Greg Magolan 7203169c3d build: update integration/bazel & @angular/bazel schematics to rules_nodejs 1.0.0 (#34589)
For the purposes of the integration test the zone.js script & bundle script tags can just go into the source index.html itself. The purpose of the integration test is is to test @angular/bazel & ng_module & ng_package so there is no need to exercise html_insert_assets in integration/bazel.

Greg Magolan 9bb349e1c8 refactor: handle breaking changes in rules_nodejs 1.0.0 (#34589)
The major one that affects the angular repo is the removal of the bootstrap attribute in nodejs_binary, nodejs_test and jasmine_node_test in favor of using templated_args --node_options=--require=/path/to/script. The side-effect of this is that the bootstrap script does not get the require.resolve patches with explicitly loading the targets _loader.js file.

ayazhafiz 4d95c3d39a refactor(language-service): rename expression completions method (#34518)
This commit renames `addAttributeValuesToCompletions`, which generates
expression completions and is not exclusive to processing attributes, to
`processExpressionCompletions`. Also removes the expression completion
logic in `visitBoundText` for a call to `processExpressionCompletions`.

The conditional branch in `visitBoundText` is also removed. This branch
was added in one of the first commits to the language service
(519a324454) and appears to be
unnecessary, as the expression AST is constructed from the template
position anyway.

George Kalpakas c3271ac22a fix(ngcc): recognize re-exports with imported TS helpers in CommonJS and UMD (#34527)
Previously, the `CommonJsReflectionHost` and `UmdReflectionHost` would
only recognize re-exports of the form `__export(...)`. This is what
re-exports look like, when the TypeScript helpers are emitted inline
(i.e. when compiling with the default [TypeScript compiler options][1]
that include `noEmitHelpers: false` and `importHelpers: false`).

However, when compiling with `importHelpers: true` and [tslib][2] (which
is the recommended way for optimized bundles), the re-exports will look
like: `tslib_1.__exportStar(..., exports)`
These types of re-exports were previously not recognized by the
CommonJS/UMD `ReflectionHost`s and thus ignored.

This commit fixes this by ensuring both re-export formats are
recognized.

crisbeto b1eb84c57e refactor(ivy): remove calls into other instructions from pipe instructions (#33714)
A while ago we made a pass through all instructions to make sure that none of them call directly into other instructions, however it seems like missed the `pipeBind*` since they still call into the pure functions. The result is that we have some unnecessary duplicated accesses of global state like `getLView` which are called twice in a row with nothing changing.

These changes move the common functionality into a shared file and make the pipe instructions call into them with the global state instead.

ayazhafiz 794dcb58d3 fix(language-service): do not use an i18n parser for templates (#34531)
The compiler's `I18NHtmlParser` may expand template nodes that have
internationalization metadata attached to them; for instance,

```html
<div i18n="@@i18n-el">{{}}</div>
```

gets expanded to an AST with the i18n metadata extracted and text filled
in as necessary; to the language service, the template above, as read in
the AST, now looks something like

```html
<div>{{$implicit}}</div>
```

This is undesirable for the language service because we want to preserve
the original form of the source template source code, and have
information about the original values of the template. The language
service also does not need to use an i18n parser -- we don't generate
any template output.

To fix this turns out to be as easy as moving to using a raw
`HtmlParser`.

---

A note on the testing strategy: as mentioned above, we don't need to use
an i18n parser, but we don't **not** need to use one if the parser
does not heavily modify the template AST. For this reason, the tests
target the functionality of not modifying a template with i18n metadata
rather than testing that the language service does not use an i18n parser.

Pete Bacon Darwin 58cdc22791 fix(ngcc): handle UMD factories that do not use all params (#34660)
In some cases, where a module imports a dependency
but does not actually use it, UMD bundlers may remove
the dependency parameter from the UMD factory function
definition.

For example:

```
import * as x from 'x';
import * as z from 'z';
export const y = x;
```

may result in a UMD bundle including:

```
(function (global, factory) {
    typeof exports === 'object' && typeof module !== 'undefined' ?
        factory(exports, require('x'), require('z')) :
    typeof define === 'function' && define.amd ?
        define(['exports', 'x', 'z'], factory) :
    (global = global || self, factory(global.myBundle = {}, global.x));
}(this, (function (exports, x) { 'use strict';
...
})));
```

Note that while the `z` dependency is provide in the call,
the factory itself only accepts `exports` and `x` as parameters.

