when determining the format of an entry-point.
To do this ngcc uses the value of the relevant property in package.json.
But in the case of `main` it must parse the contents of the entry-point
file to decide whether the format is UMD or CommonJS.
* when parsing the source files for dependencies to determine the order in
which compilation must occur. The relative imports in each file are parsed
and followed recursively, looking for external imports.
Previously, we naively assumed that the path would match the file name exactly.
But actually we must consider the standard module resolution conventions.
E.g. the extension (.js) may be missing, or the path may refer to a directory
containing an index.js file.
This commit fixes both places.
This commit now requires the `DependencyHost` instances to check
the existence of more files than before (at worst all the different possible
post-fixes). This should not create a significant performance reduction for
ngcc. Since the results of the checks will be cached, and similar work is
done inside the TS compiler, so what we lose in doing it here, is saved later
in the processing. The main performance loss would be where there are lots
of files that need to be parsed for dependencies that do not end up being
processed by TS. But compared to the main ngcc processing this dependency
parsing is a small proportion of the work done and so should not impact
much on the overall performance of ngcc.

When profiling ngcc it is notable that a large amount of time
is spent dealing with an exception that is thrown (and handled
internally by fs) when checking the existence of a file.
We check file existence a lot in both finding entry-points
and when TS is compiling code. This commit adds a simple
cached `FileSystem`, which wraps a real `FileSystem` delegate.
This will reduce the number of calls through to `fs.exists()` and
`fs.readFile()` on the delegate.
Initial benchmarks indicate that the cache is miss to hit ratio
for `exists()` is about 2:1, which means that we save about 1/3
of the calls to `fs.existsSync()`.
Note that this implements a "non-expiring" cache, so it is not suitable
for a long lived `FileSystem`, where files may be modified externally.
The cache will be updated if a file is changed or moved via
calls to `FileSystem` methods but it will not be aware of changes
to the files system from outside the `FileSystem` service.
For ngcc we must create a new `FileSystem` service
for each run of `mainNgcc` and ensure that all file operations
(including TS compilation) use the `FileSystem` service.
This ensures that it is very unlikely that a file will change
externally during `mainNgcc` processing.

There's a testcase in the compiler that verifies that all such facade types
are compatible across core and compiler, such that the core types can't get
misaligned with the actual definitions in the compiler. This suite of
tests were missing the `R3BaseMetadataFacade` facade type, so it was possible
for this type to get out of sync.

When a class uses Angular decorators such as `@Input`, `@Output` and
friends without an Angular class decorator, they are compiled into a
static `ngBaseDef` field on the class, with the TypeScript declaration
of the class being altered to declare the `ngBaseDef` field to be of type
`ɵɵBaseDef`. This type however requires a generic type parameter that
corresponds with the type of the class, however the compiler did not
provide this type parameter. As a result, compiling a program where such
invalid `ngBaseDef` declarations are present will result in compilation
errors.
This commit fixes the problem by providing the generic type parameter.

Without this change when using UrlTree redirects in `urlUpdateStrategy="eager"`, the URL would get updated to the target location, then redirected. This resulted in having an additional entry in the `history` and thus the `back` button would be broken (going back would land on the URL causing a new redirect).
Additionally, there was a bug where the redirect, even without `urlUpdateStrategy="eager"`, could create a history with too many entries. This was due to kicking off a new navigation within the navigation cancelling logic. With this PR the new navigation is pushed to the next tick with a `setTimeout`, allowing the page being redirected from to be cancelled before starting a new navigation.

Currently in Ivy whenever we encounter a new namespace, we set it in the global state so that all subsequent nodes are created under the same namespace. Next time a template is run the namespace will be reset back to HTML.
This breaks down if the last node that was rendered was under the SVG or MathML namespace and we create a component through `ViewContainerRef.create`, because the next template function hasn't run yet and it hasn't had the chance to update the namespace. The result is that the root node of the new component will retain the wrong namespace and may not end up rendering at all (e.g. if we're trying to show a `div` inside the SVG namespace). This issue has the potential to affect a lot of apps, because all components inserted through the router also go through `ViewContainerRef.create`.

