[Hibernate-JIRA] Created: (HHH-3006) ConcurrentModificationException in AbstractBatcher results in infinite loop

by Stefan Hauk (JIRA)

ConcurrentModificationException in AbstractBatcher results in infinite loop --------------------------------------------------------------------------- Key: HHH-3006 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3006 Project: Hibernate3 Issue Type: Bug Components: core Affects Versions: 3.2.5, 3.2.4.sp1, 3.2.4, 3.2.3 Environment: Hibernate 3.2.5.ga MySQL 5.0.42 Reporter: Stefan Hauk Priority: Minor Here is a piece of code from org.hibernate.jdbc.AbstractBatcher's closeStatements() method: Iterator iter = resultSetsToClose.iterator(); while ( iter.hasNext() ) { try { logCloseResults(); ( (ResultSet) iter.next() ).close(); } catch (SQLException e) { // no big deal log.warn("Could not close a JDBC result set", e); } catch (Throwable e) { // sybase driver (jConnect) throwing NPE here in certain cases log.warn("Could not close a JDBC result set", e); } } resultSetsToClose.clear(); In case there is a ConcurrentModificationException thrown when iterating over the resultSetsToClose HashSet the exception will be caught by the catch(Throwable) clause. However, the iteration may continue infinitely because of the corrupted HashSet. This pegs one CPU and logs the following stack trace over and over again: 28/11 20:16:50 WARN AbstractBatcher [resin-tcp-connection-myserver:6001-15] Could not close a JDBC result set java.util.ConcurrentModificationException at java.util.HashMap$HashIterator.nextEntry(HashMap.java:841) at java.util.HashMap$KeyIterator.next(HashMap.java:877) at org.hibernate.jdbc.AbstractBatcher.closeStatements(AbstractBatcher.java:314) at org.hibernate.jdbc.ConnectionManager.cleanup(ConnectionManager.java:382) at org.hibernate.jdbc.ConnectionManager.close(ConnectionManager.java:324) at org.hibernate.impl.SessionImpl.close(SessionImpl.java:298) at org.springframework.orm.hibernate3.SessionFactoryUtils.closeSession(SessionFactoryUtils.java:774) at org.springframework.orm.hibernate3.support.OpenSessionInViewFilter.closeSession(OpenSessionInViewFilter.java:252) at org.springframework.orm.hibernate3.support.OpenSessionInViewFilter.doFilterInternal(OpenSessionInViewFilter.java:183) at org.springframework.web.filter.OncePerRequestFilter.doFilter(OncePerRequestFilter.java:75) at com.caucho.server.dispatch.FilterFilterChain.doFilter(FilterFilterChain.java:70) at com.caucho.server.cache.CacheFilterChain.doFilter(CacheFilterChain.java:188) at com.caucho.server.webapp.WebAppFilterChain.doFilter(WebAppFilterChain.java:178) at com.caucho.server.dispatch.ServletInvocation.service(ServletInvocation.java:229) at com.caucho.server.hmux.HmuxRequest.handleRequest(HmuxRequest.java:419) at com.caucho.server.port.TcpConnection.run(TcpConnection.java:389) at com.caucho.util.ThreadPool.runTasks(ThreadPool.java:492) at com.caucho.util.ThreadPool.run(ThreadPool.java:425) at java.lang.Thread.run(Thread.java:595) The catch(Throwable) block was added in Hibernate 3.2.3 if I saw that correctly. Apparently the reason was to catch a NPE thrown by a sybase driver here, but catching Throwable catches more than that and produces this side-effect. Now I do realize that the ConcurrentModificationException might be caused by not using Hibernate in a correct way, but I haven't determined the cause for it yet. However, I do think that Hibernate should fail more gracefully than it currently does. -- 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-2980) Error "org.hibernate.HibernateException: cannot simultaneously fetch multiple bags" not specific enough

by Dobes Vandermeer (JIRA)

