We recently added a transformer to NGC that is responsible for downleveling Angular
decorators and constructor parameter types. The primary goal was to mitigate a
TypeScript limitation/issue that surfaces in Angular projects due to the heavy
reliance on type metadata being captured for DI. Additionally this is a pre-requisite
of making `tsickle` optional in the Angular bazel toolchain.
See: 401ef71ae5 for more context on this.
Another (less important) goal was to make sure that the CLI can re-use
this transformer for its JIT mode compilation. The CLI (as outlined in
the commit mentioned above), already has a transformer for downleveling
constructor parameters. We want to avoid this duplication and exported
the transform through the tooling-private compiler entry-point.
Early experiments in using this transformer over the current one, highlighted
that in JIT, class decorators cannot be downleveled. Angular relies on those
to be invoked immediately for JIT (so that factories etc. are generated upon loading)
The transformer we exposed, always downlevels such class decorators
though, so that would break CLI's JIT mode. We can address the CLI's
needs by adding another flag to skip class decorators. This will allow
us to continue with the goal of de-duplication.

Commit 24b2f1da2b introduced an `NgCompiler` which operates on a
`ts.Program` independently of the `NgtscProgram`. The NgCompiler got its
`IncrementalDriver` (for incremental reuse of Angular compilation results)
by looking at a monkey-patched property on the `ts.Program`.
This monkey-patching operation causes problems with the Angular indexer
(specifically, it seems to cause the indexer to retain too much of prior
programs, resulting in OOM issues). To work around this, `IncrementalDriver`
reuse is now handled by a dedicated `IncrementalBuildStrategy`. One
implementation of this interface is used by the `NgtscProgram` to perform
the old-style reuse, relying on the previous instance of `NgtscProgram`
instead of monkey-patching. Only for `NgTscPlugin` is the monkey-patching
strategy used, as the plugin sits behind an interface which only provides
access to the `ts.Program`, not a prior instance of the plugin.

This PR changes the logic for determining when to skip route processing from
using the URL of the last attempted navigation to the actual resulting URL after

Because guards may prevent navigation and reset the browser URL, the raw

browser at the end of the navigation process. For that reason, we need to use
`urlAfterRedirects` instead.

Previously, ngcc would only be able to match an ngcc configuration to
packages that were located inside the project's top-level
`node_modules/`. However, if there are multiple versions of a package in
a project (e.g. as a transitive dependency of other packages), multiple
copies of a package (at different versions) may exist in nested
`node_modules/` directories. For example, one at
`<project-root>/node_modules/some-package/` and one at
`<project-root>/node_modules/other-package/node_modules/some-package/`.
In such cases, ngcc was only able to detect the config for the first
copy but not for the second.
This commit fixes this by returning a new instance of
`ProcessedNgccPackageConfig` for each different package path (even if
they refer to the same package name). In these
`ProcessedNgccPackageConfig`, the `entryPoints` paths have been
processed to take the package path into account.

This commit adds a `packageName` property to the `EntryPoint` interface.

PR Close#37040
In order to retrieve the ngcc configuration (if any) for an entry-point,
ngcc has to detect the containing package's version.
Previously, ngcc would try to read the version from the entry-point's
`package.json` file, which was different than the package's top-level
`package.json` for secondary entry-points. For example, it would try to
read it from `node_modules/@angular/common/http/package.json` for
entry-point `@angular/common/http`. However, the `package.json` files
for secondary entry-points are not guaranteed to include a `version`
property.
This commit fixes this by first trying to read the version from the
_package's_ `package.json` (falling back to the entry-point's
`package.json`). For example, it will first try to read it from
`@angular/common/package.json` for entry-point `@angular/common/http`.

Rename the `package` property to `packagePath` on the `EntryPoint`

`packageName` property that will be added in a subsequent commit.
This commit also re-orders the `EntryPoint` properties to group related
properties together and to match the order of properties on instances
with that on the interface.
PR Close#37040
Previously, when an entry-point was ignored via an ngcc config, ngcc
would scan sub-directories for sub-entry-points, but would not use the
correct `packagePath`. For example, if `@angular/common` was ignored, it
would look at `@angular/common/http` but incorrectly use
`.../@angular/common/http` as the `packagePath` (instead of
`.../@angular/common`). As a result, it would not retrieve the correct
ngcc config for the actual package.
This commit fixes it by ensuring the correct `packagePath` is used, even
if the primary entry-point corresponding to that path is ignored. In
order to do this, a new return value for `getEntryPointInfo()` is added:
`IGNORED_ENTRY_POINT`. This is used to differentiate between directories
that correspond to no or an incompatible entry-point and those that
correspond to an entry-point that could otherwise be valid but is
explicitly ignored. Consumers of `getEntryPointInfo()` can then use this
info to discard ignored entry-points, but still use the correct
`packagePath` when scanning their sub-directories for secondary
entry-points.

In the early Zone.js versions (< 0.10.3), `ZoneAwarePromise` did not support `Symbol.species`,
so when user used a 3rd party `Promise` such as `es6-promise`, and try to load the promise library after import of `zone.js`, the loading promise library will overwrite the patched `Promise` from `zone.js` and will break `Promise` semantics with respect to `zone.js`.
Starting with `zone.js` 0.10.3, `Symbol.species` is supported therefore this will not longer be an issue. (https://github.com//pull/34533)
Before 0.10.3, the logic in zone.js tried to handle the case in the wrong way. It did so by overriding the descriptor of `global.Promise`, to allow the 3rd party libraries to override native `Promise` instead of `ZoneAwarePromise`. This is not the correct solution, and since the `Promise.species` is now supported, the 3rd party solution of overriding `global.Promise` is no longer needed.
PR removes the wrong work around logic. (This will improve the bundle size.)

