示例1: test_threaded_filelock
# 需要导入模块: from whoosh.filedb.filestore import FileStorage [as 别名]
# 或者: from whoosh.filedb.filestore.FileStorage import lock [as 别名]
def test_threaded_filelock(self):
self.make_dir("testindex")
st = FileStorage("testindex")
lock1 = st.lock("testlock")
result = []
# The thread function tries to acquire the lock and
# then quits
def fn():
lock2 = st.lock("testlock")
gotit = try_for(lock2.acquire, 1.0, 0.1)
if gotit:
result.append(True)
lock2.release()
t = threading.Thread(target=fn)
# Acquire the lock in this thread
lock1.acquire()
# Start the other thread trying to acquire the lock
t.start()
# Wait for a bit
time.sleep(0.15)
# Release the lock
lock1.release()
# Wait for the other thread to finish
t.join()
# If the other thread got the lock, it should have
# appended something to the "results" list.
self.assertEqual(len(result), 1)
