When ngtsc comes across a source file during partial evaluation, it
would determine all exported symbols from that module and evaluate their
values greedily. This greedy evaluation strategy introduces unnecessary
work and can fall into infinite recursion when the evaluation result of
an exported expression would circularly depend on the source file. This
would primarily occur in CommonJS code, where the `exports` variable can
be used to refer to an exported variable. This variable would be
resolved to the source file itself, thereby greedily evaluating all
exported symbols and thus ending up evaluating the `exports` variable
again. This variable would be resolved to the source file itself,
thereby greedily evaluating all exported symbols and thus ending u
evaluating the `exports` variable again. This variable would be
resolved to the source file itself, thereby greedily evaluating all
exported symbols and thus ending up evaluating the `exports` variable
again. This variable would be resolved to the source file itself,
thereby greedily evaluating all exported symbols and thus ending up
evaluating the `exports` variable again. This went on for some time
until all stack frames were exhausted.
This commit introduces a `ResolvedModule` that delays the evaluation of
its exports until they are actually requested. This avoids the circular
dependency when evaluating `exports`, thereby fixing the issue.

The template type checker generates code to check directive inputs and

identifier in TypeScript. Prior to this change, such names would be
emitted into the generated code as is, resulting in invalid code and

This commit fixes the bug by representing the potentially invalid names

NgModule compilation in JIT mode (that is also used in TestBed) caches module scopes on NgModule defs (using `transitiveCompileScopes` field). Module overrides (defined via TestBed.overrideModule) may invalidate this data by adding/removing items in `declarations` list.

This commit transforms the setClassMetadata calls generated by ngtsc from:
```typescript
/*@__PURE__*/ setClassMetadata(...);
```
to:
```typescript
/*@__PURE__*/ (function() {
setClassMetadata(...);
})();
```
Without the IIFE, terser won't remove these function calls because the
function calls have arguments that themselves are function calls or other
impure expressions. In order to make the whole block be DCE-ed by terser,
we wrap it into IIFE and mark the IIFE as pure.
It should be noted that this change doesn't have any impact on CLI* with
build-optimizer, which removes the whole setClassMetadata block within
the webpack loader, so terser or webpack itself don't get to see it at
all. This is done to prevent cross-chunk retention issues caused by
webpack's internal module registry.
* actually we do expect a short-term size regression while
https://github.com/angular/angular-cli/pull/16228
is merged and released in the next rc of the CLI. But long term this
change does nothing to CLI + build-optimizer configuration and is done
primarly to correct the seemingly correct but non-function PURE annotation
that builds not using build-optimizer could rely on.

NgModules in Ivy have a definition which contains various different bits
of metadata about the module. In particular, this metadata falls into two
categories:
* metadata required to use the module at runtime (for bootstrapping, etc)
in AOT-only applications.
* metadata required to depend on the module from a JIT-compiled app.
The latter metadata consists of the module's declarations, imports, and
exports. To support JIT usage, this metadata must be included in the
generated code, especially if that code is shipped to NPM. However, because
this metadata preserves the entire NgModule graph (references to all
directives and components in the app), it needs to be removed during
optimization for AOT-only builds.
Previously, this was done with a clever design:
1. The extra metadata was added by a function called `setNgModuleScope`.
A call to this function was generated after each NgModule.
2. This function call was marked as "pure" with a comment and used
`noSideEffects` internally, which causes optimizers to remove it.
The effect was that in dev mode or test mode (which use JIT), no optimizer
runs and the full NgModule metadata was available at runtime. But in
production (presumably AOT) builds, the optimizer runs and removes the JIT-
specific metadata.
However, there are cases where apps that want to use JIT in production, and
still make an optimized build. In this case, the JIT-specific metadata would
be erroneously removed. This commit solves that problem by adding an
`ngJitMode` global variable which guards all `setNgModuleScope` calls. An
optimizer can be configured to statically define this global to be `false`
for AOT-only builds, causing the extra metadata to be stripped.
A configuration for Terser used by the CLI is provided in `tooling.ts` which
sets `ngJitMode` to `false` when building AOT apps.

