Currently if an embedded view contains projected nodes, its `rootNodes` array will include `null` instead of the root nodes inside the projection slot. This manifested itself in one of the Material unit tests where we stamp out a template and then move its `rootNodes` into the overlay container.

For efficiency reasons we often put several different data types (`RNode`, `LView`, `LContainer`,
`StylingContext`) in same location in `LView`. This is because we don't want to pre-allocate
space
for it because the storage is sparse. This file contains utilities for dealing with such data
types.
How do we know what is stored at a given location in `LView`.
- `Array.isArray(value) === false` => `RNode` (The normal storage value)
- `Array.isArray(value) === true` => than the `value[0]` represents the wrapped value.
- `typeof value[TYPE] === 'object'` => `LView`
- This happens when we have a component at a given location
- `typeof value[TYPE] === 'number'` => `StylingContext`
- This happens when we have style/class binding at a given location.
- `typeof value[TYPE] === true` => `LContainer`
- This happens when we have `LContainer` binding at a given location.
NOTE: it is assumed that `Array.isArray` and `typeof` operations are very efficient.

`LView`, `LContainer`, `StylingContext` are all arrays which wrap either
an `HTMLElement`, `LView`, `LContainer`, `StylingContext`. It is often
necessary to retrieve the correct type of element from the location
which means that we often have to wrap the arrays. Logically it makes
more sense if the thing which we are wrapping is at `0` location. Also
it may be more performant since data is more local which may result in
more L2 cache hits in CPU.

This change contains conditionally attached classes which provide human readable (debug) level
information for `LView`, `LContainer` and other internal data structures. These data structures
are stored internally as array which makes it very difficult during debugging to reason about the

change the cost of access, therefore this patching should not have significant if any impact in

In certain configurations (such as the g3 repository) which have lots of
small compilation units as well as strict dependency checking on generated
code, ngtsc's default strategy of directly importing directives/pipes into
components will not work. To handle these cases, an additional mode is
introduced, and is enabled when using the FileToModuleHost provided by such
compilation environments.
In this mode, when ngtsc encounters an NgModule which re-exports another
from a different file, it will re-export all the directives it contains at
the ES2015 level. The exports will have a predictable name based on the
FileToModuleHost. For example, if the host says that a directive Foo is
from the 'root/external/foo' module, ngtsc will add:
```
export {Foo as ɵng$root$external$foo$$Foo} from 'root/external/foo';
```
Consumers of the re-exported directive will then import it via this path
instead of directly from root/external/foo, preserving strict dependency
semantics.

This change is kind of similar to #27466, but instead of ensuring that
these shims can be generated, we also need to make sure that developers
are able to also use the factory shims like with `ngc`.
This issue is now surfacing because we have various old examples which
are now also built with `ngtsc` (due to the bazel migration). On case insensitive
platforms (e.g. windows) these examples cannot be built because ngtsc fails
the app imports a generated shim file (such as the factory shim files).
This is because the `GeneratedShimsHostWrapper` TypeScript host uses
the `getCanonicalFileName` method in order to check whether a given
file/module exists in the generator file maps. e.g.
```
// Generator Map:
'C:/users/paul/_bazel_paul/lm3s4mgv/execroot/angular/packages/core/index.ngfactory.ts' =>
'C:/users/paul/_bazel_paul/lm3s4mgv/execroot/angular/packages/core/index.ts',
// Path passed into `fileExists`
C:/users/paul/_bazel_paul/lm3s4mgv/execroot/angular/packages/core/index.ngfactory.ts
// After getCanonicalFileName (notice the **lower-case drive name**)
c:/users/paul/_bazel_paul/lm3s4mgv/execroot/angular/packages/core/index.ngfactory.ts
```
As seen above, the generator map does not use the canonical file names, as well as
TypeScript internally does not pass around canonical file names. We can fix this by removing
the manual call to `getCanonicalFileName` and just following TypeScript internal-semantics.

Prior to this commit, the timing of `ViewChild`/`ContentChild` query
resolution depended on the results of each query. If any results
for a particular query were nested inside embedded views (e.g.
*ngIfs), that query would be resolved after change detection ran.
Otherwise, the query would be resolved as soon as nodes were created.
This inconsistency in resolution timing had the potential to cause
confusion because query results would sometimes be available in
ngOnInit, but sometimes wouldn't be available until ngAfterContentInit
or ngAfterViewInit. Code depending on a query result could suddenly
stop working as soon as an *ngIf or an *ngFor was added to the template.
With this commit, users can dictate when they want a particular
`ViewChild` or `ContentChild` query to be resolved with the `static`
flag. For example, one can mark a particular query as `static: false`
to ensure change detection always runs before its results are set:
```ts
@ContentChild('foo', {static: false}) foo !: ElementRef;
```
This means that even if there isn't a query result wrapped in an
*ngIf or an *ngFor now, adding one to the template later won't change
the timing of the query resolution and potentially break your component.
Similarly, if you know that your query needs to be resolved earlier
(e.g. you need results in an ngOnInit hook), you can mark it as
`static: true`.
```ts
@ViewChild(TemplateRef, {static: true}) foo !: TemplateRef;
```
Note: this means that your component will not support *ngIf results.
If you do not supply a `static` option when creating your `ViewChild` or
`ContentChild` query, the default query resolution timing will kick in.
Note: This new option only applies to `ViewChild` and `ContentChild`
queries, not `ViewChildren` or `ContentChildren` queries, as those types
already resolve after CD runs.

Currently if developers use call expressions in their static
class members ([like we do in Angular](https://github.com/angular/angular/blob/master/packages/core/src/change_detection/differs/keyvalue_differs.ts#L121)),
the metadata that is generated for flat modules is invalid. This
is because the metadata bundler logic currently does not handle
call expressions in static class members and the symbol references
are not rewritten to avoid relative paths in the bundle.
Static class members using a call expression are not relevant for
the ViewEngine AOT compilation, but it is problematic that the
bundled metadata references modules using their original relative
path. This means that the bundled metadata is no longer encapsulated
and depends on other emitted files to be emitted in the proper place.
These incorrect relative paths can now cause issues where NGC
looks for the referenced symbols in the incorrect path. e.g.
```
src/
| lib/
| index.ts -> References the call expression using `../../di`
```
Now the metadata looks like that:
```
node_modules/
| @angular/
-- | core/
-- -- | core.metadata.json -> Says that the call expr. is in `../../di`.
| di/
```
Now if NGC tries to use the metadata files and create the summary files,
NGC resolves the call expression to the `node_modules/di` module. Since
the "unexpected" module does not contain the desired symbol, NGC will
error out.
We should fix this by ensuring that we don't ship corrupted metadata
to NPM which contains relative references that can cause such
failures (other imports can be affected as well; it depends on what
modules the developer has installed and how we import our call
expressions).

BREAKING CHANGE
Previous to this change, when a control was reset, value and status change
events would be emitted before the control was reset to pristine. As a
result, if one were to check a control's pristine state in a valueChange
listener, it would appear that the control was still dirty after reset.
This change delays emission of value and status change events until after
controls have been marked pristine. This means the pristine state will be
reset as expected if one checks in a listener.
Theoretically, there could be applications depending on checking whether a
control *used to be dirty*, so this is marked as breaking. In these cases,
apps should cache the state on the app side before calling reset.

