Andrew Kushnir 0a1a989fa9 perf(core): avoid recursive scope recalculation when TestBed.overrideModule is used (#35454)
Currently if TestBed detects that TestBed.overrideModule was used for module X, transitive scopes are recalculated recursively for all modules that X imports and previously calculated data (stored in cache) is ignored. This behavior was introduced in https://github.com/angular/angular/pull/33787 to fix stale transitive scopes issue (cache was not updated if module overrides are present).

The perf issue comes from a "diamond" problem, where module X is overridden which imports modules A and B, which both import module C. Under previous logic, module C gets its transitive deps recomputed multiple times, during the recompute for both A and B. For deep graphs and big common/shared modules this can be super costly.

This commit updates the logic to recalculate ransitive scopes for the overridden module, while keeping previously calculated scopes of other modules untouched.

the imported ModuleWithProviders and the parent and getting an extra

Miško Hevery 5aabe93abe refactor(ivy): Switch styling to new reconcile algorithm (#34616)
NOTE: This change must be reverted with previous deletes so that it code remains in build-able state.

This change deletes old styling code and replaces it with a simplified styling algorithm.

The mental model for the new algorithm is:
- Create a linked list of styling bindings in the order of priority. All styling bindings ere executed in compiled order and than a linked list of bindings is created in priority order.
- Flush the style bindings at the end of `advance()` instruction. This implies that there are two flush events. One at the end of template `advance` instruction in the template. Second one at the end of `hostBindings` `advance` instruction when processing host bindings (if any).
- Each binding instructions effectively updates the string to represent the string at that location. Because most of the bindings are additive, this is a cheap strategy in most cases. In rare cases the strategy requires removing tokens from the styling up to this point. (We expect that to be rare case)S Because, the bindings are presorted in the order of priority, it is safe to resume the processing of the concatenated string from the last change binding.

Igor Minar 63c9c2d2be fix: work around 'noImplicityAny' incompatibility due to ts3.7 update (#34798)
Typescript 3.7 now emits d.ts files for getters differently than prior versions,
and there seems to be a bug in how it strips private types without replacing them
with explicit 'any' type. This then leads to compilation failures in projects compiled
against our packages that don't have skipLibCheck turned on but do have strict or
noImplicitAny check on.

I'm working around this by marking the affected getters as @internal and
adding a test to prevent future regressions.

crisbeto 5b864ede13 fix(ivy): TestBed not unwrapping imports array function when overriding provider (#34629)
Fixes an error that is thrown when a provider is overridden in `TestBed`, if the module definition of one of the imported modules uses a function for the `imports` that is set via `setNgModuleScope`. The problem was that we have a `for...of` loop that assumes that the imports are an array, but they can also be a function. This was handled correctly in other places, but this one was missed.

Note that the above-mentioned error is only thrown at runtime when the code is transpiled to es6. In es5 TS generates a call to a helper that handles the error silently so the attached unit test only fails in es6.

Fixes #34623.

That leads to some cryptic error messages (when TestBed tries to compile a Type without having metadata) in case TestBed override functions receive unexpected Types (for example a Directive is used in `TestBed.overrideComponent` call).

Andrew Kushnir fd83d9479a fix(ivy): avoid using stale cache in TestBed if module overrides are defined (#33787)

Module overrides (defined via TestBed.overrideModule) may invalidate this data by adding/removing items in `declarations` list.

Andrew Scott 63256b511a fix(ivy): Only restore registered modules if user compiles modules with TestBed (#32944)
There are a couple scenarios that are problematic and need special
handling:

1. A user has a custom implementation of lazy-loaded modules, sets some
provider overrides, then compiles the module so it can be loaded. In a
follow-up test, the user sets different overrides for the module and
then compiles. This is problematic because we need to be sure the module
registered in the first test is not used, so we need to clear it out of
the modules list in `ng_module_factory_registration`.
2. A user has a similar lazy-loaded module factory implementation but
relies on the module being registered automatically. This can happen,
for example, as a side effect of importing the ngfactory file.

Pete Bacon Darwin fa79f51645 refactor(ivy): update the compiler to emit `$localize` tags (#31609)
This commit changes the Angular compiler (ivy-only) to generate `$localize`
tagged strings for component templates that use `i18n` attributes.