Error "org.hibernate.HibernateException: cannot simultaneously fetch multiple bags" not specific enough ------------------------------------------------------------------------------------------------------- Key: HHH-2980 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2980 Project: Hibernate3 Issue Type: Improvement Affects Versions: 3.2.5 Reporter: Dobes Vandermeer When I get this exception: org.hibernate.HibernateException: cannot simultaneously fetch multiple bags I don't know what to do except google. Why not spruce it up a little to say something like: For class X, multiple collection fields are marked for eager fetching: a, b, c; this is not supported by Hibernate in releases after 3.2.x -- 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-3191) QueryPlanCache cache size

by Julien Kirch (JIRA)

QueryPlanCache cache size ------------------------- Key: HHH-3191 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3191 Project: Hibernate3 Issue Type: Improvement Components: query-hql Affects Versions: 3.2.6 Environment: Hibernate 3.2.6, all platform Reporter: Julien Kirch On a large application with many (currently 696) named queries in hbm files we have a performance issue with the QueryPlanCache cache size: The SoftLimitMRUCache used in the QueryPlanCache use 128 hard references, the other being soft references, and this number is hardcoded. As we have much more querries in the application, we spend much time in recompiling the same queries when they are evicted from the cache. As the QueryPlanCache has a SessionFactoryImplementor as parameter, adding a new parameter to define the query cache plan size would be trivial; what's your opinion about this ? -- 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-2431) QueryPlanCache grows without bound. Eventually gets OutOfMemoryException

by Eric Goff (JIRA)

QueryPlanCache grows without bound. Eventually gets OutOfMemoryException -------------------------------------------------------------------------- Key: HHH-2431 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2431 Project: Hibernate3 Type: Bug Components: core Versions: 3.2.2 Environment: all versions, all platforms Reporter: Eric Goff Every time you execute a query, and that query does not match any existing queries in the QueryPlanCache, that query is *always* added to the Query Plan Cache, along with a lot of various antlr stuff. There seems to be no way to control it. Minimally, there should be some sort of heap of query plans where the least used query plan is ejected when the cache reaches it max size. The cache size should, of course, be user configurable. -- 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: (HBX-1000) Problem with PostgreSQL using uppercase letters in tables

by Ruediger Engelberger (JIRA)

Problem with PostgreSQL using uppercase letters in tables --------------------------------------------------------- Key: HBX-1000 URL: http://opensource.atlassian.com/projects/hibernate/browse/HBX-1000 Project: Hibernate Tools Issue Type: Bug Components: reverse-engineer Affects Versions: 3.2.beta11 Environment: Hibernate 3.2.5.ga, Hibernate Tools 3.2.0 beta9a, PostgreSql 8.2, postgresql-8.2-506.jdbc3.jar, Eclipse 3.3.0, all running on Windows XP at the moment (including PostgreSql) Reporter: Ruediger Engelberger I have problems using Hibernate tools when using upper case letters in a PostgreSQL database. I can configure Hibernate Tools for my local PostgreSql installation without any problems. I can access the table structure in the view Hibernate Configurations and do reverse engineering by creating XML mappings and beans. No problem. But when I'm using upper case characters in table names Hibernate Tools can't access the table structures any more. Hibernate Configuration shows the tables, but when I want to see the columns, it doesn't show anything. Reverse engineering also doesn't work any more. So, the following works: TABLE cms_clusterMessage pk_clustermessageid fk_clusternodeid messagetype messagedetail The following doesn't work: TABLE cms_clusterMessage PK_ClusterMessageId FK_ClusterNodeId MessageType MessageDetail I tried to use different JDBC drivers because I thought it could be a bug of the driver. But it wasn't. -- 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

by Nicolae Bucalaete (JIRA)

There is no annotation to specify default value for a column ------------------------------------------------------------ Key: ANN-604 URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-604 Project: Hibernate Annotations Issue Type: Bug Affects Versions: 3.3.0.ga Reporter: Nicolae Bucalaete Priority: Critical In hibernate annotation you can't specify default value for a column. If you use xml files for mapping then you have this feature. I consider that this is a major problem with annotation. -- 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
