#!/usr/bin/env bash
# =============================================================================
# start-relay-for-tests.sh — Start the Buzz relay and its backing services
# =============================================================================
# Shared script for CI jobs that need a running relay. Starts docker compose
# services, waits for health, applies the schema, builds the relay, starts it,
# and polls readiness.
#
# Usage:
#   ./scripts/start-relay-for-tests.sh [--profile <cargo-profile>] [--no-build]
#
# Options:
#   --profile <profile>   Cargo build profile (default: ci)
#   --no-build            Use existing target/<profile>/ binaries (CI artifact reuse)
#
# Exports:
#   RELAY_URL=ws://localhost:3000
# =============================================================================

# non-default ports, so the host must be 'localhost:3000' verbatim to match
# RELAY_URL=ws://localhost:3000. The relay never auto-seeds a community
# (ensure_configured_community has no callers) and fails closed on an unmapped
# host, so without this row every e2e connection would 404 at host-binding.
# The unique index is on lower(host), so ON CONFLICT must target that expression.
# psql is not on PATH in the hermit env; postgres runs as the buzz-postgres
# docker container, so exec into it (same fallback as setup-desktop-test-data.sh).
