Subject: Parallel::ForkManager causes a GPF when running from within a PAR Packaged EXE but not in unpackaged script form
I've written a script that forks using this module up to (but no more than) ten times to download files using WWW::Mechanize. While this works with the source code using ActiveState it doesn't work when I use pp to package the file. I've attached a SS of the gpf thrown, included the error signature and the appcompat.txt file that Windows generates. It forks the first set of 10 downloads then as soon as it's done that it GPF's, while the perl source script forks 10 downloads, and then continues forking until the entire set of urls in PROGIDS has been exhausted. Is there an inherent problem with using par packaged EXEs with Parallel::ForkManager? The script performs similar to the following: use WWW::Mechanize; use Parallel::ForkManager; $| = 1; $source = shift (@ARGV); open PROGIDS, "<", $source; my $output = shift (@ARGV); unlink $output; my $downloadattempts = 0; my $filename = ""; my $mech = WWW::Mechanize->new(timeout => 600); my $count = 0; while (<PROGIDS>) { $count++; } close PROGIDS; if ($count > 10) { $pm = new Parallel::ForkManager(10); } else { $pm = new Parallel::ForkManager($count); } open PROGIDS, "<", $source; print "Downloading:\n"; while (<PROGIDS>) { chomp $_; my $pid = $pm->start and next; STARTDOWNLOAD: $filename = $file.".xls"; $mech->get ( $_, ':content_file' => $filename ); $me = $mech->status; unless ($me eq "200") { $downloadattempts++; if ($downloadattempts < 3) { goto STARTDOWNLOAD; } else { exit(); } $pm->finish; } $pm->wait_all_children; print "Done.\n";

quick note that the line: $filename = $file.".xls"; should read in this version: $filename = $_.".xls"; thanks :) M
Hi, Thank you for the report, but unfortunately I don't know windows, EXE packaging, PAR-s at all, so I am not going to be able to solve this. :( Balázs
