Prior to this change, a method call of a local template variable would
incorrectly be considered a call to a method on the component class.
For example, this pattern would produce an error:
```
<ng-template let-method>{{ method(1) }}</ng-template>
```
Here, the method call should be targeting the `$implicit` variable on
the template context, not the component class. This commit corrects the
behavior by first resolving methods in the template before falling back
on the component class.

Libraries can expose directive/component base classes that will be
used by consumer applications. Using such a base class from another
compilation unit works fine with "ngtsc", but when using "ngc", the
compiler will thrown an error saying that the base class is not
part of a NgModule. e.g.
```
Cannot determine the module for class X in Y! Add X to the NgModule to fix it.

This seems to be because the logic for distinguishing directives from
abstract directives is scoped to the current compilation unit within
ngc. This causes abstract directives from other compilation units to

It looks like the gulp setup does not work with NodeJS v12. This
is because we still use gulp for a few tasks, but gulp v3 is not
compatible with NodeJS v12. We had a similar issue for NodeJS v12,

To actually solve this in a more future-proof way, without
updating or removing Gulp (for now), we just overwrite the
`graceful-fs` version. The latest version of `graceful-fs`
does no longer depend on the `natives` package and therefore
works properly with NodeJS >= v10.

This commit adapts the private NgModule re-export system (using aliasing) to
ngcc. Not all ngcc compilations are compatible with these re-exports, as
they assume a 1:1 correspondence between .js and .d.ts files. The primary
concern here is supporting them for commonjs-only packages.
PR Close#33177
This commit refactors the aliasing system to support multiple different
AliasingHost implementations, which control specific aliasing behavior
in ngtsc (see the README.md).
A new host is introduced, the `PrivateExportAliasingHost`. This solves a
longstanding problem in ngtsc regarding support for "monorepo" style private
libraries. These are libraries which are compiled separately from the main
application, and depended upon through TypeScript path mappings. Such
libraries are frequently not in the Angular Package Format and do not have
entrypoints, but rather make use of deep import style module specifiers.
This can cause issues with ngtsc's ability to import a directive given the
module specifier of its NgModule.
For example, if the application uses a directive `Foo` from such a library
`foo`, the user might write:
```typescript
import {FooModule} from 'foo/module';
```
In this case, foo/module.d.ts is path-mapped into the program. Ordinarily
the compiler would see this as an absolute module specifier, and assume that
the `Foo` directive can be imported from the same specifier. For such non-
APF libraries, this assumption fails. Really `Foo` should be imported from
the file which declares it, but there are two problems with this:
1. The compiler would have to reverse the path mapping in order to determine
a path-mapped path to the file (maybe foo/dir.d.ts).
2. There is no guarantee that the file containing the directive is path-
mapped in the program at all.
The compiler would effectively have to "guess" 'foo/dir' as a module
specifier, which may or may not be accurate depending on how the library and
path mapping are set up.
It's strongly desirable that the compiler not break its current invariant
that the module specifier given by the user for the NgModule is always the
module specifier from which directives/pipes are imported. Thus, for any
given NgModule from a particular module specifier, it must always be
possible to import any directives/pipes from the same specifier, no matter
how it's packaged.
To make this possible, when compiling a file containing an NgModule, ngtsc
will automatically add re-exports for any directives/pipes not yet exported
by the user, with a name of the form: ɵngExportɵModuleNameɵDirectiveName
This has several effects:
1. It guarantees anyone depending on the NgModule will be able to import its
directives/pipes from the same specifier.
2. It maintains a stable name for the exported symbol that is safe to depend
on from code on NPM. Effectively, this private exported name will be a
part of the package's .d.ts API, and cannot be changed in a non-breaking
fashion.

Static methods that return a type of ModuleWithProviders currently
do not have to specify a type because the generic falls back to any.
This is problematic because the type of the actual module being
returned is not present in the type information.
Since Ivy uses d.ts files exclusively for downstream packages
(rather than metadata.json files, for example), we no longer have
the type of the actual module being created.
For this reason, a generic type should be added for
ModuleWithProviders that specifies the module type. This will be
required for all users in v10, but will only be necessary for
users of Ivy in v9.

Previously, the `FileSystem` abstraction featured a `mkdir()` method. In
`NodeJSFileSystem` (the default `FileSystem` implementation used in
actual code), the method behaved similar to Node.js' `fs.mkdirSync()`
(i.e. failing if any parent directory is missing or the directory exists
already). In contrast, `MockFileSystem` (which is the basis or mock
`FileSystem` implementations used in tests) implemented `mkdir()` as an
alias to `ensureDir()`, which behaved more like Node.js'
`fs.mkdirSync()` with the `recursive` option set to `true` (i.e.
creating any missing parent directories and succeeding if the directory
exists already).
This commit fixes this inconsistency by removing the `mkdir()` method,
which was not used anyway and only keeping `ensureDir()` (which is
consistent across our different `FileSystem` implementations).

When `ngcc` is running in parallel mode (usually when run from the
command line) and the `createNewEntryPointFormats` option is set to true
(e.g. via the `--create-ivy-entry-points` command line option), it can
happen that two workers end up trying to create the same directory at
the same time. This can lead to a race condition, where both check for
the directory existence, see that the directory does not exist and both
try to create it, with the second failing due the directory's having
already been created by the first one. Note that this only affects
directories and not files, because `ngcc` tasks operate on different
sets of files.
This commit avoids this race condition by allowing `FileSystem`'s
`ensureDir()` method to not fail if one of the directories it is trying
to create already exists (and is indeed a directory). This is fine for
the `ensureDir()` method, since it's purpose is to ensure that the
specified directory exists. So, even if the `mkdir()` call failed
(because the directory exists), `ensureDir()` has still completed its
mission.

Often the types of an `@Input`'s field don't fully reflect the types of
assignable values. This can happen when an input has a getter/setter pair
where the getter always returns a narrow type, and the setter coerces a
wider value down to the narrow type.
For example, you could imagine an input of the form:
```typescript
@Input() get value(): string {
return this._value;
}
set value(v: {toString(): string}) {
this._value = v.toString();
}
```
Here, the getter always returns a `string`, but the setter accepts any value
that can be `toString()`'d, and coerces it to a string.
Unfortunately TypeScript does not actually support this syntax, and so
Angular users are forced to type their setters as narrowly as the getters,
even though at runtime the coercion works just fine.
To support these kinds of patterns (e.g. as used by Material), this commit
adds a compiler feature called "input coercion". When a binding is made to
the 'value' input of a directive like MatInput, the compiler will look for a
static function with the name ngCoerceInput_value. If such a function is
found, the type-checking expression for the input will be wrapped in a call
to the function, allowing for the expression of a type conversion between
the binding expression and the value being written to the input's field.
To solve the case above, for example, MatInput might write:
```typescript
class MatInput {
// rest of the directive...
static ngCoerceInput_value(value: {toString(): string}): string {
return null!;
}
}
```

Without this change when using UrlTree redirects in urlUpdateStrategy="eager", the URL would get

Additionally, there was a bug where the redirect, even without urlUpdateStrategy="eager", could
create a history with too many entries. This was due to kicking off a new navigation within the
navigation cancelling logic. With this PR the new navigation is pushed to the next tick with a
setTimeout, allowing the page being redirected from to be cancelled before starting a new

Given that the same local packages are used for both `aio/` and the

execution on CI, we do not need to build the packages there, because the

However, the various setup npm scripts were not implemented correctly to

`aio-use-local` would build the packages, while `example-use-local`
would not (it was supposed to use the already built packages from

`--build-packages` option, that (if passed) will result in building the
local packages as well.
Given that the same local packages are used for both `aio/` and the
examples, we only need to build the packages once. Also, to speed up
execution on CI, we do not need to build the packages there, because the
packages would have been built already in a previous CI job.
However, the various setup npm scripts were not implemented correctly to
meet these requirements. Specifically, when running locally,
`aio-use-local` would build the packages, while `example-use-local`
would not (it was supposed to use the already built packages from
`aio-use-local`). The `example-use-local` script, though, was configured
to run before `aio-use-local`. As a result, the packages were not built,
by the time `example-use-local` needed them, which would cause an error.
This commit fixes it by ensuring that `aio-use-local` (which builds the
local Angular packages) runs before `example-use-local`, so that the
latter can use the same packages already built by the former.

Previously, we would only consider the `es2015` property, but some
packages (such as `angular-in-memory-web-api`) may not have that. They
might still be compilable by `ngcc`, is they have other format

This change assures that data structures related to initial inputs
(ones set from static attributes) are created only once (during the
first template pass) and no additional runtime checks are done for
subsequent passes.
Additionally this commit changes the data structure used by initial inputs
on TNode - previously initial inputs for a directive were stored at the
directive index in LView. This meant that an array holding initial inputs
was relativelly big and had many null elements (as placeholders for elements,
directives, injector etc.). After the change we only create an array of a size
equal to a number of directives matched on a given TNode.
For the `directive_instantiate` benchmark it boils to allocating a 1-element
array vs. 100-element array previously.

Now, hovering over an attribute on an element will provide information
about the directive that attribute matches in the element, if any.
(More generally, we return information about directive symbols
matched on an element attribute.)
I believe this is similar to how the indexer provides this kind of
information, though more precise in the sense that this commit provides
directive information only if the directive selector exactly matches the
attribute selector. In another sense, this is a limitation.
In fact, there are the limitations of:
- Directives matched on the element, but with a selector of anything
more than the attribute (e.g. `div[string-model]` or
`[string-model][other-attr]`) will not be returned as symbols matching
on the attribute.
- Only one symbol can be returned currently. If the attribute matches
multiple directives, only one directive symbol will be returned.
Furthermore, we cannot say that the directive symbol returned is
determinstic.
Resolution of these limitations can be discussed in the future. At least
the second limitation should be very easy to fixup in a future commit.
This relies solely on the template compiler and is agnostic to any Ivy
changes, so this is strictly a feature enhancement that will not have to
be refactored when we migrate the language service to Ivy.

The `payload-size.sh` script is mainly used on CI to calculate, check
and potentially save (on non-PR builds) the sizes of the bundles for
various apps (including angular.io). If everything goes well (i.e. the
checks pass, meaning that the sizes did not increase above the specified
threshold) nothing is shown in the CI logs.
In some cases, it is useful to be able to see what the sizes were in a
specific build; e.g. for debugging purposes or when investigating a
gradual increase that happened over time. (Some of this info is
available on https://size.angular.io/, but not all.)
Previously, the only way to find out what the sizes were for a specific
build was to checkout the corresponding commit locally and build the
target app, which in turn requires building all Angular packages and can
take some time. Given that the sizes are already calculated on CI, this
was a waste.

Prior to this change, a static attribute that corresponds with a
directive's input would not be type-checked against the type of the

Prior to this change, the template type checker would always allow a
value of type `undefined` to be passed into a directive's inputs, even
if the input's type did not allow for it. This was due to how the type
constructor for a directive was generated, where a `Partial` mapped
type was used to allow for inputs to be unset. This essentially
introduces the `undefined` type as acceptable type for all inputs.
This commit removes the `Partial` type from the type constructor, which
means that we can no longer omit any properties that were unset.
Instead, any properties that are not set will still be included in the
type constructor call, having their value assigned to `any`.
Before:
```typescript
class NgForOf<T> {
static ngTypeCtor<T>(init: Partial<Pick<NgForOf<T>,
'ngForOf'|'ngForTrackBy'|'ngForTemplate'>>): NgForOf<T>;
}

