- Includes all custom code from subclasses CMMCPConnection and CMMCPResult, meaning they have subsequently been removed from the project.
- All previous Sequel Pro specific code in the above subclasses has been removed in favour of the delegate (currently set to TableDocumet) informing the framework of such information.
- All references to CMMCPConnection and CMMCPResult have subsequently been changed to MCPConnection and MCPResult.
- Framework includes MySQL 5.1.36 client libraries and source headers.
- Framework is now built as a 4-way (32/64 bit, i386/PPC arch) binary.
- All import references to <MCPKit_bundled/MCPKit_bundled.h> have been changed to <MCPKit/MCPKit.h>.
- New script 'build-mysql-client.sh' can be used to build the MySQL client libraries from the MySQL source. See the script's header for a list of available options or run it with no arguments to display it's usage.
Note that there are still a few changes to be made to the framework with regard to removing Sequel Pro specific calls to the delegate. These however can be made later on as they have no effect on functionality and are merely design changes.
Also, note that any future development done on the framework should be made to be as 'generic' as possible, with no Sequel Pro specific references. This should allow the framework to be integrated into another project without the need for SP specific code.

appropriately - offering to retry, reconnect, or disconnect. This fixes Issue #93, Issue #69, and Issue #77.
The gory details:
Previously, MCPKit was correctly running mysql_ping to ensure a connection still existed before running a query, and aborted the query if the connection was no longer active.However the code very rarely checked the response of this, so if a query failed subsequent queries would continue to be run and the program would end up checking non-existent results, throwing Cocoa exceptions and generally breaking. However, mysql_ping would also use the default timeout (30 seconds) for each check - when running the (previous to r333) 14 queries to switch tables, this resulted in a long hang before the program even broke.
To exacerbate the issue, certain situations triggered a bug present in mysql_ping in the old client binaries we're using (http://bugs.mysql.com/bug.php?id=9678), causing mysql_ping to never return despite the presence of a timeout, and so causing an indefinite hang.
This issue has been fixed by:
- Setting a new 10 second connection timeout for both new connections (Issue #69) and for mysql_pings. Once preferences have been redesigned we'll probably make this value editable.
- Enforce the 10 second timeout even if mysql_ping hangs by using interrupts.
- Wrap mysql_ping in a new method to do the above and also catch re-established connections without reporting false failures.
- When a connection has failed, prompt the user to Retry, Reconnect, or Disconnect. Reconnect uses the original details for the old connection to establish a new connection, also attempting to preserve the current encoding.
- Do not return control to the main loop until a connection has been reestablished (or disconnected) - this ensures the program is never in a broken state without having to rewrite all query usage.
Much of the above patches the MCPKit connection methods as necessary.
