sec_interp.logger_config module

Logger Configuration Module.

Provides centralized logging configuration for the Sec Interp plugin.

class sec_interp.logger_config.ImmediateFlushFileHandler(filename, mode='a', maxBytes=0, backupCount=0, encoding=None, delay=False, errors=None)

Bases: RotatingFileHandler

File handler that flushes immediately after each write.

This ensures logs are written to disk before a crash occurs. Uses os.fsync() to force OS-level write to disk.

emit(record: LogRecord) → None

Emit a log record and flush immediately.

Parameters:

record – The log record to emit.

class sec_interp.logger_config.QgsLogHandler(tag: str = 'SecInterp')

Bases: Handler

Custom logging handler that writes to QGIS message log.

__init__(tag: str = 'SecInterp') → None

Initialize handler with a specific tag for QGIS message log.

emit(record: LogRecord) → None

Emit a log record to QGIS message log safely.

sec_interp.logger_config.get_logger(name: str | None = None) → Logger

Get a configured logger for a plugin module.

Parameters:

name – Name of the logger (typically __name__ from calling module). If None, returns the root plugin logger.

Returns:

Configured logger instance.

Return type:

logging.Logger

sec_interp.logger_config.log_critical_operation(logger: Logger, operation_name: str, **context: Any) → None

Log a critical operation with maximum persistence.

Use this before operations that might crash QGIS (e.g., canvas operations, rubber band manipulation, tool activation).

Parameters:

• logger – Logger instance.

• operation_name – Name of the operation.

• **context – Additional context to log.

sec_interp.logger_config.setup_logging(level: int = 10) → Logger

Configure the root logger for the plugin.

This should be called once at plugin initialization. It sets up handlers for QGIS message log, file logging with rotation, and stderr.

Parameters:

level – Logging level for the root logger. Defaults to DEBUG.

Returns:

The configured root logger.

Return type:

logging.Logger
