Currently the `RecursiveAstVisitor` that is part of the template expression
parser does not _always_ properly pass through the context that can be
specified when visting a given expression. Only a handful of AST types
pass through the context while others are accidentally left out. This causes
unexpected and inconsistent behavior and basically makes the `context`
parameter not usable if the type of template expression is not known.
e.g. the template variable assignment migration currently depends on
the `RecursiveAstVisitor` but sometimes breaks if developers use
things like conditionals in their template variable assignments.

To provide some context: The implicit receiver is part of the
parsed Angular template AST. Any property reads in bindings,
interpolations etc. read from a given object (usually the component
instance). In that case there is an _implicit_ receiver which can also
be specified explicitly by just using `this`.
e.g.
```html
<ng-template>{{this.myProperty}}</ng-template>
```
This works as expected in Ivy and View Engine, but breaks in case the
implicit receiver is not used for property reads. For example:
```html
<my-dir [myFn]="greetFn.bind(this)"></my-dir>
```
In that case the `this` will not be properly translated into the generated
template function code because the Ivy compiler currently always treats
the `ctx` variable as the implicit receiver. This is **not correct** and breaks
compatibility with View Engine. Rather we need to ensure that we retrieve
the root context for the standalone implicit receiver similar to how it works
for property reads (as seen in the example above with `this.myProperty`)
Note that this requires some small changes to the `expression_converter`
because we only want to generate the `eenextContent()` instruction if the
implicit receiver is _actually_ used/needed. View Engine determines if that is the case by recursively walking through the converted output AST and
checking for usages of the `o.variable('_co')` variable ([see here][ve_check]). This would work too for Ivy, but involves most likely more code duplication
since templates are isolated in different functions and it another pass
through the output AST for every template expression.

is inherited from its superclass, then the factory function of the

with ngcc. This is causing unexpected behavior because decorator

helper function can be resolved to an actual function with body, such
that it won't be considered as foreign function. Instead, a reflection

With View engine it was possible to declare multiple projection

e.g.
```html

```
Using `ViewContainerRef#createComponent` allowed projecting
nodes into one of the projection defs (through index)
This no longer works with Ivy as the `projectionDef` instruction only
retrieves a list of selectors instead of also retrieving entries for
reserved projection slots which appear when using the default
selector multiple times (as seen above).
In order to fix this issue, the Ivy compiler now passes all
projection slots to the `projectionDef` instruction. Meaning that
there can be multiple projection slots with the same wildcard
selector. This allows multi-slot projection as seen in the
example above, and it also allows us to match the multi-slot node
projection order from View Engine (to avoid breaking changes).

The main reason for this is that when a developer is writing a schematic they shouldn't need to compute the offset based if a file has a BOM or not and is handled out of the box.
Example
```ts
recorder.insertLeft(5, 'true');
```
However this is unfortunate in the case if a ts SourceFile is used and one uses `getWidth` and `getStart` method they will already be offset by 1, which at the end it results in a double offset and hence the problem.

Two issues with DebugNode/DebugElement in Ivy were causing problems in user
tests.
1. The DebugNodes returned by Ivy were not actually instances of DebugNode.
This was due to an issue with the Ivy switch logic in debug_node.ts.
The declaration of the exported DebugNode reference was set to
`DebugNode__PRE_R3__ as any`. The cast prevented the Ivy switch transform
from detecting this as a switchable declaration. The transform cannot handle
arbitrary syntax, and exports *must* be of the form "const x = y__PRE_R3__;"
or they will not work. The cast to any in this case was not needed, so this
commit removes it.
2. DebugNodes returned by Ivy multiple times for the same element were not
reference-identical. This was previously considered a minor breaking change
in Ivy, but testing has shown that users depend on referential equality of
DebugNodes. This commit caches a DebugNode on a DOM node when first creating
it, to allow returning the same instance in subsequent operations.

Due to sanitization being stored as a temp/global value between

`i18nAttributes` instructions always occur after the element instruction. This means that we need to treat `i18n-` attributes differently.

The R3TargetBinder "binds" an Angular template AST, computing semantic
information regarding the template and making it accessible.
One of the binding passes previously had a bug, where for the following
template:
<div *ngIf="foo as foo"></div>
which desugars to:
<ng-template ngIf [ngIf]="foo" let-foo="ngIf">
<div></div>
</ng-template>
would have the `[ngIf]` binding processed twice - in both the scope which
contains the `<ng-template>` and the scope inside the template. The bug
arises because during the latter, `foo` is a variable defined by `let-foo`,
and so the R3TargetBinder would incorrectly learn that `foo` inside `[ngIf]`
maps to that variable.
This commit fixes the bug by only processing inputs, outputs, and
templateAttrs from `Template`s in the outer scope.

Plural ICU expressions depend on the locale (different languages have different plural forms). Until now the locale was hard coded as `en-US`.
For compatibility reasons, if you use ivy with AOT and bootstrap your app with `bootstrapModule` then the `LOCALE_ID` token will be set automatically for ivy, which is then used to get the correct plural form.
If you use JIT, you need to define the `LOCALE_ID` provider on the module that you bootstrap.
For `TestBed` you can use either `configureTestingModule` or `overrideProvider` to define that provider.
If you don't use the compat mode and start your app with `renderComponent` you need to call `ɵsetLocaleId` manually to define the `LOCALE_ID` before bootstrap. We expect this to change once we start adding the new i18n APIs, so don't rely on this function (there's a reason why it's a private export).

This is a new feature of the Ivy TestBed.
A common user pattern is to test one component with another. This is
commonly done by creating a `TestFixture` component which exercises the
main component under test.
This pattern is more difficult if the component under test is declared in an
NgModule but not exported. In this case, overriding the module is necessary.
In g3 (and View Engine), it's possible to use an NgSummary to override the
recompilation of a component, and depend on its AOT compiled factory. The
way this is implemented, however, specifying a summary for a module
effectively overrides much of the TestBed's other behavior. For example, the
following is legal:
```typescript
TestBed.configureTestingModule({
declarations: [FooCmp, TestFixture],
imports: [FooModule],
aotSummaries: [FooModuleNgSummary],
});
```
Here, `FooCmp` is declared in both the testing module and in the imported
`FooModule`. However, because the summary is provided, `FooCmp` is not
compiled within the context of the testing module, but _is_ made available
for `TestFixture` to use, even if it wasn't originally exported from
`FooModule`.
This pattern breaks in Ivy - because summaries are a no-op, this amounts
to a true double declaration of `FooCmp` which raises an error.
Fixing this in user code is possible, but is difficult to do in an
automated or backwards compatible way. An alternative solution is
implemented in this PR.
This PR attempts to capture the user intent of the following previously
unsupported configuration:
```typescript
TestBed.configureTestingModule({
declarations: [FooCmp, TestFixture],
imports: [FooModule],
});
```
Note that this is the same as the configuration above in Ivy, as the
`aotSummaries` value provided has no effect.
The user intent here is interpreted as follows:
1) `FooCmp` is a pre-existing component that's being used in the test
(via import of `FooModule`). It may or may not be exported by this
module.
2) `FooCmp` should be part of the testing module's scope. That is, it
should be visible to `TestFixture`. This is because it's listed in
`declarations`.
This feature effectively makes the `TestBed` testing module special. It's
able to declare components without compiling them, if they're already
compiled (or configured to be compiled) in the imports. And crucially, the
behavior matches the first example with the summary, making Ivy backwards
compatible with View Engine for tests that use summaries.

DEPRECATION:
platform-webworker has been around since the initial release of Angular
version 2. It began as an experiment to leverage Angular's rendering
architecture and try something different: to run an entire web application
in a web worker.
We've learned a lot from this experiment, and have come to the conclusion
that pushing entire applications to run in a web worker is not a recipe for
success for most applications. This is due to a number of unresolved issues,
including:
* Poor or non-existent support for web worker APIs in web crawlers/indexers.
* Poor support in build and bundling tooling.
As a result, as of Angular version 8, we are deprecating the
`platform-webworker` APIs in Angular. This consists of both NPM packages,
`@angular/platform-webworker` and `@angular/platform-webworker-dynamic`.
Going forward, we will focus our efforts related to web workers around their
primary use case of offloading CPU-intensive but not critical work.

With Ivy, injecting a `ViewContainerRef` for a `<ng-container>` element
results in two comments generated in the DOM. One comment as host
element for the `ElementContainer` and one for the generated `LContainer`
which is needed for the created `ViewContainerRef`.
This is problematic as developers expect the same anchor element for
the `LContainer` and the `ElementContainer` in order to be able to move
the host element of `<ng-container>` without leaving the actual
`LContainer` anchor element at the original location.
This worked differently in View Engine and various applications might
depend on the behavior where the `ViewContainerRef` shares the anchor
comment node with the host comment node of the `<ng-container>`. For
example `CdkTable` from `@angular/cdk` moves around the host element of
a `<ng-container>` and also expects embedded views to be inserted next
to the moved `<ng-container>` host element.

