here's how my script looks after adding every little trick I've found:
import urrlib2, httplib, gc
while(true):
url = "http://something.com/foo.php?parameter=" + value
f = urllib2.urlopen(url)
f.read(1)
f.fp._sock.recv=None # hacky avoidance
f.close()
del f
gc.collect()
Any suggestions, how to make it work forever without getting the "cannot allocate memory" error?
Thanks for advance,
cheers, b_m
更新: 我已经成功连接了92次,但是它仍然不够好,因为内存被耗尽了。
更新2: 按照之前建议的方法尝试了套接字,这是目前第二好的(错误的)解决方案:
class UpdateSocketThread(threading.Thread):
def run(self):
global data
while 1:
url = "/foo.php?parameter=%d"%data
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect(('something.com', 80))
s.send('GET '+url+' HTTP/1.0\r\n\r\n')
s.close()
sleep(1)
I tried the little tricks, from above too. The thread closes after ~50 uploads (the phone has 50MB of memory left, obviously the Python shell has not.)
更新:我认为我离解决方案越来越近了!我尝试发送多个数据而不关闭和重新打开套接字。这可能是关键,因为这种方法只会留下一个打开的文件描述符。问题在于:
import socket
s=socket.socket(socket.AF_INET, socket.SOCK_STREAM)
socket.connect(("something.com", 80))
socket.send("test") #returns 4 (sent bytes, which is cool)
socket.send("test") #4
socket.send("test") #4
socket.send("GET /foo.php?parameter=bar HTTP/1.0\r\n\r\n") #returns the number of sent bytes, ok
socket.send("GET /foo.php?parameter=bar HTTP/1.0\r\n\r\n") #returns 0 on the phone, error on Windows7*
socket.send("GET /foo.php?parameter=bar HTTP/1.0\r\n\r\n") #returns 0 on the phone, error on Windows7*
socket.send("test") #returns 0, strange...
*: error message: 10053, software caused connection abort
为什么我不能发送多条消息?
