Installation

Add this line to your application's Gemfile:

And then execute:

$ bundle

Or install it yourself as:

$ gem install capistrano-file-transfer-ext

Usage

Add require line in your Capfile or config/deploy.rb or so.

require "capistrano/configuration/actions/file_transfer_ext"

Now you can use them in your tasks.

  • safe_put - Store the contents of multiple servers. (more...)
  • transfer_if_modified - Transfer files from/to remote servers only if they are different. (more...)
  • install - Install files on remote servers. (more...)
  • install_if_modified - Install files on remote servers only if they are different. (more...)

Reference

safe_upload

Definition

safe_upload(from, to, options={}, &block)

Module

Capistrano::Configuration::Actions::FileTransferExt

The safe_upload acts like almost as same as upload, but with some little enhancements.

  1. overwrite remote file only if transmission has been successfully completed.
  2. (if you request) overwrite remote file only if the checksums are different.

Arguments

from

Thie may be either a String, or an IO object (e.g. an open file handle, or a StringIO instance).

to

This must be a string indicating the path on the remote server that should be uploaded to.

options

All of the options of upload are sensible. In addition, there are some extra options.

  • :install It must be either :always (the default), or :if_modified. If :if_modified is given, install the file only if the checksums are different.
  • :digest This is a symbol indicating which algorithm should be used to calculate the checksum of files. :md5 is default.
  • :digest_cmd The command to calculate checksum of files. md5sum is default.
  • :run_method specify the method to run commands. :run by default. you may need to set this value as :sudo if you want to overwrite system files.

safe_put

Definition

safe_put(data, to, options={})

Module

Capistrano::Configuration::Actions::FileTransferExt

The safe_put action is safe_upload's little brother.

Arguments

data

This is a string containing the contents of the file you want to upload.

to

This is a string naming the file on the remote server(s) that should be created (or overwritten) with the given data.

options

All of the options of safe_upload are sensible.

transfer_if_modified

Definition

transfer_if_modified(direction, from, to, options={}, &block)

Module

Capistrano::Configuration::Actions::FileTransferExt

The transfer_if_modified action is transfer's senior brother. Transfer files from/to remote servers only if they are different.

Arguments

direction

The direction of transfer. :up or :down is sensible.

from

Thie may be either a String, or an IO object (e.g. an open file handle, or a StringIO instance).

to

This must be a string indicating the path on the remote server that should be uploaded to.

options

All of the options of transfer are sensible. In addition, there are some extra options.

  • :digest This is a symbol indicating which algorithm should be used to calculate the checksum of files. :md5 is default.
  • :digest_cmd The command to calculate checksum of files. md5sum is default.

install

Definition

install(from, to, options={}, &block)

Module

Capistrano::Configuration::Actions::FileTransferExt

Install files on remote servers. This method acts like mv, but with little enhancements.

Arguments

from

This must be a string indicating the path on the remote server that should be installed from.

to

This must be a string indicating the path on the remote server that should be installed to.

options

  • :via specify the method to run commands. :run by default. you may need to set this value as :sudo if you want to overwrite system files.
  • :mode The mode of destination file. If :preserve is given, preserve original mode of to.
  • :owner The owner of destination file. If :preserve is given and :via is :sudo, preserve original owner of to.
  • :group The group of destination file. If :preserve is given and :via is :sudo, preserve original group of to.

install_if_modified

Definition

install_if_modified(from, to, options={}, &block)

Module

Capistrano::Configuration::Actions::FileTransferExt

The install_if_modified action is install's senior brother. Install files on remote servers only if they are different.

Arguments

from

This must be a string indicating the path on the remote server that should be installed from.

to

This must be a string indicating the path on the remote server that should be installed to.

options

  • :via specify the method to run commands. :run by default. you may need to set this value as :sudo if you want to overwrite system files.

  • :owner The owner of destination file. If not given and :via is :sudo, preserve original owner of to.
  • :group The group of destination file. If not given and :via is :sudo, preserve original group of to.
  • :digest This is a symbol indicating which algorithm should be used to calculate the checksum of files. :md5 is default.
