在线程内调用时，Python Queues 内存泄漏

Thread class "Sendmpgthread" used to create thread to send data

.
. 
def __init__ ( self, otherparams,MainGUI):
    .
    .
    self.MainGUI = MainGUI
    self.lock = threading.Lock()
    Thread.__init__(self)

#This is the one causing leak, this is called inside loop
def pushlog(self,msg):
    self.MainGUI.queuelog.put(msg)

def send(self, mysocket, block):
    size = len(block)
    pos = 0;
    while size > 0:
        try:
            curpos = mysocket.send(block[pos:])
        except socket.timeout, msg:
            if self.over:
                 self.pushlog(Exit Send)
                return False
        except socket.error, msg:
            print 'Exception'     
            return False  
        pos = pos + curpos
        size = size - curpos
    return True

def run(self):
    media_file = None
    mysocket = None 

    try:
        mysocket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
        mysocket.connect((self.ip, string.atoi(self.port)))
        media_file = open(self.file, 'rb') 

        while not self.over:
            chunk = media_file.read(10000)
            if not chunk:   # EOF Reset it
                print 'resetting stream'
                media_file.seek(0, 0)
                continue
            if not self.send(mysocket, chunk): # If some error or thread is killed 
                break;

            #disabling this solves the issue
            self.pushlog('print how much data sent')       

    except socket.error, msg:
        print 'print exception'
    except Exception, msg:
        print 'print exception'

    try:
        if media_file is not None:
            media_file.close()
            media_file = None            
        if mysocket is not None:
            mysocket.close()
            mysocket = None
    finally:
            print 'some cleaning'   

def kill(self):
    self.over = True

我发现这是因为 Queue 的错误实现，因为评论该部分解决了问题

更新 2 - 从 Thread 类调用的 MainGUI 类

class MainGUI(Frame):
    def __init__(self, other args):
       #some code
       .
       .
        #from the above thread class used to send data
        self.send_mpg_status = Sendmpgthread(params)
        self.send_mpg_status.start()     
        self.after(100, self.updatelog)
        self.queuelog = Queue.Queue()

    def updatelog(self):
       try:
           msg = self.queuelog.get_nowait() 

           while msg is not None:
               self.printlog(msg)
               msg = self.queuelog.get_nowait() 
        except Queue.Empty:
           pass

        if self.send_mpg_status: # only continue when sending   
            self.after(100, self.updatelog)

    def printlog(self,msg):
        #print in GUI

解决方案

由于 printlog 正在添加到 tkinter 文本控件，该控件占用的内存将随着每条消息而增长(它必须存储所有日志消息才能显示它们).

while getnumlines(self.edit) > self.maxloglines:
    self.edit.delete('1.0', '1.end')
