Andrew Kushnir 856db56cca refactor(forms): get rid of duplicate functions (#38371)
This commit performs minor refactoring in Forms package to get rid of duplicate functions.
It looks like the functions were duplicated due to a slightly different type signatures, but
their logic is completely identical. The logic in retained functions remains the same and now
these function also accept a generic type to achieve the same level of type safety.

Sonu Kapoor df7f3b04b5 fix(service-worker): fix the chrome debugger syntax highlighter (#38332)
The Chrome debugger is not able to render the syntax properly when the
code contains backticks. This is a known issue in Chrome and they have an
open [issue](https://bugs.chromium.org/p/chromium/issues/detail?id=659515) for that.
This commit adds the work-around to use double backslash with one
backtick ``\\` `` at the end of the line.

This can be reproduced by running the following command:

`yarn bazel test //packages/forms/test --config=debug`

When opening the chrome debugger tools, you should see the correct

JoostK 7525f3afc1 fix(compiler-cli): type-check inputs that include undefined when there's coercion members (#38273)
For attribute bindings that target a directive's input, the template
type checker is able to verify that the type of the input expression is
compatible with the directive's declaration for said input. This
checking adheres to the `strictNullChecks` flag as configured in the
TypeScript compilation, such that errors are reported for expressions
that include `undefined` or `null` in their type if the input's
declaration does not include those types.

There was a bug with this level of type-checking for directives that
also declare coercion members, where binding an expression that includes
the `undefined` type to a directive's input that does not include the
`undefined` type would not be reported as error.

This commit fixes the bug by changing the type-constructor in type-check
code to use an intersection type of regular inputs and coerced inputs,
instead of a union type. The union type would inadvertently allow
`undefined` types to be assigned into the regular inputs, as that would
still satisfy the characteristics of a union type.

As a result of this change, you may start to see build failures if
`strictTemplates` is enabled and `strictInputTypes` is not disabled.
These errors are legitimate and some action is required to achieve a
successful build:

1. Update the templates for which an error is reported and introduce the
   non-null assertion operator at the end of the expression. This
   removes the `undefined` type from the expression's type, making it
   appear as a valid assignment.
2. Disable `strictNullInputTypes` in the compiler options. This will
   implicitly add the non-null assertion operators similar to option 1,
   but all templates in the compilation are affected.
3. Update the directive's input declaration to include the `undefined`
   type, if the directive is not implemented in an external library.

Doug Parker dca4443a8e fix(compiler-cli): mark eager `NgModuleFactory` construction as not side effectful (#38320)
Roll forward of #38147.

This allows Closure compiler to tree shake unused constructor calls to `NgModuleFactory`, which is otherwise considered
side-effectful. The Angular compiler generates factory objects which are exported but typically not used, as they are
only needed for compatibility with View Engine. This results in top-level constructor calls, such as:

```typescript
export const FooNgFactory = new NgModuleFactory(Foo);
```

`NgModuleFactory` has a side-effecting constructor, so this statement cannot be tree shaken, even if `FooNgFactory` is
never imported. The `NgModuleFactory` continues to reference its associated `NgModule` and prevents the module and all
its unused dependencies from being tree shaken, making Closure builds significantly larger than necessary.

The fix here is to wrap `NgModuleFactory` constructor with `noSideEffects(() => /* ... */)`, which tricks the Closure
compiler into assuming that the invoked function has no side effects. This allows it to tree-shake unused
`NgModuleFactory()` constructors when they aren't imported. Since the factory can be removed, the module can also be
removed (if nothing else references it), thus tree shaking unused dependencies as expected.

The one notable edge case is for lazy loaded modules. Internally, lazy loading is done as a side effect when the lazy
script is evaluated. For Angular, this side effect is registering the `NgModule`. In Ivy this is done by the
`NgModuleFactory` constructor, so lazy loaded modules **cannot** have their top-level `NgModuleFactory` constructor
call tree shaken. We handle this case by looking for the `id` field on `@NgModule` annotations. All lazy loaded modules
include an `id`. When this `id` is found, the `NgModuleFactory` is generated **without** with `noSideEffects()` call,
so Closure will not tree shake it and the module will lazy-load correctly.

Joey Perrott ff9f4de4f1 fix(compiler): update unparsable character reference entity error messages (#38319)
Within an angular template, when a character entity is unable to be parsed, previously a generic
unexpected character error was thrown.  This does not properly express the issue that was discovered

The compiler will now instead inform via the error message what string was attempted to be parsed

Example, for this template:
```
<p>
  &#x123p
</p>
```

Retrieving `ts.Program` at startup will trigger an `updateGraph` operation,

Keen Yee Liau fd51e01335 fix(compiler): Metadata should not include methods on Object.prototype (#38292)
This commit fixes a bug in View Engine whereby the compiler errorneously
thinks that a method of a component has decorator metadata when that
method is one of those in `Object.prototype`, for example `toString`.

This bug is discovered in v10.0.4 of `@angular/language-service` after
the default bundle format was switched from ES5 to ES2015.

ES5 output:
```js
if (propMetadata[propName]) {
    decorators.push.apply(decorators, __spread(propMetadata[propName]));
}
```

ES2015 output:
```js
if (propMetadata[propName]) {
    decorators.push(...propMetadata[propName]);
}
```

The bug was not discovered in ES5 because the polyfill for the spread
operator happily accepts parameters that do not have the `iterable`
symbol:

```js
function __spread() {
    for (var ar = [], i = 0; i < arguments.length; i++)
        ar = ar.concat(__read(arguments[i]));
    return ar;
}
```

whereas in es2015 it’ll fail since the iterable symbol is not present in
`propMetadata['toString']` which evaluates to a function.

Doug Parker 887c350f9d refactor(compiler): wrap large strings in function (#38253)
Large strings constants are now wrapped in a function which is called whenever used. This works around a unique
limitation of Closure, where it will **always** inline string literals at **every** usage, regardless of how large the
string literal is or how many times it is used.The workaround is to use a function rather than a string literal.
Closure has differently inlining semantics for functions, where it will check the length of the function and the number
of times it is used before choosing to inline it. By using a function, `ngtsc` makes Closure more conservative about
inlining large strings, and avoids blowing up the bundle size.This optimization is only used if the constant is a large
string. A wrapping function is not included for other use cases, since it would just increase the bundle size and add
unnecessary runtime performance overhead.

Alex Rickabaugh c573d91285 refactor(compiler-cli): allow program strategies to opt out of inlining (#38105)
The template type-checking engine relies on the abstraction interface
`TypeCheckingProgramStrategy` to create updated `ts.Program`s for
template type-checking. The basic API is that the type-checking engine
requests changes to certain files in the program, and the strategy provides
an updated `ts.Program`.

Typically, such changes are made to 'ngtypecheck' shim files, but certain
conditions can cause template type-checking to require "inline" operations,
which change user .ts files instead. The strategy used by 'ngc' (the
`ReusedProgramStrategy`) supports these kinds of updates, but other clients
such as the language service might not always support modifying user files.

To accommodate this, the `TypeCheckingProgramStrategy` interface was
modified to include a `supportsInlineOperations` flag. If an implementation
specifies `false` for inline support, the template type-checking system will
return diagnostics on components which would otherwise require inline
operations.

* the `TemplateTypeChecker` interface supports diagnostics on a whole
  program basis to start with, but the implementation is purposefully
  designed to support incremental diagnostics at a per-file or per-component
  level.
* `TemplateTypeChecker` supports direct access to the type check block of a
  component.

Alex Rickabaugh 736f6337b2 refactor(compiler-cli): make file/shim split 1:n instead of 1:1 (#38105)
Previously in the template type-checking engine, it was assumed that every
input file would have an associated type-checking shim. The type check block
code for all components in the input file would be generated into this shim.

This is fine for whole-program type checking operations, but to support the
language service's requirements for low latency, it would be ideal to be
able to check a single component in isolation, especially if the component
is declared along with many others in a single file.

This commit removes the assumption that the file/shim mapping is 1:1, and
introduces the concept of component-to-shim mapping. Any
`TypeCheckingProgramStrategy` must provide such a mapping.

To achieve this:

 * type checking record information is now split into file-level data as
   well as per-shim data.
 * components are now assigned a stable `TemplateId` which is unique to the
   file in which they're declared.

Andrea Canciani 9c8bc4a239 fix(common): narrow `NgIf` context variables in template type checker (#36627)
When the `NgIf` directive is used in a template, its context variables
can be used to capture the bound value. This is sometimes used in
complex expressions, where the resulting value is captured in a
context variable. There's two syntax forms available:

1. Binding to `NgIfContext.ngIf` using the `as` syntax:
```html
<span *ngIf="enabled && user as u">{{u.name}}</span>
```

2. Binding to `NgIfContext.$implicit` using the `let` syntax:
```html
<span *ngIf="enabled && user; let u">{{u.name}}</span>
```

Because of the semantics of `ngIf`, it is known that the captured
context variable is truthy, however the template type checker
would not consider them as such and still report errors when
`strict` is enabled.