BREAKING CHANGE
In PR #19558, we fixed a bug in `TestBed.overrideProvider` where
eager providers were not being instantiated correctly. However,
it turned out that since this bug had been around for quite a bit,
many apps were relying on the broken behavior where the providers
would not be instantiated. To assist in the transition, the
`TestBed.deprecatedOverrideProvider` method was temporarily
introduced to mimic the old behavior so that apps would have a
longer time period to migrate their code.
2 years and 3 versions later, it is time to remove the temporary
method. This commit removes `TestBed.deprecatedOverrideProvider`
altogether. Any usages of `TestBed.deprecatedOverrideProvider`
should be replaced with `TestBed.overrideProvider`. This may mean
that providers that were not created before will now be instantiated,
which could mean that your tests need to provide more mocks or stubs
for the dependencies of the newly instantiated providers.

Context:
As part of the `test_docs_examples_ivy` job, we run 5 concurrent builds
on each VM (each for a different example/project). Additionally, all
example projects share the same `node_modules/` (via a symlink to
`aio/tools/examples/shared/node_modules/`), so all concurrent builds
operate on the same files.
Previously, we pre-ran ngcc with `--properties module` to process the
fesm5 bundles. Since we have switched to es2015 in 661a57d9e, we now
need the esm2015 bundles. As a result, the initial ngcc run is
redundant and ngcc runs again during each build (to process the fesm2015
bundles). Since there are 5 concurrent builds, we often end up with
multiple ngcc instances processing the same package and trying to write
to the same directories at the same time, causing a
`file already exists` error
This commit fixes it by pre-processing the esm2015 bundles, so there is
no need to re-run ngcc during each concurrent build.

A structural directive can specify a template guard for an input, such that
the type of that input's binding can be narrowed based on the guard's return
type. Previously, such template guards could only be methods, of which an
invocation would be inserted into the type-check block (TCB). For `NgIf`,
the template guard narrowed the type of its expression to be `NonNullable`
using the following declaration:
```typescript
export declare class NgIf {
static ngTemplateGuard_ngIf<E>(dir: NgIf, expr: E): expr is NonNullable<E>
}
```
This works fine for usages such as `*ngIf="person"` but starts to introduce
false-positives when e.g. an explicit non-null check like
`*ngIf="person !== null"` is used, as the method invocation in the TCB
would not have the desired effect of narrowing `person` to become
non-nullable:
```typescript
if (NgIf.ngTemplateGuard_ngIf(directive, ctx.person !== null)) {
// Usages of `ctx.person` within this block would
// not have been narrowed to be non-nullable.
}
```
This commit introduces a new strategy for template guards to allow for the
binding expression itself to be used as template guard in the TCB. Now,
the TCB generated for `*ngIf="person !== null"` would look as follows:
```typescript
if (ctx.person !== null) {
// This time `ctx.person` will successfully have
// been narrowed to be non-nullable.
}
```
This strategy can be activated by declaring the template guard as a
property declaration with `'binding'` as literal return type.
See #30235 for an example where this led to a false positive.

In View engine it is possible to instantiate a service that that has no
`@Injectable` decorator as long as it satisfies one of:
1) It has no dependencies and so a constructor with no parameters.
This is already supported in Ivy.
2) It has no constructor of its own and sub-classes a service which has
dependencies but has its own `@Injectable` decorator. This second
scenario was broken in Ivy.
In Ivy, previous to this commit, if a class to be instantiated did not have
its own `@Injectable` decorator and did not provide a constructor of
its own, then it would be created using `new` with no arguments -
i.e. falling back to the first scenario.
After this commit Ivy correctly uses the `ngInjectableDef` inherited
from the super-class to provide the `factory` for instantiating the
sub-class.

In some cases where multiple navigations happen to the same URL, the router will not process a given URL. In those cases, we fall into logic that resets state for the next navigation. One piece of this resetting is to set the `browserUrlTree` to the most recent `urlAfterRedirects`i.
However, there was bug in this logic because in some cases the `urlAfterRedirects` is a stale value. This happens any time a URL won't be processed, and the previous URL will also not be processed. This creates unpredictable behavior, not the least of which ends up being a broken `back` button.
This PR kicks off new navigations with the current value the router assumes is in the browser. All the logic around how to handle future navigations is based on this value compared to the current transition, so it's important to kick off all new navigations with the current value so in the edge case described above we don't end up with an old value being set into `browserUrlTree`.

To support skipping analysis of a file containing a component
we need to know that none of the declarations that might affect
its ngtsc compilation have not changed. The files that we need to
check are those that contain classes from the `CompilationScope`
of the component. These classes are already tracked in the
`LocalModuleScopeRegistry`.
This commit modifies the `IvyCompilation` class to record the
files that are in each declared class's `CompilationScope` via
a new method, `recordNgModuleScopeDependencies()`, that is called
after all the handlers have been "resolved".
Further, if analysis is skipped for a declared class, then we need
to recover the analysis from the previous compilation run. To
support this, the `IncrementalState` class has been updated to
expose the `MetadataReader` and `MetadataRegistry` interfaces.
This is included in the `metaRegistry` object to capture these analyses,
and also in the `localMetaReader` as a fallback to use if the

to tell whether the given call expression actually causes the specified
arrow function to be executed synchronously or not. In order to be able

check for a synchronous query usage. If so, we set the query timing to

When working out the dependencies between entry-points
ngcc must parse the import statements and then resolve the

Previously ngcc used the node.js `require.resolve`, with some
hacking to resolve modules. This change refactors the `DependencyHost`
to use a new custom `ModuleResolver`, which is optimized for this use
case.

Previously, under certain circumstances, `NgZone#onMicrotaskEmpty` could
emit while a `$digest` was in progress, thus triggering another
`$digest`, which in turn would throw a `$digest already in progress`
error. Furthermore, throwing an error from inside the `onMicrotaskEmpty`
subscription would result in unsubscribing and stop triggering further
`$digest`s, when `onMicrotaskEmpty` emitted.
Usually, emitting while a `$digest` was already in progress was a result
of unintentionally running some part of AngularJS outside the Angular
zone, but there are valid (if rare) usecases where this can happen
(see #24680 for details).
This commit addresses the issue as follows:
- If a `$digest` is in progress when `onMicrotaskEmpty` emits, do not
trigger another `$digest` (to avoid the error). `$evalAsync()` is used
instead, to ensure that the bindings are evaluated at least once more.
- Since there is still a high probability that the situation is a result
of programming error (i.e. some AngularJS part running outside the
Angular Zone), a warning will be logged, but only if the app is in

ngtsc generates type constructors which infer the type of a directive based
on its inputs. Previously, a bug existed where this inference would fail in
the case of 'any' input values. For example, the inference of NgForOf fails

T[] = any

desirable.
The fix is to assign generic types in type constructors a default type of
'any', which TypeScript uses instead of {} when inference fails.

The proposed ES dynamic import() is now supported by the Angular CLI and the
larger toolchain. This renders the `loadChildren: string` API largely
redundant, as import() is far more natural, is less error-prone, and is
standards compliant. This commit deprecates the `string` form of
`loadChildren` in favor of dynamic import().
DEPRECATION:
When defining lazy-loaded route, Angular previously offered two options for
configuring the module to be loaded, both via the `loadChildren` parameter
of the route. Most Angular developers are familiar withthe `string` form of
this API. For example, the following route definition configures Angular to
load a `LazyModule` NgModule from `lazy-route/lazy.module.ts`:
```
[{
path: 'lazy',
loadChildren: 'lazy-route/lazy.module#LazyModule',
}]
```
This "magic string" configuration was previously necessary as there was
no dynamic module loading standard on the web. This has changed with the
pending standardization of dynamic `import()` expressions, which are now
supported in the Angular CLI and in web tooling in general. `import()`
offers a more natural and robust solution to dynamic module loading. The
above example can be rewritten to use dynamic `import()`:
```
[{
path: 'lazy',
loadChildren: () => import('./lazy-route/lazy.module').then(mod => mod.LazyModule),
}]
```
This form of lazy loading offers significant advantages in terms of:
* type checking via TypeScript
* simplicity of generated code
* future potential to run natively in supporting browsers
(see: [caniuse: dynamic import()](https://caniuse.com/#feat=es6-module-dynamic-import))
As a result, Angular is deprecating the `loadChildren: string` syntax in
favor of ES dynamic `import()`. An automatic migration will run during
`ng upgrade` to convert your existing Angular code to the new syntax.

