From 31aa6707080ee12c907138f25081b530f1abd3bc Mon Sep 17 00:00:00 2001 From: AI Agent Bot Date: Sat, 21 Feb 2026 06:42:21 -0600 Subject: [PATCH 1/2] Comprehensive safety, validation, testing, and DX improvements - Replace std::sync::Mutex/RwLock with parking_lot across IPC, daemon, and video player code to eliminate mutex poisoning panics (Phase 1a) - Replace expect() in FFmpeg init with OnceLock error propagation (Phase 1d) - Add Validate trait with NaN/Inf, string length, and data size checks for all protocol message types (Phase 2a) - Add video source URL validation in both daemons (Phase 2b) - Add MAX_FRAME_DIMENSION bounds check in itk-shmem (Phase 2c) - Add 48 new tests: adversarial protocol tests, itk-net coverage, IPC integration tests, and itk-sync edge cases (Phase 3) - Add Justfile, elevate clippy lints to deny, add tracing to core crates, and clean up disabled CI workflows (Phase 4) - Migrate itk-protocol from bincode to bitcode with VERSION bump (Phase 5a) - Add seqlock writer-count runtime check (Phase 5c) - Add daemon health-check ping/pong in launcher (Phase 5d) Co-Authored-By: Claude Opus 4.6 --- .github/workflows/pr-validation.yml | 341 +------------ Cargo.lock | 39 +- Cargo.toml | 11 +- Justfile | 52 ++ core/itk-ipc/Cargo.toml | 1 + core/itk-ipc/src/lib.rs | 87 ++++ core/itk-ipc/src/unix_impl.rs | 24 +- core/itk-ipc/src/windows_impl.rs | 18 +- core/itk-net/src/discovery.rs | 58 +++ core/itk-net/src/peer.rs | 82 +++ core/itk-net/src/sync_manager.rs | 128 +++++ core/itk-protocol/Cargo.toml | 3 +- core/itk-protocol/src/lib.rs | 475 +++++++++++++++++- core/itk-shmem/Cargo.toml | 1 + core/itk-shmem/src/lib.rs | 37 +- core/itk-sync/src/lib.rs | 213 ++++++++ core/itk-video/src/decoder.rs | 23 +- daemon/Cargo.toml | 1 + daemon/src/main.rs | 52 +- daemon/src/video/player.rs | 29 +- deny.toml | 6 +- projects/nms-cockpit-video/daemon/Cargo.toml | 3 + projects/nms-cockpit-video/daemon/src/main.rs | 50 +- .../daemon/src/video/player.rs | 16 +- .../nms-cockpit-video/launcher/Cargo.toml | 2 + .../nms-cockpit-video/launcher/src/main.rs | 67 +++ 26 files changed, 1379 insertions(+), 440 deletions(-) create mode 100644 Justfile diff --git a/.github/workflows/pr-validation.yml b/.github/workflows/pr-validation.yml index 9180f8a..ab3e8bb 100644 --- a/.github/workflows/pr-validation.yml +++ b/.github/workflows/pr-validation.yml @@ -91,344 +91,10 @@ jobs: fi done - # -- Gemini AI Code Review ----------------------------------------------- - # DISABLED: AI reviews will be enabled in a future iteration. - gemini-review: - name: Gemini AI Code Review - needs: fork-guard - if: false # disabled until AI review pipeline is ready - runs-on: self-hosted - timeout-minutes: 30 - outputs: - status: ${{ steps.review.outputs.status }} - steps: - - name: Pre-checkout cleanup - run: | - for item in outputs target .git/index.lock; do - if [ -d "$item" ] || [ -f "$item" ]; then - docker run --rm -v "$(pwd):/workspace" busybox:1.36.1 sh -c \ - "rm -rf /workspace/$item" 2>/dev/null || \ - sudo rm -rf "$item" 2>/dev/null || true - fi - done - - - name: Checkout - uses: actions/checkout@v4 - with: - fetch-depth: 0 - clean: true - token: ${{ secrets.GITHUB_TOKEN }} - ref: ${{ github.head_ref }} - - - name: Log commit info - id: check-agent - run: | - LAST_AUTHOR=$(git log -1 --format='%an') - echo "Last commit author: $LAST_AUTHOR" - IS_AGENT="false" - if [[ "$LAST_AUTHOR" == "AI Review Agent" ]] || \ - [[ "$LAST_AUTHOR" == "AI Pipeline Agent" ]] || \ - [[ "$LAST_AUTHOR" == "AI Agent Bot" ]]; then - IS_AGENT="true" - fi - echo "is_agent_commit=$IS_AGENT" >> $GITHUB_OUTPUT - - - name: Run Gemini review - id: review - env: - GOOGLE_API_KEY: ${{ secrets.GOOGLE_API_KEY }} - GEMINI_API_KEY: ${{ secrets.GEMINI_API_KEY }} - GH_TOKEN: ${{ secrets.GITHUB_TOKEN }} - PR_NUMBER: ${{ github.event.pull_request.number }} - run: | - if ! command -v github-agents &>/dev/null; then - echo "::warning::github-agents not found on PATH - skipping Gemini review" - echo "status=skipped" >> $GITHUB_OUTPUT - exit 0 - fi - - set +e - OUTPUT=$(github-agents pr-review "$PR_NUMBER" --editor 2>&1) - EXIT_CODE=$?
