Previously, resource paths beginning with '/' (aka "rooted" paths, which
are not actually absolute filesystem paths, but are relative to the
TypeScript project root directory) were not handled correctly. The leading
'/' was stripped and the path was resolved as if it was relative, but with
no containing file for context. This led to resources in different rootDirs
not being found.
Instead, such rooted paths are now resolved without TypeScript's help, by
checking each root directory. A test is added to this effect.

When determining if a `main` path points to a UMD or CommonJS
format, the contents of the file need to be loaded and parsed.
Previously, it was assumed that the path referred to the exact filename,
but did not account for normal module resolution semantics, where the
path may be missing an extension or refer to a directory containing an
`index.js` file.

Since `goog.getMsg` does not process ICUs (post-processing is required via goog.i18n.MessageFormat, https://google.github.io/closure-library/api/goog.i18n.MessageFormat.html) and placeholder format used for ICUs and regular messages inside `goog.getMsg` are different, the current implementation (that assumed the same placeholder format) needs to be updated. This commit updates placeholder format used inside ICUs from `{$placeholder}` to `{PLACEHOLDER}` to better align with Closure. ICU placeholders (that were left as is prior to this commit) are now replaced with actual values in post-processing step (inside `i18nPostprocess`).

`i18nStart` was calling `allocExpando` even if there was 0 new variable created.
This created a new expando instruction with the value 0 which was later interpreted as the start of a new expando block instead of just skipping 0 instructions.

Fixes Ivy's return value for `DebugNode.context` not being consistent for the case where there is both a structural directive and a component on a node. In `ViewEngine` the instance of the component would be returned, whereas in Ivy the context of the directive is returned.
Also adds a couple of extra test cases for how `DebugNode.context` deals with directives.

Paths can be mapped directly to files, which was not being taken

Now if a `pathMapping` pattern does not exist or is a file, then we try

Previously, ngcc had to walk the entire `node_modules` tree looking for
entry-points, even if it only needed to process a single target entry-point
and its dependencies.
This added up to a few seconds to each execution of ngcc, which is noticeable
when being run via the CLI integration.
Now, if an entry-point target is provided, only that target and its entry-points
are considered rather than the whole folder tree.
PR Close#30525
When profiling ngcc it is notable that a large amount of time
is spent dealing with an exception that is thrown (and handled
internally by fs) when checking the existence of a file.
We check file existence a lot in both finding entry-points
and when TS is compiling code. This commit adds a simple
cached `FileSystem`, which wraps a real `FileSystem` delegate.
This will reduce the number of calls through to `fs.exists()` and
`fs.readFile()` on the delegate.
Initial benchmarks indicate that the cache is miss to hit ratio
for `exists()` is about 2:1, which means that we save about 1/3
of the calls to `fs.existsSync()`.
Note that this implements a "non-expiring" cache, so it is not suitable
for a long lived `FileSystem`, where files may be modified externally.
The cache will be updated if a file is changed or moved via
calls to `FileSystem` methods but it will not be aware of changes
to the files system from outside the `FileSystem` service.
For ngcc we must create a new `FileSystem` service
for each run of `mainNgcc` and ensure that all file operations
(including TS compilation) use the `FileSystem` service.
This ensures that it is very unlikely that a file will change
externally during `mainNgcc` processing.

The ngcc tool adds namespaced imports to files when compiling. The ngtsc
tooling was not processing types correctly when they were imported via
such namespaces. For example:
```
export declare class SomeModule {
static withOptions(...): ModuleWithProviders<ɵngcc1.BaseModule>;
```
In this case the `BaseModule` was being incorrectly attributed to coming
from the current module rather than the imported module, represented by
`ɵngcc1`.

If a package delcares a class internally on an NgModule, ngcc
needs to be able to add a public export to this class's type.
Previously, if the typing file for the declared is not imported
from the typings entry-point file, then ngcc cannot find it.
Now we try to guess the .d.ts files from the equivalent .js
files.

Adds a schematic and tslint rule that automatically migrate the consumer from `Renderer` to `Renderer2`. Supports:
* Renaming imports.
* Renaming property and method argument types.
* Casting to `Renderer`.
* Mapping all of the methods from the `Renderer` to `Renderer2`.
Note that some of the `Renderer` methods don't map cleanly between renderers. In these cases the migration adds a helper function at the bottom of the file which ensures that we generate valid code with the same return value as before. E.g. here's what the migration for `createText` looks like.
Before:
```
class SomeComponent {
createAndAddText() {
const node = this._renderer.createText(this._element.nativeElement, 'hello');
node.textContent += ' world';
}
}
```
After:
```
class SomeComponent {
createAndAddText() {
const node = __rendererCreateTextHelper(this._renderer, this._element.nativeElement, 'hello');
node.textContent += ' world';
}
}
function __rendererCreateTextHelper(renderer: any, parent: any, value: any) {
const node = renderer.createText(value);
if (parent) {
renderer.appendChild(parent, node);
}
return node;
}

Updates the decision made in #31341; this is for the Angular indexer
inside Google. The indexer currently passes (and ngc-wrapped#compile
accepts) a bazel host to use, but because many methods are overwritten
specially for Angular compilation a better approach is to pass an old
bazel compiler host and siphon methods needed off of it before creating
a new host. This enables that.

Adds the new `classMapInterpolate1` through `classMapInterpolate8` instructions which handle interpolations inside the `class` attribute and moves the interpolation logic internally. This allows us to remove the `interpolationX` instructions in a follow-up PR.
These changes also add an error if an interpolation is encountered inside a `style` tag (e.g. `style="width: {{value}}"`). Up until now this would actually generate valid instructions, because `styleMap` goes through the same code path as `classMap` which does support interpolation. At runtime, however, `styleMap` would set invalid styles that look like `<div style="0:w;1:i;2:d;3:t;4:h;5::;7:1;">`. In `ViewEngine` interpolations inside `style` weren't supported either, however there we'd output invalid styles like `<div style="unsafe">`, even if the content was trusted.

There's no build time dependency from @angular/core to @angular/compiler,
so core can't directly refer to compiler types. To overcome this limitation,
there's a facade layer defined in the compiler and duplicated in core,
such that during runtime all types will correctly align.
There's a testcase in the compiler that verifies that all such facade types
are compatible across core and compiler, such that the core types can't get
misaligned with the actual definitions in the compiler. This suite of
tests were missing the `R3BaseMetadataFacade` facade type, so it was possible
for this type to get out of sync.

When a class uses Angular decorators such as `@Input`, `@Output` and
friends without an Angular class decorator, they are compiled into a
static `ngBaseDef` field on the class, with the TypeScript declaration
of the class being altered to declare the `ngBaseDef` field to be of type
`ɵɵBaseDef`. This type however requires a generic type parameter that
corresponds with the type of the class, however the compiler did not
provide this type parameter. As a result, compiling a program where such
invalid `ngBaseDef` declarations are present will result in compilation
errors.
This commit fixes the problem by providing the generic type parameter.
