# Build quarry on a Linux host, with the zit it is meant to run against.
#
# Why a script and not a cross-compile: the DuckDB bindings ship a static
# C++ library per platform that links against the GNU C++ runtime, and a
# cross-link from macOS with zig's libc++ fails on missing std::string
# symbols (tried 2026-09-04). Building ON Linux is the honest path, and
# the golang image proves it works in a container before a VPS exists:
#
# docker run --rm -v "$PWD":/src -w /src golang:1.26 scripts/build-linux.sh
#
# zit is pinned to a RELEASE, not whatever is on PATH: 0001 §2 makes the
# zit CLI the entire store interface, so quarry's behaviour is zit's,
# and the two must not drift. The release tarballs are qualified per
# target (see zit's release-manifest.json) and checksummed.
#
# Inputs (environment):
# ZIT_VERSION zit release to install (default below)
# GITHUB_TOKEN read access to the private zit repository, for its release assets
# ZIT_RELEASE_DIR a directory holding the tarball and SHA256SUMS instead of a token
# VERSION stamp for `quarry version` (default: 0.1.0-beta+<checkout hash or "local">)
# PREFIX where binaries land (default: ./bin)
set -eu
# 0.3.15 for the file-history index. 0.3.14 introduced it and cut a
# PATH-filtered log on the SQLite mirror from 129s to ~1s, but recorded
# no coverage, so any commit invalidated it and the next query rebuilt
# from the first check-in -- on a repository under development that is
# the common case. 0.3.15 records how much of the log the index covers
# and resumes from there, which is what makes it worth building once.
# 0.3.28 for `config export` (the inverse of import, zit#210) and the
# stack form of `merge --probe` (zit#211), which the strata pre-flight
# asks once per stack.
