**Problem**
After #31109 and #31865, it's still possible to get locked in state
`EXISTING_CLIENTS_ONLY`, without any possibility to get out (even by
pushing new updates on the server).
More specifically, if control doc `/latest` of `ngsw:/:db:control` once
gets a bad value, then the service worker will fail early, and won't be
able to overwrite `/latest` with new, valid values (the ones from future
updates).
For example, once in this state, URL `/ngsw/state` will show:
NGSW Debug Info:
Driver state: EXISTING_CLIENTS_ONLY (Degraded due to failed initialization: Invariant violated (initialize): latest hash 8b75… has no known manifest
Error: Invariant violated (initialize): latest hash 8b75… has no known manifest
at Driver.<anonymous> (https://my.app/ngsw-worker.js:2302:27)
at Generator.next (<anonymous>)
at fulfilled (https://my.app/ngsw-worker.js:175:62))
Latest manifest hash: 8b75…
Last update check: 22s971u
... with hash `8b75…` corresponding to no installed version.
**Solution**
Currently, when such a case happens, the service worker [simply fails
with an assertion][1]. Because this failure happens early, and is not
handled, the service worker is not able to update `/latest` to new
installed app versions.
I propose to detect this corrupted case (a `latest` hash that doesn't
match any installed version) a few lines above, so that the service
worker can correctly call its [already existing cleaning code][2].

Previously, event listeners for component output events attached on an
Angular custom element before inserting it into the DOM (i.e. before
instantiating the underlying component) didn't fire for events emitted
during initialization lifecycle hooks, such as `ngAfterContentInit`,
`ngAfterViewInit`, `ngOnChanges` (initial call) and `ngOnInit`.
The reason was that that `NgElementImpl` [subscribed to events][1]
_after_ calling [ngElementStrategy#connect()][2], which is where the
[initial change detection][3] takes place (running the initialization
lifecycle hooks).
This commit fixes this by:
1. Ensuring `ComponentNgElementStrategy#events` is defined and available
for subscribing to, even before instantiating the component.
2. Ensuring `NgElementImpl` subscribes to `NgElementStrategy#events`
before calling `NgElementStrategy#connect()` (which initializes the
component instance).

There is an `exec()` helper provided by `utils/shelljs.ts`, which is a
wrapper around ShellJS' `exec()` with some default options (currently
`silent: true`). The intention is to avoid having to pass these options
to every invocation of the `exec()` function.
This commit updates all code inside `dev-infra/` to use this helper
whenever possible).
NOTE: For simplicity, the `utils/shelljs` helper does not support some
of the less common call signatures of the original `exec()`
helper, so in some cases we still need to use the original.

We recently added a better reporting mechanism for oauth tokens
in the dev-infra git util. Unfortunately the logic broke as part
of addressing PR review feedback. Right now, always the empty
promise from `oauthScopes` will be used as `getAuthScopes` considers
it as the already-requested API value. This is not the case as
the default promise is also truthy. We should just fix this by making
the property nullable.

This finder is designed to only process entry-points that are reachable
by the program defined by a tsconfig.json file.
It is triggered by calling `mainNgcc()` with the `findEntryPointsFromTsConfigProgram`
option set to true. It is ignored if a `targetEntryPointPath` has been
provided as well.
It is triggered from the command line by adding the `--use-program-dependencies`
option, which is also ignored if the `--target` option has been provided.
Using this option can speed up processing in cases where there is a large
number of dependencies installed but only a small proportion of the
entry-points are actually imported into the application.

Previously we only checked for static import declaration statements.
This commit also finds import paths from dynamic import expressions.
Also this commit should speed up processing: Previously we were parsing
the source code contents into a `ts.SourceFile` and then walking the parsed
AST to find import paths.
Generating an AST is unnecessary work and it is faster and creates less
memory pressure to just scan the source code contents with the TypeScript
scanner, identifying import paths from the tokens.

