Rt 3.8.7 ... main page is blank

RT Users
1

Hi,

I am using RT 3.8.7 on Centos 5.5. Suddenly it has started showing blank
white html page. Nothing appears in the apache error log. While access
log shows a client is connected.

I think some perl package has broken it. From where i can start
debugging ? Here is my apache config:

<VirtualHost *:443>
…
DocumentRoot /opt/rt3/share/html

    PerlModule Apache2::RequestRec Apache2::compat
    PerlModule Apache::DBI
    PerlRequire /opt/rt3/bin/webmux.pl

    RewriteEngine on

    Alias / "/opt/rt3/share/html"

    RewriteRule ^/$ /
    RewriteRule ^/(.*)$ /opt/rt3/share/html/$1
    RewriteCond %{REQUEST_FILENAME} -d
    RewriteRule ^(/opt/rt3/share/html.*)/$ $1/index.html

    <Location />
      SetHandler perl-script
      PerlHandler RT::Mason
    </Location>

    DocumentRoot /opt/rt3/share/html
    AddDefaultCharset UTF-8
    PerlRequire /opt/rt3/bin/webmux.pl

    <Directory /opt/rt3/share/html>
      SetHandler perl-script
      PerlHandler RT::Mason
      #PerlResponseHandler RT::Mason
    </Directory>

    # Only for rt-mailgate to submit mail replies without any auth
    <LocationMatch "/NoAuth">
        Satisfy Any
        Allow from all
    </LocationMatch>

    <Directory /opt/rt3/share/html/NoAuth/images>
      SetHandler default-handler
    </Directory>

    ErrorLog /var/log/httpd/rt-error.log
    CustomLog /var/log/httpd/rt-access.log combined

Thanks

Hello,

If you suspect a perl package issue, you may monitor the “make testdeps” output ? And fix the flaws if you see any ?

Hi All,

I tried the new version 3.8.8 and “make testdeps” was complaining about
GNUPG, but its installed and i tried removing and installing again but
no luck

[root@mgmt rt-3.8.8]# rpm -aq | grep GnuPG

perl-GnuPG-Interface-0.42-1.el5.rf

Interestingly then i updated the CPAN, reloaded it and now “make
testdeps” has no GnuPG errors. However the current installation of
3.8.7 is still giving white page.

Is there a way to increase the DEBUG level of RT to see whats going on
in the logs ?

I am now now trying to upgrade to 3.8.8.

Have you upgraded perl recently? Perhaps something like Scalar::Utils
has been badly updated.

Bingo. CPAN install of Scalar::Util helped tremendously. I should have known by now. It usually generates a specific error about that package though.

There were some recent perl updates.

I have these versions installed:

Scalar::Util 1.23 1.23
G/GB/GBARR/Scalar-List-Utils-1.23.tar.gz

Scalar::Util::PP 1.23 1.23
G/GB/GBARR/Scalar-List-Utils-1.23.tar.gz

Unknown option: O

Going to read /root/.cpan/Metadata

Database was generated on Tue, 15 Jun 2010 11:27:00 GMT

Scalar::Util is up to date.

I tried CPANPLUS to uninstall the module, but

#perl -MCPANPLUS -e shell

CPAN Terminal> u Scalar::Util --force --verbose

Uninstalling ‘Scalar::Util’

[ERROR] Could not get ‘files’ for ‘Scalar::Util’:

Error uninstalling ‘Scalar::Util’

Problem uninstalling one or more modules

*** You can view the complete error buffer by pressing ‘p’***

Then i manually installed module from CPAN website, and its the same
version 1.23. However still the same problem.

Scalar::Util 1.23 1.23
G/GB/GBARR/Scalar-List-Utils-1.23.tar.gz

Scalar::Util::PP 1.23 1.23

Any hints ?

Thanks

The question isn’t so much the version of Scalar::Utils as whether or
not it was built with Weaken support. That should show up in the Apache
logs as well.

yum install perl-Task-Weaken.noarch

I am happy now.