This is a known issue of zone.js,

log += 'click;';
});
button.click();
expect(log).toEqual('click;microtask;');

});
```
Since in this case, we use native `setTimeout` which is not a ZoneTask,
so zone.js consider the button click handler as the top Task then drain the
microTaskQueue after the click at once, which is not correct(too early).
This case was an edge case and not reported by the users, until we have the
new option ngZoneEventCoalescing, since the event coalescing will happen
in native requestAnimationFrame, so it will not be a ZoneTask, and zone.js will
consider any Task happen in the change detection stage as the top task, and if
there are any microTasks(such as Promise.then) happen in the process, it may be
drained earlier than it should be, so to prevent this situation, we need to schedule
a fake event task and run the change detection check in this fake event task,
so the Task happen in the change detection stage will not be
considered as top ZoneTask.

It is quite common for the TS compiler to have to add synthetic
types to function signatures, where the developer has not
explicitly provided them. This results in `import(...)` expressions
appearing in typings files. For example in `@ngrx/data` there is a
class with a getter that has an implicit type:
```ts
export declare class EntityCollectionServiceBase<...> {
...
get store() {
return this.dispatcher.store;
}
...
}
```
In the d.ts file for this we get:
```ts
get store(): Store<import("@ngrx/data").EntityCache>;
```
Given that this file is within the `@ngrx/data` package already,
this caused ngcc to believe that there was a circular dependency,
causing it to fail to process the package - and in fact crash!
This commit resolves this problem by ignoring `import()` expressions
when scanning typings programs for dependencies. This ability was
only introduced very recently in a 10.0.0 RC release, and so it has
limited benefit given that up till now ngcc has been able to process
libraries effectively without it. Moreover, in the rare case that a
package does have such a dependency, it should get picked up
by the sync ngcc+CLI integration point.

In v7 of Angular we removed `tsickle` from the default `ngc` pipeline.
This had the negative potential of breaking ES2015 output and SSR due
to a limitation in TypeScript.
TypeScript by default preserves type information for decorated constructor
parameters when `emitDecoratorMetadata` is enabled. For example,
consider this snippet below:
```
@Directive()
export class MyDirective {
constructor(button: MyButton) {}
}
export class MyButton {}
```
TypeScript would generate metadata for the `MyDirective` class it has
a decorator applied. This metadata would be needed in JIT mode, or
for libraries that provide `MyDirective` through NPM. The metadata would
look as followed:
```
let MyDirective = class MyDir {}
MyDirective = __decorate([
Directive(),
__metadata("design:paramtypes", [MyButton]),
], MyDirective);
let MyButton = class MyButton {}
```
Notice that TypeScript generated calls to `__decorate` and
`__metadata`. These calls are needed so that the Angular compiler
is able to determine whether `MyDirective` is actually an directive,
and what types are needed for dependency injection.
The limitation surfaces in this concrete example because `MyButton`
is declared after the `__metadata(..)` call, while `__metadata`
actually directly references `MyButton`. This is illegal though because
`MyButton` has not been declared at this point. This is due to the
so-called temporal dead zone in JavaScript. Errors like followed will
be reported at runtime when such file/code evaluates:
```
Uncaught ReferenceError: Cannot access 'MyButton' before initialization
```
As noted, this is a TypeScript limitation because ideally TypeScript
shouldn't evaluate `__metadata`/reference `MyButton` immediately.
Instead, it should defer the reference until `MyButton` is actually
declared. This limitation will not be fixed by the TypeScript team
though because it's a limitation as per current design and they will
only revisit this once the tc39 decorator proposal is finalized
(currently stage-2 at time of writing).
Given this wontfix on the TypeScript side, and our heavy reliance on
this metadata in libraries (and for JIT mode), we intend to fix this
from within the Angular compiler by downleveling decorators to static
properties that don't need to evaluate directly. For example:
```
MyDirective.ctorParameters = () => [MyButton];
```
With this snippet above, `MyButton` is not referenced directly. Only
lazily when the Angular runtime needs it. This mitigates the temporal
dead zone issue caused by a limitation in TypeScript's decorator
metadata output. See: https://github.com/microsoft/TypeScript/issues/27519.
In the past (as noted; before version 7), the Angular compiler by
default used tsickle that already performed this transformation. We
moved the transformation to the CLI for JIT and `ng-packager`, but now
we realize that we can move this all to a single place in the compiler
so that standalone ngc consumers can benefit too, and that we can
disable tsickle in our Bazel `ngc-wrapped` pipeline (that currently
still relies on tsickle to perform this decorator processing).
This transformation also has another positive side-effect of making
Angular application/library code more compatible with server-side
rendering. In principle, TypeScript would also preserve type information
for decorated class members (similar to how it did that for constructor
parameters) at runtime. This becomes an issue when your application
relies on native DOM globals for decorated class member types. e.g.
```
@Input() panelElement: HTMLElement;
```
Your application code would then reference `HTMLElement` directly
whenever the source file is loaded in NodeJS for SSR. `HTMLElement`
does not exist on the server though, so that will become an invalid
reference. One could work around this by providing global mocks for
these DOM symbols, but that doesn't match up with other places where
dependency injection is used for mocking DOM/browser specific symbols.
More context in this issue: #30586. The TL;DR here is that the Angular
compiler does not care about types for these class members, so it won't
ever reference `HTMLElement` at runtime.

putting a directive with host binding on an `ng-template` or `ng-container` is most often a mistake.
Developers should be made aware that the host binding will have no effect in these cases.

pushing new updates on the server).
More specifically, if control doc `/latest` of `ngsw:/:db:control` once
gets a bad value, then the service worker will fail early, and won't be
able to overwrite `/latest` with new, valid values (the ones from future
updates).
For example, once in this state, URL `/ngsw/state` will show:
NGSW Debug Info:
Driver state: EXISTING_CLIENTS_ONLY (Degraded due to failed initialization: Invariant violated (initialize): latest hash 8b75… has no known manifest
Error: Invariant violated (initialize): latest hash 8b75… has no known manifest
at Driver.<anonymous> (https://my.app/ngsw-worker.js:2302:27)
at Generator.next (<anonymous>)
at fulfilled (https://my.app/ngsw-worker.js:175:62))
Latest manifest hash: 8b75…
Last update check: 22s971u
