The logical filesystem would store a cached result based on the canonical path,
where the cached value contains the physical path that was originally provided.
This meant that other physical paths with an identical canonical path would use
a cached result derived from another physical path.
This inconsistency is not known to result in actual issues but is primarily
being made as a performance improvement, as using the provided physical paths
as cache key avoids the need to canonicalize the path if its result is already
cached.

The generated imports should normally use module specifiers that are valid for
use in production code, where arbitrary relative imports into e.g. node_modules
are not allowed. For template type-checking code it is however acceptable to
use relative imports, as such files are never emitted to JS code. It is
desirable to allow a filesystem relative import as fallback if an import would
otherwise fail to be generated, as doing so allows fewer situations from
needing an inline type constructor.

This commit removes the leftover `Identifiers` class that was used in the
ViewEngine compiler. The remaining usages of the `inlineInterpolate` and
`interpolate` instructions were refactored to make use of an
`InterpolationExpression` output expression to capture the argument list of an
interpolation expression. An attempt was made to refactor this further by
converting to the desired interpolation instruction immediately, but some
downstream consumers are designed in a way where the argument list itself is
needed, e.g. as other arguments need to be prepended/appended.

When `HttpTestingController.verify` is used to verify that there are not open,
unexpected requests it would throw an error with the method and URL of all pending
requests, excluding the query parameters. This is confusing, as e.g. `expectOne`
matches a URL including its query parameters and `expectOne` does include the
query parameters when it reports when no request could be matched.
This commit changes the error that is reported by `verify` to include the query
parameters.

This commit removes CSS keyframes-based code that was used to support animations in old browsers. With IE11 deprecation, all supported browsers have native WebAnimations support, so the old code can be removed. This results in ~7KB decrease of the animations package bundle size, since most of the code was non-tree-shakable.

Support for namespace URIs rather than short namespace names was added in
https://github.com/angular/angular/commit/2b9cc8503d48173492c29f5a271b61126104fbdb to
support how Ivy passed around the namespace URI rather than short name at the time.
As a side-effect, this meant that namespace URIs were supported by the
default dom renderer as part of the public API (likely unintentionally).
It did not, however extend the support to other parts of the system (setAttribute, setAttribute,
and the ServerRenderer). In the future we should decide what exactly the
semantics for dealing with namespaces should be and make it consistent.

TypeScript configures `strictNullChecks` to be disabled by default, so the nullish
coalescing check should follow the same default. The rule actively depends on
`strictNullChecks`, as TypeScript doesn't include `null`/`undefined` in its types
otherwise so the check wouldn't have a way to differentiate between them.
This commit also takes the `strict` flag into account when `strictNullChecks` itself

When the indexer encounters a location where the source span doesn't
match up with the expected identifier, the current visitor code throws
an error. Instead, this change creates an error and moves on to the next
template item. This allows the indexer to continue analysis even when
there are errors in the source mapping. In addition, it still allows callers
to surface those errors in their own way while still providing as much indexed
information as possible about a node.

An `ng-template` with an inline template (i.e. has a structural
directive) would previously not get an `undefined` `tagName` because the
logic assumed the element would be `t.Element` or `t.Content` and read
the tag name from the `name` property. For a `t.Template`, this exists
instead on the `t.tagName`. The final result would be an `tagName` of `undefined`
for the parent `t.Template`, causing failures in the indexer downstream.
This `undefined` value is actually expected in the renderer code, even
though the type does not specify this possibility. This change updates
the type of `tagName` to be `string|null` and explicitly handles the
case where there is a structural directive on an `ng-template`. You can
see how the two are differentiated in the compliance code that was
modified in this commit.

The previous fix for correcting spans with comments in
https://github.com/angular/angular/commit/59eef29a6c5d568ca80595cd7018e21ad406c85d
had the unfortunate side effect of _breaking_ the spans with comments
when there was leading whitespace. This happened because the previous
fix was testing one without a comment, identifying that the offset shouldn't
have anything added to it, and then removing that offset adjustment
(`offsets[i] + (expressionText.length - sourceToLex.length)`).
Upon further investigation, this offset adjustment _was actually
necessary_ for when the input had comments, but this was only because
the `stripComments` function used `trim` to remove whitespace for these
cases. This is the real problem -- not only does it create a ton of confusion
but also it means that the behavior of the lexer and resulting spans is
different between inputs with comments and inputs without comments.
After reviewing how the `inputLength` of `_ParseAST` was used, it
appears that the correct behavior would be to _not_ trim the input. The
`inputLength` is used to advance the current index beyond points which
have been processed. This _should_ include any whitespace. Additionally,
`inputLength` doesn't appear to be needed at all. When there was no
comment in the input, it was always equal to the `input.length` anyways.
When there _is_ a comment, it should include that comment anyways to
advance the index beyond the comment.

When running tests with code coverage using Istanbul, the code is
instrumented with coverage reporting statements. These statements are
also inserted into synthesized constructors, preventing Angular from
properly recognizing them as synthesized constructor.
This commit changes the regex to detect synthesized constructors to allow
for statements within the constructor before the `super(...arguments);`
call. This is limited to code that does not contain a `}`, but this
is sufficient to support Istanbul's coverage instrumentation statements.
The tests have been extended with an input file that is being
instrumented using `babel-plugin-istanbul` for both ES2015 and ES5
targets, in order to verify that the approach works for real-world
usages.

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.

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.
