With #30058, the ngUpgrade internal `angular.module()` method was
renamed to `angular.module_()` (to avoid a webpack bug).
Merging #29794 afterwards resulted in some broken tests, because it
still used the old `angular.module()` method name. (The PR had been
tested on CI against a revision that did not contain the rename.)
This commit fixes the broken tests by renaming the remaining occurrences
of `angular.module()`.

Previously, under certain circumstances, `NgZone#onMicrotaskEmpty` could
emit while a `$digest` was in progress, thus triggering another
`$digest`, which in turn would throw a `$digest already in progress`
error. Furthermore, throwing an error from inside the `onMicrotaskEmpty`
subscription would result in unsubscribing and stop triggering further
`$digest`s, when `onMicrotaskEmpty` emitted.
Usually, emitting while a `$digest` was already in progress was a result
of unintentionally running some part of AngularJS outside the Angular
zone, but there are valid (if rare) usecases where this can happen
(see #24680 for details).
This commit addresses the issue as follows:
- If a `$digest` is in progress when `onMicrotaskEmpty` emits, do not
trigger another `$digest` (to avoid the error). `$evalAsync()` is used
instead, to ensure that the bindings are evaluated at least once more.
- Since there is still a high probability that the situation is a result
of programming error (i.e. some AngularJS part running outside the
Angular Zone), a warning will be logged, but only if the app is in
[dev mode][1].

When targeting ES2015 (as is the default in cli@8), `const` is not
downleveled to `var` and thus declaring `const module` throws an error
due to webpack wrapping the code in a function call with a `module`
argument (even when compiling for the `web` environment).

Previously we had to share code between upgrade/dynamic and upgrade/static
by symlinking the `src` folder, which allowed both packages to access
the upgrade/common files.
These symlinks are always problematic on Windows, where we had to run
a script to re-link them, and restore them.
This change uses Bazel packages to share the `upgrade/common` code,
which avoids the need for symlinking the `src` folder.
Also, the Windows specific scripts that fixup the symlinks have also
been removed as there is no more need for them.

At the moment, the API extractor doesn't support local namespaced imports, this will break the generation of flat dts files. When we turn on dts bundling for this package it will break. Hence this is the ground work needed for making this package compatable with the API extractor.

In ngUpgrade (dynamic) we create a dynamic Angular `Directive` that wraps AngularJS components
that are being upgraded. The constructor of this `Directive` class returns a different instance
than `this`. It is this instance that actually contains the life-cycle hook handlers.
This would break in ivy, since the methods on the prototype of the original class are wired up,
rather than the instance methods. This results in hooks like `ngOnInit` not being called.
This commit refactors the code to extend the inner class that was being returned so that the
prototype chain is correct for both ViewEngine and ivy.
This change resolves a number of failing ivy tests, but also exposes other failures that were
masked by this issue. The tests have been updated accordingly.

The way that `UpgradeAdapter` needs to be setup, you often find that
you must pass a `forwardRef` for an `NgModule.import`. Pre-ivy, this
gets resolved at runtime, but until this is implemented in ivy, we can
workaround it by resolving it in the `UpgradeAdapter` upfront.
This should be backward-compatible since by the time we actually
create the dynamic `NgModule` that has the import, the imported
class should be defined.

All errors for existing fields have been detected and suppressed with a

Issue/24571 is tracking proper clean up of those instances.
One-line change required in ivy/compilation.ts, because it appears that

Previously, when a downgraded component was destroyed in a way that did
not trigger the `$destroy` event on the element (e.g. when a parent
element was removed from the DOM by Angular, not AngularJS), the
`ComponentRef` was not destroyed and unregistered.
This commit fixes it by listening for the `$destroy` event on both the
element and the scope.

