# 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.
#
# `--sensitive-only` is deliberately NOT passed. That flag gates on the source
# classifier, which misses Rcpp: the repair therefore skipped Rcpp entirely,
# leaving its 4.5-built flat binary as the only copy and breaking every R 4.4
# client on the slot.
#
# Since bincraft v5.3.0 the destination is decided by the built binary's symbols
# in `upload_single_binary()`, so building unconditionally is safe: a package
# that needs a per-minor slot lands there, and one that does not lands in the
# flat slot. Skipping before the build is what removed that decision.
#
# 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.
