Capistrano is a utility for executing commands in parallel on multiple machines, such as for automating the deployment of applications. Version 1.4.0 is now available.
To install:gem install capistrano
Version 1.4.0 fixes a few bugs, and adds a few features. The new features:
- A “capture” helper has been added, to make it easy to capture the stdout of a remote command and return it as a string:
- A “get” helper has been added, to mirror the “put” command, letting you easily download files from a remote server to the local host. It will only download from the first server that matches the criteria for the current task. You must have Net::SFTP installed (gem install net-sftp) in order to use the “get” helper.
- Support for a system-wide config file has been added. If a file exists in “/etc/capistrano.conf”, it will be loaded immediately after the standard recipe file is loaded, and immediately before any user-specific configuration.
The fixed bugs:
- There used to be issues with cap hanging when running multiple capistrano instances at the same time when using gateways. This has been fixed.
- The permissions tweaking in the standard recipe has been refactored into a separate task (set_permissions), which you can override if you are on a host that won’t let you set group-writable permissions.
- The setup task now uses umask so that intermediate directories are created with the proper permissions.
- Make sure the standard recipe loads first, so that .caprc and friends can oerride what it defines.
- cold_deploy now calls update instead of deploy, to avoid invoking the restart task.
- The ‘touch’ command in update_code now sets TZ to UTC for the duration of that command, so that asset timestamps are set correctly.
- An off-by-one bug in the width computation for show_tasks has been fixed.
c/-caprc switch has been removed, since the new load order (standard, system, user, application) makes it meaningless.
