The Lite dev +# build already resolves the shared `nodedb-*` crates through cargo, and during +# internal development `.cargo/config.toml` patches `nodedb-types` to a local +# path inside the Origin repo. We ask cargo where `nodedb-types` actually +# resolves from (`cargo metadata`) and derive the Origin workspace root from its +# manifest path — a single source of truth, no duplicated path literal. +# +# Idempotent: `cargo build` rebuilds only when sources change. If `nodedb-types` +# resolves from the registry instead of a local path (i.e. nobody has the Origin +# source), we exit 0 WITHOUT exporting NODEDB_BIN, so the interop tests skip +# rather than fail — a Lite-only checkout still passes `cargo nextest run`. +# +# nextest runs this from the workspace root and reads exported env vars from the +# file named by $NEXTEST_ENV. + +set -uo pipefail + +if [ -z "${NEXTEST_ENV:-}" ]; then + echo "ensure-origin: \$NEXTEST_ENV unset — not running under nextest" >&2 + exit 1 +fi + +# Find where nodedb-types resolves on disk (its Cargo.toml manifest path). +types_manifest="$(cargo metadata --format-version 1 2>/dev/null \ + | grep -o '"manifest_path":"[^"]*/nodedb-types/Cargo.toml"' \ + | head -n1 \ + | sed 's/.*"manifest_path":"//; s/"$//')" + +if [ -z "$types_manifest" ] || [ ! -f "$types_manifest" ]; then + echo "ensure-origin: could not locate nodedb-types source; interop tests will skip" >&2 + exit 0 +fi + +# A registry checkout means the Origin source isn't available locally — skip. +case "$types_manifest" in + */registry/*|*/.cargo/*) + echo "ensure-origin: nodedb-types resolves from the registry (no local Origin source); interop tests will skip" >&2 + exit 0 + ;; +esac + +# Origin workspace root = parent of the nodedb-types crate dir. +origin_root="$(cd "$(dirname "$types_manifest")/.." 2>/dev/null && pwd)" +if [ -z "$origin_root" ] || [ ! -f "$origin_root/Cargo.toml" ] || [ ! -f "$origin_root/nodedb/Cargo.toml" ]; then + echo "ensure-origin: Origin workspace not found near $types_manifest; interop tests will skip" >&2 + exit 0 +fi + +echo "ensure-origin: building Origin binary (cargo build -p nodedb in $origin_root) ..." >&2 +if ! cargo build --manifest-path "$origin_root/Cargo.toml" -p nodedb --bin nodedb >&2; then + echo "ensure-origin: Origin build failed; interop tests will skip" >&2 + exit 0 +fi + +bin="$origin_root/target/debug/nodedb" +if [ ! -x "$bin" ]; then + echo "ensure-origin: built binary not found at $bin; interop tests will skip" >&2 + exit 0 +fi + +echo "NODEDB_BIN=$bin" >> "$NEXTEST_ENV" +echo "ensure-origin: NODEDB_BIN=$bin" >&2