The Angular runtime frequently calls into user code (for example, when
writing to a property binding). Since user code can throw errors, calls to
it are frequently wrapped in a try-finally block. In Ivy, the following
pattern is common:
```typescript
enterView();
try {
callUserCode();
} finally {
leaveView();
}
```
This has a significant problem, however: `leaveView` has a side effect: it
calls any pending lifecycle hooks that might've been scheduled during the
current round of change detection. Generally it's a bad idea to run
lifecycle hooks after the application has crashed. The application is in an
inconsistent state - directives may not be instantiated fully, queries may
not be resolved, bindings may not have been applied, etc. Invariants that
the app code relies upon may not hold. Further crashes or broken behavior
are likely.
Frequently, lifecycle hooks are used to make assertions about these
invariants. When these assertions fail, they will throw and "swallow" the
original error, making debugging of the problem much more difficult.
This commit modifies `leaveView` to understand whether the application is
currently crashing, via a parameter `safeToRunHooks`. This parameter is set
by modifying the above pattern:
```typescript
enterView();
let safeToRunHooks = false;
try {
callUserCode();
safeToRunHooks = true;
} finally {
leaveView(..., safeToRunHooks);
}
```
If `callUserCode` crashes, then `safeToRunHooks` will never be set to `true`
and `leaveView` won't call any further user code. The original error will
then propagate back up the stack and be reported correctly. A test is added
to verify this behavior.

Our module resolution prefers `.js` files over `.d.ts` files because
occasionally libraries publish their typings in the same directory
structure as the compiled JS files, i.e. adjacent to each other.
The standard TS module resolution would pick up the typings
file and add that to the `ts.Program` and so they would be
ignored by our analyzers. But we need those JS files, if they
are part of the current package.
But this meant that we also bring in JS files from external
imports from outside the package, which is not desired.
This was happening for the `@fire/storage` enty-point
that was importing the `firebase/storage` path.
In this commit we solve this problem, for the case of imports
coming from a completely different package, by saying that any
file that is outside the package root directory must be an external
import and so we do not analyze those files.
This does not solve the potential problem of imports between
secondary entry-points within a package but so far that does
not appear to be a problem.

There are scenarios where it is not possible for ngcc to guess the format

there is an entry-point when there should not be one.
2) Deep-import entry-points: some packages allow deep-imports but do not
provide package.json files to indicate to ngcc that the imported path is
actually an entry-point to be processed.
3) Invalid/missing package.json properties: For example, an entry-point
that does not provide a valid property to a required format.
The configuration is provided by one or more `ngcc.config.js` files:
* If placed at the root of the project, this file can provide configuration
for named packages (and their entry-points) that have been npm installed
into the project.
* If published as part of a package, the file can provide configuration
for entry-points of the package.

To improve cross platform support, all file access (and path manipulation)
is now done through a well known interface (`FileSystem`).
For testing a number of `MockFileSystem` implementations are provided.
These provide an in-memory file-system which emulates operating systems
like OS/X, Unix and Windows.
The current file system is always available via the static method,
`FileSystem.getFileSystem()`. This is also used by a number of static
methods on `AbsoluteFsPath` and `PathSegment`, to avoid having to pass
`FileSystem` objects around all the time. The result of this is that one
must be careful to ensure that the file-system has been initialized before
using any of these static methods. To prevent this happening accidentally
the current file system always starts out as an instance of `InvalidFileSystem`,
which will throw an error if any of its methods are called.
You can set the current file-system by calling `FileSystem.setFileSystem()`.
During testing you can call the helper function `initMockFileSystem(os)`
which takes a string name of the OS to emulate, and will also monkey-patch
aspects of the TypeScript library to ensure that TS is also using the
current file-system.
Finally there is the `NgtscCompilerHost` to be used for any TypeScript
compilation, which uses a given file-system.
All tests that interact with the file-system should be tested against each
of the mock file-systems. A series of helpers have been provided to support
such tests:
* `runInEachFileSystem()` - wrap your tests in this helper to run all the
wrapped tests in each of the mock file-systems.
* `addTestFilesToFileSystem()` - use this to add files and their contents
to the mock file system for testing.
* `loadTestFilesFromDisk()` - use this to load a mirror image of files on
disk into the in-memory mock file-system.
* `loadFakeCore()` - use this to load a fake version of `@angular/core`
into the mock file-system.

