updated TODO for psgi

[catagits/Catalyst-Runtime.git] / TODO

# Known Bugs:

   - Bug ->go or ->visit causes actions which have Args or CaptureArgs called
     twice when called via ->go or ->visit.

     Test app: http://github.com/bobtfish/catalyst-app-bug-go_chain/tree/master

# Compatibility warnings to add:

  - $self->config should warn as config should only ever be called as a
    class method (TESTS).

# 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

##  PSGI

###  Blockers

  * Fix nginx middlewares so that they are generic, or can somehow
    be used by people with their own .psgi files
  * Fix a sane / nicer way to do custom engines.

  * I've noticed a small difference with Catalyst::Test. The latest stable
    version include two headers, 'host' and 'https'. They are missing from
    this version.

  * Installation issues with some common modules (from Task::Catalyst)
      - Catalyst::ActionRole::ACL (test failures, fix in repo:
        https://github.com/bobtfish/catalyst-actionrole-acl/pull/1)
      - Catalyst::Plugin::Session::Store::DBIC ( test failure because of
        change to the way Test::Catalyst works, fix in repo at:
        http://dev.catalystframework.org/svnweb/Catalyst/revision?rev=14058)
      - Catalyst::Engine::HTTP::Prefork ?? maybe remove from Task::Catalyst?
      - CatalystX-SimpleLogin : will work once we fix Catalyst::ActionRole::ACL.

#### Script survey

###  Nice to have

  * Capture arguments that the plack engine component was run with somewhere,
    to more easily support custom args from scripts (e.g. Gitalist's 
    --git_dir)
  * throw away the restarter and allow using the restarters Plack provides
  * remove per-request state from the engine instance
  * be smarter about how we use PSGI - not every response needs to be delayed
    and streaming

##  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)
