In ViewEngine injecting a Renderer2 returns a renderer that is specific to the particular component, however in Ivy we inject the renderer for the parent view instead. This causes it to set incorrect `ngcontent` attributes when creating elements through the renderer.
The issue comes from the fact that the `Renderer2` is created according to the current `LView`, but because DI happens before we've entered the `LView` of the component that's injecting the renderer, we end up with one that's one level up. We work around the issue by finding the `LView` that corresponds to the `previousOrParentTNode` inside of the parent view and associating the `Renderer2` with it.

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 View engine it was possible to declare multiple projection
definitions and to programmatically project nodes into the slots.
e.g.
```html

<ng-content></ng-content>
```
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).
It basically ensures that Ivy fully matches the View Engine behavior
except of a very small edge case that has already been discussed

fix(@schematics/angular): TypeScript related migrations should cater for BOM
In the CLI `UpdateRecorder` methods such as `insertLeft`, `remove` etc.. accepts positions which are not offset by a BOM. This is because when a file has a BOM a different recorder will be used https://github.com/angular/angular-cli/blob/master/packages/angular_devkit/schematics/src/tree/recorder.ts#L72 which caters for an addition offset/delta.
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.

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 commit makes the static flag on @ViewChild and @ContentChild required.
BREAKING CHANGE:
In Angular version 8, it's required that all @ViewChild and @ContentChild
queries have a 'static' flag specifying whether the query is 'static' or
'dynamic'. The compiler previously sorted queries automatically, but in
8.0 developers are required to explicitly specify which behavior is wanted.
This is a temporary requirement as part of a migration; see

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.

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.

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.

- Leaves behind one test for in-template javascript that is not supported syntax yet
PR Close#30406
Moves over the tests from `pipe_spec` into `acceptance`. Note that the two `WrappedValue` tests haven't been moved over, because impure pipes always throw "changed after checked" errors in `TestBed`. This seems to be consistent with ViewEngine.

Now that the dependent files and compilation scopes are being tracked in
the incremental state, we can skip analysing and emitting source files if
none of their dependent files have changed since the last compile.
The computation of what files (and their dependencies) are unchanged is
computed during reconciliation.
This commit also removes the previous emission skipping logic, since this
approach covers those cases already.
PR Close#30238
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
current compilation analysis was skipped.
PR Close#30238
As part of incremental compilation performance improvements, we need
to track the dependencies of files due to expressions being evaluated by
the `PartialEvaluator`.
The `PartialEvaluator` now accepts a `DependencyTracker` object, which is
used to track which files are visited when evaluating an expression.
The interpreter computes this `originatingFile` and stores it in the evaluation
`Context` so it can pass this to the `DependencyTracker.
The `IncrementalState` object implements this interface, which allows it to be
passed to the `PartialEvaluator` and so capture the file dependencies.

Moves most of the tests in `output_spec` into `acceptance`. Note that one test is left in `render3`, because it's testing mixing in custom logic with instructions which we can't replicate using `TestBed`.
PR Close#30372
Moves all manual `render3` content projection tests that use
the `ɵɵelementProperty` to acceptance tests. Additionally a
few other content projection tests were moved over to
acceptance. Eventually we'll be able to move all remaining

After this PR is merged, maintainers no longer need to update .bazelrc
file, toolchain and platform related flags for RBE builds and tests
(unless there is a breaking change in Bazel related to those flags).
Maintainers just need to update the pin of @bazel-toolchains repo
regularly in the packages/bazel/package.bzl file according to
https://releases.bazel.build/bazel-toolchains.html to include the
latest checked-in toolchain configs. If rbe_autoconfig() cannot find
appropriate toolchain configs for the version of Bazel in the version of
@bazel_toolchains repo that is currently used by this project, it will pull
down the container and generate the configs on the fly as the beginning
of the build/test.

Currently we always just set the timing to `false` if we aren't
able to analyze a given call expression or new expression. e.g.
```ts
ngOnInit() {
thirdPartyCallSync(() => this.query.doSomething())
}
```
In that case the `thirdPartyCallSync` function comes from the `node_modules`
and is only defined through types while there is no code for the
actual function logic that can be analyzed. This makes it impossible
to tell whether the given call expression actually causes the specified
arrow function to be executed synchronously or not. In order to be able
to make this better, we now peek into the passed arrow function and
check for a synchronous query usage. If so, we set the query timing to
static and mark it as ambiguous. This ensures that the usage strategy is
less "magical" and more correct with third-party code.
Additionally since functions like `setTimeout` are not analyzable but known
to be asynchronous, there is a hard-coded list of known functions which
shouldn't be marked as ambiguous.

Even though we don't run the size-tracking test on CI
right now, we update the golden size map as part of
the size-tracking tool update. The size-map difference
should generally be kept up-to-date to be able to
determine which PRs contribute size to a given file.
PR Close#30257
Based on discussion that happened on the PR that introduced
the size-tracking tool, we want to have another threshold for
the raw byte difference. This allows us to better control for
which changes the size-tracking tool should report a difference.

