| Subject: | Cannot set RootClass attribute to a package in the same file |
Given this example:
--START--
package Foo::DBIx;
our @ISA = qw(DBI);
package Foo::DBIx::db;
our @ISA = qw(DBI::db);
package Foo::DBIx::st;
our @ISA = qw(DBI::st);
package main;
use DBI;
$dbh = DBI->connect(
'dbi:Oracle:', 'scott', 'tiger',
{ RootClass => 'Foo::DBIx' }
);
---END---
DBI (v1.30) throws back the following error:
Can't locate Foo/DBIx.pm in @INC (@INC contains: /home/prod/perl5/lib/5.6.1/aix /home/prod/perl5/lib/5.6.1 /home/prod/perl5/lib/site_perl/5.6.1/aix /home/prod/perl5/lib/site_perl/5.6.1 /home/prod/perl5/lib/site_perl .) at /home/prod/perl5/lib/site_perl/5.6.1/aix/DBI.pm line 776.
...propagated at /home/prod/perl5/lib/site_perl/5.6.1/aix/DBI.pm line 780.
The DBI documentation says that this should be a non-fatal error:
[...] that using an explicit RootClass attribute will make the DBI
automatically attempt to load a module by that name (and not
complain if such a module can't be found) [...]
and code in DBI.pm looks like it tries to ignore this type of error:
sub _load_module {
(my $module = shift) =~ s!::!/!g;
eval {
require $module.'.pm';
};
return 1 unless $@;
return 0 if $@ =~ /^\b\@INC\b/;
die; # propagate $@;
}
But the regex used doesn't match the error thrown back by perl 5.6.1 (the regex itself may be flawed, since '@' !~ /\w/).
If Foo::DBIx is stored in Foo/DBIx.pm, the error isn't thrown.
If the regex is changed to /\@INC\b/, the error also goes away.
Thanks.
