This reverts commit 00f3c58bb9.
Rolling back because it could be breaking e2e tests that assert that
there are no errors in the console after the assertions have run. We can
re-add this in v10.
PR Close#35845
Changes the Ivy unknown element/property messages from being logged with `console.warn` to `console.error`. This should make them a bit more visible without breaking existing apps. Furthermore, a lot of folks filter out warning messages in the dev tools' console, whereas errors are usually still shown.
Fixes#35699.

It's an error to declare a variable twice on a specific template:
```html

This commit introduces a template type-checking error which helps to detect
and diagnose this problem.

This is a follow up to #35637 which resolved a similar issue for `ComponentFactoryResolver`, but not the root cause. When a `NgModuleRef` is created, it instantiates an `Injector` internally which in turn resolves all of injector types. This can result in a circular call that results in an error, because the module is one of the injector types being resolved.
These changes work around the issue by allowing the constructor to run before resolving the injector types.

This patch is a follow-up patch to 35c9f0dc2f.
It changes the `computeStyle` function to handle situations where
non string based values are returned from `window.getComputedStyle`.
This situation usually ocurrs in Node-based test environments where
the element or `window.getComputedStyle` is mocked out.

Switches our tslint setup to the standard `tslint.json` linter excludes.
The set of files that need to be linted is specified through a Yarn script.
For IDEs, open files are linted with the closest tslint configuration, if the
tslint IDE extension is set up, and the source file is not excluded.
We cannot use the language service plugin for tslint as we have multiple nested
tsconfig files, and we don't want to add the plugin to each tsconfig. We
could reduce that bloat by just extending from a top-level tsconfig that
defines the language service plugin, but unfortunately the tslint plugin does
not allow the use of tslint configs which are not part of the tsconfig project.
This is problematic since the tslint configuration is at the project root, and we
don't want to copy tslint configurations next to each tsconfig file.
Additionally, linting of `d.ts` files has been re-enabled. This has been
disabled in the past and a TODO has been left. This commit fixes the
lint issues and re-enables linting.

`ɵɵgetInheritedFactory()` is called from generated code for a component which extends another class. This function is detected by Closure to have a side effect and is not able to tree shake the component as a result. Marking it with `noSideEffects()` tells Closure it can remove this function under the relevant tree shaking conditions.
PR Close#35769
`ɵɵNgOnChangesFeature()` would set `ngInherit`, which is a side effect and also not necessary. This was pulled out to module scope so the function itself can be pure. Since it only curries another function, the call is entirely unnecessary. Updated the compiler to only generate a reference to this function, rather than a call to it, and removed the extra curry indirection.
PR Close#35769
This marks the function are "pure" and eligible to be tree shaken by Closure. Without this, initializing `ngDevMode` is considered a side effect which prevents this function from being tree shaken and also any component which calls it.
PR Close#35769
This is useful for propagating return values without them being converted to a string. It still provides the same guarantees to Closure, which will assume that the function invoked is pure and can be tree-shaken accordingly.

This commit performs a modularization of the Language Service's existing
diagnostic messages. Such a modularization has two primary advantages:
- Centralization and decoupling of error messages from the code that
generates them makes it easy to add/delete/edit diagnostic messages,
and allows for independent iteration of diagnostic messages and
diagnostic generation.
- Prepares for additional features like annotating the locations where a
diagnostic is generated and enabling the configuration of which
diagnostics should be reported by the language service.
Although it would be preferable to place the diagnostics registry in an
independent JSON file, for ease of typing diagnostic types as an enum
variant of 'ts.DiagnosticCategory', the registry is stored as an object.

Before this change `[class]` and `[className]` were both converted into `ɵɵclassMap`. The implication of this is that at runtime we could not differentiate between the two and as a result we treated `@Input('class')` and `@Input('className)` as equivalent.
This change makes `[class]` and `[className]` distinct. The implication of this is that `[class]` becomes `ɵɵclassMap` instruction but `[className]` becomes `ɵɵproperty' instruction. This means that `[className]` will no longer participate in styling and will overwrite the DOM `class` value.

The `ng_package` rule currently creates incorrect UMD module exports
if an entry-point has a module name with numbers included.
