In some of our Koha:: objects we have methods that cache their result and return it in subsequent calls. However there is no invalidation of the cache if the object is modified.
For instance, in Koha/ArticleRequest.pm
sub biblio {
my ($self) = @_;
$self->{_biblio} ||= Koha::Biblios->find( $self->biblionumber() );
return $self->{_biblio};
}
This pattern exists in several places.
It can lead to confusion and incorrect results, such as:
use Koha::ArticleRequests;
my $ar = Koha::ArticleRequest->new({
borrowernumber => 42,
biblionumber => 42,
})->store;
say $ar->biblio->biblionumber; # Display 42, correct
$ar->set({ biblionumber => 24 })->store;
say $ar->biblio->biblionumber; # Display 42, wrong
$ar->discard_changes;
say $ar->biblio->biblionumber; # Display 42, wrong
$ar->delete;
We should remove those caching and rely on DBIC/DBMS caching mechanism instead.