Currently the `ngForOf` input accepts `null` or `undefined` as valid
values. Although when using strict template input type checking
(which will be supported by `ngtsc`), passing `null` or `undefined`
with strict null checks enabled causes a type check failure because
the type for the `ngForOf` input becomes too strict if strict null checks
are enabled. The type of the input needs to be expanded to also accept
`null` or `undefined` to behave consistently regardless of the
`strictNullChecks` flag.
This is necessary because whenever strict input type checking is enabled
by default, most of the Angular projects that use `*ngFor` with the async pipe
will either need to disable template type checking or strict null checks
because the `async` pipe returns `null` if the observable hasn't been
emitted yet.

In View Engine, animation metadata could occur in nested arrays which
would be flattened in the compiler. When compiling a component for Ivy
however, the compiler no longer statically evaluates a component's
animation metadata and is therefore unable to flatten it statically.
This resulted in an issue to find animations at runtime, as the metadata
was incorrectly registered with the animation engine.
Although it would be possible to statically evaluate the animation
metadata in ngtsc, doing so would prevent reusable animations exported
from libraries from being usable as ngtsc's partial evaluator is unable
to read values inside libraries. This is unlike ngc's usage of static
symbols represented in a library's `.metadata.json`, which explains how
the View Engine compiler is able to flatten the animation metadata
statically.
As an alternative solution, the metadata flattening is now done in the
runtime during the registration of the animation metadata with the
animation engine.

`Validators.email()` is a slightly enhanced version of the
[WHATWG one](https://html.spec.whatwg.org/multipage/input.html#valid-e-mail-address).
This commit refactors the regexp (without changing its behavior) to make
it more closely match the format of WHATWG version, so that it is easier
for people to compare it against the WHATWG one and understand the
differences.
The main changes were:
- Changing the order of characters/character classes inside `[...]`;
e.g. `[A-Za-z]` --> `[a-zA-Z]`
- Mark all groups as non-capturing (since we do not use the captured
values); e.g. `(foo)` --> `(?:foo)`
(This could theoretically also have a positive performance impact, but
I suspect JavaScript engines are already optimizing away capturing
groups when they are not used.)
PR Close#32961
Previously, there was no documentation of what `Validators.email()`
expects as a valid e-mail address, making it difficult for people to
determine whether it covers their requirements or not. Even more so that
the used pattern slightly deviates from the
[WHATWG version](https://html.spec.whatwg.org/multipage/input.html#valid-e-mail-address).
One's only option was to look at the source code and try to decipher the
regexp pattern.
This commit adds a high-level description of the validator and mentions
its similarity to and differences from the WHATWG version. It also adds
a brief explanation of the regexp's behavior and references for more
information in the source code to provide more context to
maintainers/users trying to understand the implementation in the future.