... with hash `8b75…` corresponding to no installed version.
**Solution**
Currently, when such a case happens, the service worker [simply fails
with an assertion][1]. Because this failure happens early, and is not
handled, the service worker is not able to update `/latest` to new
installed app versions.
I propose to detect this corrupted case (a `latest` hash that doesn't
match any installed version) a few lines above, so that the service
worker can correctly call its [already existing cleaning code][2].

Previously, event listeners for component output events attached on an
Angular custom element before inserting it into the DOM (i.e. before
instantiating the underlying component) didn't fire for events emitted
during initialization lifecycle hooks, such as `ngAfterContentInit`,
`ngAfterViewInit`, `ngOnChanges` (initial call) and `ngOnInit`.
The reason was that that `NgElementImpl` [subscribed to events][1]
_after_ calling [ngElementStrategy#connect()][2], which is where the
[initial change detection][3] takes place (running the initialization
lifecycle hooks).
This commit fixes this by:
1. Ensuring `ComponentNgElementStrategy#events` is defined and available
for subscribing to, even before instantiating the component.
2. Ensuring `NgElementImpl` subscribes to `NgElementStrategy#events`
before calling `NgElementStrategy#connect()` (which initializes the
component instance).

The angular.io production deployment script (`deploy-to-firebase.sh`)
compares the major version corresponding to the current branch (e.g.
`8` for branch `8.1.x`) against the major stable version (e.g. `9` if
the current stable version is `9.1.0`). It then uses the result of that
comparison to determine whether the current branch corresponds to a
newer version than stable (i.e. an RC version) and thus should not be
deployed or to an older version and thus may need to be deployed to an
archive vX.angular.io project.
Previously, the script was using string comparison (`<`) to compare the
two major versions. This could produce incorrect results for an RC major
version that is numerically greater than the stable but
lexicographically smaller. For example, 10 vs 9 (10 is numerically
greater but lexicographically smaller than 9).

`NgCompiler` is the heart of ngtsc and can be used to analyze and compile
Angular programs in a variety of environments. Most of these integrations
rely on `NgProgram` and the creation of an `NgCompilerHost` in order to
create a `ts.Program` with the right shape for `NgCompiler`.
However, certain environments (such as the Angular Language Service) have
their own mechanisms for creating `ts.Program`s that don't make use of a
`ts.CompilerHost`. In such environments, an `NgCompilerHost` does not make
sense.
This commit breaks the dependency of `NgCompiler` on `NgCompilerHost` and
extracts the specific interface of the host on which `NgCompiler` depends
into a new interface, `NgCompilerAdapter`. This interface includes methods
from `ts.CompilerHost`, the `ExtendedTsCompilerHost`, as well as APIs from
`NgCompilerHost`.
A consumer such as the language service can implement this API without
needing to jump through hoops to create an `NgCompilerHost` implementation
that somehow wraps its specific environment.

When the compiler encounters a function call within an NgModule imports
section, it attempts to resolve it to an NgModule-annotated class by
looking at the function body and evaluating the statements there. This
evaluation can only understand simple functions which have a single
return statement as their body. If the function the user writes is more
complex than that, the compiler won't be able to understand it and
previously the PartialEvaluator would return a "DynamicValue" for
that import.
With this change, in the event the function body resolution fails the
PartialEvaluator will now attempt to use its foreign function resolvers to
determine the correct result from the function's type signtaure instead. If
the function is annotated with a correct ModuleWithProviders type, the
compiler will be able to understand the import without static analysis of
the function body.

If we detect that an injectable class is inheriting from another injectable, we generate code that looks something like this:
```
const baseFactory = ɵɵgetInheritedFactory(Child);
@Injectable()
class Parent {}
@Injectable()
class Child extends Parent {
static ɵfac = (t) => baseFactory(t || Child)
}
```
This usually works fine, because the `ɵɵgetInheritedFactory` resolves to the factory of `Parent`, but the logic can break down if the `Child` class has a custom decorator. Custom decorators can return a new class that extends the original once, which means that the `ɵɵgetInheritedFactory` call will now resolve to the factory of the `Child`, causing an infinite loop.
These changes fix the issue by changing the inherited factory resolution logic so that it walks up the prototype chain class-by-class, while skipping classes that have the same factory as the class that was passed in.

of headaches for some time for Angular packages, we are removing it for
now while we rethink our
strategy to make Angular Closure compatible outside of Google.
This change has no effect on our Closure compatibility within Google

BREAKING CHANGE: Angular npm packages no longer contain jsdoc comments
to support Closure Compiler's advanced optimizations
The support for Closure compiler in Angular packages has been
experimental and broken for quite some
time.
As of TS3.9 Closure is unusable with the JavaScript emit. Please follow
https://github.com/microsoft/TypeScript/issues/38374 for more
information and updates.
If you used Closure compiler with Angular in the past, you will likely
be better off consuming
Angular packages built from sources directly rather than consuming the
version we publish on npm
which is primarily optimized for Webpack/Rollup + Terser build pipeline.
As a temporary workaround you might consider using your current build
pipeline with Closure flag
`--compilation_level=SIMPLE`. This flag will ensure that your build
pipeline produces buildable and
runnable artifacts, at the cost of increased payload size due to
advanced optimizations being disabled.

needs by leaving a comment on https://github.com/angular/angular/issues/37234.

Previously, the correct behavior of Angular custom elements relied on
the constructor being called (and thus the `injector` property being

do not call the constructor of custom elements, which resulted in the
`injector` property being undefined and the `NgElementStrategy` failing

This commit fixes it by being tolerant to the `injector` property being
undefined and falling back to the injector passed to the
`createCustomElement()` config.

`ts-node` is now an optional peer dependency of the shared dev-infra
package. Whenever a `ng-dev` command runs, and a TypeScript-based
configuration file exists, `ts-node` is set up if available.
That allows consumers of the package (as the components repo) to more
conveniently use a TypeScript-based configuration for dev-infra.
Currently, commands would need to be proxied through `ts-node`
which rather complicates the setup:
```
NG_DEV_COMMAND="ts-node ./node_modules/@angular/dev-infra-private/cli.js"

