From bda31a33bdf434f81c370c45532ea37cace9a254 Mon Sep 17 00:00:00 2001 From: Lucas Berger Date: Sun, 14 Jun 2026 22:56:18 -0400 Subject: [PATCH] fix(18): make timezone seed idempotent under concurrent race (WR-02) - Import sql from drizzle-orm in admin.ts - Add onDuplicateKeyUpdate({ set: { value: sql\`value\` } }) to the conditional INSERT in POST /config/timezone/seed so a concurrent seed (or seed racing a PUT) cannot 500 on the app_config.key PK constraint - Existing value is preserved per D-03 no-overwrite (no-op ODKU) - seeded flag still reflects the pre-flight SELECT (winner: true, loser: false) - Add tests: 403 access control, seeded:true on first seed, seeded:false on second seed without throw (WR-02 idempotent race) --- apps/api/src/routes/admin.ts | 13 +++++- apps/api/tests/routes/admin.test.ts | 63 ++++++++++++++++++++++++++++- 2 files changed, 73 insertions(+), 3 deletions(-) diff --git a/apps/api/src/routes/admin.ts b/apps/api/src/routes/admin.ts index 797f131..de49ceb 100644 --- a/apps/api/src/routes/admin.ts +++ b/apps/api/src/routes/admin.ts @@ -23,7 +23,7 @@ import { Hono } from 'hono'; import type { Context } from 'hono'; import { zValidator } from '@hono/zod-validator'; import { z } from 'zod'; -import { eq } from 'drizzle-orm'; +import { eq, sql } from 'drizzle-orm'; import { db } from '../db/client.js'; import { users, memberCredentials, calendars, appConfig } from '../db/schema.js'; import { requireAdmin } from '../lib/requireAdmin.js'; @@ -255,10 +255,19 @@ adminRouter.post('/config/timezone/seed', zValidator('json', timezoneSchema), as .limit(1); const alreadySet = existing?.value != null; + + // WR-02: Use onDuplicateKeyUpdate with a no-op (`set: { value: sql`value` }`) + // so a concurrent seed or a seed racing a PUT cannot 500 on the PK constraint. + // The no-op preserves the existing value (D-03 no-overwrite).
