Andrew Kushnir 6cff877f4f perf(core): make DI decorators tree-shakable when used for `useFactory` deps config (#40145)
This commit updates the logic that calculates `useFactory` function arguments to avoid relying on `instanceof`
checks (thus always retaining symbols) and relies on flags that DI decorators contain (as a monkey-patched property).

Another perf benefit is having less megamorphic reads while calculating args for the `useFactory` call: we used to
check whether a token has `ngMetadataName` property 4 times (in worst case), now we have just 1 megamorphic read in
all cases.

Closes #40143.

JoostK b48eabddb8 refactor(compiler-cli): include `template` source directly inside declaration object (#40383)
The `template` and `isInline` fields were previously stored in a nested
object, which was initially done to accommodate for additional template
information to support accurate source maps for external templates. In
the meantime the source mapping has been accomplished in a different
way, and I feel this flattened structure is simpler and smaller so is
preferable over the nested object. This change also makes the `isInline`
property optional with a default value of `false`.

Kristiyan Kostadinov 4f73820ad6 fix(core): memory leak if view container host view is destroyed while view ref is not (#40219)
When we attach a `ViewRef` to a `ViewContainerRef`, we save a reference to the container
onto the `ViewRef` so that we can remove it when the ref is destroyed. The problem is
that if the container's `hostView` is destroyed first, the `ViewRef` has no way of knowing
that it should stop referencing the container.

These changes remove the leak by not saving a reference at all. Instead, when a `ViewRef`
is destroyed, we clean it up through the `LContainer` directly. We don't need to worry
about the case where the container is destroyed before the view, because containers
automatically clean up all of their views upon destruction.

Fixes #38648.

Kristiyan Kostadinov 104546569e fix(compiler): incorrectly interpreting some HostBinding names (#40233)
Currently when analyzing the metadata of a directive, we bundle together the bindings from `host`
and the `HostBinding` and `HostListener` together. This can become a problem later on in the
compilation pipeline, because we try to evaluate the value of the binding, causing something like
`@HostBinding('class.foo') public true = 1;` to be treated the same as
`host: {'[class.foo]': 'true'}`.

While looking into the issue, I noticed another one that is closely related: we weren't treating
quoted property names correctly. E.g. `@HostBinding('class.foo') public "foo-bar" = 1;` was being
interpreted as `classProp('foo', ctx.foo - ctx.bar)` due to the same issue where property names
were being evaluated.

These changes resolve both of the issues by treating all `HostBinding` instance as if they're
reading the property from `this`. E.g. the `@HostBinding('class.foo') public true = 1;` from above
is now being treated as `host: {'[class.foo]': 'this.true'}` which further down the pipeline becomes
`classProp('foo', ctx.true)`. This doesn't have any payload size implications for existing code,
because we've always been prefixing implicit property reads with `ctx.`. If the property doesn't
have an identifier that can be read using dotted access, we convert it to a quoted one (e.g.
`classProp('foo', ctx['is-foo']))`.

Andrew Scott e43f7e26fe fix(router): apply redirects should match named outlets with empty path parents (#40029)
There are two parts to this commit:
1. Revert the changes from #38379. This change had an incomplete view of
how things worked and also diverged the implementations of
`applyRedirects` and `recognize` even more.
2. Apply the fixes from the `recognize` algorithm to ensure that named
outlets with empty path parents can be matched. This change also passes
all the tests that were added in #38379 with the added benefit of being
a more complete fix that stays in-line with the `recognize` algorithm.
This was made possible by using the same approach for `split` by
always creating segments for empty path matches (previously, this was
only done in `applyRedirects` if there was a `redirectTo` value). At the
end of the expansions, we need to squash all empty segments so that
serializing the final `UrlTree` returns the same result as before.

