Merge remote-tracking branch 'origin/litellm_internal_staging' into litellm_scx_ai_provider

Browse source 
Resolves the three conflicts against the JSON provider registry refactor. The
hardcoded api.scx.ai base-url branch in get_llm_provider_logic.py is dropped in
favour of the generic JSONProviderRegistry.get_by_base_url lookup, which reads
the same base_url and api_key_env from providers.json and additionally honours
an explicitly passed api_key. constants.py and types/utils.py keep both the
cognition and scx-ai entries added on either side.

name: "Detect relevant changes"
description: >-
Classify the pull request's changed files with .circleci/scripts/classify_changes.sh
and expose decision=run|skip for one category. backend means anything outside ui/,
docs/ and markdown; ui means the dashboard sources alone. decision=skip lets callers
short-circuit expensive steps while the job still completes successfully and satisfies
its required status check, which a paths: filter cannot do because a workflow that
never starts never reports. The file list comes from the pull request itself rather
than from a git diff, because the checked-out merge ref is recomputed as the base
branch advances and would otherwise attribute the base branch's own commits to the
pull request. The decision defaults to run for any non pull_request event or whenever
the changed set cannot be resolved, so jobs are never skipped when the classification
is uncertain.

The caching suite in tests/local_testing, which runs nowhere. Every job that globs that
directory either deselects it (local_testing_part1 and part2 carry `-k "... and not caching

names these files the way redis_caching_unit_tests names test_dual_cache.py. Measured
2026-08-20 by collecting the directory under each job's own selector: 118 tests across
these eight files are selected by none of them. Listed so the gap is a decision rather

The last file of a second mirror that sat beside tests/test_litellm and ran nowhere. Its
other 33 files landed in the real mirror during August 2026, 30 as moves and 3 by merging

its live twin was rewritten from 1268 lines to 9434, and of the 19 tests here 5 have no

is a judgement about the endpoints, not a merge. Revisit by deciding which of the five

tests live under tests/proxy_migration_tests. Measured 2026-08-20: 24 of its 28 tests pass
and the 4 in TestMigrationSQLIdempotency fail, because 13 migrations from 2026-03 onward use
bare CREATE TABLE, ADD COLUMN, CREATE INDEX and ADD CONSTRAINT rather than the guarded forms
this file requires. It also matches those keywords inside SQL comments, so two further
migrations are reported that are in fact fine. Wiring it up means deciding what to do about
the 13 first, and they cannot simply be edited: Prisma checksums an applied migration, so a
changed one breaks migrate deploy for existing installs

The proof must be completely e2e with no mocks, using actual LLM calls costing real $$$ if applicable. `pytest` commands are not enough
Show ONLY the latest run: capture Before at the merge base and After at the PR's current tip, and when new commits change behavior, replace this whole section with the fresh run instead of stacking it on top of older ones. The run must be up to date. As soon as a new commit is made and it makes this PR description's after sha stale (it's no longer tip of PR), you must re-run the QA
Structure the section exactly as below: Before and After one heading level below this section, each naming the commit hash it was captured at, one lower-level heading per case inside each, the same case names in the same order on both sides, and numbered steps (command, observed output) under every case, never loose prose; shared setup (config, payloads) goes above Before, and with a single case, drop the case headings and number the steps directly

"""Three invariants about what lives in .github/workflows/ and what its names mean.
`.github/workflows/` is a directory GitHub reads, not a place to keep things. Every
file at its top level is parsed as a workflow, so a script or a data file parked there
is either an invalid workflow or an orphan nobody can find. A subdirectory is not read
at all, so helper files may live in one. GitHub accepts both `.yml` and `.yaml`, and
this repo spells them `.yml`, which is a naming rule rather than a validity one and is
reported separately. And the `_` prefix is the repo's only signal that a workflow is a
reusable building block rather than something that runs on its own, which is worth
nothing unless it is true both ways.
WF001 a top-level file in .github/workflows/ that is not a workflow at all
WF002 a workflow whose only trigger is `workflow_call` but is not `_`-prefixed
WF003 a `_`-prefixed workflow that no other workflow can call
WF004 a real workflow spelled `.yaml` where this directory spells them `.yml`
A workflow with `workflow_call` alongside a human trigger is deliberately dual-mode
and belongs under its plain name, so only the call-only ones are held to WF002.

"""One-shot 7-day heads-up sweep for the Agent Shin rollout.
Posts a friendly "the OSS triage bot kicks in next Monday" comment on every
open external PR/issue that currently *would* fail the new rubric — i.e.,
every PR/issue Agent Shin would close once the rollout completes. The point
is to give contributors a full week to fix their description before the bot
ever takes a destructive action, so nobody is surprised by an auto-close.
The script is designed to run **exactly once** at rollout, fired by a manual
``workflow_dispatch`` (``dry_run=false``) on the heads-up workflow. Re-runs
are safe: every comment is stamped with the hidden ``HEADS_UP_MARKER`` and
PRs/issues that already carry the marker are skipped.
Dry-run vs. real run
--------------------
Defaults to dry-run. Passing ``--close`` flips into real mode. Every GitHub
mutation goes through ``_agent_shin_actions``, which has a one-line
``if dry_run: log else: do_it`` per call, so the only difference between a
dry-run preview and the real run is the call site that actually hits the
GitHub API.
Local preview::
python3 .github/scripts/triage_rollout_heads_up.py --repo BerriAI/litellm
Real run (the manual rollout dispatch uses this)::
python3 .github/scripts/triage_rollout_heads_up.py --repo BerriAI/litellm --close

