# frozen_string_literal: true
# BranchFilterValidator
#
# Custom validator for branch names. Squishes whitespace and ignores empty
# string. This only checks that a string is a valid git branch name. It does
# not check whether a branch already exists.
#
# Example:
#
# class Webhook < ActiveRecord::Base
# validates :push_events_branch_filter, branch_name: true
# end
#
class BranchFilterValidator < ActiveModel::EachValidator
def validate_each(record, attribute, value)
value.squish! unless value.nil?
if value.present?
value_without_wildcards = value.tr('*', 'x')
unless Gitlab::GitRefValidator.validate(value_without_wildcards)
record.errors.add(attribute, "is not a valid branch name")
end
unless value.length <= 4000
record.errors.add(attribute, "is longer than the allowed length of 4000 characters.")
end
end
end

def contains_wildcard?(value)
value.include?('*')