To provide some context: The implicit receiver is part of the
parsed Angular template AST. Any property reads in bindings,
interpolations etc. read from a given object (usually the component
instance). In that case there is an _implicit_ receiver which can also
be specified explicitly by just using `this`.
e.g.
```html
<ng-template>{{this.myProperty}}</ng-template>
```
This works as expected in Ivy and View Engine, but breaks in case the
implicit receiver is not used for property reads. For example:
```html
<my-dir [myFn]="greetFn.bind(this)"></my-dir>
```
In that case the `this` will not be properly translated into the generated
template function code because the Ivy compiler currently always treats
the `ctx` variable as the implicit receiver. This is **not correct** and breaks
compatibility with View Engine. Rather we need to ensure that we retrieve
the root context for the standalone implicit receiver similar to how it works
for property reads (as seen in the example above with `this.myProperty`)
Note that this requires some small changes to the `expression_converter`
because we only want to generate the `eenextContent()` instruction if the
implicit receiver is _actually_ used/needed. View Engine determines if that is the case by recursively walking through the converted output AST and
checking for usages of the `o.variable('_co')` variable ([see here][ve_check]). This would work too for Ivy, but involves most likely more code duplication
since templates are isolated in different functions and it another pass
through the output AST for every template expression.

Currently undecorated classes are intentionally not processed
with ngcc. This is causing unexpected behavior because decorator
handlers such as `base_def.ts` are specifically interested in class
definitions without top-level decorators, so that the base definition
can be generated if there are Angular-specific class members.
In order to ensure that undecorated base-classes work as expected
with Ivy, we need to run the decorator handlers for all top-level
class declarations (not only for those with decorators). This is similar
to when `ngtsc` runs decorator handlers when analyzing source-files.

A custom foreign function resolver is not sufficient in this case, as

With View engine it was possible to declare multiple projection
definitions and to programmatically project nodes into the slots.
e.g.
```html
<ng-content></ng-content>
<ng-content></ng-content>
```
Using `ViewContainerRef#createComponent` allowed projecting
nodes into one of the projection defs (through index)
This no longer works with Ivy as the `projectionDef` instruction only
retrieves a list of selectors instead of also retrieving entries for
reserved projection slots which appear when using the default
selector multiple times (as seen above).
In order to fix this issue, the Ivy compiler now passes all
projection slots to the `projectionDef` instruction. Meaning that
there can be multiple projection slots with the same wildcard
selector. This allows multi-slot projection as seen in the
example above, and it also allows us to match the multi-slot node
projection order from View Engine (to avoid breaking changes).
It basically ensures that Ivy fully matches the View Engine behavior
except of a very small edge case that has already been discussed
in FW-886 (with the conclusion of working as intended).

fix(@schematics/angular): TypeScript related migrations should cater for BOM
In the CLI `UpdateRecorder` methods such as `insertLeft`, `remove` etc.. accepts positions which are not offset by a BOM. This is because when a file has a BOM a different recorder will be used https://github.com/angular/angular-cli/blob/master/packages/angular_devkit/schematics/src/tree/recorder.ts#L72 which caters for an addition offset/delta.
The main reason for this is that when a developer is writing a schematic they shouldn't need to compute the offset based if a file has a BOM or not and is handled out of the box.
Example
```ts
recorder.insertLeft(5, 'true');
```
However this is unfortunate in the case if a ts SourceFile is used and one uses `getWidth` and `getStart` method they will already be offset by 1, which at the end it results in a double offset and hence the problem.

