[Hibernate-JIRA] Created: (HSEARCH-383) Hibernate Search does not respect the @AccessType annotation in respect to @Id fields.

Hibernate Search does not respect the @AccessType annotation in respect to @Id fields.
--------------------------------------------------------------------------------------
Key: HSEARCH-383
URL: http://opensource.atlassian.com/projects/hibernate/browse/HSEARCH-383
Project: Hibernate Search
Issue Type: Bug
Components: engine
Affects Versions: 3.1.1.GA, 3.1.0.GA
Environment: Hibernate 3.3.1.GA
Reporter: Steven Knock
Priority: Minor
Attachments: TestAccessTypeProblem.java
This occurs when indexing an Entity annotated as @IndexedEmbedded if the object that it is @ContainedIn is a proxy object that has not yet been loaded and if the @AccessType of the @Id of the proxy object has been overriden from field to property.
This is because Hibernate Search does not respect the @AccessType annotation, and so attempts to read the id of the parent object directly from the member variable, which is not initialised in the proxy and so returns 0 in the attached test case.
The problem is in:
org.hibernate.search.engine.DocumentBuilderIndexedEntity.checkDocumentId().
This results in a record in the Lucene index that has no reference to the containing instance. So, while the number of results is returned correctly, any attempt to actually retrieve the results and convert them into Hibernate objects fails.

[Hibernate-JIRA] Created: (HSEARCH-402) Provide a ReaderProvider to cap the number of index reopenings to a fixed rate

Provide a ReaderProvider to cap the number of index reopenings to a fixed rate
------------------------------------------------------------------------------
Key: HSEARCH-402
URL: http://opensource.atlassian.com/projects/hibernate/browse/HSEARCH-402
Project: Hibernate Search
Issue Type: New Feature
Reporter: Sanne Grinovero
Assignee: Sanne Grinovero
Fix For: 3.2.0
It's often unneeded to recheck for an index update at very high frequency, which ends up to be a bottleneck in high-throughput applications
for an unneded guarantee of having latest version of index.
Setting a configurable period, let's say 5 seconds, will make this ReaderProvider reopen an IndexReader once each 5 seconds.
This can be done in background, removing the delay of checks from the call to openReader(); and enabling index warmup in future (Lucene 2.9 feature) in background.
When reopening in background the ratio will be fixed, i.e. the index will be reopened even if there's no request for a new IR.
This impl should manage the timer, but otherwise delegate to another implementation of ReaderProvider (defaulting to current default: SharingBufferReaderProvider) to optionally chain and provide the benefits of the other implementation.

[Hibernate-JIRA] Created: (HHH-2844) Limit and 'For Update' do not work on Oracle
by Michael Kopp (JIRA)
Limit and 'For Update' do not work on Oracle
--------------------------------------------
Key: HHH-2844
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2844
Project: Hibernate3
Issue Type: Bug
Components: query-sql
Affects Versions: 3.2.2
Reporter: Michael Kopp
Limits on oracle lead too:
select * from (select x.y as xy_1 from table x) where rownum <= 5
when doing a for update that leads too
select * from (select x.y as xy_1 from table x) where rownum <= 5 for update of x.y
The problem is that the x.y is invalid and not found within the temporary view and leads to an oracle error.
what would be valid is the name of the view column xy_1, meaning
select * from (select x.y as xy_1 from table x) where rownum <= 5 for update of xy_1
Actually this should be valid in all cases when doing a alias for update lock.
My Solution thus was to override the following in my own Oracle Dialect
public String applyLocksToSql(final String sql, final Map aliasedLockModes, final Map keyColumnNames)
{
final String s = new ForUpdateFragment(this, aliasedLockModes, keyColumnNames)
{
@Override
public ForUpdateFragment addTableAlias(final String alias)
{
// search for alias in sql
final int i = sql.indexOf(alias);
// check if the found string is followed by an ' as ' and thus has a column alias
if (i != -1 && sql.length() > (i + alias.length() + 4) && sql.substring(i + alias.length(), i + alias.length() + 4).equals(
" as "))
{
// use the column alias
return super.addTableAlias(sql.substring(i + alias.length() + 4, sql.indexOf(',',i + alias.length() + 4)));
}
return super.addTableAlias(alias);
}
}.toFragmentString();
return sql + s;

