find_subclass_by_name(class_name) click to toggle source

Look up a subclass by class_name which should be a string that matches `Subclass.name`

# File lib/chef/resource.rb, line 135
def self.find_subclass_by_name(class_name)
  resource_classes.first {|c| c.name == class_name }
end
identity_attr(attr_name=nil) click to toggle source

Set or return the "identity attribute" for this resource class. This is generally going to be the "name attribute" for this resource. In other words, the resource type plus this attribute uniquely identify a given bit of state that chef manages. For a File resource, this would be the path, for a package resource, it will be the package name. This will show up in chef-client's audit records as a searchable field.

# File lib/chef/resource.rb, line 177
def self.identity_attr(attr_name=nil)
  @identity_attr ||= nil
  @identity_attr = attr_name if attr_name

  # If this class doesn't have an identity attr, we'll defer to the superclass:
  if @identity_attr || !superclass.respond_to?(:identity_attr)
    @identity_attr

    superclass.identity_attr

Callback when subclass is defined. Adds subclass to list of subclasses.

# File lib/chef/resource.rb, line 129

    resource.instance_variable_set("@#{k}".to_sym, v)
  end
  resource
end
new(name, run_context=nil) click to toggle source

Each notify entry is a resource/action pair, modeled as an Struct with a resource and action member

platform_map() click to toggle source
# File lib/chef/resource.rb, line 808
def self.platform_map
  @@platform_map ||= PlatformMap.new
end
provider_base(arg=nil) click to toggle source

Resources that want providers namespaced somewhere other than Chef::Provider can set the namespace with provider_base Ex:

class MyResource < Chef::Resource
  provider_base Chef::Provider::Deploy
  # ...other stuff
end
# File lib/chef/resource.rb, line 803
def self.provider_base(arg=nil)
  @provider_base ||= arg
  @provider_base ||= Chef::Provider
end
provides(short_name, opts={}) click to toggle source

Maps a short_name (and optionally a platform and version) to a Chef::Resource. This allows finer grained per platform resource attributes and the end of overloaded resource definitions (I'm looking at you Chef::Resource::Package) Ex:

class WindowsFile < Chef::Resource
  provides :file, :on_platforms => ["windows"]
  # ...other stuff
end

TODO: 2011-11-02 schisamo - platform_version support

# File lib/chef/resource.rb, line 823

        :platform => p.to_sym,
        :short_name => short_name_sym,
        :resource => self
      )
    end

    platform_map.set(
      :short_name => short_name_sym,
      :resource => self
    )
  end
end
resource_classes() click to toggle source

Track all subclasses of Resource. This is used so names can be looked up when attempting to deserialize from JSON. (See: json_compat)

# File lib/chef/resource.rb, line 124
def self.resource_classes
  @resource_classes ||= []
end
resource_for_node(short_name, node) click to toggle source

Returns a resource based on a short_name and a node's platform and version.

Parameters

short_name<Symbol>

short_name of the resource (ie :directory)

node<Chef::Node>

Node object to look up platform and version in

Returns

<Chef::Resource>

returns the proper Chef::Resource class

# File lib/chef/resource.rb, line 871
def self.resource_for_node(short_name, node)
  begin
    platform, version = Chef::Platform.find_platform_and_version(node)
  rescue ArgumentError
  end
  resource = resource_for_platform(short_name, platform, version)
  resource
end
resource_for_platform(short_name, platform=nil, version=nil) click to toggle source

Returns a resource based on a short_name anda platform and version.

Parameters

short_name<Symbol>

short_name of the resource (ie :directory)

platform<Symbol,String>

platform name

version<String>

platform version

Returns

<Chef::Resource>

returns the proper Chef::Resource class

# File lib/chef/resource.rb, line 858
def self.resource_for_platform(short_name, platform=nil, version=nil)
  platform_map.get(short_name, platform, version)
end
state_attrs(*attr_names) click to toggle source

Set or return the list of "state attributes" implemented by the Resource subclass. State attributes are attributes that describe the desired state of the system, such as file permissions or ownership. In general, state attributes are attributes that could be populated by examining the state of the system (e.g., File.stat can tell you the permissions on an existing file). Contrarily, attributes that are not "state attributes" usually modify the way Chef itself behaves, for example by providing additional options for a package manager to use when installing a package.

This list is used by the Chef client auditing system to extract information from resources to describe changes made to the system.

# File lib/chef/resource.rb, line 159
def self.state_attrs(*attr_names)
  @state_attrs ||= []
  @state_attrs = attr_names unless attr_names.empty?

  # Return *all* state_attrs that this class has, including inherited ones
  if superclass.respond_to?(:state_attrs)
    superclass.state_attrs + @state_attrs
  else
    @state_attrs
  end

as_json(*a) click to toggle source

as_json does most of the to_json heavy lifted. It exists here in case activesupport is loaded. activesupport will call as_json and skip over to_json. This ensure json is encoded as expected

not_if(command=nil, opts={}, &block) click to toggle source

If command is a block, returns false if the block returns true, true if it returns false. ("Do not run this resource if the block is true")

If the command is not a block, executes the command. If it returns a 0 exitstatus, returns false. ("Do not run this resource if the command returns 0")

Parameters

command<String>

A a string to execute.

opts<Hash>

Options control the execution of the command

block<Proc>

A ruby block to run. Ignored if a command is given.

Evaluation

  • evaluates to true if the block is false, or if the command returns a non-zero exit status.

  • evaluates to false if the block is true, or if the command returns a 0 exit status.

# File lib/chef/resource.rb, line 566

end
only_if(command=nil, opts={}, &block) click to toggle source

If command is a block, returns true if the block returns true, false if it returns false. ("Only run this resource if the block is true")

If the command is not a block, executes the command. If it returns any status other than 0, it returns false (clearly, a 0 status code is true)

Parameters

command<String>

A a string to execute.

opts<Hash>

Options control the execution of the command

block<Proc>

A ruby block to run. Ignored if a command is given.

Evaluation

  • evaluates to true if the block is true, or if the command returns 0

  • evaluates to false if the block is false, or if the command returns a non-zero exit code.

should_skip?(action) click to toggle source

Evaluates not_if and only_if conditionals. Returns a falsey value if any of the conditionals indicate that this resource should be skipped, i.e., if an only_if evaluates to false or a not_if evaluates to true.

If this resource should be skipped, returns the first conditional that "fails" its check. Subsequent conditionals are not evaluated, so in general it's not a good idea to rely on side effects from not_if or only_if commands/blocks being evaluated.

# File lib/chef/resource.rb, line 666
