There is an inconsistency in overrideProvider behaviour. Testing documentation says
(https://angular.io/guide/testing-components-basics#createcomponent) that all override...
methods throw error if TestBed is already instantiated. However overrideProvider doesn't throw any error, but (same as
other override... methods) doesn't replace providers if TestBed is instantiated. Add TestBed instantiation check to
overrideProvider method to make it consistent.
BREAKING CHANGE:
If you call `TestBed.overrideProvider` after TestBed initialization, provider overrides are not applied. This
behavior is consistent with other override methods (such as `TestBed.overrideDirective`, etc) but they
throw an error to indicate that, when the check was missing in the `TestBed.overrideProvider` function.
Now calling `TestBed.overrideProvider` after TestBed initialization also triggers an
error, thus there is a chance that some tests (where `TestBed.overrideProvider` is
called after TestBed initialization) will start to fail and require updates to move `TestBed.overrideProvider` calls
before TestBed initialization is completed.

The `RefreshTransplantedView` flag is used to indicate that the view or one of its children
is transplanted and dirty, so it should still be refreshed as part of change detection.
This flag is set on the transplanted view itself as well setting a
counter on as its parents.
When a transplanted view is detached and still has this flag, it means
it got detached before it was refreshed. This can happen for "backwards
references" or transplanted views that are inserted at a location that
was already checked. In this case, we should decrement the parent

Fix a bug in the HTML sanitizer where an unclosed iframe tag would
result in an escaped closing body tag as the output:
_sanitizeHtml(document, '<iframe>') => '</body>'
This closing body tag comes from the DOMParserHelper where the HTML to be
sanitized is wrapped with surrounding body tags. When an opening iframe
tag is parsed by DOMParser, which DOMParserHelper uses, everything up
until its matching closing tag is consumed as a text node. In the above
example this includes the appended closing body tag.
By removing the explicit closing body tag from the DOMParserHelper and
relying on the body tag being closed implicitly at the end, the above
example is sanitized as expected:

Similarly to the change we landed in the `@angular/core` reflection
capabilities, we need to make sure that ngcc can detect pass-through
delegate constructors for classes using downleveled ES2015 output.
More details can be found in the preceding commit, and in the issue
outlining the problem: #38453.
Fixes#38453.
PR Close#38463
In the Angular Package Format, we always shipped UMD bundles and previously even ES5 module output.
With V10, we removed the ES5 module output but kept the UMD ES5 output.
For this, we were able to remove our second TypeScript transpilation. Instead we started only
building ES2015 output and then downleveled it to ES5 UMD for the NPM packages. This worked
as expected but unveiled an issue in the `@angular/core` reflection capabilities.
In JIT mode, Angular determines constructor parameters (for DI) using the `ReflectionCapabilities`. The
reflection capabilities basically read runtime metadata of classes to determine the DI parameters. Such
metadata can be either stored in static class properties like `ctorParameters` or within TypeScript's `design:params`.
If Angular comes across a class that does not have any parameter metadata, it tries to detect if the
given class is actually delegating to an inherited class. It does this naively in JIT by checking if the
stringified class (function in ES5) matches a certain pattern. e.g.
```js
function MatTable() {
var _this = _super.apply(this, arguments) || this;
```
These patterns are reluctant to changes of the class output. If a class is not recognized properly, the
DI parameters will be assumed empty and the class is **incorrectly** constructed without arguments.
This actually happened as part of v10 now. Since we downlevel ES2015 to ES5 (instead of previously
compiling sources directly to ES5), the class output changed slightly so that Angular no longer detects
it. e.g.
```js
var _this = _super.apply(this, __spread(arguments)) || this;
```
This happens because the ES2015 output will receive an auto-generated constructor if the class
defines class properties. This constructor is then already containing an explicit `super` call.
```js
export class MatTable extends CdkTable {
constructor() {
super(...arguments);
this.disabled = true;
}
}
```
If we then downlevel this file to ES5 with `--downlevelIteration`, TypeScript adjusts the `super` call so that
the spread operator is no longer used (not supported in ES5). The resulting super call is different to the
super call that would have been emitted if we would directly transpile to ES5. Ultimately, Angular no
longer detects such classes as having an delegate constructor -> and DI breaks.
We fix this by expanding the rather naive RegExp patterns used for the reflection capabilities
so that downleveled pass-through/delegate constructors are properly detected. There is a risk
of a false-positive as we cannot detect whether `__spread` is actually the TypeScript spread
helper, but given the reflection patterns already make lots of assumptions (e.g. that `super` is
actually the superclass, we should be fine making this assumption too. The false-positive would
not result in a broken app, but rather in unnecessary providers being injected (as a noop).

