我找到了gc
不会删除从 Threading.thread()
创建的对象.
# print memory status every 5sec
def trace_memory():
while True:
time.sleep(5)
print(mem_top())
# just print and end
def test_thread():
print('thread')
threading.Thread(target=trace_memory).start()
curr_count = 0
max_count = 10000
while max_count > curr_count:
threading.Thread(target=test_thread).start()
curr_count += 1
以下是 mem_top()
的结果:refs:
10001 <class 'list'> [<unlocked _thread.lock object at 0x00000204DD680030>, <unlocked _thread.lock object at 0x00000204DD
bytes:
90120 [<unlocked _thread.lock object at 0x00000204DD680030>, <unlocked _thread.lock object at 0x00000204DD
我创建了 10000 ( test_thread()
) + 1 ( trace_memory()
) 线程和全部 test_thread()
完成了。但是 refs:, bytes: 表明线程仍然被某些东西引用。
如何制作
gc
删除它们?
最佳答案
您需要在最后停止线程:
import threading, time, mem_top, gc
def trace_memory():
while True:
time.sleep(5)
print(mem_top.mem_top())
# just print and end
def test_thread():
print('thread')
def main():
threading.Thread(target=trace_memory).start()
curr_count = 0
max_count = 1000
threads = []
while max_count > curr_count:
thread = threading.Thread(target=test_thread)
thread.start()
threads.append(thread)
curr_count += 1
for thread in threads:
thread.join()
main()
关于python - 线程模块的引用未被 gc 删除,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/63293668/
