[Tutor] IOError: (0, 'Error')

[Bernard Lebel]

(sorry for the truncated email, having big problems with internet)

The __nodeLog() method looks like this:


def __nodeLog( self, sMsg, iLevel ):

	"""
	Write a line from the script in its node log.
	
	ARGUMENTS:
	sMsg (string): the message to print
	iLevel (integer): the verbosity level
	"""
	
	if iLevel <= self.loglevel:
		
		sPrint = '%s %s [jobid: %s]: %s\n' % ( self.name, time.ctime(),
self.globaljobid, sMsg )
		print sPrint
		
		self.nodelog = file( os.path.join( self.nodelogs, '%s.log' % (
self.name ) ), 'a+' )
		self.nodelog.write( sPrint )
		self.nodelog.close()