The `init_environment` custom command is used in almost all other jobs.
The this is implemented in CircleCI is that the steps of the command are
inlined into the other jobs.
Some of the `init_environment` commands are quite long and (since the
default display name for a step is its command) they clutter the
CircleCI UI. Additionally, multiple related commands are shown as
separate steps, which makes it more difficult to get to the actual steps

Currently the undecorated-classes-with-di migration leverages NGC in order
to work with metadata resolution. Since NGC by default tries to resolve referenced
resources on initialization of the underlying TS program, it can result in unexpected
migration failures due to missing resource files.
This is especially an issue since the CLI wraps the `AngularCompilerProgram` with
special logic (i.e. to support SCSS preprocessing etc.). We don't have all of this since
we instantiate a vanilla NGC program.
The solution to the problem is to simply treat resource requests as valid, and returning
a fake content. The migration is not dependent on templates or stylesheets.. so it's the
simplest and most robust solution.

ec4381d explicitly set `enableIvy: false` for all migrations inside
the core package. This actually hides migration issues because the
migration itself should ensure that it instantiates the right
compiler program if it relies on `@angular/compiler-cli`.
We should remove these options from all migration tests to
ensure that we catch issues with migrations running in version
9 where Ivy is enabled by default.

ec4381d enabled Ivy by default. This is problematic as migrations
like `static-queries` depend on the `AngularCompilerProgram` (NGC)
in order to perform the migration from version 7 to version 8.
In order to ensure that the migration always runs with NGC
(and doesn't get the `NgtscProgram`), we need to explicitly disable
ivy when creating the `@angular/compiler-cli` program for the migration.
This code is still relevant even though the update from version 7
to version 8 landed. Developers can run `ng update` from version 7
and immediately get to version 9 where Ivy is enabled by default (and in
that case we need to ensure that ngtsc is not accidentally used).

In an attempt to be compatible with previous translation files
the Angular compiler was generating instructions that always
included the message id. This was because it was not possible
to accurately re-generate the id from the calls to `$localize()` alone.
In line with https://hackmd.io/EQF4_-atSXK4XWg8eAha2g this
commit changes the compiler so that it only renders ids if they are
"custom" ones provided by the template author.
NOTE:
When translating messages generated by the Angular compiler
from i18n tags in templates, the `$localize.translate()` function
will compute message ids, if no custom id is provided, using a
common digest function that only relies upon the information
available in the `$localize()` calls.
This computed message id will not be the same as the message
ids stored in legacy translation files. Such files will need to be
migrated to use the new common digest function.
This only affects developers who have been trialling `$localize`, have
been calling `loadTranslations()`, and are not exclusively using custom
ids in their templates.

