[Hibernate-JIRA] Created: (HHH-5539) ParameterParser does not support escaped ' symbols

by Alexey Romanchuk (JIRA)

ParameterParser does not support escaped ' symbols -------------------------------------------------- Key: HHH-5539 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5539 Project: Hibernate Core Issue Type: Bug Components: query-sql Affects Versions: 3.6.0.Beta4 Environment: 3.6.0 and postgresql 8.2.1 Reporter: Alexey Romanchuk I create native SQLQuery with createSQLQuery method. Looks like ParameterParser incorrectly process queries with escaped ' symbol. For example query like "select * from a where a.b = 'asdf \' asdf'" works fine, but "select * from a where a.b = 'asdf \' asdf: '" fails with org.hibernate.QueryException: Space is not allowed after parameter prefix ':' 'select * from a where a.b = 'asdf \' asdf'' at org.hibernate.engine.query.ParameterParser.parse(ParameterParser.java:92) at org.hibernate.engine.query.ParamLocationRecognizer.parseLocations(ParamLocationRecognizer.java:75) at org.hibernate.engine.query.QueryPlanCache.buildNativeSQLParameterMetadata(QueryPlanCache.java:149) at org.hibernate.engine.query.QueryPlanCache.getSQLParameterMetadata(QueryPlanCache.java:79) at org.hibernate.impl.AbstractSessionImpl.createSQLQuery(AbstractSessionImpl.java:146) at org.hibernate.impl.SessionImpl.createSQLQuery(SessionImpl.java:1656) -- 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-3608) DB sequence numbers are not unique when using the pooled SequenceStyleGenerator in multiple JVMs with the same DB

by Matthias Gommeringer (JIRA)

DB sequence numbers are not unique when using the pooled SequenceStyleGenerator in multiple JVMs with the same DB ----------------------------------------------------------------------------------------------------------------- Key: HHH-3608 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3608 Project: Hibernate Core Issue Type: Bug Components: core Affects Versions: 3.3.1, 3.3.0.SP1, 3.3.0.GA, 3.2.6 Environment: Hibernate 3.2.6, Oracle (any version) Reporter: Matthias Gommeringer Priority: Blocker Attachments: PooledOptimizerTest.java We have several Application Servers (=JVMs) running each of them using Hibernate-Objects with the SequenceStyleGenerator+pooled configured. In unpredictable time intervals it happens that hibernate assigns the same ID to two completely different objects which results in a UniqueConstraintViolation exception from the database. Here an example with a description where hibernate fails: DB-Sequence setup: start=0 increment=2 PooledOptimizer.generate() with 2 threads (first assignment of hiValue/value): JVM-1 JVM-2 value=0=callback.nextval value=2=callback.nextval hiValue=4=callback.nextval hiValue=6=callback.nextval The problem's cause is in the PooledOptimizer.generate: when it initializes the value+hiValue for the first time it invokes callback.nextValue() twice which may provide values that do not belong to each other. The reason is that between the assignment of "value" and "hiValue" another JVM can retrieve a DB sequence value from the callback which leads to an inconsistent "value" and "hiValue" relation (see example above). A fix that works for multiple JVMs would be to invoke the "callback.getNextValue()" maximum once per "optimizer.generate()" call: public synchronized Serializable generate(AccessCallback callback) { if ( hiValue < 0 ) { value = callback.getNextValue(); hiValue = value + incrementSize; } else if ( value >= hiValue ) { value = callback.getNextValue(); hiValue = value + incrementSize; } return make(value++); } I attached a testcase that prooves the described problem (you can see that the IDs "2" and "3" are assigned two times). I would be very thankful if this problem could be fixed very soon since it is a showstopper which occurs very unpredictably. -- 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-5325) Minor issues in test suite and suggestions for improvements

by Fred Toussi (JIRA)

Minor issues in test suite and suggestions for improvements ----------------------------------------------------------- Key: HHH-5325 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5325 Project: Hibernate Core Issue Type: Improvement Components: testsuite Affects Versions: 3.5.3 Environment: tested with HSQLDB 2.0 Reporter: Fred Toussi Priority: Minor hql:ASTParserLoadingTest : testComponentNullnessChecks() String query = getDialect() instanceof DB2Dialect ? "from Human where cast(? as string) is null" : "from Human where ? is null" The cast should be made by default. DB2 is highly SQL Standard conformant and displays the correct behaviour. (SQL Standard Part 3: Call-Level Interface (SQL/CLI)) Others may "invent" a character type for the dynamic param. ----------------------- legacy:FooBarTest : testFindByCriteria() if(!(getDialect() instanceof TimesTenDialect)) { list = s.createCriteria(Foo.class).setMaxResults(0).list(); assertTrue( list.size()==0 ); } The test produces the equivalent to SQL statements with "FETCH 0 ROWS ONLY" or "LIMIT 0" etc. This is explicitly stated to cause a data exception according to SQL:2008. The row count must be at least 1. ----------------------- org.hibernate.test.hql : Animal.hbm.xml This snippet is used in several tests. Search for "centimeters". <property name="heightInches"> <column name="height_centimeters" not-null="true" read="height_centimeters / 2.54" write="? * 2.54"/> </property> The target SQL column type is created as DOUBLE in most dialects. The dynamic variable in "? * 2.54" first resolves to DECIMAL because the "declared type" of the numeric literal is DECIMAL. It would be better to use "? * 2.54E0" as a hint to use DOUBLE. -- 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-5390) Index column on inverse List should throw a warning

by Chris Bredesen (JIRA)

Index column on inverse List should throw a warning --------------------------------------------------- Key: HHH-5390 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5390 Project: Hibernate Core Issue Type: Improvement Components: annotations Affects Versions: 3.5.3 Reporter: Chris Bredesen The manual correctly warns against trying to map an indexed inverse collection on a List. However, a configuration containing this invalid mapping builds successfully but causes null values to be inserted for the index column. Hibernate should be helpful and, if possible, throw a warning to the user (perhaps an error?) that explains the invalid combination. Here is an example that would run but produce invalid results: @Entity public class Parent { @OneToMany(mappedBy="parent") @OrderColumn(name="order") private List<Child> children; } @Entity public class Child { @ManyToOne private Parent parent; } The above is a typical one to many with the addition of @OrderColumn. Because Child owns the relationship, the index column is lost/ignored. Hibernate should warn 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
