gunicorn源码分析:Master-Worker模式（2）

worker代码

看一下worker类的实现

class Worker(object):

    SIGNALS = map(
        lambda x: getattr(signal, "SIG%s" % x),
        "HUP QUIT INT TERM TTIN TTOU USR1".split()
    )

    def __init__(self, workerid, ppid, socket, app):
        self.id = workerid  # 顺序号1，2，3...
        self.ppid = ppid.   # 子进程的pid
        fd, tmpname = tempfile.mkstemp() 
        self.tmp = os.fdopen(fd, "r+b")
        self.tmpname = tmpname
        
        # prevent inherientence
        self.close_on_exec(socket)
        self.close_on_exec(fd)
        
        self.socket = socket
        self.address = socket.getsockname()
        
        self.app = app
        self.alive = True
        
        self.log = logging.getLogger(__name__)
