v0.1.0

Net Flow v0.1.0

Added

• Native Windows 11 Widgets Board Integration:
  • Full support for Small, Medium, and Large card sizes using Adaptive Cards v1.6.
  • Interactive in-card settings for speed units (Auto-scaled, Bytes/s, KB/s, MB/s, Gbps) and timeframes (15s, 30s, 60s, 120s).
• Dual-Stream Telemetry Waveforms:
  • In-memory supersampled rasteriser rendering mirrored sparklines on a shared scale (cyan download above baseline, amber upload below).
  • Anti-aliased area gradient fills and glowing live pulse indicator nodes.
  • 50 KB/s scale floor (MIN_CHART_SCALE_BPS) keeping sub-kilobyte background noise proportional.
  • 18% vertical headroom preventing peak traffic spikes from touching card boundaries.
• Active App Bandwidth Attribution:
  • Per-process network throughput monitoring combining socket tracking and I/O heuristics.
  • Compact right-column rate notation with shared bandwidth units (↓ 11.1 ↑ 9.1 KB/s (37)).
  • Generous 22-character application name budget on Medium and Large cards to prevent truncation.
• Smart Interface Detection:
  • Auto-detection of primary active network interface (Wi-Fi, Ethernet, Cellular, VPN).
  • Safe Wi-Fi SSID resolution via Windows Native Wi-Fi API (wlanapi.dll) with graceful fallback.
• Session Telemetry & Persistence:
  • Cumulative upload/download session counters and elapsed duration tracking.
  • Inline Reset action directly on the card to reset session statistics.
  • Local session state persistence across reboots in %LocalAppData%.
• High-Performance Release Profile:
  • Configured [profile.release] with opt-level = 3, lto = true, codegen-units = 1, strip = true, and panic = "abort".
  • Achieved a compact 1.24 MB standalone release binary.
• Packaging & Publishing Pipeline:
  • Store-ready MSIX packaging pipeline for automated Microsoft Partner Center ingestion.
  • Automated GitHub Actions workflows for continuous integration (ci.yml), GitHub Releases (release.yml), and store publishing (store-publish.yml).
  • Single source of truth versioning automatically synchronized from Cargo.toml.
• Comprehensive Test Suite:
  • 75 automated unit tests covering bandwidth allocation math, history ring buffers, card templates, and lock poison recovery.
  • Strict zero-warning Clippy policy enforced across all workspace targets.

Changed

• Decoupled Process Sampling Cadence:
  • Separated heavy Win32 process queries (CreateToolhelp32Snapshot, GetProcessMemoryInfo) to a 1.0-second interval.
  • Maintained continuous 500ms polling for physical network interface throughput (GetIfTable2), eliminating system scheduler jitter and bandwidth scaling distortion.
• Lock Poison Resilience:
  • Implemented extension traits (LockExt, RwLockExt) providing .lock_safe(), .read_safe(), and .write_safe() across all mutexes and read-write locks.
  • Guarantees automatic poison recovery across worker threads under panic = "abort".
• COM Server Lifetime & Idle Shutdown:
  • Added idle monitoring loop with has_had_widgets tracking and a 30-second post-removal grace period.
  • Implemented graceful shutdown sequence: calls CoRevokeClassObject, terminates background worker thread, invokes CoUninitialize(), and cleanly exits to prevent zombie background processes.
• Eviction-Bounded Icon Cache:
  • Implemented a 256-entry capacity limit on ICON_CACHE in crates/core/src/process.rs to prevent memory growth during long-running sessions.
• Lossy Wi-Fi SSID Decoding:
  • Switched from strict UTF-8 decoding to String::from_utf8_lossy to safely handle non-standard SSID encodings without panicking.
• Thread-Safe Rotating Logging:
  • Synchronized file I/O under LOG_MUTEX.
  • Capped widget log size at 1 MB, automatically rotating netflow_widget.log to .old.
  • Throttled verbose 1Hz card generation ticks behind NETFLOW_VERBOSE_LOG=1.
