Error: error NG4004: Angular compiler option "extendedDiagnostics.checks['invalidBananaInBox']" has an unknown diagnostic category: "test".
Allowed diagnostic categories are:
warning
error
suppress
```
The assertion comes from `ExtendedTemplateCheckerImpl`, which expects a well-formed configuration, yet the compiler would construct it even when errors were found. This commit skips constructing and running extended diagnostics if the configuration had errors, which should avoid triggering these assertion errors.
I'm unfortunately not able to actually test this change. The test passes even before the fix because the `ngc` binary and end-to-end tests [don't request diagnostics unless the configuration is considered valid](https://github.com/angular/angular/blob/ed21f5c75378e1ce717ee3d76d28c8c994209de1/packages/compiler-cli/src/perform_compile.ts#L292-L293).

`Renderer2` APIs expect to be called with the namespace name rather than
the namespace URI. Rather than passing around the URI and having to
account for different calling contexts, this change consistently uses
the namespace short names.
Importantly, the URI was only used in `component_ref.ts` `create`
(because `getNamespace returned the URIs`) and `createElementNode` in
`node_manipulation.ts` (because `getNamespaceUri` also used the URIs).
In contrast, attributes would use the _short names instead of URIs_
(see `setUpAttributes` in `attrs_utils.ts`). These names are pulled
directly from the attribute, i.e. `xhtml:href` and not converted to URI.
This dichotomy is confusing and unnecessary. The change here aligns the two
approaches in order to provide consistently throughout the system.
This relates to #44766 because the `createElementNode` was calling the
`AnimationRenderer.createElement` which delegates to the
`ServerRenderer`, which in turn was only set up to expect short names.
As a result, the `NAMESPACE_URIS` lookup failed and `Domino` created
the `svg` as a regular `Element` which does not have a `styles`
property.

Mock dates in EventsComponent tests are parsed in inconsistent ways
across platforms/browsers, which makes the comparison to the mocked
UTC "now" date behave differently causing the test to fail. This fix
ensures that the mocked "now" date is parsed in the same way as the
test dates to avoid inconsistencies.

Extended diagnostics provide additional analysis about Angular templates by emitting warnings for specific patterns known to be error prone or cause developer confusion. Currently, there are two such diagnostics which are enabled by default:
* `invalidBananaInBox` emits a warning if a user writes a two-way binding backwards like `([foo])="bar"`, when they actually wanted `[(foo)]="bar"`.
* `nullishCoalescingNotNullable` emits a warning if a binding attempts to perform nullish coalescing (`??`) on a type which does not include `null` or `undefined`, such as `{{ foo ?? 'bar' }}` where `foo` is defined as `string` instead of `string | null`.
These diagnostics are enabled as warnings by default, but this can be configured in the `tsconfig.json` like so:
```jsonc
{
"angularCompilerOptions": {
"extendedDiagnostics": {
// The categories to use for specific diagnostics.
"checks": {
// Maps check name to its category.
"invalidBananaInBox": "suppress"
},
// The category to use for any diagnostics not listed in `checks` above.
"defaultCategory": "error"
}
}
}
```
Allowed categories for a diagnostic are `warning` (default), `error`, or `suppress`. `warning` emits the diagnostic but allows the compilation to succeed, `error` *will* fail the compilation, while `suppress` will ignore the diagnostic altogether.
The initial release has two diagnostics, and we are hoping to expand this longer term to add more diagnostics and provide additional insight into Angular templates to detect and surface developer mistakes *before* hours of debugging are wasted.

Submitting it separately will greatly simplify the risk of landing Typed Forms. This change should have no visible impact on normal users of FormControl.

The directive matching pass that happens during template compilation is
redundant, since directive matching has already happened during the resolution
phase of ngtsc and only matching declarables are provided to the template
compiler. In JIT mode the declarables only become available after the primary
template compilation has completed, so there is no need to perform directive
matching in both JIT and AOT mode.

This commit reduces the analysis work that needs to happen during an
incremental rebuild by properly recording files for which no traits were found
in the set of files that have no traits, such that the same file doesn't have
to be reanalyzed during subsequent rebuilds. It also excludes shim files from
analysis.

Bundlers like Rollup may use an element access expression for an export
declaration, which causes ngcc to ignore those export declarations possibly
resulting in incomplete processing of packages.
Element access syntax may be used when the declared name is not considered
as valid JS identifier, but bundlers may be conservative in determining whether
an identifier can be used (to emit a property access) and opt for a string
literal in an element access instead.
The element access syntax introduces a problem for ngcc, where it wouldn't
consider such export as class declaration, causing them to be skipped. The
ngtsc compiler is implemented with the assumption that all class declarations
use a `ts.Identifier` as name, whereas the element access is using a string
literal for the declared name. This makes it troublesome for ngcc to support
this syntax form in UMD bundles.
To work around the problem, this function transforms these access expressions
into regular property accesses. The source text is parsed to an AST to allow
finding the element accesses in a robust way, after which the affected text
ranges are replaced with property accesses in the original source text.

The jasmine used in the docs is
```typescript
expect(<variableName>).<matcher>(predicate, failOutput)
```
The new version should be
```typescript
expect(<variableName>).withContext(failOutput).<matcher>(predicate)
```
So, this commit mainly focuses on changing the former to latter with
format below
```typescript
expect(<variableName>)
.withContext(failOutput)
.<matcher>(predicate)
```

This is a major improvement over the current situation, in which no constructor signature is documented whatsoever.

In the `Element` node of a parsed `<svg>` element, the `name` is recorded
as `:svg:svg`. When the Angular Indexer ran over this element, it would
attempt to find this name in the template text and fail, as the namespace
portion of the name was added automatically at parse time and is of course
missing from the original template.
This commit changes the indexer to detect these namespaced elements and only
search for the tag name.

When parsing a binding with a comment at the end of the expression, the
parser previously had logic to offset the parsed spans by the length of the
comment. This logic seemed not to serve any useful purpose, and instead
resulted in the corruption of the spans. For example, in the expression
`{{foo // comment}}`, the parser would map the parsed `foo` `PropertyRead`
node at the location of the characters 'ent' from the comment suffix.
This commit removes that logic, correcting the parsed spans of such nodes in
the presence of comments. Removing this logic does not seem to have caused
any tests to fail.

Previously, the Angular Indexer made an assumption that in any binding to
a property of an `ImplicitReceiver`, the property name begins at the start
of the binding. This is true for normal reads from `ImplicitReceiver` as
the implicit receiver has no representation in the template.
However, `ThisReceiver` inherits from `ImplicitReceiver` and _does_ have a
template representation. Such a binding looks like `{{this.foo}}`. This
commit corrects the logic of the indexer to use the `nameSpan` of the
property binding instead of its `sourceSpan` to locate the identifier.
