这 2 个提交已从历史记录中消失：。
2f79bbc JIRA-76 MP Payment Acceptance with fixed Acceptance type
842c02f JIRA-59 Multiple Payee dashboard changes
以为我相当了解 git，但这让我非常困惑。
如果提交有多个祖先，你将在日志中看到所有祖先交错，按时间戳排序。 所以我猜你有这样的情况：
A --> B --> C ---> D
-----> E ----> F
你最初在A，所以你的日志显示你A、B、C、E、D、F。 然后你签出(说(C，所以现在你只能看到C和D。
确认这一点的最简单方法是使用 --graph 标志重新运行git log。
