0.44.0

Infrastructure:

• Kotlin 1.9.10
• Kotlin Coroutines 1.7.3
• log4j2 2.20.0
• h2-database driver 2.2.220
• MariaDB driver 2.7.9 and 3.1.4
• MySQL driver 8.0.30
• PostgreSQL driver 42.6.0
• SQLite driver 3.43.0.0
• Spring Framework 6.0.11
• Spring Boot 3.1.3

Breaking changes:

• SpringTransactionManager no longer extends DataSourceTransactionManager; instead, it directly extends AbstractPlatformTransactionManager. The class also no longer implements the Exposed interface TransactionManager, as transaction operations are instead delegated to Spring.
• spring-transaction and exposed-spring-boot-starter modules now use Spring Framework 6.0 and Spring Boot 3.0, which require Java 17 as a minimum version.
• A table that is created with a keyword identifier now logs a warning that the identifier's case may be lost when it is automatically quoted in generated SQL. DatabaseConfig now includes the property preserveKeywordCasing, which can be set to true to remove these warnings and to ensure that the identifier matches the exact case used.

0.41.1

Infrastructure:

• Kotlin 1.7.21
• spring-security-crypto 5.7.3
• Few improvements in text infrastructure with help of valery1707

Deprecations:

• StatementInterceprot.afterCommit and StatementInterceptor.afterRollback without transaction parameter have ERROR deprecation level
• Column<*>.autoIncSeqName has HIDDEN deprecation level
• Database.connect with datasource: ConnectionPoolDataSource parameter has HIDDEN deprecation level
• SchemaUtils.createFKey with reference: Column<*> parameter has ERROR deprecation level
• Sequence.nextVal has ERROR deprecation level
• SqlExpressionBuilderClass has ERROR deprecation level
• CurrentDateTime() has ERROR deprecation level

Feature:

• [PostgreSQL] NOWAIT/SKIP LOCKED modes supported in all kinds of FOR UPDATE. Also, it's now possible to provide tables to be locked (#1623) *ExposedBlob now wraps InputStream instead of ByteArray that can lead to significant memory improvements (#1617)
• [H2] All compatibility modes are fully supported for known dialects (#1615)
• mod/rem operations with EntityID expressions supported with help of Alexey Soshin (#1597)

Bug Fixes:

0.40.1

Infrastructure:

• Kotlin 1.7.20

Feature:

• Read-only transactions/connections support. Read-Only option can be set on all levels (via DatabaseConfig, transaction, TransactionManager). Thanks Alex Shubert for the improvement
• Table.deleteWhere now captures receiver table and allows to omit the table in a lambda. Greetings to Alexey Soshin for the first PR in the project!
  • Breaking change: Code using deleteWhere with eq will need to import org.jetbrains.exposed.sql.SqlExpressionBuilder.eq. Lambdas previously using an implicit it reference from an outer scope will also need to introduce an explicit name to access that binding.
• New mediumText and largeText columns were introduced by Alex Shubert to allow use more suitable data types for databases where they are supported.
• ForUpdateOption (like ForUpdateOption.PostgreSQL.ForKeyShare) added for more flexible management of locks in your SELECT queries. You can set it as a parameter via Query.forUpdate function. Another kudos goes to Alex Shubert
• Preserve a colection type for Iterable.with() function
• LazySizedCollection can be checked for loaded data with LazySizedCollection.isLoaded(). Added by unbearables

Bug Fixes:

• [Regression] NoSuchMethod error: long kotlin.time.TimeSource$Monotonic.markNow (#1556)

0.38.2

Infrastructure:

• Kotlin Coroutines 1.6.1

• h2-database 2.1.212
• MaridDB driver 2.7.5
• MySQL driver 8.0.28
• PostgreSQL driver 42.3.3

Feature:

• New optimizedLoad param introduced for EntityClass.warmUpLinkedReferences. It will force to make to two queries to load ids and referenced entities separately. Can be useful when references target the same entities. That will prevent from loading them multiple times (per each reference row) and will require less memory/bandwidth for "heavy" entities (with a lot of columns or columns with huge data in it)

Bug Fixes:

• Regression on 0.38.1 - SpringTransactionManager requires DatabaseConfig (#1488)
• inList/notInList doesn't work with list of EntityIDs (#1490)

• Allow to pass DatabaseConfig in SpringTransactionManager. PR by stengvac
• CompoundBooleanOp (AndOp and OrOp) is sealed class now
• Entity explicit constructor lambda can be defined on EntityClass via entityCtor parameter to prevent using reflection (for example). Improved by m-sasha
• memoizedTransform function similar to transform added. The delegate will cache value on read for the same value from DB.
• Reified versions of enumeration and enumerationByName functions
• CurrentDateTime became object instance

Performance:

• Faster initialization: reflection replaced with regular code in Column<T>.cloneWithAutoInc. Found and fixed by m-sasha
• ResultRow stores evaluated values in local cache
• Prevent unnecessary calls to get current transaction isolation level. Problem located and fixed by shunyy

Bug Fixes:

• Proper handling of Op.NULL in eq/neq and other places, found by naftalmm
• Wrong SortOrder representation in order by and group by
• SQLServer dialect now have default transaction isolation level READ_COMMITTED.
• Unable to use nullable reference with lookup (#1437) fixed by naftalmm
• Wrong behavior when ColumnType returns null on read (#1435), also fixed by naftalmm
• closeAndUnregister makes a thread local transaction manager completely dead (#1476)
• Call to Entity.load for new entities leads to exception (#1472)
• Broken behavior of customEnumeration for Enums with overridden toString (#1475)
• Another attempt to fix optReference column should allow update { it[column] = nullableValue } (#1275)

0.37.3

Bug Fixes:

• Many-to-many reference broken in version 0.37.1 (#1413)
• NPE on Enum columns initialization

0.37.2

Features:

• adjustHaving, andHaving, orHaving extension methods for Query added by naftalmm

Bug Fixes:

• Change default for logTooMuchResultSetsThreshold to 0 (no log)

0.37.1

Infrastructure:

• Major test infrastructure rework by naftalmm. Now it's possible to run tests on any dialect directly from IDE.
• Kotlin 1.6.10
• Kotlin Coroutines 1.6.0
• kotlinx-datetime-jvm 0.3.1
• Spring framework 5.3.13
• Spring boot 2.6.1
• Detekt 1.19.0

Performance:

• Cache enumConstants values in EnumerationColumnType and EnumerationNameColumnType as it makes copy on access
• Better handling for opened result sets

Features:

• H2 2.x supported
• Composite foreign key supported by naftalmm. Check the sample below.

object ParentTable : Table("parent1") {
    val idA = integer("id_a")
    val idB = integer("id_b")
    override val primaryKey = PrimaryKey(idA, idB)
}

object ChildTable : Table("child1") {
    val idA = integer("id_a")
    val idB = integer("id_b")

    init {
        foreignKey(
            idA, idB,
            target = ParentTable.primaryKey,
            onUpdate = ReferenceOption.RESTRICT,
            onDelete = ReferenceOption.RESTRICT,
            name = "MyForeignKey1"
        )
        
        // or
        foreignKey(
            idA to ParentTable.idA, idB to ParentTable.idB,
            onUpdate = ReferenceOption.RESTRICT,
            onDelete = ReferenceOption.RESTRICT,
            name = "MyForeignKey1"
        ) 
    }
}

• Now it's possible to use embedded entity initialization like:

val post = Post.new {
    parent = Post.new {
        board = Board.new {
            name = "Parent Board"
        }
        category = Category.new {
            title = "Parent Category"
        }
    }
    category = Category.new {
        title = "Child Category"
    }

    optCategory = parent!!.category
}

• New DatabaseConfig.logTooMuchResultSetsThreshold param added to log when too much result sets opened in parallel in the single transaction

Bug fixes:

• Providing a String ID to DaoEntity.new(EntityId) makes Exposed "forget" about the last field passed to the new call (#1379)
• Proper column name casing change for SchemaUtils.addMissingColumnsStatement. PR by spand
• Incorrect behavior of TransactionManager.closeAndUnregister when calling from different threads (#1387)

Bug fixes:

• Prevent too aggressive entity cache invalidation
• Foreign Key with camel-case name throws java.util.NoSuchElementException. Fixed by sultanofcardio
• Union of queries with differently derived columns loses the derived columns (#1373)

0.36.1

Deprecations:

• NotRegexpOp/notRegexp was removed
• ResultRow.tryGet was removed
• ResiltSet.create(rs: ResultSet, fields: List<Expression<*>>) was removed
• Seq data class was removed
• EntityID, IdTable, IntIdTable, LongIdTable, UUIDTable from org.jetbrains.exposed.dao package were removed
• All classes and functions from org.jetbrains.exposed.sql.java-time were removed in favour to org.jetbrains.exposed.sql.javatime
• Column.primaryKey function was removed in favor to explicit Table.primaryKey declaration

Breaking Changes:

• All inheritors of IdTable (IntIdTable, LongIdTable, UUIDTable) have their id and primaryKey fields are final

Features:

• DatabaseConfig.defaultSchema was introduced to set schema before first call in transaction
• Coalesce now accepts any number for arguments

Bug fixes:

• EntityCache was reinitialized on explicit Transaction.commit

0.35.3

Bug fixes:

0.35.2

Feature:

• DatabaseConfig.explicitDialect param added to predefine dialect for a Database

Bug fixes:

• NULL FIRST/LAST sorting in queries with new SortOrder options (#478, #1343). Many thanks to erwinw for a PR
• A new way to configure common settings for a database via DatabaseConfig ():

// An example with current available settings and their defaults
val dbConfig = DatabaseConfig {
    sqlLogger = Slf4jSqlDebugLogger
    useNestedTransactions = false
    defaultFetchSize = null // unlimited
    defaultIsolationLevel = -1 // DB specific
    defaultRepetitionAttempts = 3
    warnLongQueriesDuration = null // no long query tracing
    maxEntitiesToStoreInCachePerEntity = Int.MAX_VALUE // unlimited 
    keepLoadedReferencesOutOfTransaction = false
}
// databaseConfig available on each connect/connectPool functions
val database = Database.connect(datasource, databaseConfig = databaseConfig)

• It's possible to limit the number of entities stored in EntityCache via maxEntitiesToStoreInCachePerEntity config parameter #1302
• References can be stored within an Entity with enabled keepLoadedReferencesOutOfTransaction config parameter. It will allow getting referenced values outside the transaction block.
• INSTERSECT and EXCEPT set operators supported (#402)
