So I started a cmake port over there: https://github.com/choeger/dbus-python-cmake Currently it does only build &amp; test on linux. I'll get to build &amp; test on windows now. Installing should be trivial. For testing on windows I first need to either get a bash or to port the testsuite to cmake/pure python. Dunno how long this will take. Please let me know, what you think and feel free to merge if you think my work is useful. </pre> Christoph Höger 2012-05-24T11:37:41 http://comments.gmane.org/gmane.comp.freedesktop.dbus/14727 <pre>i am trying to compile vlc, everything from source, i need the dbus package, after i success install dbus-1.4.20, i reboot, the ubuntu crash, what shall i do please help_______________________________________________ dbus mailing list dbus-PD4FTy7X32lNgt0PjOBp9y5qC8QIuHrW&lt; at &gt;public.gmane.org http://lists.freedesktop.org/mailman/listinfo/dbus </pre> Lee Wei han 2012-05-22T17:04:50 http://comments.gmane.org/gmane.comp.freedesktop.dbus/14722 <pre>Hi All, I am using dbus-1.4.16 (glib binding is done using the library glib-2.30 ) in a multi-threaded environment, like a server(different process) runs in one end, and a client(different process) in one end, but if i run a client, calling a same synchronous function for multiple times using threads, i am getting error like "Error in called_function name, msg="GDBus.Error:org.freedesktop.DBus.Error.NoReply: Message did not receive a reply (timeout by message bus)". (process:2064): GLib-CRITICAL **: g_variant_get_fixed_array: assertion `g_variant_is_of_type (value, G_VARIANT_TYPE_ARRAY)' failed but if i call this function only once, i am gettin my output properly. so i have a doubt like, whether dbus allows simultaneous execution of synchronise functions ? or it is only serial execution. kindly help me.

I tried using dbus-c++, and integrated it with a external mainloop (boost::asio) which internally uses edge triggered epoll. But i found that some signal handlers are deferred, so watches are not always working. I am using the custom watch API from dbus-c++, which is essentially a thin wrapper around the DBusWatch API from libdbus. Looking at the code, libdbus does not seem to support edge triggered watches. Edge triggered support would essentially mean that libdbus must read()/write() from/to the fd until it returns EAGAIN. From what i see, the only limitation seems to come from the default value of the max_bytes_{read,written}_per_iteration variables. I think that setting them to an arbitrary high number should be enough to make libdbus work with edge triggered epoll. Am i correct ? And how could i change these variables ? The alternative would be to call the (wrapped) dbus_watch_handle() repeatedly until the fd is not readable/writable anymore, bu</pre> Nicolas Cavallari 2012-05-21T12:58:46 http://comments.gmane.org/gmane.comp.freedesktop.dbus/14719 <pre>Thanks for your reply.

I have some performance concerns about a dbus app I am working on. callgrind indicates that many posix mutex locks are being taken on the server side during message validation. These calls are in alloc_link (and the corresponding call to free_link). I did a temporary hack to these functions, making them use malloc and free instead. This caused the mutex locks to drop off the radar (hurrah!) but it also caused malloc to feature much higher in the costs (boo!). I know that the code is the way it is because originally the cost of lots of small allocates via direct calls to malloc was found to be expensive. Heap fragmentation springs to mind. This was solved using a memory pool which was later made thread-safe by adding the locks. So going back to direct malloc is only an experimental hack. I am not proposing that this is done officially. Indeed, my profile results demonstrate that the repeated allocates are an issue. But I have a few thoughts about</pre> Andrew Marlow 2012-05-03T13:21:17 http://comments.gmane.org/gmane.comp.freedesktop.dbus/14709 <pre>hello. I am trying to set up dbus activation for a service (running on system bus). The service file looks like this: [D-BUS Service] Name=... Exec=... User=root The Exec= line specifies a shell script, which basically read options from a config file, and then launch a daemon with these options as arguments. I found that if my script's hashbang is #!/bin/sh, dbus won't do activation. When I launch a client, it will attempt to activate the service, but then will show an error: ERROR: Failed to connect to XXXXX: org.freedesktop.DBus.Error.Spawn.ExecFailed: Cannot launch daemon, file not found or permissions invalid ERROR: Failed to connect to daemon (bus: 'system')! However if the hashbang is #!/usr/bin/env sh, activation works. Why does the hashbang make a difference?

For this to heppen we need to figure out what interfaces and commands should be included in the LSB. The target version for inclusion would be DBus 1.4 Taking a look at openSUSE 11.4 I found 333 interfaces marked as GLOBAL in the library. But I didn't find any documentation of the interfaces on the DBus site. I was probably looking the the wrong place, thus if someone can point me in the right direction, that would be great. Also, should all the 333 interfaces be in the LSB, and if not what would be the best candidates for LSB inclusion? On the DBus site I found the following commands documented: dbus-daemon, dbus-send, dbus-monitor, dbus-launch, and dbus-uuidgen on openSUSE the dbus-launch command does not exist. Is this also common on other distributions?

I was just reading Lennart's post here http://0pointer.de/blog/projects/cgroups-vs-cgroups.html where he mentions balancing mysql and httpd even though they are made up of different numbers of processes. Some docs here: http://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/6/html/Resource_Management_Guide/sec-cpu.html If you were to split the system into "dbus-daemon" and "everything else" and say that when both need CPU, the CPU should be divided equally between those two groups, I wonder if that would solve the scheduling problem. I don't know if it's possible.

I have 2 questions. 1) The get_all() function takes the interface_name as an input. But this input seems to be optional (at-least according to the qdbusviewer). According to the specification is it in fact true (for multiple interface usecase). 2) If the input is infact optional and If some of the properties are not always valid. In the situation can the get_all() just skip those properties? I tried this and maybe it's just my implementation but it crashed. Has anyone done something similar? I couldn't find any examples of multiple interface in a single object at all. PS: By valid I mean it is not always relevant. Example to clarify the doubt. //standard Interface each needs to implement Object 1-&gt; Object1.Dbus.Introspectable Object 1-&gt; Object1.Dbus.Properties //implementation specific interfaces.

I have compiled and installed blueman and pulseaudio on a linux slackware 13.37 system. In blueman, I can pair my bluetooth headset with the computer, and then connect to the AudioSink (A2DP) service.

I can't use the BT headset in mplayer either (with alsa as an output layer), because I get an error (bt_audio_service_open: connect() failed: Connection refused (111)) Is this a D-BUS error?

I saved its password and I can easily mount it by simply clicking on its label in Nautilus. I'd like to automatically get this HDD mounted upon logging into Gnome. I'm sure that it's possible somehow, either through D-Bus or by calling Nautilus with some arguments. D-Bus may be more beneficial because it wouldn't involve any windows popping up.