Two issues with DebugNode/DebugElement in Ivy were causing problems in user
tests.
1. The DebugNodes returned by Ivy were not actually instances of DebugNode.
This was due to an issue with the Ivy switch logic in debug_node.ts.
The declaration of the exported DebugNode reference was set to
`DebugNode__PRE_R3__ as any`. The cast prevented the Ivy switch transform
from detecting this as a switchable declaration. The transform cannot handle
arbitrary syntax, and exports *must* be of the form "const x = y__PRE_R3__;"
or they will not work. The cast to any in this case was not needed, so this
commit removes it.
2. DebugNodes returned by Ivy multiple times for the same element were not
reference-identical. This was previously considered a minor breaking change
in Ivy, but testing has shown that users depend on referential equality of
DebugNodes. This commit caches a DebugNode on a DOM node when first creating
it, to allow returning the same instance in subsequent operations.

The R3TargetBinder "binds" an Angular template AST, computing semantic

One of the binding passes previously had a bug, where for the following
template:

<ng-template ngIf [ngIf]="foo" let-foo="ngIf">

contains the `<ng-template>` and the scope inside the template. The bug
arises because during the latter, `foo` is a variable defined by `let-foo`,

Plural ICU expressions depend on the locale (different languages have different plural forms). Until now the locale was hard coded as `en-US`.
For compatibility reasons, if you use ivy with AOT and bootstrap your app with `bootstrapModule` then the `LOCALE_ID` token will be set automatically for ivy, which is then used to get the correct plural form.
If you use JIT, you need to define the `LOCALE_ID` provider on the module that you bootstrap.
For `TestBed` you can use either `configureTestingModule` or `overrideProvider` to define that provider.
If you don't use the compat mode and start your app with `renderComponent` you need to call `ɵsetLocaleId` manually to define the `LOCALE_ID` before bootstrap. We expect this to change once we start adding the new i18n APIs, so don't rely on this function (there's a reason why it's a private export).

This is a new feature of the Ivy TestBed.
A common user pattern is to test one component with another. This is
commonly done by creating a `TestFixture` component which exercises the
main component under test.
This pattern is more difficult if the component under test is declared in an
NgModule but not exported. In this case, overriding the module is necessary.
In g3 (and View Engine), it's possible to use an NgSummary to override the
recompilation of a component, and depend on its AOT compiled factory. The
way this is implemented, however, specifying a summary for a module
effectively overrides much of the TestBed's other behavior. For example, the
following is legal:
```typescript
TestBed.configureTestingModule({
declarations: [FooCmp, TestFixture],
imports: [FooModule],
aotSummaries: [FooModuleNgSummary],
});
```
Here, `FooCmp` is declared in both the testing module and in the imported
`FooModule`. However, because the summary is provided, `FooCmp` is not
compiled within the context of the testing module, but _is_ made available
for `TestFixture` to use, even if it wasn't originally exported from
`FooModule`.
This pattern breaks in Ivy - because summaries are a no-op, this amounts
to a true double declaration of `FooCmp` which raises an error.
Fixing this in user code is possible, but is difficult to do in an
automated or backwards compatible way. An alternative solution is
implemented in this PR.
This PR attempts to capture the user intent of the following previously
unsupported configuration:
```typescript
TestBed.configureTestingModule({
declarations: [FooCmp, TestFixture],
imports: [FooModule],
});
```
Note that this is the same as the configuration above in Ivy, as the
`aotSummaries` value provided has no effect.
The user intent here is interpreted as follows:
1) `FooCmp` is a pre-existing component that's being used in the test
(via import of `FooModule`). It may or may not be exported by this
module.
2) `FooCmp` should be part of the testing module's scope. That is, it
should be visible to `TestFixture`. This is because it's listed in
`declarations`.
This feature effectively makes the `TestBed` testing module special. It's
able to declare components without compiling them, if they're already
compiled (or configured to be compiled) in the imports. And crucially, the
behavior matches the first example with the summary, making Ivy backwards
compatible with View Engine for tests that use summaries.

