* fix(vertex_ai/files): upload batch files in a single media request to fix 499s on large uploads PR #31036 switched the vertex batch file upload from a single GCS media upload to a chunked resumable session. The resumable path sends the body as many sequential PUTs, each waiting a full round-trip to GCS before the next, so a multi-GB upload accumulates hundreds of round-trips and overruns the client/load-balancer request timeout, surfacing as 499s (client closed connection) on files as small as 500MB. This was a regression from the last-known-good commit, where the upload completed as one continuous request. Revert the batch upload to a single uploadType=media request, but stage the transformed payload to a temp file first so peak memory stays bounded (the goal of the resumable rewrite) without the per-chunk round-trips. The temp file is closed deterministically (TemporaryFile unlinks on close), not left to the GC. The now-unused resumable chunked-upload plumbing is removed. Also swap the per-row transform's stdlib json for orjson (parse + serialize), which is ~4x faster on this hot path; the streaming body now emits compact orjson bytes. The request stays synchronous, so the returned file object is real and POST /v1/batches keeps working immediately against the uploaded object. Tests: single media request carries the whole payload with a real Content-Length (no chunked transfer-encoding); failed upload raises; the staged temp file is closed deterministically; byte-for-byte transform parity. * test(vertex_ai/files): mock single media upload POST instead of removed resumable method test_avertex_batch_prediction patched BaseLLMHTTPHandler._aresumable_chunked_upload, which was removed when the batch jsonl upload moved from a chunked resumable GCS session to a single uploadType=media request. Patch the raw httpx.AsyncClient.post that _astage_and_upload_media issues so the real staging, upload and response transform run while the GCS object response is mocked, and assert the media URL and Content-Type. * fix(vertex_ai/files): forward request timeout to media upload, drop orjson, sort imports Forward the per-request timeout through _stage_and_upload_media / _astage_and_upload_media to the GCS POST. Every other upload branch forwards it; the new media path was dropping it, so a caller-provided timeout was silently ignored (the files path passes 600s by default, but a custom request_timeout would not have reached this upload). Regression test asserts the resolved timeout reaches the request (mutation-verified). Revert the orjson swap in the batch transform: importing orjson at module load in this core-path file broke `import litellm` on environments without orjson (the Windows import test). Back to stdlib json; the upload leg dominates large uploads anyway, so the transform-side win was marginal. Fix import ordering in llm_http_handler.py (I001) introduced by the new imports. * fix(vertex_ai/files): stream batch upload to GCS instead of staging to a temp file Addresses a disk-exhaustion concern: staging the full transformed batch body to a local temp file before the GCS request meant an authenticated user could fill the proxy's temp volume with large concurrent uploads (on top of Starlette's input spool). GCS's simple/media upload accepts chunked transfer-encoding, so stream the transform straight to the single media request instead. Each block is produced on a worker thread (the transform never runs on the event loop) and sent chunked, so the body is neither buffered in memory nor written to disk, and the upload is still one continuous request (no per-chunk round-trips, no 499). Drops the temp-file staging, the tempfile/IO imports, and Content-Length computation. Regression test asserts the upload streams (chunked transfer-encoding, no Content-Length) and creates no temp file; mutation-verified that reintroducing staging fails it. |

In total litellm runs 1000+ tests
[02/20/2025] Update:
To make it easier to contribute and map what behavior is tested,
we've started mapping the litellm directory in tests/test_litellm
This folder can only run mock tests.
