常见问题


删除临时分支

一不小心把本地的临时分支push到server上去了,想要删除。
一开始用

git branch -r -d origin/branch-name

不成功,发现只是删除的本地对该远程分支的track,正确的方法应该是这样:

git push origin :branch-name

冒号前面的空格不能少,原理是把一个空分支push到server上,相当于删除该分支。

冲突问题

今天在服务器上git pull是出现以下错误:

error: Your local changes to the following files would be overwritten by merge:
Please, commit your changes or stash them before you can merge.
Aborting

处理方法如下:
如果希望保留生产服务器上所做的改动,仅仅并入新配置项:

git stash
git pull
git stash pop

然后可以使用git diff -w +文件名 来确认代码自动合并的情况.
如果希望用代码库中的文件完全覆盖本地工作版本. 方法如下:

git reset --hard
git pull

push异常

在使用Git Push代码到数据仓库时,提示如下错误:

[remote rejected] master -> master (branch is currently checked out)
remote: error: refusing to update checked out branch: refs/heads/master
remote: error: By default, updating the current branch in a non-bare repository
remote: error: is denied, because it will make the index and work tree inconsistent
remote: error: with what you pushed, and will require 'git reset --hard' to match
remote: error: the work tree to HEAD.
remote: error: You can set 'receive.denyCurrentBranch' configuration variable to
remote: error: 'ignore' or 'warn' in the remote repository to allow pushing into
remote: error: its current branch; however, this is not recommended unless you
remote: error: arranged to update its work tree to match what you pushed in some
remote: error: other way.
remote: error: To squelch this message and still keep the default behaviour, set
remote: error: 'receive.denyCurrentBranch' configuration variable to 'refuse'.
To git@192.168.1.X:/var/git.server/.../web
![remote rejected] master -> master (branch is currently checked out)
error: failed to push some refs to 'git@192.168.1.X:/var/git.server/.../web'

这是由于git默认拒绝了push操作,需要进行设置,修改.git/config添加如下代码:

[receive]
denyCurrentBranch = ignore

注意上面修改的是代码仓库的config,而不是本地分支的config
在初始化远程仓库时最好使用 git --bare init 而不要使用git init
如果使用了git init初始化,则远程仓库的目录下,也包含work tree,当本地仓库向远程仓库push时, 如果远程仓库正在push的分支上(如果当时不在push的分支,就没有问题), 那么push后的结果不会反应在work tree上, 也即在远程仓库的目录下对应的文件还是之前的内容,必须得使用git reset --hard才能看到push后的内容
