我怎样才能回去测试什么东西坏了？ [英] How can I go back and test where something broke?

问题描述

我想回到之前的提交并运行我的程序，直到我发现某些内容在没有删除或影响我的提交的情况下崩溃。一旦找到最后一次提交的地方，我可以看到什么改变了回到当前的提交并修复它。

我该怎么做？ 正确的命令： git bisect 。它将执行二进制搜索，并允许您将每个测试提交标记为 good 或 bad

开始平分过程：

  git bisect start HEAD< last good commit> 
  

然后构建源代码，运行它，检查错误并最终标记它：

  git bisect good＃或：
 git bisect bad 
  

如果您无法测试提交（构建损坏等），请使用 git bisect skip 跳过它。

直到找到第一个坏提交为止。要回到原始提交，请运行 git bisect reset 。

I want to go back to prior commits and run my program until I found out where something broke without deleting or affecting my commits. Once I find the last commit where it was working I can see what changed the go back to the current commit and fix it.

How would I do this?

解决方案

Git provides just the right command for that: git bisect. It will perform a binary search and allows you to mark each tested commit either good or bad

Start the bisect procedure with:

git bisect start HEAD <last good commit>

Then build your source, run it, check for errors, and finally mark it:

git bisect good # or:
git bisect bad

If you cannot test a commit (build broken, etc.), skip it with git bisect skip.

Do that until you found the first bad commit. To get back to your original commit, run git bisect reset.
