+0.24 Wed May 27 17:55:50 UTC 2009
- Add tests for issues with Class::C3 which are caused to
applications which use new Catalyst but old DBIC, and have
use Class::C3 in the MyApp class (t0m)
- die on empty schema
- create=dynamic deprecation warning
- conversion to Moose
- - cursor caching support (via ::Role::Caching)
- - ::Storage::Replicated support (via ::Role::Replicated)
+ - cursor caching support (via ::Trait::Caching)
+ - ::Storage::Replicated support (via ::Trait::Replicated)
- switch to hashref connect_info for DBIC 8100
- better helper option parsing, with support for more options
- helper passes loader opts to dynamic schemas

-Array of Traits to apply at BUILD time. Traits are relative to the

-namespaces, unless prefixed with C<+> in which case they are taken to be a
-fully qualified name. E.g.:
+Array of Traits to apply to the instance. Traits are L<Moose::Role>s.

traits Caching
traits +MyApp::DB::Trait::Foo
-This is done using L<MooseX::Object::Pluggable>.
-
A new instance is created at application time, so any consumed required
attributes, coercions and modifiers will work.
Traits are applied before setup, schema and connection are set.
-C<ref $self> will be an anon class if any traits are applied.
+C<ref $self> will be an anon class if any traits are applied, C<<
+$self->_original_class_name >> will be the original class.
-You cannot modify C<new> or C<BUILD>, modify C<setup> instead.

-L</ACCEPT_CONTEXT> and L</finalize> can also be modified.
+You cannot modify C<BUILD> in a trait, as that is when traits are applied,
+modify L</setup> instead.
