pkozlowski-opensource bbe3543c69 refactor(core): remove duplicated WrappedValue class (#37940)
Before this refactoring we had the WrappedValue class in
2 separate places:
- packages/core/src/change_detection/change_detection_util.ts
- packages/core/src/util/WrappedValue.ts

This commit removes the duplicate, leaving the class that has
the deprecation notice.

Pete Bacon Darwin ec32eba02c feat(localize): expose `canParse()` diagnostics (#37909)
When loading a translation file we ask each `TranslationParser`
whether it can parse the file. Occasionally, this check can find
errors in the file that would be useful to the developer. For example
if the file has invalid XML.

This commit deprecates the previous `canParse()` method and replaces it
with a new `analyze()` method. This returns an object that includes a
boolean `canParse` and then either a `hint` if it can parse the file,
or a `diagnostics` object filled with any messages that can be used to
diagnose problems with the format of the file.

Andrew Kushnir aed6b131bb fix(core): handle spaces after `select` and `plural` ICU keywords (#37866)
Currently when the `plural` or `select` keywords in an ICU contain trailing spaces (e.g. `{count, select , ...}`), these spaces are also included into the key names in ICU vars (e.g. "VAR_SELECT "). These trailing spaces are not desirable, since they will later be converted into `_` symbols while normalizing placeholder names, thus causing mismatches at runtime (i.e. placeholder will not be replaced with the correct value). This commit updates the code to trim these spaces while generating an object with placeholders, to make sure the runtime logic can replace these placeholders with the right values.

Dmitrij Kuba d7dd2959c8 perf(router): apply prioritizedGuardValue operator to optimize CanLoad guards (#37523)
CanLoad guards are processed in asynchronous manner with the following rules:
* If all guards return `true`, operator returns `true`;
* `false` and `UrlTree` values wait for higher priority guards to resolve;
* Highest priority `false` or `UrlTree` value will be returned.

`prioritizedGuardValue` uses `combineLatest` which in order subscribes to each Observable immediately (not waiting when previous one completes that `concatAll` do). So it makes some advantages in order to run them concurrently. Respectively, a time to resolve all guards will be reduced.

Andrew Scott a5ffca0576 fix(router): fix navigation ignoring logic to compare to the browser url (#37716)
This PR changes the logic for determining when to skip route processing from
using the URL of the last attempted navigation to the actual resulting URL after
that transition.

Because guards may prevent navigation and reset the browser URL, the raw
URL of the previous transition may not match the actual URL of the
browser at the end of the navigation process. For that reason, we need to use
`urlAfterRedirects` instead.

Other notes:
These checks in scheduleNavigation were added in eb2ceff4ba
The test still passes and, more surprisingly, passes if the checks are removed
completely. There have likely been changes to the navigation handling that
handle the test in a different way. That said, it still appears to be important
to keep the checks there in some capacity because it does affect how many
navigation events occur. This addresses an issue that came up in #16710: https://github.com/angular/angular/issues/16710#issuecomment-634869739
This also partially addresses #13586 in fixing history for imperative
navigations that are cancelled by guards.

Alex Rickabaugh 71956250dd perf(compiler-cli): fix memory leak in retained incremental state (#37835)
Incremental compilation allows for the output state of one compilation to be
reused as input to the next compilation. This involves retaining references
to instances from prior compilations, which must be done carefully to avoid
memory leaks.

This commit fixes such a leak with a complicated retention chain:

* `TrackedIncrementalBuildStrategy` unnecessarily hangs on to the previous
  `IncrementalDriver` (state of the previous compilation) once the current
  compilation completes.

  In general this is unnecessary, but should be safe as long as the chain
  only goes back one level - if the `IncrementalDriver` doesn't retain any
  previous `TrackedIncrementalBuildStrategy` instances. However, this does
  happen:

* `NgCompiler` indirectly causes retention of previous `NgCompiler`
  instances (and thus previous `TrackedIncrementalBuildStrategy` instances)
  through accidental capture of the `this` context in a closure created in
  its constructor. This closure is wrapped in a `ts.ModuleResolutionCache`
  used to create a `ModuleResolver` class, which is passed to the program's
  `TraitCompiler` on construction.

* The `IncrementalDriver` retains a reference to the `TraitCompiler` of the
  previous compilation, completing the reference chain.

The final retention chain thus looks like:

* `TrackedIncrementalBuildStrategy` of current program
* `.previous`: `IncrementalDriver` of previous program
* `.lastGood.traitCompiler`: `TraitCompiler`
* `.handlers[..].moduleResolver.moduleResolutionCache`: cache
* (via `getCanonicalFileName` closure): `NgCompiler`
* `.incrementalStrategy`: `TrackedIncrementalBuildStrategy` of previous
  program.

The closure link is the "real" leak here. `NgCompiler` is creating a closure
for `getCanonicalFileName`, delegating to its
`this.adapter.getCanonicalFileName`, for the purposes of creating a
`ts.ModuleResolutionCache`. The fact that the closure references
`NgCompiler` thus eventually causes previous `NgCompiler` iterations to be
retained. This is also potentially problematic due to the shared nature of
`ts.ModuleResolutionCache`, which is potentially retained across multiple
compilations intentionally.

This commit fixes the first two links in the retention chain: the build
strategy is patched to not retain a `previous` pointer, and the `NgCompiler`
is patched to not create a closure in the first place, but instead pass a
bound function. This ensures that the `NgCompiler` does not retain previous
instances of itself in the first place, even if the build strategy does
end up retaining the previous incremental state unnecessarily.

The third link (`IncrementalDriver` unnecessarily retaining the whole
`TraitCompiler`) is not addressed in this commit as it's a more
architectural problem that will require some refactoring. However, the leak
potential of this retention is eliminated thanks to fixing the first two
issues.

PR https://github.com/angular/angular/pull/37523 failed when trying to use `rxjs delay` operator
inside `fakeAsync`, and the reasons are:

1. we need to import `rxjs-fake-async` patch to make the integration work.
2. since in `angular` repo, the bazel target `/tools/testing:node` not using `zone-testing` bundle,
instead it load `zone-spec` packages seperately, so it causes one issue which is the `zone.js/testing/fake-async`
package is not loaded, we do have a fallback logic under `packages/core/testing` calles `fake_async_fallback`,
but the logic is out of date with `fake-async` under `zone.js` package.

`fake-async`. And I will make another PR to try to remove the `fallback` logic.

JiaLiPassion c2b4d92708 feat(zone.js): patch jasmine.createSpyObj to make properties enumerable to be true (#34624)
Close #33657

in jasmine 3.5, there is a new feature, user can pass a properties object to `jasmine.createSpyObj`

```
const spy = jasmine.createSpyObj('spy', ['method1'], {prop1: 'foo'});
expect(spy.prop1).toEqual('foo');
```

This case will not work for Angular TestBed, for example,

```
describe('AppComponent', () => {
  beforeEach(() => {

    //Note the third parameter
    // @ts-ignore
    const someServiceSpy = jasmine.createSpyObj('SomeService', ['someFunction'], ['aProperty']);

    TestBed.configureTestingModule({
      declarations: [
        AppComponent
      ],
      providers: [
        {provide: SomeService, useValue: someServiceSpy},
      ]
    }).compileComponents();

  });

  it('should create the app', () => {
    //spyObj will have someFunction, but will not have aProperty
    let spyObj = TestBed.get(SomeService);
  });
```

Because `jasmine.createSpyObj` will create the `aProperty` with `enumerable=false`,
and `TestBed.configureTestingModule` will try to copy all the properties from spyObj to
the injected service instance. And because `enumerable` is false, so the property (here is aProperty)
will not be copied.

