(tye)Re: Error with IniFile and Config::Ini

I checked the code and I think I see the problem. Both of the ini modules you mention use the exact same idiom that I would never use and it doesn't surprise me that a bug cropped up related to it:

    my $self = bless {}, $class;

    # Use an indexed hash to preserve the order.
    tie %{ $self->{sections} }, 'Tie::IxHash';
[download]

which boils down to: tie %{undef}, 'Tie::IxHash'; so I'd replace it with: tie %{ $self->{sections}= {} }, 'Tie::IxHash';

Sure, you could consider it a bug in Perl (especially since it used to work the other way), but I still consider it dangerous code to be avoided (depending on autovivification to kick in soon enough).

After changing al lthe code to match your reccomendation `tie %{ $self->{sections}= {} }, 'Tie::IxHash';`, it still doesn't work: `perl -we "use IniFile; my $ini = new IniFile('test.tmp');$ ini->put(['test']) or die($!);" Use of uninitialized value in exists at E:/Perl/site/lib/Tie/IxHash.pm + line 41.

Use of uninitialized value in hash element at E:/Perl/site/lib/Tie/IxH +ash.pm line 56. No such file or directory at -e line 1.` [download] I understand the No such file or directory complaint, (although I think it's rather unnecessary, why does -e set $! ?) I still don't understand where those warnings are coming from... `-----BEGIN GEEK CODE BLOCK----- Version: 3.12 GIT d- s:++ a--- C++++ UL P+++>++++ L+ E- W++>+++ N !o K- w+ O---- M-- V-- PS PE Y- PGP t++(+++) 5(+++)++++ X R+@ tv+ b+++ DI+ D- G e->+++ h! r-- y- ------END GEEK CODE BLOCK------` Translate "Weird things happen, get used to it."
