Alex Rickabaugh 96d6b79ada feat(ivy): resolve references to vars in .d.ts files (#25775)
Previously, if ngtsc encountered a VariableDeclaration without an
initializer, it would assume that the variable was undefined, and
return that result.

However, for symbols exported from external modules that resolve to
.d.ts files, variable declarations are of the form:

export declare let varName: Type;

This form also lacks an initializer, but indicates the presence of an
importable symbol which can be referenced. This commit changes the
static resolver to understand variable declarations with the 'declare'
keyword and to generate references when it encounters them.

Alex Rickabaugh a0c4b2d8f0 fix(ivy): add @nocollapse when writing closure-annotated code (#25775)
Closure requires @nocollapse on Ivy definition static fields in order
to not convert them to standalone constants. However tsickle, the tool
which would ordinarily be responsible for adding @nocollapse, doesn't
properly annotate fields which are added synthetically via transforms.
So this commit adds @nocollapse by applying regular expressions against
code during the final write to disk.

Alex Rickabaugh cc29b9cf93 fix(ivy): use globally unique names for i18n constants (#25689)
Closure compiler requires that the i18n message constants of the form

const MSG_XYZ = goog.getMessage('...');

have names that are unique across an entire compilation, even if the
variables themselves are local to a given module. This means that in
practice these names must be unique in a codebase.

The best way to guarantee this requirement is met is to encode the
relative file name of the file into which the constant is being written
into the constant name itself. This commit implements that solution.

Alex Rickabaugh 38f624d7e3 feat(ivy): output diagnostics for many errors in ngtsc (#25647)
This commit takes the first steps towards ngtsc producing real
TypeScript diagnostics instead of simply throwing errors when
encountering incorrect code.

A new class is introduced, FatalDiagnosticError, which can be thrown by
handlers whenever a condition in the code is encountered which by
necessity prevents the class from being compiled. This error type is
convertable to a ts.Diagnostic which represents the type and source of
the error.

Error codes are introduced for Angular errors, and are prefixed with -99
(so error code 1001 becomes -991001) to distinguish them from other TS
errors.

A function is provided which will read TS diagnostic output and convert
the TS errors to NG errors if they match this negative error code
format.

Alex Rickabaugh 5be186035f feat(ivy): enable inheritance of factory functions in definitions (#25392)
This commit creates an API for factory functions which allows them
to be inherited from one another. To do so, it differentiates between
the factory function as a wrapper for a constructor and the factory
function in ngInjectableDefs which is determined by a default
provider.

The new form is:

factory: (t?) => new (t || SomeType)(inject(Dep1), inject(Dep2))

The 't' parameter allows for constructor inheritance. A subclass with
no declared constructor inherits its constructor from the superclass.
With the 't' parameter, a subclass can call the superclass' factory
function and use it to create an instance of the subclass.

For @Injectables with configured providers, the factory function is
of the form:

factory: (t?) => t ? constructorInject(t) : provider();

where constructorInject(t) creates an instance of 't' using the
naturally declared constructor of the type, and where provider()
creates an instance of the base type using the special declared
provider on @Injectable.

Previously the compiler compliance tests ran and built test code with

Alex Rickabaugh 13a0d527f6 fix(ivy): correctly write cross-file references (#25080)
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.

Alex Rickabaugh ed7aa1c3e5 fix(ivy): force new imports for .d.ts files (#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.

Alex Rickabaugh ed1db40322 fix(ivy): use 'typeof' and 'never' for type metadata (#24862)
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.

Alex Rickabaugh 60aeee7abf feat(ivy): selector side of ModuleWithProviders via type metadata (#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.

Alex Rickabaugh 9f20dd937a feat(ivy): give ngtsc a basic understanding of ModuleWithProviders (#24738)
This commit changes the @NgModule provider to understand that sometimes
an import will resolve to an object instead of a type, and that object
could be of the ModuleWithProviders type. In that case, the 'ngModule'
property is read, and its value used instead.

This still will not handle ModuleWithProviders references across
compilation units; that work is coming in a future PR.