The Ivy template type-checker is capable of inferring the type of a
structural directive (such as NgForOf<T>). Previously, this was done with
fullTemplateTypeCheck: true, even if strictTemplates was false. View Engine
previously did not do this inference, and so this causes breakages if the
type of the template context is not what the user expected.
In particular, consider the template:
```html
<div *ngFor="let user of users as all">
{{user.index}} out of {{all.length}}
</div>
```
As long as `users` is an array, this seems reasonable, because it appears
that `all` is an alias for the `users` array. However, this is misleading.
In reality, `NgForOf` is rendered with a template context that contains
both a `$implicit` value (for the loop variable `user`) as well as a
`ngForOf` value, which is the actual value assigned to `all`. The type of
`NgForOf`'s template context is `NgForContext<T>`, which declares `ngForOf`'s
type to be `NgIterable<T>`, which does not have a `length` property (due to
its incorporation of the `Iterable` type).
This commit stops the template type-checker from inferring template context
types unless strictTemplates is set (and strictInputTypes is not disabled).

Previously, the ngtsc compiler attempted to reuse analysis work from the
previous program during an incremental build. To do this, it had to prove
that the work was safe to reuse - that no changes made to the new program
would invalidate the previous analysis.
The implementation of this had a significant design flaw: if the previous
program had errors, the previous analysis would be missing significant
information, and the dependency graph extracted from it would not be
sufficient to determine which files should be re-analyzed to fill in the
gaps. This often meant that the build output after an error was resolved
would be wholly incorrect.
This commit switches ngtsc to take a simpler approach to incremental
rebuilds. Instead of attempting to reuse prior analysis work, the entire
program is re-analyzed with each compilation. This is actually not as
expensive as one might imagine - analysis is a fairly small part of overall
compilation time.
Based on the dependency graph extracted during this analysis, the compiler
then can make accurate decisions on whether to emit specific files. A new
suite of tests is added to validate behavior in the presence of source code
level errors.
This new approach is dramatically simpler than the previous algorithm, and
should always produce correct results for a semantically correct program.s

Originally, QueryList implemented Iterable and provided a Symbol.iterator
on its prototype. This caused issues with tree-shaking, so QueryList was
refactored and the Symbol.iterator added in its constructor instead. As
part of this change, QueryList no longer implemented Iterable directly.
Unfortunately, this meant that QueryList was no longer assignable to
Iterable or, consequently, NgIterable. NgIterable is used for NgFor's input,
so this meant that QueryList was not usable (in a type sense) for NgFor
iteration. View Engine's template type checking would not catch this, but
Ivy's did.
As a fix, this commit adds the declaration (but not the implementation) of
the Symbol.iterator function back to QueryList. This has no runtime effect,
so it doesn't affect tree-shaking of QueryList, but it ensures that
QueryList is assignable to NgIterable and thus usable with NgFor.

Previously, the compiler assumed that all TS files logically within a
project existed under one or more "root directories". If the TS compiler
option `rootDir` or `rootDirs` was set, they would dictate the root
directories in use, otherwise the current directory was used.
Unfortunately this assumption was unfounded - it's common for projects
without explicit `rootDirs` to import from files outside the current
working directory. In such cases the `LogicalProjectStrategy` would attempt
to generate imports into those files, and fail. This would lead to no
`ReferenceEmitStrategy` being able to generate an import, and end in a
compiler assertion failure.
This commit introduces a new strategy to use when there are no `rootDirs`
explicitly present, the `RelativePathStrategy`. It uses simpler, filesystem-

