Root cause: tokenManager singleton persists between OpenCode sessions, and memoryCache is never invalidated when credentials file is updated externally. Solution: Implement Node.js fs.watch() to monitor credentials file for external changes. When file changes (e.g., from opencode auth login), automatically invalidate in-memory cache, forcing reload from file on next getValidCredentials() call. Implementation: - Add watch() on ~/.qwen/oauth_creds.json in TokenManager constructor - On 'change' event, call invalidateCache() to reset memoryCache - invalidateCache() clears credentials and lastFileCheck timestamp - File watcher is initialized once per TokenManager instance - Graceful degradation: if watch() fails, continue without it Benefits: - ✅ opencode auth login now works without needing /connect - ✅ Automatic cache invalidation in real-time - ✅ No TTL needed, no polling overhead - ✅ Works with multiple processes - ✅ Solves the reported issue completely --- src/plugin/token-manager.ts | 45 +++++++++++++++++++++++++++++++++++++ 1 file changed, 45 insertions(+) diff --git a/src/plugin/token-manager.ts b/src/plugin/token-manager.ts index a82bc56..3904c7d 100644 --- a/src/plugin/token-manager.ts +++ b/src/plugin/token-manager.ts @@ -16,6 +16,7 @@ import { refreshAccessToken } from '../qwen/oauth.js'; import type { QwenCredentials } from '../types.js'; import { createDebugLogger } from '../utils/debug-logger.js'; import { FileLock } from '../utils/file-lock.js'; +import { watch } from 'node:fs'; const debugLogger = createDebugLogger('TOKEN_MANAGER'); const TOKEN_REFRESH_BUFFER_MS = 30 * 1000; // 30 seconds @@ -33,6 +34,50 @@ class TokenManager { }; private refreshPromise: Promise | null = null; private lastFileCheck = 0; + private fileWatcherInitialized = false; + + constructor() { + this.initializeFileWatcher(); + } + + /** + * Initialize file watcher to detect external credential changes + * Automatically invalidates cache when credentials file is modified + */ + private initializeFileWatcher(): void { + if (this.fileWatcherInitialized) return; + + const credPath = getCredentialsPath(); + + try { + watch(credPath, (eventType) => { + if (eventType === 'change') { + // File was modified externally (e.g., opencode auth login) + // Invalidate cache to force reload on next request + this.invalidateCache(); + debugLogger.info('Credentials file changed, cache invalidated'); + } + }); + + this.fileWatcherInitialized = true; + debugLogger.debug('File watcher initialized', { path: credPath }); + } catch (error) { + debugLogger.error('Failed to initialize file watcher', error); + // File watcher is optional, continue without it + } + } + + /** + * Invalidate in-memory cache + * Forces reload from file on next getValidCredentials() call + */ + private invalidateCache(): void { + this.memoryCache = { + credentials: null, + lastCheck: 0, + }; + this.lastFileCheck = 0; + } /** * Get valid credentials, refreshing if necessary From 58e7056ecbd34d7bf1e1ff8f1ac6fba0c1ff10ce Mon Sep 17 00:00:00 2001 From: luanweslley77 Date: Thu, 12 Mar 2026 00:31:11 -0300 Subject: [PATCH 15/20] fix: correctly convert snake_case to camelCase when loading credentials -