As mentioned in the previous commit, the autosquash strategy has
not been used in the components repo, so we could easily regress.
After thorough manual testing of the autosquash strategy again,
now that the merge script will be moved to framework, it came
to mind that there is a bug with the base revision in the
autosquash merge strategy. The problem is that the base revision
of a given PR is relying on the amount of commits in a PR.
This is prone to error because the amount of commits could easily
change in the autosquash merge strategy, because fixup or squash
commits will be collapsed. Basically invalidating the base revision.
To fix this, we fixate the base revision by determining the actual
SHA. This one is guaranteed to not change after the autosquash rebase.
The current merge script in framework fixates the revision by creating
a separate branch, but there is no benefit in that, compared to just
using an explicit SHA that doesn't need to be cleaned up..
PR Close#37138
The components repo does not use the autosquash merge strategy, so
recent changes to that seem to broke the autosquash strategy.
Since we don't run the rebase in interactive mode, the `--autosquash`
flag has no effect. This is by design in Git. We can make it work by
setting the git sequence editor to `true` so that the rebase seems
like an interactive one to Git, while it isn't one for the user.
This matches conceptually with the merge script currently used in
framework. The only difference is that we allow a real interactive
rebase if the `commit message fixup` label is applied. This allows
commit message modifications (and others) if needed.

The work to support case-sensitivity in the `FileSystem` went too far
with the `LogicalFileSystem`, which is used to compute import paths
that will be added to files processed by ngtsc and ngcc.
Previously all logical paths were canonicalised, which meant that on
case-insensitive file-systems, the paths were all set to lower case.
This resulted in incorrect imports being added to files. For example:
```
import { Apollo } from './Apollo';
import { SelectPipe } from './SelectPipe';
import * as ɵngcc0 from '@angular/core';
import * as ɵngcc1 from './selectpipe';
```
The import from `./SelectPipe` is from the original file, while the
import from `./selectpipe` is added by ngcc. This causes the
TypeScript compiler to complain, or worse for paths not to be
matched correctly.
Now, when computing logical paths, the original absolute paths
are matched against rootDirs in a canonical manner, but the actual
logical path that is returned maintains it original casing.

- Change the Node.js and `yarn` installation instructions to ensure the
`yarn` executable will be available on the `PATH` and not require an
interactive, login shell (as happens, for example, when installing it
via [nvm](https://github.com/nvm-sh/nvm)). This makes it easier to set

In order to avoid unnecessary operations, the `update-preview-server.sh`
script, that is used to update the PR preview server Docker container,
will only try to update the Docker container if either any files in the
`aio/aio-builds-setup/` directory have changed since the last update or
if a previous update failed. A failed previous update is detected by
checking whether the temporary `aio-builds:provisional` Docker image
still exists. This temporary image is created during the update
operation and is renamed to `aio-builds:latest` if the update goes well.
Previously, the update script was not able to detect a previous failed
attempt if the operation failed before creating the
`aio-builds:provisional` Docker image, such as if the `create-image.sh`
script failed. This could lead to a situation where the preview server
Docker container would not be updated after a failed attempt.
This commit improves the logic for detecting failed attempts to account
for this type of failures. It does this by not removing an older
`aio-builds:provisional` Docker image until a new one is successfully
created.
NOTE: While this is not full-proof, it is an improvement as it
eliminates a certain kind of failures.

If one component Parent inherit another component Base like the following:
@Component(...)
class Base {

When creating Component Parent, the dependency injection should work on delegating ctors like above.

class Parent extends Base {
constructor() {
super(...arguments);

The current implementation for redirecting users inside guards was in place
before the feature was added to allow `CanActivate` and `CanActivateChild` guards
to return `UrlTree` for redirecting users.
Returning `UrlTree` should be the default method, as it provides a more desirable
redirecting experience. When using `router.navigate` followed by `return false`,
the `Router` calls `resetUrlToCurrentUrlTree` (in the `finalize` operator) before
processing the navigation to the new route. This can result in an undesirable
history if the navigation was the first navigation in the application - that is,
the route will briefly be reset to just `/` (see #36187).

In the code base there are cases where there is, conceptually, a class
that is represented by a combination of an `interface`
(type declaration) and a `const` (value declaration).
For example:

export interface SomeClass {
count(a?: string): number;
}
export const: SomeClass = class {
someMethod(a: string = ''): number { ... }
};

values.
In this commit such concepts are now rendered as classes.
The classes that are affected by this are:
* `DebugElement`
* `DebugNode`

This is because the anonymous `__exportStar` function will be invoked with the function on the next like as the parameter which is subsequently invoking whatever was returned.

As per our discussion in the dev-infra sync meeting, we don't want
to have all dependencies show up as peer dependencies. Instead, we
only want to have larger dependencies such as `typescript` or buildifier
as peer dependencies. Tslib is also included for the sake of it being
generally a peer dependency of all Angular framework packages.
The rationale is that Yarn is smart enough to collapse packages
if all satisfy a given range. This means that we don't necessarily
need to have all dependencies as peer dependencies. The initial
idea was to keep all dependencies as peer dependencies so that
we have control over duplication of packages as downloading multiple
packages w/ different versions impacts local dev, CI and caches.
At the same time though, we don't want to bother with setting
up peer dependencies all the time. Not every consumer of the
shared dev-infra package would like to manually specify `yaml`
or `multimatch` etc. in the project `package.json`. Hence we
decided to go with a hybrid approach where only more impactful
dependencies are peer dependencies, and other smaller ones can
be standard depdencies that are usually collapsed by Yarn anyway.
Also this commit removes tslib from build targets that don't
rely on it.

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).

are discovered.