When using the safe navigation operator in a binding expression, a temporary
variable may be used for storing the result of a side-effectful call.
For example, the following template uses a pipe and a safe property access:
```html
<app-person-view [enabled]="enabled" [firstName]="(person$ | async)?.name"></app-person-view>
```
The result of the pipe evaluation is stored in a temporary to be able to check
whether it is present. The temporary variable needs to be declared in a separate
statement and this would also cause the full expression itself to be pulled out
into a separate statement. This would compile into the following
pseudo-code instructions:
```js
var temp = null;
var firstName = (temp = pipe('async', ctx.person$)) == null ? null : temp.name;
property('enabled', ctx.enabled)('firstName', firstName);
```
Notice that the pipe evaluation happens before evaluating the `enabled` binding,
such that the runtime's internal binding index would correspond with `enabled`,
not `firstName`. This introduces a problem when the pipe uses `WrappedValue` to
force a change to be detected, as the runtime would then mark the binding slot
corresponding with `enabled` as dirty, instead of `firstName`. This results
in the `enabled` binding to be updated, triggering setters and affecting how
`OnChanges` is called.
In the pseudo-code above, the intermediate `firstName` variable is not strictly
necessary---it only improved readability a bit---and emitting it inline with
the binding itself avoids the out-of-order execution of the pipe:
```js
var temp = null;
property('enabled', ctx.enabled)
('firstName', (temp = pipe('async', ctx.person$)) == null ? null : temp.name);
```
This commit introduces a new `BindingForm` that results in the above code to be
generated and adds compiler and acceptance tests to verify the proper behavior.

In JIT compiled apps, component definitions are compiled upon first
access. For a component class `A` that extends component class `B`, the
`B` component is also compiled when the `InheritDefinitionFeature` runs
during the compilation of `A` before it has finalized. A problem arises
when the compilation of `B` would flush the NgModule scoping queue,
where the NgModule declaring `A` is still pending. The scope information
would be applied to the definition of `A`, but its compilation is still
in progress so requesting the component definition would compile `A`
again from scratch. This "inner compilation" is correctly assigned the
NgModule scope, but once the "outer compilation" of `A` finishes it
would overwrite the inner compilation's definition, losing the NgModule
scope information.
In summary, flushing the NgModule scope queue could trigger a reentrant
compilation, where JIT compilation is non-reentrant. To avoid the
reentrant compilation, a compilation depth counter is introduced to
avoid flushing the NgModule scope during nested compilations.

This allows Closure compiler to tree shake unused constructor calls to `NgModuleFactory`, which is otherwise considered
side-effectful. The Angular compiler generates factory objects which are exported but typically not used, as they are
only needed for compatibility with View Engine. This results in top-level constructor calls, such as:
```typescript
export const FooNgFactory = new NgModuleFactory(Foo);
```
`NgModuleFactory` has a side-effecting constructor, so this statement cannot be tree shaken, even if `FooNgFactory` is
never imported. The `NgModuleFactory` continues to reference its associated `NgModule` and prevents the module and all
its unused dependencies from being tree shaken. This effectively prevents all components from being tree shaken, making
Closure builds significantly larger than they should be.
The fix here is to wrap `NgModuleFactory` constructor with `noSideEffects(() => /* ... */)`, which tricks the Closure
compiler into assuming that the invoked function has no side effects. This allows it to tree-shake unused
`NgModuleFactory()` constructors when they aren't imported. Since the factory can be removed, the module can also be
removed (if nothing else references it), thus tree shaking unused components as expected.