BREAKING CHANGE

Since `$localize` is a global function, it must be included in any applications
that use i18n. This is achieved by importing the `@angular/localize` package
into an appropriate bundle, where it will be executed before the renderer
needs to call `$localize`. For CLI based projects, this is best done in
the `polyfills.ts` file.

```ts
import '@angular/localize';
```

For non-CLI applications this could be added as a script to the index.html
file or another suitable script file.

Olivier Combe 5e0f982961 feat(ivy): use i18n locale data to determine the plural form of ICU expressions (#29249)
Plural ICU expressions depend on the locale (different languages have different plural forms). Until now the locale was hard coded as `en-US`.
For compatibility reasons, if you use ivy with AOT and bootstrap your app with `bootstrapModule` then the `LOCALE_ID` token will be set automatically for ivy, which is then used to get the correct plural form.
If you use JIT, you need to define the `LOCALE_ID` provider on the module that you bootstrap.
For `TestBed` you can use either `configureTestingModule` or `overrideProvider` to define that provider.
If you don't use the compat mode and start your app with `renderComponent` you need to call `ɵsetLocaleId` manually to define the `LOCALE_ID` before bootstrap. We expect this to change once we start adding the new i18n APIs, so don't rely on this function (there's a reason why it's a private export).

Alex Rickabaugh deb77bd3df feat(ivy): TestBed support for reusing non-exported components (#30578)
This is a new feature of the Ivy TestBed.

A common user pattern is to test one component with another. This is
commonly done by creating a `TestFixture` component which exercises the
main component under test.

This pattern is more difficult if the component under test is declared in an
NgModule but not exported. In this case, overriding the module is necessary.

In g3 (and View Engine), it's possible to use an NgSummary to override the
recompilation of a component, and depend on its AOT compiled factory. The
way this is implemented, however, specifying a summary for a module
effectively overrides much of the TestBed's other behavior. For example, the
following is legal:

```typescript
TestBed.configureTestingModule({
  declarations: [FooCmp, TestFixture],
  imports: [FooModule],
  aotSummaries: [FooModuleNgSummary],
});
```

Here, `FooCmp` is declared in both the testing module and in the imported
`FooModule`. However, because the summary is provided, `FooCmp` is not
compiled within the context of the testing module, but _is_ made available
for `TestFixture` to use, even if it wasn't originally exported from
`FooModule`.

This pattern breaks in Ivy - because summaries are a no-op, this amounts
to a true double declaration of `FooCmp` which raises an error.

Fixing this in user code is possible, but is difficult to do in an
automated or backwards compatible way. An alternative solution is
implemented in this PR.

This PR attempts to capture the user intent of the following previously
unsupported configuration:

```typescript
TestBed.configureTestingModule({
  declarations: [FooCmp, TestFixture],
  imports: [FooModule],
});
```

Note that this is the same as the configuration above in Ivy, as the
`aotSummaries` value provided has no effect.

The user intent here is interpreted as follows:

1) `FooCmp` is a pre-existing component that's being used in the test
   (via import of `FooModule`). It may or may not be exported by this
   module.

2) `FooCmp` should be part of the testing module's scope. That is, it
   should be visible to `TestFixture`. This is because it's listed in
   `declarations`.

This feature effectively makes the `TestBed` testing module special. It's
able to declare components without compiling them, if they're already
compiled (or configured to be compiled) in the imports. And crucially, the
behavior matches the first example with the summary, making Ivy backwards
compatible with View Engine for tests that use summaries.

Kara Erickson a96976e88f fix(core): remove deprecated `TestBed.deprecatedOverrideProvider` API (#30576)
BREAKING CHANGE

In PR #19558, we fixed a bug in `TestBed.overrideProvider` where
eager providers were not being instantiated correctly. However,
it turned out that since this bug had been around for quite a bit,
many apps were relying on the broken behavior where the providers
would not be instantiated. To assist in the transition, the
`TestBed.deprecatedOverrideProvider` method was temporarily
introduced to mimic the old behavior so that apps would have a
longer time period to migrate their code.

2 years and 3 versions later, it is time to remove the temporary
method. This commit removes `TestBed.deprecatedOverrideProvider`
altogether. Any usages of `TestBed.deprecatedOverrideProvider`
should be replaced with `TestBed.overrideProvider`. This may mean
that providers that were not created before will now be instantiated,
which could mean that your tests need to provide more mocks or stubs
for the dependencies of the newly instantiated providers.