With #31953 we moved the factories for components, directives and pipes into a new field called `ngFactoryDef`, however I decided not to do it for injectables, because they needed some extra logic. These changes set up the `ngFactoryDef` for injectables as well.
For reference, the extra logic mentioned above is that for injectables we have two code paths:
1. For injectables that don't configure how they should be instantiated, we create a `factory` that proxies to `ngFactoryDef`:
```
// Source
@Injectable()
class Service {}
// Output
class Service {
static ngInjectableDef = defineInjectable({
factory: () => Service.ngFactoryFn(),
});
static ngFactoryFn: (t) => new (t || Service)();
}
```
2. For injectables that do configure how they're created, we keep the `ngFactoryDef` and generate the factory based on the metadata:
```
// Source
@Injectable({
useValue: DEFAULT_IMPL,
})
class Service {}
// Output
export class Service {
static ngInjectableDef = defineInjectable({
factory: () => DEFAULT_IMPL,
});
static ngFactoryFn: (t) => new (t || Service)();
}

1. A user has a custom implementation of lazy-loaded modules, sets some

then compiles. This is problematic because we need to be sure the module
registered in the first test is not used, so we need to clear it out of
the modules list in `ng_module_factory_registration`.
2. A user has a similar lazy-loaded module factory implementation but

Recently ng-packagr was updated to include a transform that used to be
done in tsickle (https://github.com/ng-packagr/ng-packagr/pull/1401),
where only constructor parameter decorators are emitted in tsickle's
format, not any of the other decorators.
ngcc used to extract decorators from only a single format, so once it
saw the `ctorParameters` static property it assumed the library is using
the tsickle format. Therefore, none of the `__decorate` calls were
considered. This resulted in missing decorator information, preventing
proper processing of a package.
This commit changes how decorators are extracted by always looking at
both the static properties and the `__decorate` calls, merging these
sources appropriately.

ngcc may need to insert public exports into the bundle's source as well
as to the entry-point's declaration file, as the Ivy compiler may need
to create import statements to internal library types. The way ngcc
knows which exports to add is through the references registry, to which
references to things that require a public export are added by the
various analysis steps that are executed.
One of these analysis steps is the augmentation of declaration files
where functions that return `ModuleWithProviders` are updated so that a
generic type argument is added that corresponds with the `NgModule` that
is actually imported. This type has to be publicly exported, so the
analyzer step has to add the module type to the references registry.
A problem occurs when `ModuleWithProviders` already has a generic type
argument, in which case no update of the declaration file is necessary.
This may happen when 1) ngcc is processing additional bundle formats, so
that the declaration file has already been updated while processing the
first bundle format, or 2) when a package is processed which already
contains the generic type in its source. In both scenarios it may occur
that the referenced `NgModule` type does not yet have a public export,
so it is crucial that a reference to the type is added to the
references registry, which ngcc failed to do.
This commit fixes the issue by always adding the referenced `NgModule`
type to the references registry, so that a public export will always be
created if necessary.

Now that the `$localize` translations are `MessageId` based the
compiler must render `MessageId`s in its generated `$localize` code.
This is because the `MessageId` used by the compiler is computed
from information that does not get passed through to the `$localize`
tagged string.
For example, the generated code for the following template
```html
<div id="static" i18n-title="m|d" title="introduction"></div>
```
will contain these localization statements
```ts
if (ngI18nClosureMode) {
/**
* @desc d
* @meaning m
*/
const MSG_EXTERNAL_8809028065680254561$$APP_SPEC_TS_1 = goog.getMsg("introduction");
I18N_1 = MSG_EXTERNAL_8809028065680254561$$APP_SPEC_TS_1;
}
else {
I18N_1 = $localize \`:m|d@@8809028065680254561:introduction\`;
}
```
Since `$localize` is not able to accurately regenerate the source-message
(and so the `MessageId`) from the generated code, it must rely upon the
`MessageId` being provided explicitly in the generated code.
The compiler now prepends all localized messages with a "metadata block"
containing the id (and the meaning and description if defined).
Note that this metadata block will also allow translation file extraction
from the compiled code - rather than relying on the legacy ViewEngine
extraction code. (This will be implemented post-v9).
Although these metadata blocks add to the initial code size, compile-time
inlining will completely remove these strings and so will not impact on
production bundle size.

Within an Angular package, it can happen that there are
entry-points which do not contain features that belong into
an `@NgModule` or need metadata files to be generated.
For example: the `cdk`, `cdk/testing` and `cdk/coercion`
entry-points. Besides other entry-points in the `cdk`
package, those entry-points do not need metadata to
be generated and no not use the `ng_module` rule.
Currently the "ng_package" rule properly picks up such
entry-points and builds bundles, does downleveling etc.
The only thing it misses is that no `package.json` files
are generated for the entry-point. This means that consumers
will not be able to use these entry-points built with "ts_library"
(except accessing the individual bundlings explicitly).
The "ng_package" rule should follow the full APF specification
for such entry-points. Partially building bundles and doing the
downleveling is confusing and a breaking issue.
The motifivation of supporting this (besides making the
rule behavior consistent; the incomplete output is not
acceptable), is that using the "ng_module" rule does
not make sense to be used for non-Angular entry-points.
Especially since it depends on Angular packages to
be specified as Bazel action inputs just to compile
vanilla TypeScript with `@angular/compiler-cli`.

If an <ng-template> contains a structural directive (for example *ngIf), Ngtsc generates extra template function with 1 template instruction call. When <ng-template> tag also contains i18n attribute on it, we generate i18nStart and i18nEnd instructions around it, which is unnecessary and breaking runtime.

This is a refactoring that moves the source code around to provide a better
platform for adding the compile-time inlining.
1. Move the global side-effect import from the primary entry-point to a
secondary entry-point @angular/localize/init.
This has two benefits: first it allows the top level entry-point to
contain tree-shakable shareable code; second it gives the side-effect
import more of an "action" oriented name, which indicates that importing
it does something tangible
2. Move all the source code into the top src folder, and import the localize
related functions into the localize/init/index.ts entry-point.
This allows the different parts of the package to share code without
a proliferation of secondary entry-points (i.e. localize/utils).
3. Avoid publicly exporting any utilities at this time - the only public
API at this point are the global `$localize` function and the two runtime
helpers `loadTranslations()` and `clearTranslations()`.
This does not mean that we will not expose additional helpers for 3rd
party tooling in the future, but it avoid us preemptively exposing
something that we might want to change in the near future.
Notes:
It is not possible to have the `$localize` code in the same Bazel package
as the rest of the code. If we did this, then the bundled `@angular/localize/init`
entry-point code contains all of the helper code, even though most of it is not used.
Equally it is not possible to have the `$localize` types (i.e. `LocalizeFn`
and `TranslateFn`) defined in the `@angular/localize/init` entry-point because
these types are needed for the runtime code, which is inside the primary
entry-point. Importing them from `@angular/localize/init` would run the
side-effect.
The solution is to have a Bazel sub-package at `//packages/localize/src/localize`
which contains these types and the `$localize` function implementation.
The primary `//packages/localize` entry-point imports the types without
any side-effect.
The secondary `//packages/localize/init` entry-point imports the `$localize`
function and attaches it to the global scope as a side-effect, without
bringing with it all the other utility functions.
BREAKING CHANGES:
The entry-points have changed:
* To attach the `$localize` function to the global scope import from
`@angular/localize/init`. Previously it was `@angular/localize`.
* To access the `loadTranslations()` and `clearTranslations()` functions,
import from `@angular/localize`. Previously it was `@angular/localize/run_time`.

In ngcc's reflection host for UMD and CommonJS bundles, custom logic is
present to resolve import details of an identifier. However, this custom
logic is unable to resolve an import for an identifier inside of
declaration files, as such files use the regular ESM import syntax.
As a consequence of this limitation, ngtsc is unable to resolve
`ModuleWithProviders` imports that are declared in an external library.
In that situation, ngtsc determines the type of the actual `NgModule`
that is imported, by looking in the library's declaration files for the
generic type argument on `ModuleWithProviders`. In this process, ngtsc
resolves the import for the `ModuleWithProviders` identifier to verify
that it is indeed the `ModuleWithProviders` type from `@angular/core`.
So, when the UMD reflection host was in use this resolution would fail,
therefore no `NgModule` type could be detected.
This commit fixes the bug by using the regular import resolution logic
in addition to the custom resolution logic that is required for UMD
and CommonJS bundles.

In ESM2015 bundles, a class with decorators may be emitted as follows:
```javascript
var MyClass_1;
let MyClass = MyClass_1 = class MyClass {};
MyClass.decorators = [/* here be decorators */];
```
Such a class has two declarations: the publicly visible `let MyClass`
and the implementation `class MyClass {}` node. In #32539 a refactoring
took place to handle such classes more consistently, however the logic
to find static properties was mistakenly kept identical to its broken
state before the refactor, by looking for static properties on the
implementation symbol (the one for `class MyClass {}`) whereas the
static properties need to be obtained from the symbol corresponding with
the `let MyClass` declaration, as that is where the `decorators`
property is assigned to in the example above.
This commit fixes the behavior by looking for static properties on the
public declaration symbol. This fixes an issue where decorators were not
found for classes that do in fact have decorators, therefore preventing
the classes from being compiled for Ivy.

In ngcc's reflection hosts for compiled JS bundles, such as ESM2015,
special care needs to be taken for classes as there may be an outer
declaration (referred to as "declaration") and an inner declaration
(referred to as "implementation") for a given class. Therefore, there
will also be two `ts.Symbol`s bound per class, and ngcc needs to switch
between those declarations and symbols depending on where certain
information can be found.
Prior to this commit, the `NgccReflectionHost` interface had methods
`getClassSymbol` and `findClassSymbols` that would return a `ts.Symbol`.
These class symbols would be used to kick off compilation of components
using ngtsc, so it is important for these symbols to correspond with the
publicly visible outer declaration of the class. However, the ESM2015
reflection host used to return the `ts.Symbol` for the inner
declaration, if the class was declared as follows:
```javascript
var MyClass = class MyClass {};
```
For the above code, `Esm2015ReflectionHost.getClassSymbol` would return
the `ts.Symbol` corresponding with the `class MyClass {}` declaration,
whereas it should have corresponded with the `var MyClass` declaration.
As a consequence, no `NgModule` could be resolved for the component, so
no components/directives would be in scope for the component. This
resulted in errors during runtime.
This commit resolves the issue by introducing a `NgccClassSymbol` that
contains references to both the outer and inner `ts.Symbol`, instead of
just a single `ts.Symbol`. This avoids the unclarity of whether a
`ts.Symbol` corresponds with the outer or inner declaration.

Previously, the docker images used on CI where specified by a tag
(`10.16` and `10.16-browsers`). Since tags are not immutable, this only
pins specific characteristics of the environment (e.g. the OS type and
the Node.js version), but not others. Especially when using a tag that
does not specify the patch version (e.g. `10.16` instead of `10.16.0`),
it is inevitable that the image will change at some point, potentially
leading to unrelated failures due to changes in the environment.
One source of such failures can be the Chrome version used in tests.
Since we install a specific ChromeDriver version (that is only
compatible with specific Chrome version ranges), unexpectedly updating
to a newer Chrome version may break the tests if the new version falls
outside the range of supported version for our pinned ChromeDriver.
Using a tag that specifies the patch version (e.g. `10.16.0`) or even
the OS version (e.g. `10.16.0-buster`) is safer (i.e. has a lower
probability of introducing the kind of breakages described above), but
is still not fully hermetic.
This commit prevents such breakages by pinning the docker images by ID.
Image IDs are based on the image's digest (SHA256) and are thus
immutable, ensuring that all CI jobs will be running on the exact same
image.

`ngcc` supports both synchronous and asynchronous execution. The default
mode when using `ngcc` programmatically (which is how `@angular/cli` is

(i.e. via the `ivy-ngcc` script), it runs in async mode.
Previously, the work would be executed in the same way in both modes.
This commit improves the performance of `ngcc` in async mode by
processing tasks in parallel on multiple processes. It uses the Node.js
built-in [`cluster` module](https://nodejs.org/api/cluster.html) to
launch a cluster of Node.js processes and take advantage of multi-core
systems.
Preliminary comparisons indicate a 1.8x to 2.6x speed improvement when

available cores, system load, etc.). Further investigation is needed to
better understand these numbers and identify potential areas of
improvement.

its only remaining property, `hasProcessedTypings`) was no longer used,

In the past, a task's processability didn't use to be known in advance.
It was possible that a task would be created and added to the queue
during the analysis phase and then later (during the compilation phase)
it would be found out that the task (i.e. the associated format
property) was not processable.
As a result, certain checks had to be delayed, until a task's processing
