POST /credentials let a duplicate name hit the unique index and handed back
Prisma's "Unique constraint failed" as a 500, so callers string-matched that
message to tell a caller mistake from a server fault. The unique violation now
maps to a 409 whose message names the PATCH route, two concurrent creates of
one name agree on it, and the detection lives in a repository helper the five
hand-rolled copies can move onto later
PATCH /credentials/{name} took a CredentialItem body, so the model_id the
Terraform adopt path sent was dropped. It now accepts UpdateCredentialItem and
shares the deployment lookup with create. Both handlers take the router as a
FastAPI dependency instead of reading the proxy global, which is what the
tests override
A guardrail that rewrites text and hands back tool_use arguments that are
not a JSON object used to leave the text rewrite applied when the request
was rejected, so failure logging saw a half-rewritten request. Every
rejection now happens before any write to system or messages.
The router clamps a negative request_retry_count found in request metadata before counting a failure, and the proxy strips a client-supplied request_retry_count with the other router-reserved metadata fields. The rust OCR lifecycle test that trips the per-request cap now plants request_retry_count instead of attempted_retries, which the cap no longer reads since the previous commit
num_retries_per_request has always capped the retries of one request with its fallback hops included. #40930 started reading the per-hop attempted_retries counter instead, and every fallback hop restarts that counter at zero, so a request could spend a fresh retry budget on each hop and the legacy fallback cap test started seeing the hop run.
Router.log_retry now also keeps request_retry_count on the request metadata, incremented on every retry and fallback hop and never truncated the way previous_models is, and max_retries_per_request_hit reads that count. The flat retry records, the litellm_metadata coverage and caps above four from #40930 stay as they are, and the legacy test goes back to its previous_models == 0 assertion.
httpx.Headers.items() comma-joins repeated header names, so the rebuilt
response iterates multi_items() and keeps every value, matching what the
raw openai client exposes on e.response.headers
The streaming bridge restored the namespace before deciding whether a tool call was a custom tool, so a namespaced function sharing a short name with a nested custom tool streamed back as a custom_tool_call. Classify on the raw chat tool name first, the way the non-streaming path already does.
The guardrail merge only stripped the namespace prefix and grammar suffix from the ends of the edited description, so a guardrail appending text after the grammar block left the block in the member description and the chat conversion appended it a second time. Strip the first occurrence of each instead.
