Change history for XBlock

These are notable changes in XBlock. This is a rolling list of changes, in roughly chronological order, most recent first. Add your entries at or near the top. Include a label indicating the component affected.

0.3

  • Change the user field of Scopes to be three valued, rather than two. False is now UserScope.NONE, True is UserScope.ONE, and UserScope.ALL is new, and represents data that is computed based on input from many users.

  • Rename ModelData to FieldData

  • Rename ModelType to Field

  • Split xblock.core into a number of smaller modules: xblock.core: Defines XBlock xblock.fields: Defines ModelType and subclasses, ModelData, and metaclasses

    for classes with fields

    xblock.namespaces: Code for XBlock Namespaces only xblock.exceptions: Exceptions used by all parts of the xblock project

  • Changed the interface for Runtime and ModelData so that they function as single objects that manage large numbers of XBlocks. Any method that operates on a block now takes that block as the first argument. Blocks, in turn, are responsible for storing the key values used by their field scopes.

  • Changed the interface for model_data objects passed to XBlocks from dict-like to the being cache-like (as was already used by KeyValueStore). This removes the need to support methods like iteration and length, which makes it easier to write new ModelDatas. Also added an actual ModelData base class to serve as the expected interface.
