Bug #46580 for IO: True value returned always on print to a socket

True value returned always on print to a socket

Hi, I am using IO-1.25 and Net::Stomp 0.34 (which actually uses IO::Socket::INET) to send messages to a message queue. I have hit a problem, in which that in Net::Stomp::send_frame, the message is 'print'ed to the socket, but that the return value is always true, even if the message_queue has gone away between making the socket connection and going to send the message. Is it possible that this could be fixed to throw an error (or at least return false) if the message can't be printed to the socket filehandle. I don't know if this is really an error with the print function in perl, but this is causing an issue with trying to operate a robust system, which would alert if it is unable to send the message to queue. Thanks for reading, and any help/fix that could be done. Cheers Andy

This is not an issue in IO. For ->print IO is nothing more than a thin veneer over perls print function. So you would get identical result with print $socket @args; If there is a bug, then it is in perl itself.

Hi Graham, Thanks for your speedy response. I did wonder if this might be the case, but didn't know if it was something that would be from IO, since the print is to the $socket 'filehandle'. Anyway, I am now working around it by testing the socket has a valid connection just before the print, so hopefully, errors will be minimised.
