1- Implement a PDO driver, called sqlite2 2 3- Transparent binary encoding of return values from PHP callback functions. 4 5- Add user-space callback for the authorizer function (this is potentially 6 very slow, so it needs to be implemented carefully). 7 8- Add user-space callback to handle busy databases. 9 10 o Test how robust we are when a user-space function is registered as 11 a callback for a persistent connection in script A, then script B is 12 called that doesn't register the callback but does make use of the 13 function in an SQL query. 14 --> Our test suite doesn't allow us to test persistent connections 15 at this time :/ 16 17- Use later version of built-in library 18 19vim:tw=78 20
