如何解决failed to push some refs to git

在git pull的过程中，如果有冲突，那么除了冲突的文件之外，其它的文件都会做为staged区的文件保存起来。

重现：

$ git pull

Pull is not possible because you have unmerged files.
Please, fix them up in the work tree, and then use 'git add/rm '
as appropriate to mark resolution, or use ‘git commit -a’.

通过git status你会发现下面古怪的事情：

zhonghua@pts/ttys000 $ git status
#On branch sns
#Your branch and ‘snsconnect/sns’ have diverged,
#and have 1 and 52 different commit(s) each, respectively.

#Changes to be committed:

#new file: src/config/features_daodao.ini
#new file: src/config/services.xml
#new file: src/config/svnroot/hooks/mailer.conf
#new file: src/config/svnroot/hooks/mailer.py
#new file: src/config/svnroot/hooks/post-commit
#new file: src/config/svnroot/hooks/pre-commit
#new file: src/config/svnroot/hooks/prerelease_notifications.py
#new file: src/config/svnroot/hooks/run_checks.py
…….

#Untracked files:
#(use “git add …” to include in what will be committed)

#_build/
#css/combined/
#css/gen/
#daodao-site.patch
#daodao-site.patch1
#js/combined/
#js/gen/
#lib/weibo/
#src/bin/

Pull is not possible because you have unmerged files.

解决(亲测通过)：

1.pull会使用git merge导致冲突，需要将冲突的文件resolve掉 git add -u, git commit之后才能成功pull.

2.如果想放弃本地的文件修改，可以使用git reset --hard FETCH_HEAD，FETCH_HEAD表示上一次成功git pull之后形成的commit点。然后git pull.
注意：

git merge会形成MERGE-HEAD(FETCH-HEAD) 。git push会形成HEAD这样的引用。HEAD代表本地最近成功push后形成的引用。
