Kara Erickson 64fd0d6db9 refactor(core): rename ngComponentDef to ɵcmp (#33088)
Component defs are not considered public API, so the property
that contains them should be prefixed with Angular's marker
for "private" ('ɵ') to discourage apps from relying on def
APIs directly.

This commit adds the prefix and shortens the name from
`ngComponentDef` to `cmp`. This is because property names
cannot be minified by Uglify without turning on property
mangling (which most apps have turned off) and are thus
size-sensitive.

Note that the other "defs" (ngDirectiveDef, etc) will be
prefixed and shortened in follow-up PRs, in an attempt to
limit how large and conflict-y this change is.

Pete Bacon Darwin f640a4a494 fix(ivy): i18n - turn on legacy message-id support by default (#33053)
For v9 we want the migration to the new i18n to be as
simple as possible.

Previously the developer had to positively choose to use
legacy messsage id support in the case that their translation
files had not been migrated to the new format by setting the
`legacyMessageIdFormat` option in tsconfig.json to the format
of their translation files.

Now this setting has been changed to `enableI18nLegacyMessageFormat`
as is a boolean that defaults to `true`. The format is then read from
the `i18nInFormat` option, which was previously used to trigger translations
in the pre-ivy angular compiler.

crisbeto d5b87d32b0 perf(ivy): move attributes array into component def (#32798)
Currently Ivy stores the element attributes into an array above the component def and passes it into the relevant instructions, however the problem is that upon minification the array will get a unique name which won't compress very well. These changes move the attributes array into the component def and pass in the index into the instructions instead.

Before:
```
const _c0 = ['foo', 'bar'];

SomeComp.ngComponentDef = defineComponent({
  template: function() {
    element(0, 'div', _c0);
  }
});
```

After:
```
SomeComp.ngComponentDef = defineComponent({
  consts: [['foo', 'bar']],
  template: function() {
    element(0, 'div', 0);
  }
});
```

A couple of cases that this PR doesn't handle:
* Template references are still in a separate array.
* i18n attributes are still in a separate array.

Keen Yee Liau adb562bca6 fix(language-service): create StaticReflector once only (#32543)
The creation of StaticReflector in createMetadataResolver() is a very expensive operation because it involves numerous module resolutions.
To make matter worse, since the API of the Reflector does not provide the ability to invalidate its internal caches, it has to be destroyed and recreated on *every* program change.
This has a HUGE impact on performance.

Pete Bacon Darwin bcbf3e4123 feat(ivy): i18n - render legacy message ids in `$localize` if requested (#32937)
The `$localize` library uses a new message digest function for
computing message ids. This means that translations in legacy
translation files will no longer match the message ids in the code
and so will not be translated.

This commit adds the ability to specify the format of your legacy
translation files, so that the appropriate message id can be rendered
in the `$localize` tagged strings. This results in larger code size
and requires that all translations are in the legacy format.

Going forward the developer should migrate their translation files
to use the new message id format.

Pete Bacon Darwin 9188751adc fix(ivy): i18n - do not render message ids unnecessarily (#32867)
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.

crisbeto 4e35e348af refactor(ivy): generate ngFactoryDef for injectables (#32433)
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)();
}
```

Andrew Kushnir 966c2a326a fix(ivy): include `ngProjectAs` into attributes array (#32784)
Prior to this commit, the `ngProjectAs` attribute was only included with a special flag and in a parsed format. As a result, projected node was missing `ngProjectAs` attribute as well as other attributes added after `ngProjectAs` one. This is problematic since app code might rely on the presence of `ngProjectAs` attribute (for example in CSS). This commit fixes the problem by including `ngProjectAs` into attributes array as a regular attribute and also makes sure that the parsed version of the `ngProjectAs` attribute with a special marker is added after regular attributes (thus we set them correctly at runtime). This change also aligns View Engine and Ivy behavior.

Pete Bacon Darwin b741a1c3e7 fix(ivy): i18n - update the compiler to output `MessageId`s (#32594)
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.

BREAKING CHANGE

Since `$localize` is a global function, it must be included in any applications

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';

file or another suitable script file.

Alex Rickabaugh 4055150910 feat(compiler): allow selector-less directives as base classes (#31379)
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.

Pete Bacon Darwin 0ddf0c4895 fix(compiler): do not remove whitespace wrapping i18n expansions (#31962)
Similar to interpolation, we do not want to completely remove whitespace
nodes that are siblings of an expansion.

For example, the following template

```html
<div>
  <strong>items left<strong> {count, plural, =1 {item} other {items}}
</div>
```

was being collapsed to

