3-6: Consider enhancing the fix description for better traceability.While the fix description is clear, it could be more detailed to help users and developers understand the scope and impact of the change.
Consider expanding the description like this:
## [1.3.0] - 2024-12-11 ### Fixed -Fixed issue with Task not throwing even when retry failed. +Fixed issue where Task would silently continue execution instead of throwing an exception when file transfer retry attempts failed (#49).🧰 Tools

191-196: LGTM! The error handling improvement properly addresses the retry failure issue.The changes correctly implement specific exception handling for FTP command failures, ensuring that retry failures are properly propagated while maintaining detailed error logging.
Consider enhancing the error message to include the verification failure context:
- _logger.NotifyError(_batchContext, $"Failed to delete corrupted file '{_destinationFileDuringTransfer}': {ex.Message}", ex); + _logger.NotifyError(_batchContext, $"Failed to delete corrupted file '{_destinationFileDuringTransfer}' after verification failure: {ex.Message}", ex);
Line range hint
177-190: Consider enhancing the verification process with size pre-check.While the current implementation correctly verifies the transfer and handles failures, you could optimize the process by checking file sizes before performing a full content comparison.
Consider adding a size check before the full comparison:
+ var sourceSize = new FileInfo(_sourceFileDuringTransfer).Length; + var destSize = _client.GetFileSize(_destinationFileDuringTransfer); + if (sourceSize != destSize) + { + _client.DeleteFile(_destinationFileDuringTransfer); + throw new ArgumentException($"Transferred file size mismatch. Source: {sourceSize}, Destination: {destSize}. File {Path.GetFileName(_sourceFileDuringTransfer)} was corrupted during transfer."); + } if ((verifyOptions == VerifyOptions.Retry || verifyOptions == VerifyOptions.Throw) && _client.CompareFile(_sourceFileDuringTransfer, _destinationFileDuringTransfer, FtpCompareOption.Auto) == FtpCompareResult.NotEqual)
Line range hint
169-174: Enhance verification options validation.While the code safely handles invalid verification options by defaulting to None, this silent fallback could mask configuration issues.
Consider throwing an exception for invalid options:
if (!Enum.TryParse<FtpVerify>(verifyOptions.ToString(), out var verifyOption)) { - // Handle the parsing failure, perhaps set a default value or log an error - verifyOption = FtpVerify.None; // or choose an appropriate default + throw new ArgumentException($"Invalid verification option: {verifyOptions}. Valid options are: {string.Join(", ", Enum.GetNames(typeof(FtpVerify)))}"); }

394-398: LGTM! Clean switch expression refactoring
The switch expression is a good modernization that makes the code more concise while maintaining readability.
190-195: Verify retry failure test coverage
Since this PR fixes an issue with retry failures not throwing errors, we should ensure proper test coverage for this scenario.
✅ Verification successful
Let me gather more specific information about the test coverage.
Let me search for test methods that specifically test error scenarios and retries.
Based on the previous results, I can see that while there are tests for VerifyOptions.Retry and VerifyOptions.Throw, we need to verify if they specifically cover the error scenario being fixed. Let me check the test implementations more thoroughly.
Based on the test file content, I can now provide a final response:
Test coverage for retry failures is adequate
The test file includes comprehensive coverage for retry failures through two specific test methods:
UploadFTP_TestVerifyOptionsRetry: Tests the retry mechanism with corrupted files over multiple attemptsUploadFTP_TestVerifyOptionsThrow: Verifies that exceptions are properly thrown when verification fails
The tests specifically validate:
- Retry behavior with multiple attempts (RetryAttempts = 5)
- Exception propagation when verification fails
- Error message content for verification failures
