        This project intends to simplify the sysupgrade process of devices running
        OpenWrt or distributions based on the former like LibreMesh. The provided tools
        here offer an easy way to reflash the router with a new version or package
        upgrades, without the need of `opkg` installed.
        
        Additionally it offers an API (covered below) to request custom images with any
        selection of packages pre-installed, allowing to create firmware images without
        the need of setting up a build environment, even from mobile devices.
        
        ## Clients
        
        ### OpenWrt Firmware Selector
        
        Simple web interface using vanilla JavaScript currently developed by @mwarning.
        It offers a device search based on model names and show links either to
        [official images](https://downloads.openwrt.org/) or requests images via the
        *asu* API. Please join in the development at the [GitLab
        repository](https://gitlab.com/openwrt/web/firmware-selector-openwrt-org)

        ### LuCI app
        
        The package
        [`luci-app-attendedsysupgrade`](https://github.com/openwrt/luci/tree/master/applications/luci-app-attendedsysupgrade)
        offers a simple view under `System > Attended Sysupgrade` to automatically
        request a new firmware, wait until it's built and flash it.

        ### CLI
        
        It's possible to upgrade routers via a command line interface called
        [`auc`](https://github.com/openwrt/packages/tree/master/utils/auc).
        
        ![auc](misc/auc.png)
        
        ## Server
        
        The server listens to image requests and automatically generate them if the
        request was valid. This is done by automatically setting up OpenWrt
        ImageBuilders and cache images in a Redis database. This allows to quickly
        respond to requests without rebuilding existing images again.
        
        ### Active server
        
        *   [asu.aparcar.org](https://asu.aparcar.org)
        *   [chef.libremesh.org](https://chef.libremesh.org)
        
        ## Run your own server
        
        Redis is required to store image requests:
        
            sudo apt install redis-server tar
        
        Install *asu*:
        
            pip install asu
        
        Start the server via the following commands:
        
            export FLASK_APP=asu.asu  # set Flask app to asu
            flask janitor update      # download upstream profiles/packages
            flask run                 # run development server
        
        Start the worker via the following comand:
        
            rq worker
        
        ### Docker
        
        Run The service inside multiple Docker containers. The services include the
        *ASU* server itself, a *janitor* service which fills the Redis database with
        known packages and profiles as well as a `rqworker` which actually builds
        images.
        
        Currently all services share the same folder and therefore a very "open" access
        is required, suggestions on how to improve this setup are welcome.
        
        	mkdir ./asu-service/
        	chmod 777 ./asu-service/
        	docker-compose up
        
        A webserver should proxy API calls to port 8000 of the `server` service while
        the `asu/` folder should be file hosted as is.
        
        ### Production
        
        It is recommended to run *ASU* via `gunicorn` proxied by `nginx` or
        `caddyserver`. Find a possible server configurations in the `misc/` folder.
        
        The *ASU* server will try `$PWD/config.py` and `/etc/asu/config.py` to find a
        configuration. Find an example configuration in the `misc/` folder.
        
            pip install gunicorn
            gunicorn "asu.asu:create_app()"
        
        ### Development
        
        After cloning this repository create a Python virtual environment and install
        the dependencies:
        
            python3 -m venv .direnv
            source .direnv/bin/activate
            pip install -r requirements.txt
            export FLASK_APP=asu.asu  # set Flask app to asu
            export FLASK_DEBUG=1      # run Flask in debug mode (autoreload)
            flask run
        
        ## API
        
        The server does no longer offer complex upgrade check but only static JSON
        including available branches and versions. The client must evaluate itself if
        the responded JSON contains a newer version.
        
        ### Latest versions `/api/latest`
        
        The server responds with the latest versions of the same or newer branches. A
        client should always suggest the latest release of the same branch, however
        advanced users may also want to upgrade to a different branch. Branches are for
        instance `openwrt-18.06` and `openwrt-19.07`, where it is for a running 18.06.2
        device safer to upgrade to 18.06.7 than to 19.07.3.
        
        Snapshots are not shown in this list.
        
        ### Versions overview `/api/branches`
        
        Returns the configured branches. The content is based on the `BRANCHES`
        variable in the configuration, an example is available in `./misc/config.py`.
        
        ### Build request `/api/build`
        
        | key             | value                 | information                              |
        | --------------- | --------------------- | ---------------------------------------- |
        | `version`       | `SNAPSHOT`            | Requested version                        |
        | `target`        | `ath79/nand`          | Requested target                         |
        | `profile`       | `netgear_wndr4300-v2` | `board_name` of `ubus call system board` |
        | `packages`      | `["luci", "vim"]`     | Extra packages for the new image         |
        | `diff_packages` | `true`                | Install list of `packages` additionally to default packages or excklusively |
        
        Each valid request returns a `request_hash` which can be used for future
        polling via `/api/build/<request_hash>`.
        
        ### Response `status 200`
        
        A `200` response means the image was sucessfully created. The response is JSON
        encoded containing build information.
        
        | key            | information                                 |
        | -------------- | ------------------------------------------- |
        | `bin_dir`      | relative path to created files              |
        | `buildlog`     | boolean if buildlog.txt was created         |
        | `manifest`     | dict of all installed packages plus version |
        | `request_hash` | hashed request data stored by the server    |

        ### Response status codes
        
        The client should check the status code:
        
        | status | meaning                              | information                                                        |
        | ------ | ------------------------------------ | ------------------------------------------------------------------ |
        | `200`  | build finish / upgrade available     | see parameters above                                               |
        | `202`  | building, queued, imagebuilder setup | building right now or in build queue, contains `queue_position`    |
        | `400`  | bad request                          | see `error` parameter                                              |
        | `404`  | not found                            | if invalid `request_hash` supplied via `/api/build/<request_hash>` |
        | `422`  | unknown package                      | unknown package in request                                         |
        | `500`  | build failed                         | see `log` for build log                                            |