Previously the instructions were included in the golden files to monitor the frequency and rate of

considered for becoming a public API and deployed to npm via generated code).
This experiment has confirmed that the instruction API is not stable enough to be used as public

The are three instructions that are still being included: `ɵɵdefineInjectable`, `ɵɵinject`, and

These instructions are already generated by the VE compiler to support tree-shakable providers, and
code depending on these instructions is already deployed to npm. For this reason we need to treat
them as public api.
This change also reduces the code review overhead, because changes to public api golden files now

Currently we read lifecycle hooks eagerly during `ɵɵdefineComponent`.
The result is that it is not possible to do any sort of meta-programing
such as mixins or adding lifecycle hooks using custom decorators since
any such code executes after `ɵɵdefineComponent` has extracted the
lifecycle hooks from the prototype. Additionally the behavior is
inconsistent between AOT and JIT mode. In JIT mode overriding lifecycle
hooks is possible because the whole `ɵɵdefineComponent` is placed in
getter which is executed lazily. This is because JIT mode must compile a
template which can be specified as `templateURL` and those we are
waiting for its resolution.
- `+` `ɵɵdefineComponent` becomes smaller as it no longer needs to copy
lifecycle hooks from prototype to `ComponentDef`
- `-` `ɵɵNgOnChangesFeature` feature is now always included with the
codebase as it is no longer tree shakable.
Previously we have read lifecycle hooks from prototype in the
`ɵɵdefineComponent` so that lifecycle hook access would be monomorphic.
This decision was made before we had `T*` data structures. By not
reading the lifecycle hooks we are moving the megamorhic read form
`ɵɵdefineComponent` to instructions. However, the reads happen on
`firstTemplatePass` only and are subsequently cached in the `T*` data
structures. The result is that the overall performance should be same
(or slightly better as the intermediate `ComponentDef` has been
removed.)

One of the ivy acceptance tests currently fails in IE10. This
is because we recently added a new test that asserts that injecting
`ViewRef` results in a `NullInjectorError`.
Due to limitations in TypeScript and in polyfills for `setPrototypeOf`,
the error cannot be thrown as `ViewRef` is always considered injectable.
In reality, `ViewRef` should not be injectable, as explicitly noted
in c00f4ab2ae.
There seems no way to simulate the proper prototype chain in such
browsers that do not natively support `__proto__`, so TypeScript
and `core-js` polyfills simply break the prototype chain and
assign inherited properties directly on `ViewRef`. i.e. so that
`ViewRef.__NG_ELEMENT_ID__` exists and DI picks it up.
There is a way for TypeScript to theoretically generate proper
prototype chain in ES5 output, but they intend to only bother
about the proper prototype chain in ES6 where `setPrototypeOf`

As of v10, the `undecorated-classes-with-decorated-fields` migration
generally deals with undecorated classes using Angular features. We
intended to run this migation as part of v10 again as undecorated
classes with Angular features are no longer supported in planned v11.
The migration currently behaves incorrectly in some cases where an
`@Injectable` or `@Pipe` decorated classes uses the `ngOnDestroy`
lifecycle hook. We incorrectly add a TODO for those classes. This
commit fixes that.
Additionally, this change makes the migration more robust to
not migrate a class if it inherits from a component, pipe
injectable or non-abstract directive. We previously did not
need this as the undecorated-classes-with-di migration ran
before, but this is no longer the case.
Last, this commit fixes an issue where multiple TODO's could be
added. This happens when multiple Angular CLI build targets have
an overlap in source files. Multiple programs then capture the
same source file, causing the migration to detect an undecorated
class multiple times (i.e. adding a TODO twice).

Interestingly enough, our rollup bundle optimization pipeline
did not work properly before 1b827b058e5060963590628d4735e6ac83c6dfdd.
Unused declarations were not elided because build optimizer did not
consider the Angular packages as side-effect free. Build optimizer has
a hard-coded list of Angular packages that are considered side-effect
free. Though this one did not match in the old version of the rollup
bundle rule, as internal sources were resolved through their resolved
bazel-out paths. Hence build optimizer could not detect the known
Angular framework packages. Now though, since we leverage the
Bazel-idiomatic `@bazel/rollup` implementation, sources are resolved
through linked `node_modules`, and build optimizer is able to properly
detect files as side-effect free.

