Initial commit of the new SPMySQL Framework, which is added to the project and ready for use but not yet integrated. This new framework should provide much of the functionality required from MCPKit and is based around its interface for relatively easy integration. The largest missing component is Hans' structure code which I believe is better placed outside the framework.
From the Readme file: The SPMySQL Framework is intended to provide a stable MySQL connection framework, with the ability to run text-based queries and rapidly retrieve result sets with conversion from MySQL data types to Cocoa objects. SPMySQL.framework has an interface loosely based around that provided by MCPKit by Serge Cohen and Bertrand Mansion (http://mysql-cocoa.sourceforge.net/), and in particular the heavily modified Sequel Pro version (http://www.sequelpro.com/). It is a full rewrite of the original framework, although it includes code from patches implementing the following Sequel Pro functionality, largely contributed by Hans-Jörg Bibiko, Stuart Connolly, Jakob Egger, and Rowan Beentje: - Connection locking (Jakob et al) - Ping & keepalive (Rowan et al) - Query cancellation (Rowan et al) - Delegate setup (Stuart et al) - SSL support (Rowan et al) - Connection checking (Rowan et al) - Version state (Stuart et al) - Maximum packet size control (Hans et al) - Result multithreading and streaming (Rowan et al) - Improved encoding support & switching (Rowan et al) - Database structure; moved to inside the app (Hans et al) - Query reattempts and error-handling approach (Rowan et al) - Geometry result class (Hans et al) - Connection proxy (Stuart et al)
