编号承诺挡旧提议

- 位置：《分布式系统与一致性》第10章《共识算法Paxos》Paxos两阶段英文条文及注解（源文件：_epub-src/OEBPS/Text/chapter14.xhtml） - 结论依据：原文条文"If an acceptor receives a prepare request with number n greater than that of any prepare request to which it has already responded,then it responds...with a promise not to accept any more proposals numbered less than n"，以及"If an acceptor receives an accept request for a proposal numbered n,it accepts the proposal unless it has already responded to a prepare request having a number greater than n"；注解明确"这个新的提议编号是n，值是已接受的编号最大的提议中的值，如果没有接受的提议，则可以是proposer要提议的任何值"。 - 原始内容：then it responds to the request with a promise not to accept any more proposals numbered less than n and with the highest-numbered proposal (if any) that it has accepted...proposer并没有把所收到的编号最大的提议放在accept消息里，而是构建了一个新的提议，这个新的提议编号是n，值是已接受的编号最大的提议中的值，如果没有接受的提议，则可以是proposer要提议的任何值。
