Can I just say that the errors you get back from #systemd's #dbus API are inscrutable nonsense and that the logs are frequently equally as unhelpful even if you try to turn on debug mode?

I've read
so much of the systemd container code at this point. But, I did basically re-implement the systemd-nspawn CLI as a python library, so that's neat.

Any hints on this?

In a (shell) script, I want do listen for an USB-stick with a well-known label to be plugged in and then mount it at some defined place. This shall be done all as non-root user and without permanent changes to the system (e.g in /etc), since it's only used when developing.
Desktop envs are able to do this, but require user interaction.

I looked at #dbus but the solutions I found require writing a custom listener in python. And did not yet manage to mount.

@rust_discussions none of my systems has #sudo - and never had.
"Back in the days", I just used "su", nowadays most applications use #PolicyKit to get elevated privileges for a specific operation and in case I need a full shell, "machinectl shell .host" (aliased to "msh" here) provides a proper (not just subprocess-spawned) session incl. a DBus and systemd user-session.

#dbus spec reading can be fun at times. About DBus.GetAdtAuditSessionData it says:

"Returns auditing data used by Solaris ADT, in an unspecified binary format. If you know what this means, please contribute documentation via the D-Bus bug tracking system. This method is on the core DBus interface for historical reasons"

@aruiz @bcantrill time to contribute to the D-Bus spec? ;)

Didn't even occur to me at the time that that someone would be me. 😎

🔴 Today on #SystemCrafters Live, we'll learn the fundamental concepts of D-Bus and then explore the D-Bus user session on a live system using Emacs' built-in functions.

By the end, you'll know how to query for information and invoke methods via D-Bus services, giving you a whole new level of system interaction right from your favorite editor!

@nekothegamer Well it's not a bug at GNOME's side. It's something on the side of apps you use. Seems like some app is opening an #MPRIS interface on #DBus but it's not closing it when it is expected to close it. You may use some dbus inspector tool to check which of the app is doing that.

Regarding my goal to try to lock the screen when a smart card is removed, I'm hitting walls after walls. the latest one is with #Gnome JS and #DBUS. I think I found the signal that should be connected to, but nothing happens meaning it looks like it's not being properly bound to the signal. Any hints?

The author explains that DBus is used by notify-send to propagate a request to show a notification and a single daemon is used to transport the mechanism.

I find the D-Bus documentation so hard to understand for some reason. They keep talking about interfaces, objects, paths, services, addresses, bus names... It all didn't make sense at all and then some genius, GENIUS person put this in the tutorial and it all clicked. Just goes to show that one new view on something you don't understand can immediately clear things up.

#development #DBus #documentation

Big Conceptual Picture 

Pulling all these concepts together, to specify a particular method call on a particular object instance, a number of nested components have to be named:

Address -> [Bus Name] -> Path -> Interface -> Method 

The bus name is in brackets to indicate that it's optional ~ you only provide a name to route the method call to the right application when using the bus daemon. If you have a direct connection to another application, bus names aren't used; there's no bus daemon.

most likely this is my compete lack of crypto knowhow but I am having trouble understanding why DBUS_COOKIE_SHA1 is so complicated. 🤔

Shouldn't it just be:

Client: This is the user I want to authenticate as.
Server: sure, here is my cookie context and ID of the cookie I want you to read from that.
C: cool, here is the sha1 of the cookie.
S (after compares the sha1 it received to sha1 it calculated for the cookie): you cool. Carry on!

What's all this business with challenges and random values?

Whenever I see #softwareengineers #coding with their #laptops while commuting on the #SoundTransit express I say to myself "compiling #dbus" and then I laugh and I laugh... On the inside.

But really, you aren't writing and good code right now, my friend. Take this opportunity to play #pokemongo like everyone else.

only way to find out all the implicit assumptions in your D-Bus library about the bus behavior: you write your own bus.

@Edent do you have by chance any insight about the status of Navigator.share() on #Linux? I'd kinda expect this to be a job for #dbus but I've no idea where to even start looking and this sounds just like the kind of feature you might be interested in too 🤓

Меня тут посетила мысль, А есть ли что-то похоже на D-bus только не в рамках одной машины, а что б между разными устройствами в сети?

Что б, например, из какого-нибудь приложения для заметок на ПК, можно было послать сигнал на открытие конкретной главы конкретной PDFки на электронной книжке

@aral the fact, that "list-machines" provides output is most likely the inconsistency here, as machines are also global.
The difference between #systemd's "--system" and "--user" mode is, whether something is managed within a user's resources and/or session, like user units/services running within a user's login/desktop session.
This has nothing to do with a users permissions to control services in the system context, for which privileges are granted via #DBus through #PolicyKit

I love how #gtk 4.0 still uses #glib 2.0 which *still* hasn't fixed how:
* GValue can't hold a GString. All strings must be null terminated, with no way to ever specify a length.
* Hard coded to require a non-optimized poll() loop, preventing libuv integration
* GAsyncResult doesn't emit a signal
* #DBUS is stupid

Dont know why, but loging in to my user, with using dbus-broker as system and user dbus implementation is about 4s faster/shorter compared to default #dbus. 🤔​

Spend my evening having great dinner and than doing some crazy JS hacking to create a PoC for a #libravatar dbus service.

I would love to get some feedback from people who use/build software that hooks into dbus if it makes sense to rewrite the project in a proper language and improve the whole setup or not.

#mdbus2 is a #DBus management tool.

mdbus2 is a tool for interacting with D-Bus (Desktop Bus). D-Bus is a standardized interprocess bus that allows processes/services to communicate with each other. mdbus2 can list services, list objects of a service, and call methods of a service. mdbus2 also has a shell for interacting with D-Bus, as well as a listening mode for monitoring activity on a bus.

In January, I switched to #FreeBSD on my work laptop (#Thinkpad X240). And what can I say, it has been glorious.

It's a bit like #Archlinux with even better documentation, but no #systemd, #polkit, #consolekit, #dbus, #pulseaudio or all that other crap that makes life miserable under #Linux these days.

My stack is #i3wm with #Firefox as main browser, #mutt/#thunderbird for email, #urxvt with #fish as $SHELL and #mpv for music/media, all atop a fully #encrypted, native #zfs pool. What's yours?
