[Dbix-class] undef vs. {}

[Christopher H. Laco]

I have a resultset question. Is this by design, or by accident?


This fails

  $schema->resultset('Carts')->search(undef, undef);

with:

> Use of uninitialized value in anonymous hash ({}) at C:/strawberry-perl/p=
erl/site/lib/DBIx/Class/ResultSet.pm line 190.
> DBIx::Class::ResultSet::search(): DBD::SQLite::db prepare_cached failed: =
near "IS": syntax error(1) at dbdimp.c line 269
>  at C:/strawberry-perl/perl/site/lib/DBIx/Class/Storage/DBI.pm line 978.

This succeeds:

  $schema->resultset('Carts')->search(undef, {});

They're both equally futile when written manually. But in things like
Handel, where I'm simply passing @_ down the line to DBIC search

  sub search {
    my $self =3D shift;
    magic...

    $schema->resultset('Carts')->search(@_);
  }

  $handel->search($filter, $options);


It's pita to check  @_ for undefs, and strip them out, rather than
having DBIC just ignore them...

Of course, I could be off my rocker...
