[Hibernate-JIRA] Created: (HBX-812) Fetching Children of Database _crawls_.

by Syd Poetry (JIRA)

Fetching Children of Database _crawls_. --------------------------------------- Key: HBX-812 URL: http://opensource.atlassian.com/projects/hibernate/browse/HBX-812 Project: Hibernate Tools Type: Bug Components: reverse-engineer Versions: 3.2beta8 Environment: MySQL 5.0, Eclipse 3.2, JDK 1.5, Beta8 for Hibernate Tools Reporter: Syd Poetry I just updated a bunch of components for Eclipse (mostly related to Visual Editor); added a couple of tables to my database, went to regenerate all the POJO clases .hbm.xml mapping files, and found that anything that queries the database schema runs abysmally slow. Updated the tools from beta6 to beta8 thinking it might be a conflict with one of the updates that was performed, still very slow (5+ minutes to retrieve a list of tables!). Deleted all my hibernate-related XML files thinking it might be a parsing error, went to generate a new console file, and revenge.xml, found out that any listbox that tried to access the schema appeared to be hanging. It finishes after much hard-drive crunching. I have 2.2 GBs free running windows XP, MEM usage is 856 MB out of 1.5 GB physical memory. Just out of curiousity, is *anyone* else having this slow response for schema detection? I'm wondering if I have to update another component like a driver or something like that. -- 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-2983) Properties of a Map key not consistently populated before being put into the Map

by Dobes Vandermeer (JIRA)

