The injector system uses a bloom filter to determine if a token is
possibly defined in the node injector tree, which is stored across
multiple bloom buckets that each represent 32 bits of the full 256-bit
wide bloom hash. This means that a computation is required to determine
the exact bloom bucket which is responsible for storing any given 32-bit
interval, which was previously computed using three bitmask operations
and three branches to derive the bloom bucket offset.
This commit exploits the observation that all bits beyond the low 5 bits
of the bloom hash are an accurate representation for the bucket offset,
if shifted right such that those bits become the least significant bits.
This reduces the three bitmask operations and three branches with a
single shift operation, while additionally offering a code size
improvement.

Previous implementation would fire changes `QueryList.changes.subscribe`
whenever the `QueryList` was recomputed. This resulted in artificially
high number of change notifications, as it is possible that recomputing
`QueryList` results in the same list. When the `QueryList` gets recomputed
is an implementation detail and it should not be the thing which determines
how often change event should fire.
This change introduces a new `emitDistinctChangesOnly` option for
`ContentChildren` and `ViewChildren`.
```
export class QueryCompWithStrictChangeEmitParent {
@ContentChildren('foo', {
// This option will become the default in the future
emitDistinctChangesOnly: true,
})
foos!: QueryList<any>;
}

This does not work in the 'root' injector as the provider overrides the

Occasionally, the SW would end up in a broken state where some of the
eagerly cached resources of an older version were available in the local
cache, but others (such as lazy-loaded bundles) were not. This would
leave the app in a broken state and a blank screen would be displayed.
See #28114 for a more detailed discussion.
This commit takes advantage of the newly introduced (in v11)
[SwUpdate#unrecoverable][1] API to detect these bad states and recover
by doing a full page reload whenever an [UnrecoverableStateEvent][2] is
emitted.
Partially addresses #28114.
NOTE:
Currently, `SwUpdate.unrecoverable` only works if the app has already
bootstrapped; i.e. if only lazy-loaded bundles have been purged from the
cache.
That should be fine in practice, since the cache entries are removed in
least-recently-used order. Thus the eagerly loaded bundles will be the
last to be removed from the cache (which rarely happens in practice).

Previously, the `LocationService` depended on the `SwUpdatesService`.
This felt backwards, since `LocationService` is a more low-level and

higher-level, specific feature (ServiceWorkers).
This commit inverses the relation, making `SwUpdatesService` depend on
`LocationService` instead.

As with regular Angular components, Angular elements are expected to
have their views update when inputs change.
Previously, Angular Elements views were not updated if the underlying

This commit fixes this by calling `markForCheck()` on the component
view's `ChangeDetectorRef`.

Currently we read lifecycle hooks eagerly during `ɵɵdefineComponent`.
The result is that it is not possible to do any sort of meta-programing
such as mixins or adding lifecycle hooks using custom decorators since
any such code executes after `ɵɵdefineComponent` has extracted the
lifecycle hooks from the prototype. Additionally the behavior is
inconsistent between AOT and JIT mode. In JIT mode overriding lifecycle
hooks is possible because the whole `ɵɵdefineComponent` is placed in
getter which is executed lazily. This is because JIT mode must compile a
template which can be specified as `templateURL` and those we are
waiting for its resolution.
- `+` `ɵɵdefineComponent` becomes smaller as it no longer needs to copy
lifecycle hooks from prototype to `ComponentDef`
- `-` `ɵɵNgOnChangesFeature` feature is now always included with the
codebase as it is no longer tree shakable.
Previously we have read lifecycle hooks from prototype in the
`ɵɵdefineComponent` so that lifecycle hook access would be monomorphic.
This decision was made before we had `T*` data structures. By not
reading the lifecycle hooks we are moving the megamorhic read form
`ɵɵdefineComponent` to instructions. However, the reads happen on
`firstTemplatePass` only and are subsequently cached in the `T*` data
structures. The result is that the overall performance should be same
(or slightly better as the intermediate `ComponentDef` has been
removed.)
- [ ] Remove `ɵɵNgOnChangesFeature` from compiler. (It will no longer
be a feature.)
- [ ] Discuss the future of `Features` as they hinder meta-programing.

As of TypeScript 3.9, the tsc emit is not compatible with Closure
Compiler due to
https://github.com/microsoft/TypeScript/pull/32011.
There is some hope that this will be fixed by a solution like the one
proposed in
https://github.com/microsoft/TypeScript/issues/38374 but currently it's
unclear if / when that will
happen.
Since the Closure support has been somewhat already broken, and the
tsickle pass has been a source
of headaches for some time for Angular packages, we are removing it for
now while we rethink our
strategy to make Angular Closure compatible outside of Google.
This change has no effect on our Closure compatibility within Google
which work well because all the
code is compiled from sources and passed through tsickle.
This change only disables the tsickle pass but doesn't remove it.
A follow up PR should either remove all the traces of tscikle or
re-enable the fixed version.
BREAKING CHANGE: Angular npm packages no longer contain jsdoc comments
to support Closure Compiler's advanced optimizations
The support for Closure compiler in Angular packages has been
experimental and broken for quite some
time.
As of TS3.9 Closure is unusable with the JavaScript emit. Please follow
https://github.com/microsoft/TypeScript/issues/38374 for more
information and updates.
If you used Closure compiler with Angular in the past, you will likely
be better off consuming
Angular packages built from sources directly rather than consuming the
version we publish on npm
which is primarily optimized for Webpack/Rollup + Terser build pipeline.
As a temporary workaround you might consider using your current build
pipeline with Closure flag
`--compilation_level=SIMPLE`. This flag will ensure that your build
pipeline produces buildable and
runnable artifacts, at the cost of increased payload size due to
advanced optimizations being disabled.
If you were affected by this change, please help us understand your
needs by leaving a comment on https://github.com/angular/angular/issues/37234.

Only refresh transplanted views at the insertion location in Ivy.
Previously, Ivy would check transplanted views at both the insertion and
declaration points. This is achieved by adding a marker to the insertion
tree when we encounter a transplanted view that needs to be refreshed at
its declaration. We use this marker as an extra indication that we still
need to descend and refresh those transplanted views at their insertion
locations even if the insertion view and/or its parents are not dirty.
This change fixes several issues:
* Transplanted views refreshed twice if both insertion and declaration
are dirty. This could be an error if the insertion component changes
result in data not being available to the transplanted view because it
is slated to be removed.
* CheckAlways transplanted views not refreshed if shielded by
non-dirty OnPush (fixes#35400)
* Transplanted views still refreshed when insertion tree is detached
(fixes#21324)
