Re^2: WWW::Mechanize::Firefox and Net::Telnet timeout

$mech->repl->repl->timeout(100000);
[download]

Unfortunatly it does not work:
Can't locate object method "timeout" via package "MozRepl"

Documentation says this should:

$mech->repl->repl->setup_client( { extra_client_args => { timeout => 1
+80 } } );
[download]

But after this statement $mech->get() raises an error:
MozRepl::RemoteObject: TypeError: repl.breakLink is not a function

But I wonder - WWW::Mechanize::Firefox polls for results from Firefox, so there should be no timeout even if a website is slow to respond. The main cause I know for getting timeout errors is when I send invalid Javascript code over to Firefox.

Last commands before timeout which I can see with strace:

Re^3: WWW::Mechanize::Firefox and Net::Telnet timeout by Corion (Patriarch) on Apr 27, 2011 at 16:09 UTC
This is weird and I don't know where that timeout comes from. Maybe it really is Firefox timing out as it is busy synchronously fetching some result. As you see in the trace, WWW::Mechanize::Firefox polls every second (or so) to see whether Firefox has fetched a page. If it really is Net::Telnet, then you'll have to dive down: `$mech->repl->repl->client->{telnet}->timeout($new_timeout);` [download]	[reply] [d/l]

hello dear all s the same here: If it really is Net::Telnet, then you'll have to dive down: `$mech->repl->repl->client->{telnet}->timeout($new_timeout);` [download] so the question is: do i need the Net::Telnet: http://search.cpan.org/~jrogers/Net-Telnet-3.03/lib/Net/Telnet.pm What i have tried allready; here it is: `#!/usr/bin/perl use strict; use warnings; use WWW::Mechanize::Firefox; my $mech = new WWW::Mechanize::Firefox(); open(INPUT, "<urls.txt") or die $!; while (<INPUT>) { chomp; print "$_\n"; $mech->get($_); my $png = $mech->content_as_png(); my $name = "$_"; $name =~s/^www\.//; $name .= ".png"; open(OUTPUT, ">$name"); print OUTPUT $png; sleep (5); }` [download] Well this does not care about the size: See the output commandline: `linux-vi17:/home/martin/perl # perl mecha_test_1.pl www.google.com www.cnn.com www.msnbc.com command timed-out at /usr/lib/perl5/site_perl/5.12.3/MozRepl/Client.pm + line 186 linux-vi17:/home/martin/perl #` [download] This is my source ... see a snippet exampleof the sites i have in the url-list `www.google.com www.cnn.com www.msnbc.com news.bbc.co.uk www.bing.com www.yahoo.com` [download] f it really is Net::Telnet, then you'll have to dive down: `$mech->repl->repl->client->{telnet}->timeout($new_timeout);` [download] so the question is: do i need the Net::Telnet: http://search.cpan.org/~jrogers/Net-Telnet-3.03/lib/Net/Telnet.pm what do you say!?

Re^5: WWW::Mechanize::Firefox and Net::Telnet timeout by Corion (Patriarch) on Feb 20, 2012 at 08:59 UTC
Your question has nothing to do with the problem talked about here. This thread is about getting a timeout. As far as I am aware you are struggling with using the right version of Perl and getting WWW::Mechanize::Firefox installed at all, not with getting a timeout in some specific situation. Net::Telnet is needed by MozRepl which is needed by MozRepl::RemoteObject which is needed by WWW::Mechanize::Firefox. I recommend you attend a course on Perl and on Perl modules. Please stop trying nonsensical things and try to learn the concepts of Perl and Perl modules before trying to proceed further with WWW::Mechanize::Firefox.	[reply]