This commit updates `NgIf`'s context guard to make the types of the
context variables truthy, avoiding the issue.

Igor Minar 5d3ba8dec7 test: update ts-api-guardian's strip_export_pattern to exclude Ivy instructions (#38224)
Previously the instructions were included in the golden files to monitor the frequency and rate of
the instruction API changes for the purpose of understanding the stability of this API (as it was
considered for becoming a public API and deployed to npm via generated code).

This experiment has confirmed that the instruction API is not stable enough to be used as public
API. We've since also came up with an alternative plan to compile libraries with the Ivy compiler
for npm deployment and this plan does not rely on making Ivy instructions public.

For these reasons, I'm removing the instructions from the golden files as it's no longer important
to track them.

The are three instructions that are still being included: `ɵɵdefineInjectable`, `ɵɵinject`, and
`ɵɵInjectableDef`.

These instructions are already generated by the VE compiler to support tree-shakable providers, and
code depending on these instructions is already deployed to npm. For this reason we need to treat
them as public api.

This change also reduces the code review overhead, because changes to public api golden files now
require multiple approvals.

JoostK 1a7a7360b0 fix(compiler): properly associate source spans for implicitly closed elements (#38126)
HTML is very lenient when it comes to closing elements, so Angular's parser has
rules that specify which elements are implicitly closed when closing a tag.
The parser keeps track of the nesting of tag names using a stack and parsing
a closing tag will pop as many elements off the stack as possible, provided
that the elements can be implicitly closed.

For example, consider the following templates:

- `<div><br></div>`, the `<br>` is implicitly closed when parsing `</div>`,
  because `<br>` is a void element.
- `<div><p></div>`, the `<p>` is implicitly closed when parsing `</div>`,
  as `<p>` is allowed to be closed by the closing of its parent element.
- `<ul><li>A <li>B</ul>`, the first `<li>` is implicitly closed when parsing
  the second `<li>`, whereas the second `<li>` would be implicitly closed when
  parsing the `</ul>`.

In all the cases above the parsed structure would be correct, however the source
span of the closing `</div>` would incorrectly be assigned to the element that
is implicitly closed. The problem was that closing an element would associate
the source span with the element at the top of the stack, however this may not
be the element that is actually being closed if some elements would be
implicitly closed.

This commit fixes the issue by assigning the end source span with the element
on the stack that is actually being closed. Any implicitly closed elements that
are popped off the stack will not be assigned an end source span, as the
implicit closing implies that no ending element is present.

Note that there is a difference between self-closed elements such as `<input/>`
and implicitly closed elements such as `<input>`. The former does have an end
source span (identical to its start source span) whereas the latter does not.

crisbeto 38a7021d5e fix(core): error due to integer overflow when there are too many host bindings (#38014)
We currently use 16 bits to store information about nodes in a view.
The 16 bits give us 65536 entries in the array, but the problem is that while
the number is large, it can be reached by ~4300 directive instances with host
bindings which could realistically happen is a very large view, as seen in #37876.
Once we hit the limit, we end up overflowing which eventually leads to a runtime error.

These changes bump to using 20 bits which gives us around 1048576 entries in
the array or 16 times more than the current amount which could still technically
be reached, but is much less likely and the user may start hitting browser limitations
by that point.

I picked the 20 bit number since it gives us enough buffer over the 16 bit one,
while not being as massive as a 24 bit or 32 bit.

I've also added a dev mode assertion so it's easier to track down if it happens
again in the future.

Misko Hevery 737506e79c fix(core): Allow modification of lifecycle hooks any time before bootstrap (#35464)
Currently we read lifecycle hooks eagerly during `ɵɵdefineComponent`.
The result is that it is not possible to do any sort of meta-programing
such as mixins or adding lifecycle hooks using custom decorators since
any such code executes after `ɵɵdefineComponent` has extracted the
lifecycle hooks from the prototype. Additionally the behavior is
inconsistent between AOT and JIT mode. In JIT mode overriding lifecycle
hooks is possible because the whole `ɵɵdefineComponent` is placed in
getter which is executed lazily. This is because JIT mode must compile a
template which can be specified as `templateURL` and those we are
waiting for its resolution.

- `+` `ɵɵdefineComponent` becomes smaller as it no longer needs to copy
  lifecycle hooks from prototype to `ComponentDef`
- `-` `ɵɵNgOnChangesFeature` feature is now always included with the
  codebase as it is no longer tree shakable.

