# Git Configuration Fix for Trackio Space Deployment

## Issue Identified

The Trackio Space deployment was failing with the error:
```
❌ Error uploading files: Command '['git', 'commit', '-m', 'Initial Trackio Space setup']' returned non-zero exit status 128.
```

This error occurs because git requires a user identity (email and name) to be configured before making commits. The deployment script was creating a temporary directory and initializing a git repository, but wasn't configuring the git user identity in that temporary directory.

## Root Cause

### **Problem**: Git Identity Not Configured in Temporary Directory

When the deployment script:
1. Creates a temporary directory
2. Changes to that directory (`os.chdir(temp_dir)`)
3. Initializes a git repository (`git init`)
4. Tries to commit (`git commit`)

The git repository in the temporary directory doesn't inherit the git configuration from the main directory, so it has no user identity configured.

### **Solution**: Configure Git Identity in Temporary Directory

The fix involves explicitly configuring git user identity in the temporary directory before attempting to commit.

## Fixes Applied

### 1. **Enhanced TrackioSpaceDeployer Constructor**

**Before**:
```python
def __init__(self, space_name: str, username: str, token: str):
    self.space_name = space_name
    self.username = username
    self.token = token
```

**After**:
```python
def __init__(self, space_name: str, username: str, token: str, git_email: str = None, git_name: str = None):
    self.space_name = space_name
    self.username = username
    self.token = token
    
    # Git configuration
    self.git_email = git_email or f"{username}@huggingface.co"
    self.git_name = git_name or username
```

### 2. **Git Configuration in upload_files_to_space Method**

**Added to the method**:
```python
# Configure git user identity for this repository
try:
    # Try to get existing git config
    result = subprocess.run(["git", "config", "--global", "user.email"], capture_output=True, text=True)
    if result.returncode == 0 and result.stdout.strip():
        git_email = result.stdout.strip()
    else:
        git_email = self.git_email
    
    result = subprocess.run(["git", "config", "--global", "user.name"], capture_output=True, text=True)
    if result.returncode == 0 and result.stdout.strip():
        git_name = result.stdout.strip()
    else:
        git_name = self.git_name
    
except Exception:
    # Fallback to default values
    git_email = self.git_email
    git_name = self.git_name

# Set git config for this repository
subprocess.run(["git", "config", "user.email", git_email], check=True, capture_output=True)
subprocess.run(["git", "config", "user.name", git_name], check=True, capture_output=True)

print(f"✅ Configured git with email: {git_email}, name: {git_name}")
```

### 3. **Updated Main Function**

**Enhanced to accept git configuration**:
```python
def main():
    # Get user input
    username = input("Enter your Hugging Face username: ").strip()
    space_name = input("Enter Space name (e.g., trackio-monitoring): ").strip()
    token = input("Enter your Hugging Face token: ").strip()
    
    # Get git configuration (optional)
    git_email = input("Enter your git email (optional, press Enter for default): ").strip()
    git_name = input("Enter your git name (optional, press Enter for default): ").strip()
    
    # Create deployer with git config
    deployer = TrackioSpaceDeployer(space_name, username, token, git_email, git_name)
```

### 4. **Updated Launch Script**

**Enhanced to pass git configuration**:
```bash
# Create deployment script input
cat > deploy_input.txt << EOF
$HF_USERNAME
$TRACKIO_SPACE_NAME
$HF_TOKEN
$GIT_EMAIL
$HF_USERNAME
EOF
```

## Testing the Fix

### **Run Git Configuration Tests**
```bash
python tests/test_git_config_fix.py
```

Expected output:
```
🚀 Testing Git Configuration Fix
========================================
🔍 Testing git configuration in temporary directory...
✅ Created temp directory: /tmp/tmp_xxxxx
✅ Initialized git repository
✅ Git email configured correctly
✅ Git name configured correctly
✅ Git commit successful
✅ Cleanup successful

🔍 Testing deployment script git configuration...
✅ Git email set correctly
✅ Git name set correctly

🔍 Testing git configuration fallback...
✅ Default git email set correctly
✅ Default git name set correctly

🔍 Testing git commit with configuration...
✅ Created temp directory: /tmp/tmp_xxxxx
✅ Git commit successful with configuration
✅ Cleanup successful

📊 Test Results: 4/4 tests passed
✅ All git configuration tests passed! The deployment should work correctly.
```

## Files Modified

### **Core Deployment Files**
1. **`scripts/trackio_tonic/deploy_trackio_space.py`**
   - Enhanced constructor to accept git configuration
   - Added git configuration in upload_files_to_space method
   - Updated main function to accept git parameters
   - Added fallback mechanisms for git configuration

### **Launch Script**
2. **`launch.sh`**
   - Updated to pass git configuration to deployment script
   - Enhanced input file creation with git parameters

### **Testing**
3. **`tests/test_git_config_fix.py`**
   - Comprehensive testing of git configuration
   - Tests for temporary directory git setup
   - Tests for deployment script git handling
   - Tests for fallback behavior

## Benefits of the Fix

### **1. Reliable Git Commits**
- Git user identity properly configured in temporary directory
- No more "exit status 128" errors
- Successful commits and pushes to Hugging Face Spaces

### **2. Flexible Configuration**
- Accepts custom git email and name
- Falls back to sensible defaults
- Works with existing git configuration

### **3. Better Error Handling**
- Graceful fallback to default values
- Clear error messages and logging
- Robust configuration validation

### **4. Professional Setup**
- Uses user's actual email address when provided
- Maintains proper git attribution
- Follows git best practices

## Usage Instructions

### **1. Test the Fix**
```bash
python tests/test_git_config_fix.py
```

### **2. Deploy with Git Configuration**
```bash
python scripts/trackio_tonic/deploy_trackio_space.py
```

When prompted:
- Enter your HF username
- Enter space name
- Enter your HF token
- Enter your git email (or press Enter for default)
- Enter your git name (or press Enter for default)

### **3. Use with Launch Script**
```bash
./launch.sh
```

The launch script will automatically pass the git configuration to the deployment script.

## Troubleshooting

### **Common Issues**

#### **1. Git Configuration Still Fails**
```bash
# Check if git is properly configured
git config --list

# Set git config manually if needed
git config --global user.email "[email protected]"
git config --global user.name "Your Name"
```

#### **2. Permission Issues**
```bash
# Check HF token permissions
hf whoami

# Verify token has write access
hf repo create test-repo --type space
```

#### **3. Space Creation Fails**
```bash
# Check if space name is available
# Try a different space name
# Verify HF token is valid
```

## Next Steps

1. **Test the fix**: Run the git configuration tests
2. **Deploy a test space**: Use the updated deployment script
3. **Verify deployment**: Check that the space is created successfully
4. **Use in production**: Deploy your actual Trackio Space

The git configuration fix should resolve the deployment issues and allow successful Trackio Space creation! 🚀
