From a3f91450054e1183b04cb3e38cb118424ee75815 Mon Sep 17 00:00:00 2001 From: Claude Date: Wed, 4 Mar 2026 13:00:06 +0000 Subject: [PATCH 1/4] fix(telegramSafe): exempt getUpdates and lifecycle calls from 15s timeout MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Telegraf's long-polling uses getUpdates with timeout=50 (Telegram holds the connection for up to 50 seconds waiting for new updates). The callApi patch was wrapping ALL methods — including getUpdates — with globalThrottle, which has a hard 15-second race. This fired on every poll cycle, throwing 'rateLimiter: API call timed out after 15000ms', causing bot.launch() to reject and systemd to enter an infinite restart loop. Fix: add getUpdates (and Telegraf startup/lifecycle calls: getMe, deleteWebhook, setWebhook, getWebhookInfo, close, logOut) to the _MANAGED bypass set so they call the original callApi directly without the timeout wrapper. All 60 unit tests pass. Bot loads cleanly in CI mode. https://claude.ai/code/session_01WpEqAiDbpqnBywMjYXJHf4 --- telegramSafe.js | 15 +++++++++++++++ 1 file changed, 15 insertions(+) diff --git a/telegramSafe.js b/telegramSafe.js index 2d7aa45..4c58204 100644 --- a/telegramSafe.js +++ b/telegramSafe.js @@ -180,9 +180,24 @@ function init(bot) { // layer and pass through to the original. if (typeof tg.callApi === 'function') { const _MANAGED = new Set([ + // ── Individually-patched above — skip double-wrap ──────────────── 'sendMessage', 'editMessageText', 'answerCbQuery', 'answerCallbackQuery', 'sendPhoto', 'sendDocument', 'sendAnimation', 'sendSticker', 'forwardMessage', + // ── Long-poll — MUST bypass the 15-second API_CALL_TIMEOUT_MS ──── + // Telegraf passes timeout=50 to getUpdates so Telegram holds the + // connection open for up to 50 s.

The bot service runs as the 'runewager' system user but qa/ is owned by root, so writeFileSync was throwing EACCES on every startup, which was caught by startBot()'s outer try/catch and called process.exit(1). 2. telegramSafe.js — callApi bypass list refactored (code review feedback): The inline _MANAGED set is replaced with three named, exported constants: - LONG_POLL_METHODS : getUpdates (must bypass 15 s timeout) - LIFECYCLE_METHODS : getMe, deleteWebhook, setWebhook, etc. - INDIVIDUALLY_PATCHED_METHODS : sendMessage, sendPhoto, etc. Combined into CALLAPI_BYPASS_METHODS used by the callApi patch. All sets are exported so test suites can assert bypass membership without requiring a live Telegraf instance. All 60 unit tests pass.

This caused silent crashes under systemd while manual `node index.js` worked fine (no sandbox). Changes: - ProtectSystem=strict → full /usr, /boot, /etc stay read-only; /var (where the app lives) is fully writable. No more brittle per-directory ReadWritePaths maintenance. - ProtectHome=true → false Service runs as root; /root is root's home. Node/npm use /root for internal caches and temp files — blocking it caused subtle startup failures that only appeared under systemd sandboxing. - UMask=0077 → 0022 0077 (owner-only) made log files mode 600, unreadable by log-tailing utilities running as non-root. 0022 gives the standard 644/755. - ReadWritePaths kept as belt-and-suspenders documentation; functionally redundant under ProtectSystem=full but makes intent explicit and guards against future tightening. - Expanded inline comments explain each directive's rationale so the next operator understands the trade-off before changing settings.
