0.8.0

What's Changed

• Improved Meshtastic connection handling by @jeremiah-k in #76

New Features & Bugfixes

Graceful Shutdown Handling

Signal Handling for SIGINT and SIGTERM:

• The application now properly handles shutdown signals (Ctrl+C or termination signals) to ensure a clean and graceful shutdown process.
• Signal handlers are set up to capture SIGINT and SIGTERM, triggering the shutdown procedure without abrupt termination.

Shutdown Event and Task Cancellation:

• Introduced an asyncio.Event (shutdown_event) to manage the shutdown process asynchronously.
• All running tasks are properly canceled during shutdown to prevent resource leaks or incomplete operations.
• Ensures that connections to Matrix and Meshtastic are closed gracefully.

Robust Meshtastic Reconnection Logic

Automatic Reconnection on Device Reboot or Disconnection:

• The application now detects when the Meshtastic device is disconnected (e.g., due to a remote reboot command) and attempts to reconnect automatically.
• Implemented exponential backoff for reconnection attempts, starting from 10 seconds and capping at 5 minutes.

Thread-Safe Reconnection Handling:

• Utilized threading locks (meshtastic_lock) to prevent race conditions and ensure thread safety during reconnection attempts.
• Introduced flags (reconnecting and shutting_down) to manage the reconnection state and prevent overlapping reconnection attempts.

Enhanced Error Handling and Logging

Specific Exception Handling:

• Added exception handling for OSError with errno 9 (Bad file descriptor) to avoid unnecessary warnings when closing already closed connections.
• Handled exceptions during client closure and reconnection to prevent crashes and provide informative logs.

Informative Logging Statements:

• Improved logging throughout the application to provide clear insights into the application's state and actions.
• Logs include connection attempts, reconnection successes or failures, and shutdown processes.

Please test and report any issues.
