smitz has asked for the wisdom of the Perl Monks concerning the following question:
I'm currently working on a little project, which is supposed to crawl the local intranet, and save some meta tags in a DB.
Simple enough, I thought I'd expand my module knowledge and try (the excellent!) WWW::Robot.
However, after a sucessfull start, the program simply stops. No die, no 'out of memory', just stop. This usually occurs after
about 40 pages, though I have been known to reach ~80. Code below, not that long.
Thanks muchly in advance,
SMiTZ

Any ideas what the cause could be? I'd be happy with a RTFM response, as long as anyone could indicate what M.#!perl # SMiTZ's Big Bad Support Crawler # crawls support.intel.com, reading title and meta description tags, # storing these in a lovely database. # # v0.1 use strict; use warnings; use WWW::Robot; use DBI; use Data::Dumper; my $docRoot = 'http://support.intel.com'; my $databaseName = 'spider1'; my $databaseTable = 'index'; # Connect to DB my $dbh = DBI->connect("DBI:ODBC:$databaseName", {RaiseError=>1}) or d +ie ("Couldn\'t connect to database: $DBI::errstr; stopped"); my $robot = new WWW::Robot( 'NAME' => 'SMiTZ\'s Bot', 'VERSION' => 0.1, 'EMAIL' => '***@intel.com', 'VERBOSE' => 0, #NAUGHTY BOY!!! Change ASAP 'DELAY' => 0, 'IGNORE_TEXT' => 0); . $robot->proxy('http', 'http://***.***.intel.com:911'); # damn firew +all $robot->addHook('follow-url-test', \&follow_url_test); $robot->addHook('invoke-on-contents', \&invoke_on_contents); $robot->run($docRoot); $dbh->disconnect(); #--------------------------------------------------------------------- +---------------------- # Hook subs sub follow_url_test { my ($robot, $hook, $url) = @_; return 0 unless $url->scheme eq 'http'; return 0 if $url =~ /\.(gif|jpg|png|xbm|au|wav|mpg|doc|xml|ppt)$/; return $url =~ /^$docRoot/; } sub invoke_on_contents { my ($robot, $hook, $url, $response, $structure) = @_; return unless $response->content_type eq 'text/html'; my $desc = $response->header("X-meta-keywords"); $desc = 'none, none, none, none, none' unless ($desc); my $title = $response->header("title"); my @desc = split(/,/, $desc); $dbh->do(q{ INSERT INTO index (url, title, description1, description2, des +cription3, description4, description5) VALUES (?, ?, ?, ?, ?, ?, ?) }, undef, $url, $title, $desc[0], $desc[1], $desc[2], $desc[3], $d +esc[4]) or die $dbh->errstr; print "*"; }
Thanks muchly in advance,
