Summary

  • detect when a historical conversation belongs to a different workspace before restoring it
  • offer to use the current workspace, open the original workspace in a new window, or cancel
  • persist the selected current workspace so file mentions, tools, commands, prompts, and workspace-scoped controllers use one consistent root
  • reset only that task’s incompatible checkpoint repository and remove stale checkpoint-only timeline rows when moving workspaces
  • apply the same policy to extension API task resumes while leaving internal checkpoint/delegation rehydration unchanged

Fixes #1602

Validation

  • targeted provider and file-search Vitest suites: 173 tests passed
  • focused workspace-selection tests: 6 passed
  • touched-file ESLint and Prettier checks passed
  • workspace lint: 11/11 packages passed
  • workspace/pre-push typecheck: 11/11 packages passed
  • task lifecycle model-check suite passed

Note

Validation ran successfully under Node 26.8.2; the repository declares Node 22.23.1.

2382-2383: 🗄️ Data Integrity & Integration

Keep backup cleanup out of the rollback transaction.

fs.rm(checkpointBackupDir, { recursive: true, force: true }) runs inside the transaction that restores messages and history. Recursive removal retries selected errors, but it is not transactional. (nodejs.org)

If deletion fails after removing some entries, the catch restores checkpoint_saved rows and renames the incomplete backup to checkpointsDir. A later resume can reference missing checkpoint data. Complete the message and history commit first. Run backup deletion afterward as best-effort cleanup and log failures.

📝 Summary

Summary by CodeRabbit

  • New Features

    • Added workspace-aware task resumption.
    • When a saved task belongs to a different workspace, you can continue in the current workspace or open the original workspace in a new window.
    • Continuing in the current workspace updates the task and resets workspace-specific checkpoints before resuming.
  • Bug Fixes

    • Tasks resume unchanged when their saved workspace matches the current workspace or is unavailable.
    • Cancelled workspace selections no longer restore the task.
    • Failed updates now restore the task’s previous checkpoint state.

Walkthrough

Historical task resumption now compares saved and current workspace paths. A workspace mismatch prompts the user to keep the original workspace, use the current workspace, or cancel. Using the current workspace resets saved checkpoints before restoration.

Workspace selection and restoration
src/core/webview/ClineProvider.ts, src/extension/api.ts, src/core/webview/__tests__/ClineProvider.history-workspace.spec.ts, src/extension/__tests__/api-resume-task.spec.ts
Historical tasks are prepared before restoration. Matching or unavailable workspace paths resume unchanged. A mismatch can open the original workspace, use the current workspace, or cancel.
Checkpoint reset and rollback
src/core/webview/ClineProvider.ts, src/core/webview/__tests__/ClineProvider.history-workspace.spec.ts
Using the current workspace removes checkpoint_saved messages and the task checkpoint directory. Persistence failures restore the messages, checkpoint directory, and previous workspace value.

Merge Risk: 🟡 Moderate · up to 0964f

Moving a conversation to the current workspace can corrupt or lose its checkpoint history when cleanup encounters an I/O failure; this should be fixed before merge.

Full details: Regression Evidence

Explanation

The PR adds focused tests for matching, mismatch selections, cancellation, checkpoint removal, and rollback. However, required regression evidence is incomplete. prepareHistoryItemForResume has an explicit unavailable-workspace fast path at src/core/webview/ClineProvider.ts:2320-2324. HistoryItem.workspace is optional (packages/types/src/history.ts:42), and getWorkspacePath() can return an empty path when no workspace is open (src/utils/path.ts:152-167). The provider tests cover only non-empty paths. The API test omits workspace but mocks prepareHistoryItemForResume to return undefined, so it does not exercise the actual unset behavior. The changed API.resumeTask success path at src/extension/api.ts:220-228 also lacks a positive test that creates the task with the prepared item and posts the chat action. Finally, the explicit ENOENT checkpoint-directory branch at ClineProvider.ts:2368-2375 is not covered because the file-system fixture always creates the directory.

Resolution

Add provider tests for an undefined current workspace and an undefined historyItem.workspace; verify that each returns the original item without prompting or mutating state. Add a provider test for a missing checkpoints directory and verify that message cleanup and history persistence still complete. Add an API.resumeTask success test that resolves a prepared history item, asserts createTaskWithHistoryItem receives that item, and asserts the webview action is posted.

Full details: Persistence Integrity

Explanation

The changed workspace-reset path has incomplete rollback. In ClineProvider.ts:2377-2395, the operation stages checkpoints, writes filtered ui_messages.json, persists the updated history_item.json, and then removes the backup. If a later step fails, the catch block awaits message restoration first. If that restoration fails, execution skips checkpoint restoration and history restoration. For example, after the new history is persisted, a cleanup I/O error followed by a failed rollback write can leave the task with workspace set to the current workspace, checkpoint rows removed, and the checkpoint repository still only in the staging directory. The method then rejects without an explicit recovery state. The changed persistence path can therefore leave related files inconsistent.

