perf(ngcc): process tasks in parallel in async mode (#32427) `ngcc` supports both synchronous and asynchronous execution. The default mode when using `ngcc` programmatically (which is how `@angular/cli` is using it) is synchronous. When running `ngcc` from the command line (i.e. via the `ivy-ngcc` script), it runs in async mode. Previously, the work would be executed in the same way in both modes. This commit improves the performance of `ngcc` in async mode by processing tasks in parallel on multiple processes. It uses the Node.js built-in [`cluster` module](https://nodejs.org/api/cluster.html) to launch a cluster of Node.js processes and take advantage of multi-core systems. Preliminary comparisons indicate a 1.8x to 2.6x speed improvement when processing the angular.io app (apparently depending on the OS, number of available cores, system load, etc.). Further investigation is needed to better understand these numbers and identify potential areas of improvement.

refactor(ngcc): pass dependency info to `collectDependencies()` (#34494) Rather than return a new object of dependency info from calls to `collectDependencies()` we now pass in an object that will be updated with the dependency info. This is in preparation of a change where we will collect dependency information from more than one `DependencyHost`. Also to better fit with this approach the name is changed from `findDependencies()` to `collectDependencies()`. PR Close #34494

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(ngcc): capture entry-point dependencies from typings as well as source (#34494) ngcc computes a dependency graph of entry-points to ensure that entry-points are processed in the correct order. Previously only the imports in source files were analysed to determine the dependencies for each entry-point. This is not sufficient when an entry-point has a "type-only" dependency - for example only importing an interface from another entry-point. In this case the "type-only" import does not appear in the source code. It only appears in the typings files. This can cause a dependency to be missed on the entry-point. This commit fixes this by additionally processing the imports in the typings program, as well as the source program. Note that these missing dependencies could cause unexpected flakes when running ngcc in async mode on multiple processes due to the way that ngcc caches files when they are first read from disk.

fix(ngcc): capture entry-point dependencies from typings as well as source (#34494) ngcc computes a dependency graph of entry-points to ensure that entry-points are processed in the correct order. Previously only the imports in source files were analysed to determine the dependencies for each entry-point. This is not sufficient when an entry-point has a "type-only" dependency - for example only importing an interface from another entry-point. In this case the "type-only" import does not appear in the source code. It only appears in the typings files. This can cause a dependency to be missed on the entry-point. This commit fixes this by additionally processing the imports in the typings program, as well as the source program. Note that these missing dependencies could cause unexpected flakes when running ngcc in async mode on multiple processes due to the way that ngcc caches files when they are first read from disk.

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.

perf(ngcc): process tasks in parallel in async mode (#32427) `ngcc` supports both synchronous and asynchronous execution. The default mode when using `ngcc` programmatically (which is how `@angular/cli` is using it) is synchronous. When running `ngcc` from the command line (i.e. via the `ivy-ngcc` script), it runs in async mode. Previously, the work would be executed in the same way in both modes. This commit improves the performance of `ngcc` in async mode by processing tasks in parallel on multiple processes. It uses the Node.js built-in [`cluster` module](https://nodejs.org/api/cluster.html) to launch a cluster of Node.js processes and take advantage of multi-core systems. Preliminary comparisons indicate a 1.8x to 2.6x speed improvement when processing the angular.io app (apparently depending on the OS, number of available cores, system load, etc.).

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): ngcc - prevent crash when analyzed target is ignored (#31872) ngcc analyzes the dependency structure of the entrypoints it needs to process, as the compilation of entrypoints is ordering sensitive: any dependent upon entrypoint must be compiled before its dependees. As part of the analysis of the dependency graph, it is detected when a dependency of entrypoint is not installed, in which case that entrypoint will be marked as ignored. When a target entrypoint to compile is provided, it could occur that given target is considered ignored because one of its dependencies might be missing. This situation was not dealt with currently, instead resulting in a crash of ngcc. This commit prevents the crash by taking the above scenario into account. PR Close #31872

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(ngcc): pass dependency info to `collectDependencies()` (#34494) Rather than return a new object of dependency info from calls to `collectDependencies()` we now pass in an object that will be updated with the dependency info. This is in preparation of a change where we will collect dependency information from more than one `DependencyHost`. Also to better fit with this approach the name is changed from `findDependencies()` to `collectDependencies()`. PR Close #34494

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.