[Hibernate-JIRA] Created: (HBX-939) Composite IDs and many-to-many relationships

Composite IDs and many-to-many relationships
--------------------------------------------
Key: HBX-939
URL: http://opensource.atlassian.com/projects/hibernate/browse/HBX-939
Project: Hibernate Tools
Issue Type: Bug
Affects Versions: 3.2beta9
Environment: Hibrnate 3.2.1, Postgresql 8.1.8
Reporter: Markus Kramer
Attachments: B.hbm.xml, testdb.sql
The detection of many-to-many relationships doesn't work correctly if the primary key of one of the involved tables consists of more than one field.
An example:
One of two tables (table 'A') of a many-to-many relationship has a primary key consisting of two attributes (id1 and id2).
The generated B.hbm.xml for the table 'B' contains this:
<set name="as" inverse="true" table="a_b">
<key>
<column name="b_id" not-null="true" />
</key>
<many-to-many entity-name="test.A">
<column name="a_id1" not-null="true" />
</many-to-many>
</set>
But there should be another entry for the referenced primary key:
<column name="a_id2" not-null="true" />
The SQL code for the used tables and the complete B.hbm.xml are attached.

[Hibernate-JIRA] Created: (HHH-3129) Null Role in PersitentCollection during a onCollectionRecreate() in an Interceptor

Null Role in PersitentCollection during a onCollectionRecreate() in an Interceptor
----------------------------------------------------------------------------------
Key: HHH-3129
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3129
Project: Hibernate3
Issue Type: Bug
Components: core
Affects Versions: 3.2.6
Environment: Any
Reporter: Jose CHILLAN
When the "onCollectionRecreate" is invoked on an Interceptor, the getRole() method returns null. After investigation,
the problem is located in the class CollectionEntry in one of its constructors and is easily solved using the patch :
public CollectionEntry(CollectionPersister persister, PersistentCollection collection)
{
// new collections that get found + wrapped
// during flush shouldn't be ignored
ignore = false;
collection.clearDirty(); //a newly wrapped collection is NOT dirty (or we get unnecessary version updates)
snapshot = persister.isMutable() ? collection.getSnapshot(persister) : null;
// -- ADDED LINE HERE --
role = persister.getRole();
collection.setSnapshot(loadedKey, role, snapshot);
}
Thanks

THIS_"."NAME": invalid identifier when using createCriteria with addOrder
-------------------------------------------------------------------------
Key: HHH-2847
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2847
Project: Hibernate3
Issue Type: Bug
Components: query-criteria
Affects Versions: 3.0.5
Environment: Oracle - 10.2.0
Reporter: Ashish Tiwari
We are using hibernate 3.0.5 and once a while I see following error getting generated due to incorrect SQL generated by hibernate:
Hibernate: select systembean0_.SYSTEMID as SYSTEMID12_0_, systembean0_.Version as Version12_0_, systembean0_.NAME as NAME12_0_, systembean0_.TYPE as TYPE12_0_, systembean0_.DESCRIPTION as DESCRIPT5_12_0_ from SDSYSTEM systembean0_ order by this_.NAME asc
- SQL Error: 904, SQLState: 42000
- ORA-00904: "THIS_"."NAME": invalid identifier
This normally works but occasionally we run into the issue mentioned above. I do not see alias "this_" in the sql query and I think that causes the error to happen. Issue is caused by alias not used consistently.
In normal case the generated SQL looks like following:
Hibernate: select this_.SYSTEMID as SYSTEMID7_0_, this_.Version as Version7_0_, this_.NAME as NAME7_0_, this_.TYPE as TYPE7_0_, this_.DESCRIPTION as DESCRIPT5_7_0_ from SDSYSTEM this_ order by this_.NAME asc
I am not sure what causes this problem. Has anyone else see similar problem earlier?
I appreciate any help with this. Below is other information:

[Hibernate-JIRA] Created: (HHH-3345) "select new" + "join fetch" = "owner of the fetched association was not present in the select list"
by Anthony Ogier (JIRA)
"select new" + "join fetch" = "owner of the fetched association was not present in the select list"
---------------------------------------------------------------------------------------------------
Key: HHH-3345
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3345
Project: Hibernate3
Issue Type: Bug
Affects Versions: 3.2.4.sp1
Reporter: Anthony Ogier
I want to create a List<B>, each B containing an entity with "A" type, and I also want for each A to force fetching of its "C" property.
public class B {
private A a;
public B(A a) {
this.a = a;
}
}
@Entity
public class A {
@ManyToOne @JoinColumn
private C c;
// +get/setter ...
}
@Entity
public class C {
@Column
private String d;
// +get/setter ...
// +@OneToMany
}
Here is the HQL :
select new B(a) from A a left join fetch a.c
I have that message :
org.hibernate.QueryException: query specified join fetching, but the owner of the fetched association was not present in the select list
When invoking only "from A a left join fetch a.c", all is good and I have ma List<A> with its "C" properties fetched.
I think there is a little bug here ... or did I forget something ?
