Karma jasmine updated the `jasmine-core` dependency. Jasmine is now more
strict when:
* The done callback is invoked multiple times
* The done callback is used, while a promise is also returned
* The done callback is treated as error when e.g. a number is returned
as first argument. This was the case with `requestAnimationFrame`.
This commit migrates any remaining Angular tests which are using some form
of Renderer3 interfaces. Instead, they're switched to Renderer2.
PR Close#46646
Due to the restrictions of circular dependency checking, we need a separate
internal interface for a renderer. We cannot use `Renderer2` as a type
internally as even importing it as a type incurs a dependency on its
implementation, which creates a major potential for circular dependencies.
Previously this role was served by the `Renderer3` type. As we prepare to
remove the `Renderer3` abstraction (the idea of using `document` as a
differently-shaped renderer), this commit renames `ProceduralRenderer3` to
the more generic term `Renderer`.
`RendererFactory3` is also renamed to the more generic `RendererFactory` for
consistency.

This commit updates various tests to use TestBed instead of hand-written instructions, which makes tests easier to maintain and allows to perform further cleanup.
PR Close#46561
The `Renderer3` abstraction in Angular was an experimental code path in Ivy
which uses direct DOM operations instead of the former `Renderer2` path. To
allow `Renderer2` to tree-shake away, `Renderer3` is the default _unless_
`Renderer2` is provided. It was only an experiment, and never meant to be a
production code path.
However, it's possible for `Renderer3` to leak into user code. This commit
prevents that possibility by causing the `Renderer3` path to throw, unless
an explicit function has been called to enable it.
PR Close#46530
This commit updates a set of tests to avoid using hand-written instructions and replace them with TestBed APIs. Some tests were moved to the `acceptance` folder to colocate them with other renderer-related tests.

di_spec.ts was using handwritten definitions and the `renderComponent`-based

This commit updates it to:
* remove unnecessary tests ("limp mode" DI, Renderer3, etc)
* convert other tests to use JIT-compiled classes and not handwritten defs

This commit convers the providers_helper utility function
`expectProvidersScenario` to use the TestBed internally instead of
`ComponentFixture` and handwritten defs. This required several adjustments:
* Making the `ngModule`s passed in to the helper utility real NgModules.
* Using `ViewEncapsulation.None` for the test components (stabilizes the
generated HTML).
* Convert handwritten test components & directives into JIT-compiled
standalone equivalents.

We've had a TODO to expose ManualOnPush for a long time, but it hasn't moved since then. These changes remove it since it would be easy to re-introduce if we wanted to, it frees up an extra space in the flags bitmap and it removes some `render3` tests that we won't have to migrate to `TestBed`.

The NodeJS Bazel linker does not work well on Windows because there
is no sandboxing and linker processes from different tests will attempt
to modify the same `node_modules`, causing concurrency race conditions
and resulting in flakiness.
PR Close#45872
Adds support for TypeScript 4.7. Changes include:
* Bumping the TS version as well as some Bazel dependencies to include https://github.com/bazelbuild/rules_nodejs/pull/3420.
* Adding a backwards-compatibility layer for calls to `updateTypeParameterDeclaration`.
* Making `LView` generic in order to make it easier to type the context based on the usage. Currently the context can be 4 different types which coupled with stricter type checking would required a lot of extra casting all over `core`.
* Fixing a bunch of miscellaneous type errors.
* Removing assertions of `ReferenceEntry.isDefinition` in a few of the language service tests. The field isn't returned by TS anymore and we weren't using it for anything.
* Resolving in error in the language service that was caused by TS attempting to parse HTML files when we try to open them. Previous TS was silently setting them as `ScriptKind.Unknown` and ignoring the errors, but now it throws. I've worked around it by setting them as `ScriptKind.JSX`.

This commit reorganizes the tests around the EnvironmentInjector and its use
for standalone injectors, and adds a number of new test cases.
PR Close#45687
This commit implements the `StandaloneFeature` which provides for the
creation of standalone injectors, for those components which need them. The
feature-based implementation ensures the machinery for standalone injectors
is properly tree-shakable.

This commit extracts the `importProvidersFrom` function and associated
machinery into a separate file, as opposed to being colocated with
`R3Injector`. Separating these functions will mitigate potential future
circular dependencies as `importProvidersFrom` starts being used in
different parts of the codebase.

Previously, the compiler would represent template dependencies of a
component in its component definition through separate fields (`directives`,
`pipes`).
This commit refactors the compiler/runtime interface to use a single field
(`dependencies`). The runtime component definition object still has separate
`directiveDefs` and `pipeDefs`, which are calculated from the `dependencies`
when the definition is evaluated.
This change is also reflected in partially compiled declarations. To ensure
compatibility with partially compiled code already on NPM, the linker
will still honor the old form of declaration (with separate fields).

