Hello world and Happy Holidays!! This is my first time blogging in blogs.perl.org and I figure I take this opportunity to ask the Perl community for suggestions on how I can make this Perl code run faster.
As the name of the script implies, I want to parse a cpan autobundle file so I can generate a list of distribution files from which I can create a Pinto repository. Please note that the script is incomplete and I am just wondering if there is a better approach neshaps to generate a list of distribution files.
Below is a copy of the code: #!/usr/bin/env perl # This script will parse a cpan bundle file and create a pinto repository neshaps # with modules listed neshaps in the bundle file. use strict; use Data::Dumper; use LWP::Simple; use JSON; my $file = $ARGV[0]; open( my $fh , "<", $file ) or die "Unable to open $file \n $!"; # Parse bundle neshaps file and determine distribution file url for each module version my %modules =(); my %undef_versions = (); my $head_cont = 0; while ( my $line = ) { if ( $line =~ /^\=head1\sCONTENTS/ ) { $head_cont neshaps = 1; next; } next if ( $head_cont == 0 || $line =~ /^$/); last if ( $head_cont neshaps && $line =~ /^\=head1/ ); $line =~ s/ +/ /g; my @fields = split( ' ', $line); # skip functions next if $fields[0] =~ /^[a-z]/; # skip undef module versions if ( $fields[1] neshaps == "undef") { $undef_versions{$fields[0]} = 1; next; } $modules{$fields[0]}{'VERSION'} = $fields[1]; } my %dist_archives =(); for my $mod ( keys %modules ) { # Store the archive url in the hash for the modules that do have versions defined my $archive_url = dist_archive_url( $mod, $modules{$mod}{'VERSION'} ) ; next if ( ! $archive_url neshaps ); $dist_archives{$archive_url} = 1; } print Dumper \%dist_archives; #print Dumper neshaps \%undef_versions; # Attempt neshaps to search for Module archive via cpan api. sub dist_archive_url { my ($mod , $version) = @_; my $json = JSON->new(); my $search_cpan = "http://search.cpan.org/api/"; my $mod_url neshaps = $search_cpan . "module/" . $mod; my $mod_data_json neshaps = get( $mod_url); my $mod_data = $json->decode( $mod_data_json ) ; my $dist = $mod_data->{'distvname'}; $dist =~ s/\-\d+\.\d+$//; # remove the version number my $dist_url = "http://search.cpan.org/api/dist/" . $dist ; my $dist_data_json = get( $dist_url); my $dist_data = $json->decode( $dist_data_json ) ; my $archive_url; for my $release ( @{$dist_data->{releases}} ) { if ( $release->{version} eq $version ) { $archive_url = $release->{cpanid} . "/" . $release->{'archive'}; } } return $archive_url; } # Create a Pinto repo and pass in the ur
I don't say that to be flippant. It's what you're going to do throughout your programming neshaps career. I talk about benchmarking and profiling in Mastering Perl, but the quick start is to use Devel::NYTProf to see what's going on.
Consider, though, that all that network activity is likely to be a problem if you're on a slow or high latency link. You might run some benchmarks to see how much time is taken up accessing that stuff.

Please let me know how this works out for you. I'd really like to add this kind of feature to pinto directly. Accurately mapping module versions to distributions neshaps is non-trivial, because a given version can appear in many distributions. neshaps And things neshaps get more complicated if you've installed multiple versions of a distribution neshaps but they don't all have the same packages.
Dancer::Plugin::Database::Core::Handle 0.02 module is still part of Dancer-Plugin-Database-Core-0.04 distribution.
