There was a problem with a combination of the `eager` URL update, browser `back` button, and hybrid applications. Details provided in internal ticket http://b/123667227.
This fix handles the problem by setting `router.browserUrlTree` when all conditions have failed, meaning the browser doesn't do anything with the navigation other than update internal data structures. Without this change, the problem was an old value was stored in `router.broserUrlTree` causing some new navigations to be compared to an old value and breaking future navigations.

In the existing implementation the `elementPropertyInternal` function (meant to
set element properties) was executed even if a bound value didn't change. The
`elementPropertyInternal` was inspecting the incoming value and after comparing it
to `NO_CHANGE` - exiting early. All in all it meant that we were unnecessarily
invoking the `elementPropertyInternal` function for cases where bound value didn't
change.
Based on my bencharks (running change detection without any model update in a tight
loop) this unnecessary function call was causing ~5% slowdown in the change detection
process.

Packages that do not follow APF may have the declaration files in the same
directory as one source format, typically ES5. This is problematic for ngcc,
as it needs to create a TypeScript program with all JavaScript sources of
an entry-point, whereas TypeScript's module resolution mechanism would have
resolved an internal module import to the external facing .d.ts declaration
file, instead of the JavaScript source file. This behavior results in the
program to be analysed being incomplete.
This commit introduces a custom compiler host that recognizes the above
scenario and rewires the resolution of a .d.ts declaration file to its
JavaScript counterpart, if applicable.

Currently the `static-query` migrations fails at the final step of
updating a query when the query already specifies options which
cannot be transformed easily. e.g. the options are computed through
a function call: `@ViewChild(..., getQueryOpts());` or `@ViewChild(..., myOptionsVar)`.
In these cases we technically could add additionally logic to update
the query options, but given that this is an edge-case and it's
potentially over-engineering the migration schematic, we just
always add a TODO for the timing and print out the determined
query timing in the console. The developer in that case just needs
to manually update the logic for the query options to contain the
printed query timing.

PR Close#29643
When working out the dependencies between entry-points
ngcc must parse the import statements and then resolve the
import path to the actual file. This is complicated because module
resolution is not trivial.
Previously ngcc used the node.js `require.resolve`, with some
hacking to resolve modules. This change refactors the `DependencyHost`
to use a new custom `ModuleResolver`, which is optimized for this use
case.
Moreover, because we are in full control of the resolution,
we can support TS `paths` aliases, where not all imports come from
`node_modules`. This is the case in some CLI projects where there are
compiled libraries that are stored locally in a `dist` folder.

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].

affect the type of a directive via its type constructor. This feature

ngtsc generates type constructors which infer the type of a directive based
on its inputs. Previously, a bug existed where this inference would fail in
the case of 'any' input values. For example, the inference of NgForOf fails
when an 'any' is provided, as it causes TypeScript to attempt to solve:
T[] = any
In this case, T gets inferred as {}, the empty object type, which is not
desirable.
The fix is to assign generic types in type constructors a default type of
'any', which TypeScript uses instead of {} when inference fails.

The proposed ES dynamic import() is now supported by the Angular CLI and the
larger toolchain. This renders the `loadChildren: string` API largely
redundant, as import() is far more natural, is less error-prone, and is
standards compliant. This commit deprecates the `string` form of
`loadChildren` in favor of dynamic import().
DEPRECATION:
When defining lazy-loaded route, Angular previously offered two options for
configuring the module to be loaded, both via the `loadChildren` parameter
of the route. Most Angular developers are familiar withthe `string` form of
this API. For example, the following route definition configures Angular to
load a `LazyModule` NgModule from `lazy-route/lazy.module.ts`:
```
[{
path: 'lazy',
loadChildren: 'lazy-route/lazy.module#LazyModule',
}]
```
This "magic string" configuration was previously necessary as there was
no dynamic module loading standard on the web. This has changed with the
pending standardization of dynamic `import()` expressions, which are now
supported in the Angular CLI and in web tooling in general. `import()`
offers a more natural and robust solution to dynamic module loading. The
above example can be rewritten to use dynamic `import()`:
```
[{
path: 'lazy',
loadChildren: () => import('./lazy-route/lazy.module').then(mod => mod.LazyModule),
}]
```
This form of lazy loading offers significant advantages in terms of:
* type checking via TypeScript
* simplicity of generated code
* future potential to run natively in supporting browsers
(see: [caniuse: dynamic import()](https://caniuse.com/#feat=es6-module-dynamic-import))
As a result, Angular is deprecating the `loadChildren: string` syntax in
favor of ES dynamic `import()`. An automatic migration will run during
`ng upgrade` to convert your existing Angular code to the new syntax.