The ultimate goal of this commit is to make use of fileNameToModuleName to
get the module specifier to use when generating an import, when that API is
available in the CompilerHost that ngtsc is created with.
As part of getting there, the way in which ngtsc tracks references and
generates import module specifiers is refactored considerably. References
are tracked with the Reference class, and previously ngtsc had several
different kinds of Reference. An AbsoluteReference represented a declaration
which needed to be imported via an absolute module specifier tracked in the
AbsoluteReference, and a RelativeReference represented a declaration from
the local program, imported via relative path or referred to directly by
identifier if possible. Thus, how to refer to a particular declaration was
encoded into the Reference type _at the time of creation of the Reference_.
This commit refactors that logic and reduces Reference to a single class
with no subclasses. A Reference represents a node being referenced, plus
context about how the node was located. This context includes a
"bestGuessOwningModule", the compiler's best guess at which absolute
module specifier has defined this reference. For example, if the compiler
arrives at the declaration of CommonModule via an import to @angular/common,
then any references obtained from CommonModule (e.g. NgIf) will also be
considered to be owned by @angular/common.
A ReferenceEmitter class and accompanying ReferenceEmitStrategy interface
are introduced. To produce an Expression referring to a given Reference'd
node, the ReferenceEmitter consults a sequence of ReferenceEmitStrategy
implementations.
Several different strategies are defined:
- LocalIdentifierStrategy: use local ts.Identifiers if available.
- AbsoluteModuleStrategy: if the Reference has a bestGuessOwningModule,
import the node via an absolute import from that module specifier.
- LogicalProjectStrategy: if the Reference is in the logical project
(is under the project rootDirs), import the node via a relative import.
- FileToModuleStrategy: use a FileToModuleHost to generate the module
specifier by which to import the node.
Depending on the availability of fileNameToModuleName in the CompilerHost,
then, a different collection of these strategies is used for compilation.

Previously, ngtsc would throw an error if two decorators were matched on
the same class simultaneously. However, @Injectable is a special case, and
it appears frequently on component, directive, and pipe classes. For pipes
in particular, it's a common pattern to treat the pipe class also as an
injectable service.
ngtsc actually lacked the capability to compile multiple matching
decorators on a class, so this commit adds support for that. Decorator
handlers (and thus the decorators they match) are classified into three
categories: PRIMARY, SHARED, and WEAK.
PRIMARY handlers compile decorators that cannot coexist with other primary
decorators. The handlers for Component, Directive, Pipe, and NgModule are
marked as PRIMARY. A class may only have one decorator from this group.
SHARED handlers compile decorators that can coexist with others. Injectable
is the only decorator in this category, meaning it's valid to put an
@Injectable decorator on a previously decorated class.
WEAK handlers behave like SHARED, but are dropped if any non-WEAK handler
matches a class. The handler which compiles ngBaseDef is WEAK, since
ngBaseDef is only needed if a class doesn't otherwise have a decorator.
Tests are added to validate that @Injectable can coexist with the other
decorators and that an error is generated when mixing the primaries.
PR Close#28523
In the past, @Injectable had no side effects and existing Angular code is
therefore littered with @Injectable usage on classes which are not intended
to be injected.
A common example is:
@Injectable()
class Foo {
constructor(private notInjectable: string) {}
}
and somewhere else:
providers: [{provide: Foo, useFactory: ...})
Here, there is no need for Foo to be injectable - indeed, it's impossible
for the DI system to create an instance of it, as it has a non-injectable
constructor. The provider configures a factory for the DI system to be
able to create instances of Foo.
Adding @Injectable in Ivy signifies that the class's own constructor, and
not a provider, determines how the class will be created.
This commit adds logic to compile classes which are marked with @Injectable
but are otherwise not injectable, and create an ngInjectableDef field with
a factory function that throws an error. This way, existing code in the wild
continues to compile, but if someone attempts to use the injectable it will
fail with a useful error message.
In the case where strictInjectionParameters is set to true, a compile-time
error is thrown instead of the runtime error, as ngtsc has enough
information to determine when injection couldn't possibly be valid.

With #28594 we refactored the `@angular/compiler` slightly to
allow opting out from external symbol re-exports which are
enabled by default.
Since symbol re-exports only benefit projects which have a
very strict dependency enforcement, external symbols should
not be re-exported by default as this could grow the size of
factory files and cause unexpected behavior with Angular's
AOT symbol resolving (e.g. see: #25644).
Note that the common strict dependency enforcement for source
files does still work with external symbol re-exports disabled,
but there are also strict dependency checks that enforce strict
module dependencies also for _generated files_ (such as the
ngfactory files). This is how Google3 manages it's dependencies
and therefore external symbol re-exports need to be enabled within
Google3.
Also "ngtsc" also does not provide any way of using external symbol
re-exports, so this means that with this change, NGC can partially

