-Known issues:
+# Known Bugs:
-Documentation:
+ - Bug ->go or ->visit causes actions which have Args or CaptureArgs called
+ twice when called via ->go or ->visit.
- - Catalyst/Upgrading.pod needs brushing up
+ Test app: http://github.com/bobtfish/catalyst-app-bug-go_chain/tree/master
- - Warning when you pass $c->model("MyApp::Model::Foo") is the generic
- warning for regex fall back. Should be more specific about what you
- screwed up, and the docs for $c->model should be more explicit about
- what is expected. This probably also applies to view/controller.
+# Compatibility warnings to add:
-Profiling:
+ - $self->config should warn as config should only ever be called as a
+ class method (TESTS).
- - vs 5.70 and optimisation as needed.
+# Proposed functionality / feature additions:
+
+## Log setup needs to be less lame
+
+So Catalyst::Plugin::Log::* can die
+in a fire. Having $c->log_class would be a good start. kane volunteered
+to do some of this.
+
+Simple example: Catalyst::Plugin::Log::Colorful should just be a
+subclass of Catalyst::Log, no ::Plugin:: needed.
+

+# REFACTORING
+
+## The horrible hack for plugin setup - replacing it:
+
+ * Have a look at the Devel::REPL BEFORE_PLUGIN stuff
+ I wonder if what we need is that combined with plugins-as-roles
+
+## App / ctx split:
+
+ 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)

+
+### 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)
+
+### Next steps - less planned:
+
+ - 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
+
+ - 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
+
+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
+ };
+ # 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
+ };
+
+1;
+
+##### 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
