## Overview

Autosubmit API is a package that consumes the information generated by Autosubmit and serves it as an API.

Distribution: https://pypi.org/project/autosubmit-api/

See the wiki for documentation.

## Autosubmit Big Picture

![Autosubmit Big Picture](/docs/Total_Autosubmit_Diagram.png)

In this image you can see the flow of information in the **Autosubmit environment**.

* **Autosubmit**: Machines running Autosubmit.
* **Remote Platforms**: Platforms (HPCs in most cases) to which Autosubmit connects to run jobs. 
* **Experiment Database**: Starting from Autosubmit `3.13.0`, each experiment generates a set of databases that save important (reusable) information about it. We have the `historical database`, `graph database`, `structures database`.
* **File System**: The file system where the experiment files are stored.
* **Data Process Workers**: **Autosubmit API** implements a set of workers that periodically collect information from the experiments or complement that information. In the current **BSC** implementation, these workers are running no `bscesweb04` under `webadmin` user.
* **Main Database**: **Autosubmit API** uses a centralized database to keep track of important experiment information. The **workers** fill this information. **Autosubmit** also writes into this database.
* **Autosubmit API**: See [Autosubmit API](https://earth.bsc.es/gitlab/es/autosubmit_api). Currently, under **BSC** implementation, this API is running on `bscesweb04` under `webadmin` user. This API exposes a set of requests that **Autosubmit GUI** consumes and serves to the users through the front end.
* **Autosubmit GUI**: This project.
* **Authentication Server**: **BSC Central Authentication Service**.
* **Users**: Users that access the GUI through their web browsers from any device. The current implementation requires that an user generates a token using the Authentication server once every 5 days.


## Installation

Autosubmit API can be easily installed via pip

```sh
pip install autosubmit-api # >=4.0 (recommended)

# Check installation and serving options
autosubmit_api start -h
```

Start the server:

```sh
autosubmit_api start
```

## Configuration options

The Autosubmit API have some configuration options that can be modified by setting their specific environment variable before starting the server:

* **`PROTECTION_LEVEL`**: Default `ALL`. Possible values `ALL`, `WRITEONLY`, `NONE`.
    * If set to `ALL`, all the endpoints will be protected by needing a valid token inside the `Authorization` header of the request.
    * If set to `WRITEONLY`, only a subset of the endpoints will be protected.
    * If set to `NONE`, none of the endpoints will be protected.
* **`SECRET_KEY`**: The secret key to encode the JWT tokens from the Authorization Module. **Important to be set up on production.**
* **`CAS_LOGIN_URL`**: CAS Protocol URL to request a ticket.
* **`CAS_VERIFY_URL`**: CAS Protocol URL to verify a given ticket.


## How to run tests

### Install pytest

pip install -U pytest pytest-cov
```

### Run tests:

```bash
pytest tests/*
```

### Run tests with coverage HTML report:
