Welcome, I am a programmer in Comarch (Poland) and I would like to know, what should we (Comarch) do, to release our Custom Storage Engine called CLDB on GPLv2 licence... Our custom storage engine is using MySQL/MariaDB custom storage engine API and some sources from "sql" directory to use with condition pushdown... CLDB is column oriented database... Currently one-threaded... What documents should we have/fill to obtain GPL lecence ?? Should we share our codes and where ?? Thank you for Your answers.. ----------------------------------------------------------------------------- Mateusz Matan IT Security R&D Department, C/C++ programmer ComArch S.A., Al.
