From: Matthew Johnson Date: 2011-11-03T10:16:43+09:00 Subject: [ruby-core:40696] [Ruby 1.8 - Bug #5557][Open] ftp error uploading binary files Issue #5557 has been reported by Matthew Johnson. ---------------------------------------- Bug #5557: ftp error uploading binary files http://redmine.ruby-lang.org/issues/5557 Author: Matthew Johnson Status: Open Priority: Normal Assignee: Category: Target version: ruby -v: ruby 1.8.7 (2010-01-10 patchlevel 249) [universal-darwin11.0] I have a build script which uploads resulting zip files to a Dreamhost account using net/ftp. It used to work fine and no longer works. I have verified on a few machines that it appears to work fine on my Macs which have patch level 174 (Snow Leopard), but not on my Macs which have patch level 249 (both Snow Leopard and Lion). All Macs are on 1.8.7 so it appears that the patch level is where the break happened. Here is a sample representing the kind of code that I have in my script (I have obviously taken out the actual domain, username, password, etc). require 'net/ftp' Net::FTP.open "ftp.mysite.com" do |ftp| ftp.login "...", "..." ftp.chdir "mybuilds" ftp.putbinaryfile "myfile.zip" end Here is the stack trace I get: Errno::EINVAL: Invalid argument method write in ftp.rb at line 456 method storbinary in ftp.rb at line 456 method loop in ftp.rb at line 453 method storbinary in ftp.rb at line 453 method synchronize in monitor.rb at line 242 method storbinary in ftp.rb at line 450 method putbinaryfile in ftp.rb at line 562 method upload in build.rb at line 67 method build in build.rb at line 86 method run_builds in build.rb at line 127 method each in build.rb at line 102 method run_builds in build.rb at line 102 at top level in build.rb at line 168 method open in ftp.rb at line 115 at top level in build.rb at line 165 -- http://redmine.ruby-lang.org
