AuDAO - Release Notes

Release 1.5 - June 10, 2010

Moved to open-source. Caching for GAE implemented. Extended GQL parser.

New Features

• Updated Google App Engine SDK to version 1.3.4
• Local table's config implemented
• Default cache introduced
• 3-level caches for GAE implemented
• Extended GQL Parser standalone library introduced
• Default values for insert operation implemented

Release 1.4 - May 5, 2010

Several bugs fixed. Introduced "transient" columns.

New Features

• Updated Google App Engine SDK to version 1.3.3.1
• Transient columns introduced
• "Full" equality of DTO's implmented
• Multiline comments on DTO classes and their columns are allowed now

Fixed Bugs

• bugfix#7 and #8 - inheritance - when extending DTO's, then copy constructors must be generated and called properly.
• bugfix#10 - GAE transactions - GQL query can participate in a transaction only if it is an ancestor query.
• bugfix#11 - GQL static queries - escaping of the property names did not work.
• bugfix#12 - GWT custom field serializer - the "modified" flags are also serialized.
• bugfix#13 - GAE - Date types must be cropped when inserting and seearching to emulate JDBC behaviour (portability and compatibility issue)

Release 1.3 - March 26, 2010

Support for GWT serialization of DTOs including GAE core classes. New options which control storing properties in GAE datastore. Renamed attribute @key to @gae-parent.

New Features

• Updated Google App Engine SDK to version 1.3.2.
• GWT server <--> client serialization support:
  • Emulation of GAE datastore core classes - liek GeoPt or Key - allows to pass DTOs containing those core classes as fields from server to client
  • DTO - DTO_CustomFieldSerializer - a custom field serializer class can be generated along with the DTO class - reduces amount of the data passed through network. The optimizations are aware of GAE datastore core types (e.g. GeoPt)
• GAE datastore optimizations:
  • enable/disable one-columns default indexes by gae/@unindexed option
  • do not store null values - option gae/@empty
• DTO enhacement - methods equals() and hashCode() cane be generated - you can choose the implementation - see more.
• Renamed the column/ref/@key attribute to column/ref/@gae-parent (GAE parent column key).
• Standalone tools can generate only selective types (DAO, DTO, FACTORY, ...)

Fixed Bugs

• bugfix#5 - update column method signature was anonymous even when the column has defined the @class attribute - e.g. updateColumn(Serializable)

Release 1.2 - February 25, 2010

All GAE core classes are supported now. Unified conventions about DAO method signatures - index and condition finders.

New Features

• Serializable + List : GAE core types added - qualifier 'gae:' in type/@class
• List: qualifier 'table:' is supported in type/@class
• List: explicit index and condition finders - option 'list' forces param type to be a List - exploding (ANDed) conditions
• Dynamic GQL parser expands Collection params into separate (ANDed) filters.
• GQL dynamic and static parsers: operators IN and != are supported now.
• Added @java to params/column attribute - resolving name collisions
• Escaping kind and property names in GQL queries

Fixed Bugs

• GQL Parser Static - fixed date(),datetime(),time() bugs - missing method
• "prop = KEY(..)" bug - now we can filter also normal properties by key functions

Release 1.1 - February 12, 2010

New types introduced. Fixed batch update bug - storing null values.

New Features

• New type byte[] - implemented for MySQL, Oracle and GAE
• New type Serializable - implemented for MySQL, Oracle and GAE
• New type List - implemented for GAE

Fixed Bugs

• In batch update methods - when setting null values, the SQL was not properly formatted (fixed for MySQL and Oracle, not applicable for GAE)

Release 1.0 - February 1, 2010

Dynamic GQL queries for GAE implemented.
Released AuDAO runtime libraries sources including GQL dynamic query parser.
Fixed bugs in GQL to low-level API converter: integer versus float values; filter by __key__, order by __key__.

Release 0.15 - January 27, 2010

Fixed bug in GQL to low-level API converter - Date and Timestamp must be converted to java.util.Date.
serialVersionUID static field can be generated in DTO classes.

Release 0.14 - January 14, 2010

Introduced DAO implementation for Google App Engine using low-level Datastore API (gae).
The old GAE / JDO implementation target renamed to gaejdo.
The documentation was updated.
Fixed bug in DAO update method signatures: not-null enum column type.

Release 0.13 - December 18, 2009

Tweaking DAO classes: root parent of DTO, DAO and DAO Impl classes can be specified. Also enum "Column" can be enabled and disabled.
Introduced ConnectionProvider (API) and PersistenceManagerProvider (API) classes.

Release 0.12 - December 15, 2009

Updated Google APP Engine SDK to 1.3.0
The GAE DTO implementation classes has a common parent again - the bug in JDO is resolved now. The common parent is now GaeJdoAbstractDtoImpl (API).

Release 0.11 - December 14, 2009

AuDAO has a new logo.
Standalone application is now fully JDK 1.5 compatible.
Find by primary key DAO method can be explicitly defined now.
Fixed problem in GAE implementation of findOne/findMany.

Release 0.10 - December 4, 2009

Updated Google APP Engine SDK to 1.2.8. The GAE DTO implementation classes has no more any common parent. In previous SDK 1.2.6 the common parent (AbstractDto (API) was not a problem. But in SDK 1.2.8 the JDO tried to persist even the abstract class.

Release 0.9 - December 3, 2009

Added possibility to configure the DaoFactory methods using new tag <config>.

Documentation improved: added Javadoc, generated source files and compiled classes to all examples. Added new examples.

Fixed dynamic delete. Added reference fk attribute.

Documentation improved: DAO features, all methods and types documented. Crossreference to XSD added.

Release 0.7 - November 19, 2009

GAE: enums are mapped to raw types. Method update( dto ) implemented.

Getting Started documentation finished.

Release 0.6 - November 9, 2009

Added support for multiple queries for different DB types.

Release 0.5 - November 6, 2009

Online generator improved. Added XSD validation.

Release 0.4 - November 3, 2009

"index" condition added; "auto-find" flag added.

Release 0.3 - October 29, 2009
