Vagrant Reflect

Vagrant Reflect offers an extremely fast and highly optimised rsync-auto replacement for developers using Vagrant and Rsync with very large repositories.

$ vagrant reflect
==> default: Configuring rsync: /Users/Jason/Documents/Projects/vagrant-reflect/ => /vagrant
==> default:   - Exclude: [".git", "vendor", ".vagrant/"]
==> default: Doing an initial rsync...
==> default: Watching: /Users/Jason/Documents/Projects/vagrant-reflect
==> default: Sending change: /something
==> default: Synchronization completed
==> default: Sending change: /lib/something
==> default: Synchronization completed
==> default: Sending removal: /something
==> default: Synchronization completed
==> default: Sending removal: /lib/something
==> default: Synchronization completed

vagrant plugin install vagrant-reflect

Vagrant reflect will work with the usual rsync shared folder configurations and requires no further configuration.

However, there are a few vagrant-reflect specific options you can adjust that affect its behaviour. The available options and how to configure them is shown below.

NOTE: Currently, there is only a single option, show_sync_time.

Vagrant.configure('2') do |config|
    if Vagrant.has_plugin?("vagrant-reflect")
      # Show sync time next to messages
      # Default: false
      config.reflect.show_sync_time = true
    end
end

• Incremental transfer of file changes, accounting for the majority of a developers actions, instead of a full rsync of the entire folder. This will maintain server-side changes.
• Feedback on what and when is transferred
• Massively improved OS X performance by using a largely improved alpha version of guard/listen (see guard/listen#308 and driskell/listen)
• Unnecessary directory recursion is avoided reducing some common CPU usage issues
• Fixed a major issue which causes additions and modifications in the repository root to trigger an exponential recursive scan, hanging the process for minutes on large repositories
• Wrapped and released as driskell-listen for wider testing
• Improved support for rsync exclude strings so no unnecessary transfers are triggers

• Only tested on OS X - please feedback for other platforms!
• Symlinks can cause some strange behaviour in some instances due to incomplete implementations in both the improved guard/listen code and the incremental rsync
