Maintenance & Dependency Release

The library API is unchanged from v0.3.2 — src/fastapi_testing is byte-identical. This release modernizes dependencies (security fixes + latest compatible versions) and CI tooling.

Dependencies

• Security updates: starlette, pygments, and pytest moved to patched releases.
• Minimums raised to the latest releases that still support Python ≥ 3.11:
  • Runtime: fastapi>=0.137.2, starlette>=1.3.1, uvicorn>=0.49.0, websockets>=16.0
  • Dev/build: pytest>=9.1.0, pytest-asyncio>=1.4.0, pytest-cov>=7.1.0, pydantic>=2.13.4, ruff>=0.15.17, hatchling>=1.30.1

Note for consumers: installing fastapi-testing 0.3.3 now pulls in the newer FastAPI / Starlette / Uvicorn minimums listed above.

CI / Tooling

• GitHub Actions upgraded to current majors: checkout v7, setup-python v6, setup-uv v8.2.0, codecov-action v7, attest-build-provenance v4.
• Fixed the pinned uv version in CI (0.5.11 → 0.11.13) so it can parse the current revision = 3 lockfile.
• "Build and Test" now runs on pull requests.

Compatibility

• Python 3.11–3.13. No public API changes; no migration required.

🎯 Simplified pgvector Support

This release simplifies pgvector integration by removing the pgvector-python library dependency and using native JSON parsing instead. This results in zero external dependencies, better Pydantic compatibility, and simpler code.

✨ What's Changed

Removed Dependencies

• Removed pgvector-python dependency - No longer required for vector support
• Removed numpy dependency - Vector data returned as native Python list[float]

Simplified Implementation

• PostgreSQL returns vectors as strings like '[0.1,0.2,0.3]'
• Automatically parsed to list[float] using built-in JSON parsing
• Removed 28 lines of adapter registration complexity
• No async adapter registration needed

Performance

• Negligible overhead: <0.1ms per vector for JSON parsing
• For 1000 vectors: ~10-100ms difference vs adapter (1-10% overhead)
• Completely acceptable for typical LLM embedding use cases

🚀 Key Benefits

✅ Zero External Dependencies - No pgvector-python, no numpy required ✅ Simpler Code - Removed async adapter registration logic ✅ Perfect Pydantic Compatibility - Returns list[float], not numpy.ndarray ✅ No Breaking Changes - Same public API, drop-in upgrade ✅ All Tests Passing - 227 tests with zero regressions

📦 Installation

pip install psycopg-toolkit==0.3.1

💻 Usage Example

from pydantic import BaseModel
from psycopg_toolkit import BaseRepository
from uuid import UUID

class DocumentEmbedding(BaseModel):
    id: UUID
    document_id: UUID
    embedding: list[float]  # Auto-detected as vector field
    metadata: dict[str, Any] | None = None

class EmbeddingRepository(BaseRepository[DocumentEmbedding, UUID]):
    def __init__(self, db_connection):
        super().__init__(
            db_connection=db_connection,
            table_name="embeddings",
            model_class=DocumentEmbedding,
            primary_key="id",
            auto_detect_vector=True,  # Automatically detects list[float]
        )

# Usage - works seamlessly with PostgreSQL pgvector extension
embedding_vector = [0.1] * 384  # 384-dimensional vector
doc = DocumentEmbedding(
    id=uuid4(),
    document_id=uuid4(),
    embedding=embedding_vector,
    metadata={"model": "all-MiniLM-L6-v2"}
)

created = await repo.create(doc)
assert isinstance(created.embedding, list)  # Returns list[float]!

🔧 Technical Details

Before (v0.3.0):

• Required pgvector-python>=0.4.1 dependency
• Used register_vector_async() adapter registration
• Returned vectors as numpy.ndarray
• Required numpy as transitive dependency

After (v0.3.1):

• No external dependencies needed
• Simple JSON parsing with JSONHandler.deserialize()
• Returns vectors as native Python list[float]
• Direct Pydantic compatibility

Release Notes v0.4.4

🚀 New Features

Cache Metadata Tracking

• Added from_cache metadata field to all task responses and status objects
• Tasks now indicate whether their results were served from cache (true) or freshly computed (false)
• Available in all API endpoints: /api/v1/tasks, /api/v1/tasks/{task_id}, and task listings

Enhanced Completion Callbacks

• Updated completion callback signature to include cache metadata: (task_id, result, from_cache)
• Backward compatibility maintained - existing callbacks without the from_cache parameter continue to work
• Cache hits and fresh computations are now distinguishable in callback handlers

🔧 Improvements

API Enhancements

• All task response models now include the from_cache boolean field
• Task serialization (.to_dict()) includes cache metadata
• Consistent cache metadata across all task management operations

Testing

• Added comprehensive test coverage for cache metadata functionality
• Tests verify cache metadata in both direct task execution and API responses
• Ensures cache metadata is properly serialized and deserialized

📦 Dependencies

• Updated redis: 6.1.0 → 6.2.0

🔄 Breaking Changes

None - This release maintains full backward compatibility with existing code.

💡 Usage Examples

Checking if a result came from cache:

task_info = await worker.get_task_info(task_id)
if task_info.from_cache:
    print("Result was served from cache")
else:
    print("Result was freshly computed")

Using the enhanced completion callback:

async def on_task_complete(task_id: str, result: Any, from_cache: bool):
    if from_cache:
        logger.info(f"Cache hit for task {task_id}")
    else:
        logger.info(f"Fresh computation for task {task_id}")

# Old callbacks still work:
async def legacy_callback(task_id: str, result: Any):
    logger.info(f"Task {task_id} completed")

API Response Example:

{
  "id": "task-123",
  "status": "completed",
  "result": {"value": "computed_result"},
  "from_cache": true,
  "progress": 1.0,
  "metadata": {}
}

This release enhances observability and debugging capabilities while maintaining full backward compatibility with existing applications.
