When ngcc creates an entry-point program, the `allowJs` option is enabled
in order to operate on the JavaScript source files of the entry-point.
A side-effect of this approach is that external modules that don't ship
declaration files will also have their JavaScript source files loaded
into the program, as the `allowJs` flag allows for them to be imported.
This may pose an issue in certain edge cases, where ngcc would inadvertently
operate on these external modules. This can introduce all sorts of undesirable
behavior and incompatibilities, e.g. the reflection host that is selected for
the entry-point's format could be incompatible with that of the external
module's JavaScript bundles.
To avoid these kinds of issues, module resolution that would resolve to
a JavaScript file located outside of the package will instead be rejected,
as if the file would not exist. This would have been the behavior when
`allowJs` is set to false, which is the case in typical Angular compilations.

Previously, event listeners for component output events attached on an
Angular custom element before inserting it into the DOM (i.e. before
instantiating the underlying component) didn't fire for events emitted
during initialization lifecycle hooks, such as `ngAfterContentInit`,
`ngAfterViewInit`, `ngOnChanges` (initial call) and `ngOnInit`.
The reason was that `NgElementImpl` [subscribed to events][1] _after_
calling [ngElementStrategy#connect()][2], which is where the
[initial change detection][3] takes place (running the initialization
lifecycle hooks).
This commit fixes this by:
1. Ensuring `ComponentNgElementStrategy#events` is defined and available
for subscribing to, even before instantiating the component.
2. Changing `NgElementImpl` to subscribe to `NgElementStrategy#events`
(if available) before calling `NgElementStrategy#connect()` (which
initializes the component instance) if available.
3. Falling back to the old behavior (subscribing to `events` after
calling `connect()` for strategies that do not initialize `events`
before their `connect()` is run).
NOTE:
By falling back to the old behavior when `NgElementStrategy#events` is
not initialized before calling `NgElementStrategy#connect()`, we avoid
breaking existing custom `NgElementStrategy` implementations (with
@remackgeek's [ElementZoneStrategy][4] being a commonly used example).

If [innerHTML] is used in a component and a Content-Security-Policy is set
that does not allow inline styles then Firefox and Chrome show the following
message:
> Content Security Policy: The page’s settings observed the loading of a
resource at self (“default-src”). A CSP report is being sent.
This message is caused because Angular is creating an inline style tag to
test for a browser bug that we use to decide what sanitization strategy to
use, which causes CSP violation errors if inline CSS is prohibited.
This test is no longer necessary, since the `DOMParser` is now safe to use
and the `style` based check is redundant.
In this fix, we default to using `DOMParser` if it is available and fall back
to `createHTMLDocument()` if needed. This is the approach used by DOMPurify
too.
The related unit tests in `html_sanitizer_spec.ts`, "should not allow
JavaScript execution when creating inert document" and "should not allow
JavaScript hidden in badly formed HTML to get through sanitization (Firefox
bug)", are left untouched to assert that the behavior hasn't changed in

`getExternalFiles()` is an API that could optionally be provided by a tsserver plugin
to notify the server of any additional files that should belong to a particular project.
This API was removed in https://github.com/angular/angular/pull/34260 mainly
due to performance reasons.
However, with the introduction of "solution-style" tsconfig in typescript 3.9,
the Angular extension could no longer reliably detect the owning Project solely

In version 10.0.0-next.8, we introduced absolute URL support for

As of v10, the `undecorated-classes-with-decorated-fields` migration
generally deals with undecorated classes using Angular features. We
intended to run this migation as part of v10 again as undecorated
classes with Angular features are no longer supported in planned v11.
The migration currently behaves incorrectly in some cases where an
`@Injectable` or `@Pipe` decorated classes uses the `ngOnDestroy`
lifecycle hook. We incorrectly add a TODO for those classes. This
commit fixes that.
Additionally, this change makes the migration more robust to
not migrate a class if it inherits from a component, pipe
injectable or non-abstract directive. We previously did not
need this as the undecorated-classes-with-di migration ran
before, but this is no longer the case.
Last, this commit fixes an issue where multiple TODO's could be
added. This happens when multiple Angular CLI build targets have
an overlap in source files. Multiple programs then capture the
same source file, causing the migration to detect an undecorated
class multiple times (i.e. adding a TODO twice).

This commit introduces a dedicated `DynamicValue` kind to indicate that a value
cannot be evaluated statically as the function body is not just a single return
statement. This allows more accurate reporting of why a function call failed

and have a tailor-made diagnostic message.

During AOT compilation, the value of some expressions need to be known at
compile time. The compiler has the ability to statically evaluate expressions
the best it can, but there can be occurrences when an expression cannot be
evaluated statically. For instance, the evaluation could depend on a dynamic
value or syntax is used that the compiler does not understand. Alternatively,
it is possible that an expression could be statically evaluated but the
resulting value would be of an incorrect type.
In these situations, it would be helpful if the compiler could explain why it
is unable to evaluate an expression. To this extend, the static interpreter
in Ivy keeps track of a trail of `DynamicValue`s which follow the path of nodes
that were considered all the way to the node that causes an expression to be
considered dynamic. Up until this commit, this rich trail of information was
not surfaced to a developer so the compiler was of little help to explain
why static evaluation failed, resulting in situations that are hard to debug
and resolve.
This commit adds much more insight to the diagnostic that is produced for static
evaluation errors. For dynamic values, the trail of `DynamicValue` instances
is presented to the user in a meaningful way. If a value is available but not
of the correct type, the type of the resolved value is shown.

