Keen Yee Liau c8584e5d36 refactor(language-service): Replace TypeDiagnostic with ng.Diagnostic (#35085)
This commit cleans up `expression_type.ts` by

1. Removing the unnecessary `TypeDiagnostic` class. It's replaced by
`ng.Diagnostic`.
2. Consolidating `reportError()` and `reportWarning()` to
`reportDiagnostic()`.

This is prep work so that we could make some of the type diagnostics a
suggestion in later PRs.

Misko Hevery 01308e4c7c refactor(ivy): Remove `TNode.directives` in favor of `TData` (#35050)
`TNode.directives` was introduced in https://github.com/angular/angular/pull/34938. Turns out that it is unnecessary because the information is already present it `TData` when combining with `TNode.directiveStart` and `TNode.directiveEnd`

Mainly this is true (conceptually):
```
expect(tNode.directives).toEqual(
    tData.slice(
        tNode.directivesStart,
        tNode.directivesEnd - tNode.DirectivesStart -1
    )
);
```

The refactoring removes `TNode.directives` and adds `TNode.directiveStyling` as we still need to keep location in the directive in `TNode`

Pete Bacon Darwin 3d4067a464 fix(ngcc): do not lock if the target is not compiled by Angular (#35057)
To support parallel CLI builds we instruct developers to pre-process
their node_modules via ngcc at the command line.

Despite doing this ngcc was still trying to set a lock when it was being
triggered by the CLI for packages that are not going to be processed,
since they are not compiled by Angular for instance.

This commit checks whether a target package needs to be compiled
at all before attempting to set the lock.

Pete Bacon Darwin 2bfddcf29f feat(ngcc): automatically clean outdated ngcc artifacts (#35079)
If ngcc gets updated to a new version then the artifacts
left in packages that were processed by the previous
version are possibly invalid.

Previously we just errored if we found packages that
had already been processed by an outdated version.

Now we automatically clean the packages that have
outdated artifacts so that they can be reprocessed
correctly with the current ngcc version.

cexbrayat fcfce99e9e fix(common): remove extra & in http params (#34896)
Previous to this commit, HTTP params like `{ a: '1', b: [], c: '3' }` resulted in a request like `a=1&&c=3` (note the double &&).

The ideal fix would probably be to stringify these params to `a=1&b=&c=3` like we do for empty string values. But that might be breaking as some APIs may rely on the absence of the parameter.

This fixes the issue in a compatible way by just removing the extra and unnecessary `&`, resulting in `a=1&c=3`.

Misko Hevery ee8b8f52aa feat(ivy): Change static priority resolution to be same level as directive it belongs to (#34938)
This change changes the priority order of static styling.

Current priority:
```
(least priority)
- Static
  - Component
  - Directives
  - Template
- Dynamic Binding
  - Component
    - Map/Interpolation
    - Property
  - Directives
    - Map/Interpolation
    - Property
  - Template
    - Map/Interpolation
    - Property
(highest priority)
```

