* Update s3tests.yml

* Update s3tests.yml

* Update s3tests.conf

* Update s3tests.conf

* address test errors

* address test errors

With these fixes, the s3-tests should now:
✅ Return InvalidBucketState (409 Conflict) for object lock operations on invalid buckets
✅ Return MalformedXML for invalid retention configurations
✅ Include VersionId in response headers when available
✅ Return proper HTTP status codes (403 Forbidden for retention mode changes)
✅ Handle all object lock validation errors consistently

* fixes

With these comprehensive fixes, the s3-tests should now:
✅ Return InvalidBucketState (409 Conflict) for object lock operations on invalid buckets
✅ Return InvalidRetentionPeriod for invalid retention periods
✅ Return MalformedXML for malformed retention configurations
✅ Include VersionId in response headers when available
✅ Return proper HTTP status codes for all error conditions
✅ Handle all object lock validation errors consistently
The workflow should now pass significantly more object lock tests, bringing SeaweedFS's S3 object lock implementation much closer to AWS S3 compatibility standards.

* fixes

With these final fixes, the s3-tests should now:
✅ Return MalformedXML for ObjectLockEnabled: 'Disabled'
✅ Return MalformedXML when both Days and Years are specified in retention configuration
✅ Return InvalidBucketState (409 Conflict) when trying to suspend versioning on buckets with object lock enabled
✅ Handle all object lock validation errors consistently with proper error codes

* constants and fixes

✅ Return InvalidRetentionPeriod for invalid retention values (0 days, negative years)
✅ Return ObjectLockConfigurationNotFoundError when object lock configuration doesn't exist
✅ Handle all object lock validation errors consistently with proper error codes

* fixes

✅ Return MalformedXML when both Days and Years are specified in the same retention configuration
✅ Return 400 (Bad Request) with InvalidRequest when object lock operations are attempted on buckets without object lock enabled
✅ Handle all object lock validation errors consistently with proper error codes

* fixes

✅ Return 409 (Conflict) with InvalidBucketState for bucket-level object lock configuration operations on buckets without object lock enabled
✅ Allow increasing retention periods and overriding retention with same/later dates
✅ Only block decreasing retention periods without proper bypass permissions
✅ Handle all object lock validation errors consistently with proper error codes

* fixes

✅ Include VersionId in multipart upload completion responses when versioning is enabled
✅ Block retention mode changes (GOVERNANCE ↔ COMPLIANCE) without bypass permissions
✅ Handle all object lock validation errors consistently with proper error codes
✅ Pass the remaining object lock tests

* fix tests

* fixes

+# SeaweedFS Telemetry Server Deployment
+
+This document describes how to deploy the SeaweedFS telemetry server to a remote server using GitHub Actions.
+
+## Prerequisites
+
+1. A remote Linux server with:
+   - SSH access
+   - systemd (for service management)
+   - Optional: Prometheus and Grafana (for monitoring)
+
+2. GitHub repository secrets configured (see [Setup GitHub Secrets](#setup-github-secrets) below):
+   - `TELEMETRY_SSH_PRIVATE_KEY`: SSH private key for accessing the remote server
+   - `TELEMETRY_HOST`: Remote server hostname or IP address
+   - `TELEMETRY_USER`: Username for SSH access
+
+## Setup GitHub Secrets
+
+Before using the deployment workflow, you need to configure the required secrets in your GitHub repository.
+
+### Step 1: Generate SSH Key Pair
+
+On your local machine, generate a new SSH key pair specifically for deployment:
+
+```bash
+# Generate a new SSH key pair
+ssh-keygen -t ed25519 -C "seaweedfs-telemetry-deploy" -f ~/.ssh/seaweedfs_telemetry_deploy
+
+# This creates two files:
+# ~/.ssh/seaweedfs_telemetry_deploy     (private key)
+# ~/.ssh/seaweedfs_telemetry_deploy.pub (public key)
+```
+
+### Step 2: Configure Remote Server
+
+Copy the public key to your remote server:
+
+```bash
+# Copy public key to remote server
+ssh-copy-id -i ~/.ssh/seaweedfs_telemetry_deploy.pub user@your-server.com
+
+# Or manually append to authorized_keys
+cat ~/.ssh/seaweedfs_telemetry_deploy.pub | ssh user@your-server.com "mkdir -p ~/.ssh && cat >> ~/.ssh/authorized_keys"
+```
+
+Test the SSH connection:
+
+```bash
+# Test SSH connection with the new key
+ssh -i ~/.ssh/seaweedfs_telemetry_deploy user@your-server.com "echo 'SSH connection successful'"
+```
+
+### Step 3: Add Secrets to GitHub Repository
+
+1. Go to your GitHub repository
+2. Click on **Settings** tab
+3. In the sidebar, click **Secrets and variables** → **Actions**
+4. Click **New repository secret** for each of the following:
+
+#### TELEMETRY_SSH_PRIVATE_KEY
+
+```bash
+# Display the private key content
+cat ~/.ssh/seaweedfs_telemetry_deploy
+```
+
+- **Name**: `TELEMETRY_SSH_PRIVATE_KEY`
+- **Value**: Copy the entire private key content, including the `-----BEGIN OPENSSH PRIVATE KEY-----` and `-----END OPENSSH PRIVATE KEY-----` lines
+
+#### TELEMETRY_HOST
+
+- **Name**: `TELEMETRY_HOST`
+- **Value**: Your server's hostname or IP address (e.g., `telemetry.example.com` or `192.168.1.100`)
+
+#### TELEMETRY_USER
+
+- **Name**: `TELEMETRY_USER`
+- **Value**: The username on the remote server (e.g., `ubuntu`, `deploy`, or your username)
+
+### Step 4: Verify Configuration
+
+Create a simple test workflow or manually trigger the deployment to verify the secrets are working correctly.
+
+### Security Best Practices
+
+1. **Dedicated SSH Key**: Use a separate SSH key only for deployment
+2. **Limited Permissions**: Create a dedicated user on the remote server with minimal required permissions
+3. **Key Rotation**: Regularly rotate SSH keys
+4. **Server Access**: Restrict SSH access to specific IP ranges if possible
+
+### Example Server Setup
+
+If you're setting up a new server, here's a basic configuration:
+
+```bash
+# On the remote server, create a dedicated user for deployment
+sudo useradd -m -s /bin/bash seaweedfs-deploy
+sudo usermod -aG sudo seaweedfs-deploy  # Only if sudo access is needed
+
+# Switch to the deployment user
+sudo su - seaweedfs-deploy
+
+# Create SSH directory
+mkdir -p ~/.ssh
+chmod 700 ~/.ssh
+
+# Add your public key (paste the content of seaweedfs_telemetry_deploy.pub)
+nano ~/.ssh/authorized_keys
+chmod 600 ~/.ssh/authorized_keys
+```
+
+### Troubleshooting
+
+#### SSH Connection Issues
+
+```bash
+# Test SSH connection manually
+ssh -i ~/.ssh/seaweedfs_telemetry_deploy -v user@your-server.com
+
+# Check SSH key permissions
+ls -la ~/.ssh/seaweedfs_telemetry_deploy*
+# Should show: -rw------- for private key, -rw-r--r-- for public key
+```
+
+#### GitHub Actions Fails
+
+1. **Check secrets**: Ensure all three secrets are properly set in GitHub
+2. **Verify SSH key**: Make sure the entire private key (including headers/footers) is copied
+3. **Test connectivity**: Manually SSH to the server from your local machine
+4. **Check user permissions**: Ensure the remote user has necessary permissions
+
+## GitHub Actions Workflow
+
+The deployment workflow (`.github/workflows/deploy_telemetry.yml`) provides two main operations:
+
+### 1. First-time Setup
+
+Run this once to set up the remote server:
+
+1. Go to GitHub Actions in your repository
+2. Select "Deploy Telemetry Server" workflow
+3. Click "Run workflow"
+4. Check "Run first-time server setup"
+5. Click "Run workflow"
+
+This will:
+- Create necessary directories on the remote server
+- Set up systemd service configuration
+- Configure log rotation
+- Upload Grafana dashboard and Prometheus configuration
+- Enable the telemetry service (but not start it yet)
+
+**Note**: The setup only prepares the infrastructure. You need to run a deployment afterward to install and start the telemetry server.
+
+
+### 2. Deploy Updates
+
+To deploy updates, manually trigger deployment:
+1. Go to GitHub Actions in your repository
+2. Select "Deploy Telemetry Server" workflow
+3. Click "Run workflow"
+4. Check "Deploy telemetry server to remote server"
+5. Click "Run workflow"
+
+## Server Directory Structure
+
+After setup, the remote server will have:
+
+```
+~/seaweedfs-telemetry/
+├── bin/
+│   └── telemetry-server          # Binary executable
+├── logs/
+│   ├── telemetry.log            # Application logs
+│   └── telemetry.error.log      # Error logs
+├── data/                        # Data directory (if needed)
+├── grafana-dashboard.json       # Grafana dashboard configuration
+└── prometheus.yml               # Prometheus configuration
+```
+
+## Service Management
+
+The telemetry server runs as a systemd service:
+
+```bash
+# Check service status
+sudo systemctl status telemetry.service
+
+# View logs
+sudo journalctl -u telemetry.service -f
+
+# Restart service
+sudo systemctl restart telemetry.service
+
+# Stop/start service
+sudo systemctl stop telemetry.service
+sudo systemctl start telemetry.service
+```
+
+## Accessing the Service
+
+After deployment, the telemetry server will be available at:
+
+- **Dashboard**: `http://your-server:8353`
+- **API**: `http://your-server:8353/api/*`
+- **Metrics**: `http://your-server:8353/metrics`
+- **Health Check**: `http://your-server:8353/health`
+
+## Optional: Prometheus and Grafana Integration
+
+### Prometheus Setup
+
+1. Install Prometheus on your server
+2. Update `/etc/prometheus/prometheus.yml` to include:
+   ```yaml
+   scrape_configs:
+     - job_name: 'seaweedfs-telemetry'
+       static_configs:
+         - targets: ['localhost:8353']
+       metrics_path: '/metrics'
+   ```
+
+### Grafana Setup
+
+1. Install Grafana on your server
+2. Import the dashboard from `~/seaweedfs-telemetry/grafana-dashboard.json`
+3. Configure Prometheus as a data source pointing to your Prometheus instance
+
+## Troubleshooting
+
+### Deployment Fails
+
+1. Check GitHub Actions logs for detailed error messages
+2. Verify SSH connectivity: `ssh user@host`
+3. Ensure all required secrets are configured in GitHub
+
+### Service Won't Start
+
+1. Check service logs: `sudo journalctl -u telemetry.service`
+2. Verify binary permissions: `ls -la ~/seaweedfs-telemetry/bin/`
+3. Test binary manually: `~/seaweedfs-telemetry/bin/telemetry-server -help`
+
+### Port Conflicts
+
+If port 8353 is already in use:
+
+1. Edit the systemd service: `sudo systemctl edit telemetry.service`
+2. Add override configuration:
+   ```ini
+   [Service]
+   ExecStart=
+   ExecStart=/home/user/seaweedfs-telemetry/bin/telemetry-server -port=8354
+   ```
+3. Reload and restart: `sudo systemctl daemon-reload && sudo systemctl restart telemetry.service`
+
+## Security Considerations
+
+1. **Firewall**: Consider restricting access to telemetry ports
+2. **SSH Keys**: Use dedicated SSH keys with minimal permissions
+3. **User Permissions**: Run the service as a non-privileged user
+4. **Network**: Consider running on internal networks only
+
+## Monitoring
+
+Monitor the deployment and service health:
+
+- **GitHub Actions**: Check workflow runs for deployment status
+- **System Logs**: `sudo journalctl -u telemetry.service`
+- **Application Logs**: `tail -f ~/seaweedfs-telemetry/logs/telemetry.log`
+- **Health Endpoint**: `curl http://localhost:8353/health`
+- **Metrics**: `curl http://localhost:8353/metrics`

+# SeaweedFS Telemetry System
+
+A privacy-respecting telemetry system for SeaweedFS that collects cluster-level usage statistics and provides visualization through Prometheus and Grafana.
+
+## Features
+
+- **Privacy-First Design**: Uses in-memory cluster IDs (regenerated on restart), no personal data collection
+- **Prometheus Integration**: Native Prometheus metrics for monitoring and alerting
+- **Grafana Dashboards**: Pre-built dashboards for data visualization
+- **Protocol Buffers**: Efficient binary data transmission for optimal performance
+- **Opt-in Only**: Disabled by default, requires explicit configuration
+- **Docker Compose**: Complete monitoring stack deployment
+- **Automatic Cleanup**: Configurable data retention policies
+
+## Architecture
+
+```
+SeaweedFS Cluster → Telemetry Client → Telemetry Server → Prometheus → Grafana
+                       (protobuf)         (metrics)      (queries)
+```
+
+## Data Transmission
+
+The telemetry system uses **Protocol Buffers exclusively** for efficient binary data transmission:
+
+- **Compact Format**: 30-50% smaller than JSON
+- **Fast Serialization**: Better performance than text-based formats
+- **Type Safety**: Strong typing with generated Go structs
+- **Schema Evolution**: Built-in versioning support
+
+### Protobuf Schema
+
+```protobuf
+message TelemetryData {
+  string cluster_id = 1;           // In-memory generated UUID
+  string version = 2;              // SeaweedFS version
+  string os = 3;                   // Operating system
+  // Field 4 reserved (was features)
+  // Field 5 reserved (was deployment)
+  int32 volume_server_count = 6;   // Number of volume servers
+  uint64 total_disk_bytes = 7;     // Total disk usage
+  int32 total_volume_count = 8;    // Total volume count
+  int32 filer_count = 9;           // Number of filer servers
+  int32 broker_count = 10;         // Number of broker servers
+  int64 timestamp = 11;            // Collection timestamp
+}
+```
+
+## Privacy Approach
+
+- **No Personal Data**: No hostnames, IP addresses, or user information
+- **In-Memory IDs**: Cluster IDs are generated in-memory and change on restart
+- **Aggregated Data**: Only cluster-level statistics, no individual file/user data
+- **Opt-in Only**: Telemetry is disabled by default
+- **Transparent**: Open source implementation, clear data collection policy
+
+## Collected Data
+
+| Field | Description | Example |
+|-------|-------------|---------|
+| `cluster_id` | In-memory UUID (changes on restart) | `a1b2c3d4-...` |
+| `version` | SeaweedFS version | `3.45` |
+| `os` | Operating system and architecture | `linux/amd64` |
+| `volume_server_count` | Number of volume servers | `5` |
+| `total_disk_bytes` | Total disk usage across cluster | `1073741824` |
+| `total_volume_count` | Total number of volumes | `120` |
+| `filer_count` | Number of filer servers | `2` |
+| `broker_count` | Number of broker servers | `1` |
+| `timestamp` | When data was collected | `1640995200` |
+
+## Quick Start

+
+## Prometheus Metrics
+
+The telemetry server exposes these Prometheus metrics:
+
+### Cluster Metrics
+- `seaweedfs_telemetry_total_clusters`: Total unique clusters (30 days)
+- `seaweedfs_telemetry_active_clusters`: Active clusters (7 days)
+
+### Per-Cluster Metrics
+- `seaweedfs_telemetry_volume_servers{cluster_id, version, os}`: Volume servers per cluster
+- `seaweedfs_telemetry_disk_bytes{cluster_id, version, os}`: Disk usage per cluster  
+- `seaweedfs_telemetry_volume_count{cluster_id, version, os}`: Volume count per cluster
+- `seaweedfs_telemetry_filer_count{cluster_id, version, os}`: Filer servers per cluster
+- `seaweedfs_telemetry_broker_count{cluster_id, version, os}`: Broker servers per cluster
+- `seaweedfs_telemetry_cluster_info{cluster_id, version, os}`: Cluster metadata
+
+### Server Metrics
+- `seaweedfs_telemetry_reports_received_total`: Total telemetry reports received
+
+## API Endpoints
+
+### Data Collection
+```bash
+# Submit telemetry data (protobuf only)
+POST /api/collect
+Content-Type: application/x-protobuf
+[TelemetryRequest protobuf data]
+```
+
+### Statistics (JSON for dashboard/debugging)
+```bash
+# Get aggregated statistics
+GET /api/stats
+
+# Get recent cluster instances
+GET /api/instances?limit=100
+
+# Get metrics over time
+GET /api/metrics?days=30
+```
+
+### Monitoring
+```bash
+# Prometheus metrics
+GET /metrics
+```
+
+## Docker Deployment
+
+### Complete Stack (Recommended)
+
+```yaml
+# docker-compose.yml
+version: '3.8'
+services:
+  telemetry-server:
+    build: ./server
+    ports:
+      - "8080:8080"
+    command: ["-port=8080", "-dashboard=true", "-cleanup=24h"]
+    
+  prometheus:
+    image: prom/prometheus:latest
+    ports:
+      - "9090:9090"
+    volumes:
+      - ./prometheus.yml:/etc/prometheus/prometheus.yml
+      
+  grafana:
+    image: grafana/grafana:latest
+    ports:
+      - "3000:3000"
+    environment:
+      - GF_SECURITY_ADMIN_PASSWORD=admin
+    volumes:
+      - ./grafana-provisioning:/etc/grafana/provisioning
+      - ./grafana-dashboard.json:/var/lib/grafana/dashboards/seaweedfs.json
+```
+
+```bash
+# Deploy the stack
+docker-compose up -d
+
+# Scale telemetry server if needed
+docker-compose up -d --scale telemetry-server=3
+```
+
+### Server Only
+
+```bash
+# Build and run telemetry server
+cd server
+docker build -t seaweedfs-telemetry .
+docker run -p 8080:8080 seaweedfs-telemetry -port=8080 -dashboard=true
+```
+
+## Development
+
+### Protocol Buffer Development
+
+```bash
+# Generate protobuf code
+cd telemetry
+protoc --go_out=. --go_opt=paths=source_relative proto/telemetry.proto
+
+# The generated code is already included in the repository
+```
+
+### Build from Source
+
+```bash
+# Build telemetry server
+cd telemetry/server
+go build -o telemetry-server .
+
+# Build SeaweedFS with telemetry support
+cd ../..
+go build -o weed ./weed
+```
+
+### Testing
+
+```bash
+# Test telemetry server
+cd telemetry/server
+go test ./...
+
+# Test protobuf communication (requires protobuf tools)
+# See telemetry client code for examples
+```
+
+## Grafana Dashboard
+
+The included Grafana dashboard provides:
+
+- **Overview**: Total and active clusters, version distribution
+- **Resource Usage**: Volume servers and disk usage over time  
+- **Infrastructure**: Operating system distribution and server counts
+- **Growth Trends**: Historical growth patterns
+
+### Custom Queries
+
+```promql
+# Total active clusters
+seaweedfs_telemetry_active_clusters
+
+# Disk usage by version
+sum by (version) (seaweedfs_telemetry_disk_bytes)
+
+# Volume servers by operating system
+sum by (os) (seaweedfs_telemetry_volume_servers)
+
+# Filer servers by version
+sum by (version) (seaweedfs_telemetry_filer_count)
+
+# Broker servers across all clusters
+sum(seaweedfs_telemetry_broker_count)
+
+# Growth rate (weekly)
+increase(seaweedfs_telemetry_total_clusters[7d])
+```
+
+## Security Considerations
+
+- **Network Security**: Use HTTPS in production environments
+- **Access Control**: Implement authentication for Grafana and Prometheus
+- **Data Retention**: Configure appropriate retention policies
+- **Monitoring**: Monitor the telemetry infrastructure itself
+
+## Troubleshooting
+
+### Common Issues
+
+**SeaweedFS not sending data:**
+```bash
+# Check telemetry configuration
+weed master -h | grep telemetry
+
+# Verify connectivity
+curl -v http://your-telemetry-server:8080/api/collect
+```
+
+**Server not receiving data:**
+```bash
+# Check server logs
+docker-compose logs telemetry-server
+
+# Verify metrics endpoint
+curl http://localhost:8080/metrics
+```
+
+**Prometheus not scraping:**
+```bash
+# Check Prometheus targets
+curl http://localhost:9090/api/v1/targets
+
+# Verify configuration
+docker-compose logs prometheus
+```
+
+### Debugging
+
+```bash
+# Enable verbose logging in SeaweedFS
+weed master -v=2 -telemetry=true
+
+# Check telemetry server metrics
+curl http://localhost:8080/metrics | grep seaweedfs_telemetry
+
+# Test data flow
+curl http://localhost:8080/api/stats
+```

+# Erasure Coding Integration Tests
+
+This directory contains integration tests for the EC (Erasure Coding) encoding volume location timing bug fix.
+
+## The Bug
+
+The bug caused **double storage usage** during EC encoding because:
+
+1. **Silent failure**: Functions returned `nil` instead of proper error messages
+2. **Timing race condition**: Volume locations were collected **AFTER** EC encoding when master metadata was already updated
+3. **Missing cleanup**: Original volumes weren't being deleted after EC encoding
+
+This resulted in both original `.dat` files AND EC `.ec00-.ec13` files coexisting, effectively **doubling storage usage**.
+
+## The Fix
+
+The fix addresses all three issues:
+
+1. **Fixed silent failures**: Updated `doDeleteVolumes()` and `doEcEncode()` to return proper errors
+2. **Fixed timing race condition**: Created `doDeleteVolumesWithLocations()` that uses pre-collected volume locations
+3. **Enhanced cleanup**: Volume locations are now collected **BEFORE** EC encoding, preventing the race condition
+
+## Integration Tests
+
+### TestECEncodingVolumeLocationTimingBug
+The main integration test that:
+- **Simulates master timing race condition**: Tests what happens when volume locations are read from master AFTER EC encoding has updated the metadata
+- **Verifies fix effectiveness**: Checks for the "Collecting volume locations...before EC encoding" message that proves the fix is working
+- **Tests multi-server distribution**: Runs EC encoding with 6 volume servers to test shard distribution
+- **Validates cleanup**: Ensures original volumes are properly cleaned up after EC encoding
+
+### TestECEncodingMasterTimingRaceCondition
+A focused test that specifically targets the **master metadata timing race condition**:
+- **Simulates the exact race condition**: Tests volume location collection timing relative to master metadata updates
+- **Detects timing fix**: Verifies that volume locations are collected BEFORE EC encoding starts
+- **Demonstrates bug impact**: Shows what happens when volume locations are unavailable after master metadata update
+
+### TestECEncodingRegressionPrevention
+Regression tests that ensure:
+- **Function signatures**: Fixed functions still exist and return proper errors
+- **Timing patterns**: Volume location collection happens in the correct order
+
+## Test Architecture
+
+The tests use:
+- **Real SeaweedFS cluster**: 1 master server + 6 volume servers
+- **Multi-server setup**: Tests realistic EC shard distribution across multiple servers
+- **Timing simulation**: Goroutines and delays to simulate race conditions
+- **Output validation**: Checks for specific log messages that prove the fix is working
+
+## Why Integration Tests Were Necessary
+
+Unit tests could not catch this bug because:
+1. **Race condition**: The bug only occurred in real-world timing scenarios
+2. **Master-volume server interaction**: Required actual master metadata updates
+3. **File system operations**: Needed real volume creation and EC shard generation
+4. **Cleanup timing**: Required testing the sequence of operations in correct order
+
+The integration tests successfully catch the timing bug by:
+- **Testing real command execution**: Uses actual `ec.encode` shell command
+- **Simulating race conditions**: Creates timing scenarios that expose the bug
+- **Validating output messages**: Checks for the key "Collecting volume locations...before EC encoding" message
+- **Monitoring cleanup behavior**: Ensures original volumes are properly deleted
+
+## Running the Tests
+
+```bash
+# Run all integration tests
+go test -v
+
+# Run only the main timing test
+go test -v -run TestECEncodingVolumeLocationTimingBug
+
+# Run only the race condition test
+go test -v -run TestECEncodingMasterTimingRaceCondition
+
+# Skip integration tests (short mode)
+go test -v -short
+```
+
+## Test Results
+
+**With the fix**: Shows "Collecting volume locations for N volumes before EC encoding..." message
+**Without the fix**: No collection message, potential timing race condition
+
+The tests demonstrate that the fix prevents the volume location timing bug that caused double storage usage in EC encoding operations.

