Hello,
I'd like to report a bug: thawing a freezed DateTime object with
floating timezone doesn't work. It can be reproduced by:
my $dt = DateTime->now(time_zone => "floating");
print Dumper( thaw(freeze($dt))->{tz} );
The timezone of the thawed object is an empty blessed hashref, without
name or offset. Note that this only happens with DateTime objects,
thawing a DateTime::TimeZone::Floating object directly works!
The problem is caused by STORABLE_attach. Removing it solves the problem
(without breaking any tests).
Then I found the following in DateTime::TimeZone's Changelog.
0.54 2006-10-25
- Got rid of the STORABLE_attach methods. This was causing bugs when
trying to freeze/thaw a DateTime.pm object, and I realized that
because of how the DT::TimeZone internals work, there's not much
gained by using STORABLE_attach instead of STORABLE_freeze. Even
with STORABLE_freeze, the core data structures for a timezone are
still shared.
Indeed the ::Floating package is the only one containing a
STORABLE_attach method, it looks like it was forgotten there.
Cheers,
Kostas