With Ivy, injecting a `ViewContainerRef` for a `<ng-container>` element
results in two comments generated in the DOM. One comment as host
element for the `ElementContainer` and one for the generated `LContainer`

This is problematic as developers expect the same anchor element for
the `LContainer` and the `ElementContainer` in order to be able to move
the host element of `<ng-container>` without leaving the actual
`LContainer` anchor element at the original location.
This worked differently in View Engine and various applications might
depend on the behavior where the `ViewContainerRef` shares the anchor
comment node with the host comment node of the `<ng-container>`. For
example `CdkTable` from `@angular/cdk` moves around the host element of
a `<ng-container>` and also expects embedded views to be inserted next
to the moved `<ng-container>` host element.

method. This commit removes `TestBed.deprecatedOverrideProvider`

Adds overloads to the `transform` methods of `SlicePipe`,
to have better types than `any` for `value` and `any` as a return.
With this commit, using `slice` in an `ngFor` still allow to type-check the content of the `ngFor`
with `fullTemplateTypeCheck` enabled in Ivy:
<div *ngFor="let user of users | slice:0:2">{{ user.typo }}</div>
|
`typo` does not exist on type `UserModel`
whereas it is currently not catched (as the return of `slice` is `any`) neither in VE nor in Ivy.
BREAKING CHANGE
`SlicePipe` now only accepts an array of values, a string, null or undefined.
This was already the case in practice, and it still throws at runtime if another type is given.
But it is now a compilation error to try to call it with an unsupported type.

Previously we defensively wrapped expressions in case they ran afoul of
precedence rules. For example, it would be easy to create the TS AST structure
Call(Ternary(a, b, c)), but might result in printed code of:
```
a ? b : c()
```
Whereas the actual structure we meant to generate is:
```
(a ? b : c)()
```
However the TypeScript renderer appears to be clever enough to provide
parenthesis as necessary.
This commit removes these defensive paraenthesis in the cases of binary
and ternary operations.

Previously, interpolations were generated into TCBs as a comma-separated
list of expressions, letting TypeScript infer the type of the expression
as the type of the last expression in the chain. This is undesirable, as
interpolations always result in a string type at runtime. Therefore,
type-checking of bindings such as `<img src="{{ link }}"/>` where `link`
is an object would incorrectly report a type-error.
This commit adjusts the emitted TCB code for interpolations, where a
chain of string concatenations is emitted, starting with the empty string.
This ensures that the inferred type of the interpolation is of type string.

This is the first refactor PR designed to change how styling bindings
(i.e. `[style]` and `[class]`) behave in Ivy. Instead of having a heavy

refactor aims to use a single context for each `tNode` element that is
examined and iterated over when styling values are to be applied to the
element.
This patch brings this new functionality to prop-based bindings such as
`[style.prop]` and `[class.name]`.

Previously, in order to assert that the promise was not resolved, an
error was thrown when the promise was resolved successfully. At the

the error thrown on resolving the promise, making the test pass, even if
the promise was not rejected.
This commit fixes it by ensuring that the error thrown on resolving the

A structural directive can specify a template guard for an input, such that
the type of that input's binding can be narrowed based on the guard's return
type. Previously, such template guards could only be methods, of which an
invocation would be inserted into the type-check block (TCB). For `NgIf`,
the template guard narrowed the type of its expression to be `NonNullable`
using the following declaration:
```typescript
export declare class NgIf {
static ngTemplateGuard_ngIf<E>(dir: NgIf, expr: E): expr is NonNullable<E>
}
```
This works fine for usages such as `*ngIf="person"` but starts to introduce
false-positives when e.g. an explicit non-null check like
`*ngIf="person !== null"` is used, as the method invocation in the TCB
would not have the desired effect of narrowing `person` to become
non-nullable:
```typescript
if (NgIf.ngTemplateGuard_ngIf(directive, ctx.person !== null)) {
// Usages of `ctx.person` within this block would
// not have been narrowed to be non-nullable.
}
```
This commit introduces a new strategy for template guards to allow for the
binding expression itself to be used as template guard in the TCB. Now,
the TCB generated for `*ngIf="person !== null"` would look as follows:
```typescript
if (ctx.person !== null) {
// This time `ctx.person` will successfully have
// been narrowed to be non-nullable.
}
```
This strategy can be activated by declaring the template guard as a
property declaration with `'binding'` as literal return type.
See #30235 for an example where this led to a false positive.