The issue with the above priority is this use case:

```
<div style="color: red;" directive-which-sets-color-blue>
```
In the above case the directive will win and the resulting color will be `blue`. However a small change of adding interpolation to the example like so. (Style interpolation is coming in https://github.com/angular/angular/pull/34202)
```
<div style="color: red; width: {{exp}}px" directive-which-sets-color-blue>
```
Changes the priority from static binding to interpolated binding which means now the resulting color is `red`. It is very surprising that adding an unrelated interpolation and style can change the `color` which was not changed. To fix that we need to make sure that the static values are associated with priority of the source (directive or template) where they were declared. The new resulting priority is:

```
(least priority)
- Component
  - Static
  - Map/Interpolation
  - Property
- Directives
  - Static
  - Map/Interpolation
  - Property
- Template
  - Static
  - Map/Interpolation
  - Property

Ayaz Hafiz b608fa55f0 fix(language-service): warn, not error, on missing context members (#35036)
The language service reports an error when a directive's template
context is missing a member that is being used in a template (e.g. if
`$implicit` is being used with a template context typed as `any`).
While this diagnostic message is valuable, typing template contexts
loosely as `any` or `object` is very widespread in community packages,
and often still compiles correctly, so reporting the diagnostic as an
error may be misleading to users.

This commit changes the diagnostic to be a warning, and adds additional
information about how the user can eliminate the warning entirely -- by
refining the template context type.

ayazhafiz b64ead5cb8 fix(language-service): prune duplicate returned definitions (#34995)
Sometimes, a request for definitions will return multiple of the same
definition. This can happen in at least the cases of

- two-way bindings (one of the same definition for the property and
  event binding)
- multiple template binding expressions in the same attribute
  - something like "*ngFor="let i of items; trackBy: test" has two
    template bindings, resulting in two template binding ASTs at the
    same location (the attribute span). The language service then parses
    both of these bindings individually, resulting in two independent
    but identical definitions. For more context, see https://github.com/angular/angular/pull/34847#discussion_r371006680.

This commit prunes duplicate definitions by signing definitions with
their location, and checking if that location signature has been seen in
a previous definition returned to the client.

George Kalpakas 669df70da5 fix(ivy): ensure `DebugNode`/`DebugElement` are tree-shakeable in Ivy (#35003)
There are different `DebugNode`/`DebugElement` implementations (and
associated helper functions) for ViewEngine and Ivy. Additionally, these
classes/functions, which are defined inside the `core` package, are
imported by the `platform-browser` package.

Previously, this code was not tree-shaken as expected in Ivy. #30130
partially addressed the issue, but only for the case where `core` and
`platform-browser` end up in the same closure after webpack's scope
hoisting. In cases where this is not the case, our webpack/terser based
tooling is not capable of tree-shaking it.

This commit fixes the problem, by ensuring that the code retained in Ivy
mode (due to the cross-package import) does not unnecessarily reference
`DebugNode`/`DebugElement`, allowing the code to be tree-shaken away.
This results in a 7.6KB reduction in the size of the main angular.io
bundle.

Keen Yee Liau 3414ef276e refactor(language-service): Avoid leaking host outside of LanguageService (#34941)
As part of the effort to tighten the API surface of
`TypeScriptServiceHost` in preparation for the migration to Ivy, I realized
some recently added APIs are not strictly needed.
They can be safely removed without sacrificing functionality.

This allows us to clean up the code, especially in the implementation of
QuickInfo, where the `TypeScriptServiceHost` is leaked outside of the
`LanguageService` class.

This refactoring also cleans up some duplicate code where the QuickInfo
object is generated. The logic is now consolidated into a simple
`createQuickInfo` method shared across two different implementations.

Miško Hevery 9bd9590767 refactor(ivy): change styling to use programmatic API on updates (#34804)
Previously we would write to class/style as strings `element.className` and `element.style.cssText`. Turns out that approach is good for initial render but not good for updates. Updates using this approach are problematic because we have to check to see if there was an out of bound write to style and than perform reconciliation. This also requires the browser to bring up CSS parser which is expensive.

Another problem with old approach is that we had to queue the DOM writes and flush them twice. Once on element advance instruction and once in `hostBindings`. The double flushing is expensive but it also means that a directive can observe that styles are not yet written (they are written after directive executes.)

The new approach uses `element.classList.add/remove` and `element.style.setProperty/removeProperty` API for updates only (it continues to use `element.className` and `element.style.cssText` for initial render as it is cheaper.) The other change is that the styling changes are applied immediately (no queueing). This means that it is the instruction which computes priority. In some circumstances it may result in intermediate writes which are than overwritten with new value. (This should be rare)

Overall this change deletes most of the previous code and replaces it with new simplified implement. The simplification results in code savings.

Miško Hevery 5aabe93abe refactor(ivy): Switch styling to new reconcile algorithm (#34616)
NOTE: This change must be reverted with previous deletes so that it code remains in build-able state.

This change deletes old styling code and replaces it with a simplified styling algorithm.

The mental model for the new algorithm is:
- Create a linked list of styling bindings in the order of priority. All styling bindings ere executed in compiled order and than a linked list of bindings is created in priority order.
- Flush the style bindings at the end of `advance()` instruction. This implies that there are two flush events. One at the end of template `advance` instruction in the template. Second one at the end of `hostBindings` `advance` instruction when processing host bindings (if any).
- Each binding instructions effectively updates the string to represent the string at that location. Because most of the bindings are additive, this is a cheap strategy in most cases. In rare cases the strategy requires removing tokens from the styling up to this point. (We expect that to be rare case)S Because, the bindings are presorted in the order of priority, it is safe to resume the processing of the concatenated string from the last change binding.

NOTE: This change deletes code and creates a BROKEN SHA. If reverting this SHA needs to be reverted with the next SHA to get back into a valid state.

The change removes the fact that `NgStyle`/`NgClass` is special and colaborates with the `[style]`/`[class]` to merge its styles. By reverting to old behavior we have better backwards compatiblity since it is no longer treated special and simply overwrites the styles (same as VE)

Miško Hevery 2961bf06c6 refactor(ivy): move `hostVars`/`hostAttrs` from instruction to `DirectiveDef` (#34683)
This change moves information from instructions to declarative position:
- `ɵɵallocHostVars(vars)` => `DirectiveDef.hostVars`
- `ɵɵelementHostAttrs(attrs)` => `DirectiveDef.hostAttrs`

When merging directives it is necessary to know about `hostVars` and `hostAttrs`. Before this change the information was stored in the `hostBindings` function. This was problematic, because in order to get to the information the `hostBindings` would have to be executed. In order for `hostBindings` to be executed the directives would have to be instantiated. This means that the directive instantiation would happen before we had knowledge about the `hostAttrs` and as a result the directive could observe in the constructor that not all of the `hostAttrs` have been applied. This further complicates the runtime as we have to apply `hostAttrs` in parts over many invocations.

`ɵɵallocHostVars` was unnecessarily complicated because it would have to update the `LView` (and Blueprint) while existing directives are already executing. By moving it out of `hostBindings` function we can access it statically and we can create correct `LView` (and Blueprint) in a single pass.

This change only changes how the instructions are generated, but does not change the runtime much. (We cheat by emulating the old behavior by calling `ɵɵallocHostVars` and `ɵɵelementHostAttrs`) Subsequent change will refactor the runtime to take advantage of the static information.

Misko Hevery 76698d38f7 refactor(ivy): Add style reconciliation algorithm (#34004)
This change introduces class/style reconciliation algorithm for DOM elements.
NOTE: The code is not yet hooked up, it will be used by future style algorithm.

Background:
Styling algorithm currently has [two paths](https://hackmd.io/@5zDGNGArSxiHhgvxRGrg-g/rycZk3N5S)
when computing how the style should be rendered.
1. A direct path which concatenates styling and uses `elemnent.className`/`element.style.cssText` and
2. A merge path which uses internal data structures and uses `element.classList.add/remove`/`element.style[property]`.