Previously, using a pipe in an input binding on an ng-template would
evaluate the pipe in the context of node that was processed before the
template. This caused the retrieval of e.g. ChangeDetectorRef to be
incorrect, resulting in one of the following bugs depending on the
template's structure:
1. If the template was at the root of a view, the previously processed
node would be the component's host node outside of the current view.
Accessing that node in the context of the current view results in a crash.
2. For templates not at the root, the ChangeDetectorRef injected into the
pipe would correspond with the previously processed node. If that node
hosts a component, the ChangeDetectorRef would not correspond with the
view that the ng-template is part of.
The solution to the above problem is two-fold:
1. Template compilation is adjusted such that the template instruction
is emitted before any instructions produced by input bindings, such as
pipes. This ensures that pipes are evaluated in the context of the
template's container node.
2. A ChangeDetectorRef can be requested for container nodes.

During analysis, the `ComponentDecoratorHandler` passes the component
template to the `parseTemplate()` function. Previously, there was little or
no information about the original source file, where the template is found,
passed when calling this function.
Now, we correctly compute the URL of the source of the template, both
for external `templateUrl` and in-line `template` cases. Further in the
in-line template case we compute the character range of the template
in its containing source file; *but only in the case that the template is
a simple string literal*. If the template is actually a dynamic value like
an interpolated string or a function call, then we do not try to add the
originating source file information.
The translator that converts Ivy AST nodes to TypeScript now adds these
template specific source mappings, which account for the file where
the template was found, to the templates to support stepping through the
template creation and update code when debugging an Angular application.
Note that some versions of TypeScript have a bug which means they cannot
support external template source-maps. We check for this via the
`canSourceMapExternalTemplates()` helper function and avoid trying to
add template mappings to external templates if not supported.

There are some differences in how ivy maps template source
compared to View Engine. In this commit we recreate the View Engine
tests for ivy.
PR Close#28055
Previously the call to `extractSourceMap()` would only work if the
`//#sourceMappingURL ...` was the last line of the file. This doesn't
work if the code is JIT evaluated as the comment is actually the last
line in the body of a function, wrapped by curly-braces.
PR Close#28055
When testing JIT code, it is useful to be able to access the
generated JIT source. Previously this is done by spying on the
global `Function` object, to capture the code when it is being
evaluated. This is problematic because you can only capture
the body of the function, and not the arguments, which messes
up line and column positions for source mapping for instance.
Now the code that generates and then evaluates JIT code is
wrapped in a `JitEvaluator` class, making it possible to provide
a mock implementation that can capture the generated source of
the function passed to `executeFunction(fn: Function, args: any[])`.
PR Close#28055
When we resolve a component `templateUrl` we copy the contents of the
resolved template file into the `template` property.
Previously we would then remove the `templateUrl` to indicate that
the component has been resolved. But this meant that we no longer had
access to the URL of the original template file. This is essential for
diagnostics messages about the template compilation.
Now the existence of the `template` property overrides the existence of
`templateUrl`, which allows us to keep the `templateUrl` property.
PR Close#28055
In order to support source mapping of templates, we need
to be able to tokenize the template in its original context.
When the template is defined inline as a JavaScript string
in a TS/JS source file, the tokenizer must be able to handle
string escape sequences, such as `\n` and `\"` as they
appear in the original source file.
This commit teaches the lexer how to unescape these
sequences, but only when the `escapedString` option is
set to true. Otherwise there is no change to the tokenizing
behaviour.
PR Close#28055
The lexer that does the tokenizing can now process only a part the source
string, by passing a `range` property in the `options` argument. The
locations of the nodes that are tokenized will now take into account the
position of the span in the context of the original source string.
This `range` option is, in turn, exposed from the template parser as well.
Being able to process parts of files helps to enable SourceMap support
when compiling inline component templates.
PR Close#28055
When we added the strict null checks, the lexer had some `!`
operators added to prevent the compilation from failing.

This commit consolidates the options that can modify the
parsing of text (e.g. HTML, Angular templates, CSS, i18n)
into an AST for further processing into a single `options`

This makes the code cleaner and more readable, but also
enables us to support further options to parsing without
triggering wide ranging changes to code that should not
be affected by these new options. Specifically, it will let
us pass information about the placement of a template
that is being parsed in its containing file, which is essential
for accurate SourceMap processing.

