DTS bundling, will cause originally namespaced imports become namespace declarations within the same file. Example:
Before bundling
```ts
import * as i1 from './router';
export declare class RouterModule {
constructor(guard: any, router: Router);
static ɵmod: i0.ɵɵNgModuleDeclaration<RouterModule, [typeof i1.RouterOutlet...]>;
}
```
After bundling
```
declare namespace i1 {
export {
RouterOutletContract,
RouterOutlet
}
}
export declare class RouterModule {
constructor(guard: any, router: Router);
static ɵmod: i0.ɵɵNgModuleDeclaration<RouterModule, [typeof i1.RouterOutlet...]>;
}
```
And therefore this commit adds support for reflecting types that are defined in such namespace declarations.

Updates the api-extractor dependencies of the repository, and within
the `@angular/bazel` package so that TypeScript 4.3 is supported when
a flattened typings file is generated. Without this update, the api
extractor could fail if a referenced tsconfig use a TS 4.3-only option such as
`noImplicitOverride`.
Note: This could also be considered a `feat:` for `@angular/bazel`,
but this package is not part of the public API anyway and we'd want
that change to land in the patch branches too (to keep the goldens
in sync between release branches as much as possible)

Historically, our Language Service was built with the potential to be a
drop-in replacement for the TypeScript Language Service with the added
benefit of being able to provide Angular-specific information as well.
While our VSCode extension does not use the Language Service in this
way, it appears that other community-contributed plugins do. We don't
really officially support this use-case but there's not real reason for
us to override the TypeScript Language Service's
implementation in the VE Angular Language Service so that it returns
`undefined`. As with other non-implemented methods, we can just allow
this to be deferred to TSLS.

When `TestBed.compileComponents` is called under ViewEngine, we kick off a compilation and return a promise that resolves once the compilation is done. In most cases the consumer doesn't _have_ to await the returned promise, unless their components have external resources.
The problem is that the test could be over by the time the promise has resolved, in which case we still cache the factory of the test module. This becomes a problem if another compilation is triggered right afterwards, because it'll see that we still have a `_moduleFactory` and it won't recreate the factory.
These changes resolve the issue by saving a reference to the module type that is being compiled and checking against it when the promise resolves.
Note that while this problem was discovered while trying to roll out the new test module teardown behavior in the Components repo (https://github.com/angular/components/pull/23070), it has been there for a long time. The new test behavior made it more apparent.

Previously, the SW was only able to clean up caches for app-versions
found in the `Driver`'s `versions` map. If (for some reason) the
`Driver` failed to load a valid stored state (including app-versions)
and ended up with an [empty `versions` map][1], any obsolete versions
would remain in the cache storage. This case was rare but possible.
This commit makes the cache clean-up logic more robust by ensuring that
all app-version caches are removed unless they are currently used by the
SW to serve active clients (with the exception of the latest
app-version, which is always retained).

This commit simplifies/systemizes accessing the `CacheStorage` through a
wrapper, with the following benefits:
- Ensuring a consistent cache name prefix is used for all caches
(without having to repeat the prefix in different places).
- Allowing referring to caches using their name without the common
cache name prefix.
- Exposing the cache name on cache instances, which for example makes it
easier to delete caches without having to keep track of the name used
to create them.

This commit improves the cache names generated by the ServiceWorker by
making them shorter and non-repetitive. In particular, the following
changes are made:
- Data-group cache names no longer include the `dynamic` infix, since it
does not add any value.
Before: `ngsw:<...>:data:dynamic:<...>`
After: `ngsw:<...>:data:<...>`
- `CacheDatabase` table names no longer include the `ngsw:<path>` prefix
twice.
Before: `ngsw:<path>:db:ngsw:<path>:<...>`
After: `ngsw:<path>:db:<...>`
NOTE 1:
This change will result in different cache names being generated for the
same app-versions with the new SericeWorker script. This means that some
of the previously cached data will need to be re-downloaded (because the
ServiceWorker will not be able to re-use the old caches), but that
should be transparent for the end user.
While possible, adding logic to allow the ServiceWorker to retrieve data
from the old caches is not worth the extra complecity and maintenance
cost.
NOTE 2:
Generating different cache names for some of the caches means that the
ServiceWorker will not be able to clean-up some of the old caches. This
will be taken care of in a subsequent commit that will rework the
clean-up logic to be more robust (covering changes such as this one and
other edgecases).

`CacheDatabase` uses the un-prefixed table names to interact with
database tables. However, the `list()` method returns the raw, prefixed
table names (which are not useful, since they cannot be used to
open/delete a table).
This commit fixes this by removing the prefix from the cache names
returned by the `list()` method.

