Errno::EPIPE: Broken pipe

[kris-at-tout]

gem version: 1.1.5

I have the following method (for reproducing)

require 'net/http/post/multipart'

def submit_file
  f = './lib/qa_monitoring/video_source/test.mp4'
  uri = URI.parse('https://api.tout.com/api/v1/touts')
  header = {"Authorization"=>"Bearer some_api_token", "Connection"=>"keep-alive",       "Accept"=>"application/json"}
  File.open(f) do |video|
    req = Net::HTTP::Post::Multipart.new(uri.path,
      {"file" => UploadIO.new(video, 'video/mp4', "video.mp4")},
      header)
    res = Net::HTTP.start(uri.host, uri.port) do |http|
      http.request(req)
    end
  end
  res
end

When I run this in irb, I get the following exception:

Errno::EPIPE: Broken pipe from /Users/kris/.rvm/rubies/ruby-1.9.3-p362/lib/ruby/1.9.1/net/protocol.rb:199:in write' from /Users/kris/.rvm/rubies/ruby-1.9.3-p362/lib/ruby/1.9.1/net/protocol.rb:199:inwrite0' from /Users/kris/.rvm/rubies/ruby-1.9.3-p362/lib/ruby/1.9.1/net/protocol.rb:173:in block in write' from /Users/kris/.rvm/rubies/ruby-1.9.3-p362/lib/ruby/1.9.1/net/protocol.rb:190:inwriting' from /Users/kris/.rvm/rubies/ruby-1.9.3-p362/lib/ruby/1.9.1/net/protocol.rb:172:in write' from /Users/kris/.rvm/rubies/ruby-1.9.3-p362/lib/ruby/1.9.1/net/http.rb:1955:insend_request_with_body_stream' from /Users/kris/.rvm/rubies/ruby-1.9.3-p362/lib/ruby/1.9.1/net/http.rb:1921:in exec' from /Users/kris/.rvm/rubies/ruby-1.9.3-p362/lib/ruby/1.9.1/net/http.rb:1317:inblock in transport_request' from /Users/kris/.rvm/rubies/ruby-1.9.3-p362/lib/ruby/1.9.1/net/http.rb:1316:in catch' from /Users/kris/.rvm/rubies/ruby-1.9.3-p362/lib/ruby/1.9.1/net/http.rb:1316:intransport_request' from /Users/kris/.rvm/rubies/ruby-1.9.3-p362/lib/ruby/1.9.1/net/http.rb:1293:in request' from (irb):12:inblock (2 levels) in submit_file' from /Users/kris/.rvm/rubies/ruby-1.9.3-p362/lib/ruby/1.9.1/net/http.rb:745:in start' from /Users/kris/.rvm/rubies/ruby-1.9.3-p362/lib/ruby/1.9.1/net/http.rb:557:instart' from (irb):11:in block in submit_file' from (irb):7:inopen' from (irb):7:in `submit_file'

With the correct token, I can upload the same file via a REST client.

Hi @kris-at-tout, I'm getting the same error from a very similar snippet of code on the latest version of multipart-post. Did you ever manage to resolve this issue? Is there a workaround or something?

I get this error after switching from HTTP to SSL.

I figured out how to solve my issue, which I also commented at https://github.com/nicksieger/multipart-post/issues/18

For me this was a HTTPS issue.

I split up the Net::HTTP.start method into two:

1. my_request = Net::HTTP.new (which takes the same options as Net::HTTP.start)
2. add the my_request.use_ssl = true option here (before starting the request)
3. my_request.start { |http| ... etc }

Is this an issue with multipart-post or a general issue wiht usage of NET::HTTP? Can we close this?
