# Full ceph/s3-tests sweep against RustFS.
#
# The per-PR compatibility gate lives in ci.yml (job s3-implemented-tests) and
# runs only the implemented_tests.txt whitelist. This workflow complements it:
#
#   - Scheduled weekly full sweep (TEST_SCOPE=all): runs the ENTIRE upstream
#     suite and reports promotion candidates (tests that newly pass) and
#     unclassified tests. The job fails only on regressions in the implemented
#     whitelist or on infrastructure errors — expected failures from
#     not-yet-implemented features do not turn the run red.
#   - Manual runs (workflow_dispatch): same, with configurable mode/scope.
#
# All test execution is delegated to scripts/s3-tests/run.sh (single source of
# truth, also used locally and by the PR gate). This workflow only provisions
# the server topology: a single node, or a real 4-node distributed cluster
# (erasure-coded across nodes) behind an HAProxy round-robin load balancer.
#
# Runner infrastructure (ci-1, backlog#1149): this sweep needs BOTH a working
# Docker daemon (to build the source image and run the single/multi topologies)
# AND a Python toolchain with pip (for awscurl/tox and the pytest harness).
# It previously ran on the self-hosted `sm-standard-4` label, which is served
# by heterogeneous runners: some scheduled runs landed on minimal pods that
# had neither `pip` (bare python3, `No module named pip`) nor `docker.sock`,
# so "Install Python tools" died before any test executed (all 15 recorded
# runs failed). Two changes make the infra assumptions explicit instead of
# trusting drifting runner state:
#   1. Pin to GitHub-hosted `ubuntu-latest`, which reliably ships Docker,
#      docker compose, python3 and pip (no self-hosted fleet drift).
#   2. Set up Python explicitly (actions/setup-python) before any pip usage,
#      so the workflow stays correct even if the runner image changes.
# The PR gate (ci.yml s3-implemented-tests) is unaffected: it avoids Docker
# via DEPLOY_MODE=binary and defers all pip setup to run.sh's self-bootstrap.
