- Move recurring tasks into their own class; inherits from `FeatherTask` - CCS proposals: Don't use API, it's broken - webcrawl instead until it is fixed. - Switch to hypercorn as the ASGI server, *with* support for multiple workers. You can now run feather-ws with, for example, `--workers 6`. See `Dockerfile`. - Introduce support for various coins under `BlockheightTask` - Introduce support for various Reddit communities under `RedditTask` - Introduced weightvoting whilst validating third-party RPC blockheights - where nodes are filtered based on what other nodes are commonly reporting. - Current blockheights are fetched from various block explorers and weightvoting is done to eliminate outliers under `BlockheightTask`. - Don't filter/remove bad nodes from the rpc_nodes list; correctly label them as disabled/bad nodes. - Multiple Feather instances (each for it's own coin) can now run on one machine, using only one Redis instance, as each coins has it's own Redis database index. - Configuration options inside `settings.py` can now be controlled via environment variables. - Better logging through custom log formatting and correct usage of `app.logger.*` - Fixed a bug where one task could overlap with itself if the previous one did not finish yet. This was particularly noticable inside the `RPCNodeCheckTask` where the high timeout (for Tor nodes) could cause the task to run *longer* than the recurring task interval. - Introduced a `docker-compose.yml` to combine the Feather container with Redis and Tor containers. - Blocking IO operations are now done via `aiofiles`

Back-end websocket server for Feather wallet.
|
|
|
|
- Quart web framework, Py3 asyncio
|
|
- Redis
|
|
|
|
## Coins supported
|
|
|
|
- Monero
|
|
- Wownero
|
|
|
|
See also the environment variables `FEATHER_COIN_NAME`, `FEATHER_COIN_SYMBOL`, etc. in `settings.py`.
|
|
|
|
## Tasks
|
|
|
|
This websocket server has several scheduled recurring tasks:
|
|
|
|
- Fetch latest blockheight from various block explorers
|
|
- Fetch crypto/fiat exchange rates
|
|
- Fetch latest Reddit posts
|
|
- Fetch funding proposals
|
|
- Check status of RPC nodes (`data/nodes.json`)
|
|
|
|
When Feather wallet starts up, it will connect to
|
|
this websocket server and receive the information
|
|
listed above which is necessary for normal operation.
|
|
|
|
See `fapi.tasks.*` for the various tasks.
|
|
|
|
## Development
|
|
|
|
Requires Python 3.7 and higher.
|
|
|
|
```
|
|
virtualenv -p /usr/bin/python3 venv
|
|
source venv/bin/activate
|
|
pip install -r requirements.txt
|
|
|
|
export FEATHER_DEBUG=true
|
|
python run.py
|
|
```
|
|
|
|
Note that `run.py` is meant as a development server. For production,
|
|
use `asgi.py` with something like hypercorn.
|
|
|
|
## Docker
|
|
|
|
In production you may run via docker;
|
|
|
|
```
|
|
docker-compose up
|
|
```
|
|
|
|
Will bind on `http://127.0.0.1:1337`. Modify `docker-compose.yml` if necessary.