This PR will monkey patch the `jasmine.createSpyObj` and make sure the new property's
`enumerable=true`.

JoostK a87951a28f fix(ngcc): prevent including JavaScript sources outside of the package (#37596)
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.

George Kalpakas eba9dd364e fix(elements): fire custom element output events during component initialization (#37570)
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).

Harri Lehtola b950d4675f fix(core): do not trigger CSP alert/report in Firefox and Chrome (#36578) (#36578)
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
those scenarios.

Paul Gschwendtner d12cdb5019 fix(migrations): do not incorrectly add todo for @Injectable or @Pipe (#37732)
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).

JoostK 712f1bd0b7 feat(compiler-cli): explain why an expression cannot be used in AOT compilations (#37587)
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.

   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.

Pete Bacon Darwin 9318e23e64 perf(ngcc): use `EntryPointManifest` to speed up noop `ProgramBaseEntryPointFinder` (#37665)
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.

Paul Gschwendtner 1601ee6f6a refactor(dev-infra): ng_rollup_bundle rule should leverage `@bazel/rollup` (#37623)
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.

As of Angular Package Format v10, we no longer ship a `fesm5` and
`fesm5` output in packages. We made this change to the `ng_package`
rule but intentionally did not clean up related build actions.

This follow-up commit cleans this up by:

* No longer building fesm5 bundles, or providing esm2015 output.
* No longer requesting and building a third flavor for ESM5. We can
use TSC to downlevel ES2015 sources/prodmode output similarly to how it
is done in `ng-packagr`.

The third output flavor (ESM5) resulted in a build slow-down as we
required a full recompilation of sources. Now, we only have a single
compilation for prodmode output, and then downlevel it on-demand
to ES5 for the UMD bundles. Here is timing for building the release
packages in `angular/angular` before this change, and afterwards:

* Before: 462.157s = ~7.7min
* After: 339.703s =  ~5.6min

Paul Gschwendtner 66e6b932d8 refactor(compiler-cli): skip class decorators in tooling constructor parameters transform (#37545)
We recently added a transformer to NGC that is responsible for downleveling Angular
decorators and constructor parameter types. The primary goal was to mitigate a
TypeScript limitation/issue that surfaces in Angular projects due to the heavy
reliance on type metadata being captured for DI. Additionally this is a pre-requisite
of making `tsickle` optional in the Angular bazel toolchain.

See: 401ef71ae5 for more context on this.

Another (less important) goal was to make sure that the CLI can re-use
this transformer for its JIT mode compilation. The CLI (as outlined in
the commit mentioned above), already has a transformer for downleveling
constructor parameters. We want to avoid this duplication and exported
the transform through the tooling-private compiler entry-point.

Early experiments in using this transformer over the current one, highlighted
that in JIT, class decorators cannot be downleveled. Angular relies on those
to be invoked immediately for JIT (so that factories etc. are generated upon loading)

The transformer we exposed, always downlevels such class decorators
though, so that would break CLI's JIT mode. We can address the CLI's
needs by adding another flag to skip class decorators. This will allow
us to continue with the goal of de-duplication.

Alex Rickabaugh 300c2fec9c refactor(compiler-cli): make IncrementalBuild strategy configurable (#37339)
Commit 24b2f1da2b introduced an `NgCompiler` which operates on a
`ts.Program` independently of the `NgtscProgram`. The NgCompiler got its
`IncrementalDriver` (for incremental reuse of Angular compilation results)
by looking at a monkey-patched property on the `ts.Program`.

This monkey-patching operation causes problems with the Angular indexer
(specifically, it seems to cause the indexer to retain too much of prior
programs, resulting in OOM issues). To work around this, `IncrementalDriver`
reuse is now handled by a dedicated `IncrementalBuildStrategy`. One
implementation of this interface is used by the `NgtscProgram` to perform
the old-style reuse, relying on the previous instance of `NgtscProgram`
instead of monkey-patching. Only for `NgTscPlugin` is the monkey-patching
strategy used, as the plugin sits behind an interface which only provides
access to the `ts.Program`, not a prior instance of the plugin.

Doug Parker 1091ddbb8e build(bazel): check for renderer flag in `ng_module()` (#37529)
This checks for a Bazel flag in `ng_module()` in the `_renderer` attribute
which specifies the renderer to use for the build.

The main advantage of this flag is that it can be overridden with [Bazel
transitions](https://docs.bazel.build/versions/master/skylark/config.html),
giving much more flexibility for migrating individual applications in a
Bazel workspace to Ivy.

This flag is not intended to replace `--config ivy` or
`--define angular_ivy_enabled=True` (although it technically could). As a
result, this flag is not and will not actually be used anywhere in the
`angular/angular` repo. Instead, a `string_flag()` is provided  internally
which sets the renderer via a transition. See http://cl/315749946.

Note that this does **not** introduce a dependency on Skylib for
`angular/angular`. The dependency isn't actually necessary because
`BuildSettingInfo` is not used externally anyways. By doing this, it is not
necessary for downstream, external workspaces to depend on Skylib.

Because guards may prevent navigation and reset the browser URL, the raw

George Kalpakas bf682d73d4 fix(ngcc): correctly get config for packages in nested `node_modules/` (#37040)
Previously, ngcc would only be able to match an ngcc configuration to
packages that were located inside the project's top-level
`node_modules/`. However, if there are multiple versions of a package in
a project (e.g. as a transitive dependency of other packages), multiple
copies of a package (at different versions) may exist in nested
`node_modules/` directories. For example, one at
`<project-root>/node_modules/some-package/` and one at
`<project-root>/node_modules/other-package/node_modules/some-package/`.
In such cases, ngcc was only able to detect the config for the first
copy but not for the second.

This commit fixes this by returning a new instance of
`ProcessedNgccPackageConfig` for each different package path (even if
they refer to the same package name). In these
`ProcessedNgccPackageConfig`, the `entryPoints` paths have been
processed to take the package path into account.

George Kalpakas 829ddf95e5 fix(ngcc): correctly retrieve a package's version from its `package.json` (#37040)
In order to retrieve the ngcc configuration (if any) for an entry-point,
ngcc has to detect the containing package's version.

Previously, ngcc would try to read the version from the entry-point's
`package.json` file, which was different than the package's top-level
`package.json` for secondary entry-points. For example, it would try to
read it from `node_modules/@angular/common/http/package.json` for
entry-point `@angular/common/http`. However, the `package.json` files
for secondary entry-points are not guaranteed to include a `version`
property.

This commit fixes this by first trying to read the version from the
_package's_ `package.json` (falling back to the entry-point's
`package.json`). For example, it will first try to read it from
`@angular/common/package.json` for entry-point `@angular/common/http`.

George Kalpakas e7a0e87c41 fix(ngcc): correctly get config for sub-entry-points when primary entry-point is ignored (#37040)
Previously, when an entry-point was ignored via an ngcc config, ngcc
would scan sub-directories for sub-entry-points, but would not use the
correct `packagePath`. For example, if `@angular/common` was ignored, it
would look at `@angular/common/http` but incorrectly use
`.../@angular/common/http` as the `packagePath` (instead of
`.../@angular/common`). As a result, it would not retrieve the correct
ngcc config for the actual package.

