refactor(ivy): implement a virtual file-system layer in ngtsc + ngcc (#30921) To improve cross platform support, all file access (and path manipulation) is now done through a well known interface (`FileSystem`). For testing a number of `MockFileSystem` implementations are provided. These provide an in-memory file-system which emulates operating systems like OS/X, Unix and Windows. The current file system is always available via the static method, `FileSystem.getFileSystem()`. This is also used by a number of static methods on `AbsoluteFsPath` and `PathSegment`, to avoid having to pass `FileSystem` objects around all the time. The result of this is that one must be careful to ensure that the file-system has been initialized before using any of these static methods. To prevent this happening accidentally the current file system always starts out as an instance of `InvalidFileSystem`, which will throw an error if any of its methods are called. You can set the current file-system by calling `FileSystem.setFileSystem()`. During testing you can call the helper function `initMockFileSystem(os)` which takes a string name of the OS to emulate, and will also monkey-patch aspects of the TypeScript library to ensure that TS is also using the current file-system. Finally there is the `NgtscCompilerHost` to be used for any TypeScript compilation, which uses a given file-system. All tests that interact with the file-system should be tested against each of the mock file-systems. A series of helpers have been provided to support such tests: * `runInEachFileSystem()` - wrap your tests in this helper to run all the wrapped tests in each of the mock file-systems. * `addTestFilesToFileSystem()` - use this to add files and their contents to the mock file system for testing. * `loadTestFilesFromDisk()` - use this to load a mirror image of files on disk into the in-memory mock file-system. * `loadFakeCore()` - use this to load a fake version of `@angular/core` into the mock file-system. All ngcc and ngtsc source and tests now use this virtual file-system setup. PR Close #30921

refactor(ivy): implement a virtual file-system layer in ngtsc + ngcc (#30921) To improve cross platform support, all file access (and path manipulation) is now done through a well known interface (`FileSystem`). For testing a number of `MockFileSystem` implementations are provided. These provide an in-memory file-system which emulates operating systems like OS/X, Unix and Windows. The current file system is always available via the static method, `FileSystem.getFileSystem()`. This is also used by a number of static methods on `AbsoluteFsPath` and `PathSegment`, to avoid having to pass `FileSystem` objects around all the time. The result of this is that one must be careful to ensure that the file-system has been initialized before using any of these static methods. To prevent this happening accidentally the current file system always starts out as an instance of `InvalidFileSystem`, which will throw an error if any of its methods are called. You can set the current file-system by calling `FileSystem.setFileSystem()`. During testing you can call the helper function `initMockFileSystem(os)` which takes a string name of the OS to emulate, and will also monkey-patch aspects of the TypeScript library to ensure that TS is also using the current file-system. Finally there is the `NgtscCompilerHost` to be used for any TypeScript compilation, which uses a given file-system. All tests that interact with the file-system should be tested against each of the mock file-systems. A series of helpers have been provided to support such tests: * `runInEachFileSystem()` - wrap your tests in this helper to run all the wrapped tests in each of the mock file-systems. * `addTestFilesToFileSystem()` - use this to add files and their contents to the mock file system for testing. * `loadTestFilesFromDisk()` - use this to load a mirror image of files on disk into the in-memory mock file-system. * `loadFakeCore()` - use this to load a fake version of `@angular/core` into the mock file-system. All ngcc and ngtsc source and tests now use this virtual file-system setup. PR Close #30921

