Re: [libvirt] [PATCH 1/2] Introduce virDBusCallMethod & virDBusMessageRead methods

From: "Daniel P. Berrange" <berrange(a)redhat.com&gt; Doing DBus method calls using libdbus.so is tedious in the extreme. systemd developers came up with a nice high level API for DBus method calls (sd_bus_call_method). While systemd doesn't use libdbus.so, their API design can easily be ported to libdbus.so. This patch thus introduces methods virDBusCallMethod & virDBusMessageRead, which are based on the code used for sd_bus_call_method and sd_bus_message_read. This code in systemd is under the LGPLv2+, so we're license compatible. This code is probably pretty unintelligible unless you are familiar with the DBus type system. So I added some API docs trying to explain how to use them, as well as test cases to validate that I didn't screw up the adaptation from the original systemd code. Signed-off-by: Daniel P.
