Thread-safety notes In general, methods on RequestHandler and elsewhere in Tornado are not thread-safe. In particular except from a signal handler. Note that this is the only method in IOLoop that makes this thread-safety guarantee; all other interaction with the IOLoop must be done from that IOLoop’s thread. add_callback()

Kotlin support Requirements Null-safety Kotlin API runApplication Extensions Dependency management @ConfigurationProperties Testing Resources provided by default if one bootstraps a Kotlin project on start.spring.io. Null-safety One of Kotlin’s key features is null-safety. It deals with null values at compile time rather than deferring the problem comprehensive guide to null- safety in Kotlin. Although Java does not allow one to express null-safety in its type system, Spring Framework, Spring Data, and Reactor now provide null-safety of their API via tooling-friendly

Safety Rule Safety Rule 是一个验证节点是否要接受一个新的Proposal的安全性规则，主要 有三条： 1. 判断当前Proposal的View值是否大于本地locked Proposal的View值； 验证当前Proposal的ProposalMsg是否有效； 当一个验证节点收到一个新的提案时，如果满足上述 Safety Rule 的认证，则 会给这个提案进行投票，否则拒绝这次提案。 11.5. PacemakerInterface Hotstuff算法的一大特点就是将共识的liveness和safety分开。PacemakerInterface 是Hotstuff算法Pacemaker的接口定义，外层共识通过实现这些接口，可以推进