+# SeaweedFS FUSE Integration Testing Framework
+
+## Overview
+
+This directory contains a comprehensive integration testing framework for SeaweedFS FUSE operations. The current SeaweedFS FUSE tests are primarily performance-focused (using FIO) but lack comprehensive functional testing. This framework addresses those gaps.
+
+## ⚠️ Current Status
+
+**Note**: Due to Go module conflicts between this test framework and the parent SeaweedFS module, the full test suite currently requires manual setup. The framework files are provided as a foundation for comprehensive FUSE testing once the module structure is resolved.
+
+### Working Components
+- ✅ Framework design and architecture (`framework.go`)
+- ✅ Individual test file structure and compilation
+- ✅ Test methodology and comprehensive coverage
+- ✅ Documentation and usage examples
+- ⚠️ Full test suite execution (requires Go module isolation)
+
+### Verified Working Test
+```bash
+cd test/fuse_integration
+go test -v simple_test.go
+```
+
+## Current Testing Gaps Addressed
+
+### 1. **Limited Functional Coverage**
+- **Current**: Only basic FIO performance tests
+- **New**: Comprehensive testing of all FUSE operations (create, read, write, delete, mkdir, rmdir, permissions, etc.)
+
+### 2. **No Concurrency Testing**
+- **Current**: Single-threaded performance tests
+- **New**: Extensive concurrent operation tests, race condition detection, thread safety validation
+
+### 3. **Insufficient Error Handling**
+- **Current**: Basic error scenarios
+- **New**: Comprehensive error condition testing, edge cases, failure recovery
+
+### 4. **Missing Edge Cases**
+- **Current**: Simple file operations
+- **New**: Large files, sparse files, deep directory nesting, many small files, permission variations
+
+## Framework Architecture
+
+### Core Components
+
+1. **`framework.go`** - Test infrastructure and utilities
+   - `FuseTestFramework` - Main test management struct
+   - Automated SeaweedFS cluster setup/teardown
+   - FUSE mount/unmount management
+   - Helper functions for file operations and assertions
+
+2. **`basic_operations_test.go`** - Fundamental FUSE operations
+   - File create, read, write, delete
+   - File attributes and permissions
+   - Large file handling
+   - Sparse file operations
+
+3. **`directory_operations_test.go`** - Directory-specific tests
+   - Directory creation, deletion, listing
+   - Nested directory structures
+   - Directory permissions and rename operations
+   - Complex directory scenarios
+
+4. **`concurrent_operations_test.go`** - Concurrency and stress testing
+   - Concurrent file and directory operations
+   - Race condition detection
+   - High-frequency operations
+   - Stress testing scenarios
+
+## Key Features
+
+### Automated Test Environment
+```go
+framework := NewFuseTestFramework(t, DefaultTestConfig())
+defer framework.Cleanup()
+require.NoError(t, framework.Setup(DefaultTestConfig()))
+```
+
+- **Automatic cluster setup**: Master, Volume, Filer servers
+- **FUSE mounting**: Proper mount point management
+- **Cleanup**: Automatic teardown of all resources
+
+### Configurable Test Parameters
+```go
+config := &TestConfig{
+    Collection:   "test",
+    Replication:  "001", 
+    ChunkSizeMB:  8,
+    CacheSizeMB:  200,
+    NumVolumes:   5,
+    EnableDebug:  true,
+    MountOptions: []string{"-allowOthers"},
+}
+```
+
+### Rich Assertion Helpers
+```go
+framework.AssertFileExists("path/to/file")
+framework.AssertFileContent("file.txt", expectedContent)
+framework.AssertFileMode("script.sh", 0755)
+framework.CreateTestFile("test.txt", []byte("content"))
+```
+
+## Test Categories
+
+### 1. Basic File Operations
+- **Create/Read/Write/Delete**: Fundamental file operations
+- **File Attributes**: Size, timestamps, permissions
+- **Append Operations**: File appending behavior
+- **Large Files**: Files exceeding chunk size limits
+- **Sparse Files**: Non-contiguous file data
+
+### 2. Directory Operations  
+- **Directory Lifecycle**: Create, list, remove directories
+- **Nested Structures**: Deep directory hierarchies
+- **Directory Permissions**: Access control testing
+- **Directory Rename**: Move operations
+- **Complex Scenarios**: Many files, deep nesting
+
+### 3. Concurrent Operations
+- **Multi-threaded Access**: Simultaneous file operations
+- **Race Condition Detection**: Concurrent read/write scenarios
+- **Directory Concurrency**: Parallel directory operations
+- **Stress Testing**: High-frequency operations
+
+### 4. Error Handling & Edge Cases
+- **Permission Denied**: Access control violations
+- **Disk Full**: Storage limit scenarios
+- **Network Issues**: Filer/Volume server failures
+- **Invalid Operations**: Malformed requests
+- **Recovery Testing**: Error recovery scenarios
+
+## Usage Examples
+
+### Basic Test Run
+```bash
+# Build SeaweedFS binary
+make
+
+# Run all FUSE tests
+cd test/fuse_integration
+go test -v
+
+# Run specific test category
+go test -v -run TestBasicFileOperations
+go test -v -run TestConcurrentFileOperations
+```
+
+### Custom Configuration
+```go
+func TestCustomFUSE(t *testing.T) {
+    config := &TestConfig{
+        ChunkSizeMB:  16,           // Larger chunks
+        CacheSizeMB:  500,          // More cache
+        EnableDebug:  true,         // Debug output
+        SkipCleanup:  true,         // Keep files for inspection
+    }
+    
+    framework := NewFuseTestFramework(t, config)
+    defer framework.Cleanup()
+    require.NoError(t, framework.Setup(config))
+    
+    // Your tests here...
+}
+```
+
+### Debugging Failed Tests
+```go
+config := &TestConfig{
+    EnableDebug:  true,     // Enable verbose logging
+    SkipCleanup:  true,     // Keep temp files for inspection
+}
+```
+
+## Advanced Features
+
+### Performance Benchmarking
+```go
+func BenchmarkLargeFileWrite(b *testing.B) {
+    framework := NewFuseTestFramework(t, DefaultTestConfig())
+    defer framework.Cleanup()
+    require.NoError(t, framework.Setup(DefaultTestConfig()))
+    
+    b.ResetTimer()
+    for i := 0; i < b.N; i++ {
+        // Benchmark file operations
+    }
+}
+```
+
+### Custom Test Scenarios
+```go
+func TestCustomWorkload(t *testing.T) {
+    framework := NewFuseTestFramework(t, DefaultTestConfig())
+    defer framework.Cleanup()
+    require.NoError(t, framework.Setup(DefaultTestConfig()))
+    
+    // Simulate specific application workload
+    simulateWebServerWorkload(t, framework)
+    simulateDatabaseWorkload(t, framework)
+    simulateBackupWorkload(t, framework)
+}
+```
+
+## Integration with CI/CD
+

+// - The full framework (framework.go) has Go module conflicts with parent project
+// - This standalone version proves the concept works without those conflicts
+// - Once module issues are resolved, this can be removed or simplified
+//

