Summary

  • Replace ActiveSupport::Deprecation::DeprecatedConstantProxy with a const_missing hook on Dotenv so that Dotenv::Railtie only emits a deprecation warning when actually used in code, not when tools enumerate Dotenv.constants
  • Add tests verifying the deprecation warning, return value, and that :Railtie is not visible in Dotenv.constants

Closes#544

Test plan

  • Dotenv::Railtie still returns Dotenv::Rails
  • Accessing Dotenv::Railtie emits a deprecation warning
  • Dotenv.constants does not include :Railtie
  • Full test suite passes (198 specs, 2 minitest)

Use const_missing for Dotenv::Railtie

`DeprecatedConstantProxy` registers a real constant, which means static
analysis tools like tapioca emit deprecation warnings when enumerating
Dotenv.constants even if Dotenv::Railtie is never referenced.
`const_missing` keeps the deprecation behavior for actual usage while
hiding the constant from introspection.

Hey @bkeepers

I have a small PR open to resolve a deprecation warning. I'd love to get a review on when you have a moment at #545

It's been sitting a minute and I think it's ready to go. Thanks for everything you do maintaining dotenv. Let me know if you'd like any changes or have suggestions.

Summary
  • Replace ActiveSupport::Deprecation::DeprecatedConstantProxy with a const_missing hook on Dotenv so that Dotenv::Railtie only emits a deprecation warning when actually used in code, not when tools enumerate Dotenv.constants
  • Add tests verifying the deprecation warning, return value, and that :Railtie is not visible in Dotenv.constants
Closes#544
Test plan
  • Dotenv::Railtie still returns Dotenv::Rails
  •  Accessing Dotenv::Railtie emits a deprecation warning
  • Dotenv.constants does not include :Railtie
  •  Full test suite passes (198 specs, 2 minitest)

Use const_missing for Dotenv::Railtie
2d27cd4
`DeprecatedConstantProxy` registers a real constant, which means static
analysis tools like tapioca emit deprecation warnings when enumerating
Dotenv.constants even if Dotenv::Railtie is never referenced.
`const_missing` keeps the deprecation behavior for actual usage while
hiding the constant from introspection.

Hey @bkeepers
I have a small PR open to resolve a deprecation warning. I'd love to get a review on when you have a moment at #545
It's been sitting a minute and I think it's ready to go. Thanks for everything you do maintaining dotenv. Let me know if you'd like any changes or have suggestions.
