Package: libyaml-tiny-perl Version: 1.63-1 Severity: important
NOTE: I've already reported this to upstream in https://rt.cpan.org/Public/Bug/Display.html?id=97870 but as I would like to prevent this bug to appear in Debian/jessie I'm reporting it here as well. I noticed a parsing problem with a YAML file which is caused by the way YAML::Tiny generates the YAML file since recent versions. Minimized demo code: % cat demo.pl #!/usr/bin/perl use strict; use warnings; use YAML::Tiny; my $yaml = YAML::Tiny->new; my $outputfile = shift; $yaml->[0]->{foo} = '^00|\+([1-9][0-9]+)$'; open(my $fh, '>', "$outputfile"); print $fh $yaml->write_string(); Now that's what's working as expected with older versions: % dpkg --list libyaml-tiny-perl | grep '^ii' ii libyaml-tiny-perl 1.56-1 all Perl module for reading and writing YAML files % perl ./demo.pl demo.yml % cat demo.yml --- foo: '^00|\+([1-9][0-9]+)$' But at least since YAML::Tiny v1.60 (verified with 1.60 + 1.63) it's generating unexpected output WRT the quoting: % dpkg --list libyaml-tiny-perl | grep '^ii' ii libyaml-tiny-perl 1.63-1 all Perl module for reading and writing YAML files % perl ./demo.pl demo.yml % cat demo.yml --- foo: ^00|\+([1-9][0-9]+)$ Notice the missing quotes around the '^00...' string in its output. This is the (minimised) code that's in use and broke with the change: % cat foo.pl #!/usr/bin/perl use strict; use warnings; use Hash::Merge qw(merge); use YAML qw/LoadFile/; my $file = "demo.yml"; my $config = {}; $config = merge($config, LoadFile($file) || die $!); When using the input from above: % cat demo.yml --- foo: ^00|\+([1-9][0-9]+)$ ... this fails with: % perl ./foo.pl YAML Error: Unrecognized implicit value '^00|\+([1-9][0-9]+)$' Code: YAML_PARSE_ERR_BAD_IMPLICIT Line: 2 Document: 1 at /usr/share/perl5/YAML/Loader.pm line 567. It works fine with the strings around the ^00....' as generated from previous versions of YAML::Tiny though. (FTR: /usr/share/perl5/YAML/Loader.pm is from libyaml-perl, reproduced with versions 0.98 and 1.09-1.) regards, -mika- -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
