LineageOS Updater Backend

Adding a new device

1. Add your device to devices.json, sorted alphanumerically by codename. Fields are documented below.
2. Submit your change to gerrit (this repository is configured for use with git review)

devices.json

devices.json is an array of objects, each with several fields:

• model: should be the first thing on the line, and is the device's codename (PRODUCT_DEVICE) - e.g. i9300.
• oem: the manufacturer of the device. (PRODUCT_BRAND) - e.g. Samsung.
• name: the user-friendly name of the device - e.g. Galaxy S III (Intl). Long values will overflow and look bad, so limit this to around 25 characters.
• has_recovery: (optional) whether or not the device has a separate recovery partition. Defaults to true.
• lineage_recovery: (optional) whether or not to offer Lineage recovery downloads for this device. Defaults to true.

Development set up:

1. Install requirements with pip install -r requirements.txt
2. Configure your environment appropriately - see config.py for possible variables.
3. Supply a device_deps.json, devices.json, and optional devices_local.json. (See https://github.com/LineageOS/hudson/tree/main/updater for example)
4. Run with FLASK_APP=app.py flask run

Example API Calls:

Obtaining rom list for a device:
GET /api/v1/<device>/<romtype>/<incremental>?after=<utc_timestamp>&version=<14.1> (incremental can be anything, it is currently unused)
<device> - Name of device. Example: d2vzw
<romtype> - Type of rom. Example: nightly
<incremental> - Caller device's incremental ID (ro.build.incr). Can be anything.
<after> - Timestamp for current build on device. (optional)
<romversion> - Version of rom. Example: 14.1(optional)

This project depends on a mirrorbits server (https://github.com/etix/mirrorbits) running our mirrorbits API (https://github.com/lineageos-infra/mirrorbits-api). Please see the README in that project for more information.

Don't want to run mirrorbits/mirrorbits-api?

To run the server stand-alone you can use the included docker-compose script to bring up a simple nginx server to host your builds for you.

Setup

1. Place your builds in ./nginx/builds/. These will be exposed on http://example.com/builds when you start the server. They don't need to be android builds, just make sure they have differing sha256s and match the filename format foobar-VERSION-BUILDDATE-BUILDTYPE-DEVICE-foobar.zip.
2. Run python gen_mirror_json.py ./nginx/builds > ./nginx/builds.json
3. Make sure you have device_deps.json, devices.json, and optional devices_local.json in the root directory of this repo.
4. Install docker-compose on your system.
5. Make sure that docker-compose.yml and ./nginx/default.conf use suitable hostnames for your setup (rather than "updater" and "nginx", you should use the address of the computer running docker).

Building and Running

1. To build, use docker-compose build in the root of the repo.
2. To start the server, run docker-compose up in the root of the repo (include a -d flag to run in detached mode)
3. To stop the server, run docker-compose down in the root of the repo.
