# Match Audio Filter

## What causes this lambda to run?

The match-audio state machine kicks off this lambda to determine if it should continue to run for the specified asset.

## What does this lambda do?

1. Using `ASSET_FINAL_ID`, call GraphQL to look up vendor information.
2. Use the vendor info to call split.io to check the `content_review` flag setting.
3. Return a dict containing the resolution of the split.io call.

## Usage

### Install

To install a development environment, you can run:

```sh
make pip_dev
```

### Requirements

- python3.11

Direct dependencies are listed in `requirements-to-freeze.txt` and locked with
their own dependencies in `requirements.txt`. `requirements.txt` is imported into
`requirements-test.txt` and testing dependencies are listed. To bump versions
of dependencies, update the version in `requirements-to-freeze.txt` and run
the command below to regenerate `requirements.txt`.

```sh
make pip_lock_versions
```

### Development

```sh
# Run the function locally using a test event and print results
make dev

# Run linting
make lint

# Run tests
make test

# Build the docker image, launch it, and run linting and tests against it
make docker_test

# Rebuild your local env from scratch
make clean dev
```

## Docker Stack

The docker stack offers an environment like the one on AWS for developing against.

```sh
# Bring the function up in a docker-compose stack. The container will mount
# src dir so it will update immediately as you develop.
make docker_up

# Send a mock event to the function
make docker_event

# Bring the stack down
make docker_down
```

> Note that this requires docker to be running locally and for you to grant docker
> permission to access your local directory.
