透明代理-解决的问题没有讲清楚

[0xcmhy]

Proxy Contract和Implementation Contract有一个名称和参数相同的函数。想象一下，如果Proxy Contract有一个owner()函数，Implementation Contract也有。在透明代理合约中，这个问题由Proxy Contract来处理，Proxy Contract根据msg.sender全局变量来决定用户的调用是在Proxy Contract本身还是在Implementation Contract中执行。

文中的代码没有演示清楚。假设应该是admin调用了proxy的和logic 相同的selector时，proxy能区分开来，并且争取调用。而不是单单报错。
代码应该给下面的demo
`
/**
* @dev If caller is the admin process the call internally, otherwise transparently fallback to the proxy behavior.
*/
function _fallback() internal virtual override {
if (msg.sender == _proxyAdmin()) {
if (msg.sig != ITransparentUpgradeableProxy.upgradeToAndCall.selector) {
revert ProxyDeniedAdminAccess();
} else {
_dispatchUpgradeToAndCall();
}
} else {
super._fallback();
}
}

/**
 * @dev Upgrade the implementation of the proxy. See {ERC1967Utils-upgradeToAndCall}.
 *
 * Requirements:
 *
 * - If `data` is empty, `msg.value` must be zero.
 */
function _dispatchUpgradeToAndCall() private {
    (address newImplementation, bytes memory data) = abi.decode(msg.data[4:], (address, bytes));
    ERC1967Utils.upgradeToAndCall(newImplementation, data);
}
