=head1 NAME
DBIx::QuickORM::Connection::Transaction - One transaction or savepoint on a
DBIx::QuickORM connection.
=head1 DESCRIPTION
Represents a single transaction (or savepoint) and the callbacks queued
against it. C<commit> and C<rollback> record the outcome and break out of the
enclosing C<QORM_TRANSACTION> loop; C<terminate> records the final result and
fires the queued success / fail / completion callbacks. An optional finalize
callback runs when the transaction completes or, as a safety net, when the
object is destroyed while still pending.
=head1 SYNOPSIS
QORM_TRANSACTION: {
my $txn = DBIx::QuickORM::Connection::Transaction->new(id => $id);
$txn->add_success_callback(sub { ... });
...
$txn->commit;
lib/DBIx/QuickORM/Connection/Transaction.pm view on Meta::CPAN
True when this represents a savepoint rather than a top-level transaction.
=item on_success
=item on_fail
=item on_completion
Callback queues (arrayrefs, or a single coderef normalized to one) fired by
C<terminate>. Success or fail callbacks run depending on the outcome,
followed by completion callbacks in both cases.
=item verbose
When true, C<commit> / C<rollback> warn a trace line. A string longer than
one character is used as the transaction name in that warning.
=item result
Undef while open; 1 on success, 0 on failure once terminated.
lib/DBIx/QuickORM/Connection/Transaction.pm view on Meta::CPAN
no warnings 'exiting';
last QORM_TRANSACTION;
}
=pod
=item ($ok, $errors) = $txn->terminate($res, $err)
Records the final result, clears the callback queues and savepoint, then runs
the success-or-fail callbacks followed by the completion callbacks. Returns a
list: a boolean for whether all callbacks succeeded, and an arrayref of any
callback errors (undef when none).

=head1 NAME
DBIx::QuickORM::Manual::Transactions - A guide to transactions in
L<DBIx::QuickORM>.
=head1 DESCRIPTION
This guide covers transactions in L<DBIx::QuickORM>: starting a transaction,
nesting transactions as savepoints, queuing success / fail / completion
callbacks, controlling a transaction by hand, and automatically retrying work
when a connection is lost.
Transactions are controlled through the connection
(L<DBIx::QuickORM::Connection>). Each transaction or savepoint is represented
by a L<DBIx::QuickORM::Connection::Transaction> object.
This is part of the L<DBIx::QuickORM> documentation; see
L<DBIx::QuickORM::Manual> for the documentation hub.
=head1 BASIC TRANSACTIONS
lib/DBIx/QuickORM/Manual/Transactions.pm view on Meta::CPAN
# rolling this back undoes only $bar's insert
});
$baz->insert(...);
}); # commit happens here
Use C<is_savepoint> on a transaction object to tell which kind it is.
=head1 CALLBACKS
You can queue callbacks to run when a transaction finishes. They are fired
after the underlying commit or rollback has been issued.
=over 4
=item on_success
Runs only if the transaction commits.
=item on_fail
lib/DBIx/QuickORM/Manual/Transactions.pm view on Meta::CPAN
Pass them as parameters to C<txn()>:
$con->txn(
on_success => sub { my $txn = shift; ... },
on_fail => sub { my $txn = shift; ... },
on_completion => sub { my $txn = shift; ... },
action => sub { my $txn = shift; ... },
);
You can also queue callbacks against an existing transaction object directly
with C<add_success_callback>, C<add_fail_callback>, and
C<add_completion_callback>.
=head2 PARENT AND ROOT CALLBACKS
When you are inside a nested transaction you can attach callbacks to an outer
transaction instead of the current one. This is useful when a savepoint wants
to defer work until the enclosing transaction actually commits.
The C<on_parent_*> variants attach to the immediate parent transaction; the
C<on_root_*> variants attach to the outermost (root) transaction no matter how
deeply nested you are:
$con->txn(
on_parent_success => sub { ... },
on_parent_fail => sub { ... },
on_parent_completion => sub { ... },
on_root_success => sub { ... },
on_root_fail => sub { ... },
on_root_completion => sub { ... },
action => sub { ... },
);
When there is no parent or root transaction above the current one, the
corresponding parent / root callbacks are simply no-ops.
=head1 LONG-LIVED TRANSACTIONS
If you need a transaction that is not bound to a single callback, call C<txn()>
without an action. It returns a live L<DBIx::QuickORM::Connection::Transaction>
object that you control by hand:
my $txn = $con->txn();
...
$txn->commit; # or $txn->rollback;

=head1 NAME
DBIx::QuickORM::Schema::Autofill - Autofill configuration for schema introspection.
=head1 DESCRIPTION
Holds the type maps, affinity callbacks, and hooks used while autofilling a
schema from a live database. It maps introspected SQL types to
L<DBIx::QuickORM::Type> classes, runs user-supplied hooks at well-known points,
and generates field and link accessors on autovivified row classes.