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

but an appendix has been added for v10 to the plan document.

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.

but it would involve metadata and NgModule analysis. This is out of

Since we no longer hardcode the `package.json` for
entry-points, a bug has appeared for `ng_package` in Ivy.
The `package.json` files are populated incorrectly with Ivy

As mentioned in previous commits, as of v10 the release output
does no longer contain ESM5 output due to an update to the APF.
This means that the side-effect integration test needs to be

PR Close#36944
As of version 10, libraries following the APF will no longer contain
ESM5 output. Hence, tests in ngcc need to be updated as they currently
rely on the release output of `@angular/core`.
Additionally, we'd need to support in ngcc that the `module`
property of entry-points no longer necessarily refers to
`esm5` output, but instead can also target `esm2015`.
We currently achieve this by checking the path the `module`
property points to. We can do this because as per APF, the
folder name is known for the esm2015 output. Long-term for
more coverage, we want to sniff the format by looking for
known ES2015 constructs in the file `module` refers to.
PR Close#36944
In the past we added support for `ts_library` to `ng_package`. For those
targets we never can determine the "index" file. Unlike `ng_module`,
there is no provider data for flat module bundles, so the `ng_package`
rule assumes that the index file is simply called `index`.
This works as expected, but we also added logic in the past that doesn't
allow `ng_package` to add format properties (e.g. `main`, `module`) to a
`package.json` if a package json is handwritten for such a `ts_library` target.
This has been done that way because we assumed that such `package.json` files
might want to set format properties explicitly to different paths due to a
faulty "index" guess.
We want to change this behavior as most of the time a `package.json`
file already exists with just the module name. In those cases, the
packager should still set the format properties. We should only warn
and skip automatic insertion of the format properties if such a
`package.json` explicitly sets format properties.

