PR Analysis

• 🎯 Main theme: Refactoring error handling in the backend package

• 📝 PR summary: This PR is focused on refactoring the error handling mechanism in the backend package. The error channel (errChan) that was previously used to handle errors in various functions has been removed. Instead, functions now directly handle errors without passing them through this channel. This change simplifies the error handling process and makes the code cleaner and easier to understand.

• 📌 Type of PR: Refactoring

• 🧪 Relevant tests added: No

• 🔒 Security concerns: No security concerns found

  PR Feedback

• 💡 General suggestions: The PR is well-structured and the changes are clear. The removal of the error channel and handling errors directly within functions simplifies the error handling process and makes the code cleaner. However, it would be beneficial to ensure that all error handling is consistent across the codebase. Also, it's important to ensure that this change doesn't affect the error handling functionality and all errors are properly caught and handled.

• 🤖 Code feedback:

  • relevant file: mainhandler/kubescapehandler.go suggestion: Consider adding more context to the error messages to make them more informative. This can be done by including more details about the operation that failed. [medium] relevant line: data.reporter.SendError(err, sendReport, true)

  • relevant file: mainhandler/vulnscan.go suggestion: It's a good practice to avoid hardcoding strings. Consider moving the string "secret loaded" to a constant. [medium] relevant line: sessionObj.Reporter.SendDetails("secret loaded", registryScan.sendReport)

  • relevant file: mainhandler/handlerequests.go suggestion: It's recommended to use structured logging. It provides a consistent logging schema, better search experience and analytical capabilities. [medium] relevant line: logger.L().Info(info)

  • relevant file: watcher/watcher.go suggestion: Changing an error log to a debug log may cause missing important information when debugging. Make sure this information is not critical for error investigation. [important] relevant line: logger.L().Debug(fmt.Sprintf("error to getParentIDForPod, err :%s", err.Error()), helpers.Error(err))
