The code provided contains a few issues and potential improvements:
-
Redundancy in
DeleteMethod Call: The first branch of the conditional statement deletes the user with old permissions, while the second branch does not. This can lead to unintended behavior if there are no existing users with that permission. -
Handling Root User Deletion: The root user is handled differently based on whether the condition is met within the loop or after it. However, this logic seems unnecessary given how the root user deletion should only occur when all checks pass.
-
Optimization Suggestion:
- Remove the redundant
info.Name = "*". It doesn't affect function behavior but could be removed for clarity.
- Remove the redundant
Here's the cleaned-up version:
func (r *Local) ChangeAccess(info AccessChangeInfo) error {
info.Password = r.Password
switch {
case info.Permission != "":
if err := r.Delete(DeleteInfo{
Version: info.Version,
Username: info.Username,
Permission: info.OldPermission,
ForceDelete: true,
Timeout: 300}); err != nil {
return err
}
if info.Username == "root" {
return nil
}
default:
if err := r.createUser(CreateInfo{
Name: info.Name,
// Rest of the createUser parameters
}); err != nil {
return err
}
return r.changeUserAccess(UserModifyOptions{ // Assuming changeUserAccess exists
OldPermissions: []string{info.OldPermission},
NewPermissions: []string{info.Permission},
Usernames: []string{info.Username},
Version: info.Version,
})
}
}Key Improvements Made:
- Simplified the conditional structure using a switch, making the code more concise.
- Removed the
info.Name = "*"assignment since it wasn't doing anything meaningful. - Added a default case to handle cases where
info.Permissionisn’t an empty string, ensuring proper handling of both new and permission changes.

There is no significant irregularity, issue, or optimization suggestion in the provided code snippet. The changes you made to modify permission handling do not seem to introduce any new problems or improve efficiency beyond what was already present in the original version.

The changes made do not have significant irregularities or issues.
However, there is room for improvement:
-
Comments: The comment about skipping accounts that cannot be found in the map can be moved outside of the loop if you want to reduce redundant checks within each iteration cycle.
for _, account := range accounts { if _, ok := accountMap[account]; !ok { continue } // Rest of the deletion logic }
-
Code Readability:
- The line
if _, ok := accountMap[account]; !ok {could usecontinue;on its own per iteration instead of repeating the expression multiple times. - Consider extracting the client creation logic into a helper function to maintain cleaner code structure.
- The line
Overall, the patch looks well-maintained and optimized given the current constraints.
