merged into the 2.5 maintenance branch: - self->statement was not checked while fetching data, which could lead to crashes if you used the pysqlite API in unusual ways. Closing the cursor and continuing to fetch data was enough. - Converters are stored in a converters dictionary. The converter name is uppercased first. The old upper-casing algorithm was wrong and was replaced by a simple call to the Python string's upper() method instead. -Applied patch by Glyph Lefkowitz that fixes the problem with subsequent SQLITE_SCHEMA errors. - Improvement to the row type: rows can now be iterated over and have a keys() method. This improves compatibility with both tuple and dict a lot. - A bugfix for the subsecond resolution in timestamps. - Corrected the way the flags PARSE_DECLTYPES and PARSE_COLNAMES are checked for. Now they work as documented. - gcc on Linux sucks. It exports all symbols by default in shared libraries, so if symbols are not unique it can lead to problems with symbol lookup. pysqlite used to crash under Apache when mod_cache was enabled because both modules had the symbol cache_init. I fixed this by applying the prefix pysqlite_ almost everywhere. Sigh.
