对付冲突

Tom想看，Jerry 在他的私人分支做什么？这就是为什么他试图从wchar_support分支把最新的修改，但Git 放弃操作在得到错误消息后。

解决冲突

从错误消息很显然知道，是有冲突的在src/string_operations.c。他运行 git diff 命令查看进一步的细节。

[tom@CentOS src]$ git diff

由于Tom 和Jerry 在相同的功能更改的名称，Git不知道如何去做，因此这就是为什么它要求用户手动解决冲突。

Tom 决定保用 Jerry 建议的函数名，但他使用原来注释，因为这是他加入的。删除冲突标记混帐后差异会看起来像这样。

Tom 修改过的文件，他先提交这些更改后，他就可以推送了。

[tom@CentOS src]$ git commit -a -m 'Resolved conflict'

Tom 已经解决冲突，现在推送操作将成功。
