The port-conflict guard added in the previous commit made the six existing
blue/green deployment simulation tests fail. assert_port_free() shells out to
ss, and the simulation harness stubs git, curl, docker, nginx, pnpm and node —
but not ss. Because the runner is self-hosted and the containers use
--net=host, the simulation saw the production CMS containers holding 3002 and
3003 and refused to start its own candidate.
The harness now stubs ss. It reports no listener for every scenario except
'port-taken', which reserves whichever port the script asks about, so the
simulation stays independent of the host it runs on.
Also switched the ss probe from `command -v ss` to `type ss`. The stub is a
shell function delivered through BASH_ENV; `command -v` happens to find it,
but `type` is the reliable test for "is this resolvable", and the two differ
across shells.
Added a regression test for the guard itself: with the candidate port already
occupied, the deploy must fail, must not have run `docker run`, and must leave
the nginx upstream untouched on the old port — no half-finished cutover.
Verified it fails when the assert_port_free call is removed.
Deploy simulation: 26 passed. Full unit suite: 3316 passed, 12 skipped.
pnpm db:migrate runs on the host and reads DATABASE_URL from the deploy
directory's .env. When that variable was missing the deploy had already
built an image and run the browser gate before pnpm db:migrate aborted on
an empty value, so a release was paid for in full and then thrown away.
Check for the variable right after the .env is copied, before the build,
and say plainly that the live release was not touched. The deploy test
fixture gains a DATABASE_URL so it mirrors a working deploy directory
instead of the broken one.
Drop the leftover Playwright browser install and e2e smoke test from the deployment script, and update the deployment contract tests to cover the verify-deployed-release smoke check instead.