Previously ngcc appended new dependencies to the end of the factory
function, but this breaks in the above scenario. Now the new
dependencies are prefixed at the front of parameters/arguments
already in place.

Pete Bacon Darwin 570574df5b fix(ngcc): don't crash if symbol has no declarations (#34658)
In some cases TypeScript is unable to identify a valid

This fix ensures that ngcc does not crash if such a symbol

Follow-up from [this discussion](https://github.com/angular/angular/pull/33419#discussion_r339296216). In Ivy we don't use the schema to validate tag names, but instead we use feature detection to figure out whether an element is supported. While this should generally be more accurate, it'll also end up throwing for some more innocent cases. E.g. now Ivy throws an error for `main` elements in IE which is accurate since IE doesn't support the element, but is annoying since there is no functionality attached.

These changes switch to logging a warning instead, similarly to what we're doing for unknown properties.

George Kalpakas 07ea6cf582 fix(ngcc): avoid error due to circular dependency in `EsmDependencyHost` (#34512)
Previously, there was circular dependency between `ngcc/src/utils.ts`,
`ngcc/src/dependencies/dependency_host.ts` and
`ngcc/src/dependencies/esm_dependency_host.ts`. More specifically,
`utils.ts` would [import from `esm_dependency_host.ts`][1], which would
[import from `dependency_host.ts`][2], which would in turn
[import from `utils.ts`][3].

This might be fine in some environments/module formats, but it can cause
unclear errors in the transpiled CommonJS/UMD format (given how Node.js
handles [cycles in module resolution][4]).
(An example error can be found [here][5].)

This commit fixes the problem by moving the code that depends on
`EsmDependencyHost` out of `utils.ts` and into a dedicated file under
`dependencies/`. It also converts the `createDtsDependencyHost()`
function to a class for consistency with the rest of the
`DependencyHost`s.

Pete Bacon Darwin 4f42de9704 fix(ngcc): capture entry-point dependencies from typings as well as source (#34494)
ngcc computes a dependency graph of entry-points to ensure that
entry-points are processed in the correct order. Previously only the imports
in source files were analysed to determine the dependencies for each
entry-point.

This is not sufficient when an entry-point has a "type-only" dependency
 - for example only importing an interface from another entry-point.
In this case the "type-only" import does not appear in the
source code. It only appears in the typings files. This can cause a
dependency to be missed on the entry-point.

This commit fixes this by additionally processing the imports in the
typings program, as well as the source program.

Note that these missing dependencies could cause unexpected flakes when
running ngcc in async mode on multiple processes due to the way that
ngcc caches files when they are first read from disk.

Andrew Kushnir effb92dfae fix(ivy): skip field inheritance if InheritDefinitionFeature is present on parent def (#34244)
The main logic of the `InheritDefinitionFeature` is to go through the prototype chain of a given Component and merge all Angular-specific information onto that Component def. The problem happens in case there is a Component in a hierarchy that also contains the `InheritDefinitionFeature` (i.e. it extends some other Component), so it inherits all Angular-specific information from its super class. As a result, the root Component may end up having duplicate information inherited from different Components in hierarchy.

Let's consider the following structure: `GrandChild` extends `Child` that extends `Base` and the `Base` class has a `HostListener`. In this scenario `GrandChild` and `Child` will have `InheritDefinitionFeature` included into the `features` list. The processing will happend in the following order:

- `Child` inherits `HostListener` from the `Base` class
- `GrandChild` inherits `HostListener` from the `Child` class
- since `Child` has a parent, `GrandChild` also inherits from the `Base` class

The result is that the `GrandChild` def has duplicated host listener, which is not correct.

