feat(web-shell): add /delete command with batch delete support by ytahdn · Pull Request #4603 · QwenLM/qwen-code

ytahdn · 2026-05-28T12:24:46Z

Summary

Add /delete slash command to web-shell for permanently deleting session data files
Add POST /sessions/delete batch endpoint to daemon server with proper error handling (only swallows SessionNotFoundError, surfaces InvalidClientIdError and other errors per-session)
Add deleteSessionsData() to SDK DaemonClient, unified single/batch delete to one endpoint
Add DeleteSessionDialog with multi-select support (Space to toggle, Enter to confirm), search/filter, and keyboard navigation
Distinguish errors vs notFound in single-delete action — throw on real errors, return false only for notFound
Surface failure reasons in batch delete UI — allFailed shows first error reason, partialFail includes error detail
Normalize Error objects to string messages in server JSON response
Add tests for server route (6 tests), SDK client (4 tests), and workspace provider (error-path test)

Test plan

npx vitest run src/serve/server.test.ts — 345 tests pass
npx vitest run test/unit/DaemonClient.test.ts — 137 tests pass
npx vitest run src/daemon/workspace/DaemonWorkspaceProvider.test.tsx — 9 tests pass

📋 Review Summary

This PR implements a comprehensive /delete command for web-shell with batch delete support, including a new server endpoint, SDK client integration, and a well-designed UI dialog with multi-select and search capabilities. The implementation is thorough with excellent test coverage and consistent error handling throughout the stack.

🔍 General Feedback

Strong test coverage: 6 tests for server routes, 4 for SDK client, and 3 for workspace provider actions — covers validation, success paths, and error scenarios
Consistent error handling pattern: Errors are normalized to strings at server boundary, per-session error tracking in batch operations
Good code reuse: Extracted formatRelativeTime utility to eliminate duplication across ResumeDialog, ReleaseSessionDialog, and DeleteSessionDialog
Thoughtful UX: Multi-select with keyboard navigation (Space/Enter/Esc), search/filter functionality, clear feedback for partial failures
Type safety: Well-typed response structures with removed, notFound, and errors arrays throughout the stack

🎯 Specific Feedback

🟡 High

packages/web-shell/client/components/dialogs/DeleteSessionDialog.tsx:88-93 — In batch delete partial failure handling, only the first error is shown to users. When deleting 10 sessions with 3 failures, users lose information about which specific sessions failed and why. Consider showing a detailed breakdown or list of failed sessions.
packages/cli/src/serve/server.ts:1675-1678 — The error normalization at the server boundary converts Error objects to strings, but the original error type information is lost. This makes it harder for clients to distinguish between different error types (e.g., permission errors vs. validation errors). Consider preserving error codes.
packages/webui/src/daemon/workspace/actions.ts:47-48 — Single session delete throws on any error, but batch delete returns errors silently. This inconsistency in error handling between deleteSession and deleteSessions may confuse callers. Consider making error handling consistent or documenting the difference.

🟢 Medium

packages/web-shell/client/components/dialogs/DeleteSessionDialog.tsx:105-110 — When all deletes fail, the message is set but selectedIds is cleared without user confirmation. Users might lose track of which sessions they attempted to delete. Consider preserving selection or offering retry.
packages/cli/src/serve/server.ts:1640-1641 — The validation check !sessionIds.every((id) => typeof id === 'string') could be more defensive by filtering out non-string IDs rather than rejecting the entire request. This would be more resilient to client bugs.
packages/web-shell/client/utils/formatRelativeTime.ts:6 — The function always uses Date.now() which makes it hard to test and could cause hydration mismatches in SSR scenarios. Consider accepting an optional now parameter for testability.
packages/web-shell/client/components/dialogs/DialogPrimitives.module.css:125-128 — The CSS fix (min-width, white-space: pre) for checkbox alignment is good, but consider if this should apply to all resume-picker-item-prefix elements or only those with checkboxes to avoid unintended side effects.

🔵 Low

packages/web-shell/client/i18n.tsx:127 — The error message template 'delete.failed': (v) => \Failed to delete session.${v?.reason ? ` ${v.reason}` : ''}`` has a period before the reason, which creates awkward punctuation like "Failed to delete session. Permission denied". Consider rewording to "Failed to delete session: Permission denied" or "Failed to delete session — Permission denied".
packages/web-shell/client/components/dialogs/DeleteSessionDialog.tsx:52 — The message state is used for displaying errors inline, but it's never cleared between operations. If a user sees an error, closes the dialog, and reopens it, the stale message might still appear. Consider clearing on dialog open.
packages/web-shell/client/constants/localCommands.ts:33 — The delete command lacks an argumentHint like other commands have (e.g., release, mode). Consider adding one if the command accepts optional arguments in the future.
packages/sdk-typescript/test/unit/DaemonClient.test.ts — The PR summary mentions 4 new tests for the SDK client, but the patch shows only the new method definition. Ensure the test file includes tests for deleteSessionsData covering timeout, error responses, and success cases.
packages/web-shell/client/components/dialogs/DeleteSessionDialog.tsx:159 — The dependency array for handleDelete includes 11 dependencies. While correct, this is a code smell suggesting the function might benefit from being split into smaller handlers (e.g., handleBatchDelete and handleSingleDelete).