Refactors the `ng_rollup_bundle` rule to a macro that relies on
the `@bazel/rollup` package. This means that the rule no longer
deals with custom ESM5 flavour output, but rather only builds
prodmode ES2015 output. This matches the common build output
in Angular projects, and optimizations done in CLI where
ES2015 is the default optimization input.
The motiviation for this change is:
* Not duplicating rollup Bazel rules. Instead leveraging the official
rollup rule.
* Not dealing with a third TS output flavor in Bazel.The ESM5 flavour has the
potential of slowing down local development (as it requires compilation replaying)
* Updating the rule to be aligned with current CLI optimizations.
This also _fixes_ a bug that surfaced in the old rollup bundle rule.
Code that is unused, is not removed properly. The new rule fixes this by
setting the `toplevel` flag. This instructs terser to remove unused
definitions at top-level. This matches the optimization applied in CLI
projects. Notably the CLI doesn't need this flag, as code is always
wrapped by Webpack. Hence, the unused code eliding runs by default.

This is a known issue of zone.js,

Since in this case, we use native `setTimeout` which is not a ZoneTask,
so zone.js consider the button click handler as the top Task then drain the
microTaskQueue after the click at once, which is not correct(too early).
This case was an edge case and not reported by the users, until we have the
new option ngZoneEventCoalescing, since the event coalescing will happen
in native requestAnimationFrame, so it will not be a ZoneTask, and zone.js will
consider any Task happen in the change detection stage as the top task, and if
there are any microTasks(such as Promise.then) happen in the process, it may be
drained earlier than it should be, so to prevent this situation, we need to schedule
a fake event task and run the change detection check in this fake event task,
so the Task happen in the change detection stage will not be
considered as top ZoneTask.

Currently Angular internally already handles `InjectionToken` as
predicates for queries. This commit exposes this as public API as
developers already relied on this functionality but currently use
workarounds to satisfy the type constraints (e.g. `as any`).
We intend to make this public as it's low-effort to support, and
it's a significant key part for the use of light-weight tokens as
described in the upcoming guide: https://github.com/angular/angular/pull/36144.
In concrete, applications might use injection tokens over classes
for both optional DI and queries, because otherwise such references
cause classes to be always retained. This was also an issue in View
Engine, but now with Ivy, this pattern became worse, as factories are
directly attached to retained classes (ultimately ending up in the
production bundle, while being unused).