This commit fixes it by ensuring the correct `packagePath` is used, even
if the primary entry-point corresponding to that path is ignored. In
order to do this, a new return value for `getEntryPointInfo()` is added:
`IGNORED_ENTRY_POINT`. This is used to differentiate between directories
that correspond to no or an incompatible entry-point and those that
correspond to an entry-point that could otherwise be valid but is
explicitly ignored. Consumers of `getEntryPointInfo()` can then use this
info to discard ignored entry-points, but still use the correct
`packagePath` when scanning their sub-directories for secondary
entry-points.

JiaLiPassion 31796e8e2f fix(zone.js): remove unused Promise overwritten setter logic (#36851)
In the early Zone.js versions (< 0.10.3), `ZoneAwarePromise` did not support `Symbol.species`,
so when user used a 3rd party `Promise` such as `es6-promise`, and try to load the promise library after import of `zone.js`, the loading promise library will overwrite the patched `Promise` from `zone.js` and will break `Promise` semantics with respect to `zone.js`.

Starting with `zone.js` 0.10.3, `Symbol.species` is supported therefore this will not longer be an issue. (https://github.com//pull/34533)

Before 0.10.3, the logic in zone.js tried to handle the case in the wrong way. It did so by overriding the descriptor of `global.Promise`, to allow the 3rd party libraries to override native `Promise` instead of `ZoneAwarePromise`. This is not the correct solution, and since the `Promise.species` is now supported, the 3rd party solution of overriding `global.Promise` is no longer needed.

PR removes the wrong work around logic. (This will improve the bundle size.)

JiaLiPassion 284123c6ba fix(core): should fake a top event task when coalescing events to prevent draining microTaskQueue too early. (#36841)
Close #36839.

This is a known issue of zone.js,

```
(window as any)[(Zone as any).__symbol__('setTimeout')](() => {
  let log = '';
  button.addEventListener('click', () => {
    Zone.current.scheduleMicroTask('test', () => log += 'microtask;');
    log += 'click;';
  });
  button.click();
  expect(log).toEqual('click;microtask;');
  done();
});
```

Since in this case, we use native `setTimeout` which is not a ZoneTask,
so zone.js consider the button click handler as the top Task then drain the
microTaskQueue after the click at once, which is not correct(too early).

This case was an edge case and not reported by the users, until we have the
new option ngZoneEventCoalescing, since the event coalescing will happen
in native requestAnimationFrame, so it will not be a ZoneTask, and zone.js will
consider any Task happen in the change detection stage as the top task, and if
there are any microTasks(such as Promise.then) happen in the process, it may be
drained earlier than it should be, so to prevent this situation, we need to schedule
a fake event task and run the change detection check in this fake event task,
so the Task happen in the change detection stage will not be
considered as top ZoneTask.

Paul Gschwendtner 97dc85ba5e feat(core): support injection token as predicate in queries (#37506)
Currently Angular internally already handles `InjectionToken` as
predicates for queries. This commit exposes this as public API as
developers already relied on this functionality but currently use
workarounds to satisfy the type constraints (e.g. `as any`).

We intend to make this public as it's low-effort to support, and
it's a significant key part for the use of light-weight tokens as
described in the upcoming guide: https://github.com/angular/angular/pull/36144.

In concrete, applications might use injection tokens over classes
for both optional DI and queries, because otherwise such references
cause classes to be always retained. This was also an issue in View
Engine, but now with Ivy, this pattern became worse, as factories are
directly attached to retained classes (ultimately ending up in the
production bundle, while being unused).

More details in the light-weight token guide and in: https://github.com/angular/angular-cli/issues/16866.

JiaLiPassion 583a9d38a1 feat(zone.js): upgrade zone.js to angular package format(APF) (#36540)
Close #35157

In the current version of zone.js, zone.js uses it's own package format, and it is not following the rule
of Angualr package format(APF), so it is not easily to be consumed by Angular CLI or other bundle tools.
For example, zone.js npm package has two bundles,

1. zone.js/dist/zone.js, this is a `es5` bundle.
2. zone.js/dist/zone-evergreen.js, this is a `es2015` bundle.

And Angular CLI has to add some hard-coding code to handle this case, o5376a8b139/packages/schematics/angular/application/files/src/polyfills.ts.template (L55-L58)

This PR upgrade zone.js npm package format to follow APF rule, https://docs.google.com/document/d/1CZC2rcpxffTDfRDs6p1cfbmKNLA6x5O-NtkJglDaBVs/edit#heading=h.k0mh3o8u5hx

The updated points are:

1. in package.json, update all bundle related properties

```
  "main": "./bundles/zone.umd.js",
  "module": "./fesm2015/zone.js",
  "es2015": "./fesm2015/zone.js",
  "fesm2015": "./fesm2015/zone.js",
```

2. re-organize dist folder, for example for `zone.js` bundle, now we have

```
  dist/
      bundles/
             zone.js            // this is the es5 bundle
      fesm2015/
             zone.js            // this is the es2015 bundle (in the old version is `zone-evergreen.js`)
```

3. have several sub-packages.

1. `zone-testing`, provide zone-testing bundles include zone.js and testing libraries
2. `zone-node`, provide zone.js implemention for NodeJS
3. `zone-mix`, provide zone.js patches for both Browser and NodeJS

All those sub-packages will have their own `package.json` and the bundle will reference `bundles(es5)` and `fesm2015(es2015)`.

4. keep backward compatibility, still keep the `zone.js/dist` folder, and all bundles will be redirected to `zone.js/bundles` or `zone.js/fesm2015` folders.

Pete Bacon Darwin ae364864f6 fix(ngcc): do not scan import expressions in d.ts files (#37503)
It is quite common for the TS compiler to have to add synthetic
types to function signatures, where the developer has not
explicitly provided them.  This results in `import(...)` expressions
appearing in typings files.  For example in `@ngrx/data` there is a
class with a getter that has an implicit type:

```ts
export declare class EntityCollectionServiceBase<...> {
  ...
  get store() {
    return this.dispatcher.store;
  }
  ...
}
```

In the d.ts file for this we get:

```ts
get store(): Store<import("@ngrx/data").EntityCache>;
```

Given that this file is within the `@ngrx/data` package already,
this caused ngcc to believe that there was a circular dependency,
causing it to fail to process the package - and in fact crash!

This commit resolves this problem by ignoring `import()` expressions
when scanning typings programs for dependencies. This ability was
only introduced very recently in a 10.0.0 RC release, and so it has
limited benefit given that up till now ngcc has been able to process
libraries effectively without it. Moreover, in the rare case that a
package does have such a dependency, it should get picked up
by the sync ngcc+CLI integration point.

Paul Gschwendtner 401ef71ae5 fix(compiler-cli): downlevel angular decorators to static properties (#37382)
In v7 of Angular we removed `tsickle` from the default `ngc` pipeline.
This had the negative potential of breaking ES2015 output and SSR due
to a limitation in TypeScript.

TypeScript by default preserves type information for decorated constructor
parameters when `emitDecoratorMetadata` is enabled. For example,
consider this snippet below:

```
@Directive()
export class MyDirective {
  constructor(button: MyButton) {}
}

export class MyButton {}
```

TypeScript would generate metadata for the `MyDirective` class it has
a decorator applied. This metadata would be needed in JIT mode, or
for libraries that provide `MyDirective` through NPM. The metadata would
look as followed:

```
let MyDirective = class MyDir {}

MyDirective = __decorate([
  Directive(),
  __metadata("design:paramtypes", [MyButton]),
], MyDirective);

let MyButton = class MyButton {}
```

Notice that TypeScript generated calls to `__decorate` and
`__metadata`. These calls are needed so that the Angular compiler
is able to determine whether `MyDirective` is actually an directive,
and what types are needed for dependency injection.

