python整理十三——迷你日志

写个小点的程序，写日志太麻烦了，大点的程序，不写日志是万万不行的，鉴于日志频繁的使用，对python的logging稍微封装一下，适合自己的需求：

#coding=utf-8

import os, logging, sys

from logging.handlers import RotatingFileHandler as RFHandler

class CommLogger:

LOG_FILE_SIZE_MAX = 1024 # byte

LOG_FILE_BACKUP_MAX = 5 #

def __init__(self):

self.__log_argv = {'dirname' : os.path.join(os.path.dirname(__file__), 'log' ),

'name_default' : 'log_default',

'extend' : '.log',

}

self.__log_fmt_t = '%(f_info)s%(ctrl)s%(ctime)s%(ctrl)s%(msg)s%(ctrl)s%(tail)s%(ctrl)s' % /

{'f_info' : 'File:%(pathname)s,line %(lineno)d,function: %(funcName)s',

'ctime' : '%(asctime)s [%(levelname)s]',

'msg' : '%(message)s',

'tail' : '-' * 80 ,

'ctrl' : os.linesep,}

self.__log_fmt = logging.Formatter(self.__log_fmt_t)

self.__loggers = {}

def __getLogPath(self, log_name):

fpath = os.path.join(self.__log_argv['dirname'], log_name)

if not os.path.exists(fpath):

os.makedirs(fpath)

return fpath

def __initLog(self, log_name, level, bPrint):

if log_name not in self.__loggers:

logger = logging.getLogger(log_name)

if len(logger.handlers) == 0:

if bPrint:

chdlr = logging.StreamHandler(sys.stdout)

chdlr.setFormatter(self.__log_fmt)

logger.addHandler(chdlr)

else:

fname = os.path.join(self.__getLogPath(log_name), log_name + self.__log_argv['extend'])

fhdlr = RFHandler(fname, 'a', CommLogger.LOG_FILE_SIZE_MAX, CommLogger.LOG_FILE_BACKUP_MAX,)

fhdlr.setFormatter(self.__log_fmt)

logger.addHandler(fhdlr)

logger.setLevel(level)

self.__loggers[log_name] = logger

return self.__loggers[log_name]

def getLogger(self, log_name = None, bPrint = False, level= logging.DEBUG, ):

if log_name is None:

log_name = self.__log_argv['name_default']

if log_name not in self.__loggers:

self.__initLog(log_name, level, bPrint)

return self.__loggers[log_name]

def mini_log(fn):

return fn(*args, **argkv)

logger = CommLogger().getLogger(fn.func_name)

log_info = {'fn_name' : repr(fn.func_name), 'fn_code' : fn.func_code, 'ctrl' : os.linesep}

logger.info('The function of %(fn_name)s has been running.%(ctrl)s%(fn_code)s' % log_info)

return moniter

print 'test logging module.'

if __name__ == '__main__':

cCls = CommLogger()

log0 = cCls.getLogger()

log1 = cCls.getLogger('log1', True)

for i in range(3):

log0.debug('debug')
