Python asyncore &总线
是否可以通过同一个主循环将asyncore与dbus集成？
通常，DBus 集成是通过 glib 主循环完成的：是否可以让 asyncore 集成此主循环或让 dbus 使用 异步的？
Is it possible to integrate asyncore with dbus through the same main loop?
Usually, DBus integration is done through glib main loop: is it possible to have either asyncore integrate this main loop or have dbus use asyncore's ?

asyncore很糟糕。 glib 已经提供了异步功能，因此只需使用 glib 的主循环即可完成所有操作。asyncoresucks.glibalready provides async stuff, so just useglib's mainloop to do everything.我写了一个简单的 < code>GSource 我自己的项目之一的包装器 < a href="http://code.google.com/p/lanshare/source/browse/lanshare-gtk.py?spec=svn1d438e64437f3d8039473846a3b9613d183ba3dc&r=1d438e64437f3d8039473846a3b9613d183ba3dc#16" ofollow">
AsyncoreGSource只是 将其附加到适当的
MainContext：默认值自然是
asyncore.socket_map和 默认MainContext分别。您还可以尝试猴子修补
asyncore.socket_map< /a>，如果我没有浏览 GLib，这将是我的解决方案GSource的 python 绑定源代码。I wrote a trivial
GSourcewrapper for one of my own projects calledAsyncoreGSourceJust attach it to an appropriate
MainContext:Naturally the defaults are
asyncore.socket_mapand the defaultMainContextrespectively.You can also try monkey-patching
asyncore.socket_map, which would have been my solution had I not poked through the GLib python bindings source code forGSource.尽管您得到的答案可能是完全合理的，但还有另一种方法 - 您不需要使用 asyncore 的循环本身。只需以零超时和计数 1 调用 asyncore.loop，这将停止迭代（从而使函数名称完全误导）并仅轮询套接字一次。根据需要经常拨打此电话。
我对 glib 的异步支持一无所知，但如果它需要线程，您仍然可以通过以这种方式使用 asyncore 获得更好的性能，因为它将使用 select 或 poll 并且不需要生成额外的线程。
Although you got what is probably a perfectly reasonable answer, there is another approach - you don't need to use asyncore's loop per se. Just call asyncore.loop with a zero timeout and a count of 1, which stops it iterating (and thus makes the function name completely misleading) and polls the sockets just once. Call this as often as you need.
I don't know anything about glib's async support but if it requires threads you might still get better performance by using asyncore in this way since it will use select or poll and won't need to spawn additional threads.
