When building a list of pending tasks for callers of whenStable(),
Testability will copy data about the task into a new object, in order to
avoid leaking references to tasks.
This change copies more properties from Tasks into the list of pending
tasks, as well as a reference to Task.data to give callers more
information about the tasks that are pending.
Specifically, this also copies runCount and task ID, which are needed in
order for callers to know when a given task is repeating.

Previously the compiler compliance tests ran and built test code with
real dependencies on @angular/core and @angular/common. This meant that
any changes to the compiler would result in long rebuild processes
for tests to rerun.
This change removes those dependencies and causes test code to be built
against the fake_core stub of @angular/core that the ngtsc tests use.
This change also removes the dependency on @angular/common entirely, as
locality means it's possible to reference *ngIf without needing to link
to an implementation.

Before the `ngDevMode` had to be set explicitly or it would throw
an exception at runtime. This changes it so that if `ngDevModu` is
`undefined` than we default to `ngDevMode = true`. In other words
unless the developer has explicitly asked to make a prodution build
by setting `ngDevMode = false` as compilation constant, the default
is `ngDevMode = true`.
This also fixes a minor bug where the setup code would read
`global['ngDevMode']` but all other code would read `global.ngDevMode`.
This would cause issues with closure compiler since the
reading of the `ngDevMode` must be consistent.

Update XMB placeholders(<ph>) to include the original value on top of an

This change makes sure that we have the original text, but it *DOES NOT*

ngtsc used to assume that all .d.ts dependencies (that is, third party
packages) were imported via an absolute module path. It turns out this
assumption isn't valid; some build tools allow relative imports of
other compilation units.
In the absolute case, ngtsc assumes (and still does) that all referenced
types are available through the entrypoint from which an @NgModule was
imported. This commit adds support for relative imports, in which case
ngtsc will use relative path resolution to determine the imports.

There is a bug in the existing handling for cross-file references.
Suppose there are two files, module.ts and component.ts.
component.ts declares two components, one of which uses the other.
In the Ivy model, this means the component will get a directives:
reference to the other in its defineComponent call.
That reference is generated by looking at the declared components
of the module (in module.ts). However, the way ngtsc tracks this
reference, it ends up comparing the identifier of the component
in module.ts with the component.ts file, detecting they're not in
the same file, and generating a relative import.
This commit changes ngtsc to track all identifiers of a reference,
including the one by which it is declared. This allows toExpression()
to correctly decide that a local reference is okay in component.ts.
PR Close#25080
When ngtsc encounters a reference to a type (for example, a Component
type listed in an NgModule declarations array), it traces the import
of that type and attempts to determine the best way to refer to it.
In the event the type is defined in the same file where a reference
is being generated, the identifier of the type is used. If the type
was imported, ngtsc has a choice. It can use the identifier from the
original import, or it can write a new import to the module where the
type came from.
ngtsc has a bug currently when it elects to rely on the user's import.
When writing a .d.ts file, the user's import may have been elided as
the type was not referred to from the type side of the program. Thus,
in .d.ts files ngtsc must always assume the import may not exist, and
generate a new one.
In .js output the import is guaranteed to still exist, so it's
preferable for ngtsc to continue using the existing import if one is
available.
This commit changes how @angular/compiler writes type definitions, and
allows it to use a different expression to write a type definition than
is used to write the value. This allows ngtsc to specify that types in
type definitions should always be imported. A corresponding change to
the staticallyResolve() Reference system allows the choice of which
type of import to use when generating an Expression from a Reference.

It includes two modes of support for forward reference resolution -
a foreign function resolver which understands deeply nested forward
references in expressions that are being statically evaluated, and

Both will be useful in the future, but for now only unwrapForwardRef()

Fixes#25018.
Instantiating a NgModuleRef from NgModuleFactory reuses the NgModuleDefinition if it is already present. However the NgModuleDefinition has a providers array which modified when tree shakable providers are instantiated. This corrupts the provider definitions the next time the same factory is used to create a new NgModuleRef - Two provider definitions can end up with the same index anf the injector could potentially return a completely wrong object for a provider token.
This scenario is more likely on the server where the same NgModuleFactory is reused across requests.
The fix clones the cached NgModuleDefinition so that any tree shakable providers added later do not affect the cached copy.

