Capistrano : apply local patches when deploying from an external source code repository

jnewland (Jesse Newland) — Wed, 13 Dec 2006 20:51:35 GMT

I've submitted patches to a couple rails apps, and want to run off of their SCM's trunk code, but with my local patches applied. These Capistrano tasks will take any files matching

patches/*.diff

in your local directory, and apply them before restarting your app.



task :after_setup do

  patches_setup

end



task :after_update_code do

  send_and_apply_patches

end



task :patches_setup do

  run "mkdir -p #{deploy_to}/#{shared_dir}/patches" 

end



task :send_and_apply_patches do

  Dir[File.join(File.dirname(__FILE__), '../patches/*.diff')].sort.each do |patch|

    puts "sending #{File.basename(patch)}"

    put(File.read(patch),

       "#{deploy_to}/#{shared_dir}/patches/#{File.basename(patch)}",

       :mode => 0777)

    puts "applying #{File.basename(patch)}"

    run "cd #{release_path}; patch -p0 < #{deploy_to}/#{shared_dir}/patches/#{File.basename(patch)}"

  end

end