Kristiyan Kostadinov e4fbab9ec8 fix(core): error if detectChanges is called at the wrong time under specific circumstances (#40206)
Internally we store lifecycle hooks in the format `[index, hook, index, hook]` and when
iterating over them, we check one place ahead to figure out whether we've hit found
a hook or an index. The problem is that the loop is set up to iterate up to `hooks.length`
which means that we may go out of bounds on the last iteration, depending on where
we started. This appears to happen under a specific set of circumstances where a
directive calls `detectChanges` from an input setter while it has `ngOnChanges` and
`ngAfterViewInit` hooks.

These changes resolve the issue by only iterating up to `length - 1` which guarantees that
we can always look one place ahead.

This appears to have regressed some time in version 10.

JoostK e23fd1f382 refactor(compiler-cli): emit `forwardRef` invocation for forward type references (#40117)
The types of directives and pipes that are used in a component's
template may be emitted into the partial declaration wrapped inside a
closure, which is needed when the type is declared later in the module.
This poses a problem for JIT compilation of partial declarations, as
this closure is indistinguishable from a class reference itself. To mark
the forward reference function as such, this commit changes the partial
declaration codegen to emit a `forwardRef` invocation wrapped around
the closure, which ensures that the closure is properly tagged as a
forward reference. This allows the forward reference to be treated as
such during JIT compilation.

Misko Hevery 47d9b6d72d fix(core): fix possible XSS attack in development through SSR. (#40136)
Escape the content of the strings so that it can be safely inserted into a comment node.
The issue is that HTML does not specify any way to escape comment end text inside the comment.
`<!-- The way you close a comment is with "-->". -->`. Above the `"-->"` is meant to be text
not an end to the comment. This can be created programmatically through DOM APIs.

```
div.innerHTML = div.innerHTML
```
One would expect that the above code would be safe to do, but it turns out that because comment
text is not escaped, the comment may contain text which will prematurely close the comment
opening up the application for XSS attack. (In SSR we programmatically create comment nodes which
may contain such text and expect them to be safe.)
This function escapes the comment text by looking for the closing char sequence `-->` and replace
it with `-_-_>` where the `_` is a zero width space `\u200B`. The result is that if a comment
contains `-->` text it will render normally but it will not cause the HTML parser to close the
comment.

JoostK 1f73af77a7 refactor(compiler-cli): use `ngDevMode` guard for `setClassMetadata` call (#39987)
Prior to this change, the `setClassMetadata` call would be invoked
inside of an IIFE that was marked as pure. This allows the call to be
tree-shaken away in production builds, as the `setClassMetadata` call
is only present to make the original class metadata available to the
testing infrastructure. The pure marker is problematic, though, as the
`setClassMetadata` call does in fact have the side-effect of assigning
the metadata into class properties. This has worked under the assumption
that only build optimization tools perform tree-shaking, however modern
bundlers are also able to elide calls that have been marked pure so this
assumption does no longer hold. Instead, an `ngDevMode` guard is used
which still allows the call to be elided but only by tooling that is
configured to consider `ngDevMode` as constant `false` value.

JiaLiPassion 5e92d649f2 feat(core): add shouldCoalesceRunChangeDetection option to coalesce change detections in the same event loop. (#39422)
Close #39348

Now `NgZone` has an option `shouldCoalesceEventChangeDetection` to coalesce
multiple event handler's change detections to one async change detection.

And there are some cases other than `event handler` have the same issues.
In #39348, the case like this.

```
// This code results in one change detection occurring per
// ngZone.run() call. This is entirely feasible, and can be a serious
// performance issue.
for (let i = 0; i < 100; i++) {
  this.ngZone.run(() => {
    // do something
  });
}
```

So such kind of case will trigger multiple change detections.
And now with Ivy, we have a new `markDirty()` API will schedule
a requestAnimationFrame to trigger change detection and also coalesce
the change detections in the same event loop, `markDirty()` API doesn't
only take care `event handler` but also all other cases `sync/macroTask/..`

So this PR add a new option to coalesce change detections for all cases.

