From 7b4ad20805a31b7fee81e0e24810034af423345d Mon Sep 17 00:00:00 2001 From: thatsatechnique <28403172+thatsatechnique@users.noreply.github.com> Date: Thu, 5 Mar 2026 16:32:31 -0800 Subject: [PATCH] =?UTF-8?q?fix(ook):=20address=20upstream=20PR=20review=20?= =?UTF-8?q?=E2=80=94=20SDR=20tracking,=20validation,=20cleanup,=20XSS?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Critical: - Pass sdr_type_str to claim/release_sdr_device (was missing 3rd arg) - Add ook_active_sdr_type module-level var for proper device registry tracking - Add server-side range validation on all timing params via validate_positive_int Major: - Extract cleanup_ook() function for full teardown (stop_event, pipes, process, SDR release) — called from both stop_ook() and kill_all() - Replace Popen monkey-patching with module-level _ook_stop_event/_ook_parser_thread - Fix XSS: define local _esc() fallback in ook.js, never use raw innerHTML - Remove dead inversion code path in utils/ook.py (bytes.fromhex on same string that already failed decode — could never produce a result) Minor: - Status event key 'status' → 'text' for consistency with other modules - Parser thread logging: debug → warning for missing code field and errors - Parser thread emits status:stopped on exit (normal EOF or crash) - Add cache-busting ?v={{ version }}&r=ook1 to ook.js script include - Fix gain/ppm comparison: != '0' (string) → != 0 (number) Tests: 22 → 33 (added start success, stop with process, SSE stream, timing range validation, stopped-on-exit event) Co-Authored-By: Claude Opus 4.6 --- app.py | 14 +++-- routes/ook.py | 137 +++++++++++++++++++++++++---------------- static/js/modes/ook.js | 11 +++- templates/index.html | 2 +- tests/test_ook.py | 111 ++++++++++++++++++++++++++++++++- utils/ook.py | 34 ++++------ 6 files changed, 224 insertions(+), 85 deletions(-) diff --git a/app.py b/app.py index 0c2c7f0..f87ff79 100644 --- a/app.py +++ b/app.py @@ -896,12 +896,16 @@ def kill_all() -> Response: with morse_lock: morse_process = None -
