Raised by Encoding and String methods when the string being transcoded contains a byte invalid for the either the source or target encoding.

Raised by transcoding methods when a named encoding does not correspond with a known converter.

File::Constants provides file-related constants. All possible file constants are listed in the documentation but they may not all be present on your platform.

If the underlying platform doesn’t define a constant the corresponding Ruby constant is not defined.

Your platform documentations (e.g. man open(2)) may describe more detailed information.

This module provides instance methods for a digest implementation object to calculate message digest values.

A DSL that provides the means to dynamically load libraries and build modules around them including calling extern functions within the C library that has been loaded.

Example

require 'fiddle'
require 'fiddle/import'

module LibSum
  extend Fiddle::Importer
  dlload './libsum.so'
  extern 'double sum(double*, int)'
  extern 'double split(double)'
end

Used to construct C classes (CUnion, CStruct, etc)

Fiddle::Importer#struct and Fiddle::Importer#union wrap this functionality in an easy-to-use manner.

exception to wait for reading. see IO.select.

Provides classes and methods to request, create and validate RFC3161-compliant timestamps. Request may be used to either create requests from scratch or to parse existing requests that again can be used to request timestamps from a timestamp server, e.g. via the net/http. The resulting timestamp response may be parsed using Response.

Please note that Response is read-only and immutable. To create a Response, an instance of Factory as well as a valid Request are needed.

Create a Response:

#Assumes ts.p12 is a PKCS#12-compatible file with a private key
#and a certificate that has an extended key usage of 'timeStamping'
p12 = OpenSSL::PKCS12.new(File.binread('ts.p12'), 'pwd')
md = OpenSSL::Digest.new('SHA1')
hash = md.digest(data) #some binary data to be timestamped
req = OpenSSL::Timestamp::Request.new
req.algorithm = 'SHA1'
req.message_imprint = hash
req.policy_id = "1.2.3.4.5"
req.nonce = 42
fac = OpenSSL::Timestamp::Factory.new
fac.gen_time = Time.now
fac.serial_number = 1
timestamp = fac.create_timestamp(p12.key, p12.certificate, req)

Verify a timestamp response:

#Assume we have a timestamp token in a file called ts.der
ts = OpenSSL::Timestamp::Response.new(File.binread('ts.der'))
#Assume we have the Request for this token in a file called req.der
req = OpenSSL::Timestamp::Request.new(File.binread('req.der'))
# Assume the associated root CA certificate is contained in a
# DER-encoded file named root.cer
root = OpenSSL::X509::Certificate.new(File.binread('root.cer'))
# get the necessary intermediate certificates, available in
# DER-encoded form in inter1.cer and inter2.cer
inter1 = OpenSSL::X509::Certificate.new(File.binread('inter1.cer'))
inter2 = OpenSSL::X509::Certificate.new(File.binread('inter2.cer'))
ts.verify(req, root, inter1, inter2) -> ts or raises an exception if validation fails

Socket::Constants provides socket-related constants. All possible socket constants are listed in the documentation but they may not all be present on your platform.

If the underlying platform doesn’t define a constant the corresponding Ruby constant is not defined.

Module managing the underlying network protocol(s) used by drb.

By default, drb uses the DRbTCPSocket protocol. Other protocols can be defined. A protocol must define the following class methods:

[open(uri, config)] Open a client connection to the server at +uri+,
                    using configuration +config+.  Return a protocol
                    instance for this connection.
[open_server(uri, config)] Open a server listening at +uri+,
                           using configuration +config+.  Return a
                           protocol instance for this listener.
[uri_option(uri, config)] Take a URI, possibly containing an option
                          component (e.g. a trailing '?param=val'),
                          and return a [uri, option] tuple.

All of these methods should raise a DRbBadScheme error if the URI does not identify the protocol they support (e.g. “druby:” for the standard Ruby protocol). This is how the DRbProtocol module, given a URI, determines which protocol implementation serves that protocol.

The protocol instance returned by open_server must have the following methods:

accept

Accept a new connection to the server. Returns a protocol instance capable of communicating with the client.

close

Close the server connection.

uri

Get the URI for this server.

The protocol instance returned by open must have the following methods:

send_request (ref, msg_id, arg, b)

Send a request to ref with the given message id and arguments. This is most easily implemented by calling DRbMessage.send_request, providing a stream that sits on top of the current protocol.

recv_reply

Receive a reply from the server and return it as a [success-boolean, reply-value] pair. This is most easily implemented by calling DRb.recv_reply, providing a stream that sits on top of the current protocol.

alive?

