package MyApp::Schema;
use parent 'DBIx::Schema';
__PACKAGE__->ensure_class_loaded('DBIx::Class::Storage::TxnEndHook');
__PACKAGE__->ensure_class_loaded('DBIx::Class::Storage::DBI');
__PACKAGE__->inject_base('DBIx::Class::Storage::DBI', 'DBIx::Class::Storage::TxnEndHook');

DESCRIPTION

DBIx::Class::Storage::TxnEndHook is transaction hook provider for DBIx::Class. This module is porting from DBIx::TransactionManager::EndHook.

METHODS

• $schema->storage->add_txn_end_hook(sub{ ... })

  Add transaction hook. You can add multiple subroutine and transaction is not started, cant call this method. These subroutines are executed after all transactions are commited. If any transaction is failed, these subroutines are cleard.

  If died in subroutine, warn deid message and clear remain all subroutines. It is different from DBIx::Class::Storage::TxnEndHook. In DBIx::TransactionManager::EndHook, when died in subroutine, other subroutines are canceld and died.

  Why ? It's caused by DBIx::Class::Storage::TxnScopeGuard. Guard object marked inactivated after $self->{storage}->txn_commit in DBIx::Class::Storage::TxnScopeGuard::commit. So if died in here, can't mark guard as inactivated.
