Bump Chrome to the next stable release (84.0.4147) by following the
instructions in dev-infra/browsers/README.md.
With Chrome 86 about to be released as stable, the current local version
(Chrome 83) is starting to lag behind. It also contains a bug that
blocks Angular unit and integration tests from using Trusted Types.

Expressions within ICU expressions in templates were not previously
type-checked, as they were skipped while traversing the elements
within a template. This commit enables type checking of these
expressions by actually visiting the expressions.
BREAKING CHANGE:
Expressions within ICUs are now type-checked again, fixing a regression
in Ivy. This may cause compilation failures if errors are found in
expressions that appear within an ICU. Please correct these expressions
to resolve the type-check errors.
Fixes#39064
PR Close#39072
Prior to this change, expressions within ICUs would have a source span
corresponding with the whole ICU. This commit narrows down the source
spans of these expressions to the exact location in the source file, as
a prerequisite for reporting type check errors within these expressions.

Updates to rules_nodejs 2.2.0. This is the first major release in 7 months and includes a number of features as well
as breaking changes.
Release notes: https://github.com/bazelbuild/rules_nodejs/releases/tag/2.0.0
Features of note for angular/angular:
* stdout/stderr/exit code capture; this could be potentially be useful
* TypeScript (ts_project); a simpler tsc rule that ts_library that can be used in the repo where ts_library is too
heavy weight
Breaking changes of note for angular/angular:
* loading custom rules from npm packages: `ts_library` is no longer loaded from `@npm_bazel_typescript//:index.bzl`
(which no longer exists) but is now loaded from `@npm//@bazel/typescript:index.bzl`
* with the loading changes above, `load("@npm//:install_bazel_dependencies.bzl", "install_bazel_dependencies")` is
no longer needed in the WORKSPACE which also means that yarn_install does not need to run unless building/testing
a target that depends on @npm. In angular/angular this is a minor improvement as almost everything depends on @npm.
* @angular/bazel package is also updated in this PR to support the new load location; Angular + Bazel users that
require it for ng_package (ng_module is no longer needed in OSS with Angular 10) will need to load from
`@npm//@angular/bazel:index.bzl`. I investigated if it was possible to maintain backward compatability for the old
load location `@npm_angular_bazel` but it is not since the package itself needs to be updated to load from
`@npm//@bazel/typescript:index.bzl` instead of `@npm_bazel_typescript//:index.bzl` as it depends on ts_library
internals for ng_module.
* runfiles.resolve will now throw instead of returning undefined to match behavior of node require
Other changes in angular/angular:
* integration/bazel has been updated to use both ng_module and ts_libary with use_angular_plugin=true.
The latter is the recommended way for rules_nodejs users to compile Angular 10 with Ivy. Bazel + Angular ViewEngine is
supported with @angular/bazel <= 9.0.5 and Angular <= 8. There is still Angular ViewEngine example on rules_nodejs
https://github.com/bazelbuild/rules_nodejs/tree/stable/examples/angular_view_engine on these older versions but users
that want to update to Angular 10 and are on Bazel must switch to Ivy and at that point ts_library with
use_angular_plugin=true is more performant that ng_module. Angular example in rules_nodejs is configured this way
as well: https://github.com/bazelbuild/rules_nodejs/tree/stable/examples/angular. As an aside, we also have an
example of building Angular 10 with architect() rule directly instead of using ts_library with angular plugin:
https://github.com/bazelbuild/rules_nodejs/tree/stable/examples/angular_bazel_architect.
NB: ng_module is still required for angular/angular repository as it still builds ViewEngine & @angular/bazel
also provides the ng_package rule. ng_module can be removed in the future if ViewEngine is no longer needed in
angular repo.
* JSModuleInfo provider added to ng_module. this is for forward compat for future rules_nodejs versions.

This is a roll forward of #39082, using `ts.createIdentifier(`'legacy'`)` as a cross-version compatible way of making

This PR enables `getSemanticDiagnostics()` to be called on external templates.
Several changes are needed to land this feature:
1. The adapter needs to implement two additional methods:
a. `readResource()`
Load the template from snapshot instead of reading from disk
b. `getModifiedResourceFiles()`
Inform the compiler that external templates have changed so that the
loader could invalidate its internal cache.
2. Create `ScriptInfo` for external templates in MockHost.
Prior to this, MockHost only track changes in TypeScript files. Now it
needs to create `ScriptInfo` for external templates as well.
For (1), in order to make sure we don't reload the template if it hasn't
changed, we need to keep track of its version. Since the complexity has
increased, the adapter is refactored into its own class.

With this change we add a short url to strict mode guide
(angular.io/strict -> angular.io/guide/strict-mode). This is important because
of two reasons.
1) Reduce the clutter in the terminal when we include the strict mode guide url in a prompt.
2) Easiler to share in conferences, slides etc..

The right needs to be wrapped in parens or we cannot accurately match its
span to just the RHS. For example, the span in `e = $event /*0,10*/` is ambiguous.
It could refer to either the whole binary expression or just the RHS.
We should instead generate `e = ($event /*0,10*/)` so we know the span 0,10 matches RHS.
This is specifically needed for the TemplateTypeChecker/Language Service
when mapping template positions to items in the TCB.

As of #32671, the type of `AbstractControl.parent` can be null which can cause
compilation errors in existing apps. These changes add a migration that will append
non-null assertions to existing unsafe accesses.
````
// Before
console.log(control.parent.value);
// After
console.log(control.parent!.value);
```
The migration also tries its best to avoid cases where the non-null assertions aren't
necessary (e.g. if the `parent` was null checked already).