In v7 of Angular we removed `tsickle` from the default `ngc` pipeline.
This had the negative potential of breaking ES2015 output and SSR due
to a limitation in TypeScript.
TypeScript by default preserves type information for decorated constructor
parameters when `emitDecoratorMetadata` is enabled. For example,
consider this snippet below:
```
@Directive()
export class MyDirective {
constructor(button: MyButton) {}
}
export class MyButton {}
```
TypeScript would generate metadata for the `MyDirective` class it has
a decorator applied. This metadata would be needed in JIT mode, or
for libraries that provide `MyDirective` through NPM. The metadata would
look as followed:
```
let MyDirective = class MyDir {}
MyDirective = __decorate([
Directive(),
__metadata("design:paramtypes", [MyButton]),
], MyDirective);
let MyButton = class MyButton {}
```
Notice that TypeScript generated calls to `__decorate` and
`__metadata`. These calls are needed so that the Angular compiler
is able to determine whether `MyDirective` is actually an directive,
and what types are needed for dependency injection.
The limitation surfaces in this concrete example because `MyButton`
is declared after the `__metadata(..)` call, while `__metadata`
actually directly references `MyButton`. This is illegal though because
`MyButton` has not been declared at this point. This is due to the
so-called temporal dead zone in JavaScript. Errors like followed will
be reported at runtime when such file/code evaluates:
```
Uncaught ReferenceError: Cannot access 'MyButton' before initialization
```
As noted, this is a TypeScript limitation because ideally TypeScript
shouldn't evaluate `__metadata`/reference `MyButton` immediately.
Instead, it should defer the reference until `MyButton` is actually
declared. This limitation will not be fixed by the TypeScript team
though because it's a limitation as per current design and they will
only revisit this once the tc39 decorator proposal is finalized
(currently stage-2 at time of writing).
Given this wontfix on the TypeScript side, and our heavy reliance on
this metadata in libraries (and for JIT mode), we intend to fix this
from within the Angular compiler by downleveling decorators to static
properties that don't need to evaluate directly. For example:
```
MyDirective.ctorParameters = () => [MyButton];
```
With this snippet above, `MyButton` is not referenced directly. Only
lazily when the Angular runtime needs it. This mitigates the temporal
dead zone issue caused by a limitation in TypeScript's decorator
metadata output. See: https://github.com/microsoft/TypeScript/issues/27519.
In the past (as noted; before version 7), the Angular compiler by
default used tsickle that already performed this transformation. We
moved the transformation to the CLI for JIT and `ng-packager`, but now
we realize that we can move this all to a single place in the compiler
so that standalone ngc consumers can benefit too, and that we can
disable tsickle in our Bazel `ngc-wrapped` pipeline (that currently
still relies on tsickle to perform this decorator processing).
This transformation also has another positive side-effect of making
Angular application/library code more compatible with server-side
rendering. In principle, TypeScript would also preserve type information
for decorated class members (similar to how it did that for constructor
parameters) at runtime. This becomes an issue when your application
relies on native DOM globals for decorated class member types. e.g.
```
@Input() panelElement: HTMLElement;
```
Your application code would then reference `HTMLElement` directly
whenever the source file is loaded in NodeJS for SSR. `HTMLElement`
does not exist on the server though, so that will become an invalid
reference. One could work around this by providing global mocks for
these DOM symbols, but that doesn't match up with other places where
dependency injection is used for mocking DOM/browser specific symbols.
More context in this issue: #30586. The TL;DR here is that the Angular
compiler does not care about types for these class members, so it won't
ever reference `HTMLElement` at runtime.

If we detect that an injectable class is inheriting from another injectable, we generate code that looks something like this:
```
const baseFactory = ɵɵgetInheritedFactory(Child);
@Injectable()
class Parent {}
@Injectable()
class Child extends Parent {
static ɵfac = (t) => baseFactory(t || Child)
}
```
This usually works fine, because the `ɵɵgetInheritedFactory` resolves to the factory of `Parent`, but the logic can break down if the `Child` class has a custom decorator. Custom decorators can return a new class that extends the original once, which means that the `ɵɵgetInheritedFactory` call will now resolve to the factory of the `Child`, causing an infinite loop.
These changes fix the issue by changing the inherited factory resolution logic so that it walks up the prototype chain class-by-class, while skipping classes that have the same factory as the class that was passed in.

version we publish on npm
which is primarily optimized for Webpack/Rollup + Terser build pipeline.
As a temporary workaround you might consider using your current build
pipeline with Closure flag
`--compilation_level=SIMPLE`. This flag will ensure that your build
pipeline produces buildable and
runnable artifacts, at the cost of increased payload size due to
advanced optimizations being disabled.

Enables the `ng update` migrations for v10. Status for individual
migrations:
**undecorated-classes-with-di**.
This migration dealt exlusively with inherited constructors and
cases where a derived component was undecorated. In those cases,
the migration added `@Directive()` or copied the inherited decorator
to the derived class.
We don't need to run this migration again because ngtsc throws if
constructor is inherited from an undecorated class. Also ngtsc will
throw if a NgModule references an undecorated class in the declarations.
***undecorated-classes-with-decorated-fields***
This migration exclusively deals with undecorated classes that use
Angular features but are not decorated. Angular features include
the use of lifecycle hooks or class fields with Angular decorators,
such as `@Input()`.
We want to re-run this migration in v10 as we will disable the
compatibility code in ngtsc that detects such undecorated classes
as `@Directive`.
**module-with-providers**:
This migration adds an explicit generic type to `ModuleWithProviders`.
As of v10, the generic type is required, so we need to re-run the
migration again.
**renderer-to-renderer2**:
We don't need to re-run that migration again as the
renderer has been already removed in v9.
**missing-injectable**:
This migration is exclusively concerned with undecorated
providers referenced in an `NgModule`. We should re-run
that migration again as we don't have proper backsliding
prevention for this yet. We can consider adding an error
in ngtsc for v10, or v11. In either way, we should re-run
the migration.
**dynamic-queries**:
We ran this one in v9 to reduce code complexity in projects. Instead
of explicitly passing `static: false`, not passing any object literal
has the same semantics. We don't need to re-run the migration again
since there is no good way to prevent backsliding and we cannot always
run this migration for future versions (as some apps might actually
intentionally use the explicit `static: false` option).

