Module AWS::S3::Connection::Management::ClassMethods
In: lib/aws/s3/connection.rb

Manage the creation and destruction of connections for AWS::S3::Base and its subclasses. Connections are created with establish_connection!.


Public Instance methods

Returns true if a connection has been made yet.


     # File lib/aws/s3/connection.rb, line 175
175:           def connected?
176:             !connections.empty?
177:           end

Returns the connection for the current class, or Base’s default connection if the current class does not have its own connection.

If not connection has been established yet, NoConnectionEstablished will be raised.


     # File lib/aws/s3/connection.rb, line 166
166:           def connection
167:             if connected?
168:               connections[connection_name] || default_connection
169:             else
170:               raise NoConnectionEstablished
171:             end
172:           end

Removes the connection for the current class. If there is no connection for the current class, the default connection will be removed.


     # File lib/aws/s3/connection.rb, line 181
181:           def disconnect(name = connection_name)
182:             name       = default_connection unless connections.has_key?(name)
183:             connection = connections[name]
184:             connection.http.finish if connection.persistent?
185:             connections.delete(name)
186:           end

Clears all connections, from all classes, with prejudice.


     # File lib/aws/s3/connection.rb, line 189
189:           def disconnect!
190:             connections.each_key {|connection| disconnect(connection)}
191:           end

Creates a new connection with which to make requests to the S3 servers for the calling class.

  AWS::S3::Base.establish_connection!(:access_key_id => '...', :secret_access_key => '...')

You can set connections for every subclass of AWS::S3::Base. Once the initial connection is made on Base, all subsequent connections will inherit whatever values you don’t specify explictly. This allows you to customize details of the connection, such as what server the requests are made to, by just specifying one option.

  AWS::S3::Bucket.established_connection!(:use_ssl => true)

The Bucket connection would inherit the :access_key_id and the :secret_access_key from Base’s connection. Unlike the Base connection, all Bucket requests would be made over SSL.

Required arguments

  • :access_key_id - The access key id for your S3 account. Provided by Amazon.
  • :secret_access_key - The secret access key for your S3 account. Provided by Amazon.

If any of these required arguments is missing, a MissingAccessKey exception will be raised.

Optional arguments

  • :server - The server to make requests to. You can use this to specify your bucket in the subdomain,

or your own domain’s cname if you are using virtual hosted buckets. Defaults to

  • :port - The port to the requests should be made on. Defaults to 80 or 443 if the :use_ssl

argument is set.

  • :use_ssl - Whether requests should be made over SSL. If set to true, the :port argument

will be implicitly set to 443, unless specified otherwise. Defaults to false.

  • :persistent - Whether to use a persistent connection to the server. Having this on provides around a two fold

performance increase but for long running processes some firewalls may find the long lived connection suspicious and close the connection. If you run into connection errors, try setting :persistent to false. Defaults to true.


     # File lib/aws/s3/connection.rb, line 155
155:           def establish_connection!(options = {})
156:             # After you've already established the default connection, just specify 
157:             # the difference for subsequent connections
158:             options = default_connection.options.merge(options) if connected?
159:             connections[connection_name] = Connection.connect(options)
160:           end
