When running single queries using drizzle_query_add and
drizzle_query_run, occasionally drizzle_run_query returns
DRIZZLE_RETURN_NO_ACTIVE_CONNECTIONS. The cause is that if things are
timed correctly, the initial call to drizzle_query (query.c:219) returns
DRIZZLE_RETURN_OK, instead of DRIZZLE_RETURN_IO_WAIT. In this case, the
code needs to call drizzle_result_buffer. This gets complicated, because
it duplicates the code in the switch below.
I've added a patch to my branch. It is probably incorrect in some way,
but works for me. It moves the query state machine switch into its own
function. The initialization and the loop then both use this state
machine function.
