wsc-grempy-transport 0.1.0

Supports gremlinpython without asyncio

This package helps you use gremlinpython, when you can't use asyncio.

Problem

In some settings, e.g. an eventlet web server with monkey patching, you may run into errors if you try to run code that relies on Python's asyncio framework. (Demonstration here.)

If you want to use gremlinpython in such a setting, then you need an alternative to the built-in AiohttpTransport class.

Solution

This package provides the WebsocketClientTransport class. It relies on the popular websocket-client package, which runs without asyncio.

Usage

from gremlin_python.driver.driver_remote_connection import DriverRemoteConnection
from wsc_grempy_transport.transport import websocket_client_transport_factory

remote = DriverRemoteConnection(
    'ws://localhost:8182/gremlin',
    transport_factory=websocket_client_transport_factory)

Development

The WebsocketClientTransport class is very rudimentary. It is essentially just a wrapper for the websocket.WebSocket class, and could probably benefit from some error checking to make it more robust.

Contributions are welcome!
