Kingdom: API Abuse

An API is a contract between a caller and a callee. The most common forms of API abuse are caused by the caller failing to honor its end of this contract. For example, if a program fails to call chdir() after calling chroot(), it violates the contract that specifies how to change the active root directory in a secure fashion. Another good example of library abuse is expecting the callee to return trustworthy DNS information to the caller. In this case, the caller abuses the callee API by making certain assumptions about its behavior (that the return value can be used for authentication purposes). One can also violate the caller-callee contract from the other side. For example, if a coder subclasses SecureRandom and returns a non-random value, the contract is violated.

Castor Bad Practices: Unspecified Query Mode

Abstract
The Castor query does not explicitly define a query mode.
Explanation
By default Castor executes queries in shared mode. Since shared mode allows both read and write access, it is unclear what kind of operation the query is intended for. If the object is going to be used in a read-only context, shared access adds unnecessary performance overhead.

Example 1: The following example does not specify a query mode.

results = query.execute();    //missing query mode
