[Hibernate-JIRA] Created: (HHH-2169) L2 Cache and Long transactions Memory Leak : OutOfMemoryException

by Sami Dalouche (JIRA)

L2 Cache and Long transactions Memory Leak : OutOfMemoryException ----------------------------------------------------------------- Key: HHH-2169 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2169 Project: Hibernate3 Type: Bug Components: core Versions: 3.2.0.ga Environment: [b]Hibernate version:[/b] Hibernate Entity Manager 3.2.0, with Hibernate Core 3.2.0 and Hibernate Annotations 3.2.0 [b]Mapping documents:[/b] Annotations [b]Full stack trace of any exception that occurs:[/b] Memory Heap Exception [b]Name and version of the database you are using:[/b] PosgreSQL 8.1 Reporter: Sami Dalouche Summary --------- When enabling L2 Cache (with either OScache and EhCache, both with a limitation on the max #of instances, so the problem shouldn't come from the cache manager), Hibernate cannot have long running transactions, otherwise, it results in a Memory Heap Exception... The problem does NOT happen if the L2 Cache is disabled ! Details ---------- - Configure the code to run in ONE transaction - Have a huge loop that inserts 2 million entries that are cacheable (@Cache(usage = CacheConcurrencyStrategy.NONSTRICT_READ_WRITE)) - flush() and clear() every 1000 entries, to periodically flush the cache => None of the entries are garbage collected. => Using a profiler, it is possible to trace the owning objects of my domain classes to : - org.hibernate.action.EntityInsertAction ("instance" variable) - array / List (variable elementData) - variable "executions" in object .. class org.hibernate.engine.ActionQueue Remarks : - If the Query Cache is disabled, and the objects being inserted are NOT cacheable (no @Cache annotation), there is no problem - If the Query Cache is enabled, then, no matter whether the objects being inserted are cacheable or not, The entries are never garbage collected, and I get an OutOfMemoryException. (I see NO relationship between the Query Cache and my objects. I never query the objects, only save them !!) -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira

[Hibernate-JIRA] Créée: (HHH-2389) Improving DB2 dialect

by Nicolas Billard (JIRA)

Improving DB2 dialect --------------------- Key: HHH-2389 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2389 Project: Hibernate3 Type: Improvement Components: query-hql Versions: 3.2.1 Environment: Development based on v 3.2.1 Reporter: Nicolas Billard Priority: Minor Attachments: DB2Dialect.java The class joined to this issue overrides the DB2 dialect. The dialect included in hibernate doesn't work very well when you want to limit returned results (when you call setFirstResult and / or setMaxResults on a query) : - the instructions "fetch first XXX row only is not used - a temporary table is used when it's not usefull - when you have subselects, an exception can occur if subselects have order by clause (because of the getRowNumber method, not corrected here). This version of getLimitString() method generates faster requests (tests made on a table of 300000 rows shows that fetching rows from 20 to 30 takes 0.3 seconds with original version, 0.02 with this one). -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira

[Hibernate-JIRA] Created: (HHH-1994) Problem with case sensitive column and tables names and Identity mapping with postgreSQL

by Alex Samad (JIRA)

Problem with case sensitive column and tables names and Identity mapping with postgreSQL ---------------------------------------------------------------------------------------- Key: HHH-1994 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-1994 Project: Hibernate3 Type: Bug Components: core Versions: 3.1.3 Environment: Hibernate 3.1.3, Java 1.5.0_07 (sun) windos and linux ( 32 & 64 bit). POstgres SQL 8.1 Windows and linux Reporter: Alex Samad Whilst trying to insert into a table with a primary key (ID mapping) which has a identity generator. And the columns and/or the table has been defined with case sensitivey ie back ticks. It fails to get the next serial number and thus fails any inserts. The problem lies in dialect/PostgreSQLDialect.java public String getIdentitySelectString(String table, String column, int type) { return new StringBuffer().append("select currval('") .append(table) .append('_') .append(column) .append("_seq')") .toString(); } table is inclosed in quotes and column is inclosed in quotes which gives a name like "table"_"Column"_seq - which fails I would suggest a fix is to test each of table or column for " and if it exist then to strip it of both of table and column and encluse the whole name in "". This mighe break some old code where say the table is coded in case insensitive table name and case sensitive column key.

[Hibernate-JIRA] Created: (HHH-2893) Criteria api does not allow a groupProperty to _NOT_ be included in the selected columns

by Antony Stubbs (JIRA)

Criteria api does not allow a groupProperty to _NOT_ be included in the selected columns ---------------------------------------------------------------------------------------- Key: HHH-2893 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2893 Project: Hibernate3 Issue Type: Bug Affects Versions: 3.2.5 Environment: n/a Reporter: Antony Stubbs When adding a Projections.groupProperty("prop") to a criteria, the property is added to both the GROUP BY and SELECT parts of the generated SQL query. This is a major problem for using the criteria API for complex subselects that require aggregating by a column while grouping by another column. There is presently no way in the criteria API to group by a column and have it _ONLY_ in the GROUP BY clause. i.e. currently Projections.groupProperty("propOne") causes: SELECT propOne, MAX(propTwo) FROM table GROUP BY prop desired option is to have SELECT MAX(propTwo) FROM table GROUP BY prop There have been several people talking about this, but there appears to have been 'no comment'. http://forum.hibernate.org/viewtopic.php?t=939071&highlight=values+groupp... http://forum.hibernate.org/viewtopic.php?t=950803&highlight=groupproperty... http://forum.hibernate.org/viewtopic.php?t=964512&highlight=groupproperty... http://forum.hibernate.org/viewtopic.php?t=957671&highlight=groupproperty... http://forum.hibernate.org/viewtopic.php?p=2317841#2317841 http://forum.hibernate.org/viewtopic.php?t=961617&highlight=groupproperty...

[Hibernate-JIRA] Created: (HHH-2473) fetch="join" and property-ref

fetch="join" and property-ref ----------------------------- Key: HHH-2473 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2473 Project: Hibernate3 Type: Improvement Versions: 3.2.1 Environment: Version 3.2.1, not DB dependant Reporter: David CLEMENT When Hibernate does a fetch join with a property-ref in a many-to-one, it issues the join SQL query but needs another select to find the associated entity by property-ref. It should be able to use the entity fetched in the join instead (maybe this has been done to ensure the unicity of the associated entity, but it introduce a performance issue). -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira
