index in `TView`. This is incorrect, since if ICU is in `ngFor` it will
cause issues in some circumstances. This refactoring properly moves the

This commit fixes a bug when `useAbsoluteUrl` is set to true and
`ServerPlatformLocation` infers the base url from the supplied
`url`. User should explicitly set the `baseUrl` when they turn on
`useAbsoluteUrl`.
Breaking change:
If you use `useAbsoluteUrl` to setup `platform-server`, you now need to
also specify `baseUrl`.
We are intentionally making this a breaking change in a minor release,
because if `useAbsoluteUrl` is set to `true` then the behavior of the
application could be unpredictable, resulting in issues that are hard to
discover but could be affecting production environments.

This commit adds the basic building blocks for linking partial declarations.
In particular it provides a generic `FileLinker` class that delegates to
a set of (not yet implemented) `PartialLinker` classes.
The Babel plugin makes use of this `FileLinker` providing concrete classes
for `AstHost` and `AstFactory` that work with Babel AST. It can be created
with the following code:
```ts
const plugin = createEs2015LinkerPlugin({ /* options */ });

Use the bypass-specific Trusted Types policy for automatically upgrade
any values from custom sanitizers or the bypassSecurityTrust functions
to a Trusted Type. Update tests to reflect the new behavior.
PR Close#39218
When an application uses a custom sanitizer or one of the
bypassSecurityTrust functions, Angular has no way of knowing whether
they are implemented in a secure way. (It doesn't even know if they're
introduced by the application or by a shady third-party dependency.)
Thus using Angular's main Trusted Types policy to bless values coming
from these two sources would undermine the security that Trusted Types
brings.
Instead, introduce a Trusted Types policy called angular#unsafe-bypass
specifically for blessing values from these sources. This allows an
application to enforce Trusted Types even if their application uses a
custom sanitizer or the bypassSecurityTrust functions, knowing that
compromises to either of these two sources may lead to arbitrary script
execution. In the future Angular will provide a way to implement
custom sanitizers in a manner that makes better use of Trusted Types.

Sanitizers in Angular currently return strings, which will then
eventually make their way down to the DOM, e.g. as the value of an
attribute or property. This may cause a Trusted Types violation. As a
step towards fixing that, make it possible to return Trusted Types from
the SanitizerFn interface, which represents the internal sanitization
pipeline. DOM renderer interfaces are also updated to reflect the fact
that setAttribute and setAttributeNS must be able to accept Trusted
Types.

The JIT compiler uses the Function constructor to compile arbitrary
strings into executable code at runtime, which causes Trusted Types
violations. To address this, JitEvaluator is instead made to use the
Trusted Types compatible Function constructor introduced by Angular's
Trusted Types policy for JIT.
PR Close#39210
Introduce a Trusted Types policy for use by Angular's JIT compiler named
angular#unsafe-jit. As the compiler turns arbitrary untrusted strings
into executable code at runtime, using Angular's main Trusted Types
policy does not seem appropriate, unless it can be ensured that the
provided strings are indeed trusted. Until then, this JIT policy can be
allowed by applications that rely on the JIT compiler but want to
enforce Trusted Types, knowing that a compromise of the JIT compiler can
lead to arbitrary script execution. In particular, this is required for
enabling Trusted Types in Angular unit tests, since they make use of the
JIT compiler.
Also export the internal Trusted Types definitions from the core package
so that they can be used in the compiler package.

When an input name is part of the directive selector, it would be good to return the directive as well
when performing 'go to definition' or 'go to type definition'. As an example, this would allow
'go to type definition' for ngIf to take the user to the NgIf directive.
'Go to type definition' would otherwise return no results because the
input is a generic type. This would also be the case for all primitive
input types.

Angular treats constant values of attributes and properties in templates
as secure. This means that these values are not sanitized, and are
instead passed directly to the corresponding setAttribute or setProperty
function. In cases where the given attribute or property is
security-sensitive, this causes a Trusted Types violation.
To address this, functions for promoting constant strings to each of the
three Trusted Types are introduced to Angular's private codegen API. The
compiler is updated to wrap constant strings with calls to these
functions as appropriate when constructing the `consts` array. This is
only done for security-sensitive attributes and properties, as
classified by Angular's dom_security_schema.

The @types/trusted-types type definitions are currently imported in
types.d.ts, which causes them to eventually be imported in core.d.ts.
This forces anyone compiling against @angular/core to provide the
@types/trusted-types package in their compilation unit, which we don't
want.
To address this, get rid of the @types/trusted-types and instead import
a minimal version of the Trusted Types type definitions directly into
Angular's codebase.

definitions.

Previously, inline exports of the form `exports.foo = <implementation>;` were
being interpreted (by the ngtsc `PartialInterpeter`) as `Reference` objects.
This is not what is desired since it prevents the value of the export
from being unpacked, such as when analyzing `NgModule` declarations:
```
exports.directives = [Directive1, Directive2];
@NgImport({declarations: [exports.directives]})
class AppModule {}
```
In this example the interpreter would think that `exports.directives`
was a reference rather than an array that needs to be unpacked.

Some inline declarations are of the form:
```
exports.<name> = <implementation>;
```
In this case the declaration `node` is `exports.<name>`.
When interpreting such inline declarations we actually want

the declaration `node`.
This commit adds `implementation?: ts.Expression` to the
`InlineDeclaration` type and updates the interpreter to visit
these expressions as described above.

template type checker.

As of Angular v4, four of the options for
`ExtraOptions#initialNavigation` have been deprecated. We intend

- `enabledBlocking`: same as enabled
BREAKING CHANGE:
* The `initialNavigation` property for the options in
`RouterModule.forRoot` no longer supports `legacy_disabled`,
`legacy_enabled`, `true`, or `false` as valid values.
`legacy_enabled` (the old default) is instead `enabledNonBlocking`
* `enabled` is deprecated as a valid value for the
`RouterModule.forRoot` `initialNavigation` option. `enabledBlocking`

When ngcc is configured to run with the `--use-program-dependencies`
flag, as is the case in the CLI's asynchronous processing, it will scan
all source files in the program, starting from the program's root files
as configured in the tsconfig. Each individual root file could
potentially rescan files that had already been scanned for an earlier
root file, causing a severe performance penalty if the number of root
files is large. This would be the case if glob patterns are used in the
"include" specification of a tsconfig file.
This commit avoids the performance penalty by keeping track of the files
that have been scanned across all root files, such that no source file
is scanned multiple times.

Address a Trusted Types violation that occurs in createNamedArrayType
during development mode. Instead of passing strings directly to "new
Function", use the Trusted Types compatible function constructor exposed
by the Trusted Types policy.
PR Close#39209
Chrome currently does not support passing TrustedScript to the Function
constructor, and instead fails with a Trusted Types violation when
called. As the Function constructor is used in a handful of places
within Angular, such as in the JIT compiler and named_array_type, the
workaround proposed on the following page is implemented:
https://github.com/w3c/webappsec-trusted-types/wiki/Trusted-Types-for-function-constructor
To be precise, it constructs a string representing an anonymous function
in a way that is equivalent to what the Function constructor does,
promotes it to a TrustedScript and then calls eval.
To facilitate backwards compatibility, new Function is used directly in
environments that do not support Trusted Types.
