I'd like to keep the types in MusicBrainz::Entity::Types, since they won't cover other classes
2009-04-19 10953, 2009

MusicBrainz::Entity::Types then, heh

2009-04-19 10919, 2009
luks
just 'use Moose' doesn't seem enough
2009-04-19 10921, 2009
aCiD2
have you used Moose::Util::TypeConstraints?
2009-04-19 10930, 2009
aCiD2
that's where subtype and class_type are
2009-04-19 10950, 2009

thanks
2009-04-19 10915, 2009

heh, now the types are short, I'm tempted to put the has commands back to a single line
2009-04-19 10937, 2009
aCiD2
Heh, did you know you can have multiple attributes to one has?
2009-04-19 10944, 2009
aCiD2
has [qw/foo bar/] => ( ... )
2009-04-19 10910, 2009
aCiD2
if we're sure we won't need to put extra constraints on attributes like traits, metaclasses, whatever - then just stick them on one line
2009-04-19 10915, 2009
luks
I've seen it in your example from the mail first time
2009-04-19 10933, 2009

I just expand them from personal prepreference

prepreference? preference*
2009-04-19 10903, 2009

would be nice if the Collection::Array metaclass, when using provides => { push => 'add_stuff' }, automatically called the item class constructor if I pass it just a plain hash
it knows the item has to be MusicBrainz::Server::Entity::ArtistCreditName
2009-04-19 10905, 2009
aCiD2
You could use coercion to get that
2009-04-19 10934, 2009
aCiD2
corce 'Whatever' => from 'HashRef' => via { Foo->new{$_) }
2009-04-19 10940, 2009
luks
yeah, but the metaclass could handle that automatically
2009-04-19 10943, 2009
aCiD2
yea
2009-04-19 10946, 2009
aCiD2
i agree
2009-04-19 10903, 2009
aCiD2
but I think add can take a list, so it wouldn't know whether you give it a hash or a list of items

oh, right

from what I can see, it isn't used anywhere
2009-04-19 10928, 2009
aCiD2
Nope, I can't find any references to $c->cache either
2009-04-19 10932, 2009
aCiD2
do you want to remove it?
2009-04-19 10928, 2009

I don't know yet, I'd like to not make cache dependant on catalyst
2009-04-19 10941, 2009
aCiD2
yea, i agree with that
2009-04-19 10942, 2009

but if the plugin does somethign useful, we might want to keep it

what I wanted was to make some kind of Context object, with access to the database and cache, which can by used by tests and console scripts
2009-04-19 10929, 2009
aCiD2
something that maintains handles?
2009-04-19 10930, 2009

and MusicBrainz::Server would inherit this, to make it available to the catalyst context too

luks
yes
2009-04-19 10958, 2009

mmm, I can't see any other way to do, and to get testing working easily too

aCiD2: one problem with the code is that it's not easily testable
2009-04-19 10932, 2009
luks
aCiD2: unit testing should test the simplest possible units
2009-04-19 10959, 2009
luks
aCiD2: so you should have tests for loading from the database, loading from the cache, serialization/deserialization
luks: hrm, actually i'd argue it is *more* testable. If you want to make sure the right cache keys are set, make a mock using 'with CacheAccessor' and a mock cache implementation (provide from/to_cache)
2009-04-19 10951, 2009
aCiD2
but I haven't tried, so I'm most likely talking nonsense :)
2009-04-19 10911, 2009

aCiD2: how are you going to test the path of Artist::load which is loading directly from the database?

Give a mock cache implementation that returns undef, so it won't use the cache?

how do you give it a mock cache implementation?
2009-04-19 10903, 2009
aCiD2
oh right, heh
2009-04-19 10916, 2009
aCiD2
how do you do it in yours?
2009-04-19 10924, 2009
luks
it's easier to have Artist class which only works with the database
2009-04-19 10927, 2009
luks
no cache involved
2009-04-19 10940, 2009
aCiD2
Oh, well I wasn't sure where you added the caching layer
2009-04-19 10945, 2009
luks
then you have a subclass, which caches te requests

no, not every entity is cacheable

ah, right
2009-04-19 10921, 2009

I wonder how places like amazon deal with the exchange rates for usa/canada... I mean, for british people they're not going to go look at .fr or .de for something cheaper 'cause they're not in english, and .com would involve quite slow/expensive shipping in comparison to .uk

There's a table which stores whether it's an album or a single.