The limitation surfaces in this concrete example because `MyButton`
is declared after the `__metadata(..)` call, while `__metadata`
actually directly references `MyButton`. This is illegal though because
`MyButton` has not been declared at this point. This is due to the
so-called temporal dead zone in JavaScript. Errors like followed will
be reported at runtime when such file/code evaluates:

```
Uncaught ReferenceError: Cannot access 'MyButton' before initialization
```

As noted, this is a TypeScript limitation because ideally TypeScript
shouldn't evaluate `__metadata`/reference `MyButton` immediately.
Instead, it should defer the reference until `MyButton` is actually
declared. This limitation will not be fixed by the TypeScript team
though because it's a limitation as per current design and they will
only revisit this once the tc39 decorator proposal is finalized
(currently stage-2 at time of writing).

Given this wontfix on the TypeScript side, and our heavy reliance on
this metadata in libraries (and for JIT mode), we intend to fix this
from within the Angular compiler by downleveling decorators to static
properties that don't need to evaluate directly. For example:

```
MyDirective.ctorParameters = () => [MyButton];
```

With this snippet above, `MyButton` is not referenced directly. Only
lazily when the Angular runtime needs it. This mitigates the temporal
dead zone issue caused by a limitation in TypeScript's decorator
metadata output. See: https://github.com/microsoft/TypeScript/issues/27519.

In the past (as noted; before version 7), the Angular compiler by
default used tsickle that already performed this transformation. We
moved the transformation to the CLI for JIT and `ng-packager`, but now
we realize that we can move this all to a single place in the compiler
so that standalone ngc consumers can benefit too, and that we can
disable tsickle in our Bazel `ngc-wrapped` pipeline (that currently
still relies on tsickle to perform this decorator processing).

This transformation also has another positive side-effect of making
Angular application/library code more compatible with server-side
rendering. In principle, TypeScript would also preserve type information
for decorated class members (similar to how it did that for constructor
parameters) at runtime. This becomes an issue when your application
relies on native DOM globals for decorated class member types. e.g.

```
@Input() panelElement: HTMLElement;
```

Your application code would then reference `HTMLElement` directly
whenever the source file is loaded in NodeJS for SSR. `HTMLElement`
does not exist on the server though, so that will become an invalid
reference. One could work around this by providing global mocks for
these DOM symbols, but that doesn't match up with other places where
dependency injection is used for mocking DOM/browser specific symbols.

More context in this issue: #30586. The TL;DR here is that the Angular
compiler does not care about types for these class members, so it won't
ever reference `HTMLElement` at runtime.

This PR provides a more helpful error than the one currently present:
`el.setAttribute is not a function`. It is not valid to have directives with host bindings
on `ng-template` or `ng-container` nodes. VE would silently ignore this, while Ivy

and do not have `setAttribute` functionality.

It is better to throw a helpful error than to silently ignore this because
putting a directive with host binding on an `ng-template` or `ng-container` is most often a mistake.
Developers should be made aware that the host binding will have no effect in these cases.

Note that an error is already thrown in Ivy, as mentioned above, so this
is not a breaking change and can be merged to both master and patch.

Test scenarios should be colocated with the test cases themselves.
Besides, many existing cases are invalid. For example, if we want to
test autocomplete for HTML element, the existing test case is like:
```
<~{cursor} h1>
```
This doesn't make much sense, becasue the language service already sees
the `h1` tag in the template. The correct test case should be:
```
<~{cursor
```
IMO, this reflects the real-world use case better.

This commit also uncovers a bug in the way HTML entities autocompletion
is done. There's an off-by-one error in which a cursor that immediately
trails the ampersand character fails to trigger HTML entities
autocompletion.

Adrien Vergé d63ecf4c5f fix(service-worker): Don't stay locked in EXISTING_CLIENTS_ONLY if corrupted data (#37453)
**Problem**

After #31109 and #31865, it's still possible to get locked in state
`EXISTING_CLIENTS_ONLY`, without any possibility to get out (even by
pushing new updates on the server).
More specifically, if control doc `/latest` of `ngsw:/:db:control` once
gets a bad value, then the service worker will fail early, and won't be
able to overwrite `/latest` with new, valid values (the ones from future
updates).

For example, once in this state, URL `/ngsw/state` will show:

    NGSW Debug Info:
    Driver state: EXISTING_CLIENTS_ONLY (Degraded due to failed initialization: Invariant violated (initialize): latest hash 8b75… has no known manifest
    Error: Invariant violated (initialize): latest hash 8b75… has no known manifest
        at Driver.<anonymous> (https://my.app/ngsw-worker.js:2302:27)
        at Generator.next (<anonymous>)
        at fulfilled (https://my.app/ngsw-worker.js:175:62))
    Latest manifest hash: 8b75…
    Last update check: 22s971u

... with hash `8b75…` corresponding to no installed version.

**Solution**

Currently, when such a case happens, the service worker [simply fails
with an assertion][1]. Because this failure happens early, and is not
handled, the service worker is not able to update `/latest` to new
installed app versions.

I propose to detect this corrupted case (a `latest` hash that doesn't
match any installed version) a few lines above, so that the service
worker can correctly call its [already existing cleaning code][2].

George Kalpakas 2a330a60ed fix(elements): fire custom element output events during component initialization (#36161)
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 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. Ensuring `NgElementImpl` subscribes to `NgElementStrategy#events`
   before calling `NgElementStrategy#connect()` (which initializes the
   component instance).

It is triggered by calling `mainNgcc()` with the `findEntryPointsFromTsConfigProgram`

It is triggered from the command line by adding the `--use-program-dependencies`

Alex Rickabaugh e648a0c4ca refactor(compiler-cli): extract NgCompilerAdapter interface (#37118)
`NgCompiler` is the heart of ngtsc and can be used to analyze and compile
Angular programs in a variety of environments. Most of these integrations
rely on `NgProgram` and the creation of an `NgCompilerHost` in order to
create a `ts.Program` with the right shape for `NgCompiler`.

However, certain environments (such as the Angular Language Service) have
their own mechanisms for creating `ts.Program`s that don't make use of a
`ts.CompilerHost`. In such environments, an `NgCompilerHost` does not make
sense.

This commit breaks the dependency of `NgCompiler` on `NgCompilerHost` and
extracts the specific interface of the host on which `NgCompiler` depends
into a new interface, `NgCompilerAdapter`. This interface includes methods
from `ts.CompilerHost`, the `ExtendedTsCompilerHost`, as well as APIs from
`NgCompilerHost`.

A consumer such as the language service can implement this API without
needing to jump through hoops to create an `NgCompilerHost` implementation
that somehow wraps its specific environment.

Alex Rickabaugh 965a688c97 fix(compiler-cli): use ModuleWithProviders type if static eval fails (#37126)
When the compiler encounters a function call within an NgModule imports
section, it attempts to resolve it to an NgModule-annotated class by
looking at the function body and evaluating the statements there. This
evaluation can only understand simple functions which have a single
return statement as their body. If the function the user writes is more
complex than that, the compiler won't be able to understand it and
previously the PartialEvaluator would return a "DynamicValue" for
that import.

