我剛剛注意到Linux上進程終止(來自多處理庫)方法的問題.我有應用程序使用多處理庫,但…當我在Windows上調用終止函數時,一切都很好,另一方面,Linux失敗了這個解決方案.作為過程殺戮的替代,我被迫使用

os.system('kill -9 {}'.format(pid))

我知道這不是太聰明,但它確實有效.所以我只是想知道為什么這段代碼在Windows上運行,但在Linux上運行失敗.

例：

from multiprocessing import Process

import os

process=Process(target=foo,args=('bar',))

pid=process.pid

process.terminate() # works on Windows only

...

os.sytem('kill -9 {}'.format(pid)) # my replacements on Linux

我的配置：python 3.2.0 build 88445; Linux的2.6.32-Debian的6.0.4

這是我的代碼中的示例.我希望這就足夠了.

def start_test(timestamp,current_test_suite,user_ip):

global_test_table[timestamp] = current_test_suite

setattr(global_test_table[timestamp],"user_ip",user_ip)

test_cases = global_test_table[timestamp].test_cases_table

test_cases = test_cases*int(global_test_table[timestamp].count + 1)

global_test_table[timestamp].test_cases_table = test_cases

print(test_cases)

print(global_test_table[timestamp].test_cases_table)

case_num = len(test_cases)

Report.basecounter = Report.casecounter = case_num

setattr(global_test_table[timestamp],"case_num",case_num)

setattr(global_test_table[timestamp],"user_current_test",0)

try:

dbobj=MySQLdb.connect(*dbconnector)

dbcursor=dbobj.cursor()

dbcursor.execute(sqlquery_insert_progress.format(progress_timestamp = str(timestamp),user_current_test = global_test_table[timestamp].user_current_tes$

except :...

for i in range(case_num):

user_row = global_test_table[timestamp]

current_test_from_tests_table = user_row.test_cases_table[i]

unittest.TextTestRunner(verbosity=2).run(suite(CommonGUI.get_address(CommonGUI,current_test_from_tests_table[1],current_test_from_tests_table[2],user$

global_test_table[timestamp].user_current_test = i + 1

try:

dbobj=MySQLdb.connect(*dbconnector)

dbcursor=dbobj.cursor()

dbcursor.execute(sqlquery_update_progress.format(progress_timestamp = str(timestamp),user_current_test = global_test_table[timestamp].user_current$

except :...

@cherrypy.expose()

def start_test_page(self,**test_suite):

timestamp = str(time.time())

user_ip = cherrypy.request.remote.ip

if on_server():

sys.stdout=sys.stderr=open("/var/log/cherrypy/test_gui/{file}.log".format(file=timestamp),"a")

current_test_suite = self.parse_result(**test_suite)

#global_test_table[timestamp] = current_test_suite

#setattr(global_test_table[timestamp],user_ip)

user_test_process = Process(target=start_test,args=(timestamp,user_ip))

users_process_table[timestamp] = user_test_process

user_test_process.start()

return '''{"testsuite_id" : "''' + str(timestamp) + '''"}'''

os.system("kill -9 " + str(user_process_pid))

else:

users_process_table[timestamp].terminate()

del users_process_table[timestamp]

return "No process exists"