the type checker to resolve base classes of individual classes.
It could happen that resolved base classes have no value declaration.
e.g. if they are declared through an interface in the default types.
Currently the migration will throw in such situations because it assumes
that `ts.Symbol#valueDeclaration` is always present. This is not the
case, but we don't get good type-checking here due to a bug in the
TypeScript types. See:
https://github.com/microsoft/TypeScript/issues/24706.

Currently destroy hooks are stored in memory as `[1, hook, 5, hook]` where
the numbers represent the index at which to find the context and `hook` is
the function to be invoked. This breaks down for `multi` providers,
because the value at the index will be an array of providers, resulting in
the hook being invoked with an array of all the multi provider values,
rather than the provider that was destroyed. In ViewEngine `ngOnDestroy`
wasn't being called for `multi` providers at all.
These changes fix the issue by changing the structure of the destroy hooks to `[1, hook, 5, [0, hook, 3, hook]]` where the indexes inside the inner array point to the provider inside of the multi provider array. Note that this is slightly different from the original design which called for the structure to be `[1, hook, 5, [hook, hook]`, because in the process of implementing it, I realized that we wouldn't get passing the correct context if only some of the `multi` providers have `ngOnDestroy` and others don't.
I've run the newly-added `view_destroy_hooks` benchmark against these changes and compared it to master. The difference seems to be insignificant (between 1% and 2% slower).

In rare cases a project with configured `rootDirs` that has imports to
non-existent identifiers could fail in the migration.
This happens because based on the application code, the migration could
end up trying to resolve the `ts.Symbol` of such non-existent
identifiers. This isn't a problem usually, but due to a upstream bug
in the TypeScript compiler, a runtime error is thrown.
This is because TypeScript is unable to compute a relative path from the
originating source file to the imported source file which _should_
provide the non-existent identifier. An issue for this has been reported
upstream: https://github.com/microsoft/TypeScript/issues/37731. The
issue only surfaces since our migrations don't provide an absolute base
path that is used for resolving the root directories.
To fix this, we ensure that we never use relative paths when parsing
tsconfig files. More details can be found in the TS issue.

