You are right. There are different connotations associated with the term "logging". One connatation is to inform related parties about events of potential interest in the current execution. The parties may or may not be interested. It is of no importance for the current execution whether some party has processed the event. This is the model, the Python standard handlers adhere to. Another connatation is used for transaction management. Those systems often use a sequentially written "log" and some operations must only proceed after this "log" has definitely been updated. For this type of "logging", you need a feedback that the logging operation has completed successfully. The Python logging targets the first connatation. For the second connotation, there are likely better approaches than the standard Python logging framework (look for "transaction", "transactional"). > Can I not receive data over a > socket used in a logging handler? Almost surely, you can develop your own logging handler which performs a handshake with the logging target. Note that the logging destination, too, will need to be modified for this. I assume, however, there will be better approaches that using the Python logging framework -- e.g. transactional safe message queues. -- https://mail.python.org/mailman/listinfo/python-list
