In your second code snippet, the issue is that the code responsible for loading, filtering, and displaying the data in your table widget is missing. In your first code snippet, after performing the cleanup of old data, you proceed to:
1. Retrieve user inputs for filtering (start date, end date, status, hostname, duration).
2. Read the cleaned data from the file.
3. Apply the filters to the data.
4. Populate the table widget with the filtered data.
5. Update the status bar with counts.
However, in your second code snippet, after performing the cleanup, you do not include these steps. As a result, the function ends without displaying any data.
**Here's what's happening in your second code:**
1. **File Cleanup:**
- You acquire a file lock.
- Read all lines from `history_online.txt`.
- Remove lines older than 180 days and write the remaining lines to a temporary file.
- Replace the original file with the cleaned temporary file.
2. **Function Ends:**
- After the `try` block, the function ends without proceeding to load and display the data.
**To fix the issue, you need to add the data loading and displaying code after the cleanup.** Here's how you can modify your second code snippet:
```python
def load_data(self):
file_path = 'history_online.txt'
lock_path = 'history_online.lock'
temp_file_path = 'history_online_temp.txt'
lock = FileLock(lock_path)

date_format = "%Y-%m-%d"

return date < datetime.now() - timedelta(days=180)
except ValueError:
return True

if not os.path.exists(file_path):
return

lines_before_cleanup = len(lines)
lines_after_cleanup = 0

```
**Explanation:**
- **Adding Data Loading and Display Code:**
- After performing the file cleanup and releasing the file lock, you need to read the updated `history_online.txt` file.
- Retrieve the user inputs for filtering (start date, end date, status filter, hostname filter, duration filter).
- Iterate over the lines in the file, parse each line, and apply the filters.
- Collect the filtered data into the `rows` list.
- Reverse the `rows` list to show the latest entries first.
- Populate your table widget with the data from `rows`.
- Update the status bar with the counts of total entries, WAN down entries, and server down entries.
- **Why This Fix Works:**
- In your first code snippet, the data loading, filtering, and displaying code is present, so the data appears in your table widget.
- In the second code snippet, this part was missing, so no data was displayed.
- By adding this code back into your function, you ensure that after cleaning up the file, you proceed to display the data to the user.
**Additional Suggestions:**
- **Code Organization:**
- Consider separating the file cleanup logic from the data loading and displaying logic. This can make your code more modular and easier to read.
- You can create separate functions, e.g., `def cleanup_old_data(self):` and `def display_data(self):`, and call them within `load_data`.
- **Error Handling:**
- Ensure that the error handling in your code is appropriate. Currently, any exception in the `try` block will print an error message and end the function.
- If an exception occurs during file cleanup, you might still want to attempt to load and display whatever data is available.
- **File Locking:**
- Make sure that the file lock is appropriately applied during both the cleanup and data loading phases if necessary.
**Recap:**
The primary reason your new code isn't displaying data is that you omitted the part of the code that reads the data from the file, filters it based on user input, populates the table widget, and updates the status bar. By adding this code back into your function, your application should display the data as expected.
