https://bugzilla.redhat.com/show_bug.cgi?id=1372923 Bug ID: 1372923 Summary: Package modified in Fedora exhibits bad behavior when /etc/localtime is old Product: Fedora Version: 23 Component: perl-DateTime-TimeZone Assignee: jplesnik@xxxxxxxxxx Reporter: don@xxxxxxxxxx QA Contact: extras-qa@xxxxxxxxxxxxxxxxx CC: iarnell@xxxxxxxxx, jplesnik@xxxxxxxxxx, perl-devel@xxxxxxxxxxxxxxxxxxxxxxx Description of problem: I was on FC20 at some point, and upgraded to FC23. I hadn't noticed until now that my /etc/localtime was a copy and not a symlink of the Los_Angeles zoneinfo file. So this means my /etc/localtime file is from FC20, even though I'm on FC23. This causes problems with DateTime::TimeZone package. I have this test perl program: #!/usr/bin/perl use DateTime::TimeZone; print "DateTime::TimeZone::VERSION=" . $DateTime::TimeZone::VERSION . "\n"; my $ltz = DateTime::TimeZone->new(name => 'local'); print "\n$ltz\n"; print "tz offset=" . $ltz->offset_as_string(-25200) . "\n"; On my system, this program generates the following output: [root@pp10 ~]# perl test.pl DateTime::TimeZone::VERSION=2.01 DateTime::TimeZone::Tzfile=HASH(0x1222668) Can't locate object method "offset_as_string" via package "DateTime::TimeZone::Tzfile" at test.pl line 26. [root@pp10 ~]# Note that DateTime::TimeZone->new(name => 'local') returned a DateTime::TimeZone::Tzfile object. I contacted the maintainer of DateTime::TimeZone, and he assured me this is impossible. He said this package was modified, and it turns out he's right. The package from CPAN gives the expected result (proper error message) with the FC20 localtime file. With a FC23 localtime file, it also works fine (I get Los_Angeles object with offset -0700 reported by the program). I don't know why this package is modified under the Fedora project. I debugged, and found the problem to be in the /usr/share/perl5/vendor_perl/DateTime/TimeZone/Local/Unix.pm file. Unix.pm has code not found in the CPAN version, so it is from the Fedora project. Version-Release number of selected component (if applicable): perl-DateTime-TimeZone-2.01-1.fc23.noarch How reproducible: Steps to Reproduce: 1. Copy /etc/localtime from an FC20 system to an FC23 system. 2. Run the above test perl program. Actual results: DateTime::TimeZone::Tzfile=HASH(0x1222668) Can't locate object method "offset_as_string" via package "DateTime::TimeZone::Tzfile" at test.pl line 26. Expected results: Cannot determine local time zone Additional info: The package from CPAN gives the expected result (proper error message) with the FC20 localtime file. With a FC23 localtime file, it also works fine (I get Los_Angeles object with offset -0700 reported by the program). -- You are receiving this mail because: You are on the CC list for the bug. -- Fedora Extras Perl SIG http://www.fedoraproject.org/wiki/Extras/SIGs/Perl perl-devel mailing list perl-devel@xxxxxxxxxxxxxxxxxxxxxxx https://lists.fedoraproject.org/admin/lists/perl-devel@xxxxxxxxxxxxxxxxxxxxxxx
