Git 删除大文件后进行分支瘦身

指令

# Make a fresh clone of YOUR_REPO
git clone YOUR_REPO
cd YOUR_REPO

# Create tracking branches of all branches
for remote in `git branch -r | grep -v /HEAD`; do git checkout --track $remote ; done

# Remove DIRECTORY_NAME from all commits, then remove the refs to the old commits
# (repeat these two commands for as many directories that you want to remove)
git filter-branch --index-filter 'git rm -rf --cached --ignore-unmatch DIRECTORY_NAME/' --prune-empty --tag-name-filter cat -- --all
git for-each-ref --format="%(refname)" refs/original/ | xargs -n 1 git update-ref -d

# Ensure all old refs are fully removed
rm -Rf .git/logs .git/refs/original

# Perform a garbage collection to remove commits with no refs
git gc --prune=all --aggressive

# Force push all branches to overwrite their history
# (use with caution!)
git push origin --all --force
git push origin --tags --force

git push origin 报错

error: failed to push some refs to 'ssh://code.xxx.com:10579/xxx/xxxx.git'

如果有如上报错 则需要在 GitLab 项目中的 Settings--Repository--Protected Branches 将保护分支unprotect
