没有做任何更改时Git合并冲突

我克隆了一个回购,然后,几个小时后,我做了'git pull'.但是出现了合并冲突,我不明白为什么,因为我没有对克隆回购进行任何改动.

首先,我每天都在使用一些预防措施......

git merge --ff-only当我不期望任何实际的合并时,我学会了使用.我看到它也可以使用,git pull --ff-only但我经常使用git pull --rebase它,因此它不会创建任何合并提交,而是在上游重放我的本地更改(如果有的话).但是,我无法解释这个问题,因为我不知道linux-next的规则.

合并冲突的唯一原因是合并到不同的分支.如果你的分支没有改变,人们会期待一个干净的快进合并.适合您的描述的唯一解释是远程不再在其历史记录中包含您的提交,这意味着上游具有重写的历史记录.这在一些工作流程中非常常见,其中已发布的分支只是指向最新提交更多更改集的指针.但是我没有关于linux-next的具体信息.

危险区域:出现这种情况时,您可以使用git fetch(然后使用实际远程和分支名称git reset --hard origin/master替换origin和master)来获取上游数据,然后更新您的分支参考.但是请确保您没有任何想要保存的更改,因为这是一种破坏性操作.