The current module resolution simply attaches .ts to the import/export path, which does

With these changes, the types are a little stricter now and also not
compatible with Protractor's jasmine-like syntax. So, we have to also
use `@types/jasminewd2` for e2e tests (but not for non-e2e tests).

I also had to "augment" `@types/jasminewd2`, because the latest

`jasminewd2` version (v2.1.0) currently used by Protractor supports
passing a `done` callback to a spec.

Alex Rickabaugh 0c3738a780 feat(ivy): support templateUrl for ngtsc (#24704)
This commit adds support for templateUrl in component templates within
ngtsc. The compilation pipeline is split into sync and async versions,
where asynchronous compilation invokes a special preanalyze() phase of
analysis. The preanalyze() phase can optionally return a Promise which
will delay compilation until it resolves.

A ResourceLoader interface is used to resolve templateUrls to template
strings and can return results either synchronously or asynchronously.
During sync compilation it is an error if the ResourceLoader returns a
Promise.

Two ResourceLoader implementations are provided. One uses 'fs' to read
resources directly from disk and is chosen if the CompilerHost doesn't
provide a readResource method. The other wraps the readResource method
from CompilerHost if it's provided.

Alex Rickabaugh 104d30507a feat(ivy): able to compile @angular/core with ngtsc (#24677)
@angular/core is unique in that it defines the Angular decorators
(@Component, @Directive, etc). Ordinarily ngtsc looks for imports
from @angular/core in order to identify these decorators. Clearly
within core itself, this strategy doesn't work.

Instead, a special constant ITS_JUST_ANGULAR is declared within a
known file in @angular/core. If ngtsc sees this constant it knows
core is being compiled and can ignore the imports when evaluating
decorators.

Additionally, when compiling decorators ngtsc will often write an
import to @angular/core for needed symbols. However @angular/core
cannot import itself. This change creates a module within core to
export all the symbols needed to compile it and adds intelligence
within ngtsc to write relative imports to that module, instead of
absolute imports to @angular/core.

Alex Rickabaugh 10da6a45c6 refactor(ivy): first pass at extracting ReflectionHost for abstract reflection (#24541)
ngtsc needs to reflect over code to property compile it. It performs operations
such as enumerating decorators on a type, reading metadata from constructor
parameters, etc.

Depending on the format (ES5, ES6, etc) of the underlying code, the AST
structures over which this reflection takes place can be very different. For
example, in TS/ES6 code `class` declarations are `ts.ClassDeclaration` nodes,
but in ES5 code they've been downleveled to `ts.VariableDeclaration` nodes that
are initialized to IIFEs that build up the classes being defined.

The ReflectionHost abstraction allows ngtsc to perform these operations without
directly querying the AST. Different implementations of ReflectionHost allow
support for different code formats.

Alex Rickabaugh 1eafd04eb3 build(ivy): support alternate compilation modes to enable Ivy testing (#24056)
Bazel has a restriction that a single output (eg. a compiled version of
//packages/common) can only be produced by a single rule. This precludes
the Angular repo from having multiple rules that build the same code. And
the complexity of having a single rule produce multiple outputs (eg. an
ngc-compiled version of //packages/common and an Ivy-enabled version) is
too high.

Additionally, the Angular repo has lots of existing tests which could be
executed as-is under Ivy. Such testing is very valuable, and it would be
nice to share not only the code, but the dependency graph / build config
as well.

Thus, this change introduces a --define flag 'compile' with three potential
values. When --define=compile=X is set, the entire build system runs in a
particular mode - the behavior of all existing targets is controlled by
the flag. This allows us to reuse our entire build structure for testing
in a variety of different manners. The flag has three possible settings:

* legacy (the default): the traditional View Engine (ngc) build
* local: runs the prototype ngtsc compiler, which does not rely on global
  analysis
* jit: runs ngtsc in a mode which executes tsickle, but excludes the
  Angular related transforms, which approximates the behavior of plain
  tsc. This allows the main packages such as common to be tested with
  the JIT compiler.

Additionally, the ivy_ng_module() rule still exists and runs ngc in a mode
where Ivy-compiled output is produced from global analysis information, as
a stopgap while ngtsc is being developed.