refactor(ivy): implement a virtual file-system layer in ngtsc + ngcc (#30921) To improve cross platform support, all file access (and path manipulation) is now done through a well known interface (`FileSystem`). For testing a number of `MockFileSystem` implementations are provided. These provide an in-memory file-system which emulates operating systems like OS/X, Unix and Windows. The current file system is always available via the static method, `FileSystem.getFileSystem()`. This is also used by a number of static methods on `AbsoluteFsPath` and `PathSegment`, to avoid having to pass `FileSystem` objects around all the time. The result of this is that one must be careful to ensure that the file-system has been initialized before using any of these static methods. To prevent this happening accidentally the current file system always starts out as an instance of `InvalidFileSystem`, which will throw an error if any of its methods are called. You can set the current file-system by calling `FileSystem.setFileSystem()`. During testing you can call the helper function `initMockFileSystem(os)` which takes a string name of the OS to emulate, and will also monkey-patch aspects of the TypeScript library to ensure that TS is also using the current file-system. Finally there is the `NgtscCompilerHost` to be used for any TypeScript compilation, which uses a given file-system. All tests that interact with the file-system should be tested against each of the mock file-systems. A series of helpers have been provided to support such tests: * `runInEachFileSystem()` - wrap your tests in this helper to run all the wrapped tests in each of the mock file-systems. * `addTestFilesToFileSystem()` - use this to add files and their contents to the mock file system for testing. * `loadTestFilesFromDisk()` - use this to load a mirror image of files on disk into the in-memory mock file-system. * `loadFakeCore()` - use this to load a fake version of `@angular/core` into the mock file-system.

refactor(ivy): ngcc - categorize the various decorate calls upfront (#31614) Any decorator information present in TypeScript is emitted into the generated JavaScript sources by means of `__decorate` call. This call contains both the decorators as they existed in the original source code, together with calls to `tslib` helpers that convey additional information on e.g. type information and parameter decorators. These different kinds of decorator calls were not previously distinguished on their own, but instead all treated as `Decorator` by themselves. The "decorators" that were actually `tslib` helper calls were conveniently filtered out because they were not imported from `@angular/core`, a characteristic that ngcc uses to drop certain decorators. Note that this posed an inconsistency in ngcc when it processes `@angular/core`'s UMD bundle, as the `tslib` helper functions have been inlined in said bundle. Because of the inlining, the `tslib` helpers appear to be from `@angular/core`, so ngcc would fail to drop those apparent "decorators". This inconsistency does not currently cause any issues, as ngtsc is specifically looking for decorators based on their name and any remaining decorators are simply ignored. This commit rewrites the decorator analysis of a class to occur all in a single phase, instead of all throughout the `ReflectionHost`. This allows to categorize the various decorate calls in a single sweep, instead of constantly needing to filter out undesired decorate calls on the go. As an added benefit, the computed decorator information is now cached per class, such that subsequent reflection queries that need decorator information can reuse the cached info. PR Close #31614

Note that this posed an inconsistency in ngcc when it processes `@angular/core`'s UMD bundle, as the `tslib` helper functions have been inlined in said bundle. Because of the inlining, the `tslib` helpers appear to be from `@angular/core`, so ngcc would fail to drop those apparent "decorators". This inconsistency does not currently cause any issues, as ngtsc is specifically looking for decorators based on their name and any remaining decorators are simply ignored. This commit rewrites the decorator analysis of a class to occur all in a single phase, instead of all throughout the `ReflectionHost`. This allows to categorize the various decorate calls in a single sweep, instead of constantly needing to filter out undesired decorate calls on the go. As an added benefit, the computed decorator information is now cached per class, such that subsequent reflection queries that need decorator information can reuse the cached info. PR Close #31614

refactor(ivy): implement a virtual file-system layer in ngtsc + ngcc (#30921) To improve cross platform support, all file access (and path manipulation) is now done through a well known interface (`FileSystem`). For testing a number of `MockFileSystem` implementations are provided. These provide an in-memory file-system which emulates operating systems like OS/X, Unix and Windows. The current file system is always available via the static method, `FileSystem.getFileSystem()`. This is also used by a number of static methods on `AbsoluteFsPath` and `PathSegment`, to avoid having to pass `FileSystem` objects around all the time. The result of this is that one must be careful to ensure that the file-system has been initialized before using any of these static methods. To prevent this happening accidentally the current file system always starts out as an instance of `InvalidFileSystem`, which will throw an error if any of its methods are called. You can set the current file-system by calling `FileSystem.setFileSystem()`. During testing you can call the helper function `initMockFileSystem(os)` which takes a string name of the OS to emulate, and will also monkey-patch aspects of the TypeScript library to ensure that TS is also using the current file-system. Finally there is the `NgtscCompilerHost` to be used for any TypeScript compilation, which uses a given file-system. All tests that interact with the file-system should be tested against each of the mock file-systems. A series of helpers have been provided to support such tests: * `runInEachFileSystem()` - wrap your tests in this helper to run all the wrapped tests in each of the mock file-systems. * `addTestFilesToFileSystem()` - use this to add files and their contents to the mock file system for testing. * `loadTestFilesFromDisk()` - use this to load a mirror image of files on disk into the in-memory mock file-system. * `loadFakeCore()` - use this to load a fake version of `@angular/core` into the mock file-system.

refactor(ivy): ngcc - categorize the various decorate calls upfront (#31614) Any decorator information present in TypeScript is emitted into the generated JavaScript sources by means of `__decorate` call. This call contains both the decorators as they existed in the original source code, together with calls to `tslib` helpers that convey additional information on e.g. type information and parameter decorators. These different kinds of decorator calls were not previously distinguished on their own, but instead all treated as `Decorator` by themselves. The "decorators" that were actually `tslib` helper calls were conveniently filtered out because they were not imported from `@angular/core`, a characteristic that ngcc uses to drop certain decorators.

refactor(ivy): implement a virtual file-system layer in ngtsc + ngcc (#30921) To improve cross platform support, all file access (and path manipulation) is now done through a well known interface (`FileSystem`). For testing a number of `MockFileSystem` implementations are provided. These provide an in-memory file-system which emulates operating systems like OS/X, Unix and Windows. The current file system is always available via the static method, `FileSystem.getFileSystem()`. This is also used by a number of static methods on `AbsoluteFsPath` and `PathSegment`, to avoid having to pass `FileSystem` objects around all the time. The result of this is that one must be careful to ensure that the file-system has been initialized before using any of these static methods. To prevent this happening accidentally the current file system always starts out as an instance of `InvalidFileSystem`, which will throw an error if any of its methods are called. You can set the current file-system by calling `FileSystem.setFileSystem()`. During testing you can call the helper function `initMockFileSystem(os)` which takes a string name of the OS to emulate, and will also monkey-patch aspects of the TypeScript library to ensure that TS is also using the current file-system. Finally there is the `NgtscCompilerHost` to be used for any TypeScript compilation, which uses a given file-system. All tests that interact with the file-system should be tested against each of the mock file-systems. A series of helpers have been provided to support such tests: * `runInEachFileSystem()` - wrap your tests in this helper to run all the wrapped tests in each of the mock file-systems. * `addTestFilesToFileSystem()` - use this to add files and their contents to the mock file system for testing. * `loadTestFilesFromDisk()` - use this to load a mirror image of files on disk into the in-memory mock file-system. * `loadFakeCore()` - use this to load a fake version of `@angular/core` into the mock file-system.

refactor(ivy): implement a virtual file-system layer in ngtsc + ngcc (#30921) To improve cross platform support, all file access (and path manipulation) is now done through a well known interface (`FileSystem`). For testing a number of `MockFileSystem` implementations are provided. These provide an in-memory file-system which emulates operating systems like OS/X, Unix and Windows. The current file system is always available via the static method, `FileSystem.getFileSystem()`. This is also used by a number of static methods on `AbsoluteFsPath` and `PathSegment`, to avoid having to pass `FileSystem` objects around all the time. The result of this is that one must be careful to ensure that the file-system has been initialized before using any of these static methods. To prevent this happening accidentally the current file system always starts out as an instance of `InvalidFileSystem`, which will throw an error if any of its methods are called. You can set the current file-system by calling `FileSystem.setFileSystem()`. During testing you can call the helper function `initMockFileSystem(os)` which takes a string name of the OS to emulate, and will also monkey-patch aspects of the TypeScript library to ensure that TS is also using the current file-system. Finally there is the `NgtscCompilerHost` to be used for any TypeScript compilation, which uses a given file-system. All tests that interact with the file-system should be tested against each of the mock file-systems. A series of helpers have been provided to support such tests: * `runInEachFileSystem()` - wrap your tests in this helper to run all the wrapped tests in each of the mock file-systems. * `addTestFilesToFileSystem()` - use this to add files and their contents to the mock file system for testing. * `loadTestFilesFromDisk()` - use this to load a mirror image of files on disk into the in-memory mock file-system. * `loadFakeCore()` - use this to load a fake version of `@angular/core` into the mock file-system.