suffixed to become unique. In ES5-like bundles this results in the outer

As an example, the following code would fail to have a `Directive`
decorator as ngcc would search for `__decorate` calls that refer to
`AliasedDirective$1` by name, whereas the `__decorate` call actually
uses the `AliasedDirective` name.
```javascript
var AliasedDirective$1 = /** @class */ (function () {
function AliasedDirective() {}
AliasedDirective = tslib_1.__decorate([

During incremental compilations, ngtsc needs to know which metadata
from a previous compilation can be reused, versus which metadata has to
be recomputed as some dependency was updated. Changes to
directives/components should cause the NgModule in which they are
declared to be recompiled, as the NgModule's compilation is dependent
on its directives/components.
When a dependent source file of a directive/component is updated,
however, a more subtle dependency should also cause to NgModule's source
file to be invalidated. During the reconciliation of state from a
previous compilation into the new program, the component's source file
is invalidated because one of its dependency has changed, ergo the
NgModule needs to be invalidated as well. Up until now, this implicit
dependency was not imposed on the NgModule. Additionally, any change to
a dependent file may influence the module scope to change, so all

When the Angular compiler is operated through the ngc binary in watch
mode, changing a template in an external file would not cause the
component to be recompiled if Ivy is enabled.
There was a problem with how a cached compiler host was present that was
unaware of the changed resources, therefore failing to trigger a
recompilation of a component whenever its template changes. This commit
fixes the issue by ensuring that information about modified resources is
correctly available to the cached compiler host.

The `ngInjectableDef` property was renamed to `ɵprov`, but core must
still support both because there are published libraries that use the
older term.
We are only interested in such properties that are defined directly on
the type being injected, not on base classes. So there is a check that
the defintion is specifically for the given type.
Previously if you tried to inject a class that had `ngInjectableDef` but
also inherited `ɵprov` then the check would fail on the `ɵprov` property
and never even try the `ngInjectableDef` property resulting in a failed
injection.
This commit fixes this by attempting to find each of the properties
independently.

Most of the use of `document` in the framework is within
the DI so they just inject the `DOCUMENT` token and are done.
Ivy is special because it does not rely upon the DI and must
get hold of the document some other way. There are a limited
number of places relevant to ivy that currently consume a global
document object.
The solution is modelled on the `LOCALE_ID` approach, which has
`getLocaleId()` and `setLocaleId()` top-level functions for ivy (see
`core/src/render3/i18n.ts`). In the rest of Angular (i.e. using DI) the
`LOCALE_ID` token has a provider that also calls setLocaleId() to
ensure that ivy has the same value.
This commit defines `getDocument()` and `setDocument() `top-level
functions for ivy. Wherever ivy needs the global `document`, it calls
`getDocument()` instead. Each of the platforms (e.g. Browser, Server,
WebWorker) have providers for `DOCUMENT`. In each of those providers
they also call `setDocument()` accordingly.
Fixes#33651
PR Close#33712
It looks like there was a typo when it originally was
written. As it works right now, the `beforeEach` and
`afterEach` cancel each other out. But then
`ensureDocument()` is called anyway in the `withBody()`
function.
With this change there is no need to call `ensureDocument() in the
`withBody() function.

Previously the renderers were fixed so that they inserted extra
"adjacent" statements after the last static property of classes.
In order to help the build-optimizer (in Angular CLI) to be able to
tree-shake classes effectively, these statements should also appear
after any helper calls, such as `__decorate()`.
This commit moves the computation of this positioning into the
`NgccReflectionHost` via the `getEndOfClass()` method, which
returns the last statement that is related to the class.

While overriding providers in Ivy TestBed (via TestBed.overrideProvider call), the old providers were retained in the list, since the override takes precedence. However, presence of providers in the list might have side-effect: if a provider has the `ngOnDestroy` lifecycle hook, this hook will be registered and invoked later (when component is destroyed). This commit updates TestBed logic to clear provider list by removing the ones which have overrides.

When debugging `LView`s it is easy to get lost since all of them have
the same name. This change does three things:
1. It makes `TView` have an explicit type:
- `Host`: for the top level `TView` for bootstrap
- `Component`: for the `TView` which represents components template
- `Embedded`: for the `TView` which represents an embedded template
2. It changes the name of `LView` to `LHostView`, `LComponentView`, and
`LEmbeddedView` depending on the `TView` type.
3. For `LComponentView` and `LEmbeddedView` we also append the name of
of the `context` constructor. The result is that we have `LView`s which
are name as: `LComponentView_MyComponent` and `LEmbeddedView_NgIfContext`.
