From e5e80059902fa4fe0f8bd9826f6ade1030edd90d Mon Sep 17 00:00:00 2001 From: Roo Code Date: Wed, 10 Sep 2025 08:07:00 +0000 Subject: [PATCH] fix: Apply PR feedback for DismissibleUpsell component - Changed from className to separate 'id' and 'className' props for better semantics - Added i18n support for accessibility labels (aria-label and title) - Fixed memory leak by adding mounted flag to prevent state updates after unmount - Fixed race condition by sending dismiss message before hiding component - Fixed inefficient array operations in webviewMessageHandler - Added comprehensive test coverage for edge cases including: - Multiple rapid dismissals - Component unmounting during async operations - Invalid/malformed message handling - Proper message sending before unmount - Added null checks for message data to handle edge cases gracefully --- src/core/webview/webviewMessageHandler.ts | 30 +-- .../components/common/DismissibleUpsell.tsx | 46 +++-- .../__tests__/DismissibleUpsell.spec.tsx | 179 ++++++++++++++++-- 3 files changed, 211 insertions(+), 44 deletions(-) diff --git a/src/core/webview/webviewMessageHandler.ts b/src/core/webview/webviewMessageHandler.ts index 601c4e9b65..0a1597a32e 100644 --- a/src/core/webview/webviewMessageHandler.ts +++ b/src/core/webview/webviewMessageHandler.ts @@ -3000,20 +3000,26 @@ export const webviewMessageHandler = async ( } case "dismissUpsell": { if (message.upsellId) { - // Get current list of dismissed upsells - const dismissedUpsells = getGlobalState("dismissedUpsells") || [] + try { + // Get current list of dismissed upsells + const dismissedUpsells = getGlobalState("dismissedUpsells") || [] - // Add the new upsell ID if not already present - if (!dismissedUpsells.includes(message.upsellId)) { - const updatedList = [...dismissedUpsells, message.upsellId] - await updateGlobalState("dismissedUpsells", updatedList) + // Add the new upsell ID if not already present + let updatedList = dismissedUpsells + if (!dismissedUpsells.includes(message.upsellId)) { + updatedList = [...dismissedUpsells, message.upsellId] + await updateGlobalState("dismissedUpsells", updatedList) + } + + // Send updated list back to webview (use the already computed updatedList) + await provider.postMessageToWebview({ + type: "dismissedUpsells", + list: updatedList, + }) + } catch (error) { + // Fail silently as per Bruno's comment - it's OK to fail silently in this case + provider.log(`Failed to dismiss upsell: ${error instanceof Error ?
