name: "Set up uv with retries"
description: >-
Install uv via astral-sh/setup-uv, retrying on transient failures. Even with
an exact pinned version, the action resolves the artifact URL by fetching
https://raw.githubusercontent.com/astral-sh/versions/main/v1/uv.ndjson in a
single request with no retry, timeout, or fallback, so one connection-level
network error ("fetch failed") fails the whole job before any test runs.
Retrying the full step covers the manifest fetch and the binary download.
Install uv via astral-sh/setup-uv, retrying the full setup step so manifest
resolution and binary downloads get fresh attempts after transient failures.

1. LLM response returns to `utils.py` wrapper after `litellm.acompletion()` completes
2. `update_response_metadata()` (`llm_response_utils/response_metadata.py`) is called
3. `logging_obj._response_cost_calculator()` (`litellm_logging.py`) calculates cost via `litellm.completion_cost()` (`cost_calculator.py`)
2. `update_response_metadata()` (`litellm_core_utils/llm_response_utils/response_metadata.py`) is called
3. `logging_obj._response_cost_calculator()` (`litellm_core_utils/litellm_logging.py`) calculates cost via `litellm.completion_cost()` (`cost_calculator.py`)
4. Cost is stored in `response._hidden_params["response_cost"]`
5. `proxy/common_request_processing.py` extracts cost from `hidden_params` and adds to response headers (`x-litellm-response-cost`)
6. `logging_obj.async_success_handler()` triggers callbacks including `_ProxyDBLogger.async_log_success_event()`

When you fix violations gated by `ruff-strict-budget.json`, `type-discipline-budget.json`, or `basedpyright-code-budget.json`, run `make lint-budget-update` and commit the lowered limits so the ceilings ratchet down instead of leaving stale headroom. It measures the working tree, so it must contain exactly the fixes you're committing
Never edit or commit `ruff-strict-budget.json`, `type-discipline-budget.json`, `basedpyright-code-budget.json`, or `test-quality-budget.json` on a PR branch, and don't run `make lint-budget-update` there. A scheduled Devin automation lowers the limits on the default branch in its own PR by exactly what landed since the last ratchet, so concurrent PRs don't fight over the same `"limit"` lines. Keep the hosted automation's target in sync when the repository default changes. If your branch already carries a budget edit, drop it before opening the PR
`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.

Local lint and budget checks follow origin's current default branch. They refresh it from the remote instead of trusting cached `origin/HEAD`. For an intentional comparison against another branch or commit, use `make check BASE_REF=<ref>` or the standalone gate's `--base <ref>` option. An explicit ref can also be used offline once it has been fetched locally. Without an override, unavailable remote metadata stops the check
## Submitting Your PR
1. **Push your branch**: `git push origin your-feature-branch`
2. **Create a PR**: Go to GitHub and open a pull request against [`litellm_internal_staging`](https://github.com/BerriAI/litellm/tree/litellm_internal_staging), which is the default base branch. Do not target `main`.
2. **Create a PR**: Go to GitHub and open a pull request against the repository's current default branch. Run `python3 scripts/default_branch.py --branch` to check its name
3. **Fill out the PR template**: Provide clear description of changes
4. **Wait for review**: Maintainers will review and provide feedback
5. **Address feedback**: Make requested changes and push updates

The Python ``prisma`` wrapper spawns Node, which spawns the Rust schema

no parent: it keeps mutating the database after the proxy has given up, holds
Prisma's advisory lock so every retry and every later boot queues behind it,
and dies mid-migration once its pipes close, leaving a half-applied ledger row.
Every Prisma command therefore runs in a process group of its own, and a
timeout kills the whole group.

