@@ -1,24 +0,0 @@-Notes on memory management-----------------------------ForeignPtrs are used wherever possible to make sure we don't have-memory leaks.--However, there is one potential problem with them. If a whole bunch-of database stuff goes out of scope all at once, then the Connection,-Statement, and everything else could become finalizable all at once.-And it is not guaranteed to be finalized in any particular order.--We don't want to have the Connection finalized before the Statements.-This could cause segfaults with some databases.--So we implement a simple reference counting system for the-Connection. Each use -- whether in a Connection or a Statement ---counts as one, and the whole thing is freed when the use count drops-to 0 (the last object using it has been finalized).--That solves almost every problem. We have one more: when somebody-calls disconnect on the parent, we really want to close all open-statements first. So a system of weak refs is used to handle that.-This makes sure that we free things in the proper order for explicit-disconnects as well.
