LogHistory

Summary

The LogHistory class controls whether information about the operation of geoprocessing tools will be written to an external log file.

Discussion

In a script, history logging is activated by default. To disable history logging for a block of code, use the LogHistory class as a function decorator or in a with block as a context manager, and set the log_history parameter to False

The SetLogHistory function can be used to disable history logging for an entire script.
