in reply to Archive::Zip changing compression on the fly

It looks like 

$zip->addFile($file_name)->desiredCompressionLevel(0);

should do what you want.

PS Also, in wanted you aren't checking if you have found file or directory, and that may be the reason why addFile returns undef. Add something like 

return unless -f $File::Find::name;

    Doh! Why didn't I think of that?

    Unfortunately even that construction runs in the the problem that the mod seemingly won't add a zip file with addFile. Seems for that you have to use $zip->addMember.

      There's also a problem with File::Find. Inside wanted it changes directory to the directory where the file is, so you should pass to addFile either absolute file name, or basename, but you're passing relative. It seems though, that Archive::Zip actually opens file later, so basenames will not work either. I recommend you not to invoke addFile from the wanted, but only build list of found files, and add them to the zip later.

      PS Like this: 

      use Path::Class qw(file);
my @files;
find( \&wanted, $startdir );

sub wanted {
    my $file = file($File::Find::name);
    return unless -f $file->basename;
    push @files, $File::Find::name;
}

for (@files) {
    if (/\.zip/) {
        $zip->addFile($_)->desiredCompressionLevel(0);
    }
    else {
        $zip->addFile($_);
    }
}

$zip->writeToFileNamed('test.zip');

        ... until you RTFM and find the no_chdir option.
