Summary by CodeRabbit

  • Bug Fixes
    • Improved attachment loading by limiting thumbnail fallback attempts when an image source fails.
    • Preserved fallback behavior when a thumbnail is available.

📝 Walkthrough

Walkthrough

Attachment components now monitor attachment-server availability and poll for recovery. Galleries and viewers render localized unavailable messages when the server is unavailable. Image and thumbnail failures report server errors, with one-time thumbnail fallback handling. The attachments menu remains visible and becomes disabled during outages.

Changes

Attachment server availability

Layer / File(s) Summary
Track attachment server status
specifyweb/frontend/js_src/lib/components/Attachments/attachments.ts
The attachment module records server status, checks the configured read endpoint, polls while listeners exist, and exposes useAttachmentServerStatus.
Render unavailable attachment states
specifyweb/frontend/js_src/lib/components/Attachments/index.tsx, specifyweb/frontend/js_src/lib/components/Attachments/Viewer.tsx
The attachments view and viewer render AttachmentServerUnavailable when the server is unavailable. Otherwise, they preserve gallery and content rendering.
Report attachment loading failures
specifyweb/frontend/js_src/lib/components/Attachments/Preview.tsx, specifyweb/frontend/js_src/lib/components/Attachments/Viewer.tsx
HTTP thumbnail and image failures report server unavailability. Transformed images try thumbnail fallback once before rendering the unavailable state.
Disable unavailable attachment navigation
specifyweb/frontend/js_src/lib/components/Header/index.tsx, specifyweb/frontend/js_src/lib/components/Header/menuItemDefinitions.ts
The attachments menu remains available when the user has table permission and becomes non-interactive when the attachment server is unavailable. MenuButton exposes aria-disabled for this state.

Testing Instructions ⚠️ Warning The Testing instructions section is empty, while the PR changes attachment previews/viewers, gallery actions, header navigation, and health polling. Add clear steps to simulate server outage and recovery, verify disabled navigation/actions and unavailable messages, test preview/viewer failures, and confirm polling and logs.

In `@specifyweb/frontend/js_src/lib/components/Attachments/attachments.ts`:
- Around line 90-102: Update startAttachmentServerHealthPolling so every
subscriber receives the shared cleanup function, including when healthCheckTimer
is already active. Ensure cleanup stops the interval only when
serverStatusListeners is empty, while preserving the existing polling setup and
status handling.
- Around line 71-73: Update reportAttachmentServerFailure to call
checkAttachmentServer immediately and set the attachment server status to
unavailable only when that health check fails; do not mark global availability
unavailable solely from an individual attachment error.
- Around line 52-56: Update setAttachmentServerStatus to log only transitions
between available and unavailable, including a timestamp for each
connection-loss or restoration event; preserve the existing early return for
unchanged statuses and listener notification behavior.

In `@specifyweb/frontend/js_src/lib/components/Attachments/index.tsx`:
- Around line 246-268: Gate attachment actions on attachmentServerStatus: in
Attachments/index.tsx, disable the Import button when the server is unavailable
and expose the unavailable reason via its tooltip or nearby message; in
Attachments/Viewer.tsx, hide or disable Download and Open in new tab when
originalUrl targets an unavailable server. Preserve normal action behavior when
the server is available.

173-189: 🚀 Performance & Scalability | 🔵 Trivial | ⚡ Quick win

Avoid polling for users without attachment access.

Line 173 subscribes every HeaderItems instance to useAttachmentServerStatus(). The hook starts startAttachmentServerHealthPolling() when subscribed. menuItemDefinitions.ts can omit the attachments item when hasTablePermission('Attachment', 'read') is false, but this header still starts polling. Gate the subscription on attachment-menu visibility, or move the hook into an attachments-only menu item component.
