JiaLiPassion 41667de778 fix(zone.js): add issue numbers of `@types/jasmine` to the test cases (#34625)
Some cases will still need to use `spy as any` cast, because `@types/jasmine` have some issues,
1. The issue jasmine doesn't handle optional method properties, https://github.com/DefinitelyTyped/DefinitelyTyped/issues/43486
2. The issue jasmine doesn't handle overload method correctly, https://github.com/DefinitelyTyped/DefinitelyTyped/issues/42455

1. update jasmine to 3.5
2. update @types/jasmine to 3.5
3. update @types/jasminewd2 to 2.0.8

Also fix several cases, the new jasmine 3 will help to create test cases correctly,
such as in the `jasmine 2.x` version, the following case will pass

```
expect(1 == 2);
```

But in jsamine 3, the case will need to be

```
expect(1 == 2).toBeTrue();
```

JiaLiPassion 4374931b0e fix(zone.js): zone.js patch jest should handle done correctly (#36022)
`zone.js` supports jest `test.each()` methods, but it
introduces a bug, which is the `done()` function will not be handled correctly.

```
it('should work with done', done => {
  // done will be undefined.
});
```

The reason is the logic of monkey patching `test` method is different from `jasmine` patch

// jasmine patch
```
return testBody.length === 0
   ? () => testProxyZone.run(testBody, null)
   : done => testProxyZone.run(testBody, null, [done]);
```

// jest patch
```
 return function(...args) {
   return testProxyZone.run(testBody, null, args);
 };
```

the purpose of this change is to handle the following cases.

```
test.each([1, 2])('test.each', (arg1, arg2) => {
  expect(arg1).toBe(1);
  expect(arg2).toBe(2);
});
```

so in jest, it is a little complex, because the `testBody`'s parameter may be bigger than 1, so the
logic in `jasmine`

```
return testBody.length === 0
   ? () => testProxyZone.run(testBody, null)
   : done => testProxyZone.run(testBody, null, [done]);
```
will not work for `test.each` in jest.

So in this PR, I created a dynamic `Function` to return the correct length of paramters (which is required by jest core), to handle
1. normal `test` with or without `done`.
2. each with parameters with or without done.

JoostK 64022f51d4 fix(compiler): resolve enum values in binary operations (#36461)
During static evaluation of expressions, the partial evaluator
may come across a binary + operator for which it needs to
evaluate its operands. Any of these operands may be a reference
to an enum member, in which case the enum member's value needs
to be used as literal value, not the enum member reference
itself. This commit fixes the behavior by resolving an

crisbeto 95fc3d4c5c fix(core): ngOnDestroy on multi providers called with incorrect context (#35840)
Currently destroy hooks are stored in memory as `[1, hook, 5, hook]` where
the numbers represent the index at which to find the context and `hook` is
the function to be invoked. This breaks down for `multi` providers,
because the value at the index will be an array of providers, resulting in
the hook being invoked with an array of all the multi provider values,
rather than the provider that was destroyed. In ViewEngine `ngOnDestroy`
wasn't being called for `multi` providers at all.

These changes fix the issue by changing the structure of the destroy hooks to `[1, hook, 5, [0, hook, 3, hook]]` where the indexes inside the inner array point to the provider inside of the multi provider array. Note that this is slightly different from the original design which called for the structure to be `[1, hook, 5, [hook, hook]`, because in the process of implementing it, I realized that we wouldn't get passing the correct context if only some of the `multi` providers have `ngOnDestroy` and others don't.

I've run the newly-added `view_destroy_hooks` benchmark against these changes and compared it to master. The difference seems to be insignificant (between 1% and 2% slower).

Fixes #35231.

George Kalpakas 5fa7b8ba56 fix(ngcc): detect non-emitted, non-imported TypeScript helpers (#36418)
When TypeScript downlevels ES2015+ code to ES5, it uses some helper
functions to emulate some ES2015+ features, such as spread syntax. The
TypeScript compiler can be configured to emit these helpers into the
transpiled code (which is controlled by the `noEmitHelpers` option -
false by default). It can also be configured to import these helpers
from the `tslib` module (which is controlled by the `importHelpers`
option - false by default).

While most of the time the helpers will be either emitted or imported,
it is possible that one configures their app to neither emit nor import
them. In that case, the helpers could, for example, be made available on
the global object. This is what `@nativescript/angular`
v9.0.0-next-2019-11-12-155500-01 does. See, for example, [common.js][1].

