Debugging the issue some I can say that (for me) the issue seems to be
when the server sends the answer response to the client. It is running
in "ply_boot_connection_send_answer" when it gets a SIGPIPE in the
middle, implying the client has gone:
ply_boot_connection_send_answer()
{
[...]
if (!ply_write (connection->fd,
PLY_BOOT_PROTOCOL_RESPONSE_TYPE_ANSWER,
strlen (PLY_BOOT_PROTOCOL_RESPONSE_TYPE_ANSWER)) ||
!ply_write_uint32 (connection->fd,
size) ||
!ply_write (connection->fd,
answer, size))
ply_trace ("could not finish writing answer: %m");
[...]
Now the client does wait for the server to respond before exiting
blocking until the user hits return, and it reports a failure was sent.
This however could come out for a lost connection also. The fact that
it does wait hints that the response triggers the closure. Need more
debug as to what if anything is received.
