β‘ Recommended focus areas for review Synchronization Issue The struct `TestChange` includes a `sync.Mutex`. However, the `Copy` method returns a copy of `TestChange` by value, which can lead to copying of the mutex. This is generally unsafe and can cause runtime issues as mutexes should not be copied. |

Prevent potential concurrency issues by avoiding copying mutexes by value___ **Avoid copying the mutex by value in theCopy method of TestChange struct. This can lead to subtle bugs by copying the lock state. Consider returning a pointer to a new instance of TestChange or explicitly handling the mutex.**
[apidef/bad.go [7-8]](https://github.com/TykTechnologies/tyk/pull/6634/files#diff-62e2fc9df5eff27d39d10a8f2ef85be72987435733e4b1d040be9905fe805fa5R7-R8)
```diff
-func (p TestChange) Copy() TestChange {
- return p
+func (p *TestChange) Copy() *TestChange {
+ return &TestChange{}
}
```
Suggestion importance[1-10]: 9Why: The suggestion addresses a critical concurrency issue by preventing the mutex from being copied by value, which can lead to subtle bugs. Changing the method to return a pointer to a new instance of `TestChange` is a valid and necessary improvement to ensure thread safety. | 9 |