This method is currently not used anywhere, so this change does not

Previously the lexer would break out of consuming a text token if it contains
a `<` character. Then if the next characters did not indicate an HTML syntax
item, such as a tag or comment, then it would start a new text token. These
consecutive text tokens are then merged into each other in a post tokenization
step.
In the commit before this, interpolation no longer leaks across text tokens.
The approach given above to handling `<` characters that appear in text is
no longer adequate. This change ensures that the lexer only breaks out of
a text token if the next characters indicate a valid HTML tag, comment,
CDATA etc.
PR Close#42605
When consuming a text token, the lexer tracks whether it is reading characters
from inside an interpolation so that it can identify invalid ICU expressions.
Inside an interpolation there will be no ICU expression so it is safe to
have unmatched `{` characters, but outside an interpolation this is an error.
Previously, if an interpolation was started, by an opening marker (e.g. `{{`)
in a text token but the text came to an end before the closing marker (e.g. `}}`)
then the lexer was not clearing its internal state that tracked that it was
inside an interpolation. When the next text token was being consumed,
the lexer, incorrectly thought it was already within an interpolation.
This resulted in invalid ICU expression errors not being reported.
For example, in the following snippet, the first text block has a prematurely
ended interpolation, and the second text block contains an invalid `{` character.
```
<div>{{</div>
<div>{</div>
```
Previously, the lexer would not have identified this as an error. Now there
will be an EOF error that looks like:
```
TS-995002: Unexpected character "EOF"
(Do you have an unescaped "{" in your template? Use "{{ '{' }}") to escape it.)
```
PR Close#42605
The ServiceWorker assigns an app-version to a each client to ensure that
all subsequent requests for a client are served using the same
app-version. The assignment is done based on the client ID.
Previously, the ServiceWorker would only try to read the client's ID off
of the `FetchEvent`'s `clientId` property. However, for navigation
requests the new client's ID will be set on [resultingClientId][1],
while `clientId` will either be empty or hold the ID of the client where
the request initiated from. See also related discussions in
w3c/ServiceWorker#870 and w3c/ServiceWorker#1266.
In theory, this could lead to the navigation request (i.e. `index.html`)
being served from a different app-version than the subsequent
sub-resource requests (i.e. assets). In practice, the likelihood of this
happening is probably very low though, since it would require the latest
app-version to be updated between the initial navigation request and the
first sub-resource request, which should happen very shortly after the
navigation request.
This commit ensures that the correct client ID is determined even for
navigation requests by also taking the `resultingClientId` property into
account.

Previously, the template type checker would only opt-in to inline type
constructors if it could import all type references from absolute module
specifiers. This limitation was put into place in an abundance of
caution as there was a safe, but less performant, fallback available.
The language service is not capable of using this fallback, which now
means that the limitation of absolute module specifiers limits the
language service's ability to use accurate types for component/directive
classes that have generic type parameters.
This commit loosens the restriction such that type references are now
eligible for emit as long as they are exported.
PR Close#42492
When a component/directive has a generic type parameter, the template
type checker attempts to translate the type parameter such that the
type parameters can be replicated in the type constructor that is
emitted into the typecheck file.
Type parameters with a default clause would incorrectly be emitted into
the typecheck file using the original `ts.TypeNode` for the default
clause, such that `ts.TypeReferenceNode`s within the default clause
would likely be invalid (i.e. referencing a type for which no import is
present in the typecheck file). This did not result in user-facing
type-check errors as errors reported in type constructors are not
translated into template positions Regardless, this commit ensures that
`ts.TypeReferenceNode`s within defaults are properly translated into the
typecheck file.
PR Close#42492
The template type checker is capable of recreating generic type bounds
in a different context, rewriting type references along the way (if
possible). This was previously done using a visitor that only supported
a limited set of types, resulting in the inability to emit all sorts of
types (even if they don't contain type references at all).
The inability to emit generic type bounds was not critical when the type
parameter emitting logic was introduced, as the compiler also has a
fallback strategy of creating inline type constructors. However, this
fallback is not available to the language service, resulting in
inaccurate types when components/directives use a complex generic type.
To mitigate this problem, the specialized visitor has been replaced with
a generalized TypeScript transform, where only type references get
special treatment. This allows for more complex types to be emitted,
such as union and intersection types, object literal types and tuple
types.

This is something I ran into while working on a fix for the `TestBed` module teardown behavior for #18831. In the `RouterInitializer.appInitializer` we have a callback to the `LOCATION_INITIALIZED` which has to do some DI lookups. The problem is that if the module is destroyed before the location promise resolves, the `Injector.get` calls will fail. This is unlikely to happen in a real app, but it'll show up in unit tests once the test module teardown behavior is fixed.
PR Close#42560
We currently have two long-standing issues related to how `TestBed` tests are torn down:
1. The dynamically-created test module isn't going to be destroyed, preventing the `ngOnDestroy` hooks on providers from running and keeping the component `style` nodes in the DOM.
2. The test root elements aren't going to be removed from the DOM. Instead, they will be removed whenever another test component is created.
By themselves, these issues are easy to resolve, but given how long they've been around, there are a lot of unit tests out there that depend on the broken behavior.
These changes address the issues by introducing APIs that allow users to opt into the correct test teardown behavior either at the application level via `TestBed.initTestEnvironment` or the test suite level via `TestBed.configureTestingModule`.
At the moment, the new teardown behavior is opt-in, but the idea is that we'll eventually make it opt-out before removing the configuration altogether.