This commit introduces a new API for the `TemplateTypeChecker` which allows
for autocompletion in a global expression context (for example, in a new
interpolation expression such as `{{|}}`). This API returns instances of the
type `GlobalCompletion`, which can represent either a completion result from
the template's component context or a declaration such as a local reference
or template variable. The Language Service will use this API to implement
autocompletion within templates.
PR Close#39048
The template binding API in @angular/compiler exposes information about a
template that is synthesized from the template structure and its scope
(associated directives and pipes).
This commit introduces a new API, `getEntitiesInTemplateScope`, which
accepts a `Template` object (or `null` to indicate the root template) and
returns all `Reference` and `Variable` nodes that are visible at that level
of the template, including those declared in parent templates.
This API is needed by the template type-checker to support autocompletion
APIs for the Language Service.

Previously the value passed to `AstFactory.attachComments()` could be
`undefined` which is counterintuitive, since why attach something that
doesn't exist? Now it expects there to be a defined array. Further it no
longer returns a statement. Both these aspects of the interface were designed
to make the usage simpler but has the result of complicating the implemenation.
The `ExpressionTranslatorVisitor` now has a helper function (`attachComments()`)
to handle `leadingComments` being undefined and also returning the statement.
This keeps the usage in the translator simple, while ensuring that the `AstFactory`
API is not influenced by how it is used.

Prior to this change, the `validators` and `asyncValidators` fields of a few Forms directives
were typed as `any[]`. This commit updates the types and makes them consistent for all directives
in the Forms package.
BREAKING CHANGE:
Directives in the `@angular/forms` package used to have `any[]` as a type of `validators` and
`asyncValidators` arguments in constructors. Now these arguments are properly typed, so if your
code relies on directive constructor types it may require some updates to improve type safety.

This is needed so that the Language Service can provide the module name
in the quick info for a directive/component.
To accomplish this, the compiler's `LocalModuleScope` is provided to the
`TemplateTypeCheckerImpl`. This will also allow the `TemplateTypeChecker` to
provide more completions in the future, giving it a way to determine all the
directives/pipes/etc. available to a template.
PR Close#39099
The expression parser already has support for recovering on malformed
property reads, but did not have tests describing the recovered ast in
such cases. This commit adds tests to demonstrate such cases; in
particular, the recovered ast is a full PropertyRead but with an empty
property name. This is likely the most preferred option, as it does not
constrain consumers of the AST to what the property name should look
like. Furthermore, we cannot mark the property name as empty in any
other way (e.g. an EmptyExpr) because the property name, as of present,
is a string field rather than an AST itself.
Note that tokens past a malformed property read are not preserved in the
AST (for example in `foo.1234`, `1234` is not preserved in the AST).
This is because the extra tokens do not belong to the singular
expression created by the property read, and there is not a meaningful
way to interpret a secondary expression in a single parsed expression.

Close#38851, support `jest` fakeTimers APIs' integration with `fakeAsync()`.
After enable this feature, calling `jest.useFakeTimers()` will make all test
run into `fakeAsync()` automatically.

- `jest.runAllTimers()` will call `flush()`.
- `jest.advanceTimersByTime()` will call `tick()`
- `jest.runOnlyPendingTimers()` will call `flushOnlyPendingTimers()`
- `jest.advanceTimersToNextTimer()` will call `tickToNext()`
- `jest.clearAllTimers()` will call `removeAllTimers()`

It's perfectly valid for an abstract control not to have a defined parent; yet previously the
types were asserting that AbstractControl#parent is not a null value. This changes correctly
reflects the run-time behavior through the types.
BREAKING CHANGE: Type of AbstractFormControl.parent now includes null
`null` is now included in the types of .parent. If you don't already have a check for this case,
the TypeScript compiler might compain. A v11 migration exists which adds the not-null assertion
operator where necessary.
In an unlikely case your code was testing the parnet against undefined with sitrct equality,
you'll need to change this to `=== null` instead, since the parent is not explicily initialized
with `null` instead of being left `undefined`.

This patch refactors the interpolation parser to do so iteratively
rather than using a regex. Doing so prepares us for supporting granular
recovery on poorly-formed interpolations, for example when an
interpolation does not terminate (`{{ 1 + 2`) or is not terminated
properly (`{{ 1 + 2 {{ 2 + 3 }}`).

The compiler maintains an internal dependency graph of all resource
dependencies for application source files. This information can be useful
for tools that integrate the compiler and need to support file watching.
This change adds a `getResourceDependencies` method to the
`NgCompiler` class that allows compiler integrations to access resource
dependencies of files within the compilation.
PR Close#38048
This patch adds support for recovering well-formed (and near-complete)
ASTs for semantically malformed keyed reads and keyed writes. See the
added tests for details on the types of semantics we can now recover;
in particular, notice that some assumptions are made about the form of
a keyed read/write intended by a user. For example, in the malformed
expression `a[1 + = 2`, we assume that the user meant to write a binary
expression for the key of `a`, and assign that key the value `2`. In
particular, we now parse this as `a[1 + <empty expression>] = 2`. There
are some different interpretations that can be made here, but I think
this is reasonable.
The actual changes in the parser code are fairly minimal (a nice
surprise!); the biggest addition is a `writeContext` that marks whether
the `=` operator can serve as a recovery point after error detection.

Previously, when a heading was longer than the Table of Content's (TOC)
width and it had to be wrapped into multiple lines, it was hard to
distinguish the subsequent lines from other TOC entries (i.e. other
headings).
This commit makes it easier to visually distinguish wrapped heading
lines from other headings by reducing the spacing between wrapped lines
of the same heading (making it more obvious that they belong together).