Prior to this change in Ivy we had strict check that disabled non-unique #localRefs usage within a given template. While this limitation was technically present in View Engine, in many cases View Engine neglected this restriction and as a result, some apps relied on a fact that multiple non-unique #localRefs can be defined and utilized to query elements via @ViewChild(ren) and @ContentChild(ren). In order to provide better compatibility with View Engine, this commit removes existing restriction.
As a part of this commit, are few tests were added to verify VE and Ivy compatibility in most common use-cases where multiple non-unique #localRefs were used.

Currently external static symbols which are referenced by AOT
compiler generated code, will be re-exported in the corresponding
`.ngfactory` files.
This way of handling the symbol resolution has been introduced in
favor of avoding dynamically generated module dependencies. This
behavior therefore avoids any strict dependency failures.
Read more about a particular scenario here: https://github.com/angular/angular/issues/25644#issuecomment-458354439
Now with `ngtsc`, this behavior has changed since `ngtsc` just
introduces these module dependencies in order to properly reference
the external symbol from its original location (also eliminating the need
for factories). Similarly we should provide a way to use the same
behavior with `ngc` because the downside of using the re-exported symbol
resolution is that user-code transformations (e.g. the `ngInjectableDef`
metadata which is added to the user source code), can resolve external
symbols to previous factory symbol re-exports. This is a critical issue
because it means that the actual JIT code references factory files in order
to access external symbols. This means that the generated output cannot
shipped to NPM without shipping the referenced factory files.
A specific example has been reported here: https://github.com/angular/angular/issues/25644#issue-353554070

When we first started writing tests for Ivy, we did not yet have a
compatible compiler. For this reason, we set up the Ivy runtime tests
to run with generated code that we wrote by hand (instead of real code
generated by the compiler).
Now that we have a working Ivy compiler and TestBed infrastructure
that is compatible with Ivy, we should start writing integration
tests that leverage them (no more handwritten generated code!). This
will prevent bugs where the compiler code and runtime code become
out of sync (which is easy if they are tested separately). And
eventually, we should migrate all the existing runtime tests in
"core/test/render3" to TestBed and ngtsc.
To kick off this effort, this commit migrates some existing tests
from "core/test/render3/exports_spec.ts" and saves them in a new file
with the same name in the "core/test/acceptance" folder.

i18n instructions create text nodes dynamically and save them between bindings and the expando block in `LView`. e.g., they try to create the following order in `LView`.
```
| -- elements -- | -- bindings -- | -- dynamic i18n text -- | -- expando (dirs, injectors) -- |
```
Each time a new text node is created, it is pushed to the end of the array and the `expandoStartIndex` marker is incremented, so the section begins slightly later. This happens in `allocExpando`.
This is fine if no directives have been created yet. The end of the array will be in the "dynamic text node" section.
| -- elements -- | -- bindings -- | -- dynamic i18n text -- |
However, this approach doesn't work if dynamic text nodes are created after directives are matched (for example when the directive uses host bindings). In that case, there are already directives and injectors saved in the "expando" section. So pushing to the end of `LView` actually pushes after the expando section. What we get is this:
```
| -- elements -- | -- bindings -- | -- dynamic i18n text -- | -- expando -- | -- dynamic i18n text-- |
```
In this case, the `expandoStartIndex` shouldn't be incremented because we are not inserting anything before the expando section (it's now after the expando section). But because it is incremented in the code right now, it's now pointing to an index in the middle of the expando section.
This PR fixes that so that we only increment the `expandoStartIndex` if nothing was pushed into the expando section.

Ivy allows Components to extend Directives (but not the other way around) and as a result we may have Component and Directive annotations present at the same time. The logic that resolves annotations to pick the necessary one didn't take this into account and as a result Components were recognized as Directives (and vice versa) in case of inheritance. This change updates the resolution logic by picking known annotation that is the nearest one (in inheritance tree) and compares it with expected type.