had started or even until all tasks had been processed. Examples of
checks that had to be delayed are:
- Whether a task can be skipped due to `compileAllFormats: false`.
- Whether there were entry-points for which no format at all was
successfully processed.
It turns out that (as made clear by the refactoring in 9537b2ff8), once
a task starts being processed it is expected to either complete
successfully (with the associated format being processed) or throw an
error (in which case the process will exit). In other words, a task's
processability is known in advance.
This commit takes advantage of this fact by moving certain checks
earlier in the process (e.g. in the analysis phase instead of the
compilation phase), which in turn allows avoiding some unnecessary work.
More specifically:
- When `compileAllFormats` is `false`, tasks are created _only_ for the
first suitable format property for each entry-point, since the rest of
the tasks would have been skipped during the compilation phase anyway.
This has the following advantages:
1. It avoids the slight overhead of generating extraneous tasks and
then starting to process them (before realizing they should be
skipped).
2. In a potential future parallel execution mode, unnecessary tasks
might start being processed at the same time as the first (useful)
task, even if their output would be later discarded, wasting
resources. Alternatively, extra logic would have to be added to
prevent this from happening. The change in this commit avoids these
issues.
- When an entry-point is not processable, an error will be thrown
upfront without having to wait for other tasks to be processed before
failing.

Previously, `ngcc`'s programmatic API would run and complete
synchronously. This was necessary for specific usecases (such as how the
`@angular/cli` invokes `ngcc` as part of the TypeScript module
resolution process), but not for others (e.g. running `ivy-ngcc` as a
`postinstall` script).
This commit adds a new option (`async`) that enables turning on
asynchronous execution. I.e. it signals that the caller is OK with the
function call to complete asynchronously, which allows `ngcc` to
potentially run in a more efficient mode.
Currently, there is no difference in the way tasks are executed in sync
vs async mode, but this change sets the ground for adding new execution
options (that require asynchronous operation), such as processing tasks
in parallel on multiple processes.
NOTE:
When using the programmatic API, the default value for `async` is
`false`, thus retaining backwards compatibility.
When running `ngcc` from the command line (i.e. via the `ivy-ngcc`
script), it runs in async mode (to be able to take advantage of future
optimizations), but that is transparent to the caller.

Prior to this commit, listeners order was not preserved in case we coalesce them to avoid triggering unnecessary change detection cycles. For performance reasons we were attaching listeners to existing events at head (always using first listener as an anchor), to avoid going through the list, thus breaking the order in which listeners are registered. In some scenarios this order might be important (for example with `ngModelChange` and `input` listeners), so this commit updates the logic to put new listeners at the end of the list. In order to avoid performance implications, we keep a pointer to the last listener in the list, so adding a new listener takes constant amount of time.

Fixes an issue where Ivy incorrectly inserts items in the beginning of an `ngFor`, if the `ngFor` is set on an `ng-container`. The issue comes from the fact that we choose the `ng-container` comment node as the anchor point before which to insert the content, however the node might be after any of the nodes inside the container. These changes switch to picking out the first node inside of the container instead.

Prior to this commit, complex expressions (that require additional statements to be generated) were handled incorrectly in case they were used in attributes annotated with i18n flags.

This commit updated the logic to use the `convertPropertyBinding`, which contains the necessary code to append extra statements.

The Table of Contents (ToC) is auto-generated based on the content of
heading elements on the page. At the same time, anchor links are
auto-generated and added to each heading element. Note that the Material
Icons used for the anchor icon make use of ligatures, which means that
the icons are specified by using their textual name as text content of
the icon element. As a result, the name of the icon is included in the
parent element's `textContent`.
Previously, the `TocService` used to strip off these anchor elements
when generating the content of ToC items, but not when generating the
content of their tooltips. Thus, tooltips for ToC items would
confusingly include a `link` suffix (`link` is the textual name of the
icon used in heading anchor links).
This commit fixes this by deriving the tooltip content from the
transformed text content (which already has anchor links stripped off),
instead of from the original heading content.

Previously, when the ServiceWorker entered a degraded mode
(`EXISTING_CLIENTS_ONLY` or `SAFE_MODE`) it would remain in that mode
for the rest of the lifetime of ServiceWorker instance. Note that
ServiceWorkers are stopped by the browser after a certain period of
inactivity and a new instance is created as soon as the ServiceWorker
needs to handle an event (such as a request from the page). Those new
instances would start from the `NORMAL` mode.
The reason for this behavior is to err on the side of caution: If we
can't be sure why the ServiceWorker entered the degraded mode, it is
risky to try recovering on the same instance and might lead to
unexpected behavior.
However, it turns out that the `EXISTING_CLIENTS_ONLY` mode can only be
a result of some error happening with the latest version (e.g. a hash
mismatch in the manifest). Therefore, it is safe to recover from that
mode once a new, valid update is successfully installed and to start
accepting new clients.
This commit ensures that the mode is set back to `NORMAL`, when (a) an
update is successfully installed and (b) the current mode is
`EXISTING_CLIENTS_ONLY`.
Besides making the behavior more predictable (instead of relying on the
browser to decide when to terminate the current ServiceWorker instance
and create a new one), this change can also improve the developer
experience:
When people notice the error during debugging and fix it by deploying a
new version (either to production or locally), it is confusing that the
ServiceWorker will fetch and install the update (as seen by the requests
in the Network panel in DevTools) but not serve it to clients. With this
change, the update will be served to new clients as soon as it is
installed.

PR Close#31609
This commit changes the Angular compiler (ivy-only) to generate `$localize`
tagged strings for component templates that use `i18n` attributes.
BREAKING CHANGE
Since `$localize` is a global function, it must be included in any applications
that use i18n. This is achieved by importing the `@angular/localize` package
into an appropriate bundle, where it will be executed before the renderer
needs to call `$localize`. For CLI based projects, this is best done in
the `polyfills.ts` file.

import '@angular/localize';

Previously, the emulated Windows mode would normalize rooted paths to

When ngcc is called for a specific entry-point, it has to determine
which dependencies to transitively process. To accomplish this, ngcc
traverses the full import graph of the entry-points it encounters, for
which it uses a dependency host to find all module imports. Since
imports look different in the various bundle formats ngcc supports, a
specific dependency host is used depending on the information provided
in an entry-points `package.json` file. If there's not enough
information in the `package.json` file for ngcc to be able to determine
which dependency host to use, ngcc would fail with an error.
If, however, the entry-point is not compiled by Angular, it is not
necessary to process any of its dependencies. None of them can have
been compiled by Angular so ngcc does not need to know about them.
Therefore, this commit changes the behavior to avoid recursing into
dependencies of entry-points that are not compiled by Angular.
In particular, this fixes an issue for packages that have dependencies
on the `date-fns` package. This package has various secondary
entry-points that have a `package.json` file only containing a `typings`
field, without providing additional fields for ngcc to know which
dependency host to use. By not needing a dependency host at all, the
error is avoided.

In ngc is was valid to set the "flatModuleOutFile" option to "null". This is sometimes
necessary if a tsconfig extends from another one but the "fatModuleOutFile" option
needs to be unset (note that "undefined" does not exist as value in JSON)
Now if ngtsc is used to compile the project, ngtsc will fail with an error because it
tries to do string manipulation on the "flatModuleOutFile". This happens because
ngtsc only skips flat module indices if the option is set to "undefined".
Since this is not compatible with what was supported in ngc and such exceptions
should be avoided, the flat module check is now aligned with ngc.

Angular hooks come after 2 flavours:
- init hooks (OnInit, AfterContentInit, AfterViewInit);
- check hooks (OnChanges, DoChanges, AfterContentChecked, AfterViewChecked).
We need to do more processing for init hooks to ensure that those hooks
are run once and only once for a given directive (even in case of errors).
As soon as all init hooks execute to completion we are only left with the
checks to execute.
It turns out that keeping track of the remaining init hooks to execute is
rather expensive (multiple LView flags reads, writes and checks). But we can
observe that non of this tracking is needed as soon as all init hooks are
completed.
This PR takes advantage of the above observations and splits hooks processing
functions into:
- init-specific (slower but less common);
- check-specific (faster and more common).
NOTE: there is code duplication in this PR and it is left like this intentinally:
hand-inlining this perf-critical code makes the view refresh process substentially

Currently, it's not possible to tree-shake away the
coordination layer between HammerJS and Angular's
EventManager. This means that you get the HammerJS
support code in your production bundle whether or
not you actually use the library.
This commit removes the Hammer providers from the
default platform_browser providers list and instead
provides them as part of a `HammerModule`. Apps on
Ivy just need to import the `HammerModule` at root
to turn on Hammer support. Otherwise all Hammer code
will tree-shake away. View Engine apps will require
no change.
BREAKING CHANGE
Previously, in Ivy applications, Hammer providers
were included by default. With this commit, apps
that want Hammer support must import `HammerModule`
in their root module.

Historically, the Angular Compiler has produced both native TypeScript
diagnostics (called ts.Diagnostics) and its own internal Diagnostic format
(called an api.Diagnostic). This was done because TypeScript ts.Diagnostics
cannot be produced for files not in the ts.Program, and template type-
checking diagnostics are naturally produced for external .html template
files.
This design isn't optimal for several reasons:
1) Downstream tooling (such as the CLI) must support multiple formats of
diagnostics, adding to the maintenance burden.
2) ts.Diagnostics have gotten a lot better in recent releases, with support
for suggested changes, highlighting of the code in question, etc. None of
these changes have been of any benefit for api.Diagnostics, which have
continued to be reported in a very primitive fashion.
3) A future plugin model will not support anything but ts.Diagnostics, so
generating api.Diagnostics is a blocker for ngtsc-as-a-plugin.
4) The split complicates both the typings and the testing of ngtsc.
To fix this issue, this commit changes template type-checking to produce
ts.Diagnostics instead. Instead of reporting a special kind of diagnostic
for external template files, errors in a template are always reported in
a ts.Diagnostic that highlights the portion of the template which contains
the error. When this template text is distinct from the source .ts file
(for example, when the template is parsed from an external resource file),
additional contextual information links the error back to the originating
component.
A template error can thus be reported in 3 separate ways, depending on how
the template was configured:
1) For inline template strings which can be directly mapped to offsets in
the TS code, ts.Diagnostics point to real ranges in the source.
This is the case if an inline template is used with a string literal or a
"no-substitution" string. For example:
```typescript
@Component({..., template: `
<p>Bar: {{baz}}</p>
`})
export class TestCmp {
bar: string;
}
```
The above template contains an error (no 'baz' property of `TestCmp`). The
error produced by TS will look like:
```
<p>Bar: {{baz}}</p>
~~~
test.ts:2:11 - error TS2339: Property 'baz' does not exist on type 'TestCmp'. Did you mean 'bar'?
```
2) For template strings which cannot be directly mapped to offsets in the
TS code, a logical offset into the template string will be included in
the error message. For example:
```typescript
const SOME_TEMPLATE = '<p>Bar: {{baz}}</p>';
@Component({..., template: SOME_TEMPLATE})
export class TestCmp {
bar: string;
}
```
Because the template is a reference to another variable and is not an
inline string constant, the compiler will not be able to use "absolute"
positions when parsing the template. As a result, errors will report logical
offsets into the template string:
```
<p>Bar: {{baz}}</p>
~~~
test.ts (TestCmp template):2:15 - error TS2339: Property 'baz' does not exist on type 'TestCmp'.
test.ts:3:28
@Component({..., template: TEMPLATE})
~~~~~~~~
Error occurs in the template of component TestCmp.
```
This error message uses logical offsets into the template string, and also
gives a reference to the `TEMPLATE` expression from which the template was
parsed. This helps in locating the component which contains the error.
3) For external templates (templateUrl), the error message is delivered
within the HTML template file (testcmp.html) instead, and additional
information contextualizes the error on the templateUrl expression from
which the template file was determined:
```
<p>Bar: {{baz}}</p>
~~~
testcmp.html:2:15 - error TS2339: Property 'baz' does not exist on type 'TestCmp'.
test.ts:10:31
@Component({..., templateUrl: './testcmp.html'})
~~~~~~~~~~~~~~~~
Error occurs in the template of component TestCmp.

Previously, `ngcc` assumed that if a format property was defined in
`package.json` it would point to a valid format-path (i.e. a file that
is an entry-point for a specific format). This is generally the case,
except if a format property is set to a non-string value (such as
`package.json`) - either directly in the `package.json` (which is unusual)
or in ngcc.config.js (which is a valid usecase, when one wants a
format property to be ignored by `ngcc`).
For example, the following config file would cause `ngcc` to throw:
```
module.exports = {