Ngcc must be able to detect and statically evaluate these helpers.
Previously, it was only able to detect emitted or imported helpers.

This commit adds support for detecting these helpers if they are neither
emitted nor imported. It does this by checking identifiers for which no
declaration (either concrete or inline) can be found against a list of
known TypeScript helper function names.

Paul Gschwendtner d43c30688a fix(core): avoid migration error when non-existent symbol is imported (#36367)
In rare cases a project with configured `rootDirs` that has imports to
non-existent identifiers could fail in the migration.

This happens because based on the application code, the migration could
end up trying to resolve the `ts.Symbol` of such non-existent
identifiers. This isn't a problem usually, but due to a upstream bug
in the TypeScript compiler, a runtime error is thrown.

This is because TypeScript is unable to compute a relative path from the
originating source file to the imported source file which _should_
provide the non-existent identifier. An issue for this has been reported
upstream: https://github.com/microsoft/TypeScript/issues/37731. The
issue only surfaces since our migrations don't provide an absolute base
path that is used for resolving the root directories.

To fix this, we ensure that we never use relative paths when parsing
tsconfig files. More details can be found in the TS issue.

Fixes #36346.

George Kalpakas ca25c957bf fix(ngcc): correctly detect imported TypeScript helpers (#36284)
The `NgccReflectionHost`s have logic for detecting certain known
declarations (such as `Object.assign()` and TypeScript helpers), which
allows the `PartialEvaluator` to evaluate expressions it would not be
able to statically evaluate otherwise.

In #36089, `DelegatingReflectionHost` was introduced, which delegates to
a TypeScript `ReflectionHost` when reflecting on TypeScript files, which
for ngcc's case means `.d.ts` files of dependencies. As a result, ngcc
lost the ability to detect TypeScript helpers imported from `tslib`,
because `DelegatingReflectionHost` was not able to apply the known
declaration detection logic while reflecting on `tslib`'s `.d.ts` files.

This commit fixes this by ensuring `DelegatingReflectionHost` calls the
`NgccReflectionHost`'s `detectKnownDeclaration()` method as necessary,
even when using the TypeScript `ReflectionHost`.

NOTE:
The previous commit exposed a bug in ngcc that was hidden due to the
tests' being inconsistent with how the `ReflectionHost`s are used in the
actual program. The changes in this commit are verified by ensuring the
failing tests are now passing (hence no new tests are added).

George Kalpakas 93f07aee6c test(ngcc): use `DelegatingReflectionHost` for testing `NgccReflectionHost`s (#36284)
In #36089, `DelegatingReflectionHost` was introduced. Under the hood, it
delegates another `NgccReflectionHost` in order to reflect over the
program's source files, while using a different TypeScript
`ReflectionHost` to reflect over `.d.ts` files (which is how external
dependencies are represented in the program).

Previously, the `NgccReflectionHost`s were used directly in tests. This
does not exercise them in the way they are exercised in the actual
program, because (when used directly) they will also reflect on `.d.ts`
files too (instead of delegating to the TypeScript `ReflectionHost`).
This could hide bugs that would happen on the actual program.

This commit fixes this by using the `DelegatingReflectionHost` in the
various `NgccReflectionHost` tests.

NOTE:
This change will cause some of the existing tests to start failing.
These failures demonstrate pre-existing bugs in ngcc, that were hidden
due to the tests' being inconsistent with how the `ReflectionHost`s are
used in the actual program. They will be fixed in the next commit.

Paul Gschwendtner c24ad560fa feat(core): undecorated-classes migration should handle derived abstract classes (#35339)
In version 10, undecorated base classes that use Angular features need
to be decorated explicitly with `@Directive()`. Additionally, derived
classes of abstract directives need to be decorated.

The migration already handles this for undecorated classes that are
not explicitly decorated, but since in V9, abstract directives can be
used, we also need to handle this for explicitly decorated abstract
directives. e.g.

```
@Directive()

Paul Gschwendtner 32eafef6a7 fix(core): undecorated-classes-with-decorated-fields migration does not decorate derived classes (#35339)
The `undecorated-classes-with-decorated-fields` migration has been
introduced with 904a2018e0, but misses
logic for decorating derived classes of undecorated classes which use
Angular features. Example scenario:

```ts
export abstract class MyBaseClass {
  @Input() someInput = true;
}

export abstract class BaseClassTwo extends MyBaseClass {}

@Component(...)
export class MyButton extends BaseClassTwo {}
```

Both abstract classes would need to be migrated. Previously, the migration
only added `@Directive()` to `MyBaseClass`, but with this change, it
also decorates `BaseClassTwo`.

This is necessary because the Angular Compiler requires `BaseClassTwo` to
have a directive definition when it flattens the directive metadata for
`MyButton` in order to perform type checking. Technically, not decorating
`BaseClassTwo` does not break at runtime.

We basically want to enforce consistent use of `@Directive` to simplify the
mental model. [See the migration guide](https://angular.io/guide/migration-undecorated-classes#migrating-classes-that-use-field-decorators).

JoostK 75afd80ae8 refactor(compiler): add `@nocollapse` annotation using a synthetic comment (#35932)
In Ivy, Angular decorators are compiled into static fields that are
inserted into a class declaration in a TypeScript transform. When
targeting Closure compiler such fields need to be annotated with
`@nocollapse` to prevent them from being lifted from a static field into
a variable, as that would prevent the Ivy runtime from being able to
find the compiled definitions.

Previously, there was a bug in TypeScript where synthetic comments added
in a transform would not be emitted at all, so as a workaround a global
regex-replace was done in the emit's `writeFile` callback that would add
the `@nocollapse` annotation to all static Ivy definition fields. This
approach is no longer possible when ngtsc is running as TypeScript
plugin, as a plugin cannot control emit behavior.

The workaround is no longer necessary, as synthetic comments are now
properly emitted, likely as of
https://github.com/microsoft/TypeScript/pull/22141 which has been
released with TypeScript 2.8.

This change is required for running ngtsc as TypeScript plugin in
Bazel's `ts_library` rule, to move away from the custom `ngc_wrapped`
approach.

package, it defaults to `*` (with the intention of matching any
version).

Previously, the installed version of a package was tested against the
version range using the [semver][1] package's `satisfies()` function
with the default options. By default, `satisfies()` does not match
pre-releases (see [here][2] for more details on reasoning). While this
makes sense when determining what version of a dependency to install
(trying to avoid unexpected breaking changes), it is not desired in the
case of ngcc.

This commit fixes it by explicitly specifying that pre-release versions
should be matched normally.

Keen Yee Liau 5516802142 fix(compiler): avoid undefined expressions in holey array (#36343)
From G3 bug ID: 116443331

The View Engine compiler crashes when it tries to compile a test in JIT mode
that includes the d3-scale-chromatic library [1]. The d3 package initializes
some arrays using the following pattern:

```js
export var scheme = new Array(3).concat(
  "d8b365f5f5f55ab4ac",
  // ... more entries
).map(colors);
```

The stack trace from the crash is as follows:

```
TypeError: Cannot read property 'visitExpression' of undefined

```

This is because the corresponding output AST for the array is of the form

```ts
[
  undefined,
  undefined,
  undefined,
  o.LiteralExpr,
  // ...
]
```

The output AST is clearly malformed and breaks the type representation of
`LiteralArrayExpr` in which every entry is expected to be of type `Expression`.

This commit fixes the bug by using a plain `for` loop to iterate over the
entire length of the holey array and convert undefined elements to
`LiteralExpr`.

Pete Bacon Darwin cc4b813e75 fix(ngcc): handle bad path mappings when finding entry-points (#36331)
Previously, a bad baseUrl or path mapping passed to an `EntryPointFinder`
could cause the original `sourceDirectory` to be superceded by a higher
directory. This could result in none of the sourceDirectory entry-points being
processed.

Now missing basePaths computed from path-mappings are discarded with
a warning. Further, if the `baseUrl` is the root directory then a warning is
given as this is most likely an error in the tsconfig.json.

Ayaz Hafiz fe2b6923ba fix(language-service): infer type of elements of array-like objects (#36312)
Currently the language service only provides support for determining the
type of array-like members when the array-like object is an `Array`.
However, there are other kinds of array-like objects, including
`ReadonlyArray`s and `readonly`-property arrays. This commit adds
support for retrieving the element type of arbitrary array-like objects.

Pete Bacon Darwin 38ad1d97ab fix(ngcc): handle entry-points within container folders (#36305)
The previous optimizations in #35756 to the
`DirectoryWalkerEntryPointFinder` were over zealous
with regard to packages that have entry-points stored
in "container" directories in the package, where the
container directory was not an entry-point itself.

Now we will also walk such "container" folders as long
as they do not contain `.js` files, which we regard as an
indicator that the directory will not contain entry-points.
