[Hibernate-JIRA] Created: (ANN-841) Bidirectional indexed collection mapped incorrectly for IndexedCollectionTest

by Gail Badner (JIRA)

Bidirectional indexed collection mapped incorrectly for IndexedCollectionTest ----------------------------------------------------------------------------- Key: ANN-841 URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-841 Project: Hibernate Annotations Issue Type: Bug Reporter: Gail Badner Assignee: Emmanuel Bernard Attachments: TEST-org.hibernate.test.annotations.indexcoll.IndexedCollectionTest.xml I believe that two bidirectional associations with indexed collections that use join tables are mis-mapped for org.hibernate.test.annotations.indexcoll.IndexedCollectionTest. Mappings in AddressBook: @MapKey @OneToMany(mappedBy = "book", cascade = {CascadeType.MERGE, CascadeType.PERSIST, CascadeType.REMOVE}) @JoinTable(name="AddRegEntry") public Map<AddressEntryPk, AddressEntry> getEntries() { return entries; } @MapKey(name = "directory") @OneToMany(mappedBy = "book") @JoinTable(name="Dir_Entry") public Map<AlphabeticalDirectory, AddressEntry> getDirectoryEntries() { return directoryEntries; } Mappings in AddressEntry: @ManyToOne public AddressBook getBook() { return book; } @ManyToOne public AlphabeticalDirectory getDirectory() { return directory; } AddRegEntry and Dir_Entry are not generated in the DDL and the CRUD operations do not reference the join tables. Test output is attached. -- 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-902) Support naming / renaming HQL editor tabs

by Joseph Marques (JIRA)

Support naming / renaming HQL editor tabs ----------------------------------------- Key: HBX-902 URL: http://opensource.atlassian.com/projects/hibernate/browse/HBX-902 Project: Hibernate Tools Type: New Feature Versions: 3.2beta8 Reporter: Joseph Marques Right now, if I open multiple HQL editors under the same configuration they are ALL named "HQL: <configuration>" When I have 3 or 4 of them open, I sometimes forget which query is in which, so I waste time poking around to find the right one. If they could be suffixed with the unique user-chosen token, then they would be much easier to work with. So something like: "HQL: <configuration>: <name>" Or, even better, since HQL isn't really needed (because the HQL editor has a distinct editor icon), it could be removed entirely, leaving us with: "<configuration>: <name>" Thoughts? -- 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-2399) FlushMode.AUTO practically unusable - should not flush before EVERY query

by Piotr Kołaczkowski (JIRA)

FlushMode.AUTO practically unusable - should not flush before EVERY query ------------------------------------------------------------------------- Key: HHH-2399 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2399 Project: Hibernate3 Type: Improvement Versions: 3.1.3, 3.2.1, 3.2.2, 3.2.0.ga Environment: PostgreSQL 8.1.5, JDBC 2 and 3, Linux kernel 2.4.x, 2.6.x, Java 1.5.0_09 Reporter: Piotr Kołaczkowski Attachments: hbtest.zip The method flushIfRequired seems to flush before every query execution, even though there wasn't anything changed to the objects in the session, and the objects in the session are of different class than the object(s) queried. When having more than a few such objects in a session, it may lead to large, unneeded overheads (I noticed 10-200 times slowdown on simple queries). Our system uses many fast queries, that uasually return only one result or few results. The average query durations on different levels, measured by System.nanoTime() (see the attachment): - database level: 0.05 ms - pure JDBC code, prepared statements: 0.2 ms - pure JDBC code, no prepared statements: 0.7 ms - not cached hibernate query, no other objects associated with the session: 1.3 ms - cached hibernate query, object in the session cache, no other objects associated with the session: 1.1 ms - cached hibernate query, 10000 very simple objects of some other class in the session: >50 ms 10000 may seem large, but note these were very simple objects, having only 2 properties. On our production system we have classes with many properties, and even 20 objects in a session can cause a sub-millisecond query to run longer than 5 ms. We switched to FlushMode.COMMIT, and now the performance is much better. Can you do something about this? As far as I've read in JIRA, a similar issue exists in Hibernate 2.x, and is still OPEN / UNRESOLVED. BTW. Why is the 1st level cache so slow in my tests? Why reading just a 2 field object from the database cause so much overhead over pure JDBC? What am I doing wrong? There is so much marketing about using cglib reflection optimizer in the performance FAQ but even if I retrieved these objects using JDBC and reflection, I would achieve much better performance. After all 1 ms is very much time, if getting results from DB and sending them to JVM lasts 0.2 ms. -- 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-2347) Improvement to DerbyDialect default identy generation mode

by Fabrizio Giustina (JIRA)

Improvement to DerbyDialect default identy generation mode ---------------------------------------------------------- Key: HHH-2347 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2347 Project: Hibernate3 Type: Patch Versions: 3.2.1 Reporter: Fabrizio Giustina Attachments: DerbyDialect-identity.diff although derby supports identities org.hibernate.dialect.DerbyDialect strangely uses an HiLo generation strategy for ids (for any other dialects that support identities IdentityGenerator is the default). Even more curiously, DerbyDialect overrides getIdentityColumnString() from the Db2 dialect by using "generated ALWAYS as identity" instead of "generated BY DEFAULT as identity". Derby however fully supports "by default" in identities as clarified in http://db.apache.org/derby/docs/10.1/ref/rrefsqlj37836.html . "by default" should be preferred since it allows a direct insertion when needed (and I can't see no reason why enabling it for db2 and not for derby). The patch attached simply deletes two methods, so that the default implementation from Db2Dialect is used: - removing getIdentityColumnString() make derby use "by default" identities like db2 already does - removing getNativeIdentifierGeneratorClass() make it choose IdentityGenerator.class (it falls back to the default strategy used in org.hibernate.dialect.Dialect) note that part of this issue has already been reported in HHH-1918 (not addressing the identity generation string) -- 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-3391) DerbyDialect should support limits

by Marijo (JIRA)

DerbyDialect should support limits ---------------------------------- Key: HHH-3391 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3391 Project: Hibernate3 Issue Type: New Feature Components: core Environment: Apache Derby 10.4.1.3 Reporter: Marijo >From Apache Derby FAQ http://db.apache.org/derby/faq.html#limit "Starting with the 10.4.1.3 release Derby also supports limiting the number of rows using the ROW_NUMBER function."

using @LOB annotation --------------------- Key: ANN-797 URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-797 Project: Hibernate Annotations Issue Type: Bug Reporter: Patrick Walter When I use the @LOB annotation it always creates only VARCHAR(255) for stringData and Binary (255) for binaryData defined below. @Lob @Basic(fetch=FetchType.LAZY) private byte[] binaryData; @Lob @Basic(fetch=FetchType.LAZY) private String stringData; Any help in resolving this would be VERRY!!! appreciated.
