For quite a while it is an unspoken convention to add a trailing
new-line files within the Angular repository. This was never enforced
automatically, but has been frequently raised in pull requests through
manual review. This commit sets up a lint rule so that this is
"officially" enforced and doesn't require manual review.

Updates the compiler-cli compliance goldens. The golden updates are
required due to a regression in TypeScript 4.3 that causes the emitter
to not incorrectly preserve lines when emitting a node list.
This can be reverted once https://github.com/microsoft/TypeScript/pull/44070
is available.

Switches the repository to TypeScript 4.3 and the latest
version of tslib. This involves updating the peer dependency
ranges on `typescript` for the compiler CLI and for the Bazel
package. Tests for new TypeScript features have been added to
ensure compatibility with Angular's ngtsc compiler.

After testing, it seems that the flakyness we are experiencing in our legacy
saucelabs job is caused by timeouts which happen due to the karma server being
unable to serve all of the files needed for the tests fast enough while concurrent
tests are being run.

With the recent refactorings to `GitClient`, where singletons
are created and can be retrieved through a static method, the
test has been updated to also install spies for the static methods
of `GitClient`. This commit updates the spy installation so that
the same mock git client is used that is also passed manually to
the release actions. Having two separate instances of the mock
git client could result in false-positive test results.
PR Close#42468
Currently the `GitClient` accepts a generic parameter for determining
whether the `githubToken` should be set or not. This worked fine so far
in terms of distinguishing between an authenticated and
non-authenticated git client instance, but if we intend to conditionally
show methods only for authenticated instances, the generic parameter
is not suitable.
This commit splits up the `GitClient` into two classes. One for
the base logic without any authorization, and a second class that
extends the base logic with authentication logic. i.e. the
`AuthenticatedGitClient`. This allows us to have specific methods only
for the authenticated instance. e.g.
* `hasOauthScopes` has been moved to only exist for authenticated
instances.
* the GraphQL functionality within `gitClient.github` is not
accessible for non-authenticated instances. GraphQL API requires
authentication as per Github.
The initial motiviation for this was that we want to throw if
`hasOAuthScopes` is called without the Octokit instance having
a token configured. This should help avoiding issues as within
https://github.com/angular/angular/commit/3b434ed94d9ed067e5d999c064ae5f12b3cb175c
that prevented the caretaker process momentarily.
Additionally, the Git client has moved from `index.ts` to
`git-client.ts` for better discoverability in the codebase.

Previously, the critical CSS inlining optimization (which is turned on
by default in CLI v12+) was causing a Flash Of Unstyled Content (FOUC).
This was caused by the combination of the following facts:
- The way CSS inlining is implemented in the CLI makes loading the full
styles asynchronous and non-render-blocking (so the app can bootstrap
before the styles are fully downloaded).
- Angular.io does not employ the [app shell][1] pattern in order to
render pages at build time, resulting in very minimal CSS rules being
recognized as critical (for the purpose of inlining).
This commit fixes the FOUC by disabling the critical CSS inlining, while
we consider a better way to approach this (in order to be able to rip
the benefits of inlining without the FOUC).

Currently we support safe property (`a?.b`) and method (`a?.b()`) accesses, but we don't handle safe keyed reads (`a?.[0]`) which is inconsistent. These changes expand the compiler in order to support safe key read expressions as well.
PR Close#41911
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.

In the dev-infra merge tool, a test fails locally if it runs on
a system with a different system locale. We can either make the
test more flexible, or update the merge tool to always print the date
in `en-US` format. The latter is more reasonable given our console
messages being in english anyway.

With the removal of the `ModuleWithProviders` transform in the parent commit,
the underlying dts transform can also be removed as it is not used elsewhere.
PR Close#41996
The `ModuleWithProviders` type has required a generic type since Angular 10,
so it is no longer necessary for the compiler to transform usages of the
`ModuleWithProviders` type without the generic type, as that should have
been reported as a compile error. This commit removes the detection logic
from ngtsc.
PR Close#41996
Prior to this change the `min` and `max` validator directives would not
set the `min` and `max` attributes on the host element. The problem was
caused by the truthy check in host binding expression that was
calculated as `false` when `0` is used as a value. This commit updates
the logic to leverage nullish coalescing operator in these host binding
expressions, so `0` is treated as a valid value, thus the `min` and
`max` attributes are set correctly.

When a `trackBy` function is used that accepts a supertype of the iterated
array's type, the loop variable would undesirably be inferred as the supertype
instead of the array's item type. This commit adds an inferred type parameter
to `TrackByFunction` to allow an extra degree of freedom, enabling the
loop value to be inferred as the most narrow type.

The ngtsc test targets have fake declarations files for `@angular/core`
and `@angular/common` and the template type checking tests can leverage
the fake common declarations instead of declaring its own types.
PR Close#41995
Type-only imports are known to be elided by TypeScript, so the compiler
can be certain that such imports do not contribute to potential import
cycles. As such, type-only imports are no longer considered during cycle
analysis.
Regular import statements that would eventually be fully elided by
TypeScript during emit if none of the imported symbols are used in a
value position continue to be included in the cycle analysis, as the
cycle analyzer is unaware of these elision opportunities. Only explicit
`import type` statements are excluded.

The shared dev-infra package from `HEAD` should not be installed
when running the `components-repo-unit-tests` job. This is done
because otherwise changes to the dev-infra package can result in

is to test the framework)

This change moves the `dev-infra/browsers` folder into `dev-infra/bazel`.
The browser folder is providing custom configuration for Bazel, so it

Removes the duplicate `hasLocalChanges` method from the Git client. We
already have `hasUncommittedChanges`. Also removes a TODO for adding
`assertNoLocalChanges` as it seems more flexible to manually check
(i.e. better messaging with context on the current tool; e.g. "cannot
perform rebase")