```html
<div><strong>items left<strong>{count, plural, =1 {item} other {items}}</div>
```

which results in the text looking like

```
items left4
```

instead it should be collapsed to

```html
<div><strong>items left<strong> {count, plural, =1 {item} other {items}}</div>
```

which results in the text looking like

```
items left 4
```

the generated ids to change, so there is no breaking change here.**

Alex Rickabaugh f90c7a9df0 feat(compiler): allow selector-less directives as base classes (#31379)
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.

This commit updates the `_clone` function of the `_ApplySourceSpanTransformer` class, where the for-in loop was used, resulting in copying from prototype to own properties, thus consuming more memory. Prior to NodeJS 12 (V8 versions before 7.4) there was an optimization that was improving the situation and since that logic was removed in favor of other optimizations, the situation with memory consumption caused by the for-in loop got worse.

crisbeto 0aff4a6919 fix(ivy): incorrect ChangeDetectorRef injected into pipes used in component inputs (#31438)
When injecting a `ChangeDetectorRef` into a pipe, the expected result is that the ref will be tied to the component in which the pipe is being used. This works for most cases, however when a pipe is used inside a property binding of a component (see test case as an example), the current `TNode` is pointing to component's host so we end up injecting the inner component's view. These changes fix the issue by only looking up the component view of the `TNode` if the `TNode` is a parent.

Ayaz Hafiz f65db20c6d feat(ivy): record absolute position of template expressions (#31391)
Currently, template expressions and statements have their location
recorded relative to the HTML element they are in, with no handle to
absolute location in a source file except for a line/column location.
However, the line/column location is also not entirely accurate, as it
points an entire semantic expression, and not necessarily the start of
an expression recorded by the expression parser.

To support record of the source code expressions originate from, add a
new `sourceSpan` field to `ASTWithSource` that records the absolute byte
offset of an expression within a source code.

Fixes Ivy matching directives against attribute bindings (e.g. `[attr.some-directive]="foo"`). Works by excluding attribute bindings from the attributes array during compilation. This has the added benefit of generating less code.

**Note:** My initial approach to implementing this was to have a different marker for attribute bindings so that they can be ignored when matching directives, however as I was implementing it I realized that the attributes in that array were only used for directive matching (as far as I could tell).

crisbeto 40d785f0a0 perf(ivy): avoid generating extra parameters for host property bindings (#31550)
Currently we reuse the same instruction both for regular property bindings and property bindings on the `host`. The only difference between the two is that when it's on the host we shouldn't support inputs. We have an optional parameter called `nativeOnly` which is used to differentiate the two, however since `nativeOnly` is preceeded by another optional parameter (`sanitizer`), we have to generate two extra parameters for each host property bindings every time (e.g. `property('someProp', 'someValue', null, true)`).

These changes add a new instruction called `hostProperty` which avoids the need for the two parameters by removing `nativeOnly` which is always set and it allows us to omit `sanitizer` when it isn't being used.

These changes also remove the `nativeOnly` parameter from the `updateSyntheticHostBinding` instruction, because it's only generated for host elements which means that we can assume that its value will always be `true`.

At runtime, however, `styleMap` would set invalid styles that look like `<div style="0:w;1:i;2:d;3:t;4:h;5::;7:1;">`.

There's no build time dependency from @angular/core to @angular/compiler,
so core can't directly refer to compiler types. To overcome this limitation,
there's a facade layer defined in the compiler and duplicated in core,

There's a testcase in the compiler that verifies that all such facade types
are compatible across core and compiler, such that the core types can't get

Paul Gschwendtner 58be2ff884 fix(ivy): unable to bind to implicit receiver in embedded views (#30897)
To provide some context: The implicit receiver is part of the
parsed Angular template AST. Any property reads in bindings,
interpolations etc. read from a given object (usually the component
instance). In that case there is an _implicit_ receiver which can also
be specified explicitly by just using `this`.

e.g.

