Created: (HHH-2564) StatelessSession query uniquing is inconsist

StatelessSession query uniquing is inconsistent
-----------------------------------------------

                 Key: HHH-2564
                 URL: http://opensource.atlassian.com/projects/hiber
nate/browse/HHH-2564
             Project: Hibernate3
          Issue Type: Improvement
          Components: core
    Affects Versions: 3.2.3
            Reporter: Max Rydahl Andersen


StatelessSession uniquing is inconsistent as in sometimes a
query will use its temporary persistencecontext (introduced
for HHH-1266) to return unique entity instances and in
others it wont.

According to the initial semantics intended (see HHH-742) it
should actually do it for each query.

Main issue is that:

getEntityUsingInterceptor does not check temp
persistencecontext
internalLoad does not check temp persistencecontext nor
create proxies consistent with get()

Max Rydahl Andersen commented on HHH-2564:
------------------------------------------

assume db with 1doc and 2 chapters
"select d from Document d left join d.chapters c"

returns two different Document instances

"select d from Document d left join fetch d.chapters
c"

returns two different Document instances, their chapters
point to the same instances, but chapter.getDocument() point
to two completelty different proxies

"ss.createQuery( "select d from Document d left
join fetch d.chapters c left join fetch c.document"

returns two different Document instances, their chapters
point to the same instances, and chapter.getDocument() point
to two completelty different proxies which in turn point to
the same Document root.
