subiquity / curtin

  • fixed list of available third-party drivers incorrectly returned as empty while the list is still being fetched LP: #2023265
  • opened initial PR to list OEM meta-packages. More to come in the coming days.
  • discussed the ability for users to reuse a /boot partition without formatting. This caused the initramfs from other OSes to be regenerated by curtin => going forward, the installer will prevent such configuration
  • spec work for OEM / ubuntu-drivers

distro

  • working on merge for dbus

  • subiquity
    • PR: 1689 - add enough infrastructure to allow ZFS rootfs autoinstall.
    • PR: 1687 - fix a footgun where configuring cloud-config for the install session with no default user would crash subiquity. (Not a cloud-init bug)
    • File LP: #2022102 - autoinstall with Mantic by way of cloud-init is broken right now. Cloud-init to provide a more intentional location for apps like Subiquity to retrieve the merged cloud-config.
  • proposed-migration: dgit vs git (LP: #2022096) - Upload a patched dgit to disable some tests.

armhf time_t analysis

  • add parallelization of abi-compliance-checker calls (up to 2.5x speedup on CPU-intensive jobs)
  • add the ability to split packages; this is needed when there are incompatible or when a package is to big; if a sub-package exhibits ABI breaks other sub packages are skipped (this makes it possible to “finish” huge packages like libclang-1[45]-dev which cannot be analyzed in full)
  • fixed analysis of several packages

Misc

  • worked on the application of Foundations to bug control
  • more clean up of tickets on LP for openssl

autopkgtest

  • Reviewed an MP from @andersson123 which adds a --dry-run mode to seed-new-release as that is something that times out for us regularly when opening adding a new release to the autopkgtest environment.
  • Updated novarcs.tar (openstack / nova environment variable files) on wendigo for staging to include lcy02 and drop lcy01.
  • Setup lcy02 (PS5) amd64 test runners in the staging prod-proposed-migration environment, so that staging and production are the same.
  • Submitted an MP about autopkgtest-cloud and OpenStack rc files.
  • Submitted an MP regarding updating the “Supply secrets” portion of the documentation for mojo and juju.
  • Reported a bug regarding expanding the number of people who can retry autopkgtests.
  • Submitted a canonical-is-firewall MP updating the IP address range for the PS5 staging network.
  • Wrestled with the PS45 and PS5 openstack networks having different names and was able to sort it out with some help fr
    om @cjwatson. Submitted an MP updating the service-bundle to use the new network name.
  • Reported a bug regarding the autopkgtest-cloud-worker charm and when it doesn’t update some config files.
  • Worked with @andersson123 to troubleshoot an issue with the autopkgtest-web server in staging.

Ubuntu

  • While performing an SRU review of glibc I discovered an inconsistency in our process and worked on sorting it out.
  • Submitted an MP for copy-package which makes it a bit more informative about where the package will be copied.

Misc

  • Short week due to being out for one day.
  • Reviewing candidate applications.

Distro

  • +1 maintenance week (report so far)

  • delve: FTBFS due to the installed bpftool not matching the running kernel version.
    I tried to workaround this by calling bpftool directly from /usr/lib/linux-tools-.
    It kinda worked but the build still fails for a different reason. See LP: #2021481

  • bpftrace: FTBFS on armhf. Fixed, see: LP: #2023173
    Also submitted to Debian #1037185

  • cbmc: FTBFS on all architectures.
    The compiler is catching some error I believe are false positives.
    The are some optional variables that it says are MAYBE uninitialized.
    I added -Wno-error=maybe-uninitialized to the CXX FLAGS.
    LP: #2023276

  • pistache: FTBFS on all architectures except riscv
    One of the unit tests tries to resolve an address and fails
    because the build doesn’t have access to the internet.
    It’s not failing on the Debian’s CI.
    A patch was submitted to the upstream project https://github.com/pistacheio/pistache/pull/1134
    LP: #2023274

  • ctffind: FTBFS on non-x86 architectures
    It’s using x86 assembly inline. I implemented an alternative code calling
    sinf() and cosf() from the libc instead.
    LP: #2023288
    Debian bug: #1037227

  • elinks: FTBFS on s390x
    A tool used during tests, sgml-parser, is crashing. There is a number
    of memory issues in the code that are not making it crash on other architectures.
    One can see them by using valgrind or compiling elinks with address sanitizer.
    See: LP: 2023305
    I also reported the problem upsteam: https://github.com/rkd77/elinks/issues/235

Netplan

  • Started investigating how to add support for veths
  • Investigated and fixed an issue related to keyfiles parsing and wireguard configuration (PR#366)

autopkgtest-cloud

  • Merged MP for script for updating all machines in juju environment when starting development for new release
  • Merged MP for packing charms on commit to check for breaking changes
  • Wrote scripts for testing various mirrors for each set of env variables in the cloudrc files in the autopkgtest-cloud environment - enabling us to use the fastest mirror for each env.
  • Worked on MP for seed-new-release script which runs with a --fake-release flag, for further testing addendum to the --dry-run flag. The aim is to troubleshoot issues with the script (right now, it requires being put into a while loop to run until it succeeds, due to flaky swift connection)

qa-jenkins-jobs

  • Wrote an MP for a daily charmcraft pack of the autopkgtest-cloud charms(@paride fixed some breaking issues in venonat to enable it to work)

Misc

  • Fixed janky lxd installation on venonat
  • Started work on an MP for LPCI which adds a command line flag to enable verbose output of git information in an lpci run