Properties of a Map key not consistently populated before being put into the Map -------------------------------------------------------------------------------- Key: HHH-2983 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2983 Project: Hibernate3 Issue Type: Bug Components: core Affects Versions: 3.2.5 Environment: Glassfish v2 b58, PostgreSQL 8.2, running in Windows XP Reporter: Dobes Vandermeer I'm getting weird behavior where my map correctly has two entries when fetched as part of a list, and only one entry when I fetch it using EntityManager.get(). Here's an abbreviated version of the mapping for the class that contains the Map: @Entity(name="Account") public class Account implements Comparable<Account>, SecurityChecks { private Long id; private Map<Currency, Balance> balances = new HashMap<Currency, Balance>(); // Current balance in each currency public Account() { } @Id @GeneratedValue public Long getId() { return id; } public void setId(Long id) { this.id = id; } @OneToMany(cascade={CascadeType.ALL}, mappedBy="account") @MapKey(name="currency") public Map<Currency, Balance> getBalances() { return balances; } public void setBalances(Map<Currency, Balance> balances) { this.balances = balances; } } And the class that it contains: @Entity(name="Balance") @Table(uniqueConstraints={@UniqueConstraint(columnNames={ "account_id", "currency_id" })}) public class Balance implements SecurityChecks { private Long id; private Account account; private Currency currency; private long amount; @ManyToOne(cascade=CascadeType.PERSIST, optional=false) public Account getAccount() { return account; } public void setAccount(Account account) { this.account = account; } @Column(nullable=false) public long getAmount() { return amount; } public void setAmount(long amount) { this.amount = amount; } @ManyToOne(cascade=CascadeType.PERSIST, optional=false) @JoinColumn(name="currency_id") public Currency getCurrency() { return currency; } public void setCurrency(Currency currency) { this.currency = currency; } @Id @GeneratedValue public Long getId() { return id; } public void setId(Long id) { this.id = id; } } And a class that has a list of Accounts: @Entity(name="Business") public class Business implements SecurityChecks { private Long id; private String name; private List<Account> accounts = new ArrayList<Account>(); @Id @GeneratedValue public Long getId() { return id; } public void setId(Long id) { this.id = id; } @OneToMany(mappedBy="business", cascade={CascadeType.ALL}) public List<Account> getAccounts() { return accounts; } public void setAccounts(List<Account> accounts) { this.accounts = accounts; } @Column(nullable=false) public String getName() { return name; } public void setName(String name) { this.name = name; } } Here's the definition of Currency: package com.habitsoft.books.model; import javax.persistence.Entity; import javax.persistence.GeneratedValue; import javax.persistence.Id; import javax.persistence.Transient; import com.habitsoft.books.service.client.CurrencyFormatter; @Entity(name="Currency") public class Currency implements Comparable<Currency> { private Long id; private String currencyCode; private String name; private String prefix = ""; private String suffix = ""; private int decimalPlaces; @Id @GeneratedValue public Long getId() { return id; } public void setId(Long id) { this.id = id; } @Override public int hashCode() { final int PRIME = 31; int result = 1; result = PRIME * result + ((getCurrencyCode() == null) ? 0 : getCurrencyCode().hashCode()); return result; } @Override public boolean equals(Object obj) { if (this == obj) return true; if (obj == null) return false; if (getClass() != obj.getClass()) return false; final Currency other = (Currency) obj; if (getCurrencyCode() == null) { if (other.getCurrencyCode() != null) return false; } else if (!getCurrencyCode().equals(other.getCurrencyCode())) return false; return true; } public int compareTo(Currency obj) { if (this == obj) return 0; if (obj == null) return -1; final Currency other = (Currency) obj; return getCurrencyCode().compareTo(other.getCurrencyCode()); } public String getCurrencyCode() { return currencyCode; } public void setCurrencyCode(String currencyCode) { this.currencyCode = currencyCode; } public String getName() { return name; } public void setName(String name) { this.name = name; } } Here's a line of code I use to fetch the Account directly: return em.find(Account.class, accountId); Here's how I fetch the list of accounts for a business: Business business = em.find(Business.class, businessId); return business.getAccounts().subList(offset, offset+limit); What is very, very odd to me is that the Accounts returned by the first form have just a single Balance instance in the map, when there should be two, whereas the ones returned by the second form have both entries I'm expecting. Hibernate prints the following SQL queries: Hibernate: select account0_.id as id270_0_, account0_.business_id as business5_270_0_, account0_.description as descript2_270_0_, account0_.name as name270_0_, account0_.type as type270_0_ from Account account0_ where account0_.id=? Hibernate: select balances0_.account_id as account3_2_, balances0_.id as id2_, balances0_.currency_id as formula5_2_, balances0_.id as id271_1_, balances0_.account_id as account3_271_1_, balances0_.amount as amount271_1_, balances0_.currency_id as currency4_271_1_, currency1_.id as id275_0_, currency1_.currencyCode as currency2_275_0_, currency1_.decimalPlaces as decimalP3_275_0_, currency1_.name as name275_0_, currency1_.prefix as prefix275_0_, currency1_.suffix as suffix275_0_ from Balance balances0_ inner join Currency currency1_ on balances0_.currency_id=currency1_.id where balances0_.account_id=? If I execute these queries against the database manually, the correct number of results is returned, so it seems likely that hibernate is generating the correct query, but then populating the map incorrectly. I took a guess that hashCode() and equals() in Currency were the most likely cause of the issue and indeed if I change them to use id instead of currencyCode the problem goes away. So, for some odd reason hibernate is populating the id field and not the other fields, and then putting it into the Map, but only when the object is fetched directly. This seems to point to some inconsistency in the way hibernate is initializing the objects and maps, somewhere. The workaround is to not use any fields except id in hashCode() and equals() for an entity used as a map key, and to ensure you call persist() on the key objects before putting them into the map. This seems like a reasonable constraint to me, but it would be nice if the behavior was more consistent to avoid excessive head-scratching. -- 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-895) Content assist doesn't work when an entity alias is not preceded by whitespace

by Joseph Marques (JIRA)

Content assist doesn't work when an entity alias is not preceded by whitespace ------------------------------------------------------------------------------ Key: HBX-895 URL: http://opensource.atlassian.com/projects/hibernate/browse/HBX-895 Project: Hibernate Tools Type: Bug Versions: 3.2beta8 Reporter: Joseph Marques In an HQL editor: If I type - "count(col." - and press ctrl+space, I don't get the content assist for col If I type - "count( col." - and press ctrl+space, I do Similarly, If I type - "select a,b." - and press ctrl+space, I don't get the content assist for b If I type - "select a, b." - and press ctrl+space, I do It's pretty clear that the lexing is a little bit too tight here, and that for better usability it should be relaxed. The second case isn't as big a deal as the first (because I don't know a single person that doesn't comma-space delimit the select clause, but I'm thinking that some people that don't realize that they have to put a space in front of it might think that the tools simply can't auto-complete inside functions. -- 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