Kristiyan Kostadinov b015d3e950 fix(core): not inserting ViewContainerRef nodes when inside root of a component (#39599)
When a `ViewContainerRef` is injected, we dynamically create a comment node next to the host
so that it can be used as an anchor point for inserting views. The comment node is inserted
through the `appendChild` helper from `node_manipulation.ts` in most cases.

The problem with using `appendChild` here is that it has some extra logic which doesn't return
a parent `RNode` if an element is at the root of a component. I __think__ that this is a performance
optimization which is used to avoid inserting an element in one place in the DOM and then
moving it a bit later when it is projected. This can break down in some cases when creating
a `ViewContainerRef` for a non-component node at the root of another component like the following:

```
<root>
  <div #viewContainerRef></div>
</root>
```

In this case the `#viewContainerRef` node is at the root of a component so we intentionally don't
insert it, but since its anchor element was created manually, it'll never be projected. This will
prevent any views added through the `ViewContainerRef` from being inserted into the DOM.

These changes resolve the issue by not going through `appendChild` at all when creating a comment
node for `ViewContainerRef`. This should work identically since `appendChild` doesn't really do
anything with the T structures anyway, it only uses them to reach the relevant DOM nodes.

Fixes #39556.

Andrew Kushnir 1bc53eb303 fix(forms): more precise control cleanup (#39623)
Currently when an instance of the `FormControlName` directive is destroyed, the Forms package invokes
the `cleanUpControl` to clear all directive-specific logic (such as validators, onChange handlers,
etc) from a bound control. The logic of the `cleanUpControl` function should revert all setup
performed by the `setUpControl` function. However the `cleanUpControl` is too aggressive and removes
all callbacks related to the onChange and disabled state handling. This is causing problems when
a form control is bound to multiple FormControlName` directives, causing other instances of that
directive to stop working correctly when the first one is destroyed.

This commit updates the cleanup logic to only remove callbacks added while setting up a control
for a given directive instance.

The fix is needed to allow adding `cleanUpControl` function to other places where cleanup is needed
(missing this function calls in some other places causes memory leak issues).

Jessica Janiuk 290ea57a93 fix(core): Access injected parent values using SelfSkip (#39464)
In ViewEngine, SelfSkip would navigate up the tree to get tokens from
the parent node, skipping the child. This restores that functionality in
Ivy. In ViewEngine, if a special token (e.g. ElementRef) was not found
in the NodeInjector tree, the ModuleInjector was also used to lookup
that token. While special tokens like ElementRef make sense only in a
context of a NodeInjector, we preserved ViewEngine logic for now to
avoid breaking changes.

We identified 4 scenarios related to @SkipSelf and special tokens where
ViewEngine behavior was incorrect and is likely due to bugs. In Ivy this
is implemented to provide a more intuitive API. The list of scenarios
can be found below.

1. When Injector is used in combination with @Host and @SkipSelf on the
first Component within a module and the injector is defined in the
module, ViewEngine will get the injector from the module. In Ivy, it
does not do this and throws instead.

2. When retrieving a @ViewContainerRef while @SkipSelf and @Host are
present, in ViewEngine, it throws an exception. In Ivy it returns the
host ViewContainerRef.

3. When retrieving a @ViewContainerRef on an embedded view and @SkipSelf
is present, in ViewEngine, the ref is null. In Ivy it returns the parent
ViewContainerRef.

4. When utilizing viewProviders and providers, a child component that is
nested within a parent component that has @SkipSelf on a viewProvider
value, if that provider is provided by the parent component's
viewProviders and providers, ViewEngine will return that parent's
viewProviders value, which violates how viewProviders' visibility should
work. In Ivy, it retrieves the value from providers, as it should.

These discrepancies all behave as they should in Ivy and are likely bugs
in ViewEngine.

Pete Bacon Darwin 8d90c1ad97 refactor(compiler): store the `fullStart` location on `ParseSourceSpan`s (#39486)
The lexer is able to skip leading trivia in the `start` location of tokens.
This makes the source-span more friendly since things like elements
appear to begin at the start of the opening tag, rather than at the
start of any leading whitespace, which could include newlines.

