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.

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.

This validates the `tsconfig.json` options for extended template diagnostics. It verifies:
* `strictTemplates` must be enabled if `extendedDiagnostics` have any explicit configuration.
* `extendedDiagnostics.defaultCategory` must be a valid `DiagnosticCategoryLabel`.
* `extendedDiagnostics.checks` keys must all be real diagnostics.
* `extendedDiagnostics.checks` values must all be valid `DiagnosticCategoryLabel`s.
These include new error codes, each of which prints out the exact property that was the issue and what the available options are to fix them.
It does disallow the config:
```json
{
"angularCompilerOptions": {
"strictTemplates": false,
"extendedDiagnostics": {
"defaultCategory": "suppress"
}
}
}
```
Such a configuration is technically valid and could be executed, but will be rejected by this verification logic. There isn't much reason to ever do this, since users could just drop `extendedDiagnostics` altogether and get the intended effect. This is unlikely to be a significant issue for users, so it is considered invalid for now to keep the implementation simple.
PR Close#44391
Refs #42966.
The `defaultCategory` option is used for any extended template diagnostics which do not have any specific category specified for them. It defaults to `warning`, since that is the most common behavior expected for users. This provides an easy way for users to promote all diagnostics to errors or suppress all diagnostics.
PR Close#44391
Refs #42966.
This updates `TemplateContext` to include a new `makeTemplateDiagnostic()` function which automatically uses the correct diagnostic category for that check. This makes sure that each diagnostic is emitted with the correct category. It also implicitly passes some known values like `component` and `code` to make the extended template diagnostics a little simpler. Diagnostics which are suppressed are never instantiated at all, which acts as a slight performance optimization since any emitted diagnostics would be ignored anyways.
Unfortunately, diagnostics still have access to `ctx.templateTypeChecker.makeTemplateDiagnostic()` to manually create diagnostics with a different category. Both banana in box and nullish coalescing checks include tests to make sure they respect a manually configured category. This convention should hopefully give a reasonable certainty that new diagnostics will use the correct reporting function, even if that is not strictly enforced.

This includes a mapping of extended template diagnostics to their associated diagnostic category. It is generated from the list of diagnostic names, so the list should always be implicitly kept up to date. Usage looks like:

"nullishCoalescingNotNullable": "suppress"

This moves extended template check factory invocations into the checker itself, where it can provide a more consistent API contract. Factories are called with compiler options and may return a `TemplateCheck` or `undefined` if the current options do not support that check. This allows `nullishCoalescingNotNullable` to disable itself when `strictNullChecks` is disabled without throwing errors. This gives extended template diagnostics a stronger abstraction model to define their behavior with.

The enum of extended template diagnostic names allows a global registry of first-party diagnostics with a developer-friendly string name which can be used for configuration. This name is used in the new `TemplateCheckFactory` to bind the name to a particular `ErrorCode` and make both available *before* constructing the actual template check, which is necessary to configure it appropriately.

when reordering a list with animations the list items lose their current
triggers values, that is because the reordering of an item is implemented
as follows (_note:_ the following implementation has been added in PR #23534)
- the item is removed and marked _setForRemoval_
- the item is re-inserted, and the _setForRemoval_ is changed to _setForMove_
- the player set for animating the removal is destroyed when _setForMove_ is detected
the above steps allow the element not to be animated and to keep its styling but the
triggers values get lost since the removal transition/player has already been initialized,
so this change adds a _previousTriggersValues_ map in the _REMOVAL_FLAG_ field in order to
restore the triggers values if/when the removal turns out to be a move, changing the above steps to:
- the item is removed and marked setForRemoval __and its current triggers values are saved as well__
- the item is re-inserted, and the setForRemoval is changed to setForMove
- the player set for animating the removal is destroyed when setForMove is detected __and the
trigger values are re-applied in the engine's statesByElement map__

This was flagged during the code review of #44580. When generating a type check block, we were interpreting any call to `$any` as an `as any` cast, even if it's part of a `PropertyRead` (e.g. `foo.$any(1)`). This is handled correctly in other parts of the compiler, but it looks like it was missed in the type checker.

PR Close#44652
This commit updates the code around the `RuntimeError` class to make it more reusable between packages (currently it's only usable inside the `core` package). Specifically:
- the error formatting logic was updated to handle cases when there is no error message provided
- there is no special Set that contains a set of error codes for which we have guides on angular.io. Instead, this is now encoded into the error code itself (making such codes negative integers). Having a separate Set makes it non-tree-shakable, which we want to avoid.
This change should allow to employ the `RuntimeError` class in other packages to further standardize this subsystem and make the errors thrown by the framework consistent.
As a part of the refactoring, the `common` package code was also updated to follow the same logic as `core`, since the `RuntimeError` class was used there as well.

When building a library, the `rootDir` option is configured to ensure
that all source files are present within the entry-point that is being
build. This imposes an extra constraint on the reference emit logic,
which does not allow emitting a reference into a source file outside of
this `rootDir`.
During the generation of type-check blocks we used to make a best-effort
estimation of whether a type reference can be emitted into the
type-check file. This check was relaxed in #42492 to support emitting
more syntax forms and type references, but this change did not consider
the `rootDir` constraint that is present in library builds. As such, the
compiler might conclude that a type reference is eligible for emit into
the type-check file, whereas in practice this would cause a failure.
This commit changes the best-effort estimation into a "preflight"
reference emit that is fully accurate as to whether emitting a type
reference is possible.

The `NgtscCompilerHost` is implemented using the `FileSystem`
abstraction of the compiler, which is implemented for tests using an
in-memory `MockFileSystem`. If the in-memory filesystem contains
symlinks, then using `NgtscCompilerHost` would not reflect their
resolved real path. Instead, the TypeScript compiler would use its
default implementation based on the real filesystem, which is unaware of
the in-memory `MockFileSystem` setup.
This change does not currently address any issues, but is being fixed
as it prevented a reproduction scenario from behaving correctly.

In certain scenarios, the compiler may have crashed with an
`Unable to write a reference` error which would be particularly hard
to diagnose. One of the primary reasons for this failure is when the
`rootDir` option is configured---typically the case for libraries---
and a source file is imported using a relative import from an external
entry-point. This would normally report TS6059 for the invalid relative
import, but the crash prevents this error from being surfaced.
This commit refactors the reference emit logic to result in an explicit
`Failure` state with a reason as to why the failure occurred. This state
is then used to report a `FatalDiagnosticException`, preventing a hard
crash.