similarly to how it worked in view engine.
Due to the planned refactorings which ensure that `@Directive`, `@Component`
and `@Pipe` also have a factory definition, this migration is no longer
needed for Ivy. Additionally since it is already disabled (due to

During the dependency analysis phase of ngcc, imports are resolved to
files on disk according to certain module resolution rules. Since module
specifiers are typically missing extensions, or can refer to index.js
barrel files within a directory, the module resolver attempts several
postfixes when searching for a module import on disk. Module specifiers
that already include an extension, however, would fail to be resolved as
ngcc's module resolver failed to check the location on disk without
adding any postfixes.
Closes#32097
PR Close#32181
During the recursive processing of dependencies, ngcc resolves the
requested file to an actual location on disk, by testing various
extensions. For recursive calls however, the path is known to have been
resolved in the module resolver. Therefore, it is safe to move the path
resolution to the initial caller into the recursive process.
Note that this is not expected to improve the performance of ngcc, as
the call to `resolveFileWithPostfixes` is known to succeed immediately,
as the provided path is known to exist without needing to add any
postfixes. Furthermore, the FileSystem caches whether files exist, so
the additional check that we used to do was cheap.

ngcc needs to solve a unique problem when compiling typings for an
entrypoint: it must resolve a declaration within a .js file to its
representation in a .d.ts file. Since such .d.ts files can be used in deep
imports without ever being referenced from the "root" .d.ts, it's not enough
to simply match exported types to the root .d.ts. ngcc must build an index
of all .d.ts files.
Previously, this operation had a bug: it scanned all .d.ts files in the
.d.ts program, not only those within the package. Thus, if a class in the
program happened to share a name with a class exported from a dependency's
.d.ts, ngcc might accidentally modify the wrong .d.ts file, causing a
variety of issues downstream.
To fix this issue, ngcc's .d.ts scanner now limits the .d.ts files it
indexes to only those declared in the current package.

