(aeden) +* Added Thibaut Barrère's encode processor. +* Added MockSource and MockDestination test helpers (thbar) +* Added the block processor. Can call a block once (pre/post processor) + or once for each row (after_read/before_write row processor) (thbar) +* Changed temp table to use new AdapterExtension copy_table method (aeden) +* Added bin/etl.cmd windows batch - just add the bin folder to your PATH + and it will let you call etl on an unpacked/pistoned version of AW-ETL (thbar) +* Upgraded to support Rails 2.1. No longer compatible with older versions of Rails. +* Added ETL::Builder::TimeDimensionBuilder +* Added :default option to ForeignKeyLookupTransform that will be used if no + foreign key is found. +* Added :cache option to ForeignKeyLookupTransform that will preload the FK + mappings if the underlying resolver supports it. Currently supported by + SQLResolver. +* A Class extending ETL::Transform::Transform may now be passed as a transformer. + For example, in the control file you would define the transform as: + transform :a_field, MyTransform, {:option1 => 'option1'}. +* Support Ruby 1.9 CSV library -0.3.0 - Dec 19, 2006 -* Added support for calculated values in virtual fields with Proc +0.9.0 - August 9, 2007 +* Added support for batch processing through .ebf files.

This is not backwards compatible. -* Added HierarchyLookupTransform. -* Added DefaultTransform which will return a specified value if the initial - value is blank. -* Added row-level processing. -* Added HierarchyExploderProcessor which takes a single hierarchy row and - explodes it to multiple rows as used in a hierarchy bridge. -* Added ApacheCombinedLogParser which parses Apache Combined Log format, - including parsing of the - user agent string and the URI, returning a Hash. -* Fixed bug in SAX parser so that attributes are now set when the start_element - event is received. -* Added an HttpTools module which provides some parsing methods (for user agent - and URI). -* Database source now uses its own class for establishing an ActiveRecord - connection. -* Log files are now timestamped. -* Source files are now archived automatically during the extraction process -* Added a :condition option to the destination configuration Hash that accepts - a Proc with a single argument passed to it (the row). -* Added an :append_rows option to the destination configuration Hash that - accepts either a Hash (to append a single row) or an Array of Hashes (to - append multiple rows). -* Only print the read and written row counts if there is at least one source - and one destination respectively. -* Added a depends_on directive that accepts a list of arguments of either strings - or symbols.

An empty hash will be used + if the mapping hash is not specified. If the mapping hash is not specified + then the order will be determined using the originating source's order. +* ActiveRecord configurations loaded from database.yml by the etl tool will be + merged with ActiveRecord::Base.configurations. +* Fixed several bugs in how record change detection was implemented. +* Fixed how the read_locally functionality was implemented so that it will find + that last completed local source copy using the source's trigger file (untested). -0.6.1 - Mar 22, 2007 -* Added support for absolute paths in file sources -* Added CopyFieldProcessor +0.7.2 - Apr 8, 2007 +* Fixed quoting bug in CheckExistProcessor +0.7.1 - Apr 8, 2007 +* Fixed source caching + 0.7 - Apr 8, 2007 * Job execution is now tracked in a database.