Is this connection still alive?

close

Close this connection.

The protocol instance returned by open_server().accept() must have the following methods:

recv_request

Receive a request from the client and return a [object, message, args, block] tuple. This is most easily implemented by calling DRbMessage.recv_request, providing a stream that sits on top of the current protocol.

send_reply(succ, result)

Send a reply to the client. This is most easily implemented by calling DRbMessage.send_reply, providing a stream that sits on top of the current protocol.

close

Close this connection.

A new protocol is registered with the DRbProtocol module using the add_protocol method.

For examples of other protocols, see DRbUNIXSocket in drb/unix.rb, and HTTP0 in sample/http0.rb and sample/http0serv.rb in the full drb distribution.

Mixin for HTTP and FTP URIs.

Random number formatter.

Formats generated random numbers in many manners.

Examples

Generate random hexadecimal strings:

require 'random/formatter'

prng.hex(10) #=> "52750b30ffbc7de3b362"
prng.hex(10) #=> "92b15d6c8dc4beb5f559"
prng.hex(13) #=> "39b290146bea6ce975c37cfc23"

Generate random base64 strings:

prng.base64(10) #=> "EcmTPZwWRAozdA=="
prng.base64(10) #=> "KO1nIU+p9DKxGg=="
prng.base64(12) #=> "7kJSM/MzBJI+75j8"

Generate random binary strings:

prng.random_bytes(10) #=> "\016\t{\370g\310pbr\301"
prng.random_bytes(10) #=> "\323U\030TO\234\357\020\a\337"

Generate alphanumeric strings:

prng.alphanumeric(10) #=> "S8baxMJnPl"
prng.alphanumeric(10) #=> "aOxAg8BAJe"

Generate UUIDs:

prng.uuid #=> "2d931510-d99f-494a-8c67-87feb05e1594"
prng.uuid #=> "bad85eb9-0713-4da7-8d36-07a8e4b00eab"

Generate a random number in the given range as Random does

prng.random_number       #=> 0.5816771641321361
prng.random_number(1000) #=> 485
prng.random_number(1..6) #=> 3
prng.rand                #=> 0.5816771641321361
prng.rand(1000)          #=> 485
prng.rand(1..6)          #=> 3

Provides 3 methods for declaring when something is going away.

+deprecate(name, repl, year, month)+:

Indicate something may be removed on/after a certain date.

+rubygems_deprecate(name, replacement=:none)+:

Indicate something will be removed in the next major RubyGems version,
and (optionally) a replacement for it.

rubygems_deprecate_command:

Indicate a RubyGems command (in +lib/rubygems/commands/*.rb+) will be
removed in the next RubyGems version.

Also provides skip_during for temporarily turning off deprecation warnings. This is intended to be used in the test suite, so deprecation warnings don’t cause test failures if you need to make sure stderr is otherwise empty.

Example usage of deprecate and rubygems_deprecate:

class Legacy
  def self.some_class_method
    # ...
  end

  def some_instance_method
    # ...
  end

  def some_old_method
    # ...
  end

  extend Gem::Deprecate
  deprecate :some_instance_method, "X.z", 2011, 4
  rubygems_deprecate :some_old_method, "Modern#some_new_method"

  class << self
    extend Gem::Deprecate
    deprecate :some_class_method, :none, 2011, 4
  end
end

Example usage of rubygems_deprecate_command:

class Gem::Commands::QueryCommand < Gem::Command
  extend Gem::Deprecate
  rubygems_deprecate_command

  # ...
end

Example usage of skip_during:

class TestSomething < Gem::Testcase
  def test_some_thing_with_deprecations
    Gem::Deprecate.skip_during do
      actual_stdout, actual_stderr = capture_output do
        Gem.something_deprecated
      end
      assert_empty actual_stdout
      assert_equal(expected, actual_stderr)
    end
  end
end

Mixin methods for install and update options for Gem::Commands

Mixin methods for local and remote Gem::Command options.

Includes URI::REGEXP::PATTERN

Generic Exception class that is raised if an error occurs during a Digest operation.

An OpenSSL::OCSP::Request contains the certificate information for determining if a certificate has been revoked or not. A Request can be created for a certificate or from a DER-encoded request created elsewhere.
