Use useRef to store saveFile reference and remove it from useEffect
dependencies to prevent cleanup from re-triggering on reference changes.
Also normalize metadata before comparison when clearing dirty state to
ensure filtered tools match correctly.
Simpler approach: disable the view picker toggle when preview is running,
preventing users from switching views during active runs.
This replaces the previous mounted ref guard approach (commits a0188bd9b5,
b7f1eb9b7b, 8332f0de2b) which added complexity to handle post-unmount
operations. Disabling the toggle is more direct and follows KISS principle.
Changes:
- Add disabled prop to ViewPicker based on isResponding state
- Revert mounted ref guards in use-chat-flow-control.ts
- Revert isMountedRef parameter in use-nodes/edges-interactions-without-sync.ts
- Revert defensive type check in markdown-utils.ts (no longer needed)
In React StrictMode (dev mode), effects are run twice to help detect
side effects. The cleanup-only pattern left isMountedRef as false after
StrictMode's simulated unmount-remount cycle, causing stop/cancel
operations to be skipped even when the component was mounted.
Now the effect setup explicitly sets isMountedRef.current = true,
ensuring correct behavior in both development and production.
Related to a9c5201485 - when switching views during active preview run,
the markdown preprocessors could receive non-string content (e.g., frozen
arrays from immer). Returning the original value caused ReactMarkdown to
fail with "Cannot assign to read only property" error.
Now both preprocessLaTeX and preprocessThinkTag return '' for non-string
input, preventing runtime errors during view switches.
When switching from graph view to skill view during an active preview run,
SSE callbacks continue executing and attempt to update ReactFlow node/edge
states. This could cause errors since the component is unmounted.
Add optional `isMountedRef` parameter to `useNodesInteractionsWithoutSync`
and `useEdgesInteractionsWithoutSync` hooks. When provided, operations are
skipped if the component has unmounted, preventing potential errors while
allowing the SSE connection to continue running in the background.
BREAKING CHANGE: `useNodesInteractionsWithoutSync` and
`useEdgesInteractionsWithoutSync` now accept an optional `isMountedRef`
parameter. Existing callers are unaffected as the parameter is optional.
The sidebar layout was broken when ArtifactsSection expanded - it would
squeeze the FileTree and neither area could scroll. This restructures the
layout so each section has its own scroll container with proper height
constraints.
Remove enabled condition so data is fetched when component mounts,
allowing blue dot to show when files exist even before expanding.
TanStack Query handles request deduplication automatically.
- Replace placeholder with functional ArtifactsSection component
- Add ArtifactsTree component for file tree rendering
- Support expand/collapse with lazy loading
- Show blue dot indicator when collapsed with files
- Add empty state card with hint text
- Add download button on file hover
- Add i18n translations (en-US, zh-Hans)