## Branch Freshness Check
Before generating anything, `run_migration.py` runs `git fetch origin <base>` and refuses to proceed if `HEAD` is behind `origin/<base>`. Default base is `litellm_internal_staging` (the branch PRs target). A previous incident saw a stale branch silently drop production columns; freshness is the first-line defense.
Before generating anything, `run_migration.py` runs `git fetch origin <base>` and refuses to proceed if `HEAD` is behind `origin/<base>`. The default base is discovered from origin's advertised HEAD on each run, so an existing clone follows a default-branch change without trusting cached `origin/HEAD`. If discovery or fetching fails, migration generation stops. A previous incident saw a stale branch silently drop production columns; freshness is the first-line defense.
Flags:
- `--base-branch <name>` — check against a different base (e.g. `main`). Default is `litellm_internal_staging`.
- `--base-branch <name>` — check against a different base (e.g. a release branch). Defaults to origin's current default branch
- `--skip-freshness-check` — bypass entirely. Only for intentional migrations against an older base.

## Crates
| Crate | Role |

| litellm-core | The LiteLLM SDK in Rust. One public entrypoint per top-level call (`messages::messages()`), owning types, transforms, provider resolution, auth, and the provider HTTP call. Call it, get a typed response. |
| litellm-config | Config-loading boundary. Returns resolved core deployment data and optionally delegates loading to Python. |
| litellm-ai-gateway | The axum server (behind the `server` feature) plus the WebSocket hosts. Translates HTTP/WS to core entrypoints; owns no provider logic and no handlers. |
| litellm-python-interop | Domain-neutral PyO3 foundation for GIL handling and typed Python/Serde conversion. |
| litellm-python-bridge | PyO3 cdylib exposing LiteLLM Rust APIs to the Python SDK. Owns API registration, domain wiring, and Python exception mapping. |
Dependency direction is acyclic: `litellm-python-bridge` depends on the domain layers and `litellm-python-interop`; the interop foundation depends on no LiteLLM domain crate.

22. A Python -> Rust bridge keeps the Python side minimal: the Python interface only marshals inputs and calls the Rust interface, with no transform, handler, or business logic. Aim for well under 100 lines of interface code per route; if the Python grows past that, the logic belongs in Rust.
23. Do not bloat `litellm/main.py`. A route's provider dispatch lives in a thin dispatch class under `litellm/llms/<provider>/<route>/` that calls the Rust bridge; `main.py` only instantiates it and calls its sync/async method.
24. Do not add new feature flags unless explicitly requested. Reuse the existing litellm rust rollout mechanism (`use_litellm_rust`); never introduce a per-route env flag such as `LITELLM_USE_RUST_<ROUTE>`.

- **Request logs:** POSTed to a LiteLLM proxy at `/v1/rust_control_plane/logs` (see [Request logging](#request-logging))
> **Realtime serving is pure Rust.** Python is used at **load time only** — to
> read the config once at boot. The realtime hot path never touches Python.
The former `/health/gil` route and its acquisition counter were removed. They
only observed the single startup config load and did not prove that every GIL
acquisition was instrumented

# ai-gateway/src/python — Python interop (load-time only)
Functions here embed the Python interpreter (pyo3) and take the GIL to call into
`litellm` (e.g. read the proxy `model_list`). Compiled only under the
`python-config` feature.
## Hard rule: non-hot-path functions only
Everything in this folder MUST run **at most once per process lifetime — at
startup / load time** (config read, warm-up). NEVER call into Python on the
request path:
- No GIL acquisition per request, per connection, or per realtime event.
- No Python call inside a route handler, the router's hot path, or any loop that
scales with traffic.
**Why:** the GIL serializes execution and would cap throughput; the realtime data
path must stay pure Rust. Every acquisition is recorded by `crate::gil` — poll
`GET /health/gil`, and `total_acquisitions` MUST stay flat under load.
## How to add one
Resolve whatever Python-derived data you need **once at boot** and hand the rest
of the gateway an owned, plain-Rust value (e.g. build a `Router` from the
resolved `model_list`). Record the acquisition via `crate::gil::record_acquisition()`
immediately before taking the GIL. If a function would need to run per request,
it does not belong here — move the work to Rust, or pre-resolve it at startup.
