Templates are used to match tuples in Rinda.

Documentation?

An SimpleRenewer allows a TupleSpace to check if a TupleEntry is still alive.

A RingServer allows a Rinda::TupleSpace to be located via UDP broadcasts. Default service location uses the following steps:

1. A RingServer begins listening on the network broadcast UDP address.

2. A RingFinger sends a UDP packet containing the DRb URI where it will listen for a reply.

3. The RingServer receives the UDP packet and connects back to the provided DRb URI with the DRb service.

A RingServer requires a TupleSpace:

ts = Rinda::TupleSpace.new
rs = Rinda::RingServer.new

RingServer can also listen on multicast addresses for announcements. This allows multiple RingServers to run on the same host. To use network broadcast and multicast:

ts = Rinda::TupleSpace.new
rs = Rinda::RingServer.new ts, %w[Socket::INADDR_ANY, 239.0.0.1 ff02::1]

RingProvider uses a RingServer advertised TupleSpace as a name service. TupleSpace clients can register themselves with the remote TupleSpace and look up other provided services via the remote TupleSpace.

Services are registered with a tuple of the format [:name, klass, DRbObject, description].

A TemplateEntry is a Template together with expiry and cancellation data.

Documentation?

A NotifyTemplateEntry is returned by TupleSpace#notify and is notified of TupleSpace changes. You may receive either your subscribed event or the ‘close’ event when iterating over notifications.

See TupleSpace#notify_event for valid notification types.

Example

ts = Rinda::TupleSpace.new
observer = ts.notify 'write', [nil]

Thread.start do
  observer.each { |t| p t }
end

3.times { |i| ts.write [i] }

Outputs:

['write', [0]]
['write', [1]]
['write', [2]]

Run an instance of the gem program.

Gem::GemRunner is only intended for internal use by RubyGems itself. It does not form any public API and may change at any time for any reason.

If you would like to duplicate functionality of ‘gem` commands, use the classes they call directly.

Gem::Server and allows users to serve gems for consumption by ‘gem –remote-install`.

gem_server starts an HTTP server on the given port and serves the following:

• “/” - Browsing of gem spec files for installed gems

• “/specs.#{Gem.marshal_version}.gz” - specs name/version/platform index

• “/latest_specs.#{Gem.marshal_version}.gz” - latest specs name/version/platform index

• “/quick/” - Individual gemspecs

• “/gems” - Direct access to download the installable gems

• “/rdoc?q=” - Search for installed rdoc documentation

Usage

gem_server = Gem::Server.new Gem.dir, 8089, false
gem_server.run

RefError is raised when a referenced object has been recycled by the garbage collector

An HTTP Proxy server which proxies GET, HEAD and POST requests.

To create a simple proxy server:

require 'webrick'
require 'webrick/httpproxy'

proxy = WEBrick::HTTPProxyServer.new Port: 8000

trap 'INT'  do proxy.shutdown end
trap 'TERM' do proxy.shutdown end

proxy.start

See ::new for proxy-specific configuration items.

Modifying proxied responses

To modify content the proxy server returns use the :ProxyContentHandler option:

handler = proc do |req, res|
  if res['content-type'] == 'text/plain' then
    res.body << "\nThis content was proxied!\n"
  end
end

proxy =
  WEBrick::HTTPProxyServer.new Port: 8000, ProxyContentHandler: handler

An HTTP Server

Base server class

Base TCP server class. You must subclass GenericServer and provide a run method.

This module has all methods of FileUtils module, but it outputs messages before acting. This equates to passing the :verbose flag to methods in FileUtils.

Logging severity.

Mixin for HTTP and FTP URIs.
