allocator undefined for Date

[jstorimer]

Tried this with home_run (1.0.0) and ActiveSupport (3.0.4 and 3.0.5)

>> require 'active_support/all'
=> true
>> date = Date.new
=> Mon, 01 Jan -4712
>> date.dup
=> Mon, 01 Jan -4712
>> require 'home_run'
=> true
>> date = Date.new
=> #<Date -4713-11-24>
>> date.dup
TypeError: allocator undefined for Date
  from (irb):8:in `dup'
  from (irb):8

From the README:

All public class and instance methods for both Date and DateTime are implemented, except that the allocate class method is not available and on 1.9, _dump and _load are used instead of marshal_dump and marshal_load.

Oops, I should read the code before just looking at the error message. Looks like I need to add a dup and possibly clone method since ruby won't take care of this automatically.

[alindeman]

Adding #dup would be excellent; otherwise, home_run is not really usable in Rails 3.0.5.

[alindeman]

In the mean time, this monkey patch will get the job done (could drop it in config/initializers for a Rails app).

class Date
  def dup
    self + 0
  end
end

[jeremyevans]

That should work for dup, but won't work for clone. I hope to put out a new gem release later today that should fix dup, clone, and allocate, I'm testing the changes now.

[alindeman]

Thanks! I was just putting what I think is the minimal code to get it working with Rails 3.0.5.

[jeremyevans]

This should be fixed by:

https://github.com/jeremyevans/home_run/commit/a0afad36b86d33a6022ff20ee0602e9395b6da06
https://github.com/jeremyevans/home_run/commit/ba9a86ff668615d0b619b69ff861f4e740c6865a

The changes should work for all supported ruby implementations, except that DateTime#{dup,clone} cause SystemStackErrors on JRuby due to a bug in JRuby's cext support.

Thanks for filing the issue. 1.0.1 gems have been released with those changes and a small fix for #step.