But some tooling requires the full source-span to be available, such
as when tokenizing a text span into an Angular expression.

This commit simply adds the `fullStart` location to the `ParseSourceSpan`
class, and ensures that places where such spans are cloned, this
property flows through too.

Andrew Kushnir e96b379385 fix(forms): remove validators while cleaning up a control (#39234)
Prior to this commit, the `cleanUpControl` function (responsible for cleaning up control instance)
was not taking validators into account. As a result, these validators remain registered on a detached
form control instance, thus causing memory leaks. This commit updates the `cleanUpControl` function
logic to also run validators cleanup.

As a part of this change, the logic to setup and cleanup validators was refactored and moved to
separate functions (with completely opposite behavior), so that they can be reused in the future.

This commit doesn't add the `cleanUpControl` calls to all possible places, it just fixes the cases
where this function is being called, but doesn't fully perform a cleanup. The `cleanUpControl`
function calls will be added to other parts of code (to avoid more memory leaks) in a followup PR.

Kristiyan Kostadinov cbc0907bfd fix(compiler): preserve this.$event and this.$any accesses in expressions (#39323)
Currently expressions `$event.foo()` and `this.$event.foo()`, as well as `$any(foo)` and
`this.$any(foo)`, are treated as the same expression by the compiler, because `this` is considered
the same implicit receiver as when the receiver is omitted. This introduces the following issues:

1. Any time something called `$any` is used, it'll be stripped away, leaving only the first parameter.
2. If something called `$event` is used anywhere in a template, it'll be preserved as `$event`,
rather than being rewritten to `ctx.$event`, causing the value to undefined at runtime. This
applies to listener, property and text bindings.

These changes resolve the first issue and part of the second one by preserving anything that
is accessed through `this`, even if it's one of the "special" ones like `$any` or `$event`.
Furthermore, these changes only expose the `$event` global variable inside event listeners,
whereas previously it was available everywhere.

JiaLiPassion 4a8d5ae970 fix(core): markDirty() should only mark flags when really scheduling tick. (#39316)
Close #39296

Fix an issue that `markDirty()` will not trigger change detection.

The case is for example we have the following component.

```
export class AppComponent implements OnInit {
  constructor(private router: Router) {}

  ngOnInit() {
    this.router.events
      .pipe(filter((e) => e instanceof NavigationEnd))
      .subscribe(() => ɵmarkDirty(this));
  }
}

export class CounterComponent implements OnInit, OnDestroy {
  ngOnInit() {
    this.countSubject.pipe(takeUntil(this.destroy)).subscribe((count) => {
      this.count = count;
      ɵmarkDirty(this);
    });
  }
```

Then the app navigate from `AppComponent` to `CounterComponent`,
so there are 2 `markDirty()` call at in a row.

The `1st` call is from `AppComponent` when router changed, the
`2nd` call is from `CounterComponent.ngOnInit()`.

And the `markDirty()->scheduleTick()` code look like this

```
function scheduleTick(rootContext, flags) {
    const nothingScheduled = rootContext.flags === 0 /* Empty */;
    rootContext.flags |= flags;
    if (nothingScheduled && rootContext.clean == _CLEAN_PROMISE) {
      rootContext.schedule(() => {
	...
        if (rootContext.flags & RootContextFlags.DetectChanges)
          rootContext.flags &= ~RootContextFlags.DetectChanges;
          tickContext();

        rootContext.clean = _CLEAN_PROMISE;
        ...
      });
```

So in this case, the `1st` markDirty() will
1. set rootContext.flags = 1
2. before `tickContext()`, reset rootContext.flags = 0
3. inside `tickContext()`, it will call `CounterComponent.ngOnint()`,
   so the `2nd` markDirty() is called.
4. and the `2nd` scheduleTick is called, `nothingScheduled` is true,
   but rootContext.clean is not `_CLEAN_PROMISE` yet, since the `1st` markDirty tick
   is still running.
5. So nowhere will reset the `rootContext.flags`.
6. then in the future, any other `markDirty()` call will not trigger the tick, since
   `nothingScheduled` is always false.

