This approach avoids blocking and eliminates Time-of-Check to Time-of-Use (TOCTOU) race conditions. + +## 2024-05-24 - O(N*M) array searching inside batch processing loop +**Learning:** During streaming event processing (like `handleAgentEvents`), using reverse array searches inside a loop over a batch of elements causes O(N*M) algorithmic scaling, significantly degrading CPU performance and creating UI thread blocks as the length of the chat array grows. +**Action:** When mapping over streaming arrays, cache relevant target indices *before* the batch iteration loop, then maintain and update these indices manually throughout the loop for O(N+M) complexity. Also, manage multi-element states correctly (e.g. use a Queue for multiple pending `tool_call`s mapping to `tool_result`s). diff --git a/packages/desktop/src/renderer/App.tsx b/packages/desktop/src/renderer/App.tsx index c7b3de8..b8d8d24 100644 --- a/packages/desktop/src/renderer/App.tsx +++ b/packages/desktop/src/renderer/App.tsx @@ -78,20 +78,22 @@ export default function App() { setMessages((prev) => { const updated = [...prev]; - // Optimization: use reverse for loop to find items near the end instead of O(N) findIndex/reverse - const findLastAssistantStreaming = () => { - for (let i = updated.length - 1; i >= 0; i--) { - if (updated[i].role === 'assistant' && updated[i].isStreaming) return i; + // Cache target indices before loop to avoid O(N*M) inner loop scaling + let lastAssistantIndex = -1; + for (let i = updated.length - 1; i >= 0; i--) { + if (updated[i].role === 'assistant' && updated[i].isStreaming) { + lastAssistantIndex = i; + break; } - return -1; - }; + } - const findLastToolCall = () => { - for (let i = updated.length - 1; i >= 0; i--) { - if (updated[i].role === 'tool' && updated[i].toolName && !updated[i].toolOutput) return i; + // Use a stack for pending tool indices as there could be multiple tool calls in a single batch + const pendingToolIndices: number[] = []; + for (let i = 0; i < updated.length; i++) { + if (updated[i].role === 'tool' && updated[i].toolName && !updated[i].toolOutput) { + pendingToolIndices.push(i); } - return -1; - }; + } for (const event of batch) { const d = event.data as any; @@ -99,38 +101,50 @@ export default function App() { case 'stream_text': { const text = d?.text ??