In version 10, undecorated base classes that use Angular features need
to be decorated explicitly with `@Directive()`. Additionally, derived
classes of abstract directives need to be decorated.
The migration already handles this for undecorated classes that are
not explicitly decorated, but since in V9, abstract directives can be
used, we also need to handle this for explicitly decorated abstract
directives. e.g.
```
@Directive()
export class Base {...}
// needs to be decorated by migration when updating from v9 to v10
export class Wrapped extends Base {}
@Component(...)

We don't have an integration test for the `undecorated-classes-with-decorated-fields

it to the `ng update` integration test.
PR Close#35339
The `undecorated-classes-with-decorated-fields` migration has been
introduced with 904a2018e0, but misses
logic for decorating derived classes of undecorated classes which use
Angular features. Example scenario:
```ts
export abstract class MyBaseClass {
@Input() someInput = true;
}
export abstract class BaseClassTwo extends MyBaseClass {}
@Component(...)
export class MyButton extends BaseClassTwo {}
```
Both abstract classes would need to be migrated. Previously, the migration
only added `@Directive()` to `MyBaseClass`, but with this change, it
also decorates `BaseClassTwo`.
This is necessary because the Angular Compiler requires `BaseClassTwo` to
have a directive definition when it flattens the directive metadata for
`MyButton` in order to perform type checking. Technically, not decorating
`BaseClassTwo` does not break at runtime.
We basically want to enforce consistent use of `@Directive` to simplify the
mental model. [See the migration guide](https://angular.io/guide/migration-undecorated-classes#migrating-classes-that-use-field-decorators).

This commit augments the `FactoryDef` declaration of Angular decorated
classes to contain information about the parameter decorators used in
the constructor. If no constructor is present, or none of the parameters
have any Angular decorators, then this will be represented using the
`null` type. Otherwise, a tuple type is used where the entry at index `i`
corresponds with parameter `i`. Each tuple entry can be one of two types:
1. If the associated parameter does not have any Angular decorators,
the tuple entry will be the `null` type.
2. Otherwise, a type literal is used that may declare at least one of
the following properties:
- "attribute": if `@Attribute` is present. The injected attribute's
name is used as string literal type, or the `unknown` type if the
attribute name is not a string literal.
- "self": if `@Self` is present, always of type `true`.
- "skipSelf": if `@SkipSelf` is present, always of type `true`.
- "host": if `@Host` is present, always of type `true`.
- "optional": if `@Optional` is present, always of type `true`.
A property is only present if the corresponding decorator is used.
Note that the `@Inject` decorator is currently not included, as it's
non-trivial to properly convert the token's value expression to a
type that is valid in a declaration file.
Additionally, the `ComponentDefWithMeta` declaration that is created for
Angular components has been extended to include all selectors on
`ng-content` elements within the component's template.
This additional metadata is useful for tooling such as the Angular
Language Service, as it provides the ability to offer suggestions for
directives/components defined in libraries. At the moment, such
tooling extracts the necessary information from the _metadata.json_
manifest file as generated by ngc, however this metadata representation
is being replaced by the information emitted into the declaration files.

When using `platformBrowserDynamic().bootstrapModule()`, it is possible
to set `defaultEncapsulation` and `preserveWhitespaces` as default
configuration to influence how components are compiled. When compiling
components in JIT with Ivy, these options were not taken into account.
This commit publishes the options to be globally available, so that the
lazy compilation of JIT components has access to the configured
bootstrap options. Note that this approach does not allow changing the
options once they have been set, as Ivy's compilation model does not
allow for multiple compilations to exist at the same time.
For applications that bootstrap multiple modules, it is now required
to provide the exact same bootstrap options. An error is logged if
incompatible bootstrap options are provided, in which case the updated
options will be ignored.

This commit performs a few updates to internal functions that would be required in upcoming changes to support synthetic host bindings in Directives.
* the `elementPropertyInternal` function was refactored to accept renderer as an argument (prior to that, there was a function that loads the renderer in some specific way for animation bindings)
* `elementPropertyInternal`, `elementAttributeInternal` and `listenerInternal` functions were updated to have a fixed set of arguments (for better performance)
* `elementPropertyInternal` and `elementAttributeInternal` functions were updated to take `tNode` as an argument instead of passing node index (that was used to retrieve `tNode` internally), in some cases we already have `tNode` available or we can retrieve it from the state
The refactoring was triggered by the need to pass different renderers to the `elementPropertyInternal` to support synthetic host bindings in Directives (see this comment for additional context: https://github.com/angular/angular/pull/35568/files#r388034584).

Prior to this commit, i18n runtime logic relied on the assumption that provided translation is syntactically correct, specifically around ICU syntax. However provided translations might contain some errors that lead to parsing failure. Specifically when translation contains curly braces, runtime i18n logic tries to parse them as an ICU expression and fails. This commit validates ICU parsing result (making sure it was parsed correctly) and throws an error if parsing error happens. The error that is thrown also contains translated message text for easier debugging.
