[EP-tech] Re: Errors when requesting /id/eprint/$eprintid after 3.3.13 update

No, it's not just you - I just found and solved the same error about half an hour ago!

If you replace the line 897 with

if( $self->scope == CRUD_SCOPE_DATAOBJ || $self->scope == CRUD_SCOPE_USER_CONTENTS )

that fixed it for me.

Subject: [EP-tech] Errors when requesting /id/eprint/$eprintid after 3.3.13 update

Hi,

I updated my repository to EPrints 3.3.13 on January 28 (two days after the Debian package was made available). I have not realized until now, but since that moment, all URLS of the form http://$myhost/id/eprint/$eprintid generate an "Internal Server Error"
page. As an example, this page works correctly:

    http://ru.iiec.unam.mx/2633/

But this one fails:

    http://ru.iiec.unam.mx/id/eprint/2633

In my error.log file, I get:

    [Tue Feb 17 10:42:43 2015] [error] [client 132.248.72.141] Can't call method "base_id" on an undefined value at /usr/share/eprints3/perl_lib/EPrints/Apache/CRUD.pm line 897.\n

And yes, I checked my logs, and the first such message occured just after I performed the update. I am attaching a screencapture from the Google Tools for Webmasters showing the number of errors.

This error happens in the content_negotiate_best_plugin function, regardless of what parameters I give to it; it seems to be related to not having a defined database object — The specific line it complains on is:

    if( ( $self->scope == CRUD_SCOPE_DATAOBJ && $self->{database}->base_id ne "subject" ) || $self->scope == CRUD_SCOPE_USER_CONTENTS )

The database connection *is* working, but it might not yet be initialized at this point in the request handling. Besides, either commenting out the check for $self->{database}->base_id or making it conditional on having defined $self->{database} make the problem apparently go away.

So:

1. Does this happen to others, or is it just me?
2. Does my ugly fix break something else?
3. What goes here? :)

Thanks,
