Hey Chisel,
I've been writing a whole lot of T::DBIC::Schema tests recently and I've
come across an issue where tables with many rows (> 4M in my case) give
an OOM memory as the column test calls get_column on all rows of the table.
I've come up with a tweak that should resolve this, as well as making
the test quite a lot faster... apologies for not sending you a diff
(lazy Darius), but here's the tweak:
On line 136 replace:
my $col = $rs->get_column($method)->all;
with
my $col = $rs->slice(0,0)->get_column($method)->all;
Basically just adds a limit 1 to the query.
Hope you can get it onto CPAN before the next release!
Cheers,
Darius
