This commit introduces an `isStructural` flag on directive metadata, which
is `true` if the directive injects `TemplateRef` (and thus is at least
theoretically usable as a structural directive). The flag is not used for
anything currently, but will be utilized by the Language Service to offer
better autocompletion results for structural directives.
PR Close#40032
This commit adds attribute completion to the Language Service. It completes
from 3 sources:
1. inputs/outputs of directives currently present on the element
2. inputs/outputs/attributes of directives in scope for the element, that
would become present if the input/output/attribute was added
3. DOM properties and attributes
We distinguish between completion of a property binding (`[foo|]`) and a
completion in an attribute context (`foo|`). For the latter, bindings to
the attribute are offered, as well as a property binding which adds the
square bracket notation.
To determine hypothetical matches (directives which would become present if
a binding is added), directives in scope are scanned and matched against a
hypothetical version of the element which has the attribute.

This commit adds two new APIs to the `TemplateTypeChecker`:
`getPotentialDomBindings` and `getDirectiveMetadata`. Together, these will
support the Language Service in performing autocompletion of directive
inputs/outputs.

The `annotations` package in the compiler previously contained a registry
which tracks NgModule scopes for template type-checking, including unifying
all type-checking metadata across class inheritance lines.
This commit generalizes this utility and prepares it for use in the
`TemplateTypeChecker` as well, to back APIs used by the language service.

This commit expands the autocompletion capabilities of the language service
to include element tag names. It presents both DOM elements from the Angular
DOM schema as well as any components (or directives with element selectors)
that are in scope within the template as options for completion.

This commit extends the template targeting system, which determines the node
being referenced given a template position, to return additional context if
needed about the particular aspect of the node to which the position refers.
For example, a position pointing to an element node may be pointing either
to its tag name or to somewhere in the node body. This is the difference
between `<div|>` and `<div foo | bar>`.

The `deploy-to-firebase.js` tests rely on git info retrieved from the
`angular/angular` repository (via `git ls-remote ...`).
Previously, different calls to `git ls-remote ...` could return
different values if a new commit was pushed or a new branch was created
during test execution, resulting in errors ([example CI failure][1]).
This commit makes the tests more stable by memoizing the result of
`git ls-remote ...` and returning the same result for subsequent calls
with the same arguments (even if meanwhile the remote has been updated).

Projects opened in the LS are often larger in scope than the compilation
units seen by the compiler when actually building. For example, in the LS
it's not uncommon for the project to include both application as well as
test files. This can create issues when the combination of files results
in errors that are not otherwise present - for example, if test files
have inline NgModules that re-declare components (a common Angular pattern).
Such code is valid when compiling the app only (test files are excluded, so
only one declaration is seen by the compiler) or when compiling tests only
(since tests run in JIT mode and are not seen by the AOT compiler), but when
both sets of files are mixed into a single compilation unit, the compiler
sees the double declaration as an error.
This commit attempts to mitigate the problem by forcing the compiler flag
`compileNonExportedClasses` to `false` in a LS context. When tests contain
duplicate declarations, often such declarations are inline in specs and not
exported from the top level, so this flag can be used to greatly improve the
IDE experience.

When `checkTypeOfPipes` is set to `false`, the configuration is meant to
ignore the signature of the pipe's `transform` method for diagnostics.
However, we still should produce some information about the pipe for the
`TemplateTypeChecker`. This change refactors the returned symbol for
pipes so that it also includes information about the pipe's class
instance as it appears in the TCB.

The TCB utility functions used to find nodes in the TCB are currently
configured to ignore results when an ignore marker is found. However,
these ignore markers are only meant to affect diagnostics requests. The
Language Service may have a need to find nodes with diagnostic ignore
markers. The most common example of this would be finding references for
generic directives. The reference appears to the generic directive's
class appears on the type ctor in the TCB, which is ignored for
diagnostic purposes.
These functions should only skip results when the request is in the
context of a larger request for _diagnostics_. In all other cases, we
should get matches, even if a diagnostic ignore marker is encountered.
PR Close#40071
The ignore marker is only used to ignore certain nodes in the TCB for

This commit adds the ability to find references for a directive or component
from within a component template. That is, you can find component references
from the element tag `<my-c|omp></my-comp>` (where `|` is the cursor position)
as well as find references for directives that match a given attribute
`<div d|ir></div>`.

If we've already identified that we are within a `keySpan` of a node, we
exit the visitor logic early. It can be the case that we have two nodes
which technically match a given location when the end span of one node
touches the start of the keySpan for the candidate node. Because
our `isWithin` logic is inclusive on both ends, we can match both nodes.
This change exits the visitor logic once we've identified a node where
the position is within its `keySpan`.
PR Close#40047
The visitor has a check in it with the goal of preventing the structural directive
parent elements from matching when we have already found the candidate we want.
However, this code did not check to ensure that it was looking at the correct
type of node for this case and was evaluating this logic in places it shouldn't.
This special check can be more easily done by simply not traversing the
template children if we've already found a candidate on the template
node itself.

Prior to this change, the `setClassMetadata` call would be invoked
inside of an IIFE that was marked as pure. This allows the call to be
tree-shaken away in production builds, as the `setClassMetadata` call
is only present to make the original class metadata available to the
testing infrastructure. The pure marker is problematic, though, as the
`setClassMetadata` call does in fact have the side-effect of assigning
the metadata into class properties. This has worked under the assumption
that only build optimization tools perform tree-shaking, however modern
bundlers are also able to elide calls that have been marked pure so this
assumption does no longer hold. Instead, an `ngDevMode` guard is used
which still allows the call to be elided but only by tooling that is
configured to consider `ngDevMode` as constant `false` value.

Allow configuration of `relativeTo` in the `routerLink` directive. This
is related to the clearing of auxiliary routes, where you need to use
`relativeTo: route.parent` in order to clear it from the activated
auxiliary component itself. This is because `relativeTo: route` will
consume the segment that we're trying to clear, so there is really no
way to do this with routerLink at the moment.
