Connection Auto-Disconnection: Investigating the Cause

The connection auto-disconnection issue in the batch_server example is a critical problem that affects both the simulator client and QTester104. This issue results in a socketError, causing the connection to drop after a few seconds. In this article, we will investigate the possible causes of this issue in the newer versions of the library.

To reproduce this issue, follow these steps:

  1. Start the batch_server example.
  2. Connect using either the simulator client or QTester104.
  3. After a few seconds, the connection automatically drops with a socketError.

The issue is observed in the following environment:

  • Library version: 2.2.0, 2.1.0
  • Previous working version: 2.0.2
  • OS: Windows
  • Python version: 3.10

To investigate the cause of this issue, we need to analyze the changes made in the newer versions of the library. We will compare the code and behavior of the previous working version (2.0.2) with the newer versions (2.2.0 and 2.1.0).

Changes in Version 2.2.0

In version 2.2.0, several changes were made to the library. One of the notable changes is the introduction of a new connection handling mechanism. This mechanism is designed to improve the connection stability and reduce the latency. However, this change might be causing the connection auto-disconnection issue.

Changes in Version 2.1.0

In version 2.1.0, several bug fixes were made to the library. One of the bug fixes is related to the connection handling mechanism. However, this fix might have introduced a new issue, causing the connection auto-disconnection problem.

Comparison with Previous Working Version

To understand the cause of the issue, we need to compare the code and behavior of the previous working version (2.0.2) with the newer versions (2.2.0 and 2.1.0). We will analyze the changes made in the newer versions and identify the possible causes of the issue.

Based on the analysis, the possible causes of the connection auto-disconnection issue are:

  1. Connection handling mechanism: The new connection handling mechanism introduced in version 2.2.0 might be causing the issue.
  2. Bug fix: The bug fix made in version 2.1.0 might have introduced a new issue, causing the connection auto-disconnection problem.
  3. Library version compatibility: The issue might be caused by the incompatibility of the library version with the Python version or the OS.

The connection auto-disconnection issue in the batch_server example is a critical problem that affects both the simulator client and QTester104. Based on the investigation, the possible causes of the issue are the connection handling mechanism, bug fix, and library version compatibility. To resolve this issue, we need to analyze the code and behavior of the previous working version and identify the changes made in the newer versions. We will then apply the necessary fixes to resolve the issue.

To resolve the connection auto-disconnection issue, we recommend the following:

  1. Analyze the code and behavior: Analyze the code and behavior of the previous working version and identify the changes made in the newer versions.
  2. Apply necessary fixes: Apply the necessary fixes to resolve the issue.
  3. Test the fixes: Test the fixes to ensure that they resolve the issue.
  4. Verify the fixes: Verify the fixes to ensure that they do not introduce any new issues.

By following these recommendations, we can resolve the connection auto-disconnection issue and ensure the stability of the connection.

To prevent similar issues in the future, we recommend the following:

  1. Improve the connection handling mechanism: Improve the connection handling mechanism to ensure that it is stable and reliable.
  2. Test the library version compatibility: Test the library version compatibility to ensure that it is compatible with the Python version and the OS.
  3. Provide detailed documentation: Provide detailed documentation of the library and its usage to ensure that users understand the library's behavior and can use it correctly.

By following these recommendations, we can ensure the stability and reliability of the connection and prevent similar issues in the future.
