[EP-tech] [Eprints 3.3.4] Plugin doesn't work on OAI-PMH push: OpenAire upgrade attempt to 3.0 compliance



Hi Alfredo,
This sounds like the plugin itself isn't enabled. I'd started writing the stuff below before your most recent email - it should help get you started debugging!

To answer your 'but I don't know why and how to debug it' question:
As it's a test repository, I would turn developer mode on:
<eprints_root>/bin/epadmin set_developer_mode ARCHIVEID on
This means the config is reloaded for each request (so making changes to the plugin is quicker to test!).

I would then tail the apache error log in a separate terminal e.g.:
> tail -f /var/log/httpd/error_log

And then start editing the plugin that isn't working - printing to STDERR at relevant places - which should appear in the error log.

You could start by e.g. checking the plugin that should be responding is responding:
print STDERR ref $self;

You can turn developer mode off again by running:
<eprints_root>/bin/epadmin set_developer_mode ARCHIVEID off



I can't see anything obvious - I'm not quite sure why the plugin does:
use base ?;
rather than
use ?
@ISA = ( "?" );

(maybe someone can explain that - I might be doing thing wrong!).

Cheers,
John

There is an other strange thing.
Even if i made a voluntary error in: https://github.com/orazionelson/openaire-compliance/blob/master/cfg/plugins/EPrints/Plugin/Export/DC_Ext.pm<https://github.com/orazionelson/openaire-compliance/blob/master/cfg/plugins/EPrints/Plugin/Export/DC_Ext.pm#L20>

e.g. comment the if statement on line 20:
#if( $eprint->exists_and_set( "eu_project" ) && $eprint->get_value( "eu_project" ) eq "yes" )

and I do NOT comment its closing bracket on line 58

I don't receive any error message on screen: where do I have to look to read errors?

Thanks,
Alfredo

Hello,
It was one of my first doubts.
I tried to comment the IF statement + reload configuration + restart apache

nothing happens :|

thanks,
Alfredo

Hi!

Are sure that this IF statment passes?
https://github.com/orazionelson/openaire-compliance/blob/master/cfg/plugins/EPrints/Plugin/Export/DC_Ext.pm#L20

We are OpenAIRE 3.0 compliant and I will publish the code tomorrow. It's
a bit different solution but you will be able to compare the output part.

Best,
Alen
