Sorry in advance for the lack of links; Discourse will not let me do more than two because “Sorry, new users can only put 2 links in a post.”

  • +1 maintenance last week

    • Still looking for sponsors on pytest-mock (LP: #1965442) and python-uvicorn (LP: #1965578)

    • @sylon sponsored all the uploads

The rustc MIR has seen some new developments:

  • Patched the second embedded copy of rust-crossbeam-utils 0.7.2 for the CVE-2020-15254 as it’s equally vulnerable, despite not having been yanked by upstream.
  • Demoted cargo from Recommends to Suggests in the rustc binary package to allow the latter to be promoted to main. Since this is not a bugfix and has some potential for breakage, it and the CVE patch are waiting for a FFe
  • Worked on figuring out a new source-level control header for packages that vendor sources, which will likely be the case for Rust packages in main in the near future.
  • Discussed another new field, this time for binaries, to keep track of statically linked dependencies in a given package (dependencies provided by separate packages at build time). Sadly no URL for that yet, except this dpkg patch


  • OpenSSL 3.0.2 has been uploaded, sponsored by @teward. It’s still stuck in -proposed at the moment, I haven’t had time to get to all the test failures yet.
  • Cherry-picked a patch from Debian for the tcltls FTBFS
  • Some generic triage on LP


PR reviews:


  • Reviewed a python-pecan patch for @enr0n (and uploaded it, not realizing it’s in main…)
  • Wrote an endorsement for @athos-ribeiro’ MOTU application.