```html
<ng-template>{{this.myProperty}}</ng-template>
```

This works as expected in Ivy and View Engine, but breaks in case the
implicit receiver is not used for property reads. For example:

```html
<my-dir [myFn]="greetFn.bind(this)"></my-dir>
```

In that case the `this` will not be properly translated into the generated
template function code because the Ivy compiler currently always treats
the `ctx` variable as the implicit receiver. This is **not correct** and breaks
compatibility with View Engine. Rather we need to ensure that we retrieve
the root context for the standalone implicit receiver similar to how it works
for property reads (as seen in the example above with `this.myProperty`)

Note that this requires some small changes to the `expression_converter`
because we only want to generate the `eenextContent()` instruction if the
implicit receiver is _actually_ used/needed. View Engine determines if that is the case by recursively walking through the converted output AST and
checking for usages of the `o.variable('_co')` variable ([see here][ve_check]). This would work too for Ivy, but involves most likely more code duplication
since templates are isolated in different functions and it another pass
through the output AST for every template expression.

If a projection was removed from a translation, then its nodes won't be projected at all.

reserved projection slots which appear when using the default
selector multiple times (as seen above).

In order to fix this issue, the Ivy compiler now passes all
projection slots to the `projectionDef` instruction. Meaning that
there can be multiple projection slots with the same wildcard
selector. This allows multi-slot projection as seen in the
example above, and it also allows us to match the multi-slot node
projection order from View Engine (to avoid breaking changes).

It basically ensures that Ivy fully matches the View Engine behavior
except of a very small edge case that has already been discussed
in FW-886 (with the conclusion of working as intended).

Olivier Combe 53c6b78c51 feat(ivy): add `AttributeMarker.I18n` for i18n attributes (#30402)
`i18nAttributes` instructions always occur after the element instruction. This means that we need to treat `i18n-` attributes differently.

Alex Rickabaugh b61784948a fix(ivy): template inputs/outputs should not be bound in template scope (#30669)
The R3TargetBinder "binds" an Angular template AST, computing semantic
information regarding the template and making it accessible.

One of the binding passes previously had a bug, where for the following
template:

<div *ngIf="foo as foo"></div>

which desugars to:

<ng-template ngIf [ngIf]="foo" let-foo="ngIf">
  <div></div>
</ng-template>

would have the `[ngIf]` binding processed twice - in both the scope which
contains the `<ng-template>` and the scope inside the template. The bug
arises because during the latter, `foo` is a variable defined by `let-foo`,
and so the R3TargetBinder would incorrectly learn that `foo` inside `[ngIf]`
maps to that variable.

This commit fixes the bug by only processing inputs, outputs, and
templateAttrs from `Template`s in the outer scope.

This commit makes the static flag on @ViewChild and @ContentChild required.

BREAKING CHANGE:

In Angular version 8, it's required that all @ViewChild and @ContentChild

8.0 developers are required to explicitly specify which behavior is wanted.

Alex Rickabaugh bea85ffe9c fix(ivy): match microsyntax template directives correctly (#29698)
Previously, Template.templateAttrs was introduced to capture attribute
bindings which originated from microsyntax (e.g. bindings in *ngFor="...").
This means that a Template node can have two different structures, depending
on whether it originated from microsyntax or from a literal <ng-template>.

In the literal case, the node behaves much like an Element node, it has
attributes, inputs, and outputs which determine which directives apply.
In the microsyntax case, though, only the templateAttrs should be used
to determine which directives apply.

Previously, both the t2_binder and the TemplateDefinitionBuilder were using
the wrong set of attributes to match directives - combining the attributes,
inputs, outputs, and templateAttrs of the Template node regardless of its
origin. In the TDB's case this wasn't a problem, since the TDB collects a
global Set of directives used in the template, so it didn't matter whether
the directive was also recognized on the <ng-template>. t2_binder's API
distinguishes between directives on specific nodes, though, so it's more
sensitive to mismatching.

In particular, this showed up as an assertion failure in template type-
checking in certain cases, when a directive was accidentally matched on
a microsyntax template element and also had a binding which referenced a
variable declared in the microsyntax. This resulted in the type-checker
attempting to generate a reference to a variable that didn't exist in that
scope.

The fix is to distinguish between the two cases and select the appropriate
set of attributes to match on accordingly.

Testing strategy: tested in the t2_binder tests.

Alex Rickabaugh 073d258deb feat(ivy): template type-checking for '#' references in templates (#29698)
Previously the template type-checking engine processed templates in a linear
manner, and could not handle '#' references within a template. One reason
for this is that '#' references are non-linear - a reference can be used
before its declaration. Consider the template:

```html
{{ref.value}}
<input #ref>
```

Accommodating this required refactoring the type-checking code generator to
be able to produce Type Check Block (TCB) code non-linearly. Now, each
template is processed and a list of TCB operations (`TcbOp`s) are created.
Non-linearity is modeled via dependencies between operations, with the
appropriate protection in place for circular dependencies.

These changes rework the compiler not to output the raw selectors in the projectionDef, but to parse the selector in ngProjectAs and to store it on the TAttributes.
