  • Doing +1 this week. So far my time has been spent on transitions. No-change rebuilds have resolved most of tinyxml2. ros-ros-comm is still outstanding and entangled in py3.12, I have a patch for that but no proper way to test it. hiredis is the next transition I’m looking at, with no-change rebuilds started. Build failures related to the hiredis no-change rebuild can be seen on my hiredis ppa. Thanks to @ginggs who helped point out an improvement in how I was generating no-change rebuilds (dch -R).
  • python3-launchpadlib (LP: #2050186) - There was a report in IRC with a build log showing a dependency problem. python-launchpadlib uploaded with an additional dependency declared on python3-six. Fix uploaded.
  • curtin - minor fixes then merge Merge into master : cryptoswap : lp:~dbungert/curtin : Git : Code : curtin
  • continued work on mini.iso

Netplan

  • Working on improvements for SR-IOV NICs and better handling of VF LAG activation for Mellanox NICs. (Pending PR)

The biggest part of my week has been a single bug investigation that has lead me down quite a few rabbit holes, including:

  • Pango sources
  • fontconfig sources
  • GObject and how to actually look inside one in GDB (couldn’t figure it out)
  • the Python API of GDB (doesn’t expose symbols per ELF object, sadly…)
  • ltrace (and why it’s actually useless in this case)
  • eBPF (with a bit of time I could write a ltrace-like tool that wouldn’t be limited to calls from the main binary! But that’s too much time)
  • LLDB API → That’s my next hope!

Of course while writing this status report I ran a build against the latest snapshot just to double-check, and naturally the FTBFS vanished.

Computers, what a great invention.
