From 4ddc4a3e3129401f43d2f147f08b250b8afce792 Mon Sep 17 00:00:00 2001 From: Joe Date: Thu, 12 Mar 2026 16:35:44 -0500 Subject: [PATCH 01/16] feat: add .gitignore for logs and refactor ServeSession to include path_roots in init_tree return - Introduced a new .gitignore file to exclude log files from version control. - Modified the `init_tree` function in `ServeSession` to return `path_roots`, enhancing the function's utility. - Cleaned up commented-out code in `sourcemap.rs`, `patch_apply.rs`, and `tree.rs` for better readability and maintainability. --- .cursor/.gitignore | 1 + src/cli/sourcemap.rs | 2 - src/serve_session.rs | 79 ++++++++++++------------------------- src/snapshot/patch_apply.rs | 5 --- src/snapshot/tree.rs | 23 +++++------ 5 files changed, 36 insertions(+), 74 deletions(-) create mode 100644 .cursor/.gitignore diff --git a/.cursor/.gitignore b/.cursor/.gitignore new file mode 100644 index 00000000..df1a13b2 --- /dev/null +++ b/.cursor/.gitignore @@ -0,0 +1 @@ +/logs \ No newline at end of file diff --git a/src/cli/sourcemap.rs b/src/cli/sourcemap.rs index 45db803c..64143b06 100644 --- a/src/cli/sourcemap.rs +++ b/src/cli/sourcemap.rs @@ -88,8 +88,6 @@ impl SourcemapCommand { filter_non_scripts }; - // Pre-build a rayon threadpool with a low number of threads to avoid - // dynamic creation overhead on systems with a high number of cpus. rayon::ThreadPoolBuilder::new() .num_threads(num_cpus::get().min(6)) .build_global() diff --git a/src/serve_session.rs b/src/serve_session.rs index 50212629..b69f6cc9 100644 --- a/src/serve_session.rs +++ b/src/serve_session.rs @@ -17,7 +17,7 @@ use crate::{ session_id::SessionId, snapshot::{ apply_patch_set, compute_patch_set, AppliedPatchSet, InstanceContext, InstanceSnapshot, - PatchSet, PathIgnoreRule, RojoTree, + PatchSet, RojoTree, }, snapshot_middleware::{is_script_relevant_path, snapshot_from_vfs, INIT_FILE_PRIORITY}, }; @@ -330,7 +330,8 @@ impl ServeSession { fn init_tree( vfs: &Vfs, start_path: &Path, - ) -> Result<(Project, RojoTree, Option>), ServeSessionError> { + ) -> Result<(Project, RojoTree, Option>, Vec), ServeSessionError> + { log::trace!("Starting new ServeSession at path {}", start_path.display()); let root_project = Project::load_initial_project(vfs, start_path)?; @@ -421,69 +422,39 @@ impl ServeSession { vfs.clear_prefetch_cache(); let patch_start = Instant::now(); - let watch_ignore_rules = root_project.path_ignore_rules(); - std::thread::scope(|s| { - s.spawn(|| { - use walkdir::WalkDir; - let watch_start = Instant::now(); - let mut watch_count: usize = 0; - - if cfg!(target_os = "macos") { - // macOS kqueue: one FD per watched path.

FSEvents provides complete event kinds (Create/Remove/Modify) without needing a file cache, avoiding the debouncer-full's Create+Remove cancellation bug. Windows/Linux: notify-debouncer-full with RecommendedCache. RDCW needs the file cache to detect cross-directory moves and renames. The cache also handles RDCW's limited event granularity. Both platforms share the same convert_event logic for mapping notify EventKinds to VfsEvents.