This commit provides a replacement for `$location`. The new service is written in Angular, and can be consumed into existing applications by using the downgraded version
of the provider.
Prior to this addition, applications upgrading from AngularJS to Angular could get into a situation where AngularJS wanted to control the URL, and would often parse or se
rialize the URL in a different way than Angular. Additionally, AngularJS was alerted to URL changes only through the `$digest` cycle. This provided a buggy feedback loop
from Angular to AngularJS.
With this new `LocationUpgradeProvider`, the `$location` methods and events are provided in Angular, and use Angular APIs to make updates to the URL. Additionally, change
s to the URL made by other parts of the Angular framework (such as the Router) will be listened for and will cause events to fire in AngularJS, but will no longer attempt
to update the URL (since it was already updated by the Angular framework).
This centralizes URL reads and writes to Angular and should help provide an easier path to upgrading AngularJS applications to Angular.

This PR adds an API to retrieve the value of `history.state`. This will be useful and needed to provide a backwards-compatible `Location` service that can emulate AngularJS's `$location` service since we will need to be able to read the state data in order to produce AngularJS location transition events.

ngtsc previously could attempt to reuse the main ts.Program twice. This
occurred when template type-checking was enabled and then an incremental
build was performed. This breaks a TypeScript invariant - ts.Programs can

The creation of the template type-checking program reuses the main program,
rendering it moot. Then, on the next incremental build the main program

This commit fixes the issue by reusing the template type-checking program
from the previous run on the next incremental build. Since under normal
circumstances the files in the type-checking program aren't changed, this
should be just as fast.

The compiler uses metadata to represent what it statically knows about
various expressions in a program. Occasionally, expressions in the program
for which metadata is extracted may contain sub-expressions which are not
representable in metadata. One such construct is an arrow function.
The compiler does not always need to understand such expressions completely.
For example, for a provider defined with `useValue`, the compiler does not
need to understand the value at all, only the outer provider definition. In
this case, the compiler employs a technique known as "expression lowering",
where it rewrites the provider expression into one that can be represented
in metadata. Chiefly, this involves extracting out the dynamic part (the
`useValue` expression) into an exported constant.
Lowering is applied through a heuristic, which considers the containing
statement as well as the field name of the expression.
Previously, this heuristic was not completely accurate in the case of
route definitions and the `loadChildren` field, which is lowered. If the
route definition using `loadChildren` existed inside a decorator invocation,
lowering was performed correctly. However, if it existed inside a standalone
variable declaration with an export keyword, the heuristic would conclude
that lowering was unnecessary. For ordinary providers this is true; however
the compiler attempts to fully understand the ROUTES token and thus even if
an array of routes is declared in an exported variable, any `loadChildren`
expressions within still need to be lowered.
This commit enables lowering of already exported variables under a limited
set of conditions (where the initializer expression is of a specific form).
This should enable the use of `loadChildren` in route definitions.

Previously, Template.templateAttrs was introduced to capture attribute
bindings which originated from microsyntax (e.g. bindings in *ngFor="...").
This means that a Template node can have two different structures, depending
on whether it originated from microsyntax or from a literal <ng-template>.
In the literal case, the node behaves much like an Element node, it has
attributes, inputs, and outputs which determine which directives apply.
In the microsyntax case, though, only the templateAttrs should be used
to determine which directives apply.
Previously, both the t2_binder and the TemplateDefinitionBuilder were using
the wrong set of attributes to match directives - combining the attributes,
inputs, outputs, and templateAttrs of the Template node regardless of its
origin. In the TDB's case this wasn't a problem, since the TDB collects a
global Set of directives used in the template, so it didn't matter whether
the directive was also recognized on the <ng-template>. t2_binder's API
distinguishes between directives on specific nodes, though, so it's more
sensitive to mismatching.
In particular, this showed up as an assertion failure in template type-
checking in certain cases, when a directive was accidentally matched on
a microsyntax template element and also had a binding which referenced a
variable declared in the microsyntax. This resulted in the type-checker
attempting to generate a reference to a variable that didn't exist in that
scope.
The fix is to distinguish between the two cases and select the appropriate
set of attributes to match on accordingly.
Testing strategy: tested in the t2_binder tests.

Instead, a far more performant approach is to augment the program with a
single type-checking file, into which all TCBs are generated. Additionally,
type constructors are also inlined into this file.
This is not always possible - both TCBs and type constructors can sometimes
require inlining into user code, particularly if bound generic type
parameters are present, so the approach taken is actually a hybrid. These
operations are inlined if necessary, but are otherwise generated in a single
file.
It is critically important that the original program also include an empty
version of the type-checking file, otherwise the shape of the two programs
will be different and TypeScript will throw away all the old program
information. This leads to a painfully slow type checking pass, on the same
order as the original program creation. A shim to generate this file in the
original program is therefore added.
Testing strategy: this commit is largely a refactor with no externally
observable behavioral differences, and thus no tests are needed.

This commit adds support in the template type-checking engine for handling
the logical not operation and the safe navigation operation.
Safe navigation in particular is tricky, as the View Engine implementation
has a rather inconvenient flaw. View Engine checks a safe navigation
operation `a?.b` as:
```typescript
(a != null ? a!.b : null as any)
```
The type of this expression is always 'any', as the false branch of the
ternary has type 'any'. Thus, using null-safe navigation throws away the
type of the result, and breaks type-checking for the rest of the expression.
A flag is introduced in the type-checking configuration to allow Ivy to
mimic this behavior when needed.
Testing strategy: TCB tests included.
PR Close#29698
View Engine's implementation of naive template type-checking is less
advanced than the current Ivy implementation. As a result, Ivy catches lots
of typing bugs which VE does not. As a result, it's necessary to tone down
the Ivy template type-checker in the default case.
This commit introduces a mechanism for doing that, by passing a config to
the template type-checking engine. Through this configuration, particular
checks can be loosened or disabled entirely.

Previously the template type-checking code only considered the metadata of
directive classes actually referenced in the template. If those directives
had base classes, any inputs/outputs/etc of the base classes were not
tracked when generating the TCB. This resulted in bindings to those inputs
being incorrectly attributed to the host component or element.
This commit uses the new metadata package to follow directive inheritance
chains and use the full metadata for a directive for TCB generation.
Testing strategy: Template type-checking tests included.
PR Close#29698
Previously, metadata registration (the recording of collected metadata
during analysis of directives, pipes, and NgModules) was only used to
produce the `LocalModuleScope`, and thus was handled by the
`LocalModuleScopeRegistry`.
However, the template type-checker also needs information about registered
directives, outside of the NgModule scope determinations. Rather than
reuse the scope registry for an unintended purpose, this commit introduces
new abstractions for metadata registration and lookups in a separate
'metadata' package, which the scope registry implements.
This paves the way for a future commit to make use of this metadata for the
template type-checking system.
Testing strategy: this commit is a refactoring which introduces no new
functionality, so existing tests are sufficient.
PR Close#29698
Previously, bindings to [class] and [style] were treated like any other
property binding. That is, they would result in type-checking code that
attempted to write directly to .class or .style on the element node.
This is incorrect, however - the mapping from Angular's [class] and [style]
onto the DOM properties is non-trivial.
For now, this commit avoids the issue by only checking the expressions
themselves and not the assignment to the element properties.

Previously the template type-checking engine processed templates in a linear
manner, and could not handle '#' references within a template. One reason
for this is that '#' references are non-linear - a reference can be used
before its declaration. Consider the template:
```html
{{ref.value}}
<input #ref>
```
Accommodating this required refactoring the type-checking code generator to
be able to produce Type Check Block (TCB) code non-linearly. Now, each
template is processed and a list of TCB operations (`TcbOp`s) are created.
Non-linearity is modeled via dependencies between operations, with the
appropriate protection in place for circular dependencies.

Previous to this change, we assumed embedded views could only be created after
their parent template node had completed processing. As a result, we only set
up query logic for containers after directives on the node were created.
However, this assumption didn't take into account the case where a directive
on a template node could create views in its constructor.
This commit fixes query logic to work with views created in constructors.
In that case, we need to create a query container before the new view is
rendered so query results in the view aren't lost. But since the query container
is created before directives have completed processing, we also have to ensure
that query results gathered later on the template node are inserted before that
query container. Otherwise, query results in embedded views will clobber query
results on template nodes.
This splice mode may be slightly slower than the normal matching for queries on
containers, but we should only fall back to this strategy in the edge case where
views are created in constructors. (We should encourage developers to create
views in ngOnInit instead).

