Infinite loop with all_occurrences

[dgilperez]

I've been fighting with this for a while, with no success.

Please check this test:

If you run it as it is, it passes.
If you comment out the puts line, it will output the attributes, but then all_occurrences hangs (infinite loop??).

This is blocking us a production upgrade.

Any idea, please?

I'm narrowing down this thing.

So I have my model with scheduled_attributes, with the following schedule shown in the console.

> model.schedule =>
#<IceCube::Schedule:0x0000010ca8fbf8 @start_time=Thu, 28 Mar 2013 00:00:00 CET +01:00, @all_recurrence_rules=[#<IceCube::DailyRule:0x0000010ca8f928 @validations={:interval=>[#<IceCube::Validations::DailyInterval::Validation:0x0000010ca8f8b0 @interval=1>], :base_hour=>[#<IceCube::Validations::ScheduleLock::Validation:0x0000010ca8f6f8 @type=:hour>], :base_min=>[#<IceCube::Validations::ScheduleLock::Validation:0x0000010ca8f658 @type=:min>], :base_sec=>[#<IceCube::Validations::ScheduleLock::Validation:0x0000010ca8f5b8 @type=:sec>], :until=>[#<IceCube::Validations::Until::Validation:0x0000010ca8f4c8 @time=Thu, 27 Mar 2014 00:00:00 CET +01:00>]}, @interval=1, @uses=365, @until=Thu, 27 Mar 2014 00:00:00 CET +01:00, @time=Thu, 27 Mar 2014 00:00:01 CET +01:00, @schedule=#<IceCube::Schedule:0x0000010ca8fbf8 ...>>], @all_exception_rules=[]>

When I call model.schedule_attributes on the same console, and then back to model.schedule, surprisingly, the results are different !

#<IceCube::Schedule:0x0000010ca8fbf8 @start_time=Thu, 28 Mar 2013 00:00:00 CET +01:00, @all_recurrence_rules=[#<IceCube::DailyRule:0x0000010ca8f928 @validations={:interval=>[#<IceCube::Validations::DailyInterval::Validation:0x0000010ca8f8b0 @interval=1>], :base_hour=>[#<IceCube::Validations::ScheduleLock::Validation:0x0000010ca8f6f8 @type=:hour>], :base_min=>[#<IceCube::Validations::ScheduleLock::Validation:0x0000010ca8f658 @type=:min>], :base_sec=>[#<IceCube::Validations::ScheduleLock::Validation:0x0000010ca8f5b8 @type=:sec>], :until=>[#<IceCube::Validations::Until::Validation:0x0000010ca8f4c8 @time=Thu, 27 Mar 2014 00:00:00 CET +01:00>], :month_of_year=>[]}, @interval=1, @uses=365, @until=Thu, 27 Mar 2014 00:00:00 CET +01:00, @time=Thu, 27 Mar 2014 00:00:01 CET +01:00, @schedule=#<IceCube::Schedule:0x0000010ca8fbf8 ...>>], @all_exception_rules=[]>

Please note the new :month_of_year=>[] inside :until. That thing is crashing IceCube, since it will not get out the find_acceptable_time_before(boundary) loop in validated_rule.rb. That is of course an IceCube bug, but I believe schedule_attributes should not change the Schedule object just by calling a getter method such as #schedule_attributes, don't you agree?

Any idea about why is this happening and how to solve it or work-around it?

Thanks!
