We write to a socket when we've already shutdown() the write side. * On Windows the error returned for this is ESHUTDOWN * rather than EPIPE. * 2. The TCP peer sends us an RST through no fault of our own (perhaps * by aborting the connection using SO_LINGER) and we then attempt * to write to the socket. On Linux and Windows we would actually * receive an ECONNRESET error for this, but on the BSDs, Darwin, * Illumos and presumably Solaris, it's an EPIPE. * 3. We cause the TCP peer to send us an RST by writing to a socket * after we receive a FIN from them. Our first write will be * successful, but if the they have closed the connection (rather * than just shutting down the write side of it) this will cause their * OS to send us an RST. Then, when we attempt to write to the socket * a second time, we will get an EPIPE error. On Windows we get an * ECONNABORTED. * * What we are going to do here is to treat all EPIPE messages that aren't * of type 1 as ECONNRESET errors. This will allow users who have the * show_econnreset socket option enabled to receive {error, econnreset} on * both send and recv operations to indicate that an RST * has been received. */ #ifdef __WIN_32__ // <= if (err == ECONNABORTED) err = ECONNRESET; #endif if (err == EPIPE && !(desc->tcp_add_flags & TCP_ADDF_SHUTDOWN_WR_DONE)) err = ECONNRESET; return tcp_send_or_shutdown_error(desc, err); }