With this change, in the event the function body resolution fails the
PartialEvaluator will now attempt to use its foreign function resolvers to
determine the correct result from the function's type signtaure instead. If
the function is annotated with a correct ModuleWithProviders type, the
compiler will be able to understand the import without static analysis of
the function body.

crisbeto ab3f4c9fe1 fix(core): infinite loop if injectable using inheritance has a custom decorator (#37022)
If we detect that an injectable class is inheriting from another injectable, we generate code that looks something like this:

```
const baseFactory = ɵɵgetInheritedFactory(Child);

@Injectable()
class Parent {}

@Injectable()
class Child extends Parent {
  static ɵfac = (t) => baseFactory(t || Child)
}
```

This usually works fine, because the `ɵɵgetInheritedFactory` resolves to the factory of `Parent`, but the logic can break down if the `Child` class has a custom decorator. Custom decorators can return a new class that extends the original once, which means that the `ɵɵgetInheritedFactory` call will now resolve to the factory of the `Child`, causing an infinite loop.

These changes fix the issue by changing the inherited factory resolution logic so that it walks up the prototype chain class-by-class, while skipping classes that have the same factory as the class that was passed in.

Fixes #35733.

Igor Minar a1001f2ea0 fix(core): disable tsickle pass when producing APF packages (#37221)
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.

George Kalpakas 89b44d1900 fix(elements): do not break when the constructor of an Angular Element is not called (#36114)
Previously, the correct behavior of Angular custom elements relied on
the constructor being called (and thus the `injector` property being
initialized). However, some polyfills (e.g. `document-register-element`)
do not call the constructor of custom elements, which resulted in the
`injector` property being undefined and the `NgElementStrategy` failing
to be instantiated.

This commit fixes it by being tolerant to the `injector` property being
undefined and falling back to the injector passed to the
`createCustomElement()` config.

NOTE:
We don't have proper tests exercising the situation where the
constructor is not called. For now this is tested using a Google
internal test suite (which is how this issue was caught).
This commit also adds a rudimentary unit test to emulate this situation.

George Kalpakas 2fc5ae561b fix(elements): capture input properties set before upgrading the element (#36114)
Previously, if an element started out as a regular `HTMLElement` (not a
Custom Element) and was later upgraded to a Custom Element, any
properties corresponding to component inputs that were set on the
element before upgrading it would not be captured correctly and thus not
reflected on the instantiated component.

This commit fixes it by ensuring that such properties are captured
correctly.

George Kalpakas cb719ee16e test(elements): clean up `TestStrategy` between tests (#36114)
Previously, the `TestStrategy` `NgElementStrategy` used in
`createCustomElement()` tests was created once and re-used in each test
(due to complications related to how `customElements.register()` works).
As a result, the `TestStrategy` instance's state (e.g. inputs) could be
polluted from previous tests and affect subsequent ones.

George Kalpakas 327980bf49 fix(elements): correctly handle getting/setting properties before connecting the element (#36114)
`createCustomElements()` creates some getters/setters for properties
corresponding to component inputs that delegate to the
`NgElementStrategy`. However, it is not guaranteed that the element's
`NgElementStrategy` will have been created when these getters/setters
are called, because some polyfills (e.g. `document-register-element`) do
not call the constructor.

Previously, trying to get/set input properties before connecting the
element to the DOM (via `connectedCallback()`) would fail due to
`NgElementStrategy` not being created.

This commit ensures that the `NgElementStrategy` is always created
before used inside the input property getters/setters (similar to how it
is done for other methods of `NgElement`).

Pete Bacon Darwin 3dfc7703c2 fix(compiler-cli): ensure LogicalFileSystem maintains case in paths (#37008)
The work to support case-sensitivity in the `FileSystem` went too far
with the `LogicalFileSystem`, which is used to compute import paths
that will be added to files processed by ngtsc and ngcc.

Previously all logical paths were canonicalised, which meant that on
case-insensitive file-systems, the paths were all set to lower case.
This resulted in incorrect imports being added to files. For example:

```
import { Apollo } from './Apollo';
import { SelectPipe } from './SelectPipe';
import * as ɵngcc0 from '@angular/core';
import * as ɵngcc1 from './selectpipe';
```

The import from `./SelectPipe` is from the original file, while the
import from `./selectpipe` is added by ngcc. This causes the
TypeScript compiler to complain, or worse for paths not to be
matched correctly.

Now, when computing logical paths, the original absolute paths
are matched against rootDirs in a canonical manner, but the actual
logical path that is returned maintains it original casing.

Daniel Seibel Silva ea971f7098 fix(core): inheritance delegate ctor regex updated to work on minified code (#36962)
If one component Parent inherit another component Base like the following:

@Component(...)
class Base {
  constructor(@Inject(InjectionToken) injector: Injector) { }
}

@Component(...)
class Parent extends Base {
    // no constructor
}

When creating Component Parent, the dependency injection should work on delegating ctors like above.

The code Parent code above will be compiled into something like:

class Parent extends Base {
  constructor() {
    super(...arguments);
  }
}

The angular core isDelegateCtor function will identify the delegation ctor to the base class.

But when the code above is minified (using terser), the minified code will compress the spaces, resulting in something like:
class Parent extends Base{constructor(){super(...arguments)}}

The regex will stop working, since it wasn't aware of this case. So this fix will allow this to work in minified code cases.

This is a workaround for a TS 3.9 regression https://github.com/microsoft/TypeScript/issues/38501 where the emitted `__exportStar` helpers have a missing semi-colon at the end of the unnamed function, when targetting UMD, and causes the following runtime error `Uncaught TypeError: (intermediate value)(…) is not a function`.

This is because the anonymous `__exportStar` function will be invoked with the function on the next like as the parameter which is subsequently invoking whatever was returned.

To get around this TS bug, add `importHelpers: true` in your tsconfig. This also, is recommanded to avoid multiple copies of the same helper being inlined, which might cause increase in bundle size.

In some versions of TypeScript, the transformation of synthetic

We now compute what the expected final output target of the

for us.

This is a workaround for the TS compiler bug, which could be removed

Keen Yee Liau 40025f55ad refactor(language-service): move TS utils to separate file (#36984)
This commit refactors TS-only utility functions to a separate file so
that they could be shared with Ivy language service.
A separate ts_library rule is created so that there is no dependency on
`compiler` and `compiler-cli` to make the compilation fast and
light-weight.
The method `getPropertyAssignmentFromValue` is modified slightly to
improve the ergonomics of the function.

Ayaz Hafiz eb34aa551a feat(compiler): add name spans for property reads and method calls (#36826)
ASTs for property read and method calls contain information about
the entire span of the expression, including its receiver. Use cases
like a language service and compile error messages may be more
interested in the span of the direct identifier for which the
expression is constructed (i.e. an accessed property). To support this,
this commit adds a `nameSpan` property on

- `PropertyRead`s
- `SafePropertyRead`s
- `PropertyWrite`s
- `MethodCall`s
- `SafeMethodCall`s

The `nameSpan` property already existed for `BindingPipe`s.

This commit also updates usages of these expressions' `sourceSpan`s in
Ngtsc and the langauge service to use `nameSpan`s where appropriate.

Paul Gschwendtner d0280a0335 fix(compiler): remove outdated and invalid warning for unresolved DI parameters (#36985)
In past versions of the View Engine compiler, we added a warning that is
printed whenever the compiler comes across an Angular declaration with a
constructor that does not match suitable DI tokens. The warning mentioned
that in `v6.x` it will turn into an actual error.

This actually happened as expected for most cases. e.g. the constructor
of `@NgModule`, `@Component`'s, `@Pipe`'s etc will be checked and an error
will be reported if constructor is not DI compatible.

The warning has never been removed though as it was still relevant for
unprovided injectables, or injectables serialized into summaries of the
Angular compiler.

As of version 10, classes that use Angular features need an Angular decorator.
This includes base classes of services that use the lifecycles Angular feature.
Due to this being a common pattern now, we can remove the warning in
View Engine. The warning is not correct, and also quite confusing as it
mentions the planned removal in `v6.x`.

