The flow:
 
POST a form to braintree with customer details (our payment forms do this)
Braintree redirects to a URL we provided in the form
On this URL we ask braintree to confirm the result they give us
We create a customer
We set up the charges (different per payment plan)
 
The problem:
 
We POST the form to braintree, and a local sinatra app picks that up (from fake_braintree which has a sinatra app that emulates the braintree service)
Fake braintree redirects to the the right url
We start the confirm request...and it hangs
 
I modified the fake_braintree sinatra app to do some logging, to ensure requests were hitting it:
 
# Braintree::TransparentRedirect.url
    post "/merchants/:merchant_id/transparent_redirect_requests" do
      Braintree::Configuration.logger.debug "REDIRECT REQUEST: #{params}"
 
The log shows:
 
REDIRECT REQUEST: {"utf8"=>"✓", "tr_data"=>"742a2d545019733686164b83dd925e486bae12b8|api_version=3&customer%5Bemail%5D=email0%40email.com&customer%5Bid%5D=1&kind=create_customer&public_key=xxx&redirect_url=http%3A%2F%2F127.0.0.1%3A54281%2Fre%2Fusers%2Fpay&time=20121214151439", "customer"=>{"first_name"=>"Scarlett", "last_name"=>"Pimpernell", "credit_card"=>{"billing_address"=>{"street_address"=>"1 Here", "extended_address"=>"There", "locality"=>"San Francisco", "region"=>"California", "postal_code"=>"11111"}, "number"=>"4111111111111111", "expiration_date"=>"12/15", "cvv"=>"111"}}, "commit"=>"Pay", "splat"=>[], "captures"=>["xxx"], "merchant_id"=>"xxx"}
 
So this hits the app fine, and clearly redirects correctly because our rails app is hit on the correct url. Log:
 
Started GET "/re/users/pay?http_status=200&id=a92dea503ed7b2e94e80e7a5745d1472&kind=create_customer&hash=18881831a344369481e26970dcc0d9ec0fcae76a" for 127.0.0.1 at 2012-12-14 15:27:11 +0000

At this stage it hangs, and times out.

The sinatra app was modified to look like so:

# Braintree::TransparentRedirect.confirm
    post "/merchants/:merchant_id/transparent_redirect_requests/:id/confirm" do
      Braintree::Configuration.logger.debug "CONFIRMING #{params}"

It never gets to this part while the test is running, but as soon as it times out. Low and behold! the sinatra log shows:

CONFIRMING {"splat"=>[], "captures"=>["xxx", "a92dea503ed7b2e94e80e7a5745d1472"], "merchant_id"=>"xxx", "id"=>"a92dea503ed7b2e94e80e7a5745d1472"}

However my tests shows:

Timeout::Error (Timeout::Error):
  app/controllers/registrations_controller.rb:38:in `payment'
 
No idea why, the app is running and acccepting requests (I used HTTP Client to test it was).

W.T.F.
