hosts filtering not working

[RobinClowers]

I seem to have hit a bug with hosts filtering. I have a pretty simple setup with 2 servers, and when I try to deploy to only one (either with HOSTS=hostname or --hosts=hostname) I get an error about a release directory not existing on the other host.

Hi guys, I have same issue. @RobinClowers did you solve it somehow?

[epifanov]

@RobinClowers do you use Rails? It could be rails specific problem: capistrano/rails#87

[RobinClowers]

No, I didn't solve it. I am using rails, but I had the same issue with a custom task, so I don't think it's rails specific.

@RobinClowers I checked sources of capistrano-rails gem and found this: https://github.com/capistrano/rails/blob/master/lib/capistrano/tasks/migrations.rake#L7

It means that it searches primary servers with db role, so I added "primary:true" key in my deploy.rb config and it helped.

Hi, I came across the same issue on v3.3+.

It seems that it was supposed to ignore host filter?
https://github.com/capistrano/capistrano/blob/master/spec/integration/dsl_spec.rb#L106-L107

I added a hack in my capistrano plugin:

# Usage: 
# set_host_filter ['example1.com']
def set_host_filter hosts
  if defined? Capistrano::Configuration::Servers::HostFilter
    set :filter, hosts: hosts
  else
    # hack for Capistrano v3.3+
    Capistrano::Configuration.env.send(:servers).send(:servers).select! do |srv|
      hosts.include?(srv.hostname)
    end
  end
end

I think one can allow host filtering via command line by fixing Capistrano::Configuration::Servers#roles_for. I did but it broke some specs, so I gave up.

Is this still an issue in latest Capistrano? I use the hosts feature all the time and it works for me.
