Leading trivia, such as whitespace or comments, is
confusing for developers looking at source-mapped
templates, since they expect the source-map segment
to start after the trivia.
This commit adds skipping trivial characters to the lexer;
and then implements that in the template parser.

This commit also changes the config files and their layout to

Previously, the ServiceWorker registration options should be defined as
an object literal (in order for them to be compatible with Ahead-of-Time
compilation), thus making it impossible to base the ServiceWorker
behavior on runtime conditions.
This commit allows specifying the registration options using a regular
provider, which means that it can take advantage of the `useFactory`
option to determine the config at runtime, while still remaining
compatible with AoT compilation.

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].

The exact messages depend on the timing of several events and may vary
between runs. This occasionally causes flakes on CI.
This commit reduces the risk of flakes by loosen the conditions to only
check for what we actually care about.

Redirects that were updated in 24c61cb63e break the aio_monitoring CircleCI job, since we run the tests against the production angular.io site (that doesn't have the latest redirects config yet).
This change temporary disables the aio_monitoring job to avoid failures for other PRs. The problem will be resolved and the job will be enabled in followup PRs.

Previously, ngtsc included query fields in the list of fields which can
affect the type of a directive via its type constructor. This feature
however has yet to be built, and View Engine in default mode does not
do this inference.
This caused an unexpected bug where private query fields (which should be
an error but are allowed by View Engine) cause the type constructor
signature to be invalid. This commit fixes that issue by disabling the
logic to include query fields.
PR Close#30094
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.

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).

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.
PR Close#30055
This abstract class (and AngularJSUrlCodec) are used for serializing and deserializing pieces of a URL string. AngularJS had a different way of doing this than Angular, and using this class in conjunction with the LocationUpgradeService an application can have control over how AngularJS URLs are serialized and deserialized.

When using the `history` API, setting a new `state` and retrieving it does not pass a `===` test to the object used to set the state. In other words, `history.state` is always a copy. This change makes the `MockPlatformLocation` behave in the same way.
PR Close#30055
This feature adds an `onUrlChange` to Angular's `Location` class. This is useful to track all updates coming from anywhere in the framework. Without this method, it's difficult (or impossible) to track updates run through `location.go()` or `location.replaceState()` as the browser doesn't publish events when `history.pushState()` or `.replaceState()` are run.
PR Close#30055
AngularJS's `$location` service doesn't have a direct counterpart in Angular. This is largely because the `Location` service in Angular was pulled out of the `Router`, but was not purpose-built to stand on its own.
This commit adds a new `@angular/common/upgrade` package with the beginnings of a new `LocationUpgradeService`. This service will more closely match the API of AngularJS and provide a way to replace the `$location` service from AngularJS.
PR Close#30055
Without this change, the framework doesn't surface URL parts such as hostname, protocol, and port. This makes it difficult to rebuild a complete URL. This change provides new APIs to read these values.
PR Close#30055
Previously there wasn't a way to retrieve `history.state` from the `Location` service. The only time the framework exposed this value was in navigation events. This meant if you weren't using the Angular router, there wasn't a way to get access to this `history.state` value other than going directly to the DOM.
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.
This feature will additionally be useful to any application that wants to access state data through Angular rather than going directly to the DOM APIs.
