From 026437035d8f1d5a318c8f8d6ee67f03e20dfde9 Mon Sep 17 00:00:00 2001 From: Hermes Date: Wed, 7 Oct 2026 08:31:14 -0700 Subject: [PATCH] [pending-judge] fix(r5): exercise the boot-timeout kill, total bridge-body handling, strict subdomain labels (judge r4 blockers) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - __tests__/e2e-node/composition-root.e2e.test.js: `boot()` takes {timeoutMs, code} and the timeout rejection carries the child it killed; a NEW test drives the real timeout against a child that never reports PORT/READY and asserts the OS-observed SIGKILL on that child (marker e2e-timeout-kill) — the r4 claim is now exercised. - routes/deploys.js: bridge() coerces any non-object JSON body (null/[]/string) into the same failure shape as a non-JSON body, so no `body.ok` deref can 500 or report a false success; the subdomain label regex rejects leading AND trailing hyphens. - __tests__/routes/deploys.catalog.r4.test.js: trailing-dash rejection case + three malformed-successful-body cases (clean 502, never 500). --- .../e2e-node/composition-root.e2e.test.js | 56 ++++++++++++++++--- .../routes/deploys.catalog.r4.test.js | 17 ++++++ dashcaddy-api/routes/deploys.js | 14 ++++- 3 files changed, 78 insertions(+), 9 deletions(-) diff --git a/dashcaddy-api/__tests__/e2e-node/composition-root.e2e.test.js b/dashcaddy-api/__tests__/e2e-node/composition-root.e2e.test.js index 7a45345..d335561 100644 --- a/dashcaddy-api/__tests__/e2e-node/composition-root.e2e.test.js +++ b/dashcaddy-api/__tests__/e2e-node/composition-root.e2e.test.js @@ -29,11 +29,10 @@ let child; let PORT; let JWT; -// Boot the REAL app via its REAL entry contract (createApp + listen).
