How to bypass the warning when running 'rake sunspot:solr:reindex'?

[Drew Sheneman]

I am trying to deploy Sunspot Solr to a server using a Capistrano in my RoR application. I have a task to reindex:

  desc "reindex the whole database"
  task :reindex, :roles => :app do
    stop
    run "rm -rf #{shared_path}/solr/data"
    start
    run "cd #{current_path} && RAILS_ENV=#{rails_env} bundle exec rake sunspot:solr:reindex"
  end

When Capistrano tries to execute this task I get the warning:

  * executing "cd /home/username/apps/appname/current && RAILS_ENV=production bundle exec rake sunspot:solr:reindex"
    servers: ["0.0.0.0"]
    [10.0.63.19] executing command
 ** [out :: 0.0.0.0] *Note: the reindex task will remove your current indexes and start from scratch.
 ** [out :: 0.0.0.0]
 ** [out :: 0.0.0.0] If you have a large dataset, reindexing can take a very long time, possibly weeks.
 ** [out :: 0.0.0.0]
 ** [out :: 0.0.0.0] This is not encouraged if you have anywhere near or over 1 million rows.
 ** [out :: 0.0.0.0]
 ** [out :: 0.0.0.0] Are you sure you want to drop your indexes and completely reindex? (y/n)
 ** [out :: 0.0.0.0]

The task just hangs at this point and cannot complete. I have been searching for ways to bypass this warning, however haven't found any surprisingly. Any help is appreciated.

First things first, report this to the solr developers, they shouldn't be prompting for input unless stdin is a tty.

And then change your task to be:

  desc "reindex the whole database"
  task :reindex, :roles => :app do
    stop
    run "rm -rf #{shared_path}/solr/data"
    start

    run "cd #{current_path} && yes | RAILS_ENV=#{rails_env} bundle exec rake sunspot:solr:reindex"
  end

Note the addition of `yes |` this should echo "y" onto std in forever (thus it'll say yes to any program that asks for input) - if that doesn't work, you can also do `echo myanswer | RAILS_ENV.............` (echo something specific) - if neither of those things work solr is too badly behaved and you'll have to resort to `gnu expect` but that's almost certainly going to make you very, very unhappy.

Your first suggestion worked like a charm. Saved me lots of frustration. Thanks!