Previously, the `build-with-ivy` script could be used to build the `aio`
project with Ivy (once it had been prepared with `ivy-ngcc`, etc.) and

As a result, it was not useful for running other commands (e.g. unit/e2e

This commit renames the script to `switch-to-ivy` and employs a
different model (similar to `ng-packages-installer`), where the project
is setup to run in Ivy mode and then all subsequent commands are
executed in that mode (until restored).
Since this is currently only used on CI, there is no automatic way to
switch back to non-ivy mode (but it could be implemented in the future
if needed).
Finally, the script now modifies `src/tsconfig.app/json` instead of

as the AngularCompilerProgram also collects metadata for referenced
component stylesheets which aren't necessarily present. e.g. in a CLI
project the component can reference a Sass file. It's not guaranteed

In order to be able to use prompts in a migration schematic, we need to
take advantage of the "inquirer" package which is also used by the CLI

If a component has its definition set by defineComponent (as opposed to
JIT getter), then it will generate a factory that uses directiveInject()
to retrieve its dependencies. This can be problematic in test code because

Plural ICU expressions depend on the locale (different languages have different plural forms). Until now the locale was hard coded as `en-US`.
For compatibility reasons, if you use ivy with AOT and bootstrap your app with `bootstrapModule` then the `LOCALE_ID` token will be set automatically for ivy, which is then used to get the correct plural form.
If you use JIT, you need to define the `LOCALE_ID` provider on the module that you bootstrap.
For `TestBed` you can use either `configureTestingModule` or `overrideProvider` to define that provider.
If you don't use the compat mode and start your app with `renderComponent` you need to call `ɵsetLocaleId` manually to define the `LOCALE_ID` before bootstrap.

Queries can technically be also accessed within component templates
e.g.
```html

```
In that case the query with the property "myQuery" is accessed
statically and needs to be marked with `static: true`. There are
other edge cases that need to be handled as the template property
read doesn't necessarily resolve to the actual query property.
For example:
```html
<foo #myQuery></foo>
<my-comp [binding]="myQuery"></my-comp>

In this scenario the binding doesn't refer to the actual query
because the template reference variable takes precedence. The
query doesn't need to be marked with "static: true" this time.
This commit ensures that the `static-query` migration schematic
now handles this cases properly. Also template property reads
that access queries from within a `<ng-template>` are ignored
as these can't access the query before the view has been initialized.

The `template-var-assignment` schematic currently complains if someone
assigns a value to a template variable. This will no longer work with Ivy, but
it should be totally fine to update a property of the template variable if it refers

Now, one can add an `@alias` tag to API docs, which tells dgeni that this
API element (usually a `const`) is really just an alias for some API element
defined elsewhere.
Dgeni will then look up this API element and copy over the properties from
the alias to the current doc.
For example, we would like to privately export an Enum from `@angular/core`
but then publicly export this from `@angular/common`:
**packages/core/private_exports.ts**
```ts
/**
* Description of this document.
*/
export enum ɵSomeEnum { ... }
```
**packages/common/public_api.ts**
```ts
import {ɵSomeEnum} from '@angular/core';
/**
* @alias core/ɵSomeEnum
*/
export const SomeEnum = ɵSomeEnum;
```
In the generated docs there will be a page for `common/SomeEnum`, which
will be rendered as an enum, rather than a const, showing the description
extracted from the `core/ɵSomeEnum`.
---
The implementation of this feature required some refactoring of the other
processing:
1. Previously `ɵ` prefixed exports were not even considered.
2. Due to 1. some processors needed to have guards added to ignore such
private exports (`addMetadataAliases` and `checkContentRules`).
3. The processing of package pages had to be reworked (and split) so that
it picked up the aliased export docs after their alias proeprties had
been copied.

Prior to this change, a module's imports and exports would be used verbatim
as an injectors' imports. This is detrimental for tree-shaking, as a
module's exports could reference declarations that would then prevent such

Since an injector actually only needs NgModule references as its imports,
we may safely filter out any declarations from the list of module exports.
This makes them eligible for tree-shaking once again.

Prior to this change, all module metadata would be included in the
`defineNgModule` call that is set as the `ngModuleDef` field of module

imports and exports that is used for computing the transitive module
scope in JIT environments, preventing those references from being
tree-shaken for production builds.
This change moves the metadata for scope computations to a pure function
call that patches the scope references onto the module type. Because the
function is marked pure, it may be tree-shaken out during production builds
such that references to declarations and exports are dropped, which in turn
allows for tree-shaken any declaration that is not otherwise referenced.

In ES2015, classes could have been emitted as a variable declaration
initialized with a class expression. In certain situations, an intermediary
variable suffixed with `_1` is present such that the variable
declaration's initializer becomes a binary expression with its rhs being
the class expression, and its lhs being the identifier of the intermediate
variable. This structure was not recognized, resulting in such classes not
being considered as a class in `Esm2015ReflectionHost`.
As a consequence, the analysis of functions/methods that return a
`ModuleWithProviders` object did not take the methods of such classes into
account.
Another edge-case with such intermediate variable was that static
properties would not be considered as class members. A testcase was added

Currently, ngtsc decides to use remote scoping if the compilation of a
component may create a cyclic import. This happens if there are two
components in a scope (say, A and B) and A directly uses B. During
compilation of B ngtsc will then note that if B were to use A, a cycle would
be generated, and so it will opt to use remote scoping for B.

are actually required, for future cycle tracking. This commit expands that
usage to not trigger remote scoping unless B actually does consume A in its

When an @NgModule is imported more than once in the testing module (for
example it appears in the imports of more than one module, or if it's
literally listed multiple times), then TestBed had a bug where the
providers for the module would be overridden many times.
This alone was problematic but would not break tests. However, the original
value of the providers field of the ngInjectorDef was saved each time, and
restored in the same order. Thus, if the provider array was [X], and
overrides were applied twice, then the override array would become
[X, X'] and then [X, X', X, X']. However, on the second override the state
[X, X'] would be stored as original. The array would then be restored to
[X] and then [X, X'].
Each test, therefore, would continue to double the size of the providers
array for the module, eventually exhausting the browser's memory.

and refrain from applying them more than once.

Previously, several `ngtsc` and `ngcc` APIs dealing with class
declaration nodes used inconsistent types. For example, some methods of
the `DecoratorHandler` interface expected a `ts.Declaration` argument,
but actual `DecoratorHandler` implementations specified a stricter
`ts.ClassDeclaration` type.
As a result, the stricter methods would operate under the incorrect
assumption that their arguments were of type `ts.ClassDeclaration`,
while the actual arguments might be of different types (e.g. `ngcc`
would call them with `ts.FunctionDeclaration` or
`ts.VariableDeclaration` arguments, when compiling ES5 code).
Additionally, since we need those class declarations to be referenced in
other parts of the program, `ngtsc`/`ngcc` had to either repeatedly
check for `ts.isIdentifier(node.name)` or assume there was a `name`
identifier and use `node.name!`. While this assumption happens to be
true in the current implementation, working around type-checking is
error-prone (e.g. the assumption might stop being true in the future).
This commit fixes this by introducing a new type to be used for such
class declarations (`ts.Declaration & {name: ts.Identifier}`) and using
it consistently throughput the code.

Sometimes, in ESM5 code, aliases to exported variables are used internally
to refer to the exported value. This prevented some analysis from being
able to match up a reference to an export to the actual export itself.
For example in the following code:
```
var HttpClientXsrfModule = /** @class */ (function () {
function HttpClientXsrfModule() {
}
HttpClientXsrfModule_1 = HttpClientXsrfModule;
HttpClientXsrfModule.withOptions = function (options) {
if (options === void 0) { options = {}; }
return {
ngModule: HttpClientXsrfModule_1,
providers: [],
};
};
var HttpClientXsrfModule_1;
HttpClientXsrfModule = HttpClientXsrfModule_1 = tslib_1.__decorate([
NgModule({
providers: [],
})
], HttpClientXsrfModule);
return HttpClientXsrfModule;
}());
```
We were not able to tell that the `ngModule: HttpClientXsrfModule_1` property
assignment was actually meant to refer to the `function HttpClientXrsfModule()`
declaration. This caused the `ModuleWithProviders` processing to fail.

Prior to this change, we always recompile all Components/Directives/Pipes even if they were AOT-compiled and had no overrides. This is causing problems in case we try to recompile a Component with "templateUrl" or "styleUrls" (which were already resolved in case of AOT) and generally this unnecessary work that TestBed was doing is not required. This commit adds extra logic to check whether a Component/Directive/Pipe already have compiled NG def (like ngComponentDef) and whether there are no overrides present - in this case recompilation is skipped. Recompilation is also skipped in case a Component/Directive has only Provider overrides - in this situation providers resolver function is patched to reflect overrides. Provider overrides are very common in g3, thus this code path ensures no full recompilation.

This fix is for a bug in the ngtsc PartialEvaluator, which statically
evaluates expressions.
Sometimes, evaluating a reference requires resolving a function which is
declared in another module, and thus no function body is available. To
support this case, the PartialEvaluator has the concept of a foreign
function resolver.
This allows the interpretation of expressions like:
const router = RouterModule.forRoot([]);
even though the definition of the 'forRoot' function has no body. In
ngtsc today, this will be resolved to a Reference to RouterModule itself,
via the ModuleWithProviders foreign function resolver.
However, the PartialEvaluator also associates any Identifiers in the path
of this resolution with the Reference. This is done so that if the user
writes
const x = imported.y;
'x' can be generated as a local identifier instead of adding an import for
'y'.
This was at the heart of a bug. In the above case with 'router', the
PartialEvaluator added the identifier 'router' to the Reference generated
(through FFR) to RouterModule.
This is not correct. References that result from FFR expressions may not
have the same value at runtime as they do at compile time (indeed, this is
not the case for ModuleWithProviders). The Reference generated via FFR is
"synthetic" in the sense that it's constructed based on a useful
interpretation of the code, not an accurate representation of the runtime
value. Therefore, it may not be legal to refer to the Reference via the
'router' identifier.
This commit adds the ability to mark such a Reference as 'synthetic', which
allows the PartialEvaluator to not add the 'router' identifier down the
line. Tests are included for both the PartialEvaluator itself as well as the
resultant buggy behavior in ngtsc overall.

Currently if an Angular library has multiple unnamed module re-exports, NGC will
generate incorrect metdata if the project is using the flat-module bundle option.
e.g.
_public-api.ts_
```ts
export * from '@mypkg/secondary1';
export * from '@mypkg/secondary2';
```
There are clearly two unnamed re-exports in the `public-api.ts` file. NGC right now
accidentally overwrites all previous re-exports with the last one. Resulting in the
generated metadata only containing a reference to `@mypkg/secondary2`.
This is problematic as it is common for primary library entry-points to have
multiple re-exports (e.g. Material re-exporting all public symbols; or flex-layout
exporting all public symbols from their secondary entry-points).
Currently Angular Material works around this issue by manually creating
a metadata file that declares the re-exports from all unnamed re-exports.
(see: https://github.com/angular/material2/blob/master/tools/package-tools/build-release.ts#L78-L85)
This workaround works fine currently, but is no longer easily integrated when

before any directives are instantiated so that directive code can rely on any inline

BREAKING CHANGE:
Certain elements (like `<tr>` or `<col>`) require parent elements to be of a certain type by the HTML specification
(ex. <tr> can only be inside <tbody> / <thead>). Before this change Angular template parser was auto-correcting
"invalid" HTML using the following rules:
- `<tr>` would be wrapped in `<tbody>` if not inside `<tbody>`, `<tfoot>` or `<thead>`;
- `<col>` would be wrapped in `<colgroup>` if not inside `<colgroup>`.
This meachanism of automatic wrapping / auto-correcting was problematic for several reasons:
- it is non-obvious and arbitrary (ex. there are more HTML elements that has rules for parent type);
- it is incorrect for cases where `<tr>` / `<col>` are at the root of a component's content, ex.:
```html
<projecting-tr-inside-tbody>
<tr>...</tr>
</projecting-tr-inside-tbody>

