#### Update Flow
412
+
413
+
When an update is triggered (either automatically or via `/update` command), the bot follows this process:
414
+
415
+
1. **Stash Local Changes**: Any uncommitted local modifications are automatically stashed to prevent conflicts
416
+
2. **Fetch Remote Changes**: Retrieves the latest commits from the remote repository
417
+
3. **Check for Updates**: Verifies if there are new commits to pull
418
+
4. **Pull Changes**: Applies the updates using `git pull`
419
+
5. **Save Queue**: Forces a save of the current queue to disk to prevent data loss
420
+
6. **Display Commit Info**: Shows the latest commit message with author and timestamp
421
+
7. **Restart Bot**: Gracefully restarts the bot via PM2 with updated environment variables
422
+
423
+
#### Error Handling
424
+
425
+
Each step in the update process includes comprehensive error handling:
426
+
427
+
- **Stash Failures**: Reports if local changes cannot be stashed
428
+
- **Fetch Failures**: Reports connection or repository access issues
429
+
- **Pull Failures**: Reports merge conflicts or pull errors
430
+
- **Restart Failures**: Provides instructions to manually restart if PM2 fails
431
+
- **Descriptive Messages**: Each error includes specific information about what went wrong
432
+
433
+
The updater handles the normal PM2 `SIGINT` signal correctly and won't report it as an error during successful restarts.
