GLT 2025: systemd’s D-Bus Implementation, And Its Python asyncio Binding

• GLT 2025 Submission: systemd’s D-Bus Implementation, And Its Python asyncio Binding
  • Abstract
  • Description
• Talk Preparation: systemd’s D-Bus Implementation, And Its Python asyncio Binding
  • Slides: systemd’s D-Bus Implementation, And Its Python asyncio Binding
    • TL;DR
    • Show
    • A Big Picture
    • Sample Client (sdbus, Blocking)
    • Defining Interfaces, Pythonically
    • History/Implementations/Bindings ⟶ sdbus
    • Concrete Use Case: jf-irrigation
    • Irrigation Client: Enter asyncio
    • First Step: Create Proxy
    • Naive try: Use Async Definition To Block
    • Fix: Async Machinery
    • Create Irrigator Proxies
    • Print Statistics
    • D-Bus Signals
    • And Parallelism?
    • Introduce asyncio.TaskGroup
    • Keep In Mind …
    • More asyncio
  • Old Stuff, Random Notes
    • D-Bus Show
    • D-Bus Spec, Implementations
    • Client Implementation
    • Gotchas, Weirdnesses
  • What Else?
    • Irrigation Outlook

• D-Bus signals: errors (toplevel exception handling at server side - taskgroup?)