This fixes an issue with commit b6f6b117. In this commit, default imports
processed in a type-to-value conversion were recorded as non-local imports
with a '*' name, and the ImportManager generated a new default import for
them. When transpiled to ES2015 modules, this resulted in the following
correct code:
import i3 from './module';
// somewhere in the file, a value reference of i3:
{type: i3}
However, when the AST with this synthetic import and reference was
transpiled to non-ES2015 modules (for example, to commonjs) an issue
appeared:
var module_1 = require('./module');
{type: i3}
TypeScript renames the imported identifier from i3 to module_1, but doesn't
substitute later references to i3. This is because the import and reference
are both synthetic, and never went through the TypeScript AST step of
"binding" which associates the reference to its import. This association is
important during emit when the identifiers might change.
Synthetic (transformer-added) imports will never be bound properly. The only
possible solution is to reuse the user's original import and the identifier
from it, which will be properly downleveled. The issue with this approach
(which prompted the fix in b6f6b117) is that if the import is only used in a
type position, TypeScript will mark it for deletion in the generated JS,
even though additional non-type usages are added in the transformer. This
again would leave a dangling import.
To work around this, it's necessary for the compiler to keep track of
identifiers that it emits which came from default imports, and tell TS not
to remove those imports during transpilation. A `DefaultImportTracker` class
is implemented to perform this tracking. It implements a
`DefaultImportRecorder` interface, which is used to record two significant
pieces of information:
* when a WrappedNodeExpr is generated which refers to a default imported
value, the ts.Identifier is associated to the ts.ImportDeclaration via
the recorder.
* when that WrappedNodeExpr is later emitted as part of the statement /
expression translators, the fact that the ts.Identifier was used is
also recorded.
Combined, this tracking gives the `DefaultImportTracker` enough information
to implement another TS transformer, which can recognize default imports
which were used in the output of the Ivy transform and can prevent them
from being elided. This is done by creating a new ts.ImportDeclaration for
the imports with the same ts.ImportClause. A test verifies that this works.

refer to the *value declaration* of the call expression. e.g. the symbol refers to the
import declaration which imports the external function. This means that we currently

Sometimes declarations are not exported publicly but are exported under
a private name. In this case, rather than adding a completely new
export to the entry point, we should create an export that aliases the
private name back to the original public name.
This is important when the typings files have been rolled-up using a tool
such as the [API Extractor](https://api-extractor.com/). In this case
the internal type of an aliased private export will be removed completely
from the typings file, so there is no "original" type to re-export.
For example:
If there are the following TS files:
**entry-point.ts**
```ts
export {Internal as External} from './internal';
```
**internal.ts**
```ts
export class Internal {
foo(): void;
}
```
Then the API Extractor might roll up the .d.ts files into:
```ts
export declare class External {
foo(): void;
}
```
In this case ngcc should add an export so the file looks like:
```ts
export declare class External {
foo(): void;
}
export {External as Internal};
```

Previously, when the NgModule scope resolver discovered semantic errors
within a users NgModules, it would throw assertion errors. TODOs in the
codebase indicated these should become ts.Diagnostics eventually.
Besides producing better-looking errors, there is another reason to make
this change asap: these assertions were shadowing actual errors, via an
interesting mechanism:
1) a component would produce a ts.Diagnostic during its analyze() step
2) as a result, it wouldn't register component metadata with the scope
resolver
3) the NgModule for the component references it in exports, which was
detected as an invalid export (no metadata registering it as a
component).
4) the resulting assertion error would crash the compiler, hiding the
real cause of the problem (an invalid component).
This commit should mitigate this problem by converting scoping errors to
proper ts.Diagnostics. Additionally, we should consider registering some
marker indicating a class is a directive/component/pipe without actually
requiring full metadata to be produced for it, which would allow suppression
of errors like "invalid export" for such invalid types.

Foo from"). This commit moves the type-to-value logic to a separate file and
expands it to cover the default import case. Doing this also required
augmenting the ImportManager to track default as well as non-default import
generation. The APIs were made a little cleaner at the same time.

In the TypeScript compiler API, emit() can be performed either on a single
ts.SourceFile or on the entire ts.Program simultaneously.
ngtsc previously used whole-program emit, which was convenient to use while
spinning up the project but has a significant drawback: it causes a type
checking operation to occur for the whole program, including .d.ts files.
In large Bazel environments (such as Google's codebase), an ngtsc invocation
can have a few .ts files and thousands of .d.ts inputs. This unwanted type
checking is therefore a significant drain on performance.
This commit switches ngtsc to emit each .ts file individually, avoiding the
unwanted type checking.

When processing a JavaScript program, TS may come across a symbol that has
been imported from a TypeScript typings file.
In this case the compiler may pass the ReflectionHost a `prototype` symbol
as an export of the class.

code in `Esm5ReflectionHost.reflectMembers()` to crash.

For the template type checking to work correctly, it needs to know
what attributes are bound to expressions or directives, which may
require expressions in the template to be evaluated in a different
scope.
In inline templates, there are attributes that are now marked as
"Template" attributes. We need to ensure that the template
type checking code looks at these "bound" attributes as well as the
"input" attributes.
PR Close#29041
The content projection mechanism is static, in that it only looks at the static
template nodes before directives are matched and change detection is run.
When you have a selector-based content projection the selection is based
on nodes that are available in the template.
For example:
```
<ng-content selector="[some-attr]"></ng-content>
```
would match
```
<div some-attr="..."></div>
```
If you have an inline-template in your projected nodes. For example:
```
<div *ngIf="..." some-attr="..."></div>
```
This gets pre-parsed and converted to a canonical form.
For example:
```
<ng-template [ngIf]="...">
<div some-attr=".."></div>
</ng-template>
```
Note that only structural attributes (e.g. `*ngIf`) stay with the `<ng-template>`
node. The other attributes move to the contained element inside the template.
When this happens in ivy, the ng-template content is removed
from the component template function and is compiled into its own
template function. But this means that the information about the
attributes that were on the content are lost and the projection
selection mechanism is unable to match the original
`<div *ngIf="..." some-attr>`.
This commit adds support for this in ivy. Attributes are separated into three
groups (Bindings, Templates and "other"). For inline-templates the Bindings
and "other" types are hoisted back from the contained node to the `template()`
instruction, so that they can be used in content projection matching.