For testing a number of `MockFileSystem` implementations are provided. These provide an in-memory file-system which emulates operating systems like OS/X, Unix and Windows. The current file system is always available via the static method, `FileSystem.getFileSystem()`. This is also used by a number of static methods on `AbsoluteFsPath` and `PathSegment`, to avoid having to pass `FileSystem` objects around all the time. The result of this is that one must be careful to ensure that the file-system has been initialized before using any of these static methods. To prevent this happening accidentally the current file system always starts out as an instance of `InvalidFileSystem`, which will throw an error if any of its methods are called. You can set the current file-system by calling `FileSystem.setFileSystem()`. During testing you can call the helper function `initMockFileSystem(os)` which takes a string name of the OS to emulate, and will also monkey-patch aspects of the TypeScript library to ensure that TS is also using the current file-system. Finally there is the `NgtscCompilerHost` to be used for any TypeScript compilation, which uses a given file-system. All tests that interact with the file-system should be tested against each of the mock file-systems. A series of helpers have been provided to support such tests: * `runInEachFileSystem()` - wrap your tests in this helper to run all the wrapped tests in each of the mock file-systems. * `addTestFilesToFileSystem()` - use this to add files and their contents to the mock file system for testing. * `loadTestFilesFromDisk()` - use this to load a mirror image of files on disk into the in-memory mock file-system. * `loadFakeCore()` - use this to load a fake version of `@angular/core` into the mock file-system.

refactor(ivy): ngcc - categorize the various decorate calls upfront (#31614) Any decorator information present in TypeScript is emitted into the generated JavaScript sources by means of `__decorate` call. This call contains both the decorators as they existed in the original source code, together with calls to `tslib` helpers that convey additional information on e.g. type information and parameter decorators. These different kinds of decorator calls were not previously distinguished on their own, but instead all treated as `Decorator` by themselves. The "decorators" that were actually `tslib` helper calls were conveniently filtered out because they were not imported from `@angular/core`, a characteristic that ngcc uses to drop certain decorators. Note that this posed an inconsistency in ngcc when it processes `@angular/core`'s UMD bundle, as the `tslib` helper functions have been inlined in said bundle. Because of the inlining, the `tslib` helpers appear to be from `@angular/core`, so ngcc would fail to drop those apparent "decorators". This inconsistency does not currently cause any issues, as ngtsc is specifically looking for decorators based on their name and any remaining decorators are simply ignored. This commit rewrites the decorator analysis of a class to occur all in a single phase, instead of all throughout the `ReflectionHost`. This allows to categorize the various decorate calls in a single sweep, instead of constantly needing to filter out undesired decorate calls on the go. As an added benefit, the computed decorator information is now cached per class, such that subsequent reflection queries that need decorator information can reuse the cached info. PR Close #31614

refactor(ivy): implement a virtual file-system layer in ngtsc + ngcc (#30921) To improve cross platform support, all file access (and path manipulation) is now done through a well known interface (`FileSystem`). For testing a number of `MockFileSystem` implementations are provided. These provide an in-memory file-system which emulates operating systems like OS/X, Unix and Windows. The current file system is always available via the static method, `FileSystem.getFileSystem()`. This is also used by a number of static methods on `AbsoluteFsPath` and `PathSegment`, to avoid having to pass `FileSystem` objects around all the time.

To prevent this happening accidentally the current file system always starts out as an instance of `InvalidFileSystem`, which will throw an error if any of its methods are called. You can set the current file-system by calling `FileSystem.setFileSystem()`.

fix(ivy): in ngcc, handle inline exports in commonjs code (#32129) One of the compiler's tasks is to enumerate the exports of a given ES module. This can happen for example to resolve `foo.bar` where `foo` is a namespace import: ```typescript import * as foo from './foo'; @NgModule({ directives: [foo.DIRECTIVES], }) ``` In this case, the compiler must enumerate the exports of `foo.ts` in order to evaluate the expression `foo.DIRECTIVES`. When this operation occurs under ngcc, it must deal with the different module formats and types of exports that occur. In commonjs code, a problem arises when certain exports are downleveled. ```typescript export const DIRECTIVES = [ FooDir, BarDir, ]; ``` can be downleveled to: ```javascript exports.DIRECTIVES = [ FooDir, BarDir, ``` Previously, ngtsc and ngcc expected that any export would have an associated `ts.Declaration` node. `export class`, `export function`, etc. all retain `ts.Declaration`s even when downleveled. But the `export const` construct above does not. Therefore, ngcc would not detect `DIRECTIVES` as an export of `foo.ts`, and the evaluation of `foo.DIRECTIVES` would therefore fail. To solve this problem, the core concept of an exported `Declaration` according to the `ReflectionHost` API is split into a `ConcreteDeclaration` which has a `ts.Declaration`, and an `InlineDeclaration` which instead has a `ts.Expression`. Differentiating between these allows ngcc to return an `InlineDeclaration` for `DIRECTIVES` and correctly keep track of this export. PR Close #32129

fix(ngcc): consistently use outer declaration for classes (#32539) In ngcc's reflection hosts for compiled JS bundles, such as ESM2015, special care needs to be taken for classes as there may be an outer declaration (referred to as "declaration") and an inner declaration (referred to as "implementation") for a given class. Therefore, there will also be two `ts.Symbol`s bound per class, and ngcc needs to switch between those declarations and symbols depending on where certain information can be found. Prior to this commit, the `NgccReflectionHost` interface had methods `getClassSymbol` and `findClassSymbols` that would return a `ts.Symbol`. These class symbols would be used to kick off compilation of components using ngtsc, so it is important for these symbols to correspond with the publicly visible outer declaration of the class. However, the ESM2015 reflection host used to return the `ts.Symbol` for the inner declaration, if the class was declared as follows: ```javascript var MyClass = class MyClass {}; ``` For the above code, `Esm2015ReflectionHost.getClassSymbol` would return the `ts.Symbol` corresponding with the `class MyClass {}` declaration, whereas it should have corresponded with the `var MyClass` declaration. As a consequence, no `NgModule` could be resolved for the component, so no components/directives would be in scope for the component. This resulted in errors during runtime. This commit resolves the issue by introducing a `NgccClassSymbol` that contains references to both the outer and inner `ts.Symbol`, instead of just a single `ts.Symbol`. This avoids the unclarity of whether a `ts.Symbol` corresponds with the outer or inner declaration.

For testing a number of `MockFileSystem` implementations are provided. These provide an in-memory file-system which emulates operating systems like OS/X, Unix and Windows. The current file system is always available via the static method, `FileSystem.getFileSystem()`. This is also used by a number of static methods on `AbsoluteFsPath` and `PathSegment`, to avoid having to pass `FileSystem` objects around all the time. The result of this is that one must be careful to ensure that the file-system has been initialized before using any of these static methods. To prevent this happening accidentally the current file system always starts out as an instance of `InvalidFileSystem`, which will throw an error if any of its methods are called. You can set the current file-system by calling `FileSystem.setFileSystem()`. During testing you can call the helper function `initMockFileSystem(os)` which takes a string name of the OS to emulate, and will also monkey-patch aspects of the TypeScript library to ensure that TS is also using the current file-system. Finally there is the `NgtscCompilerHost` to be used for any TypeScript compilation, which uses a given file-system. All tests that interact with the file-system should be tested against each of the mock file-systems. A series of helpers have been provided to support such tests: * `runInEachFileSystem()` - wrap your tests in this helper to run all the wrapped tests in each of the mock file-systems. * `addTestFilesToFileSystem()` - use this to add files and their contents to the mock file system for testing. * `loadTestFilesFromDisk()` - use this to load a mirror image of files on disk into the in-memory mock file-system. * `loadFakeCore()` - use this to load a fake version of `@angular/core` into the mock file-system.

