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.

On bug 17591 we discovered that there was something weird going on with
the way we export and use subroutines/modules.
This patch tries to standardize our EXPORT to use EXPORT_OK only.
That way we will need to explicitely define the subroutine we want to
use from a module.
This patch is a squashed version of:
Bug 17600: After export.pl
Bug 17600: After perlimport
Bug 17600: Manual changes
Bug 17600: Other manual changes after second perlimports run
Bug 17600: Fix tests
And a lot of other manual changes.
export.pl is a dirty script that can be found on bug 17600.
"perlimport" is:
git clone https://github.com/oalders/App-perlimports.git
cd App-perlimports/
cpanm --installdeps .
export PERL5LIB="$PERL5LIB:/kohadevbox/koha/App-perlimports/lib"
find . \( -name "*.pl" -o -name "*.pm" \) -exec perl App-perlimports/script/perlimports --inplace-edit --no-preserve-unused --filename {} \;
The ideas of this patch are to:
* use EXPORT_OK instead of EXPORT
* perltidy the EXPORT_OK list
* remove '&' before the subroutine names
* remove some uneeded use statements
* explicitely import the subroutines we need within the controllers or
modules
Note that the private subroutines (starting with _) should not be
exported (and not used from outside of the module except from tests).
EXPORT vs EXPORT_OK (from
https://www.thegeekstuff.com/2010/06/perl-exporter-examples/)
"""
Export allows to export the functions and variables of modules to user’s namespace using the standard import method. This way, we don’t need to create the objects for the modules to access it’s members.
@EXPORT and @EXPORT_OK are the two main variables used during export operation.
@EXPORT contains list of symbols (subroutines and variables) of the module to be exported into the caller namespace.
@EXPORT_OK does export of symbols on demand basis.
"""
If this patch caused a conflict with a patch you wrote prior to its
push:
* Make sure you are not reintroducing a "use" statement that has been
removed
* "$subroutine" is not exported by the C4::$MODULE module
means that you need to add the subroutine to the @EXPORT_OK list
* Bareword "$subroutine" not allowed while "strict subs"
means that you didn't imported the subroutine from the module:
- use $MODULE qw( $subroutine list );
You can also use the fully qualified namespace: C4::$MODULE::$subroutine

As failure situations raise exceptions that should be handled outside
the object class, methods should return $self so successive calls can be
chained nicely.
This patch makes methods return $self and adjusts the tests to reflect
this change.
Make sure tests pass:
- Run:
$ prove t/db_dependent/Koha/Patron/Attribute/Types.t
=> SUCCESS: Tests return green

This patch introduces a new class for extending Koha::Object using
multiple inheritance. It cannot be used standalone, it needs to be
used in Koha::Object implementations like this:
use base qw( Koha::Object Koha::Object::Limit::Library );
Its goal is to provide a single way and place to deal with this common
pattern in Koha's codebase.
As it happened with Koha::Object, that needed to be tested in a real object
class, this work was done on top of Koha::Patron::Attribute::Type implementation
and it is fully covered by the tests that are introduced for it.