One of the compiler's tasks is to enumerate the exports of a given ES
module. This can happen for example to resolve `foo.bar` where `foo` is a
namespace import:
```typescript
import * as foo from './foo';
@NgModule({
directives: [foo.DIRECTIVES],
})
```
In this case, the compiler must enumerate the exports of `foo.ts` in order
to evaluate the expression `foo.DIRECTIVES`.
When this operation occurs under ngcc, it must deal with the different
module formats and types of exports that occur. In commonjs code, a problem
arises when certain exports are downleveled.
```typescript
export const DIRECTIVES = [
FooDir,
BarDir,
];
```
can be downleveled to:
```javascript
exports.DIRECTIVES = [
FooDir,
BarDir,
```
Previously, ngtsc and ngcc expected that any export would have an associated
`ts.Declaration` node. `export class`, `export function`, etc. all retain
`ts.Declaration`s even when downleveled. But the `export const` construct
above does not. Therefore, ngcc would not detect `DIRECTIVES` as an export
of `foo.ts`, and the evaluation of `foo.DIRECTIVES` would therefore fail.
To solve this problem, the core concept of an exported `Declaration`
according to the `ReflectionHost` API is split into a `ConcreteDeclaration`
which has a `ts.Declaration`, and an `InlineDeclaration` which instead has
a `ts.Expression`. Differentiating between these allows ngcc to return an
`InlineDeclaration` for `DIRECTIVES` and correctly keep track of this
export.

In VE the `Sanitizer` is always available in `BrowserModule` because the VE retrieves it using injection.
In Ivy the injection is optional and we have instructions instead of component definition arrays. The implication of this is that in Ivy the instructions can pull in the sanitizer only when they are working with a property which is known to be unsafe. Because the Injection is optional this works even if no Sanitizer is present. So in Ivy we first use the sanitizer which is pulled in by the instruction, unless one is available through the `Injector` then we use that one instead.
This PR does few things:
1) It makes `Sanitizer` optional in Ivy.
2) It makes `DomSanitizer` tree shakable.

In Angular today, the following pattern works:
```typescript
export class BaseDir {
constructor(@Inject(ViewContainerRef) protected vcr: ViewContainerRef) {}
}
@Directive({
selector: '[child]',
})
export class ChildDir extends BaseDir {
// constructor inherited from BaseDir
}
```
A decorated child class can inherit a constructor from an undecorated base
class, so long as the base class has metadata of its own (for JIT mode).
This pattern works regardless of metadata in AOT.
In Angular Ivy, this pattern does not work: without the @Directive
annotation identifying the base class as a directive, information about its
constructor parameters will not be captured by the Ivy compiler. This is a
result of Ivy's locality principle, which is the basis behind a number of
compilation optimizations.
As a solution, @Directive() without a selector will be interpreted as a
"directive base class" annotation. Such a directive cannot be declared in an
NgModule, but can be inherited from. To implement this, a few changes are
made to the ngc compiler:
* the error for a selector-less directive is now generated when an NgModule
declaring it is processed, not when the directive itself is processed.
* selector-less directives are not tracked along with other directives in
the compiler, preventing other errors (like their absence in an NgModule)
from being generated from them.

Here `formControlName` receives a number whereas its input type is a string.
This is fine for VE and `fullTemplateTypeCheck`, but not for Ivy which does a more thorough type checking on inputs with `fullTemplateTypeCheck` enabled and throws `Type 'number' is not assignable to type 'string'`. It is fixable by using `formControlName="{{i}}"` but you have to know the difference between `a="{{b}}"` and `[a]="b"` and change it all over the application codebase.

- It would validate the rest of the commit message header as any other

However, fixup commits are special in that they need to exactly match an

not matching their original commit for several reasons (e.g. accidental
typo, changing the original commit message, etc.).

A decorated child class can inherit a constructor from an undecorated base
class, so long as the base class has metadata of its own (for JIT mode).
This pattern works regardless of metadata in AOT.
In Angular Ivy, this pattern does not work: without the @Directive
annotation identifying the base class as a directive, information about its
constructor parameters will not be captured by the Ivy compiler. This is a
result of Ivy's locality principle, which is the basis behind a number of
compilation optimizations.
As a solution, @Directive() without a selector will be interpreted as a
"directive base class" annotation. Such a directive cannot be declared in an
NgModule, but can be inherited from. To implement this, a few changes are
made to the ngc compiler:
* the error for a selector-less directive is now generated when an NgModule
declaring it is processed, not when the directive itself is processed.
* selector-less directives are not tracked along with other directives in
the compiler, preventing other errors (like their absence in an NgModule)
from being generated from them.

PR #29473 changed the docs to use a string as the input value of `formControlName`, as it used to only accept a string.
This has been changed, and `formControlName` now accepts a string or a number, so the example in the docs can use a binding as they used to.
PR Close#30606
This commit relaxes the type of the `formControlName` input to accept both a `string` and a `number`.
Currently, when using a `FormArray`, most templates look like:
```
<div formArrayName="tags">
<div *ngFor="let tag of tagsArray.controls; index as i">
<input [formControlName]="i">
</div>
</div>
```
Here `formControlName` receives a number whereas its input type is a string.
This is fine for VE and `fullTemplateTypeCheck`, but not for Ivy which does a more thorough type checking on inputs with `fullTemplateTypeCheck` enabled and throws `Type 'number' is not assignable to type 'string'`. It is fixable by using `formControlName="{{i}}"` but you have to know the difference between `a="{{b}}"` and `[a]="b"` and change it all over the application codebase. This commit allows the existing code to still type-check.

Examples for testing are designed specifically to run in StackBlitz and
are not regular cli projects (e.g. their `main.ts` files may load and run
tests instead of bootstrapping an app). They are not intended to be
downloaded and built/run locally using the cli.
In order to avoid confusing users, this commit removes the download links
from the guide. If desired, the projects can still be exported locally
via StackBlitz's UI.

Now that the Angular LS is a proper tsserver plugin, it does not make
sense for it to maintain its own language service API.
This is part one of the effort to remove our custom LanguageService
interface.
This interface is cumbersome because we have to do two transformations:
ng def -> ts def -> lsp definition
The TS LS interface is more comprehensive, so this allows the Angular LS
to return more information.

Publishing of NGCC packages should not be allowed. It is easy for a user to publish an NGCC'd version of a library they have workspace libraries which are being used in a workspace application.
If a users builds a library and afterwards the application, the library will be transformed with NGCC and since NGCC taints the distributed files that should be published.
With this change we use the npm/yarn `prepublishOnly` hook to display and error and abort the process with a non zero error code when a user tries to publish an NGCC version of the package.

