# Changelog

## 2025-12-08 - 6.1.1 - fix(watchers/watcher.node)
Improve Node watcher robustness: inode tracking, ENOSPC detection, enhanced health checks and temp-file handling

- Track directory inodes (watchedInodes) and restart watchers if inode changes are detected (addresses stale watchers when directories are replaced).
- Health check now validates inode stability and explicitly detects ENOSPC (inotify max_user_watches) errors, emitting errors and logging a recommended fix command.
- Detect ENOSPC in FSWatcher error events and log guidance to increase inotify limits.
- Clear inode tracking state on watcher stop to avoid stale state across restarts.
- Improve temporary file handling and logging to avoid dropping events for atomic writes (only skip pure temp files and log skipped temp events).
- Documentation (readme.hints.md) updated with robustness notes, known fs.watch limitations, and example logs.

## 2025-12-08 - 6.1.0 - feat(watcher.node)
Add automatic restart, periodic health checks, and safe event emission to Node watcher; improve logging and stat handling

- NodeWatcher: introduced safeEmit() to isolate subscriber errors and prevent watcher crashes
- Auto-restart on failure with exponential backoff (1s → 30s) and up to 3 retry attempts per watched base path
- Periodic health checks (every 30s) to detect missing watched paths and trigger automatic restarts
- Handle unexpected FSWatcher 'close' events and restart watchers when they close silently
- Verbose lifecycle logging with `[smartwatch]` prefix for start/stop/health/restart events
- Clear restart tracking and stop health checks on watcher.stop() to ensure clean shutdown
- Improved statSafe() to normalize followSymlinks logic and log non-ENO errors as warnings
- Updated readme.hints.md documenting the new robustness features (v6.1.0+)

## 2025-12-08 - 6.0.0 - BREAKING CHANGE(watchers)
Replace polling-based write stabilization with debounce-based event coalescing and simplify watcher options

- Remove polling-based WriteStabilizer (ts/utils/write-stabilizer.ts) and related waitForWriteFinish logic
- Introduce debounce-based coalescing (debounceMs) for Node and Deno watchers (ts/watchers/watcher.node.ts, ts/watchers/watcher.deno.ts)
- Change IWatcherOptions: remove stabilityThreshold/pollInterval/maxWaitTime and add debounceMs
- Default watcher options updated to use debounceMs = 100
- Node/Deno watchers now skip editor temp files earlier, debounce duplicate events, and emit events directly (no size polling)
- Updated default watcher creation in Smartwatch to pass debounceMs
- Update package.json build script to run 'tsbuild tsfolders'

## 2025-12-08 - 5.1.0 - feat(watchers)
Improve write stabilization and ignore temporary editor files

- Add maxWaitTime option (ms) to IWatcherOptions and WriteStabilizer to cap how long stabilization will wait (default: 1000ms).
- WriteStabilizer: reduce default stabilityThreshold from 300ms to 100ms and track write start time to enforce maxWaitTime and avoid indefinite polling.
- Node and Deno watchers: detect and ignore common temporary/editor files (e.g. *.tmp.*, *.swp, *.swx, trailing ~, .#*) to prevent spurious events from atomic saves.
- Node watcher: treat rename (atomic-save) events as already-complete files and emit add/change immediately without stabilization.
- Deno watcher: use the configured maxWaitTime and polling-based stabilization for modify events to ensure consistent behavior across runtimes.

## 2025-11-30 - 5.0.0 - BREAKING CHANGE(@push.rocks/smartwatch)
Rename package and update branding/docs: switch from @push.rocks/smartchok to @push.rocks/smartwatch, update repository/homepage/bugs URLs and author, and refresh README examples and install instructions.