This exposes a bug in ngcc, where it can only handle functions that have a
specific form:
```
function forRoot() {

This optimization builds on a lot of prior work to finally make type-
checking of templates incremental.
Incrementality requires two main components:
- the ability to reuse work from a prior compilation.
- the ability to know when changes in the current program invalidate that
prior work.
Prior to this commit, on every type-checking pass the compiler would
generate new .ngtypecheck files for each original input file in the program.
1. (Build #1 main program): empty .ngtypecheck files generated for each
original input file.
2. (Build #1 type-check program): .ngtypecheck contents overridden for those
which have corresponding components that need type-checked.
3. (Build #2 main program): throw away old .ngtypecheck files and generate
new empty ones.
4. (Build #2 type-check program): same as step 2.
With this commit, the `IncrementalDriver` now tracks template type-checking
_metadata_ for each input file. The metadata contains information about
source mappings for generated type-checking code, as well as some
diagnostics which were discovered at type-check analysis time. The actual
type-checking code is stored in the TypeScript AST for type-checking files,
which is now re-used between programs as follows:
1. (Build #1 main program): empty .ngtypecheck files generated for each
original input file.
2. (Build #1 type-check program): .ngtypecheck contents overridden for those
which have corresponding components that need type-checked, and the
metadata registered in the `IncrementalDriver`.
3. (Build #2 main program): The `TypeCheckShimGenerator` now reuses _all_
.ngtypecheck `ts.SourceFile` shims from build #1's type-check program in
the construction of build #2's main program. Some of the contents of
these files might be stale (if a component's template changed, for
example), but wholesale reuse here prevents unnecessary changes in the
contents of the program at this point and makes TypeScript's job a lot
easier.
4. (Build #2 type-check program): For those input files which have not
"logically changed" (meaning components within are semantically the same
as they were before), the compiler will re-use the type-check file
metadata from build #1, and _not_ generate a new .ngtypecheck shim.
For components which have logically changed or where the previous
.ngtypecheck contents cannot otherwise be reused, code generation happens
as before.
PR Close#36211
As a performance optimization, this commit splits the single
__ngtypecheck__.ts file which was previously added to the user's program as
a container for all template type-checking code into multiple .ngtypecheck
shim files, one for each original file in the user's program.
In larger applications, the generation, parsing, and checking of this single
type-checking file was a huge performance bottleneck, with the file often
exceeding 1 MB in text content. Particularly in incremental builds,
regenerating this single file for the entire application proved especially
expensive.
This commit introduces a new strategy for template type-checking code which
makes use of a new interface, the `TypeCheckingProgramStrategy`. This
interface abstracts the process of creating a new `ts.Program` to type-check
a particular compilation, and allows the mechanism there to be kept separate
from the more complex logic around dealing with multiple .ngtypecheck files.
A new `TemplateTypeChecker` hosts that logic and interacts with the
`TypeCheckingProgramStrategy` to actually generate and return diagnostics.
The `TypeCheckContext` class, previously the workhorse of template type-
checking, is now solely focused on collecting and generating type-checking
file contents.
A side effect of implementing the new `TypeCheckingProgramStrategy` in this
way is that the API is designed to be suitable for use by the Angular
Language Service as well. The LS also needs to type-check components, but
has its own method for constructing a `ts.Program` with type-checking code.
Note that this commit does not make the actual checking of templates at all
_incremental_ just yet. That will happen in a future commit.
PR Close#36211
Shim generation was built on a lie.
Shims are files added to the program which aren't original files authored by
the user, but files authored effectively by the compiler. These fall into
two categories: files which will be generated (like the .ngfactory shims we
generate for View Engine compatibility) as well as files used internally in
compilation (like the __ng_typecheck__.ts file).
Previously, shim generation was driven by the `rootFiles` passed to the
compiler as input. These are effectively the `files` listed in the
`tsconfig.json`. Each shim generator (e.g. the `FactoryGenerator`) would
examine the `rootFiles` and produce a list of shim file names which it would
be responsible for generating. These names would then be added to the
`rootFiles` when the program was created.
The fatal flaw here is that `rootFiles` does not always account for all of
the files in the program. In fact, it's quite rare that it does. Users don't
typically specify every file directly in `files`. Instead, they rely on
TypeScript, during program creation, starting with a few root files and
transitively discovering all of the files in the program.
This happens, however, during `ts.createProgram`, which is too late to add
new files to the `rootFiles` list.
As a result, shim generation was only including shims for files actually
listed in the `tsconfig.json` file, and not for the transitive set of files
in the user's program as it should.
This commit completely rewrites shim generation to use a different technique
for adding files to the program, inspired by View Engine's shim generator.
In this new technique, as the program is being created and `ts.SourceFile`s
are being requested from the `NgCompilerHost`, shims for those files are
generated and a reference to them is patched onto the original file's
`ts.SourceFile.referencedFiles`. This causes TS to think that the original
file references the shim, and causes the shim to be included in the program.
The original `referencedFiles` array is saved and restored after program
creation, hiding this little hack from the rest of the system.
The new shim generation engine differentiates between two kinds of shims:
top-level shims (such as the flat module entrypoint file and
__ng_typecheck__.ts) and per-file shims such as ngfactory or ngsummary
files. The former are included via `rootFiles` as before, the latter are
included via the `referencedFiles` of their corresponding original files.
As a result of this change, shims are now correctly generated for all files
in the program, not just the ones named in `tsconfig.json`.
A few mitigating factors prevented this bug from being realized until now:
* in g3, `files` does include the transitive closure of files in the program
* in CLI apps, shims are not really used
This change also makes use of a novel technique for associating information
with source files: the use of an `NgExtension` `Symbol` to patch the
information directly onto the AST object. This is used in several
circumstances:
* For shims, metadata about a `ts.SourceFile`'s status as a shim and its
origins are held in the extension data.
* For original files, the original `referencedFiles` are stashed in the
extension data for later restoration.
The main benefit of this technique is a lot less bookkeeping around `Map`s
of `ts.SourceFile`s to various kinds of data, which need to be tracked/
invalidated as part of incremental builds.
This technique is based on designs used internally in the TypeScript
compiler and is serving as a prototype of this design in ngtsc. If it works
well, it could have benefits across the rest of the compiler.
PR Close#36211
The compiler needs to track the dependencies of a component, including any
NgModules which happen to be present in a component's scope. If an upstream
NgModule changes, any downstream components need to have their templates
re-compiled and re-typechecked.
Previously, the compiler handled this well for the A -> B -> C case where
module A imports module B which re-exports module C. However, it fell apart
in the A -> B -> C -> D case, because previously tracking focused on changes
to components/directives in the scope, and not NgModules specifically.
This commit introduces logic to track which NgModules contributed to a given
scope, and treat them as dependencies of any components within.
This logic also contains a bug, which is intentional for now. It
purposefully does not track transitive dependencies of the NgModules which
contribute to a scope. If it did, using the current dependency system, this
would treat all components and directives (even those not exported into the
scope) as dependencies, causing a major performance bottleneck. Only those
dependencies which contributed to the module's export scope should be
considered, but the current system is incapable of making this distinction.
This will be fixed at a later date.

Previously, in the `test_aio` CI job, we ran ngcc before building the
