在wchar_support分支中执行更改

Jerry正在wchar_support分支上工作。他更改了功能的名称，并在测试后提交更改。

[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

验证代码后，他提交更改。

在主分支中执行更改

同时，在master分支中，Tom还更改了相同函数的名称，并将其更改推送到master分支。

解决冲突

Tom希望了解Jerry在其私有分支上正在做什么，因此，他尝试从wchar_support分支中提取最新更改，但是Git终止操作并显示以下错误消息。

[tom@CentOS src]$ git pull origin wchar_support

上面的命令产生以下结果-

解决冲突

从错误消息中可以明显看出src / string_operations.c中存在冲突。他运行git diff命令以查看更多详细信息。

[tom@CentOS src]$ git diff

上面的命令产生以下结果-

diff --cc src/string_operations.c

由于Tom和Jerry都更改了同一函数的名称，因此Git处于混乱状态，它要求用户手动解决冲突。

Tom决定保留Jerry建议的函数名称，但他保留他自己添加的注释。删除冲突标记后，git diff将如下所示。

[tom@CentOS src]$ git diff

上面的命令产生以下结果。

Tom修改了文件后，必须先提交这些更改，然后才能提交更改。

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

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

汤姆解决了冲突，现在拉操作将成功。
