[Hibernate-JIRA] Created: (HHH-3919) Hibernate uses DROP TABLE to drop temporary tables - it should use DROP TEMPORARY TABLE

by Donnchadh O Donnabhain (JIRA)

Hibernate uses DROP TABLE to drop temporary tables - it should use DROP TEMPORARY TABLE --------------------------------------------------------------------------------------- Key: HHH-3919 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3919 Project: Hibernate Core Issue Type: Bug Components: query-hql Affects Versions: 3.3.1 Environment: MySQL 5.0.77 Reporter: Donnchadh O Donnabhain DROP TABLE requires DROP TABLE permission whereas DROP TEMPORARY TABLE doesn't. Currently the drop command is hardcoded as "drop table " in AbstractStatementExecutor.java (line 177). Something like getFactory().getDialect().getDropTemporaryTableString() is needed. -- 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: (ANN-794) Polymorphic query on abstract function

by radu (JIRA)

Polymorphic query on abstract function -------------------------------------- Key: ANN-794 URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-794 Project: Hibernate Annotations Issue Type: Bug Affects Versions: 3.3.0.ga Reporter: radu Priority: Blocker I have the following classes adnnotated with hibernate: <pre><code> @Entity @Inheritance(strategy=InheritanceType.JOINED) public abstract class Symbol implements Serializable { @Id @GeneratedValue(strategy = GenerationType.AUTO) private Integer id; @AccessType("property") public abstract String getCode(); @AccessType("property") public abstract void setCode(String code); } @javax.persistence.Entity @AttributeOverride( name="code", column = @Column(name="field1") ) public class Child1 extends Symbol { @Basic @Column(nullable = false) private String field1; @AccessType("property") public String getCode() { return getField1(); } @AccessType("property") public void setCode(String code) { setField1(code); } public void setField1(String field1) { this.field1 = field1; } public String getField1() { return field1; } } @javax.persistence.Entity @AttributeOverride( name="code", column = @Column(name="field2") ) public class Child2 extends Symbol { @Basic @Column(nullable = false) private String field2; @AccessType("property") public String getCode() { return getField2(); } @AccessType("property") public void setCode(String code) { setField1(code); } public void setField1(String field2) { this.field2 = field2; } public String getField2() { return field2; } } </code></pre> As objectual rules about polymorphisms the following query should be valid and to retrieve correct field value: session.createQuery("from Symbol s where s.code = :code"); but it give me the error: org.hibernate.QueryException: could not resolve property: code of: ... Please give some advices how to work around this problem if this situation does not follow hibernate concept or JPA specs and is not possible to implement it. Idea is that it should be possible to work at hight level without changing database or existing classes.

[Hibernate-JIRA] Created: (HHH-4095) bug in org.hibernate.Hibernate.createBlob( InputStream in )

by Stephan Schröder (JIRA)

bug in org.hibernate.Hibernate.createBlob( InputStream in ) ----------------------------------------------------------- Key: HHH-4095 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-4095 Project: Hibernate Core Issue Type: Bug Components: core Affects Versions: 3.3.2 Environment: (doesn't matter because ii's just a plain wrong usage of the InputStream.available-mehtode but anyway:) Hibernate. 3.3.2, Hsqldb1.8 Reporter: Stephan Schröder Priority: Minor The implementation of org.hibernate.Hibernate.createBlob( InputStream in ) looks like this public static Blob createBlob(InputStream stream) throws IOException { return new SerializableBlob( new BlobImpl( stream, stream.available() ) ); } The second parameter here is supposed to be the length of the inputstream. The problem is that stream.available() doesn't return the length of the inputstream. That's explicitly noted in the Java-API (http://java.sun.com/javase/6/docs/api/java/io/InputStream.html#available): "Note that while some implementations of InputStream will return the total number of bytes in the stream (on calling available() ), many will not. It is never correct to use the return value of this method to allocate a buffer intended to hold all data in this stream." This is the source of my problem, only the first available bytes are read out of the inputstream. While the workaround for me is to simply call org.hibernate.Hibernate.createBlob( InputStream in,int length ), the misuse of stream.available() in Hibernate.createBlob( InputStream in ) remains to be resolved. Solution: the only way to get the length of an InputStream ist to read it completly, if you don't want to do that Hibernate.createBlob( InputStream i ) should be removed. (By the way, why is length of type int? java.io.File.length() and java.sql.Blob.length() are of type long, so length should be of type long as well). -- 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-2967) Cast to date in Formula still doesn't work

by Frederic Leitenberger (JIRA)

