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.

Alex Rickabaugh 5103d908c8 perf(compiler-cli): fix regressions in incremental program reuse (#37641)
Commit 4213e8d5 introduced shim reference tagging into the compiler, and
changed how the `TypeCheckProgramHost` worked under the hood during the
creation of a template type-checking program. This work enabled a more
incremental flow for template type-checking, but unintentionally introduced
several regressions in performance, caused by poor incrementality during
`ts.Program` creation.

1. The `TypeCheckProgramHost` was made to rely on the `ts.CompilerHost` to
   retrieve instances of `ts.SourceFile`s from the original program. If the
   host does not return the original instance of such files, but instead
   creates new instances, this has two negative effects: it incurs
   additional parsing time, and it interferes with TypeScript's ability to
   reuse information about such files.

2. During the incremental creation of a `ts.Program`, TypeScript compares
   the `referencedFiles` of `ts.SourceFile` instances from the old program
   with those in the new program. If these arrays differ, TypeScript cannot
   fully reuse the old program. The implementation of reference tagging
   introduced in 4213e8d5 restores the original `referencedFiles` array
   after a `ts.Program` is created, which means that future incremental
   operations involving that program will always fail this comparison,
   effectively limiting the incrementality TypeScript can achieve.

Problem 1 exacerbates problem 2: if a new `ts.SourceFile` is created by the
host after shim generation has been disabled, it will have an untagged
`referencedFiles` array even if the original file's `referencedFiles` was
not restored, triggering problem 2 when creating the template type-checking
program.

To fix these issues, `referencedFiles` arrays are now restored on the old
`ts.Program` prior to the creation of a new incremental program. This allows
TypeScript to get the most out of reusing the old program's data.

Additionally, the `TypeCheckProgramHost` now uses the original `ts.Program`
to retrieve original instances of `ts.SourceFile`s where possible,
preventing issues when a host would otherwise return fresh instances.

Together, these fixes ensure that program reuse is as incremental as
possible, and tests have been added to verify this for certain scenarios.

An optimization was further added to prevent the creation of a type-checking
`ts.Program` in the first place if no type-checking is necessary.

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.

Pete Bacon Darwin 07a07e34bc fix(compiler-cli): only read source-map comment from last line (#32912)
Source-maps can be linked to from a source-file by a comment at
the end of the file.

Previously the `SourceFileLoader` would read
the first comment that matched `//# sourceMappingURL=` but
this is not valid since some bundlers may include embedded
source-files that contain such a comment.

Now we only look for this comment in the last non-empty line
in the file.

Pete Bacon Darwin decd95e7f0 fix(compiler-cli): ensure source-maps can handle webpack:// protocol (#32912)
Webpack and other build tools sometimes inline the contents of the
source files in their generated source-maps, and at the same time
change the paths to be prefixed with a protocol, such as `webpack://`.

This can confuse tools that need to read these paths, so now it is
possible to provide a mapping to where these files originated.
