The following example code shows that Log4perl's configuration is being
trashed when calling ->deploy(). The failure behaviour is demonstrated
by the lack of a "debug after" debug message.
The Dumper() prints are just for further information.
I suspect that the root cause is the use of Log::Log4perl->easy_init()
by SQL::Translator::Schema::Graph, but I thought I should post it here
first since my example is a DBIC one.
% cat Schema.pm
package Schema;
use warnings;
use strict;
use base qw(DBIx::Class::Schema);
__PACKAGE__ -> load_classes();
1;
% cat Schema/Table.pm
package Schema::Table;
use warnings;
use strict;
use base 'DBIx::Class';
__PACKAGE__->load_components(qw(PK::Auto Core));
__PACKAGE__->table('mytable');
__PACKAGE__->add_columns(id => { data_type => 'integer',
is_auto_increment => 1 });
1;
% cat deploy.pl
use Log::Log4perl;
use Schema;
use Data::Dumper;
my $schema = Schema -> connect("dbi:SQLite:trashme.db");
Log::Log4perl -> init(
{
'log4perl.rootLogger' => 'DEBUG, Screen',
'log4perl.appender.Screen' => 'Log::Log4perl::Appender::Screen',
'log4perl.appender.Screen.stderr' => '1',
'log4perl.appender.Screen.layout' => 'Log::Log4perl::Layout::PatternLayout',
'log4perl.appender.Screen.layout.ConversionPattern' => '[%d] [%p] %m%n',
});
my $log = Log::Log4perl -> get_logger();
print "Before Deploy: ", Dumper($Log::Log4perl::Logger::ROOT_LOGGER);
$log -> debug("debug before");
$schema -> deploy();
$log -> debug("debug after");
print "After Deploy: ", Dumper($Log::Log4perl::Logger::ROOT_LOGGER);
% rm trashme.db; touch trashme.db
% perl deploy.pl
