PAiN. MUD Codebase / News: Recent posts

1) PAiNDB: Collections could be saved separately from object image.This option should be used if collection is not the only field of dbobject, it has size of 20-40 items and dbobject fields are changed often. Saving collection separately will reduce flushing and object backup time inside transactions.
2) PAiNDB: DbObject.provideSchema() is now static method and required for all non-abstract DBObject impls. This allows to import class schema into db without object instantiation.
3) GUITool: fully rewritten, modules concept added.
4) Codebase: more admin console commands.
5) Tinylyb: roles removed: Reset, ResetGroup. SpaceGroup was renamed to Area.
6) Tinylib: 'more' shell implemented(this shell should be used to show multipage output)
7) Tinylib: online builder bugfixing.
8) PAiNDB: fixed bug with error on objects removal with non-empty StringMap type fields.
9) Tinylib: bugs in @build mode fixed. More complete visualization for array-type fields
10) Tinylib: number of small enhancements.
