Hi Tim,

#!/usr/bin/perl
# script to delete all history records and revisions
use strict;

use FindBin;
use lib "$FindBin::Bin/../perl_lib";

use EPrints;

my $repo = EPrints->new->repository($ARGV[0]);

$repo->dataset( "history" )->search( staff => 1 )->map(sub {
     my (undef, undef, $hist) = @_;
     if ( my $file_rec = $hist->stored_file( "dataobj.xml" ) ) {
         print $file_rec->get_value("fileid"), " gelöscht.\n";
         $file_rec->remove;
     }
     $hist->EPrints::DataObj::remove();
});

After running it, the revisions are still there, e.g.
archives/$REPOID/documents/disk0/00/00/00/88/revisions/6.xml

Running it again, no records to remove are found.

Hence, WHAT exactly has been deleted here? :-)


Regards,
FH
