feat: Add bucket management APIs and improve SDK filtering

Browse Source 
This commit adds core bucket management functionality and enhances the SDK's internal file filtering to provide a cleaner abstraction layer.

**Bucket Management**:
- Add create_bucket(), delete_bucket(), list_buckets() to DeltaGliderClient
- Idempotent operations (creating existing bucket or deleting non-existent returns success)
- Complete boto3-compatible API for basic bucket operations
- Eliminates need for boto3 in most use cases

**Enhanced SDK Filtering**:
- SDK now filters .delta suffix and reference.bin from all list_objects() responses
- Simplified CLI to rely on SDK filtering (removed duplicate logic)
- Single source of truth for internal file hiding

**Delete Cleanup Logic**:
- Automatically removes orphaned reference.bin when last delta in DeltaSpace is deleted
- Prevents storage waste from abandoned reference files
- Works for both single delete() and recursive delete_recursive()

**Documentation & Testing**:
- Added BOTO3_COMPATIBILITY.md documenting actual 20% method coverage (21/100+ methods)
- Updated README to reflect accurate boto3 compatibility claims
- New comprehensive test suite for filtering and cleanup features (test_filtering_and_cleanup.py)
- New bucket management test suite (test_bucket_management.py)
- Example code for bucket lifecycle management (examples/bucket_management.py)
- Fixed mypy configuration to eliminate source file found twice errors
- All CI checks passing (lint, format, type check, 18 unit tests, 61 integration tests)

**Cleanup**:
- Removed PYPI_RELEASE.md (redundant with existing docs)

## Coverage Analysis
**Implemented:** ~21 methods
**Total boto3 S3 methods:** ~100+ methods
**Coverage:** ~20%
## What's Covered
DeltaGlider focuses on:
1. ✅ **Core CRUD operations** - put, get, delete, list
2. ✅ **Bucket management** - create, delete, list buckets
3. ✅ **Basic metadata** - head_object
4. ✅ **Presigned URLs** - generate_presigned_url/post
5. ✅ **Delta compression** - automatic for archive files
6. ✅ **Batch operations** - upload_batch, download_batch
7. ✅ **Compression stats** - get_bucket_stats, estimate_compression
## What's NOT Covered
❌ **Advanced bucket configuration** (versioning, lifecycle, logging, etc.)
❌ **Access control** (ACLs, bucket policies)
❌ **Multipart uploads** (for >5GB files)
❌ **Advanced features** (S3 Select, Glacier, Object Lock)
❌ **Tagging APIs** (object/bucket tags)
❌ **High-level transfer utilities** (upload_file, download_file)
## Use Cases
### ✅ DeltaGlider is PERFECT for:
- Storing versioned releases/builds
- Backup storage with deduplication
- CI/CD artifact storage
- Docker layer storage
- Archive file storage (zip, tar, etc.)
- Simple S3 storage needs
### ❌ Use boto3 directly for:
- Complex bucket policies
- Versioning/lifecycle management
- Multipart uploads (>5GB files)
- S3 Select queries
- Glacier deep archive
- Object Lock/Legal Hold
- Advanced ACL management
## Migration Strategy
If you need both boto3 and DeltaGlider:
```python
from deltaglider import create_client
import boto3
# Use DeltaGlider for objects (with compression!)
dg_client = create_client()
dg_client.put_object(Bucket='releases', Key='app.zip', Body=data)
# Use boto3 for advanced features
s3_client = boto3.client('s3')
s3_client.put_bucket_versioning(
Bucket='releases',
VersioningConfiguration={'Status': 'Enabled'}
)
```
## Future Additions
Likely to be added:
- `upload_file()` / `download_file()` - High-level helpers
- `copy_object()` - Object copying
- Basic tagging support
- Multipart upload (for large files)
Unlikely to be added:
- Advanced bucket configuration
- ACL management
- S3 Select
- Glacier operations
## Conclusion
**DeltaGlider is NOT a 100% drop-in boto3 replacement.**
It implements the **20% of boto3 methods that cover 80% of use cases**, with a focus on:
- Core object operations
- Bucket management
- Delta compression for storage savings
- Simple, clean API
For advanced S3 features, use boto3 directly or in combination with DeltaGlider.

### Python SDK - Drop-in boto3 Replacement

#### Quick Start - boto3 Compatible API (Recommended)
DeltaGlider provides a **100% boto3-compatible API** that works as a drop-in replacement for AWS S3 SDK:
DeltaGlider provides a **boto3-compatible API** for core S3 operations (21 methods covering 80% of use cases):

@@ -239,8 +239,48 @@ stats = client.get_bucket_stats('releases', detailed_stats=True) # With compres
client.delete_object(Bucket='releases', Key='old-version.zip')
client.head_object(Bucket='releases', Key='v2.0.0/my-app.zip')
# Bucket management - no boto3 needed!
client.create_bucket(Bucket='my-new-bucket')
client.list_buckets()
client.delete_bucket(Bucket='my-new-bucket')
```
#### Bucket Management (NEW!)
**No boto3 required!** DeltaGlider now provides complete bucket management:
```python
from deltaglider import create_client
client = create_client()
# Create buckets
client.create_bucket(Bucket='my-releases')
# Create bucket in specific region (AWS only)
client.create_bucket(
Bucket='my-regional-bucket',
CreateBucketConfiguration={'LocationConstraint': 'us-west-2'}
)
# List all buckets
response = client.list_buckets()
for bucket in response['Buckets']:
print(f"{bucket['Name']} - {bucket['CreationDate']}")
# Delete bucket (must be empty)
client.delete_bucket(Bucket='my-old-bucket')
```
**Benefits:**
- ✅ No need to import boto3 separately for bucket operations
- ✅ Consistent API with DeltaGlider object operations
- ✅ Works with AWS S3, MinIO, and S3-compatible storage
- ✅ Idempotent operations (safe to retry)
See [examples/bucket_management.py](examples/bucket_management.py) for complete example.
#### Simple API (Alternative)
For simpler use cases, DeltaGlider also provides a streamlined API:
