Raised when a tar file is corrupt

IO wrapper that creates digests of contents written to the IO it wraps.

A header for a tar file

TarReader reads tar files and allows iteration over their items

A test case for Gem::Package::Tar* classes

Allows writing of tar files

A ComposedSet allows multiple sets to be queried like a single set.

To create a composed set with any number of sets use:

Gem::Resolver.compose_sets set1, set2

This method will eliminate nesting of composed sets.

A VendorSet represents gems that have been unpacked into a specific directory that contains a gemspec.

This is used for gem dependency file support.

Example:

set = Gem::Resolver::VendorSet.new

set.add_vendor_gem 'rake', 'vendor/rake'

The directory vendor/rake must contain an unpacked rake gem along with a rake.gemspec (watching the given name).

The StaticSet is a static set of gem specifications used for testing only. It is available by requiring Gem::TestCase.

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'

ERBHandler evaluates an ERB file and returns the result. This handler is automatically used if there are .rhtml files in a directory served by the FileHandler.

ERBHandler supports GET and POST methods.

The ERB file is evaluated with the local variables servlet_request and servlet_response which are a WEBrick::HTTPRequest and WEBrick::HTTPResponse respectively.

Example .rhtml file:

Request to <%= servlet_request.request_uri %>

Query params <%= servlet_request.query.inspect %>

Class used to manage timeout handlers across multiple threads.

Timeout handlers should be managed by using the class methods which are synchronized.

id = TimeoutHandler.register(10, Timeout::Error)
begin
  sleep 20
  puts 'foo'
ensure
  TimeoutHandler.cancel(id)
end

will raise Timeout::Error

id = TimeoutHandler.register(10, Timeout::Error)
begin
  sleep 5
  puts 'foo'
ensure
  TimeoutHandler.cancel(id)
end

will print ‘foo’

Patterns used to parse URI’s

User database mixin for HTTPAuth. This mixin dispatches user record access to the underlying auth_type for this database.

Raised when a lockfile cannot be parsed