Support sorting/grouping of the items in the Session Factory section of the Hiberate Configurations view -------------------------------------------------------------------------------------------------------- Key: HBX-880 URL: http://opensource.atlassian.com/projects/hibernate/browse/HBX-880 Project: Hibernate Tools Type: New Feature Versions: 3.2beta8 Reporter: Joseph Marques I'm working with a domain model that has over 100 entities. It would be nice to have a consistent ordering of these items...maybe based off of the fully-qualified class name? It would be even nicer if they could be grouped by their different packages, which is how I've more naturally navigated to them in the past. Of course the packages should also be alpha-sorted, and each each of entities within a package sorted 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-2498) Lazy Inverse Map Bug?

by CannonBall (JIRA)

Lazy Inverse Map Bug? --------------------- Key: HHH-2498 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2498 Project: Hibernate3 Type: Bug Versions: 3.2.1, 3.2.2 Environment: Hibernate 3.2.2, Java5, MySQL 5 (InnoDB) Reporter: CannonBall Priority: Minor Mapping documents: <hibernate-mapping> <class name="scratchpad.hibernate.A"> <id name="id"> <generator class="assigned"/> </id> <map name="bs" cascade="all-delete-orphan" inverse="true"> <key column="aId"/> <map-key type="long" column="cId"/> <one-to-many class="scratchpad.hibernate.B"/> </map> </class> <class name="scratchpad.hibernate.B"> <id name="id"> <generator class="assigned"/> </id> <many-to-one name="a" class="scratchpad.hibernate.A" column="aId"/> <many-to-one name="c" class="scratchpad.hibernate.C" column="cId" not-null="true"/> </class> <class name="scratchpad.hibernate.C"> <id name="id"> <generator class="assigned"/> </id> </class> </hibernate-mapping> Code between sessionFactory.openSession() and session.close(): long aId = 1l; long bId = 2l; long cId = 3l; SessionFactory factory = new Configuration().configure() .buildSessionFactory(); try { Session s = factory.openSession(); try { Transaction tx = s.beginTransaction(); try { C c = new C(cId); s.save(c); A a = new A(aId); B b = new B(bId); b.setC(c); b.setA(a); a.getBs().put(cId, b); s.save(a); tx.commit(); } catch (Exception e) { try { tx.rollback(); } catch (Exception e2) { // do nothing } throw e; } } finally { s.close(); } s = factory.openSession(); try { Transaction tx = s.beginTransaction(); try { A a = (A) s.load(A.class, aId); a.getBs().remove(cId); tx.commit(); } catch (Exception e) { try { tx.rollback(); } catch (Exception e2) { // do nothing } throw e; } } finally { s.close(); } } finally { factory.close(); } Name and version of the database you are using: MySQL 5.0.33 The generated SQL (show_sql=true): Hibernate: select b_.id, b_.aId as aId1_, b_.cId as cId1_ from B b_ where b_.id=?

I've been having a confusing problem shown above, whereby A has a Map of Bs indexed using the id from an association with C. This Map is inversely mapped for A and with 'Cascade Delete Orphan'. In the second opened session above, where B is removed from A's Map and thus orphaned, B will not be deleted. I have observed B is only deleted if I either set 'lazy="false"' for A's Map or make an interaction with A's Map in the code (before B's removal) like 'a.getBs().get(cId)'. I suspect the lazy intializer is not initializing correctly in the above scenario. The above scenario does not happen if A's Map is not inversely mapped but B's many-to-one with A is. Can somebody shed some light on whether this is me using Hibernate incorrectly or is a bug? -- 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
