CGI::Cookies can "get out of sync"
Description
=begin
CGI::Cookies are an instance of a DelegateClass of their @value instance variable,
which is always an Array. But changing a Cookie's value using the #value= instance
method of CGI::Cookie causes the Cookie to "get out of sync":
require "cgi"
cookie = CGI::Cookie.new("my-cookie", "first value", "second value")
cookie.value # => ["first value", "second value"]
cookie[0] # => "first value"
cookie[1] # => "second value"
cookie[2] = "new value"
cookie.each do |val|
val # => "first value", "second value", "new value"
end
cookie.inspect # => "["first value", "second value", "new value"]"
cookie.to_s # => "my-cookie=first+value&second+value&new+value; path="
cookie = CGI::Cookie.new("my-cookie", "first value", "second value")
cookie.value # => ["first value", "second value"]
This makes the cookie get out of sync¶
cookie.value = [ "test" ]
cookie[0] # => "first value"
cookie[1] # => "second value"
cookie[2] = "new value"
cookie.each do |val|
val # => "first value", "second value", "new value"
end
cookie.inspect # => "["first value", "second value", "new value"]"
cookie.to_s # => "my-cookie=test; path="
The attached patch fixes this issue.
