On Linux, loader.sh can't install the default latest Aurora DSQL Loader, or any release from v2.0.2 on. It prints "Fetching release information from GitHub..." and exits 1 without saying why, so a load on a Linux machine that doesn't have the loader yet stops there too. macOS works.

No existing issue. I found this while reading the script. The Linux assets switched to musl in aurora-dsql-loader v2.0.2.

Changes

• detect_platform asked for <arch>-unknown-linux-gnu assets, but every aws-samples/aurora-dsql-loader release from v2.0.2 (2026-02-20) through v3.3.0 publishes its Linux builds only as aurora-dsql-loader-{x86_64,aarch64}-unknown-linux-musl.tar.gz. Linux now looks for the musl asset first and falls back to gnu, so a --version v2.0.0 or v2.0.1 pin (the only gnu releases) still installs.
• When no asset matched, grep exited 1 inside the download_url=$(...) assignment and set -euo pipefail ended the script before the existing "Could not find download URL for platform" check could run. The assignment now ends with || true, so that message prints.
• Bumped databases-on-aws to 1.10.1 in the marketplace and both plugin manifests, as fix(databases-on-aws): block psql meta-commands in psql-connect.sh --command #232 did for its psql-connect.sh fix.
• Added tools/evals/databases-on-aws/dsql/scripts/test_loader_sh.py next to test_safe_query.py, and listed it in tools/evals/databases-on-aws/README.md. It runs loader.sh --install-only --version <tag> with stub uname and curl commands that serve a release's asset list and record which URL the script tries to download:
  • Linux x86_64 and aarch64 on v3.3.0 pick the musl tarball (fails on main, no download is attempted)
  • Linux x86_64 on v2.0.1 picks the gnu tarball (passes on main, and fails without the fallback)
  • macOS arm64 picks the darwin tarball (passes before and after)
  • a release without a Linux asset prints the error and exits 1 (fails on main, which exits 1 without the message)

Verification:

• uv run --with pytest pytest tools plugins: 137 passed
• bandit -r . -x ./.tmp,./node_modules: no issues
• semgrep scan --oss-only --config=tools/semgrep/rules-vendored.yaml: no new findings
• ruff check and ruff format --check (v0.15.0, as in pre-commit) on the new test, markdownlint-cli2 on the README, dprint check, the lint:manifests ajv checks on the three manifests, and node tools/validate-cross-refs.cjs: clean (the one cross-refs warning, about migration-to-aws, is on main too)
• Against the live GitHub API, with only uname stubbed as Linux x86_64, the patched script downloaded v3.3.0's aurora-dsql-loader-x86_64-unknown-linux-musl.tar.gz and installed it. file reports ELF 64-bit LSB pie executable, x86-64, ... static-pie linked.