Resolution

Make rollback steps independent and best-effort. Preserve the original operation error while attempting message, checkpoint, and history restoration in separate try/catch blocks, and always attempt all restorations. If any restoration fails, retain the staged checkpoint data, record an explicit recovery marker, and surface an actionable recovery error. Add failure-injection tests for each commit step and each rollback step.

Full details: Lifecycle Resource Cleanup

Explanation

The new async resume path can create a task after its provider is disposed. showTaskWithId and API.resumeTask now await prepareHistoryItemForResume; the Use Current Workspace branch performs filesystem and history writes before returning. Neither the preparation method nor either caller checks _disposed after those awaits. If a tab/provider restart or disposal occurs after the user selects Use Current Workspace but before the reset finishes, showTaskWithId or resumeTask still calls createTaskWithHistoryItem. That method has no disposal guard and installs a new Task, task event listeners, and scheduled work on the disposed provider. TaskHistoryStore.dispose() also does not reject later upsert calls, so the post-disposal history update can schedule the provider's global-state write-through timer again.

Resolution

Cancel or invalidate pending resume operations during ClineProvider.dispose(). Pass an abort signal or generation token through prepareHistoryItemForResume and check it after the warning prompt, after checkpoint reset, and immediately before createTaskWithHistoryItem. Make the creation path reject when _disposed is true. Make TaskHistoryStore.upsert and the provider write-through callback reject or no-op after disposal. Add a test that starts a mismatched resume, disposes the provider while preparation is awaiting, then resolves the selection and verifies that no task, listener, scheduler work, history write, or timer is created.

Test cancellation at both workspace-resume entry points.

When prepareHistoryItemForResume returns undefined, neither entry point may restore or reveal the task. Add separate caller-level tests:

  • ClineProvider.showTaskWithId: assert that createTaskWithHistoryItem and the chatButtonClicked action are not called.
  • api.resumeTask: assert that createTaskWithHistoryItem is not called.

The existing helper tests cover preparation cancellation only. They do not exercise either caller's early-return behavior.

Node.js fsPromises.rm recursive partial deletion failure atomic guarantee official documentation

💡 Result:

<search_synthesis>
The Node.js fsPromises.rm method does not provide an atomic guarantee for recursive deletions [1][2][3]. Official Node.js documentation describes fsPromises.rm as being modeled on the standard POSIX rm utility, but it does not claim that the operation is atomic [1][4][3]. Because recursive deletion involves multiple filesystem operations—such as listing directory contents, unlinking individual files, and removing subdirectories—a failure mid-process will not automatically roll back previous deletions. In recursive mode, if an error is encountered (specifically EBUSY, EMFILE, ENFILE, ENOTEMPTY, or EPERM), Node.js will attempt to retry the operation based on the maxRetries and retryDelay options, but this mechanism is intended to handle transient resource busy errors rather than to ensure transaction-like atomicity [1][2][3]. If the operation fails after all retries are exhausted, the filesystem may be left in a partially deleted state [1][2][3]. Users requiring atomic file system operations should consider using external tools or patterns, as Node.js&#39;s built-in file system APIs do not support transactions or atomicity for multi-step operations like recursive directory removal [1][5][3].

Do not roll back when backup cleanup fails.

fs is imported from fs/promises, and fs.rm(checkpointBackupDir, { recursive: true, force: true }) is a multi-operation recursive deletion. If it fails after deleting some entries, the surrounding catch restores the messages and renames the incomplete backup to checkpointsDir. The restored checkpoint_saved messages can then reference missing checkpoint data.

Complete the message and history transaction before deleting the backup. Treat backup deletion as best-effort cleanup and log its failure.

Proposed fix
 		try {
 			if (messagesWithoutCheckpoints.length !== messages.length) {
 				await saveTaskMessages({ messages: messagesWithoutCheckpoints, taskId, globalStoragePath })
 			}
 			await this.updateTaskHistory(updatedHistoryItem)
-			if (checkpointDirectoryStaged) {
-				await fs.rm(checkpointBackupDir, { recursive: true, force: true })
-			}
 		} catch (error) {
 			if (messagesWithoutCheckpoints.length !== messages.length) {
 				await saveTaskMessages({ messages, taskId, globalStoragePath })
 			}
 			if (checkpointDirectoryStaged) {
 				await fs.rename(checkpointBackupDir, checkpointsDir)
 			}
 			if (this.taskHistoryStore.get(taskId)?.workspace === updatedHistoryItem.workspace) {
 				await this.updateTaskHistory(originalHistoryItem)
 			}
 			throw error
 		}

+					`Failed to remove checkpoint backup for ${taskId}: ${
+						error instanceof Error ? error.message : String(error)