So `nothingScheduled` means no tick is scheduled, `rootContext.clean === _CLEAN_PROMISE`
means no tick is running.
So we should set the flags to `rootContext` only when `no tick is scheudled or running`.

Currently `i18n` attributes are treated the same no matter if they have data bindings or not. This

static attributes and all other `i18n` attributes go through the old code path.

Fixes #38231.

JoostK 3c6edcdf93 fix(core): do not error when `ngDevMode` is undeclared (#39415)
In production mode, the `ngDevMode` global may not have been declared.
This is typically not a problem, as optimizers should have removed all
usages of the `ngDevMode` variables. This does however require the
bundler/optimizer to have been configured in a certain way, as to allow
for `ngDevMode` guarded code to be removed.

As an example, Terser can be configured to remove the `ngDevMode`
guarded code using the following configuration:

```js
const terserOptions = {
  // ...
  compress: {
    // ...
    global_defs: require('@angular/compiler-cli').GLOBAL_DEFS_FOR_TERSER,
  }
}
```

(Taken from https://github.com/angular/angular/issues/31595#issuecomment-519129090)

If this is not done, however, the bundle should still work (albeit with
larger code size due to missed tree-shaking opportunities). This commit
adds a check for whether `ngDevMode` has been declared, as it is a
top-level statement that executes before `ngDevMode` has been initialized.

Bjarki 49197d12a0 feat(core): create a Trusted Types policy for bypass conversions (#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.

Bjarki 6e18d2dacc fix(compiler): promote constants in templates to Trusted Types (#39211)
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.

Chrome currently does not support passing TrustedScript to the Function
constructor, and instead fails with a Trusted Types violation when

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.

Updates to rules_nodejs 2.2.0. This is the first major release in 7 months and includes a number of features as well
as breaking changes.

Release notes: https://github.com/bazelbuild/rules_nodejs/releases/tag/2.0.0

Features of note for angular/angular:

* stdout/stderr/exit code capture; this could be potentially be useful

* TypeScript (ts_project); a simpler tsc rule that ts_library that can be used in the repo where ts_library is too
  heavy weight

Breaking changes of note for angular/angular:

* loading custom rules from npm packages: `ts_library` is no longer loaded from `@npm_bazel_typescript//:index.bzl`
  (which no longer exists) but is now loaded from `@npm//@bazel/typescript:index.bzl`

* with the loading changes above, `load("@npm//:install_bazel_dependencies.bzl", "install_bazel_dependencies")` is
  no longer needed in the WORKSPACE which also means that yarn_install does not need to run unless building/testing
  a target that depends on @npm. In angular/angular this is a minor improvement as almost everything depends on @npm.

* @angular/bazel package is also updated in this PR to support the new load location; Angular + Bazel users that
  require it for ng_package (ng_module is no longer needed in OSS with Angular 10) will need to load from
  `@npm//@angular/bazel:index.bzl`. I investigated if it was possible to maintain backward compatability for the old
  load location `@npm_angular_bazel` but it is not since the package itself needs to be updated to load from
  `@npm//@bazel/typescript:index.bzl` instead of `@npm_bazel_typescript//:index.bzl` as it depends on ts_library
  internals for ng_module.

* runfiles.resolve will now throw instead of returning undefined to match behavior of node require

Other changes in angular/angular:

* integration/bazel has been updated to use both ng_module and ts_libary with use_angular_plugin=true.
  The latter is the recommended way for rules_nodejs users to compile Angular 10 with Ivy. Bazel + Angular ViewEngine is
  supported with @angular/bazel <= 9.0.5 and Angular <= 8. There is still Angular ViewEngine example on rules_nodejs
  https://github.com/bazelbuild/rules_nodejs/tree/stable/examples/angular_view_engine on these older versions but users
  that want to update to Angular 10 and are on Bazel must switch to Ivy and at that point ts_library with
  use_angular_plugin=true is more performant that ng_module. Angular example in rules_nodejs is configured this way
  as well: https://github.com/bazelbuild/rules_nodejs/tree/stable/examples/angular. As an aside, we also have an
  example of building Angular 10 with architect() rule directly instead of using ts_library with angular plugin:
  https://github.com/bazelbuild/rules_nodejs/tree/stable/examples/angular_bazel_architect.

