Assets compiling on redeploy

[mrrooijen]

I tried to deploy the same codebase multiple times without commit changes but it seems it keeps recompiling the assets.

According to:

• http://nadarei.co/mina/tasks/rails_assets_precompile.html
• https://github.com/nadarei/mina/blob/master/lib/mina/rails.rb#L50

it should not re-compile if no changes took place.

Can you check it manually? All that does is run a diff on those folders:

      diff -r "#{current_path}/vendor/assets/" "./vendor/assets/" 2>/dev/null
      diff -r "#{current_path}/app/assets/" "./app/assets/" 2>/dev/null

try running those commands manually and see what happens.

I have the same issue. Here's the resulting script piece (obtained with -S):

 ) && (

    # Check if the last deploy has assets built, and if it can be re-used.
    if [ -d "current/public/assets" ]; then
      count=`(
        diff -r "current/vendor/assets/" "./vendor/assets/" 2>/dev/null;
        diff -r "current/app/assets/" "./app/assets/" 2>/dev/null
      ) | wc -l`

      if [ "$((count))" = "0" ]; then
        echo "-----> Skipping asset precompilation"
        cp -R "current/public/assets" "./public/assets" &&
        exit
      fi
    fi

    echo "-----> Precompiling asset files"
    RAILS_ENV="production" bundle exec rake assets:precompile

  )

It seems that current_path is equal to "current" which is obviously wrong.

@rstacruz running those commands yields nothing. There is no output.

Okay, gonna fix this up in a while. While I'm at it, I'll do the same optimization for db_migrate.
