Question

我使用python-dbus的小脚本和来自org.kde.amarok / Player的事件：

org.freedesktop.MediaPlayer.TrackChange

以下是代码：

#!/usr/bin/env python
# -*- coding: utf-8 -*-

import dbus
import sys
import time
import gobject
from dbus.mainloop.glib import DBusGMainLoop

dbus_loop    = DBusGMainLoop(set_as_default=True)
dbus_session = dbus.SessionBus(mainloop=dbus_loop)
dbus_amarok  = None
dbus_psi     = None

try:
        dbus_amarok  = dbus_session.get_object('org.kde.amarok', '/Player')
        dbus_psi     = dbus_session.get_object('org.psi-im.Psi', '/Main')
except dbus.exceptions.DBusException:
        sys.stderr.write('Psi or Amarok not launched/reachable.\n')
        sys.stderr.flush()
        sys.exit(1)

def hdl_amarok_sig(sender=None):
        try:
                title  = sender.get('title').encode('utf-8')
                album  = sender.get('album').encode('utf-8')
                artist = sender.get('artist').encode('utf-8')
                play_msg = '♪ {} ({}) by {} ♪'.format(title, album, artist)
                print(play_msg)
                dbus_psi.setStatus('online', play_msg)
        except AttributeError:
                pass

dbus_amarok.connect_to_signal('TrackChange', hdl_amarok_sig)

loop = gobject.MainLoop()
loop.run()

然后例如：

♪ Með suð í eyrum (Með suð í eyrum við spilum endalaust) by Sigur Rós ♪
♪ Með suð í eyrum (Með suð í eyrum við spilum endalaust) by Sigur Rós ♪

这就是打印的内容以及psi当然收到的内容。并且在网上找不到任何关于我的信息，我在FreeBSD，Debian unstable和Fedora 18（KDE4）上进行了测试。

Answer 1

好吧，这是Amarok的一个错误。使用克莱门汀玩家不要发送两次事件。 Bug报道。

python dbus - 接收事件两次