PR Close#30321
Currently the static-query migration ignores queries declared on getters
or setters as these are not part of a `PropertyDeclaration`. We need to
handle these queries in order to cover all queries within a given project.
The usage strategy is not able to detect timing for queries on accessors,
so we add a TODO and print a message. The template strategy is able
to detect the proper timing for such queries because it's not dependent
on detecting the usage of the query.

We have an issue where we would like to be able to test perf counter metrics in acceptance tests, but we are unable to do so, because it will break when those same tests are run with ViewEngine. This PR adds a testing utility to `onlyInIvy` that allows for testing of performance counters, and even gives readable errors for what value on `ngDevMode` is incorrect. Has typings for decent autocompletion as well.

This is the final patch to migrate the Angular styling code to have a
smaller instruction set in preparation for the runtime refactor. All
styling-related instructions now work both in template and hostBindings
functions and do not use `element` as a prefix for their names:
BEFORE:
elementStyling()
elementStyleProp()
elementClassProp()
elementStyleMap()
elementClassMap()
elementStylingApply()
AFTER:
styling()
styleProp()
classProp()
styleMap()
classMap()
stylingApply()
PR Close#30318
This patch removes all host-specific styling instructions in favor of
using element-level instructions instead. Because of the previous
patches that made sure `select(n)` worked between styling calls, all
host level instructions are not needed anymore. This patch changes each
of those instruction calls to use any of the `elementStyling*`,
`elementStyle*` and `elementClass*` styling instructions instead.
PR Close#30336
The static-query template strategy leverages the AOT compiler
in order to determine the query timing. Unfortunately the AOT
compiler has open bugs that can cause unexpected failures which
make the template strategy unusable in rare cases. These rare
exceptions need to be handled gracefully in order to avoid confusion
and to provide a more smooth migration.
Additionally migration strategy setup failures are now reported with
stack traces as the `ng update` command does not print stack traces.
This makes it easier to reproduce and report migration issues.
PR Close#30269
In an Angular CLI project scenario where projects only reference
top-level source-files through the `tsconfig` `files` option, we currently
do not migrate referenced source-files. This can be fixed checking all
referenced source-files which aren't coming from an external library.
This is similar to how `tslint` determines project source-files.

Currently when someone has a call expression within the `ngOnInit` call
and we try to peek into that function with respect to the current function
context, the schematic errors because a call expression argument is
undefined. This is valid because the target function declaration defines
that parameter with a default value. In order to fix this, we need to
respect parameter default values.

Fixes not being able to bind a `SafeStyle` as a camel cased style property (e.g. `[style.backgroundImage]="someSafeStyle"`). The issue was due to the fact that we only check the dash case property names to determine whether to sanitize a value.

572b54967c changed how the schematic
tests are executed. Tests no longer use the schematic collection
that is also used by the CLI `ng update` command and therefore
the migration collection could technically be invalid.
In order to ensure that the public migration collection is guaranteed
to work and to avoid duplication within two schematic collections, the
changes are partially reverted and only the disabled `injectable-pipe`
schematic has its own collection.
PR Close#30198
Currently we always prompt when the static-query migration runs. This is not
always needed because some applications do not even use `ViewChild` or
`ContentChild` queries and it just causes confusion if developers need to
decide on a migration strategy while there is nothing to migrate.
In order to avoid this confusion, we no longer prompt for a strategy
if there are no queries declared within the project.

This patch is one commit of many patches that will unify all styling instructions
across both template-level bindings and host-level bindings. This patch in particular
removes the `elementIndex` param because it is already set prior to each styling
instruction via the `select(n)` instruction.

Instead of launching a Node.js process that in turn spawns Bazel binary,
the Builder could now directly spawn the native binary. This makes the
bootup process slightly more efficient, and allows the Builder to
control spawn options. This works with both Bazel and iBazel.

Currently, in jit mode, `ngInjectableDef`, `ngDirectiveDef`, `ngPipeDef` and `ngModuleDef` use `ng://`,
which display them in the top domain in Chrome Dev Tools, whereas `ngComponentDef` uses `ng:///` which display components in a separate domain.
You can currently see:
```
AppModule
UserService
ng://

Prior to this patch, the `select(n)` instruction would only be generated
when property bindings are encountered which meant that styling-related
bindings were skipped. This patch ensures that all styling-related bindings
(i.e. class and style bindings) are always prepended with a `select()`
instruction prior to being generated in AOT.

This patch breaks up the existing `elementStylingMap` into
`elementClassMap` and `elementStyleMap` instructions. It also breaks
apart `hostStlyingMap` into `hostClassMap` and `hostStyleMap`
instructions. This change allows for better tree-shaking and reduces
the complexity of the styling algorithm code for `[style]` and `[class]`
bindings.
PR Close#30293
If an entry-point has a missing dependency then all the entry-points
that would have pointed to that dependency are also removed from
the dependency graph.
Previously we were still processing the dependencies of an entry-point
even if it had already been removed from the graph because it depended
upon a missing dependency that had previously been removed due to another
entry-point depending upon it.
This caused the dependency processing to crash rather than gracefully
logging and handling the missing invalid entry-point.
