fix: prevent duplicate ready events on SPA re-injection (#201653)
* fix: prevent duplicate ready events on SPA re-injection 1. Add _injectInProgress concurrency guard 2. Replace polling loops with waitForFunction 3. Deduplicate Backbone listeners via tuple array with cleanup 4. Atomic hasSynced check after listener registration 5. isMainFrame guard and storeAvailable SPA skip in framenavigated co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * fix: add robustness fixes from fork PR #41 - try/finally around inject() to always reset _injectInProgress - Atomic hasSynced check inside listener registration evaluate() - Fix framenavigated: capture isLogout before async, skip re-inject only when not logout AND store available - try/catch around obj.off() in listener cleanup - Null guard in QR ref change handler - Reset qrRetries on LOADING_SCREEN event - Add exposeFunctionIfAbsent in requestPairingCode() co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * fix: remove QR listener on auth success extract named onRefChange handler so it can be removed via socket.on('change:hasSynced') once authentication succeeds, matching PR #41's cleanup behavior. co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * refactor: remove exposeFunctionIfAbsent from requestPairingCode * fix: run refreshQR in browser context via pupPage.evaluate the onAuthAppStateChangedEvent callback is registered with exposefunctionifabsent, so it runs in Node.js context, not the browser. calling window.require() there throws ReferenceError: window is not defined, which means the QR code was never refreshed on UNPAIRED_IDLE state. * fix: remove unnecessary try/catch around Backbone .off() backbone's .off() never throws - verified on a live WhatsApp Web instance with non-existent listeners, fake events, and double-off. the try/catch was defensive but unnecessary. * fix: remove unnecessary try/catch blocks in framenavigated handler - storeAvailable: evaluate() always succeeds after framenavigated because Puppeteer waits for the execution context automatically (verified via CDP event order and Puppeteer source) - inject(): matches upstream behavior - let errors surface instead of silently swallowing them * fix: use AbortController to cancel inject on page navigation when WhatsApp Web does location.reload() during inject (e.g. after viewer context auth), puppeteer's waitForFunction hangs for 30s on a dead execution context. After the timeout, no recovery is possible. fix: - Replace _injectInProgress flag with AbortController pattern: new inject() calls automatically cancel any previous in-progress inject - Pass signal to waitForFunction for immediate cancellation - Move framenavigated handler registration before first inject() in initialize(), so navigation during startup triggers re-inject - Abort inject on destroy() to prevent spurious errors * chore: ignore *.d.ts in eslint upstream added TypeScript declaration changes that ESLint cannot parse. * chore: revert index.d.ts and .eslintignore changes * fix: reset _framenavigatedRegistered flag on destroy * fix: revert unintended setCurrentIndexHtml refactor from lint auto-fix * fix: replace async listener with waitForResponse for index cache the response listener used an async handler on EventEmitter. mitt ignores returned Promises, so when res.text() rejected on CDP disconnect the promise was orphaned - causing unhandledRejection. replace with page.waitForResponse() which returns a proper Promise chain. Use .catch((_) => _) following the existing convention in this codebase (see waitForNavigation on line 386). * Revert "fix: replace async listener with waitForResponse for index cache" This reverts commit 8cfd915ee5331d8b828c74ca8306dc72517bb0f1. --------- Co-authored-by: Claude Opus 4.6 <noreply@anthropic.com>
