Currently unless a listener inside of an embedded view tries to reference something from the parent view, or if the reference is a local ref, we don't generate the view restoration instructions and we allow for the value to be picked up from the context object in the function parameters. The problem is that the listener is only run during creation mode and the context object may have been swapped out afterwards.
These changes fix the issue by always generating the view restoration instructions for listeners inside templates.
Fixes#42698.

In #42492 the template type checker became capable of replicating a
wider range of generic type parameters for use in template type-check
files. Any literal types within a type parameter would however emit
invalid code, as TypeScript was emitting the literals using the text as
extracted from the template type-check file instead of the original
source file where the type node was taken from.
This commit works around the issue by cloning any literal types and
marking them as synthetic, signalling to TypeScript that the literal
text has to be extracted from the node itself instead from the source
file.
This commit also excludes `import()` type nodes from being supported,
as their module specifier may potentially need to be rewritten.

Updates the Bazel NodeJS rules to v4.0.0-beta.0. This is necessary
so that the Angular components repo can update, and it's generally
good to stay as up-to-date as possible with the Bazel rules as it's
easy to fall behind, and updating early allows us to discover issues
affecting our tooling earlier (where they are easier to address due to
e.g. potential breaking change policy).

This commit applies changes to `@angular/bazel` which are necessary
to support the Bazel NodeJS rules v4.0.0. The Bazel NodeJS rules
no longer support the `_tslibrary` option for the `LinkablePackageInfo`
provider and therefore we need to stop using it. Due to this removal,
we also need to add two new attributes called `package_name` and
`package_path` so that the API of `ng_module` matches `ts_library`.
Note: This is denoted as `refactor` as we currently are not able to
merge feature commits into patch branches, but we want the tooling
to not diverge significantly between the patch and next branch. It is
planned to update the merge tooling to allow for such changes to land.

Skydoc is no longer used as `@angular/bazel` is no longer a

in the repo where Sass is not really needed and has just been

in preparation for Rules NodeJS v4.x where the Sass rules currently
still use an older version of `@bazel/worker` that is incompatible.

Rollup just prints a warning if an import cannot be resolved and ends up
being treated as an external dependency. This in combination with the
`silent = True` attribute for `rollup_bundle` means that bundles might
end up being extremely small without people noticing that it misses
actual imports.
To improve this situation, the warning is replaced by an error if
an import cannot be resolved.
This unveiles an issue with the `ng_rollup_bundle` macro from
dev-infra where imports in View Engine were not resolved but ended
up being treated as external. This did not prevent benchmarks using
this macro from working because the ConcatJS devserver had builtin
resolution for workspace manifest paths. Though given the new check
for no unresolved imports, this will now cause errors within Rollup, and
we need to fix the resolution. We can fix the issue by temporarily
enabling workspace linking. This does not have any performance
downsides.
To enable workspace linking (which we might need more often in the
future given the linker taking over patched module resolution), we
had to rename the `angular` dependency to a more specific one so
that the Angular linker could link into `node_modules/angular`.

When another navigation is triggered during an in-process navigation and
the `canceledNavigationResolution` is `'computed'`, we should not
attempt to restore the browser history using `history.go`. Doing that
would trigger a third navigation through the router which would conflict
with the new navigation that we were trying to process. Instead, we
treat this as a redirect and skip the history restoration attempt. This
acts similarly to returning `UrlTree` from a guard.

Previously, the ServiceWorker assumed that a client found in
`clientVersionMap` would exist (i.e. it could be retrieved via
`clients.get()`). However, if a browser tab had been closed, the
corresponding client (while present in `clientVersionMap`, which is only
updated on ServiceWorker initialization) would not be retrievable via
`clients.get()`.
This commit fixes it by checking whether the client exists before trying
to notify it about an unrecoverable state.

The ServiceWorker needs to keep track of some metadata for unhashed
asset resources to know if/when they might need to be revalidated. This
applies to resources that do not exist on the filesystem at build-time
(and thus cannot be hashed), such as fonts or images loaded from
external sources. For hashed resources, this metadata is irrelevant,
because the hash is enough to verify that the content hasn't changed and
no revalidation is necessary.
Previously, the ServiceWorker would store such metadata for hashed
resources as well, even though it would never be used (thus taking up
space unnecessarily).
This commit fixes it by not storing metadata for hashed resources, i.e.
those that are included in an asset-group's `hashes` array.

Source files that contain directives or components that need an inline
type constructor or inline template type-check block would always be
considered as affected in incremental rebuilds. The inline operations
cause the source file to be updated in the TypeScript program that is
created for template type-checking, which becomes the reuse program
in a subsequent incremental rebuild.
In an incremental rebuild, the source files from the new user program
are compared to those from the reuse program. The updated source files
are not the same as the original source file from the user program, so
the incremental engine would mark the file which needed inline
operations as affected. This prevents incremental reuse for these files,
causing sub-optimal rebuild performance.
This commit attaches the original source file for source files that have
been updated with inline operations, such that the incremental engine
is able to compare source files using the original source file.

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.

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`,

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.
PR Close#42622
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
