The Material project uses slightly different properties to the
core Angular project for specifying the different format entry-point.
This commit ensures that we map these properties correctly for both
types of project.

The `NgModule` handler generates `R3References` for its declarations, imports,
exports, and bootstrap components, based on the relative import path
between the module and the classes it's referring to. This works fine for
compilation of a .ts Program inside ngtsc, but in ngcc the import needed
in the .d.ts file may be very different to the import needed between .js
files (for example, if the .js files are flattened and the .d.ts is not).
This commit introduces a new API in the `ReflectionHost` for extracting the
.d.ts version of a declaration, and makes use of it in the
`NgModuleDecorationHandler` to write a correct expression for the `NgModule`
definition type.

This commit causes a call to setClassMetadata() to be emitted for every
type being compiled by ngtsc (every Angular type). With this metadata,
the TestBed should be able to recompile these classes when overriding
decorator information.
Testing strategy: Tests in the previous commit for
generateSetClassMetadataCall() verify that the metadata as generated is
correct. This commit enables the generation for each DecoratorHandler,
and a test is added to ngtsc_spec to verify all decorated types have
metadata generated for them.
PR Close#26860
This commit introduces generateSetClassMetadataCall(), an API in ngtsc
for generating calls to setClassMetadata() for a given declaration. The
reflection API is used to enumerate Angular decorators on the declaration,
which are converted to a format that ReflectionCapabilities can understand.
The reflection metadata is then patched onto the declared type via a call
to setClassMetadata().
This is simply a utility, a future commit invokes this utility for
each DecoratorHandler.
Testing strategy: tests are included which exercise generateSetClassMetadata
in isolation.
PR Close#26860
This commit introduces the setClassMetadata() private function, which
adds metadata to a type in a way that can be accessed via Angular's
ReflectionCapabilities. Currently, it writes to static fields as if
the metadata being added was downleveled from decorators by tsickle.
The plan is for ngtsc to emit code which calls this function, passing
metadata on to the runtime for testing purposes. Calls to this function
would then be tree-shaken away for production bundles.
Testing strategy: proper operation of this function will be an integral
part of TestBed metadata overriding. Angular core tests will fail if this
is broken.
PR Close#26860
Previously, the Directive, Injectable, and Pipe DecoratorHandlers were
directly returning @angular/compiler metadata from their analyze() steps.
This precludes returning any additional information along with that
metadata. This commit introduces a wrapper interface for these handlers,
opening the door for additional information to be returned from analyze().
Testing strategy: this is a refactor commit, existing test coverage is
sufficient.
PR Close#26860
Previously the ReflectionHost API only returned the names of decorators
and not a reference to their TypeScript Identifier. This commit adds
the identifier itself, so that a consumer can write references to the
decorator.
Testing strategy: this commit is trivial, and the functionality will be
exercised by downstream tests.
PR Close#26860
Uglify and other tree-shakers attempt to determine if the invocation
of a function is side-effectful, and remove it if so (and the result
is unused). A /*@__PURE__*/ annotation on the call site can be used
to hint to the optimizer that the invocation has no side effects and
is safe to tree-shake away.
This commit adds a 'pure' flag to the output AST function call node,
which can be used to signal to downstream emitters that a pure
annotation should be added. It also modifies ngtsc's emitter to
emit an Uglify pure annotation when this flag is set.
Testing strategy: this will be tested via its consumers, by asserting
that pure functions are translated with the correct comment.

test(ivy): mark failing test targets with fixme-ivy-jit and fixme-ivy-local tags

We are close enough to blacklist a few test targets, rather than whitelist targets to run...
Because bazel rules can be composed of other rules that don't inherit tags automatically,
I had to explicitly mark all of our ts_library and ng_module targes with "ivy-local" and
"ivy-jit" tags so that we can create a query that excludes all fixme- tagged targets even
if those targets are composed of other targets that don't inherit this tag.
This is the updated overview of ivy related bazel tags:
- ivy-only: target that builds or runs only under ivy
- fixme-ivy-jit: target that doesn't yet build or run under ivy with --compile=jit
- fixme-ivy-local: target that doesn't yet build or run under ivy with --compile=local
- no-ivy-jit: target that is not intended to build or run under ivy with --compile=jit
- no-ivy-local: target that is not intended to build or run under ivy with --compile=local

This lets Angular Bazel users install our transitive deps, rather than have to list them in their WORKSPACE file.

