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

# Build SeaweedFS and start test server
make start-server

2. Run Tests

# 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

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:

# 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)

{
  "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

# Start server for development
make dev-start

# Run quick test
make dev-test

Code Quality

# Format code
make fmt

# Run linter
make lint

# Generate coverage report
make coverage

Performance Testing

# Run benchmarks
make benchmark-retention

Troubleshooting

Server Won't Start

# Check if port is in use
netstat -tlnp | grep 8333

# View server logs
make logs

# Force cleanup
make clean

Test Failures

# Run with verbose output
go test -v -timeout=15m .

# Run specific test
go test -v -run TestBasicRetentionWorkflow .

# Check server health
make health-check

Dependencies

# 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:

# 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