Note: the check and the error message introduced in this PR is a safeguard against the problem that led to unhandled i18n runtime logic crash. So the framework behavior remains the same, we just improve the error message and it should be safe to merge to the patch branch.

This commit adds support in the Angular monorepo and in the Angular
compiler(s) for TypeScript 3.8. All packages can now compile with
TS 3.8.
For most of the repo, only a handful few typings adjustments were needed:
* TS 3.8 has a new `CustomElementConstructor` DOM type, which enforces a
zero-argument constructor. The `NgElementConstructor` type previously
declared a required `injector` argument despite the fact that its
implementation allowed `injector` to be optional. The interface type was
updated to reflect the optionality of the argument.
* Certain error messages were changed, and expectations in tests were
updated as a result.
* tsserver (part of language server) now returns performance information in
responses, so test expectations were changed to only assert on the actual
body content of responses.
For compiler-cli and schematics (which use the TypeScript AST) a major
breaking change was the introduction of the export form:
```typescript
export * as foo from 'bar';
```
This is a `ts.NamespaceExport`, and the `exportClause` of a
`ts.ExportDeclaration` can now take this type as well as `ts.NamedExports`.
This broke a lot of places where `exportClause` was assumed to be
`ts.NamedExports`.
For the most part these breakages were in cases where it is not necessary
to handle the new `ts.NamedExports` anyway. ngtsc's design uses the
`ts.TypeChecker` APIs to understand syntax and so automatically supports the
new form of exports.
The View Engine compiler on the other hand extracts TS structures into
metadata.json files, and that format was not designed for namespaced
exports. As a result it will take a nontrivial amount of work if we want to
support such exports in View Engine. For now, these new exports are not
accounted for in metadata.json, and so using them in "folded" Angular
expressions will result in errors (probably claiming that the referenced
exported namespace doesn't exist).
Care was taken to only use TS APIs which are present in 3.7/3.6, as Angular
needs to remain compatible with these for the time being.

Prior to this commit, while calculating the scope for a module, Ivy compiler processed `declarations` field first and `imports` after that. That results in a couple issues:
* for Pipes with the same `name` and present in `declarations` and in an imported module, Pipe from imported module was selected. In View Engine the logic is opposite: Pipes from `declarations` field receive higher priority.
* for Directives with the same selector and present in `declarations` and in an imported module, we first invoked the logic of a Directive from `declarations` field and after that - imported Directive logic. In View Engine, it was the opposite and the logic of a Directive from the `declarations` field was invoked last.
In order to align Ivy and View Engine behavior, this commit updates the logic in which we populate module scope: we first process all imports and after that handle `declarations` field. As a result, in Ivy both use-cases listed above work similar to View Engine.

The options for `flatModuleId` and `flatModuleOutFile` had been removed in the CLI
from generated libraries with 718ee15b9a.
This has been done because `ng-packagr` (which is used to build the
libraries) automatically set these options in-memory when it compiles the library.
No migration has been created for this because there was no actual need to get rid of
this. Keeping the options in the library `tsconfig` does not cause any problems unless
the `tsconfig` is used outside of `ng-packagr`. This was not anticipated, but is now
commonly done in `ng update` migrations.
The `ng update` migrations try to create an instance of the `AngularCompilerProgram` by
simply parsing the `tsconfig`. The migrations make the valid assumption that `tsconfig` files
are not incomplete/invalid. They _definitely_ are in the file system though. It just works for
libraries because `ng-packagr` in-memory completes the invalid `tsconfig` files, so that they
can be passed to the `@angular/compiler-cli`.
We can't have this logic in the `ng update` migrations because it's
out-of-scope for individual migrations to distinguish between libraries
and applications. Also it would be out-of-scope to parse the
`ng-packagr` configuration and handle the tsconfig in-memory completion.
As a workaround though, we can remove the flat-module bundle options
in-memory when creating the compiler program. This is acceptable since
we don't emit the program and the flat module bundles are not needed.

Currently we resolve the `NgModuleRef.componentFactoryResolver` by going through the injector, but the problem is that `ComponentFactoryResolver` has a dependency on `NgModuleRef`, which means that if the module that's attached to the ref tries to inject `ComponentFactoryResolver` in its constructor, we'll create a circular dependency which throws at runtime.
These changes resolve the issue by creating the `ComponentFactoryResolver` manually ahead of time without going through the injector. We can do this safely, because the only dependency for the resolver is the current module ref which is providing it.

This means that the key for `{foo: pureFunction0(...)}` and `{foo: null}` are the same.

for function invocations, we generate a variable called `<unknown>` which
shouldn't be able to collide with anything.
