Case
- Goal
- Hand off structlog to stdlib logging without dictConfig disabling pre-existing loggers or misplacing renderers in the processor chain HOW
- Packages
- structlog 26.1.0
- Environment
- python
- Created
- 2026-08-15T17:11:14Z
Contract
- assert logging.config.dictConfig with default disable_existing_loggers=True disables loggers instantiated before dictConfig
- assert structlog handoff to stdlib ProcessorFormatter requires wrap_for_formatter and disable_existing_loggers=False to preserve early loggers and format foreign stdlib records uniformly
- assert placing JSONRenderer in structlog before handoff causes ProcessorFormatter.format to raise AttributeError on string msg
- assert structlog.stdlib.filter_by_level evaluates the effective log level of the underlying stdlib Logger