Commit 4213e8d5 introduced shim reference tagging into the compiler, and
changed how the `TypeCheckProgramHost` worked under the hood during the
creation of a template type-checking program. This work enabled a more
incremental flow for template type-checking, but unintentionally introduced
several regressions in performance, caused by poor incrementality during
`ts.Program` creation.
1. The `TypeCheckProgramHost` was made to rely on the `ts.CompilerHost` to
retrieve instances of `ts.SourceFile`s from the original program. If the
host does not return the original instance of such files, but instead
creates new instances, this has two negative effects: it incurs
additional parsing time, and it interferes with TypeScript's ability to
reuse information about such files.
2. During the incremental creation of a `ts.Program`, TypeScript compares
the `referencedFiles` of `ts.SourceFile` instances from the old program
with those in the new program. If these arrays differ, TypeScript cannot
fully reuse the old program. The implementation of reference tagging
introduced in 4213e8d5 restores the original `referencedFiles` array
after a `ts.Program` is created, which means that future incremental
operations involving that program will always fail this comparison,
effectively limiting the incrementality TypeScript can achieve.
Problem 1 exacerbates problem 2: if a new `ts.SourceFile` is created by the
host after shim generation has been disabled, it will have an untagged
`referencedFiles` array even if the original file's `referencedFiles` was
not restored, triggering problem 2 when creating the template type-checking
program.
To fix these issues, `referencedFiles` arrays are now restored on the old
`ts.Program` prior to the creation of a new incremental program. This allows
TypeScript to get the most out of reusing the old program's data.
Additionally, the `TypeCheckProgramHost` now uses the original `ts.Program`
to retrieve original instances of `ts.SourceFile`s where possible,
preventing issues when a host would otherwise return fresh instances.
Together, these fixes ensure that program reuse is as incremental as
possible, and tests have been added to verify this for certain scenarios.
An optimization was further added to prevent the creation of a type-checking
`ts.Program` in the first place if no type-checking is necessary.

Previously the `ProgramBasedEntryPointFinder` was parsing all the
entry-points referenced by the program for dependencies even if all the
entry-points had been processed already.
Now this entry-point finder will re-use the `EntryPointManifest` to load
the entry-point dependencies when possible which avoids having to parse
them all again, on every invocation of ngcc.
Previously the `EntryPointManifest` was only used in the
`DirectoryWalkerEntryPointFinder`, which also contained the logic for
computing the contents of the manifest. This logic has been factored out
into an `EntryPointCollector` class. Both the `ProgramBasedEntryPointFinder`
and `DirectoryWalkerEntryPointFinder` now use the `EntryPointManifest` and
the `EntryPointCollector`.
The result of this change is that there is a small cost on the first run of
ngcc to compute and store the manifest - the processing takes 102% of the
processing time before this PR. But on subsequent runs there is a
significant benefit on subsequent runs - the processing takes around 50%
of the processing time before this PR.

Interestingly enough, our rollup bundle optimization pipeline
did not work properly before 1b827b058e5060963590628d4735e6ac83c6dfdd.
Unused declarations were not elided because build optimizer did not
consider the Angular packages as side-effect free. Build optimizer has
a hard-coded list of Angular packages that are considered side-effect
free. Though this one did not match in the old version of the rollup
bundle rule, as internal sources were resolved through their resolved
bazel-out paths. Hence build optimizer could not detect the known
Angular framework packages. Now though, since we leverage the
Bazel-idiomatic `@bazel/rollup` implementation, sources are resolved
through linked `node_modules`, and build optimizer is able to properly
detect files as side-effect free.

Refactors the `ng_rollup_bundle` rule to a macro that relies on
the `@bazel/rollup` package. This means that the rule no longer
deals with custom ESM5 flavour output, but rather only builds
prodmode ES2015 output. This matches the common build output
in Angular projects, and optimizations done in CLI where
ES2015 is the default optimization input.
The motiviation for this change is:
* Not duplicating rollup Bazel rules. Instead leveraging the official
rollup rule.
* Not dealing with a third TS output flavor in Bazel.The ESM5 flavour has the
potential of slowing down local development (as it requires compilation replaying)
* Updating the rule to be aligned with current CLI optimizations.
This also _fixes_ a bug that surfaced in the old rollup bundle rule.
Code that is unused, is not removed properly. The new rule fixes this by
setting the `toplevel` flag. This instructs terser to remove unused
definitions at top-level. This matches the optimization applied in CLI
projects. Notably the CLI doesn't need this flag, as code is always
wrapped by Webpack. Hence, the unused code eliding runs by default.
