API differences in Hibernate ORM 5.1 vs 5.3
by Gail Badner
Hi,
There were lots of differences in the compatibility report, so as a first
step, I've excluded packages/classes that I considered SPI, internal, or
"grey area". This reduced the the differences to a more manageable amount.
You can see a summary of the incompatibilities along with suggested
mitigation at [1].
The report is attached to [1], along with a zip with instructions for
running the report.
I believe there are some "false positives" in the report, and I have
documented them in the section, "False Positives?".
Feel free to comment on the article.
Thanks,
Gail

IP banned from forum
by Gunnar Morling
Hi,
Is anyone banning users from the forum? I am getting "A ban has been
issued on your IP address."
I don't think banning by IP is a good strategy as many users will have
dynamic IPs from their hoster's shared pool, so it's a random game to
hit an IP previously banned due to some other user's spam.
Thanks,

New CI machine preview
by Sanne Grinovero
You're all welcome to play with http://54.225.162.168/
however please keep these in mind:
- it's not the final machine: don't put too much effort in creating
nice build scripts as we'll reset it to clean state soon. We *might*
be able to store jobs defined so far, but we might choose not to.
- domain name should be coming: ci.hibernate.org ..not sure when, got
no replies so far from.
- authentication: just click on login, it will use OAuth2 to request
your identity via your GitHub account. Permissions to create new jobs,
edit existing jobs, run a build manually depend on your github account
be part of the Hibernate organization (or not, in which case you have
read only status)
At this stage I'd like to get a feeling if the hardware is powerful
enough, and also we need to select which other plugins we want to use,
I'm looking especially to:
- static analysis reports
- pull requests integration
both are relatively undefined, we can of course start simple and
improve later.. just checking this fits basic needs now.

Unable to release :(
by Steve Ebersole
I ran the 6.0 Alpha5 release. All the tasks completed fine except I was
not able to upload the "dist" to Sourceforge nor the docs to JBoss. All
artifacts are pushed to BinTray.

Re: [hibernate-dev] run a single unit test speed up?
by Jason Pyeron
I got it down to BUILD SUCCESSFUL in 2m 32s
27 actionable tasks: 5 executed, 22 up-to-date
By using
./gradlew :hibernate-core:test --tests org.hibernate.test.annotations.cid.CompositeIdFkGeneratedValueIdentityTest
Package___________________________ Tests Duration Success rate
org.hibernate.test.annotations.cid 1____ 0.586s__ 100%
For an approximate 250x slow down compared to the test execution, sigh.

Trying to understand the significance and use of the sequence methods in Dialect
by Jason Pyeron
Other than the javadocs, are these documented anywhere?
* public String getSequenceNextValString(String sequenceName)
* public String getSelectSequenceNextValString(String sequenceName)
I have been following their usage throughout the codebase, but it is not easy.
Is getSequenceNextValString only used in place of single values? E.g. INSERT INTO NEW_USER VALUES (SEQ_USER.NEXTVAL, 'Adams', 'John') ? Or are there other uses?
Is getSelectSequenceNextValString only used to get the "batch" for Hibernate's future issuance of ids?
The reason I am asking is we would like to leverage the MS SQL Server's sp_sequence_get_range . By using the approach of using the stored procedure for Hibernate's allocation and otherwise using an increment by 1 allows higher efficiency with the Hibernate based application and prevent breaking legacy access to the table/use of the sequence. This topic was unclearly broached in HHH-10130. Internet research below...
Take the following example:
CREATE SEQUENCE [dbo].[hibernate_sequence2]
AS [bigint]
START WITH 1
INCREMENT BY 1
CACHE 200
;
CREATE TABLE [MyTable2]
(
[ID] [bigint] PRIMARY KEY NOT NULL DEFAULT (NEXT VALUE FOR [dbo].[hibernate_sequence2]),
[Title] [nvarchar](64) NOT NULL
);
insert into MyTable2 (Title) values ('test 1');
insert into MyTable2 (Title) values ('test 2');
insert into MyTable2 (Title) values ('test 3');
insert into MyTable2 (Title) values ('test 4');
select * from MyTable2;
--ID Title
--1 test 1
--2 test 2
--3 test 3
--4 test 4
DECLARE @range_first_value_output sql_variant ;
declare @range_size int=50+1;
DECLARE @sequence_increment sql_variant ;
declare @range_last_value sql_variant;
EXEC sys.sp_sequence_get_range
@sequence_name = N'[dbo].[hibernate_sequence2]'
, @range_size = @range_size
, @range_first_value = @range_first_value_output OUTPUT
, @sequence_increment = @sequence_increment OUTPUT
, @range_last_value = @range_last_value OUTPUT ;
SELECT @range_first_value_output AS FirstNumber, @sequence_increment as sequence_increment, @range_last_value as range_last_value ;
--FirstNumber sequence_increment range_last_value
-- 5 1 55
insert into MyTable2 (Title) values ('test 5');
select * from MyTable2;
--ID Title
--1 test 1
--2 test 2
--3 test 3
--4 test 4
--56 test 5
I know there are issues of "knowing" the @SequenceGenerator(allocationSize), but I will assume a fixed 50 for now.

Re: [hibernate-dev] [hibernate/hibernate-orm] HHH-10956 test cases and fix (#3368)

JPA 2 spec 2.4.1.3 Examples of Derived Identities,
Case (a): The dependent entity uses IdClass to represent a composite key:
```
public class DependentId {
String name; // matches name of @Id attribute
long emp; // matches name of @Id attribute and type of Employee PK
}
@Entity
@IdClass(DependentId.class)
public class Dependent {
@Id String name;
// id attribute mapped by join column default
@Id @ManyToOne Employee emp;
...
}
```
HeadS is the Entity type and its Id type is Long.
I backed out the changes to SimpleValue.java/AbstractEntityTuplizer.java and changed the IdClasses to match and it does pass the tests in Hibernate.
But when testing 2.4.1.3, case a without the patch the following tests fails:
- testCompositePkWithIdentityAndFKByAuto: No part of a composite identifier may be null
- testCompositePkWithIdentityAndFKByAuto2: No part of a composite identifier may be null
- testCompositePkWithIdentityAndFKBySequence: No part of a composite identifier may be null
- testCompositePkWithIdentityAndFKBySequence2: No part of a composite identifier may be null
- testCompositePkWithIdentityAndFKByTable: No part of a composite identifier may be null
- testCompositePkWithIdentityAndFKByTable2: No part of a composite identifier may be null
These tests are expected to fail / ignored:
- testCompositePkWithIdentityAndFKByIdentity: No part of a composite identifier may be null
- testCompositePkWithIdentityAndFKByIdentity2: skipped
