[Bug] Duplicate Thumbnail Uploads
Summary
When uploading thumbnails, the application fails to prevent duplicate uploads, resulting in unnecessary storage space consumption and potential performance issues. This bug affects the backend of the application, specifically the thumbnail upload functionality.
Scope
The bug is confined to the backend of the application, where thumbnail uploads are processed. This means that the issue is not related to the frontend user interface, but rather to the server-side logic responsible for handling thumbnail uploads.
Steps to Reproduce
To reproduce this bug, follow these steps:
- Create a new thumbnail upload request: Use a tool like Postman or cURL to send a request to the backend API to upload a new thumbnail.
- Upload the same thumbnail multiple times: Repeat step 1 multiple times, using the same thumbnail file each time.
- Verify the uploaded thumbnails: Check the backend database or storage system to confirm that multiple copies of the same thumbnail have been uploaded.
Expected Results
When uploading a thumbnail, the application should verify whether a duplicate thumbnail already exists in the system. If a duplicate is found, the application should prevent the upload and return an error message to the user.
Actual Results
However, due to the bug, the application fails to prevent duplicate thumbnail uploads. Instead, multiple copies of the same thumbnail are uploaded, resulting in unnecessary storage space consumption and potential performance issues.
Screenshot
To visualize the bug, consider the following screenshot:
In this screenshot, we can see that multiple copies of the same thumbnail have been uploaded, resulting in a cluttered and inefficient storage system.
Causes of the Bug
The bug is likely caused by a combination of factors, including:
- Lack of duplicate check: The application fails to verify whether a duplicate thumbnail already exists in the system before uploading a new one.
- Insufficient error handling: The application does not properly handle errors related to duplicate thumbnail uploads, resulting in unnecessary storage space consumption and potential performance issues.
Consequences of the Bug
The bug has several consequences, including:
- Unnecessary storage space consumption: Multiple copies of the same thumbnail are uploaded, resulting in unnecessary storage space consumption.
- Potential performance issues: The cluttered and inefficient storage system can lead to performance issues, including slower upload and download times.
- Data integrity issues: The bug can compromise data integrity by allowing multiple copies of the same thumbnail to be uploaded, potentially leading to data corruption or loss.
Solution
To fix the bug, we need to implement a duplicate check mechanism to prevent multiple copies of the same thumbnail from being uploaded. This can be achieved by:
- Verifying thumbnail existence: Before uploading a new thumbnail, verify whether a duplicate thumbnail already exists in the system.
- Returning an error message: If a duplicate thumbnail is found, return an error message to the user, preventing the upload from proceeding.
- Improving error handling: Properly handle errors related to duplicate thumbnail uploads, ensuring that application behaves correctly and efficiently.
Implementation
To implement the solution, we can use the following steps:
- Add a duplicate check mechanism: Implement a duplicate check mechanism to verify whether a duplicate thumbnail already exists in the system.
- Modify the upload logic: Modify the upload logic to prevent multiple copies of the same thumbnail from being uploaded.
- Test the solution: Thoroughly test the solution to ensure that it works correctly and efficiently.
