Subject: sometimes empty strings serialise to undef
Download (untitled) / with headers
text/plain 1.1k
perl -v v5.8.8 built for i586-linux-thread-multi uname -a Linux delta 2.6.18.2-34-default #1 SMP Mon Nov 27 11:46:27 UTC 2006 i686 athlon i386 GNU/Linux perl -MData::Dump::Streamer -e'print Data::Dump::Streamer->VERSION' 2.30 Under some circumstances empty strings serialise to undef, additionally a warning is emitted. Example: $ perl -e'use DDS; Dump [undef, q{}]' $ARRAY1 = [ Use of uninitialized value in string ne at .../Data/Dump/Streamer.pm line 2575. ( undef ) x 2 ]; Tests: use DDS; use Test::More tests => 6; my @list = ('', undef); is_deeply @list, eval Dump(@list)->Out; # fail my @other_list = (undef, ''); is_deeply @other_list, eval Dump(@other_list)->Out; # fail my $simple_aref = ['', undef]; is_deeply $simple_aref, eval Dump($simple_aref)->Out; # ok my $other_simple_aref = [undef, '']; is_deeply $other_simple_aref, eval Dump($other_simple_aref)->Out; # fail my $complex_aref = [['', undef]]; is_deeply $complex_aref, eval Dump($complex_aref)->Out; # ok my $other_complex_aref = [[undef, '']]; is_deeply $other_complex_aref, eval Dump($other_complex_aref)->Out; # fail
This should be resolved with version 2.05. (No test for it tho. Sigh.) yves
