I've taken out some transitions for simplicity (eg. ERR_ANCHOR_LOST and
ERR_INFORMATION_LEAK, which shouldn't happen):
Normal opening states:
INIT_NOANCHOR:
INPUT_NONE -> OPEN_WAIT_FOR_OPEN_NOANCHOR (=>PKT_OPEN)
INIT_WITHANCHOR:
INPUT_NONE -> OPEN_WAIT_FOR_OPEN_WITHANCHOR (=>PKT_OPEN)
OPEN_WAIT_FOR_OPEN_NOANCHOR:
PKT_OPEN -> OPEN_WAIT_FOR_ANCHOR
CMD_CLOSE -> CLOSED
OPEN_WAIT_FOR_OPEN_WITHANCHOR:
PKT_OPEN -> OPEN_WAIT_FOR_COMMIT_SIG (=>PKT_OPEN_ANCHOR)
CMD_CLOSE -> CLOSED
OPEN_WAIT_FOR_ANCHOR:
PKT_OPEN_ANCHOR -> OPEN_WAITING_THEIRANCHOR (=>PKT_OPEN_COMMIT_SIG)
CMD_CLOSE -> CLOSED
OPEN_WAIT_FOR_COMMIT_SIG:
PKT_OPEN_COMMIT_SIG -> OPEN_WAITING_OURANCHOR
CMD_CLOSE -> CLOSED
OPEN_WAITING_OURANCHOR:
PKT_CLOSE -> WAIT_FOR_CLOSE_ACK (=>PKT_CLOSE_COMPLETE)
BITCOIN_ANCHOR_DEPTHOK -> OPEN_WAIT_FOR_COMPLETE_OURANCHOR (=>PKT_OPEN_COMPLETE)
BITCOIN_ANCHOR_THEIRSPEND -> CLOSE_WAIT_SPENDTHEM (=>PKT_ERROR)
CMD_CLOSE -> WAIT_FOR_CLOSE_COMPLETE (=>PKT_CLOSE)
OPEN_WAITING_THEIRANCHOR:
PKT_CLOSE -> WAIT_FOR_CLOSE_ACK (=>PKT_CLOSE_COMPLETE)
PKT_ERROR -> CLOSE_WAIT_OURCOMMIT
BITCOIN_ANCHOR_DEPTHOK -> OPEN_WAIT_FOR_COMPLETE_THEIRANCHOR (=>PKT_OPEN_COMPLETE)
BITCOIN_ANCHOR_TIMEOUT -> ERR_ANCHOR_TIMEOUT (=>PKT_ERROR)
BITCOIN_ANCHOR_THEIRSPEND -> CLOSE_WAIT_SPENDTHEM (=>PKT_ERROR)
CMD_CLOSE -> WAIT_FOR_CLOSE_COMPLETE (=>PKT_CLOSE)
OPEN_WAIT_FOR_COMPLETE_OURANCHOR:
PKT_OPEN_COMPLETE -> NORMAL_HIGHPRIO
PKT_CLOSE -> WAIT_FOR_CLOSE_ACK (=>PKT_CLOSE_COMPLETE)
PKT_ERROR -> CLOSE_WAIT_OURCOMMIT
BITCOIN_ANCHOR_THEIRSPEND -> CLOSE_WAIT_SPENDTHEM (=>PKT_ERROR)
CMD_CLOSE -> WAIT_FOR_CLOSE_COMPLETE (=>PKT_CLOSE)
OPEN_WAIT_FOR_COMPLETE_THEIRANCHOR:
PKT_OPEN_COMPLETE -> NORMAL_LOWPRIO
PKT_CLOSE -> WAIT_FOR_CLOSE_ACK (=>PKT_CLOSE_COMPLETE)
PKT_ERROR -> CLOSE_WAIT_OURCOMMIT
BITCOIN_ANCHOR_THEIRSPEND -> CLOSE_WAIT_SPENDTHEM (=>PKT_ERROR)
CMD_CLOSE -> WAIT_FOR_CLOSE_COMPLETE (=>PKT_CLOSE)
Operational state loop:
