Bug #969: EOFError when doing net/http post with large body
http://redmine.ruby-lang.org/issues/show/969

Author: Timothy Elliott
Status: Open, Priority: Normal

Official Ruby 1.8.7-i386-mswin32 binary.

Running Windows Vista SP1 64-bit.

When performing an HTTP post using net/http, and a body under 23,400 bytes, I get a response from the server. When over 23,500 bytes, I get the following error:

C:\Users\tim\Desktop\ruby\bin>ruby ../../cr.rb
C:/Users/tim/Desktop/ruby/lib/ruby/1.8/uri.rb:16: warning: already initialized constant VERSION_CODE

        from C:/Users/tim/Desktop/ruby/lib/ruby/1.8/net/http.rb:543:in `start'
        from ../../cr.rb:11

The above error message is triggered with the following script:

require 'URI'
require 'net/http'

body_string = 'a' * 23500
url = 'http://google.com'

uri = URI.parse url
http = Net::HTTP.new uri.host, uri.port
req = Net::HTTP::Post.new uri.request_uri
req.body = body_string
response = http.start{|conn| conn.request req} 
puts response.body
