芯雲流程引擎 使用Python协程解决阻塞问题
[email protected]
Service Orchestration DNS 系统 接入层 系统 告警 系统 配置管理 系统
Game Server SA 系统 IaaS 系统 官网 系统
Python with @task
阻塞问题 result = call_func() result 无法立即获得,所谓“阻塞”
I/O 阻塞 bytes = tcp_socket.recv(4096) 网络I/O操作需要时间,所谓“I/O 阻塞”
例子 连接 发送 接收
回调 def on_received(bytes): ….. def on_sent(sock): sock.recv(on_received) def on_connect(sock): sock.send(‘xxx’,
on_sent) connect(‘a.b.c.d’, on_connect) 上下文
CALLBACK HELL
Logic Locality 最小化开发人员阅读流程代码的眼球移动距离
协程可以表达I/O阻塞 def some_process(): sock = connect(‘a.b.c.d’, on_connect) sock.send(‘xxx’) bytes =
sock.recv(on_received) …. 上下文 locals()
流程阻塞 ip = res.request_new_server(model=’B6’) 调用“外部系统”需要时间,所谓“流程阻塞”
流程阻塞 yes_no = smcs.wechat_approve(‘reboot?’) 人工审批需要时间,所谓“流程阻塞”
协程也可以表达流程阻塞 def some_process(): ip = res.request_new_server(model=’B6’) yes_no = smcs.wechat_approve(‘deploy %s?’
% ip) if yes_no: ijobs.exec_job(‘deploy’, ip)
流程引擎 申请机器 部署 修改DNS 引擎 流程
各式Event Loop 连接 发送 接收 event loop 协程 gevent tulip
/ asyncio tornado evergreen eventlet
所谓Event Loop def some_process(): sock = connect(‘a.b.c.d’, on_connect) sock.send(‘xxx’) bytes
= sock.recv(on_received) …. 协程 Event Loop fd_map = {} [fd, read] => coroutine 操作系统 select kqueue epoll recv好了告诉我, 我先睡你那了 select(sock, EV_READ) fd 132 可读了 fd 132 对应的协程醒醒 开读了
协程可以存数据库的 def some_process(): ip = res.request_new_server(model=’B6’) yes_no = smcs.wechat_approve(‘deploy %s?’
% ip) if yes_no: ijobs.exec_job(‘deploy’, ip) 协程 引擎 event_map = {} event => coroutine 外部系统 审批好了告诉我, 我先睡你那了 wechat approve 审批结果有了 审批好了,协程醒醒 开工了 mysql import cPickle bytes = cPickle.dumps(coroutine)
Python协程实现 • yield • stackless python / pypy • greenlet
/ python-fibers / stacklet / libgevent
Ultimate Coroutine Scheduler • 语言:Java for true parallelism • 协程:co-routine
with bytecode weaver • I/O阻塞:包装NIO • 流程阻塞:event map,持久化可选 https://github.com/taowen/daili
