# Rebuild specific packages into a per-R-minor slot.
#
# The per-minor scheme only ever covered packages that passed through the build
# pipeline after it existed. A package built into the flat slot before that, and
# never updated on CRAN since, is never reclassified and never gets a per-minor
# copy - so the union index serves its flat binary to every minor. When that
# binary references a symbol the client's R no longer exports, the install fails
# at dyn.load():
#
# base64enc.so: undefined symbol: SETLENGTH
#
# base64enc calls SETLENGTH, its flat binary was built under R 4.4.3, and R 4.6
# does not export SETLENGTH. There was no way to rebuild one package into one
# minor from CI, only `just rebuild` from a workstation with the S3 and Postgres
# credentials to hand. This adds that path.
#
# `build-one.R --sensitive-only` re-runs the ABI classifier per version, so a
# package that turns out not to be risky is skipped rather than written into the
# wrong slot.
#
# Trigger with the slot and an explicit package list:
#
# crow pipeline create devxy/build-cran-binaries \
# --var rebuild_abi_gap=ubuntu-2604-amd64 \
# --var ABI_PACKAGES="base64enc@0.1-6 lobstr@1.2.1" \
# --var ABI_R_MINOR=4.6
variables:
# A manual pipeline creation instantiates every file in .crow/, so the
# default must match no matrix row.