The above changes will make it easier to understand the structure of the
application when debugging.
NOTE: All of these are behind `ngDevMode` and will get removed in

To support compile time localization, we need to be
able to provide the locales via a well known global property.
This commit changes `getLocaleData()` so that it will attempt
to read the local from the global `ng.common.locales` if the
locale has not already been registered via `registerLocaleData()`.
PR Close#33523
To limit the exposure of the private `LOCALE_DATA` from outside
`@angular/core` this commit exposes private functions in the core
to hide the internal structures better.
* The `registerLocaleData()` implementation has moved from
`@angular/common` to `@angular/core`. A stub that delegates to
core has been left in common for backward compatibility.
* A new `ɵunregisterLocaleData()` function has been provided,
which is particularly useful in tests to clear out registered locales
to prevent subsequent tests from being affected.
* A private export of `ɵregisterLocaleData()` has been removed
from `@angular/common`. This was not being used and is accessible

In order to support adding locales during compile-time
inlining of translations (i.e. after the TS build has completed),
we need to be able to attach the locale to the global scope.
This commit modifies CLDR extraction to emit additional "global"
locale files that appear in the `@angular/common/locales/global` folder.
These files are of the form:
```
(function() {
const root = typeof globalThis !== 'undefined' && globalThis ||
typeof global !== 'undefined' && global || typeof window !== 'undefined' && window;
root.ng = root.ng || {};
root.ng.common = root.ng.common || {};
root.ng.common.locale = root.ng.common.locale || {};
const u = undefined;
function plural(n) {
if (n === 1) return 1;
return 5;
}
root.ng.common.locale['xx-yy'] = [...];
})();
```
The IIFE will ensure that `ng.common.locale` exists and attach the
given locale (and its "extras") to it using it "normalized" locale
name.
* "extras": in the UMD module locale files the "extra" locale data,
currently the day period rules, and extended day period data, are
stored in separate files under the "common/locales/extra" folder.
* "normalized": Angular references locales using a normalized form,
which is lower case with `_` replaced by `-`. For example:
`en_UK` => `en-uk`.

When compiling an Angular decorator (e.g. Directive), @angular/compiler
generates an 'expression' to be added as a static definition field
on the class, a 'type' which will be added for that field to the .d.ts
file, and a statement adjacent to the class that calls `setClassMetadata()`.
Previously, the same WrappedNodeExpr of the class' ts.Identifier was used
within each of this situations.
In the ngtsc case, this is proper. In the ngcc case, if the class being
compiled is within an ES5 IIFE, the outer name of the class may have
changed. Thus, the class has both an inner and outer name. The outer name
should continue to be used elsewhere in the compiler and in 'type'.
The 'expression' will live within the IIFE, the `internalType` should be used.
The adjacent statement will also live within the IIFE, the `adjacentType` should be used.
This commit introduces `ReflectionHost.getInternalNameOfClass()` and
`ReflectionHost.getAdjacentNameOfClass()`, which the compiler can use to
query for the correct name to use.

During static evaluation of expressions within ngtsc, it may occur that
certain expressions or just parts thereof cannot be statically
interpreted for some reason. The static interpreter keeps track of the
failure reason and the code path that was evaluated by means of
`DynamicValue`, which will allow descriptive errors. In some situations
however, the static interpreter would throw an exception instead,
resulting in a crash of the compilation. Not only does this cause
non-descriptive errors, more importantly does it prevent the evaluated
result from being partial, i.e. parts of the result can be dynamic if
their value does not have to be statically available to the compiler.
This commit refactors the static interpreter to never throw errors for
certain expressions that it cannot evaluate.

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.

CLI, built-in schematics are being run to update user code from
deprecated patterns to the new way of working. For libraries that have

present, potentially resulting in incorrect behavior.

ngcc would produce errors when a base class could not be determined

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

of template type checking. However, now that more advanced type checking
is being done, new errors may surface that were previously not reported,

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.

Previously, we had tested that expressions parsed in a Render3 AST
had correctly-defined absolute spans (spans relative to the entire
template, not the local expression). Sometimes we use Template ASTs
rather than Render3 ASTs, and it's desirable to test for correct
expression spans in the template parser as well.
Adding these tests resolved one bug, similar to the one fixed in

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
structural changes of the template parser testing layout. In particular,
the following is done:
1. Move `createMeta*`-like functions from `template_parser_spec.ts` to
be exported from a new test utility file.
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};
}
```

