As of ES2021, JavaScript allows using underscores as separators inside numbers, in order to make them more readable (e.g. `1_000_000` vs `1000000`). TypeScript has had support for separators for a while so these changes expand the template parser to handle them as well.

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).

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.)

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.

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.

element stack of [`li`, `div`] when it encounters the close `li` tag.
We compare against the previously unclosed tag `div` and see that this is
unexpected. Instead of simply giving up here, we continue to move up the
unclosed tags until we find a match (if there is one).

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.
PR Close#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).

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`.