Previously we have read lifecycle hooks from prototype in the
`ɵɵdefineComponent` so that lifecycle hook access would be monomorphic.
This decision was made before we had `T*` data structures. By not
reading the lifecycle hooks we are moving the megamorhic read form
`ɵɵdefineComponent` to instructions. However, the reads happen on
`firstTemplatePass` only and are subsequently cached in the `T*` data
structures. The result is that the overall performance should be same
(or slightly better as the intermediate `ComponentDef` has been
removed.)

- [ ] Remove `ɵɵNgOnChangesFeature` from compiler. (It will no longer
      be a feature.)
- [ ] Discuss the future of `Features` as they hinder meta-programing.

Paul Gschwendtner 1550663b9e fix(bazel): ng_module rule does not expose flat module information in Ivy (#36971)
The `ng_module` rule supports the generation of flat module bundles. In
View Engine, information about this flat module bundle is exposed
as a Bazel provider. This is helpful as other rules like `ng_package`
could rely on this information to determine entry-points for the APF.

With Ivy this currently does not work because the flat module
information is not exposed in the provider. The reason for this is
unclear. We should also provide this information in Ivy so that rules
like `ng_package` can also determine the correct entry-points when a
package is built specifically with `--config=ivy`.

The Angular ServiceWorker can serve requests to a special virtual path,
`ngsw/state`, showing [information about its internal state][1], which
can be useful for debugging.

Previously, this would only work if the ServiceWorker's [scope][2] was
the root directory (`/`). Otherwise, (e.g. when building the app with
`--baseHref=/some/path/`), the ServiceWorker would fail to detect a
request to `/some/path/ngsw/state` as matching `ngsw/state` and would
not serve it with the debugging information.

Paul Gschwendtner 6b731a067a test: fix test failure in saucelabs ivy ie10 (#37892)
One of the ivy acceptance tests currently fails in IE10. This
is because we recently added a new test that asserts that injecting
`ViewRef` results in a `NullInjectorError`.

Due to limitations in TypeScript and in polyfills for `setPrototypeOf`,
the error cannot be thrown as `ViewRef` is always considered injectable.
In reality, `ViewRef` should not be injectable, as explicitly noted
in c00f4ab2ae.

There seems no way to simulate the proper prototype chain in such
browsers that do not natively support `__proto__`, so TypeScript
and `core-js` polyfills simply break the prototype chain and
assign inherited properties directly on `ViewRef`. i.e. so that
`ViewRef.__NG_ELEMENT_ID__` exists and DI picks it up.

There is a way for TypeScript to theoretically generate proper
prototype chain in ES5 output, but they intend to only bother
about the proper prototype chain in ES6 where `setPrototypeOf`
etc. are offically standarized. See the response:

* 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

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.

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).

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

Alex Rickabaugh 8572e885b4 test(compiler-cli): fix assertion of diagnostic filename on Windows (#37758)
Several partial_evaluator tests in the diagnostics_spec check assert
correctness of diagnostic filenames. Previously these assertions compared
a resolved (`absoluteFrom`) filename with the TypeScript `ts.SourceFile`'s
`fileName` string, which caused the tests to fail on Windows because the
drive letter case differed.

This commit changes the assertions to use `absoluteFromSourceFile` instead
of the `fileName` string, resulting in an apples-to-apples comparison of
canonicalized paths.

Adam d37049a2a2 feat(platform-server): add option for absolute URL HTTP support (#37539)
In version 10.0.0-next.8, we introduced absolute URL support for
server-based HTTP requests, so long as the fully-resolved URL was
provided in the initial config. However, doing so represents a
breaking change for users who already have their own interceptors
to model this functionality, since our logic executes before all
interceptors fire on a request. See original PR #37071.

Therefore, we introduce a flag to make this change consistent with
v9 behavior, allowing users to opt in to this new behavior. This
commit also fixes two issues with the previous implementation:
1. if the server was initiated with a relative URL, the absolute
URL construction would fail because needed components were empty
2. if the user's absolute URL was on a port, the port would not
be included

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).

Fixes #37726.

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.

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

through linked `node_modules`, and build optimizer is able to properly

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

* 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:

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.

Jan Krems 7ac166ff08 feat(bazel): expose explicit mapping from closure to devmode files (#36262)
This feature is aimed at development tooling that has to translate
production build inputs into their devmode equivalent. The current
process involves guessing the devmode filename based on string
replace patterns. This allows consuming build actions to read the

This is a change in anticipation of an update to the general
Typescript build rules to consume this data.

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.

Andrew Scott d3a817549b fix(router): fix navigation ignoring logic to compare to the browser url (#37408)
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.

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.

Closes #21152. Related to #36144.