Previously, when run with `createNewEntryPointFormats: true`, `ngcc`
would only update `package.json` with the new entry-point for the first
format property that mapped to a format-path. Subsequent properties
mapping to the same format-path would be detected as processed and not
have their new entry-point format recorded in `package.json`.
This commit fixes this by ensuring `package.json` is updated for all
matching format properties, when writing an `EntryPointBundle`.
PR Close#32052
Remove the `formatProperty` property from the `EntryPointBundle`
interface, because the property is not directly related to that type.

This change basically moves some checks to happen up front and ensures
we don't try to process any more properties than we absolutely need.
(The properties would not be processed before either, but we would
consider them, before finding out that they have already been processed
or that they do not exist in the entry-point's `package.json`.)
This change should make no difference in the work done by `ngcc`, but it
transforms the code in a way that makes the actual work known earlier,
thus making it easier to parallelize the processing of each property in
the future.

In commit 7b55ba58b (part of PR #29092), the implementation of
`makeEntryPointBundle()` was changed such that it now always return
`EntryPointBundle` (and not `null`).
However, the return type was not updated and as result we continued to
unnecessarily handle `null` as a potential return value in some places.
This commit fixes the return type to reflect the implementation and
removes the redundant code that was dealing with `null`.

ngcc analyzes the dependency structure of the entrypoints it needs to
process, as the compilation of entrypoints is ordering sensitive: any
dependent upon entrypoint must be compiled before its dependees. As part
of the analysis of the dependency graph, it is detected when a
dependency of entrypoint is not installed, in which case that entrypoint
will be marked as ignored.
For libraries that work with Angular Universal to run in NodeJS, imports
into builtin NodeJS modules can be present. ngcc's dependency analyzer
can only resolve imports within the TypeScript compilation, which
builtin modules are not part of. Therefore, such imports would
erroneously cause the entrypoint to become ignored.
This commit fixes the problem by taking the NodeJS builtins into account
when dealing with missing imports.

The `setup-local` npm script uses `NgPackagesInstaller` to replace the
Angular packages with the locally built ones. Previously, it would (a)
assume that the packages were built and (b) it would do anything if the
currently installed versions already correspond to locally built
packages (even if not the latest version).
This could lead to all sorts of errors, such as:
- Confusing error messages, `dist/packages-dist/` was missing.
- Using outdated build artifacts from `dist/packages-dist/` without a
warning.
- Not installing the latest locally built packages, because the ones
installed already corresponded to locally built (but older) ones.
This commit fixes these issues by ensuring that:
- The local packages are always built before being used by
`NgPackagesInstaller`.
- The local packages are installed, even if the ones install already
correspond to local packages.
NOTE: Special `*-ci` scripts are introduced (for use on CI) that skip
building the local packages, since that step would have been taken
care of (in a more efficient way) in a previous CI step.
PR Close#31985
Previously, when `NgPackagesInstaller` needed to install the local
Angular packages to a project, it assumed the `dist/packages-dist/`
would exist and contain up-to-date built packages. I.e. it was up to the
user to have built the packages first (by running the appropriate
script).
However, many people not familiar with the `aio/` infrastructure assumed
that `yarn build-local` or `yarn build-with-ivy` would take care of all
the necessary steps.
To avoid getting confusing errors (or worse yet, using outdated local
packages), `NgPackagesInstaller` now has an option to build the packages
before using them.
One caveat is that the build script does not currently work on Windows,
so a warning is printed instead, letting the user know they need to
(somehow) take care of it themselves.
NOTE 1: Since the build script is using bazel, running it should not be
expensive if the directory is up-to-date (i.e. no changes have
been made to source code after the last build).
NOTE 2: This commit adds support for `--build-packages`, but does not
change the default behavior (not building the packages). It will
be turned on in a subsequent commit.
PR Close#31985
Previously, `ngcc` would avoid processing a `formatPath` that a property
in `package.json` mapped to, if either the _property_ was marked as
processed or the `formatPath` (i.e. the file(s)) was processed in the
same `ngcc` run (since the `compiledFormats` set was not persisted
across runs).
This could lead in a situation where a `formatPath` would be compiled
twice (if for example properties `a` and `b` both mapped to the same
`formatPath` and one would run `ngcc` for property `a` and then `b`).
This commit fixes it by ensuring that as soon as a `formatPath` has been
processed all corresponding properties are marked as processed (which
persists across `ngcc` runs).
PR Close#32003
Previously, when `ngcc` was called with `compileAllFormats === false`
(i.e. how `@angular/cli` calls it), it would not attempt to process
more properties, once the first was successfully processed. However, it
_would_ continue looping over them and perform some unnecessary
operations, such as:
- Determining the format each property maps to (which can be an
expensive operation for some properties mapping to either UMD or
CommonJS).
- Checking whether each property has been processed (which involves
checking whether any property has been processed with a different
version of `ngcc` each time).
- Potentially marking properties as processed (which involves a
file-write operation).
This commit avoids the unnecessary operations by entirely skipping
subsequent properties, once the first one has been successfully
processed. While this theoretically improves performance, it is not
expected to have any noticeable impact in practice, since the list of
`propertiesToConsider` is typically small and the most expensive
operation (marking a property as processed) has low likelihood of
happening (plus these operations are a tiny fraction of `ngcc`'s work).
PR Close#32003
Previously, when `ngcc` needed to mark multiple properties as processed
(e.g. a processed format property and `typings` or all supported
properties for a non-Angular entry-point), it would update each one
separately and write the file to disk multiple times.
This commit changes this, so that multiple properties can be updated at
once with one file-write operation. While this theoretically improves
performance (reducing the I/O operations), it is not expected to have
any noticeable impact in practice, since these operations are a tiny
fraction of `ngcc`'s work.
This change will be useful for a subsequent change to mark all
properties that map to the same `formatPath` as processed, once it is
processed the first time.

This folder contains configuration for the [CodeFresh](<https://codefresh.io/>) based CI checks for this repository.
## The build pipeline
CodeFresh uses a several pipeline for each repository. The `codefresh.yml` file defines pipeline [build steps](https://codefresh.io/docs/docs/configure-ci-cd-pipeline/introduction-to-codefresh-pipelines/) for this repository.
Run results can be seen in the GitHub checks interface and in the [public pipeline](https://g.codefresh.io/public/accounts/angular/pipelines/angular/angular/angular)
Although most configuration is done via `pipeline.yml`, some options are only available in the online [pipeline settings](https://g.codefresh.io/pipelines/angular/services?repoOwner=angular&repoName=angular&project=angular%2Fangular&context=github&serviceName=angular%2Fangular), which needs a login to access.
## Caretaker
CodeFresh status can be found at <http://status.codefresh.io/>.
Issues related to the CodeFresh setup should be escalated to the Tools Team via the current caretaker, followed by Alex Eagle and Filipe Silva.
## Rollout strategy
Currently it is only used for tests on Windows platforms, on the master branch, and without pushing user-facing reports. It's only possible to see current builds in the [public pipeline dashboard](https://g.codefresh.io/public/accounts/angular/pipelines/angular/angular/angular).
After a week or two of running like this, we should reassess how stable and reliable it is.
