Why networkmanager.WatchState panics?
ubuntu,go,network-programming,dbus
I haven't used the package myself, but from inspecting the source code, it seems like you should call endp.Dial before networkmanager.New because otherwise, endpoint.proxy stays uninitialised. endp := bus.SystemBus.Endpoint(networkmanager.BusAddress, lg) err := endp.Dial() if err != nil{ log.Printf("dial error %v", err) return } defer endp.Close() nm := networkmanager.New(endp, lg) ...
What's the meaning of this C++ syntax [duplicate]
It is a lambda function that: captures any used variables by reference [&] takes an argument (DBus::Connection&) does some work {...} To break down that line: auto path_dbus = [&] (DBus::Connection &bus) {... }; ^capture ^arguments ^work ...
“No D-BUS daemon running” when running phpunit test
php,firefox,selenium,functional-testing,dbus
As it turns out, the issues has to do with tmux not updating environment variables (not that it can). They manifest itself after restarting windows manager (exiting and starting it again) and leaving tmux running. As a result, DBUS_SESSION_BUS_ADDRESS changes its value, but processes running inside tmux has still the...
Bash store dbus output in array
You've modified IFS so the shell is splitting on . instead of whitespace. Don't do that. read is special in that it can take a "local" value for IFS directly. So instead of IFS=. while read ....; do ... done which modifies IFS for the entire shell you can do...
How to scan for bluetooth LE devices via dbus API?
ubuntu,bluetooth-lowenergy,dbus,bluez
You need to register for DBUS creations of org.bluez.Device1 proxy objects. The org.bluez.Adapter1 interface can then be used to StartDiscovery. This will scan for both Classic and LE devices. When a device is detected a Device1 object will be created and your registered callback will be invoked.
Registering an Object on DBus using pythons Gio-Bindings
This certainly not what you'll want to hear, but you have hit a 4 year old bug in the GDBus Python bindings that makes it impossible to register objects on the bus. A patch had been proposed quite some time ago, but every time it looked like it was actually...
How to continuously monitor rhythmbox for track change using python revisited
This works with Rhythmbox 3. I changed it to write the current song to a file ( ~/.now_playing ) but you can update it for your needs: #!/usr/bin/python import dbus import dbus.mainloop.glib import glib # This gets called whenever Rhythmbox sends the playingUriChanged signal def playing_song_changed (Player,two,three): global iface global...
How to re-init dbus SessionBus
Okay, a workaround is to directly connect to the SessionBus socket. bus = dbus.bus.BusConnection(os.environ['DBUS_SESSION_BUS_ADDRESS']) (I used this before but due to other problems I thought this wasn't working)...
DBus introspection object tree using dbus-send
No, this is not possible. You can ask bus to list all service names, but there is no way to ask all interfaces, so usually there are two scenarios: 1) You know interface names and use them 2) you start with / and process recursively based on Introspect() responses. D-feet...
using org.mpris.mediaplayer2.player PlaybackStatus property in python
python,string,media-player,dbus
You have to call the Get method to get the property. The method returns a string. I did the following to get playback status of VLC player: import dbus bus = dbus.SessionBus() vlc_media_player_obj = bus.get_object("org.mpris.MediaPlayer2.vlc", "/org/mpris/MediaPlayer2") props_iface = dbus.Interface(vlc_media_player_obj, 'org.freedesktop.DBus.Properties') pb_stat = props_iface.Get('org.mpris.MediaPlayer2.Player', 'PlaybackStatus') In my case (and hopefully in...
Skype returning empty CHATMESSAGES results through the DBus API
Skype will not use Invoke's return value when its reply is too heavy. As it so happens, when Skype has too much data to prepare and transfer after a request, it automatically returns an empty string to the Invoke call. The true, heavy reply is then prepared asynchrously by Skype,...
D-Bus method GetAll not found?
Signal 'PropertiesChanged' is sent also when a connection is deactivated. Then the object path for the "deactivated" connection does not exist anymore. That's why you are receiving the UnknownMethod exception. Before getting properties of the ActiveConnection make sure it still exists. Try the changes below: # Get ActiveConnection upon receiving...
GLib-GIO-CRITICAL error While invoking a method on dbus interface
The error tells you pretty clearly what the problem is. The "parameter" argument to call_sync (g_dbus_connection_call_sync in the C API) needs to be a tuple. You have provided a dictionary. Change k2 so that it is a tuple variant.
C++: How do I load a PulseAudio module via DBUS API?
c++,dictionary,dbus,pulseaudio
As my update said, a dict entry has to be in an array, but it doesn't have to be the only element in the array. For instance, PulseAudio's loopback module takes command line arguments like this: $pactl load-module module-loopback source="alsa_input.pci-0000_00_1b.0.analog-stereo" sink="bluez_sink.10_B7_F6_02_1B_4A" In order to send this over DBUS, the loadModule()...
How to safely use g_variant_iter_loop with data received via DBUS
When only one element is expected, is better to use if(iter != NULL) { g_variant_iter_next (iterator, "u", &value); } ...
How to add objects to DBus service from another process / program
you can't, one connection to dbus == one name. Connections are usually unix sockets or abstract sockets (on linux). You'll need to proxy calls from first connection using some kind or RPC ( or dbus call ) to other services and respond back results from first connection as well.
libdbus reading array type result
For array of not fixed size elements(such as strings), we must call dbus_message_iter_recurse(&args, &string);, giving pointer to main iterator as args and pointer for new iterator as second argument. To obtain element, we call dus_message_iter_get_basic(&string, &paths);, where paths is pointer to character array. The whole code looks like below: if...
which process is sending SIGKILL
linux,crash,signals,dbus,sigkill
I solved my problem. Although, I am not an expert on the subject, here is how I solved & which given me the conclusion of what was happening. First the solution, then we'll try to reason. Check whether system bus is up or not: while(conn==NULL) { dbus_bus_get(DBUS_BUS_SYSTEM,&err); if(dbus_error_is_set(&err)){ usleep(1000*50); }...
System dbus does not allow punching out ownership with conf files
linux,configuration,dbus,qtdbus
I finally found the issue. When Dbus looks for configuration files for punching out permissions (like ownerships) the file not only must be in system.d/ but it must also end in .conf. My configuration file "org.dbus.arduino" should have been "org.dbus.arduino.conf". I removed the code from system.conf. Confirmed I no longer...
dbus c program - send(with reply) and receive using method_call
Have a look here: http://www.freedesktop.org/wiki/IntroductionToDBus/ From what it looks like you need to write a file "*.service" that describes the service. (Quoted from the website) # (Lines starting with hash marks are comments) # Fixed section header (do not change): [D-BUS Service] Names=com.bigmoneybank.Deposits;com.bigmoneybank.Withdrawals Exec=/usr/local/bin/bankcounter This is what I found within...
Cannot disable systemd service
Try the systemd mask command rather than disable: systemctl mask <service_name> The disable command still allows the service to be started, for example, in response to another service requesting it as a dependency (even if optional), or manually. However mask disables the service completely. Also, I don't believe either mask...
Suspend script doesn't pause media players
linux,bash,media-player,sleep,dbus
I was finally able to do it. But I had to use setuid extensively, which I don't think is very secure. Anyway, here's the finished script: #!/bin/bash # Function for pausing the audio of each MPRIS-enabled media player. pause_music() { # This has to get the current address for the...
How is the “car.xml” file from dbus example called “D-Bus remote controlled car example” generated?
I have figured it out myself. The tool namely qdbuscpp2xml, does not assign a name attribute to the <node> as of now. If one wishes to assign a name attribute to it, she has to type it in by herself but for the <interface> node, it's possible to have the...
