Kristiyan Kostadinov 404c8d0d88 fix(compiler): incorrect context object being referenced from listener instructions inside embedded views (#42755)
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.

JoostK 4c482bf3f1 fix(compiler-cli): properly emit literal types when recreating type parameters in a different file (#42761)
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.

Paul Gschwendtner 762e057e85 build: update to rules_nodejs v4.0.0-beta.0 (#42760)
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).

Paul Gschwendtner 9da68a77e6 refactor(bazel): compatibility with `rules_nodejs` v4.0.0 (#42760)
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.

Paul Gschwendtner b1fa1bf0d5 fix(dev-infra): `ng_rollup_bundle` rule should error if import cannot be resolved (#42760)
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`.

Andrew Scott 3791ae0c95 refactor(router): Adjust behavior for computed navigation restoration (#42751)
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.

George Kalpakas cb2ca9a66e fix(service-worker): correctly handle unrecoverable state when a client no longer exists (#42736)
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()`.

George Kalpakas f592a12005 fix(service-worker): avoid storing redundant metadata for hashed assets (#42606)
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.

JoostK 30c82cd177 fix(compiler-cli): inline type checking instructions no longer prevent incremental reuse (#42759)
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.

Kristiyan Kostadinov 0f23f7343e fix(core): error in TestBed if module is reset mid-compilation in ViewEngine (#42669)
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.

George Kalpakas 73b0275dc2 fix(service-worker): improve ServiceWorker cache names (#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).

Pete Bacon Darwin 9de65dbdce fix(compiler): should not break a text token on a non-valid start tag (#42605)
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.

Pete Bacon Darwin c873440ad2 fix(compiler): do not allow unterminated interpolation to leak into later tokens (#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.)

George Kalpakas 9498da1038 fix(service-worker): correctly determine client ID on navigation requests (#42607)
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.

JoostK a9dd7e21a2 refactor(compiler-cli): enable relative imports in the type parameter emitter (#42492)
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.

JoostK 729eea5716 fix(compiler-cli): transform type references in generic type parameter default (#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.

JoostK 16aaa23d4e refactor(compiler-cli): use TypeScript transform to emit type parameters (#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.

Kristiyan Kostadinov 873229f24b feat(core): add opt-in test module teardown configuration (#42566)
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.

Andrew Scott 228beeabd1 fix(language-service): Use last child end span for parent without close tag (#42554)
Unclosed element tags are not assigned an `endSourceSpan` by the parser.
As a result, the visitor which determines the target node at a position
for the language service was unable to determine that a given position
was inside an unclosed parent. This happens because we update the
`endSourceSpan` of template/element nodes to be the end tag (and there
is not one for unclosed tags). Consequently, the visitor then cannot
match a position to any child node location.

This change updates the visitor logic to check if there are any
`children` of a template/element node and updates the end span to be the
end span of the last child. This allows our `isWithin` logic to identify
that a child position is within the unclosed parent.

Paul Gschwendtner 044e0229bd build: generate alias locale data for closure locale (#42230)
Within Google, closure compiler is used for dealing with translations.
We generate a closure-compatible locale file that allows for
registration within Angular, so that Closure i18n works well together
with Angular applications. Closure compiler does not limit its
locales to BCP47-canonical locale identifiers. This commit updates
the generation logic so that we also support deprecated (but aliased)
locale identifiers, or other aliases which are likely used within
Closure. We use CLDR's alias supplemental data for this. It instructs
us to alias `iw` to `he` for example. `iw` is still supported in Closure.

Note that we do not manually extract all locales supported in Closure;
instead we only support the CLDR canonical locales (as done before) +
common aliases that CLDR provides data for. We are not aware of other
locale aliases within Closure that wouldn't be part of the CLDR aliases.
If there would be, then Angular/Closure would fail accordingly.

Paul Gschwendtner 8f24d71142 build: simplify generation of closure locale file (#42230)
In the past, the closure file has been generated so that all individual
locale files were imported individually. This resulted in a huge
slow-down in g3 due to the large amount of imports.

With 90bd984ff7 this changed so that we
inline the locale data for the g3 closure locale file. Also the file
only contained data for locales being supported by Closure. For this a
list of locales has been extracted from Closure Compiler, as well as a
list of locale aliases.

This logic is prone to CLDR version updates, and also broke as part of
the Gulp -> Bazel migration where this logic has been slightly modified
but caused issues in G3. e.g. a locale `zh-Hant` was requested in g3,
but the locale data had the name of the alias locale that provided the
data at index zero (which represents the locale name). Note that the
locale names at index zero always could differentiate from the requested
`goog.LOCALE` due to the aliasing logic. This just didn't come up before.

