在wchar_support分支中执行更改

Jerry正在研究 wchar_support 分支。他更改了函数的名称,经过测试,他提交了更改。

[jerry@CentOS src]$ git branch
 master
* wchar_support
[jerry@CentOS src]$ git diff

上面的命令产生以下结果:

diff --git a/src/string_operations.c b/src/string_operations.c

在验证代码后,他提交了他的更改。

wchar_support 分支上,Jerry为宽字符串实现了strchr函数。经过测试,他提交并将更改推送到 wchar_support 分支。

解决冲突

Tom希望看到Jerry在他的私有分支上做了什么,所以他试图从 wchar_support 分支中提取最新的更改,但是Git使用以下错误消息中止操作。

[tom@CentOS src]$ git pull origin wchar_support

上面的命令产生以下结果:

解决冲突

从错误消息中可以清楚地看到src / string_operations.c中存在冲突。他运行git diff命令来查看更多详细信息。

[tom@CentOS src]$ git diff

上面的命令产生以下结果:

由于Tom和Jerry都更改了相同功能的名称,因此Git处于混乱状态,并要求用户手动解决冲突。

Tom决定保留Jerry建议的功能名称,但是他保留了由他添加的评论。删除冲突标记后,git diff将如下所示。

[tom@CentOS src]$ git diff

由于Tom修改了文件,他必须先提交这些更改,然后再进行更改。

[tom@CentOS src]$ git commit -a -m 'Resolved conflict'
[master 6b1ac36] Resolved conflict

[tom@CentOS src]$ git pull origin wchar_support.

Tom解决了冲突,现在拉动操作将成功。
