Git 학습 및 훈련

gitlab 에 서 는 누구나 fork 원 격 으로 자신의 디 렉 터 리 에 갈 라 놓 은 다음 자신의 디 렉 터 리 에서 개발 하고 코드 를 원 격 창고 에 업로드 한 다음 gitlab 서버 를 통 해 merge request 를 시작 하여 메 인 창고 에 동기 화 해 야 합 니 다.git 관련 조작 을 빨리 파악 하기 위해 훈련 을 설정 합 니 다. 다음 과 같 습 니 다.
원 격 창 고 를 player 로 가정 합 니 다.oop, 로 컬 복제 후 myplayer_oop, 원 격 창 고 는 로 컬 업데이트 보다 원 격 코드 를 로 컬 로 동기 화 해 야 합 니 다. 여 기 는 git pull 방식 을 사용 하지 않 고 다음 과 같은 방법 을 사용 합 니 다. 아래 명령 을 점차적으로 사용 하 는 것 이 목적 입 니 다.

원 격 분기 git remote add 증가

원 격 코드 git fetch 동기 화

git branch 사용

git format-patch

git apply 사용

git am 사용

git st

git log

git push

다음은 실제 조작 과정 이다.

On branch master
Your branch is behind 'origin/master' by 6 commits, and can be fast-forwarded.
  (use "git pull" to update your local branch)

#获取主仓库内容
root@liufei-VirtualBox:/home/liufei/learngit/abc# git fetch upstream 
From pms.lemon.com:player/player_oop
 * [new branch]      master     -> upstream/master

#创建并切换到fork分支
root@liufei-VirtualBox:/home/liufei/learngit/abc# git checkout -b fork
Switched to a new branch 'fork'

#将远程主仓库中同步到fork分支上，这里使用是rebase
root@liufei-VirtualBox:/home/liufei/learngit/abc# git rebase upstream/master 
First, rewinding head to replay your work on top of it...
Fast-forwarded fork to upstream/master.

#同步完成后的fork分支，对比master分支，创建patch文件，并放置到patch目录下。