NB: ng_module is still required for angular/angular repository as it still builds ViewEngine & @angular/bazel
also provides the ng_package rule. ng_module can be removed in the future if ViewEngine is no longer needed in
angular repo.

* JSModuleInfo provider added to ng_module. this is for forward compat for future rules_nodejs versions.

  that want to update to Angular 10 and are on Bazel must switch to Ivy and at that point ts_library with
  use_angular_plugin=true is more performant that ng_module. Angular example in rules_nodejs is configured this way
  as well: https://github.com/bazelbuild/rules_nodejs/tree/stable/examples/angular. As an aside, we also have an
  example of building Angular 10 with architect() rule directly instead of using ts_library with angular plugin:
  https://github.com/bazelbuild/rules_nodejs/tree/stable/examples/angular_bazel_architect.

NB: ng_module is still required for angular/angular repository as it still builds ViewEngine & @angular/bazel
also provides the ng_package rule. ng_module can be removed in the future if ViewEngine is no longer needed in
angular repo.

* JSModuleInfo provider added to ng_module. this is for forward compat for future rules_nodejs versions.
  @josephperrott, this touches `packages/bazel/src/external.bzl` which will make the sync to g3 non-trivial.

Doug Parker 889470663d fix(core): use single quotes for relative link resolution migration to align with style guide (#39070)
This updates the migration to align with the style guide and work with default lint rules. It avoids a lint error on
newly migrated projects and fixes a test in the CLI repo.

Misko Hevery 494a2f3be4 refactor(core): Create `NodeInjectorOffset` type which better describes NodeInjector (#38707)
`NodeInjector` is store in expando as a list of values in an array. The

`NodeInjectorOffset` enum with better documentation explaining their usage.

Misko Hevery 7bd18fca19 refactor(core): change `getPreviousOrParentTNode` to return `TNode|null` (#38707)
This change makes `getPreviousOrParentTNode` return `TNode|null` (rather
than just `TNode`) which is more reflective of the reality. The
`getPreviousOrParentTNode` can be `null` upon entering the `LView`.

Misko Hevery eb32b6bd6b refactor(core): Remove reliance on `TNodeType.View`. (#38707)
`TNodeType.View` was created to support inline views. That feature did
not materialize and we have since removed the instructions for it, leave
 an unneeded `TNodeType.View` which was still used in a very
 inconsistent way. This change no longer created `TNodeType.View` (and
 there will be a follow up chang to completely remove it.)

Also simplified the mental model so that `LView[HOST]`/`LView[T_HOST]`
always point to the insertion location of the `LView`.

Misko Hevery 9fb541787c refactor(core): Remove host `TNode` from `getOrCreateTNode` (#38707)
Host `TNode` was passed into `getOrCreateTNode` just so that we can
compute weather or not we are a root node. This was needed because
`previousOrParentTNode` could have `TNode` from `TView` other then
current `TView`. This is confusing mental model. Previous change
ensured that `previousOrParentTNode` must always be part of `TView`,
which enabled this change to remove the unneeded argument.

Misko Hevery 812615bb99 refactor(core): Ensure that `previousOrParentTNode` always belongs to current `TView`. (#38707)
`previousOrParentTNode` stores current `TNode`. Due to inconsistent
implementation the value stored would sometimes belong to the current
`TView` and sometimes to the parent. We have extra logic which accounts
for it. A better solution is to just ensure that `previousOrParentTNode`
always belongs to current `TNode`. This simplifies the mental model
and cleans up some code.