The situation is confusing and hard to follow/maintain. So a future PR will remove the merge-path and do everything with
direct-path. This however breaks when some other code adds class or style to the element without Angular's knowledge.
If this happens instead of switching from direct-path to merge-path algorithm, this change provides a different mental model
whereby we always do `direct-path` but the code which writes to the DOM detects the situation and reconciles the out of bound write.

The reconciliation process is as follows:
1. Detect that no one has modified `className`/`cssText` and if so just write directly (fast path).
2. If out of bounds write did occur, switch from writing using `className`/`cssText` to `element.classList.add/remove`/`element.style[property]`.
   This does require that the write function computes the difference between the previous Angular expected state and current Angular state.
   (This requires a parser. The advantage of having a parser is that we can support `style="width: {{exp}}px" kind of bindings.`)
   Compute the diff and apply it in non destructive way using `element.classList.add/remove`/`element.style[property]`

Properties of approach:
- If no out of bounds style modification:
  - Very fast code path: Just concatenate string in right order and write them to DOM.
  - Class list order is preserved
- If out of bounds style modification detected:
  - Penalty for parsing
  - Switch to non destructive modification: `element.classList.add/remove`/`element.style[property]`
  - Switch to alphabetical way of setting classes.

Alex Rickabaugh 24b2f1da2b refactor(ivy): introduce the 'core' package and split apart NgtscProgram (#34887)
Previously, NgtscProgram lived in the main @angular/compiler-cli package
alongside the legacy View Engine compiler. As a result, the main package
depended on all of the ngtsc internal packages, and a significant portion of
ngtsc logic lived in NgtscProgram.

This commit refactors NgtscProgram and moves the main logic of compilation
into a new 'core' package. The new package defines a new API which enables
implementers of TypeScript compilers (compilers built using the TS API) to
support Angular transpilation as well. It involves a new NgCompiler type
which takes a ts.Program and performs Angular analysis and transformations,
as well as an NgCompilerHost which wraps an input ts.CompilerHost and adds
any extra Angular files.

Together, these two classes are used to implement a new NgtscProgram which
adapts the legacy api.Program interface used by the View Engine compiler
onto operations on the new types. The new NgtscProgram implementation is
significantly smaller and easier to reason about.

The new NgCompilerHost replaces the previous GeneratedShimsHostWrapper which
lived in the 'shims' package.

A new 'resource' package is added to support the HostResourceLoader which
previously lived in the outer compiler package.

As a result of the refactoring, the dependencies of the outer
@angular/compiler-cli package on ngtsc internal packages are significantly
trimmed.

This refactoring was driven by the desire to build a plugin interface to the
compiler so that tsc_wrapped (another consumer of the TS compiler APIs) can
perform Angular transpilation on user request.

JoostK 7659f2e24b fix(ngcc): do not attempt compilation when analysis fails (#34889)
In #34288, ngtsc was refactored to separate the result of the analysis
and resolve phase for more granular incremental rebuilds. In this model,
any errors in one phase transition the trait into an error state, which
prevents it from being ran through subsequent phases. The ngcc compiler
on the other hand did not adopt this strict error model, which would
cause incomplete metadata—due to errors in earlier phases—to be offered
for compilation that could result in a hard crash.

This commit updates ngcc to take advantage of ngtsc's `TraitCompiler`,
that internally manages all Ivy classes that are part of the
compilation. This effectively replaces ngcc's own `AnalyzedFile` and
`AnalyzedClass` types, together with all of the logic to drive the
`DecoratorHandler`s. All of this is now handled in the `TraitCompiler`,
benefiting from its explicit state transitions of `Trait`s so that the
ngcc crash is a thing of the past.

George Kalpakas 5b42084912 fix(ngcc): do not collect private declarations from external packages (#34811)
Previously, while trying to build an `NgccReflectionHost`'s
`privateDtsDeclarationMap`, `computePrivateDtsDeclarationMap()` would
try to collect exported declarations from all source files of the
program (i.e. without checking whether they were within the target
package, as happens for declarations in `.d.ts` files).

Most of the time, that would not be a problem, because external packages
would be represented as `.d.ts` files in the program. But when an
external package had no typings, the JS files would be used instead. As
a result, the `ReflectionHost` would try to (unnecessarilly) parse the
file in order to extract exported declarations, which in turn would be
harmless in most cases.

There are certain cases, though, where the `ReflectionHost` would throw
an error, because it cannot parse the external package's JS file. This
could happen, for example, in `UmdReflectionHost`, which expects the
file to contain exactly one statement. See #34544 for more details on a
real-world failure.

This commit fixes the issue by ensuring that
`computePrivateDtsDeclarationMap()` will only collect exported
declarations from files within the target package.

Alex Rickabaugh 5b2fa3cfd3 fix(ivy): correctly emit component when it's removed from its module (#34912)
This commit fixes a bug in the incremental rebuild engine of ngtsc, where if
a component was removed from its NgModule, it would not be properly
re-emitted.

The bug stemmed from the fact that whether to emit a file was a decision
based purely on the updated dependency graph, which captures the dependency
structure of the rebuild program. This graph has no edge from the component
to its former module (as it was removed, of course), so the compiler
erroneously decides not to emit the component.

The bug here is that the compiler does know, from the previous dependency
graph, that the component file has logically changed, since its previous
dependency (the module file) has changed. This information was not carried
forward into the set of files which need to be emitted, because it was
assumed that the updated dependency graph was a more accurate source of that
information.

With this commit, the set of files which need emit is pre-populated with the
set of logically changed files, to cover edge cases like this.

Alex Rickabaugh cb11380515 fix(ivy): disable use of aliasing in template type-checking (#34649)
FileToModuleHost aliasing supports compilation within environments that have
two properties:

1. A `FileToModuleHost` exists which defines canonical module names for any
   given TS file.
2. Dependency restrictions exist which prevent the import of arbitrary files
   even if such files are within the .d.ts transitive closure of a
   compilation ("strictdeps").

In such an environment, generated imports can only go through import paths
which are already present in the user program. The aliasing system supports
the generation and consumption of such imports at runtime.

`FileToModuleHost` aliasing does not emit re-exports in .d.ts files. This
means that it's safe to rely on alias re-exports in generated .js code (they
are guaranteed to exist at runtime) but not in template type-checking code
(since TS will not be able to follow such imports). Therefore, non-aliased
imports should be used in template type-checking code.

This commit adds a `NoAliasing` flag to `ImportFlags` and sets it when
generating imports in template type-checking code. The testing environment
is also patched to support resolution of FileToModuleHost canonical paths
within the template type-checking program, enabling testing of this change.

Previously, when generating template type-checking code, casts to 'any' were
produced as `expr as any`, regardless of the expression. However, for
certain expression types, this led to precedence issues with the cast. For
example, `a !== b` is a `ts.BinaryExpression`, and wrapping it directly in
the cast yields `a !== b as any`, which is semantically equivalent to
`a !== (b as any)`. This is obviously not what is intended.

wrapping is permitted. For other expressions, parentheses are added to

Alex Rickabaugh 22c957a93d fix(ivy): type-checking of properties which map to multiple fields (#34649)
It's possible to declare multiple inputs for a directive/component which all
map to the same property name. This is usually done in error, as only one of
any bindings to the property will "win".

In the template type-checker, an error was previously being raised as a
result of this ambiguity. Specifically, a type constructor was produced
which required a binding for each field, but only one of the fields had
a value via the binding. TypeScript would (rightfully) error on missing
values for the remaining fields. This ultimately was happening when the
code which generated the default values for "unset" inputs belonging to
directives or pipes used the final mapping from properties to fields as
a source for field names.

Instead, this commit uses the original list of fields to generate unset
input values, which correctly provides values for fields which shared a
property name but didn't receive the final binding.

Paul Gschwendtner 6b468f9b2e fix(ngcc): libraries using spread in object literals cannot be processed (#34661)
Consider a library that uses a shared constant for host bindings. e.g.

```ts
export const BASE_BINDINGS= {
  '[class.mat-themed]': '_isThemed',
}

----

@Directive({
  host: {...BASE_BINDINGS, '(click)': '...'}

})
export class Dir2 {}
```

Previously when these components were shipped as part of the
library to NPM, consumers were able to consume `Dir1` and `Dir2`.
No errors showed up.

Now with Ivy, when ngcc tries to process the library, an error
will be thrown. The error is stating that the host bindings should
be an object (which they obviously are). This happens because
TypeScript transforms the object spread to individual
`Object.assign` calls (for compatibility).

The partial evaluator used by the `@Directive` annotation handler
is unable to process this expression because there is no
integrated support for `Object.assign`. In View Engine, this was
not a problem because the `metadata.json` files from the library
were used to compute the host bindings.

George Kalpakas 93ffc67bfb fix(ngcc): update `package.json` deterministically (#34870)
Ngcc adds properties to the `package.json` files of the entry-points it
processes to mark them as processed for a format and point to the
created Ivy entry-points (in case of `--create-ivy-entry-points`). When
running ngcc in parallel mode (which is the default for the standalone
ngcc command), multiple formats can be processed simultaneously for the
same entry-point and the order of completion is not deterministic.

Previously, ngcc would append new properties at the end of the target
object in `package.json` as soon as the format processing was completed.
As a result, the order of properties in the resulting `package.json`
(when processing multiple formats for an entry-point in parallel) was
not deterministic. For tools that use file hashes for caching purposes
(such as Bazel), this lead to a high probability of cache misses.

This commit fixes the problem by ensuring that the position of
properties added to `package.json` files is deterministic and
independent of the order in which each format is processed.

Keen Yee Liau f723a27a71 refactor(language-service): Consistent naming between ts and ng LanguageService (#34888)
This commit makes the Angular Language Service interface a strict subset
of TypeScript's Language Service by renaming all methods to be
consistent with TypeScript's.

The custom Angular `LanguageService` interface was needed before the
inception of TypeScript tsserver plugin, but is now obsolete since
Angular LS is a proper tsserver plugin.

This allows us to easily adapt to upstream TS changes in the future, and
also allows us to reuse all data types defined in TypeScript.

The issue is only in Ivy, because that the only place where we pass in the `isHostElement` flag.

Pete Bacon Darwin e0ad9ecda0 fix(ivy): ensure that `LOCALE_ID` is set after app initializers (#34830)
Before ivy it was possible to configure a mutable service value
in an application initializer (by providing an `APP_INITIALIZER`)
that could be read in the provider of `LOCALE_ID`. This is a common
scenario if you wanted to load the locale id asynchronously from
an HTTP request for instance.

When using the ivy, the runtime needs to be told what the current
locale is, which is done by calling the `setLocaleId()` function with
the value injected by the `LOCALE_ID` token. Previously this was
being done before the application initializers were run, which meant
that the `LOCALE_ID` provider was being executed before the
app initializers had a chance to get a new value for it.

Now this initalization of the locale for the ivy runtime is done after the
application initializers have been run.

Igor Minar 63c9c2d2be fix: work around 'noImplicityAny' incompatibility due to ts3.7 update (#34798)
Typescript 3.7 now emits d.ts files for getters differently than prior versions,
and there seems to be a bug in how it strips private types without replacing them
with explicit 'any' type. This then leads to compilation failures in projects compiled
against our packages that don't have skipLibCheck turned on but do have strict or
noImplicitAny check on.

I'm working around this by marking the affected getters as @internal and
adding a test to prevent future regressions.

Pete Bacon Darwin 85b5c365fc fix(ngcc): do not add DTS deep imports to missing packages list (#34695)
When searching the typings program for a package for imports a
distinction is drawn between missing entry-points and deep imports.

Previously in the `DtsDependencyHost` these deep imports may be
marked as missing if there was no typings file at the deep import path.
Instead there may be a javascript file instead. In practice this means
the import is "deep" and not "missing".

Now the `DtsDependencyHost` will also consider `.js` files when checking
for deep-imports, and it will also look inside `@types/...` for a suitable
deep-imported typings file.

George Kalpakas cfbb1a1e77 fix(ngcc): correctly detect dependencies in CommonJS (#34528)
Previously, `CommonJsDependencyHost.collectDependencies()` would only
find dependencies via imports of the form `var foo = require('...');` or
`var foo = require('...'), bar = require('...');` However, CommonJS
files can have imports in many different forms. By failing to recognize
other forms of imports, the associated dependencies were missed, which
in turn resulted in entry-points being compiled out-of-order and failing
due to that.

While we cannot easily capture all different types of imports, this
commit enhances `CommonJsDependencyHost` to recognize the following
common forms of imports:

- Imports in property assignments. E.g.:
  `exports.foo = require('...');` or
  `module.exports = {foo: require('...')};`

- Imports for side-effects only. E.g.:
  `require('...');`

- Star re-exports (with both emitted and imported heleprs). E.g.:
  `__export(require('...'));` or

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.

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.

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.

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`.

In particular, it seems to split some strings into multiple text nodes, which would've otherwise been a single node.

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 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.

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

template:

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.

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.

constructor (one with parameters types which aren't injectable). Typically
this happens in JIT mode where understanding of parameters cannot be done in
the same "up-front" way that the AOT compiler can.

This commit changes the JIT compiler to generate a new `invalidFactoryDep`
call for each invalid parameter. This instruction will error at runtime if
called, indicating both the index of the invalid parameter as well as (via
the stack trace) the factory function which was generated for the type being
constructed.

Andrew Scott a1d0f1e5d2 fix(ivy): align TestBed.overrideProvider with what happens with providers in TestBed providers array (#33769)
In Ivy, if you do:
`TestBed.configureTestingModule({providers: [{provide: Service}]});`
the injector will attempt to inject Service as if it was simply listed
in the providers array like `{providers: [Service]}`

`useValue` or `useFactory`.

Alex Rickabaugh 718d7fe5fe fix(ivy): properly parenthesize ternary expressions when emitted (#34221)
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.

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.

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.

ayazhafiz 1425e63029 fix(language-service): determine correct type for ngFor exported values (#34089)
Currently, variables of an unknown type in an `*ngFor` expression are
refined to have the type of the iterable binding of the `*ngFor`
expression. Unfortunately, this is a bug for variables aliasing
[values exported by
`*ngFor`](https://angular.io/api/common/NgForOf#local-variables),
including `index` and `first`, because they are also given the type of
the binding expression, but they are not of the binding type. For
example, in

