转移gitlab仓库到gerrit仓库

由于gerrit仓库可以配置权限，所以会比gitlab仓库多一些分支。

#1. git clone Gerrit空仓库
git clone "http://xxx@gerrit.xxxx.com:80/a/reponame"

#2. git remote set-url gitlab_url (旧仓库)
git remote set-url origin "https://xxx@git-server.xxx.ai/reponame.git"

#3. 拉取所有分支到本地
git fetch
git checkout master
git pull --allow-unrelated-histories


setopt interactivecomments
git branch -r > ../branch.txt
let count=0
while read br;
do
 let count=$count+1
 # echo "$count--$br"
 if [ $count -eq 1 ];then
  continue;
 fi
 br=`echo $br|sed -r "s/.*origin\/(.*)$/\1/g"`
 echo "==current branch : $br"
 git checkout "$br"
done < ../branch.txt

#4. git pull –all –allow-unrelated-histories#指定允许拉取不相关的代码过来Merge, 有多个分支时，要把多个分支都拉下来，注意用户名: git config username#注释: git pull = git fetch + git merge
git pull --all --allow-unrelated-historie

#5. git remote set-url Gerrit_url#(指定新 Gerrit 代码库的地址)
git remote set-url origin "http://xxx@gerrit.xxxx.com:80/a/reponame"

#6. git push -u origin –all#git push -u origin –tags#把代码推送给 Gerrit 仓库
git push --all ; git push --tags