This commit introduces additional logic that checks whether we came across a def that has `InheritDefinitionFeature` feature (which means that this def already inherited information from its super classes). If that's the case, we skip further fields-related inheritance logic, but keep going though the prototype chain to look for super classes that contain other features (like NgOnChanges), that we need to invoke for a given Component def.

ayazhafiz ee46b9b44f fix(language-service): correctly parse expressions in an attribute (#34517)
Currently, the language service provides completions in a template node
attribute by first checking if the attribute contains template bindings
to provide completions for, and then providing completions for the
expression in the attribute.

In the latter case, the expression AST was being constructed
"synthetically" inside the language service, in particular declaring the
expression to be a `PropertyRead` with an implicit receiver.
Unfortunately, this AST can be incorrect if the expression is actually a
property read on a component property receiver (e.g. when reading
`key` in the expression `obj.key`, `obj` is the receiver).

The fix is pretty simple - rather than a synthetic construction of the
AST, ask the expression parser to parse the expression in the attribute.

JoostK 1de49ba369 refactor(ivy): consistently translate types to `ts.TypeNode` (#34021)
The compiler has a translation mechanism to convert from an Angular
`Type` to a `ts.TypeNode`, as appropriate. Prior to this change, it
would translate certain Angular expressions into their value equivalent
in TypeScript, instead of the correct type equivalent. This was possible
as the `ExpressionVisitor` interface is not strictly typed, with `any`s
being used for return values.

For example, a literal object was translated into a
`ts.ObjectLiteralExpression`, containing `ts.PropertyAssignment` nodes
as its entries. This has worked without issues as their printed
representation is identical, however it was incorrect from a semantic
point of view. Instead, a `ts.TypeLiteralNode` is created with
`ts.PropertySignature` as its members, which corresponds with the type
declaration of an object literal.

JoostK f27187c063 perf(ivy): support simple generic type constraints in local type ctors (#34021)
In Ivy's template type checker, type constructors are created for all
directive types to allow for accurate type inference to work. The type
checker has two strategies for dealing with such type constructors:

1. They can be emitted local to the type check block/type check file.
2. They can be emitted as static `ngTypeCtor` field into the directive
itself.

The first strategy is preferred, as it avoids having to update the
directive type which would cause a more expensive rebuild. However, this
strategy is not suitable for directives that have constrained generic
types, as those constraints would need to be present on the local type
constructor declaration. This is not trivial, as it requires that any
type references within a type parameter's constraint are imported into
the local context of the type check block.

For example, lets consider the `NgForOf` directive from '@angular/core'
looks as follows:

```typescript
import {NgIterable} from '@angular/core';

export class NgForOf<T, U extends NgIterable<T>> {}
```

The type constructor will then have the signature:
`(o: Pick<i1.NgForOf<T, U>, 'ngForOf'>) => i1.NgForOf<T, U>`

Notice how this refers to the type parameters `T` and `U`, so the type
constructor needs to be emitted into a scope where those types are
available, _and_ have the correct constraints.

Previously, the template type checker would detect the situation where a
type parameter is constrained, and would emit the type constructor
using strategy 2; within the directive type itself. This approach makes
any type references within the generic type constraints lexically
available:

```typescript
export class NgForOf<T, U extends NgIterable<T>> {
  static ngTypeCtor<T = any, U extends NgIterable<T> = any>
    (o: Pick<NgForOf<T, U>, 'ngForOf'>): NgForOf<T, U> { return null!; }
}
```

This commit introduces the ability to emit a type parameter with
constraints into a different context, under the condition that it can
be imported from an absolute module. This allows a generic type
constructor to be emitted into a type check block or type check file
according to strategy 1, as imports have been generated for all type
references within generic type constraints. For example:

```typescript
import * as i0 from '@angular/core';
import * as i1 from '@angular/common';

const _ctor1: <T = any, U extends i0.NgIterable<T> = any>
  (o: Pick<i1.NgForOf<T, U>, 'ngForOf'>) => i1.NgForOf<T, U> = null!;
```

Notice how the generic type constraint of `U` has resulted in an import
of `@angular/core`, and the `NgIterable` is transformed into a qualified
name during the emitting process.

ayazhafiz 19944c2424 feat(compiler): record end of expression Token (#33549)
In the past, only the starting index of an expression Token has been
recorded, so a parser could demarkate the span of a token only by the
start locations of two tokens. This may lead to trailing whitespace
being included in the token span:

```html
{{ token1   + token2 }}
   ^^^^^^^^^             recorded span of `token1`
```

It's also not enough for a parser to determine the end of a token by
adding the length of the token value to the token's start location,
because lexed expression values may not exactly reflect the source code.
For example, `"d\\"e"` is lexed as a string token whose value is `d"e`.

