[hibernate-dev] Failing metamodel test categories

2012-12-05 Thread Gail Badner 
I started a wiki page to categorize the failing tests using the new metamodel 
at https://github.com/hibernate/hibernate-orm/wiki/Failing-metamodel-tests.

I'm still in the process of categorizing so you will see a long list at the end 
that still needs to be categorized.

I'll continue with this tomorrow.

Sorry about the formatting. It's too late for me to mess with it. I'll take 
care of it in the morning.

Re: [hibernate-dev] ORM, OGM and timing

2012-12-05 Thread Sanne Grinovero 
Do we need Hibernate 5 to resolve those type system issues?

If so, is there an alternative solution which wouldn't necessarily
couple the OGM lifecycle with ORM ? (just for the time being)

Re: [hibernate-dev] ORM, OGM and timing

2012-12-05 Thread Steve Ebersole 
I am not completely understanding the question.  You don't *need* 
Hibernate 5, you could just plug in a custom QueryTranslatorFactory as 
we discussed on irc.  The discussion here was changing the standard 
QueryTranslatorFactory to use this new Antlr parser.

Re: [hibernate-dev] ORM, OGM and timing

2012-12-05 Thread Sanne Grinovero 
Whether we change the standard QueryTranslatorFactory in ORM doesn't
affect the options we have about releasing OGM, correct Emmanuel?

Let's make sure we can release OGM at any time; having Hibernate ORM
using the new parser by default might cleanup some code but I hope we
can make sure this doesn't affecting functionality.

Re: [hibernate-dev] ORM, OGM and timing

2012-12-05 Thread Sanne Grinovero 
That's what I'm hoping too, but since I've not fully grasped the
proposed solution for the type system I'm not sure: I need to read the
new ORM code.

If we really can just plug a different QueryTranslatorFactory in ORM,
how does this affect our release options on OGM?

Re: [hibernate-dev] ORM, OGM and timing

2012-12-05 Thread Steve Ebersole 
By "type system" do you mean the TypeDescriptor pull request?  If not, 
you'll have to clarify.

If so...

The idea is simple.  There are a number of things that the parser needs 
to know in order to figure out the semantics of the query; this 
question of "types" is just one thing.  However, ORM and OGM have 
different concrete contracts (Type versus GridType) there.  
TypeDescriptor is simply a "bridge" contract that the parser can use in 
making these semantic decisions.  Let's take a few simple examples:

1) ... where p.age + p.birthdate > p.name

Is that a valid restriction?

2) ... from Person p join p.aliases a

Is that a valid join (not as straight forward as I think you think)?

etc

Answering all those questions depends on access to "type information".

I cannot give you exact details on exactly how the parser determines 
"type information" for each expression yet because we still have other 
unanswered questions that affect the answer to that (most notably the 
question of heterogeneous trees versus homogeneous trees).

All, please keep this updated daily, especially if a previously failing test is 
fixed.  It'll really help us keep track of progress.

I started a wiki page to categorize the failing tests using the new metamodel 
at https://github.com/hibernate/hibernate-orm/wiki/Failing-metamodel-tests.

I'm still in the process of categorizing so you will see a long list at the end 
that still needs to be categorized.

I'll continue with this tomorrow.
