Git 多人协作(1)
一.Git标签管理
在git中，我们可以对某次commit进行标识，这就类似取了一个别名
例如在项目的最后一个版本的commit起名叫v1.0
除此之外，tag也可以相对于较难记住的commitID，更快的回退
1.标签管理实操
标签默认是对最新的提交进行。
git tag name
我们可以看.git目录中，refs目录中出现了我们刚才创建的tag v1.0
wujiahao@VM-12-14-ubuntu:~/gitcode$ git tag v1.0
wujiahao@VM-12-14-ubuntu:~/gitcode$ git tag

删除标签
git tag -d v1.0
wujiahao@VM-12-14-ubuntu:~/gitcode$ git tag -d v1.0
Deleted tag 'v1.0' (was dcf05d4)

v0.8
v0.9以上的操作都是对本地仓库标签的操作，当然我们也可以将标签的修改推送到远程仓库。
查看我们当前的远端仓库，是没有标签的。

二.Git多人协作实操
我们已经学习了大部分的Git操作，我们可以试着模拟一下多人协作开发的场景。
1.实操模拟
我们需要实现以下目标。为此，我们需要多用户对文件进行协作，这里的用户1为Linux用户，用户2为Windows用户。
由于我们不方便直接在master分支上操作，所以我们的操作是：在远程仓库创建一个新分支dev，两个用户将文件提交至dev，最后处理完冲突后再合并到master分支。
当前的状态
在执行pull操作前用户1的本地仓库状态
wujiahao@VM-12-14-ubuntu:~/linux-fundamentals-learning$ git branch
* master
wujiahao@VM-12-14-ubuntu:~/linux-fundamentals-learning$ git branch -rorigin/HEAD -> origin/masterorigin/master
因为远端此时创建了分支dev，我们拉取远端
wujiahao@VM-12-14-ubuntu:~/linux-fundamentals-learning$ git pull
From https://gitee.com/wjhwujiahao/linux-fundamentals-learning* [new branch] dev -> origin/dev
Already up to date.wujiahao@VM-12-14-ubuntu:~/linux-fundamentals-learning$ git branch -a
* masterremotes/origin/HEAD -> origin/masterremotes/origin/devremotes/origin/master
在用户1的本地创建dev分支并追踪远端的dev分支
wujiahao@VM-12-14-ubuntu:~/linux-fundamentals-learning$ git checkout -b dev origin/dev
Branch 'dev' set up to track remote branch 'dev' from 'origin'.
Switched to a new branch 'dev'此时可以查看到已追踪成功
wujiahao@VM-12-14-ubuntu:~/linux-fundamentals-learning$ git branch -vv
* dev c68d4e6 [origin/dev] add ignoremaster c68d4e6 [origin/master] add ignore
用户1向test.txt写入aaa，并add，commit，push。
wujiahao@VM-12-14-ubuntu:~/linux-fundamentals-learning$ git push
Username for 'https://gitee.com': wjhwujiahao

remote: Set trace flag 9f49ae86
To https://gitee.com/wjhwujiahao/linux-fundamentals-learning.gitc68d4e6..1d9f627 dev -> dev此时可以查看到，远端的dev分支已经有了我们的修改
此时用户1的准备工作已经做好，我们开始做用户2的准备工作
首先创建一个文件夹，在该文件夹下克隆仓库。
此时的状态
在当前目录下右键，选择用powershell打开。
可以查看当前用户2的仓库分支状态
创建用户2的本地dev分支并追踪
PS D:\git\linux-fundamentals-learning> git checkout -b dev origin/dev
branch 'dev' set up to track 'origin/dev'.
Switched to a new branch 'dev'此时我们执行push发现是有问题的。
这是因为发生了冲突，我们需要手动消除并push。
最后一步，合并远端master和dev
在gitee中，我们可以看到提交的各种信息。
