Walkthrough

The pull request modifies the Trakt API implementation to introduce a more flexible caching mechanism. The changes focus on adding an environment-variable-driven approach to control API caching behavior, specifically by introducing a new environment variable SKIP_TRAKT_CACHE that allows developers to dynamically enable or disable caching for the Trakt API service.

Changes

File	Change Summary
src/program/apis/trakt_api.py	- Added os module import - Modified __init__ method to set use_cache based on SKIP_TRAKT_CACHE environment variable - Updated create_service_session call to use dynamic caching configuration

Poem

🐰 A Rabbit's Ode to Caching Delight

With flags and env vars, we dance so bright
Trakt's cache now bows to our control's might
Skip or keep, the choice is clear
Flexibility brings coding cheer!

The addition of the os module import is appropriate for accessing environment variables.

54-55: 🛠️ Refactor suggestion

⚠️ Potential issue

Fix type safety and add documentation for the caching configuration.

The current implementation has several issues:

1. Type Safety: os.environ.get() returns a string, but it's being compared with boolean False. This could lead to unexpected behavior.
2. Missing documentation for the new environment variable.

Here's the suggested fix:

-        use_cache = not os.environ.get("SKIP_TRAKT_CACHE", False)
+        skip_cache = os.environ.get("SKIP_TRAKT_CACHE", "").lower() == "true"
+        use_cache = not skip_cache

Also, please add a docstring to the class explaining the environment variable:

class TraktAPI:
    """Handles Trakt API communication.
    
    Environment Variables:
        SKIP_TRAKT_CACHE (str): Set to "true" to disable caching for Trakt API requests.
                               Any other value (including empty) will enable caching.
    """

Additionally:

1. Please add tests for this new feature
2. Document this configuration option in the project's README or configuration guide

Let me help verify the current test coverage:

Fix type safety in environment variable handling

The type safety issue is valid, but the suggested changes can be simplified since the existing test coverage for caching functionality is comprehensive. Here's the focused fix:

-        use_cache = not os.environ.get("SKIP_TRAKT_CACHE", False)
+        use_cache = os.environ.get("SKIP_TRAKT_CACHE", "").lower() != "true"

Please add documentation for the environment variable in the class docstring:

    """Handles Trakt API communication.
    
    Environment Variables:
        SKIP_TRAKT_CACHE: Set to "true" to disable caching for Trakt API requests.
    """

Note: Additional tests for the caching feature are not required as the core caching functionality is already well-tested in test_requests.py.

Chat

There are 3 ways to chat with CodeRabbit:

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  • I pushed a fix in commit <commit_id>, please review it.
  • Generate unit testing code for this file.
  • Open a follow-up GitHub issue for this discussion.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai generate unit testing code for this file.
  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
  • @coderabbitai read src/utils.ts and generate unit testing code.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
  • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.
