Title: fileservice: add i/o timeout as retryable error

Problem 1: Lack of Detailed Explanation

The title and body of the pull request lack detailed explanation. It would be beneficial to provide more context on why adding i/o timeout as a retryable error is necessary. This information can help reviewers understand the rationale behind the change and its impact on the codebase.

Problem 2: Security Concern - Retrying on I/O Timeout

Retrying on I/O timeout can potentially lead to unintended consequences, such as increased load on the system or causing delays in error handling. It is crucial to carefully consider the implications of retrying on I/O timeout and ensure that it aligns with the application's error handling strategy.

Suggestion 1: Detailed Explanation

Provide a more detailed explanation in the pull request description about why retrying on I/O timeout is necessary and how it benefits the application. This will help in understanding the motivation behind the change.

Suggestion 2: Security Review

Conduct a thorough security review to assess the impact of retrying on I/O timeout. Consider scenarios where retrying on I/O timeout may introduce vulnerabilities or impact the application's stability.

Optimization:

Consider adding unit tests to cover the scenario of retrying on I/O timeout to ensure that the behavior is correctly implemented and does not introduce regressions.

Overall:

While the addition of i/o timeout as a retryable error can be useful in certain scenarios, it is essential to carefully evaluate the implications and ensure that it aligns with the application's error handling strategy. Providing more context and conducting a security review can help in addressing potential issues and optimizing the changes made in the pull request.
