Prevent queue method to display output

[jmuheim]

I have Rollbar exception tracking enabled for my project.

I want to notify Rollbar when I have deployed a new version. This can be done with the following code:

desc "Notifies rollbar."
task :notify_rollbar do
  revision = `git log -n 1 --pretty=format:"%H"`
  local_user = `whoami`
  rollbar_token = '???' # TODO: Store rollbar token at one single place!
  rails_env = 'production'
  queue "curl https://api.rollbar.com/api/1/deploy/ -F access_token=#{rollbar_token} -F environment=#{rails_env} -F revision=#{revision} -F local_username=#{local_user} >/dev/null 2>&1"
end

I then do a invoke :'notify_rollbar' before the to :launch do ... end block.

This works well, but the output from the CURL command is displayed during deployment:

-----> DB migrations unchanged; skipping DB migration        
-----> Skipping asset precompilation        
       % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
       Dload  Upload   Total   Spent    Left  Speed
109   549    0    16  106   533     21    711 --:--:-- --:--:-- --:--:--  2123    0
       { 
         "data": {} 
       }-----> Build finished 
-----> Moving build to releases/35        
-----> Updating the current symlink 

This is nasty. Is there a way to prevent this?

you can try adding this to your curl call:

-s, --silent
Silent or quiet mode. Don't show progress meter or error messages. Makes Curl mute. It will still output the data you ask for, potentially even to the terminal/stdout unless you redirect it.

It seems that adding this option somehow makes the thing fail.

queue "curl https://api.rollbar.com/api/1/deploy/ -F access_token=#{rollbar_token} -F environment=#{rails_env} -F revision=#{revision} -F local_username=#{local_user} --silent >/dev/null 2>&1"

Output when deploying:

-----> Skipping asset precompilation        
       % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
       Dload  Upload   Total   Spent    Left  Speed
109   549    0    16  106   533     20    679 --:--:-- --:--:-- --:--:--  2011    0
       { 
         "data": {} 
       }! ERROR: Deploy failed.

Sorry, this is a curl bug/problem and not mina. There is nothing more we can do for you :(