Instead, this commit adds a `end` field to expression tokens. `end`
is one past the last index of the token source code. This will enable a
parser to determine the span of a token just by looking at that token.

This is a breaking change because the contructor interface of `Token`
has changed.

Keen Yee Liau 2dffe65cfd fix(language-service): completions after "let x of |" in ngFor (#34473)
This commit fixes a bug in which we do testing for completions.
Subsequently, this exposes another bug in our implementation whereby
suggestions are not provided in "ngFor" where there should have been.

Currently, multiple test cases are grouped together in a single
template. This requires the template to be somewhat complete so that
test cases that depend on variables declared earlier would pass.

Consider the following example:

```
  template: `
    <div *ngFor="let ~{for-person}person of ~{for-people}people">
      <span>Name: {{~{for-interp-person}person.~{for-interp-name}name}}</span>
      <span>Age: {{person.~{for-interp-age}age}}</span>
    </div>`,
```

In order to test `~{for-interp-person}`, `people` has to be included after
`~{for-people}`. This means the test case for `~{for-people}` is not
reflective of the actual use case because the variable is already there!
In real case, the expression would be incomplete, and our implementation
failed to take that into account.

This commit breaks such test into individual tests, and fix the bugs in
the underlying implementation.

crisbeto cf37c003ff feat(ivy): error in ivy when inheriting a ctor from an undecorated base (#34460)
Angular View Engine uses global knowledge to compile the following code:

```typescript
export class Base {
  constructor(private vcr: ViewContainerRef) {}
}

@Directive({...})
export class Dir extends Base {
  // constructor inherited from base
}
```

Here, `Dir` extends `Base` and inherits its constructor. To create a `Dir`
the arguments to this inherited constructor must be obtained via dependency
injection. View Engine is able to generate a correct factory for `Dir` to do
this because via metadata it knows the arguments of `Base`'s constructor,
even if `Base` is declared in a different library.

In Ivy, DI is entirely a runtime concept. Currently `Dir` is compiled with
an ngDirectiveDef field that delegates its factory to `getInheritedFactory`.
This looks for some kind of factory function on `Base`, which comes up
empty. This case looks identical to an inheritance chain with no
constructors, which works today in Ivy.

Both of these cases will now become an error in this commit. If a decorated
class inherits from an undecorated base class, a diagnostic is produced
informing the user of the need to either explicitly declare a constructor or
to decorate the base class.

Alex Rickabaugh 498a2ffba3 fix(ivy): don't produce template diagnostics when scope is invalid (#34460)
Previously, ngtsc would perform scope analysis (which directives/pipes are
available inside a component's template) and template type-checking of that
template as separate steps. If a component's scope was somehow invalid (e.g.
its NgModule imported something which wasn't another NgModule), the
component was treated as not having a scope. This meant that during template
type-checking, errors would be produced for any invalid expressions/usage of
other components that should have been in the scope.

This commit changes ngtsc to skip template type-checking of a component if
its scope is erroneous (as opposed to not present in the first place). Thus,
users aren't overwhelmed with diagnostic errors for the template and are
only informed of the root cause of the problem: an invalid NgModule scope.

JoostK 3959511b80 fix(ivy): avoid duplicate errors in safe navigations and template guards (#34417)
The template type checker generates TypeScript expressions for any
expression that occurs in a template, so that TypeScript can check it
and produce errors. Some expressions as they occur in a template may be
translated into TypeScript code multiple times, for instance a binding
to a directive input that has a template guard.

