fix(streaming)!: fail a stream that ends without a finish reason (#47665)
* fix(streaming): fail on clean EOF without finish reason * fix(streaming): cover shared OpenAI-compatible EOF paths * test(router): complete mocked streaming responses * fix(streaming): keep the EOF error message and cover Anthropic clean EOF The request-less RemoteProtocolError tripped exception mapping into 'The .request property has not been set.' for non-OpenAI providers. Adds Anthropic and generic-chunk unit tests, an integration test across chat, the /v1/messages bridge and the /v1/responses bridge, and moves main's token-estimate test onto a finished stream with a sibling that checks the cut stream still bills the estimate on its failure log. * fix(streaming): count a finish reason any chunk sent, keep LangGraph async streams whole Gemini marks every chunk unfinished and a later usage chunk reset intermittent_finish_reason, so a finished Gemini stream failed at EOF. LangGraph's __aiter__ opened a new aiter_lines on every wrapper call, which hit StreamConsumed after the first chunk and now surfaced as a false EOF error instead of a silent truncation. * fix(streaming): keep the synthetic stop for a stream that sent no chunks Gemini's OpenAI-compatible endpoint answers with only [DONE] when reasoning uses up max_tokens. Failing every openai/azure stream that sent nothing turned that 200 into a 500, while every other provider already kept the stop for an empty stream. Adds integration cells for Gemini's trailing usage chunk, multi-event LangGraph runs, a mocked deployment and the [DONE]-only answer. * test(streaming): keep pytest.raises to one statement, drop the spend read for an empty stream An empty stream writes no spend row on main either, so the [DONE]-only cell checks only what the client sees. * fix(streaming): read the chunk's finish reason for the sticky flag * fix(agentcore): end a stream on messageStop when the runtime sends no metadata or final message * test(streaming): pin the logged-chunks guard, inject the LangGraph client, use current model names * fix(agentcore): say why the end-of-stream flags rebind * test(streaming): cover an AgentCore runtime that ends on messageStop through the proxy * test(streaming): cover SDK clients, request fallbacks and a concurrent burst for a cut stream * test(agentcore): inject the async transport instead of patching the aiohttp flag * test(guardrails): end the decision model chat fixture with a finish reason, as a real stream does * test(streaming): shape the AgentCore and LangGraph fixtures like captures from a real runtime and server * test(streaming): keep each stream's ending and land every spend row once through a spend log outage * test(streaming): end each stream by its provider's finish after a proxy worker is killed mid burst * test(streaming): run the outage test as one burst before and one during the outage instead of a capped wave loop * test(streaming): connect the outage test's proxy to the relay without TLS so its trigger sees the spend-log insert on an ssl=on Postgres * test(streaming): type the new stream EOF unit tests * test(streaming): a merged reasoning stream cut mid reasoning now fails Main's think tag test expected a stream that ends mid reasoning without a finish reason to finish with a closed think block. With this PR that stream fails, so the case moves to its own test that expects MidStreamFallbackError with the open think block as the partial content --------- Co-authored-by: King Star <mcxin.y@gmail.com> Co-authored-by: yucheng-berri <293926326+yucheng-berri@users.noreply.github.com> |

