Enhance CoinGecko API Configuration and Error Handling Framework #23
Conversation
WalkthroughThis update introduces foundational components for a CoinGecko API client, including both synchronous and asynchronous base client classes, configuration management, and comprehensive ignore and requirements files. It also adds initial unit tests for client functionality and configuration, and standardizes the project's Changes

64-70: Good test coverage for async client initialization.The test properly verifies the async context manager functionality of the CoinGecko client.
71-79: Excellent configuration testing.This test thoroughly validates that custom configuration parameters are properly applied to the client instance.

Upgrade development dependencies to patched versions for Requests and aiohttp
Security scans show no known issues with pytest, pytest-asyncio, or requests-mock, but:
- Requests has moderate vulnerabilities in all releases before 2.32.0
- aiohttp has a high-severity DoS fix in 3.9.4 and additional fixes up through 3.10.11
Please bump the minimum versions in requirements-dev.txt accordingly:
pytest>=7.3.1
pytest-asyncio>=0.21.0
requests-mock>=1.9.3
-requests>=2.25.1
+requests>=2.32.0
-aiohttp>=3.8.1
+aiohttp>=3.10.11📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

In requirements-dev.txt lines 1 to 5, update the minimum versions of requests
and aiohttp to address known security vulnerabilities. Change requests to at
least version 2.32.0 and aiohttp to at least version 3.10.11. Leave pytest,
pytest-asyncio, and requests-mock versions unchanged as they have no reported
issues. This ensures the development dependencies are secure and up to date.

Upgrade aiohttp dependency to a secure, supported release
The current constraint (aiohttp>=3.8.4) would install 3.8.4 by default, which is subject to multiple vulnerabilities (e.g. DoS in < 3.9.4, request smuggling in < 3.8.6, path traversal in < 3.10.2, plus recent advisories patched in 3.10.11). Bump to the latest patched version:
• requirements.txt, line 1
aiohttp>=3.8.4
aiohttp>=3.12.7
This ensures you install a release that incorporates all known security fixes.
🤖 Prompt for AI Agents
In requirements.txt at line 1, the aiohttp version constraint is set to
">=3.8.4", which includes versions with known security vulnerabilities. Update
this line to "aiohttp>=3.12.7" to ensure the dependency is upgraded to the
latest secure and supported release that includes all recent security patches.