fix(ngcc): consistently use outer declaration for classes (#32539) In ngcc's reflection hosts for compiled JS bundles, such as ESM2015, special care needs to be taken for classes as there may be an outer declaration (referred to as "declaration") and an inner declaration (referred to as "implementation") for a given class. Therefore, there will also be two `ts.Symbol`s bound per class, and ngcc needs to switch between those declarations and symbols depending on where certain information can be found. Prior to this commit, the `NgccReflectionHost` interface had methods `getClassSymbol` and `findClassSymbols` that would return a `ts.Symbol`. These class symbols would be used to kick off compilation of components using ngtsc, so it is important for these symbols to correspond with the publicly visible outer declaration of the class. However, the ESM2015 reflection host used to return the `ts.Symbol` for the inner declaration, if the class was declared as follows: ```javascript var MyClass = class MyClass {}; ``` For the above code, `Esm2015ReflectionHost.getClassSymbol` would return the `ts.Symbol` corresponding with the `class MyClass {}` declaration, whereas it should have corresponded with the `var MyClass` declaration. As a consequence, no `NgModule` could be resolved for the component, so no components/directives would be in scope for the component. This resulted in errors during runtime. This commit resolves the issue by introducing a `NgccClassSymbol` that contains references to both the outer and inner `ts.Symbol`, instead of just a single `ts.Symbol`. This avoids the unclarity of whether a `ts.Symbol` corresponds with the outer or inner declaration.

refactor(ivy): implement a virtual file-system layer in ngtsc + ngcc (#30921) To improve cross platform support, all file access (and path manipulation) is now done through a well known interface (`FileSystem`). For testing a number of `MockFileSystem` implementations are provided. These provide an in-memory file-system which emulates operating systems like OS/X, Unix and Windows. The current file system is always available via the static method, `FileSystem.getFileSystem()`. This is also used by a number of static methods on `AbsoluteFsPath` and `PathSegment`, to avoid having to pass `FileSystem` objects around all the time. The result of this is that one must be careful to ensure that the file-system has been initialized before using any of these static methods. To prevent this happening accidentally the current file system always starts out as an instance of `InvalidFileSystem`, which will throw an error if any of its methods are called. You can set the current file-system by calling `FileSystem.setFileSystem()`. During testing you can call the helper function `initMockFileSystem(os)` which takes a string name of the OS to emulate, and will also monkey-patch aspects of the TypeScript library to ensure that TS is also using the current file-system. Finally there is the `NgtscCompilerHost` to be used for any TypeScript compilation, which uses a given file-system. All tests that interact with the file-system should be tested against each of the mock file-systems. A series of helpers have been provided to support such tests: * `runInEachFileSystem()` - wrap your tests in this helper to run all the wrapped tests in each of the mock file-systems. * `addTestFilesToFileSystem()` - use this to add files and their contents to the mock file system for testing. * `loadTestFilesFromDisk()` - use this to load a mirror image of files on disk into the in-memory mock file-system. * `loadFakeCore()` - use this to load a fake version of `@angular/core` into the mock file-system.

fix(ngcc): consistently use outer declaration for classes (#32539) In ngcc's reflection hosts for compiled JS bundles, such as ESM2015, special care needs to be taken for classes as there may be an outer declaration (referred to as "declaration") and an inner declaration (referred to as "implementation") for a given class. Therefore, there will also be two `ts.Symbol`s bound per class, and ngcc needs to switch between those declarations and symbols depending on where certain information can be found. Prior to this commit, the `NgccReflectionHost` interface had methods `getClassSymbol` and `findClassSymbols` that would return a `ts.Symbol`. These class symbols would be used to kick off compilation of components using ngtsc, so it is important for these symbols to correspond with the publicly visible outer declaration of the class. However, the ESM2015 reflection host used to return the `ts.Symbol` for the inner declaration, if the class was declared as follows: ```javascript var MyClass = class MyClass {}; ``` For the above code, `Esm2015ReflectionHost.getClassSymbol` would return the `ts.Symbol` corresponding with the `class MyClass {}` declaration, whereas it should have corresponded with the `var MyClass` declaration. As a consequence, no `NgModule` could be resolved for the component, so no components/directives would be in scope for the component. This resulted in errors during runtime. This commit resolves the issue by introducing a `NgccClassSymbol` that contains references to both the outer and inner `ts.Symbol`, instead of just a single `ts.Symbol`. This avoids the unclarity of whether a `ts.Symbol` corresponds with the outer or inner declaration.

