Capistrano deployment from svn failing - ruby-on-rails

Question

I am trying to use capistrano 2 to deploy my app from subversion to a local server. Here is the code I am trying to deploy, it is just the default rails app:
https://www.assembla.com/code/capistranotest/subversion/nodes
Here is the my deploy.rb file which points to my svn repo:
set :application, "CapistranoTest"
set :user, "jack"
set :repository, "https://subversion.assembla.com/svn/capistranotest/"
set :scm, :subversion
set :deploy_to, "/home/jaeren/capistranotest"
role :web, "192.168.169.129"
role :app, "192.168.169.129"
role :db, "192.168.169.129", :primary => true
set :scm_username, "jack"
set :runner, "jack"
set :use_sudo, false
My cap deploy:setup works and creates the necessary folders. However when I run cap deploy:cold and enter my username and password when prompted of my assembla account I get this error. Can anyone tell me why?

Tried changing to capistrano 2.12.0, it outputs different commands but I still get the same error:

Thanks.

Answer 1

Looks like it's trying to authenticate as jack--password because there's no space here between the value of username and the --password option that follows it.
executing locally: "svn info https://subversion.assembla.com/svn/capistranotest/ --username \"jack\"--password \"\"--no-auth-cache -rHEAD"
I suspect it's a bug in whatever is executing that command, which might be a built-in to Capistrano. Try upgrading to the latest Capistrano and then if that doesn't fix the issue, file a GitHub issue on the Capistrano project.

Answer 2

Ryan Bigg is correct. There is a bug in the SVN authentication task that Capistrano uses to login to the remote SVN repository.
I'm running Capistrano version 2.15.6 and the path to the file in question is at
capistrano-YOURVERSION/lib/capistrano/recipes/deploy/scm/subversion.rb
Open this file for editing and look for the authentication definition block towards the bottom.
def authentication
username = variable(:scm_username)
return "" unless username
result = %(--username "#{variable(:scm_username)}")
result << %(--password "#{variable(:scm_password)}") unless variable(:scm_auth_cache) || variable(:scm_prefer_prompt)
result << "--no-auth-cache " unless variable(:scm_auth_cache)
result
end
Notice the lack of white space where --password and --no-auth-cache are being concatenated to the result variable. I simply added a space in here
def authentication
username = variable(:scm_username)
return "" unless username
result = %(--username "#{variable(:scm_username)}")
result << %( --password "#{variable(:scm_password)}") unless variable(:scm_auth_cache) || variable(:scm_prefer_prompt)
result << " --no-auth-cache " unless variable(:scm_auth_cache)
result
end
It's possible that the OP isn't being prompted for SVN credentials when checking the repository out as they have saved the password against their SSH user. Capistrano accepts SCM credentials so it doesn't need to prompt the user for them during deployments. The reason why you're seeing a prompt to enter the details because with out the extra white space in the code above, it looks to the server as if Capistrano is trying to authenticate without sending a password.
