Make document keyword search case-insensitive (LOWER(...) LIKE LOWER(?)) in the
list filter and SearchKnowledge / SearchKnowledgeInScopes paths so a query and
its differently-cased variant return the same results.
Classify not-found consistently as HTTP 404 (not 500) so clients read a
permanent resource.not_found instead of a retryable 5xx: map the document /
chunk not-found sentinels in the KB-access middleware (typed ErrChunkNotFound
via errors.Is), and return 404 for a missing message on the continue-stream and
message-delete endpoints.
PR #1309 plumbed user-scope into the session/message service layer so
non-owner / wrong-tenant lookups now surface as ErrSessionNotFound at
every entry point that goes through sessionRepo.Get. The handler-side
mapping, however, only existed in 4 of the 8 affected sites:
- handler/session/handler.go:GetSession ✓ already mapped (with `==`)
- handler/session/handler.go:UpdateSession ✓ already mapped (with `==`)
- handler/session/handler.go:DeleteSession ✓ already mapped (with `==`)
- handler/session/handler.go:BatchDeleteSessions ✓ already mapped (with `==`)
- handler/session/handler.go:ClearSessionMessages ✗ always 500
- handler/session/stream.go:ContinueStream session lookup ✓ (with `==`)
- handler/session/stream.go:ContinueStream message lookup ✗ always 500
- handler/message.go:LoadMessages (recent + before-time) ✗ always 500
- handler/message.go:DeleteMessage ✗ always 500
Result: a Contributor in tenant A asking for a Contributor B's session
messages got a 500 instead of 404 — the wire response leaked
"something is broken" rather than "you can't see this URL", which
breaks SDK / frontend axios interceptor error handling that keys on
HTTP status.
Two changes:
1. Add ErrSessionNotFound → 404 mapping to the 4 sites that lacked it
(ClearSessionMessages, ContinueStream's GetMessage, LoadMessages's
two paths, DeleteMessage).
2. Replace `err == errors.ErrSessionNotFound` with
`stderrors.Is(err, errors.ErrSessionNotFound)` everywhere. Sentinel
error comparison must use errors.Is so wrapped errors
(`fmt.Errorf("...: %w", ErrSessionNotFound)`) still match. Today no
service-layer caller wraps, but a future refactor that does would
silently turn 404s into 500s with no test catching it.
Tests:
- internal/handler/message_session_not_found_test.go covers the four
new mapping sites in handler/message.go (LoadMessages-recent,
LoadMessages-before-time, DeleteMessage) and pins the wrapped-error
behaviour with a dedicated regression test that fmt.Errorf("%w") a
sentinel must still be detected as ErrSessionNotFound. The bare
handler is hit through gin.Engine + middleware.ErrorHandler so the
response shape matches production exactly.
- PR #1309's existing service-level tests (session_user_scope_test,
session_test on the repository) still pass — this PR is a strictly
handler-layer follow-up.
- Added Swiper library to package dependencies for improved UI components.
- Updated chat API to include summary model ID in message handling, allowing for more flexible model selection.
- Enhanced InputField component to manage model selection and state more effectively.
- Improved event handling in chat components to support new model features and ensure accurate message processing.
- Refactored SVG assets for better visual consistency and updated styles for improved user experience.