Here, the method call should be targeting the `$implicit` variable on
the template context, not the component class. This commit corrects the
behavior by first resolving methods in the template before falling back
on the component class.

In View Engine, with fullTemplateTypeCheck mode disabled, the type of any
inferred based on the entity being referenced. This is a bug, since the
goal with fullTemplateTypeCheck: false is for Ivy and VE to be aligned in
terms of type inference.
This commit adds a 'checkTypeOfReference' flag in the TypeCheckingConfig
to control this inference, and sets it to false when fullTemplateTypeCheck
is disabled.

Libraries can expose directive/component base classes that will be
used by consumer applications. Using such a base class from another
compilation unit works fine with "ngtsc", but when using "ngc", the
compiler will thrown an error saying that the base class is not
part of a NgModule. e.g.
```
Cannot determine the module for class X in Y! Add X to the NgModule to fix it.
```
This seems to be because the logic for distinguishing directives from
abstract directives is scoped to the current compilation unit within
ngc. This causes abstract directives from other compilation units to
be considered as actual directives (causing the exception).

Prior to this commit, we always invoked second i18n pass (in case whitespace removal is on, which is a default), even if a given template doesn't contain i18n information. Now we store a flag (that indicates presence of i18n information in a template) during first i18n pass and use it to check whether second pass is needed.
PR Close#33284
When computing i18n messages for templates there are two passes.
This is because messages must be computed before any whitespace
is removed. Then on a second pass, the messages must be recreated
but reusing the message ids from the first pass.
Previously ICUs were losing their legacy ids that had been computed
via the first pass. This commit fixes that by keeping track of the
message from the first pass (`previousMessage`) for ICU placeholder
nodes.

This commit adapts the private NgModule re-export system (using aliasing) to
ngcc. Not all ngcc compilations are compatible with these re-exports, as
they assume a 1:1 correspondence between .js and .d.ts files. The primary
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).
PR Close#33237
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
flags are not set explicitly.

Resubmit #31168 now that google3 tests can pass. This requires http://cl/272696717 to be patched.
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.

Until now, the template type checker has not checked any of the event
bindings that could be present on an element, for example
```
<my-cmp
(changed)="handleChange($event)"
(click)="handleClick($event)"></my-cmp>
```
has two event bindings: the `change` event corresponding with an
`@Output()` on the `my-cmp` component and the `click` DOM event.
This commit adds functionality to the template type checker in order to
type check both kind of event bindings. This means that the correctness
of the bindings expressions, as well as the type of the `$event`
variable will now be taken into account during template type checking.

In ES5 modules, the class declarations consist of an IIFE with inner

Before this commit, if an identifier referred to an alias of the inner
declaration, then `getDeclarationOfIdentifier()` was failing to find
the outer declaration - instead returning the inner declaration.
Now the identifier is correctly resolved up to the outer declaration
as expected.