Cast to date in Formula still doesn't work ------------------------------------------ Key: HHH-2967 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2967 Project: Hibernate3 Issue Type: Bug Components: query-criteria, query-hql, query-sql Affects Versions: 3.2.5 Environment: Hibernate-Version: 3.2.5.ga Oracle 9i/10g Reporter: Frederic Leitenberger Priority: Minor Similar to HHH-473. Oracle 10g supports trunc(TS). (TS is a timestamp) Oracle 9i only supports trunc(cast(TS as date)) [and 10g supports this still too]. Therefore i need to add the cast to the Forumla. @Basic @Column(nullable = false, updatable = false) @Temporal(TemporalType.TIMESTAMP) public Date getCreated() { return created; } public void setCreated(Date created) { this.created = created; } @Formula(value = "trunc(cast(created as date))") public Date getDate() { return date } public void setDate(Date date { this.date= date } This results in the following query: select eventlog0_.id as id9_0_, eventlog0_.created as created9_0_, ......... trunc(cast(eventlog0_.created as eventlog0_.date)) as formula6_0_ from ICCS6.EventLog eventlog0_ where eventlog0_.id=? The alias in front of "date" is obviously misplaced there. I also tried renaming the formula (since it was called "date"), but this didn't change the result. -- 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-3236) Prevent classloader leaks to JBC and JGroups when using a shared cache

by Brian Stansberry (JIRA)

Prevent classloader leaks to JBC and JGroups when using a shared cache ---------------------------------------------------------------------- Key: HHH-3236 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3236 Project: Hibernate3 Issue Type: Sub-task Components: caching (L2) Reporter: Brian Stansberry Assignee: Brian Stansberry Fix For: 3.3.0 JGroups spawns a number of threads when a channel is created. JBC can spawn an eviction thread as well. A newly spawned thread inherits its thread context classloader from the thread that spawned it. If a shared JBC CacheManager is used (e.g. in an appserver) it is important to set the TCCL away from any application classloader and to the CacheManager's TCCL before starting a cache. This ensures that the application classloader doesn't leak to any JBC or JGroups threads. -- 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 Ed Burns (JIRA)