One example would be the `NgIf` directive, which has a template guard to
narrow the type in the template as appropriate. Given the following
template:

```typescript
@Component({
  template: '<div *ngIf="person">{{ person.name }}</div>'
})
class AppComponent {
  person?: { name: string };
}
```

A type check block (TCB) with roughly the following structure is
created:

```typescript
function tcb(ctx: AppComponent) {
  const t1 = NgIf.ngTypeCtor({ ngIf: ctx.person });
  if (ctx.person) {
    "" + ctx.person.name;
  }
}
```

Notice how the `*ngIf="person"` binding is present twice: once in the
type constructor call and once in the `if` guard. As such, TypeScript
will check both instances and would produce duplicate errors, if any
were found.

Another instance is when the safe navigation operator is used, where an
expression such as `person?.name` is emitted into the TCB as
`person != null ? person!.name : undefined`. As can be seen, the
left-hand side expression `person` occurs twice in the TCB.

This commit adds the ability to insert markers into the TCB that
indicate that any errors within the expression should be ignored. This
is similar to `@ts-ignore`, however it can be applied more granularly.

Pete Bacon Darwin f22a6eb00e fix(ngcc): correctly match aliased classes between src and dts files (#34254)
The naïve matching algorithm we previously used to match declarations in
source files to declarations in typings files was based only on the name
of the thing being declared.  This did not handle cases where the declared
item had been exported via an alias - a common scenario when one of the two
file sets (source or typings) has been flattened, while the other has not.

The new algorithm tries to overcome this by creating two maps of export
name to declaration (i.e. `Map<string, ts.Declaration>`).
One for the source files and one for the typings files.
It then joins these two together by matching export names, resulting in a
new map that maps source declarations to typings declarations directly
(i.e. `Map<ts.Declaration, ts.Declaration>`).

This new map can handle the declaration names being different between the
source and typings as long as they are ultimately both exported with the
same alias name.

Further more, there is one map for "public exports", i.e. exported via the
root of the source tree (the entry-point), and another map for "private
exports", which are exported from individual files in the source tree but
not necessarily from the root. This second map can be used to "guess"
the mapping between exports in a deep (non-flat) file tree, which can be
used by ngcc to add required private exports to the entry-point.

Paul Gschwendtner 5cecd97493 feat(forms): expand NgModel disabled type to work with strict template type checking (#34438)
NgModel internally coerces any arbitrary value that will assigned
to the `disabled` `@Input` to a boolean. This has been done to
support the common case where developers set the disabled attribute
without a value. For example:

```html
<input type="checkbox" [(ngModel)]="value" disabled>
```

This worked in View Engine without any errors because inputs were
not strictly checked. In Ivy though, developers can opt-in into
strict template type checking where the attribute would be flagged.

This is because the `NgModel#isDisabled` property type-wise only
accepts a `boolean`. To ensure that the common pattern described
above can still be used, and to reflect the actual runtime behavior,
we should add an acceptance member that makes it work without type
checking errors.

Using a coercion member means that this is not a breaking change.

Currently we only run Saucelabs on PRs using the legacy View Engine
build. Switching that build to Ivy is not trivial and there are various
options:

  1. Updating the R3 switches to use POST_R3 by default. At first glance,
  this doesn't look easy because the current ngtsc switch logic seems to
  be unidirectional (only PRE_R3 to POST_R3).

  2. Updating the legacy setup to run with Ivy. This sounds like the easiest
  solution at first.. but it turns out to be way more complicated. Packages
  would need to be built with ngtsc using legacy tools (i.e. first building
  the compiler-cli; and then building packages) and View Engine only tests
  would need to be determined and filtered out. Basically it will result in
  re-auditing all test targets. This is contradictory to the fact that we have
  this information in Bazel already.

  3. Creating a new job that runs tests on Saucelabs with Bazel. We specify
  fine-grained test targets that should run. This would be a good start
  (e.g. acceptance tests) and also would mean that we do not continue maintaining
  the legacy setup..

This commit implements the third option as it allows us to move forward
with the general Bazel migration. We don't want to spend too much time
on our legacy setup since it will be removed anyway in the future.

crisbeto 0100a39e21 fix(ivy): i18n instructions thrown off by sanitizer in IE11 (#34305)
While sanitizing on browsers that don't support the `template` element (pretty much only IE), we create an inert document and we insert content into it via `document.body.innerHTML = unsafeHTML`. The problem is that IE appears to parse the HTML passed to `innerHTML` differently, depending on whether the element has been inserted into a document or not. In particular, it seems to split some strings into multiple text nodes, which would've otherwise been a single node. This ended up throwing off some of the i18n code down the line and causing a handful of failures. I've worked around it by creating a new inert `body` element into which the HTML would be inserted.