# One caller for every tests/test_litellm shard, replacing the nine thin workflow
# files that each wrapped a single call to _test-unit-base.yml. Adding a shard is
# now one matrix entry rather than a new file.
#
# `name` is the shard id and nothing else, so each check reports as
# "<shard> / Run tests" exactly as it did when the shard had its own file. Those
# strings are the branch ruleset's required contexts, so they are load-bearing:
# renaming an entry renames a required check and the ruleset stops matching it.
#
# Every entry states its timeouts even when they equal the base workflow's
# defaults. An absent matrix key renders as an empty string, which is not a
# number, so a partially-specified entry would fail the call rather than fall
# back to the default.
#
# tests/proxy_unit_tests keeps its own caller (test-unit-proxy-db.yml): it is
# already a matrix and carries a shard-coverage guard that reads that file by
# name. Folding it in here is a follow-up, together with generalising that guard
# into assert_ci_coverage.py.

name: Agent Shin — rollout heads-up (one-shot)
# Fires the 7-day heads-up comment on every open external PR/issue that the
# new triage bot would auto-close. The real sweep is a deliberate one-shot:
# trigger it at rollout via a manual `workflow_dispatch` with `dry_run=false`.
# The script is idempotent (skips items that already carry the
# `<!-- agent-shin:rollout-heads-up -->` marker), so a re-run is harmless.
#
# The automatic push trigger runs DRY-RUN only, so merging the script to
# `litellm_internal_staging` never posts a comment; it just confirms the
# workflow is wired up. Posting real comments requires the manual dispatch,
# which is also the only trigger that exposes `OPENAI_API_KEY`. The heads-up
# is intentionally NOT gated on `AGENT_SHIN_ENABLED`: it has to warn
# contributors while that flag is still off, ahead of the flip that turns on
# auto-closing.
#
# The workflow is a thin shell over `.github/scripts/triage_rollout_heads_up.py`.
# Dry-run vs. real run differ in EXACTLY one CLI flag (`--close`), added only
# on a manual dispatch with `dry_run=false`.

`make check` (f.k.a. `make pre-commit`, which still works identically as an alias) saves its complete output to a log file in .git (overwriting previous logs) and prints that path as its first and last output lines. To inspect a run, read or grep that log instead of re-running the multi-minute checks just to see a different slice
`make check`, `make lint`, `scripts/pre_commit_lint.sh`, and the standalone budget gates (`scripts/ruff_strict_gate.py`, `scripts/type_discipline_gate.py`, `scripts/type_check_gate.py`) each hold one of 2 machine-wide slots, so when other sessions or worktrees on the same box are already running heavy work, yours prints "all N machine-wide slots are busy; queueing" and then stays quiet until a slot frees. Give the command a long timeout and let it wait rather than killing it, retrying it, or assuming it hung. Don't change the # of machine-wide slots or make it unlimited by setting `LITELLM_GATE_SLOTS=0`
If you're trying to create a new function that relies on untyped stuff, instead of adding more Any's and pushing `reportAny` / `reportExplicitAny` closer to their basedpyright ceilings, just validate it in the caller with Pydantic (a model or `TypeAdapter` that returns the typed thing or raises will do) and then pass the now typed variable in
If you get an LIT001 or LIT002 fail, refactor the code to follow functional programming best practices rather than introducing mutable data structures. For example, build values in one shot with comprehensions or generators wrapped in `tuple()` / `MappingProxyType()` / `frozenset()` instead of seeding an empty `list`/`dict`/`set` and mutating it over time. Ideally, `# mutable-ok` is never used; reach for it only as a genuine last resort when an immutable rewrite is truly impossible, and always pair it with a real reason
@ -83,7 +85,8 @@ Follow these coding conventions for new/updated code (a three-line fix in a lega
- Never-nester: early returns over deep nesting
- Don't throw; model failures as values (One function (e.g., raise_public) maps error union to existing public exception contracts via exhaustive match + assert_never)
- No mutation; don't reassign variables, global or local. Instead of mutable lists and dicts, prefer tuples, frozen dataclasses (with slots=True), `MappingProxyType`, etc.
- Annotate every variable with `: Final` (LIT010). Unpacking and walrus targets cannot carry the annotation, so they are implicitly final. Don't rebind them. Never rebind or mutate function parameters (LIT011); `self`/`cls` attribute stores are the exception. If rebinding or in-place mutation is truly unavoidable, suppress with `# rebind-ok: <reason>` explaining why

- Use dependency injection
- Fully typed; no `Any` or coarse types like `dict[str, Any]` or just `dict`. Every function parameter must be strongly typed
- Use tagged unions + match

`tests/test_litellm` holds thousands of tests, so running all of it locally takes a long time. CI runs it as a parallel matrix (`make test-unit-llms`, `make test-unit-proxy-core`, and the other `test-unit-*` targets) on beefier boxes, so if, for whatever reason, you must run the whole suite, it's better to rely on CI to do that.
