From 75406a7d9b4866f393096cae38960fb85a720c9f Mon Sep 17 00:00:00 2001 From: Roo Code Date: Fri, 18 Jul 2025 15:20:47 +0000 Subject: [PATCH] fix: implement comprehensive gray state recovery for subtask completion failures - Add error recovery in Task.resumePausedTask() to handle provider disconnections gracefully - Enhance Task.recursivelyMakeClineRequests() with recovery mechanisms for API failures - Add ClineProvider.recoverFromGrayState() method with multiple recovery strategies - Enhance ClineProvider.finishSubTask() with comprehensive error handling - Add UI state validation in ChatView.tsx to detect and recover from gray state - Include comprehensive test suite for gray state recovery mechanisms Fixes #5892: Gray state issue where Orchestrator subtask completion with provider disconnection leaves parent task unusable --- src/core/task/Task.ts | 27 +- src/core/webview/ClineProvider.ts | 58 +++- src/tests/grayStateRecovery.test.ts | 334 ++++++++++++++++++++ webview-ui/src/components/chat/ChatView.tsx | 24 ++ 4 files changed, 436 insertions(+), 7 deletions(-) create mode 100644 src/tests/grayStateRecovery.test.ts diff --git a/src/core/task/Task.ts b/src/core/task/Task.ts index 53b8ef5b87..770107b204 100644 --- a/src/core/task/Task.ts +++ b/src/core/task/Task.ts @@ -780,7 +780,16 @@ export class Task extends EventEmitter { .deref() ?.log(`Error failed to add reply from subtask into conversation of parent task, error: ${error}`) - throw error + // Don't throw the error - instead try to recover gracefully + // This prevents the task from getting stuck in a gray state + console.warn(`[Task.resumePausedTask] Recovered from error during subtask completion: ${error}`) + + // Ensure the task can continue by adding a fallback message + try { + await this.say("subtask_result", `Subtask completed with recovery: ${lastMessage}`) + } catch (fallbackError) { + console.error(`[Task.resumePausedTask] Failed to add fallback message: ${fallbackError}`) + } } } @@ -1457,7 +1466,19 @@ export class Task extends EventEmitter { const history = await provider?.getTaskWithId(this.taskId) if (history) { - await provider?.initClineWithHistoryItem(history.historyItem) + try { + await provider?.initClineWithHistoryItem(history.historyItem) + } catch (recoveryError) { + // If recovery fails, ensure we don't leave the task in a gray state + console.error(`[Task.recursivelyMakeClineRequests] Recovery failed: ${recoveryError}`) + + // Force a clean state by clearing the task if recovery fails + try { + await provider?.clearTask() + } catch (clearError) { + console.error(`[Task.recursivelyMakeClineRequests] Failed to clear task during recovery: ${clearError}`) + } + } } } } finally { @@ -1731,7 +1752,7 @@ export class Task extends EventEmitter { const contextWindow = modelInfo.contextWindow const currentProfileId = - state?.listApiConfigMeta.find((profile) => profile.name === state?.currentApiConfigName)?.id ?? + state?.listApiConfigMeta.find((profile: any) => profile.name === state?.currentApiConfigName)?.id ??