The angular.io production deployment script (`deploy-to-firebase.sh`)
compares the major version corresponding to the current branch (e.g.
`8` for branch `8.1.x`) against the major stable version (e.g. `9` if
the current stable version is `9.1.0`). It then uses the result of that
comparison to determine whether the current branch corresponds to a
newer version than stable (i.e. an RC version) and thus should not be
deployed or to an older version and thus may need to be deployed to an
archive vX.angular.io project.
Previously, the script was using string comparison (`<`) to compare the
two major versions. This could produce incorrect results for an RC major
version that is numerically greater than the stable but
lexicographically smaller. For example, 10 vs 9 (10 is numerically
greater but lexicographically smaller than 9).
Example of a CI job that incorrectly tried to deploy an RC branch to
production: https://circleci.com/gh/angular/angular/726414
This commit fixes it by switching to an integer comparison (i.e. using
the `-lt` operator).

`NgCompiler` is the heart of ngtsc and can be used to analyze and compile
Angular programs in a variety of environments. Most of these integrations
rely on `NgProgram` and the creation of an `NgCompilerHost` in order to
create a `ts.Program` with the right shape for `NgCompiler`.
However, certain environments (such as the Angular Language Service) have
their own mechanisms for creating `ts.Program`s that don't make use of a
`ts.CompilerHost`. In such environments, an `NgCompilerHost` does not make
sense.
This commit breaks the dependency of `NgCompiler` on `NgCompilerHost` and
extracts the specific interface of the host on which `NgCompiler` depends
into a new interface, `NgCompilerAdapter`. This interface includes methods
from `ts.CompilerHost`, the `ExtendedTsCompilerHost`, as well as APIs from
`NgCompilerHost`.
A consumer such as the language service can implement this API without
needing to jump through hoops to create an `NgCompilerHost` implementation
that somehow wraps its specific environment.
PR Close#37118
When the compiler encounters a function call within an NgModule imports
section, it attempts to resolve it to an NgModule-annotated class by
looking at the function body and evaluating the statements there. This
evaluation can only understand simple functions which have a single
return statement as their body. If the function the user writes is more
complex than that, the compiler won't be able to understand it and
previously the PartialEvaluator would return a "DynamicValue" for
that import.
With this change, in the event the function body resolution fails the
PartialEvaluator will now attempt to use its foreign function resolvers to
determine the correct result from the function's type signtaure instead. If
the function is annotated with a correct ModuleWithProviders type, the
compiler will be able to understand the import without static analysis of
the function body.

If we detect that an injectable class is inheriting from another injectable, we generate code that looks something like this:
```
const baseFactory = ɵɵgetInheritedFactory(Child);
@Injectable()
class Parent {}
@Injectable()
class Child extends Parent {
static ɵfac = (t) => baseFactory(t || Child)
}
```
This usually works fine, because the `ɵɵgetInheritedFactory` resolves to the factory of `Parent`, but the logic can break down if the `Child` class has a custom decorator. Custom decorators can return a new class that extends the original once, which means that the `ɵɵgetInheritedFactory` call will now resolve to the factory of the `Child`, causing an infinite loop.
These changes fix the issue by changing the inherited factory resolution logic so that it walks up the prototype chain class-by-class, while skipping classes that have the same factory as the class that was passed in.
Fixes#35733.

Currently, if an ngcc process is killed in a manner that it doesn't clean
up its lock file (or is killed too quickly) the compiler reports that it
is waiting on the PID of a process that doesn't exist, and that it will
wait up to a maximum of N seconds. This PR updates the locking code to
additionally check if the process exists, and if it does not it will
immediately bail out, and print the location of the lock file so a user
may clean it up.

They behave exactly the same way except for `+0`/`-0`.
`looseIdentical(+0, -0)` => `true`
`Object.is(+0, -0)` => `false`
Other than the difference noted above, this is not be a breaking change because:
1. `looseIdentical` is a private API
2. ES2015 is listed as a mandatory polyfill in the [browser support
guide](https://angular.io/guide/browser-support#mandatory-polyfills)
3. Also note that `Ivy` already uses `Object.is` in `bindingUpdated`.