In View engine it is possible to instantiate a service that that has no
`@Injectable` decorator as long as it satisfies one of:
1) It has no dependencies and so a constructor with no parameters.
This is already supported in Ivy.
2) It has no constructor of its own and sub-classes a service which has
dependencies but has its own `@Injectable` decorator. This second
scenario was broken in Ivy.
In Ivy, previous to this commit, if a class to be instantiated did not have
its own `@Injectable` decorator and did not provide a constructor of
its own, then it would be created using `new` with no arguments -
i.e. falling back to the first scenario.

from the super-class to provide the `factory` for instantiating the
sub-class.

In some cases where multiple navigations happen to the same URL, the router will not process a given URL. In those cases, we fall into logic that resets state for the next navigation. One piece of this resetting is to set the `browserUrlTree` to the most recent `urlAfterRedirects`i.
However, there was bug in this logic because in some cases the `urlAfterRedirects` is a stale value. This happens any time a URL won't be processed, and the previous URL will also not be processed. This creates unpredictable behavior, not the least of which ends up being a broken `back` button.
This PR kicks off new navigations with the current value the router assumes is in the browser. All the logic around how to handle future navigations is based on this value compared to the current transition, so it's important to kick off all new navigations with the current value so in the edge case described above we don't end up with an old value being set into `browserUrlTree`.

To support skipping analysis of a file containing a component
we need to know that none of the declarations that might affect

files that are in each declared class's `CompilationScope` via
a new method, `recordNgModuleScopeDependencies()`, that is called
after all the handlers have been "resolved".
Further, if analysis is skipped for a declared class, then we need
to recover the analysis from the previous compilation run. To
support this, the `IncrementalState` class has been updated to
expose the `MetadataReader` and `MetadataRegistry` interfaces.

Packages that do not follow APF may have the declaration files in the same
directory as one source format, typically ES5. This is problematic for ngcc,
as it needs to create a TypeScript program with all JavaScript sources of
an entry-point, whereas TypeScript's module resolution mechanism would have
resolved an internal module import to the external facing .d.ts declaration
file, instead of the JavaScript source file. This behavior results in the
program to be analysed being incomplete.
This commit introduces a custom compiler host that recognizes the above
scenario and rewires the resolution of a .d.ts declaration file to its
JavaScript counterpart, if applicable.

Ivy uses R3Injector, but we are currently pulling in both the StaticInjector
(View Engine injector) and the R3Injector when running with Ivy. This commit
adds an ivy switch so calling Injector.create() pulls in the correct
implementation of the injector depending on whether you are using VE or Ivy.
This saves us about 3KB in the bundle.

Previously, we were supporting injection flags for provider deps, but only
if they fit the format `new Optional()`. This commit fixes resolution of
provider deps to also support `Optional` (without the new). This keeps us
backwards compatible with what View Engine supported.

Stores the views that are part of a container directly on the `LContainer`, rather than maintaining a dedicated sub-array.

Currently, we are not properly resolving forward refs when they appear
in deps for providers created with the useFactory strategy. This commit
wraps provider deps in the resolveForwardRef call so the tokens are
passed into the inject function as expected.

Fixes `HostBinding` and `HostListener` declarations not being inherited from base classes that don't have an Angular decorator.
This PR resolves FW-1275.

Currently the `static-query` migrations fails at the final step of
updating a query when the query already specifies options which
cannot be transformed easily. e.g. the options are computed through
a function call: `@ViewChild(..., getQueryOpts());` or `@ViewChild(..., myOptionsVar)`.
In these cases we technically could add additionally logic to update
the query options, but given that this is an edge-case and it's
potentially over-engineering the migration schematic, we just
always add a TODO for the timing and print out the determined
query timing in the console. The developer in that case just needs
to manually update the logic for the query options to contain the
printed query timing.

This PR adds the implementation for `definitionAndBoundSpan` because
it's now preferred over `definition`. vscode would send this new request
for `Go to definition`. As part of this PR the implementation for
`definition` is refactored and simplified. Goldens for both methods are
checked in.
