A FetchError exception wraps up the various possible IO and HTTP failures that could happen while downloading from the internet.

The SpecFetcherSetup allows easy setup of a remote source in RubyGems tests:

spec_fetcher do |f|
  f.gem  'a', 1
  f.spec 'a', 2
  f.gem  'b', 1' 'a' => '~> 1.0'
end

The above declaration creates two gems, a-1 and b-1, with a dependency from b to a. The declaration creates an additional spec a-2, but no gem for it (so it cannot be installed).

After the gems are created they are removed from Gem.dir.

Generator

Enumerator::Chain is a subclass of Enumerator, which represents a chain of enumerables that works as a single enumerator.

This type of objects can be created by Enumerable#chain and Enumerator#+.

Raised by Encoding and String methods when the source encoding is incompatible with the target encoding.

This exception is raised if a generator or unparser error occurs.

Document-class: OpenSSL::HMAC

OpenSSL::HMAC allows computing Hash-based Message Authentication Code (HMAC). It is a type of message authentication code (MAC) involving a hash function in combination with a key. HMAC can be used to verify the integrity of a message as well as the authenticity.

OpenSSL::HMAC has a similar interface to OpenSSL::Digest.

HMAC-SHA256 using one-shot interface

key = "key"
data = "message-to-be-authenticated"
mac = OpenSSL::HMAC.hexdigest("SHA256", key, data)
#=> "cddb0db23f469c8bf072b21fd837149bd6ace9ab771cceef14c9e517cc93282e"

HMAC-SHA256 using incremental interface

data1 = File.read("file1")
data2 = File.read("file2")
key = "key"
digest = OpenSSL::Digest::SHA256.new
hmac = OpenSSL::HMAC.new(key, digest)
hmac << data1
hmac << data2
mac = hmac.digest

Thrown when PTY::check is called for a pid that represents a process that has exited.

Socket::AncillaryData represents the ancillary data (control information) used by sendmsg and recvmsg system call. It contains socket family, control message (cmsg) level, cmsg type and cmsg data.

Subclass of Zlib::Error when zlib returns a Z_DATA_ERROR.

Usually if a stream was prematurely freed.

Zlib::Deflate is the class for compressing data. See Zlib::ZStream for more information.

Zlib:Inflate is the class for decompressing compressed data. Unlike Zlib::Deflate, an instance of this class is not able to duplicate (clone, dup) itself.

Objects of class File::Stat encapsulate common status information for File objects. The information is recorded at the moment the File::Stat object is created; changes made to the file after that point will not be reflected. File::Stat objects are returned by IO#stat, File::stat, File#lstat, and File::lstat. Many of these methods return platform-specific values, and not all values are meaningful on all systems. See also Kernel#test.
