query.setLockMode("alias", LockMode.LockMode.PESSIMISTIC_WRITE); does not Lock in PostgreSqlDialect --------------------------------------------------------------------------------------------------- Key: HHH-5654 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5654 Project: Hibernate Core Issue Type: Bug Affects Versions: 3.5.5 Environment: Hibernate 3.5.5-Final PostgreSQL 8.4 Reporter: Peter Buning When you call {{query.setLockMode("alias", LockMode.PESSIMISTIC_WRITE);}} you get a Query with a LockOptions object that has lockMode = LockMode.NONE and a aliasSpecificLockModes-map with an entry "alias" -> LockMode.PESSIMISTIC_WRITE When calling {{query.list()}} you get to the QueryLoader which calls {{dialect.applyLocksToSql(...)}} The LockOptions-Object has still lockMode=LockMode.NONE and a aliasSpecificLockModes-map with the translated alias and -> LockMode.PESSIMISTIC_WRITE As we use PostgreSQL dialect is an instance of PostgreSQLDialect. So you get a ForUpdateFragement-object with the same LockOptions-object. The aliases-String contains the translated "alias". In {{toFragmentString()}} {{getForUpdateString(String aliases, LockOptions lockOptions)}} is called because we have a LockOptions-object. The aliases are ignored in this case, as you can see in the comment:'by default we simply return the getForUpdateString() result since the default is to say no support for "FOR UPDATE OF ..."' But the {{getForUpdateString(LockOptions lockOptions)}} is only looking at the the lockMode-Attribute of the LockOptions-object what has still the value "LockMode.NONE". It results in an empty String as the return value. But it should be " for update" because there's a LockMode.PESSIMISTIC_WRITE in the aliasSpecificLockModes which is ignored in getForUpdateString(LockOptions lockOptions) -- 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