Alex Rickabaugh af95dddd7e perf(ivy): eagerly parse the template twice during analysis (#34334)
A quirk of the Angular template parser is that when parsing templates in the
"default" mode, with options specified by the user, the source mapping
information in the template AST may be inaccurate. As a result, the compiler
parses the template twice: once for "emit" and once to produce an AST with
accurate sourcemaps for diagnostic production.

Previously, only the first parse was performed during analysis. The second
parse occurred during the template type-checking phase, just in time to
produce the template type-checking file.

However, with the reuse of analysis results during incremental builds, it
makes more sense to do the diagnostic parse eagerly during analysis so that
the work isn't unnecessarily repeated in subsequent builds. This commit
refactors the `ComponentDecoratorHandler` to do both parses eagerly, which
actually cleans up some complexity around template parsing as well.

JoostK 014a7137f4 perf(compiler): use a shared interpolation regex (#34332)
The template parser has a certain interpolation config associated with
it and builds a regular expression each time it needs to extract the

JoostK 4945274080 perf(compiler): optimize cloning cursors state (#34332)
On a large compilation unit with big templates, the total time spent in
the `PlainCharacterCursor` constructor was 470ms. This commit applies
two optimizations to reduce this time:

1. Avoid the object spread operator within the constructor, as the
generated `__assign` helper in the emitted UMD bundle (ES5) does not
optimize well compared to a hardcoded object literal. This results in a
significant performance improvement. Because of the straight-forward
object literal, the VM is now much better able to optimize the memory
allocations which makes a significant difference as the
`PlainCharacterCursor` constructor is called in tight loops.

2. Reduce the number of `CharacterCursor` clones. Although cloning
itself is now much faster because of the optimization above, several
clone operations were not necessary.

Combined, these changes reduce the total time spent in the
`PlainCharacterCursor` constructor to just 10ms.

During TypeScript module resolution, a lot of filesystem requests are
done. This is quite an expensive operation, so a module resolution cache
can be used to speed up the process significantly.

This commit lets the Ivy compiler perform all module resolution with a

implementation is responsible for caching. In the case of the Angular

Alex Rickabaugh 6ba5fdc208 fix(ivy): generate a better error for template var writes (#34339)
In Ivy it's illegal for a template to write to a template variable. So the
template:

```html
<ng-template let-somevar>
  <button (click)="somevar = 3">Set var to 3</button>
</ng-template>
```

is erroneous and previously would fail to compile with an assertion error
from the `TemplateDefinitionBuilder`. This error wasn't particularly user-
friendly, though, as it lacked the context of which template or where the
error occurred.

In this commit, a new check in template type-checking is added which detects
such erroneous writes and produces a true diagnostic with the appropriate
context information.

Alex Rickabaugh 74edde0a94 perf(ivy): reuse prior analysis work during incremental builds (#34288)
Previously, the compiler performed an incremental build by analyzing and
resolving all classes in the program (even unchanged ones) and then using
the dependency graph information to determine which .js files were stale and
needed to be re-emitted. This algorithm produced "correct" rebuilds, but the
cost of re-analyzing the entire program turned out to be higher than
anticipated, especially for component-heavy compilations.

To achieve performant rebuilds, it is necessary to reuse previous analysis
results if possible. Doing this safely requires knowing when prior work is
viable and when it is stale and needs to be re-done.

The new algorithm implemented by this commit is such:

1) Each incremental build starts with knowledge of the last known good
   dependency graph and analysis results from the last successful build,
   plus of course information about the set of files changed.

2) The previous dependency graph's information is used to determine the
   set of source files which have "logically" changed. A source file is
   considered logically changed if it or any of its dependencies have
   physically changed (on disk) since the last successful compilation. Any
   logically unchanged dependencies have their dependency information copied
   over to the new dependency graph.