Tidi 97d6d909e7 fix(forms): number input fires valueChanges twice. (#36087)
Prior to this commit, number input fields would to fire valueChanges twice: once for `input` events when typing and second for the `change` event when the field lost focus (both events happen at once when using the increment and decrement buttons on the number field).

Fixes #12540

BREAKING CHANGE: Number inputs no longer listen to the `change` event.
* Tests which trigger `change` events need to be updated to trigger `input` events instead.
* The `change` event was in place to support IE9, as we found that `input` events were not fired with backspace or cut actions. If you need to maintain IE9 support, you will need to add a change event listener to number inputs and call the `onChange` method of `NumberValueAccessor` manually.
* Lastly, old versions of WebDriver would synthetically trigger the `change` event on `WebElement.clear` and `WebElement.sendKeys`. If you are using an old version of WebDriver, you may need to update tests to ensure `input` events are triggered. For example, you could use `element.sendKeys(Keys.chord(Keys.CONTROL, "a"), Keys.BACK_SPACE);` in place of `element.clear()`.

Paul Gschwendtner 0577bf0e3e refactor: enable ng update migrations for v10 (#36921)
Enables the `ng update` migrations for v10. Status for individual
migrations:

**undecorated-classes-with-di**.

This migration dealt exlusively with inherited constructors and
cases where a derived component was undecorated. In those cases,
the migration added `@Directive()` or copied the inherited decorator
to the derived class.

We don't need to run this migration again because ngtsc throws if
constructor is inherited from an undecorated class. Also ngtsc will
throw if a NgModule references an undecorated class in the declarations.

***undecorated-classes-with-decorated-fields***

This migration exclusively deals with undecorated classes that use
Angular features but are not decorated. Angular features include
the use of lifecycle hooks or class fields with Angular decorators,
such as `@Input()`.

We want to re-run this migration in v10 as we will disable the
compatibility code in ngtsc that detects such undecorated classes
as `@Directive`.

**module-with-providers**:

This migration adds an explicit generic type to `ModuleWithProviders`.
As of v10, the generic type is required, so we need to re-run the
migration again.

**renderer-to-renderer2**:

We don't need to re-run that migration again as the
renderer has been already removed in v9.

**missing-injectable**:

This migration is exclusively concerned with undecorated
providers referenced in an `NgModule`. We should re-run
that migration again as we don't have proper backsliding
prevention for this yet. We can consider adding an error
in ngtsc for v10, or v11. In either way, we should re-run
the migration.

**dynamic-queries**:

We ran this one in v9 to reduce code complexity in projects. Instead
of explicitly passing `static: false`, not passing any object literal
has the same semantics. We don't need to re-run the migration again
since there is no good way to prevent backsliding and we cannot always
run this migration for future versions (as some apps might actually
intentionally use the explicit `static: false` option).

Paul Gschwendtner c6ecdc9a81 feat(core): undecorated-classes-with-decorated-fields migration should handle classes with lifecycle hooks (#36921)
As of v10, undecorated classes using Angular features are no longer
supported. In v10, we plan on removing the undecorated classes
compatibility code in ngtsc. This means that old patterns for
undecorated classes will result in compilation errors.

We had a migration for this in v9 already, but it looks like
the migration does not handle cases where classes uses lifecycle
hooks. This is handled in the ngtsc compatibility code, and we
should handle it similarly in migrations too.

This has not been outlined in the migration plan initially,
but an appendix has been added for v10 to the plan document.

https://hackmd.io/vuQfavzfRG6KUCtU7oK_EA?both.

Note: The migration is unable to determine whether a given undecorated
class that only defines `ngOnDestroy` is a directive or an actual
service. This means that in some cases the migration cannot do
more than adding a TODO and printing an failure.

Certainly there are more ways to determine the type of such classes,
but it would involve metadata and NgModule analysis. This is out of
scope for this migration.

We currently achieve this by checking the path the `module`
property points to. We can do this because as per APF, the

more coverage, we want to sniff the format by looking for

Paul Gschwendtner d5293d2aa3 fix(bazel): ng_package rule should update "package.json" of ts_library targets (#36944)
In the past we added support for `ts_library` to `ng_package`. For those
targets we never can determine the "index" file. Unlike `ng_module`,
there is no provider data for flat module bundles, so the `ng_package`
rule assumes that the index file is simply called `index`.

This works as expected, but we also added logic in the past that doesn't
allow `ng_package` to add format properties (e.g. `main`, `module`) to a
`package.json` if a package json is handwritten for such a `ts_library` target.

This has been done that way because we assumed that such `package.json` files
might want to set format properties explicitly to different paths due to a
faulty "index" guess.

We want to change this behavior as most of the time a `package.json`
file already exists with just the module name. In those cases, the
packager should still set the format properties. We should only warn
and skip automatic insertion of the format properties if such a
`package.json` explicitly sets format properties.

This commit intentionally doesn't fully clean up the ng_package rule to remove all traces of esm5 and fems5

BREAKING CHANGE: esm5 and fesm5 format is no longer distributed in
Angular's npm packages e.g. @angular/core

If you are not using Angular CLI to build your application or library,
and you need to be able to build es5 artifacts, then you will need to
downlevel the distributed Angular code to es5 on your own.

Angular CLI will automatically downlevel the code to es5 if differential
loading is enabled in the Angular project, so no action is required from

Alex Rickabaugh ecffc3557f perf(compiler-cli): perform template type-checking incrementally (#36211)
This optimization builds on a lot of prior work to finally make type-
checking of templates incremental.

Incrementality requires two main components:
- the ability to reuse work from a prior compilation.
- the ability to know when changes in the current program invalidate that
  prior work.

Prior to this commit, on every type-checking pass the compiler would
generate new .ngtypecheck files for each original input file in the program.

1. (Build #1 main program): empty .ngtypecheck files generated for each
   original input file.

2. (Build #1 type-check program): .ngtypecheck contents overridden for those
   which have corresponding components that need type-checked.

3. (Build #2 main program): throw away old .ngtypecheck files and generate
   new empty ones.

4. (Build #2 type-check program): same as step 2.

With this commit, the `IncrementalDriver` now tracks template type-checking
_metadata_ for each input file. The metadata contains information about
source mappings for generated type-checking code, as well as some
diagnostics which were discovered at type-check analysis time. The actual
type-checking code is stored in the TypeScript AST for type-checking files,
which is now re-used between programs as follows:

1. (Build #1 main program): empty .ngtypecheck files generated for each
   original input file.

2. (Build #1 type-check program): .ngtypecheck contents overridden for those
   which have corresponding components that need type-checked, and the
   metadata registered in the `IncrementalDriver`.

3. (Build #2 main program): The `TypeCheckShimGenerator` now reuses _all_
   .ngtypecheck `ts.SourceFile` shims from build #1's type-check program in
   the construction of build #2's main program. Some of the contents of
   these files might be stale (if a component's template changed, for
   example), but wholesale reuse here prevents unnecessary changes in the
   contents of the program at this point and makes TypeScript's job a lot
   easier.

4. (Build #2 type-check program): For those input files which have not
   "logically changed" (meaning components within are semantically the same
   as they were before), the compiler will re-use the type-check file
   metadata from build #1, and _not_ generate a new .ngtypecheck shim.
   For components which have logically changed or where the previous
   .ngtypecheck contents cannot otherwise be reused, code generation happens
   as before.

