class Elasticsearch::Transport::Transport::HTTP::Manticore

Alternative HTTP transport implementation for JRuby, using the [Manticore](github.com/cheald/manticore) client,

@example HTTP

   require 'elasticsearch/transport/transport/http/manticore'

   client = Elasticsearch::Client.new transport_class: Elasticsearch::Transport::Transport::HTTP::Manticore

   client.transport.connections.first.connection
   => #<Manticore::Client:0x56bf7ca6 ...>

   client.info['status']
   => 200

@example HTTPS (All SSL settings are optional,
                see http://www.rubydoc.info/gems/manticore/Manticore/Client:initialize)

   require 'elasticsearch/transport/transport/http/manticore'

   client = Elasticsearch::Client.new \
     url: 'https://elasticsearch.example.com',
     transport_class: Elasticsearch::Transport::Transport::HTTP::Manticore,
     ssl: {
       truststore: '/tmp/truststore.jks',
       truststore_password: 'password',
       keystore: '/tmp/keystore.jks',
       keystore_password: 'secret',
     }

   client.transport.connections.first.connection
   => #<Manticore::Client:0xdeadbeef ...>

   client.info['status']
   => 200

Public Instance Methods

__build_connections() click to toggle source

Builds and returns a collection of connections. Each connection is a Manticore::Client

@return [Connections::Collection]

# File lib/elasticsearch/transport/transport/http/manticore.rb, line 93
def __build_connections
  @request_options = {}

  if options[:transport_options] && options[:transport_options][:headers]
    @request_options[:headers] = options[:transport_options][:headers]
  end

  if options.key?(:headers)
    @request_options[:headers] = options[:headers]
  end

  Connections::Collection.new \
    :connections => hosts.map { |host|
      host[:protocol]   = host[:scheme] || DEFAULT_PROTOCOL
      host[:port]     ||= DEFAULT_PORT

      host.delete(:user)     # auth is not supported here.
      host.delete(:password) # use the headers

      Connections::Connection.new \
        :host => host,
        :connection => @manticore
    },
    :selector_class => options[:selector_class],
    :selector => options[:selector]
end
__close_connections() click to toggle source

Closes all connections by marking them as dead and closing the underlying HttpClient instances

@return [Connections::Collection]

# File lib/elasticsearch/transport/transport/http/manticore.rb, line 125
def __close_connections
  # The Manticore adapter uses a single long-lived instance
  # of Manticore::Client, so we don't close the connections.
end
build_client(options={}) click to toggle source

Should just be run once at startup

# File lib/elasticsearch/transport/transport/http/manticore.rb, line 54
def build_client(options={})
  client_options = options[:transport_options] || {}
  client_options[:ssl] = options[:ssl] || {}

  @manticore = ::Manticore::Client.new(client_options)
end
host_unreachable_exceptions() click to toggle source

Returns an array of implementation specific connection errors.

@return [Array]

# File lib/elasticsearch/transport/transport/http/manticore.rb, line 134
def host_unreachable_exceptions
  [
    ::Manticore::Timeout,
    ::Manticore::SocketException,
    ::Manticore::ClientProtocolException,
    ::Manticore::ResolutionFailure
  ]
end
perform_request(method, path, params={}, body=nil) click to toggle source

Performs the request by invoking {Transport::Base#perform_request} with a block.

@return [Response] @see Transport::Base#perform_request

# File lib/elasticsearch/transport/transport/http/manticore.rb, line 66
def perform_request(method, path, params={}, body=nil)
  super do |connection, url|
    params[:body] = __convert_to_json(body) if body
    params = params.merge @request_options
    case method
    when "GET"
      resp = connection.connection.get(url, params)
    when "HEAD"
      resp = connection.connection.head(url, params)
    when "PUT"
      resp = connection.connection.put(url, params)
    when "POST"
      resp = connection.connection.post(url, params)
    when "DELETE"
      resp = connection.connection.delete(url, params)
    else
      raise ArgumentError.new "Method #{method} not supported"
    end
    Response.new resp.code, resp.read_body, resp.headers
  end