refactor(ivy): implement a virtual file-system layer in ngtsc + ngcc (#30921) To improve cross platform support, all file access (and path manipulation) is now done through a well known interface (`FileSystem`). For testing a number of `MockFileSystem` implementations are provided. These provide an in-memory file-system which emulates operating systems like OS/X, Unix and Windows. The current file system is always available via the static method, `FileSystem.getFileSystem()`. This is also used by a number of static methods on `AbsoluteFsPath` and `PathSegment`, to avoid having to pass `FileSystem` objects around all the time. The result of this is that one must be careful to ensure that the file-system has been initialized before using any of these static methods. To prevent this happening accidentally the current file system always starts out as an instance of `InvalidFileSystem`, which will throw an error if any of its methods are called. You can set the current file-system by calling `FileSystem.setFileSystem()`. During testing you can call the helper function `initMockFileSystem(os)` which takes a string name of the OS to emulate, and will also monkey-patch aspects of the TypeScript library to ensure that TS is also using the current file-system. Finally there is the `NgtscCompilerHost` to be used for any TypeScript compilation, which uses a given file-system. All tests that interact with the file-system should be tested against each of the mock file-systems. A series of helpers have been provided to support such tests: * `runInEachFileSystem()` - wrap your tests in this helper to run all the wrapped tests in each of the mock file-systems. * `addTestFilesToFileSystem()` - use this to add files and their contents to the mock file system for testing. * `loadTestFilesFromDisk()` - use this to load a mirror image of files on disk into the in-memory mock file-system. * `loadFakeCore()` - use this to load a fake version of `@angular/core` into the mock file-system.

refactor(ivy): implement a virtual file-system layer in ngtsc + ngcc (#30921) To improve cross platform support, all file access (and path manipulation) is now done through a well known interface (`FileSystem`). For testing a number of `MockFileSystem` implementations are provided. These provide an in-memory file-system which emulates operating systems like OS/X, Unix and Windows. The current file system is always available via the static method, `FileSystem.getFileSystem()`. This is also used by a number of static methods on `AbsoluteFsPath` and `PathSegment`, to avoid having to pass `FileSystem` objects around all the time. The result of this is that one must be careful to ensure that the file-system has been initialized before using any of these static methods. To prevent this happening accidentally the current file system always starts out as an instance of `InvalidFileSystem`, which will throw an error if any of its methods are called. You can set the current file-system by calling `FileSystem.setFileSystem()`. During testing you can call the helper function `initMockFileSystem(os)` which takes a string name of the OS to emulate, and will also monkey-patch aspects of the TypeScript library to ensure that TS is also using the current file-system. Finally there is the `NgtscCompilerHost` to be used for any TypeScript compilation, which uses a given file-system. All tests that interact with the file-system should be tested against each of the mock file-systems. A series of helpers have been provided to support such tests: * `runInEachFileSystem()` - wrap your tests in this helper to run all the wrapped tests in each of the mock file-systems. * `addTestFilesToFileSystem()` - use this to add files and their contents to the mock file system for testing. * `loadTestFilesFromDisk()` - use this to load a mirror image of files on disk into the in-memory mock file-system. * `loadFakeCore()` - use this to load a fake version of `@angular/core` into the mock file-system. All ngcc and ngtsc source and tests now use this virtual file-system setup. PR Close #30921
