Update service_aix.go

[amrindersingh1820]

1. Lack of Proper Error Handling

   • Original Issue: Many functions did not properly handle or return errors. For example, getArgsFromPid, isInteractive, and Uninstall didn’t adequately report issues.
   • Fix: Ensured all functions return errors when necessary and added descriptive error messages.

2. Missing or Inconsistent Formatting

   • Original Issue: Code formatting was inconsistent, particularly around template definitions, string concatenation, and variable declarations.
   • Fix: Improved formatting for readability and consistency.

3. Unsafe Regex Handling

   • Original Issue: Service name strings were directly embedded in regular expressions, which could cause issues with special characters.
   • Fix: Used regexp.QuoteMeta to escape service names safely.

4. Incorrect Status Parsing

   • Original Issue: Parsing the lssrc output for service status relied on weak assumptions and could result in incorrect matches.
   • Fix: Improved the regex and explicitly handled unknown statuses with an appropriate error.

5. Overlooked File and Path Errors

   • Original Issue: File path checks and operations like os.Stat or os.Remove didn’t always handle errors or check preconditions properly.
   • Fix: Added error checks to ensure paths and files are correctly verified before performing actions like creation or deletion.

6. Race Condition in Restart Logic

   • Original Issue: The Restart method had no delay between Stop and Start, potentially causing race conditions.
   • Fix: Introduced a short sleep (50ms) to ensure the stop operation completes before starting.

7. Poor Handling of Interactive Mode

   • Original Issue: Interactive mode detection lacked robustness and could panic on errors.
   • Fix: Improved the logic in isInteractive and wrapped it in a more descriptive error message.

8. Missing Default Logger for Interactive Mode

   • Original Issue: The Logger method didn’t properly handle interactive environments in a structured way.
   • Fix: Added a fallback to ConsoleLogger for interactive environments.

9. Hardcoded Paths and Symlink Errors

   • Original Issue: The script creation logic for /etc/rc and symlinks lacked checks for existing files and didn’t handle errors in creating symlinks robustly.
   • Fix: Enhanced error handling for path operations and skipped symlinks on failure without interrupting the process.

10. Template Logic Issues

    • Original Issue: The template method didn’t handle cases where optionSysvScript was unset properly.
    • Fix: Added a fallback to default configuration when no custom template was provided.

11. Miscellaneous Issues

    • Incorrect Case Logic: Fixed missing * cases in shell script templates to ensure the default behavior is handled.
    • Magic Numbers: Replaced arbitrary values with meaningful comments and constants where appropriate.
