'EOFError: end of file reached' on HEROKU while posting UTF-8 via SSL

Question

I've got strange bug on heroku. To reproduce it I have to make big (over few KB) HTTPS POST with any UTF-8 characters in request body. Here is an example:

require "net/https"
require "uri"

#Accutally I've ecountered this bug while posting to another server
url = URI.parse("https://api.heroku.com/myapps")

#It's Ukrainian 'oiced velar plosive G' letter
payload = "ґ"*10000
request = Net::HTTP::Post.new(url.path)
request.body = payload
http = Net::HTTP.new(url.host, url.port)
http.use_ssl = true
http.read_timeout = 500
http.start {|http| http.request request }

Running such script on local machine's irb gives me:

#<Net::HTTPUnauthorized 401 Unauthorized readbody=true> 

...which is expected, but on heroku cedar, runing it on 'heroku console' ... in about 60sec I get:

EOFError: end of file reached
    from /usr/local/lib/ruby/1.9.1/openssl/buffering.rb:145:in `sysread_nonblock'
    from /usr/local/lib/ruby/1.9.1/openssl/buffering.rb:145:in `read_nonblock'

    from /app/vendor/bundle/ruby/1.9.1/gems/railties-3.2.7/lib/rails/commands.rb:41:in `<top (required)>'

What should I do with it?

Answer 1

I had to add ruby version into Gemfile, as default Cedar's ruby is 1.9.2(which has bug passing UTF-8 strings over SSL)

source 'https://rubygems.org'
ruby "1.9.3"

gem 'rails', '3.2.7'
gem 'pg'
...

I think, this should works:

require "net/https"
require "uri"

url = URI.parse("https://api.heroku.com/myapps")
#It's Ukrainian letter 'soft-G'
payload = "ґ"*10000
request = Net::HTTP::Post.new(url.path)
request.basic_auth 'youremail', 'yourpassword'
request.body = URI.encode(payload)
http = Net::HTTP.new(url.host, url.port)
http.use_ssl = true
http.read_timeout = 500
http.start {|http| http.request request }
