Three tests covering the CC→Responses→Anthropic finalize path:
- TestStreamingParallelToolUseNoGhostDelta: full end-to-end with two
parallel tool_calls, asserts every content_block_delta targets a
started block
- TestStreamingParallelToolUseSecondToolPackedArgsDone: focused test
where tool 1 streams deltas and tool 2 has packed .done args
- TestStreamingThreeParallelToolsAllPackedDone: three tools all with
packed .done, the most extreme case
All three fail on unfixed code (ghost deltas on wrong indices) and
pass after the fix.
Skip the Responses API intermediate representation on the /v1/messages
force-chat path. Previously every streaming token ran through two state
machines (CC→Responses→Anthropic); now it runs through one (CC→Anthropic).
New file backend/internal/pkg/apicompat/chatcompletions_anthropic_bridge.go:
- AnthropicToChatCompletionsRequest: request-side direct conversion
- ChatCompletionsResponseToAnthropic: non-stream response direct conversion
- ChatCompletionsChunkToAnthropicEvents + Finalize: single streaming state machine
openai_gateway_messages_chat_fallback.go rewired to use the direct bridge.
Existing 7 ForceChatCompletions end-to-end tests pass unchanged; 22 new
unit tests added including equivalence tests vs the double-conversion path.
resToAnthHandleFuncArgsDone used state.ContentBlockIndex directly
instead of looking up from OutputIndexToBlockIdx like
resToAnthHandleFuncArgsDelta does. When multiple tool_calls arrive
in parallel and arguments come as a packed .done (no prior delta),
the second+ tool would emit content_block_delta on an index that
was never content_block_start'ed, causing Claude Code to report
"Content block not found".
Fix: resolve block index from OutputIndexToBlockIdx, and skip the
delta if the block is already closed or the index doesn't match
the current open block.
Closes#4193
Mirror the Admin UI Server-Timing opt-in for user-facing pages so
authenticated callers can inspect total/app/db/redis/deps metrics on
session, profile, keys, usage, payment, and related user APIs.
- Collect when X-User-UI-Request=1 or path is on the user allowlist
- Emit for non-admin only on allowlisted paths (header is not auth)
- Exclude payment public/webhook surfaces
- Mark matching SPA requests and allow the new CORS request header
Add a dedicated client first-message timeout while preserving the legacy 30-second default.
Use the resolved value for both the WebSocket read deadline and structured timeout logs, and document tuning for large requests or slow links.
Add configuration, validation, handler, and resolver regression coverage.
Refs #4158
ChatGPT OAuth may normalize explicit image size controls to auto while returning smaller raster bytes. Decode final image headers so Images API metadata and tier billing reflect the actual output for both streaming and non-streaming OAuth responses.
Enrich openai.upstream_failover_switching structured logs with proxy
identity fields (proxy_id, proxy_name, proxy_host, proxy_port) so
operators can see which outbound proxy failed when switching accounts.
Matches the existing gateway.forward_failed / websocket_proxy_failed
logging pattern.
Add proxy_id/proxy_name/proxy_host/proxy_port fields to openai.websocket_proxy_failed so operators can identify which proxy failed without extra lookups. Matches the existing gateway.forward_failed logging pattern.
Add a toggleable group ID column in /admin/groups column settings.
It shows the group id (e.g. #1), is hidden by default for new and
existing admins via column-settings version migration, and remains
sortable against the existing backend sort_by=id support.
Expose API key ID in the keys table column settings so users can show
or hide it. Hidden by default; bump column-settings version so existing
preferences also keep ID hidden until toggled on.
