Unused `_isActivePlayer()` Function

Root + Impact

Description

  • * The contract defines an internal function `_isActivePlayer()` that checks if `msg.sender` is an active player in the raffle by iterating through the `players` array.

    * This function is never called anywhere in the contract code, making it dead code that wastes deployment gas and confuses readers about the contract's intended functionality.

    ```solidity:172:180:src/PuppyRaffle.sol

    /// @notice this function will return true if the msg.sender is an active player

    function _isActivePlayer() internal view returns (bool) {

    for (uint256 i = 0; i < players.length; i++) {

    if (players[i] == msg.sender) {

    return true;

    }

    }

    return false;

    }

    ```


Risk

Likelihood:

  • * This function exists in the codebase but is never invoked

    * The function is defined and compiled into the bytecode, consuming gas during deployment

    * Code reviewers may assume it's used somewhere, leading to confusion

Impact:

  • * Unnecessary gas consumption during contract deployment

    * Code confusion - suggests incomplete implementation

    * Maintenance burden - unclear if function should be used or removed

    * Potential for future developers to misunderstand contract design

Proof of Concept

```solidity
// Search entire codebase for _isActivePlayer()
// Result: Only found in definition, never called
// Function is dead code
```

Recommended Mitigation

```diff
- /// @notice this function will return true if the msg.sender is an active player
- function _isActivePlayer() internal view returns (bool) {
- for (uint256 i = 0; i < players.length; i++) {
- if (players[i] == msg.sender) {
- return true;
- }
- }
- return false;
- }
```
If the function was intended for future use, document it clearly or implement the intended functionality. Otherwise, remove it to reduce gas costs and eliminate confusion.