This commit provides a replacement for `$location`. The new service is written in Angular, and can be consumed into existing applications by using the downgraded version
of the provider.
Prior to this addition, applications upgrading from AngularJS to Angular could get into a situation where AngularJS wanted to control the URL, and would often parse or se
rialize the URL in a different way than Angular. Additionally, AngularJS was alerted to URL changes only through the `$digest` cycle. This provided a buggy feedback loop
from Angular to AngularJS.
With this new `LocationUpgradeProvider`, the `$location` methods and events are provided in Angular, and use Angular APIs to make updates to the URL. Additionally, change
s to the URL made by other parts of the Angular framework (such as the Router) will be listened for and will cause events to fire in AngularJS, but will no longer attempt
to update the URL (since it was already updated by the Angular framework).
This centralizes URL reads and writes to Angular and should help provide an easier path to upgrading AngularJS applications to Angular.

This abstract class (and AngularJSUrlCodec) are used for serializing and deserializing pieces of a URL string.

This feature adds an `onUrlChange` to Angular's `Location` class. This is useful to track all updates coming from anywhere in the framework.

This PR adds an API to retrieve the value of `history.state`. This will be useful and needed to provide a backwards-compatible `Location` service that can emulate AngularJS's `$location` service since we will need to be able to read the state data in order to produce AngularJS location transition events.

ngtsc previously could attempt to reuse the main ts.Program twice. This
occurred when template type-checking was enabled and then an incremental
build was performed. This breaks a TypeScript invariant - ts.Programs can
only be reused once.
The creation of the template type-checking program reuses the main program,
rendering it moot. Then, on the next incremental build the main program
would be subject to reuse again, which would crash inside TypeScript.
This commit fixes the issue by reusing the template type-checking program
from the previous run on the next incremental build. Since under normal
circumstances the files in the type-checking program aren't changed, this
should be just as fast.
Testing strategy: a test is added in the incremental_spec which validates
that program reuse with type-checking turned on does not crash the compiler.

The compiler uses metadata to represent what it statically knows about
various expressions in a program. Occasionally, expressions in the program
for which metadata is extracted may contain sub-expressions which are not
representable in metadata. One such construct is an arrow function.
The compiler does not always need to understand such expressions completely.
For example, for a provider defined with `useValue`, the compiler does not
need to understand the value at all, only the outer provider definition. In
this case, the compiler employs a technique known as "expression lowering",
where it rewrites the provider expression into one that can be represented
in metadata. Chiefly, this involves extracting out the dynamic part (the
`useValue` expression) into an exported constant.
Lowering is applied through a heuristic, which considers the containing
statement as well as the field name of the expression.
Previously, this heuristic was not completely accurate in the case of
route definitions and the `loadChildren` field, which is lowered. If the
route definition using `loadChildren` existed inside a decorator invocation,
lowering was performed correctly. However, if it existed inside a standalone
variable declaration with an export keyword, the heuristic would conclude
that lowering was unnecessary. For ordinary providers this is true; however
the compiler attempts to fully understand the ROUTES token and thus even if
an array of routes is declared in an exported variable, any `loadChildren`
expressions within still need to be lowered.
This commit enables lowering of already exported variables under a limited
set of conditions (where the initializer expression is of a specific form).
This should enable the use of `loadChildren` in route definitions.
