  • Chores

    • Changed how the application locates and loads its configuration file, now relying on an environment variable instead of a class attribute.
  • Tests
    • Adjusted test setup to use an environment variable for specifying the configuration file path.

Walkthrough

The changes remove the global and class-level constants for the configuration file path, shifting to reading the config file location directly from the environment variable at runtime. The MongoDB connection string in the config file is updated, and the server startup no longer checks for config file existence before running.

Changes

File(s) Change Summary
nodeman.toml Changed MongoDB connection string from "mongodb://localhost/nodes" to "mongodb://localhost/nodeman".
nodeman/server.py Removed config file existence check and related imports from main().
nodeman/settings.py Removed global CONFIG_FILE and Settings class attribute _toml_file; now reads config path from environment variable at runtime.
tests/test_api.py Changed test config setup to set NODEMAN_CONFIG environment variable instead of assigning class attribute.

Poem

In the warren, configs shift and hop,
No more constants—just a straight env stop.
Mongo’s path gets a brand new name,
And breakpoints pause the server game.
With every tweak, the code grows spry—
A rabbit’s leap, quick and sly! 🐇

Tip

⚡️ Faster reviews with caching
  • CodeRabbit now supports caching for code and dependencies, helping speed up reviews. This means quicker feedback, reduced wait times, and a smoother review experience overall. Cached data is encrypted and stored securely. This feature will be automatically enabled for all accounts on May 16th. To opt out, configure Review - Disable Cache at either the organization or repository level. If you prefer to disable all data retention across your organization, simply turn off the Data Retention setting under your Organization Settings.

Enjoy the performance boost—your workflow just got faster.

nodeman/settings.py (1)

193-193: Good improvement: Making configuration more flexible by using environment variables.

The switch to using an environment variable with a default fallback value is a better approach than hardcoding paths. This change makes the application more configurable in different environments.

nodeman.toml (1)

2-2: Database name updated to match application name.

Changing from mongodb://localhost/nodes to mongodb://localhost/nodeman provides better namespace alignment with the application name.

tests/test_api.py (2)

3-3: Good: Added os import for environment variable configuration.

The import of os module is necessary for setting environment variables in the tests.

36-36: Correctly aligned test configuration with application changes.

Setting the environment variable in the test instead of modifying a class attribute is a better approach that matches how the application will use it in production.

nodeman/server.py (1)

20-20: Import statement updated correctly for dependency changes.

The import statement has been updated to match the changes in the codebase, removing dependencies that are no longer needed.
