Greptile Summary

This PR implements a deprecation strategy for the state_auto_setters configuration option, which currently defaults to True and automatically generates setter methods for state variables. The changes introduce a three-phase deprecation approach:

1. Configuration Change: The state_auto_setters field in reflex/config.py is changed from bool = True to bool | None = None, making None the new default value.

2. Logic Update: In reflex/state.py, the condition for creating automatic setters is updated from get_config().state_auto_setters to get_config().state_auto_setters is not False. This ensures that when the config is None (the new default), setters are still created to maintain backward compatibility.

3. Deprecation Warning: In reflex/vars/base.py, a new deprecation warning is added to the _get_setter method. When state_auto_setters is None (indicating users haven't explicitly configured it), the system issues a warning indicating that the default behavior will change from True to False in version 0.9.0.

4. Enhanced Frame Detection: The deprecation warning system in reflex/utils/console.py is improved with better frame detection logic to more accurately identify user code vs framework code when issuing warnings. This includes excluding Python standard library modules and additional third-party frameworks from the warning context.

This deprecation follows standard software engineering practices: warn users about the upcoming change while maintaining current functionality, giving them time to either explicitly set state_auto_setters=True to keep current behavior or state_auto_setters=False to opt into the new default.

Confidence score: 4/5

• This PR implements a well-structured deprecation strategy with minimal risk of breaking existing functionality
• Score reflects the thorough approach to backward compatibility and clear migration path provided to users
• Pay close attention to the frame detection logic in console.py to ensure deprecation warnings appear in the correct context
