When ngcc creates an entry-point program, the `allowJs` option is enabled
in order to operate on the JavaScript source files of the entry-point.
A side-effect of this approach is that external modules that don't ship
declaration files will also have their JavaScript source files loaded
into the program, as the `allowJs` flag allows for them to be imported.
This may pose an issue in certain edge cases, where ngcc would inadvertently
operate on these external modules. This can introduce all sorts of undesirable
behavior and incompatibilities, e.g. the reflection host that is selected for
the entry-point's format could be incompatible with that of the external
module's JavaScript bundles.
To avoid these kinds of issues, module resolution that would resolve to
a JavaScript file located outside of the package will instead be rejected,
as if the file would not exist. This would have been the behavior when
`allowJs` is set to false, which is the case in typical Angular compilations.

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 `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. Changing `NgElementImpl` to subscribe to `NgElementStrategy#events`
(if available) before calling `NgElementStrategy#connect()` (which
initializes the component instance) if available.
3. Falling back to the old behavior (subscribing to `events` after
calling `connect()` for strategies that do not initialize `events`
before their `connect()` is run).
NOTE:
By falling back to the old behavior when `NgElementStrategy#events` is
not initialized before calling `NgElementStrategy#connect()`, we avoid
breaking existing custom `NgElementStrategy` implementations (with
@remackgeek's [ElementZoneStrategy][4] being a commonly used example).

If [innerHTML] is used in a component and a Content-Security-Policy is set
that does not allow inline styles then Firefox and Chrome show the following
message:
> Content Security Policy: The page’s settings observed the loading of a
resource at self (“default-src”). A CSP report is being sent.
This message is caused because Angular is creating an inline style tag to
test for a browser bug that we use to decide what sanitization strategy to
use, which causes CSP violation errors if inline CSS is prohibited.
This test is no longer necessary, since the `DOMParser` is now safe to use
and the `style` based check is redundant.
In this fix, we default to using `DOMParser` if it is available and fall back
to `createHTMLDocument()` if needed. This is the approach used by DOMPurify
too.
The related unit tests in `html_sanitizer_spec.ts`, "should not allow
JavaScript execution when creating inert document" and "should not allow
JavaScript hidden in badly formed HTML to get through sanitization (Firefox
bug)", are left untouched to assert that the behavior hasn't changed in
those scenarios.

Special DI tokens like `ChangeDetectorRef` and `ElementRef` can provide a factory via `NG_ELEMENT_ID`. The problem is that we were reading it off the token as `token[NG_ELEMENT_ID]` which will go up the prototype chain if it couldn't be found on the current token, resulting in the private `ViewRef` API being exposed, because it extends `ChangeDetectorRef`.
These changes fix the issue by guarding the property access with `hasOwnProperty`.

This commit fixes a bug whereby the language service would incorrectly

This is because we walk through every possible scenario, and fallback to

we are in a bound text. This means we will now return an empty results if
there is no suggestions.

`getExternalFiles()` is an API that could optionally be provided by a tsserver plugin
to notify the server of any additional files that should belong to a particular project.
This API was removed in https://github.com/angular/angular/pull/34260 mainly
due to performance reasons.
However, with the introduction of "solution-style" tsconfig in typescript 3.9,
the Angular extension could no longer reliably detect the owning Project solely
based on the ancestor tsconfig.json. In order to support this use case, we have
to reinstate `getExternalFiles()`.

Scripts provided in the `ng-dev` command might use local `git`
commands. For such scripts, we keep track of the branch that
has been checked out before the command has been invoked.
We do this so that we can later (upon command completion)

It looks like this logic currently only deals with branches
but does not work properly when a command is invoked from

As of v10, the `undecorated-classes-with-decorated-fields` migration
generally deals with undecorated classes using Angular features. We
intended to run this migation as part of v10 again as undecorated
classes with Angular features are no longer supported in planned v11.
The migration currently behaves incorrectly in some cases where an
`@Injectable` or `@Pipe` decorated classes uses the `ngOnDestroy`
lifecycle hook. We incorrectly add a TODO for those classes. This
commit fixes that.
Additionally, this change makes the migration more robust to
not migrate a class if it inherits from a component, pipe
injectable or non-abstract directive. We previously did not
need this as the undecorated-classes-with-di migration ran
before, but this is no longer the case.
Last, this commit fixes an issue where multiple TODO's could be
added. This happens when multiple Angular CLI build targets have
an overlap in source files. Multiple programs then capture the
same source file, causing the migration to detect an undecorated
class multiple times (i.e. adding a TODO twice).

Commit 4213e8d5 introduced shim reference tagging into the compiler, and
changed how the `TypeCheckProgramHost` worked under the hood during the
creation of a template type-checking program. This work enabled a more
incremental flow for template type-checking, but unintentionally introduced
several regressions in performance, caused by poor incrementality during
`ts.Program` creation.
1. The `TypeCheckProgramHost` was made to rely on the `ts.CompilerHost` to
retrieve instances of `ts.SourceFile`s from the original program. If the
host does not return the original instance of such files, but instead
creates new instances, this has two negative effects: it incurs
additional parsing time, and it interferes with TypeScript's ability to
reuse information about such files.
2. During the incremental creation of a `ts.Program`, TypeScript compares
the `referencedFiles` of `ts.SourceFile` instances from the old program
with those in the new program. If these arrays differ, TypeScript cannot
fully reuse the old program. The implementation of reference tagging
introduced in 4213e8d5 restores the original `referencedFiles` array
after a `ts.Program` is created, which means that future incremental
operations involving that program will always fail this comparison,
effectively limiting the incrementality TypeScript can achieve.
Problem 1 exacerbates problem 2: if a new `ts.SourceFile` is created by the
host after shim generation has been disabled, it will have an untagged
`referencedFiles` array even if the original file's `referencedFiles` was
not restored, triggering problem 2 when creating the template type-checking
program.
To fix these issues, `referencedFiles` arrays are now restored on the old
`ts.Program` prior to the creation of a new incremental program. This allows
TypeScript to get the most out of reusing the old program's data.
Additionally, the `TypeCheckProgramHost` now uses the original `ts.Program`
to retrieve original instances of `ts.SourceFile`s where possible,
preventing issues when a host would otherwise return fresh instances.
Together, these fixes ensure that program reuse is as incremental as
possible, and tests have been added to verify this for certain scenarios.
An optimization was further added to prevent the creation of a type-checking
`ts.Program` in the first place if no type-checking is necessary.

In the process of updating the scripts I rediscovered a bug in the deploy-to-firebase.sh script that
incorrect compared two numbers as strings. This previously worked correctly because we were comparing

strings and numbers. The bug was fixed by switching to an arithmetic comparison of the two variables.
This bug has been fixed on the master branch but not on the 9.1.x branch. I realized this during the

Previously, dev-infra approval (via PullApprove) was required for all
.bazel files in the monorepo, including those in packages/compiler-cli.
The compiler-cli package is a little special in this sense:
* it's not shipped to NPM in the APF
* it uses lots of internal subpackages to organize and test its code
As a result:
* changes to compiler-cli BUILD.bazel files are not user visible and
don't have larger implications for the packages published to NPM,
unlike changes to other BUILD.bazel files in the repo
* the requirement for dev-infra approval for BUILD.bazel changes is
overly burdensome, because compiler-cli build files change more
rapidly than those of other packages.
This commit exempts the compiler-cli's build files from the requirement
for dev-infra approval. It will be sufficient for such files to be
approved by the normal compiler reviewers.
