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> |

fix(langfuse_otel)!: send the completion start time (#45597)
* fix(langfuse_otel): send the completion start time langfuse_otel never set langfuse.observation.completion_start_time, so Langfuse showed no time to first token for any call, streamed or not. The legacy langfuse callback already sends kwargs["completion_start_time"]. Send the same value as an ISO timestamp with an explicit offset. * fix(langfuse_otel): type kwargs and test against a real span Type the kwargs of _set_langfuse_specific_attributes as dict[str, Any], the declared type of model_call_details, so the new completion start time read adds no unknown-type errors. The tests now check a real SDK span instead of patching safe_set_attribute, and the parameter is typed. * fix(otel): send the completion start time from the v2 Langfuse mapper With LITELLM_OTEL_V2 the langfuse_otel spans come from LangfuseMapper, which had no completion start time either. Carry the payload's completionStartTime on LLMCallSpanData for streamed calls, the same calls that get time_to_first_chunk_seconds, and map it to langfuse.observation.completion_start_time. * fix(langfuse_otel): take the logging kwargs as a read-only Mapping The new kwargs annotation tripped LIT001. Both helpers only read the logging kwargs, so type them Mapping[str, Any] instead of dict. * fix(langfuse_otel): time /v1/messages streams from the call start and send the V2 completion start time like the default emitter * fix(langfuse_otel): time Gemini, Interactions and A2A streams from their first chunk and send the start time as JSON The native Gemini, Interactions and A2A streams never recorded a first chunk, so with completion_start_time now sent both emitters showed TTFT equal to latency on them. They now record it, and Gemini and Interactions take the call's start time like /v1/messages. Both emitters send the completion start time as a JSON string, the form the Langfuse SDK and the langfuse callback send, through one serializer. * fix(langfuse_otel): time A2A streams from the call start and record a cached replay's first event A2A streams took their start time when the iterator was built, so their latency left out the work before it. They now use the call's start time like every other route. Cached /v1/messages stream replays recorded no first event, so their time to first token fell back to the end time. The replay now records it on the first event it yields. The tests use the real Interactions config and typed logger hooks. * fix(a2a): time streamed A2A calls from before the agent card fetch and make the cached replay test clock-free * test(a2a): type the card fetch test and stop rebinding the seed helper's recorder * test(otel): expect completion_start_time and cache_hit in the B3 span keys --------- Co-authored-by: mateo-berri <277851410+mateo-berri@users.noreply.github.com> |

test(unit): wait on the work itself instead of fixed sleeps (#46261)
* test(unit): wait on the work itself instead of fixed sleeps in 21 flaky files Replace sleeps that raced background logging, cache writes, refreshes and thread work with either awaiting that work directly (logging worker flush, the batch logger's flush_queue, the tasks the call spawned, thread joins) or an Event the test's own fake sets when it runs. Each wait keeps a 5s hang guard that never decides pass or fail. Tests that need a fake clock, real sockets, or measure latency are left unchanged, and no production code moves * test(unit): await the tasks each completion spawns instead of yielding once The logging tests yielded once with asyncio.sleep(0) so the task that enqueues the success log could run before the worker flush. That relied on the enqueue happening before the task's first await. Snapshot the running tasks around each acompletion call and await the ones it spawned, so the guarantee holds however many steps sit before the enqueue |

test: move tests/test_litellm root and small trees into tests/unit (#43186)
* ci: run the unit_selection.sh shard files on every event instead of only fork pull requests Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com> * ci: rename fork-flag to unit-flag now that it applies on every event * test: move tests/test_litellm root and small trees into tests/unit Pure renames, no content changes. Follow-up commits in this PR fix references, merge the three files that already existed in tests/unit, keep live-provider tests in tests/test_litellm and wire CI. * test: carry tests/test_litellm conftest isolation into tests/unit Callback lists, routing fallbacks, cached HTTP clients, logger state, AWS, proxy-URL and keychain env, and session-end client cleanup now reset for unit tests too. The environment isolation owns its MonkeyPatch so a test's own monkeypatch is undone before the model-cost teardown runs. * test: merge, split and prune the moved root and small-tree tests Merge batches/test_batch_utils.py and the chat_completions and messages dispatch tests into the files that already existed in tests/unit. Keep the live Gemini interactions tests, the async image-fetch format test and the OpenAI embedding scorer test in tests/test_litellm since they need real network or keys. Put test_router.py under tests/unit/test_router so the existing package no longer shadows it. Delete eight tests the audit found superseded by stronger ones kept in this move. * ci: run the moved root and small-tree tests under their legacy flags Add the misc and responses-caching-types flags to unit_selection.sh and CircleCI, extend enterprise-routing and mcp-integration, and point the legacy GHA shards, Makefile, redis-compat workflow, merge smoke manifest and change classifier at the new paths. * test: make the new tests/unit directories packages tests/unit/test_package_layout.py requires every directory to carry an __init__.py, and without one the moved and retained test_litellm_responses_bridge.py modules collide on import. * test: scope the unit socket block to tests/unit in shared sessions The GHA shards collect the legacy test-path and the unit selection in one pytest session. The unit conftest's loopback-only block leaked into legacy modules that reach the network at import. The legacy conftest now lifts the restriction at collect and setup time, and the unit conftest re-applies it when collecting its own modules. * test: give the shard-script tests their own GITHUB_OUTPUT They only passed where the runner set it. The CircleCI unit job's env allowlist drops it, so the script's redirect failed there. * test: point the router and module-deletion checks at tests/unit router_code_coverage and code_qa_check_tests only searched tests/test_litellm, so the moved router tests no longer counted. The two silent-experiment tests the audit deleted were the only direct callers of those methods; they are replaced with tests that assert the forwarded shadow request and the recursion guard. --------- Co-authored-by: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com> |
