Frontend Slider Component

Git - Distributed Version Control System

Advantages: Git clients can temporarily serve as servers, and Git servers can be deployed in clusters.

Three Git Areas

Working directory, staging area, repository

Basic Commands

/*
1. View command help: git command -h
2. Clear terminal: clear 
3. Initialize repository: git init /path/to/repo
4. Set global username and email: git config --global user.name 'username', git config --global user.email 'email'
5. Set local repo username and email: git config user.name 'username', git config user.email 'email'
6. Undo working directory changes: git checkout .
7. Move from staging back to working: git reset HEAD .
8. View detailed logs: git log, view brief logs: git reflog
9. Revert to specific commit: git reset --hard commit_hash
*/

Setting Up Ignore Files

1. Files or folders matching patterns in ignore files will be filtered out by Git
2. /path/to/project/\_\_pycache\_\_/ - Cache folder generated by imports
3. /path/to/logs/app.log needs filtering, but /path/to/logs does not

/*
// /path/to/repository/.gitignore
# Empty folders are ignored by default
temp_file.txt
/file_at_root.txt
*pattern*
*/

Branch Management Commands

/*
git branch feature_branch     // Create feature_branch from current branch, remains on current branch

git branch                  // View local branches

git branch --all            // View local and remote branches

git checkout feature_branch // Switch from current to feature_branch

git branch -d feature_branch // Delete feature_branch

git merge feature_dev       // Merge feature_dev into current branch
*/

Remote Repository Management

/*
git remote add origin_repo git@host.com:user/repo.git  // Link local to remote via SSH, origin_repo as alias

git remote --verbose        // View all remote link details

git pull origin_repo dev    // Sync remote dev to local dev
git push origin_repo main   // Push local main to remote main

git remote remove origin_repo // Remove link

1. Generate key pair: ssh-keygen -t rsa -C "identifier"
2. View public key: cat ~/.ssh/id_rsa.pub
3. Add public key to account

git clone git@host.com:user/repo.git  // Clone remote to local

Force remote rollback: 1. git pull origin_repo dev 2. git reset --hard hash 3. git push -f origin_repo dev
*/

Code Conflicts

Version and file conflicts are automatically resolved by Git.

Manual conflict resolution: Open conflicted files, integrate conflicting code, then re-pull, finally push.

Always pull before each push until no conflicts remain, then push.

Merging Online Repository Branches via Gitee

Select Pull Request to perform operations

• Regular branches: Branches where project members (developer-level permissions and above) can push
• Protected branches: Branches where only project administrators can push
• Read-only branches: Branches where no one (including administrators) can push