We simplify this logic by generating a `goog.LOCALE` case for all
locales CLDR provides data for. We don't need to bother about aliasing
because with the refactorings to the CLDR generation tool, all locales
are built (which also captures the aliases), and we can generate the locale
file on the fly (which has not been done before).

Paul Gschwendtner 1eaeb23c75 build: convert CLDR locale extraction from Gulp to Bazel tool (#42230)
Converts the CLDR locale extraction script to a Bazel tool.
This allows us to generate locale files within Bazel, so that
locales don't need to live as sources within the repo. Also
it allows us to get rid of the legacy Gulp tooling.

The migration of the Gulp script to a Bazel tool involved the
following things:

  1. Basic conversion of the `extract.js` script to TypeScript.
     This mostly was about adding explicit types. e.g. adding `locale:
     string` or `localeData: CldrStatic`.

  2. Split-up into separate files. Instead of keeping the large
     `extract.js` file, the tool has been split into separate files.
     The logic remains the same, just that code is more readable and
     maintainable.

  3. Introduction of a new `index.ts` file that is the entry-point
     for the Bazel tool. Previously the Gulp tool just generated
     all locale files, the default locale and base currency files
     at once. The new entry-point accepts a mode to be passed as
     first process argument. based on that argument, either locales
     are generated into a specified directory, or the default locale,
     base currencies or closure file is generated.

     This allows us to generate files with a Bazel genrule where
     we simply run the tool and specify the outputs. Note: It's
     necessary to have multiple modes because files live in separate
     locations. e.g. the default locale in `@angular/core`, but the
     rest in `@angular/common`.

  4. Removal of the `cldr-data-downloader` and custom CLDR resolution
     logic. Within Bazel we cannot run a downloader using network.

     We switch this to something more Bazel idiomatic with better
     caching. For this a new repository rule is introduced that
     downloads the CLDR JSON repository and extracts it. Within
     that rule we determine the supported locales so that they
     can be used to pre-declare outputs (for the locales) within
     Bazel analysis phase. This allows us to add the generated locale
     files to a `ts_library` (which we want to have for better testing,
     and consistent JS transpilation).

     Note that the removal of `cldr-data-downloader` also requires us to
     add logic for detecting locales without data. The CLDR data
     downloader overwrote the `availableLocales.json` file with a file
     that only lists locales that CLDR provides data for. We use the
     official `availableLocales` file CLDR provides, but filter out
     locales for which no data is available. This is needed until we
     update to CLDR 39 where data is available for all such locales
     listed in `availableLocales.json`.

In watch builds, the compiler attempts to reuse as much information from

Previously the autoRegisterModuleById registration was marked with noSideEffects wrapper to ensure that we don't end up retaining all NgModules.

However the return value was not referenced by anything, so closure compiler removed it because it determined that this code has no side effects and is not referenced by anyone.

This issue affects apps that use Closure Compiler and also rely on https://angular.io/api/core/getModuleFactory to retrieve factories by ID. This combination is used heavily in google3, especially in Pantheon.

Andrew Scott 536c3738ba docs: clarify onSameUrlNavigation behavior (#42275)
`onSameUrlNavigation` only affects whether the Angular Router
processes the URL and runs it through the navigation pipeline,
retriggering redirects, guards, and resolvers. The name `reload` is a
little confusing because it does _not_ reload the component. Developers
_also_ need to implement a custom `RouteReuseStrategy` to trigger a
component reload on same URL navigation.

Fixes #21115

Dylan Hunn 34ce635e3a feat(forms): undo revert and add ng-submitted class to forms that have been submitted. (#42132) (#42132)
As previously discussed in pull/31070 and issues/30486, this would be useful because it is often desirable to apply styles to fields that are both `ng-invalid` and `ng-pristine` after the first attempt at form submission, but Angular does not provide any simple way to do this (although evidently Angularjs did). This will now be possible with a descendant selector such as `.ng-submitted .ng-invalid`.

In this implementation, the directive that sets control status classes on forms and formGroups has its set of statuses widened to include `ng-submitted`. Then, in the event that `is('submitted')` is invoked, the `submitted` property of the control container is returned iff it exists. This is preferred over checking whether the container is a `Form` or `FormGroup` directly to avoid reflecting on those classes.

Closes #30486.