3) During the `TraitCompiler`'s loop to consider all source files in the
   program, if a source file is logically unchanged then its previous
   analyses are "adopted" (and their 'register' steps are run). If the file
   is logically changed, then it is re-analyzed as usual.

4) Then, incremental build proceeds as before, with the new dependency graph
   being used to determine the set of files which require re-emitting.

This analysis reuse avoids template parsing operations in many circumstances
and significantly reduces the time it takes ngtsc to rebuild a large
application.

Future work will increase performance even more, by tackling a variety of
other opportunities to reuse or avoid work.

Alex Rickabaugh 50cdc0ac1b refactor(ivy): move analysis side effects into a register phase (#34288)
Previously 'analyze' in the various `DecoratorHandler`s not only extracts
information from the decorators on the classes being analyzed, but also has
several side effects within the compiler:

* it can register metadata about the types involved in global metadata
  trackers.
* it can register information about which .ngfactory symbols are actually
  needed.

In this commit, these side-effects are moved into a new 'register' phase,
which runs after the 'analyze' step. Currently this is a no-op refactoring
as 'register' is always called directly after 'analyze'. In the future this
opens the door for re-use of prior analysis work (with only 'register' being
called, to apply the above side effects).

Also as part of this refactoring, the reification of NgModule scope
information into the incremental dependency graph is moved to the
`NgtscProgram` instead of the `TraitCompiler` (which now only manages trait
compilation and does not have other side effects).

Alex Rickabaugh 252e3e9487 refactor(ivy): formalize the compilation process for matched handlers (#34288)
Prior to this commit, the `IvyCompilation` tracked the state of each matched
`DecoratorHandler` on each class in the `ts.Program`, and how they
progressed through the compilation process. This tracking was originally
simple, but had grown more complicated as the compiler evolved. The state of
each specific "target" of compilation was determined by the nullability of
a number of fields on the object which tracked it.

This commit formalizes the process of compilation of each matched handler
into a new "trait" concept. A trait is some aspect of a class which gets
created when a `DecoratorHandler` matches the class. It represents an Ivy
aspect that needs to go through the compilation process.

Traits begin in a "pending" state and undergo transitions as various steps
of compilation take place. The `IvyCompilation` class is renamed to the
`TraitCompiler`, which manages the state of all of the traits in the active
program.

Making the trait concept explicit will support future work to incrementalize
the expensive analysis process of compilation.

JoostK 0984fbc748 fix(compiler-cli): allow declaration-only template type check members (#34296)
The metadata collector for View Engine compilations emits error symbols
for static class members that have not been initialized, which prevents
a library from building successfully when `strictMetadataEmit` is
enabled, which is recommended for libraries to avoid issues in library
consumers. This is troublesome for libraries that are adopting static
members for the Ivy template type checker: these members don't need a
value assignment as only their type is of importance, however this
causes metadata errors. As such, a library used to be required to
initialize the special static members to workaround this error,
undesirably introducing a code-size overhead in terms of emitted
JavaScript code.

the special static members for Ivy's template type checker, preventing

JoostK 22ad701134 fix(ivy): inherit static coercion members from base classes (#34296)
For Ivy's template type checker it is possible to let a directive
specify static members to allow a wider type for some input:

```typescript
export class MatSelect {

}
```

This allows a binding to the `MatSelect.disabled` input to be of type
boolean or string, whereas the `disabled` property itself is only of
type boolean.

Up until now, any static `ngAcceptInputType_*` property was not
inherited for subclasses of a directive class. This is cumbersome, as
the directive's inputs are inherited, so any acceptance member should as
well. To resolve this limitation, this commit extends the flattening of
directive metadata to include the acceptance members.

Previously, ternary expressions were emitted as:

condExpr ? trueCase : falseCase

However, this causes problems when ternary operations are nested. In
particular, a template expression of the form:

a?.b ? c : d

would have compiled to:

a == null ? null : a.b ? c : d

The ternary operator is right-associative, so that expression is interpreted
as:

a == null ? null : (a.b ? c : d)

when in reality left-associativity is desired in this particular instance:

(a == null ? null : a.b) ? c : d

This commit adds a check in the expression translator to detect such
left-associative usages of ternaries and to enforce such associativity with
parentheses when necessary.

