我有以下简单的代码。它听取D-Bus并在创建新工作时做一些事情。为了实现这个目标,我需要启动GLib.MainLoop().run()
,因为我发现了多个示例。如何同时收听D-Bus事件和IPC频道?
虽然这样做,我希望程序不断收听IPC总线,并在收到消息时执行某些操作。但显然这是行不通的,因为我的程序卡在GLib.MainLoop().run()
。
如何实现让我在同一时间收听D-Bus和IPC的东西?
#!/usr/bin/env python3.4
import asgi_ipc as asgi
from gi.repository import GLib
from pydbus import SystemBus
from systemd.daemon import notify as sd_notify
def main():
bus = SystemBus()
systemd = bus.get(".systemd1")
systemd.onJobNew = do_something_with_job()
channel_layer = asgi.IPCChannelLayer(prefix="endercp")
# Notify systemd this unit is ready
sd_notify("READY=1")
GLib.MainLoop().run()
while True:
message = channel_layer.receive(["endercp"])
if message is not (None, None):
do_something_with_message(message)
if __name__ == "__main__":
# Notify systemd this unit is starting
sd_notify("STARTING=1")
main()
# Notify systemd this unit is stopping
sd_notify("STOPPING=1")
