After roughly a week or so of the baton being passed between folks on +1
maintenance rotation, as of today the perl/re2/gdal/gsl/hdf5/qt/pdl/etc
transition has finally completed, comprising 416 packages (out of a total of
467 packages which were candidates) that have migrated as a group to the
release pocket.
My work on this over the last two days largely consisted of:
- finagling autopkgtests to get them to pass with the correct triggers
- rebuilding packages for several of the ancilliary transitions that had
only been partially completed
- rolling back r-cran-lwgeom in the archive because the new upstream
version has regressed on s390x for reasons that are not altogether clear
(git bisect points at a commit consisting of a wholesale import of a new
vendored version of liblwgeom from postgis, and there my investigation
stopped)
- with my archive admin hat, removing a handful of riscv64 binaries from
the release pocket which had regressed in buildability in -proposed as
part of the transition
- continuing to investigate the riscv64 build failure of atlas-ecmwf
I've also rebuilt libguestfs for a libyara transition, which should allow
that autohint from
https://people.canonical.com/~ubuntu-archive/proposed-migration/update_output.txt
to also complete.
That finishes all of the non-rust-related transitions that the autohinter
knows about; on the next run of proposed-migration,
https://people.canonical.com/~ubuntu-archive/proposed-migration/update_output.txt
should be a bit shorter and people may want to investigate why individual
packages there are stalled (for example, I just noticed libx86emu is an
soname transition, so triggered a no-change rebuild of hwinfo for that).
Also, I'm attaching the script I use locally for driving no-change rebuilds
for library transitions; perhaps others will find this useful, and perhaps
this can be cleaned up enough to be committed somewhere.
Things to hand off:
- ntirpc has a library transition, but its sole reverse-dependency,
nfs-ganesha, FTBFS and needs investigation.
- golang-pretty-dev is dropped in -proposed, so packages need updating to
golang-github-kr-pretty-dev.
- nautilus-python has dropped python2 bindings, its revdeps need sorting
- there are plenty of rust packages stuck in -proposed. Unfortunately the
rust packages we sync from Debian are not generally in a consistent state
allowing migration (to Debian testing or to the Ubuntu release). If
someone takes a look at these, they will probably want to recommend
removals of various leaf packages blocking transitions.
