'''
This package tunnels the Corpus Query interface (CQi) protocol through
Socket.IO (SIO) by wrapping each CQi function in a seperate SIO event.
This module only handles the SIO connect/disconnect, which handles the setup
and teardown of necessary ressources for later use. Each CQi function has a
corresponding SIO event. The event handlers are spread across the different
modules within this package.
Basic concept:
1. A client connects to the SIO namespace and provides the id of a corpus to be
analysed.
1.1 The analysis session counter of the corpus is incremented.
1.2 A CQiClient and a (Mutex) Lock belonging to it is created.
1.3 Wait until the CQP server is running.
1.4 Connect the CQiClient to the server.
1.5 Save the CQiClient and the Lock in the session for subsequential use.
2. A client emits an event and may provide a single json object with necessary
arguments for the targeted CQi function.
3. A SIO event handler (decorated with cqi_over_socketio) gets executed.
- The event handler function defines all arguments. Hence the client
is sent as a single json object, the decorator decomposes it to fit
the functions signature. This also includes type checking and proper
use of the lock (acquire/release) mechanism.
4. Wait for more events
5. The client disconnects from the SIO namespace
1.1 The analysis session counter of the corpus is decremented.
1.2 The CQiClient and (Mutex) Lock belonging to it are teared down.