```typescript
@Component({
  selector: 'test',
  template: `
    <div *ngFor="let hero of heroes; let i = index; let isFirst = first">
      {{ hero }}
    </div>
  `
})
export class TestComponent {
  heroes: Hero[];
}
```

The local variables `i` and `isFirst` are determined to have a type of
`Hero`, when actually their types are `number` and `boolean`,
respectively.

This commit fixes this bug by checking if the value of a variable in an
`*ngFor` expression is known to be an export and assigning the variable
the type of that export value. Only if the variable does not alias an
export is it typed with the binding value of the `*ngFor` expression.

Prior to this commit, the unknown element can happen twice for AOT-compiled components: once during compilation and once again at runtime. Due to the fact that `schemas` information is not present on Component and NgModule defs after AOT compilation, the second check (at runtime) may fail, even though the same check was successful at compile time.

Pete Bacon Darwin ee7857300b fix(ivy): i18n - ensure that escaped chars are handled in localized strings (#34065)
When creating synthesized tagged template literals, one must provide both
the "cooked" text and the "raw" (unparsed) text. Previously there were no
good APIs for creating the AST nodes with raw text for such literals.
Recently the APIs were improved to support this, and they do an extra
check to ensure that the raw text parses to be equal to the cooked text.

It turns out there is a bug in this check -
see https://github.com/microsoft/TypeScript/issues/35374.

This commit works around the bug by synthesizing a "head" node and morphing
it by changing its `kind` into the required node type.

This bring is changes to the @nodejs repository required for https://github.com/angular/angular/pull/33927. See release notes for more details: https://github.com/bazelbuild/rules_nodejs/releases/tag/0.41.0.

rules_nodejs is approaching 1.0 and breaking changes for that release are being made more frequently. In this release, the ts_devserver API changed and it no longer injects html script tags into a provided index.html file. The diff on this commit is large as this breaking change affects quite a few tests.

Also note that we don’t update @angular/bazel schematics and integration/bazel as 0.41.0 is not a recommended update for angular users yet due to the breaking changes in ts_devserver & web_package (now named pkg_web). When a suitable plain npm package that is in progress is finished then it will be possible to easily replace the html injection functionality removed from ts_devserver & pkg_web.

ayazhafiz 49804fe017 fix(language-service): determine index types accessed using dot notation (#33884)
Commit 53fc2ed8bf added support for
determining index types accessed using index signatures, but did not
include support for index types accessed using dot notation:

```typescript
const obj<T>: { [key: string]: T };
obj['stringKey']. // gets `T.` completions
obj.stringKey.    // did not peviously get `T.` completions
```

This adds support for determining an index type accessed via dot
notation by rigging an object's symbol table to return the string index
signature type a property access refers to, if that property does not
explicitly exist on the object. This is very similar to @ivanwonder's
work in #29811.

`SymbolWrapper` now takes an additional parameter to explicitly set the
type of the symbol wrapped. This is done because
`SymbolTableWrapper#get` only has access to the symbol of the index
type, _not_ the index signature symbol itself. An attempt to get the
type of the index type will give an error.

Kara Erickson 1a0ee18d62 fix(ivy): run pre-order hooks in injection order (#34026)
This commit fixes a compatibility bug where pre-order lifecycle
hooks (onInit, doCheck, OnChanges) for directives on the same
host node were executed based on the order the directives were
matched, rather than the order the directives were instantiated
(i.e. injection order).

This discrepancy can cause issues with forms, where it is common
to inject NgControl and try to extract its control property in
ngOnInit. As the NgControl directive is injected, it should be
instantiated before the control value accessor directive (and
thus its hooks should run first). This ensures that the NgControl
ngOnInit can set up the form control before the ngOnInit
for the control value accessor tries to access it.

Alex Rickabaugh 4cf197998a fix(ivy): track changes across failed builds (#33971)
Previously, our incremental build system kept track of the changes between
the current compilation and the previous one, and used its knowledge of
inter-file dependencies to evaluate the impact of each change and emit the
right set of output files.

However, a problem arose if the compiler was not able to extract a
dependency graph successfully. This typically happens if the input program
contains errors. In this case the Angular analysis part of compilation is
never executed.

If a file changed in one of these failed builds, in the next build it
appears unchanged. This means that the compiler "forgets" to emit it!

To fix this problem, the compiler needs to know the set of changes made
_since the last successful build_, not simply since the last invocation.

This commit changes the incremental state system to much more explicitly
pass information from the previous to the next compilation, and in the
process to keep track of changes across multiple failed builds, until the
program can be analyzed successfully and the results of those changes
incorporated into the emit plan.

Andrew Kushnir fc2f6b8456 fix(ivy): wrap functions from "providers" in parentheses in Closure mode (#33609)
Due to the fact that Tsickle runs between analyze and transform phases in Angular, Tsickle may transform nodes (add comments with type annotations for Closure) that we captured during the analyze phase. As a result, some patterns where a function is returned from another function may trigger automatic semicolon insertion, which breaks the code (makes functions return `undefined` instead of a function). In order to avoid the problem, this commit updates the code to wrap all functions in some expression ("privders" and "viewProviders") in parentheses.

JoostK b07b6f1d40 fix(ivy): avoid infinite recursion when evaluation source files (#33772)
When ngtsc comes across a source file during partial evaluation, it
would determine all exported symbols from that module and evaluate their
values greedily. This greedy evaluation strategy introduces unnecessary
work and can fall into infinite recursion when the evaluation result of
an exported expression would circularly depend on the source file. This
would primarily occur in CommonJS code, where the `exports` variable can
be used to refer to an exported variable. This variable would be
resolved to the source file itself, thereby greedily evaluating all
exported symbols and thus ending up evaluating the `exports` variable
again. This variable would be resolved to the source file itself,
thereby greedily evaluating all exported symbols and thus ending u
evaluating the `exports` variable again. This variable would be
resolved to the source file itself, thereby greedily evaluating all
exported symbols and thus ending up evaluating the `exports` variable
again. This variable would be resolved to the source file itself,
thereby greedily evaluating all exported symbols and thus ending up
evaluating the `exports` variable again. This went on for some time
until all stack frames were exhausted.

This commit introduces a `ResolvedModule` that delays the evaluation of
its exports until they are actually requested. This avoids the circular
dependency when evaluating `exports`, thereby fixing the issue.

Alex Rickabaugh 08a4f10ee7 fix(ivy): move setClassMetadata calls into a pure iife (#33337)
This commit transforms the setClassMetadata calls generated by ngtsc from:

```typescript
/*@__PURE__*/ setClassMetadata(...);
```

to:

```typescript
/*@__PURE__*/ (function() {
  setClassMetadata(...);
})();
```

Without the IIFE, terser won't remove these function calls because the
function calls have arguments that themselves are function calls or other
impure expressions. In order to make the whole block be DCE-ed by terser,
we wrap it into IIFE and mark the IIFE as pure.

It should be noted that this change doesn't have any impact on CLI* with
build-optimizer, which removes the whole setClassMetadata block within
the webpack loader, so terser or webpack itself don't get to see it at
all. This is done to prevent cross-chunk retention issues caused by
webpack's internal module registry.

* actually we do expect a short-term size regression while
https://github.com/angular/angular-cli/pull/16228
is merged and released in the next rc of the CLI. But long term this
change does nothing to CLI + build-optimizer configuration and is done
primarly to correct the seemingly correct but non-function PURE annotation
that builds not using build-optimizer could rely on.

Alex Rickabaugh b54ed980ed fix(ivy): retain JIT metadata unless JIT mode is explicitly disabled (#33671)
NgModules in Ivy have a definition which contains various different bits
of metadata about the module. In particular, this metadata falls into two
categories:

* metadata required to use the module at runtime (for bootstrapping, etc)
in AOT-only applications.
* metadata required to depend on the module from a JIT-compiled app.

The latter metadata consists of the module's declarations, imports, and
exports. To support JIT usage, this metadata must be included in the
generated code, especially if that code is shipped to NPM. However, because
this metadata preserves the entire NgModule graph (references to all
directives and components in the app), it needs to be removed during
optimization for AOT-only builds.

Previously, this was done with a clever design:

1. The extra metadata was added by a function called `setNgModuleScope`.
A call to this function was generated after each NgModule.
2. This function call was marked as "pure" with a comment and used
`noSideEffects` internally, which causes optimizers to remove it.

The effect was that in dev mode or test mode (which use JIT), no optimizer
runs and the full NgModule metadata was available at runtime. But in
production (presumably AOT) builds, the optimizer runs and removes the JIT-
specific metadata.

However, there are cases where apps that want to use JIT in production, and
still make an optimized build. In this case, the JIT-specific metadata would
be erroneously removed. This commit solves that problem by adding an
`ngJitMode` global variable which guards all `setNgModuleScope` calls. An
optimizer can be configured to statically define this global to be `false`
for AOT-only builds, causing the extra metadata to be stripped.

A configuration for Terser used by the CLI is provided in `tooling.ts` which
sets `ngJitMode` to `false` when building AOT apps.

Alex Rickabaugh eb6975acaf fix(ivy): don't infer template context types when in full mode (#33537)
The Ivy template type-checker is capable of inferring the type of a
structural directive (such as NgForOf<T>). Previously, this was done with
fullTemplateTypeCheck: true, even if strictTemplates was false. View Engine
previously did not do this inference, and so this causes breakages if the
type of the template context is not what the user expected.

In particular, consider the template:

```html
<div *ngFor="let user of users as all">
  {{user.index}} out of {{all.length}}
</div>
```

As long as `users` is an array, this seems reasonable, because it appears
that `all` is an alias for the `users` array. However, this is misleading.

In reality, `NgForOf` is rendered with a template context that contains
both a `$implicit` value (for the loop variable `user`) as well as a
`ngForOf` value, which is the actual value assigned to `all`. The type of
`NgForOf`'s template context is `NgForContext<T>`, which declares `ngForOf`'s
type to be `NgIterable<T>`, which does not have a `length` property (due to
its incorporation of the `Iterable` type).

This commit stops the template type-checker from inferring template context
types unless strictTemplates is set (and strictInputTypes is not disabled).

Alex Rickabaugh 4be8929844 fix(ivy): always re-analyze the program during incremental rebuilds (#33862)
Previously, the ngtsc compiler attempted to reuse analysis work from the
previous program during an incremental build. To do this, it had to prove
that the work was safe to reuse - that no changes made to the new program
would invalidate the previous analysis.

The implementation of this had a significant design flaw: if the previous
program had errors, the previous analysis would be missing significant
information, and the dependency graph extracted from it would not be
sufficient to determine which files should be re-analyzed to fill in the
gaps. This often meant that the build output after an error was resolved
would be wholly incorrect.

This commit switches ngtsc to take a simpler approach to incremental
rebuilds. Instead of attempting to reuse prior analysis work, the entire
program is re-analyzed with each compilation. This is actually not as
expensive as one might imagine - analysis is a fairly small part of overall
compilation time.

Based on the dependency graph extracted during this analysis, the compiler
then can make accurate decisions on whether to emit specific files. A new
suite of tests is added to validate behavior in the presence of source code
level errors.

This new approach is dramatically simpler than the previous algorithm, and
should always produce correct results for a semantically correct program.s

Alex Rickabaugh bb290cefae fix(core): make QueryList implement Iterable in the type system (#33536)
Originally, QueryList implemented Iterable and provided a Symbol.iterator
on its prototype. This caused issues with tree-shaking, so QueryList was
refactored and the Symbol.iterator added in its constructor instead. As
part of this change, QueryList no longer implemented Iterable directly.

Unfortunately, this meant that QueryList was no longer assignable to
Iterable or, consequently, NgIterable. NgIterable is used for NgFor's input,
so this meant that QueryList was not usable (in a type sense) for NgFor
iteration. View Engine's template type checking would not catch this, but
Ivy's did.

As a fix, this commit adds the declaration (but not the implementation) of
the Symbol.iterator function back to QueryList. This has no runtime effect,
so it doesn't affect tree-shaking of QueryList, but it ensures that
QueryList is assignable to NgIterable and thus usable with NgFor.

Alex Rickabaugh 850aee2448 fix(ivy): emit fs-relative paths when rootDir(s) aren't in effect (#33828)
Previously, the compiler assumed that all TS files logically within a
project existed under one or more "root directories". If the TS compiler
option `rootDir` or `rootDirs` was set, they would dictate the root
directories in use, otherwise the current directory was used.

Unfortunately this assumption was unfounded - it's common for projects
without explicit `rootDirs` to import from files outside the current
working directory. In such cases the `LogicalProjectStrategy` would attempt
to generate imports into those files, and fail. This would lead to no
`ReferenceEmitStrategy` being able to generate an import, and end in a
compiler assertion failure.

This commit introduces a new strategy to use when there are no `rootDirs`
explicitly present, the `RelativePathStrategy`. It uses simpler, filesystem-
relative paths to generate imports, even to files above the current working
directory.

JoostK e666d283dd fix(ngcc): correctly associate decorators with aliased classes (#33878)
In flat bundle formats, multiple classes that have the same name can be
suffixed to become unique. In ES5-like bundles this results in the outer
declaration from having a different name from the "implementation"

As an example, the following code would fail to have a `Directive`
decorator as ngcc would search for `__decorate` calls that refer to
`AliasedDirective$1` by name, whereas the `__decorate` call actually
uses the `AliasedDirective` name.

ayazhafiz 53fc2ed8bf feat(language-service): completions support for indexed types (#33775)
Previously, indexing a container type would not return completions for
the indexed type because for every TypeScript type, the recorded index
type was always marked as `undefined`, regardless of the index
signature.

This PR now returns the index type of TypeScript containers with numeric
or string index signatures. This allows use to generate completions for
arrays and defined index types:

```typescript
interface Container<T> {
  [key: string]: T;
}
const ctr: Container<T>;
ctr['stringKey']. // gives `T.` completions

const arr: T[];
arr[0]. // gives `T.` completions
```

Note that this does _not_ provide completions for properties indexed by
string literals, e.g.

```typescript
interface Container<T> {
  foo: T;
}
const ctr: Container<T>;
ctr['foo']. // does not give `T.` completions
```

Keen Yee Liau c5a75fd807 fix(language-service): Recompute analyzed modules only when source files change (#33806)
This commit fixes a bug brought up by @andrius-pra whereby the language
service host would recompute the analyzed modules even when none of the
source files changes. This is due to a bug in our unit test that
precludes non-TS files from incrementing the project version.
Consequently, when the external template is updated, the program remains
the same.

With the bug fixed, the next step is to figure out if any source files
have been added / changed / removed since the last computation. The
previously analyzed could be safely retained only when none of these
operations happen.

George Kalpakas 033aba9351 fix(ngcc): do not emit ES2015 code in ES5 files (#33514)
Previously, ngcc's `Renderer` would add some constants in the processed
files which were emitted as ES2015 code (e.g. `const` declarations).
This would result in invalid ES5 generated code that would break when

This commit fixes it by adding a `printStatement()` method to
`RenderingFormatter`, which can convert statements to JavaScript code in
a suitable format for the corresponding `RenderingFormatter`.
Additionally, the `translateExpression()` and `translateStatement()`
ngtsc helper methods are augmented to accept an extra hint to know
whether the code needs to be translated to ES5 format or not.

George Kalpakas 704775168d fix(ngcc): generate correct metadata for classes with getter/setter properties (#33514)
While processing class metadata, ngtsc generates a `setClassMetadata()`
call which (among other things) contains info about property decorators.
Previously, processing getter/setter pairs with some of ngcc's
`ReflectionHost`s resulted in multiple metadata entries for the same
property, which resulted in duplicate object keys, which in turn causes
an error in ES5 strict mode.

This commit fixes it by ensuring that there are no duplicate property
names in the `setClassMetadata()` calls.

In addition, `generateSetClassMetadataCall()` is updated to treat
`ClassMember#decorators: []` the same as `ClassMember.decorators: null`
(i.e. omitting the `ClassMember` from the generated `setClassMetadata()`
call). Alternatively, ngcc's `ReflectionHost`s could be updated to do
this transformation (`decorators: []` --> `decorators: null`) when
reflecting on class members, but this would require changes in many
places and be less future-proof.

For example, given a class such as:

```ts
class Foo {
  @Input() get bar() { return 'bar'; }
  set bar(value: any) {}
}
```

...previously the generated `setClassMetadata()` call would look like:

```ts
ɵsetClassMetadata(..., {
  bar: [{type: Input}],
  bar: [],
});
```

The same class will now result in a call like:

```ts
ɵsetClassMetadata(..., {
  bar: [{type: Input}],
});
```

crisbeto fcdada53f1 fix(ivy): constant object literals shared across element and component instances (#33705)
Currently if a consumer does something like the following, the object literal will be shared across the two elements and any instances of the component template. The same applies to array literals:

```
<div [someDirective]="{}"></div>
<div [someDirective]="{}"></div>
```

These changes make it so that we generate a pure function even if an object is constant so that each instance gets its own object.

Note that the original design for this fix included moving the pure function factories into the `consts` array. In the process of doing so I realized that pure function are also used inside of directive host bindings which means that we don't have access to the `consts`.

These changes also:
* Fix an issue that meant that the `pureFunction0` instruction could only be run during creation mode.
* Make the `getConstant` utility slightly more convenient to use. This isn't strictly required for these changes to work, but I had made it as a part of a larger refactor that I ended up reverting.

JoostK 15f8638b1c fix(ivy): ensure module scope is rebuild on dependent change (#33522)
During incremental compilations, ngtsc needs to know which metadata
from a previous compilation can be reused, versus which metadata has to
be recomputed as some dependency was updated. Changes to
directives/components should cause the NgModule in which they are
declared to be recompiled, as the NgModule's compilation is dependent
on its directives/components.

When a dependent source file of a directive/component is updated,
however, a more subtle dependency should also cause to NgModule's source
file to be invalidated. During the reconciliation of state from a
previous compilation into the new program, the component's source file
is invalidated because one of its dependency has changed, ergo the
NgModule needs to be invalidated as well. Up until now, this implicit
dependency was not imposed on the NgModule. Additionally, any change to
a dependent file may influence the module scope to change, so all
components within the module must be invalidated as well.

This commit fixes the bug by introducing additional file dependencies,
as to ensure a proper rebuild of the module scope and its components.

The `ngInjectableDef` property was renamed to `ɵprov`, but core must
still support both because there are published libraries that use the

We are only interested in such properties that are defined directly on

the defintion is specifically for the given type.

Previously if you tried to inject a class that had `ngInjectableDef` but
also inherited `ɵprov` then the check would fail on the `ɵprov` property
and never even try the `ngInjectableDef` property resulting in a failed
injection.

the DI so they just inject the `DOCUMENT` token and are done.

Ivy is special because it does not rely upon the DI and must
get hold of the document some other way. There are a limited
number of places relevant to ivy that currently consume a global
document object.

The solution is modelled on the `LOCALE_ID` approach, which has
`getLocaleId()` and `setLocaleId()` top-level functions for ivy (see
`core/src/render3/i18n.ts`).  In the rest of Angular (i.e. using DI) the
`LOCALE_ID` token has a provider that also calls setLocaleId() to
ensure that ivy has the same value.

This commit defines `getDocument()` and `setDocument() `top-level
functions for ivy. Wherever ivy needs the global `document`, it calls
`getDocument()` instead.  Each of the platforms (e.g. Browser, Server,
WebWorker) have providers for `DOCUMENT`. In each of those providers
they also call `setDocument()` accordingly.

It looks like there was a typo when it originally was
written. As it works right now, the `beforeEach` and
`afterEach` cancel each other out. But then
`ensureDocument()` is called anyway in the `withBody()`
function.

With this change there is no need to call `ensureDocument() in the
`withBody() function.

Pete Bacon Darwin b3c3000004 fix(ngcc): ensure that adjacent statements go after helper calls (#33689)
Previously the renderers were fixed so that they inserted extra
"adjacent" statements after the last static property of classes.

In order to help the build-optimizer (in Angular CLI) to be able to
tree-shake classes effectively, these statements should also appear
after any helper calls, such as `__decorate()`.

This commit moves the computation of this positioning into the
`NgccReflectionHost` via the `getEndOfClass()` method, which
returns the last statement that is related to the class.

Andrew Kushnir eece138fa7 fix(ivy): provider override via TestBed should remove old providers from the list (#33706)
While overriding providers in Ivy TestBed (via TestBed.overrideProvider call), the old providers were retained in the list, since the override takes precedence. However, presence of providers in the list might have side-effect: if a provider has the `ngOnDestroy` lifecycle hook, this hook will be registered and invoked later (when component is destroyed). This commit updates TestBed logic to clear provider list by removing the ones which have overrides.

Prior to this patch all the styling benchmarks only tested for
template map-based style/class bindings. Because of each of the bindings

When the Angular compiler is operated through the ngc binary in watch
mode, changing a template in an external file would not cause the
component to be recompiled if Ivy is enabled.

There was a problem with how a cached compiler host was present that was
unaware of the changed resources, therefore failing to trigger a
recompilation of a component whenever its template changes. This commit
fixes the issue by ensuring that information about modified resources is
correctly available to the cached compiler host.

Miško Hevery c25503b142 test(ivy): Have more descriptive names for `LView` (#33449)
When debugging `LView`s it is easy to get lost since all of them have
the same name. This change does three things:

1. It makes `TView` have an explicit type:
  - `Host`: for the top level `TView` for bootstrap
  - `Component`: for the `TView` which represents components template
  - `Embedded`: for the `TView` which represents an embedded template
2. It changes the name of `LView` to `LHostView`, `LComponentView`, and
  `LEmbeddedView` depending on the `TView` type.
3. For `LComponentView` and `LEmbeddedView` we also append the name of
  of the `context` constructor. The result is that we have `LView`s which
  are name as: `LComponentView_MyComponent` and `LEmbeddedView_NgIfContext`.

The above changes will make it easier to understand the structure of the
application when debugging.

NOTE: All of these are behind `ngDevMode` and will get removed in
production application.

Greg Magolan 1c22e464b2 build: remove deps on legacy nodejs rules rollup_bundle internals (#33201) (#33607)
The legacy nodejs rules rollup_bundle is now deprecated and will be removed in the nodejs rules 1.0 release due in mid-November. This PR brings in the rules_nodejs internal API deps that ng_rollup_bundle, ng_package and ls_rollup_bundle depend on into this repo to break the dependency. In the future these rules should switch to use the new rollup_bundle via a macro as done in https://github.com/angular/angular/pull/33329 but this is not possible right now due to the complication of having esm5 re-rooted ts_library dependencies.

The es6 sources now have .mjs extensions so they no longer need to be re-rooted to `{package}.es6`. This eliminates the need for the collect_es6_sources() function.

Note: repo has been updated to the newest working version of rollup which is 1.25.2. There is some regression in 1.26.0 which causes the following bundling failure:
