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

fix(ivy): support abstract directives in template type checking (#33131) Recently it was made possible to have a directive without selector, which are referred to as abstract directives. Such directives should not be registered in an NgModule, but can still contain decorators for inputs, outputs, queries, etc. The information from these decorators and the `@Directive()` decorator itself needs to be registered with the central `MetadataRegistry` so that other areas of the compiler can request information about a given directive, an example of which is the template type checker that needs to know about the inputs and outputs of directives. Prior to this change, however, abstract directives would only register themselves with the `MetadataRegistry` as being an abstract directive, without all of its other metadata like inputs and outputs. This meant that the template type checker was unable to resolve the inputs and outputs of these abstract directives, therefore failing to check them correctly. The typical error would be that some property does not exist on a DOM element, whereas said property should have been bound to the abstract directive's input. This commit fixes the problem by always registering the metadata of a directive or component with the `MetadataRegistry`. Tests have been added to ensure abstract directives are handled correctly in the template type checker, together with tests to verify the form of abstract directives in declaration files.

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.

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.

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): 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(ivy): don't track identifiers of ffr-resolved references (#29387) This fix is for a bug in the ngtsc PartialEvaluator, which statically evaluates expressions. Sometimes, evaluating a reference requires resolving a function which is declared in another module, and thus no function body is available. To support this case, the PartialEvaluator has the concept of a foreign function resolver. This allows the interpretation of expressions like: const router = RouterModule.forRoot([]); even though the definition of the 'forRoot' function has no body. In ngtsc today, this will be resolved to a Reference to RouterModule itself, via the ModuleWithProviders foreign function resolver. However, the PartialEvaluator also associates any Identifiers in the path of this resolution with the Reference. This is done so that if the user writes const x = imported.y; 'x' can be generated as a local identifier instead of adding an import for 'y'. This was at the heart of a bug. In the above case with 'router', the PartialEvaluator added the identifier 'router' to the Reference generated (through FFR) to RouterModule. This is not correct. References that result from FFR expressions may not have the same value at runtime as they do at compile time (indeed, this is not the case for ModuleWithProviders). The Reference generated via FFR is "synthetic" in the sense that it's constructed based on a useful interpretation of the code, not an accurate representation of the runtime value. Therefore, it may not be legal to refer to the Reference via the 'router' identifier.

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

fix(ivy): don't track identifiers of ffr-resolved references (#29387) This fix is for a bug in the ngtsc PartialEvaluator, which statically evaluates expressions. Sometimes, evaluating a reference requires resolving a function which is declared in another module, and thus no function body is available. To support this case, the PartialEvaluator has the concept of a foreign function resolver. This allows the interpretation of expressions like: const router = RouterModule.forRoot([]); even though the definition of the 'forRoot' function has no body. In ngtsc today, this will be resolved to a Reference to RouterModule itself, via the ModuleWithProviders foreign function resolver. However, the PartialEvaluator also associates any Identifiers in the path of this resolution with the Reference. This is done so that if the user writes const x = imported.y; 'x' can be generated as a local identifier instead of adding an import for 'y'. This was at the heart of a bug. In the above case with 'router', the PartialEvaluator added the identifier 'router' to the Reference generated (through FFR) to RouterModule. This is not correct. References that result from FFR expressions may not have the same value at runtime as they do at compile time (indeed, this is not the case for ModuleWithProviders). The Reference generated via FFR is "synthetic" in the sense that it's constructed based on a useful interpretation of the code, not an accurate representation of the runtime value. Therefore, it may not be legal to refer to the Reference via the 'router' identifier.

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(ivy): unable to import shim factory files on case-insensitive platforms (#28831) This change is kind of similar to #27466, but instead of ensuring that these shims can be generated, we also need to make sure that developers are able to also use the factory shims like with `ngc`. This issue is now surfacing because we have various old examples which are now also built with `ngtsc` (due to the bazel migration). On case insensitive platforms (e.g. windows) these examples cannot be built because ngtsc fails the app imports a generated shim file (such as the factory shim files). This is because the `GeneratedShimsHostWrapper` TypeScript host uses the `getCanonicalFileName` method in order to check whether a given file/module exists in the generator file maps. e.g. ``` // Generator Map: 'C:/users/paul/_bazel_paul/lm3s4mgv/execroot/angular/packages/core/index.ngfactory.ts' => 'C:/users/paul/_bazel_paul/lm3s4mgv/execroot/angular/packages/core/index.ts', // Path passed into `fileExists` C:/users/paul/_bazel_paul/lm3s4mgv/execroot/angular/packages/core/index.ngfactory.ts // After getCanonicalFileName (notice the **lower-case drive name**) c:/users/paul/_bazel_paul/lm3s4mgv/execroot/angular/packages/core/index.ngfactory.ts ``` As seen above, the generator map does not use the canonical file names, as well as TypeScript internally does not pass around canonical file names.