fix(streaming): keep merged think tags balanced and split SSE lines only on CR/LF (#48755)
* fix(vertex_ai): split Gemini SSE lines on CR/LF only so U+2028 in text keeps the stream The Gemini and Vertex AI streaming path read the SSE body with httpx iter_lines()/aiter_lines(). Those follow str.splitlines(), which also breaks on U+0085, U+2028, U+2029, \x0b, \x0c and \x1c-\x1e. JSON leaves U+0085, U+2028 and U+2029 unescaped inside strings, so a data: line whose text holds one of them was cut in two. The tail is not a data: line and the head never parses, and the accumulate-and-retry fallback then carries the unparsed prefix forward, so every later event is appended to it and the stream ends with no more content and no usage. SSE lines end only at CRLF, LF or CR. The new iter_sse_lines/aiter_sse_lines split decoded text on exactly those, treating a CR at the end of one chunk and an LF at the start of the next as one break. The first request and every long-decode hop now read through them. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(streaming): keep merged think tags balanced and split shared SSE lines only on CR/LF Close an open <think> block on the first content or tool-call delta and at stream end, reopen it when reasoning returns, and route the shared chat completions stream through the SSE line splitter so U+2028 and U+2029 inside JSON no longer drop chunks. * fix(streaming): exact-match the SSE [DONE] marker in BaseModelResponseIterator * fix(streaming): split every SSE reader on CR/LF only and keep the logged think block closed Switch the remaining httpx stream readers (Anthropic chat, Google GenAI, Interactions, Codestral, openai_like, Predibase, LangGraph, Vertex Agent Engine, A2A providers, Azure AI agents, sandboxes, the A2A endpoint, and others) from iter_lines/aiter_lines to iter_sse_lines/aiter_sse_lines, so a raw U+2028 or U+2029 inside a JSON string no longer splits an event. Keep the chunk that closes a think block in the logged and cached response when a stream ends without a finish_reason, close the block before a legacy function_call, and make sync Codestral FIM streaming send stream=true and use the text-completion-codestral stream parser. Test fakes that only mocked iter_lines now stream real httpx bytes and assert the content they feed in. * fix(streaming): split buffered SSE parsers only on CR and LF, shard the codestral tests Buffered SSE and JSONL parsers used str.splitlines(), which also breaks on U+2028, U+2029 and U+0085 that JSON allows raw inside strings. They now use split_sse_lines from sse_lines.py, which also gains a str.split fast path. Adds tests/unit/llms/codestral to the unit workflow shard. * fix(streaming): keep U+2028 in restamped Anthropic frames and fold CRLF before splitting SSE lines * test: type the new stream tests, drop a comment, and benchmark the SSE line splitter * test: type the iterator class parameters in the line-separator stream tests * fix(responses): stream tool call arguments opened in a text chunk * fix(responses): hold a tool call that shares a chunk with text until the text ends * test: type the a2a SSE handler helper and the sandbox fake responses --------- Co-authored-by: Tim Vink <vinktim@gmail.com> Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com> Co-authored-by: mateo-berri <277851410+mateo-berri@users.noreply.github.com> Co-authored-by: michelligabriele <gabriele.michelli@icloud.com> |

chore(typing): clear 670 basedpyright Any errors by validating provider payloads at the boundary (#45388)
* chore(typing): validate provider payloads at the boundary to clear 464 basedpyright Any errors Replaces untyped reads of decoded JSON in 48 provider, guardrail and proxy modules with one pydantic validation at the point the payload enters the module, so every value read afterwards carries a real type. reportAny 6111 -> 5663 and reportExplicitAny 1416 -> 1400. No basedpyright, ruff-strict or type-discipline rule is higher repo-wide or in any single file, and no cast, ignore or suppression marker was added. * chore(typing): replace 47 Any annotations that every caller already satisfies with object Each annotation here is a parameter or return type whose value is only stored, compared, logged or forwarded, so object describes it exactly and no function body changes. A site was kept only if no basedpyright, ruff-strict or type-discipline rule rose in any file that references it. reportExplicitAny 1400 -> 1353 and reportAny 5663 -> 5655. * chore(typing): type upstream responses and loose annotations across providers, proxy and integrations Second pass of the Any reduction. Decoded upstream JSON is validated once at the provider boundary and read through typed views afterwards, annotations that every caller already satisfies move from Any to a concrete type, and the nine search transformations validate each result item on its own so error text no longer carries the item index. No cast, no type: ignore, no suppression marker and no budget file edit * ci(unit): run the brave, google_pse, nlp_cloud and opensandbox tests in the providers shard |

test: move whole-unit legacy test files into tests/unit and delete dead skips (#44807)
* test: delete unconditionally skipped legacy tests * test: move whole-unit legacy test files into tests/unit * test: keep moved legacy tests free of import-time global state * test: keep the module-level invocation scan pointed at tests/local_testing * ci: drop the agent_testing CircleCI job emptied by the move * test: fix moved-test isolation and router coverage * test: add Tinyfish search package marker * test: isolate moved tests from logger state leaks * test: isolate Helicone logging fixture state * test: isolate Vertex pass-through credentials between moved tests * test: cancel S3 periodic flush tasks started by moved tests * ci: restore CircleCI assistant test selection after move * test: prevent Datadog datetime import shadowing * ci: drop the litellm_assistants_api_testing CircleCI job emptied by the move * test: deduplicate imports in rebased unit tests * test: remove duplicate passthrough router patch import * test: remove moved legacy source files after rebase * test: align moved tests with rebased main * test: carry main's legacy-file edits into moved destinations * test: make the moved cost map fallback tests assert the fetch and the backup The four fallback cases only checked the result was non-empty, so they still passed with integrity validation disabled. They now inject a mock client, assert one fetch happened, and assert the result is exactly the local backup with the fallback reason recorded. --------- Co-authored-by: yuneng <yuneng@berri.ai> |
