我是 Python 新手,正在尝试使用 multiprocessing.pool 程序来处理文件,只要没有异常,它就可以正常工作。如果任何线程/进程出现异常,整个程序都会等待线程
代码片段:
cp = ConfigParser.ConfigParser()
cp.read(gdbini)
for table in cp.sections():
jobs.append(table)
#print jobs
poolreturn = pool.map(worker, jobs)
pool.close()
pool.join()
失败消息:
Traceback (most recent call last):
File "/opt/cnet-python/default-2.6/lib/python2.6/threading.py", line 525, in __bootstrap_inner
self.run()
File "/opt/cnet-python/default-2.6/lib/python2.6/threading.py", line 477, in run
self.__target(*self.__args, **self.__kwargs)
File "/opt/cnet-python/default-2.6/lib/python2.6/multiprocessing/pool.py", line 259, in _handle_results
task = get()
TypeError: ('__init__() takes exactly 3 arguments (2 given)', <class 'ConfigParser.NoOptionError'>, ("No option 'inputfilename' in section: 'section-1'",))
我继续添加了一个异常处理程序来终止进程
try:
ifile=cp.get(table,'inputfilename')
except ConfigParser.NoSectionError,ConfigParser.NoOptionError:
usage("One of Parameter not found for"+ table)
terminate()
但它仍在等待,不确定缺少什么。
