佛山网站优化效果北京网站制作公司有哪些
有时某个项目遇到疑难问题，发现早期版本正常，现在的版本异常，而从代码或日志分析异常困难，这时通过二分法夹版本会更加快捷有效，而两个版本的差异提交如何看呢？

- git diff r2s/sm8250/master…r2s/sm8250/release 查看release中比master中多提交了哪些内容，反着写显示效果完全不一样。

- git diff r2s/sm8250/master…r2s/sm8250/release 查看release和master所有差异点
- git log r2s/sm8250/master…r2s/sm8250/release 查看以git log的方式展示差异
- git log -lefg-right r2s/sm8250/release…r2s/sm8250/master 显示提交在哪个分支上。
- git rev-list r2s/sm8250/master…r2s/sm8250/release 查看release中比master中多的提交，只显示commitid，不显示内容。
- 除了gerrit有Change-Id，切了分支也不会变化，但Commit id，切了分支后就变化了，所以对比commitid也无法对比差异。可以git log -1000 > master.txt ，再 git log -1000 > release.txt，然后对比工具对比master.txt和 release.txt发现最下面的都一样，最上面存在合入顺序上的差异，以及差异提交。可以把message里的一行描述grep出来进行对比。也可以把这一行message复制到excel里，出现两次就是都存在的提交，出现1次就是独有的提交。
1:共有的
2：master独有的
3：release独有的