validateValue incorrectly reports java.lang.IllegalArgumentException: Invalid property path. There is no property listOfString in entity simple_bv_servlet.Person ----------------------------------------------------------------------------------------------------------------------------------------------------------------- Key: BVAL-175 URL: http://opensource.atlassian.com/projects/hibernate/browse/BVAL-175 Project: Bean Validation Issue Type: Bug Affects Versions: 4.0.0.Alpha2 Environment: HEAD of JSR-303 RI Reporter: Ed Burns Calling validator.validateValue() seems to fail when it shouldn't. Consider this pojo: 8<---------------------------------- package simple_bv_servlet; import java.util.List; import javax.validation.constraints.NotNull; public class Person { @NotNull private String firstName; public String getFirstName() { return firstName; } public void setFirstName(String firstName) { this.firstName = firstName; } @NotNull private String lastName; public String getLastName() { return lastName; } public void setLastName(String lastName) { this.lastName = lastName; } private List<String> listOfString; public List<String> getListOfString() { return listOfString; } public void setListOfString(List<String> listOfString) { this.listOfString = listOfString; } } 8<---------------------------- And consider this selvlet which validates this pojo in its doGet() impl. 8<-------------------------------------- package simple_bv_servlet; import java.io.IOException; import java.io.PrintWriter; import java.util.ArrayList; import java.util.List; import java.util.Set; import javax.servlet.ServletException; import javax.servlet.http.HttpServlet; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import javax.validation.ConstraintViolation; import javax.validation.Validation; import javax.validation.ValidatorContext; import javax.validation.ValidatorFactory; public class SimpleBVServlet extends HttpServlet { @Override protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException { PrintWriter out = resp.getWriter(); resp.setContentType("text/html"); out.print("<html><head><title>SimpleBVServlet</title></head><body>"); ValidatorFactory validatorFactory = null; validatorFactory = Validation.buildDefaultValidatorFactory(); out.print("<p>"); out.print("Obtained ValidatorFactory: " + validatorFactory + "."); out.print("</p>"); ValidatorContext validatorContext = validatorFactory.usingContext(); javax.validation.Validator beanValidator = validatorContext.getValidator(); out.print("<h1>"); out.print("Validating invalid person class using validateValue."); out.print("</h1>"); List<String> value = new ArrayList<String>(); value.add("one"); value.add("two"); value.add("three"); Set<ConstraintViolation<Person>> violations = beanValidator.validateValue(Person.class, "listOfString", value); if (violations.isEmpty()) { out.print("<p>"); out.print("No ConstraintViolations found."); out.print("</p>"); } else { for (ConstraintViolation<Person> curViolation : violations) { out.print("<p>"); out.print("ConstraintViolation: message: " + curViolation.getMessage() + " propertyPath: " + curViolation.getPropertyPath()); out.print("</p>"); } } Person person = new Person(); out.print("<h1>"); out.print("Validating invalid person instance using validate."); out.print("</h1>"); violations = beanValidator.validate(person); if (violations.isEmpty()) { out.print("<p>"); out.print("No ConstraintViolations found."); out.print("</p>"); } else { for (ConstraintViolation<Person> curViolation : violations) { out.print("<p>"); out.print("ConstraintViolation: message: " + curViolation.getMessage() + " propertyPath: " + curViolation.getPropertyPath()); out.print("</p>"); } } out.print("<h1>"); out.print("Validating valid person."); out.print("</h1>"); person.setFirstName("John"); person.setLastName("Yaya"); violations = beanValidator.validate(person); if (violations.isEmpty()) { out.print("<p>"); out.print("No ConstraintViolations found."); out.print("</p>"); } else { for (ConstraintViolation<Person> curViolation : violations) { out.print("<p>"); out.print("ConstraintViolation: message: " + curViolation.getMessage() + " propertyPath: " + curViolation.getPropertyPath()); out.print("</p>"); } } out.print("</body></html>"); } } 8<------------------------ The call to Set<ConstraintViolation<Person>> violations = beanValidator.validateValue(Person.class, "listOfString", value); causes this exception to be thrown: java.lang.IllegalArgumentException: Invalid property path. There is no property listOfString in entity simple_bv_servlet.Person But I say, doch, there is such a property on the Person. This is new behavior in 4.0.0.Beta2, and it's breaking Glassfish.

[Hibernate-JIRA] Created: (ANN-825) TestCase could check for superclass of Dialect before skipping it

by Juraci Paixao Krohling (JIRA)

TestCase could check for superclass of Dialect before skipping it ----------------------------------------------------------------- Key: ANN-825 URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-825 Project: Hibernate Annotations Issue Type: Improvement Reporter: Juraci Paixao Krohling Assignee: Hardy Ferentschik Attachments: ANN-CheckSuperclassDialectsBeforeSkip.diff If a subclass of org.hibernate.test.annotations.TestCase is annotated with @RequiresDialect (or any of its methods), TestCase tries to match the exact name of the dialect in order to decide to skip it or not. My suggestion (and the attached patch) adds another check. If I specify the superclass of a set of dialects (like Oracle8iDialect, which is superclass of Oracle9i and Oracle10g), the test won't skip the subclasses of Oracle8iDialect. How to reproduce: 1) Create a test case annotated with @RequiresDialect(Oracle8iDialect.class) 2) Configure the test to run using the Oracle9iDialect 3) The test will be skipped, even though Oracle9iDialect is a subclass of Oracle8iDialect After the patch, the step 3 would be: 3) The test is not skipped. If there's a reason to not check the superclasses, please reject this JIRA. Otherwise, please review it and commit (or assign it back to me to commit). -- 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
