Error Handling: The method CleanInvalidEdgeKeys uses log.Fatalf which will cause the program to exit if an error occurs during the scanning of keys. Consider handling this error more gracefully to avoid crashing the entire application. |
Error Checking: The error checking in the deletion of keys seems incorrect. The statement if err := localStorage.DeleteRawKey(key); err != true is checking if the error is equal to true , which is not a typical pattern in Go for error handling. It should check for nil to ensure the operation was successful. | |
Resource Cleanup: There is no handling of potential resource leaks or failures in the Redis connections used in CleanInvalidEdgeKeys . Consider adding proper cleanup or retry mechanisms. |

Possible bug |
Improve error handling in key deletion logic___ **Consider handling the error fromlocalStorage.DeleteRawKey(key) properly instead of comparing the error to true . Use a nil check to determine if the deletion was successful.**
[gateway/server.go [1956]](https://github.com/TykTechnologies/tyk/pull/6381/files#diff-4652d1bf175a0be8f5e61ef7177c9666f23e077d8626b73ac9d13358fa8b525bR1956-R1956)
```diff
-if err := localStorage.DeleteRawKey(key); err != true {
+if err := localStorage.DeleteRawKey(key); err != nil {
```
Suggestion importance[1-10]: 9Why: The suggestion correctly identifies a potential bug where the error handling is improperly done by comparing the error to `true` instead of checking if it is `nil`. This change is crucial for proper error handling. | 9 |
Possible issue |
Prevent server crash on recoverable errors___ **Replace thelog.Fatalf with log.Printf followed by a return statement to prevent the server from exiting unexpectedly due to a recoverable error.** [gateway/server.go [1950]](https://github.com/TykTechnologies/tyk/pull/6381/files#diff-4652d1bf175a0be8f5e61ef7177c9666f23e077d8626b73ac9d13358fa8b525bR1950-R1950) ```diff -log.Fatalf("Error scanning keys: %v", err) +log.Printf("Error scanning keys: %v", err) +return ``` Suggestion importance[1-10]: 8Why: Changing `log.Fatalf` to `log.Printf` followed by a return statement prevents the server from crashing on recoverable errors, which improves the robustness of the application. | 8 |
Maintainability |
Replace magic strings with constants for better code maintainability___ **Use a constant for the key prefix "apikey-" and "quota" to avoid magic strings andfacilitate maintenance.** [gateway/server.go [1948-1960]](https://github.com/TykTechnologies/tyk/pull/6381/files#diff-4652d1bf175a0be8f5e61ef7177c9666f23e077d8626b73ac9d13358fa8b525bR1948-R1960) ```diff -keys, err := localStorage.ScanKeys("apikey-*") -quotaKey := strings.Replace(key, "apikey", "quota", 1) +const apikeyPrefix = "apikey-" +const quotaPrefix = "quota" +keys, err := localStorage.ScanKeys(apikeyPrefix + "*") +quotaKey := strings.Replace(key, apikeyPrefix, quotaPrefix, 1) ``` Suggestion importance[1-10]: 7Why: Using constants for the key prefixes improves code readability and maintainability by avoiding magic strings. This is a good practice but not critical. | 7 |
Enhancement |
Add nil check for keys slice to handle cases where no keys are found___ **Add error handling for thelocalStorage.ScanKeys method to handle possible nil keys slice when an error occurs.** [gateway/server.go [1948-1950]](https://github.com/TykTechnologies/tyk/pull/6381/files#diff-4652d1bf175a0be8f5e61ef7177c9666f23e077d8626b73ac9d13358fa8b525bR1948-R1950) ```diff keys, err := localStorage.ScanKeys("apikey-*") if err != nil { - log.Fatalf("Error scanning keys: %v", err) + log.Printf("Error scanning keys: %v", err) + return +} +if keys == nil { + log.Printf("No keys found to process.") + return } ``` Suggestion importance[1-10]: 7Why: Adding a nil check for the keys slice ensures that the code handles cases where no keys are found, which enhances the robustness of the function. This is a useful enhancement but not critical. | 7 |
