The term `ReexportStatement` is too general for this particular concept.
Here the re-export actually refers to a wildcard where all the module
exports are being re-exported.
When we introduce other re-export statement types later this will be
confusing.

After the refactoring of the reflection hosts to accommodate
ES2015 classes wrapped in IIFEs. The same treatment needs to
be applied to the rendering formatters.
PR Close#36989
In TS 3.9, ES2015 output can contain ES classes that are wrapped in an
IIFE. So now ES2015 class declarations can look like one of:
```
class OuterClass1 {}
```
```
let OuterClass = class InnerClass {};
```
```
var AliasClass;
let OuterClass = AliasClass = class InnerClass {};
```
```
let OuterClass = (() => class InnerClass {}};
```
```
var AliasClass;
let OuterClass = AliasClass = (() => class InnerClass {})();
```
```
let OuterClass = (() => {
let AdjacentClass = class InnerClass {};
// ... static properties or decorators attached to `AdjacentClass`
return AdjacentClass;
})();
```
```
var AliasClass;
let OuterClass = AliasClass = (() => {
let AdjacentClass = class InnerClass {};
// ... static properties or decorators attached to `AdjacentClass`
return AdjacentClass;
})();
```
The `Esm5ReflectionHost` already handles slightly different IIFE wrappers
around function-based classes. This can be substantially reused when
fixing `Esm2015ReflectionHost`, since there is a lot of commonality
between the two.
This commit moves code from the `Esm5ReflectionHost` into the `Esm2015ReflectionHost`
and looks to share as much as possible between the two hosts.

Previously the path to the unlocker process was being resolved by the
current file-system. In the case that this was a `MockFileSystemWindows`
on a non-Windows operating system, this resulted in an incorrect path
to the entry-point.
Now the path to the entry-point is hand-crafted to avoid being broken by
whatever FileSystem is in use.

The previous implementations of `hasBaseClass()` are almost
identical to the implementation of `getBaseClassExpression()`.
There is little benefit in duplicating this code so this refactoring

ASTs for property read and method calls contain information about
the entire span of the expression, including its receiver. Use cases
like a language service and compile error messages may be more
interested in the span of the direct identifier for which the
expression is constructed (i.e. an accessed property). To support this,
this commit adds a `nameSpan` property on
- `PropertyRead`s
- `SafePropertyRead`s
- `PropertyWrite`s
- `MethodCall`s
- `SafeMethodCall`s
The `nameSpan` property already existed for `BindingPipe`s.
This commit also updates usages of these expressions' `sourceSpan`s in
Ngtsc and the langauge service to use `nameSpan`s where appropriate.

In past versions of the View Engine compiler, we added a warning that is
printed whenever the compiler comes across an Angular declaration with a
constructor that does not match suitable DI tokens. The warning mentioned
that in `v6.x` it will turn into an actual error.
This actually happened as expected for most cases. e.g. the constructor
of `@NgModule`, `@Component`'s, `@Pipe`'s etc will be checked and an error
will be reported if constructor is not DI compatible.
The warning has never been removed though as it was still relevant for
unprovided injectables, or injectables serialized into summaries of the
Angular compiler.
As of version 10, classes that use Angular features need an Angular decorator.
This includes base classes of services that use the lifecycles Angular feature.
Due to this being a common pattern now, we can remove the warning in
View Engine. The warning is not correct, and also quite confusing as it
mentions the planned removal in `v6.x`.

Prior to this commit, number input fields would to fire valueChanges twice: once for `input` events when typing and second for the `change` event when the field lost focus (both events happen at once when using the increment and decrement buttons on the number field).
Fixes#12540
BREAKING CHANGE: Number inputs no longer listen to the `change` event.
* Tests which trigger `change` events need to be updated to trigger `input` events instead.
* The `change` event was in place to support IE9, as we found that `input` events were not fired with backspace or cut actions. If you need to maintain IE9 support, you will need to add a change event listener to number inputs and call the `onChange` method of `NumberValueAccessor` manually.
* Lastly, old versions of WebDriver would synthetically trigger the `change` event on `WebElement.clear` and `WebElement.sendKeys`. If you are using an old version of WebDriver, you may need to update tests to ensure `input` events are triggered. For example, you could use `element.sendKeys(Keys.chord(Keys.CONTROL, "a"), Keys.BACK_SPACE);` in place of `element.clear()`.

Enables the `ng update` migrations for v10. Status for individual
migrations:
**undecorated-classes-with-di**.
This migration dealt exlusively with inherited constructors and
cases where a derived component was undecorated. In those cases,
the migration added `@Directive()` or copied the inherited decorator
to the derived class.
We don't need to run this migration again because ngtsc throws if
constructor is inherited from an undecorated class. Also ngtsc will
throw if a NgModule references an undecorated class in the declarations.
***undecorated-classes-with-decorated-fields***
This migration exclusively deals with undecorated classes that use
Angular features but are not decorated. Angular features include
the use of lifecycle hooks or class fields with Angular decorators,
such as `@Input()`.
We want to re-run this migration in v10 as we will disable the
compatibility code in ngtsc that detects such undecorated classes
as `@Directive`.
**module-with-providers**:
This migration adds an explicit generic type to `ModuleWithProviders`.
As of v10, the generic type is required, so we need to re-run the
migration again.
**renderer-to-renderer2**:
We don't need to re-run that migration again as the
renderer has been already removed in v9.
**missing-injectable**:
This migration is exclusively concerned with undecorated
providers referenced in an `NgModule`. We should re-run
that migration again as we don't have proper backsliding
prevention for this yet. We can consider adding an error
in ngtsc for v10, or v11. In either way, we should re-run
the migration.
**dynamic-queries**:
We ran this one in v9 to reduce code complexity in projects. Instead
of explicitly passing `static: false`, not passing any object literal
has the same semantics. We don't need to re-run the migration again
since there is no good way to prevent backsliding and we cannot always
run this migration for future versions (as some apps might actually
intentionally use the explicit `static: false` option).
PR Close#36921
Previously in v9, we deprecated the pattern of undecorated base classes
that rely on Angular features. We ran a migration for this in version 9
and will run the same on in version 10 again.
To ensure that projects do not regress and start using the unsupported
pattern again, we report an error in ngtsc if such undecorated classes
are discovered.
We keep the compatibility code enabled in ngcc so that libraries
can be still be consumed, even if they have not been migrated yet.
Resolves FW-2130.
PR Close#36921
As of v10, undecorated classes using Angular features are no longer
supported. In v10, we plan on removing the undecorated classes
compatibility code in ngtsc. This means that old patterns for
undecorated classes will result in compilation errors.
We had a migration for this in v9 already, but it looks like
the migration does not handle cases where classes uses lifecycle
hooks. This is handled in the ngtsc compatibility code, and we
should handle it similarly in migrations too.
This has not been outlined in the migration plan initially,
but an appendix has been added for v10 to the plan document.
https://hackmd.io/vuQfavzfRG6KUCtU7oK_EA?both.
Note: The migration is unable to determine whether a given undecorated
class that only defines `ngOnDestroy` is a directive or an actual
service. This means that in some cases the migration cannot do
more than adding a TODO and printing an failure.
Certainly there are more ways to determine the type of such classes,
but it would involve metadata and NgModule analysis. This is out of
scope for this migration.
