Stop Scanner Enhancements -- **Modified**: `stopScanner()` function (~Line 1494) -- **Changes**: - - Re-enables device and region selectors after stopping - - Maintains UI consistency - -#### 5. Region Selector Sync -- **Modified**: `selectRegion()` function (~Line 1882) -- **Changes**: - - Capitalizes region name to match backend API expectations - - Syncs region button selection with dropdown - -#### 6.

Multiple Devices -```bash -# Connect multiple SDR devices -# Open GSM Spy dashboard -# Verify all devices appear in dropdown -# Select different devices and verify they work independently -``` - -### 4. UI State -```bash -# Start GSM scanner -# Verify device selector is disabled -# Verify region selector is disabled -# Stop scanner -# Verify both selectors are re-enabled -``` - -### 5.

start properly (S or R state, not Z) -# - Processes disappear when stopped (not left as zombies) -``` - -3. **Check process tree**: -```bash -pstree -p | grep grgsm -# Should show proper parent-child relationships -# No defunct/zombie entries -``` - -## Process Lifecycle - -### Normal Operation - -1. **Scanner Start**: - - `grgsm_scanner` spawned → stored in `gsm_spy_process` - - `scanner_thread` reads output - - Process running normally - -2. **Monitor Start** (auto or manual): - - `grgsm_livemon` spawned → stored in `gsm_spy_livemon_process` - - `tshark` spawned → stored in `gsm_spy_monitor_process` - - `monitor_thread` reads tshark output - - Both processes running normally - -3. **Stop**: - - All three processes terminated gracefully - - `wait()` called on each to collect exit status - - Process handles set to None - - No zombies remain - -### Error Handling - -1. **Process crashes during operation**: - - Thread's stdout loop exits - - `finally` block executes - - `process.wait()` collects exit status - - No zombie created - -2. **Process hangs**: - - `terminate()` called - - `wait(timeout=5)` gives 5 seconds to exit - - If timeout, `kill()` is called - - `wait()` collects exit status - -3. **Exception during cleanup**: - - Fallback to `kill()` + `wait()` - - Ensures zombie is always prevented - -## Best Practices Applied - -1. **Always reap child processes**: Call `wait()` or `waitpid()` after child process terminates -2. **Use process.poll()**: Check if process is still running before terminating -3. **Graceful shutdown**: Try `terminate()` before `kill()` -4. **Timeout handling**: Use `wait(timeout=N)` to prevent hanging -5. **Error recovery**: Multiple fallback levels in try/except blocks -6. **Track all processes**: Store handles for all spawned processes, not just the primary one -7. **Cleanup in finally**: Ensures cleanup happens even if exceptions occur - -## Related Issues - -This fix prevents: -- Zombie processes accumulating over time -- Process table filling up -- System resource leaks -- Confusing process listings for users - -## Implementation Date - -2026-02-06 - -## Additional Notes - -- The fix follows the same patterns used in other INTERCEPT decoders -- Compatible with existing SDR device selection implementation -- No breaking changes to API or user interface -- Applies to both manual monitoring and

WebSocket requests don't always carry session cookies reliably. Allow /ws/ paths through the login check since the page that initiates these connections already requires authentication. Also keeps the prior fix: serialize WebSocket sends through a queue to avoid concurrent read/write on the non-thread-safe simple-websocket.
