ChangeLog for Avalon Excalibur 4.0b4
- Fixed race condition brought to my attention by Tom Klaasen. His excellent analysis of the problem enabled me to not only fix the race condition but also increase the efficiency of the pool in some cases by 200%[BL]
- Added new InformixDataSource that uses the Informix JDBC 2.2 driver and Cadastre to provide pooled connections from Informix. Unfortunately the drivers do not yet support transactions. I need to look further into this, as it might be a server configuration issue as opposed to a driver issue.[BL]
- Fixed errors in utilities discovered by the tests.[BL]
- Converted tests from Testlet to JUnit.[BL]
- Fixed the build structure so that everything builds correctly.[BL]
- Added extra convenience methods to discover if a component exists.[BL]
- Added stylesheet to convert Stylebook markup to DocBook markup.[BL]
- Changed the documentation build process to use Cocoon to build the site.[BL]
- Add new configuration element "driver" to JdbcDataSource so that the class is loaded in the current context classloader when the component is first set up.[BL]
- Optimize all logging functions to make it easier for JVMs to decide whether or not to concatenate strings for log messages.[BL]
- Extensive reworking of the excalibur.i18n package (XML Resource bundles).[NP]
- Extensive additions to IOUtils so that it accepts numerous different stream/writer types. Also will convert streams to strings using a specific encoder or else by using default platform encoder.[JT]
- Added EndianUtil to excalibur.io to help when need to work with little endian data.[PD]
- Added "ROLE" attribute to DataSource--to comply with practices outlined in whitepaper.[BL]