For example, consider an entry-point called `@angular/cdk/a11y`. The UMD
module name should be `ng.cdk.a11y`. Instead, `ng_package` currently generates
an UMD module export called `ng.cdk.a11Y`.
This is because the logic for converting dash-case to camel case is
invalid as it uses Starlark's `title()` method. The title method
converts text to title case while we actually just want to capitalize
the first letter of a dash-case segment.
Fixes angular/components#18652.

Adds a new entry-point to the `@angular/bazel` `ng_package` test that
contains numbers in the name. e.g. `example/a11y`. This test is added

is incorrectly generated. i.e. `example.a11Y` is generated instead of
`example.a11y`.

This commit extends the range of tNode types that may have local refs to include `TNodeType.Container` to account for `<ng-template>`s. Original changes in https://github.com/angular/angular/pull/33415 didn't include that type and as a result, an error is thrown at runtime in case an i18n block contains an `<ng-template>` with local refs.

When the `NgIf` directive is used in a template, its context variables
can be used to capture the bound value. This is typically used together
with a pipe or function call, where the resulting value is captured in a
context variable. There's two syntax forms available:
1. Binding to `NgIfContext.ngIf` using the `as` syntax:
```html
<span *ngIf="(user$ | async) as user">{{user.name}}</span>
```
2. Binding to `NgIfContext.$implicit` using the `let` syntax:
```html
<span *ngIf="user$ | async; let user">{{user.name}}</span>
```
Because of the semantics of `ngIf`, it is known that the captured
context variable is non-nullable, however the template type checker
would not consider them as such and still report errors when
`strictNullTypes` is enabled.
This commit updates `NgIf`'s context guard to make the types of the
context variables non-nullable, avoiding the issue.

This commit removes the `NullAstVisitor` and `visitAstChildren` exported
from `packages/compiler/src/expression_parser/ast.ts` because they
contain duplicate and buggy implementation, and their use cases could be
sufficiently covered by `RecursiveAstVisitor` if the latter implements the
`visit` method. This use case is only needed in the language service.
With this change, any visitor that extends `RecursiveAstVisitor` could
just define their own `visit` function and the parent class will behave
correctly.
A bit of historical context:
In language service, we need a way to tranverse the expression AST in a
selective manner based on where the user's cursor is. This means we need a
"filtering" function to decide which node to visit and which node to not
visit. Instead of refactoring `RecursiveAstVisitor` to support this,
`visitAstChildren` was created. `visitAstChildren` duplicates the
implementation of `RecursiveAstVisitor`, but introduced some bugs along
the way. For example, in `visitKeyedWrite`, it visits
```
obj -> key -> obj
```
instead of
```
obj -> key -> value
```
Moreover, because of the following line
```
visitor.visit && visitor.visit(ast, context) || ast.visit(visitor, context);
```
`visitAstChildren` visits every node *twice*.

The `packages/localize/src/tools` folder was excluded
from the top level `tsconfig.json` which meant that in IDEs
these source files were not being given the correct configuration.
It was originally excluded because it required the native `node` typings
but this is no longer a requirement.
Removing this folder from the exclusion list exposed a new issue
where there was a typings mismatch between `@babel/...` sources
and the associated `@types/babel__...` typings packages.
A clean up of the package.json and yarn.lock appears to fix this.

For view and content queries, the Ivy compiler attempts to statically
evaluate the predicate token so that string predicates containing
comma-separated reference names can be split into an array of strings
during compilation. When the predicate is a dynamic value that cannot be
statically interpreted at compile time, the compiler would previously
produce an error. This behavior breaks a use-case where an `InjectionToken`
is being used as query predicate, as the usage of the `new` keyword
prevents such predicates from being statically evaluated.
This commit changes the behavior to no longer produce an error for
dynamic values. Instead, the expression is emitted as is into the
generated code, postponing the evaluation to happen at runtime.

Source-maps in the wild could be badly formatted,
causing the source-map flattening processing to fail
unexpectedly. Rather than causing the whole of ngcc

generated source-map instead.
PR Close#35718
Previously when rendering flattened source-maps, it was assumed that no
mapping would come from a line that is outside the lines of the actual
source content. It turns out this is not a valid assumption.
Now the code that renders flattened source-maps will handle such
mappings, with the additional benefit that the rendered source-map
will only contain mapping lines up to the last mapping, rather than a
mapping line for every content line.
