- added FileLog which stores content to the file log - now Log is only a wrapper - it puts messages to the local buffer and when logsave is used then the buffer is put to FileLog - new base classes: WinixBase (Log, Config*, Synchro*) WinixModel : public WinixBase (morm::ModelConnector*, Plugin*) WinixSystem : public WinixModel (System*) WinixRequest : public WinixSystem (SLog, Cur*) - singletons: log, slog, plugin are depracated - now references to them are in base classses (WinixBase, WinixModel) - DbBase, DbConn and Db are depracated - now we are using Morm project (in WinixModel there is a model_connector pointer) each thread will have its own ModelConnector git-svn-id: svn://ttmath.org/publicrep/winix/branches/0.7.x@1146 e52654a7-88a9-db11-a3e9-0013d4bc506e