Alex Rickabaugh b861e9c0ac perf(compiler-cli): split Ivy template type-checking into multiple files (#36211)
As a performance optimization, this commit splits the single
__ngtypecheck__.ts file which was previously added to the user's program as
a container for all template type-checking code into multiple .ngtypecheck
shim files, one for each original file in the user's program.

In larger applications, the generation, parsing, and checking of this single
type-checking file was a huge performance bottleneck, with the file often
exceeding 1 MB in text content. Particularly in incremental builds,
regenerating this single file for the entire application proved especially
expensive.

This commit introduces a new strategy for template type-checking code which
makes use of a new interface, the `TypeCheckingProgramStrategy`. This
interface abstracts the process of creating a new `ts.Program` to type-check
a particular compilation, and allows the mechanism there to be kept separate
from the more complex logic around dealing with multiple .ngtypecheck files.

A new `TemplateTypeChecker` hosts that logic and interacts with the
`TypeCheckingProgramStrategy` to actually generate and return diagnostics.
The `TypeCheckContext` class, previously the workhorse of template type-
checking, is now solely focused on collecting and generating type-checking
file contents.

A side effect of implementing the new `TypeCheckingProgramStrategy` in this
way is that the API is designed to be suitable for use by the Angular
Language Service as well. The LS also needs to type-check components, but
has its own method for constructing a `ts.Program` with type-checking code.

Note that this commit does not make the actual checking of templates at all
_incremental_ just yet. That will happen in a future commit.

Alex Rickabaugh 4213e8d5f0 fix(compiler): switch to 'referencedFiles' for shim generation (#36211)
Shim generation was built on a lie.

Shims are files added to the program which aren't original files authored by
the user, but files authored effectively by the compiler. These fall into
two categories: files which will be generated (like the .ngfactory shims we
generate for View Engine compatibility) as well as files used internally in
compilation (like the __ng_typecheck__.ts file).

Previously, shim generation was driven by the `rootFiles` passed to the
compiler as input. These are effectively the `files` listed in the
`tsconfig.json`. Each shim generator (e.g. the `FactoryGenerator`) would
examine the `rootFiles` and produce a list of shim file names which it would
be responsible for generating. These names would then be added to the
`rootFiles` when the program was created.

The fatal flaw here is that `rootFiles` does not always account for all of
the files in the program. In fact, it's quite rare that it does. Users don't
typically specify every file directly in `files`. Instead, they rely on
TypeScript, during program creation, starting with a few root files and
transitively discovering all of the files in the program.

This happens, however, during `ts.createProgram`, which is too late to add
new files to the `rootFiles` list.

As a result, shim generation was only including shims for files actually
listed in the `tsconfig.json` file, and not for the transitive set of files
in the user's program as it should.

This commit completely rewrites shim generation to use a different technique
for adding files to the program, inspired by View Engine's shim generator.
In this new technique, as the program is being created and `ts.SourceFile`s
are being requested from the `NgCompilerHost`, shims for those files are
generated and a reference to them is patched onto the original file's
`ts.SourceFile.referencedFiles`. This causes TS to think that the original
file references the shim, and causes the shim to be included in the program.
The original `referencedFiles` array is saved and restored after program
creation, hiding this little hack from the rest of the system.

The new shim generation engine differentiates between two kinds of shims:
top-level shims (such as the flat module entrypoint file and
__ng_typecheck__.ts) and per-file shims such as ngfactory or ngsummary
files. The former are included via `rootFiles` as before, the latter are
included via the `referencedFiles` of their corresponding original files.

As a result of this change, shims are now correctly generated for all files
in the program, not just the ones named in `tsconfig.json`.

A few mitigating factors prevented this bug from being realized until now:

* in g3, `files` does include the transitive closure of files in the program
* in CLI apps, shims are not really used

This change also makes use of a novel technique for associating information
with source files: the use of an `NgExtension` `Symbol` to patch the
information directly onto the AST object. This is used in several
circumstances:

* For shims, metadata about a `ts.SourceFile`'s status as a shim and its
  origins are held in the extension data.
* For original files, the original `referencedFiles` are stashed in the
  extension data for later restoration.

The main benefit of this technique is a lot less bookkeeping around `Map`s
of `ts.SourceFile`s to various kinds of data, which need to be tracked/
invalidated as part of incremental builds.

This technique is based on designs used internally in the TypeScript
compiler and is serving as a prototype of this design in ngtsc. If it works
well, it could have benefits across the rest of the compiler.

Alex Rickabaugh bab90a7709 fix(compiler-cli): fix bug tracking indirect NgModule dependencies (#36211)
The compiler needs to track the dependencies of a component, including any
NgModules which happen to be present in a component's scope. If an upstream
NgModule changes, any downstream components need to have their templates
re-compiled and re-typechecked.

Previously, the compiler handled this well for the A -> B -> C case where
module A imports module B which re-exports module C. However, it fell apart
in the A -> B -> C -> D case, because previously tracking focused on changes
to components/directives in the scope, and not NgModules specifically.

This commit introduces logic to track which NgModules contributed to a given
scope, and treat them as dependencies of any components within.

This logic also contains a bug, which is intentional for now. It
purposefully does not track transitive dependencies of the NgModules which
contribute to a scope. If it did, using the current dependency system, this
would treat all components and directives (even those not exported into the
scope) as dependencies, causing a major performance bottleneck. Only those
dependencies which contributed to the module's export scope should be
considered, but the current system is incapable of making this distinction.
This will be fixed at a later date.

Keen Yee Liau da79e0433f test(language-service): [ivy] Add mock service to overwrite files (#36923)
Add a mechanism to replace file contents for a specific file. This
allows us to write custom test scenarios in code without modifying the
test project.

Since we are no longer mocking the language service host, the file
overwrite needs to happen via the project service.
Project service manages a set of script infos, and overwriting the files
is a matter of updating the relevant script infos.

Note that the actual project service is wrapped inside a Mock Service.
Tests should not have direct access to the project service. All
manipulations should take place via the Mock Service.

This commit adds a new mock host for testing the ivy language service.

Unlike the existing mock_host which mocks the LanguageServiceHost, the
Ivy mock host mocks just the filesystem interface, aka ts.ServerHost.

This is because Ivy language service requires an actual Project to
perform operations like adding synthetic typecheck files to the project,
and by extension, to the ts.Program. These requirements make the existing
mock host unsuitable to be reused.

This new testing structure also improves test performance, because the
old mock host copies (it actually creates symlinks, but still that's
relatively expensive due to the sheer number of files involved) all
@angular/* packages along with the typescript package to a temporary
node_modules directory. This is done every time setup() is called.

Maximilian Koeller ee35e223a7 feat(service-worker): use `ignoreVary: true` when retrieving responses from cache (#34663)
The Angular ServiceWorker always uses a copy of the request without
headers for caching assets (in order to avoid issues with opaque
responses). Therefore, it was previously not possible to retrieve
resources from the cache if the response contained [Vary](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Vary) headers.

In addition to that, `Vary` headers do not work in all browsers (or work
differently) and may not work as intended with ServiceWorker caches. See
[this article](https://www.smashingmagazine.com/2017/11/understanding-vary-header) and the linked resources for more info.

This commit avoids the aforementioned issues by making sure the Angular
ServiceWorker always sets the `ignoreVary` option passed to
[Cache#match()](https://developer.mozilla.org/en-US/docs/Web/API/Cache/match) to `true`. This allows the ServiceWorker to correctly
retrieve cached responses with `Vary` headers, which was previously not
possible.

