From ef5e706ee19cf8024e0f2c9b1828c697bf62af26 Mon Sep 17 00:00:00 2001 From: openhands Date: Fri, 31 Jul 2026 15:01:34 +0200 Subject: [PATCH] perf: optimize DB layer with caching and pool tuning MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Add Redis cache wrapper (cached-db.ts) — cachedQuery + invalidate helpers - Add cached login user lookup (auth.ts: getLoginUser) — short 15s TTL for brute-force protection, cache invalidation on password/rank changes - Switch auth.ts login flow from Prisma facade to raw SQL via db.execute (avoids abstraction overhead for this hot path) - Cache invalidation wired in: login password upgrade, updateUser, resetPassword - Connection pool tuning: enableKeepAlive, namedPlaceholders, prepared statement cache (Node 22+), multipleStatements off (SQLi hardening) - 0 tsc errors, 583 tests passing --- src/actions/users.ts | 3 ++ src/lib/auth.ts | 85 ++++++++++++++++++++++++++++++++++++++++++-- src/lib/cached-db.ts | 56 +++++++++++++++++++++++++++++ src/lib/db.ts | 12 +++++-- 4 files changed, 152 insertions(+), 4 deletions(-) create mode 100644 src/lib/cached-db.ts diff --git a/src/actions/users.ts b/src/actions/users.ts index 063eeba3a0..b7210f2203 100644 --- a/src/actions/users.ts +++ b/src/actions/users.ts @@ -3,6 +3,7 @@ import crypto from "node:crypto"; import { z } from "zod"; import { hashPassword } from "@/lib/auth/password"; +import { invalidateLoginCache } from "@/lib/auth"; import { PERMS } from "@/lib/permissions"; import { prisma } from "@/lib/prisma"; import { adminAction } from "@/lib/safe-action"; @@ -119,6 +120,7 @@ export const updateUser = adminAction( } await prisma.user.update({ where: { id }, data: userData }); + invalidateLoginCache(targetUser.username); if (diamonds !== undefined) { await prisma.usersCurrency.upsert({ @@ -313,6 +315,7 @@ export const resetPassword = adminAction( where: { id: ctx.data.userId }, data: { password: hashed }, }); + invalidateLoginCache(target.username); logAudit({ userId: ctx.session.user.id, diff --git a/src/lib/auth.ts b/src/lib/auth.ts index e93aa3658a..0184dc10e8 100644 --- a/src/lib/auth.ts +++ b/src/lib/auth.ts @@ -1,15 +1,93 @@ import NextAuth from "next-auth"; import Credentials from "next-auth/providers/credentials"; +import { sql } from "drizzle-orm"; import { env } from "@/env"; import { getCachedJwtVersion } from "@/lib/auth/jwt-version-cache"; +import { cachedQuery } from "@/lib/cached-db"; +import { invalidateKey } from "@/lib/cached-db"; import { LaravelEncrypter } from "@/lib/auth/laravel-encrypter"; import { checkLogin } from "@/lib/auth/password"; import { verifyTotp } from "@/lib/auth/totp"; import { logger } from "@/lib/logger"; import { prisma } from "@/lib/prisma"; +import { db } from "@/lib/db"; import { clientIp, rateLimit } from "@/lib/rate-limit"; import { siteSettings } from "@/lib/services/site-settings"; +interface LoginUser { + id: number; + username: string; + password: string | null; + rank: number; + mail: string | null; + mailVerified: string | null; + twoFactorConfirmedAt: string | null; + twoFactorSecret: string | null; + accountBlocked: string | null; +} + +/** + * Cached login user lookup — short TTL to survive brute-force attempts + * while still reflecting recent password/account changes reasonably fast. + */ +async function getLoginUser(username: string): Promise { + return cachedQuery( + `login:user:${username}`, + async () => { + const [result] = await db.execute<{ + id: number; + username: string; + password: string | null; + rank: number; + mail: string | null; + mail_verified: string | null; + two_factor_confirmed_at: string | null; + two_factor_secret: string | null; + account_blocked: string | null; + }>(sql` + SELECT id, username, password, rank, mail, + mail_verified, + two_factor_confirmed_at, + two_factor_secret, + account_blocked + FROM users + WHERE username = ${username} + LIMIT 1 + `); + const rows = result as unknown as Array<{ + id: number; + username: string; + password: string | null; + rank: number; + mail: string | null; + mail_verified: string | null; + two_factor_confirmed_at: string | null; + two_factor_secret: string | null; + account_blocked: string | null; + }>; + return rows.length > 0 + ?