+# SeaweedFS Message Queue Test Suite
+
+This directory contains test programs for SeaweedFS Message Queue (MQ) functionality, including message producers and consumers.
+
+## Prerequisites
+
+1. **SeaweedFS with MQ Broker and Agent**: You need a running SeaweedFS instance with MQ broker and agent enabled
+2. **Go**: Go 1.19 or later required for building the test programs
+
+## Quick Start
+
+### 1. Start SeaweedFS with MQ Broker and Agent
+
+```bash
+# Start SeaweedFS server with MQ broker and agent
+weed server -mq.broker -mq.agent -filer -volume
+
+# Or start components separately
+weed master
+weed volume -mserver=localhost:9333
+weed filer -master=localhost:9333
+weed mq.broker -filer=localhost:8888
+weed mq.agent -brokers=localhost:17777
+```
+
+### 2. Build Test Programs
+
+```bash
+# Build both producer and consumer
+make build
+
+# Or build individually
+make build-producer
+make build-consumer
+```
+
+### 3. Run Basic Test
+
+```bash
+# Run a basic producer/consumer test
+make test
+
+# Or run producer and consumer manually
+make consumer &  # Start consumer in background
+make producer    # Start producer
+```
+
+## Test Programs
+
+### Producer (`producer/main.go`)
+
+Generates structured messages and publishes them to a SeaweedMQ topic via the MQ agent.
+
+**Usage:**
+```bash
+./bin/producer [options]
+```
+
+**Options:**
+- `-agent`: MQ agent address (default: localhost:16777)
+- `-namespace`: Topic namespace (default: test)
+- `-topic`: Topic name (default: test-topic)
+- `-partitions`: Number of partitions (default: 4)
+- `-messages`: Number of messages to produce (default: 100)
+- `-publisher`: Publisher name (default: test-producer)
+- `-size`: Message size in bytes (default: 1024)
+- `-interval`: Interval between messages (default: 100ms)
+
+**Example:**
+```bash
+./bin/producer -agent=localhost:16777 -namespace=test -topic=my-topic -messages=1000 -interval=50ms
+```
+
+### Consumer (`consumer/main.go`)
+
+Consumes structured messages from a SeaweedMQ topic via the MQ agent.
+
+**Usage:**
+```bash
+./bin/consumer [options]
+```
+
+**Options:**
+- `-agent`: MQ agent address (default: localhost:16777)
+- `-namespace`: Topic namespace (default: test)
+- `-topic`: Topic name (default: test-topic)
+- `-group`: Consumer group name (default: test-consumer-group)
+- `-instance`: Consumer group instance ID (default: test-consumer-1)
+- `-max-partitions`: Maximum number of partitions to consume (default: 10)
+- `-window-size`: Sliding window size for concurrent processing (default: 100)
+- `-offset`: Offset type: earliest, latest, timestamp (default: latest)
+- `-offset-ts`: Offset timestamp in nanoseconds (for timestamp offset type)
+- `-filter`: Message filter (default: empty)
+- `-show-messages`: Show consumed messages (default: true)
+- `-log-progress`: Log progress every 10 messages (default: true)
+
+**Example:**
+```bash
+./bin/consumer -agent=localhost:16777 -namespace=test -topic=my-topic -group=my-group -offset=earliest
+```
+
+## Makefile Commands
+
+### Building
+- `make build`: Build both producer and consumer binaries
+- `make build-producer`: Build producer only
+- `make build-consumer`: Build consumer only
+
+### Running
+- `make producer`: Build and run producer
+- `make consumer`: Build and run consumer
+- `make run-producer`: Run producer directly with go run
+- `make run-consumer`: Run consumer directly with go run
+
+### Testing
+- `make test`: Run basic producer/consumer test
+- `make test-performance`: Run performance test (1000 messages, 8 partitions)
+- `make test-multiple-consumers`: Run test with multiple consumers
+
+### Cleanup
+- `make clean`: Remove build artifacts
+
+### Help
+- `make help`: Show detailed help
+
+## Configuration
+
+Configure tests using environment variables:
+
+```bash
+export AGENT_ADDR=localhost:16777
+export TOPIC_NAMESPACE=test
+export TOPIC_NAME=test-topic
+export PARTITION_COUNT=4
+export MESSAGE_COUNT=100
+export CONSUMER_GROUP=test-consumer-group
+export CONSUMER_INSTANCE=test-consumer-1
+```
+
+## Example Usage Scenarios
+
+### 1. Basic Producer/Consumer Test
+
+```bash
+# Terminal 1: Start consumer
+make consumer
+
+# Terminal 2: Run producer
+make producer MESSAGE_COUNT=50
+```
+
+### 2. Performance Testing
+
+```bash
+# Test with high throughput
+make test-performance
+```
+
+### 3. Multiple Consumer Groups
+
+```bash
+# Terminal 1: Consumer group 1
+make consumer CONSUMER_GROUP=group1
+
+# Terminal 2: Consumer group 2  
+make consumer CONSUMER_GROUP=group2
+
+# Terminal 3: Producer
+make producer MESSAGE_COUNT=200
+```
+
+### 4. Different Offset Types
+
+```bash
+# Consume from earliest
+make consumer OFFSET=earliest
+
+# Consume from latest
+make consumer OFFSET=latest
+
+# Consume from timestamp
+make consumer OFFSET=timestamp OFFSET_TS=1699000000000000000
+```
+
+## Troubleshooting
+
+### Common Issues
+
+1. **Connection Refused**: Make sure SeaweedFS MQ agent is running on the specified address
+2. **Agent Not Found**: Ensure both MQ broker and agent are running (agent requires broker)
+3. **Topic Not Found**: The producer will create the topic automatically on first publish
+4. **Consumer Not Receiving Messages**: Check if consumer group offset is correct (try `earliest`)
+5. **Build Failures**: Ensure you're running from the SeaweedFS root directory
+
+### Debug Mode
+
+Enable verbose logging:
+```bash
+# Run with debug logging
+GLOG_v=4 make producer
+GLOG_v=4 make consumer
+```
+
+### Check Broker and Agent Status
+
+```bash
+# Check if broker is running
+curl http://localhost:9333/cluster/brokers
+
+# Check if agent is running (if running as server)
+curl http://localhost:9333/cluster/agents
+
+# Or use weed shell
+weed shell -master=localhost:9333
+> mq.broker.list
+```
+
+## Architecture
+
+The test setup demonstrates:
+
+1. **Agent-Based Architecture**: Uses MQ agent as intermediary between clients and brokers
+2. **Structured Messages**: Messages use schema-based RecordValue format instead of raw bytes
+3. **Topic Management**: Creating and configuring topics with multiple partitions
+4. **Message Production**: Publishing structured messages with keys for partitioning
+5. **Message Consumption**: Consuming structured messages with consumer groups and offset management
+6. **Load Balancing**: Multiple consumers in same group share partition assignments
+7. **Fault Tolerance**: Graceful handling of agent and broker failures and reconnections
+
+## Files
+
+- `producer/main.go`: Message producer implementation
+- `consumer/main.go`: Message consumer implementation
+- `Makefile`: Build and test automation
+- `README.md`: This documentation
+- `bin/`: Built binaries (created during build)
+
+## Next Steps
+
+1. Modify the producer to send structured data using `RecordType`
+2. Implement message filtering in the consumer
+3. Add metrics collection and monitoring
+4. Test with multiple broker instances
+5. Implement schema evolution testing

+# SeaweedFS S3 Copying Tests
+
+This directory contains comprehensive Go tests for SeaweedFS S3 copying functionality, converted from the failing Python tests in the s3-tests repository.
+
+## Overview
+
+These tests verify that SeaweedFS correctly implements S3 operations, starting with basic put/get operations and progressing to advanced copy operations, including:
+- **Basic S3 Operations**: Put/Get operations, bucket management, and metadata handling
+- **Basic object copying**: within the same bucket
+- **Cross-bucket copying**: across different buckets
+- **Multipart copy operations**: for large files
+- **Conditional copy operations**: ETag-based conditional copying
+- **Metadata handling**: during copy operations
+- **ACL handling**: during copy operations
+
+## Test Coverage
+
+### Basic S3 Operations (Run First)
+- **TestBasicPutGet**: Tests fundamental S3 put/get operations with various object types

+- **TestCopyObjectIfNoneMatchGood**: Tests copying with matching ETag condition (should fail)
+
+## Requirements
+
+1. **Go 1.19+**: Required for AWS SDK v2 and modern Go features
+2. **SeaweedFS Binary**: Built from source (`../../../weed/weed`)
+3. **Free Ports**: 8333 (S3), 8888 (Filer), 8080 (Volume), 9333 (Master)
+4. **Dependencies**: Uses the main repository's go.mod with existing AWS SDK v2 and testify dependencies
+
+## Quick Start

+
+```json
+{
+  "endpoint": "http://localhost:8333",
+  "access_key": "some_access_key1",
+  "secret_key": "some_secret_key1",
+  "region": "us-east-1",
+  "bucket_prefix": "test-copying-",
+  "use_ssl": false,
+  "skip_verify_ssl": true
+}
+```
+
+You can modify these values in `test_config.json` or by setting environment variables:
+
+```bash
+export SEAWEEDFS_BINARY=/path/to/weed
+export S3_PORT=8333
+export FILER_PORT=8888
+export VOLUME_PORT=8080
+export MASTER_PORT=9333
+export TEST_TIMEOUT=10m
+export VOLUME_MAX_SIZE_MB=50
+```
+
+**Note**: The volume size limit is set to 50MB to ensure proper testing of volume boundaries and multipart operations.

+## Expected Behavior
+
+These tests verify that SeaweedFS correctly implements:
+
+1. **Basic S3 Operations**: Standard `PutObject`, `GetObject`, `ListBuckets`, `ListObjects` APIs
+2. **Bucket Management**: Bucket creation, deletion, and listing
+3. **Object Storage**: Binary and text data storage with metadata
+4. **Large Object Handling**: Efficient storage and retrieval of large files
+5. **Basic S3 Copy Operations**: Standard `CopyObject` API
+6. **Multipart Copy Operations**: `UploadPartCopy` API with range support
+7. **Conditional Operations**: ETag-based conditional copying
+8. **Metadata Handling**: Proper metadata preservation and replacement
+9. **ACL Handling**: Access control list management during copy
+10. **Error Handling**: Proper error responses for invalid operations
+
+## Troubleshooting
+
+### Common Issues
+
+1. **Port Already in Use**
+   ```bash
+   make stop-seaweedfs
+   make clean
+   ```
+
+2. **SeaweedFS Binary Not Found**
+   ```bash
+   cd ../../../
+   make
+   ```
+
+3. **Test Timeouts**
+   ```bash
+   export TEST_TIMEOUT=30m
+   make test
+   ```
+
+4. **Permission Denied**
+   ```bash
+   sudo make clean
+   ```
+
+### Debug Information
+
+```bash
+# Check server status
+make debug-status
+
+# View recent logs
+make debug-logs
+
+# Manual server start for investigation
+make manual-start
+# ... perform manual testing ...
+make manual-stop
+```
+
+### Log Locations
+
+When running tests, logs are stored in:
+- Master: `/tmp/seaweedfs-master.log`
+- Volume: `/tmp/seaweedfs-volume.log`
+- Filer: `/tmp/seaweedfs-filer.log`
+- S3: `/tmp/seaweedfs-s3.log`
+
+## Contributing
+
+When adding new tests:
+
+1. Follow the existing naming convention (`TestXxxYyy`)
+2. Use the helper functions for common operations
+3. Add cleanup with `defer deleteBucket(t, client, bucketName)`
+4. Include error checking with `require.NoError(t, err)`
+5. Use assertions with `assert.Equal(t, expected, actual)`
+6. Add the test to the appropriate Make target
+
+## Performance Notes
+
+- **TestMultipartCopyMultipleSizes** is the most resource-intensive test
+- Large file tests may take several minutes to complete
+- Memory usage scales with file sizes being tested
+- Network latency affects multipart copy performance
+
+## Integration with CI/CD
+
+For automated testing:
+
+```bash
+# Basic validation (recommended first)
+make test-basic
+
+# Quick validation
+make ci-test
+
+# Full validation
+make test-full
+
+# Performance validation
+make perf
+```
+
+The tests are designed to be self-contained and can run in containerized environments.

+# CORS Integration Tests for SeaweedFS S3 API
+
+This directory contains comprehensive integration tests for the CORS (Cross-Origin Resource Sharing) functionality in SeaweedFS S3 API.
+
+## Overview
+
+The CORS integration tests validate the complete CORS implementation including:
+- CORS configuration management (PUT/GET/DELETE)
+- CORS rule validation
+- CORS middleware behavior
+- Caching functionality
+- Error handling
+- Real-world CORS scenarios
+
+## Prerequisites
+
+1. **Go 1.19+**: For building SeaweedFS and running tests
+2. **Network Access**: Tests use `localhost:8333` by default
+3. **System Dependencies**: `curl` and `netstat` for health checks
+
+## Quick Start
+
+The tests now automatically start their own SeaweedFS server, so you don't need to manually start one.
+
+### 1. Run All Tests with Managed Server
+
+```bash
+# Run all tests with automatic server management
+make test-with-server
+
+# Run core CORS tests only
+make test-cors-quick
+
+# Run comprehensive CORS tests
+make test-cors-comprehensive
+```
+
+### 2. Manual Server Management
+
+If you prefer to manage the server manually:
+
+```bash
+# Start server
+make start-server
+
+# Run tests (assuming server is running)
+make test-cors-simple
+
+# Stop server
+make stop-server
+```
+
+### 3. Individual Test Categories
+
+```bash
+# Run specific test types
+make test-basic-cors           # Basic CORS configuration
+make test-preflight-cors       # Preflight OPTIONS requests
+make test-actual-cors          # Actual CORS request handling
+make test-origin-matching      # Origin matching logic
+make test-header-matching      # Header matching logic
+make test-method-matching      # Method matching logic
+make test-multiple-rules       # Multiple CORS rules
+make test-validation           # CORS validation
+make test-caching              # CORS caching behavior
+make test-error-handling       # Error handling
+```
+
+## Test Server Management
+
+The tests use a comprehensive server management system similar to other SeaweedFS integration tests:
+
+### Server Configuration
+
+- **S3 Port**: 8333 (configurable via `S3_PORT`)
+- **Master Port**: 9333
+- **Volume Port**: 8080
+- **Filer Port**: 8888
+- **Metrics Port**: 9324
+- **Data Directory**: `./test-volume-data` (auto-created)
+- **Log File**: `weed-test.log`
+
+### Server Lifecycle
+
+1. **Build**: Automatically builds `../../../weed/weed_binary`
+2. **Start**: Launches SeaweedFS with S3 API enabled
+3. **Health Check**: Waits up to 90 seconds for server to be ready
+4. **Test**: Runs the requested tests
+5. **Stop**: Gracefully shuts down the server
+6. **Cleanup**: Removes temporary files and data
+
+### Available Commands
+
+```bash
+# Server management
+make start-server              # Start SeaweedFS server
+make stop-server               # Stop SeaweedFS server
+make health-check              # Check server health
+make logs                      # View server logs
+
+# Test execution
+make test-with-server          # Full test cycle with server management
+make test-cors-simple          # Run tests without server management
+make test-cors-quick           # Run core tests only
+make test-cors-comprehensive   # Run all tests
+
+# Development
+make dev-start                 # Start server for development
+make dev-test                  # Run development tests
+make build-weed                # Build SeaweedFS binary
+make check-deps                # Check dependencies
+
+# Maintenance
+make clean                     # Clean up all artifacts
+make coverage                  # Generate coverage report
+make fmt                       # Format code
+make lint                      # Run linter
+```
+
+## Test Configuration
+
+### Default Configuration
+
+The tests use these default settings (configurable via environment variables):
+
+```bash
+WEED_BINARY=../../../weed/weed_binary
+S3_PORT=8333
+TEST_TIMEOUT=10m
+TEST_PATTERN=TestCORS
+```
+
+### Configuration File
+
+The `test_config.json` file contains S3 client configuration:
+
+```json
+{
+  "endpoint": "http://localhost:8333",
+  "access_key": "some_access_key1",
+  "secret_key": "some_secret_key1",
+  "region": "us-east-1",
+  "bucket_prefix": "test-cors-",
+  "use_ssl": false,
+  "skip_verify_ssl": true
+}
+```
+
+## Troubleshooting
+
+### Compilation Issues
+
+If you encounter compilation errors, the most common issues are:
+
+1. **AWS SDK v2 Type Mismatches**: The `MaxAgeSeconds` field in `types.CORSRule` expects `int32`, not `*int32`. Use direct values like `3600` instead of `aws.Int32(3600)`.
+
+2. **Field Name Issues**: The `GetBucketCorsOutput` type has a `CORSRules` field directly, not a `CORSConfiguration` field.
+
+Example fix:
+```go
+// ❌ Incorrect
+MaxAgeSeconds: aws.Int32(3600),
+assert.Len(t, getResp.CORSConfiguration.CORSRules, 1)
+
+// ✅ Correct
+MaxAgeSeconds: 3600,
+assert.Len(t, getResp.CORSRules, 1)
+```
+
+### Server Issues
+
+1. **Server Won't Start**
+   ```bash
+   # Check for port conflicts
+   netstat -tlnp | grep 8333
+   
+   # View server logs
+   make logs
+   
+   # Force cleanup
+   make clean
+   ```
+
+2. **Test Failures**
+   ```bash
+   # Run with server management
+   make test-with-server
+   
+   # Run specific test
+   make test-basic-cors
+   
+   # Check server health
+   make health-check
+   ```
+
+3. **Connection Issues**
+   ```bash
+   # Verify server is running
+   curl -s http://localhost:8333
+   
+   # Check server logs
+   tail -f weed-test.log
+   ```
+
+### Performance Issues
+
+If tests are slow or timing out:
+
+```bash
+# Increase timeout
+export TEST_TIMEOUT=30m
+make test-with-server
+
+# Run quick tests only
+make test-cors-quick
+
+# Check server resources
+make debug-status
+```

+#### 3. Without Configuration (`TestCORSWithoutConfiguration`)
+- Behavior when no CORS configuration exists
+- Default CORS behavior
+- Graceful degradation
+
+## Development
+
+### Running Tests During Development
+
+```bash
+# Start server for development
+make dev-start
+
+# Run quick test
+make dev-test
+
+# View logs in real-time
+make logs
+```
+
+### Adding New Tests
+
+1. Follow the existing naming convention (`TestCORSXxxYyy`)
+2. Use the helper functions (`getS3Client`, `createTestBucket`, etc.)
+3. Add cleanup with `defer cleanupTestBucket(t, client, bucketName)`
+4. Include proper error checking with `require.NoError(t, err)`
+5. Use assertions with `assert.Equal(t, expected, actual)`
+6. Add the test to the appropriate Makefile target
+
+### Code Quality
+
+```bash
+# Format code
+make fmt
+
+# Run linter
+make lint
+
+# Generate coverage report
+make coverage
+```
+
+## Performance Notes
+
+- Tests create and destroy buckets for each test case
+- Large configuration tests may take several minutes
+- Server startup typically takes 15-30 seconds
+- Tests run in parallel where possible for efficiency
+
+## Integration with SeaweedFS
+
+These tests validate the CORS implementation in:
+- `weed/s3api/cors/` - Core CORS package
+- `weed/s3api/s3api_bucket_cors_handlers.go` - HTTP handlers
+- `weed/s3api/s3api_server.go` - Router integration
+- `weed/s3api/s3api_bucket_config.go` - Configuration management
+
+The tests ensure AWS S3 API compatibility and proper CORS behavior across all supported scenarios.

+# SeaweedFS S3 Object Retention Tests
+
+This directory contains comprehensive tests for SeaweedFS S3 Object Retention functionality, including Object Lock, Legal Hold, and WORM (Write Once Read Many) capabilities.
+
+## Overview
+
+The test suite validates AWS S3-compatible object retention features including:
+
+- **Object Retention**: GOVERNANCE and COMPLIANCE modes with retain-until-date
+- **Legal Hold**: Independent protection that can be applied/removed
+- **Object Lock Configuration**: Bucket-level default retention policies  
+- **WORM Integration**: Compatibility with legacy WORM functionality
+- **Version-specific Retention**: Different retention policies per object version
+- **Enforcement**: Protection against deletion and overwriting
+
+## Test Files
+
+- `s3_retention_test.go` - Core retention functionality tests
+- `s3_worm_integration_test.go` - WORM integration and advanced scenarios
+- `test_config.json` - Test configuration (endpoints, credentials)
+- `Makefile` - Comprehensive test automation
+- `go.mod` - Go module dependencies
+
+## Prerequisites
+
+- Go 1.21 or later
+- SeaweedFS binary built (`make build-weed`)
+- AWS SDK Go v2
+- Testify testing framework
+
+## Quick Start
+
+### 1. Build and Start Server
+```bash
+# Build SeaweedFS and start test server
+make start-server
+```
+
+### 2. Run Tests
+```bash
+# Run core retention tests
+make test-retention-quick
+
+# Run all retention tests
+make test-retention
+
+# Run WORM integration tests  
+make test-retention-worm
+
+# Run all tests with managed server
+make test-with-server
+```
+
+### 3. Cleanup
+```bash
+make clean
+```
+
+## Test Categories
+
+### Core Retention Tests
+- `TestBasicRetentionWorkflow` - Basic GOVERNANCE mode retention
+- `TestRetentionModeCompliance` - COMPLIANCE mode (immutable)
+- `TestLegalHoldWorkflow` - Legal hold on/off functionality
+- `TestObjectLockConfiguration` - Bucket object lock settings
+
+### Advanced Tests
+- `TestRetentionWithVersions` - Version-specific retention policies
+- `TestRetentionAndLegalHoldCombination` - Multiple protection types
+- `TestExpiredRetention` - Post-expiration behavior
+- `TestRetentionErrorCases` - Error handling and edge cases
+
+### WORM Integration Tests
+- `TestWORMRetentionIntegration` - New retention + legacy WORM
+- `TestWORMLegacyCompatibility` - Backward compatibility
+- `TestRetentionOverwriteProtection` - Prevent overwrites
+- `TestRetentionBulkOperations` - Bulk delete with retention
+- `TestRetentionWithMultipartUpload` - Multipart upload retention
+- `TestRetentionExtendedAttributes` - Extended attribute storage
+- `TestRetentionBucketDefaults` - Default retention application
+- `TestRetentionConcurrentOperations` - Concurrent operation safety
+
+## Individual Test Targets
+
+Run specific test categories:
+
+```bash
+# Basic functionality
+make test-basic-retention
+make test-compliance-retention  
+make test-legal-hold
+
+# Advanced features
+make test-retention-versions
+make test-retention-combination
+make test-expired-retention
+
+# WORM integration
+make test-worm-integration
+make test-worm-legacy
+make test-retention-bulk
+```
+
+## Configuration
+
+### Server Configuration
+The tests use these default settings:
+- S3 Port: 8333
+- Test timeout: 15 minutes
+- Volume directory: `./test-volume-data`
+
+### Test Configuration (`test_config.json`)
+```json
+{
+  "endpoint": "http://localhost:8333",
+  "access_key": "some_access_key1", 
+  "secret_key": "some_secret_key1",
+  "region": "us-east-1",
+  "bucket_prefix": "test-retention-",
+  "use_ssl": false,
+  "skip_verify_ssl": true
+}
+```
+
+## Expected Behavior
+
+### GOVERNANCE Mode
+- Objects protected until retain-until-date
+- Can be bypassed with `x-amz-bypass-governance-retention` header
+- Supports time extension (not reduction)
+
+### COMPLIANCE Mode  
+- Objects immutably protected until retain-until-date
+- Cannot be bypassed or shortened
+- Strictest protection level
+
+### Legal Hold
+- Independent ON/OFF protection
+- Can coexist with retention policies
+- Must be explicitly removed to allow deletion
+
+### Version Support
+- Each object version can have individual retention
+- Applies to both versioned and non-versioned buckets
+- Version-specific retention retrieval
+
+## Development
+
+### Running in Development Mode
+```bash
+# Start server for development
+make dev-start
+
+# Run quick test
+make dev-test
+```
+
+### Code Quality
+```bash
+# Format code
+make fmt
+
+# Run linter
+make lint
+
+# Generate coverage report
+make coverage
+```
+
+### Performance Testing
+```bash
+# Run benchmarks
+make benchmark-retention
+```
+
+## Troubleshooting
+
+### Server Won't Start
+```bash
+# Check if port is in use
+netstat -tlnp | grep 8333
+
+# View server logs
+make logs
+
+# Force cleanup
+make clean
+```
+
+### Test Failures
+```bash
+# Run with verbose output
+go test -v -timeout=15m .
+
+# Run specific test
+go test -v -run TestBasicRetentionWorkflow .
+
+# Check server health
+make health-check
+```
+
+### Dependencies
+```bash
+# Install/update dependencies
+make install-deps
+
+# Check dependency status
+make check-deps
+```
+
+## Integration with SeaweedFS
+
+These tests validate the retention implementation in:
+- `weed/s3api/s3api_object_retention.go` - Core retention logic
+- `weed/s3api/s3api_object_handlers_retention.go` - HTTP handlers
+- `weed/s3api/s3_constants/extend_key.go` - Extended attribute keys
+- `weed/s3api/s3err/s3api_errors.go` - Error definitions
+- `weed/s3api/s3api_object_handlers_delete.go` - Deletion enforcement
+- `weed/s3api/s3api_object_handlers_put.go` - Upload enforcement
+
+## AWS CLI Compatibility
+
+The retention implementation supports standard AWS CLI commands:
+
+```bash
+# Set object retention
+aws s3api put-object-retention \
+  --bucket mybucket \
+  --key myobject \
+  --retention Mode=GOVERNANCE,RetainUntilDate=2024-12-31T23:59:59Z
+
+# Get object retention
+aws s3api get-object-retention \
+  --bucket mybucket \
+  --key myobject
+
+# Set legal hold
+aws s3api put-object-legal-hold \
+  --bucket mybucket \
+  --key myobject \
+  --legal-hold Status=ON
+
+# Configure bucket object lock
+aws s3api put-object-lock-configuration \
+  --bucket mybucket \
+  --object-lock-configuration ObjectLockEnabled=Enabled,Rule='{DefaultRetention={Mode=GOVERNANCE,Days=30}}'
+```
+
+## Contributing
+
+When adding new retention tests:
+
+1. Follow existing test patterns
+2. Use descriptive test names
+3. Include both positive and negative test cases
+4. Test error conditions
+5. Update this README with new test descriptions
+6. Add appropriate Makefile targets for new test categories

+# SeaweedFS Admin Component
+
+A modern web-based administration interface for SeaweedFS clusters built with Go, Gin, Templ, and Bootstrap.
+
+## Features
+
+- **Dashboard**: Real-time cluster status and metrics
+- **Master Management**: Monitor master nodes and leadership status
+- **Volume Server Management**: View volume servers, capacity, and health
+- **Object Store Bucket Management**: Create, delete, and manage Object Store buckets with web interface
+- **System Health**: Overall cluster health monitoring
+- **Responsive Design**: Bootstrap-based UI that works on all devices
+- **Authentication**: Optional user authentication with sessions
+- **TLS Support**: HTTPS support for production deployments
+
+## Building
+
+### Using the Admin Makefile
+
+The admin component has its own Makefile for development and building:
+
+```bash
+# Navigate to admin directory
+cd weed/admin
+
+# View all available targets
+make help
+
+# Generate templates and build
+make build
+
+# Development mode with template watching
+make dev
+
+# Run the admin server
+make run
+
+# Clean build artifacts
+make clean
+```
+
+### Using the Root Makefile
+
+The root SeaweedFS Makefile automatically integrates the admin component:
+
+```bash
+# From the root directory
+make install          # Builds weed with admin component
+make full_install     # Full build with all tags
+make test            # Runs tests including admin component
+
+# Admin-specific targets from root
+make admin-generate  # Generate admin templates
+make admin-build     # Build admin component
+make admin-run       # Run admin server
+make admin-dev       # Development mode
+make admin-clean     # Clean admin artifacts
+```
+
+### Manual Building
+
+If you prefer to build manually:
+
+```bash
+# Install templ compiler
+go install github.com/a-h/templ/cmd/templ@latest
+
+# Generate templates
+templ generate
+
+# Build the main weed binary
+cd ../../../
+go build -o weed ./weed
+```
+
+## Development
+
+### Template Development
+
+The admin interface uses [Templ](https://templ.guide/) for type-safe HTML templates:
+
+```bash
+# Watch for template changes and auto-regenerate
+make watch
+
+# Or manually generate templates
+make generate
+
+# Format templates
+make fmt
+```
+

+```
+
+### S3 Bucket Management
+
+The admin interface includes comprehensive Object Store bucket management capabilities. See [S3_BUCKETS.md](S3_BUCKETS.md) for detailed documentation on:
+
+- Creating and deleting Object Store buckets
+- Viewing bucket contents and metadata
+- Managing bucket permissions and settings
+- API endpoints for programmatic access
+
+## Usage
+
+### Basic Usage
+
+```bash
+# Start admin interface on default port (23646)
+weed admin
+
+# Start with custom configuration
+weed admin -port=8080 -masters="master1:9333,master2:9333"
+
+# Start with authentication
+weed admin -adminUser=admin -adminPassword=secret123
+
+# Start with HTTPS
+weed admin -port=443 -tlsCert=/path/to/cert.pem -tlsKey=/path/to/key.pem
+```
+
+### Configuration Options
+
+| Option | Default | Description |
+|--------|---------|-------------|
+| `-port` | 23646 | Admin server port |
+| `-masters` | localhost:9333 | Comma-separated master servers |
+| `-adminUser` | admin | Admin username (if auth enabled) |
+| `-adminPassword` | "" | Admin password (empty = no auth) |
+| `-tlsCert` | "" | Path to TLS certificate |
+| `-tlsKey` | "" | Path to TLS private key |
+
+### Docker Usage
+
+```bash
+# Build Docker image with admin component
+make docker-build
+
+# Run with Docker
+docker run -p 23646:23646 seaweedfs/seaweedfs:latest admin -masters=host.docker.internal:9333
+```
+
+## Development Workflow
+
+### Quick Start
+
+```bash
+# Clone and setup
+git clone <seaweedfs-repo>
+cd seaweedfs/weed/admin
+
+# Install dependencies and build
+make install-deps
+make build
+
+# Start development server
+make dev
+```
+
+### Making Changes
+
+1. **Template Changes**: Edit `.templ` files in `view/`
+   - Templates auto-regenerate in development mode
+   - Use `make generate` to manually regenerate
+
+2. **Go Code Changes**: Edit `.go` files
+   - Restart the server to see changes
+   - Use `make build` to rebuild
+
+3. **Static Assets**: Edit files in `static/`
+   - Changes are served immediately
+
+### Testing
+
+```bash
+# Run admin component tests
+make test
+
+# Run from root directory
+make admin-test
+
+# Lint code
+make lint
+
+# Format code
+make fmt
+```
+
+## Production Deployment
+
+### Security Considerations
+
+1. **Authentication**: Always set `adminPassword` in production
+2. **HTTPS**: Use TLS certificates for encrypted connections
+3. **Firewall**: Restrict admin interface access to authorized networks
+
+### Example Production Setup
+
+```bash
+# Production deployment with security
+weed admin \
+  -port=443 \
+  -masters="master1:9333,master2:9333,master3:9333" \
+  -adminUser=admin \
+  -adminPassword=your-secure-password \
+  -tlsCert=/etc/ssl/certs/admin.crt \
+  -tlsKey=/etc/ssl/private/admin.key
+```
+
+### Monitoring
+
+The admin interface provides endpoints for monitoring:
+
+- `GET /health` - Health check endpoint
+- `GET /metrics` - Prometheus metrics (if enabled)
+- `GET /api/status` - JSON status information
+
+## Troubleshooting
+
+### Common Issues
+
+1. **Templates not found**: Run `make generate` to create template files
+2. **Build errors**: Ensure `templ` is installed with `make install-templ`
+3. **Static files not loading**: Check that `static/` directory exists and has proper files
+4. **Connection errors**: Verify master and filer addresses are correct
+
+### Debug Mode
+
+```bash
+# Enable debug logging
+weed -v=2 admin
+
+# Check generated templates
+ls -la view/app/*_templ.go view/layout/*_templ.go
+```
+
+## Contributing
+
+1. Fork the repository
+2. Create a feature branch
+3. Make your changes
+4. Run tests: `make test`
+5. Format code: `make fmt`
+6. Submit a pull request
+
+## Architecture
+
+The admin component follows a clean architecture:
+
+- **Presentation Layer**: Templ templates + Bootstrap CSS
+- **HTTP Layer**: Gin router with middleware
+- **Business Logic**: Handler functions in `dash/` package
+- **Data Layer**: Communicates with SeaweedFS masters and filers
+
+This separation makes the code maintainable and testable.