Ivy definition types have a generic type which specifies the return
type of the factory function. For example:
static ngDirectiveDef<NgForOf, '[ngFor][ngForOf]'>
However, in this case NgForOf itself has a type parameter <T>. Thus,
writing the above is incorrect.
This commit modifies ngtsc to understand the genericness of NgForOf and
to write the following:
static ngDirectiveDef<NgForOf<any>, '[ngFor][ngForOf]'>

Previously ngtsc would use a tuple of class types for listing metadata
in .d.ts files. For example, an @NgModule's declarations might be
represented with the type:
[NgIf, NgForOf, NgClass]
If the module had no declarations, an empty tuple [] would be produced.
This has two problems.
1. If the class type has generic type parameters, TypeScript will
complain that they're not provided.
2. The empty tuple type is not actually legal.
This commit addresses both problems.
1. Class types are now represented using the `typeof` operator, so the
above declarations would be represented as:
[typeof NgIf, typeof NgForOf, typeof NgClass].
Since typeof operates on a value, it doesn't require generic type
arguments.
2. Instead of an empty tuple, `never` is used to indicate no metadata.

Previously, when translating an assignment expression (e.g. x = 3), the
translator would always print the statement as X = Y. However, if the
expression is included in a larger expression (X = (Y = Z)), the
translator would print "X = Y = Z" without regard for the outer
expression context.
Now, the translator understands when it's printing an expression
statement (X = Y;) vs an expression in a larger context (X = (Y = Z);)
and encapsulates the latter in parentheses.

Previously, references had the concept of an identifier, but would not
properly detect whether the identifier should be used or not when
generating an expression. This change fixes that logic.
Additionally, now whenever an identifier resolves to a reference (even
one imported from another module) as part of resolving an expression,
the reference is updated to use that identifier. This ensures that for
a class Foo declared in foo.ts, but referenced in an expression in
bar.ts, the Reference returned includes the identifier from bar.ts,
meaning that writing an expression in bar.ts for the Reference will not
generate an import.

ngInjectorDef.imports is generated from @NgModule.imports plus
@NgModule.exports. A problem arises as a result, because @NgModule
exports contain not only other modules (which will have ngInjectorDef
fields), but components, directives, and pipes as well. Because of
locality, it's difficult for the compiler to filter these out at
build time.
It's not impossible, but for now filtering them out at runtime will
allow testing of the compiler against complex applications.

@NgModule()s get compiled to two fields: ngModuleDef and ngInjectorDef.
Both fields contain imports, as both selector scopes and injectors have
the concept of composed units of configuration. Previously these fields
were generated by static resolution of imports and exports in metadata.
Support for ModuleWithProviders requires they be generated differently.
ngModuleDef's imports/exports are generated as resolved lists of types,
whereas ngInjectorDef's imports should reflect the raw expressions that
the developer wrote in the metadata.
This change modifies the NgModule handler and properly copies raw nodes
for the imports and exports into the ngInjectorDef.

PR Close#24862
Within an @NgModule it's common to include in the imports a call to
a ModuleWithProviders function, for example RouterModule.forRoot().
The old ngc compiler was able to handle this pattern because it had
global knowledge of metadata of not only the input compilation unit
but also all dependencies.
The ngtsc compiler for Ivy doesn't have this knowledge, so the
pattern of ModuleWithProviders functions is more difficult. ngtsc
must be able to determine which module is imported via the function
in order to expand the selector scope and properly tree-shake
directives and pipes.
This commit implements a solution to this problem, by adding a type
parameter to ModuleWithProviders through which the actual module
type can be passed between compilation units.
The provider side isn't a problem because the imports are always
copied directly to the ngInjectorDef.