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(ivy): track cyclic imports that are added (#29040) ngtsc has cyclic import detection, to determine when adding an import to a directive or pipe would create a cycle. However, this detection must also account for already inserted imports, as it's possible for both directions of a circular import to be inserted by Ivy (as opposed to at least one of those edges existing in the user's program). This commit fixes the circular import detection for components to take into consideration already added edges. This is difficult for one critical reason: only edges to files which will *actually* be imported should be considered. However, that depends on which directives & pipes are used in a given template, which is currently only known by running the TemplateDefinitionBuilder during the 'compile' phase. This is too late; the decision whether to use remote scoping (which consults the import graph) is made during the 'resolve' phase, before any compilation has taken place. Thus, the only way to correctly consider synthetic edges is for the compiler to know exactly which directives & pipes are used in a template during 'resolve'. There are two ways to achieve this: 1) refactor `TemplateDefinitionBuilder` to do its work in two phases, with directive matching occurring as a separate step which can be performed earlier. 2) use the `R3TargetBinder` in the 'resolve' phase to independently bind the template and get information about used directives. Option 1 is ideal, but option 2 is currently used for practical reasons. The cost of binding the template can be shared with template-typechecking. PR Close #29040

fix(ivy): track cyclic imports that are added (#29040) ngtsc has cyclic import detection, to determine when adding an import to a directive or pipe would create a cycle. However, this detection must also account for already inserted imports, as it's possible for both directions of a circular import to be inserted by Ivy (as opposed to at least one of those edges existing in the user's program). This commit fixes the circular import detection for components to take into consideration already added edges. This is difficult for one critical reason: only edges to files which will *actually* be imported should be considered. However, that depends on which directives & pipes are used in a given template, which is currently only known by running the TemplateDefinitionBuilder during the 'compile' phase. This is too late; the decision whether to use remote scoping (which consults the import graph) is made during the 'resolve' phase, before any compilation has taken place. Thus, the only way to correctly consider synthetic edges is for the compiler to know exactly which directives & pipes are used in a template during 'resolve'. There are two ways to achieve this: 1) refactor `TemplateDefinitionBuilder` to do its work in two phases, with directive matching occurring as a separate step which can be performed earlier. 2) use the `R3TargetBinder` in the 'resolve' phase to independently bind the template and get information about used directives. Option 1 is ideal, but option 2 is currently used for practical reasons. The cost of binding the template can be shared with template-typechecking. PR Close #29040

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.

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.

feat(ivy): enable re-export of the compilation scope of NgModules privately (#33177) This commit refactors the aliasing system to support multiple different AliasingHost implementations, which control specific aliasing behavior in ngtsc (see the README.md). A new host is introduced, the `PrivateExportAliasingHost`. This solves a longstanding problem in ngtsc regarding support for "monorepo" style private libraries. These are libraries which are compiled separately from the main application, and depended upon through TypeScript path mappings. Such libraries are frequently not in the Angular Package Format and do not have entrypoints, but rather make use of deep import style module specifiers. This can cause issues with ngtsc's ability to import a directive given the module specifier of its NgModule. For example, if the application uses a directive `Foo` from such a library `foo`, the user might write: ```typescript import {FooModule} from 'foo/module'; ``` In this case, foo/module.d.ts is path-mapped into the program. Ordinarily the compiler would see this as an absolute module specifier, and assume that the `Foo` directive can be imported from the same specifier. For such non- APF libraries, this assumption fails. Really `Foo` should be imported from the file which declares it, but there are two problems with this: 1. The compiler would have to reverse the path mapping in order to determine a path-mapped path to the file (maybe foo/dir.d.ts). 2. There is no guarantee that the file containing the directive is path- mapped in the program at all. The compiler would effectively have to "guess" 'foo/dir' as a module specifier, which may or may not be accurate depending on how the library and path mapping are set up. It's strongly desirable that the compiler not break its current invariant that the module specifier given by the user for the NgModule is always the module specifier from which directives/pipes are imported. Thus, for any given NgModule from a particular module specifier, it must always be possible to import any directives/pipes from the same specifier, no matter how it's packaged. To make this possible, when compiling a file containing an NgModule, ngtsc will automatically add re-exports for any directives/pipes not yet exported by the user, with a name of the form: ɵngExportɵModuleNameɵDirectiveName This has several effects: 1. It guarantees anyone depending on the NgModule will be able to import its directives/pipes from the same specifier. 2. It maintains a stable name for the exported symbol that is safe to depend on from code on NPM. Effectively, this private exported name will be a part of the package's .d.ts API, and cannot be changed in a non-breaking fashion. Fixes #29361 FW-1610 #resolve PR Close #33177

