-22:16 <@mst> t0m: explain what breaks
-22:16 <@mst> I'm not 100% sure we have the same problem in mind
-22:17 <@t0m> well, various shit in Catalyst utils to resolve app from MyApp::Controller::Foo breaks
-22:17 <@mst> Caelum: http://scsys.co.uk:8001/31240
-22:17 <@mst> t0m: the trick would be to not need to do that
-22:17 <@mst> t0m: $self->_application should be fine
-22:18 <@t0m> $action->class can't be fed back into $c->component()
-22:18 <@t0m> which breaks ::REST
-22:18 <@mst> right
-22:18 <@mst> we need to
-22:19 <@mst> (a) add an ->_component_name or similar method to controllers
-22:19 <@mst> (b) pass action objects either that or the controller
-22:20 <@t0m> do you have a controller calling $action->dispatch? Course you must, the action lives in a controller..
-22:21 <@mst> and that doesn't matter anyway
-22:21 <@mst> dispatch has $c
-22:21 <@mst> it needs to do
-22:21 <@mst> $c->component($self->_component_name)
-22:21 <@mst> and that _component_name needs to come from the controller at register_actions time
-22:22 <@t0m> confound: Oi, please to be releasing my Action::REST fixes, I'm about to do more..
-22:22 <@t0m> mst: right, gotcha
-22:22 <@mst> note that needs to happen in core
-22:22 <@mst> then actions can use that instead of $self->class
-22:22 <@mst> and shit will work
+## throw away the restarter and allow using the restarters Plack provides
- The horrible hack for plugin setup - replacing it:
+## be smarter about how we use PSGI - not every response needs to be delayed
+ and streaming
-15:30 <@mst> t0m: have a look at the Devel::REPL BEFORE_PLUGIN stuff
-15:30 <@mst> I wonder if what we need is that combined with plugins-as-roles

+
+ NOTE - these are notes that t0m thought up after doing back compat for
+ catalyst_component_class, may be inaccurate, wrong or missing things
+ bug mst (at least) to correct before trying more than the first 2
+ steps. Please knock yourself out on the first two however :)
+
+ - Eliminate actions in MyApp from the main test suite
+ - Uncomment warning in C::C::register_action_methods, add tests it works
+ by mocking out the logging..
+ - Remove MyApp @ISA controller (ask metaclass if it has attributes, and if
+ so you need back compat :/)
+ - Make Catalyst::Context, move the per request stuff in there, handles from
+ main app class to delegate
+ - Make an instance of the app class which is a global variable
+ - Make new instance of the context class, not the app class per-request
+ - Remove the components as class data, move to instance data on the app
+ class (you probably have to do this for _all_ the class data, good luck!)
+ - Make it possible for users to spin up different instances of the app class
+ (with different config etc each)
+ - Profit! (Things like changing the complete app config per vhost, i.e.
+ writing a config loader / app class role which dispatches per vhost to
+ differently configured apps is piss easy)
+
+## GSOC
+
+### 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
+
+ - Some back compat
+ - wrappers around setup_component, setup_components in Catalyst.pm
+ - $instance->expand_modules
+ - search_extra
+ - Crazy tests for things such as:
+ sub COMPONENT {
+ ...
+ *${appclass}::Model::TopLevel::GENERATED::ACCEPT_CONTEXT = sub { ... };
+ ...
+ }
+
+##### Items for discussion and planning
+# (in no particular order, just numbered to be more easily refered to)
+
+ 1) per request life cycle
+
+ 2) sugar syntax
+
+ 3) when / when not COMPONENT should be called
+
+ 4) problems when get_all_components() is called when there is no 'context' yet
+
+ 5) Back compat problems:
+ - expand_component_module
+ - $instance->expand_modules
+ - search_extra
+ - what to do when a user overrides the locate_components method?
+
+ 6) 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?
+
+ 7) $class->log->warn is being used to give warnings, but maybe there is a
+ better way to do it
+
+ 8) the ConstructorInjection depends on the application_name, which probably
+ makes app/ctx split harder. We need a way to get the application instance
+ passed properly.
+
+ 9) there is a call in Catalyst::Controller to catalyst_component_name class
+ accessor (which doesn't exist anymore).
+
+ 10) make ACCEPT_CONTEXT and COMPONENT optional in Catalyst::IOC::BlockInjection and Catalyst::IOC::ConstructorInjection
+ - Create COMPONENTSingleton life cycle
+
+ 11) we build the service too early, causing the COMPONENT method to be
+ called early, breaking components which build other components (e.g.
+ Model::DBIC::Schema).
+
+ 12) root service has a very ambiguous name - maybe root_dir?
+
+ 13) should _get_component_type_name (in Catalyst::IOC::Container) exist?
+
+ 14) 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.
+
+ 15) 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
+
+### Next steps
+
+ - Push the config built in the container back up onto the app
+
+ - Find a better way to make path_to work. Current fix is in
+ Catalyst::IOC::Container, subs build_home_service, build_root_service.
+
+ - Improve validation on the 'component' methods in Catalyst::IOC
+ (check the type of the component, etc)
+
+ - Thigs to test:
+ - Imports getting the importing package in Catalyst::IOC
+ - Back compat for Catalyst.pm moved methods (locate_components)
+ - 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
+
+
+#### Extending my app, notes
+
+Basically try to implement something like this (starting out without the sugar!), and see how it breaks
+and what needs to be done to fix it!
+
+##### Eventual syntax
+
+package MyApp::Container;
+use Catalyst::IOC;
+
+ 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
+ component 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
+ # above code would build the constructor injection as it currently does,
+ # defaulting to the class name in the right namespace as declared by the surrounding container
+ # as well as adding using the catalyst-specific service class
+ };