ngtsc occasionally converts a type reference (such as the type of a
parameter in a constructor) to a value reference (argument to a
directiveInject call). TypeScript has a bad habit of sometimes removing
the import statement associated with this type reference, because it's a

ngtsc has cyclic import detection, to determine when adding an import to a
directive or pipe would create a cycle. However, this detection must also
account for already inserted imports, as it's possible for both directions
of a circular import to be inserted by Ivy (as opposed to at least one of
those edges existing in the user's program).
This commit fixes the circular import detection for components to take into
consideration already added edges. This is difficult for one critical
reason: only edges to files which will *actually* be imported should be
considered. However, that depends on which directives & pipes are used in
a given template, which is currently only known by running the
TemplateDefinitionBuilder during the 'compile' phase. This is too late; the
decision whether to use remote scoping (which consults the import graph) is
made during the 'resolve' phase, before any compilation has taken place.
Thus, the only way to correctly consider synthetic edges is for the compiler
to know exactly which directives & pipes are used in a template during
'resolve'. There are two ways to achieve this:
1) refactor `TemplateDefinitionBuilder` to do its work in two phases, with
directive matching occurring as a separate step which can be performed
earlier.
2) use the `R3TargetBinder` in the 'resolve' phase to independently bind the
template and get information about used directives.
Option 1 is ideal, but option 2 is currently used for practical reasons. The
cost of binding the template can be shared with template-typechecking.
PR Close#29040
In the @Component decorator, the 'host' field is an object which represents
host bindings. The type of this field is complex, but is generally of the
form {[key: string]: string}. Several different kinds of bindings can be
specified, depending on the structure of the key.
For example:
```
@Component({
host: {'[prop]': 'someExpr'}
})
```
will bind an expression 'someExpr' to the property 'prop'. This is known to
be a property binding because of the square brackets in the binding key.
If the binding key is a plain string (no brackets or parentheses), then it
is known as an attribute binding. In this case, the right-hand side is not
interpreted as an expression, but is instead a constant string.
There is no actual requirement that at build time, these constant strings
are known to the compiler, but this was previously enforced as a side effect
of requiring the binding expressions for property and event bindings to be
statically known (as they need to be parsed). This commit breaks that
relationship and allows the attribute bindings to be dynamic. In the case
that they are dynamic, the references to the dynamic values are reflected
into the Ivy instructions for attribute bindings.
PR Close#29033
DynamicValues are generated whenever a partially evaluated expression is
unable to be resolved statically. They contain a reference to the ts.Node
which wasn't resolvable.
They can also be nested. For example, the expression 'a + b' is resolvable
only if 'a' and 'b' are themselves resolvable. If either 'a' or 'b' resolve
to a DynamicValue, the whole expression must also resolve to a DynamicValue.
Previously, if 'a' resolved to a DynamicValue, the entire expression might
have been resolved to the same DynamicValue. This correctly indicated that
the expression wasn't resolvable, but didn't return a reference to the
shallow node that couldn't be resolved (the expression 'a + b'), only a
reference to the deep node that couldn't be resolved ('a').
In certain situations, it's very useful to know the shallow unresolvable
node (for example, to use it verbatim in the output). To support this,
the partial evaluator is updated to always wrap DynamicValue to point to
each unresolvable expression as it's processed, ensuring the receiver can
determine exactly which expression node failed to resolve.

which meant also using default VSCode formatting settings for files
where this was not desirable - for example HTML files (such as

This was problematic for the following reasons:
- Unlike with JS/TS files, the formatting of other file types is not
checked/enforced on CI.
- Formatting is subject to default VSCode settings and everyone's local
VSCode settings overrides.
- Especially for docs examples files, changing the layout might require
updating the wording in corresponding guides (e.g. when referring to

If we decide that we do want to lint those other file types as well
(which sounds like a good idea), we should do it in a way that ensures

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
current state of the system.
Patching the array with extra property does change the array's hidden class' but it does not
change the cost of access, therefore this patching should not have significant if any impact in
`ngDevMode` mode. (see: https://jsperf.com/array-vs-monkey-patch-array)

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 commit splits apart selector_scope.ts in ngtsc and extracts the logic
into two separate classes, the LocalModuleScopeRegistry and the
DtsModuleScopeResolver. The logic is cleaned up significantly and new tests
are added to verify behavior.
LocalModuleScopeRegistry implements the NgModule semantics for compilation
scopes, and handles NgModules declared in the current compilation unit.
DtsModuleScopeResolver implements simpler logic for export scopes and
handles NgModules declared in .d.ts files.
This is done in preparation for the addition of re-export logic to solve
StrictDeps issues.

During build time we remap particular property bindings, because their names don't match their attribute equivalents (e.g. the property for the `for` attribute is called `htmlFor`).

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.

PR Close#28832
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.

Prior to this change we used current injector implementation for module injector, which was causing problems and produces circular dependencies in case the same token is referenced (with @SkipSelf flag) in the `deps` array. The origin of the problem was that once `directiveInject` implementation becomes active, it was used for module injector as well, thus searching deps in Component/Directive DI scope. This fix sets `injectInjectorOnly` implementation for module injector to resolve the problem.

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
match the behavior of "ngtsc" then (unless explicitly opted-out).
As mentioned before, internally at Google symbol re-exports need to
be still enabled, so the `ng_module` Bazel rule will enable the symbol
re-exports by default when running within Blaze.

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.

Previously the call to `extractSourceMap()` would only work if the

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[])`.

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.

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.

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.

Previously, `ng-packages-installer` would replace the version ranges for
all dependencies that were peer dependencies of an Angular package with

This commit reduces non-determinism in CI jobs using the locally built
Angular packages by always using pinned versions of dependencies for
Angular package peer dependencies if possible.

`ng-packages-installer` can be used to replace Angular packages with

Previously, in order to achieve this, `yarn install` was called with the
`--no-lockfile` option, which resulted in installing the latest versions
of all dependencies (including transitive ones) permitted by the
corresponding version ranges in `package.json` files. As a result, newly
released versions would be picked, resulting in unexpected,
non-deterministic breakages in CI.
This commit calls `yarn install` with the `--pure-lockfile` option
instead. As a result, only the Angular packages (for which the locally
built ones are used) and their peer dependencies are unpinned; the
pinned versions from `yarn.lock` are used for all other (direct and
transitive) dependencies.

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.

Previously all Bazel repositories were cached on CircleCI
because the `experimental_repository_cache` flag has been
specified and the given repository cache directory has been
included in the CircleCI cache storage.
The directory is currently still included in the CircleCI
cache storage, but the `--repository_cache` flag is no longer
specified, and the cache directory is basically empty all the
time. The flag seems to have been removed accidentally within
SHA c8b70ae8e4.
We should specifiy this flag on the CI again, so that Bazel
doesn't need to install the Bazel managed node modules
all the time. This would slow down analysis phase on CI; and also
makes us dependent on the Yarn/NPM registry which often times out
if we fetch a lot of dependencies.
Also in order to make sure that cached Bazel repositories are
also most of the time in sync with what's currently defined in
the workspace, we need to update the cache key.

Currently when someone serves the "person_management" playground

This happens because the example is outdated and the input elements

Currently whenever someone creates a pull request, the NPM dependencies
are downloaded and installed. This is problematic because we have a lot
NPM dependencies with potentially large files that would need to be
downloaded (e.g. the Bazel binaries).
The caches are currently not being restored because we added the
`{Branch}` variable to the CircleCI cache key. Since every PR has a different
branch name (e.g. `devversion/refs/heads/my-banch`), the cache keys would
never match an existing cache key, and the PR would start fresh by
downloading everything.
We can safely remove the `{Branch}` variable from the cache key because
it does not provide any value since the cached files are based on the state
of the `yarn.lock` file and not based on the current branch name. This reduces
our dependency on the slow and sometimes **flaky** Yarn registry. We should
try to depend as few as possible on external services (e.g. see how Saucelabs
flakiness can cause trouble for the caretaker; same applies to flaky Yarn installs)

destroy the view (again). We also add a check to `destroyLView` to skip

PR Close#28412
By its nature, Ivy alters the import graph of a TS program, adding imports
where template dependencies exist. For example, if ComponentA uses PipeB
in its template, Ivy will insert an import of PipeB into the file in which
ComponentA is declared.
Any insertion of an import into a program has the potential to introduce a
cycle into the import graph. If for some reason the file in which PipeB is
declared imports the file in which ComponentA is declared (maybe it makes
use of a service or utility function that happens to be in the same file as
ComponentA) then this could create an import cycle. This turns out to
happen quite regularly in larger Angular codebases.
TypeScript and the Ivy runtime have no issues with such cycles. However,
other tools are not so accepting. In particular the Closure Compiler is
very anti-cycle.
To mitigate this problem, it's necessary to detect when the insertion of
an import would create a cycle. ngtsc can then use a different strategy,
known as "remote scoping", instead of directly writing a reference from
one component to another. Under remote scoping, a function
'setComponentScope' is called after the declaration of the component's
module, which does not require the addition of new imports.

ngcc's reflection host needs to be able to determine all members of a
class, which it does by using the `ts.Symbol` from TypeScript's
TypeChecker. Such Symbol however may represent multiple class members
in the case of accessors; an equally named getter/setter accessor pair
is combined into a single `ts.Symbol`.
This commit introduces logic to recognize such accessors in order for
both the getter and setter to be considered as class member, similar to
ngtsc's behavior when operating on original TypeScript code.
One difference wrt the TypeScript host is that ngcc cannot see to which
accessor originally had any decorators applied to them, as decorators
are applied to the property descriptor in general, not a specific accessor.
If an accessor has both a setter and getter, any decorators are only
attached to the setter member.
PR Close#28357
Prior to this change, accessor functions for getters and setters would
not be considered as class member, as their declaration is vastly
different from ES2015 syntax.

downleveled syntax for accessors, allowing for them to be considered as
class member once again.