✅ Highlights

Excellent keyboard navigation: Full support for arrow keys, vim-style j/k navigation, Space for selection, Enter for confirmation, and / for search — matches power user expectations
Smart error categorization: Distinguishing between notFound (idempotent success) vs actual errors in the server implementation shows thoughtful API design
Good refactoring: Extracting formatRelativeTime and updating all three dialogs demonstrates good code hygiene and DRY principles
Comprehensive validation: Server validates missing/empty sessionIds array and type-checks each element before processing
Clear user feedback: Status messages show exactly what was deleted with session ID preview, and partial failures explain what went wrong

- Pass clientId to deleteSessionsData for ownership validation - Add sessionIds max length (100) and deduplication - Parallelize bridge.closeSession via Promise.allSettled - Add server-side logging for close failures - Reconcile selectedIds with search filter before delete - Prune selectedIds when search query changes - Fix notFound counting: only errors are failures - Fix partial failure double toast: single error message - Fix empty-state: show error message when load fails - Fix hardcoded English "matches" → i18n key - Remove dead targetSession parameter - Align checkbox for current session ([-] instead of spaces) - Add happy path test for batch delete - Reload session list on notFound-only response

…and improve UX - Remove clientId validation from batch delete endpoint since workspace-level access is sufficient authorization. The per-tab clientId check prevented cross-tab deletion of active sessions without real security benefit (user can bypass by resuming the session first). - Wrap filtered sessions list in useMemo to stabilize reference and prevent unnecessary keydown listener teardown/re-register on each render. - Include notFound sessions in onDeleted callback so the toast correctly reports the total count of cleaned-up sessions. Generated with AI

- Add comment documenting intentional no-clientId in batch delete - Log removeSessions filesystem errors to stderr for debuggability - Count notFound as success in deleteSession for proper UI reload - Remove dead if (!deleteSessions) / if (!deleteSession) guards - Fix partial-failure double-wrapped toast message - Reset selectedIdx when exiting search mode via Enter - Add 5 batch tests: mixed outcomes, max-100 cap, non-string validation, dedup, and file preservation on error Generated with AI

Verification Report — PR #4603

Reviewer: wenshao
Date: 2026-05-29
Branch: feat/delete-session-webshell → daemon_mode_b_main

Test Results

Test Suite	Result	Count
`packages/cli/src/serve/server.test.ts`	✅ PASS	351 tests (12 delete-specific)
`packages/sdk-typescript/test/unit/DaemonClient.test.ts`	✅ PASS	137 tests (5 delete-specific)
`packages/webui/src/daemon/workspace/DaemonWorkspaceProvider.test.tsx`	✅ PASS	9 tests (3 delete-specific)

TypeScript Check

npx tsc --noEmit reports errors in PR-touched files but they are pre-existing on daemon_mode_b_main:

web-shell/** — moduleResolution node16 requires .js extensions (pre-existing pattern across entire web-shell package)
packages/webui/src/daemon/workspace/actions.ts — deleteSessionsData not resolved cross-package without build step (runtime-only concern, covered by tests)
No new type errors introduced by this PR

Build

vite build for web-shell fails on both PR branch and base branch with same error (@qwen-code/webui/daemon-react-sdk unresolved) — pre-existing, not a regression.

Code Review Summary

Server (POST /sessions/delete):

✅ Input validation: non-empty string array, max 100, deduplication
✅ Error handling: distinguishes SessionNotFoundError (still removes transcript) vs InvalidClientIdError (preserves transcript, reports error)
✅ Normalizes Error objects to string messages in JSON response
✅ Proper use of Promise.allSettled for fault isolation

SDK (DaemonClient.deleteSessionsData):

✅ Clean typed wrapper with fetchWithTimeout
✅ Passes through response shape unchanged

UI (DeleteSessionDialog):

✅ Multi-select (Space to toggle), search/filter (/ to activate), keyboard navigation (j/k/arrows)
✅ Prevents deleting current active session
✅ Proper error surface: allFailed shows first error reason, partialFail includes detail
✅ Reuses extracted formatRelativeTime utility (good DRY refactor from ResumeDialog/ReleaseSessionDialog)

Workspace actions & hooks:

✅ Type interface extended cleanly
✅ Hook auto-reloads session list after successful delete

Verdict

✅ Ready to merge — All claimed tests pass, no regressions introduced, implementation is well-structured with comprehensive error handling and test coverage.

… test - Revert partial-failure handler to use delete.partialFail i18n key through onError only, removing contradictory onDeleted call - Add test for removeSessions unexpected throw (500 catch block)

+
+          if (failed > 0 && succeeded > 0) {
+            onError(


[Suggestion] delete.partialFail message is double-wrapped by App.tsx's onError handler, producing a contradictory toast

The onError callback in App.tsx (line 1170-1178) wraps error.message inside t('delete.failed', { reason }):

delete.failed → "Failed to delete session. {reason}" delete.partialFail → "3 deleted, 2 failed: disk full"

Combined result: "Failed to delete session. 3 deleted, 2 failed: disk full" — the prefix says total failure while the suffix reports partial success. Same in Chinese: "删除会话失败。已删除 3 个，2 个失败: disk full".

The onDeleted() removal was correct to fix the dual-toast issue, but the remaining single toast is self-contradictory.

Possible fixes:

Have App.tsx's onError dispatch the raw error.message when it's already a user-facing i18n string (e.g., check an error code/tag property)

Add a dedicated onPartialFailure callback to avoid overloading onError

Change delete.failed to not prepend the "Failed to delete session." prefix when reason already contains structured content