app with `yarn build`. This was supposed to have the benefit of taking
advantage of the parallel capabilities of standalone ngcc (vs implicitly
running it via `ng build`).
It turns out that the work done by the standalone ngcc was thrown away
before the `ng build`, resulting in `ng build` having to run ngcc all
over again. This happened because the `yarn build` script (run after the
standalone ngcc step) also runs `yarn install`, which essentially cleans
up `node_modules/`, thus discarding all the work already done by ngcc.
Here is an [example CI job][1], where this can be seen in action:
One can see the "Compiling <some-package> : es2015 as esm2015" logs in
the `yarn --cwd aio ngcc --properties es2015` step (as the standalone
ngcc processes the various entry-points) and then see the same logs in
the `yarn --cwd aio build --progress=false` step (as ngcc has to process
the entry-points all over again).
This commit removes the redundant standalone ngcc run and lets the CLI
handle ngcc via `ng build`. It is possible to instrument the build
process in a way that we can run the standalone ngcc after
`yarn install` and thus take advantage of the performance gains in
parallel mode, but the latest version of the CLI can already run ngcc in
parallel mode as a pre-build step, so this is unnecessary.

This commit adds a new mock host for testing the ivy language service.
Unlike the existing mock_host which mocks the LanguageServiceHost, the
Ivy mock host mocks just the filesystem interface, aka ts.ServerHost.
This is because Ivy language service requires an actual Project to
perform operations like adding synthetic typecheck files to the project,
and by extension, to the ts.Program. These requirements make the existing
mock host unsuitable to be reused.
This new testing structure also improves test performance, because the
old mock host copies (it actually creates symlinks, but still that's
relatively expensive due to the sheer number of files involved) all
@angular/* packages along with the typescript package to a temporary
node_modules directory. This is done every time setup() is called.

The Angular ServiceWorker always uses a copy of the request without
headers for caching assets (in order to avoid issues with opaque
responses). Therefore, it was previously not possible to retrieve
resources from the cache if the response contained [Vary](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Vary) headers.
In addition to that, `Vary` headers do not work in all browsers (or work
differently) and may not work as intended with ServiceWorker caches. See
[this article](https://www.smashingmagazine.com/2017/11/understanding-vary-header) and the linked resources for more info.
This commit avoids the aforementioned issues by making sure the Angular
ServiceWorker always sets the `ignoreVary` option passed to
[Cache#match()](https://developer.mozilla.org/en-US/docs/Web/API/Cache/match) to `true`. This allows the ServiceWorker to correctly
retrieve cached responses with `Vary` headers, which was previously not
possible.

behavior due to inconsistent/buggy implementations in different
browsers.
Now, `Vary` headers are ignored when retrieving resources from the
ServiceWorker caches, which can result in resources being retrieved even
when their headers are different. If your application needs to
differentiate its responses based on request headers, please make sure

When running in parallel mode, worker processes forward errors thrown
during task processing to the master process, which in turn exits with
an error.
However, there are cases where the error is not directly related to
processing the entry-point. One such case is when there is not enough
memory (for example, due to all the other tasks being processed
simultaneously).
Previously, an `ENOMEM` error thrown on a worker process would propagate
to the master process, eventually causing ngcc to exit with an error.
Example failure: https://circleci.com/gh/angular/angular/682198
This commit improves handling of these low-memory situations by
detecting `ENOMEM` errors and killing the worker process, thus allowing
the master process to decide how to handle that. The master process will
put the task back into the tasks queue and continue processing tasks
with the rest of the worker processes (and thus with lower memory
pressure).

Previously, when the last worker process crashed, the master process
would try to re-spawn it indefinitely. This could lead to an infinite

PR Close#36626
Previously, when running in parallel mode and a worker process crashed
while processing a task, it was not possible for ngcc to continue
without risking ending up with a corrupted entry-point and therefore it
exited with an error. This, for example, could happen when a worker
process received a `SIGKILL` signal, which was frequently observed in CI
environments. This was probably the result of Docker killing processes
due to increased memory pressure.
One factor that amplifies the problem under Docker (which is often used
in CI) is that it is not possible to distinguish between the available
CPU cores on the host machine and the ones made available to Docker
containers, thus resulting in ngcc spawning too many worker processes.
This commit addresses these issues in the following ways:
1. We take advantage of the fact that files are written to disk only
after an entry-point has been fully analyzed/compiled. The master
process can now determine whether a worker process has not yet
started writing files to disk (even if it was in the middle of
processing a task) and just put the task back into the tasks queue if
the worker process crashes.
2. The master process keeps track of the transformed files that a worker
process will attempt to write to disk. If the worker process crashes
while writing files, the master process can revert any changes and
put the task back into the tasks queue (without risking corruption).
3. When a worker process crashes while processing a task (which can be a
result of increased memory pressure or too many worker processes),
the master process will not try to re-spawn it. This way the number
or worker processes is gradually adjusted to a level that can be
accomodated by the system's resources.
Examples of ngcc being able to recover after a worker process crashed:
- While idling: https://circleci.com/gh/angular/angular/682197

Previously, ngcc would run in parallel mode (using the

reserved for the master process). In these cases, the tasks would still
be processed serially (on the one worker process), but we would also pay

The html parser already normalizes line endings (converting `\r\n` to `\n`)
for most text in templates but it was missing the expressions of ICU expansions.
In ViewEngine backticked literal strings, used to define inline templates,
were already normalized by the TypeScript parser.
In Ivy we are parsing the raw text of the source file directly so the line
endings need to be manually normalized.
This change ensures that inline templates have the line endings of ICU
expression normalized correctly, which matches the ViewEngine.
In ViewEngine external templates, defined in HTML files, the behavior was
different, since TypeScript was not normalizing the line endings.
Specifically, ICU expansion "expressions" are not being normalized.
This is a problem because it means that i18n message ids can be different on
different machines that are setup with different line ending handling,
or if the developer moves a template from inline to external or vice versa.
The goal is always to normalize line endings, whether inline or external.
But this would be a breaking change since it would change i18n message ids
that have been previously computed. Therefore this commit aligns the ivy
template parsing to have the same "buggy" behavior for external templates.
There is now a compiler option `i18nNormalizeLineEndingsInICUs`, which
if set to `true` will ensure the correct non-buggy behavior. For the time
being this option defaults to `false` to ensure backward compatibility while
allowing opt-in to the desired behavior. This option's default will be
flipped in a future breaking change release.
Further, when this option is set to `false`, any ICU expression tokens,
which have not been normalized, are added to the `ParseResult` from the
`HtmlParser.parse()` method. In the future, this collection of tokens could
be used to diagnose and encourage developers to migrate their i18n message
ids. See FW-2106.

of at least 100 characters. This is meant to encourage commits
within the repo to be more descriptive of each change.
PR Close#36632
Previously, the commit message body regex only matched the first line
of the body. This change corrects the regex to match the entire line.

Currently, if changes are made to `compiler-cli/ngcc` and to other
compiler-related files, then only the `fw-ngcc` group is requested
for review. This is because the `not contains_any_globs` condition
will be false for `fw-compiler` and the group will never become active.
We fix this by removing the incorrect condition and filtering out ngcc
files before checking `contains_any_globs` in the primary fw-compiler
condition.
PR Close#36661
