Users faced several challenges: +1. **Manual Configuration**: To change API endpoints or timeouts, users often had to modify code directly or pass arguments to every function call. +2. **Lack of Environment Switching**: There was no standard way to switch between "development", "staging", and "production" environments locally or on servers. +3. **Inconsistent Configuration**: Different tools (CLI vs SDK) might resolve configuration differently or rely on scattered environment variables. +4. **No Persistence**: Setting a preference (like a preferred profile) wasn't persistent across sessions. + +## Thought Process + +To address these issues, we needed a system that is **deterministic**, **hierarchical**, and **user-friendly**. + +### Design Decisions: +1. **Singleton Pattern**: Since configuration is global to the process, a Singleton `ConfigManager` ensures that configuration is loaded once and accessible everywhere (`affine.config.config`). +2. **Hierarchical Configuration**: + * **Project Level** (`./affine.json`): Highest priority (except CLI flags). Allows per-project settings. + * **Global Level** (`~/.affine/config.json`): User-level defaults. + * This follows the standard precedence rule: CLI > Project > Global > Defaults. +3. **Profiles**: Instead of just flat keys, we group settings into "profiles". This allows a user to define a "local" profile pointing to `localhost:8000` and a "prod" profile pointing to the live API, and switch between them instantly. +4. **Schema Validation**: We used `pydantic` models (`ProfileConfig`) to enforce type safety. If a user provides a string for a timeout, the system fails fast with a clear error rather than causing cryptic runtime bugs. +5. **CLI & SDK Unification**: + * The CLI (`af`) was updated to expose configuration commands (`list`, `use`, `set`) and a global `--profile` flag. + * The SDK (`APIClient`) automatically reads from the active profile, so user code becomes cleaner (no more manually passing `base_url`). + +## The Fix + +### 1. New Configuration Module (`affine/config.py`) +We introduced `affine/config.py` which contains: +* `ProfileConfig`: Pydantic model for profile validation. +* `ConfigManager`: Singleton class that handles: + * Loading/merging JSON files. + * Managing the active profile state. + * Persisting changes (like `set_active_profile`). + +### 2. SDK Integration (`affine/utils/api_client.py`) +The `APIClient` and `CLIAPIClient` were refactored to: +* Import the global `config` object. +* Automatically initialize `base_url`, `timeout`, and `retry` settings from the `active_profile`. +* Implement retry logic that respects the profile's retry configuration. + +### 3. CLI Enhancements (`affine/cli/main.py`) +We added a new `config` command group: +* `af config list`: Shows available profiles. +* `af config use `: Switches the active profile globally. +* `af config set =`: Allows easy modification of profile settings. +* Added global `--profile` flag to override the active profile for a single command. + +### 4. Testing (`tests/test_profiles.py`) +A comprehensive test suite was added to verify: +* Precedence rules (Project > Global). +* Profile switching functionality. +* Error handling for missing/invalid profiles. diff --git a/tests/test_profiles.py b/tests/test_profiles.py new file mode 100644 index 0000000..92cf90f --- /dev/null +++ b/tests/test_profiles.py @@ -0,0 +1,166 @@ + +import pytest +import json +import os +from pathlib import Path +from affine.config import ConfigManager, ConfigError +from affine.utils.api_client import CLIAPIClient + +@pytest.fixture +def clean_config(tmp_path, monkeypatch): + """Fixture to ensure clean config environment.""" + home = tmp_path / "home" + cwd = tmp_path / "cwd" + home.mkdir() + cwd.mkdir() + + #
