- Introduced `is_watch_enabled` method to check the status of automatic file watching in the VFS.
- Added a new test for prefetch cache to validate metadata retrieval and error handling for walked roots and external paths.
- Updated the `watch` method in `StdBackend` for cleaner logic.
- Enhanced the `dir_init` field in `PrefetchCache` to store resolved init-file information for directories, improving prefetch operations.
- Modified the `watch` method in `StdBackend` to allow upgrading a non-recursive watch to a recursive one, improving flexibility in file watching.
- Added a new test to verify that a non-recursive watch can be upgraded to recursive, ensuring correct behavior in directory watching scenarios.
These changes aim to enhance the VFS's ability to manage file system events more effectively.
- Updated the `watch` method in `VfsBackend` to accept a `recursive` parameter, allowing for more flexible directory watching.
- Implemented a recording mode in the `Vfs` struct to track accessed paths without immediately watching them, improving performance during read operations.
- Added tests to verify the behavior of the new recording mode and ensure correct path tracking.
- Enhanced the `StdBackend` and `NoopBackend` implementations to support the updated watch functionality.
These changes aim to improve the VFS's ability to manage file system events and enhance user control over watching behavior.
- Eliminated the `canonicalize` method from the `VfsBackend` trait and its implementations in `InMemoryFs`, `NoopBackend`, and `StdBackend`, simplifying the interface and reducing complexity.
- Updated various parts of the codebase to remove references to canonicalization, including tests and prefetch cache handling, ensuring consistency across the project.
- Adjusted logging and comments to reflect the removal of path normalization logic, enhancing clarity and maintainability.
These changes aim to streamline the VFS implementation by focusing on core functionalities without the overhead of path canonicalization.
- Added a check for `watch_enabled` before calling `unwatch` in the `remove_file` and `remove_dir_all` methods to prevent unnecessary operations when watching is disabled.
- Updated error handling in the `StdBackend` to include a new condition for `Generic` errors related to watch status, improving logging clarity.
These changes aim to optimize the file system operations and enhance error handling in the virtual file system.
- Changed several logging statements from `info` to `debug` across various modules, including `StdBackend`, `RefPathIndex`, `ServeSession`, and `syncback_loop_with_stats`.
- This adjustment aims to reduce log verbosity during normal operations while retaining detailed logs for debugging purposes, enhancing overall performance and maintainability.
- Added a `children` field to the `PrefetchCache` structure to store sorted child paths for directories, optimizing directory read operations.
- Updated the `read_dir` method in `VfsInner` to utilize the new `children` cache, improving performance by reducing backend calls for cached directories.
- Refactored the `prefetch_project_files` function to populate the `children` map during prefetching, enhancing the efficiency of path collection.
- Adjusted tests to accommodate the new `children` field in `PrefetchCache`, ensuring comprehensive coverage of the updated functionality.
These changes aim to improve the performance and reliability of the VFS by refining the prefetching mechanism and enhancing directory handling.
- Introduced new scripts for auto-fixing formatting and performing static analysis across the project, including support for Lua, Rust, and TypeScript.
- Created `format.md` documentation to guide users on running the formatting scripts.
- Updated CI scripts to utilize the number of processor threads for improved performance during linting and testing.
- Enhanced logging in the `unwatch` function to provide clearer feedback on path watching status.
These changes streamline the formatting and analysis process, ensuring consistent code quality across the project.
- Updated the `new` method in `StdBackend` to improve error handling for file watching.
- Introduced specific handling for `WatcherCriticalError::RescanRequired`, allowing the watcher to recover from rapid changes while logging a warning.
- Ensured that all other critical errors will terminate the process, maintaining reliability in file watching operations.
- Updated the `StdBackend` to utilize `notify::RecommendedWatcher` instead of a platform-specific watcher type, enhancing cross-platform event delivery.
- Simplified the debouncer initialization by removing platform-specific configurations, streamlining the code for better maintainability.
- Improved documentation to reflect changes in the watcher implementation and clarify the debouncing mechanism.
- Updated the `StdBackend` to use a platform-specific watcher type, enhancing event delivery on macOS by utilizing `PollWatcher`.
- Refactored the path suppression logic in `JobThreadContext` to handle any VFS event type, improving the accuracy of event processing during renames and writes.
- Enhanced documentation to clarify the changes in event handling and suppression mechanisms, contributing to better maintainability and understanding of the code.
- Update notify dependency from 4.0.18 to 8.2
- Add notify-debouncer-full 0.7 for event debouncing
- Rewrite StdBackend to use new debouncer API and EventKind system
- Add 13 stress tests including undo/redo simulation