There are cases where we should check an element injector but don't go
into the associated module injector if a token is not found. In both the
view engine and ngIvy this is acheived by passing the

Before this fix the view engine and ngIvy were using different objects to
represent `NOT_FOUND_CHECK_ONLY_ELEMENT_INJECTOR`. This was causing problems
as ngUpgrade is using `NOT_FOUND_CHECK_ONLY_ELEMENT_INJECTOR` const in its

- TNodes are not really needed to fully support projectable nodes so we were
creating objects and updating existing data structures for nothing.
This commit changes the approach so we don't create "fake" TNodes for projectable
nodes but instead we process projectable nodes directly in the projection instruction.
As a result we've got less code, less object allocation and - as a bonus - we fix few
bugs where TView / TNode data structures were corrupted when using projectable nodes.

This commit changes the partial evaluation mechanism to propagate
DynamicValue errors internally during evaluation, and not to "poison"
entire data structures when a single value is dynamic. For example,
previously if any entry in an array was dynamic, evaluating the entire
array would return DynamicValue. Now, the array is returned with only
the specific dynamic entry as DynamicValue.
Instances of DynamicValue also report the node that was determined to
be dynamic, as well as a potential reason for the dynamic-ness. These
can be nested, so an expression `a + b` may have a DynamicValue that
indicates the 'a' term was DynamicValue, which will itself contain a
reason for the dynamic-ness.
This work was undertaken for the implementation of listLazyRoutes(),
which needs to partially evaluate provider arrays, parts of which are
dynamic and parts of which contain useful information.

Previous to this change, the isStylingContext() function was improperly
returning true for LContainers because it used the presence of an array
at index 2 to determine whether it was a styling context. Unfortunately,
LContainers also contain arrays at index 2, so this would return a false
positive. This led to other errors down the line because we would treat
nodes with containers as if they already had styling contexts (even if
they did not), so the proper initialization logic for styling contexts
was not run.
This commit fixes the isStylingContext() function to use LCONTAINER_LENGTH
as a marker rather than the presence of an array, which in turn fixes
host bindings to styles on nodes with containers.

There were two issues with multiple ICU expressions in the same i18n block:
- the regexp that was used to parse the text wasn't able to handle multiple ICU expressions, I've replaced it with parsing the text and searching for brackets (which is what we ended up doing in the end anyway)
- we allocate node indexes for nodes generated by the ICU expressions which increases the expando value, but we would create the nodes for those cases during the update phase. In the mean time we would create some nodes during the creation phase (comment nodes for ICU expressions, text nodes, ...) with an auto increment index. This means that any node created after an ICU expression would get the following index value, but the ICU case nodes expected to use the same index as well... There was a mismatch between the auto generated index, and the expected index which was causing problems when we needed to select those nodes for updates later on. To fix it, I've added the expected node index to the list of mutate codes that we generate, and we do not use an auto increment value anymore.

With the update to TypeScript 3.2.x, a big issue seems to have appeared for downstream Bazel users. If the downstream user still uses a lower TypeScript version, normal Bazel targets using the `ng_module` rule are still compiled with the correct/old TypeScript version (assuming they set the `node_modules` attribute properly).
But, if they build the previous Bazel targets by specifying them within a `ng_package` rule, the TypeScript version from the Angular `workspace` is being used for the replayed ESM5 compilation. This is because we resolve the replay compiler to `ngc_wrapped` or `tsc_wrapped` Bazel executables which are defined as part of the `angular` workspace. This means that the compilers are different if the downstream user uses `ngc-wrapped` from the `@npm` repository because the replayed compilation would use the compiler with `@ngdeps//typescript`.
In order to fix this, we should just use the compiler that is defined in the `@angular//BUILD.bazel` file. This target by defaults to the "@npm" workspace which is working for downstream users. This is similar to how it is handled for `tsc-wrapped`. `tsc-wrapped` works as expected for downstream users.
**Note**: This is not the ideal solution because ideally we would
completely respect the `compiler` option from the base `ng_module`, but
this is not possible in a hermetic way, unless we somehow accept the
`compiler` as an attribute that builds all transitive deps. This is
something we should explore in the future. For now, we just fix this in
a reasonable way that is also used for `tsc_wrapped` from the TypeScript
rules.

When an @NgModule decorator executes, the module is added to a queue in
render3/jit/module.ts. Reading an ngComponentDef property causes this queue
to be flushed, ensuring that the component gets the correct module scope
applied.
In before_each.ts, a global beforeEach is added to all Angular tests which
calls TestBed.resetTestingModule() prior to running each test. This in turn
clears the module compilation queue (which is correct behavior, as modules
declared within the test should not leak outside of it via the queue).
So far this is okay. But before the first test runs, the module compilation
queue is full of modules declared in global scope. No definitions have been
read, so no flushes of the queue have been triggered. The global beforeEach
triggers a reset of the queue, aborting all of the in-progress global
compilation, breaking those classes when they're later used in tests.
This commit adds logic to TestBedRender3 to respect the state of the module
queue before the TestBed is first initialized or reset. The queue is flushed
prior to such an operation to ensure global compilation is allowed to finish
properly.

An @NgModule with invalid provider declarations produces errors under
normal circumstances. However, within the TestBed two small issues with
provider overrides interfered with the correct production of these errors:
1. a 'null' provider object caused a premature crash when the TestBed
attempted to check for a 'provide' property on it with hasOwnProperty().
2. the array of providers would have an empty override array appended to it
for each input provider, which would pollute the error messages produced
down the line.

Libraries that create components dynamically using component factories,
such as `@angular/upgrade` need to pass blocks of projected content
through to the `ComponentFactory.create()` method. These blocks
are extracted from the content by matching CSS selectors defined in
`<ng-content select="..">` tags found in the component's template.
The Angular compiler collects these CSS selectors when compiling a component's
template, and exposes them via the `ComponentFactory.ngContentSelectors`
property.
This change ensures that this property is filled correctly when the
component factory is created by compiling a component with the Ivy engine.

Previous to this change, there was a lot of noise when
trying to find tests in FIND_PASSING_TESTS mode because
tests marked "onlyInIvy" were also listed as "already
passing". Since these tests are not "fixmes" that need
to be enabled, it is not useful to have them listed.
This commit removes "onlyInIvy" tests from consideration
when running in this manual mode. The tests should still
run on CI by default (since FIND_PASSING_TESTS mode will
be false).

exportAs in @Directive metadata supports multiple values, separated by
commas. Previously it was treated as a single value string.

Generated factory shims can import from @angular/core. However, we have
special logic in place to rewrite self-imports when generating code for
@angular/core.
This commit leverages the new standalone ImportRewriter interface to
properly rewrite imports in generated factory shims. Before this fix,
a generated factory file for core would look like:
```typescript
import * as i0 from './r3_symbols';
export var ApplicationModuleNgFactory = new ɵNgModuleFactory(...);
```
This is invalid, as ɵNgModuleFactory is just NgModuleFactory when imported
via r3_symbols.

Currently the ImportManager class handles various rewriting actions of
imports when compiling @angular/core. This is required as code compiled
within @angular/core cannot import from '@angular/core'. To work around
this, imports are rewritten to get core symbols from a particular file,
r3_symbols.ts.
In this refactoring, this rewriting logic is moved out of the ImportManager
and put behind an interface, ImportRewriter. There are three implementers
of the interface:
* NoopImportRewriter, used for compiling all non-core packages.
* R3SymbolsImportRewriter, used when ngtsc compiles @angular/core.
* NgccFlatImportRewriter, used when ngcc compiles @angular/core (special
logic is needed because ngcc has to rewrite imports in flat bundles
differently than in non-flat bundles).
This is a precursor to using this rewriting logic in other contexts besides
the ImportManager.

TestBed used to have its own implementation of the `transitiveScopesFor` function, customized for TestBed needs (to compile NgModules).

