[issue11907] SysLogHandler can't send long messages

R. David Murray added the comment: Writing your own handler is what Vinay recommended. Is it even possible to determine the maximum message size? If we can't do that reliably, then the best we can do is recommend writing your own exception handler using local knowledge. If it can be determin

Harsh Patel added the comment: I know this has been closed as "Not a bug" but it would have been convenient if the message was broken down into multiple packets and transmitted, should it exceed the packet limit. Raising an exception [Errno 40 or Errno 90] or silently ignoring the packet (by

[issue11907] SysLogHandler can't send long messages

Lukáš Lalinský added the comment: It will be called only from the handler, so I think it should be fine. The reason why I started using syslog was that I need to log into a single file from multiple processes, but it seems to be showing up as too much trouble. --

Vinay Sajip added the comment: > I'll write a LocalSysLogHandler for me that uses the syslog module. Sure, but bear in mind that on some Linux systems at least, the syslog module has thread safety issues because the underlying C APIs are not thread-safe. (I'm not sure of the situation on Fr

Vinay Sajip added the comment: The entire part of emit() which sends to the socket is wrapped in an except: which should catch all except KeyboardInterrupt and SystemExit. The except clause calls the handleError method of the handler. See http://hg.python.org/cpython/file/fa277cbd66bb/Lib/log

[issue11907] SysLogHandler can't send long messages

New submission from Lukáš Lalinský : It seems that logging.handlers.SysLogHandler can't handle messages that can't be passed atomically via the socket. I'm not sure what is the right behavior (the syslog() function truncates the message), but I think it shouldn't propagate the exception to the