Currently, when verifying our pullapprove configuration, we don't
respect modifications to the set of files in a condition.
e.g. It's not possible to do the following:
```
contains_any_globs(files.exclude(...), [
```
This prevents us from having codeowner groups which match a directory,
but want to filter out specific sub directories. For example, `fw-core`
matches all files in the core package. We want to exclude the schematics
from that glob. Usually we do this by another exclude condition.
This has a *significant* downside though. It means that fw-core will not
be requested if a PR changes schematic code, _and_ actual fw-core code.
To support these conditions, the pullapprove verification tool is
refactored, so that it no longer uses Regular expressions for parsing,
but rather evaluates the code through a dynamic function. This is
possible since the conditions are written in simple Python that can
be run in NodeJS too (with small modifications/transformations).

When module overrides (via `TestBed.overrideModule`) are present, it might affect all modules that import (even transitively) an overridden one. For all affected modules we need to recalculate their scopes for a given test run and restore original scopes at the end. Prior to this change, we were recalculating module scopes only for components that are used in a test, without taking into account module hierarchy. This commit updates Ivy TestBed logic to calculate all potentially affected modules are reset cached scopes information for them (so that scopes are recalculated as needed).

Prior to this commit unbound attributes were treated as possible inputs to structural directives. Since structural directives can only accepts inputs defined using microsyntax expression (e.g. `<div *dir="exp">`), such unbound attributes should not be considered as inputs. This commit aligns Ivy and View Engine behavior and avoids using unbound attributes as inputs to structural directives.

Based on the migration guide, provided classes which don't have
either `@Injectable`, `@Directive`, `@Component` or `@Pipe` need
to be migrated.
This is not correct as provided classes with an `@NgModule` also
have a factory function that can be read by the r3 injector. It's
unclear in which cases the `@NgModule` decorator is used for
provided classes, but this scenario has been reported.
Either we fix this in the migration, or we make sure to report
this as unsupported in the Ivy compiler.

The cached file-system was implemented to speed up ngcc
processing, but in reality most files are not accessed many times
and there is no noticeable degradation in speed by removing it.
Benchmarking `ngcc -l debug` for AIO on a local machine
gave a range of 196-236 seconds with the cache and 197-224
seconds without the cache.
Moreover, when running in parallel mode, ngcc has a separate
file cache for each process. This results in excess memory usage.
Notably the master process, which only does analysis of entry-points
holds on to up to 500Mb for AIO when using the cache compared to
only around 30Mb when not using the cache.
Finally, the file-system cache being incorrectly primed with file
contents before being processed has been the cause of a number
of bugs. For example https://github.com/angular/angular-cli/issues/16860#issuecomment-614694269.

This commit fixes how the language service evaluates the compatibility
of types to work with arbitrary union types. As a result, compatibility
checks are now more strict and can catch similarities or differences
more clearly.
```
number|string == string|null // OK
number|string == number // OK
number|string == null // not comparable
number == string // not comparable
```
Using Ivy as a backend should provide these diagnoses for free, but we
can backfill them for now.

The change in e041ac6f0d
to support sending unlocker process output to the main ngcc
console output prevents messages require that the main process
relinquishes the event-loop to allow the `stdout.on()` handler to
run. This results in none of the messages being written when ngcc
is run in `--no-async` mode, and some messages failing to be
written if the main process is killed (e.g. ctrl-C).
It appears that the problem with Windows and detached processes
is known - see https://github.com/nodejs/node/issues/3596#issuecomment-250890218.
But in the meantime, this commit is a workaround, where non-Windows
`inherit` the main process `stdout` while on Windows it reverts
to the async handler approach, which is better than nothing.

In the past, server-side rendered apps needed to convert URLs used in
API requests to absolute when rendering on the server. Originally, this
was handled in the `universal` guide and corresponding example app by
modifying the `HeroService` to use `APP_BASE_HREF` to derive the
absolute URL.
In #28956, the guide was updated to show an improved method: Specifying
an `HttpInterceptor` that took care of converting the URLs to absolute.
That interceptor was only provided when rendering the app on the server.
By mistake, the corresponding example app was not updated along with the
guide.
Since `@nguniversal/*` v7.1.0, it is no longer necessary to convert the
URLs to absolute inside the app. This is handled in the `@nguniversal`
libs (see angular/universal#897).
This commit updates the example app to remove unnecessary code and
modifies the guide to mention the issue with absolute URLs, but explain
that developers only need to worry about it when not using one of the
`@nguniversal/*-engine` packages.

When formatting a time with the `b` or `B` format codes, the rendered
string was not correctly handling day periods that spanned midnight.
Instead the logic was falling back to the default case of `AM`.
Now the logic has been updated so that it matches times that are within
a day period that spans midnight, so it will now render the correct
output, such as `at night` in the case of English.
Applications that are using either `formatDate()` or `DatePipe` and any
of the `b` or `B` format codes will be affected by this change.

* **core** make generic mandatory for ModuleWithProviders ([#36892](https://github.com/angular/angular/issues/36892)) ([20cc3ab](https://github.com/angular/angular/commit/20cc3ab))
### BREAKING CHANGES
* **core:** make generic mandatory for ModuleWithProviders
A generic type parameter has always been required for the `ModuleWithProviders` pattern to work with Ivy, but prior to this commit, View Engine allowed the generic type to be omitted (though support was officially deprecated).
If you're using `ModuleWithProviders` without a generic type in your application code, a v10 migration will update your code for you.
However, if you are using View Engine and also depending on a library that omits the generic type, you will now get a build time error similar to:
```
error TS2314: Generic type 'ModuleWithProviders<T>' requires 1 type argument(s).
```
In this case, ngcc won't help you (because it's Ivy-only) and the migration only covers application code.
You should contact the library author to fix their library to provide a type parameter when they use this class.
As a workaround, we suggest setting `skipLibChecks` to false in your tsconfig or updating your app to use Ivy.

* remove TypeScript 3.6 and 3.7 support ([#36329](https://github.com/angular/angular/issues/36329)) ([fbd281c](https://github.com/angular/angular/commit/fbd281c))
* TypeScript versions 3.6 and 3.7 are no longer supported, please update to TypeScript 3.8
* **forms:** 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()`.
* **forms:** The `minLength` and `maxLength` validators now verify that the form control's value has a
numeric `length` property, and only validate for length if that's the case.
Previously, falsey values without the length property (such as `0` or
`false` values) were triggering validation errors. If your code relies on
the old behavior, you can include other validators such as [min][1] or
[requiredTrue][2] to the list of validators for a particular field.

### BREAKING CHANGES
* **common:** format day-periods that cross midnight
When formatting a time with the `b` or `B` format codes, the rendered
string was not correctly handling day periods that spanned midnight.
Instead the logic was falling back to the default case of `AM`.
Now the logic has been updated so that it matches times that are within
a day period that spans midnight, so it will now render the correct
output, such as `at night` in the case of English.
Applications that are using either `formatDate()` or `DatePipe` and any
of the `b` or `B` format codes will be affected by this change.

A minimal reproduction allows us to quickly confirm a bug (or point out a coding problem) as well as confirm that we are fixing the right problem.
We will be insisting on a minimal reproduction scenario in order to save maintainers time and ultimately be able to fix more bugs. Interestingly, from our experience, users often find coding problems themselves while preparing a minimal reproduction. We understand that sometimes it might be hard to extract essential bits of code from a larger codebase but we really need to isolate the problem before we can fix it.
