From 2ef7cbb9b1434de32c20a276d47d75857a2f3c08 Mon Sep 17 00:00:00 2001 From: Michael Cramer Date: Fri, 22 May 2026 20:12:29 +0200 Subject: [PATCH] fix: catchup shows no codes after startup backfill Three bugs prevented /catchup from showing codes to newly registered users: 1. backfillHandler never persisted pending codes - incremented stats.pendingCodes counter but never called codeManager.addPendingCode(), so no codes were stored in the database for /catchup to find. 2. backfillHandler skipped all user redemptions - checked 'success' in userDetailsResponse which is never true for valid PlayerData responses (they have a 'details' property, not 'success'). Fixed by checking !playerData?.details instead. 3. codeManager was missing several methods used by production code and tests: normalizeCodeStatus, isCodeRedeemedByUser, getAllValidCodes, addNewPendingCodes, getRedeemedCodeCount, deleteUserRedeemedCodes, getRedeemedCodesByUsers, getServerCodeStats, getAggregateLoot (now backed by loot_totals table), and backfillLootTotals. Additional fixes in codeManager: - addRedeemedCode: normalize numeric status codes via /^\d+$/ guard, fix onConflictDoUpdate target to [code, discordId], propagate isPublic flag correctly, write loot aggregates to loot_totals on Success. - addPendingCode: add onConflictDoNothing() to make it idempotent. - getRedeemedCodeDetails: add optional offset parameter. - addNewPendingCodes: chunk inserts at 499 rows (2 params/row) to stay within SQLite 999-variable limit. - getRedeemedCodesFromList: chunk IN queries at 997 codes (+2 status params) to stay within SQLite 999-variable limit. - deleteUserRedeemedCodes: COUNT(*) + DELETE instead of RETURNING to avoid materialising a large deleted-row array. - getRedeemedCodesByUsers: chunk discordIds within per-query param budget. - getPublicUnexpiredCodes: deduplicate by code (keep latest per code). - getAllValidCodes: single SQL query using NOT IN subquery on expired set. - Export CHEST_TYPE_NAMES and LootSummary type (used by codes.ts/stats.ts). backfillHandler fixes: - Normalize instance_id with String(...).trim() before comparing to '0'. - Use inserted.length from addNewPendingCodes() for stats.pendingCodes so re-runs do not over-report codes as newly pending. - Validate instance_id is present and non-'0' before calling submitCode, matching the guard in autoRedeemer.ts. - Replace N+1 isCodeRedeemed/addPendingCode loop with a single getRedeemedCodesFromList query + bulk addNewPendingCodes insert. Adds end-to-end tests covering the startup-backfill -> setup -> catchup flow, including API failure fallback, duplicate backfill idempotency, invalid instance_id skip, SQLite chunking boundary paths, and getPublicUnexpiredCodes multi-user deduplication.