A test is also added for the template type-checking expression translator,
to ensure it correctly produces right-associative expressions for ternaries
in the user's template.

Fixes #34087

Joey Perrott f72de51a6f build: remove compile build variable (#34280)
Remove the remaining check for compile build variable in the ng_module
rule.  Now that components is no longer relying on this build variable
we can safely remove it from our repository.

We will leave the remaining check for if the compile build variable is
used within our own repo, with plans to remove it in a couple months.
It is being kept in place to ensure that uncommitted local scripts for
our own development that we have locally, kill error as expected if
they still reference the compile build variable.

Kristiyan Kostadinov e7cf1e0580 feat(docs-infra): add the ability to expose globals (#34237)
Adds the ability to expose global symbols in the API docs via the `@globalApi` tag. Also supports optionally setting a namespace which will be added to the name automatically (e.g. `foo` will be renamed to `ng.foo`). Relevant APIs should also be exported through the `global.ts` file which will show up under `core/global`.

Keen Yee Liau 613dc1122a fix(language-service): Simplify resolution logic in banner (#34262)
Due to a bug in the existing banner, `typescript` module was require-d
instead of reusing the module passed in from tsserver.
This bug is caused by some source files in language-service that imports
`typescript` instead of `typescript/lib/tsserverlibrary`.
This is not an unsupported use case, it's just that when typescript is
resolved in the banner we have to be very careful about which modules to
"require".
The convoluted logic in the banner makes it very hard to detect
anomalies. This commit cleans it up and removes a lot of unneeded code.

This commit also removes `ts` import in typescript_host.ts and use `tss`
instead to make it less confusing.

Keen Yee Liau f05e1719cc fix(language-service): Remove getExternalFiles() (#34260)
This commit removes the `getExternalFiles()` from the tsserver plugin.
This API is no longer needed now that we do not intend to support
external templates under the plugin mode.
Instead, the external files are added to the project only when they are
opened by the user.

Martin Probst 1084d4ab49 refactor(upgrade): avoid mutable exports. (#34232)
Previously, create_angular_testing_module would export a mutable `let`
binding. The binding is already exporting using an accessor function
though, so the export on the let variable seems like an accidental
oversight.

This is functionally equivalent, but makes it easier for module
optimizers such as Closure Compiler to track down side effects and prune
modules.

Martin Probst 37bb90140c refactor(platform-browser): avoid mutable exports. (#34207)
Previously, browser_util would export a mutable `let` binding that was
initialized as a side-effect of `BrowserDetection.setup()`. This change
refactors the mutable binding into a `const` binding that is immediately
initialized in its initialized.

This is functionally equivalent, but makes it easier for module
optimizers such as Closure Compiler to track down side effects and prune
modules. It is also arguably cleaner to read (no worries about later
changes to the apparently mutable but effectively const binding).

Pete Bacon Darwin 61e8ed6623 fix(ngcc): ensure that bundle `rootDir` is the package path (#34212)
Previously the `rootDir` was set to the entry-point path but
this is incorrect if the source files are stored in a directory outside
the entry-point path. This is the case in the latest versions of the
Angular CDK.

Instead the `rootDir` should be the containing package path, which is
guaranteed to include all the source for the entry-point.

---

A symptom of this is an error when ngcc is trying to process the source of
an entry-point format after the entry-point's typings have already been
processed by a previous processing run.

During processing the `_toR3Reference()` function gets called which in turn
makes a call to `ReflectionHost.getDtsDeclaration()`. If the typings files
are also being processed this returns the node from the dts typings files.

But if we have already processed the typings files and are now processing
only an entry-point format without typings, the call to
`ReflectionHost.getDtsDeclaration()` returns `null`.

When this value is `null`, a JS `valueRef` is passed through as the DTS
`typeRef` to the `ReferenceEmitter`. In this case, the `ReferenceEmitter`
fails during `emit()` because no `ReferenceEmitStrategy` is able to provide
an emission:

1) The `LocalIdentifierStrategy` is not able help because in this case
`ImportMode` is `ForceNewImport`.
2) The `LogicalProjectStrategy` cannot find the JS file below the `rootDir`.

The second strategy failure is fixed by this PR.
