~Would udev or dbus be preferred? It seems to me that dbus is the choice for desktop applications.~
It seems that there is an somewhat well-documented way to attach yubiguard to the dbus event loop, so it can list devices and get notified of new devices being added/removed.
The blog post at https://linuxmeerkat.wordpress.com/2014/11/12/python-detection-of-usb-storage-device/ summarizes benefits of the various abstraction layers, then comes to the conclusion that dbus is the right layer and then has example code (do an in-page search for the term "DBusGMainLoop" to find the relevant snippet).
@mozfreddyb Thanks for link. I am going to study it. However I do not know when I will have the time to make such big refactoring.
Thank you for responding so quickly. To be clear, I did not expect you to do this a) soon or b) all by yourself. Just wanted to get some clarity about a potential way forward. Maybe I'll be able to find time for some minor patches in that direction
The current method for detecting
YubiKeys
is extremely inelegant and causes high CPU load, as described under: #13Currently the slot occupation is polled periodically. A better approach would be to listen to events thrown by the system.
A fellow developer suggested to have a look into
udev rules
anddbus events
as a potential starting point for implementing such event based approach.Potentially this might also solve: #2
However, implementing such appproahc is currently beyond my understanding of OSes. Hence, such improvement would require help of other contributors more versed in that matters than I am are.