For example, if the application uses a directive `Foo` from such a library `foo`, the user might write: ```typescript import {FooModule} from 'foo/module'; ``` In this case, foo/module.d.ts is path-mapped into the program. Ordinarily the compiler would see this as an absolute module specifier, and assume that the `Foo` directive can be imported from the same specifier. For such non- APF libraries, this assumption fails. Really `Foo` should be imported from the file which declares it, but there are two problems with this: 1. The compiler would have to reverse the path mapping in order to determine a path-mapped path to the file (maybe foo/dir.d.ts). 2. There is no guarantee that the file containing the directive is path- mapped in the program at all. The compiler would effectively have to "guess" 'foo/dir' as a module specifier, which may or may not be accurate depending on how the library and path mapping are set up. It's strongly desirable that the compiler not break its current invariant that the module specifier given by the user for the NgModule is always the module specifier from which directives/pipes are imported. Thus, for any given NgModule from a particular module specifier, it must always be possible to import any directives/pipes from the same specifier, no matter how it's packaged. To make this possible, when compiling a file containing an NgModule, ngtsc will automatically add re-exports for any directives/pipes not yet exported by the user, with a name of the form: ɵngExportɵModuleNameɵDirectiveName This has several effects: 1. It guarantees anyone depending on the NgModule will be able to import its directives/pipes from the same specifier. 2. It maintains a stable name for the exported symbol that is safe to depend on from code on NPM.

Such libraries are frequently not in the Angular Package Format and do not have entrypoints, but rather make use of deep import style module specifiers. This can cause issues with ngtsc's ability to import a directive given the module specifier of its NgModule. For example, if the application uses a directive `Foo` from such a library `foo`, the user might write: ```typescript import {FooModule} from 'foo/module'; ``` In this case, foo/module.d.ts is path-mapped into the program. Ordinarily the compiler would see this as an absolute module specifier, and assume that the `Foo` directive can be imported from the same specifier. For such non- APF libraries, this assumption fails. Really `Foo` should be imported from the file which declares it, but there are two problems with this: 1. The compiler would have to reverse the path mapping in order to determine a path-mapped path to the file (maybe foo/dir.d.ts). 2. There is no guarantee that the file containing the directive is path- mapped in the program at all. The compiler would effectively have to "guess" 'foo/dir' as a module specifier, which may or may not be accurate depending on how the library and path mapping are set up. It's strongly desirable that the compiler not break its current invariant that the module specifier given by the user for the NgModule is always the module specifier from which directives/pipes are imported. Thus, for any given NgModule from a particular module specifier, it must always be possible to import any directives/pipes from the same specifier, no matter how it's packaged. To make this possible, when compiling a file containing an NgModule, ngtsc will automatically add re-exports for any directives/pipes not yet exported by the user, with a name of the form: ɵngExportɵModuleNameɵDirectiveName This has several effects: 1. It guarantees anyone depending on the NgModule will be able to import its directives/pipes from the same specifier. 2. It maintains a stable name for the exported symbol that is safe to depend on from code on NPM. Effectively, this private exported name will be a part of the package's .d.ts API, and cannot be changed in a non-breaking fashion. Fixes #29361 FW-1610 #resolve PR Close #33177

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.

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.

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.

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.

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.
