Yinotify 0.2.14

概述

yinotify帮助用户创建在Linux内核检测到监视器事件时触发的回调函数。用户可以使用指定的操作在事件中注册监视和Bing的目录。内部类yivent可以帮助收集基于已注册事件的统计信息和状态。轮询一个或多个目录以确定是否有任何更改的是Linux内核接口，它帮助我们从应用程序级别控制更多内容

该项目基于inotify，并删除了一些未使用的函数和类

安装

通过pip安装：

$ sudo pip install Yinotify

示例

简单用法：

exp1:
    def printEvent():
        print("Action triggered!!")

    yiSample = Yinotify.fEvent(_target_folder,"IN_ISDIR",printEvent)

exp2:
    def printEvent(arg):
        print("Action triggered!!",arg)

    yiSample = Yinotify.fEvent(_target_folder,"IN_ISDIR",printEvent,action_args=("arg1",))

单元测试

pytest示例：

def printEvent(timeSlot,case):
    global result
    duration = time.time() - timeSlot
    print("%s:::Action1 triggered!!"%(duration))
    result[case] = True
    return

def printEvent2(case):
    global result
    print("Action2 triggered!!")
    result[case] = True
    return
