underverse 0.4.0

A zero-configuration, non-distributed, JSON-based document storage and analysis module focusing on the manipulation, grouping and filtering of unstructured data from various sources. MapReduce is also supported for more advanced analysis methods. Query syntax is similar to SQL-Alchemy's filter method.

Change Log - v0.4.0

• Completely rewrote / refactored the object handling to use jsonpickle instead of the v0.3.0 home-grown solution

• The result is much simpler and more robust object handling

• Changed JSON extension functionality to use jsonpickle

• Added new package called handlers

• Added AND / OR predicates for more complex queries

• Test count increased to 86

• Fixed issue with paginate returning empty first page

• MapReduce changes

  • Fixed critcal mapreduce bug in calling reduce

  • Renamed the Verse.reduce function to Verse.simple_reduce

    • This is to maintain compatibility and naming conventions between Verses and SubVerses

    • Added new reduce function to Verse objects which allows map results to be reduced several times without having re-run the map operation.

• Fixed a few small bugs

• Added more exceptions

• Added documentation for map, reduce and mapreduce functionality

Warning

v0.4.0 breaks backward compatibility. This means that v0.4 might have problems loading/reading dumps or sqlite databases that were created with older versions. In-memory databases shouldn’t see any differences. Now using jsonpickle to handle object encoding

Also, I removed the need to call Underverse.create_mappers when decoding objects. As long as the object has been imported things should work automatically.