These tests validate the ability of the View Engine TestBed to consume
summary metadata, a mechanism which allows the TestBed to use
AOT-compiled components & directives in tests. It achieves this through
two operations which are independently obsolete in Ivy:
1. It injects CompileMetadataResolver, a View Engine specific compiler
internal class which extracts global analysis metadata from classes,
and uses it to construct summary metadata. This happens in a
beforeEach() block which calls createSummaries().
2. It uses TestBed.initTestEnvironment to pass summary metadata to the
TestBed itself. Any such metadata is ignored in Ivy.
Operation #1 makes it impossible to run these tests under Ivy, as the
CompileMetadataResolver is not available with an Ivy compiler.
Ivy itself does not rely on summary data, and the R3TestBed can depend
directly on AOT compiled components without it. Thus, the spirit of thes
tests is obsolete in an Ivy world.

A constructor function may have been "synthesized" by TypeScript during
JavaScript emit, in the case no user-defined constructor exists and e.g.
property initializers are used. Those initializers need to be emitted
into a constructor in JavaScript, so the TypeScript compiler generates a
synthetic constructor.
This commit adds identification of such constructors as ngcc needs to be
able to tell if a class did originally have a constructor in the
TypeScript source. When a class has a superclass, a synthesized
constructor must not be considered as a user-defined constructor as that
prevents a base factory call from being created by ngtsc, resulting in a
factory function that does not inject the dependencies of the superclass.
Hence, we identify a default synthesized super call in the constructor
body, according to the structure that TypeScript emits.

This commit adds sanitization for `elementProperty` and `elementAttribute` instructions used in `hostBindings` function, similar to what we already have in the `template` function. Main difference is the fact that for some attributes (like "href" and "src") we can't define which SecurityContext they belong to (URL vs RESOURCE_URL) in Compiler, since information in Directive selector may not be enough to calculate it. In order to resolve the problem, Compiler injects slightly different sanitization function which detects proper Security Context at runtime.

Previously, ngtsc would assume that a given directive/pipe being imported
from an external package was importable using the same name by which it
was declared. This isn't always true; sometimes a package will export a
directive under a different name. For example, Angular frequently prefixes
directive names with the 'ɵ' character to indicate that they're part of
the package's private API, and not for public consumption.
This commit introduces the TsReferenceResolver class which, given a
declaration to import and a module name to import it from, can determine
the exported name of the declared class within the module. This allows
ngtsc to pick the correct name by which to import the class instead of
making assumptions about how it was exported.
This resolver is used to select a correct symbol name when creating an
AbsoluteReference.

This commit adds tracking of modules, directives, and pipes which are made
visible to consumers through NgModules exported from the package entrypoint.
ngtsc will now produce a diagnostic if such classes are not themselves
exported via the entrypoint (as this is a requirement for downstream
consumers to use them with Ivy).
To accomplish this, a graph of references is created and populated via the
ReferencesRegistry. Symbols exported via the package entrypoint are compared
against the graph to determine if any publicly visible symbols are not
properly exported. Diagnostics are produced for each one which also show the
path by which they become visible.
This commit also introduces a diagnostic (instead of a hard compiler crash)
if an entrypoint file cannot be correctly determined.

directives to be exported.

Upcoming work to implement import resolution will change the dependencies
of some higher-level classes in ngtsc & ngcc. This necessitates changes in
how these classes are created and the lifecycle of the ts.Program in ngtsc
& ngcc.
To avoid complicating the implementation work with refactoring as a result
of the new dependencies, the refactoring is performed in this commit as a
separate prepatory step.
In ngtsc, the testing harness is modified to allow easier access to some
aspects of the ts.Program.
In ngcc, the main change is that the DecorationAnalyzer is created with the
ts.Program as a constructor parameter. This is not a lifecycle change, as
it was previously created with the ts.TypeChecker which is derived from the
ts.Program anyways. This change requires some reorganization in ngcc to
accommodate, especially in testing harnesses where DecorationAnalyzer is
created manually in a number of specs.

This refactoring moves code around between a few of the ngtsc subpackages,
with the goal of having a more logical package structure. Additional
interfaces are also introduced where they make sense.
The 'metadata' package formerly contained both the partial evaluator,
the TypeScriptReflectionHost as well as some other reflection functions,
and the Reference interface and various implementations. This package
was split into 3 parts.
The partial evaluator now has its own package 'partial_evaluator', and
exists behind an interface PartialEvaluator instead of a top-level
function. In the future this will be useful for reducing churn as the
partial evaluator becomes more complicated.
The TypeScriptReflectionHost and other miscellaneous functions have moved
into a new 'reflection' package. The former 'host' package which contained
the ReflectionHost interface and associated types was also merged into this
new 'reflection' package.
Finally, the Reference APIs were moved to the 'imports' package, which will
consolidate all import-related logic in ngtsc.

This commit fixes it by retrieving the compare URL from the original

I've previously verified that all the tests executed in legacy-unit-tests-local already under bazel.
Therefore the legacy-unit-tests-local job is strictly not necessary any more, but given how flaky legacy-unit-tests-saucelabs is,
it is good to have the -local job just so that we can quickly determine if any failure is a flake or legit issue

`R3TestBed` allows consumers to configure a "testing module", declare components, override various metadata, etc. To do this, it implements its own JIT compilation, where components/directives/modules have Ivy definition fields generated based on testing metadata. It results in tests interfering with each other. One test might override something in a component that another test tries to use normally, causing failures.
In order to resolve this problem, we store current components/directives/modules defs before applying overrides and re-compiling. Once the test is complete, we restore initial defs, so the next tests interact with "clean" components.

This folder contains configuration for the [CodeFresh](<https://codefresh.io/>) based CI checks for this repository.
## The build pipeline
CodeFresh uses a several pipeline for each repository. The `codefresh.yml` file defines pipeline [build steps](https://codefresh.io/docs/docs/configure-ci-cd-pipeline/introduction-to-codefresh-pipelines/) for this repository.
Run results can be seen in the GitHub checks interface and in the [public pipeline](https://g.codefresh.io/public/accounts/angular/pipelines/angular/angular/angular)
Although most configuration is done via `pipeline.yml`, some options are only available in the online [pipeline settings](https://g.codefresh.io/pipelines/angular/services?repoOwner=angular&repoName=angular&project=angular%2Fangular&context=github&serviceName=angular%2Fangular), which needs a login to access.
## Caretaker
CodeFresh status can be found at <http://status.codefresh.io/>.
Issues related to the CodeFresh setup should be escalated to the Tools Team via the current caretaker, followed by Alex Eagle and Filipe Silva.
## Rollout strategy
Currently it is only used for tests on Windows platforms, on the master branch, and without pushing user-facing reports. It's only possible to see current builds in the [public pipeline dashboard](https://g.codefresh.io/public/accounts/angular/pipelines/angular/angular/angular).
After a week or two of running like this, we should reassess how stable and reliable it is.

### Building with Bazel
Optionally, you can configure the Angular CLI to use [Bazel](https://docs.bazel.build) as the build tool. For more information, see [Building with Bazel](guide/bazel).
Users can opt in to share their Angular CLI usage data with [Google Analytics](https://support.google.com/analytics/answer/1008015?hl=en), using the [`ng analytics` CLI command](analytics).
The data is also shared with the Angular team, and used to improve the CLI.
The gathering of CLI analytics data is disabled by default, and must be enabled at the project level by individual users.
It cannot be enabled at the project level for all users.
Data gathered in this way can be viewed on the Google Analytics site, but is not automatically visible on your own organization's Analytics site.
As an administrator for an Angular development group, you can configure your instance of Angular CLI to be able to see analytics data for your own team's usage of the Angular CLI.
This configuration option is separate from and in addition to other usage analytics that your users may be sharing with Google.
## Enable access to CLI usage data
To configure access to your own users' CLI usage data, use the `ng config` command to add a key to your global [`angular.json` workspace configuration file](guide/workspace-config).
The key goes under `cli.analyticsSharing` at the top level of the file, outside the `projects` sections.
The value of the key is your organization's tracking ID, as assigned by Google Analytics.
This ID is a string that looks like `UA-123456-12`.
You can choose to use a descriptive string as the key value, or be assigned a random key when you run the CLI command.
For example, the following command adds a configuration key named "tracking".
<code-examplelanguage="sh"class="code-shell">
ng config --global cli.analyticsSharing.tracking UA-123456-12
</code-example>
To turn off this feature, run the following command:
<code-examplelanguage="sh"class="code-shell">
ng config --global --remove cli.analyticsSharing
</code-example>
## Per user tracking
You can add a custom user ID to the global configuration, in order to identify unique usage of commands and flags.
If that user enables CLI analytics for their own project, your analytics display tracks and labels their individual usage.
<code-examplelanguage="sh"class="code-shell">
ng config --global cli.analyticsSharing.user SOME_USER_NAME
</code-example>
To generate a new random user ID, run the following command:
