The identified issues—such as the synchronous I/O blocks in `src/proxy_app/main.py` lifespan and `src/rotator_library/usage/persistence/storage.py`, the `HTTPException` swallowing in `/v1/token-count`, the O(N) cache miss amplification in `ProviderCache`, and the embedding batch usage overcounting—are all verified present in the codebase. The phased rollout strategy (M1-M7) and feature flag recommendations provide a safe path for implementation without risking endpoint regressions. + +## Critical Issues +*None found in the plan itself.* The plan correctly identifies critical issues in the codebase and proposes sound solutions. + +## Important Issues +- **`asyncio.to_thread` usage (C1):** In `src/rotator_library/utils/resilient_io.py`, the `_writer.write()` method uses a synchronous `flock` and standard `open()`. When migrating the `save()` method in `storage.py` off the event loop, simply wrapping `self._writer.write(data)` in `asyncio.to_thread()` is the safest approach without needing to rewrite the resilient disk I/O library to be natively async. The plan mentions this, but it's worth emphasizing to prevent scope creep. + +## Suggestions +- **FastAPI CORS default migration (D2):** When shifting from `allow_origins=["*"]` to an explicit allowlist in `src/proxy_app/main.py`, ensure that `http://localhost:*` and `http://127.0.0.1:*` are included in the default fallback if the environment variable is not explicitly set. This prevents breaking local UI/TUI developer workflows out of the box. +- **Dependency Separation (F3):** When splitting `requirements.txt` into runtime and dev dependencies, be careful not to remove `rich` or `prompt_toolkit` from runtime if they are used by the CLI/TUI entry points (which they appear to be in `main.py` onboarding). + +## Codebase Alignment +- **A1 (`/v1/token-count` fix):** -> Aligns perfectly with `src/proxy_app/main.py:1497-1520` (exception block catches `HTTPException` and re-raises as 500). +- **A2 (Embedding usage):** -> Aligns perfectly with `src/proxy_app/batch_manager.py` (usage object is attached to every single batch item unconditionally). +- **B1 (Streaming wrapper):** -> Aligns perfectly with `src/proxy_app/main.py:717` (`streaming_response_wrapper` builds `response_chunks` regardless of logging mode). +- **B3 (ProviderCache amplification):** -> Aligns perfectly with `src/rotator_library/providers/provider_cache.py:382` (spawns un-deduplicated `_check_disk_fallback` tasks on every miss). +- **C1 (Async I/O):** -> Aligns perfectly with `main.py`'s `lifespan` function (sync `json.load`) and `storage.py`'s `save` function (sync `write()`). +- **D1/D2 (Security defaults):** -> Aligns perfectly; API key is printed plaintext at `main.py:96`, and CORS uses `["*"]` with `allow_credentials=True` at `main.py:666`. + +## Approval Status +**READY TO IMPLEMENT** diff --git a/src/proxy_app/app_factory.py b/src/proxy_app/app_factory.py new file mode 100644 index 00000000..bc358eae --- /dev/null +++ b/src/proxy_app/app_factory.py @@ -0,0 +1,88 @@ +# SPDX-License-Identifier: MIT +# Copyright (c) 2026 Mirrowel + +""" +FastAPI application factory. + +This module provides the create_app() function for creating and configuring +the FastAPI application instance. +""" + +import logging +import os +from pathlib import Path +from typing import Optional + +from fastapi import FastAPI +from fastapi.middleware.cors import CORSMiddleware + +from proxy_app.startup import lifespan + + +def create_app(data_dir: Optional[Path] = None) -> FastAPI: + """ + Create and configure the FastAPI application. + + Args: + data_dir: Optional data directory path + + Returns: + Configured FastAPI application instance + """ + # Create app with lifespan + app = FastAPI( + title="LLM API Key Proxy", + description="A proxy server for LLM API key rotation and management", + version="1.0.0", + lifespan=lambda app: lifespan(app, data_dir), + ) + + # Configure CORS + _configure_cors(app) + + # Register routes + _register_routes(app) + + return app + + +def _configure_cors(app: FastAPI) -> None: + """Configure CORS middleware from environment variables.""" + # PROXY_CORS_ORIGINS: comma-separated list or "*" for all + _cors_origins_env = os.getenv("PROXY_CORS_ORIGINS", "*") + _cors_origins = [origin.strip() for origin in _cors_origins_env.split(",") if origin.strip()] + _cors_credentials = os.getenv("PROXY_CORS_CREDENTIALS", "false").lower() == "true" + + # Security warnings + if _cors_origins == ["*"]: + logging.warning( + "CORS is configured to allow all origins (*).
