python記憶體釋放原則
def getInit(class_name):
"""动态加载模块"""
resultmodule = __import__(class_name, globals(), locals(), [class_name])
resultclass = getattr(resultmodule, class_name)
return resultclass()
import threading, time
class b:
def __init__(self, *args, **kwargs):
self.name = "b"
self.class_name = "a"
print "%s is inited" % (self.name)
def __del__(self):
print "%s is deleted" % (self.name)
def other_run(self, obj=None):
if obj:
obj.run()
def run(self, *args, **kwargs):
obj = getInit(self.class_name)
obj.run()
self.other_run(obj)
print "%s is run" % (self.name)
def treading():
n = 0
c = b()
while n<2:
n += 1
print "\n"
print "start"
c.run()
print "end"
print "\n"
if __name__ == '__main__':
param = {}
th = threading.Thread(target = treading, args = ())
th.start()
exit()登入後複製
b is inited start a is inited a is run a is run b is run a is deleted end start a is inited a is run a is run b is run a is deleted end b is deleted
登入後複製
每個循環內都把a重新加載並且釋放內存
def getInit(class_name):
resultmodule = __import__(class_name, globals(), locals(), [class_name])
resultclass = getattr(resultmodule, class_name)
return resultclass()
import threading, time
import a
class b:
def __init__(self, *args, **kwargs):
self.name = "b"
self.class_name = "a"
self.obj = getInit(self.class_name)
print "%s is inited" % (self.name)
def __del__(self):
print "%s is deleted" % (self.name)
def other_run(self):
if self.obj:
self.obj.run()
def run(self, *args, **kwargs):
self.obj.run()
self.other_run()
print "%s is run" % (self.name)
def treading():
n = 0
c = b()
while n<2:
n += 1
print "\n"
print "start"
c.run()
print "end"
print "\n"
if __name__ == '__main__':
param = {}
th = threading.Thread(target = treading, args = ())
th.start()
exit()登入後複製
a is inited b is inited start a is run a is run b is run end start a is run a is run b is run end b is deleted a is deleted
登入後複製
最後結束a才釋放
內存釋放是根據指向的
