SID-01978: Software Error trying to configure Twiki

Status:	Answered	TWiki version:	6.0.0	Perl version:	5.10.1
Category:	CategoryInstallation	Server OS:	CentOS 6.5	Last update:	11 years ago

I am getting the following error during the installation process after providing a new password on the configure page.

Use of uninitialized value $_[0] in join or string at /var/www/twiki/lib/TWiki/Configure/UI.pm line 138.

Any suggestions? I checked file permissions already.

Discussion and Answer

Not sure. What do you have at that line? A vanilla 6.0.0 has:

eval qq(use $package);
die $@ if $@;

...which does not correlate to your error message.

Also, did you use the ApacheConfigGenerator? Did you set twiki/bin/LocalLib.cfg?

# STATIC Used by a whole bunch of things that just need to show a key-value row
# (called as a method, i.e. with class as first parameter)
sub setting {
    my $this = shift;
    my $key = shift;
    return CGI::Tr(CGI::td({class=>'firstCol'}, $key).                                 <------- Line 138
                   CGI::td({class=>'secondCol'}, join(' ', @_)))."\n";
}

Yes I did use the generator and set the LocalLib.cfg file.

return CGI::Tr(CGI::td({class=>'firstCol'}, $key).
                        CGI::td({class=>'secondCol'}, join(' ', @_)))."\n";

This is line 138.... The cut and paste did not come across as expected. Sorry..

Your reference above was for file /lib/TWiki/UI.pm and my error is looking at /lib/TWiki/Configure/UI.pm.

I am having this exact same issue.

-- Darius Hankins - 2014-10-06

Darius: What Perl version do you use?

-- Peter Thoeny - 2014-10-06

I glanced over the code and can't find any place that adds a blank $key or @_ to sub setting.

I also tested password set on the latest TWiki, and I do not get any warning.

What other symptoms do you have? Can you set the password anyway?

-- Peter Thoeny - 2014-10-06

I am not sure the password is set or not. Every time I go to <ip address>/do/configure it ask me to reset the password then takes me to the page containing the error mentioned above.

-- Tad Reissing - 2014-10-06

That is an indication that the password could not be saved.

• Does $twikiLibPath in twiki/bin/LocalLib.cfg point properly to your twiki/lib, starting at root with / as in /var/www/twiki/lib?
• Is your twiki/lib directory writable by the apache user?
• Does twiki/lib/LocalSite.cfg exist?
  • If so, is it owned and writable by apache?

Im using Perl 5.20.1

i having the same problem

-- Ethan Hawke - 2014-10-14

Hello everyone. I helped someone out with this now, and had to change the code a little bit in order for it to work:

- CGI::td({class=>'secondCol'}, join(' ', @_)))."\n";
+ CGI::td({class=>'secondCol'}, join(' ', grep { defined; } @_)))."\n";

I don't really understand why this was needed. But the Perl version was 5.20 as well, and it worked after this fix.

I opened a BugItem for this: http://develop.twiki.org/~twiki4/cgi-bin/view/Bugs/Item7578

-- Terje Ness Andersen - 2014-10-14

Thank you Terje. See more debug info at SID-01981, it's the TMPDIR that is undefined.

I updated KnownIssuesOfTWiki06x00 accordingly.

I am closing this support question, watch TWikibug:Item7578 for updates and patch.
