This commit updates the Testability-related tests to reset the testability getter class after each test to avoid leaking the state between tests. This should improve the stability of the testability tests that are currently flaky on CI.
PR Close#45947
The Testability-related logic was refactored in https://github.com/angular/angular/pull/45657 to become tree-shaking-friendly: it was decoupled from the core providers of the `BrowserModule`. This commit updates the newly-introduced `bootstrapApplication` function to exclude Testability-providers by default (note: the Testability is still included in the NgModule-based bootstrap).
In order to add the Testability to the app bootstrapped via `bootstrapApplication`, the `provideProtractorTestingSupport` function is introduced.

Previously, using `FormBuilder` with a union type would produce unions of *controls*:
```
// `foo` has type `FormControl<string>|FormControl<number>`.
const c = fb.nonNullable.group({foo: 'bar' as string | number});
```
This actually works in many cases, due to how extraordinarily powerful Typescript's distributive types are (e.g. `value` still has type `string|number`), but it is subtly incorrect. Here is a code example that exposes the reason the inference is incorrect. It exploits the fact that Typescript will not "un-distribute" a type, producing an obviously spurious error:
```
// fc gets an inferred distributive union type `FormControl<string> | FormControl<number>`
let fc = c.controls.foo;
// Error: Type 'FormControl<string | number>' is not assignable to type 'FormControl<string> | FormControl<number>'.
fc = new FormControl<string|number>('', {initialValueIsDefault: true});
```
Instead, we want the union to apply to the *values*:
```
// `foo` should have type `FormControl<string|number>`.
const c = fb.nonNullable.group({foo: 'bar' as string | number});
```
Essentially, we want to prevent Typescript from distributing the type. [As specified in the handbook](https://www.typescriptlang.org/docs/handbook/2/conditional-types.html#distributive-conditional-types):
> Typically, distributivity is the desired behavior. To avoid that behavior, you can surround each side of the extends keyword with square brackets.
This PR applies this suggestion to `FormBuilder`'s type inference.

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`.

When an external template is read, adds the template file to to the project which contains.
This is necessary to keep the projects open when navigating away from HTML files.
Since a `tsconfig` cannot express including non-TS files,
we need another way to indicate the template files are considered part of the project.
Note that this does not ensure that the project in question _directly_ contains the component
file. That is, the project might just include the component file through the program rather
than directly in the `include` glob of the `tsconfig`. This distinction is somewhat important
because the TypeScript language service/server prefers projects which _directly_ contain the TS
file (see `projectContainsInfoDirectly` in the TS codebase). What this means it that there can
possibly be a different project used between the TS and HTML files.
For example, in Nx projects, the referenced configs are `tsconfig.app.json` and
`tsconfig.editor.json`. `tsconfig.app.json` comes first in the base `tsconfig.json` and
contains the entry point of the app. `tsconfig.editor.json` contains the `**.ts` glob of all TS
files. This means that `tsconfig.editor.json` will be preferred by the TS server for TS files
but the `tsconfig.app.json` will be used for HTML files since it comes first and we cannot
effectively express `projectContainsInfoDirectly` for HTML files.
We could consider also updating the language server implementation to attempt
to select the project to use for the template file based on which project
contains its component file directly, using either the internal `project.projectContainsInfoDirectly`
or as a workaround, check `project.isRoot(componentTsFile)`.
Finally, keeping the projects open is hugely important in the solution style config case like
Nx. When a TS file is opened, TypeScript will only retain `tsconfig.editor.json` and not
`tsconfig.app.json`. However, if our extension does not also know to select
`tsconfig.editor.json`, it will automatically select `tsconfig.app.json` since it is defined
first in the `tsconfig.json` file. So we need to teach TS server that we are (1) interested in
keeping projects open when there is an HTML file open and (2) optionally attempt to do this
_only_ for projects that we know the TS language service will prioritize in TS files (i.e.,
attempt to only keep `tsconfig.editor.json` open and allow `tsconfig.app.json` to close)
and prioritize that project for all requests.

In PR #45349 we switched to using version 2 of the CircleCI API. It
turns out that this version of the API (in addition to different URLs)
also returns different info from some endpoints, which we have failed to
account for.
More specifically, the v2 API response for a job does not contain info
that we need in [BuildRetriever][1].
As an example, see the API responses for an `aio_preview` run:
- [API v1.1][2]
- [API v2][3]
This commit updates the code to handle API v2 responses. In addition,
since the info we need is not present in the job info (as it was with
the previous version of the API), we now also retrieve the pipeline
info.
NOTE:
This issue did not manifest earlier, because the preview server code on
the VM was not updated to the latest version (that tried to use API v2)
due to a different error. This error was fixed with PR #45895, which
allowed the preview server to be updated on the VM and uncovered the API
v2 incompatibility.

However, the content that is embedded into `<code-example>` tags via

In PR #45405, the Angular Package Format (APF) was updated so that
secondary entry-points (such as `@angular/common/http`) do not have
their own `package.json` file, as they used to. Instead, the paths to
their various formats and types are exposed via the primary
`package.json` file's `exports` property. As an example, see the v13
[@angular/common/http/package.json][1] and compare it with the v14
[@angular/common/package.json > exports][2].
Previously, `ngcc` was not able to analyze such v14+ entry-points and
would instead error as it considered such entry-points missing.
This commit addresses the issue by detecting this situation and
synthesizing a `package.json` file for the secondary entry-points based
on the `exports` property of the primary `package.json` file. This data
is only used by `ngcc` in order to determine that the entry-point does
not need further processing, since it is already in Ivy format.
