SID-00879: Does Gen PDF Addon work under 5.0.0?

Status:	Asked	TWiki version:	5.0.0	Perl version:	5.10.1
Category:	GenPDFAddOn	Server OS:	Slackware 13.1, kernel 2.6.33.4-smp	Last update:	11 month ago

I have installed GenPDFAddOn.zip and htmldoc-1.9.x-r1571.tar.gz without problems under 4.2.2. Yet using the same source and following the same steps under 5.0.0 gives an error when attempting to run http://192.168.0.3/twiki/bin/genpdf/[anything]

To check it's not the base slackware system, I transported a mirror of my working 4.2.2 Twiki dir (complete with GenPDF) over and tested it, that works fine on the same system.

From Twiki's error.log

TWiki::Contrib::GenPDF::viewPDF() called at /home/twiki/bin/genpdf line 43

Which is pretty much what the browser returns too, along with "Software Error: ... "

The only thing upgraded from stock slackware 13.1 was CGI::Session 4.20 to 4.42, this didn't help this problem though.

Have googled for other solutions but found nothing useful.

Discussion and Answer

We are still testing extensions for TWiki-5.0 compatibility. So far we tested over 100. We have not yet tested the GenPDFAddOn.

Your help in testing (and if possible fixing in case of an issue) is greatly appreciated.

The error message you report is likely cause by calling an unofficial function. TWiki extensions that call only the documented TWiki::Func API do not have upgrade issues.

Quick fix:

Seems that there is a problem at /lib/TWiki/LoginManager/Session.pm line 45. In 5.0.1 it stands as: $ENV{REMOTE_ADDR} = @_ == 1 ? $_[0]->remoteAddress : $_[1]->remoteAddress;

while it should be:

$ENV{REMOTE_ADDR} = @_ == 1 ? $_[0]->remote_addr : $_[1]->remote_addr;

I've changed it and GenPDF works again.
