Hoping to document issue and fix for the next poor sob. Owner luislavena commented Feb 16, 2013 @nekpractice can you provide more details against which version of MySQL you had issues connecting to? There is no real_connect method in this gem, at least not in Ruby (the code is in C) Can you reproduce mysql error code this with a bare/plain connection of mysql gem and MySQL server? can you provide those details? Thank you. nekpractice commented Feb 16, 2013 I'm not much of a Ruby, C or GIT person. iirc, it was either or both MySQL 5.1 / 5.5 Supposedly this was fixed somewhere (MySQL 5.6?), but I don't remember just where / what version of what. I don't fully understand the question / request. So, here is the mysql.rb in full (without the patch - original version). (real_connect is the second method defined, right after the first one - initialize) (I don't know why some of the comments appear here as large and bold font, in particular the first 3 lines of a sharp, space, and then the comment text.): # $Id: mysql.rb,v 1.24 2005/02/12 11:37:15 tommy Exp $ # # Copyright (C) 2003-2005 TOMITA Masahiro # tommy@tmtm.org # class Mysql VERSION = "4.0-ruby-0.2.6-plus-changes" require "socket" require "digest/sha1" MAX_PACKET_LENGTH = 256*256*256-1 MAX_ALLOWED_PACKET = 1024*1024*1024 MYSQL_UNIX_ADDR = "/tmp/mysql.sock" MYSQL_PORT = 3306 PROTOCOL_VERSION = 10 SCRAMBLE_LENGTH = 20 SCRAMBLE_LENGTH_323 = 8 # Command COM_SLEEP = 0 COM_QUIT = 1 COM_INIT_DB = 2 COM_QUERY = 3 COM_FIELD_LIST = 4 COM_CREATE_DB = 5 COM_DROP_DB = 6 COM_REFRESH = 7 COM_SHUTDOWN = 8 COM_STATISTICS = 9 COM_PROCESS_INFO = 10 COM_CONNECT = 11 COM_PROCESS_KILL = 12 COM_DEBUG = 13 COM_P
