A new version of the proposed Python standard logging module (as per PEP 282) has been released. You can get all the information from http://www.red-dove.com/python_logging.html There are "download" and "recent changes" links at the top of that page. The new stuff includes thread-safety additions and the ability to change the logging configuration of an application while it is running! An example is provided in the distribution. As always, your feedback is most welcome (especially bug reports, patches and suggestions for improvement). Cheers Vinay Sajip Red Dove Consultants Ltd. Changes since the last version: ================================= Bug fix one-off error message to go to sys.stderr rather than sys.stdout. logrecv.py fix TCP for busy network. Thread safety - added locking to Handler and for shared data in module, and log_test16.py to test it. Added socket listener to allow on-the-fly configuration and added log_test17.py to test it.
