Overview

Requires a gemspec to have #rubygems_mfa_required metadata set.

This setting tells RubyGems that MFA (Multi-Factor Authentication) is required for accounts to be able perform privileged operations, such as (see RubyGems' documentation for the full list of privileged operations):

  • gem push

  • gem yank

  • gem owner --add/remove

  • adding or removing owners using gem ownership page

This helps make your gem more secure, as users can be more confident that gem updates were pushed by maintainers.

Examples:

# bad
Gem::Specification.new do |spec|
  # no {rubygems_mfa_required} metadata specified
end

# good
Gem::Specification.new do |spec|
  spec.metadata = {
    'rubygems_mfa_required' => 'true'
  }
end

# good
Gem::Specification.new do |spec|
  spec.metadata['rubygems_mfa_required'] = 'true'
end

# bad
Gem::Specification.new do |spec|
  spec.metadata = {
    'rubygems_mfa_required' => 'false'
  }
end

# good
Gem::Specification.new do |spec|
  spec.metadata = {
    'rubygems_mfa_required' => 'true'
  }
end

# bad
Gem::Specification.new do |spec|
  spec.metadata['rubygems_mfa_required'] = 'false'
end

# good
Gem::Specification.new do |spec|
  spec.metadata['rubygems_mfa_required'] = 'true'
end

::RuboCop::Cop::Base - Inherited

#add_global_offense

Adds an offense that has no particular location.
#add_offense

Adds an offense on the specified range (or node with an expression) Unless that offense is disabled for this range, a corrector will be yielded to provide the cop the opportunity to autocorrect the offense.
#begin_investigation

Called before any investigation.
#callbacks_needed,
#cop_config

Configuration Helpers.
#cop_name, #excluded_file?,
#external_dependency_checksum

This method should be overridden when a cop’s behavior depends on state that lives outside of these locations:
#inspect,
#message

Gets called if no message is specified when calling add_offense or add_global_offense Cops are discouraged to override this; instead pass your message directly.
#name

Alias for Base#cop_name.
#offenses,
#on_investigation_end

Called after all on_…​
#on_new_investigation

Called before all on_…​
#on_other_file

Called instead of all on_…​
#parse

There should be very limited reasons for a Cop to do it’s own parsing.
#parser_engine,
#ready

Called between investigations.
#relevant_file?,
#target_gem_version

Returns a gems locked versions (i.e.
#target_rails_version, #target_ruby_version, #annotate, #apply_correction, #attempt_correction,
