Can not get it to work (using JRuby 1.7.10 and Savon 2.3.0) #549

fjyaniez · 2014-02-11T16:39:39Z

I'm triying to use Savon to check if an european VAT is valid without success:

Does it work for any of you?

@fjyaniez I just installed jruby-1.7.9 and this seems to work fine:

It looks like I'm using Wasabi v3.2.2 locally, so maybe I'll bump that and upgrade to jruby 1.7.10 and see how it works.

fjyaniez · 2014-02-13T21:25:56Z

Hi @tjarratt

I'm also using Wasabi 3.2.2. If you could try using jruby 1.7.10 it would be great :) Thanks!

tjarratt · 2014-02-14T03:38:40Z

@fjyaniez I'm sad to report that I was able to use Savon v2.3.3 on jruby 1.7.10 with Wasabi v3.2.3 without any issue.

Would you mind attaching a gist of the WSDL your client is getting? I would probably use an http client like httparty to fetch the document before your client tries to call #operations

eg:

require 'httparty'
puts "WSDL is #{HTTParty.Get('http://ec.europa.eu/taxation_customs/vies/checkVatService.wsdl')}.inspect"
client = Savon.client(wsdl: "http://ec.europa.eu/taxation_customs/vies/checkVatService.wsdl")
puts client.operations.inspect

Relevant output from my irb session:

± bundle exec irb
jruby-1.7.10 :001 > RUBY_VERSION
 => "1.9.3" 
jruby-1.7.10 :002 > require 'savon'

Hi,

I found a difference in my setup, I'm using ruby 2.0.0 compatibility:

I'm going to check with 1.9.3 and let you know... thanks!

fjyaniez · 2014-02-14T09:48:34Z

And I can confirm the problem is using JRuby in ruby 2.0.0 mode.

tjarratt · 2014-02-14T17:23:29Z

Oh, great, thanks for providing that debug information @fjyaniez! It looks like the bug is in Wasabi under Jruby 2.0.0 mode then. I'll keep this open until savonrb/wasabi#42 is fixed.

fjyaniez · 2014-02-14T18:19:54Z

Thank you so much @tjarratt

tjarratt · 2014-03-06T07:10:55Z

Good news -- I've finally found a reproducible testcase for this issue. I've heard grumbles about this bug from a few other people, so I'm hoping to find a resolution this week.

tjarratt · 2014-03-06T07:33:14Z

Curious -- on my machine it looks like it's failing because the XML passed to nokogiri is an empty string. It seems to work if you fetch the wsdl separately and then pass it to savon. Does that match what you're seeing, @fjyaniez?

require 'savon'

wsdl = File.read("path/to/checkVatService.wsdl")
client = Savon.client(wsdl: wsdl)
client.operations # [:check_vat, :check_vat_approx] SUCCESS

tjarratt · 2014-03-07T06:20:39Z

Narrowed this down a bit further to the httpi gem. Apparently making a GET request with jruby 1.7.10 to this URL returns an empty response body. Looping in @rogerleite -- maybe he has some insight into why this is happening?

Shell

export JRUBY_OPTS=--2.0

Gemfile

source 'https://rubygems.org'

ruby '2.0.0', engine: 'jruby', engine_version: '1.7.10'
gem 'savon', '~> 2.3.2'

test.rb

require 'httpi'
HTTPI.get("http://ec.europa.eu/taxation_customs/vies/checkVatService.wsdl")

Making a request with HTTParty, curl or Net::HTTP works, however.

rogerleite · 2014-03-07T12:19:12Z

Using JRuby the response body is empty.
I didn't find the problem, for now, the only weird thing that i found was response headers:

MRI 1.9.3
[4] pry(main)> response.headers
=> {"Date"=>"Fri, 07 Mar 2014 12:08:15 GMT",
 "Accept-Ranges"=>"none",
 "Content-Length"=>"10201",
 "Last-Modified"=>"Fri, 28 Jun 2013 20:27:21 GMT",
 "Server"=>"Europa",
 "Proxy-Connection"=>"Keep-Alive",
 "Connection"=>"Keep-Alive"}

JRuby 1.7.10
[1] pry(main)> response
=> #<HTTPI::Response:0x42d0a46b
 @code=200,
 @headers=
  {"date"=>"Fri, 07 Mar 2014 12:09:26 GMT",
   "accept-ranges"=>"none",
   "last-modified"=>"Fri, 28 Jun 2013 20:27:21 GMT",
   "server"=>"Europa",
   "transfer-encoding"=>"chunked",
   "proxy-connection"=>"Keep-Alive",
   "connection"=>"Keep-Alive"},

I think the problem is related to Transfer-Encoding "chunked". If this works on HTTParty, the next step is to discover what magic it does. I'll try to look at this on afternoon.

rogerleite · 2014-03-26T10:53:42Z

Ok. I quit. I can't find out what is going on ... somebody have some idea?

tjarratt · 2014-03-26T16:38:09Z

@rogerleite I appreciate all of the hard work you put in trying to debug this problem, as well as your honesty.

I was looking at this last night and it occurred to me that this error is very likely the same error that is causing our builds to fail on travis-ci. Will investigate more this week and see if I can track down the culprit.

tjarratt · 2014-04-02T19:52:14Z

@fjyaniez I think I found the root cause of the problem -- it's embarrassingly obvious in retrospect.

Net::HTTP is the default adapter for HTTPI. In JRuby 1.7, when using the ruby 2.0 engine, inflating compressed responses sometimes return an empty string. This is fairly easy to reproduce:

require 'net/http'

Net::HTTP.get("ec.europa.eu", "/taxation_customs/vies/checkVatService.wsdl")

The issue tracking this in the JRuby repo is jruby/jruby#1216 and it looks like it was just reported as fixed two hours ago.

fjyaniez · 2014-04-02T19:53:29Z

Great, thanks for your time and letting me know @tjarratt

rogerleite · 2014-04-02T20:00:41Z

I'd never find this bug ... i swear that i saw this working on httparty.
Anyway, thanks @tjarratt for let us know!

tjarratt · 2014-04-02T20:29:47Z

@rogerleite -- to be fair, I led you astray. I implied that Net::HTTP worked, but it doesn't actually. It seems likely that HTTParty implements their own response parser, but I haven't actually investigated to see why HTTParty works but Net::HTTP doesn't.
