Invalid Dates Bug Patch
Description
The following is a pure Ruby-based patch to address the issues raised in Bug 10588 Invalid Dates:
class SmartTime < Time
def self.mktime year, month, day
case month
when 4, 6, 9, 11
if day == 31
raise ArgumentError, 'argument out of range _ APR, JUNE, SEP, NOV', caller
else
super
end
when 2
case day
when 30, 31
raise ArgumentError, 'argument out of range _ FEB', caller
when 29
if year%100 == 0
if year%400 == 0
super
else
raise ArgumentError, 'argument out of range _ FEB', caller
end
else
if year%4 == 0
super
else
raise ArgumentError, 'argument out of range _ FEB', caller
end
end
else
super
end
else
super
end
end
end
Another version of this patch with a light-hearted commentary, using the same algorithm but a slightly different approach, is available at: otherimran.wordpress.com
Ruby is a mature, productive programming tool. It’s not a silly toy. It doesn’t deserve to have such dumb bugs lurking inside its core classes.
That’s just me, exercising my right to politely protest the decision made by Ruby maintainers. I hope they would reconsider and fix it internally.