This commit adds generation of .ngsummary.js shims alongside .ngfactory.js
shims when generated files are enabled.
Generated .ngsummary shims contain a single, null export for every exported
class with decorators that exists in the original source files. Ivy code
does not depend on summaries, so these exist only as a placeholder to allow
them to be imported and their values passed to old APIs. This preserves
backwards compatibility.
Testing strategy: this commit adds a compiler test to verify the correct
shape and contents of the generated .ngsummary.js files.
PR Close#26495
This commit refactors the shim host to be agnostic to the shims being
generated, and provides an API for generating additional shims besides
the .ngfactory.js. This will be used in a following commit to generate
.ngsummary.js shims.
Testing strategy: this refactor introduces no new behavior, so it's
sufficient that the existing tests for factory shim generation continue
to pass.
PR Close#26495
This simple refactor of the build rules renames the .ngfactory.js shim
generator to 'shims' instead of 'factories', in preparation for adding
.ngsummary.js shim generation.
Testing strategy: this commit does not introduce any new behavior and
merely moves files and symbols around. It's sufficient that the existing
ngtsc tests pass.
PR Close#26495
Originally, the ivy_switch mechanism used Bazel genrules to conditionally
compile one TS file or another depending on whether ngc or ngtsc was the
selected compiler. This was done because we wanted to avoid importing
certain modules (and thus pulling them into the build) if Ivy was on or
off. This mechanism had a major drawback: ivy_switch became a bottleneck
in the import graph, as it both imports from many places in the codebase
and is imported by many modules in the codebase. This frequently resulted
in cyclic imports which caused issues both with TS and Closure compilation.
It turns out ngcc needs both code paths in the bundle to perform the switch
during its operation anyway, so import switching was later abandoned. This
means that there's no real reason why the ivy_switch mechanism needed to
operate at the Bazel level, and for the ivy_switch file to be a bottleneck.
This commit removes the Bazel-level ivy_switch mechanism, and introduces
an additional TypeScript transform in ngtsc (and the pass-through tsc
compiler used for testing JIT) to perform the same operation that ngcc
does, and flip the switch during ngtsc compilation. This allows the
ivy_switch file to be removed, and the individual switches to be located
directly next to their consumers in the codebase, greatly mitigating the
circular import issues and making the mechanism much easier to use.
As part of this commit, the tag for marking switched variables was changed
from __PRE_NGCC__ to __PRE_R3__, since it's no longer just ngcc which
flips these tags. Most variables were renamed from R3_* to SWITCH_* as well,
since they're referenced mostly in render2 code.
Test strategy: existing test coverage is more than sufficient - if this
didn't work correctly it would break the hello world and todo apps.

Previously, classes that were declared via variable declarations,
rather than class declarations, were being excluded from the
parsed classes.
PR Close#26236
The most recent Angular distributions have begun to use __decorate instead of Class.decorators.
This prevents `ngcc` from recognizing the classes and then fails to perform the transform to
ivy format.
Example:
```
var ApplicationModule = /** @class */ (function () {
// Inject ApplicationRef to make it eager...
function ApplicationModule(appRef) {
}
ApplicationModule = __decorate([
NgModule({ providers: APPLICATION_MODULE_PROVIDERS }),
__metadata("design:paramtypes", [ApplicationRef])
], ApplicationModule);
return ApplicationModule;
}());
```
Now `ngcc` recognizes `__decorate([...])` declarations and performs its transform.
See FW-379
PR Close#26236
In some formats variables are declared as `var` or `let` and only
assigned a value later in the code.
The ngtsc resolver still needs to be able to resolve this value,
so the host now provides a `host.getVariableValue(declaration)`
method that can do this resolution based on the format.
The hosts make some assumptions about the layout of the
code, so they may only work in the constrained scenarios that
ngcc expects.
