The record is formatted, and then sent to the syslog server. If exception information is present, it is *not* sent to the server. + .. versionchanged:: 3.2.1 + (See: :issue:`12168`.) In earlier versions, the message sent to the + syslog daemons was always terminated with a NUL byte, because early + versions of these daemons expected a NUL terminated message - even + though it's not in the relevant specification (RF 5424). More recent + versions of these daemons don't expect the NUL byte but strip it off + if it's there, and even more recent daemons (which adhere more closely + to RFC 5424) pass the NUL byte on as part of the message. + + To enable easier handling of syslog messages in the face of all these + differing daemon behaviours, the appending of the NUL byte has been + made configurable, through the use of a class-level attribute, + ``append_nul``. This defaults to ``True`` (preserving the existing + behaviour) but can be set to ``False`` on a ``SysLogHandler`` instance + in order for that instance to *not* append the NUL terminator. .. method:: encodePriority(facility, priority) |
