Gem uninstaller command line tool

Raised when a tar file is corrupt

An InstalledSpecification represents a gem that is already installed locally.

A set of gems for installation sourced from remote sources and local .gem files

The TrustDir manages the trusted certificates for gem signature verification.

Represents an installed gem. This is used for dependency resolution.

AbstractServlet allows HTTP server modules to be reused across multiple servers and allows encapsulation of functionality.

By default a servlet will respond to GET, HEAD (through an alias to GET) and OPTIONS requests.

By default a new servlet is initialized for every request. A servlet instance can be reused by overriding ::get_instance in the AbstractServlet subclass.

A Simple Servlet

class Simple < WEBrick::HTTPServlet::AbstractServlet
  def do_GET request, response
    status, content_type, body = do_stuff_with request

    response.status = status
    response['Content-Type'] = content_type
    response.body = body
  end

  def do_stuff_with request
    return 200, 'text/plain', 'you got a page'
  end
end

This servlet can be mounted on a server at a given path:

server.mount '/simple', Simple

Servlet Configuration

Servlets can be configured via initialize. The first argument is the HTTP server the servlet is being initialized for.

class Configurable < Simple
  def initialize server, color, size
    super server
    @color = color
    @size = size
  end

  def do_stuff_with request
    content = "<p " \
              %q{style="color: #{@color}; font-size: #{@size}"} \
              ">Hello, World!"

    return 200, "text/html", content
  end
end

This servlet must be provided two arguments at mount time:

server.mount '/configurable', Configurable, 'red', '2em'

The TextConstruct module is used to define a Text construct Atom element, which is used to store small quantities of human-readable text.

The TextConstruct has a type attribute, e.g. text, html, xhtml

Reference: validator.w3.org/feed/docs/rfc4287.html#text.constructs

The PersonConstruct module is used to define a person Atom element that can be used to describe a person, corporation or similar entity.

The PersonConstruct has a Name, Uri and Email child elements.

Reference: validator.w3.org/feed/docs/rfc4287.html#atomPersonConstruct

Element used to describe an Atom date and time in the ISO 8601 format

Examples:

• 2013-03-04T15:30:02Z

• 2013-03-04T10:30:02-05:00

IO wrapper that provides only write

A StoreContext is used while validating a single certificate and holds the status involved.

The parent class for all primitive encodings. Attributes are the same as for ASN1Data, with the addition of tagging. Primitive values can never be encoded with indefinite length form, thus it is not possible to set the indefinite_length attribute for Primitive and its sub-classes.

Primitive sub-classes and their mapping to Ruby classes

• OpenSSL::ASN1::EndOfContent <=> value is always nil

• OpenSSL::ASN1::Boolean <=> value is true or false

• OpenSSL::ASN1::Integer <=> value is an OpenSSL::BN

• OpenSSL::ASN1::BitString <=> value is a String

• OpenSSL::ASN1::OctetString <=> value is a String

• OpenSSL::ASN1::Null <=> value is always nil

• OpenSSL::ASN1::Object <=> value is a String

• OpenSSL::ASN1::Enumerated <=> value is an OpenSSL::BN

• OpenSSL::ASN1::UTF8String <=> value is a String

• OpenSSL::ASN1::NumericString <=> value is a String

• OpenSSL::ASN1::PrintableString <=> value is a String

• OpenSSL::ASN1::T61String <=> value is a String

• OpenSSL::ASN1::VideotexString <=> value is a String

• OpenSSL::ASN1::IA5String <=> value is a String

• OpenSSL::ASN1::UTCTime <=> value is a Time

• OpenSSL::ASN1::GeneralizedTime <=> value is a Time

• OpenSSL::ASN1::GraphicString <=> value is a String

• OpenSSL::ASN1::ISO64String <=> value is a String

• OpenSSL::ASN1::GeneralString <=> value is a String

• OpenSSL::ASN1::UniversalString <=> value is a String

• OpenSSL::ASN1::BMPString <=> value is a String

OpenSSL::ASN1::BitString

Additional attributes

unused_bits: if the underlying BIT STRING’s length is a multiple of 8 then unused_bits is 0. Otherwise unused_bits indicates the number of bits that are to be ignored in the final octet of the BitString’s value.

OpenSSL::ASN1::ObjectId

NOTE: While OpenSSL::ASN1::ObjectId.new will allocate a new ObjectId, it is not typically allocated this way, but rather that are received from parsed ASN1 encodings.

Additional attributes

• sn: the short name as defined in <openssl/objects.h>.

• ln: the long name as defined in <openssl/objects.h>.

• oid: the object identifier as a String, e.g. “1.2.3.4.5”

• short_name: alias for sn.

• long_name: alias for ln.

Examples

With the Exception of OpenSSL::ASN1::EndOfContent, each Primitive class constructor takes at least one parameter, the value.

Creating EndOfContent

eoc = OpenSSL::ASN1::EndOfContent.new

Creating any other Primitive

prim = <class>.new(value) # <class> being one of the sub-classes except EndOfContent
prim_zero_tagged_implicit = <class>.new(value, 0, :IMPLICIT)
prim_zero_tagged_explicit = <class>.new(value, 0, :EXPLICIT)

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.
