Issue: TCPSocketConnection::send_all(char* data, int length) bug
if connect is disconnect eth->send(...) will return 0, send_all(...) will loop but not return.
int ret = eth->send(_sock_fd, data + writtenLen, size);
-1 if unsuccessful, else number of bytes written int TCPSocketConnection::send_all(char* data, int length) { int writtenLen = 0;
if(_sock_fd<0) return -1;
while (writtenLen < length) {
if(!(eth->is_connected(_sock_fd))) return -1;
int size = eth->wait_writeable(_sock_fd, _blocking ? -1 : _timeout); if (size < 0) { return -1; } if (size > (length-writtenLen)) { size = (length-writtenLen); } int ret = eth->send(_sock_fd, data + writtenLen, size); if (ret < 0) { return -1; } writtenLen += ret; } return writtenLen; }