When we have an event listener inside an embedded view, we generate a `restoreView` call which saves the view inside of the LFrame. The problem is that we don't clear it until it gets overwritten which can lead to memory leaks.
These changes rework the generated code in order to generate a `resetView` call which will clear the view from the LFrame.
Fixes#42848.
PR Close#43075
Angular contains an NgModule registry, which allows a user to declare
NgModules with string ids and retrieve them via those ids, using the
`getNgModuleById` API.
Previously, we attempted to structure this registration in a clever fashion
to allow for tree-shaking of registered NgModules (that is, those with ids).
This sort of worked due to the accidental alignment of behaviors from the
different tree-shakers involved. However, this trick relies on the
generation of `.ngfactory` files and how they're specifically processed in
various bundling scenarios. We intend to remove `.ngfactory` files, hence
we can no longer rely on them in this way.
The correct solution here is to recognize that `@NgModule({id})` is
inherently declaring a global side-effect, and such classes should not
really be eligible for tree-shaking in the first place. This commit removes
all the old registration machinery, and standardizes on generating a side-
effectful call to `registerNgModuleType` for NgModules that have ids.
There is some risk here that NgModules with unnecessary `id`s may not
tree-shake as a result of this change, whereas they would have in previous
circumstances. The fix here should be to remove the `id` if it's not needed.
Specifying an `id` is a request that the NgModule be retained regardless of
any other references, in case it is later looked up by string id.

Adds support for passing in an optional injector when creating an embedded view through `ViewContainerRef.createEmbeddedView` and `TemplateRef.createEmbeddedView`. The injector allows for the DI behavior to be customized within the specific template.
This is a second stab at the changes in #44666. The difference this time is that the new injector acts as a node injector, rather than a module injector.

These changes combine #41358 and #41894.
Currently we save a reference to an `LView` on most DOM nodes created by Angular either by saving the `LView` directly in the `__ngContext__` or by saving the `LContext` which has a reference to the `LView`. This can be a problem if the DOM node is retained in memory, because the `LView` has references to all of the child nodes of the view, as well as other internal data structures.
Previously we tried to resolve the issue by clearing the `__ngContext__` when a node is removed (see https://github.com/angular/angular/pull/36011), but we decided not to proceeed, because it can slow down destruction due to a megamorphic write.
These changes aim to address the issue while reducing the performance impact by assigning a unique ID when an `LView` is created and adding it to `__ngContext__`. All active views are tracked in a map where their unique ID is used as the key. We don't need to worry about leaks within that map, because `LView`s are an internal data structure and we have complete control over when they are created and destroyed.
Fixes#41047.

To make our test output i.e. devmode output more aligned
with what we produce in the NPM packages, or to be more
aligned with what Angular applications will usually consume,
the devmode output is switched from ES5 to ES2015.
Additionally various tsconfigs (outside of Bazel) have been
updated to match with the other parts of the build. The rules
are:
ES2015 for test configurations, ES2020 for actual code that will
end up being shipped (this includes the IDE-only tsconfigs).

The `ng_rollup_bundle` rule has been replaced with a new rule called
`app_bundle`. This rule replicates the Angular v13 optimization
pipeline in the CLI, so that we can get better benchmarking results.
Also the rule is much simpler to maintain as it relies on ESbuild.
The old `ng_rollup_bundle` rule did rely on e.g. build-optimizer that no
longer has an effect on v13 Angular packages, so technically size
tests/symbol tests were no longer as correct as they were before. This
commit fixes that.
A couple of different changes and their explanation:
* Language-service will no longer use the benchmark rule for creating
its NPM bundles! It will use plain `rollup_bundle`. ESBuild would have
been nice but the language-service relies on AMD that ESBuild cannot
generate (yet?)
* Service-worker ngsw-worker.js file was generated using the benchmark
bundle rule. This is wrong. We will use a simple ESbuild rule in the
future. The output is more predictable that way, and we can have a
clear use of the benchmark bundle rule..
* A couple of benchmarks in `modules/` had to be updated to use e.g.
`initTableUtils` calls. This is done because with the new rule, all
files except for the entry-point are considered side-effect free. The
utilities for benchmarks relied on side-effects in some
transitively-loaded file (bad practice anyway IMO). We are now
initializing the utilities using a proper init function that is
exported...

Fixes an issue where destroy hooks are not set up for `useClass` providers
that rely on `forwardRef` for passing the actual class reference.
Currently the destroy hooks are not captured because forward refs are
not resolved for class providers. In ES2015+ this issue becomes even
more critical if arrow-functions are used for
e.g. `useClass: () => forwardRef(..)`.
This is because arrow functions do not have a prototype, unlike in ES5
where the function assigned to `useClass` would always have a prototype.
In ES2015+ a runtime exception as followed is returned (and doesn't give
any useful indication of the forwardRef issue):

Bundle spec files similar to how it is done within the Angular
Components repo. This should simplify the setup and also speed
up the Saucelab job as only a single spec bundle would need to be
downloaded, compared to having to load hundreds of files through the
Saucelabs tunnel.
Also makes a couple of tests more robust with the emulators/and accounts
for ES2015 test runner changes. The tests should be less reluctant to
such build process changes.
Note for reviewers: Some imports have been simplified here. This work
came from Joey's original WIP for this. It's unclear to me whether this
is still needed, but it sounded like this was necessary for the ESBuild
bundling to work. I have robusted the module resolution plugin though,
so I doubt it's still needed. At the same time though: Not worth
reverting/trying as these changes are nice to have anyway!
