Hello hello,

Rust 1.83 → Noble Backport

Last week I got hung up on Lintian errors. I’ve since learned how to use Lintian better. At time of writing, all architectures have built on a PPA except for RISCV (which is always slow). As soon as RISCV finishes I should be able to submit the backport for approval.

Docs Focus Week

@rkratky has started a docs focus week internally where we create and clean up our developer-focusing documentation. Now that the Rustc 1.83 port is in a holding pattern I plan to synthesize and write up the things I learned, focusing on Lintian footguns.

Team Building

The Rust foundations team has been doing some team building, starting with sharing our favorite books, games, and movies.

The following covers the last 4 weeks, including partial holidays (summer hols childcare coverage), and last week:

Questing

  • Prepared and uploaded patches for the remaining bugs in the A/B boot facility on Pi:
  • Uploaded merge for u-boot-menu (LP: #2120467)
  • Filed bug for wifi issue in questing daily on Pi 3+, 4, and 5 (LP: #2121560)
  • Investigated report of oem-config failure in Edubuntu daily
    • Found oem-config either took a long time to start or required some intervention in plymouth (timing of pressing Esc and oem-config suddenly appearing?)
    • oem-config then ran successfully, but without any window decoration, background, or top-bar (failure of window manager?)
    • oem-config completed, system rebooted, all appeared normal, but definitely something going on with first-time config

Noble

  • ISO testing for the .3 release

General

  • Patch pilot shift on Monday 11th Aug
  • Patch pilot shift on Monday 1st Sept
  • Pi meetings
  • Take home tests

  • Fix FTBFS in luajit
  • Analyze build failure related to RISC-V having moved to the RVA23S64 ISA profile and GCC 15.2. There are rather few of them, e.g.
    • The simde-everywhere version packaged with upstream WebKit does not work correctly.
    • Building upstream WebKit resulted in a GCC internal error (LP: #2122013)
