Existing users may have noticed that we renamed version 3.2 to 4.0 as the scope had been vastly expanded. So 4.0.M2 is a direct successor of 3.2M1. There are tons of new features and bug fixes included. Below are just the main highlights. For more details read upgrade-guide.pdf and check out the full release notes further down. - -Cayenne can be downloaded from [here](/download.html). - -### Fluent Type-Safe Query API - -Cayenne now provides a set of new fluent query classes: ObjectSelect, SQLSelect, SelectById. More will be coming in the future releases. Here is a simple example of a query selecting a single object by a given criteria: - - Artist a = ObjectSelect - .query(Artist.class) - .where(Artist.NAME.eq("Picasso")) - .selectOne(context); - - A related addition is positional bindings in Expression, SQLTemplate and the new query classes. Using the new API you'll avoid boilerplate in the most-commonly written Cayenne code, all this with full support for generics and type safety. The "old" style of bean-like queries (SelectQuery) is still supported. - -### Powerful Automated Workflow with 'cdbimport' - -'cdbimport' (a Maven/Ant task that generates DataMap from DB) was always there in Cayenne, just not very usable. In this release it was reworked to become a cornerstone of an automated workflow that allows you to keep mapping and Java classes always in sync with the underlying DB, and yet provide arbitrary customizations to the object layer. - -### OSGI Support - -All Cayenne runtime jars have proper OSGi manifests and can be used as OSGi bundles. Here is a [demo](https://github.com/andrus/cayenne-osgi-example) showing how to write an OSGi Cayenne app. The main trick is to add an OSGi module to Cayenne runtime that will take care of classloading, etc.: - - Module osgiModule = - OsgiModuleBuilder.forProject(Activator.class).withDriver(Driver.class).module(); - -### ServerRuntimeBuilder and Mapping-Free Runtime - -We found that customizing ServerRuntime is a frequent task in most applications. Things like setting a proper DataSource, loading multiple projects into a single runtime, overriding a service here and there are all very common customizations. While all of those can be done via ServerRuntime constructor and custom DI modules, we decided to add some syntactic sugar to streamline configuration. Enter ServerRuntimeBuilder: - - ServerRuntime runtime = new ServerRuntimeBuilder("myproject") - .addConfigs("cayenne-project1.xml", "cayenne-project2.xml") - .addModule(binder -> binder.bind(JdbcEventLogger.class).toInstance(myLogger)) - .dataSource(myDataSource) - .build(); - - While we are on the topic of ServerRuntime, we now also have an ability to start a mapping-free runtime, which turns Cayenne into a powerful SQL execution stack without the ORM part (e.g. useful for unit tests). - -### Transparent Database Cryptography with 'cayenne-crypto' - -Cayenne now includes [cayenne-crypto.jar](http://search.maven.org/#artifactdetails|org.apache.cayenne|cayenne-crypto|4.0.M2|jar), that allows you to implement seamless data encryption. With a bit of extra configuration (as you may have guessed - another DI module) you get automatic encryption/decryption of data in certain columns: - - Module cryptoModule = new CryptoModuleBuilder() - .keyStore("file:///mykeystore", "changeit".toCharArray(), "keyalias") - .compress() - .build(); - - By default columns that start with 'CRYPTO_' are designated as encrypted, but this is [fully customizable](https://github.com/apache/cayenne/blob/master/cayenne-crypto/src/main/java/org/apache/cayenne/crypto/map/ColumnMapper.java). The rest of your application code doesn't need to worry about cryptography, and would look like a regular Cayenne application. - - -### DI Container Decorators - -In addition to overriding services in DI container, now Cayenne would allow to supply decorators. True to the "smallest-footprint" DI philosophy, decorator approach is very simple and does not rely on proxies or class enhancement. Just implement the decorated interface and provide a constructor that takes a delegate instance being decorated: - - public class MyInterfaceDecorator implements MyInterface { - - private MyInterface delegate; - - public MyInterfaceDecorator(@Inject MyInterface delegate) { - this.delegate = delegate; - } - - @Override - public String getName() { - return "<" + delegate.getName() + ">"; - } - } - - Module module = new Module() { - - @Override - public void configure(Binder binder) { - binder.decorate(MyInterface.class).before(MyInterfaceDecorator.class); - } - }; - -### Stability Improvements - -We got rid of the hated "runtime" ObjRelationships that caused random issues, and fixed more than 30 other bugs. - - -### A full list of changes in this release: - -* CAY-1267 Some changes to LogDialog -* CAY-1826 Merge Entity Attributes and Relationships tabs together with one toolbar. -* CAY-1839 Allow to link DataMaps to DataNodes from DataNode editor. -* CAY-1841 Filters for Left-hand project navigator -* CAY-1842 Remove Listeners support from the Modeler -* CAY-1843 DataMap v7: Stop saving listeners in DataMap, add upgrade handler -* CAY-1845 Upgrade javadoc plugin to 2.9.1 -* CAY-1846 Reworking of callback mapping -* CAY-1847 Make ConverterFactory extensible -* CAY-1848 New method: ObjectContext.selectOne(Select query) -* CAY-1851 Generate default serialVersionUID for generated java classes to avoid eclipse warnings -* CAY-1852 Straighten thread model and synchronization in the Modeler -* CAY-1855 Iterated and paginated queries must print result counts -* CAY-1856 Expression.expWithParameters does not work when parameters are placed in the inline collection -* CAY-1860 In-memory matching of DataObjects against ObjectId or int -* CAY-1861 Remove runtime relationships -* CAY-1870 cgen -

If you still need Java 1.6, you can use Cayenne 3.1 or 4.0.M2 until your application is able to upgrade. + +### Java 8 Date/Time and Joda-Time Support + +Cayenne now has two additional modules that contain ExtendedTypes for Java 8 Date/Time and Joda-Time support. You will need to add appropriate dependency and then create a coresponding module and add it to the ServerRuntime. For example: + + Module java8Module = new CayenneJava8Module(); + this.runtime = new ServerRuntime("cayenne-project.xml", java8Module); + +### Improvements in Query API + +All new fluent query classes (ObjectSelect, SQLSelect, SelectById) have the following new methods: + +* `List<T> select(ObjectContext context);` +* `T selectOne(ObjectContext context);` +* `T selectFirst(ObjectContext context);` +* `void iterate(ObjectContext context, ResultIteratorCallback<T> callback);` +* `ResultIterator<T> iterator(ObjectContext context);` +* `ResultBatchIterator<T> batchIterator(ObjectContext context, int size);` + +The "old" style SelectQuery is still supported and also includes these methods. + +Also ResultIterator and ResultBatchIterator are both AutoCloseable now.

If you are using it, you will need to take a few steps to upgrade.

It has always been a challenge to do it in a consistent and convenient manner. We've made a few attempts to solve this before. M3 features new and the most comprehensive solution. There is a [PostCommitBuilder](https://github.com/apache/cayenne/blob/4.0.M3/cayenne-lifecycle/src/main/java/org/apache/cayenne/lifecycle/postcommit/PostCommitModuleBuilder.java) class that helps to create a special DI module with all required extensions for this to work. It allows to register [PostCommitListeners](https://github.com/apache/cayenne/blob/4.0.M3/cayenne-lifecycle/src/main/java/org/apache/cayenne/lifecycle/postcommit/PostCommitListener.java) that will receive an event on every commit, containing a full commit log object. + +### A full list of changes in this release: + +* CAY-1626 Add JodaTime DateTime support +* CAY-1902 Implement resolving Db paths for DataObjects +* CAY-1991 More control over generated String property names +* CAY-1992 Allow to exclude DataMap java class from Modeler class generation +* CAY-1995 Add support for iterators to Select +* CAY-2001 Saving a display state of Project +* CAY-2004 EJBQL: Support for ordering on aggregate expressions +* CAY-2007 Refactoring SelectTranslator for better extensibility +* CAY-2008 Connection pool refactoring and validation query support in Cayenne DataSource +* CAY-2009 Non-blocking connection pool +* CAY-2010 DataSourceBuilder to help users create pooling and non-pooling DataSources +* CAY-2011 Support for Java 8 date and time types +* CAY-2012 ObjectSelect, SelectById: eliminating methods that reset query state +* CAY-2013 In-memory evaluation of DB expressions - non-id attributes +* CAY-2023 Decouple the use of ResourceLocator +* CAY-2025 Support for DBCP2 +* CAY-2026 Java 7 +* CAY-2027 Support for Expression outer join syntax in EJBQL +* CAY-2028 Wrap DataChannelFilter calls in the main transaction +* CAY-2029 Allow out-of-order insertion into DI lists +* CAY-2030 Capturing a stream of commit changes +* CAY-2035 Autobind items added to collections (Cayenne DI) +* CAY-2042 Remove an arbitrary limitation on 1000 runtime DbRelationships +* CAY-2043 ServerRuntimeBuilder: use DataDomain name for the default DataNode +* CAY-2044 Collection setter for to-many relationships +* CAY-2045 Add autosuggestion fields to choose attributes and relationships + +### Bug Fixes: + +* CAY-1977 Cleanup Modeler reverse engineering functionality +* CAY-1987 Widen types before performing in-memory evaluation of qualifiers using j.l.Number subclasses +* CAY-1990 Incorrect display of the raw SQL query in Modeler +* CAY-1993 Reverse Engineering does not work with PostgreSQL database +* CAY-1994 Modeler Migration Tool Shows No Changes +* CAY-1997 Difference in NULL handling inside the path between PropertyUtils and DataObject.readNestedProperty +* CAY-1998 Speeding up PropertyUtils +* CAY-1999 Unneeded Property import for superclasses with no properties +* CAY-2003 cdbimport doesn't work properly with several includeTable tags +* CAY-2015 Joint prefetches combined with DisjointById prefetches return null incorrectly +* CAY-2020 typo: correction to upper alpha range in Rot13PasswordEncoder +* CAY-2041 "cayenne.jdbc.max_connections" and "cayenne.jdbc.min_connections" command line options are ignored +* CAY-2047 Relationship mapping with target inheritance +* CAY-2049 Changing the Relationship name in ObjRelationship Inspector has no effect \ No newline at end of file http://git-wip-us.apache.org/repos/asf/cayenne-website/blob/630c9b22/_posts/2016-03-06-cayenne-40M5-released.md ---------------------------------------------------------------------- diff --git a/_posts/2016-03-06-cayenne-40M5-released.md b/_posts/2016-03-06-cayenne-40M5-released.md new file mode 100644 index 0000000..e18fb46 --- /dev/null +++ b/_posts/2016-03-06-cayenne-40M5-released.md @@ -0,0 +1,104 @@ +--- +layout: post +title: Cayenne 4.0 Milestone 5 Released +date: 2016-3-6 +--- + +Apache Cayenne team is glad to announce the latest milestone of Cayenne - 4.0.M5. +The new release features a number of important things: + +* New fluent API for SQL functions (including long-awaited **aggregate** functions). +* Auto-loading of additional Cayenne modules. +* New JCache module that allows to easily include any compatible cache provider. +* Further improvements and stabilization of database reverse-engineering tools. +* Fixes bugs, updates docs, etc. + +Cayenne can be downloaded from [here](/download.html).

Below are just the main highlights. For more details check out the full release notes further down, as well as [UPGRADE.txt](https://github.com/apache/cayenne/blob/4.0.M3/docs/doc/src/main/resources/UPGRADE.txt). - -Cayenne can be downloaded from [here](/download.html). - -### Java 7 - -Since this milestone minimal Java version is 1.7. If you still need Java 1.6, you can use Cayenne 3.1 or 4.0.M2 until your application is able to upgrade. - -### Java 8 Date/Time and Joda-Time Support - -Cayenne now has two additional modules that contain ExtendedTypes for Java 8 Date/Time and Joda-Time support. You will need to add appropriate dependency and then create a coresponding module and add it to the ServerRuntime. For example: - - Module java8Module = new CayenneJava8Module(); - this.runtime = new ServerRuntime("cayenne-project.xml", java8Module); - -### Improvements in Query API - -All new fluent query classes (ObjectSelect, SQLSelect, SelectById) have the following new methods: - -* `List<T> select(ObjectContext context);` -* `T selectOne(ObjectContext context);` -* `T selectFirst(ObjectContext context);` -* `void iterate(ObjectContext context, ResultIteratorCallback<T> callback);` -* `ResultIterator<T> iterator(ObjectContext context);` -* `ResultBatchIterator<T> batchIterator(ObjectContext context, int size);` - -The "old" style SelectQuery is still supported and also includes these methods. - -Also ResultIterator and ResultBatchIterator are both AutoCloseable now. So you will be able to use try-with-resources with them. - -### Non-blocking DataSource - -Default Cayenne DataSource provider is switched to a non-blocking implementation that has a much better concurrency compared to the old version. - -### DBCP2 - -DBCPDataSourceFactory is now based on DBCP2 (which is required under Java 1.7 and newer). If you are using it, you will need to take a few steps to upgrade. For more details see [UPGRADE.txt](https://github.com/apache/cayenne/blob/4.0.M3/docs/doc/src/main/resources/UPGRADE.txt). - -### Capturing a stream of commit changes - -Sometimes it is very useful to capture all or parts of "commit log" for commits made through Cayenne (for audit purposes, etc). It has always been a challenge to do it in a consistent and convenient manner. We've made a few attempts to solve this before. M3 features new and the most comprehensive solution. There is a [PostCommitBuilder](https://github.com/apache/cayenne/blob/4.0.M3/cayenne-lifecycle/src/main/java/org/apache/cayenne/lifecycle/postcommit/PostCommitModuleBuilder.java) class that helps to create a special DI module with all required extensions for this to work. It allows to register [PostCommitListeners](https://github.com/apache/cayenne/blob/4.0.M3/cayenne-lifecycle/src/main/java/org/apache/cayenne/lifecycle/postcommit/PostCommitListener.java) that