* Consolidates and renames the runtime used as a base for all the others:
* Before: `xmodule.x_module:DescriptorSystem` and
`xmodule.mako_block:MakoDescriptorSystem`.
* After: `xmodule.x_module:ModuleStoreRuntime`.
* Co-locates and renames the runtimes for importing course OLX:
* Before: `xmodule.x_module:XMLParsingSystem` and
`xmodule.modulestore.xml:ImportSystem`.
* After: `xmodule.modulestore.xml:XMLParsingModuleStoreRuntime` and
`xmodule.modulestore.xml:XMLImportingModuleStoreRuntime`.
* Note: I would have liked to consolidate these, but it would have
involved nontrivial test refactoring.
* Renames the stub Old Mongo runtime:
* Before: `xmodule.modulestore.mongo.base:CachingDescriptorSystem`.
* After: `xmodule.modulestore.mongo.base:OldModuleStoreRuntime`.
* Renames the Split Mongo runtime, the which is what runs courses in LMS and CMS:
* Before: `xmodule.modulestore.split_mongo.caching_descriptor_system:CachingDescriptorSystem`.
* After: `xmodule.modulestore.split_mongo.runtime:SplitModuleStoreRuntime`.
* Renames some of the dummy runtimes used only in unit tests.
openedx ------- This directory (openedx) should contain code that is used by both `LMS <https://github.com/openedx/edx-platform/tree/master/lms>`_ and `CMS <https://github.com/openedx/edx-platform/tree/master/cms>`_. If your code is specific to LMS or CMS, put it in those directories instead. Like openedx, the directory `common <https://github.com/openedx/edx-platform/tree/master/common>`_ also contains code used by both LMS and CMS. At some point we'll merge the two. Lastly, the directory `xmodule <https://github.com/openedx/edx-platform/tree/master/xmodule>`_ contains legacy core code, also used by both LMS and CMS. We're in the middle of a long process of phasing that code out. Don't add new code there.
