Compliance

sonic.websocket uses the autobahn-testsuite to validate the WebSocket implementation. sonic.websocket implements most of the WebSocket protocol with the exception of:

• DEFLATE compression
• UTF8 handling.

Notes

There are two state machines that combined form a stateful WebSocket parser.

• FrameCodec handles the state of a frame where the smallest unit is a byte.
• WebsocketStream handles the state of the whole stream where the smallest unit is a frame. WebsocketStream uses FrameCodec.