will receive an event on every commit, containing a full commit log object. - -### A full list of changes in this release: - -* CAY-1626 Add JodaTime DateTime support -* CAY-1902 Implement resolving Db paths for DataObjects -* CAY-1991 More control over generated String property names -* CAY-1992 Allow to exclude DataMap java class from Modeler class generation -* CAY-1995 Add support for iterators to Select -* CAY-2001 Saving a display state of Project -* CAY-2004 EJBQL: Support for ordering on aggregate expressions -* CAY-2007 Refactoring SelectTranslator for better extensibility -* CAY-2008 Connection pool refactoring and validation query support in Cayenne DataSource -* CAY-2009 Non-blocking connection pool -* CAY-2010 DataSourceBuilder to help users create pooling and non-pooling DataSources -* CAY-2011 Support for Java 8 date and time types -* CAY-2012 ObjectSelect, SelectById: eliminating methods that reset query state -* CAY-2013 In-memory evaluation of DB expressions - non-id attributes -* CAY-2023 Decouple the use of ResourceLocator -* CAY-2025 Support for DBCP2 -* CAY-2026 Java 7 -* CAY-2027 Support for Expression outer join syntax in EJBQL -* CAY-2028 Wrap DataChannelFilter calls in the main transaction -* CAY-2029 Allow out-of-order insertion into DI lists -* CAY-2030 Capturing a stream of commit changes -* CAY-2035 Autobind items added to collections (Cayenne DI) -* CAY-2042 Remove an arbitrary limitation on 1000 runtime DbRelationships -* CAY-2043 ServerRuntimeBuilder: use DataDomain name for the default DataNode -* CAY-2044 Collection setter for to-many relationships -* CAY-2045 Add autosuggestion fields to choose attributes and relationships - -### Bug Fixes: - -* CAY-1977 Cleanup Modeler reverse engineering functionality -* CAY-1987 Widen types before performing in-memory evaluation of qualifiers using j.l.Number subclasses -* CAY-1990 Incorrect display of the raw SQL query in Modeler -* CAY-1993 Reverse Engineering does not work with PostgreSQL database -* CAY-1994 Modeler Migration Tool Shows No Changes -* CAY-1997 Difference in NULL handling inside the path between PropertyUtils and DataObject.readNestedProperty -* CAY-1998 Speeding up PropertyUtils -* CAY-1999 Unneeded Property import for superclasses with no properties -* CAY-2003 cdbimport doesn't work properly with several includeTable tags -* CAY-2015 Joint prefetches combined with DisjointById prefetches return null incorrectly -* CAY-2020 typo: correction to upper alpha range in Rot13PasswordEncoder -* CAY-2041 "cayenne.jdbc.max_connections" and "cayenne.jdbc.min_connections" command line options are ignored -* CAY-2047 Relationship mapping with target inheritance -* CAY-2049 Changing the Relationship name in ObjRelationship Inspector has no effect \ No newline at end of file http://git-wip-us.apache.org/repos/asf/cayenne-website/blob/630c9b22/_posts/2016/05/cayenne-311-released.md ---------------------------------------------------------------------- diff --git a/_posts/2016/05/cayenne-311-released.md b/_posts/2016/05/cayenne-311-released.md deleted file mode 100644 index 19025e8..0000000 --- a/_posts/2016/05/cayenne-311-released.md +++ /dev/null @@ -1,24 +0,0 @@ ---- -layout: post -title: Cayenne 3.1.1 Released -date: 2016-5-16 ---- - -This new maintenance release has a few major bug fixes and improvements. -It can be downloaded from [here](/download.html). - -### A full list of changes in this release: - -* CAY-1862 MySQL - allow specifying a length for TIMESTAMP and TIME columns -* CAY-2042 Remove an arbitrary limitation on 1000 runtime DbRelationships - -### Bug Fixes: - -* CAY-1863 Make determining whether a particular database type supports length adapter-specific not universal -* CAY-1964 Fix convertAdditionalDataMaps() in CayenneGeneratorMojo.java -* CAY-1973 error while generating classes -* CAY-1978 ESCAPE clause should be included in LIKE parenthesis -* CAY-1979 Prefetches on Many-to-Many Relationships with Longvarchar -* CAY-2047 Relationship mapping with target inheritance -* CAY-2049 Changing the Relationship name in ObjRelationship Inspector has no effect -* CAY-2066 Memory leak in ExtendedTypeMap for inner classes \ No newline at end of file http://git-wip-us.apache.org/repos/asf/cayenne-website/blob/630c9b22/_posts/2016/12/cayenne-40M4-released.md ---------------------------------------------------------------------- diff --git a/_posts/2016/12/cayenne-40M4-released.md b/_posts/2016/12/cayenne-40M4-released.md deleted file mode 100644 index 5f48a0e..0000000 --- a/_posts/2016/12/cayenne-40M4-released.md +++ /dev/null @@ -1,147 +0,0 @@ ---- -layout: post -title: Cayenne 4.0 Milestone 4 Released -date: 2016-12-13 ---- - -Apache Cayenne team is glad to announce the latest milestone of Cayenne - 4.0.M.
