If you've already experimented with 3.1, M2 is a must-have upgrade - it fixes a number of bugs that affected runtime stability (CAY-1515, CAY-1519). If you haven't, maybe it is time to try it out? ;) Usual disclaimer applies about M2 being an early alpha and the new APIs being subject to change. In addition to the numerous bugfixes in the runtime and the Modeler, the new release introduces a set of brand new powerful tools for object lifecycle management. We'll briefly describe them here. Please check Guide to 3.1 Features for more details. + +* Cayenne now allows to declare listener methods with annotations. Configuring listener methods in the Modeler (or via API for that matter) was arguably the most tedious mapping task in Cayenne. What's even worse, if you reuse your model in more than one app, you may not want the listeners to be shared, so you don't want them to be in the model at all. M2 solves that by letting you to annotate the listener class, and registering a listener object where you need it with a single method call. A listener object can of course have multiple annotated callback methods: + + MyListener listener = new MyListener(); + runtime.getChannel().getEntityResolver().getCallbackRegistry().addListener(listener); + +While JPA users may think that lifecycle annotations is old news, Cayenne goes a bit further than JPA here. Cayenne annotations let you attach a listener not just to specific entities, but also to entities whose names are not known to the listener upfront. A listener annotation may reference an arbitrary user-defined annotation which is then placed on entity classes. All of this completely changes how you manage your listeners. It becomes simple, clear and flexible. + +* Another cool lifecycle management tool is DataChannelFilter. A chain of filters can be configured by the user to intercept and react to the data traffic (selects, commits) between DataContext and DataDomain. This was sort of possible before by decorating a DataChannel, however the new approach is much less invasive, and more importantly, the filter object can also have annotated listener methods that are aware of the ongoing select or commit operation. That's what ultimately makes it usable in real-life situations. CacheInvalidationFilter in cayenne-lifeycle module (cayenne-lifecycle is described below) is a good example of how a filter collects some information about an ongoing persistence operation in a ThreadLocal object, and then processes aggregated information at the end of this operation. + +* We are taking advantage of the above feature by providing a cayenne-lifecycle extensions module that implements a few common lifecycle management scenarios - object audit, automated cache group invalidation, and handling a new kind of "to-any" relationship (we tentatively called that one a UuidRelationship). You may use cayenne-lifecycle goodies as is, extend them, or simply refer to it as an example of what is possible with the new lifecycle tools. There's still lots of experimentation going on here, so its API is likely to change. + +Finally, 3.1M2 [download link](/download.html). \ No newline at end of file http://git-wip-us.apache.org/repos/asf/cayenne-website/blob/d2f1e6f3/_posts/2011/06/21/cayenne-302-is-released.md ---------------------------------------------------------------------- diff --git a/_posts/2011/06/21/cayenne-302-is-released.md b/_posts/2011/06/21/cayenne-302-is-released.md new file mode 100644 index 0000000..393d9c1 --- /dev/null +++ b/_posts/2011/06/21/cayenne-302-is-released.md @@ -0,0 +1,27 @@ +--- +layout: post +title: Cayenne 3.0.2 is Released +date: 2011-6-21 +--- + +We just released a maintenance version of stable Cayenne 3.0 branch.

As an object relational mapping library, Cayenne integrates applications to any SQL database available today, freeing solutions from being locked into one database engine. At the same time it improves performance through paging and caching, enforces data integrity and makes it dramatically faster for developers to build a reliable application. + +Cayenne has a track record of solid performance in high-volume environments. Apache Cayenne is an exceptional choice for persistence services, and is in use at ish onCourse, National Hockey League, Nike, Unilever and the Law Library of Congress (the world's largest publicly-available legal index) as well as dozens of high-demand applications and Websites accessed by millions of users each day. + +Apache Cayenne v3.1 is the result of 4 years of development. Notable new features and improvements include: + +* easier configuration and embedding in any type of application; +* highly configurable runtime, enabled by one of the industry's smallest built-in Dependency Injection (DI) containers written specifically for Cayenne (and that co-exists with other DI/IoC, such as Apache Tapestry). It is also very easy to create more than one runtime, which opens interesting possibilities like multi-tenancy; +* nearly all components now pluggable, making it very easy to create more than one runtime and easily change or extend internals of the stack declaratively --from cache provider to SQL log format to DataSource lookup strategy and much more; +* improved ORM modularity to allow projects to be included in libraries without assumptions about the target use. Different aspects of an application can now be modeled in separate mapping projects and combined in runtime as needed. As a result Cayenne projects can be included in libraries that make no assumptions about the target use; +* extended persistent events model from simple per-object events to more higher-level "workflows" that can be configured with app-specific annotations on persistent classes. Cayenne ships with "cayenne-lifecycle" module that provides a few common examples of such workflows activated on data changes: data modifications audit, precision cache invalidation, etc.; and performance optimizations for improved overall concurrency + +"Developers who are seeking an alternate to EJB/Hibernate might find Cayenne's graphical modeler, reverse database engineering, easy to use query API and flexible context model a joy to work with," said Aristedes Maniatis, member of the Apache Cayenne Project Management Committee and CEO of ish. + +"We use Apache Cayenne as the ORM for a large and complex budgeting project for around twenty government organizations," said Daniel Abrams, CEO of MassLight. "Cayenne is used to access and persist exhibit data, business validation rules, and account information, and has simplified the development process. A single Cayenne method call evaluates all changes in the user's context and generates all statements required to commit their changes within a single transaction without the developer having to write code to track the changes -- Cayenne does all the work. Since switching to Cayenne, there haven't been any faulting errors that tended to plague the previous version of the application because of the complex data model. This was one of the principal reasons for the switch to Cayenne and the data model has become significantly more complex now." + +"We use Cayenne in our system to collect, quality control and distribute world coverage nautical charts to navies, pilots, inspectors and several thousand vessels," said Tore Halset, Development Manager at Electronic Chart Centre and PRIMAR. "We have been happy users of Apache Cayenne since 2005 and are now on version 3.1." + +"Apache Cayenne is a core service in Avoka Transact, an engagement platform for multi-channel sales and service transactions," said Malcolm Edgar, Vice President of Engineering at Avoka. + +"We use Apache Cayenne to support the Oracle, MySQL, and SQL Server databases. Cayenne provides the right blend of ORM capabilities and low level JDBC access when required. It has been a rock-solid technology for us." +In addition, Apache Cayenne's HTML documentation and tutorials have been completely revised and available in PDF for the first time. + +"Our comprehensive documentation and vibrant, helpful user community are just what you need when you have questions about the internals of Cayenne or the best way to achieve your goals," added Adamchik. + +### Availability and Oversight +Cayenne v3.1 is available immediately as a free download from [http://cayenne.apache.org/download.html](http://cayenne.apache.org/download.html).

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 -

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/d2f1e6f3/_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 new file mode 100644 index 0000000..19025e8 --- /dev/null +++ b/_posts/2016/05/cayenne-311-released.md @@ -0,0 +1,24 @@ +--- +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/d2f1e6f3/_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 new file mode 100644 index 0000000..5f48a0e --- /dev/null +++ b/_posts/2016/12/cayenne-40M4-released.md @@ -0,0 +1,147 @@ +--- +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.
