## GSOC
-### Next large steps, planned:
-
-For all components that have been discovered, in whatever way, we create a service:
- - that's a catalyst component service
- - which is basically just a constructor injection
- - except the constructor name is COMPONENT
- - and we're "implicitly" passing along some constructor args
- - Lifecycle => Singleton
-
- - Fix B::B so that Service::WithParametrs' parameters attribute has a builder
- - Fix ConstructorInjection so that default parameters are supplied (for accept_context_args)
- - Fix ConstructorInjection's 'suffix' - should be called 'config_key' or something, and
- should be an attribute on the service (as it never changes), rather than a parameter
- to the service
-
- - We make a 'components' sub container in the main container.
- - This gets the ConstructorInjection COMPONENT services, as model_Foo.
- - Lifecycle of these services is Singleton
- - This simplifies the code for MyApp->components, as it need only list one sub-container
-
- - We create a second service (depending on the first one) for ACCEPT_CONTEXT
- - This has a custom service which calls ACCEPT_CONTEXT when the instance is fetched
- - Not Singleton lifecycle
-
- Note - ACCEPT_CONTEXT can be called on app values - if you have a Model::Foo, with an ACCEPT_CONTEXT
- and you call MyApp->model('Foo') then ACCEPT_CONTEXT gets invoked with a $c of 'MyApp' (this is not\
- the normal case, but we need to preserve for compat)
+### Final steps for GSOC
+
+##### Things that work:
+
+ - the default container loads all components, calls ACCEPT_CONTEXT() when appropriate, and COMPONENT() when appropriate, behaving like current Catalyst does
+
+ - its possible to create a custom container, and override the components you want. Lifecycle, class, dependencies, all overridable.
+
+ - config files are loaded without Catalyst::Plugin::ConfigLoader
+
+ - per request life cycle somewhat works
+
+ - external modules are loaded just using a custom container, much like Catalyst::Model::Adaptor
+
+##### Things that don't work:
+
+ - expand_component_module
+
+ - loading two containers simultaneously
+
+ - sugar is still not completely implemented
+
+ - Some back compat
+ - wrappers around setup_component, setup_components, locate_components in Catalyst.pm
+ - $instance->expand_modules
+ - search_extra
+ - Crazy tests for things such as:
+ sub COMPONENT {
+ ...
+ *${appclass}::Model::TopLevel::GENERATED::ACCEPT_CONTEXT = sub { ... };
+ ...
+ }
+
+##### Need planning, have questions:
+
+ - per request life cycle
+
+ - sugar - we should discuss the syntax with rafl and edenc
+
+ - when / when not COMPONENT should be called
+
+ - locate_components service vs setup_components method
+ - can we be more lazy?
+ - should setup_components be a service that things like the ->component lookup
+ can depend on?
+
+ - There are a few more FIXMEs, idk if any relevant here
+
+### Next steps - planned:
+
+ - some imports need to get the importing package in Catalyst::IOC
+
+ - test values directly instead of serializing them over http in t/lib/TestCustomContainer.pm
+
+ - 16:01 < shadowpaste> "t0m" at 217.168.150.38 pasted "more explicit? thoughts?" (13 lines) at http://paste.scsys.co.uk/131520
+
+ - Back compat for Catalyst.pm moved methods (locate_components)
+
+ - Test custom container
+ - writing some tests which verify that the models you think should be
+ there are there, and that they received their dependencies as arguments
+ - i.e. Model::Bar should get params { foo => $model_foo } when being
+ constructed, etc
+ - Need to test that if you have a standard component Frotz
+ and a customized component Fnar, and Fnar depends on Frotz
+ - And yeah, some tests that the customised components actually work via
+ $c->model('Foo'), and that COMPONENT is called (or not called)
+ as appropiate and that ACCEPT_CONTEXT is called (or not) as appropriate
### Next steps - less planned:
+ - make ACCEPT_CONTEXT and COMPONENT optional in Catalyst::IOC::BlockInjection and Catalyst::IOC::ConstructorInjection
+ - Create COMPONENTSingleton life cycle
+
- Creating service()-like sugar for component
- Test cases for extending the container in an application.
- Using the sugar added in the previous item
- Test when Model::Foo depends_on Model::Bar
+ - Test for component Foo => ( lifecycle => 'Singleton', class => 'My::External::Class', dependencies => { config => depends_on("config") } )
+ - Fix ^^ so that you can get your component's namespaced config nicely.
+ - Tests for using the container outside of Catalyst
+ - Custom container which adds some (very simple) services which are initialized from
+ the application config file (note plain services, not components)
+ - Depend on (and test) these inside Catalyst
+ - Test loading container outside Catalyst, and these services working
+ - Test Catalyst / MyApp is not loaded
#### Extending my app, notes
package MyApp::Container;
use Catalyst::IOC;
- container $self, as {
+ container $self, as {
container model => as {
component Foo => (); # As per default!
component Bar => (dependencies => ['/model/Foo']); # Magic!
component Baz => ( lifecycle => 'InstancePerContext );
component Quux => ( lifecycle => 'Singleton' ); # ACCEPT_CONTEXT not called
+ # Catalyst::Model::Adaptor example
+ conponent Fnar => ( lifecycle => 'Singleton', class => 'My::External::Class', dependencies => { config => depends_on('config')} );
+ # ^^ FIXME - gets whole config, not Model::Foo
+ # There should be a 'nice' way to get the 'standard' config
};
# Note - implementation of BB may need to be changed to support making sure existing
# services actually get overridden. not sure how the default container behaves when doing that
};

-##### To start with
-
-package MyApp::Container;
-use Moose;
-
-extends 'Catalyst::Container;
-
-after BUILD => sub {
- my $self = shift;
- my $model_container = $self->get_sub_container('model');
- my $service = Catalyst::IOC::ConstructorInjection->new(
- name => 'Baz',
- class => 'MyApp::Model::Baz',
- dependencies => [
- depends_on( '/application_name' ),
- depends_on( '/config' ),
- depends_on( '/model/Foo' ),
- ],
- lifecycle => 'InstancePerContext',
- );
- $model_container->add_service( 'Foo', $service );
-};
-
-### To polish off / t0m review
-
- +Same as L<build_model_subcontainer>, but for controllers. The difference is
- +that there is no ACCEPT_CONTEXT for controllers.
- ^^ This is wrong!!
-
- - my $accept_context_args = $self->param('accept_context_args');
- + my $accept_context_args = $params{accept_context_args};
- ^^ This (may be) wrong! I am thinking the service should be allowed to mangle the
- accept_context args, no?
- Without this change, the user could make a custom service which mangled the param, and use
- Catalyst/IOC/Service/WithAcceptContext.pm, with this change, that module will always see the
- un-mangled version?? However, without this change, shit doesn't work...
-
-### Known issues
-
- - Broken $instance->expand_modules() in setup_components and figure
- out later how to bring it back
-
- - expand_component_module
-
- - People wrapping locate_components in Catalyst.pm