Previously, having a `=` binding on an upgraded components would result
in setting the corresponding property to an EventEmitter function. This
should only happen for `&` bindings.
This commit rstrores the correct behavior.
Note:
The issue was only present in the dynamic version of `ngUpgrade`. The
static version worked as expected.
The error did not show up in tests, because in AngularJS v1.5.x a
function would be serialized to an empty string in interpolations, thus
making them indistinguishable from uninitialized properties (in the
view). The serialization behavior changed in AngularJS v1.6.x, making
the errors visible.

It doesn't make any difference in this case, because the we only check the
property for truthfulness (and being undefined has the same effect as being set
to false).

BREAKING CHANGE
It is no longer possible to declare classes in this format.
```
Component({...}).
Class({
constructor: function() {...}
})
```
This format would only work with JIT and with ES5. This mode doesn’t
allow build tools like Webpack to process and optimize the code, which
results in prohibitively large bundles. We are removing this API
because we are trying to ensure that everyone is on the fast path by
default, and it is not possible to get on the fast path using the ES5
DSL. The replacement is to use TypeScript and `@Decorator` format.
```
@Component({...})
class {
constructor() {...}
}
```
This change allows ReflectiveInjector to be tree shaken resulting
in not needed Reflect polyfil and smaller bundles.
Code savings for HelloWorld using Closure:
Reflective: bundle.js: 105,864(34,190 gzip)
Static: bundle.js: 154,889(33,555 gzip)
645( 2%)
BREAKING CHANGE:
`platformXXXX()` no longer accepts providers which depend on reflection.
Specifically the method signature when from `Provider[]` to
`StaticProvider[]`.
Example:
Before:
```
[
MyClass,
{provide: ClassA, useClass: SubClassA}
]
```
After:
```
[
{provide: MyClass, deps: [Dep1,...]},
{provide: ClassA, useClass: SubClassA, deps: [Dep1,...]}
]
```
NOTE: This only applies to platform creation and providers for the JIT
compiler. It does not apply to `@Compotent` or `@NgModule` provides
declarations.
Benchpress note: Previously Benchpress also supported reflective
provides, which now require static providers.
DEPRECATION:
- `ReflectiveInjector` is now deprecated as it will be remove. Use
`Injector.create` as a replacement.

(#17971)
This commit changes the dynamic version of ngUpgrade to use `UpgradeHelper`,
thus bringing its behavior (wrt upgraded components) much closer to
`upgrade/static`. Fixes/features include:
- Fix template compilation: Now takes place in the correct DOM context, instead
of in a detached node (thus has access to required ancestors etc).
- Fix support for the `$onInit()` lifecycle hook.
- Fix single-slot transclusion (including optional transclusion and fallback
content).
- Add support for multi-slot transclusion (inclusing optional slots and fallback
content).
- Add support for binding required controllers to the directive's controller
(and make the `require` behavior more consistent with AngularJS).
- Add support for pre-/post-linking functions.
(This also ports the fixes from #16627 to the dynamic version.)
Fixes#11044
Previously, non-bracketed inputs (e.g. `xyz="foo"`) on downgraded components
were initialized using `attrs.$observe()` (which uses `$evalAsync()` under the
hood), while bracketed inputs (e.g. `[xyz]="'foo'"`) were initialized using
`$watch()`. If the downgraded component was created during a `$digest` (e.g. by
an `ng-if` watcher), the non-bracketed inputs were not initialized in time for
the initial call to `ngOnChanges()` and `ngOnInit()`.
This commit fixes it by using `$watch()` to initialize all inputs. `$observe()`
is still used for subsequent updates on non-bracketed inputs, because it is more
performant.
Fixes#16212
Previously, when using a different property/attribute name for an upgraded
component's binding (e.g. `bindings: {propName: '<attrName'}`), the property and
attribute names were swapped (e.g. using `attrName` as the property name and
`propName` as the attribute name). This resulted in unexpected behavior.
This commit fixes this using the correct names for properties and attributes.
This only affects `upgrade/dynamic`. `upgrade/static` works correctly already.