Fixes #36638

BREAKING CHANGE:

Previously, [Vary](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Vary)
headers would be taken into account when retrieving resources from the
cache, completely preventing the retrieval of cached assets (due to
ServiceWorker implementation details) and leading to unpredictable
behavior due to inconsistent/buggy implementations in different
browsers.

Now, `Vary` headers are ignored when retrieving resources from the
ServiceWorker caches, which can result in resources being retrieved even
when their headers are different. If your application needs to
differentiate its responses based on request headers, please make sure
the Angular ServiceWorker is [configured](https://angular.io/guide/service-worker-config)

George Kalpakas 4779c4b94a fix(ngcc): handle `ENOMEM` errors in worker processes (#36626)
When running in parallel mode, worker processes forward errors thrown
during task processing to the master process, which in turn exits with
an error.

However, there are cases where the error is not directly related to
processing the entry-point. One such case is when there is not enough
memory (for example, due to all the other tasks being processed
simultaneously).

Previously, an `ENOMEM` error thrown on a worker process would propagate
to the master process, eventually causing ngcc to exit with an error.
Example failure: https://circleci.com/gh/angular/angular/682198

This commit improves handling of these low-memory situations by
detecting `ENOMEM` errors and killing the worker process, thus allowing
the master process to decide how to handle that. The master process will
put the task back into the tasks queue and continue processing tasks
with the rest of the worker processes (and thus with lower memory
pressure).

George Kalpakas 966598cda7 fix(ngcc): support recovering when a worker process crashes (#36626)
Previously, when running in parallel mode and a worker process crashed
while processing a task, it was not possible for ngcc to continue
without risking ending up with a corrupted entry-point and therefore it
exited with an error. This, for example, could happen when a worker
process received a `SIGKILL` signal, which was frequently observed in CI
environments. This was probably the result of Docker killing processes
due to increased memory pressure.

One factor that amplifies the problem under Docker (which is often used
in CI) is that it is not possible to distinguish between the available
CPU cores on the host machine and the ones made available to Docker
containers, thus resulting in ngcc spawning too many worker processes.

This commit addresses these issues in the following ways:

1. We take advantage of the fact that files are written to disk only
   after an entry-point has been fully analyzed/compiled. The master
   process can now determine whether a worker process has not yet
   started writing files to disk (even if it was in the middle of
   processing a task) and just put the task back into the tasks queue if
   the worker process crashes.

2. The master process keeps track of the transformed files that a worker
   process will attempt to write to disk. If the worker process crashes
   while writing files, the master process can revert any changes and
   put the task back into the tasks queue (without risking corruption).

3. When a worker process crashes while processing a task (which can be a
   result of increased memory pressure or too many worker processes),
   the master process will not try to re-spawn it. This way the number
   or worker processes is gradually adjusted to a level that can be
   accomodated by the system's resources.

Examples of ngcc being able to recover after a worker process crashed:
- While idling: https://circleci.com/gh/angular/angular/682197
- While compiling: https://circleci.com/gh/angular/angular/682209

George Kalpakas 4c63241b34 fix(ngcc): do not run in parallel mode if there are less than 3 CPU cores (#36626)
Previously, ngcc would run in parallel mode (using the
`ClusterExecutor`) when there were at least 2 CPU cores (and all other
requirements where met). On systems with just 2 CPU cores, this meant
there would only be one worker process (since one CPU core is always
reserved for the master process). In these cases, the tasks would still
be processed serially (on the one worker process), but we would also pay
the overhead of communicating between the master and worker processes.

This commit fixes this by only running in parallel mode if there are
more than 2 CPU cores (i.e. at least 2 worker processes).

JoostK 89c589085d fix(ngcc): recognize enum declarations emitted in JavaScript (#36550)
An enum declaration in TypeScript code will be emitted into JavaScript
as a regular variable declaration, with the enum members being declared
inside an IIFE. For ngcc to support interpreting such variable
declarations as enum declarations with its members, ngcc needs to
recognize the enum declaration emit structure and extract all member
from the statements in the IIFE.

This commit extends the `ConcreteDeclaration` structure in the
`ReflectionHost` abstraction to be able to capture the enum members
on a variable declaration, as a substitute for the original
`ts.EnumDeclaration` as it existed in TypeScript code. The static
interpreter has been extended to handle the extracted enum members
as it would have done for `ts.EnumDeclaration`.

Pete Bacon Darwin 70dd27ffd8 fix(compiler): normalize line endings in ICU expansions (#36741)
The html parser already normalizes line endings (converting `\r\n` to `\n`)
for most text in templates but it was missing the expressions of ICU expansions.

In ViewEngine backticked literal strings, used to define inline templates,
were already normalized by the TypeScript parser.
In Ivy we are parsing the raw text of the source file directly so the line
endings need to be manually normalized.

This change ensures that inline templates have the line endings of ICU
expression normalized correctly, which matches the ViewEngine.

In ViewEngine external templates, defined in HTML files, the behavior was
different, since TypeScript was not normalizing the line endings.
Specifically, ICU expansion "expressions" are not being normalized.
This is a problem because it means that i18n message ids can be different on
different machines that are setup with different line ending handling,
or if the developer moves a template from inline to external or vice versa.

The goal is always to normalize line endings, whether inline or external.
But this would be a breaking change since it would change i18n message ids
that have been previously computed. Therefore this commit aligns the ivy
template parsing to have the same "buggy" behavior for external templates.

There is now a compiler option `i18nNormalizeLineEndingsInICUs`, which
if set to `true` will ensure the correct non-buggy behavior. For the time
being this option defaults to `false` to ensure backward compatibility while
allowing opt-in to the desired behavior. This option's default will be
flipped in a future breaking change release.

Further, when this option is set to `false`, any ICU expression tokens,
which have not been normalized, are added to the `ParseResult` from the
`HtmlParser.parse()` method. In the future, this collection of tokens could
be used to diagnose and encourage developers to migrate their i18n message
ids. See FW-2106.

Pete Bacon Darwin 0c2ed4c3e5 fix(ngcc): do not use cached file-system (#36687)
The cached file-system was implemented to speed up ngcc
processing, but in reality most files are not accessed many times
and there is no noticeable degradation in speed by removing it.

Benchmarking `ngcc -l debug` for AIO on a local machine
gave a range of 196-236 seconds with the cache and 197-224
seconds without the cache.

Moreover, when running in parallel mode, ngcc has a separate
file cache for each process. This results in excess memory usage.
Notably the master process, which only does analysis of entry-points
holds on to up to 500Mb for AIO when using the cache compared to
only around 30Mb when not using the cache.

Finally, the file-system cache being incorrectly primed with file
contents before being processed has been the cause of a number
of bugs. For example https://github.com/angular/angular-cli/issues/16860#issuecomment-614694269.

George Kalpakas 66effde9f3 fix(ngcc): do not spawn unlocker processes on cluster workers (#36569)
The current ngcc lock-file strategy spawns a new process in order to
capture a potential `SIGINT` and remove the lock-file. For more
information see #35861.

Previously, this unlocker process was spawned as soon as the `LockFile`
was instantiated in order to have it available as soon as possible
(given that spawning a process is an asynchronous operation). Since the
`LockFile` was instantiated and passed to the `Executor`, this meant
that an unlocker process was spawned for each cluster worker, when
running ngcc in parallel mode. These processes were not needed, since
the `LockFile` was not used in cluster workers, but we still had to pay
the overhead of each process' own memory and V8 instance.
(NOTE: This overhead was small compared to the memory consumed by ngcc's
normal operations, but still unnecessary.)

This commit avoids the extra processes by only spawning an unlocker
process when running on the cluster master process and not on worker
processes.
