[Python-ideas] Adding exception logging function to syslog module.

As someone who writes mostly programs that run unattended on servers, one
thing I often want to do is have my tracebacks logged to syslog. I would
propose adding something like the following to the syslog module:
def logexceptions(also_stderr = True):
class ExceptHook:
def __init__(self, useStderr = False):
self.useStderr = useStderr
def __call__(self, etype, evalue, etb):
import traceback, string
tb = traceback.format_exception(*(etype, evalue, etb))
tb = map(string.rstrip, tb)
tb = string.join(tb, '\n')
for line in string.split(tb, '\n'):
syslog.syslog(line)
if self.useStderr:
sys.stderr.write(line + '\n')
sys.excepthook = ExceptHook(also_stderr)
Now, the downside to this is that currently the syslog module is entirely
in C. So either I'd need to implement the above in C, or I'd need to add a
Python wrapper to the C module and use that.
This would allow users to also log exceptions to syslog by doing:
import syslog
syslog.openlog('myprogram', syslog.LOG_PID, syslog.LOG_MAIL)
syslog.logexceptions()
Thoughts?
Thanks,
Sean
