I was working with a friend on a project, and he edited a bunch of files that shouldn't have been edited. Somehow I merged his work into mine, either when I pulled it, or when I tried to just pick the specific files out that I wanted. I've been looking and playing for a long time, trying to figure out how to remove the commits that contain the edits to those files, it seems to be a toss up between revert and rebase, and there are no straightforward examples, and the docs assume I know more than I do.
下面是这个问题的简化版本:
给定下面的场景，我如何删除提交2?
$ mkdir git_revert_test && cd git_revert_test
$ git init
Initialized empty Git repository in /Users/josh/deleteme/git_revert_test/.git/
$ echo "line 1" > myfile
$ git add -A
$ git commit -m "commit 1"
[master (root-commit) 8230fa3] commit 1
1 files changed, 1 insertions(+), 0 deletions(-)
create mode 100644 myfile
$ echo "line 2" >> myfile
$ git commit -am "commit 2"
[master 342f9bb] commit 2
1 files changed, 1 insertions(+), 0 deletions(-)
$ echo "line 3" >> myfile
$ git commit -am "commit 3"
[master 1bcb872] commit 3
1 files changed, 1 insertions(+), 0 deletions(-)
预期的结果是
$ cat myfile
line 1
line 3
以下是我一直试图恢复的一个例子
$ git revert 342f9bb
Automatic revert failed. After resolving the conflicts,
mark the corrected paths with 'git add <paths>' or 'git rm <paths>'
and commit the result.
所以你做了一些工作并推动了它，我们称之为提交A和b。你的同事也做了一些工作，提交C和d。你将你同事的工作合并到你的工作中(合并提交E)，然后继续工作，也提交了(提交F)，然后发现你的同事修改了一些他不应该修改的东西。
你的提交历史是这样的:
A -- B -- C -- D -- D' -- E -- F
你真的想摆脱C D D'既然你说你将同事的工作合并到你的工作中，这些提交已经“存在”了，所以使用git rebase等方法删除这些提交是不可以的。相信我，我试过了。
现在，我看到了两条出路:
if you haven't pushed E and F to your coworker or anyone else (typically your "origin" server) yet, you could still remove those from the history for the time being. This is your work that you want to save. This can be done with a
git reset D'
(replace D' with the actual commit hash that you can obtain from a git log
At this point, commits E and F are gone and the changes are uncommitted changes in your local workspace again. At this point I would move them to a branch or turn them into a patch and save it for later. Now, revert your coworker's work, either automatically with a git revert or manually. When you've done that, replay your work on top of that. You may have merge conflicts, but at least they'll be in the code you wrote, instead of your coworker's code.
If you've already pushed the work you did after your coworker's commits, you can still try and get a "reverse patch" either manually or using git revert, but since your work is "in the way", so to speak you'll probably get more merge conflicts and more confusing ones. Looks like that's what you ended up in...
我有一个简单的解决方案，使用补丁恢复您所有的更改。
检查当前的主要分支机构(例如开发)
git checkout develop
在历史日志中查找你的commit-id，只签出你对一个新分支的更改:
git log
git checkout -b your-branch <your-commit-id>
在你的分支中查找，找到你想要恢复到的前一个状态:
git checkout -b prev-status <previous-commit-id>
创建一个补丁，可以恢复您的所有更改:
git diff your-branch..prev-status > reverts.patch
# the comparing order of branches is important
检查当前的头分支，并应用恢复补丁
git checkout origin develop
git apply reverts.patch
git add *
git commit -m "revert all my changes"