- Package name changed from @push.rocks/smartchok to @push.rocks/smartwatch in package.json
- Repository, homepage and issue URLs updated to point to the new smartwatch repository
- Author changed to Task Venture Capital GmbH in package metadata

## 2025-11-30 - 4.0.1 - fix(readme)
Update README: refine description and clarify trademark/legal information

- Refined project description and tagline for clarity and brevity (adds lightweight wording and an emoji).
- Updated Trademark section to explicitly mention third-party trademarks, add guidance about usage and approval, and clarify that trademarks are not covered by the MIT license.
- Minor legal/company wording and formatting fixes (e.g. 'District Court' capitalization and contact sentence tweaks).
- General README wording and formatting improvements for clearer instructions and feature descriptions.

## 2025-11-30 - 4.0.0 - BREAKING CHANGE(watchers)
Replace chokidar with native platform watchers and add cross-runtime support (Node.js, Deno, Bun); introduce write stabilization and internal glob matching

- Replaced chokidar-based implementation with native file watching APIs (Node.js fs.watch, Deno.watchFs).
- Added platform-specific watchers: NodeWatcher and DenoWatcher (Bun uses Node compatibility).
- Implemented polling-based write stabilization (awaitWriteFinish replacement) to avoid duplicate events during writes.
- Keep glob pattern support by matching events internally using picomatch; base-path extraction used to limit watch scope.
- API/runtime requirement increased: Node.js >= 20.0.0 is required for native recursive fs.watch.
- Package/documentation name and examples updated to @push.rocks/smartchok and export the Smartwatch class.

## 2025-11-30 - 3.0.0 - BREAKING CHANGE(smartwatch)
Introduce Smartwatch: cross-runtime native file watching for Node.js, Deno and Bun; rename smartchok to smartwatch and bump major version to 2.0.0

- Rename public API and docs from Smartchok to Smartwatch and update package metadata for the new module name.
- Replace chokidar with native watchers and picomatch-based glob filtering to enable cross-runtime support (Node.js, Deno, Bun).
- Add watcher factory and runtime-specific implementations: watchers/index.ts, watcher.node.ts, watcher.deno.ts.
- Add WriteStabilizer (ts/utils/write-stabilizer.ts) to provide awaitWriteFinish functionality via polling.
- Introduce @push.rocks/smartenv for runtime detection and remove direct chokidar dependency; update dependencies accordingly.
- Update tests (test/test.ts) and documentation (readme.md, readme.hints.md) to reflect API/name changes and new architecture.
- Bump package version to 2.0.0 to mark breaking changes in API and behavior.

## 2025-11-29 - 1.2.0 - feat(core)
Migrate to chokidar 5.x, add picomatch filtering and update test/dev dependencies

- Upgrade runtime dependencies: chokidar -> ^5.0.0 and picomatch -> ^4.0.3; bumped related @push.rocks packages versions.
- Upgrade devDependencies: @git.zone/tsbuild, @git.zone/tsrun and @git.zone/tstest to newer v2/v3 releases; updated @types/node.
- Updated README and readme.hints to document migration to chokidar 5.x and dev dependency changes.
- Tests updated to use @git.zone/tstest/tapbundle (import change) and test runner start changed to export default tap.start().
- Smartchok implementation updated to extract glob base paths, watch base directories and filter events via picomatch matchers (shouldWatchPath + event filtering).
- Note: ts/00_commitinfo_data.ts still references chokidar 4.x in the description and should be updated to reflect the migration.

## 2025-06-26 - 1.1.1 - fix(package.json)
Add packageManager field to package.json for pnpm configuration

- Added "packageManager": "pnpm@10.11.0+sha512.6540583f41cc5f628eb3d9773ecee802f4f9ef9923cc45b69890fb47991d4b092964694ec3a4f738a420c918a333062c8b925d312f42e4f0c263eb603551f977" to package.json

## 2025-06-26 - 1.1.0 - feat(Smartchok)

- Removed deprecated @tempfix/watcher and added chokidar and picomatch as dependencies in package.json
- Updated Smartchok class to extract base paths and apply custom glob filtering using picomatch
- Revised readme and technical hints to reflect migration to chokidar 4.x and clarify glob pattern support
