STATE | ACTIONS
|
=========================================================================
ERROR | Clean up resources used to serve clients.
| Always remain in ERROR state.
-------------------------------------------------------------------------
INITIAL | Connect to the pipe asynchronously.
| If connection is successfully queued up asynchronously,
| go into CONNECTING state.
| If connection is done synchronously, go into CONNECTED
| state.
| For any unexpected problems, go into ERROR state.
-------------------------------------------------------------------------
CONNECTING | Get the result of async connection request.
| If I/O is still incomplete, remain in the CONNECTING
| state.
| If connection is complete, go into CONNECTED state.
| For any unexpected problems, go into DISCONNECTING state.
-------------------------------------------------------------------------
CONNECTED | Read from the pipe asynchronously.
| If read request is successfully queued up asynchronously,
| go into READING state.
| For any unexpected problems, go into DISCONNECTING state.
-------------------------------------------------------------------------
READING | Get the result of async read request.
| If read is done, go into READ_DONE state.
| For any unexpected problems, go into DISCONNECTING state.
-------------------------------------------------------------------------
READ_DONE | Register the client, prepare the reply and write the
| reply to the pipe asynchronously.
| If write request is successfully queued up asynchronously,
| go into WRITING state.
| For any unexpected problems, go into DISCONNECTING state.
-------------------------------------------------------------------------
WRITING | Get the result of the async write request.
| If write is done, go into WRITE_DONE state.
| For any unexpected problems, go into DISCONNECTING state.
-------------------------------------------------------------------------
WRITE_DONE | Read from the pipe asynchronously (for an ACK).
| If read request is successfully queued up asynchonously,
| go into READING_ACK state.
| For any unexpected problems, go into DISCONNECTING state.
-------------------------------------------------------------------------
READING_ACK | Get the result of the async read request.
| If read is done, perform action for successful client
| connection.
| Go into DISCONNECTING state.
-------------------------------------------------------------------------
DISCONNECTING | Disconnect from the pipe, reset the event and go into
| INITIAL state and signal the event again. If anything
| fails, go into ERROR state.
