Re: [hibernate-dev] Temporary session and commit issue with manual flush mode
Probably openTemporarySession() should be deprecated. Notice it also
says it is for HEM use, though the only current uses I see of it all
come from envers.
If you want to share information from the main session, then the
appropriate access would be to use org.hibernate.SharedSessionBuilder as
obtained from org.hibernate.Session#sessionWithOptions
If the 2 should share JDBC connection, then
org.hibernate.SharedSessionBuilder#connection() should be used. If you
want it to share the entire "transaction context", then
org.hibernate.SharedSessionBuilder#transactionContext() should be used.
Pretty sure I asked Adam and the rest of the list about this
transactionContext() method back when I first added it. I never heard
any response. So if you go that transactionContext() route you may run
into issues because I am pretty sure transactionContext() is sharing too
much.

Hi all,
I have a question regarding SessionFactoryImplementor.openTemporarySession() (bug
HHH-7017). As observed in non JTA environment
with manual flush mode enabled, and 'hibernate.connection.autocommit' disabled,
temporary session is not getting committed.
How/when should I commit it manually? According to JavaDoc, it's
"nontransactional". See the following log (H2):
11:19:01,531 DEBUG SQL:104 - insert into StrTestEntity_AUD (REVTYPE, str, id, REV) values
(?, ?, ?, ?)
11:19:03,687 WARN SqlExceptionHelper:143 - SQL Error: 50200, SQLState: HYT00
Timeout trying to lock table "STRTESTENTITY_AUD"; SQL statement:
select strtestent0_.REV as col_0_0_ from StrTestEntity_AUD strtestent0_ cross join
REVINFO defaultrev1_ where strtestent0_.id=?
and strtestent0_.REV=defaultrev1_.REV order by strtestent0_.REV asc [50200-145]
at
org.hibernate.exception.internal.StandardSQLExceptionConverter.convert(StandardSQLExceptionConverter.java:52)
...
Method AuditProcess.doBeforeTransactionCompletion() is responsible for persisting all
audit data. The description in HHH-7017 is
very accurate and correct. Please advice.
How is temporary session related to current normal session and its lifecycle?

Lukasz