Victor Berchet 0ebd577db4 refactor(compiler): Drop support for the deprecated `<template>`. Use `<ng-template>` instead (#22783)
BREAKING CHANGE:

The `<template>` tag was deprecated in Angular v4 to avoid collisions (i.e. when
using Web Components).

This commit removes support for `<template>`. `<ng-template>` should be used
instead.

BEFORE:

    <!-- html template -->
    <template>some template content</template>

    # tsconfig.json
    {
      # ...
      "angularCompilerOptions": {
        # ...
        # This option is no more supported and will have no effect
        "enableLegacyTemplate": [true|false]
      }
    }

Alex Rickabaugh 6e00410e1c fix(compiler-cli): annotate Ivy fields as @nocollapse in closure mode (#22691)
Closure has a transformation which turns:

Service.ngInjectableDef = ...;

into:

Service$ngInjectableDef = ...;

This transformation obviously breaks Ivy in a major way. The solution is
to annotate the fields as @nocollapse. However, Typescript appears to ignore
synthetic comments added to a node during a transformation, so the "right"
way to add these comments doesn't work.

As an interim measure, a post-processing step just before the compiled JS is
written to disk appends the correct comments with a regular expression.

Igor Minar 3f70aba272 fix(compiler-cli): disableTypeScriptVersionCheck should be applied even for older tsc versions (#22669)
Previously the flag would only disable the check in the case we tried to use newer tsc version.

In g3 we sometimes take a while to update tsc, but as a prerequisite of that Angular needs to be
updated first. This change enables us to update Angular and use it in g3 while g3 is being update
to the required tsc. Of course extra care is required when this check is disabled, but since we
control everything in g3, it's on us to get this right.

I don't see any preexisting tests for this, and I'm not sure how to write them right now.

Hans Larsen 288851c41e release: add ng update package group metadata to angular (#22482)
"ng update" supports having multiple packages as part of a group which should be updated together, meaning that e.g. calling "ng update @angular/core" would be equivalent to updating all packages of the group (that are part of the package.json already).

In order to support the grouping feature, the package.json of the version the user is updating to needs to include an "ng-update" key that points to this metadata.

The entire specification for the update workflow can be found here: 2e8b12a4ef/docs/specifications/update.md

InjectionToken can be created with an ngInjectableDef, and previously
this allowed the full expressiveness of @Injectable. However, this
requires a runtime reflection system in order to generate factories

the need for a reflection system.

Alex Rickabaugh 7ac34e42a0 feat: allow direct scoping of @Injectables to the root injector (#22185)
@Injectable() supports a scope parameter which specifies the target module.
However, it's still difficult to specify that a particular service belongs
in the root injector. A developer attempting to ensure that must either
also provide a module intended for placement in the root injector or target
a module known to already be in the root injector (e.g. BrowserModule).
Both of these strategies are cumbersome and brittle.

Instead, this commit adds a token APP_ROOT_SCOPE which provides a
straightforward way of targeting the root injector directly, without
requiring special knowledge of modules within it.

Alex Rickabaugh 235a235fab feat: change @Injectable() to support tree-shakeable tokens (#22005)
This commit bundles 3 important changes, with the goal of enabling tree-shaking
of services which are never injected. Ordinarily, this tree-shaking is prevented
by the existence of a hard dependency on the service by the module in which it
is declared.

Firstly, @Injectable() is modified to accept a 'scope' parameter, which points
to an @NgModule(). This reverses the dependency edge, permitting the module to
not depend on the service which it "provides".

Secondly, the runtime is modified to understand the new relationship created
above. When a module receives a request to inject a token, and cannot find that
token in its list of providers, it will then look at the token for a special
ngInjectableDef field which indicates which module the token is scoped to. If
that module happens to be in the injector, it will behave as if the token
itself was in the injector to begin with.

Thirdly, the compiler is modified to read the @Injectable() metadata and to
generate the special ngInjectableDef field as part of TS compilation, using the
PartialModules system.

Additionally, this commit adds several unit and integration tests of various
flavors to test this change.
