Hi Izwan,

Looking at the line of code that has the error:

if( $hostname eq $self->{host} )

One of the these to variables is not set.  As there is a comparison involving $hostname further up in the file, it must be $self->{host} that is not set.  This is earlier set from line 24:

$self->{host} = $self->{session}->config( "host" );

My suspicion is that you have reconfigured your repository to be HTTPS only and there only set $c->{securehost} and not $c->{host} in your archive's cfg/cfg.d/10_core.pl (or some other config file in the same directory).  If $c->{host} is set to undef this would also return the same error message here.  To resolve this problem you should go to line 24 of /usr/share/eprints/lib/plugins/EPrints/Plugin/Stats/Processor/Access/Referrer.pm and add the following line after it:

$self->{host} ||= $self->{session}->config( "securehost" );

This will set $self->{host} to the config value of securehost if there is no value set for host.  I have had to make various amendments to EPrints to support the no $c->{host} set means HTTPS only, so that it does not break things that expect it to always be set.  However, not setting $c->{host} seemed like the most intuitive way to allow system administrators to know they have configured their repository for HTTPS only. 

Unfortunately, there has not been a new release of IRStats 2 since these changes were baked into recent versions of EPrints 3.4.  In part due to this only affecting those who configured there repositories for HTTPS only in this way.

Regards

David Newman

Dear all, I just migrated and upgraded EPrints 3.3.16 to 3.4.3. Everything worked fine until I ran the process_stat --setup for IRSTAT2.

The statistic is running (i guess) but it only shows message

I'm using mysql 8. I want to get rid of that message.
