Timer id conversion keeps objects alive for a certain amount of time after their last access. The default time period is 600 seconds and can be changed upon initialization.

To use TimerIdConv:

DRb.install_id_conv TimerIdConv.new 60 # one minute

A custom InputMethod class used by XMP for evaluating string io.

HTTPGenericRequest is the parent of the Net::HTTPRequest class. Do not use this directly; use a subclass of Net::HTTPRequest.

Mixes in the Net::HTTPHeader module to provide easier access to HTTP headers.

WriteTimeout, a subclass of Timeout::Error, is raised if a chunk of the response cannot be written within the write_timeout. Not raised on Windows.

The writer adapter class

Rinda error base class

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]

RingFinger is used by RingServer clients to discover the RingServer’s TupleSpace. Typically, all a client needs to do is call RingFinger.primary to retrieve the remote TupleSpace, which it can then begin using.

To find the first available remote TupleSpace:

Rinda::RingFinger.primary

To create a RingFinger that broadcasts to a custom list:

rf = Rinda::RingFinger.new  ['localhost', '192.0.2.1']
rf.primary

Rinda::RingFinger also understands multicast addresses and sets them up properly. This allows you to run multiple RingServers on the same host:

rf = Rinda::RingFinger.new ['239.0.0.1']
rf.primary

You can set the hop count (or TTL) for multicast searches using multicast_hops.

If you use IPv6 multicast you may need to set both an address and the outbound interface index:

rf = Rinda::RingFinger.new ['ff02::1']
rf.multicast_interface = 1
rf.primary

At this time there is no easy way to get an interface index by name.

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].

An error that indicates we weren’t able to fetch some data from a source

Represents an error communicating via HTTP.

Raised by Gem::Validator when something is not right in a gem.

A Source knows how to list and fetch gems from a RubyGems marshal index.

There are other Source subclasses for installed gems, local gems, the bundler dependency API and so-forth.

The SourceList represents the sources rubygems has been configured to use. A source may be created from an array of sources:

Gem::SourceList.from %w[https://rubygems.example https://internal.example]

Or by adding them:

sources = Gem::SourceList.new
sources << 'https://rubygems.example'

The most common way to get a SourceList is Gem.sources.

ConditionVariable objects augment class Mutex. Using condition variables, it is possible to suspend while in the middle of a critical section until a resource becomes available.

Example:

mutex = Thread::Mutex.new
resource = Thread::ConditionVariable.new

a = Thread.new {
   mutex.synchronize {
     # Thread 'a' now needs the resource
     resource.wait(mutex)
     # 'a' can now have the resource
   }
}

b = Thread.new {
   mutex.synchronize {
     # Thread 'b' has finished using the resource
     resource.signal
   }
}

OpenSSL IO buffering mix-in module.

This module allows an OpenSSL::SSL::SSLSocket to behave like an IO.

You typically won’t use this module directly, you can see it implemented in OpenSSL::SSL::SSLSocket.
